Description
Technical Field
[0001] The utility model relates to the technical field of plastic bottle processing, in particular to an air leakage detection device for plastic bottle processing. Background Art
[0002] Plastic bottles are a common container made of plastic and widely used in various fields. Plastic bottles are made of different types of plastics, the most common of which are polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. These plastic materials have good chemical corrosion resistance, light weight, high transparency, etc. Common application areas include food and beverage packaging, pharmaceutical packaging, personal care product packaging, etc. Because plastic bottles have good sealing properties and chemical stability, they can effectively protect and store the substances in them. Plastic bottles are usually used to package sensitive items such as food, beverages, and medicines. If there is a gas leak in a plastic bottle, it may cause the product to be contaminated by the outside world or the quality to deteriorate, affecting the storage life and safety of the product. By using a gas leakage detection device, the gas leakage problem can be detected early and the problematic bottles can be processed to ensure the quality of the product.
[0003] Traditional plastic bottle leakage detection devices usually use an air pump to inflate the plastic bottle, and the plastic bottle is inserted into a cylinder. The cylinder is filled with water. If bubbles appear in the water, it means that the plastic bottle is leaking, so as to achieve the purpose of quickly detecting plastic bottle leakage. The mechanism of the present invention is reasonable and practical, and the operation is simple and fast. It improves the accuracy of the workers' detection results, brings convenience to the workers' detection work, and improves the workers' work efficiency.
[0004] However, the traditional plastic bottle leakage detection device needs to seal the bottle mouth when inflating the plastic bottle, but the bottle mouths of plastic bottles are of different sizes. When sealing different plastic bottles, the sealing device needs to be replaced accordingly, which wastes detection time and generates additional costs. Therefore, a leakage detection device for plastic bottle processing is proposed to solve the above problems. Utility Model Content

There is no need to replace the corresponding inflation head according to different bottle mouths, which saves replacement time and reduces the use of other corresponding machines. Then the electric push rod 7 is started, and the electric push rod 7 drives the moving plate 6 to move, and then the moving plate 6 drives the holder 5 to move to fix the plastic bottle 3. The clamping fixation can ensure that the plastic bottle 3 maintains a stable position during the detection process, and prevents detection errors caused by the movement or shaking of the plastic bottle 3.

Compared with manual operation, the automated system is more reliable, can provide more consistent inspection results, and reduce quality control risks.
[0037] Working principle: The plastic bottle 3 is transported by the conveyor belt 4, and then the motor 11 is started, and the fixedly connected screw rod 16 is driven to rotate by the motor 11, and then the threaded holder 5 is driven by the screw rod 16 to rise and fall inside the slidingly connected moving plate 6, and adjusted to the appropriate position of the plastic bottle 3 to be detected, and then the electric push rod 7 is started, and the fixedly connected holder 5 is driven by the electric push rod 7 to slide inside the sliding rail 10 to clamp the plastic bottle 3, and then the cylinder 9 is started, and gas is generated by the cylinder 9, and the inside of the plastic bottle 3 is inflated through the connecting pipe 14, and when the gas passes through the airbag 15, it is inflated at the bottle mouth to seal the bottle mouth.
