Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a plastic production stretching device. Background Art

[0002] Plastic is a high molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. It can be arbitrarily molded into various shapes and can finally maintain its shape. The material or plastic product can be divided into two categories: thermosetting and thermoplastic. Thermoplastic plastics need to be stretched and extended using a stretching device during production.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN217373451U discloses a plastic production stretching device, which can quickly fix the plastic parts through a set plastic grille, and can adjust the pressing position of the pressing plate according to the thickness of the grille to reduce the deformation of the plastic parts. However, in actual use, the device is more cumbersome because both the thickness and the clamping degree need to be adjusted. In view of this, we propose a plastic production stretching device.
