Description

Technical Field

[0001] The invention relates to the technical field of papermaking equipment, in particular to an automatic tensioning device and a tensioning method for a papermaking forming net. Background Art

[0002] The papermaking industry is an industry with a long history. With the progress of human civilization and the development of society, the demand for paper has gradually increased. In the papermaking process, the forming mesh is an important equipment in the paper sheet forming process. It has the function of supporting fibers, fine materials and fillers, can remove a large amount of water in a short time, and plays a role in transmission between the headbox and the press section. Therefore, the forming mesh is an indispensable part of the papermaking industry.

[0003] The tensioning device of the papermaking forming fabric is a device specially designed for papermaking machines. Its main function is to adjust the tension of the forming fabric during the papermaking process. This device can ensure that the forming fabric maintains a stable tension during operation, thereby improving the quality and efficiency of papermaking. In existing papermaking machines, the tension of the forming wire is usually adjusted manually. When the papermaking production line is running, the operation of various mechanical parts and the flow of pulp will generate vibrations, which will be transmitted to the papermaking forming wire and cause it to be subjected to additional stress, thereby causing the papermaking forming wire to deform, resulting in the problem of loosening of the papermaking forming wire on the papermaking production line. Since manual work cannot be discovered and handled in time, the paper produced by the papermaking forming wire will be broken or wrinkled, reducing the quality of the produced paper; In addition, a large amount of wastewater is generated during the production process of paper, and the wastewater contains a large amount of wood fiber. The direct discharge of this wastewater will pollute the environment, cause the loss of papermaking materials, and increase the production cost of paper. Summary of the invention

[0011] As a preferred solution of the automatic tensioning device for papermaking forming mesh described in the present invention, the flushing component includes a collecting plate, a collecting box arranged on the base plate, a filter box arranged on the collecting box, and a clean water tank arranged on the base plate.

[0012] As a preferred solution of the automatic tensioning device for papermaking forming net described in the present invention, it comprises: a filter cartridge arranged on the filter box, a filter plate arranged on the filter cartridge, a box plate arranged on the filter box, a movable rod arranged on the box plate, a rotating rod arranged on the filter box, a locking hook symmetrically arranged on the rotating rod, and a trigger plate arranged on the locking hook.

