Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to a bottle cap airtightness testing device. Background Technology

[0002] Bottle caps are used to seal bottles. Depending on their function, bottle caps come in different shapes and have different operating methods. Some bottle caps require airtightness testing during production to ensure a proper seal and prevent spoilage of the contents. Currently, factories can automate bottle cap airtightness testing by transporting the caps to the testing position and using testing equipment. However, this method requires the caps to stop on the conveyor belt during testing, and only after the first cap is tested can the next one be transported, resulting in low testing efficiency and impacting overall bottle cap production efficiency. Summary of the Invention

Detailed Implementation

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0027] First, combine Figures 1-5 This invention describes a bottle cap airtightness testing device according to an embodiment of the present invention, used for testing the airtightness of bottle caps.

[0028] like Figures 1-5 As shown, an embodiment of the present invention provides a bottle cap airtightness detection device, comprising: a positioning component 1, a pressure head component 2, a detection component 3, and a cam 4.

[0029] The positioning component 1 is used to position the bottle cap, and the positioning component 1 rotates synchronously with the detection component 3;

[0030] The pressure head assembly 2 includes: a rotating disk 21, a probe mechanism 22, and a cam bearing 23;

[0031] The rotating disk 21 rotates synchronously with the positioning component 1. The probe mechanism 22 is mounted on the rotating disk 21 and can slide vertically on the rotating disk 21. The probe mechanism 22 is positioned corresponding to the bottle cap on the positioning component 1. One end of the probe mechanism 22 is connected to the cam bearing 23. The cam 4 has a guide rail 41. During the movement of the cam bearing 23 on the guide rail 41, the probe mechanism 22 slides vertically on the rotating disk 21. When the probe mechanism 22 moves to the bottom, it covers the bottle cap. The detection component 3 performs airtightness detection on the bottle cap.

[0032] This application achieves this by synchronously rotating the positioning component 1 and the rotating disk 21, ensuring that the probe mechanism 22 remains above the bottle cap. The cam bearing 23 moves vertically on the rotating disk 21 by moving on the guide rail 41, allowing the probe mechanism 22 to cover the bottle cap. This facilitates the detection component 3 in detecting the airtightness of the bottle cap through the probe mechanism 22. Throughout the process, the positioning component 1, the rotating disk 21, and the detection component 3 maintain synchronous rotation, enabling simultaneous airtightness detection of multiple bottle caps and improving the efficiency of bottle cap detection.

[0033] like Figure 2 and Figure 5 As shown, the positioning component 1 includes: a positioning disk 11 and a material holder 12;

[0034] The positioning disk 11 has multiple material seats 12 arranged in a circular and equal manner. Each material seat 12 has an air hole and is used to position the bottle cap.

[0035] The positioning plate 11 can be driven to rotate by a motor. The material seat 12 has air holes. If the airtightness of the bottle cap is insufficient, gas can escape through the air holes, so that the detection component 3 can detect the airtightness problem of the bottle cap.

[0036] like Figures 3-5 As shown, the probe mechanism 22 includes: a sealing head 24, a sliding block 25, a connecting cylinder 26, a sealing spring 27, and a connecting rod 28;

[0037] The connecting rod 28 is slidably connected to the rotating disk 21. One end of the connecting rod 28 is connected to the cam bearing 23, and the other end is connected to the connecting cylinder 26. The sliding block 25 is slidably disposed inside the connecting cylinder 26. The sealing spring 27 is disposed inside the connecting cylinder 26. One end of the sealing spring 27 is connected to the inner wall of the connecting cylinder 26, and the other end is connected to the sliding block 25. The portion of the sliding block 25 extending out of the connecting cylinder 26 is connected to the sealing head 24, which is used to cover the bottle cap. The bottom of the sealing head 24 has an annular groove, and a sealing layer 29 is fixed in the groove.

[0038] As the cam bearing 23 moves along the guide rail 41, it drives the sealing head 24 to move vertically via the connecting rod 28. The sealing head 24 moves downward and covers the bottle cap. As the connecting rod 28 continues to move downward, the sliding block 25 slides inside the connecting cylinder 26, compressing the sealing spring 27. The elastic force of the sealing spring 27 presses the sealing head 24 onto the bottle cap. The sealing layer 29 forms a sealed air inside the sealing head 24, which facilitates the detection component 3 to detect the airtightness of the bottle cap through the sealing head 24.

[0039] like Figures 3-5 As shown, the detection component 3 includes: a gas distribution plate 31, a gas supply valve 32, and a detector 33;

[0040] The gas distribution plate 31 rotates synchronously with the positioning component 1 and the rotating plate 21. An annular air chamber is provided inside the gas distribution plate 31. The gas distribution plate 31 has an inlet for connecting to the gas supply unit. The gas supply valve 32 is provided on the gas distribution plate 31 and is set corresponding to the sealing head 24. The inlet end of the gas supply valve 32 is connected to the annular air chamber and the outlet end is connected to the sealing head 24. The detector 33 is used to detect the change in air pressure inside the sealing head 24.

[0041] The gas supply unit introduces gas into the gas distribution plate 31 through the inlet. After the sealing head 24 seals the bottle cap, the gas is introduced into the sealing head 24 through the gas supply valve 32. When the detector 33 detects that the gas pressure in the sealing head 24 reaches the set value, the valve 32 is closed. If the gas pressure in the sealing head 24 does not decrease after a period of time, the bottle cap has good airtightness.

[0042] like Figures 3-5 As shown, the detection component 3 includes: a prompt panel 34 and a prompt light 35;

[0043] The indicator plate 34 is set corresponding to the detector 33, the indicator light 35 is fixed on the lifting plate, the indicator light 35 is connected to the detector 33, and the indicator light 35 is used to indicate the detection result of the bottle cap.

[0044] After the detector 33 has completed the airtightness test of the bottle cap, the detector 33 will control the indicator light 35 to light up according to the test results. The indicator light is red and green, with a green light for good airtightness and a red light for poor airtightness, so that workers can intuitively understand the airtightness status of the bottle cap.

[0045] like Figures 1-5 As shown, the guide track 41 has: a high section, a descending section, a low section, and an ascending section;

[0046] When the cam bearing 23 is in the high section, the probe mechanism 22 is not in contact with the bottle cap. When the cam bearing 23 is in the descending section, the probe mechanism 22 moves vertically downward relative to the rotating disk 21. When the cam bearing 23 is in the low section, the probe mechanism 22 covers the bottle cap. When the cam bearing 23 is in the ascending section, the probe mechanism 22 moves vertically upward relative to the rotating disk 21.

[0047] Above, refer to Figures 1-5 This invention describes a bottle cap airtightness testing device according to an embodiment of the present invention. The device achieves this by synchronously rotating the positioning component 1 and the rotating disk 21, ensuring that the probe mechanism 22 remains always above the bottle cap. The cam bearing 23 moves vertically on the rotating disk 21 via the guide rail 41, allowing the probe mechanism 22 to cover the bottle cap. This facilitates the testing component 3 in detecting the airtightness of the bottle cap through the probe mechanism 22. Throughout the process, the positioning component 1, the rotating disk 21, and the testing component 3 maintain synchronous rotation, enabling simultaneous airtightness testing of multiple bottle caps and improving the efficiency of bottle cap testing.
