[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1 - Figure 4This utility model provides a technical solution: a papermaking device for yarn tubes, including a placement component 3 for holding pulp; a limiting component 1 disposed on the bottom surface of the placement component 3 for limiting and fixing the placement component 3; and a pressing component 2 disposed on the top surface of the limiting component 1 for pressing the top of the placement component 3. When papermaking is required, the limiting component 1 is first placed in the preset position, and then the pressing component 2 is fixedly connected to the top surface of the limiting component 1. Since the placement component 3 is movably connected to the inner cavity of the limiting component 1, the limiting component 1 can limit and fix the placement component 3, thereby pressing the output end of the pressing component 2 against the top of the limiting component 1 to maintain the seal between the limiting component 1 and the pressing component 2. Then, through the pressing component 2, the worker can add pulp into the inner cavity of the pressing component 2, thereby allowing the placement component 3 to place the pulp. Then, through the limiting component 1, the water in the pulp can be discharged, thereby evenly leaving the pulp in the inner cavity of the placement component 3, thereby allowing the pressing component 2 to dewater the pulp in the inner cavity of the placement component 3, thereby enhancing the compactness and strength of the pulp.
[0017] See Figure 1 , Figure 2 The limiting component 1 includes a worktable 11. A limiting cylinder 12 is provided at the center of the top surface of the worktable 11. A first limiting groove 13 is formed on the top surface of the limiting cylinder 12. A top plate 14 is provided inside the limiting cylinder 12. A first telescopic rod 15 is provided at the center of the bottom surface of the top plate 14. A lifting plate 16 is provided on the outer side of the center of the bottom surface of the top plate 14. A second telescopic rod 17 is provided on the bottom surface of the lifting plate 16. There are three second telescopic rods 17 arranged in a circular array. The components are arranged in a column. A drain pipe 18 is provided on one side of the limiting cylinder 12. A movable groove 110 is provided in the center of the top surface of the worktable 11. A lead screw 111 is provided on both sides of the inner cavity of the movable groove 110. A servo motor 112 is provided at one end of the lead screw 111. A movable plate 113 is provided on the outside of the lead screw 111. The top of the movable plate 113 is connected to the bottom surface of the limiting cylinder 12. A locking groove 19 is provided on the top surface of the limiting cylinder 12 and outside the first limiting groove 13. The locking groove 19 is connected to the pressing assembly 2. The worktable 11 in the limiting assembly 1 can be placed in a preset position and also provides an installation base for the limiting cylinder 12. Since the top surface of the limiting cylinder 12 has a first limiting groove 13, and the inner cavity of the limiting cylinder 12 is movably connected to a top plate 14, while the bottom surface of the top plate 14 is fixedly connected to a first telescopic rod 15, the worktable 11 can provide support for the limiting cylinder 12. This allows the first limiting groove 13 to limit and fix the placement assembly 3, thereby improving the stability of the placement assembly 3. Then, through the first telescopic rod 15, the placement assembly 3 can be... While extending and retracting the output end of the first telescopic rod 15, the top plate 14 moves up and down, thereby lifting the placement component 3 and improving the stability of dehydration within the cavity of the placement component 3. A lifting plate 16 is movably connected to the outer side of the center of the bottom surface of the top plate 14, and a second telescopic rod 17 is fixedly connected to the bottom surface of the lifting plate 16. Three second telescopic rods 17 are fixedly connected, and a drain pipe 18 is embedded in one side of the limiting cylinder 12. Thus, while extending and retracting the output ends of the three second telescopic rods 17, the lifting plate 16 moves up and down. The lifting plate 16 can be adjusted so that when the top plate 14 lifts the placement component 3, the lifting plate 16 can be lowered, thereby draining the water generated during the dehydration of the placement component 3 through the drain pipe 18, thus improving convenience. A movable groove 110 is provided in the center of the top surface of the workbench 11, and lead screws 111 are rotatably connected to both sides of the inner cavity of the movable groove 110. A servo motor 112 is rotatably connected to one end of the lead screw 111, and a movable plate 113 is fixedly connected to the outside of the lead screw 111, thereby allowing the output end of the servo motor 112 to rotate. Simultaneously, the movement drives the lead screw 111 to rotate, thereby adjusting the position of the movable plate 113. This allows the movable plate 113 to move the limiting cylinder 12, facilitating the adjustment of the position of the limiting cylinder 12. Since the top surface of the limiting cylinder 12, located outside the first limiting groove 13, has a locking groove 19, and the locking groove 19 is connected to the pressing component 2, the pressing component 2 can be inserted into the inner cavity of the locking groove 19. This allows the locking groove 19 to limit the pressing component 2, thereby improving the sealing between the limiting cylinder 12 and the pressing component 2.
