Plastic vacuum forming machine capable of conveniently changing pressing sheet

Abstract

The invention relates to the technical field of mechanical equipment, in particular to a plastic vacuum forming machine capable of conveniently changing a pressing sheet. The plastic vacuum forming machine capable of conveniently changing the pressing sheet comprises an engine body, a supporting frame is arranged on the engine body, a fixed assembly and the pressing sheet are arranged between theengine body and the supporting frame, two first inserting grooves are formed in the pressing sheet, second inserting grooves are formed in the groove walls of the inner sides of the first inserting grooves, second protrusions in the fixed assembly are matched with the first inserting grooves in an insertion mode, and clamping plates in the fixed assembly are matched with the second inserting grooves in a plug-in mode. According to the plastic vacuum forming machine capable of conveniently changing the pressing sheet, by mounting the fixed assembly on the plastic vacuum forming machine, the effect of conveniently disassembling and assembling the pressing sheet of the plastic vacuum forming machine is achieved, due to threaded connection between a box body of the fixed assembly and a pistonrod on an air cylinder, plastic forming by the plastic vacuum forming machine cannot be affected, and the problem of inconvenient disassembling and assembling of the pressing sheet in a traditional plastic vacuum forming machine is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a plastic-absorbing machine for conveniently replacing tablets. Background technique [0002] Blister molding machine, also called thermoplastic molding machine, is a machine that absorbs heated and plasticized PVC, PE, PP, PET, HIPS and other thermoplastic coils into various shapes of advanced packaging and decoration boxes, frames and other products. The vacuum suction generated by the vacuum pump will heat and soften PVC, PET and other thermoplastic sheets into various shapes of vacuum covers, blister trays, blisters, etc. through the mold. In long-term use, due to corrosion or wear on the surface, it is necessary to replace the pressing sheet. However, the pressing sheet in the blister machine is disassembled, and the operation process is very inconvenient. In view of this, we propose a suction sheet that is convenient for replacing the pressing sheet. plastic m...
