Factors to consider when selecting a paper cutter

1. Mechanical structure

The earliest mechanical cutters used a single guide rail structure, the structure is relatively simple, debugging and maintenance is also convenient, but the cutting accuracy is poor, can not meet the requirements of high-level printing on the paper cutting precision, but can not meet the high-end packaging printing products The request.

In the 1950s and 1960s, Italian and German machinery makers at the time started to produce the entire grooveless double-track paper cutter on the platform, which was later replaced by the West German company's dovetail structure. At present, there are also machine manufacturers in the domestic production of dual rail cutter, but its overall structure and performance are not as advanced and practical as Germany's Bora Cutter.

Double-rail paper cutters are cumbersome to adjust accuracy, and they are expensive to replace. The adjustment of the precision of the paper cutter of the dovetail groove structure is simple and convenient. If there is wear during use, only the plug iron can be replaced. Therefore, when selecting a paper cutting machine, it should be determined according to the actual conditions of the product that it is to be processed whether it is a paper cutting machine with a double guide structure or a paper cutting machine with a dovetail groove structure.

2. safety

The paper cutting machine is different from other mechanical products, and safety is the most important issue in the purchase and use of the paper cutting machine. Therefore, when selecting a paper cutting machine, a printer must focus on the safety and reliability of the paper cutting machine. Such as paper cutter paper pressure device with or without a fall arrest device; whether the moving parts are equipped with a fully enclosed safety cover to prevent accidental breakage of parts and cause personal injury; whether the electronic control system (such as electronic knife lock Etc.) to indicate the safety range.

3. Work efficiency and cutting accuracy

The efficiency of the paper cutting machine and the precision of cutting are one aspect that the printing company considers when purchasing the paper cutting machine. In this regard, microcomputer-controlled cutters are superior to ordinary cutters.

The paper feeders of mechanical paper cutters and hydraulic paper cutters are controlled by buttons and hand wheels during forward and reverse operations. In comparison, the operator's labor intensity is relatively large and the efficiency is low. Program-controlled cutters optimize the cutting process and improve work efficiency.

In addition to improving work efficiency, users also demand that the paper with the higher dimensional accuracy be cut with the fastest cutting speed. Therefore, currently the most advanced domestic paper cutters have adopted the most advanced ball screw in the world. Linear Bearings. Its characteristic is stable transmission, high positioning accuracy, accumulative error is greatly reduced, long-term use does not need to adjust the movement gap, and eliminates the impact of the cutting accuracy due to different degree of wear of the guide rail after using the ordinary guide rail in the past. The problem.

4. Service

When selecting a paper cutting machine, it is also necessary to pay attention to a comprehensive measure of the manufacturer's after-sales service and to extend and compare the quality of the manufacturer's products. A good manufacturer will consider whether or not it can distribute the after-sales service network. To enable customers to receive satisfactory service and process technical support in the shortest possible time, the pre-sales, sales-to-sales service quality is a concrete embodiment of the comprehensive capabilities of the paper-cutting machine manufacturers.