[0018] See Figure 1 , Figure 3The holding assembly 2 includes a gantry frame 21, which is mounted on the top surface of the workbench 11. Lifting cylinders 22 are mounted on both sides of the inner cavity of the gantry frame 21. Three third telescopic rods 23 are mounted on the top surfaces of both lifting cylinders 22, arranged in a circular array. An inlet pipe 24 is positioned centrally on one side of the top surface of the gantry frame 21. A telescopic pipe 25 is mounted at the output end of the inlet pipe 24, and the output end of the telescopic pipe 25 is connected to one of the lifting cylinders 22. The bottom surfaces of both lifting cylinders 22 are... A second limiting groove 26 is provided. Both lifting cylinders 22 have locking plates 27 on their bottom surfaces and located in the second limiting groove 26. The locking plates 27 are connected to the locking groove 19. A fourth telescopic rod 28 is provided at the center of the top surface of the other lifting cylinder 22. A pressure plate 29 is provided at the output end of the fourth telescopic rod 28. The outer diameter of the pressure plate 29 is the same as the inner diameter of the other lifting cylinder 22 when viewed from above, and the two are compatible. The outer diameter and inner diameter of the limiting cylinder 12, one of the lifting cylinders 22 and the other lifting cylinder 22 are the same when viewed from above, and they are compatible. The gantry frame 21 in the holding assembly 2 can be fixedly connected to the top surface of the workbench 11 and provide an installation base for the two lifting cylinders 22. Since three third telescopic rods 23 are embedded in the top surface of each of the two lifting cylinders 22, and these three third telescopic rods 23 are arranged in a circular array, the workbench 11 can support the gantry frame 21. This allows the output end of the third telescopic rod 23 to extend and retract, simultaneously moving the lifting cylinders 22 up and down, thus adjusting their position and ensuring they fit snugly against the limiting cylinder 12. An inlet pipe 24 is embedded in the center of one side of the top surface of the gantry frame 21, and a telescopic pipe 25 is fixedly connected to the output end of the inlet pipe 24. The output end of the telescopic pipe 25 is connected to one of the lifting cylinders 22, allowing workers to add pulp into the inner cavity of the inlet pipe 24. The pulp in the inner cavity of the inlet pipe 24 is then added to one of the lifting cylinders 22 via the telescopic pipe 25. The inner cavity of each lifting cylinder 22 is designed to allow pulp to be added into the inner cavity of the placement component 3. Since the bottom surfaces of both lifting cylinders 22 are provided with second limiting grooves 26, and both lifting cylinders 22 have locking plates 27 fixedly connected to their bottom surfaces within the second limiting grooves 26, and these locking plates 27 are connected to locking grooves 19, the locking plates 27 can be inserted into the inner cavity of the locking grooves 19, thereby engaging the second limiting grooves 26 with the top surface of the placement component 3. This improves the sealing between the two lifting cylinders 22 and the limiting cylinders 12. A fourth telescopic rod 28 is embedded in the center of the top surface of the other lifting cylinder 22, and a pressure plate 29 is fixedly connected to the output end of the fourth telescopic rod 28. This allows the pressure plate 29 to move up and down while the output end of the fourth telescopic rod 28 extends and retracts, thus pressing the pulp in the inner cavity of the placement component 3. This allows the pressure plate 29 to dewater the pulp in the inner cavity of the placement component 3, thereby improving its compactness and strength.
[0019] See Figure 1 , Figure 4 The placement component 3 includes a placement ring 31, which is disposed in the inner cavity of the first limiting groove 13. A mesh plate 32 is disposed in the inner cavity of the placement ring 31. A C-shaped hole 33 is opened on one side of the inner cavity of the placement ring 31. Multiple C-shaped holes 33 are opened and distributed in a circular array. A filter screen 34 is disposed at the upper position of each of the multiple C-shaped holes 33. The placement ring 31 in the placement component 3 can be placed in the inner cavity of the first limiting groove 13 and can also provide an installation base for the screen plate 32. Since there are multiple C-shaped holes 33 on one side of the inner cavity of the placement ring 31, and the multiple C-shaped holes 33 are distributed in a circumferential array, and the filter screen 34 is fixedly connected to the upper position of each of the multiple C-shaped holes 33, the placement ring 31 can provide support for the screen plate 32, thereby allowing the screen plate 32 to drain water. At the same time, the water can be drained through the C-shaped holes 33 to ensure the stability of water drainage. The filter screen 34 can block the pulp, thereby preventing the pulp from being discharged from the C-shaped holes 33 and preventing pulp loss.
[0020] During operation, when papermaking is required, the limiting component 1 is first placed in the preset position, and then the pressing component 2 is fixedly connected to the top surface of the limiting component 1. Since the placement component 3 is movably connected to the inner cavity of the limiting component 1, the limiting component 1 can limit and fix the placement component 3, thereby pressing the output end of the pressing component 2 against the top of the limiting component 1 to maintain the seal between the limiting component 1 and the pressing component 2. Then, through the pressing component 2, the worker can add pulp into the inner cavity of the pressing component 2, thereby allowing the placement component 3 to place the pulp. Then, through the limiting component 1, water in the pulp can be discharged, thereby evenly leaving the pulp in the inner cavity of the placement component 3. This allows the pressing component 2 to dewater the pulp in the inner cavity of the placement component 3, thereby enhancing the compactness and strength of the pulp.
