The first nuts 39 are sleeved on the outer side of the rotating shaft 35.The rotating shaft 35 is provided with a thread matched with the first nut 39, and the damping support structure includes a support ring 41 rotatably sleeved on both ends of the storage roller 5, and a clamping block 42 is fixedly connected to the bottom of the support ring 41. Two support blocks 43 are fixedly connected in the first installation box 1 and the second installation box 2, and a clamping groove 44 matched with the clamping block 42 is opened on the top of the support block 43. Two slide plates 46 are provided above the storage roller 5, and a damping plate 45 in contact with the storage roller 5 is fixedly connected to the bottom end of the slide plate 46. Two support sleeves 47 are fixedly connected in the first installation box 1 and the second installation box 2, and the top end of the slide plate 46 is located in the corresponding support sleeve 47.

[0040] The third compression spring 48 is initially in a compressed state, and the third compression spring 48 applies pressure to the slide plate 46 and the damping plate 45 to press the damping plate 45 on the storage roller 5, thereby reducing the possibility of the storage roller 5 rotating and shaking due to non-human factors, and the block 42 is inserted into the slot 44. The design of the block 42, the support block 43 and the movable ring 14 can prevent the storage roller 5 from shaking in the horizontal direction. The staff drives the rotating shaft 35 to rotate, and the rotating shaft 35 drives the two second bevel gears 37 to rotate synchronously. The second bevel gear 37 drives the worm 33 to rotate through the first bevel gear 36, and the worm 33 can drive the support shaft 7 to rotate through the worm gear 34, and the support shaft 7 drives the protrusion 21 to rotate synchronously through the first support portion 20. When the protrusion 21 slides from the inclined surface of the C-shaped bar 19 to the C When the C-shaped bar 19 moves away from one side of the movable ring 14, the protrusion 21 pushes the C-shaped bar 19 and the movable ring 14 to move toward the second damping disk 11, and the distance between the fixed ring 16 and the movable ring 14 becomes smaller. The pressure applied by the first compression spring 17 to the fixed ring 16 and the pressing column 15 reaches a preset value, and the pressing column 15 applies pressure to the second damping disk 11 through the ball 18, so that the friction force between the second damping disk 11 and the first damping disk 10 reaches a preset value, and at this time, the elastic pressing structure releases the pressing and fixing of the first mounting ring 3, so that the first mounting ring 3 and the second mounting ring 4 no longer clamp and fix the filter cotton 6. As the support shaft 7 rotates, the support shaft 7 drives the second damping disk 11 to rotate through the slider 13, and the second damping disk 11 can drive the second damping disk 11 to rotate through the friction force. A damping disc 10 rotates, and the first damping disc 10 drives the storage roller 5 located in the first installation box 1 to rotate. The filter cotton 6 wound on the storage roller 5 located in the first installation box 1 increases, and the filter cotton 6 wound on the storage roller 5 located in the second installation box 2 decreases. The storage roller 5 slides relative to the damping plate 45.

[0042] When the two storage rollers 5 need to be removed from the first installation box 1 and the second installation box 2 respectively, the staff drives the second nut 52 to rotate so that the second nut 52 is disengaged from the first screw rod 51, and the second nut 52 no longer presses the box cover 49, thereby releasing the fixation of the box cover 49. The staff drives the box cover 49 to move so that the box cover 49 is disengaged from the first screw rod 51, and the removal of the box cover 49 is completed. The staff drives the third nut 55 to rotate so that the third nut 55 is disengaged from the second screw rod 54, thereby releasing the limitation on the positions of the mounting plate 53 and the second mounting ring 4, and the staff drives the second mounting ring 4 in a direction away from the first mounting ring 3. The staff member drives the receiving roller 5 to move so that the receiving roller 5 is separated from the second screw rod 54, and the second receiving ring 4 is removed. The staff member cuts the filter cotton 6, drives the damping plate 45 to move, increases the length of the slide plate 46 in the support sleeve 47, and drives the receiving roller 5 to move so that the support ring 41 drives the card block 42 to separate from the card slot 44. The staff member drives the receiving roller 5 to move in the horizontal direction so that the receiving roller 5 passes through the second avoidance hole 50 and separates from the corresponding first installation box 1 or second installation box 2. The receiving roller 5 is removed. When the support shaft 7 rotates, the support shaft 7 drives the fixing column 23 in the rectangular ring 24, and the fixing column 23 pushes the rectangular ring 24 to reciprocate in the horizontal direction, and the third support portion 25 slides relative to the guide bar 26. The third support portion 25 and the guide bar 26 are designed to make the rectangular ring 24 move smoothly. When the horizontal distance between the rectangular ring 24 and the first mounting ring 3 reaches a preset value, the second compression spring 31 is in a compressed state, and the second compression spring 31 applies pressure to the fixing block 30 and the first mounting ring 3, so that the first mounting ring 3 and the second mounting ring 4 clamp the filter cotton 6. When the rectangular ring 24 moves in the opposite direction and the horizontal distance between the rectangular ring 24 and the first mounting ring 3 reaches a preset value, , the fixing frame 27 is in contact with the support plate 29. As the rectangular ring 24 continues to move, the rectangular ring 24 pushes the support plate 29, the movable column 28 and the fixed block 30 to move synchronously through the fixing frame 27, so that the first mounting ring 3 no longer clamps the filter cotton 6 with the second mounting ring 4. As the support shaft 7 continues to rotate, the first mounting ring 3 and the second mounting ring 4 can intermittently clamp the filter cotton 6. When the filter cotton 6 is not clamped by the first mounting ring 3 and the second mounting ring 4, the support shaft 7 can drive the storage roller 5 located in the first mounting box 1 to rotate synchronously, and move the new filter cotton 6 to between the first mounting ring 3 and the second mounting ring 4.

