Blow-molded bottle air tightness detection equipment and detection method thereof

Abstract

The invention belongs to the technical field of blow-molded bottle production, and aims at solving the problems that when air tightness detection is carried out on a blow-molded bottle at present, manual air blowing is needed to be carried out on the blow-molded bottle and the internal pressure of the blow-molded bottle is manually detected, time and labor are wasted, the detection efficiency is low, the sealing effect of a bottle opening of the blow-molded bottle is difficult to guarantee, and the air tightness detection result is not accurate enough. The invention provides blow-molded bottle air tightness detection equipment and detection method thereof. The equipment comprises an air tightness detection mechanism, a conveying belt is connected with a driving roller and a driven roller, the air tightness detection mechanism is installed at the bottom of a horizontal plate, and a plurality of anti-toppling mechanisms are installed on the conveying belt. The blow-molded bottle is conveyed through the conveying belt, the anti-toppling mechanism can effectively prevent the blow-molded bottle from toppling in the conveying process, air tightness detection can be automatically carried out, manual air blowing and air pressure detection are not needed, the sealing effect on the bottle opening can be remarkably improved, and the detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of blow molding bottle production, in particular to a blow molding bottle air tightness detection device and a detection method thereof. Background technique [0002] Blow molding is also called hollow blow molding. With the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of hollow containers can reach thousands of liters. Some production has adopted computer control. The plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting hollow containers are widely used as industrial packaging containers. According to the production method of the parison, blow molding can be divided into extrusion blow molding and injection molding. Blow molding, newly developed multi-layer blow molding and stretch blow molding, extrusion blow molding is a method of manufactur...

Problems solved by technology

[0005] The object of the present invention is to provide a blow molding bottle air tightness detection equipment and detection method thereof, the blow molding bottle is transported through the conveyor belt, and the anti-dumping mechanism can effectively prevent the blow molding bottle from toppling during the transportation process, which is conducive to continuous Continuously carry out air tightness testing on blow-molded bottles, which significantly improves the detection efficiency. The bottle mouth is initially sealed by the pressure plate and the annular groove, and the bottle mouth is sealed by expanding the hollow expansion ring and pressing the inner wall of the bottle mouth tightly. The secondary seal significantly improves the sealing effect on the bottle mouth, the detection result is more accurate, and it can automatically perform air tightness detection, which is easy to operate, saves time and effort, and solves the problem of It is necessary to manually blow air into the blow-molded bottle and test the internal pressure of the blow-molded bottle, which is time-consuming and laborious, the detection efficiency is low, and it is difficult to ensure the sealing effect of the blow-molded bottle mouth, and the air-tightness test results are not accurate enough.
