A pet preform shear gate device

Abstract

Disclosed is a polyethylene glycol terephthalate (PET) bottle embryo sprue shearing device. The PET bottle embryo sprue shearing device comprises a device body; a feeding unit is arranged at the front end of the device body; a material inlet mechanism with a certain slope is disposed at the front end of the feeding unit; the rear end of the feeding unit is connected with a material arranging unit through a sliding way; a sprue shearing mechanism is disposed at the rear end of the material arranging unit; a discharging mechanism is mounted at the rear end of the sprue shearing mechanism. By means of a unique transferring mode of combining a conveying belt transmission mechanism and a roller transmission mechanism, it is guaranteed that products are reasonably arranged; the material arranging unit can guarantee the uniformity of the products which are arranged to the maximum degree, whether the products get stuck or not can be detected, and the reasonableness of the material arranging process is improved; the sprue shearing mechanism can guarantee continuous work of the products; a push mechanism can guarantee that the products effectively enter the discharging mechanism; the sprue shearing mechanism has a certain slope, so that the products conveniently enter the discharging mechanism after being sheared, bottle embryo sprues are automatically shorn off, and waste materials are recycled in a centralized mode; the working efficiency is improved, and stable product quality is guaranteed.

Description

technical field [0001] The invention relates to a bottle blank scissor gate device, in particular to a PET bottle blank scissor gate device. Background technique [0002] PET preform is a typical injection molding product. Because of its strong applicability, it is widely used in daily necessities, daily chemical packaging and other fields. [0003] In the existing technology, the PET preform is prepared first by the preform injection process, then by the stretch blow molding process, and finally by the stripping process. After the preform injection process is completed, in order to make the bottom of the PET preform product highly transparent To prevent crystallization at the bottom and increase the aesthetic appearance of the product, a certain margin is usually reserved at the bottom of the preform, which needs to be cut off to ensure the recovery of raw materials and improve the quality of the product. [0004] However, the above-mentioned disadvantages are: in the proc...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned disadvantages are: in the process of cutting off the bottom margin of the preform, there are uneven cutting, poor cutting, unclean cutting, uneven cutting of the embryo tail, and whitening phenomenon at the bottom, so the tail cutting efficiency is not high and the quality is low. Poor, resulting in low yield, can not effectively form the connection operation