[0046] Step 3: The reeling moving assembly drives the filter cotton 6 to move, and reels the dirty filter cotton 6 away from between the first mounting ring 3 and the second mounting ring 4;

[0047] Step 4: Move the new filter cotton 6 between the first mounting ring 3 and the second mounting ring 4 to complete the replacement of the filter cotton 6.

[0048] Working principle: During operation, filtering is performed through the filter cotton 6 located between the second mounting box 2 and the first mounting ring 3. When the filter cotton 6 needs to be replaced, the elastic pressing structure releases the elastic pressing on the first mounting ring 3, so that the first mounting ring 3 and the second mounting ring 4 no longer clamp the filter cotton 6, and the winding moving component drives the filter cotton 6 to move, and the dirty filter cotton 6 is wound away from between the first mounting ring 3 and the second mounting ring 4, and the new filter cotton 6 is moved between the first mounting ring 3 and the second mounting ring 4, so that the replacement of the filter cotton 6 is completed, and the staff does not need to repeatedly separate the first mounting ring 3 and the second mounting ring 4, thereby reducing the frequency of opening the first mounting ring 3 and the second mounting ring 4, facilitating the later use and improving the convenience;

[0049] The third compression spring 48 is initially in a compressed state, and the third compression spring 48 applies pressure to the slide plate 46 and the damping plate 45 to press the damping plate 45 on the storage roller 5, thereby reducing the possibility of the storage roller 5 rotating and shaking due to non-human factors, and the block 42 is inserted into the slot 44. The design of the block 42, the support block 43 and the movable ring 14 can prevent the storage roller 5 from shaking in the horizontal direction. The staff drives the rotating shaft 35 to rotate, and the rotating shaft 35 drives the two second bevel gears 37 to rotate synchronously. The second bevel gear 37 drives the worm 33 to rotate through the first bevel gear 36, and the worm 33 can drive the support shaft 7 to rotate through the worm gear 34, and the support shaft 7 drives the protrusion 21 to rotate synchronously through the first support portion 20. When the protrusion 21 slides from the inclined surface of the C-shaped bar 19 to the C When the C-shaped bar 19 moves away from one side of the movable ring 14, the protrusion 21 pushes the C-shaped bar 19 and the movable ring 14 to move toward the second damping disk 11, and the distance between the fixed ring 16 and the movable ring 14 becomes smaller. The pressure applied by the first compression spring 17 to the fixed ring 16 and the pressing column 15 reaches a preset value, and the pressing column 15 applies pressure to the second damping disk 11 through the ball 18, so that the friction force between the second damping disk 11 and the first damping disk 10 reaches a preset value, and at this time, the elastic pressing structure releases the pressing and fixing of the first mounting ring 3, so that the first mounting ring 3 and the second mounting ring 4 no longer clamp and fix the filter cotton 6. As the support shaft 7 rotates, the support shaft 7 drives the second damping disk 11 to rotate through the slider 13, and the second damping disk 11 can drive the second damping disk 11 to rotate through the friction force. A damping disc 10 rotates, and the first damping disc 10 drives the storage roller 5 located in the first installation box 1 to rotate. The filter cotton 6 wound on the storage roller 5 located in the first installation box 1 increases, and the filter cotton 6 wound on the storage roller 5 located in the second installation box 2 decreases. The storage roller 5 slides relative to the damping plate 45. When the support shaft 7 drives the protrusion 21 to slide down from the C-shaped bar 19 through the first support portion 20, the protrusion 21 no longer supports the C-shaped bar 19 and the movable ring 14, and the first compression spring 17 pushes the movable ring 14 to move in the direction away from the fixed ring 16. The pressure applied by the first compression spring 17 to the fixed ring 16 and the pressing column 15 becomes smaller, and the friction between the second damping disc 11 and the first damping disc 10 is reduced to a preset value. Due to the third compression spring 48 Apply pressure to the slide plate 46 and the damping plate 45 so that the rotation of the storage roller 5 is resisted, and at this time the friction between the second damping disc 11 and the first damping disc 10 is reduced to a preset value, the first damping disc 10 and the storage roller 5 remain stationary, and as the second damping disc 11 continues to rotate, the second damping disc 11 cannot drive the first damping disc 10 and the storage roller 5 to rotate by friction, and at this time the elastic pressing structure presses and fixes the first mounting ring 3 again, and when the protrusion 21 slides to the side of the C-shaped bar 19 away from the movable ring 14 again, the elastic pressing structure releases the pressing and fixing of the first mounting ring 3 again, and as the rotating shaft 35 continues to rotate, the filter cotton 6 can be intermittently moved, and finally the new filter cotton 6 moves between the first mounting ring 3 and the second mounting ring 4,When the rotating shaft 35 does not need to be rotated, the staff drives two adjacent first nuts 39 to rotate, so that the two adjacent first nuts 39 clamp the fixing plate 38, so that the first nuts 39 and the rotating shaft 35 are fixed relative to the fixing plate 38 and the first installation box 1, reducing the possibility of the rotating shaft 35 rotating due to non-human factors;

