[0036] Please refer to the following: Figures 1 to 3 The present invention provides a device for detecting air leakage in filled beverages. The device includes a conveying assembly and a detection assembly. The conveying assembly includes a conveying mechanism and two barriers, which are respectively located on both sides of the conveying mechanism. The conveying mechanism is used to convey the filled beverage. The detection assembly is connected to the barriers and is used to detect whether the beverage is leaking air. The detection assembly includes a first drive assembly 21, a rotating wheel 22, an annular airbag 23, and a pressure detection assembly 24. The first drive assembly 21 is connected to the barriers. The rotating wheel 22 is horizontally arranged, with its center connected to the power output end of the first drive assembly 21, and is adapted to rotate under the drive of the first drive assembly 21. The annular airbag 23 is sleeved on the outer circumference of the rotating wheel 22 and connected to it. It is suitable for being filled with gas at a preset pressure, and the annular airbag 23 protrudes radially outward from the inner side of the barriers, pressing against the beverage. The pressure detection assembly 24 is connected to the rotating wheel 22 and communicates with the annular airbag 23, and is used to detect the pressure inside the annular airbag 23.
[0037] It should be noted that when a beverage leaks air, the pressure inside the bottle decreases, which in turn reduces the pressure on the annular air bladder 23, resulting in a smaller pressure change inside the annular air bladder 23. When there is no leak, the pressure on the annular air bladder 23 from the bottle body is greater, resulting in a larger pressure change inside the annular air bladder 23. Therefore, by detecting the magnitude of the pressure change inside the annular air bladder 23 using a pressure sensor, it is possible to detect whether the beverage is leaking air.
[0038] Specifically, the pressure detection component 24 uses an existing wireless pressure sensor with a built-in power supply; the first drive component 21 is an existing drive motor. The linear velocity at the radial edge of the annular airbag 23 is consistent with the movement speed of the beverage bottle.
[0039] The beneficial effects of the leak detection device for filled beverages provided by this utility model are as follows: Compared with the prior art, the leak detection device for filled beverages provided by this utility model, during operation, the conveying mechanism conveys the beverage forward, and at the same time, the first driving component 21 drives the rotating wheel 22 to rotate the annular airbag 23. When the beverage passes by, the annular airbag 23 squeezes the bottle body of the beverage. The pressure detection component 24 detects the change in pressure inside the annular airbag 23, thereby detecting whether the beverage is leaking. During the operation, only the annular airbag 23 is in contact with the bottle body, and the contact between the annular airbag 23 and the bottle body is elastic, which is not easy to damage the bottle body. Moreover, the rotation of the annular airbag 23 under the drive of the first driving component 21 can make the friction between the annular airbag 23 and the bottle body static friction, further reducing the possibility of damage to the bottle body.
[0040] like Figure 1 and Figure 2 As shown, in a specific embodiment of the leakage detection device for filled beverages provided in this utility model, the enclosure includes a baffle 13 and a top plate 14. The baffle 13 is arranged vertically, and the top plate 14 is arranged horizontally. One side is connected to the top of the baffle 13, and the other side extends away from the conveying mechanism.
[0041] like Figure 1 and Figure 2 As shown, in a specific embodiment of the leak detection device for filled beverages provided in this utility model, the conveying mechanism includes a conveyor belt 11 and a second drive assembly 12. The conveyor belt 11 is disposed between two baffles 13, the second drive assembly 12 is connected to the baffles 13, and the power output end is connected to the conveyor belt 11 to drive the conveyor belt 11 to move.
[0042] Specifically, the conveying mechanism is a traditional belt conveyor, and the conveyor belt 11 and the second drive assembly 12 are both existing belt conveyors, including the conveyor belt 11 and the drive motor.
[0043] like Figure 1 and Figure 2 As shown, in a specific embodiment of the leakage detection device for filled beverages provided in this utility model, the rotating wheel 22 has an annular groove around its circumference, and the annular airbag 23 is embedded in the annular groove to restrict the annular airbag 23 within the annular groove and prevent the annular airbag 23 from falling off.
[0044] In one specific embodiment of the leakage detection device for filled beverages provided in this utility model, the annular airbag 23 is provided with anti-slip stripes to increase the friction between the annular airbag 23 and the beverage bottle, prevent relative sliding between the annular airbag 23 and the bottle, and reduce the possibility of damage to the bottle.
[0045] like Figure 1 and Figure 2 As shown in the embodiment of the present invention, in a specific implementation of the leak detection device for filled beverages, the detection component further includes an adjustment component. The adjustment component is connected to the top plate 14 and to the first drive component 21, and is used to adjust the distance of the annular airbag 23 protruding from the inner side of the baffle 13, so as to increase the versatility of the device and adapt to more types and specifications of beverages.
[0046] Specifically, such as Figure 2 and Figure 3 As shown in the embodiment of the leakage detection device for filled beverages provided in this utility model, the adjustment component includes a support rod 31, a guide rod 32, and a third drive component. A guide hole perpendicular to the conveying direction of the conveying mechanism is provided in the top plate 14, and a groove communicating with the guide hole is provided at the top of the guide hole. The upper end of the support rod 31 is connected to the first drive component 21, and the lower end passes through the groove and is connected to the guide rod 32. The support rod 31 is slidably engaged with the groove. The guide rod 32 is disposed in the groove and is slidably engaged with the guide hole. The third drive component is connected to the top plate 14, and the power output end is connected to the guide rod 32 to drive the guide rod 32 to slide back and forth in the guide hole.
[0047] Furthermore, such as Figure 2 and Figure 3 As shown, in a specific embodiment of the leak detection device for filled beverages provided in this utility model, the third driving component is a screw 33. The screw 33 is coaxially arranged with the guide rod 32 and threadedly engaged with the top plate 14. One end of the screw 33 protrudes from the top plate 14, and the other end passes through the top plate 14 and extends into the guide hole to rotate and engage with one end of the guide rod 32.
[0048] It should be understood that turning the screw 33 will drive the guide rod 32 to slide in the guide hole, thereby driving the wheel 22 and the annular airbag 23 to move in a direction perpendicular to the conveying direction, adjusting the distance of the annular airbag 23 protruding from the baffle 13 to accommodate beverages with bottles of different diameters.
[0049] like Figure 1 and Figure 2As shown in the embodiment of the present invention, in a specific implementation of the leak detection device for bottled beverages, there are two detection components. The two detection components are symmetrically arranged on two barriers and connected to the two barriers respectively to ensure that the force on both sides of the bottle is uniform and to prevent the beverage from tipping over.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
