Description

Technical Field

[0001] This utility model relates to the field of aerosol can internal pressure detection technology, and in particular to an aerosol can internal pressure detection device. Background Technology

[0002] Aerosol cans are sealed containers that release liquids, gels, or powders in a mist, foam, or jet manner using internal pressure. They are widely used in daily chemicals, medical, and industrial fields. Their core feature is that they contain their own propellant, allowing for controlled release of the contents without the need for an external pump. After aerosol cans are manufactured, their internal pressure needs to be tested; therefore, an internal pressure testing device is used to perform this test.

[0003] In the existing technology, conventional internal pressure testing devices usually transport the aerosol can to the bottom of the testing mechanism first, then use a clamping structure to clamp and fix it, and then move the testing mechanism down to carry out the testing work. However, this process requires transportation, clamping and testing, which takes a certain amount of time and reduces the efficiency of the testing work. Utility Model Content

[0004] In view of this, the present invention provides an internal pressure detection device for aerosol cans. The main technical problem to be solved is that during the internal pressure detection of aerosol cans, clamping and detection cannot be carried out simultaneously, which reduces the efficiency of the detection work.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aerosol can internal pressure detection device, comprising a support base, a support frame fixedly connected to both sides of the upper surface of the support base, a support bracket fixedly connected to the upper surface of the support frame, two cylinders fixedly connected inside the support bracket, an installation plate fixedly connected to the telescopic ends of the two cylinders, a detection mechanism installed inside the installation plate, a rack plate fixedly connected to the lower surface of the installation plate, a bidirectional lead screw rotatably connected inside the support frame, gears fixedly connected to both ends of the outer wall of the bidirectional lead screw, the gears meshing with the rack plate, a push plate threadedly connected to the outer wall of the bidirectional lead screw, a slide rod slidably connected inside the push plate, a spring sleeved on the outer wall of the slide rod, and a clamping plate fixedly connected to the outer wall of the slide rod, wherein the elastic force of the spring is greater than the weight of the clamping plate.

[0006] By adopting the above technical solution, the pressure detection work is carried out by using a cylinder to drive the mounting plate and the detection mechanism to move downward. At the same time as the mounting plate moves downward, it drives the rack plate to move downward, causing the gear to rotate, which in turn drives the double-sided lead screw to rotate. The rotation of the double-sided lead screw drives the push plate to move towards the middle, which in turn drives the slide bar, spring and clamping plate to move towards the middle to achieve the clamping function. Thus, the clamping effect is achieved while the detection work is being carried out, reducing the time consumption of clamping before detection and improving work efficiency.

[0007] As a further description of the above technical solution: there are two bidirectional lead screws, which are symmetrically arranged inside the support frame; there are two push plates, which are symmetrically arranged on the outer walls of the two bidirectional lead screws; there are four gears and four rack plates, which are respectively arranged at both ends of the outer walls of the two bidirectional lead screws; and the four rack plates are respectively positioned corresponding to the four gears.

[0008] By adopting the above technical solution, two bidirectional lead screws are used in conjunction with four gears and four rack plates to drive two push plates to slide synchronously in the center, thereby achieving the clamping effect.

[0009] As a further description of the above technical solution: the detection mechanism includes pressure sensors, and five pressure sensors are provided, which are fixedly connected inside the mounting plate.

[0010] By adopting the above technical solution, pressure detection can be achieved using a pressure sensor.

[0011] As a further description of the above technical solution: a sealing cover is fixedly connected to the lower surface of the mounting plate, and five sealing covers are provided, with each of the five sealing covers corresponding to one of the five pressure sensors.

[0012] By adopting the above technical solution, the sealing cap is used to seal the upper port of the aerosol can and assist in pressure detection, while the detection end of the pressure sensor extends into the interior of the aerosol can.

[0013] As a further description of the above technical solution: a motor is fixedly connected to the inner wall of the support frame, and a synchronous wheel is fixedly connected to the output end of the motor, the synchronous wheel being rotatably connected inside the support frame.