[0013] To achieve the above object, the present invention provides the following technical solution: a tensioning method for an automatic tensioning device for a papermaking forming wire, comprising the following tensioning method: First, put the forming mesh on the driving roller. At this time, the hinge ring is not connected to the hinge column. By manually rotating the driving disk clockwise, the horn frame drives the tensioning roller to slide linearly along the column. At this time, the tensioning roller will adjust the tension of the forming mesh on the driving roller. When the tension of the forming net is adjusted to meet the current papermaking needs, the hydraulic rod 1 is manually rotated to sleeve the hinge ring set at one end of the hydraulic rod 1 on the hinge column. When the tension of the forming net changes after being used for a period of time, the hydraulic rod 1 will drive the driving disk to rotate through the hinge ring and the hinge column, and the bidirectional screw will drive the tension roller to shift; The spring in the telescopic cylinder pushes the telescopic rod to extend away from the telescopic cylinder. At this time, the hinge plate pushes the key shell and the cleaning roller is close to the surface of the forming mesh. During the displacement of the tension roller, the tension roller will drive the machine base and the motor installed thereon to shift synchronously. When the paper production line is running, the motor is started, and the motor output shaft will drive the synchronous wheel 1 and the synchronous wheel 2 to rotate clockwise, and the synchronous wheel 2 will drive the cleaning roller to rotate clockwise; When the tensioning component drives the tensioning roller and the tensioning shaft to shift along the column, the tensioning shaft forces the two locking blocks to avoid the tensioning shaft, and the locking blocks shrink into the elastic groove. When the tensioning shaft is separated from the locking blocks that shrink into the elastic groove, the locking blocks are reset under the rebound force of the second spring. When the tensioning roller applies tensioning force to the forming mesh, the forming mesh applies a reaction force to the tensioning roller, which causes the tensioning roller to obtain a resetting force. Since the two symmetrically arranged locking blocks are reset, the two locking blocks are reset and fit together. When installing or disassembling the forming net, by pressing the pressure plates on the two columns, the spring three is deformed and compressed, and the limit rod drives the limit block to slide in the limit groove. At this time, the locking blocks close to each other will move away from each other. At this time, remove the hinge ring from the hinge column and rotate the drive disk counterclockwise; At the same time, the pressure plate drives the lock tongue to move into the insertion groove. When the lock tongue moves to the position where the lock hole and the lock rod coincide with each other, the lock rod is inserted into the lock hole under the reset elastic force of spring four. At this time, the limit rod will be limited by the lock rod. When the lock rod needs to limit the tensioning shaft, the adjusting column is rotated, and the slide rod rotates along the slide groove. At this time, the lock rod will move in the direction away from the column and disengage from the lock hole. Under the reset elastic force of spring three, the limit rod, the limit block, the pressure plate, and the lock tongue are reset. At this time, the lock block is reset under the reset elastic force of spring two, and finally the adjusting column is rotated to reset the lock rod. The water in the pulp on the forming net is collected by the collecting plate and passed through the collecting box through the water pipe. Under the action of gravity, the water in the collecting box flows through the water outlet and water inlet troughs and then into the filter box. The hydraulic rod 2 is started to reciprocate and lift. During the descent of the filter cartridge, the filter cartridge will gradually move toward the direction of the base plate and block the water inlet trough. At this time, under the elastic force of the torsion spring 3, the box plate blocks the opening at the lower end of the filter box, and when the movable rod contacts and forces the locking hook to evade, the locking hook will hook the movable rod and limit the box plate. As the filter cartridge descends, the water pressure in the filter box increases, and the water in the filter box enters the clean water tank from the clean water tank through the filter plate. When the filter cartridge descends to the blocking filter plate and contacts the box plate, the filter cartridge will contact the trigger plate. At this time, the lock hook will no longer limit the movable rod, that is, the filter cartridge pushes the box plate to rotate around the hinge between it and the filter box. At this time, the limit plate will limit the rotation angle of the box plate. As the filter cartridge moves, the filter cartridge will force the movable rod to rotate to be stored in the movable tank. At the same time, as the filter cartridge moves, the wood fibers in the water in the filter box will be pushed out of the filter box and collected by the slide plate. When the hydraulic rod 2 drives the filter cartridge to rise and reset, the movable rod is reset under the elastic force of the torsion spring 2, and the box plate is reset under the elastic force of the torsion spring 3 and blocks the opening at the lower end of the filter box, and the lock hook will limit the movable rod again. When the filter cartridge rises to the limit position, the water in the collection box will continue to enter the filter box. The water entering the clean water tank from the filter box is pumped to the spray bar through the water pump and sprayed toward the cleaning roller. The excess water in the clean water tank will be collected into the water storage tank through the outlet pipe. Since the collection box is located at the lower end of the cleaning roller and the tensioning roller, the flushed water will be recycled into the collection box again.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By rotating the bidirectional screw rod, the tension roller is displaced, and then the papermaking forming net is adjusted to an appropriate tension. The hydraulic rod 1 is used to push the driving plate, so that when the papermaking forming net is deformed by vibration stress and the papermaking forming net is loose, the hydraulic rod 1 will drive the bidirectional screw rod to rotate through the driving plate, so that the tension roller is displaced along the column, so that the papermaking forming net that is loose due to deformation on the papermaking production line is properly tightened again, thereby avoiding the breakage or wrinkles of the paper produced by the papermaking forming net due to the looseness of the papermaking forming net, thereby improving the quality and aesthetics of the produced paper; 2. The motor is driven by the machine base to move synchronously with the tension roller, and the cleaning roller is driven by the motor to rotate, and the key shell is pushed up by the elastic component, so that the cleaning roller can clean the wood fiber remaining on the surface of the papermaking forming net, and the cleaning roller is sprayed with water by the water spray bar, so that the wood fiber on the surface of the papermaking forming net is cleaned and recovered into the collection box, thereby improving the water permeability of the papermaking forming net, avoiding the influence of the wood fiber remaining on the surface of the papermaking forming net on the quality of the subsequently produced paper, and further improving the quality of the produced paper; 3. The locking block is used to limit the tensioning shaft in real time, so that when the tensioning roller applies tension to the forming wire, the reaction force applied by the forming wire to the tensioning roller will not directly act on the bidirectional screw rod, thereby avoiding damage to the bidirectional screw rod due to excessive stress, thus ensuring the production efficiency of the paper production line; 4. The collected water is filtered into the clean water tank through the filter plate through the reciprocating motion of the hydraulic rod 2, and the limit of the movable plate is released by the locking hook and the movable rod and the trigger plate, so that the filter cartridge can filter out the wood fiber in the water and discharge it out of the filter box, and then the slide plate is used to collect the wood fiber filtered out by the filter box, so that the wood fiber in the water produced by paper production can be separated from the water and recycled, reducing the loss of papermaking materials and improving the utilization rate of papermaking materials.

