Description

TECHNICAL FIELD

[0001] The present application relates to the field of beverage bottle quality detection, and particularly relates to an automatic quality detection equipment for beverage bottle production. BACKGROUND

[0002] In the large-scale production of the beverage industry, the quality of plastic beverage bottles, as the core packaging carrier of drinks, is directly related to the storage safety, transportation stability of the product and the use experience of consumers, so the quality detection of plastic beverage bottles is very important. Among them, the air tightness detection is one of the key detection items before the plastic beverage bottles are put into the market. If the plastic beverage bottle has a small pinhole, a crack or a defect in the sealing structure of the bottle mouth, it will cause the drink to leak, deteriorate and other problems during storage and transportation.

[0003] At present, the mainstream detection method for the air tightness of plastic beverage bottles in the industry is the pressure gas injection detection method. The principle is to inject a certain pressure of gas into the inside of the plastic bottle to be detected through the gas injection pipe, and monitor the change of the gas pressure in the bottle within the set pressure holding time. If there is a leak, the gas pressure in the bottle will decrease, and the detection equipment captures this change through the gas pressure sensor, so as to determine whether the beverage bottle is qualified. This detection method is widely used in the production lines of various plastic beverage bottles because of its relatively simple operation and high detection efficiency, and has become an important technical means to ensure the quality of bottled beverages.

[0004] However, in the actual production line application process, the above-mentioned pressure gas injection detection method still has obvious technical defects, the most prominent problem of which is that the airtightness between the gas injection pipe and the bottle mouth of the plastic bottle is difficult to guarantee. Since the size of the bottle mouth, such as the diameter and height, will have a certain tolerance due to the slight fluctuation of the injection molding process, such as the difference in raw material melting temperature, mold wear, uneven cooling speed, etc., during the production process of the plastic beverage bottle, and the butt joint size of the gas injection pipe is usually fixed, it is difficult to adapt to the actual size of all bottle mouths. When the size of the bottle mouth is too small or too large, a gap will be formed between the gas injection pipe and the bottle mouth, causing the injected pressure gas to leak from the gap. On the other hand, different sizes of beverage bottles have different sizes of bottle mouths and bodies, and when they are detected, different types of detection devices need to be replaced, which is not convenient to operate.

[0005] Therefore, the present application provides an automatic quality detection equipment for beverage bottle production to solve the above problems. SUMMARY
