Description

Technical Field

[0001] The present invention relates to the technical field of micro-crack detection devices, and more particularly to a micro-crack detection device based on a structure of jetting conductive liquid. Background Art

[0002] In the production of alcoholic beverages, it is necessary to detect whether there are cracks in glass wine bottles before filling. In modern industrial production, an airtight detector is used to seal and blow air into the glass wine bottles, and the air pressure is set within an appropriate range according to the thickness and shape of the glass wine bottles. The glass wine bottles with cracks will be blown up, while the glass is intact. At present, liquor production enterprises mainly manually place the glass wine bottles into the airtight detector and operate the airtight detector to detect the glass wine bottles. When the glass wine bottles with cracks are blown up, they will make a loud noise. Workers working in this environment for a long time will suffer hearing damage. At the same time, manual detection has high costs and low efficiency. All the detection methods that have emerged in the current similar research, including long-term static weighing, negative pressure detection, electronic nose (leakage ethanol concentration) detection, etc., cannot meet the requirements of fast, stable, and reliable detection in industrial fields. Summary of the Invention

[0003] The purpose of the present invention is to provide a micro-crack detection device based on a structure of jetting conductive liquid, which can solve the problems of high noise and low working efficiency, and detect the quality of the bottle body for the parts of micro-cracks on the bottle body that are invisible to the naked eye, such as ceramic bottles or glass bottles, ceramics and other strongly insulated or high-impedance containers.

[0004] The present invention provides a micro-crack detection device based on a structure of jetting conductive liquid, including a water spraying rod, a base, and an annular discharge structure. The base is used to place an empty bottle. The water spraying rod is arranged above the empty bottle. The annular discharge structure is arranged outside the empty bottle. The water spraying rod is limited by a fixing frame sleeved outside the water spraying rod. The base can move vertically up and down, and then the water spraying rod enters the inside of the empty bottle through the bottle mouth of the empty bottle. The water outlet end of the water spraying rod is provided with a nozzle, and the nozzle is used to evenly sprinkle the sprayed water on the inner wall of the empty bottle. The base and the annular discharge structure are respectively charged.

[0005] Preferably, the nozzle is provided with a water inlet and a water spraying port. The water spraying port is arranged on the side surface of the nozzle and is of an annular structure, and the annular structure can make the water flow evenly disperse around.

[0006] Preferably, the nozzle is a circular nozzle. The bottom end of the nozzle is provided with an adjusting piece having the same diameter as the nozzle body, and the gap between the adjusting piece and the nozzle body is the water spraying port.

[0007] Preferably, the adjusting piece is threadedly connected to the nozzle body, and the size of the gap is adjusted by rotating the adjusting piece to further adjust the water output.

[0008] Preferably, there are three water inlets.

[0009] Preferably, the annular discharge structure is fixedly connected to the water spray rod and is arranged at the lower part of the fixing frame.

[0010] Preferably, the water spray rod is slidably connected to the fixing frame, and the base is fixedly connected to the fixing frame through a connecting rod. When the base moves up and down, the fixing frame can be driven to move synchronously.

[0014] Beneficial effects:

[0015] The present invention detects the quality of the bottle body for parts of micro-cracks on the bottle body that are invisible to the naked eye on products such as ceramic bottles or glass bottles, which are strong insulation or high-impedance containers. A water film is basically completely covered on the inner wall of the container through a water spraying device, and a conductor high-voltage discharge is used outside the container to establish two electric fields with a potential difference inside and outside the container. By detecting the change of the electric field parameters, the detection of container sealing defects (pinholes, micro-cracks, etc.) or the warning of potential defects (unpenetrated cracks, etc.) is realized.

[0025] Embodiment 1

[0026] A microcrack detection device based on a structure for spraying conductive liquid, as Figures 1-4As shown in the figure (in this embodiment, water is defined as the conductive liquid for illustration), it includes a water spraying rod 1, a base 2, and an annular discharge structure 3. The base 2 is used to place an empty bottle 7. The water spraying rod 1 is arranged above the empty bottle 7, and the annular discharge structure 3 is arranged outside the empty bottle 7. The base 2 and the annular discharge structure 3 are respectively charged. The water spraying rod 1 is limited by a fixing frame 4 sleeved outside the water spraying rod 1. The base 2 can move vertically up and down. Then, the water spraying rod 1 enters the inside of the empty bottle 7 through the bottle mouth of the empty bottle 7. A nozzle 5 is provided at the water outlet end of the water spraying rod 1. The nozzle 5 is used to evenly sprinkle the sprayed water on the inner wall of the empty bottle 7. The nozzle 5 is provided with a water inlet 6 and a water spraying port 8. The water spraying port 8 is arranged on the side of the nozzle 5 and is in an annular structure. The annular structure can make the water flow evenly disperse around. The bottom end of the nozzle 5 is provided with an adjusting piece 9 with the same diameter as the nozzle body. The gap between the adjusting piece 9 and the nozzle body is the water spraying port 8. The adjusting piece 9 is threadedly connected to the nozzle body. By rotating the adjusting piece 9, the size of the gap is adjusted to adjust the water output. The annular discharge structure 3 is fixedly connected to the water spraying rod 1 and is arranged at the lower part of the fixing frame 4. The water spraying rod 1 is slidably connected to the fixing frame 4. The base 2 is fixedly connected to the fixing frame 4 through a connecting rod 12. When the base 2 moves up and down, it can drive the fixing frame 4 to move synchronously. The upper end of the water spraying rod 1 is provided with a water spraying rod base 10. The water spraying rod 1 is fixed to the water spraying rod base 10 through an annular ring 11. The middle part of the annular discharge structure 3 is provided with a space for accommodating the empty bottle. When the base 2 moves upward, the empty bottle 7 is clamped in the space to complete the fixation of the empty bottle 7. The annular discharge structure 3 is internally provided with a tip structure that can achieve tip discharge.

[0027] Working and using process:

[0028] Place the empty bottle 7 on the base 2. The empty bottle 7 can be made of various materials, including but not limited to glass, pottery, porcelain, plastic, wood, bamboo, etc. Packaging products such as liquids, powders, suspensions, and granules are all strongly insulating or high-impedance containers. Place the insulating container on the charged base 2 and there is an annular discharge structure 3 with tip discharge on the side. The water spraying rod 1 is fixed to the water spraying rod base 10 through an annular ring 11. The base 2 moves upward. After the water spraying rod 1 enters the inside of the bottle from the bottle mouth, it starts to spray water around the bottle, and then a water film is basically completely covered on the inner wall of the empty bottle. 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, the tip structure inside it can achieve tip discharge, causing the air near it to be ionized to generate gas discharge. The air directly contacts the bottle body, so that there is an electric field around the bottle body. Water can be a conductor. If the glass bottle has micro-cracks or defects, the water will enter the fine cracks as a conductor, and thus breakdown current will be generated due to the flow of charges. According to the detected current value, the size of the pinholes or micro-cracks is judged to complete the entire detection process.

[0029] Therefore, this device targets strong insulating or high-impedance containers such as glass and ceramics. Under normal circumstances where the container is sealed properly, no breakdown current will be generated due to the charge flow inside and outside the container. However, when there are discharge channels such as pinholes or microcracks in the container, breakdown current will be generated due to the charge flow. According to the detected current value, the size of the pinhole or microcrack is judged to complete the entire detection process. Since the order of magnitude of electrons is very small, an overall product designed using the water spraying structure and the principle of point discharge is adopted. Moreover, the detection voltage can be adjusted according to the specific situation of the object to be detected (such as material, density, etc.) to achieve the purpose of accurately distinguishing qualified products from unqualified products.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
