Description

Winding material tail-free cutting mechanism

Technical Field

The utility model belongs to the technical field of the technique of coating machine and specifically relates to a winding does not have material tail and cuts mechanism is related to.

Background

When the coating machine is rolled and automatically cut, a material tail is reserved on a conventional cutter. The material tail is often turned over, so that finished products of dozens of meters or even dozens of meters in the winding core become waste products. Thus, no tail trimming was developed. The existing material tail-free cutting method is roughly divided into the following two types: one is that a brush is added on a common cutter, and after the cutter cuts off materials, the brush brushes the tail of the materials on a paper core. The material tail-free cutting structure is simple, but the effect is not good, the material tail is often not well bonded, the product quality is influenced, and the material tail-free cutting structure is not suitable for high-speed cutting. And a material storage rack is used for ensuring that the material is not moved when cutting, namely zero-speed cutting. This cutting effect is not problematic. The disadvantages are that: the volume is large, the cost is high, if the machine runs at high speed, the storage rack becomes very large, and the manufacturing cost is further improved.