A hinge column is arranged in an array at an eccentric position on one side of the driving disc 24. A hinge ring is fixedly installed at one end of the hydraulic rod 25 away from the base plate 1. When the tensioning roller 12 tensions the forming net to an appropriate tension, the hinge ring is hinged to the hinge column. When the forming net does not need to be tensioned or the tensioning roller 12 has not been tensioned by the forming net, the hinge ring is not connected to the hinge column. The tensioning component 2 further comprises a cleaning component 26 , which is used to remove residual wood fibers on the papermaking production line 11 .

[0029] The cleaning assembly 26 includes a key shell 27, a synchronous wheel 1 271 and a synchronous wheel 272 arranged in the key shell 27, a cleaning roller 28 arranged on the synchronous wheel 272, and a machine base 29 arranged on the column 41. The machine base 29 is slidably installed on the sides of the two columns 41 that are away from each other. A motor is fixedly installed on the machine base 29.

The cleaning roller 28 is rotationally connected to the other end of the key shell 27, and the synchronous wheel 2 272 is coaxially connected to the cleaning roller 28.

[0030] A fixed plate 211 is arranged on the horn rack 21, a hinged plate 212 is arranged on the fixed plate 211, and an elastic component 213 is arranged between the fixed plate 211 and the hinged plate 212.

[0031] During use, the forming net is firstly sleeved on the driving roller, and the cleaning roller 28 and the tensioning roller 12 are respectively located on both sides of the forming net belt, wherein the tensioning roller 12 is located on the inner side of the forming net belt, and the cleaning roller 28 is located on the outer side of the forming net belt. At this time, the hinge ring is not connected to the hinge column. The driving disk 24 is manually rotated clockwise, and then the screw rotates and drives the two nuts to gradually approach each other. The nuts pull the horn frame 21 and the tensioning roller 12 through the connecting rod 22, so that the horn frame 21 drives the tensioning roller 12 to slide linearly along the column 41. At this time, the tensioning roller 12 will adjust the tension of the forming net on the driving roller; When the tension of the forming net is adjusted to meet the current papermaking needs, the hydraulic rod 25 is manually rotated to sleeve the hinge ring provided at one end of the hydraulic rod 25 on the hinge column.

[0032] Example 2 Reference Figure 1-7, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: The locking block 42 is arranged in an array in the column 41, the limiting groove 421 is arranged in the locking block 42, the limiting rod 43 is symmetrically arranged in the column 41, and the limiting block 431 is arranged in an array on the limiting rod 43. Elastic grooves are provided on both sides of the locking groove. The locking block 42 is slidably installed in the elastic groove. A spring 2 is fixedly installed at the bottom of the elastic groove. The end of the spring 2 away from the bottom of the elastic groove is fixedly connected to one end of the locking block 42. A chamfered structure is provided at the end of the locking block 42 away from the spring 2. Unlocking grooves are symmetrically provided on the column 41. The limiting rod 43 is slidably installed in the unlocking groove. The limiting block 431 is slidably arranged in the limiting groove 421. A baffle is provided at one end of the limiting rod 43, and the baffle is located outside the unlocking groove. A spring 3 is sleeved on the outside of the limiting rod 43, and the spring 3 is located between the baffle and the column 41.

[0033] A pressure plate 44 is arranged on the column 41, a locking tongue 441 is arranged on the pressure plate 44, and a locking hole 442 is arranged on the locking tongue 441. The pressure plate 44 is slidably installed on the column 41, the pressure plate 44 is fixedly connected to the baffle, the locking tongue 441 is arranged at one end of the pressure plate 44 close to the column 41, and a chamfered structure is arranged at one end of the locking tongue 441 away from the pressure plate 44.

