[0026] Please see Figure 1-3This utility model provides an embodiment of an airtightness testing device for tin can processing: The device includes a frame 1 and a support frame 2. The frame 1 includes a conveying assembly 101, a servo motor 102, and guide bars 103. The conveying assembly 101 is located inside the frame 1. The servo motor 102 is located on one side of one end of the frame 1, providing power to the conveying assembly 101. Two sets of guide bars 103 are symmetrically arranged at both ends inside the frame 1, serving a guiding function to facilitate stable conveying of the tin cans. The support frame 2 includes a hydraulic cylinder 202, a pressure plate 203, a rubber sealing gasket 204, and an infrared sensor 205. The hydraulic cylinder 202 is located on top of the support frame 2. At the middle position of the part, the clamping plate 203 is located at the telescopic end of the hydraulic cylinder 202, and the rubber sealing gasket 204 is located at the bottom of the clamping plate 203, so that the clamping plate 203 and the rubber sealing gasket 204 can be in close contact with the opening of the tin can. The infrared sensor 205 is located at one end of the support frame 2, which can detect the position of the tin can and realize automatic and continuous detection of the airtightness of the tin can. A touch panel 104 is provided on one side of the other end of the frame 1, which acts as the host and can automatically control the detection equipment to perform airtightness detection. A support platform 105 is provided at the middle position inside the frame 1, which can support the tin can and improve the detection effect of the tin can. Both sides of the support frame 2 have passage openings 201 at the bottom.

[0027] Please refer to this carefully. Figure 1 and Figure 2 A booster pump 3 is installed at the bottom of one end of the support frame 2. An air filter 301 is installed at the air inlet of the booster pump 3 to filter dust and prevent it from entering the tin can. An air supply pipe 302 is installed at the air outlet of the booster pump 3. An air injection channel 303 is opened inside the pressure plate 203 to pressurize the tin can. A connecting pipe 304 is installed at the top of the pressure plate 203 at the position of the air injection channel 303. An electric control valve 305 is installed inside the connecting pipe 304 to control the opening and closing of the connecting pipe 304, which facilitates the detection of the air pressure of the tin can.

[0028] Please refer to this carefully. Figure 1 and Figure 3The conveying assembly 101 consists of a conveyor belt and two sets of rotating rollers. The output end of the servo motor 102 is connected to one set of rotating rollers, which can convey tin cans in an orderly manner, facilitating continuous inspection of tin cans. Support seats are provided at the four corners of the bottom of the frame 1. The hydraulic cylinder 202 is connected to the support frame 2 by bolts to install and fix the hydraulic cylinder 202. The rubber sealing gasket 204 is connected to the bottom of the pressure plate 203 by adhesive, which facilitates sealing of the opening of the tin can. The bottom of the pressure plate 203 is equipped with a pressure sensor, which can accurately detect the air pressure inside the tin can. The infrared sensor 205 is connected to the support frame 2 by bolts to detect the position of the tin can and accurately detect the airtightness of the tin can. The pressure plate 203 is connected to the telescopic end of the hydraulic cylinder 202 by bolts.

[0029] Please refer to this carefully. Figure 1 and Figure 2 The two ends of the support platform 105 are welded to the inner wall of the frame 1. Reinforcing blocks are provided on both sides of the bottom of the support platform 105 to provide support and reinforcement. When testing tin cans, the tin cans can be stably supported. The booster pump 3, infrared sensor 205, hydraulic cylinder 202, servo motor 102 and electric control valve 305 are electrically connected to the touch panel 104 through wires to realize automated testing of the air tightness of the tin cans. The top of the front end of the support frame 2 is provided with a wire hole, and the air supply pipe 302 passes through the wire hole to the inside of the support frame 2. The air supply pipe 302 is a rubber hose. The up and down adjustment of the pressure plate 203 can stretch and adjust the air supply pipe 302 to facilitate pressurization of the tin cans. The booster pump 3 is connected to the connecting pipe 304 through the air supply pipe 302. The booster pump 3 is connected to the support frame 2 by bolt installation, which can fix the booster pump 3 to the support frame 2.

[0030] Working Principle: When in use, the power is connected, and the tin can is placed upright on the conveyor belt with its opening facing upwards. The servo motor 102 provides power to the conveying assembly 101, transporting the tin can. Two sets of guide bars 103 position the tin can during transport until the infrared sensor 205 detects it. At this point, the hydraulic cylinder 202 moves the pressure plate 203 downwards, ensuring a tight contact between the opening of the tin can and the pressure plate 203 via the rubber sealing gasket 204. Simultaneously, the opening of the tin can is controlled to... Open the solenoid valve 305 to pressurize the tinplate can through the booster pump 3, air supply pipe 302, and air injection channel 303 until the maximum pressure threshold of the tinplate can is reached. Then close the solenoid valve 305 and observe whether the internal air pressure of the tinplate can changes. If there is no change, it means that the airtightness of the tinplate can meets the production standard. If the test fails, the equipment will stop operating until the unqualified tinplate can is manually removed. This allows for rapid testing of the airtightness of tinplate cans and improves the processing quality of tinplate cans.
