[0022] A water tank 8 is fixedly provided on the upper end surface of the bottom plate 4 . Water is stored in the water tank 8 . A water pump is fixedly provided in the water tank 8 . A water outlet pipe 9 is fixedly connected to the water outlet end of the water pump.

[0023] The upper end surface of the bottom plate 4 is symmetrically slidably connected with a lifting mechanism 7, and a cleaning mechanism is slidably arranged between the two lifting mechanisms 7. The cleaning mechanism is used to clean the forming net body 3. A slide groove is opened at the upper end of the bottom plate 4. The lifting mechanism 7 includes an upper fixed plate 71, a cylinder 72, and a lower fixed plate 73. The lower fixed plate 73 is slidably connected in the slide groove of the bottom plate 4. The two lower fixed plates 73 can slide in the slide groove so that the two lower fixed plates 73 are close to or away from each other, so that the distance between the two lifting mechanisms 7 can adapt to the width of the forming net body 3. The cylinder 72 is fixedly arranged on the upper end surface of the lower fixed plate 73, and the output end of the cylinder 72 is fixedly connected to the upper fixed plate 71.

[0024] The cylinder 72 is started, and the output end of the cylinder 72 drives the upper fixing plate 71 to move in the vertical direction, so that the cleaning mechanism can move upward or downward, so that the cleaning mechanism adapts to the height of the forming net body 3 from the ground.

[0025] The sides of the two upper fixed plates 71 that are close to each other are rotatably connected with sleeves 10, and openings are set at the ends of the two sleeves 10 that face each other. A fixing column 14 is slidably connected between the insides of the two sleeves 10. The fixing column 14 and the sleeve 10 are provided with matching connecting holes 15, and the overlapping part of the fixing column 14 and the sleeve 10 is provided with an insert rod 16, which is inserted into the corresponding connecting holes 15 of the fixing column 14 and the sleeve 10 to fix the fixing column 14 and the sleeve 10, and the cleaning mechanism is set above the sleeve 10 and the fixing column 14.

[0026] When the lower fixed plate 73 moves in the slide groove, it will drive the corresponding sleeve 10 to move together. During this process, the fixed column 14 is stationary. After the distance between the two lifting mechanisms 7 is adapted to the width of the forming net body 3, the sliding of the lower fixed plate 73 is stopped, and the insertion rod 16 is inserted into the corresponding connecting hole 15 of the fixed column 14 and the sleeve 10 to achieve the fixation of the fixed column 14 and the sleeve 10, thereby achieving the fixation between the two lifting mechanisms 7.

[0028] When the rotation angle of the cleaning mechanism needs to be adjusted, the nut 17 is loosened and the hydraulic cylinder 13 is started. The output end of the hydraulic cylinder 13 drives the rack 12 to move, and the rack 12 drives the gear 11 to rotate. After the cleaning mechanism rotates to a suitable angle, the hydraulic cylinder 13 is stopped and the nut 17 is rotated to fix the sleeve 10 and the fixing column 14 as a whole to prevent the cleaning mechanism from rotating during use.

[0029] The cleaning mechanism includes two first fixing plates 18, which are symmetrically fixedly connected above the fixing column 14. The outside of the fixing column 14 is symmetrically fixedly sleeved with a connecting piece 20, which is connected to the corresponding first fixing plates 18. The end faces of the two first fixing plates 18 are arranged to fit each other, so that there is no cleaning dead corner when cleaning the forming net body 3. A plurality of brushes 181 are fixedly installed on the upper end faces of the two first fixing plates 18. The sides of the two first fixing plates 18 that are away from each other are provided with embedded holes 22. The backs of the two first fixing plates 18 are fixedly connected with a second fixing plate 19. The second fixing plate 19 is inclined. The sides of the two second fixing plates 19 that are away from each other are also provided with embedded holes 22. A plurality of nozzles 191 are fixedly installed on the second fixing plate 19. The nozzles 191 and the brushes 181 are used together to clean the forming net body 3. One end of the nozzle 191 is connected to a connecting pipe 192, and the other end of the connecting pipe 192 is connected to the water outlet pipe 9.

