[0024] Refer to Figures 1-7, A felt cleaning device, including a box body 1. Both sides of the box body 1 are fixed with a frame body 2 by bolts. The top outer wall of the frame body 2 is fixed with an electric push rod 3 by bolts. The movable end of the electric push rod 3 passes through the frame body 2 and is fixed with a pressing plate frame 4 for dewatering the felt by bolts. A water falling mechanism for watering the felt is arranged between the inner walls on both sides of the frame body 2. The bottom inner wall of the box body 1 is fixed with a plurality of telescopic rods 15 by bolts. The top of the telescopic rods 15 is provided with a support frame 33 for supporting the felt, and the telescopic rods 15 and the support frame 33 are connected by a displacement mechanism for changing the position of the support frame 33. A locking mechanism for fixing the height of the support frame 33 is arranged on one outer wall of the box body 1. During use, place the felt product to be cleaned above the support frame 33, send water to the felt through the water falling mechanism to completely soak the felt, start the electric push rod 3, the electric push rod 3 extends, thereby pushing the pressing plate frame 4 to move downward, so as to gently squeeze the soaked felt, so that the water is squeezed out. Repeat this process until the squeezed water is clear, and the cleaning of the felt is completed. After the cleaning is completed, move the support frame 33 out of the box body 1 through the locking mechanism and the displacement mechanism, so as to take out the cleaned felt. There is no need for staff to wash by hand. Only need to take and replace the felt with a small amount of water after cleaning, and the cleaning operation of the felt can be completed, improving the protection of the staff.

[0025] In order to realize the flushing of the felt, in the present invention, the water falling mechanism includes guide rails 5 fixed on the inner walls on both sides of the frame body 2. A liquid distribution pipe 7 is slidably connected between the two guide rails 5. The bottom of the liquid distribution pipe 7 is fixed with a nozzle 9 by threads. One side of the liquid distribution pipe 7 is fixed with an external hose 8 connected to an external water pump by a hoop. A linear motor 6 is fixed on the inner wall of one side of the frame body 2 by bolts, and the movable end of the linear motor 6 is fixed to the liquid distribution pipe 7. A blocking mechanism for buffering the water sprayed by the nozzle 9 is arranged at the bottom of the liquid distribution pipe 7. Start the external water pump, the external water pump sends water into the liquid distribution pipe 7 through the external hose 8, then sprays out from the nozzle 9, and falls on the felt located on the support frame 33 after passing through the blocking mechanism to flush the felt. Drive the liquid distribution pipe 7 to reciprocate on the guide rail 5 through the linear motor 6 to simulate the staff flushing the felt and reduce the cleaning pressure of the staff.

[0026] In order to reduce the water pressure ejected by the nozzle 9, in the present invention, the blocking mechanism includes a water baffle frame 10 rotatably connected to both sides of the liquid distribution pipe 7 through a shaft. A plurality of water passing holes 11 are formed in the arc-shaped bottom of the water baffle frame 10. Fixed columns 13 are welded to the outer walls on both sides of the water baffle frame 10. Baffles 12 that can contact the fixed columns 13 are fixed to the bottoms of the two guide rails 5 through bolts. Torsion springs 14 fixed to the liquid distribution pipe 7 are fixed to both sides of the water baffle frame 10 through bolts. The water ejected by the nozzle 9 will fall on the water baffle frame 10, and then the water will flow down through the water passing holes 11, thereby flushing the felt, avoiding damage to the felt due to excessive water pressure ejected by the nozzle 9, improving the protection effect of the device. At the same time, when the water baffle frame 10 moves to the initial position, the baffle 12 will squeeze the fixed column 13, so that the water baffle frame 10 rotates, and then the water will flow from the water baffle frame 10 onto the felt completely. The torsion spring 14 can keep the water baffle frame 10 in a horizontal state during the movement, maintaining the pressure relief function of the water baffle frame 10.

[0027] In order to be able to move the support frame 33 out of the box body 1, in the present invention, the displacement mechanism includes a first fixing frame 16 fixed to the tops of the movable rods of a plurality of telescopic rods 15 through bolts. A first sliding frame 24 is slidably connected between the inner walls on both sides of the first fixing frame 16. An adjustment mechanism for driving the first sliding frame 24 to move is provided on one side of the first fixing frame 16. A second fixing frame 17 is fixed to the top of the first sliding frame 24 through bolts. A second sliding frame 25 is slidably connected between the inner walls on both sides of the second fixing frame 17. The first sliding frame 24 and the second sliding frame 25 move in the same direction through a linkage component. A fixing plate 28 that slidably contacts the support frame 33 is fixed to the top of the second sliding frame 25. The fixing plate 28 and the support frame 33 are supported by an elastic component. By driving the first sliding frame 24 to move through the adjustment mechanism, under the action of the linkage component, the second sliding frame 25 and the fixing plate 28 are driven to move together, so that the fixing plate 28 and the support frame 33 are moved out from the top of the box body 1, thereby facilitating the replacement of the felt and improving the convenience of felt replacement.

[0028] In order to drive the first sliding frame 24 to move, in the present invention, the adjustment mechanism includes a second motor 30 fixed to the outer wall on one side of the first fixing frame 16 through bolts. The output shaft of the second motor 30 passes through the first fixing frame 16 and is fixed to a lead screw 29 passing through the first sliding frame 24 through a coupling, and the lead screw 29 is threadedly connected to the first sliding frame 24. Starting the second motor 30, the second motor 30 drives the lead screw 29 to rotate. Under the action of the thread, the first sliding frame 24 moves in the first fixing frame 16, thereby driving the fixing plate 28 and the support frame 33 to move.

