Description

Technical Field

[0001] This utility model relates to the field of aerosol can leak detection technology, specifically to a leak detection device for aerosol can filling equipment. Background Technology

[0002] Aerosol cans, as containers used to hold high-pressure gases and liquids, are widely used in the food, pharmaceutical, and chemical industries. Because their interiors are usually under high pressure, the sealing performance of aerosol cans is extremely important. After the aerosol cans are filled, strict leak testing must be carried out to prevent defective products from leaking into the market and to avoid potential safety risks.

[0003] Currently, the traditional method for leak detection of aerosol cans mainly uses water bath leak detection, which involves placing the filled aerosol can into water and observing whether bubbles are generated to determine if there is a leak. However, water bath leak detection requires a lot of manual operation, is inefficient, and the method of judging leaks by observing bubbles is not accurate enough, especially for detecting tiny leaks.

[0004] Therefore, it is necessary to invent a leak detection device for aerosol can filling equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a leak detection device for aerosol can filling equipment, so as to solve the problems of low detection efficiency and accuracy in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak detection device for aerosol can filling equipment, comprising a conveyor belt, with multiple sets of equidistantly distributed fixed supports fixedly connected to the upper side of the conveyor belt, the inside of the fixed supports holding the aerosol can body, and a detection component provided on the side of the conveyor belt, the detection component comprising an equipment base, a mounting plate, a hydraulic cylinder, an air pump, a detection sleeve, a pressure sensor, an air bladder, an inflation valve, and an inflation pipe, the hydraulic cylinder being fixedly installed in the middle of the mounting plate, the left end of the telescopic rod in the hydraulic cylinder being fixedly connected to the right end of the detection sleeve, and the pressure sensor being fixedly connected to the side wall of the detection sleeve.

[0007] By adopting the above technical solution, the gas tank body is transported by a conveyor belt and a fixed bracket. At the same time, the detection sleeve is pushed to the left by a hydraulic cylinder so that it fits onto the right end of the gas tank body. At this time, the air bladder is inflated by an air pump, so that the air bladder fits tightly against the surface of the gas tank body, keeping the inside of the detection sleeve sealed. The pressure sensor is then used to detect the internal pressure of the detection sleeve, thereby accurately detecting the sealing performance of the gas tank body, effectively improving detection efficiency and accuracy.

[0008] Optionally, positioning sleeves are fixedly connected to both the front and rear sides of the upper surface of the mounting plate, and positioning slide rods are slidably connected inside the positioning sleeves. Two sets of connecting blocks are fixedly connected to the side of the detection sleeve, and the left end of the positioning slide rod is fixedly connected to the connecting block.

[0009] By adopting the above technical solution, during the left and right movement of the detection sleeve, the positioning slide rod is driven to slide inside the positioning sleeve, which effectively improves the stability of the movement of the detection sleeve.

[0010] Optionally, a support frame is fixedly connected to the upper surface of the mounting plate, and the air pump is fixedly mounted on the upper surface of the support frame.

[0011] Optionally, two sets of airbags are fixedly connected to the inner wall of the detection sleeve near the left end, and the inflation valve is fixedly connected to the surface of the detection sleeve at the position above the airbags.

[0012] By adopting the above technical solution, the two sets of airbags work together to keep the inside of the detection sleeve in a sealed state.

[0013] Optionally, the right end of the inflation tube is fixedly connected to the air outlet of the air pump, and the left end of the inflation tube is fixedly connected to the upper end of the inflation valve.

[0014] By adopting the above technical solution, the air pump delivers compressed air to the inside of the airbag through the inflation pipe and inflation valve, inflating the airbag and making the airbag fit tightly against the surface of the air tank body.

[0015] Optionally, the upper surface of the equipment base is provided with three sets of limiting grooves, and linear guide rails are fixedly connected between the inner walls of the front and rear sides of the equipment base at the position below the left and right sets of limiting grooves. A precision screw is rotatably connected between the inner walls of the front and rear sides of the equipment base at the position below the middle limiting groove.

[0016] Optionally, a servo motor is fixedly installed on the front side of the equipment base, and the output end of the servo motor is fixedly connected to the front end of a precision screw via a coupling.

[0017] By adopting the above technical solution, a servo motor is used to drive a precision screw to rotate.

[0018] Optionally, positioning sliders are fixedly connected to both the left and right sides of the lower surface of the mounting plate. The lower end of the positioning slider passes through the limiting groove and is slidably connected to the linear guide rail. A transmission block is fixedly connected to the middle position of the lower surface of the mounting plate. The lower end of the transmission block passes through the limiting groove and is threadedly connected to the precision screw.

[0019] By adopting the above technical solution, with the cooperation of the positioning slider and the linear guide, the precision screw drives the transmission block to slide back and forth on its surface during rotation, thereby driving the mounting plate to slide back and forth, adjusting the position of the detection sleeve, so that the detection sleeve can be accurately fitted onto the right end of the gas tank body.

[0020] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0021] 1. This utility model utilizes a conveyor belt to transport the gas cylinder body, while a hydraulic cylinder pushes the detection sleeve to the left, so that it fits onto the right end of the gas cylinder body. An air bladder is used to seal the detection sleeve. At this time, a pressure sensor monitors the internal pressure of the detection sleeve in real time, thereby accurately detecting the sealing performance of the gas cylinder body, effectively improving detection efficiency and accuracy.

