The paper cutter is a necessary processing equipment for printing enterprises. When purchasing a paper cutter, you should pay attention to the following issues. 1. Security The paper cutter is different from other mechanical products and belongs to the four-level risk machine tool with the highest risk level. When selecting a cutter product, it is important to investigate its safety and reliability. Such as whether the paper cutter presser has a fall prevention device; whether the moving parts can be equipped with a fully enclosed safety cover to avoid accidental breakage of parts and components and personal injury; whether the cutter has an infrared electronic control system and electronic safety during operation Knife lock etc. to indicate the safe range. 2. Mechanical structure The earliest mechanical paper cutters used spring pressure for pressing paper and a slider structure for pushing paper. The structure is relatively simple and the commissioning and maintenance are also relatively simple, but the pressure of the paper is low and the cutting accuracy is poor, which cannot meet the high degree of printing The request for cutting precision cannot meet the requirements of medium and high-end packaging and printing products. In the 1950s and 1960s, there was a double-rail paper cutter without a groove on the working platform. Later, it was gradually replaced by the dovetail groove structure of German Bora. At present, some domestic machinery manufacturers also produce double-rail paper cutters, but their overall structure and performance are not as advanced and applicable as the paper cutters of Pola. The paper cutter with double guide rail structure is very troublesome to adjust the accuracy, and the price of changing the guide rail after wear is more expensive, but the operation accuracy of this equipment is high. The precision adjustment of the paper cutter with the dovetail slot structure is simple and convenient. Only the plug iron needs to be replaced after wear, but the accuracy is slightly lower. When choosing a paper cutter, the printing company should choose a dual-rail paper cutter or a dovetail slot cutter according to its own needs and the actual conditions of the products to be processed. 3. Work efficiency and cutting accuracy The working efficiency and cutting accuracy of the paper cutter is an aspect that printing companies think more about when purchasing paper cutters. In this regard, the computer-controlled paper cutter is much better than ordinary paper cutters. The paper pusher of the ordinary paper cutter is controlled by the fine adjustment of the buttons and the hand wheel during the operation of traveling and retreating. The operator has a large labor intensity and low work efficiency. The microcomputer program-controlled paper cutter is programmed to optimize the cutting process and improve work efficiency. While pursuing work efficiency, users also demand the fastest cutting speed to cut out products with higher dimensional accuracy. Therefore, the most advanced paper cutters currently in domestic consumption have adopted the most advanced ball screws and linear guides in the world. Its characteristics are smooth transmission, high positioning accuracy, small cumulative error, no need to adjust the movement gap for long-term work, and eliminates the effect of using common screw and guide rails in the past due to different wear levels of the screw and guide rails The problem of cutting accuracy. 4. Comparison of energy consumption The paper cutters of the same model also need to be compared in the application power of the whole machine. Motor power is not only related to power consumption. Due to the reason of precision matching in the process of machine manufacturing and assembly, it is necessary to choose a motor with a larger power, which is actually a method that cannot be dealt with in the process of mechanical processing and assembly. 5. After-sales service When choosing a paper cutter, it is also necessary to weigh the after-sales services of the consumer manufacturers. A good manufacturer will definitely think about the distribution of after-sales service outlets to enable customers to receive satisfactory service and technical support in the shortest time. The quality of service before, during and after sales is cutting paper The detailed performance of the comprehensive capabilities of the machine manufacturer. In addition, the paper cutter should pay attention to the following details when applying. The first is the choice of cutting blade angle. This is a very important part of the cutting work. A good paper cutter should be equipped with a good blade and sharpening process. However, many paper cutter users often neglect this point. As a result, the blade sharpening method, method, and angle are not correct, and the cutting accuracy is not enough. More seriously, the impact force during cutting increases and the safety screw is loose, even broken, and finally formed mechanical injury. In addition, the range of cutting data of the paper cutter is getting wider and wider, and different problems will be encountered during the cutting process. For example, aluminum foil labels and carbon-free carbon paper forms are easy to show indentation during cutting, while PVC and magnetic cards will show that the paper presser cannot hold down during cutting, which leads to cutting out waste products. These problems can be solved by automatic pressure reducing valve to adjust the pressure of the paper press, improve the blade sharpening angle and blade material (such as high-speed steel) and the cutting drive system.
