Blow molding processing treatment method for PP plastic bottles

Abstract

The invention provides a blow molding processing treatment method for PP plastic bottles. The blow molding processing treatment method adopts the following equipment for processing, the equipment comprises I-shaped frames, a conveying table and a shaping device, the lower ends of the I-shaped frames are connected with the existing ground, the I-shaped frames are symmetrically distributed front and back, the conveying table is arranged between the I-shaped frames which are opposite front and back, and the shaping device is arranged above the conveying table. According to the blow molding processing treatment method for the PP plastic bottles, through mutual cooperation of a first motor, a long rod, a sliding block and a fixed rod, limiting shell sleeves do linear opposite movement, and therefore the function of fixing the PP plastic bottles is achieved, the situation that in the blow molding and cooling process, the PP plastic bottles deviate and shake, so that the shaping effect is poor is avoided, then an air cylinder drives a blow molding device to descend, the blow molding device is aligned with the PP plastic bottles for air blowing, and therefore the function of carrying out secondary cooling shaping on the primarily-formed PP plastic bottles can be achieved.

Description

technical field [0001] The invention relates to the field of PP plastic bottles, in particular to a processing method for blow molding of PP plastic bottles. Background technique [0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with various organic solvents added. Plastic bottles are mainly used for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs and other liquid or solid disposables. Plastic packaging containers, plastic bottles have the characteristics of unbreakable, low cost, high transparency, food-grade raw materials, etc. PP plastic bottles are made of polypropylene, after adding corresponding organic solvents, after high temperature heating, through plastic molds Blow molding, extrusion blowing, or injection molding plastic containers, and PP plastic bottles are easily deformed due to high temperature after the initial blow molding, so it is necessary to perform secondary blow mol...

Problems solved by technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with various organic solvents added. Plastic bottles are mainly used for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs and other liquid or solid disposables. Plastic packaging containers, plastic bottles have the characteristics of unbreakable, low cost, high transparency, food-grade raw materials, etc. PP plastic bottles are made of polypropylene, after adding corresponding organic solvents, after high temperature heating, through plastic molds Blow molding, extrusion blow molding, or injection molding plastic containers, and PP plastic bottles are easily deformed due to high temperature after the initial blow molding, so it is necessary to perform secondary blow molding on the initial blow molding PP plastic bottles , so that it can be quickly cooled and shaped, but the existing PP plastic bottle blow molding processing equipment often has the following problems in the process of secondary blow molding and shaping of PP plastic bottles:

[0003] 1. During the secondary blow molding process of the existing PP plastic bottle blow molding processing equipment, the PP plastic bottle is prone to shift and shake, which leads to poor or even failure in the secondary shaping of the PP plastic bottle;

[0004] 2. After the secondary shaping of PP plastic bottles, they are collected one by one, which greatly reduces the efficiency of further processing the shaped PP plastic bottles, and easily leads to high work intensity of the staff, which in turn increases the quality of the PP plastic bottles. Bottle processing costs
