In wine production, it is necessary to detect whether there are cracks in the glass wine bottle before filling. In modern industrial production, the glass wine bottle is sealed and blown by an air-tight detector. The air pressure depends on the thickness and shape of the glass wine bottle.

The ring-shaped discharge structure 3 is fixedly connected with the water spray rod 1 and is arranged at the lower part of the fixed frame 4. The water spray rod 1 is slidably connected with the fixed frame 4, and the base 2 is fixedly connected with the fixed frame 4 through the connecting rod 12. When the base 2 moves up and down It can drive the fixed frame 4 to move synchronously.

Working and using process:

Place the empty bottle 7 on the base 2, including but not limited to glass, pottery, porcelain, plastic, wood, bamboo, etc., which are widely used in the packaging of liquids, powders, suspensions, granules and other products, all of which are strong insulation or high impedance container. Place the insulated container on the charged base 2 and there is an annular discharge structure 3 with pointed discharge on the side, the water spray rod 1 is fixed on the water spray rod base 10 by the annular ring 11, the base 2 moves upward, and the water spray rod 1 is released from the bottle After the mouth enters the inside of the bottle, it starts to spray water around the bottle, and then basically covers the inner wall of the empty bottle with a layer of water film. The base 2 and the annular discharge structure 3 are respectively charged. The base 2 directly contacts the bottom of the bottle. Although the annular discharge structure does not directly contact, its internal tip structure can realize tip discharge, causing the air near it to be ionized to generate gas discharge. The air directly Touch the bottle body, so that there is an electric field around the bottle body. Water can be used as a conductor. If the glass bottle is a defective product with micro-cracks, water will enter the tiny cracks as a conductor, which will cause a breakdown current due to the flow of charge. According to the detected current value, determine the pinhole or micro-crack. Size, to complete the entire detection process.

Therefore, this device is aimed at strong insulation or high impedance containers such as glass and ceramics. When the container is normally sealed, it will not generate any breakdown current due to the flow of charges inside and outside the container; but when the container has pinholes, micro cracks, etc. When channeling, a breakdown current will be generated due to the flow of charge. According to the detected current value, the size of the pinhole or micro-crack can be judged to complete the entire detection process. Because the order of magnitude of electrons is very small, the overall product is designed using the water spray structure and cutting-edge discharge principle, and the detection voltage can be adjusted according to the specific conditions of the detected object (such as material, density, etc.), so as to achieve high precision to distinguish qualified products from unqualified products the goal of.
