Background

There has been a long-standing problem in the compounding process of carbon fiber prepreg production. In production, the prepreg with required width is obtained, the redundant parts on two sides of the prepreg are required to be cut, and the edge cutting traditional mode of the prepreg adopts manual hand-operated edge rolling, namely, a worker simply rolls the edge by hand under the condition of no tool assistance. Because the force applied by hands cannot be kept stable, the cloth surface of the prepreg is stressed unevenly and is easy to deform when the edge is cut by rolling, and therefore the production efficiency and the production quality of the prepreg are affected.

Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

As shown in fig. 1, a prepreg shear apparatus according to an embodiment of the present invention includes: trimming mechanism 1, finished product wind-up roll 312 and receipts limit mechanism 3.

Wherein, trimming mechanism 1 is used for cutting the unnecessary rim charge of preimpregnation material. And the finished product winding roller 312 is used for winding the finished product prepreg after the edge cutting is finished. The edge rolling mechanism 3 is used for rolling the edge materials cut by the edge cutting mechanism 1, the edge rolling mechanism 3 comprises an edge material rolling roller 31 and a telescopic arm 32, the rolling roller 31 is connected with the telescopic arm 32, and the telescopic direction of the telescopic arm 32 is parallel to the axis of the rolling roller 31.

In an exemplary embodiment, the trimming mechanism 1 is used to cut the excess portions on both sides of the prepreg, and the prepreg with a predetermined width can be obtained by cutting with the trimming mechanism 1. The trimming unit 1 comprises two relatively movable cutting heads, which comprise a cutter 11 and a circular sleeve 12. Wherein, the axes of the cutter 11 and the circular shaft sleeve 12 are parallel to each other. The distance between the two cutters 11 can be adjusted by moving the two cutter heads of the edge cutting mechanism 1, and the distance is the width of the cut prepreg. The circular sleeve 12 acts as a cushion for the prepreg during cutting, keeping it flat during cutting.