[0021] The worktable 11 in the limiting assembly 1 can be placed in a preset position and also provides an installation base for the limiting cylinder 12. Since the top surface of the limiting cylinder 12 has a first limiting groove 13, and the inner cavity of the limiting cylinder 12 is movably connected to a top plate 14, while the bottom surface of the top plate 14 is fixedly connected to a first telescopic rod 15, the worktable 11 can provide support for the limiting cylinder 12. This allows the first limiting groove 13 to limit and fix the placement assembly 3, thereby improving the stability of the placement assembly 3. Then, through the first telescopic rod 15, the placement assembly 3 can be... While extending and retracting the output end of the first telescopic rod 15, the top plate 14 moves up and down, thereby lifting the placement component 3 and improving the stability of dehydration within the cavity of the placement component 3. A lifting plate 16 is movably connected to the outer side of the center of the bottom surface of the top plate 14, and a second telescopic rod 17 is fixedly connected to the bottom surface of the lifting plate 16. Three second telescopic rods 17 are fixedly connected, and a drain pipe 18 is embedded in one side of the limiting cylinder 12. Thus, while extending and retracting the output ends of the three second telescopic rods 17, the lifting plate 16 moves up and down. The lifting plate 16 can be adjusted so that when the top plate 14 lifts the placement component 3, the lifting plate 16 can be lowered, thereby draining the water generated during the dehydration of the placement component 3 through the drain pipe 18, thus improving convenience. A movable groove 110 is provided in the center of the top surface of the workbench 11, and lead screws 111 are rotatably connected to both sides of the inner cavity of the movable groove 110. A servo motor 112 is rotatably connected to one end of the lead screw 111, and a movable plate 113 is fixedly connected to the outside of the lead screw 111, thereby allowing the output end of the servo motor 112 to rotate. Simultaneously, the movement drives the lead screw 111 to rotate, thereby adjusting the position of the movable plate 113. This allows the movable plate 113 to move the limiting cylinder 12, facilitating the adjustment of the position of the limiting cylinder 12. Since the top surface of the limiting cylinder 12, located outside the first limiting groove 13, has a locking groove 19, and the locking groove 19 is connected to the pressing component 2, the pressing component 2 can be inserted into the inner cavity of the locking groove 19. This allows the locking groove 19 to limit the pressing component 2, thereby improving the sealing between the limiting cylinder 12 and the pressing component 2.
[0022] The gantry frame 21 in the holding assembly 2 can be fixedly connected to the top surface of the workbench 11 and provide an installation base for the two lifting cylinders 22. Since three third telescopic rods 23 are embedded in the top surface of each of the two lifting cylinders 22, and these three third telescopic rods 23 are arranged in a circular array, the workbench 11 can support the gantry frame 21. This allows the output end of the third telescopic rod 23 to extend and retract, simultaneously moving the lifting cylinders 22 up and down, thus adjusting their position and ensuring they fit snugly against the limiting cylinder 12. An inlet pipe 24 is embedded in the center of one side of the top surface of the gantry frame 21, and a telescopic pipe 25 is fixedly connected to the output end of the inlet pipe 24. The output end of the telescopic pipe 25 is connected to one of the lifting cylinders 22, allowing workers to add pulp into the inner cavity of the inlet pipe 24. The pulp in the inner cavity of the inlet pipe 24 is then added to one of the lifting cylinders 22 via the telescopic pipe 25. The inner cavity of each lifting cylinder 22 is designed to allow pulp to be added into the inner cavity of the placement component 3. Since the bottom surfaces of both lifting cylinders 22 are provided with second limiting grooves 26, and both lifting cylinders 22 have locking plates 27 fixedly connected to their bottom surfaces within the second limiting grooves 26, and these locking plates 27 are connected to locking grooves 19, the locking plates 27 can be inserted into the inner cavity of the locking grooves 19, thereby engaging the second limiting grooves 26 with the top surface of the placement component 3. This improves the sealing between the two lifting cylinders 22 and the limiting cylinders 12. A fourth telescopic rod 28 is embedded in the center of the top surface of the other lifting cylinder 22, and a pressure plate 29 is fixedly connected to the output end of the fourth telescopic rod 28. This allows the pressure plate 29 to move up and down while the output end of the fourth telescopic rod 28 extends and retracts, thus pressing the pulp in the inner cavity of the placement component 3. This allows the pressure plate 29 to dewater the pulp in the inner cavity of the placement component 3, thereby improving its compactness and strength.
[0023] The placement ring 31 in the placement component 3 can be placed in the inner cavity of the first limiting groove 13 and can also provide an installation base for the screen plate 32. Since there are multiple C-shaped holes 33 on one side of the inner cavity of the placement ring 31, and the multiple C-shaped holes 33 are distributed in a circumferential array, and the filter screen 34 is fixedly connected to the upper position of each of the multiple C-shaped holes 33, the placement ring 31 can provide support for the screen plate 32, thereby allowing the screen plate 32 to drain water. At the same time, the water can be drained through the C-shaped holes 33 to ensure the stability of water drainage. The filter screen 34 can block the pulp, thereby preventing the pulp from being discharged from the C-shaped holes 33 and preventing pulp loss.
[0024] In summary, this device can perform both papermaking and dewatering of pulp, thereby improving dewatering efficiency and consequently increasing work efficiency.
