A New Air Blowing Knife Roller for Rotary Die Cutting Machine

Abstract

The invention relates to a novel rotary die-cutting machine blowing knife roller. The novel rotary die-cutting machine blowing knife roller comprises a knife roller spindle. A plurality of blowholes are formed in the knife roller spindle. A blade fixing device and a blowing device are detachably installed on the knife roller spindle. The blade fixing device comprises a blade, a blade holder and a blade pressing bar. The blowing device comprises a blowing jig and a wind screening accessory. The blowing jig is installed at the end, provided with the blowholes, of the knife roller spindle. The blowing device is externally connected with a blowing connecting device. The wind screening accessory is installed between the blowing jig and the knife roller spindle. The two ends of the knife roller spindle are further connected with bearings. The novel rotary die-cutting machine blowing knife roller is simple in structure, high in practicability, and capable of being disassembled rapidly and avoiding the knife sticking phenomenon.

Description

technical field [0001] The invention relates to the field of engraving moulds, in particular to a novel air blowing knife roller for a circular die cutting machine. Background technique [0002] The circular die cutter roll was first used in the printing industry, especially in the cigarette package printing and packaging industry, and is a high-efficiency die-cutting tool that replaces flat pressing and punching. Before the 1990s, there was no production technology for such products in China, mainly by importing complete sets of European printing production lines and importing supporting tools. After the 1990s, some domestic companies began to digest and absorb foreign circular die-cutting tool technology. In recent years, the rotary die cutter roll has been used not only in the electronics industry, the hygiene industry, and the printing industry, but also in more and more industries that use flat pressing and flat stamping to roll knife die cutting to speed up the product...

AI Technical Summary

Problems solved by technology

[0003] In the production process, there will be "sticky knife phenomenon". When the roller knife cuts the product due to the inertia of the material and rotation, the product and the knife will rotate together. We call it "sticky knife phenomenon". , this phenomenon often causes the products cut by customers to fail to enter the next process effectively, and the company consumes a lot of manpower and material resources for this, which affects efficiency and customer delivery time, and indirectly brings losses to customers; replacing the cutter roll is also a headache for customers. It is an endless thing, because the replacement of the cutter roller not only delays the customer a lot of time, but also requires professionals to carry out the assembly and debugging, so the customer needs to pay a lot of labor costs
