With the continuous improvement of people's living standards, the demand for packaging is also increasing, which puts higher requirements on packaging and printing companies. Therefore, packaging and printing companies are constantly updating equipment to meet the requirements of high-end packaging. In the case of paper cutters, the demand for paper cutters in the domestic market is gradually shifting from the initial mechanical cutters to microcomputer programmed cutters.
First, several issues that should consider when choosing the paper cutting machine The paper cutting machine mainly divides into three kinds, namely: The mechanical paper cutting machine; The hydraulic paper cutting machine; Sets up the microcomputer control microcomputer paper cutting machine which the hydraulic pressure, the infrared photoelectric electron integrated, It is equipped with a variety of auxiliary equipment consisting of cutting production lines.
1. The mechanical structure of the earliest mechanical paper cutter uses 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 high level of printing on the paper cutting precision requirements, but can not meet the high-end packaging Printing product requirements.
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. The safety cutter is different from other mechanical products. Safety is the most important issue in the purchase and use of the cutter. Therefore, the printer must focus on the safety and reliability of the cutter when selecting the cutter. . 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 cutting accuracy are one aspect that printing companies consider more when purchasing a 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. After selecting the paper cutting machine for the after-sales service, we must also pay attention to the comprehensive evaluation of the manufacturer's after-sales service, and extend and compare the quality of the manufacturer's products. A good manufacturer will consider the distribution of after-sales service outlets. Whether it can enable customers to receive satisfactory service and process technical support in the shortest possible time, the pre-sales, sales-to-sale service quality is a concrete embodiment of the comprehensive capabilities of the paper-cutting machine manufacturers.
Second, the paper machine should pay attention to the use of the problem in the actual use of the process, the paper cutting machine to face the cutting object is a wide variety, in addition to paper, cardboard, there are leather, plastic, cork flooring and PS version Wait. Due to the wide variety of materials to be cut, different paper pressures should be used for different materials. The angle of the cutting edge should also be changed to ensure that high-quality cutting products are obtained.
The choice of cutting edge angle is a very important part of the cutting work. In other words, a good cutter requires a good cutter blade and sharpening process. However, we found in the after-sales service of the paper cutting machine that many users of paper cutting machines often overlooked this point. As a result, the cutting methods, angles, and angles of cutting blades are often incorrect, resulting in increased impact in cutting. Causes the safety screw to loosen or even break, eventually causing mechanical damage.
There is a growing range of materials that need to be cut with a paper cutter, such as beer aluminum foil caps, carbonless copy paper, honeycomb paperboard, magnetic cards, photographic film, etc. These materials will encounter different practical problems in the cutting process. Such as carbonless copy paper is prone to indentation when cutting, and the magnetic card, photographic film will appear in the cutting of the paper holder can not be fixed, resulting in cutting waste and so on. These problems can be solved smoothly by adjusting the pressure of the platen and improving the blade and cutting drive system. However, according to the author's understanding of these aspects of technology, at present, only some paper cutter manufacturers can solve all of them.