[0050] When the two storage rollers 5 need to be removed from the first installation box 1 and the second installation box 2 respectively, the staff drives the second nut 52 to rotate so that the second nut 52 is disengaged from the first screw rod 51, and the second nut 52 no longer presses the box cover 49, thereby releasing the fixation of the box cover 49. The staff drives the box cover 49 to move so that the box cover 49 is disengaged from the first screw rod 51, and the removal of the box cover 49 is completed. The staff drives the third nut 55 to rotate so that the third nut 55 is disengaged from the second screw rod 54, thereby releasing the limitation on the positions of the mounting plate 53 and the second mounting ring 4, and the staff drives the second mounting ring 4 in a direction away from the first mounting ring 3. The staff member drives the receiving roller 5 to move so that the receiving roller 5 is separated from the second screw rod 54, and the second receiving ring 4 is removed. The staff member cuts the filter cotton 6, drives the damping plate 45 to move, increases the length of the slide plate 46 in the support sleeve 47, and drives the receiving roller 5 to move so that the support ring 41 drives the card block 42 to separate from the card slot 44. The staff member drives the receiving roller 5 to move in the horizontal direction so that the receiving roller 5 passes through the second avoidance hole 50 and separates from the corresponding first installation box 1 or second installation box 2. The receiving roller 5 is removed. When the support shaft 7 rotates, the support shaft 7 drives the fixing column 23 in the rectangular ring 24, and the fixing column 23 pushes the rectangular ring 24 to reciprocate in the horizontal direction, and the third support portion 25 slides relative to the guide bar 26. The third support portion 25 and the guide bar 26 are designed to make the rectangular ring 24 move smoothly. When the horizontal distance between the rectangular ring 24 and the first mounting ring 3 reaches a preset value, the second compression spring 31 is in a compressed state, and the second compression spring 31 applies pressure to the fixing block 30 and the first mounting ring 3, so that the first mounting ring 3 and the second mounting ring 4 clamp the filter cotton 6. When the rectangular ring 24 moves in the opposite direction and the horizontal distance between the rectangular ring 24 and the first mounting ring 3 reaches a preset value, , the fixing frame 27 is in contact with the support plate 29. As the rectangular ring 24 continues to move, the rectangular ring 24 pushes the support plate 29, the movable column 28 and the fixed block 30 to move synchronously through the fixing frame 27, so that the first mounting ring 3 no longer clamps the filter cotton 6 with the second mounting ring 4. As the support shaft 7 continues to rotate, the first mounting ring 3 and the second mounting ring 4 can intermittently clamp the filter cotton 6. When the filter cotton 6 is not clamped by the first mounting ring 3 and the second mounting ring 4, the support shaft 7 can drive the storage roller 5 located in the first mounting box 1 to rotate synchronously, and move the new filter cotton 6 to between the first mounting ring 3 and the second mounting ring 4.
