Shaping and setting processing machine for plastic bottles after blow molding

Abstract

The invention provides a shaping and setting processing machine for plastic bottles after blow molding. The shaping and setting processing machine comprises a workbench, a clamping device and a shaping device. The shaping and setting processing machine can solve the following problems still existing in the plastic bottle blow molding process: a, most plastic bottles are produced and manufactured through assembly line equipment at present, so that the blow molding of the plastic bottles need to be quickly finished in a short time, and the high-temperature plastic bottles need to be quickly cooled to be shaped after being subjected to blow molding, and due to thermal expansion and cold contraction, the plastic bottles are easy to sink and deform, so that the defective rate of the plastic bottles subjected to blow molding is relatively high; and b, when the plastic bottles are subjected to deformation finishing by existing shaping and setting processing equipment, finishing is carried out mostly through heating and pressure maintaining, and rolling finishing is not carried out on the concave parts of the inner walls of the plastic bottles, so that the inner walls of the plastic bottles are still concave after the plastic bottles are shaped, and the finishing effect is poor.

Description

technical field [0001] The invention relates to the technical field of plastic bottle processing, in particular to a processing machine for plastic bottle shaping and shaping after blow molding. Background technique [0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester PET, polyethylene PE, and polypropylene PP as raw materials. After adding corresponding organic solvents, after high temperature heating, plastic containers are blown, extruded, or injection molded through plastic molds. It is mainly used for liquid or solid disposable plastic packaging containers for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs, etc. Plastic bottles have the characteristics of unbreakable, low cost, high transparency, and food-grade raw materials. [0003] At present, the following problems still exist in the plastic bottle...

AI Technical Summary

Problems solved by technology

[0004] (1) Technical problems to be solved: the present invention provides a processing machine for shaping and shaping plastic bottles after blow molding, which can solve the following problems still existing in the plastic bottle blow molding process: a. At present, most plastic bottle blow molding It is manufactured through assembly line equipment, so plastic bottle blow molding needs to be completed quickly in a short time, which leads to rapid cooling of high-temperature plastic bottle blow molding to make it finalized, and due to thermal expansion and contraction, the plastic The bottle is prone to indentation and deformation, resulting in a high defective rate of blow-molded plastic bottles; b. Most of the existing shaping and shaping processing equipment is used to modify the deformation of plastic bottles by heating and maintaining pressure, and does not modify the plastic bottles. The indentation of the inner wall is trimmed by rolling, resulting in the indentation of the inner wall after the plastic bottle is plasticized, and the trimming effect is poor
