Description

Technical Field

[0001] This utility model relates to the field of aerosol can processing technology, specifically a pneumatic edge-pressing device for sealing thin-walled aerosol cans. Background Technology

[0002] Thin-walled aerosol cans are lightweight, high-strength metal containers, usually made of aluminum alloy or tinplate. The can walls are thin to reduce weight. They are used to hold various spray products, such as cosmetics, insecticides, and cleaning agents. Precise spraying is achieved through a valve. They have advantages such as good sealing, ease of use, and portability.

[0003] Aerosol cans typically contain high-pressure gas and liquid or paste products. If the seal is not tight, leakage can easily occur, leading to product failure or even safety accidents. Therefore, a pneumatic sealing edge pressing device is required. However, traditional pneumatic sealing edge pressing devices are not convenient for clamping and fixing aerosol cans. If the aerosol can lacks effective clamping and fixing during the edge pressing process, it is easy for it to shake or shift. This will cause the edge pressing mold to not act accurately on the sealing part of the can, resulting in uneven force on the sealing edge, failure to form a tight fit, and thus gaps, affecting the sealing performance and increasing the risk of product leakage. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic sealing device for thin-walled aerosol cans to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic edge-pressing device for sealing thin-walled aerosol cans, including a workbench and a support base. The support base is installed on the top of the workbench, and a cylinder is fixedly connected to the inner wall of the support base. The piston rod of the cylinder is fixedly connected to a mold for pressing the edge of the seal.

[0006] A drive assembly is located on the top of the workbench. A positioning assembly for clamping the aerosol can is provided on one side of the drive assembly. The positioning assembly includes a clamping ring located on the top of the workbench. A sleeve rod is bolted to the outside of the clamping ring. The number of clamping rings and sleeve rods is set to four.

[0007] Preferably, the drive assembly includes a motor disposed on the top of the worktable, and a gear is fixedly connected to the output end of the motor.

[0009] Preferably, the outer side of the positive and negative threaded rod is threaded with two sets of moving blocks, and the bottom of each set of moving blocks is fixedly connected with a slider.

[0010] Preferably, the top of the worktable is provided with a groove for limiting the movement of the slider.

[0011] Preferably, a mounting base is fixedly connected to one side of the movable block, and the mounting block is rotatably connected to the inner wall of the mounting base via a rotating shaft.

[0012] Preferably, a sliding rod is fixedly connected to one side of the mounting block, and the outer side of the sliding rod is slidably connected to the inner wall of the sleeve rod.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, the pneumatic edge-pressing device for sealing thin-walled aerosol cans includes a workbench 1, a support base 2 mounted on top of the workbench 1, and a cylinder 3 fixedly connected to the inner wall of the support base 2. The piston rod of the cylinder 3 is fixedly connected to a mold 4 for pressing the edge of the sealing can. The workbench 1 serves as the basic support platform for the entire device, providing installation positions for other components and ensuring their stable and orderly arrangement and operation, thus guaranteeing the overall stability and reliability of the device. The support base 2, mounted on top of the workbench 1, is used to fix the cylinder 3, providing stable support and enabling the cylinder 3 to accurately perform the edge-pressing action, ensuring the precision and stability of the edge-pressing operation. The cylinder 3 is the power actuator of the device; through the extension and retraction of the piston rod, it drives the mold 4 to move up and down, realizing the edge-pressing operation for sealing the aerosol can. It converts the pressure energy of the pneumatic system into mechanical energy to complete the edge-pressing task. It should be noted that the cylinder 3... The system consists of an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and a flow control valve. During use, the air compressor compresses ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure before delivering it to the control valve via an air pipe. The directional control valve switches the airflow channel based on an electrical signal, determining the extension and retraction direction of cylinder 3. The flow control valve adjusts the airflow speed, controlling the movement speed of cylinder 3. Compressed air enters the rodless chamber or rodless chamber of cylinder 3, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion. The mold 4 is positioned to directly contact the sealing part of the aerosol can. Under the push of the piston rod of cylinder 3, pressure is applied to the seal, causing plastic deformation, thereby completing the edge sealing of the seal and ensuring the airtightness and structural strength of the aerosol can. It should be noted that the inner cavity of the mold 4 is hollowed out, and its size is suitable for the size of the can lid used in this application.

