With the continuous improvement of people's living standards, the demand for packaging is also increasing, which puts forward higher requirements for packaging and printing enterprises. Therefore, packaging and printing enterprises are also constantly updating their equipment to meet the requirements of high-end packaging. As far as the paper cutter is concerned, the demand for the paper cutter in the domestic market is gradually transitioning from the original mechanical paper cutter to the microcomputer program-controlled paper cutter

first, there are several problems to be considered when choosing paper cutters. Paper cutters are mainly divided into three categories, namely: mechanical paper cutters; Hydraulic paper cutter; A microcomputer program-controlled paper cutter integrating hydraulic pressure and infrared optoelectronics, and a cutting production line composed of various auxiliary machines

1. mechanical structure

the earliest mechanical paper cutter adopts a single guide rail structure, which is relatively simple in structure and convenient for debugging and maintenance, but the cutting accuracy is poor, which can not meet the requirements of high-level printing for paper cutting accuracy, let alone the requirements of medium and high-end packaging and printing products

in the 1950s and 1960s, Italian and East German machinery manufacturers began to produce double guide rail paper cutter with no slot on the whole platform, which was gradually replaced by dovetail slot structure of West German Bora company. At present, domestic machinery manufacturers also produce double guide rail paper cutter, but its overall structure and performance are not as advanced and practical as the paper cutter of German Bora company

the paper cutter with double guide rail structure is very troublesome in adjusting the accuracy, and the price of replacing the guide rail after wear is relatively expensive. The paper cutter with dovetail groove structure has simple and convenient adjustment accuracy. Once it is worn in use, it only needs to replace the stopper iron. Therefore, when choosing a paper cutter, you should decide whether to choose a paper cutter with double guide rail structure or a paper cutter with dovetail groove structure according to the actual situation of the product you want to process

2. Safety

the paper cutter is different from other mechanical products. Safety is the primary issue in the purchase and use of the paper cutter. Therefore, when selecting the paper cutter, the printing factory must focus on the safety and reliability of the paper cutter. If there is a fall prevention device in the paper cutter press; Whether there is a fully enclosed safety cover at the moving parts to prevent personal injury caused by accidental fracture of parts; Is there an electronic control system (such as electronic knife lock) to prompt the safety range during the operation of the paper cutter

3. working efficiency and cutting accuracy

the efficiency and cutting accuracy of the paper cutter are one of the aspects that printing enterprises consider more when purchasing paper cutters. In this regard, the microcomputer program-controlled paper cutter is better than the ordinary paper cutter. There is a qualitative lifting

the paper pusher of mechanical paper cutter and hydraulic paper cutter depends on buttons and handwheels to control the forward and backward operations. In comparison, the labor intensity of the operator is relatively high and the efficiency is low. The program-controlled paper cutter improves the working efficiency by optimizing the cutting process

while improving work efficiency, users also require the fastest cutting speed to cut paper with higher dimensional accuracy. Therefore, at present, the advanced domestic paper cutter has adopted the most advanced ball screw and linear bearing in the world. It is characterized by stable transmission, high positioning accuracy, greatly reduced cumulative error, long-term use without adjusting the movement gap, and eliminates the problem of affecting the cutting accuracy due to the different wear degree of the guide rail after using the ordinary guide rail for a period of time in the past

4. After sales service

when selecting the paper cutter, we should also pay attention to the comprehensive measurement of the manufacturer's after-sales service, and make an extended comparison of the quality of the manufacturer's products. A good manufacturer will consider whether it can make customers get satisfactory service and technical support in the shortest time in the distribution of after-sales service points, as well as the quality of pre-sales, in-sales and after-sales service, It is the concrete embodiment of the comprehensive ability of the paper cutting machine manufacturer

II. Problems that should be paid attention to in the use of the paper cutter

although the localization rate of nuclear power in China is stable and the impact testing machine as an automobile testing instrument is improved, in the actual use process, the paper cutter has to face a variety of cutting objects, including leather, plastic, cork floor and PS version, in addition to paper and paperboard. Due to the wide variety of materials to be cut, different paper presses should be used for different materials, and the angle of the cutting edge should also be changed to ensure high-quality cutting products

the choice of cutting edge angle is a very important part of cutting work. In other words, a good paper cutter should be equipped with a good paper cutting blade and grinding process. However, during the after-sales service of the paper cutter, we found that many users of the paper cutter often ignore this point. As a result, the impact force in cutting is increased due to the incorrect grinding method, method and angle of the paper cutter blade, resulting in the loosening and even fracture of the safety screw, and finally mechanical damage

the range of materials that need to be cut by paper cutter is becoming wider and wider, such as beer aluminum foil cap label, carbon free carbon copy paper, honeycomb paperboard, magnetic card, photosensitive film, etc. these materials will encounter different practical problems in the cutting process. For example, carbon free copy paper is prone to indentation during cutting, while magnetic cards and photosensitive films will not be fixed during cutting, resulting in waste products. These problems can be successfully solved by adjusting the pressure of the paper press and improving the blade and cutting transmission system. However, according to the author's understanding, only some domestic paper cutting machine manufacturers can solve all these technologies
