It is time for the time of our hardcore stationery horizontal evaluation. There were a lot of friends who gave feedback before, saying that they wanted to see the comparison of the rolling knife products. As a partner of a wooden pole pencil, whether a rolling knife is easy to use, it directly affects the experience of the pencil.
This time I bought a number of rolling knives and pen -cutter products from Huibaijia, UNI, Chenguang, Deli, Zhonglin, Ma Peide, Sanmu, Sima and other brands to make the product design and use experience. Help everyone understand the level of mainstream products on the market today. When buying, you can have a purpose and get a better experience.
Principles of Pencil Knife
At the beginning of the pencil invention, there was still no pencil knife. At the beginning of the 19th century, with the large number of pencils, the rolling knife came into being. The traditional rolling knife consists of blades and scabbard. Insert the scabbard and apply the pressure of the hand to make the surface of the surface generate, and then cooperate with the motion trajectory of the hand roll to achieve the effect of the pen. In the 20th century, the pens were invented, that is, fixed pencils, and changed the position of the movement on the specially designed roller, and then used the shaking method to achieve a more fine -cut pen. Today’s pencil knives are basically made of these two principles.
In order to understand the basic disk of the product, the national standard line of the current pencil knife is still used to analyze.
The current standard of the rolling knife is QB/T 1337-2010, which is the standard for the light industry industry in my country. It leads the drafting as Hangzhou Aihua Stationery. Domestic stationery giants such as broad, capable, and unintentional also participated in it.
There are the following core requirements for traditional rolling knives
The scroll capacity refers to the number of rolled pencils that can be rolled in the pencil. The standard specifications must be able to roll at least 6, and there is no writing defect in the pen core. The thickness of the wood flower is less than 0.4mm, and it is connected.
The leading lead refers to the broken pencils caused by the core of the non -pencil quality defect during the curling process. Six pencils are scrolled, and a broken lead should not occur more than 2 times.
The cone taper refers to the cutting angle of the forming of a pencil. It needs to be 13 ~ 30 degrees. The angle is too thin, and the angle is too large.
The knife stress refers to the scroll of the rolling knife, and the blade should not be ruptured or affecting the cutting of cutting.
The core of the pens hole refers to the diameter of the cone hole port inserted by pencils should not be less than 8mm
The blade needs to be corrosion -resistant. After the corrosion resistance is determined, the corrosion ratio of the blade should be less than 15%
In terms of appearance, the new rolling knife is required to have no visible flaws, rust points, uneven machining marks, and safety in terms of appearance. In terms of safety, the risk of damage to users by sharp knife mouth must be avoided.
In general, the requirements of the rolling knife label are not high, and the core life span only requires one rolling knife to cut 6 pencils. Generally, there will be no roll -knife knife that does not meet the recommended label. ~
The current standard GB/T 22767-2008 manual pens machine is drafted by Deli Group. Doli is also a domestic giant of pen-cutter products. Well-known brands such as Sanmu, New Generation, Qixin and other well-known brands participate.
Compared with rolling knife products, the structure of the pen -cutting machine is relatively complicated. The core device is rolling knife, feed device and rocker arm, and drive through size mechanics.
According to the classification, there are three different modes of irreplaceable pen -cutting machine and adjustable pen cutter, and the feed transmission device.
The appearance requirements are similar to general stationery, and there must be no obvious visible workmanship and flaws.
There are the following requirements in terms of performance
The cutting lead core should not be greater than 3mm, and the cutting wood rod polarization should not be greater than 3mm. The definition of the two polarized cores is shown in the figure, which is that the cutting pencil should be neat.
The rotation circle required for the cutting process of the cutting pencil should be less than 35 laps, and it should not be too time -consuming and laborious.
The angle of the taper of the pencil through cutting and forming is 13 ~ 22 °, and the cutting shape of the tone pencil machine is 13 ~ 30 °
The definition of the cutting angle is the same as that of the roll knife, but from the request, the upper limit of the angle of the ordinary pen is lower. In other words, macroex the pencil cut out of the pen is sharper than the rolling pen knife.
