Die-cutting indentation is an indispensable process in the post-printing process of carton. As people have higher and higher requirements on the quality of product packaging, the quality of die-cutting indentation will inevitably increase. The flat die cutting method currently occupies a large market share in the domestic die cutting field. Although its technology is very mature, it still inevitably has such problems. Whether it is in the paper part, die-cut part. In the waste removal part, or in the paper collection part, there are many problems that plague the employees in the packaging and printing industry. Paper feeding part The paper supply of the flat-press die-cutting machine is mainly completed by Feida's paper suction and paper feeding actions. The paper is conveyed by a paper belt with a pressure paper wheel. The following faults will occur during the paper feeding process. 1. Unstable paper feeding, frequent adjustment The fault is mainly for domestic die-cutting machines. Since most of the domestic die-cutting machines do not use a conveyor belt with suction, it is easy to cause paper instability, low paper positioning accuracy, paper guide rollers, paper belts, pressure Paper wool wheel, front stop. Side gauge stoppers are easy to wear. Knocking, edge-trimming, and adjusting the paper before feeding can effectively solve this problem. 2. Don't care about paper feeding There are various reasons for the unsmooth paper feeding, mainly due to paper deformation, the surface of the printed matter is too smooth or caused by other mechanical failures. Since die cutting is the last process in the entire printing process, the paper is easily deformed after being processed in several processes, especially after high temperature and high pressure coating. The deformation of the paper after lamination is more serious. At this time, Feida often cannot feed the paper. The product after glazing and coating is too smooth, it will also cause some difficulties for paper feeding. For the above two situations, experienced operators will make preliminary preparations before loading paper, for example: when loading paper, add some wooden wedges or paper rolls to the paper to keep the paper flat, and pre-punch when loading paper Edge, knocking paper or reducing the speed of the die-cutting machine appropriately can generally avoid this problem. (3) Paper feeding difficulties caused by mechanical failure Mechanical reasons such as insufficient suction force of the Feida nozzle, inappropriate position from the plane on the stack, and inaccurate positioning of the rules, etc. can cause faults such as slanting, double, and empty sheets during the paper transport. As long as the maintenance work of the die-cutting machine and the adjustment of the mechanical parts are usually done, the paper feeding difficulties caused by mechanical failures can be avoided.
