Description

Technical Field

[0001] The utility model relates to the technical field of film processing equipment, in particular to an on-machine edge trimming equipment. Background Art

[0002] On-machine trimming equipment is a specific process that mainly involves the trimming and recycling of edge waste generated during the processing of film materials. In film processing, irregular waste is often generated at the edge, which needs to be processed through the trimming process. During the trimming process, the waste is cut or trimmed for further processing or recycling.

[0003] The prior art also has the following defects during use:

[0004] 1. In the process of recycling plastic film, the trimming equipment in the prior art mostly collects the waste by rollers. This collection method easily causes some waste to be scattered everywhere, which requires further cleaning and collection. In addition, it is not convenient to clean the materials entering the storage chamber, which affects the subsequent material recovery and processing.

[0005] 2. If the receiving port in the prior art is not at the same horizontal position as the material outlet, the material film may be cut during the recovery process, thereby causing the material film to break. In addition, when the material enters the storage chamber, it is easy for the material to accumulate at the front end of the storage chamber due to the disorderly entry of the material, thereby affecting the negative pressure absorption effect of the material.

[0006] In view of this, we propose an on-machine trimming device to solve the existing problems. Utility Model Content