In terms of the pores of the pencil, the feed device and the knife rack pore diameter is not less than 8.3mm
In terms of the diameter of the pen tip, the diameter of the pen tip of the penweighter should not be greater than 0.85mm.
The cutting torque is not greater than 78.5N · mm. In other words, the rotation resistance cannot be too large.
For first -class pens, it is necessary to ensure that more than 5,000 pens can be cut, and the number of 20 pencils is less than 5 times. Therefore, the life and stability of the pen scorching machine should be better than the rolling pen knife.
In summary, the pen -cutting machine is better than the rolling knife from the basic disk. It has more and higher requirements, but it is not as small as the volume of the rolling knife, and the price is relatively high.
The cheap log pencil purchased by 1688 used is divided into triangle and hexagonal models. The mixed test of the use of each rolling knife and pens. Pencil itself is average, and it is quite a test of the hard power of the rolling knife and the pen -cutter.
Narcrodile pen knife
The first rolling knife comes from the gift when I buy a pencil. It can be said that the lower limit of the rolling knife on the market is currently designed. The blade is a bit rusty trace. I also forgot which pencil to buy.
The depth of the wood chips is uneven, the blade is not sharp enough, and the rotation resistance is very large. The two pencils have been tested in a row. The effect of the rolling pen is very uneven. This kind of rolling knife is the core source of the poor impression of the roll knife. The cutting pen is also very unsatisfactory.
Huibaijia standard rolling pen knife
The second roll knife is also from buying pencil gifts, but it was sent to buy Huibaijia pencil. I hit Huibaijia logo and used the slope design from the appearance.
From the perspective of the actual scroll effect, the blade is sharp, saving a lot of effort, and the effect of cutting out is not particularly pointed, but it is very uniform, and the overall feel is quite good. This Huibaijia rolling knife is a domestic product, but the quality is good.
Chenguang Mifei trash can pen knife
The representative of the rolling knife products under Chen Guang, belonging to the series of student stationery, the main student stationery, because the shell design is similar to a trash can, so with this name, the pen chips box is still relatively large. The perception of the blade is average.
The barrel box has a good collection ability, but the head of the knife is also blunt. The cuts are not neat enough. The cutting pen is quite laborious. It is better than the worst roll knife, but it is not recommended.
Xima Metal Rolling Pen Knife
Domestic brand Sima’s metal roll knife, metal is one of the main materials for making shells now. Compared with plastic, the drop resistance is better and stronger. Sima also has a sealed packaging. , But the blade status is obvious.
Judging from the actual experience, this rolling knife has caused the only one -time disconnection of this horizontal evaluation. The quality of the blade is not good, astringent and laborious, but it is very sharp, but the wood is quite uniform. It is also my experience. Negative products.
Mary Metal Rolling Pen Knife
The design of this rolling knife from Ma Peide is quite unique. The all -metal material, the barrel shape, the entire product is quite large, which is equivalent to burning the knife head in the interior. The anti -falling performance is very good. It is a famous French children’s stationery brand, Made in China.
The blade quality is good, and the pen is evenly cut and quite pointed, but it is slightly laborious. Considering the material and relatively low price of its all -metal, I am very recognized by its quality. It is recommended that everyone consider one. product.
Huibaijia double -hole rolling pen knife
Huibaijia’s double -hole pen knife is also domestically produced. At the same time, there is a single hole to choose from. The advantage of the dual hole is to support large diameter pencils, not limited to conventional size. At the same time, there are very large dandruff boxes, the blade is good ~
The actual rolling effect, the two -hole roll knife rolls are more uniform and very sharp. I personally recognize this roll knife.
Palette is a classic rolling knife of Uni. The design is small and concise. Needless to say, the blade texture is very good. Whether it is the back of the knife or the blade mouth, it looks very advanced.
In terms of the actual roll effect, the pen chips are uniform, the blade is sharp, very laborious, and the cut pencil is perfect. This is the best rolling knife in this horizontal review ~
Deli electric rolling pen knife
The design of the Deli Electric Roll Pen Knife is actually relatively simple. The top of the pencil is in the top, and the middle part is the knife head. The bottom is plugged into the battery 5. After inserting the pencil, the knife head will automatically rotate.