[0023] The drive assembly 5 is located on the top of the workbench 1. A positioning assembly 6 for clamping the aerosol can is provided on one side of the drive assembly 5. The positioning assembly 6 includes a clamping ring 61 located on the top of the workbench 1. A sleeve rod 62 is bolted to the outer side of the clamping ring 61, and there are four sets of both the clamping ring 61 and the sleeve rod 62. The clamping ring 61 is designed to directly contact the aerosol can to clamp it, ensuring its stable position during the edge pressing process, preventing it from shaking or shifting, and guaranteeing the accuracy of the edge pressing operation and the sealing quality. The sleeve rod 62 is bolted to the clamping ring 61 and slidably connected to the slide rod 12, providing guidance for the movement of the clamping ring 61. It is also rotatably connected to the mounting shaft 15, enabling flexible movement and position adjustment of the clamping ring 61. A protective pad made of sponge is provided inside the clamping ring 61. The design of the protective pad prevents the four sets of clamping rings 61 from contacting the aerosol can and causing damage to its appearance, further improving the stability during clamping and preventing the aerosol can from slipping. Figure 2 The middle clamping ring 61 is already in a clamping state, and the other part of the clamping ring 61, except for the clamping part, is arc-shaped. The arc-shaped design is to avoid affecting the removal of the aerosol can from the four sets of clamping rings 61, and also to avoid affecting the clamping ring 61 clamping the aerosol can.

[0024] The drive assembly 5 includes a motor 51 mounted on the top of the worktable 1, with a gear 52 fixedly connected to the output end of the motor 51. The drive assembly 5 also includes a rack 53 meshing with the outer side of the gear 52, and the inner wall of the rack 53 meshes with the outer side of another set of gears 52. Both sets of gears 52 have positive and negative threaded rods 54 fixedly connected to one side. The motor 51 serves as the power source for the drive assembly 5, providing power for the movement of the entire positioning assembly 6. Through the rotational movement of its output end, it drives the gear 52 to rotate, thereby driving the entire transmission system. The gear 52 and the output end of the motor 51... The rack 53 is connected to the moving block 7, which transmits the rotational motion of the motor 51 to the rack 53. The rack 53 is fixedly connected to the forward and reverse threaded rod 54, which drives the forward and reverse threaded rod 54 to rotate, thus realizing the transmission and conversion of power. The rack 53 meshes with the gear 52, realizing the transmission between the gears 52, so that the two sets of gears 52 can rotate synchronously, thereby making the two sets of forward and reverse threaded rods 54 rotate simultaneously. The forward and reverse threaded rod 54 is connected to the moving block 7 by threads, which converts the rotational motion into the linear motion of the moving block 7. When it rotates, it can make the two sets of moving blocks 7 move to the middle or both sides at the same time, thereby driving the positioning component 6.

[0025] Two sets of moving blocks 7 are threadedly connected to the outer side of the positive and negative threaded rod 54. The bottom of each set of moving blocks 7 is fixedly connected to a slider 8. A groove 9 is provided on the top of the worktable 1 to limit the movement of the slider 8. The moving block 7 is threadedly connected to the positive and negative threaded rod 54. Under the rotation of the positive and negative threaded rod 54, it achieves linear motion. Its movement drives the mounting base 10, mounting block 11, slider 12 and other components to move, thereby driving the positioning component 6 to clamp or release the aerosol can. The slider 8 is fixed to the bottom of the moving block 7 and cooperates with the groove 9 on the top of the worktable 1 to provide guidance and limit the movement of the moving block 7, ensuring that the moving block 7 can move stably and accurately along the predetermined direction, improving the movement accuracy and stability of the device. The groove 9 is opened on the top of the worktable 1 to provide a track for the movement of the slider 8, limit the movement direction of the slider 8, ensure that the moving block 7 will not deviate during the movement, and ensure the accuracy and stability of the movement of the positioning component 6.

