Die cutting machine in the production process will inevitably encounter some small faults, now we fly die cutting machine to teach you some die cutting machine in the production process to meet some small problems of the solution, you can remember, later encounter small problems can solve themselves, so as not to affect the production schedule.

Die cutting indentation is an indispensable process in carton after printing processing, because people have higher and higher requirements for the quality of commodity packaging, die cutting indentation quality is bound to improve. Flat die cutting method currently in the domestic die cutting field occupies a large market share, although its technology has been very mature, but still inevitably there will be such and such problems. Either in the feed section, die - cutting section. There are a lot of problems in the packaging and printing industry.

Die-cutting is the core of the die-cutting machine, and die-cutting plate and plate is the most basic parts. To ensure high quality die - cutting, die - cutting plate production is very critical. Among them, the open connection point and the sponge adhesive strip are the most able to reflect the production level of technology.

1. Open point open point is in the cutting edge of a certain width of the mouth, in the process of making the carton and scrap local connection together, will not spread out in the process of die-cutting. Originally by operators with their own grinding tools open point, so there are a lot of drawbacks, such as: the size of the point is not the same: open point appear die cutting edge deformation. Now many manufacturers have used the special open point. Take sichuan wuniu company as an example, its working principle is according to the different thickness of the paper, using a variety of thickness of the grinding wheel in the die cutting tool to open the point. In this way, even out of the point size, does not hurt the knife, the depth of moderate. Normally, quantitative 200 ~ 250g/m2 of paper use 0. For 3mm thick grinding wheel, 0 is used for 250 ~ 350g/m2 paper. 4mm grinding wheel, 350 ~ 450g/m2 paper use 0. For 5mm thick grinding wheel, 0 for mounting board or corrugated board. 8mm thick grinding wheel. No matter the size of the point, should be opened in the box more secluded place, so as not to affect the aesthetic.

2. High quality sponge rubber strip with durable elasticity and rapid rebound performance, to ensure the fast return of cardboard and corrugated paperboard, improve the die cutting speed, avoid paper being pulled up. Sponge strip is usually attached to 1mm away from the die cutting knife, and 1.5mm higher than the die cutting knife. According to the hardness, sponge rubber strip can be divided into 25°, 30°, 35°, 55° and 60° arch rubber strip. Due to the improvement of die cutting technology, now has changed in the past a sponge head to the end of the method, generally will be 55 degrees of sponge rubber stick in the narrow slot; The 60° arch tape is attached between the connecting point and the cutting line.

3. Die - cutting bottom plate production die - cutting plate production can be loaded into the die - cutting plate box production die - cutting bottom plate. At present the application of die - cutting substrate mainly manual substrate, indentation strip substrate, fiber substrate and steel substrate several. Manual production of the bottom template, although the speed is relatively slow, die cutting precision is not high, but because there are a lot of packaging live parts, the number of varieties, and manual production of the bottom template cost is low, so there is a certain market demand for manual plate making. It is a fast, flexible and convenient method to make the bottom plate with indentation strip. Fiber bottom die plate and laser die cutting plate with the use of the bottom plate, generally used for long plate or indentation strip is difficult to make small box bottom plate. Steel bottom plate is currently the most stable flat die cutting. The best bottom plate, die-cutting products can be compared to rotary die-cutting products, but usually with sandwich die-cutting or resin fiber die-cutting, so production costs will increase, so usually only in the die-cutting cigarette package such as live parts.
