Description

Technical Field

[0001] This utility model relates to the field of hemp yarn winding technology, and in particular to a hemp yarn winding device with a guiding structure. Background Technology

[0002] Hemp-viscose yarn is a blended yarn whose core is made of a blend of hemp fiber and viscose fiber in a certain proportion. It combines the characteristics of both fibers. After being spun out of the spinning machine, hemp-viscose yarn is initially in the form of loose yarn strips and cannot be used directly in subsequent processes. It must be wound into large packaged yarns, so a winding device is required. However, most existing hemp-viscose yarn winding devices still have problems that need to be solved.

[0003] Most existing flax yarn winding devices typically have a guiding structure to evenly wind the flax yarn onto the rollers. However, flax yarn has strong hygroscopicity, and its overall moisture regain fluctuates with changes in ambient temperature and humidity. It may absorb moisture from the workshop air, causing the yarn to thicken and lose elasticity, potentially leading to inconsistent winding density. It may also get stuck in the yarn guide holes or guide wheels, preventing the guiding structure and winding process from functioning properly. Therefore, it is necessary to design a flax yarn winding device with a guiding structure 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 winding device for hemp yarn with a guiding structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A winding device for hemp yarn with a guiding structure includes a first bearing housing. A rotating shaft is fixedly connected to the inner wall of the inner ring of the bearing on the first bearing housing. A limit rod is fixedly connected to one side of the rotating shaft. A winding roller is sleeved on the limit rod. A first synchronous pulley is fixedly connected to the outer wall of the rotating shaft at the end away from the limit rod. A synchronous belt is sleeved on the first synchronous pulley. A second synchronous pulley is provided at the end of the synchronous belt away from the first synchronous pulley. A reciprocating lead screw is fixedly connected to one side of the second synchronous pulley. A lead screw slide sleeve is sleeved on the reciprocating lead screw. A pin hole is provided radially on the inner circumference of the lead screw slide sleeve, and a crescent pin that mates with the reciprocating lead screw is provided in the pin hole. A moving block is fixedly connected to the outer wall of the lead screw slide sleeve. A guide block is fixedly connected to the bottom of the moving block. A blower is fixedly connected to the moving block at the side away from the winding roller. An air duct is fixedly connected to the input end of the blower. An air collector is fixedly connected to the input end of the air duct. The bottom of the air collector is fixedly connected to... The device is equipped with a heater, and a fan is fixedly connected to the bottom of the heater. Because it employs a technique of blowing hot air to dry the ramie yarn during the guiding process, it removes excess moisture caused by environmental humidity absorption, ensuring the normal operation of the guiding structure and winding process. This effectively solves the problem mentioned in the background art: most existing ramie yarn winding devices typically have a guiding structure to evenly wind the ramie yarn onto the rollers. However, ramie yarn has strong hygroscopicity, and its overall moisture regain fluctuates with changes in ambient temperature and humidity. After absorbing moisture, the yarn becomes thicker and loses elasticity, potentially leading to inconsistent winding density and even jamming on the yarn guide holes or guide wheels, causing the guiding structure and winding process to malfunction. Therefore, this device achieves the technical effects of ensuring continuous and stable operation of the guiding and winding system, reducing downtime, improving winding density uniformity, enhancing yarn quality, reducing dependence on ambient temperature and humidity, and increasing production adaptability.

[0006] As a further embodiment of this utility model, a bracket is fixedly connected to the bottom of the first bearing seat, and the bracket is fixedly connected to the heater.

[0007] As a further embodiment of this utility model, a guide rod is provided on the moving block, the moving block is slidably connected to the guide rod, and a second bearing seat is fixedly connected to both sides of the guide rod. The second bearing seat is fixedly connected to the bracket, and the inner wall of the inner ring of the bearing on the two second bearing seats is fixedly connected to the outer wall of the reciprocating lead screw.

[0008] As a further embodiment of this utility model, a third bearing seat is fixedly connected to the top of both ends of the bracket, and a tension roller is fixedly connected to the inner wall of the inner ring of the bearing on both third bearing seats.

[0009] As a further embodiment of this utility model, a fixed frame is fixedly connected to one side of the bracket, and a servo motor is fixedly connected to the fixed frame. The output end of the servo motor is connected to the rotating shaft through a coupling.

[0010] As a further embodiment of this utility model, the limiting rod is fixedly connected to a threaded rod on the side away from the rotating shaft, and a threaded sleeve is fitted on the threaded rod, the threaded sleeve being adapted to the threaded rod.

