Description

A trimming device for plastic cups

technical field

The invention relates to the technical field of plastic product processing, in particular to a trimming device for plastic cups.

Background technique

Plastic products are a general term for daily necessities and industrial products processed with plastic as the main raw material. Blow molding technology is a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is hot ( or heated to a softened state), placed in the split mold, and immediately after the mold is closed, the compressed air is passed into the parison, so that the plastic parison is inflated and clings to the inner wall of the mold, and the plastic product is obtained after cooling and demoulding. . In the production process of a plastic cup, after demoulding, the mouth of the cup will have flashes. First, the flashes will be removed, and then the process bottle mouth will be processed. Therefore, it is generally necessary to install a flash removal device on the blow molding machine. After the edge is manually trimmed, the efficiency of manual operation of the cutter is low, and the precision is not high, which cannot meet the requirements of some products, and it is easy to fail to meet the requirements due to the unevenness of the bottle mouth.
