Description

Technical Field

[0001] The invention relates to the technical field of capping sealing detection, and in particular to a full-automatic capping machine for filling and packaging and a sealing detection system. Background Art

[0002] The fully automatic capping machine is a high-tech packaging production equipment. It is equipped with a precise positioning system and torque control device, which can efficiently and accurately tighten the bottle cap. With the help of advanced servo drive and control system, the equipment can operate continuously at a very high speed, significantly increase the workload of the production line, shorten the production cycle, and meet the needs of mass production. The fully automatic capping machine can complete the capping operation at high speed and continuously, significantly increasing the output of the production line. On an automated beverage filling production line, the fully automatic filling and capping machine can fill thousands of bottles of beverages per hour, greatly improving production efficiency. The fully automatic capping machine can fill a variety of materials of different properties, such as beverages, edible oils, medicines, and daily chemical products.

[0003] The existing fully automatic capping machines have a single and poor fixing effect on the bottle caps when capping liquid-filled bottles. The most direct consequence is that the bottle caps are easy to loosen or fall off during transportation or storage. The loosening or falling of the bottle caps will cause the sealing inside the liquid-filled bottles to be destroyed. The existing fully automatic capping machines often lack an immediate and efficient sealing detection mechanism, resulting in additional time and equipment required for sealing detection after the capping is completed, thereby reducing the overall production efficiency. Due to the low detection efficiency, the problem of poor sealing is often unable to be discovered in the first time, resulting in unqualified products entering the market, damaging the reputation of the company and the interests of consumers.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an instant and intuitive sealing detection means by expanding the air bag and making it fit tightly against the outside of the liquid-filled bottle, so as to immediately judge whether the sealing between the bottle cap and the bottle mouth of the liquid-filled bottle is good. The instant detection method greatly improves the production efficiency and reduces the product waste and quality problems caused by poor sealing. The air bag can adapt to liquid-filled bottles of different sizes and shapes, further improving the applicability and accuracy of the detection. Then, gas is continuously introduced into the interior of the sealed shell through the air pipe interface, and the camera takes pictures of the liquid-filled bottle, and the sealing detection system automatically detects whether the bottle cap and the liquid-filled bottle are screwed on.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fully automatic capping machine for filling and packaging, comprising a filling fully automatic capping machine casing and a sealing detection system, a hydraulic press is installed on the inner surface of the filling fully automatic capping machine casing, an integral adjustment component is installed on the outer surface of the output end of the hydraulic press, two sealed shells are installed on the outer surface of the integral adjustment component, electric telescopic rods are installed inside the two sealed shells, guide tubes are provided on the two electric telescopic rods, first pistons are installed on one end surface of the two guide tubes, connecting rings are installed on the inner surfaces of the two sealed shells, suction cups are installed on the inner surfaces of the two connecting rings, sealing tubes are installed on the top surfaces of the two suction cups, the inner surface of the sealing tube is in active contact with the outer surface of the first piston, and synchronous sealing components are installed on the outer surfaces of the two guide tubes.
