An automated production line for food plastic packaging

Abstract

The invention discloses an automatic production line for food plastic packaging, which comprises a track and a loading block arranged on the track, a cavity is arranged on the track, and a radiation heater is arranged on the inner wall of the cavity. A plurality of lenses are arranged on the inner wall of the chamber; an air pump matched with the loading block is arranged under the track, a processing groove is arranged on the loading block, and a first push plate is arranged at the bottom of the processing groove , the air pump can drive the first push plate to move upward; there is also a guide rail above the track, and one side of the guide rail is inclined; under the action of the chamber, the thermal energy generated by the radiation heater is used for heat preservation. The sheet is preheated at the initial stage of entering the chamber, shortening the time required for heating the sheet, and improving the processing efficiency of the sheet; under the action of the first push plate, the plastic moves upward after molding, increasing the stability of the rising of the plastic, Avoid the shaking of the plastic during the rising process and protect the finished plastic.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, in particular to an automatic production line for food plastic packaging. Background technique [0002] Blister molding process is a thermoforming processing method. It is a way to make open shell products by using thermoplastic sheets. There is a blister forming machine that can realize the production of open shells, so that the blister forming machine being widely used. [0003] The general steps of blister forming include heating, vacuuming, cooling and retrieving. The plastic sheet needs to be heated to the softening temperature before it can be processed. The heating of the sheet is relatively slow and the heat loss is serious. The sheet is blown out from the mold, but due to the instability of the air flow, it is easy to shake when the sheet is blown out, and it is difficult to collect the finished product, which increases the defective rate.
