Semicircular tool cutting assembly for aluminum foil paper

Abstract

The invention discloses a semicircular tool cutting assembly for aluminum foil paper. The semicircular tool cutting assembly comprises two parallel roll shafts, namely the first roll shaft and the second roll shaft. The first roll shaft is provided with a cutting mechanism, and the second roll shaft is provided with a lining roll mechanism. The cutting mechanism comprises a locking block, a tool apron, a tightly-bracing device and a first paper feeding roll, wherein the locking block, the tool apron, the tightly-bracing device and the first paper feeding roll are arranged on the first roll shaft in a sleeving manner in sequence from left to right. A semicircular tool is fixedly mounted at the right side of the tool apron. A blade protection slope of a blade of the semicircular tool faces the tool apron in direction. The lining roll mechanism comprises a locating roll, an annular lining tool and a second paper feeding roll, wherein the locating roll, the annular lining tool and the second paper feeding roll are fixedly arranged on the second roll shaft in a sleeving manner in sequence from left to right. The semicircular tool cutting assembly has the advantages of being reasonable in structure, stable in mechanical performance, high in precision and safe and reliable in operation. The problems that environment-friendly lining paper is not cut stably, and a pull opening of the paper is not cut completely are effectively solved. The cutting stability of each lining paper pull piece is further improved; the product quality is guaranteed; the machine halt problems caused by blockage of the environment-friendly lining paper or paper deficiency are remarkably reduced; and the equipment performance is effectively improved.

Description

technical field [0001] The invention relates to the technical field of aluminum foil paper cutting, in particular to an aluminum foil paper semicircular knife cutting assembly. Background technique [0002] With the rapid development of my country's industry, environmental protection issues have been mentioned to an important position by various industries. In order to meet the needs of social development, in recent years, the tobacco industry has been gradually promoting the use of new environmentally friendly aluminum foil paper. Environmentally friendly aluminum foil paper is a new type of packaging paper for the inner lining of cigarette packs, which is quite different from composite aluminum foil paper. [0003] Environmentally friendly aluminum foil paper, the surface of the base paper is coated with water-based ink, compared with composite aluminum foil paper, the stiffness is not good, the thickness is between 0.05 and 0.07mm, and the weight is between 49 and 63g / ㎡. ...

AI Technical Summary

Problems solved by technology

The round tool holder is divided into two independent semicircular bodies and fixed on the shaft with screws. The tool holder and the shaft adopt a dynamic fit tolerance, which can slide horizontally on the shaft. The tool holder is prone to swing and displacement when the equipment is running. Only relying on the elastic force of the built-in spring cannot guarantee the accurate positioning of the semicircular knife, and the stability of the knife seat is poor, resulting in large fluctuations in the gap between the semicircular knife blade and the lining knife. Since the environmental protection aluminum foil does not have the hardness and stiffness of the composite aluminum foil, When cutting environmentally friendly aluminum foil paper, problems such as unstable cutting and continuous cutting of environmentally friendly aluminum foil paper are prone to occur, and poor cutting of aluminum foil paper will affect transportation and molding, resulting in a large number of aluminum foil paper cigarette packs being rejected

At the same time, due to the thin and soft paper of environmentally friendly aluminum foil paper, and the gap between the two cutters is difficult to adjust accurately during cutting, excessive adjustment is required to ensure the cutting effect, resulting in the wear of the semicircular cutter when using environmentally friendly aluminum foil paper is higher than that of composite aluminum foil. Paper

[0007] 2. The service life of the semicircle knife is short, and it needs to be replaced and adjusted every half a month, and the semicircle knife is embedded in the two creasing roller parts, which is extremely inconvenient to replace and adjust

[0011] Although this technical solution is applicable to the cutting of environmentally friendly aluminum foil paper, it still cannot solve the above problems well
