Description

Technical Field

[0001] This utility model relates to the field of wet spinning flax yarn production technology, and in particular to a guiding device for wet spinning flax yarn production. Background Technology

[0002] Wet-spun flax yarn is a mainstream production process for flax yarn. The core technology involves adding water as a key medium during the spinning process to improve the spinning performance of flax fibers and enhance yarn quality. Wet-spun flax yarn production is generally accompanied by guiding devices to solve the problems of difficult tension control, easy damage, and easy deviation of wet yarn. This ensures that the yarn can be stably and without damage transported from spinning to subsequent processes, which is crucial for connecting various production links. However, most guiding devices used in the current technology for wet-spun flax yarn production still have problems that need to be solved.

[0003] In most existing guiding devices for wet-spun flax yarn production, fine fibers easily detach from the surface of the wet-spun flax yarn during the process. If these fibers remain in the guide wheel groove, they can cause problems such as pilling and snagging on the subsequent yarn surface. In severe cases, they can even form knots, directly affecting the smoothness and strength of the final fabric. If the accumulation of fibers causes the shape of the wheel groove to change, it can cause the yarn to deviate from the preset path during transport. Therefore, it is urgent to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a guiding device for wet spinning of flax yarn.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A guiding device for wet-spun flax yarn production includes a mounting frame. First bearing seats are fixedly connected to the top of both ends of the mounting frame. A common rotating shaft is fixedly connected to the inner walls of the inner rings of the bearings on the two first bearing seats. A plurality of equally spaced guide wheels are fixedly connected to the outer wall of the rotating shaft. A common support frame is fixedly connected to the top of both ends of the mounting frame. A lifting plate is provided at the top of the support frame. A plurality of equally spaced square grooves are formed at both ends of the lifting plate. Square blocks are arranged within the square grooves. The square blocks are slidably connected to the lifting plate. A movable block is fixedly connected to the bottom of each square block. A pin is fixedly connected to one side of the top. Several U-shaped blocks are provided on the top of the lifting plate. A soft brush is fixedly connected to the top of each U-shaped block. Slots are provided on both sides of each U-shaped block, and these slots are adapted to the pin. A triangular block is fixedly connected to the bottom of the moving block. A fixing frame is provided at the bottom of the triangular block, and a roller is rotatably connected to the fixing frame. The roller is located on the inclined surface of the triangular block. A support frame is fixedly connected to the fixing frame. Two limiting rods are fixedly connected to one side of the moving block. The two limiting rods at the same end are fitted with the same limiting block. The limiting rods are slidably connected to the limiting block. The positioning block is fixedly connected to the lifting plate, and the limiting rod is fitted with a return spring. Due to the use of a soft brush to clean the guide wheel and the technical means of fixing the U-shaped block when it rises and releasing it when it descends, the soft brush can remove fibers adhering to the guide wheel groove. When the U-shaped block rises, the pin can be inserted into the slot to fix it; when it descends, the pin can be removed from the slot to release it. This facilitates the removal and cleaning of the soft brush, effectively solving the problem of guide devices used in wet-spinning flax yarn production in most existing technologies. During the process of guiding wet-spun flax yarn, fine fibers easily detach from the surface of the wet-spun flax yarn. If these fibers remain in the guide wheel groove, it will cause problems such as pilling and snagging on the surface of the subsequent yarn. In severe cases, it will also form cotton knots, directly affecting the smoothness and strength of the final fabric. If the accumulation of fibers causes the shape of the wheel groove to change, it will cause the yarn to deviate from the preset path during transportation. This achieves the technical effects of making it easy to clean the residual fibers in the guide wheel groove, avoiding the accumulation of fibers in the guide wheel groove, ensuring that the yarn is always transported along a fixed path, reducing the risk of yarn breakage, maintaining production continuity, facilitating disassembly and maintenance, and reducing equipment downtime.

[0006] As a further embodiment of this utility model, four guide rods are provided on the support frame, the guide rods are slidably connected to the support frame, and all four guide rods are fixedly connected to the lifting plate.

[0007] As a further embodiment of this utility model, two second bearing seats are fixedly connected to the top of both ends of the mounting frame, and the inner walls of the inner rings of the bearings on the two second bearing seats on the same side are fixedly connected to the same tensioning roller.

[0008] As a further embodiment of this utility model, a movable cylinder is fixedly connected to the bottom of the lifting plate, a threaded sleeve is fixedly connected to the inner wall of the movable cylinder, a threaded rod is threaded through the threaded sleeve, the threaded sleeve and the threaded rod are adapted to each other, a servo motor is provided at the bottom of the threaded rod, the output end of the servo motor is connected to the bottom of the threaded rod through a coupling, and a cylinder is slidably connected to the outer wall of the movable cylinder, and the cylinder is fixedly connected to the top of the support frame.

[0009] As a further embodiment of this utility model, a mounting plate is fixedly connected to the mounting surface of the servo motor, and a support frame is fixedly connected to the mounting plate.

