[0002] The bottle cap is an important part of food and beverage packaging and is also the place where consumers first come into contact with the product. The bottle cap has the function of keeping the product in the container airtight, so it is widely used in bottled products. The bottle cap will be subjected to corresponding tests when leaving the factory to ensure its sealing performance. However, the existing detection fixtures can only test the sealing performance of the bottle cap or the bottle mouth alone, and cannot determine whether the bottle cap and the bottle mouth have the same sealing performance after being matched. In addition, the existing fixtures can only test single-type bottle caps and are not applicable to bottle caps of different specifications and sizes, resulting in poor applicability. This greatly increases the testing cost and causes certain waste of resources. Content of the Utility Model

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment

[0019] Please refer toFigures 1-5 , the present utility model provides the following technical solutions: A bottle cap sealing detection fixture, including a cylinder 1 and a fixed rod 6. The upper end surface of the cylinder 1 is movably installed with a cylinder connection end 15. The cylinder connection end 15 is movably installed with a fixing bolt 9 through a thread. An air inlet 8 is arranged on the outer surface of the fixing bolt 9. A rubber pad 5 is fixedly installed on the upper end surface of the fixing bolt 9. An expanding rubber plug 12 is fixedly installed on the lower end surface of the rubber pad 5. A chuck 4 is fixedly installed on the lower end surface of the expanding rubber plug 12. The fixing bolt 9 is movably installed through between the expanding rubber plug 12 and the chuck 4. The fixing bolt 9 is hollow, and an air outlet hole is arranged in the middle of the upper end surface of the rubber pad 5.

[0020] In this implementation scheme, the cylinder 1 provides motion support for the cylinder connection end 15. The cylinder connection end 15 can cooperate with the cylinder 1 to realize the up and down motion of the fixing bolt 9. The air inlet 8 provides a channel for air pressure to enter the fixing bolt 9. When the fixing bolt 9 moves downward, the rubber pad 5 moves due to the movement of the fixing bolt 9. Thus, the chuck 4 provides a blocking effect for the expanding rubber plug 12, and then the expanding rubber plug 12 expands. Thus, a sealed space is formed between the expanding rubber plug 12 and the bottle cap. The air outlet hole on the rubber pad 5 can convey the air pressure entering the inside of the fixing bolt 9 from the air inlet 8 to the sealed space formed between the bottle cap and the expanding rubber plug 12, so as to detect the sealing performance and pressure resistance of the bottle cap.

[0021] Specifically, support columns 2 are respectively fixedly installed at the four corners of the upper end surface of the cylinder 1. A fixing plate 3 is fixedly installed on the upper end surface of the support column 2. A slot hole is arranged on the upper end surface of the fixing plate 3. A chuck 4 is movably installed on the upper end surface of the fixing plate 3. A long rod 14 is fixedly installed on the upper end surface of the fixing plate 3. A fixing frame 13 is fixedly installed on the upper end surface of the long rod 14.

[0022] In this embodiment, the cylinder 1 provides support for the support column 2, the support column 2 provides support for the fixing plate 3, and the slot hole on the fixing plate 3 facilitates the installation of the chuck 4. Thus, the fixing plate 3 provides support and limit functions for the chuck 4. The fixing plate 3 provides a support function for the long rod 14, and the long rod 14 provides a support function for the fixing frame 13.

[0023] Specifically, the fixed rod 6 is movably installed on the fixing frame 13 through a thread. The fixed rod 6 is installed through the fixing frame 13. A top plate 7 is fixedly installed on the lower end surface of the fixed rod 6.

[0024] In this embodiment, the fixing frame 13 provides support and direction guidance for the movement of the fixed rod 6. The fixed rod 6 provides force support for the top plate 7 through thread cooperation with the fixing frame 13 to ensure that the bottle cap is fixed in place.

[0025] Specifically, an air inlet of the cylinder 10 and an air outlet of the cylinder 11 are arranged on the outer surface of the cylinder 1.

[0026] In this embodiment, the air inlet 10 and the air outlet 11 of the cylinder provide power support for the movement of the cylinder 1.

[0027] The working principle and usage process of the present utility model are as follows: First, the staff connects the pipelines of the air pump to the air inlet 10 and the air outlet 11 of the cylinder respectively. The cylinder 1 rises and drives the cylinder connection end 15 to move upward. Then, the staff installs the chuck 4 in place along the slot hole on the fixed plate 3, and then connects the lower end of the fixing bolt 9 to the cylinder connection end 15. Then, one path of the air pump is connected to the air inlet 8. The staff fits the bottle cap with the bottle mouth and then places it on the rubber pad 5. Then, the fixed rod 6 is rotated, and the top plate 7 is used to firmly fix the bottle cap. After the fixing is completed, the cylinder 1 drives the cylinder connection end 15 to move downward. When the cylinder connection end 15 moves downward, it will drive the fixing bolt 9 to move downward. Thus, the rubber pad 5 will also move downward. Therefore, due to the downward movement of the rubber pad 5, the expansion rubber plug 12 is pressed downward. The chuck 4 cooperates with the fixed plate 3 to block the expansion rubber plug 12. Thus, the expansion rubber plug 12 expands, and a sealed closed space is formed in cooperation with the bottle cap and the bottle mouth. After the work is completed, the device is placed in water, the air path entering the air inlet 8 is opened, and it is observed whether there is air leakage. The staff can continuously pressurize to observe the pressure resistance of the bottle cap. Due to the sealed space formed by the expansion of the expansion rubber plug 12, the staff can replace different bottle caps or bottle mouths to test the stability of the test data. Thus, the accuracy of the test data is greatly improved, and the work efficiency is further improved.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