[0034] A mounting plate 45 is arranged on the column 41, a locking rod 46 is arranged on the mounting plate 45, and a lock cylinder 47 is arranged on the mounting plate 45. The mounting plate 45 is fixedly connected to the column 41, a fixing groove is opened on the mounting plate 45, a plug-in groove is opened on the mounting plate 45, the lock cylinder 47 is fixedly installed on the mounting plate 45, and the lock cylinder 47 is located at the position of the fixing groove, the locking rod 46 passes through the fixing groove and the lock cylinder 47, and one end of the locking rod 46 extends to the position of the plug-in groove, and sliding grooves are symmetrically opened on the side walls of the lock cylinder 47, and the sliding grooves are in a Z-shaped structure. A retaining ring is fixedly installed on the locking rod 46, and a spring four is sleeved on the outer side of the locking rod 46, the spring four is located in the fixing groove and respectively connects the retaining ring and the lock cylinder 47, and sliding rods are symmetrically installed on the locking rod 46, and the sliding rods are slidably installed in the sliding groove, and an adjusting column is fixedly installed on the other end of the locking rod 46.

[0035] During use, when the tensioning component 2 drives the tensioning roller 12 and the tensioning shaft to shift along the column 41, the tensioning shaft will contact the chamfered structure of the locking block 42, and the tensioning shaft will force the two locking blocks 42 to avoid the tensioning shaft. At this time, the locking block 42 shrinks into the elastic groove and the spring 2 is deformed and compressed. When the tensioning shaft is separated from the locking block 42 that shrinks into the elastic groove, the locking block 42 is reset under the action of the rebound force of the spring 2. When the tensioning roller 12 applies tensioning force to the forming mesh, the forming mesh applies a reaction force to the tensioning roller 12, which enables the tensioning roller 12 to obtain a reset force. Since the two symmetrically arranged locking blocks 42 are reset, the two locking blocks 42 are reset and fit together, so that the two locking blocks 42 limit the tensioning shaft, so that the tensioning roller 12 can maintain the forming mesh with appropriate tensioning force. When installing or removing the forming net, by pressing the pressing plate 44 on the two uprights 41, the spring three is deformed and compressed, and the limiting rod 43 drives the limiting block 431 to slide in the limiting groove 421. At this time, the locking blocks 42 close to each other will move away from each other, and the spring two is deformed and compressed. At this time, the hinge ring is removed from the hinge column and the driving disk 24 is rotated counterclockwise to drive the tension roller 12 to shift, so that the tight forming net becomes loose; At the same time, the pressing plate 44 drives the locking tongue 441 to move into the insertion slot. During the movement of the locking tongue 441, the chamfered structure on the locking tongue 441 pushes the locking rod 46, causing the locking rod 46 to move in a direction away from the column 41. At this time, the spring 4 is deformed and compressed. When the locking tongue 441 moves to the position where the locking hole 442 coincides with the locking rod 46, the locking rod 46 is inserted into the locking hole 442 under the restoring elastic force of the spring 44. At this time, the limiting rod 43 is limited by the locking rod 46. When the locking rod is needed to limit the tensioning shaft, the adjusting column is rotated, the locking rod 46 is rotated, and the sliding rod is rotated along the sliding groove. At this time, the locking rod 46 will move in the direction away from the column 41 and disengage from the locking hole 442. Under the reset force of spring three, the limit rod 43, the limit block 431, the pressure plate 44, and the locking tongue 441 are reset. At this time, the locking block 42 is reset under the reset force of spring two and can limit the tensioning shaft. Finally, the adjusting column is rotated to reset the locking rod 46.

A water outlet pipe is provided at the upper end of the side wall of the clean water tank 34, and the water outlet pipe is connected to the water storage tank, so that the water storage tank is connected with the inside of the clean water tank 34.

A connecting plate is fixedly installed on the filter cartridge 35, a hydraulic rod 2 is symmetrically installed on the base plate 1, and the telescopic end of the hydraulic rod 2 is fixedly connected to the connecting plate, the box plate 37 is hinged with the opening at the lower end of the filter box 33, and a torsion spring 3 is arranged at the hinge between the box plate 37 and the filter box 33, and a limit plate is symmetrically arranged on the filter box 33. The filter box 33 is provided with a mounting groove at one end away from the hinged connection with the box plate 37, and a rotating rod 331 is rotatably installed in the mounting groove. A torsion spring 1 is sleeved at the connection between the rotating rod 331 and the mounting groove. The angle between the locking hook 332 and the trigger plate 333 is 90°. Rotation grooves are symmetrically provided in the mounting groove. The trigger plate 333 passes through the rotation groove and extends into the filter box 33. A movable groove is provided at one end of the box plate 37 away from the hinged connection with the filter box 33, and a movable rod 371 is rotatably installed in the movable groove.