[0010] As a further embodiment of this utility model, a motor box is fixedly connected to the bottom of the mounting plate, and the servo motor is disposed inside the motor box.

[0011] As a further embodiment of this utility model, positioning grooves are provided at both ends of the U-shaped block, and positioning rods are provided in the positioning grooves of the U-shaped block, with several positioning rods fixedly connected to the top of the lifting plate.

[0012] The beneficial effects of this utility model are as follows: Because it employs a soft brush to clean the guide wheel and a technique that allows the U-shaped block to be fixed when it rises and released when it descends, the soft brush can remove fibers adhering to the guide wheel groove. The rising of the U-shaped block allows the pin to be inserted into the slot to fix it, and the descending of the U-shaped block allows the pin to be removed from the slot to release it. This facilitates the removal and cleaning of the soft brush, effectively solving the problem mentioned in the background art regarding the guiding devices used in most existing wet-spun flax yarn production. During the process, fine fibers easily detach from the surface of wet-spun flax yarn. If these fibers remain in the guide wheel groove, they can cause problems such as pilling and snagging on the surface of subsequent yarns. In severe cases, they can even form knots, directly affecting the smoothness and strength of the final fabric. If fiber accumulation causes the shape of the wheel groove to change, it can cause the yarn to deviate from the preset path during transport. This process facilitates the cleaning of residual fibers in the guide wheel groove, avoids fiber accumulation in the guide wheel groove, ensures that the yarn is always transported along a fixed path, reduces the risk of yarn breakage, maintains production continuity, facilitates disassembly and maintenance, and reduces equipment downtime.

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-7A guiding device for wet-spun flax yarn production includes a mounting frame 1. First bearing seats 2 are fixedly connected to the top of both ends of the mounting frame 1. A common rotating shaft 3 is fixedly connected to the inner wall of the inner ring of the bearings on the two first bearing seats 2. A plurality of guide wheels 4, evenly distributed, are fixedly connected to the outer wall of the rotating shaft 3. A common support frame 5 is fixedly connected to the top of both ends of the mounting frame 1. A lifting plate 7 is provided at the top of the support frame 5. A plurality of equally distributed square grooves 8 are opened at both ends of the lifting plate 7. Square blocks 10 are arranged in the square grooves 8. The square blocks 10 are slidably connected to the lifting plate 7. A movable block 9 is fixedly connected to the bottom of the square blocks 10. The top of the square blocks 10... A pin 11 is fixedly connected to one side. Several U-shaped blocks 12 are provided on the top of the lifting plate 7. A soft brush 13 is fixedly connected to the top of the U-shaped block 12. Slots 14 are provided on both sides of the U-shaped block 12. The slots 14 are adapted to the pin 11. A triangular block 15 is fixedly connected to the bottom of the moving block 9. A fixing frame 16 is provided at the bottom of the triangular block 15. A roller 17 is rotatably connected to the fixing frame 16. The roller 17 is located on the inclined surface of the triangular block 15. The fixing frame 16 is fixedly connected to the support frame 5. Two limiting rods 19 are fixedly connected to one side of the moving block 9. The two limiting rods 19 at the same end are fitted with the same limiting block 18. The limiting rods 19 slide... A movable connecting limit block 18 is fixedly connected to a lifting plate 7. A limit rod 19 is fitted with a return spring 20. Due to the use of a soft brush to clean the guide wheel and the technical means of fixing the U-shaped block when it rises and releasing it when it falls, the soft brush can clean the fibers attached to the guide wheel groove. When the U-shaped block rises, the pin can be inserted into the slot to fix it; when the U-shaped block falls, the pin can be removed from the slot to release it. This facilitates the removal and cleaning of the soft brush, effectively solving most of the problems in the prior art regarding wet spinning of flax. In the process of guiding wet-spun flax yarn, the guiding device used in yarn production is prone to shedding fine fibers from the surface of the wet-spun flax yarn. If these fibers remain in the guide wheel groove, they can cause problems such as pilling and snagging on the surface of subsequent yarns. In severe cases, they can even form knots, directly affecting the smoothness and strength of the final fabric. If the accumulation of fibers causes the shape of the wheel groove to change, it can cause the yarn to deviate from the preset path during transport. This device facilitates the cleaning of residual fibers in the guide wheel groove, avoids fiber accumulation in the guide wheel groove, ensures that the yarn is always transported along a fixed path, reduces the risk of yarn breakage, maintains production continuity, facilitates disassembly and maintenance, and reduces equipment downtime.

[0017] In this embodiment, four guide rods 6 are provided on the support frame 5. The guide rods 6 are slidably connected to the support frame 5. All four guide rods 6 are fixedly connected to the lifting plate 7. When the lifting plate 7 moves, it will drive the guide rods 6 to move along the support frame 5, thereby ensuring the stability of the lifting plate 7 when it moves.

