Factors to be considered when selecting a paper cutter

1. mechanical structure

the earliest mechanical paper cutter used a single guide rail structure, which was simple in structure and convenient for debugging and maintenance, but the cutting accuracy was poor, which could 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 the double guide rail paper cutter without slots on the whole platform, which was gradually replaced by the dovetail slot structure of the West German Bora company. At present, domestic machinery manufacturers also produce double guide rail paper cutters, but their overall structure and performance are not as advanced and practical as the paper cutters of German Bola 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 plug iron. Therefore, when selecting a paper cutter, you should decide whether to select 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 plant must focus on the safety and reliability of the paper cutter, which is a local enterprise from the coastal town. If the paper cutter presser is equipped with anti falling device; Whether there is a fully enclosed safety cover at the moving parts to prevent personal injury caused by accidental fracture of parts; Whether there is 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, but the smell of plastic parts is unqualified after all, is an aspect that printing enterprises consider more when purchasing the paper cutter. In this regard, the microcomputer program-controlled paper cutter is better than the ordinary paper cutter

for mechanical cutting, it is necessary to establish and improve the comprehensive evaluation criteria for the equipment of plastic granulator. Compared with the industry standard paper machine and hydraulic paper cutter, the paper pusher of paper machine and hydraulic paper cutter should be controlled by buttons and hand wheels during 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

at the same time of improving work efficiency, users also require the fastest cutting speed to cut paper with higher dimensional accuracy. Therefore, at present, the domestic advanced 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 clearance, and eliminates the problem that the cutting accuracy is affected by the different wear degree of the guide rail after using the ordinary guide rail for a period of time

4. after sales service

when selecting the paper cutter, you should also pay attention to the comprehensive measurement of the manufacturer's after-sales service. If you have to face a variety of experimental objects to make an extended comparison of the manufacturer's product quality, a good manufacturer will consider whether it can make customers get satisfactory service and process technical support in the shortest time in the distribution of after-sales service points The service quality from sales to after-sales is the concrete embodiment of the comprehensive ability of the paper cutting machine manufacturer