[0014] By adopting the above technical solution, the starting motor drives the synchronous pulley to rotate.

[0015] As a further description of the above technical solution: a second synchronous wheel is rotatably connected inside the support frame, and a conveyor belt is rotatably connected to the outer wall of the first synchronous wheel, and the conveyor belt is rotatably connected to the outer wall of the second synchronous wheel.

[0016] By adopting the above technical solution, the rotation of synchronous wheel one drives the rotation of the conveyor belt, and the rotation of the conveyor belt drives the rotation of synchronous wheel two, thereby causing the conveyor belt to transport and unload the aerosol can.

[0017] As a further description of the above technical solution: five aerosol cans are placed on the upper surface of the conveyor belt, and the five aerosol cans are placed between the clamping plates.

[0018] By adopting the above technical solution, the aerosol can is placed on the upper surface of the conveyor belt for internal pressure testing, and the clamping plate clamps the aerosol can.

[0019] By employing the above technical solution, the aerosol can internal pressure detection device of this utility model has at least the following beneficial effects:

[0020] 1. Compared with the prior art, this aerosol can internal pressure detection device uses a starting cylinder to drive the mounting plate and detection mechanism to move downward to perform internal pressure detection. As the mounting plate moves downward, it also drives the rack plate to move downward, causing the gear to drive the bidirectional lead screw to rotate, which in turn drives the two push plates to slide in the center. This causes the slide rod, spring, and clamping plate to clamp the aerosol can, achieving the clamping effect while performing internal pressure detection, thus improving the efficiency of internal pressure detection.

[0021] 2. Compared with the prior art, the internal pressure detection device for aerosol cans has the following features: after the detection mechanism moves down, the sealing cover is sealed at the upper port of the aerosol can body, and the detection end of the pressure sensor is placed inside the aerosol can body, thereby achieving the effect of internal pressure detection. After the detection is completed, the cylinder drives the mounting plate, detection mechanism, push plate and other structures to reset, and the motor is started to drive the synchronous wheel one, the conveyor belt and the synchronous wheel two to rotate to transport and unload the aerosol can body.

Detailed Implementation

[0029] Reference Figure 1-5 This utility model provides an aerosol can internal pressure detection device, comprising a support base 1, with support frames 101 fixedly connected to both sides of the upper surface of the support base 1. Two support frames 101 are provided, and a support bracket 102 is fixedly connected to the upper surface of the support frame 101. Two cylinders 2 are fixedly connected inside the support bracket 102, and mounting plates 4 are fixedly connected to the telescopic ends of the two cylinders 2. A detection mechanism 3 is installed inside the mounting plate 4, which is used to detect the internal pressure of the aerosol can 16. A rack plate 5 is fixedly connected to the lower surface of the mounting plate 4. A bidirectional lead screw 6 is rotatably connected inside the support frame 101, and the bidirectional lead screw 6 is limited to rotate inside the two support frames 101. Gears 7 are fixedly connected to both ends of the outer wall of the bidirectional lead screw 6, and the gears 7 mesh with the rack plate 5. The outer wall of the bidirectional lead screw 6 is threaded. There is a push plate 8, which is set between the support frames 101 and is limited to move between the support frames 101. The push plate 8 is slidably connected to a slide rod 9. A spring 10 is sleeved on the outer wall of the slide rod 9. A clamping plate 11 is fixedly connected to the outer wall of the slide rod 9. The two ends of the spring 10 are respectively fixedly connected to the inside of the clamping plate 11 and the push plate 8. The elastic force of the spring 10 is greater than the weight of the clamping plate 11, and the weight of the push plate 8 is greater than the elastic force of the spring 10. There are two bidirectional lead screws 6, which are symmetrically arranged inside the support frames 101. There are two push plates 8, which are symmetrically arranged on the outer walls of the two bidirectional lead screws 6. There are four gears 7 and four rack plates 5. The four gears 7 are respectively arranged at both ends of the outer walls of the two bidirectional lead screws 6, and the four rack plates 5 are respectively positioned corresponding to the four gears 7.

