Description

Technical Field

[0001] The utility model relates to the technical field of bottled beverage leakage detection, in particular to an online leakage detection device for bottled beverages. Background Art

[0002] The existing bottle leak detection method is that the leak detection head moves downward under the drive of the cylinder and is stably squeezed at the bottle mouth. The leak detection head and the bottle mouth are in a sealed state, and air is injected inward. Whether the bottle is leaking is determined by whether the air pressure changes;

[0003] For example, the existing patent, application number 201720070674.8, a bottle leak detector, includes a frame, a leak detection device arranged on the frame, the leak detection device includes a plurality of leak detection cylinders, a flange seat arranged on the leak detection cylinder, and a rotatable gas nozzle head installed on the flange seat through an elastic connection component, the elastic connection component includes a screw for connecting the flange seat and the gas nozzle head, a nut arranged on the screw and abutting against the gas nozzle head, a compression spring arranged on the screw between the flange seat and the gas nozzle head, and a ball arranged between the flange seat and the gas nozzle head. The utility model is provided with a multi-station leak detection device, which can perform leak detection tests on multiple bottles at the same time. The gas nozzle head of the leak detection device can rotate according to the shape of the bottle mouth, and the inflation port of the gas nozzle head is concave, and a sealing pad is arranged at the inflation port. The gas nozzle head is pressed down onto the bottle to achieve the effect of fitting the shape of the bottle mouth and maintaining the airtightness of the bottle, and then the bottle is inflated and tested;

[0004] When testing for leaks in bottles, it is necessary to ensure that the bottles are stably located under the leak detection head, and that the leak detection head stably covers the bottle mouth when the leak detection head moves downward. However, in actual use, the bottles may be misplaced due to air flow, vibration or other external reasons. At this time, when the leak detection head moves downward, it may be misplaced with the bottle mouth. In the worst case, the bottle may not be able to detect leaks normally and the leak detection data may be inaccurate. In the worst case, the bottle may fall over, triggering a domino effect and making it impossible to carry out subsequent work. Therefore, an online leak detection device for bottled beverages is proposed to address the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an on-line leak detection device for bottled beverages to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0011] The existing bottle leak detection method is that the leak detection head moves downward under the drive of the cylinder and stably squeezes the bottle mouth.

When the bottle is leaking, it is necessary to ensure that the bottle is stably located under the leak detection head, and the leak detection head is ensured to stably cover the bottle mouth when the leak detection head moves downward. However, in actual use, the bottle may be misplaced due to air flow, equipment vibration or other external reasons. At this time, when the leak detection head moves downward, it may be misplaced with the bottle mouth, which may cause normal leak detection at the least, inaccurate leak detection data, or even worse, the leak detection head may be misplaced with the bottle mouth.

[0013] When the lower pressure plate is located at the mouth of the bottle, the inflation device fills the gas into the air pipe and discharges it into the bottle. The pressure gauge of the inflation device is used for detection. Once the pressure value becomes smaller, it means that the bottle is leaking and needs to be removed later.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Example 1

[0038] See also Figure 1 , Figure 2 and Figure 3 , the utility model provides a technical solution:

[0039] An online leak detection device for bottled beverages, comprising a transport rack 1 and a leak detection device 2.

[0040] A transport rack 1 for transporting bottles is provided at the front side of the leak detection device 2;

[0041] A leak detection assembly 5 and an inflatable device 6 are installed inside the leak detection device 2. The leak detection assembly 5 includes a second hydraulic rod 501, a movable plate 502 and a leak detection cylinder 503. The top of the second hydraulic rod 501 is fixedly connected to the leak detection device 2. The bottom of the second hydraulic rod 501 is fixedly connected to the movable plate 502. The bottom center of the movable plate 502 is fixedly connected to the leak detection cylinder 503. The bottom of the leak detection cylinder 503 is fixedly connected to a hollow tube 504. The bottom of the hollow tube 504 is fixedly connected to a lower pressure plate 505.

[0042] The bottom sides of the movable plate 502 are fixedly connected with vertically arranged movable components 510, and the bottom of the movable component 510 is fixedly connected with an extrusion plate 511, the bottom of the extrusion plate 511 is fixedly connected with a protective cover 506, and the inside of the protective cover 506 is fixedly connected with a guide cover 507.

[0043] The existing bottle leak detection method is that the leak detection head moves downward under the drive of the cylinder and stably squeezes the bottle mouth. The leak detection head and the bottle mouth are in a sealed state, and air is injected inward. Whether the air pressure changes is used to determine whether the bottle is leaking. When the bottle is leaking, it is necessary to ensure that the bottle is stably located under the leak detection head, and ensure that the leak detection head stably covers the bottle mouth when the leak detection head moves downward. However, in actual use, the bottle may be misplaced due to air flow, equipment vibration or other external reasons. At this time, when the leak detection head moves downward, it may be misplaced with the bottle mouth. At the least, normal leak detection cannot be performed, and the leak detection data is inaccurate. At worst, the bottle may tip over, which will cause a domino effect. The domino effect makes it impossible to carry out subsequent work. When the device is used, an external power supply is connected, and its moving component 510 drives the extrusion plate 511 to move in advance, and the extrusion plate 511 can drive the protective cover 506 to move downward, and a guide cover 507 is arranged inside the protective cover 506, which can ensure that it is stably sleeved on the outside of the bottle. The inside of the guide cover 507 is inclined to guide the bottle to ensure that the bottle is stably located inside the protective cover 506. Then the leak detection cylinder 503 drives the hollow tube 504 and the lower pressure plate 505 to move, and the lower pressure plate 505 can be stably located at the bottle mouth for subsequent leak detection. This setting can ensure accurate leak detection of the bottle by pre-fixing the bottle.

