Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1, please refer to Figures 1-4 A dust removal device for leather spraying equipment based on high-efficiency activated carbon, comprising: The spraying box 100 has a placement platform 300 inside and an extraction head 600 connected to an air pump is slidably connected inside the spraying box 100. Dust collector 200, the interior of dust collector 200 is equipped with filter plate 400 and activated carbon adsorption layer 500 respectively; A rotating rod 701 is rotatably connected to the side of the extraction head 600. A fan 702 and a transmission cam 703 are fixedly connected to the outer side of the rotating rod 701. After completing the spraying operation on the leather placed on the placement table 300, the air pump is activated to extract the exhaust gas and dust from the spraying box 100 into the dust collection box 200 via the extraction head 600. At this time, the rapidly flowing airflow drives the fan 702 to rotate, and the rotating fan 702 drives the rotating rod 701 fixedly connected to it to rotate.

[0022] The spray box 100 is internally rotatably connected to a reciprocating lead screw 712 with internal damping. The extraction head 600 has internal threads and is threadedly mounted on the reciprocating lead screw 712. A transmission component for transmission is assembled between the transmission cam 703 and the reciprocating lead screw 712. The transmission component includes a hydraulic chamber 704 mounted on the top of the extraction head 600. A force-bearing rod 705 is slidably connected to the side of the hydraulic chamber 704 via a piston. A spring 705 is mounted on the side of the force-bearing rod 705. 6. A hydraulic hose 707 is installed on the top of the hydraulic chamber 1 704. A penetrating hydraulic chamber 2 708 is installed on the side of the spray box 100. The end of the hydraulic hose 707 away from the hydraulic chamber 1 704 is installed on the hydraulic chamber 2 708 and communicates with the hydraulic chamber 2 708. A lowering rod 709 is slidably connected to the bottom of the hydraulic chamber 2 708 by a piston. A tooth 711 is rotatably connected to the side of the lowering rod 709 by a torsion spring block 710. A gear 713 is fixedly connected to the outer side of the reciprocating screw 1 712. When gear 713 drives the reciprocating screw 712, which is fixedly connected to it, to rotate intermittently in one direction, it drives the extraction head 600, which is threaded onto the outside of the reciprocating screw 712, to move back and forth in the horizontal direction. This draws the exhaust gas and dust from various locations in the spray box 100 into the dust collection box 200, where they are treated by the filter plate 400 and the activated carbon adsorption layer 500, thus improving the dust removal efficiency of the device.

[0023] In use, after completing the spraying operation on the leather placed on the placement platform 300, the air pump is activated, and the exhaust gas and dust in the spraying box 100 are drawn into the dust collection box 200 through the extraction head 600. At this time, the rapidly flowing airflow drives the impeller 702 to rotate. The rotating impeller 702 drives the rotating rod 701 fixedly connected to it to rotate, so that the rotating rod 701 drives the transmission cam 703 fixedly connected to it to rotate. When the protruding part of the transmission cam 703 rotates to the force rod 705, it can squeeze the force rod 705 and drive the force rod 705 to move to the side. The mechanism is designed to work with the force rod 705. When the piston is slidably connected to the hydraulic chamber 704, the force rod 705 compresses the spring 706 and moves into the hydraulic chamber 704, squeezing the oil originally stored in the hydraulic chamber 704. The oil, under pressure, flows into the hydraulic hose 707 connected to the hydraulic chamber 704, causing some of the oil in the hose to flow into the hydraulic chamber 708 connected to it. This causes the oil in the hydraulic chamber 708 to flow towards the lower pressure rod 709, pulling the lower pressure rod 709, which is slidably connected to the hydraulic chamber 708 via a piston, out of the chamber. The lower pressure rod 709 then drives the torsion spring block 710. When tooth 711 moves downward a certain distance, it is restricted by the downward pressure rod 709 and cannot rotate around the torsion spring block 710. This causes the downward pressure rod 709 to drive gear 713 to rotate counterclockwise at a certain angle via tooth 711. When the protruding part of the transmission cam 703 moves away from the force rod 705 as it rotates, the force rod 705 loses the restriction of the transmission cam 703 and can reset under the action of spring 706. Similarly, the downward pressure rod 709 drives the torsion spring block 710 and tooth 711 to move upward to reset. At this time, tooth 711 is restricted by gear 713. The mechanism allows the torsion spring block 710 to rotate around the axis, thus avoiding the gear 713. In this way, the downward pressure rod 709, which is in a reciprocating motion state, can drive the gear 713 to rotate intermittently through the torsion spring block 710 and the teeth 711. This causes the gear 713 to drive the reciprocating screw 712, which is fixedly connected to it, to rotate intermittently in one direction. This, in turn, drives the extraction head 600, which is threaded onto the outside of the reciprocating screw 712, to move reciprocally in the horizontal direction, drawing the exhaust gas and dust from various locations in the spray box 100 into the dust collection box 200, where they are treated by the filter plate 400 and the activated carbon adsorption layer 500.

