Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of the production of bottle caps, and particularly relates to a leak detection device for liquor bottle caps. Background Technique
[0002] As the old saying goes, "A feast without wine is not a feast." At banquets, dinners and other feasts, liquor is generally considered an indispensable part. In recent years, with the continuous development of society and the continuous progress of science and technology, high-end liquor has received more and more attention and recognition from people. Generally, delicate wine bottles are used for packaging. The bottle cap is an important component for sealing the bottle, and the sealing performance is one of the key performances of the bottle cap. Especially for liquor bottle caps, the alcohol contained in liquor is a volatile substance. If there is no good sealing performance, the alcohol is very easy to volatilize, which will seriously affect the quality of liquor. In addition, good sealing performance can also prevent external air and impurities from eroding the liquor, and maintain the taste and quality of the product.
[0003] At present, the sealing performance of bottle caps is usually detected by means of air pressure. After the bottle cap is closed, gas is introduced, and then whether there is air leakage is felt by hand to judge whether there is a leak hole in the bottle cap. The detection can only be carried out one by one independently, so the detection efficiency is low. Moreover, some leak holes are relatively small, the leaked gas is less and the leakage speed is slow, and the feeling by hand is not obvious, resulting in inaccurate detection. Summary of the Utility Model
[0004] The utility model aims to provide a leak detection device for liquor bottle caps to solve the problems of low detection efficiency in the existing technology when detecting one by one and low detection accuracy when the air leakage is not obvious.
[0005] The leak detection device for liquor bottle caps in this scheme includes a central control platform, a blowing mechanism and a mounting plate. A plurality of hollow tubular air nozzles are evenly distributed on the mounting plate. The air nozzles are numbered respectively. An air outlet communicated with the inside is arranged at the top of the air nozzle. A pressure sensor is arranged on the air nozzle. The lower ends of the plurality of air nozzles all pass through the mounting plate and are communicated with the blowing mechanism through hoses. A sealing gasket for abutting against the opening end of the bottle cap is arranged on the air nozzle. A bottle cap pressing plate is arranged above the mounting plate, and the bottle cap pressing plate is connected with a cylinder for driving it to move up and down;
[0006] The central control platform includes a controller and a display. Warning lights corresponding to the air nozzles one by one are arranged on the display. The pressure sensor transmits the detected pressure data to the controller through a signal. A qualified product pressure value is preset in the controller. When the detected pressure is lower than the pressure value, the corresponding warning light will give an alarm.
[0007] The working principle of this solution is: place the bottle cap to be tested on the top of the air nozzle on the mounting plate, apply pressure to the bottle cap through the bottle cap pressure plate, so that the opening edge of the bottle cap is in close contact with the sealing gasket, and the sealing gasket and the bottle cap form a sealed space. After the air nozzle is ventilated, it blows into the sealed space, and the internal pressure of the sealed space increases. After a few seconds, the pressure sensor detects the pressure. When the detected pressure is lower than the preset pressure value in the controller, the warning light corresponding to the corresponding air nozzle will sound an alarm, indicating that there is a leak in the bottle cap on the air nozzle with that number, indicating that the sealing of the bottle cap does not meet the requirements.
[0008] The beneficial technical effect of this solution is that it can detect leaks on multiple bottle caps at the same time, and uses a bottle cap pressure plate to apply pressure to all the bottle caps on the mounting plate at the same time, so that they fit firmly with the sealing gasket to form a sealed space. At the same time, after blowing and pressurizing for several seconds (usually 2 to 3 seconds), it can be detected whether there are leaking bottle caps. Compared with judging by feel one by one, this solution significantly improves the detection efficiency and accuracy.
[0009] Furthermore, the air nozzle is externally sheathed with a spring, the top of which is connected to a sealing gasket, which is in sliding connection with the air nozzle. When the bottle cap pressure plate presses down on the bottle cap, the spring provides a certain buffering effect. At the same time, the compressed spring exerts a reverse force, causing the sealing gasket and bottle cap to be compressed in both directions, thus enhancing the fit between the two and preventing leakage due to poor contact between the two, thereby further improving detection precision.