[0039] During use, the water in the pulp on the forming net is collected by the collecting plate 31 and passes through the collecting box 32 through the water pipe. Under the action of gravity, the water in the collecting box 32 flows through the water outlet and the water inlet and then into the filter box 33. The hydraulic rod 2 is started to reciprocate and lift. During the descent of the filter cartridge 35, the filter cartridge 35 will gradually move toward the direction of the base plate 1 and block the water inlet. At this time, under the elastic force of the torsion spring 3, the box plate 37 blocks the opening of the lower end of the filter box 33, and when the movable rod 371 contacts and forces the locking hook 332 to evade, the locking hook 332 will hook the movable rod 371 and limit the box plate 37. When the filter cartridge 35 is lowered, the water pressure in the filter box 33 increases, and the water in the filter box 33 enters the clean water tank 34 from the clean water tank through the filter plate 36. When the filter cartridge 35 is lowered to block the filter plate 36 and contact the box plate 37, the filter cartridge 35 will contact the trigger plate 333. At this time, the trigger plate 333 drives the rotating rod 331 to rotate under the action of the filter cartridge 35, and the rotating rod 331 drives the locking hook 332 to rotate. At this time, the locking hook 332 will no longer limit the movable rod 371, that is, the filter cartridge 35 pushes the box plate 37 to rotate around the hinge between it and the filter box 33. At this time, the limiting plate will limit the rotation angle of the box plate 37. As the filter cartridge 35 moves, the filter cartridge 35 will force the movable rod 371 to rotate to be stored in the movable groove. At the same time, as the filter cartridge 35 moves, the wood fibers in the water in the filter box 33 will be pushed out of the filter box 33 and collected by the slide plate. When the hydraulic rod 2 drives the filter cartridge 35 to rise and reset, the movable rod 371 is reset under the elastic force of the torsion spring 2, and the box plate 37 is reset under the elastic force of the torsion spring 3 and blocks the opening at the lower end of the filter box 33, and the lock hook 332 will limit the movable rod 371 again. When the filter cartridge 35 rises to the limit position, the water in the collection box 32 will continue to enter the filter box 33. The water entering the clean water tank 34 from the filter box 33 is pumped to the water spray bar by a water pump and sprayed in the direction of the cleaning roller 28, thereby flushing the dirt on the surface of the forming net after being wiped by the cleaning roller 28. The excess water in the clean water tank 34 will be collected into the water storage tank through the outlet pipe. Since the collection box 32 is located at the lower end of the cleaning roller 28 and the tensioning roller 12, the flushing water will be recovered into the collection box 32 again.

[0040] The remaining structure is the same as that of Example 2.