[0044] In this embodiment, the lower pressure plate 505 and the protective cover 506 are alternately moved up and down to limit the position of the bottle, thereby preventing it from tipping over and misaligning to affect the leak detection. The bottom opening diameter of the guide cover 507 gradually decreases upward, and is used to guide the bottle to ensure that the bottle does not tip over during leak detection. During the leak detection, the protective cover 506 is first dropped to protect the bottle, and then the lower pressure plate 505 squeezes the bottle mouth. After the leak detection is completed, the protective cover 506 is moved up in advance, and then the lower pressure plate 505 is separated from the bottle mouth.

[0045] Example 2

[0046] This embodiment is an improvement on embodiment 1. Figure 3 Specifically, an air pipe 512 is disposed inside the hollow tube 504 , the other end of the air pipe 512 is connected to the inflation device 6 , and the other end of the air pipe 512 passes through the upper and lower end surfaces of the lower pressure plate 505 .

[0047] When the lower pressure plate 505 is located at the bottle mouth of the bottle, its inflation device 6 fills its gas into the air pipe 512 and discharges it into the bottle, and detects it through the pressure gauge of the inflation device 6. Once the pressure value becomes smaller, it means that the bottle is leaking and needs to be removed later. The air pipe 512 is made of rubber material, which can be bent and moved, thereby ensuring that the air pipe 512 can move smoothly when the lower pressure plate 505 moves. A certain length of the air pipe 512 between the lower pressure plate 505 and the limit block 509 is reserved, which can ensure that the lower pressure plate 505 can move smoothly.

[0048] Example 3

[0049] This embodiment is an improvement on embodiment 2. Figure 1 Specifically, a first hydraulic rod 3 fixedly connected to the leak detection device 2 is arranged on the rear side of the transport frame 1, and the first hydraulic rod 3 is arranged longitudinally, and a rejecting plate 4 is fixedly connected to the movable end of the first hydraulic rod 3.

[0050] A controller is built into the device. When it determines that a bottle is leaking, the first hydraulic rod 3 is arranged longitudinally. By controlling the first hydraulic rod 3 to drive the rejection plate 4 to move forward, the bottle can be pushed to the defective product area through the rejection plate 4 for centralized collection. The rejection plate 4 is located at the central height of the bottle. At this time, the bottle can be stably pushed to the defective product area to prevent the bottle from tipping over in the transport area of ​​the transport rack 1.

[0051] Example 4

[0052] This embodiment is an improvement on embodiment 3. Figure 4 Specifically, the moving component 510 includes a fixed frame 5101 and a motor 5102. The top of the fixed frame 5101 is fixedly connected to the moving plate 502. The inside of the fixed frame 5101 is fixedly connected to the motor 5102. The main shaft end of the motor 5102 is fixedly connected to the threaded shaft 5103. The outer side of the threaded shaft 5103 is spirally connected to the moving sleeve 5104. The bottom of the moving sleeve 5104 is fixedly connected to the extrusion plate 511.

[0053] The lower part of the inner wall of the guide cover 507 is provided with an inclined surface.

[0054] After the leak detection is completed, the motor 5102 is reversed to drive the threaded shaft 5103 to rotate, thereby driving the moving sleeve 5104 to move upward, ensuring that the protective cover 506 and the guide cover 507 are stably moved upward from the outside of the bottle, and then the leak detection cylinder 503 is reset, and the lower pressure plate 505 is separated from the bottle, so that the bottle can stand stably;

[0055] In this embodiment, the motors 5102 on both sides are synchronous motors, which are used to ensure that the extrusion plate 511 moves up and down stably. Since the extrusion plate 511 is stably connected to the protective cover 507, the movable sleeve 5104 can only move up and down and cannot rotate by itself.

[0056] Example 5

[0057] This embodiment is an improvement on embodiment 4. Figure 3 Specifically, a vertically arranged guide cylinder 508 is fixedly connected to the top of the protective cover 506 , and a hollow tube 504 is arranged inside the guide cylinder 508 .

[0058] The upper inner wall of the guide cover 507 is fixedly connected to the limiting block 509 , and an air pipe 512 is arranged inside the limiting block 509 on one side.

[0059] The setting of the limit block 509 can ensure that the lower pressing plate 505 is stable inside the guide cover 507, avoiding the situation that the lower pressing plate 505 and the guide cover 507 are separated. The setting of the guide cylinder 508 ensures that the hollow tube 504 can move up and down stably, so as to achieve the purpose of guidance.

[0060] In this embodiment, an air pipe 512 is provided inside the hollow tube 504, and the air pipe 512 is located in the center of the lower pressure plate 505, and is used to stably inflate the interior of the bottle. There are two limit blocks 509, which can stably prevent the lower pressure plate 505 from moving upward excessively.

[0061] Example 6

[0062] This embodiment is an improvement on embodiment 5. Figure 5 Specifically, a sealing gasket 513 is fixedly connected to the bottom of the lower pressing plate 505, and the sealing gasket 513 is made of rubber block material.

[0063] A sealing pad 513 is provided at the bottom of the lower pressing plate 505, which can ensure that the sealing pad 513 covers the bottle mouth to ensure sealing, thereby ensuring the accuracy of the leak detection data of the bottle;

[0064] In this embodiment, when the sealing gasket 513 is in close contact with the mouth of the bottle, the sealing gasket 513 collapses slightly, and the bottom of the sealing gasket 513 can be embedded in the outside of the mouth of the bottle to ensure sealing and avoid air leakage.
