Bottle body blowing machine

Abstract

The invention discloses a bottle body blowing machine. The bottle body blowing machine comprises a machine table (1), a front mold (2) and a rear mold (3), wherein the front mold (2) and the rear mold (3) are arranged on the machine table (1). The front mold (2) and the rear mold (3) are provided with mold cavities (4) used for bottle body blowing molding when the front mold (2) and the rear mold (3) are combined. The bottle body blowing machine further comprises an air leakage detecting device used for detecting whether a plastic bottle body molded in the mold cavities (4) leaks air or not. The air leakage detecting device comprises an airflow channel (5) which is formed in the front mold (2) or the rear mold (3) and communicated with the mold cavities (4). The airflow channel (5) is connected with a flexible air pipe (6). An air testing device (7) capable of detecting air in the air pipe (6) is arranged on the machine table (1). The bottle body blowing machine is simple in structure and can conveniently detect whether the plastic bottle body molded in the bottle body blowing machine leaks air or not.

Description

【Technical field】 [0001] The invention relates to a bottle body blow molding machine. 【Background technique】 [0002] At present, the plastic bottles used to hold beverages, oils, etc. on the market are blow-molded by a bottle blow-molding machine. However, the current bottle blow molding machine has the following defects. The structural strength of the formed plastic bottle body is weak at the parting surface where the front mold and the rear mold meet, and leaks are prone to occur, but the current bottle blow molding machine cannot detect Whether there are leaks in the plastic bottle body formed in it, the inspection of the plastic bottle body is carried out after the bottle body is taken out from the blow molding machine and then ventilated or filled with water to test. Such an inspection method requires a lot of labor, complex procedures, and high cost. [0003] Therefore, the present invention is based on the above disadvantages. [Content of the invention] [0004]...

AI Technical Summary

Problems solved by technology

However, the current bottle body blow molding machine has the following defects. The formed plastic bottle body has a weak structural strength at the parting surface where the front mold and the rear mold meet, and leaks are prone to occur, but the current bottle body blow molding machine cannot detect Whether the plastic bottle formed inside has leaks or not, 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.