[0010] Furthermore, the upper surface of the sealing gasket is provided with a sealing groove for the edge of the bottle cap opening to be inserted into.
[0011] Furthermore, the mounting plate is externally sheathed with a support shell, the top of which is provided with cap placement holes corresponding to the gas nozzles. The support shell acts as a protective barrier, reducing the probability of airborne dust falling onto the gas nozzles, thereby preventing unnecessary contamination of the bottle caps during leak detection.
[0012] Furthermore, a lifting push rod is connected to the bottom of the mounting plate. In the case of a support shell, when the bottle cap is placed at the cap placement hole, for some shallow bottle caps, the opening edge may not be able to contact the sealing gasket. In this case, by raising the mounting plate, the sealing gasket is raised to fit more tightly with the edge of the bottle cap. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The reference numerals in the accompanying drawings of the specification include: mounting plate 1, spring 2, air nozzle 3, sealing gasket 4, hose 5, lifting push rod 6, air outlet 7, bottle cap pressing plate 8, cylinder 9.
[0019] The embodiment is basically as shown in the accompanying... Figures 1 to 3 : The leak detection device for liquor bottle caps includes a central control platform, a blowing mechanism, and a mounting plate 1. A lifting push rod 6 is connected below the mounting plate 1. There are two rows of a total of 8 hollow tubular air nozzles 3 evenly distributed on the upper surface of the mounting plate 1. The air nozzles 3 are numbered respectively. An air outlet 7 communicating with its interior is provided at the top of the air nozzle 3. A pressure sensor is provided on the air nozzle 3. The lower ends of the plurality of air nozzles 3 all pass through the mounting plate 1 and are communicated with the blowing mechanism through a hose 5. A sealing gasket 4 for abutting against the open end of the bottle cap is provided on the air nozzle 3. The sealing gasket 4 is made of a hard material. A sealing groove for the open edge of the bottle cap to be inserted into is provided on the upper surface of the sealing gasket 4. A spring 2 is sleeved outside the air nozzle 3. The top of the spring 2 is connected to the sealing gasket 4. The sealing gasket 4 is slidably connected to the air nozzle 3. A bottle cap pressing plate 8 is provided above the mounting plate 1. There is a bottle cap pressing plate 8 respectively above the two rows of air nozzles 3. The bottle cap pressing plate 8 is connected with a cylinder 9 that drives it to move up and down; the central control platform includes a controller and a display. Warning lights corresponding to the air nozzles 3 are provided on the display. The numbers of the air nozzles 3 correspond to the numbers of the pressure sensors and the warning lights. The pressure sensor transmits the detected pressure data to the controller through a signal. A qualified product pressure value is preset in the controller. When the detected pressure is lower than the pressure value, the corresponding warning light will give an alarm.
[0020] The specific implementation process is as follows: Place the bottle cap to be detected at the cap placement hole above the air nozzle 3 on the mounting plate 1. Apply pressure to the bottle cap through the bottle cap pressing plate 8. The lifting push rod 6 below the mounting plate 1 also raises the mounting plate 1. The open edge of the bottle cap is in close contact with the sealing gasket 4. The spring 2 outside the air nozzle 3 is appropriately compressed. The sealing gasket 4 and the bottle cap form a sealed space. After the air nozzle 3 is ventilated, air is blown into the sealed space. The pressure inside the sealed space increases. After 2 - 3 seconds, the pressure sensor detects the pressure magnitude. When the detected pressure is lower than the preset pressure value in the controller, the warning light corresponding to the corresponding air nozzle 3 will give an alarm, indicating that there is a leakage in the bottle cap on the air nozzle 3 with this number, indicating that the sealing performance of the bottle cap cannot meet the requirements, so as to quickly select the leaking bottle caps from multiple bottle caps. For example Figure 4In it, if the pressure data detected by the 1# pressure sensor is lower than the preset value in the controller, the 1# warning light will turn on. When it is not lower than the preset value, the 1# warning light will not turn on.