[0026] A mounting base 10 is fixedly connected to one side of the movable block 7. The inner wall of the mounting base 10 is rotatably connected to the mounting block 11 via a rotating shaft. A sliding rod 12 is fixedly connected to one side of the mounting block 11, and the outer side of the sliding rod 12 is slidably connected to the inner wall of the sleeve rod 62. The mounting base 10 is fixed to one side of the movable block 7 and is rotatably connected to the mounting block 11 via a rotating shaft, so that the mounting block 11 can rotate within a certain range, realizing the flexible movement and position adjustment of the sliding rod 12. The mounting block 11 is rotatably connected to the mounting base 10 via a rotating shaft, so that the sliding rod 12 can move with the movement of the mounting block 11, realizing the sliding cooperation with the sleeve rod 62, thereby driving the clamping ring 61 to perform clamping or releasing operations on the aerosol can. The sliding rod 12 is fixed to one side of the mounting block 11 and is slidably connected to the inner wall of the sleeve rod 62. Driven by the movement of the mounting block 11, it slides within the sleeve rod 62, realizing the position adjustment of the clamping ring 61, and completing the clamping or releasing action on the aerosol can.

[0027] Four sets of support blocks 13 are fixedly connected to the top of the workbench 1. Each set of support blocks 13 has a mounting frame 14 fixedly connected to its top. A mounting shaft 15 is rotatably connected to the inner wall of the mounting frame 14, and one end of the mounting shaft 15 is rotatably connected to the outer side of the sleeve rod 62. The support blocks 13 are fixed to the top of the workbench 1 to provide support for the mounting frame 14, ensuring its stability and reliability, and thus ensuring the accurate installation positions of the mounting shaft 15 and the sleeve rod 62. The mounting frame 14 is fixed to the top of the support blocks 13 to provide an installation position for the mounting shaft 15, allowing it to rotate within the mounting frame 14, enabling flexible movement and position adjustment of the sleeve rod 62, and ensuring the clamping effect of the positioning component 6 on the aerosol can. The mounting shaft 15 is rotatably connected to the inner wall of the mounting frame 14, with one end rotatably connected to the outer side of the sleeve rod 62, providing rotational support for the sleeve rod 62, allowing it to rotate within a certain range, enabling flexible movement and position adjustment of the clamping ring 61, and ensuring stable and reliable clamping of the aerosol can.

[0028] Working principle: When clamping the aerosol can, first place the aerosol can at the center of the four clamping rings 61, then start the motor 51. Its output end drives the gear 52 to rotate. Since the rack 53 meshes with the gear 52, the two sets of gears 52 rotate synchronously, thereby driving the two sets of positive and negative threaded rods 54 to rotate. The positive and negative threaded rods 54 are threadedly connected to the moving block 7. When rotating, the rotational motion is converted into the linear motion of the moving block 7, causing the two sets of moving blocks 7 to move to both sides at the same time. The movement of the moving block 7 drives the mounting base 10 to move. The mounting base 10 rotates the mounting block 11 through the rotating shaft, thereby driving the slide rod 12 to rotate on the sleeve rod 62. The inner sliding sleeve 62 is connected to the clamping ring 61 and rotates with the mounting shaft 15. Driven by the slide rod 12, the clamping ring 61 moves towards the center. When the four sets of clamping rings 61 approach each other, they form a circular structure to clamp and fix the aerosol can. At this time, the cylinder 3 is turned on, which drives the mold 4 to move downward and applies pressure to the sealed end of the clamped aerosol can, causing it to undergo plastic deformation and complete the sealing edge sealing, ensuring the sealing performance and structural strength of the aerosol can. Then, the motor 51 is reversed to reset each set of drive structures, thereby causing the clamping ring 61 to expand outward, releasing the limit on the aerosol can, and the aerosol can can be removed.