[0030] When the distance between the two lifting mechanisms 7 is adapted to the width of the forming net body 3, it is necessary to increase the number of cleaning mechanisms so that the cleaning mechanisms are evenly distributed between the two lifting mechanisms 7. The sides of the two first fixed plates 18 that are away from each other are detachably connected with a mounting plate 21, and a plurality of brushes 181 and a plurality of nozzles 191 are also arranged on the mounting plate 21. The side of the mounting plate 21 close to the first fixed plate 18 is fixedly connected with an embedded rod 211, and the embedded rod 211 is adapted to the embedded hole 22, and the embedded rod 211 can be inserted into the embedded hole 22 to realize the fixation of the mounting plate 21 and the first fixed plate 18. The side of the mounting plate 21 away from the first fixed plate 18 is also provided with an embedded hole 22, and the embedded hole 22 on the mounting plate 21 is used to connect with a subsequent mounting plate 21.

[0031] A guide plate 6 is fixedly provided at the upper end of the base plate 4, and the guide plate 6 includes an inner plate 61 and a guide plate body 62. The inner plate 61 and the guide plate body 62 are inclinedly arranged, and the lower end of the guide plate body 62 is fixedly connected to the base plate 4 through a rod body, and the two sides of the guide plate body 62 are slidably connected to the inner plate 61.

[0032] The upper end surface of the bottom plate 4 is fixedly provided with a collecting box 5 , and one end of the inner plate 61 and the guide plate body 62 extend into the interior of the collecting box 5 .

[0033] Working principle:

[0034] When it is necessary to clean the forming net body 3, the height of the lifting mechanism 7 from the ground is adjusted according to the height of the forming net body 3 from the ground, and the cylinder 72 is started. The output end of the cylinder 72 drives the upper fixed plate 71 to move in the vertical direction, so that the cleaning mechanism can move up or down, so that the cleaning mechanism adapts to the height of the forming net body 3 from the ground; when it is necessary to make the distance between the two lifting mechanisms 7 adapt to the width of the forming net body 3, the two lower fixed plates 73 slide in the slide groove so that the two lower fixed plates 73 are close to or away from each other. When the upper fixed plate 71 moves in the slide groove, it will drive the corresponding sleeve 10 to move together. After the distance between the two lifting mechanisms 7 is adapted to the width of the forming net body 3, stop sliding the upper fixed plate 71, and insert the insertion rod 16 into the corresponding connecting hole 15 of the fixing column 14 and the sleeve 10 to achieve the fixation of the fixing column 14 and the sleeve 10, thereby achieving the fixation between the two lifting mechanisms 7.

[0035] When the rotation angle of the cleaning mechanism needs to be adjusted, the nut 17 is loosened and the hydraulic cylinder 13 is started. The output end of the hydraulic cylinder 13 drives the rack 12 to move, and the rack 12 drives the gear 11 to rotate. After the cleaning mechanism rotates to a suitable angle, the hydraulic cylinder 13 is stopped and the nut 17 is rotated to fix the sleeve 10 and the fixing column 14 as a whole to prevent the cleaning mechanism from rotating during use.

[0036] When the distance between the two lifting mechanisms 7 is adapted to the width of the forming net body 3, it is necessary to increase the number of cleaning mechanisms so that the cleaning mechanisms are evenly distributed between the two lifting mechanisms 7: according to the distance between the two lifting mechanisms 7, the number of mounting plates 21 is appropriately increased on one side of each first fixed plate 18, and the embedded rod 211 is inserted into the embedded hole 22 to achieve the fixation of the mounting plate 21 and the first fixed plate 18.

[0037] When the forming mesh body 3 needs to be cleaned, the paper machine and the water pump are started, and the motor of the paper machine drives the forming mesh body 3 to operate. Since the brush 181 is in contact with the forming mesh body 3, the brush 181 will brush off or loosen the pulp adhering to the forming mesh body 3 during the operation of the forming mesh body 3. The nozzle 191 sprays out a high-pressure water flow to assist the brush 181 in brushing off the pulp, and the flushing water flows into the collection box 5 through the guide plate 6.

[0038] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