[0030] The detection mechanism 3 includes pressure sensors 301, which are used to detect the internal pressure of the aerosol can 16. Five pressure sensors 301 are provided and fixedly connected inside the mounting plate 4. A sealing cover 302 is fixedly connected to the lower surface of the mounting plate 4. Five sealing covers 302 are provided and are used to seal the upper port of the aerosol can 16 to prevent inaccurate pressure detection. The five sealing covers 302 correspond to the five pressure sensors 301.

[0031] A motor 12 is fixedly connected to the inner wall of the support frame 101. A synchronous pulley 13 is fixedly connected to the output end of the motor 12. The synchronous pulley 13 is rotatably connected inside the support frame 101. A synchronous pulley 25 is rotatably connected inside the support frame 101. A conveyor belt 14 is rotatably connected to the outer wall of the synchronous pulley 13. The conveyor belt 14 is rotatably connected to the outer wall of the synchronous pulley 25. An aerosol can 16 is placed on the upper surface of the conveyor belt 14. The conveyor belt 14 is used to transport and unload the aerosol can 16. Five aerosol cans 16 are provided and placed between the clamping plates 11.

[0032] Working principle: When internal pressure testing of the aerosol can 16 is required, first connect the cylinder 2, pressure sensor 301, and motor 12 inside the device to the remote control equipment. Place the aerosol can 16 on the upper surface of the conveyor belt 14 and between the clamping plates 11. Start the cylinder 2 to move the mounting plate 4 and the detection mechanism 3 downwards. During the downward movement of the mounting plate 4, the rack plate 5 moves downwards, causing the gear 7 to rotate. The rotation of the gear 7 drives the bidirectional lead screw 6 to rotate, thereby achieving the central sliding of the two push plates 8. This drives the slide rod 9, spring 10, and clamping plates 11 to press against the aerosol can 16. The outer wall is clamped, and when the mounting plate 4 moves down to completely seal the sealing cap 302 at the upper end of the aerosol can 16, the clamping plate 11 has already clamped the outer wall of the aerosol can 16 in advance. The slide rod 9 and the spring 10 support the clamping plate 11, and can achieve the following: the clamping plate 11 has already clamped the aerosol can 16 before the push plate 8 has fully moved into place, while the sealing cap 302 has not yet fully contacted the upper end of the aerosol can 16. Thus, the clamping of the aerosol can 16 can be completed in advance during the downward movement of the detection mechanism 3. During operation, as the detection mechanism 3 continues to move downwards, the push plate 8 can continue to move. At this time, it only compresses the spring 10 and does not push the clamping plate 11 to over-clamp the aerosol can 16, ensuring that the aerosol can 16 is not damaged. When the sealing cap 302 is fully in contact with the upper end of the aerosol can 16 and seals the upper end of the aerosol can 16, the push plate 8 just reaches the outermost edge of the inner wall of the support frame 101. Therefore, it is possible to perform clamping work simultaneously with the detection work, and the clamping work is faster than the detection work. Compared with the prior art, which performs clamping work first and then detection work, this method is much faster. In terms of operation, it can effectively improve the efficiency of clamping and detection, and the speed can be faster. After the sealing cover 302 seals the upper end of the aerosol can 16, the detection end of the pressure sensor 301 is also placed inside the aerosol can 16 to start the internal pressure detection work. After the detection is completed, the cylinder 2 is started to drive the mounting plate 4 and the detection mechanism 3 to reset, causing the push plate 8 to drive the clamping plate 11 to slide to both sides, no longer clamping the aerosol can 16. Then the motor 12 is started to drive the synchronous wheel 13, the conveyor belt 14 and the synchronous wheel 15 to rotate, and transport and unload the aerosol can 16.
