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 Figures 1-3In this embodiment of the present invention, an aerosol can pretreatment device with a pressure relief structure includes a base 1, a support frame 2 fixedly connected to one side of the base 1, a sliding cavity 3 provided at the top of the support frame 2, a horizontal plate 4 slidably connected inside the sliding cavity 3, a first electric telescopic rod 5 fixedly connected to the top of the support frame 2, the telescopic end of the first electric telescopic rod 5 inserted into the sliding cavity 3 and fixedly connected to the horizontal plate 4, a compression sleeve 26 fixedly connected to the bottom surface of the horizontal plate 4 corresponding to the front of the support frame 2, a flexible hose connected to a waste gas collection device connected to the compression sleeve 26, a placement groove 6 provided below the compression sleeve 26 on the base 1, an aerosol can 7 placed in the placement groove 6, the placement groove 6 and the aerosol can 7 being adapted to each other, the compression sleeve 26 corresponding to and adapted to the top air outlet pipe of the aerosol can 7, a clamping and fixing mechanism 8 provided in the middle of the support frame 2, and a processing mechanism 9 provided on the outer side of the base 1 corresponding to the aerosol can 7.

[0023] The aerosol can 7 is positioned by placing it in the slot 6, and the horizontal plate 4 is raised and lowered by the first electric telescopic rod 5. The nozzle of the aerosol can 7 is then squeezed by the squeezing sleeve 26 to relieve pressure, thus avoiding danger caused by pressure problems when the processing mechanism 9 processes the aerosol can 7.

[0024] The clamping and fixing mechanism 8 includes an arc-shaped support base 10 and symmetrically arranged arc-shaped clamping bases 11. The arc-shaped support base 10 is fixedly connected to the support frame 2 and is adapted to the aerosol can 7. The arc-shaped clamping bases 11 are symmetrically arranged on both sides of the aerosol can 7 and are adapted to the aerosol can 7. The arc-shaped clamping bases 11 are fixedly connected to the end face of the aerosol can 7 with anti-slip pads.

[0025] Two guide rods 12 are symmetrically fixedly connected to the arc-shaped support base 10. The guide rods 12 slide through the two arc-shaped clamping seats 11. The arc-shaped clamping seats 11 are provided with circular holes for the guide rods 12 to pass through and slide. The opposite sides of the arc-shaped clamping seats 11 are staggered and fixedly connected with first racks 13. The first racks 13 slide through the arc-shaped support base 10. The arc-shaped support base 10 is rotatably installed with a first gear 14 corresponding to the first racks 13. The first gear 14 meshes with the two first racks 13 at the same time. The arc-shaped support base 10 is provided with mounting grooves for the sliding of the first racks 13 and the installation of the first gear 14.

[0026] After the central shaft of the first gear 14 rotates out of the arc-shaped support 10, it is fixedly connected to the second gear 15. The outer side of the second gear 15 is provided with a second rack 16 that meshes with it for transmission. The second rack 16 is slidably connected in the slide groove 17, and the slide groove 17 is fixedly connected to the back of the arc-shaped support 10.

[0027] A stop block 18 is fixedly connected to the bottom end of the slide groove 17. A vertical rod 19 slides through the second rack 16. A pull block 20 that matches the stop block 18 is fixedly connected to the bottom end of the vertical rod 19. The stop block 18 has a notch for the pull block 20 to pass through. A pressing arm 21 is fixedly connected to the top end of the vertical rod 19. The width of the pressing arm 21 matches the slide groove 17. A spring 22 sleeved on the outside of the vertical rod 19 is fixedly connected between the pressing arm 21 and the top end of the second rack 16. The pressing arm 21 is fixedly connected to the bottom surface of the horizontal plate 4.

[0028] The clamping and fixing mechanism 8 is positioned by the arc-shaped support base 10 and clamped by two arc-shaped clamping bases 11. During clamping, the second rack 16 is driven by the lifting and lowering of the horizontal plate 4, which in turn drives the two first racks 13 through the second gear 15 and the first gear 14. This causes the arc-shaped clamping base 11 to slide along the guide rod 12 to form a clamping and fixing effect. It can be fixed at the same time as the pressure relief operation, forming synchronous operation.

[0029] The compression arm 21 compresses the second rack 16 through the spring 22. The second rack 16 slides and is limited in the groove 17 by the stop block 18, so that the working effect of clamping and then releasing pressure can be achieved when the first electric telescopic rod 5 is working.

[0030] The processing mechanism 9 includes a motor 23, a cutting wheel 24, a movable frame 25, and a second electric telescopic rod 27. The movable frame 25 is slidably connected to the bottom inner side of the base 1. The second electric telescopic rod 27 is fixedly connected to the base 1, and the telescopic end of the second electric telescopic rod 27 is fixedly connected to the movable frame 25. The base 1 has a slot for mounting the second electric telescopic rod 27 and for sliding the movable frame 25. The motor 23 is fixedly installed inside the movable frame 25. The cutting wheel 24 is rotatably connected to the top surface of the movable frame 25 and extends to the top surface of the base 1. The base 1 has a slot for the connecting shaft of the cutting wheel 24 to pass through and move. The output end of the motor 23 is fixedly connected to the cutting wheel 24.

[0031] The moving frame 25 is moved by the second electric telescopic rod 27, and the cutting wheel 24 is rotated by the motor 23, so that the depressurized and clamped aerosol can 7 can be processed by the rotating cutting wheel 24.

[0032] The first electric telescopic pole 5, the motor 23, and the second electric telescopic pole 27 are all externally connected to a power source and a switch.

[0033] The working principle of this utility model is as follows:

[0034] In use, the aerosol can 7 to be processed is placed against the arc-shaped support 10 and inserted into the placement slot 6. At this time, the first electric telescopic rod 5 is activated, which drives the horizontal plate 4 to slide downward in the sliding cavity 3. At this time, the horizontal plate 4 moves the extrusion arm 21 and the extrusion sleeve 26 to descend. During the descent of the extrusion arm 21, the spring 22 compresses and drives the second rack 16 to descend in the sliding groove 17. The second rack 16 drives the second gear 15 to rotate, and the second gear 15 synchronously drives the first gear 14 to rotate. The first gear 14 drives the two arc-shaped clamps through the first rack 13. The seat 11 slides along the guide rod 12 until the second rack 16 presses against the stop block 18. At this time, the arc-shaped clamping seat 11 clamps and fixes the aerosol can 7 through the anti-slip pad. The horizontal plate 4 continues to descend, and the compression arm 21 compresses the spring 22 to maintain the clamping state. At this time, the compression sleeve 26 presses on the nozzle of the aerosol can 7 to form a pressure relief effect. At this time, the second electric telescopic rod 27 can drive the moving frame 25 to move, and the motor 23 can drive the cutting wheel 24 to rotate, thereby cutting the bottom of the aerosol can 7 to achieve pressure relief and pretreatment of the aerosol can 7. Then the second electric telescopic rod 27 resets, the motor 23 stops working, and the first electric telescopic rod 5 drives the horizontal plate 4 to reset. When the horizontal plate 4 resets, the compression arm 21 can drive the vertical rod 19 and the pull block 20 to pull the second rack 16 upward in the slide groove 17, thereby releasing the clamping fixation of the arc-shaped clamping seat 11, making it easy to remove the processed aerosol can 7.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