[0018] In this embodiment, two second bearing seats 21 are fixedly connected to the top of both ends of the mounting frame 1, and the inner walls of the inner rings of the bearings on the two second bearing seats 21 on the same side are fixedly connected to the same tensioning roller 22.

[0019] In this embodiment, a movable cylinder 23 is fixedly connected to the bottom of the lifting plate 7, and a threaded sleeve 24 is fixedly connected to the inner wall of the movable cylinder 23. A threaded rod 25 is threaded through the threaded sleeve 24, and the threaded sleeve 24 and the threaded rod 25 are adapted to each other. A servo motor 26 is provided at the bottom of the threaded rod 25, and the output end of the servo motor 26 is connected to the bottom of the threaded rod 25 through a coupling. A cylinder 30 is slidably connected to the outer wall of the movable cylinder 23, and the cylinder 30 is fixedly connected to the top of the support frame 5. The servo motor 26 is electrically connected to the external PLC controller through wires. By rotating the threaded rod 25 to adjust the height of the threaded sleeve 24, the height of the movable cylinder 23 is adjusted, thereby adjusting the height of the lifting plate 7. This also allows the height of the soft brush 13 to be adjusted so that the soft brush 13 makes more comprehensive contact with the guide groove of the guide wheel 4.

[0020] In this embodiment, a mounting plate 27 is fixedly connected to the mounting surface of the servo motor 26, and the mounting plate 27 is fixedly connected to the support frame 5.

[0021] In this embodiment, a motor box 28 is fixedly connected to the bottom of the mounting plate 27, and the servo motor 26 is set inside the motor box 28. The servo motor 26 is protected by the motor box 28, and the bottom of the motor box 28 is provided with heat dissipation holes to ensure heat dissipation.

[0022] In this embodiment, positioning grooves are provided at both ends of the U-shaped block 12, and positioning rods 29 are provided in the positioning grooves of the U-shaped block 12. Several positioning rods 29 are fixedly connected to the top of the lifting plate 7. The positioning rods 29 and the positioning grooves on the U-shaped block 12 cooperate to position the U-shaped block 12 and the lifting plate 7, so as to ensure that the installation position of the U-shaped block 12 is accurate.

[0023] Working Principle: During use, the wet-spun linen yarn is arranged according to the path shown in the attached diagram of the instruction manual, mounting frame 1. When the traction device pulls the wet-spun linen yarn, the guide wheel 4 guides it, ensuring a neat arrangement. As the guide wheel 4 rotates, the soft brush 13 cleans away any fine fibers that have fallen off the surface of the wet-spun linen yarn during transport, preventing issues such as pilling and snagging on the yarn surface. This ensures the smoothness and strength of the final fabric and prevents fiber accumulation from altering the shape of the guide wheel 4's guide groove, allowing the yarn to maintain its preset path during transport. After a period of use, some fibers will also adhere to the surface of the soft brush 13. To ensure cleaning effectiveness, the soft brush 13 needs to be cleaned or replaced. The servo motor 26 is started via the external PLC controller, causing its output to rotate. This rotates the threaded rod 25, which in turn moves the threaded sleeve 24, which in turn moves the moving cylinder 23. The moving cylinder 23 moves the lifting plate 7, which in turn moves the limit block 18 downwards. The limit block 18 moves the limit rod 19, which in turn moves the moving block 9. The moving block 9 moves the square block 10, which in turn moves the pin 11. The pin 11 then moves the U-shaped block 12 downwards. The U-shaped block 12 then moves the soft brush 13 downwards, away from the guide wheel 4. The downward movement of the moving block 9 also moves the triangular... As block 15 descends, the inclined surface of triangular block 15 contacts roller 17. Restricted by roller 17, if two triangular blocks 15 at the same end continue to descend, they will move away from each other. This allows square block 10 to move away from U-shaped block 12. Square block 10 will then move pin 11 out of slot 14. During this process, moving block 9 will move limit rod 19, which will compress return spring 20, causing it to contract. Limit rod 19 will move along limit block 18, ensuring stability during the movement of moving block 9. After pin 11 is removed from slot 14, U-shaped block 12 can be removed from positioning rod 29, allowing soft brush 13 to be detached for deep cleaning or further cleaning. During replacement and assembly, lower the lifting plate 7 to its lowest position, place the U-shaped block 12 on the positioning rod 29 for positioning, and then rotate the output end of the servo motor 26 in the opposite direction to raise the lifting plate 7. When the triangular block 15 disengages from the roller 17, the contracted return spring 20 will extend, allowing the two limit rods 19 to move closer to each other, which in turn allows the moving block 9 to move, bringing the two pins 11 closer to each other until they are inserted into the slot 14. This restricts the position between the U-shaped block 12 and the lifting plate 7, thus fixing the U-shaped block 12 and allowing the soft brush 13 to be installed. Continue to rotate the output end of the servo motor 26 to adjust the height of the soft brush 13 so that the soft brush 13 can fully contact the guide wheel 4 to ensure the cleaning effect on the guide wheel 4.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