[0041] Example 4 Reference Figure 1-11 , which is a fourth embodiment of the present invention, provides: a tensioning method for an automatic tensioning device for a papermaking forming wire, comprising the following tensioning method, S1, firstly, the forming net is sleeved on the driving roller, at which time the hinge ring is not connected to the hinge column, and the driving disk 24 is manually rotated clockwise, so that the horn frame 21 drives the tensioning roller 12 to slide linearly along the column 41, and at this time the tensioning roller 12 will adjust the tension of the forming net on the driving roller; S2, when the tension of the forming net is adjusted to meet the current papermaking demand, the hydraulic rod 25 is manually rotated, and the hinge ring set at one end of the hydraulic rod 25 is sleeved on the hinge column. When the tension of the forming net changes after being used for a period of time, the hydraulic rod 25 will drive the driving disc 24 to rotate through the hinge ring and the hinge column, and the bidirectional screw 23 drives the tensioning roller 12 to shift; S3, the spring in the telescopic cylinder pushes the telescopic rod to extend in the direction away from the telescopic cylinder, at which time the hinge plate 212 pushes the key housing 27, and the cleaning roller 28 is close to the surface of the forming mesh; S4, during the displacement of the tension roller 12, the tension roller 12 will drive the machine base 29 and the motor installed thereon to shift synchronously. When the paper production line 11 is running, the motor is started, and the motor output shaft will drive the synchronous wheel 1 271 and the synchronous wheel 2 272 to rotate clockwise, and the synchronous wheel 2 272 will drive the cleaning roller 28 to rotate clockwise; S5, when the tensioning component 2 drives the tensioning roller 12 and the tensioning shaft to shift along the column 41, the tensioning shaft forces the two locking blocks 42 to avoid the tensioning shaft, and the locking blocks 42 shrink into the elastic groove. When the tensioning shaft is separated from the locking blocks 42 that shrink into the elastic groove, the locking blocks 42 are reset under the action of the rebound force of the second spring; S6, when the tensioning roller 12 applies tensioning force to the forming mesh, the forming mesh applies a reaction force to the tensioning roller 12, which makes the tensioning roller 12 obtain a resetting force. Since the two symmetrically arranged locking blocks 42 are reset, the two locking blocks are reset and fit together; S7, when installing or disassembling the forming net, by pressing the pressing plates 44 on the two uprights 41, the spring 3 is deformed and compressed, and the limiting rod 43 drives the limiting block 431 to slide in the limiting groove 421, and the locking blocks 42 close to each other will move away from each other. At this time, the hinge ring is removed from the hinge column and the driving disk 24 is rotated counterclockwise; S8, at the same time, the pressure plate 44 drives the lock tongue 441 to move into the insertion groove. When the lock tongue 441 moves to the lock hole 442 and coincides with the lock rod 46, the lock rod 46 is inserted into the lock hole 442 under the reset elastic force of the spring four. At this time, the limit rod 43 will be limited by the lock rod 46. When the lock rod needs to limit the tensioning shaft, the adjusting column is rotated, and the slide rod rotates along the slide groove. At this time, the lock rod 46 will move in the direction away from the column 41 and disengage from the lock hole 442. Under the reset elastic force of the spring three, the limit rod 43, the limit block 431, the pressure plate 44, and the lock tongue 441 are reset. At this time, the lock block 42 is reset under the reset elastic force of the spring two. Finally, the adjusting column is rotated to reset the lock rod 46. S9, water in the pulp on the forming net is collected by the collecting plate 31 and passed through the collecting box 32 through the water pipe. Under the action of gravity, the water in the collecting box 32 flows through the water outlet and the water inlet and then into the filter box 33. The hydraulic rod 2 is started to reciprocate and lift. During the descent of the filter cartridge 35, the filter cartridge 35 will gradually move toward the direction of the base plate 1 and block the water inlet. At this time, the box plate 37 blocks the opening at the lower end of the filter box 33 under the elastic force of the torsion spring 3, and the movable rod 371 contacts and forces the locking hook 332 to evade. At this time, the locking hook 332 will hook the movable rod 371 and limit the box plate 37. S10, as the filter cartridge 35 descends, the water pressure in the filter box 33 increases, and the water in the filter box 33 enters the clean water tank 34 from the clean water tank through the filter plate 36. When the filter cartridge 35 descends to block the filter plate 36 and descends to contact with the box plate 37, the filter cartridge 35 will contact the trigger plate 333. At this time, the lock hook 332 will no longer limit the movable rod 371, that is, the filter cartridge 35 pushes the box plate 37 to rotate around the hinge between it and the filter box 33. At this time, the limit plate will limit the rotation angle of the box plate 37. As the filter cartridge 35 moves, the filter cartridge 35 will force the movable rod 371 to rotate to be stored in the movable groove. At the same time, as the filter cartridge 35 moves, the wood fibers in the water in the filter box 33 will be pushed out of the filter box 33 and collected by the slide plate. S11, when the hydraulic rod 2 drives the filter cartridge 35 to rise and reset, the movable rod 371 is reset under the elastic force of the torsion spring 2, and the box plate 37 is reset under the elastic force of the torsion spring 3 and blocks the opening at the lower end of the filter box 33, and the lock hook 332 will limit the movable rod 371 again. When the filter cartridge 35 rises to the limit position, the water in the collection box 32 will continue to enter the filter box 33; S12, the water entering the clean water tank 34 from the filter box 33 is pumped to the water spray bar by a water pump and sprayed toward the cleaning roller 28. The excess water in the clean water tank 34 will be collected into the water storage tank through the outlet pipe. Since the collection box 32 is located at the lower end of the cleaning roller 28 and the tensioning roller 12, the flushed water will be recycled into the collection box 32 again.