[0022] 2. This utility model uses a servo motor, precision screw, transmission block, linear guide rail and positioning slider to drive the mounting plate to slide back and forth on the surface of the equipment base, thereby adjusting the position of the detection sleeve so that it can be accurately fitted onto the right end of the gas tank body, avoiding gaps between the air bag and the gas tank body, and further improving the accuracy of the gas tank body sealing test.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1 to 5 The leak detection device shown is for an aerosol can filling equipment. It includes a conveyor belt 1, with multiple sets of equidistantly distributed fixed supports 11 fixedly connected to the upper side of the conveyor belt 1. The fixed supports 11 hold the aerosol can body 12. A detection assembly is provided on the side of the conveyor belt 1. The detection assembly includes an equipment base 2, a mounting plate 3, a hydraulic cylinder 33, an air pump 37, a detection sleeve 4, a pressure sensor 42, an air bladder 43, an inflation valve 44, and an inflation pipe 45. The hydraulic cylinder 33 is fixedly installed in the middle of the mounting plate 3. The left end of the telescopic rod in the hydraulic cylinder 33 is fixedly connected to the right end of the detection sleeve 4. The pressure sensor 42 is fixedly connected to the side wall of the detection sleeve 4. The mounting plate... Positioning sleeves 34 are fixedly connected to both the front and rear sides of the upper surface of the 3. Positioning slide rods 35 are slidably connected inside the positioning sleeves 34. Two sets of connecting blocks 41 are fixedly connected to the side of the detection sleeve 4. The left end of the positioning slide rod 35 is fixedly connected to the connecting block 41. A support frame 36 is fixedly connected to the upper surface of the mounting plate 3. An air pump 37 is fixedly installed on the upper surface of the support frame 36. Two sets of airbags 43 are fixedly connected to the inner wall of the detection sleeve 4 near the left end. An inflation valve 44 is fixedly connected to the surface of the detection sleeve 4 at the position above the airbags 43. The right end of the inflation pipe 45 is fixedly connected to the air outlet in the air pump 37. The left end of the inflation pipe 45 is fixedly connected to the upper end of the inflation valve 44.

[0033] During the sealing test of the gas tank body 12, the gas tank body 12 is transported by the conveyor belt 1. By placing the gas tank body 12 on the upper side of the fixed support 11, the conveyor belt 1 drives the gas tank body 12 to move backward through the fixed support 11, which effectively improves the convenience of transporting the gas tank body 12 and the efficiency of testing the gas tank body 12. At the same time, during the placement of the gas tank body 12, one end of its valve faces to the right.

[0034] Specifically, the conveyor belt 1 rotates intermittently, moving the gas tank body 12 to the left side of the detection component. At this time, the hydraulic cylinder 33 pushes the detection sleeve 4 to the left through its internal telescopic rod, and at the same time drives the positioning slide rod 35 to slide to the left inside the positioning sleeve 34, so that the detection sleeve 4 is fitted onto the right end of the gas tank body 12. Next, the air pump 37 is started. The air outlet of the air pump 37 delivers compressed air to the inside of the air bag 43 through the inflation pipe 45 and the inflation valve 44. At this time, the air bag 43 inflates, so that its surface is tightly attached to the surface of the gas tank body 12, and the inside of the detection sleeve 4 is sealed. At this time, the pressure sensor 42 monitors the pressure inside the detection sleeve 4 in real time, which can detect subtle pressure changes and effectively improve the detection accuracy of the gas tank body 12.

[0035] In addition, when the detection volume is large, multiple detection components can be set up to work together to increase the detection volume and further improve the detection efficiency.

[0036] See Figure 2 , Figure 3 and Figure 6 The upper surface of the equipment base 2 is provided with three sets of limiting grooves 21. Linear guide rails 23 are fixedly connected between the inner walls of the front and rear sides of the equipment base 2 at the lower side of the left and right sets of limiting grooves 21. A precision screw 24 is rotatably connected between the inner walls of the front and rear sides of the equipment base 2 at the lower side of the middle limiting groove 21. A servo motor 22 is fixedly installed on the front side of the equipment base 2. The output end of the servo motor 22 is fixedly connected to the front end of the precision screw 24 through a coupling. Positioning sliders 31 are fixedly connected to the left and right sides of the lower surface of the mounting plate 3. The lower end of the positioning slider 31 passes through the limiting groove 21 and is slidably connected to the linear guide rail 23. A transmission block 32 is fixedly connected to the middle position of the lower surface of the mounting plate 3. The lower end of the transmission block 32 passes through the limiting groove 21 and is threadedly connected to the precision screw 24.

[0037] Meanwhile, due to the deviation in the position of the gas tank body 12 during the long-term transportation process of the conveyor belt 1, the servo motor 22 is started. The output end of the servo motor 22 drives the precision screw 24 to rotate. At this time, with the cooperation of the positioning slider 31 and the linear guide rail 23, the precision screw 24 drives the transmission block 32 to slide back and forth on its surface during rotation, thereby driving the mounting plate 3 to slide back and forth, adjusting the position of the detection sleeve 4, so that the detection sleeve 4 can be accurately fitted on the right end of the gas tank body 12, further improving the detection accuracy.

[0038] The working principle of this utility model is as follows: The gas tank body 12 is conveyed by the conveyor belt 1, and the detection sleeve 4 is pushed to the left by the hydraulic cylinder 33 so that it fits on the right end of the gas tank body 12. The detection sleeve 4 is sealed by the air bag 43. At this time, the pressure sensor 42 monitors the internal pressure of the detection sleeve 4 in real time, thereby accurately detecting the sealing performance of the gas tank body 12, effectively improving the detection efficiency and accuracy. At the same time, the servo motor 22, precision screw 24, transmission block 32, linear guide rail 23 and positioning slider 31 work together to drive the mounting plate 3 to slide back and forth on the surface of the equipment base 2, thereby adjusting the position of the detection sleeve 4 so that it can be accurately fitted on the right end of the gas tank body 12, avoiding gaps between the air bag 43 and the gas tank body 12, and further improving the accuracy of the sealing performance detection of the gas tank body 12.
