A bottle body blow molding machine capable of online detection of whether the bottle body is leaking

Abstract

The invention discloses a bottle body blow molding machine capable of online detection of whether the bottle body is leaking air. The air leakage detection device is used to detect the air leakage of the plastic bottle formed in the mold cavity. The air leakage detection device includes an air flow channel connected to the mold cavity on the front mold or the rear mold, and a flexible air pipe is connected to the air flow channel. The machine is equipped with a gas inspection device capable of detecting the gas in the trachea. The gas inspection device includes a bracket on the machine. The bracket is equipped with a cylinder connected to the air pipe. There is also a detection switch on the bracket that can detect the lifting block moving with the piston rod when the piston rod of the cylinder is extended. The detection switch communicates with the alarm on the machine through the controller of the bottle blow molding machine. electrical connection. The invention has a simple structure and can detect on-line whether the bottle body formed therein leaks air.

Description

technical field [0001] The invention relates to a bottle body blow molding machine, in particular to a bottle body blow molding machine which can detect whether the bottle body leaks air on-line. Background technique [0002] Currently on the market, plastic bottles for containing beverages and oils are all blow molded by bottle blow molding machines. However, the current bottle blow molding machine has the following defects. The formed plastic bottle has a weak structural strength at the parting surface where the front mold and the rear mold meet, and leaks are prone to occur. However, the current bottle blow molding machine cannot Detect whether the plastic bottle body formed in it has leaks. The inspection of the plastic bottle body is to take the bottle body out of the blow molding machine and then ventilate or fill it with water for inspection. Such an inspection method requires a lot of labor, complicated procedures, and high cost. [0003] Therefore, the present inv...

However, the current bottle blow molding machine has the following defects. The formed plastic bottle has a weak structural strength at the parting surface where the front mold and the rear mold meet, and leaks are prone to occur. However, the current bottle blow molding machine cannot Detect whether the plastic bottle formed inside has leaks. The inspection of the plastic bottle is to take the bottle out of the blow molding machine and then ventilate or fill it with water.

Such an inspection method requires a lot of labor, complicated procedures, and high costs.