[0029] In order to make the first carriage 24 move in the same direction as the second carriage 25, in the present invention, the linkage assembly includes the same pull rope 26 fixedly connected to the first carriage 24 and the second carriage 25 respectively. Guide wheels 27 for guiding the pull rope 26 are fixedly mounted on both inner walls of the first fixing frame 16 by bolts, and the pull rope 26 is straightened after being supported by the guide wheels 27. A second spring 36 fixedly connected to the second carriage 25 is mounted on one side of the second fixing frame 17 by bolts. When the first carriage 24 moves, it will pull the pull rope 26 to move. Under the guidance of the guide wheels 27, the other end of the pull rope 26 will pull the second carriage 25 to move synchronously. When the second carriage 25 moves, it will squeeze the second spring 36 to contract and generate elastic force. When the first carriage 24 resets, the reset of the second spring 36 will push the second carriage 25, the fixing plate 28 and the support frame 33 to reset simultaneously. The first carriage 24 and the second carriage 25 moving in the same direction will increase the horizontal moving distance of the fixing plate 28 and the support frame 33, so that the felt can be completely removed from the top of the box body 1, further improving the convenience of felt replacement.

[0030] In order to support the support frame 33, in the present invention, the elastic assembly includes a first spring 35 fixed between the fixing plate 28 and the support frame 33. A plurality of limiting blocks 32 are fixedly mounted on both ends of the top of the fixing plate 28 by bolts, and the height of the limiting blocks 32 is higher than the height of the first spring 35 after being compressed to the limit. A plurality of inserting posts 31 are fixedly mounted on the top of the fixing plate 28 by bolts, and leakage holes 34 for inserting the inserting posts 31 are formed in the top of the support frame 33. During the downward movement of the pressing plate frame 4, the pressing plate frame 4 will squeeze the water on the felt, so that the water flows out from the leakage holes 34. When there is not much water on the felt, the downward movement of the pressing plate frame 4 will push the support frame 33 to move downward, thereby causing the first spring 35 to contract and generate elastic force until the support frame 33 contacts the limiting blocks 32. At the same time, the inserting posts 31 will be inserted into the leakage holes 34. When the support frame 33 contacts the limiting blocks 32, the top of the inserting posts 31 is flush with the top of the support frame 33, thereby assisting in supporting the felt and making the bottom of the felt flat, avoiding deformation of the felt and improving the protection effect of the device.

[0031] In order to fix the height of the support frame 33, in the present invention, the locking mechanism includes a rotating hole formed on one side of the box body 1. A connecting shaft 20 is rotatably connected in the rotating hole. A gear 19 and a worm gear 21 are respectively key-connected to both ends of the connecting shaft 20. A rack 18 meshing with the gear 19 is fixedly mounted on one side of the first fixing frame 16 by bolts. A first motor 23 is fixedly mounted on the outer wall of one side of the box body 1 by bolts. The output shaft of the first motor 23 is fixedly connected with a worm 22 meshing with the worm gear 21 through a coupling. When the first motor 23 is started, the first motor 23 drives the worm 22 to rotate, thereby driving the worm gear 21 to rotate, and then driving the gear 19 to rotate, so that the rack 18 and the first fixing frame 16 move upward or downward, thereby changing the height of the felt on the support frame 33, enabling the water for flushing the felt to fall into the box body 1, facilitating the secondary utilization of water resources and improving the environmental protection performance of the device.

[0032] Working principle of the present invention: When in use, place the felt product to be cleaned above the support frame 33, start the external water pump, the external water pump sends water into the liquid distribution pipe 7 through the external hose 8, and then sprays out from the nozzle 9. The water sprayed out by the nozzle 9 will fall on the water baffle frame 10, and the water will then flow down through the water passing holes 11 onto the felt to wash the felt. Drive the liquid distribution pipe 7 to reciprocate on the guide rail 5 through the linear motor 6 to reciprocally wash the felt; start the electric push rod 3, the electric push rod 3 extends, thereby pushing the pressing plate frame 4 to move downward, so as to gently squeeze the soaked felt, so that the water is squeezed out. During the process of the pressing plate frame 4 moving downward, the pressing plate frame 4 will squeeze the water on the felt, so that the water flows out from the leakage holes 34. When there is not much water in the felt, the downward movement of the pressing plate frame 4 will push the support frame 33 to move downward, thereby causing the first spring 35 to contract and generate elastic force until the support frame 33 contacts the limit block 32. At the same time, the plug post 31 will also be inserted into the leakage holes 34. When the support frame 33 contacts the limit block 32, the top of the plug post 31 is flush with the top of the support frame 33, thereby providing auxiliary support for the felt to make the bottom of the felt flush and preventing the felt from deforming. When the pressing plate frame 4 moves upward, the compressed first spring 35 resets and pushes the support frame 33 to reset, so that the support frame 33 is restored. Repeat this process until the squeezed water is clear, and the cleaning of the felt is completed. Start the first motor 23, the first motor 23 drives the worm 22 to rotate, thereby driving the worm gear 21 to rotate, and then driving the gear 19 to rotate, so that the rack 18 and the first fixing frame 16 move upward, so that the felt on the support frame 33 is moved out of the box body 1. Start the second motor 30, the second motor 30 drives the lead screw 29 to rotate. Under the action of the thread, the first sliding frame 24 moves in the first fixing frame 16. The movement of the first sliding frame 24 will pull the movement of the pull rope 26. Under the guidance of the guide pulley 27, the other end of the pull rope 26 will pull the second sliding frame 25 to move synchronously, and then the fixing plate 28 moves together, so that the fixing plate 28 and the support frame 33 are moved out of the top of the box body 1, and then the felt can be replaced.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0034] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