A tensioning method for an automatic tensioning device for a papermaking forming wire according to claim 9, characterized in that: When the tensioning component (2) drives the tensioning roller (12) and the tensioning shaft to shift along the column (41), the tensioning shaft forces the two locking blocks (42) to avoid the tensioning shaft, and the locking blocks (42) shrink into the elastic groove. When the tensioning shaft is separated from the locking blocks (42) that have shrunk into the elastic groove, the locking blocks (42) are reset under the action of the rebound force of the second spring; When the tensioning roller (12) applies a tensioning force to the forming net, the forming net applies a reaction force to the tensioning roller (12), which causes the tensioning roller (12) to obtain a resetting force. Since the two symmetrically arranged locking blocks (42) are reset, the two locking blocks are reset and fit together; When the forming net is installed or removed, the pressing plates (44) on the two uprights (41) are pressed, and the spring three is deformed and compressed, and the limiting rod (43) drives the limiting block (431) to slide in the limiting groove (421), and the locking blocks (42) that are close to each other will move away from each other. At this time, the hinge ring is removed from the hinge column and the driving disk (24) is rotated counterclockwise; At the same time, the pressure plate (44) drives the lock tongue (441) to move into the insertion groove. When the lock tongue (441) moves to the lock hole (442) and coincides with the lock rod (46), the lock rod (46) is inserted into the lock hole (442) under the reset elastic force of the spring four. At this time, the limit rod (43) will be limited by the lock rod (46). When the lock rod needs to limit the tensioning shaft, the adjustment column is rotated, and the slide rod rotates along the slide groove. At this time, the lock rod (46) will move in a direction away from the column (41) and disengage from the lock hole (442). Under the reset elastic force of the spring three, the limit rod (43), the limit block (431), the pressure plate (44), and the lock tongue (441) are reset. At this time, the lock block (42) is reset under the reset elastic force of the spring two. Finally, the adjustment column is rotated to reset the lock rod (46). The water in the pulp on the forming net is collected by the collecting plate (31) and passes through the collecting box (32) through the water pipe. Under the action of gravity, the water in the collecting box (32) flows through the water outlet trough and the water inlet trough and then into the filter box (33). The hydraulic rod 2 is started to reciprocate and ascend. During the descent of the filter cartridge (35), the filter cartridge (35) gradually moves toward the base plate (1) and blocks the water inlet trough. At this time, under the elastic force of the torsion spring 3, the box plate (37) blocks the opening at the lower end of the filter box (33). When the movable rod (371) contacts and forces the locking hook (332) to evade, the locking hook (332) hooks the movable rod (371) and limits the box plate (37). As the filter cartridge (35) descends, the water pressure in the filter box (33) increases, and the water in the filter box (33) enters the clean water tank (34) from the clean water trough through the filter plate (36). When the filter cartridge (35) descends to the blocking filter plate (36) and descends to contact the box plate (37), the filter cartridge (35) will contact the trigger plate (333). At this time, the lock hook (332) will no longer limit the movable rod (371), so that the filter cartridge (35) pushes the box plate (37) to rotate around the hinge between it and the filter box (33). At this time, the limit plate will limit the rotation angle of the box plate (37). As the filter cartridge (35) moves, the filter cartridge (35) will force the movable rod (371) to rotate until it is stored in the movable trough. At the same time, as the filter cartridge (35) moves, the wood fibers in the water in the filter box (33) will be pushed out of the filter box (33) and collected by the slide plate. When the second hydraulic rod drives the filter cartridge (35) to rise and reset, the movable rod (371) is reset under the elastic force of the second torsion spring, the box plate (37) is reset under the elastic force of the third torsion spring and blocks the opening at the lower end of the filter box (33), and the lock hook (332) limits the movable rod (371) again. When the filter cartridge (35) rises to the limit position, the water in the collection box (32) will continue to flow into the filter box (33); The water entering the clean water tank (34) from the filter box (33) is pumped to the water spray bar by a water pump and sprayed toward the cleaning roller (28). Excess water in the clean water tank (34) is collected into the water storage tank through the water outlet pipe. Since the collection box (32) is located at the lower end of the cleaning roller (28) and the tensioning roller (12), the flushed water is recovered into the collection box (32) again.