[0024] Example 2, please refer to Figures 1-6Based on Embodiment 1, a striking assembly 800 is installed at the bottom of the placement platform 300. The striking assembly 800 includes a torsion spring rod 801 rotatably connected to the side of the spray box 100. A transmission rod 1 802 and a transmission rod 2 803 are fixedly connected to the outer side of the torsion spring rod 801. A force-bearing rod 2 804 is hinged to the top of the transmission rod 1 802. The force-bearing rod 2 804 is located at the bottom of the pressing rod 709 and is in contact with the pressing rod 709. When the pressing rod 709 moves downward, the pressing rod 709 in the downward moving state can squeeze the force-bearing rod 2 804 and drive the force-bearing rod 2 804 to move downward together.

[0025] A striking block 805 is hinged to the side of the transmission rod 803. When the transmission rod 803 rotates, it can drive the striking block 805 to move. The striking block 805, which is in an upward moving state, can strike the elastic placement platform 300 to a certain extent, causing the placement platform 300 to vibrate to a certain extent.

[0026] A sprocket 806 is fixedly connected to the outer side of the reciprocating screw 712. When the reciprocating screw 712 rotates intermittently in one direction, it can drive the sprocket 806, which is fixedly connected to the reciprocating screw 712, to rotate synchronously.

[0027] A chain 807 is mounted on the outer side of sprocket 806. A through transmission rod 808 is rotatably connected inside the spray box 100. A sprocket 809 and a striking cam 810 are fixedly connected to the outer side of the transmission rod 808. The end of the chain 807 furthest from sprocket 806 is mounted on the outer side of sprocket 809. When the striking cam 810 rotates, it strikes the placement table 300 to a certain extent, shaking off residual dust and improving the dust removal efficiency of the device.

[0028] In use, based on Embodiment 1, when the pressing rod 709 moves downward, the pressing rod 709 in the downward moving state can squeeze the force-bearing rod 804 and drive the force-bearing rod 804 to move downward together. This causes the force-bearing rod 804 to drive the transmission rod 802, which is hinged to it, to move. The transmission rod 802 in the moving state can drive the torsion spring rod 801, which is fixedly connected to it, to rotate at a certain angle. This causes the torsion spring rod 801 to drive the transmission rod 803, which is fixedly connected to it, to rotate. The transmission rod 803 can then drive the striking block 805, which is hinged to it, to move. The striking block 805, which is in the upward moving state, can then strike the elastic placement platform 300. A certain degree of tapping causes the placement platform 300 to vibrate to a certain extent. When the reciprocating screw 712 rotates intermittently in one direction, it drives the sprocket 806, which is fixedly connected to the reciprocating screw 712, to rotate synchronously. In conjunction with the chain 807 mounted on the outside of the sprocket 806, the sprocket 809, which is connected to the sprocket 806 through the chain 807, rotates. The rotating sprocket 809 drives the transmission rod 808, which is fixedly connected to it, to rotate. The transmission rod 808 drives the striking cam 810, which is fixedly connected to it, to rotate. The rotating striking cam 810 taps the placement platform 300 to a certain extent.

[0029] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, the dust collector 200 is equipped with an auxiliary cleaning assembly 900, which includes a sprocket 901 fixed to the outside of the reciprocating screw 712. When the reciprocating screw 712 rotates, it drives the sprocket 901 fixedly connected to it to rotate.

[0030] Chain 2 902 is mounted on the outer side of sprocket 3 901. Reciprocating screw 2 903 is rotatably connected inside the dust collector 200. Sprocket 4 904 is fixedly connected to the outer side of reciprocating screw 2 903. One end of chain 2 902 away from sprocket 3 901 is mounted on the outer side of sprocket 4 904. Moving block 905 is threadedly connected to the outer side of reciprocating screw 2 903. Moving block 905 is located inside the dust collector 200 and is in a sliding connection with the dust collector 200. Gear 2 906 is rotatably connected to the bottom of moving block 905. Gear rack 907 is fixedly connected inside the dust collector 200. Gear rack 907 and gear 2 906 mesh. Cleaning brush 908 is fixedly connected to the bottom of gear 2 906. When gear 2 906 rotates synchronously during its reciprocating movement, it drives the cleaning brush 908, which is fixedly connected to it, to move together. This allows the filter plate 400 at its bottom to be cleaned by reciprocating rotation, preventing dust accumulation from affecting the filter plate 400's performance and further improving the efficiency of the device.

[0031] In use, based on Embodiments 1 and 2, when the reciprocating screw 712 rotates, it drives the sprocket 901 fixedly connected to it to rotate. This, in conjunction with the chain 902 mounted on the sprocket 901, causes the sprocket 904, which is connected to the sprocket 901 via the chain 902, to rotate. The rotating sprocket 904 then drives the reciprocating screw 903 fixedly connected to it to rotate. Simultaneously, the moving block 905, threaded onto the outside of the reciprocating screw 903, is restricted by the dust collector 200, causing the reciprocating screw to rotate... During the rotation of the second lead screw 903, the moving block 905 reciprocates in the horizontal direction. The moving block 905 then drives the second gear 906, which is rotatably connected to it, to reciprocate in the horizontal direction as well. The second gear 906, which is in the moving state, is simultaneously restricted by the gear 907 that meshes with it, so that the second gear 906 rotates during the movement. The rotating gear 906 can drive the cleaning brush 908, which is fixedly connected to it, to rotate, thereby performing a reciprocating rotational cleaning of the filter plate 400 located at its bottom.