This kind of electric rolling pen knife is actually very laborious, but the cutting range cannot be controlled at all. It has been pushed and kept cutting. There is no automatic stop mechanism. The cutting effect can only be said to be medium. I think this effect and damage to the life of the pencil. It is not recommended to make me unable to agree with its product power.
This is a few dollars in this pen -cutter. Basically, it is the most basic style of the pen -cutting product. There is nothing special in design, and it is ordinary.
Actually cutting pen, the resistance is relatively large. Although it is a pen cutter, it is very laborious. You can see that the pen chips are also very thick and large. From the perspective of labor, I don’t recommend buying very cheap pen -cutters.
Sanmu Yilian pen
One of the standard drafting units in the scratcher, one of the domestic giants in the field of pen -cutting device, from the perspective of design, there is nothing particularly dazzling. But the actual plastic texture is better and uses a certain metal decoration.
From the perspective of the actual pens experience, I think the cost -effectiveness of Sanmu is good, the quality of the knife is obvious, the pen chips are delicate, very labor -saving, and the pen tip state is very standard. This is a choice for buying a classic design brushmer.
Dedicated automatic pipe cutter
The automatic lead is to remove the traditional pens device that cuts the pen cutter, which will not destroy the paint surface of some high -value pencils, and the fixture without traditional pen cutters, which can prevent children from risk when using the hand -clipper when using a pen. This capable pen is used to use vertical into the lead design. The entire structure uses a transparent shell. You can see the internal structure inside, which is still handsome.
The cutting effect of the entire pencil is pretty good, but the partial position is relatively obvious, and it is also a more labor -saving one ~
Delicate can block the pen-5 gear-5 gear
Automatic pens plus adjustable gear position, which is a high -end model in the hand -to -hand roller. The adjustable gear is to adjust the thickness of the final cut of the pencil. The design is either called a business style, or it can also be called greasy. The brushed and imitation wood grain and mesh, but I personally think that the appearance is still very good. The gear adjustment is above the joystick.
Looking at the cutting effect of 1 and 5 gear, the thinnest state is not particularly thin. The 5th gear is relatively thick. The roll experience is equally good. In addition to the color lead, I think the function of this gear is more powerful and powerful. I recommend the products. If this one does not use the gear and does not look at the appearance, you can buy cheaper styles.
Zhonglin Electric Roll Pen Knife
Zhonglin is a representative brand of Japanese electric pen cutters. This time I bought a classic plug -in pen -cutter. The entire pen -cutter is very large. The rear part has a large position. Similar to the traditional pen -cutter, it supports three rough details at the tail. The entire machine supports top -stop and stop technology, which will not over -lose the life of the pencil.
The three -gear thickness is shown in the picture. I think the pen -scratch pens should be better, the fine gear is very thin, it can meet the needs of fine strokes. The mid -range is suitable for daily use. Just right. The whole use is very easy, the pen chips are also very delicate, and the quality of the knife head can be visible. However, this rolling knife is particularly large, and the power cord is also growing, so it is only suitable for fixed positions.
This reciprocating test has cut a lot of pencils. To sum up, there are already many excellent products in domestic rolling knives and pen -cutters, and many overseas brands have many products in China. If you buy a scroll pen knife, I personally recommend UNI and Huibaijia. The price is not particularly expensive, and the quality is excellent. Of course, it is more expensive. The quality is not too much, but I think it is too expensive to buy children.
After testing the pen -cutter, the national standard and Sanmu are quite good. The products are quite good. It is worthy of the price. There are also very cheap basic models. You can buy it without brain. If you need some special features, you can buy special models. In the electric pens, the Japanese brand Zhonglin performed very well. It is willing to spend hundreds of pieces.
The horizontal reviews of the two major categories of pen -cutting stationery on the rolling knife and pen -cutter are shared here. This series of articles are also conceiving the next issue of the next issue. ~~