[0011] As a further embodiment of this utility model, a handle is fixedly connected to the outer wall of the threaded sleeve.

[0012] The beneficial effects of this utility model are as follows: By employing a technique of drying the ramie yarn with hot air during the guiding process, excess moisture generated by the yarn's absorption of moisture from the environment can be removed. This ensures the proper functioning of the guiding structure and winding process. It effectively solves the problem presented in the background section: most existing ramie yarn winding devices typically have a guiding structure that evenly winds the yarn onto rollers. However, ramie yarn is highly hygroscopic, and its overall moisture regain fluctuates with changes in ambient temperature and humidity. After absorbing moisture, the yarn becomes thicker and loses elasticity, potentially leading to inconsistent winding density and even jamming in the guide holes or guide wheels, thus hindering the guiding structure and winding process. This approach ensures the continuous and stable operation of the guiding and winding system, reduces downtime, improves winding density uniformity, enhances yarn quality, reduces dependence on ambient temperature and humidity, and increases production adaptability.

[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 1-4A winding device for hemp yarn with a guiding structure includes a first bearing seat 1. A rotating shaft 2 is fixedly connected to the inner wall of the inner ring of the bearing on the first bearing seat 1. A limit rod 201 is fixedly connected to one side of the rotating shaft 2. A winding roller 3 is sleeved on the limit rod 201. A first synchronous pulley 4 is fixedly connected to the outer wall of the rotating shaft 2 at the end away from the limit rod 201. A synchronous belt 5 is sleeved on the first synchronous pulley 4. A second synchronous pulley 6 is provided at the end of the synchronous belt 5 away from the first synchronous pulley 4. A second synchronous pulley 6 is fixedly connected to one side of the second synchronous pulley 6. A reciprocating lead screw 7 is provided, and a lead screw sleeve 8 is fitted on the reciprocating lead screw 7. A pin hole is provided radially on the inner circumference of the lead screw sleeve 8, and a crescent pin that mates with the reciprocating lead screw 7 is provided in the pin hole. A movable block 9 is fixedly connected to the outer wall of the lead screw sleeve 8, and a guide block 10 is fixedly connected to the bottom of the movable block 9. A blower 11 is fixedly connected to the side of the movable block 9 away from the winding roller 3. An air duct 12 is fixedly connected to the input end of the blower 11, and an air collector 13 is fixedly connected to the input end of the air duct 12. A heater 14 is fixedly connected to the bottom of component 13, and a fan 15 is fixedly connected to the bottom of heater 14. Because the technique of blowing hot air to dry the ramie yarn during the guiding process is adopted, the drying of the ramie yarn can remove excess moisture generated by environmental moisture absorption, ensuring the normal operation of the guiding structure and winding process. This effectively solves the problem mentioned in the background art: most existing ramie yarn winding devices typically have a guiding structure to evenly wind the ramie yarn onto the rollers. However, ramie yarn has strong hygroscopicity, and its overall moisture regain fluctuates with changes in ambient temperature and humidity. After absorbing moisture, the yarn becomes thicker and loses elasticity, potentially leading to inconsistent winding density and even jamming on the yarn guide hole or guide wheel, causing the guiding structure and winding process to malfunction. Therefore, this solution achieves the technical effects of ensuring continuous and stable operation of the guiding and winding system, reducing downtime, improving winding density uniformity, enhancing package yarn quality, reducing dependence on ambient temperature and humidity, and enhancing production adaptability.

[0017] In this embodiment, a bracket 16 is fixedly connected to the bottom of the first bearing seat 1, and the heater 14 is fixedly connected to the bracket 16.

[0018] In this embodiment, a guide rod 17 is provided on the movable block 9, and the movable block 9 is slidably connected to the guide rod 17. A second bearing seat 18 is fixedly connected to both sides of the guide rod 17. The second bearing seat 18 is fixedly connected to the bracket 16. The inner walls of the inner rings of the bearings on the two second bearing seats 18 are fixedly connected to the outer walls of the reciprocating screw 7. When the movable block 9 moves, it will move along the guide rod 17 to ensure the stability of the guide block 10 when it moves. The reciprocating movement of the guide block 10 guides the hemp yarn, so that the hemp yarn is evenly wound on the winding roller 3.

[0019] In this embodiment, the top of both ends of the bracket 16 are fixedly connected to the third bearing seat 19, and the inner wall of the inner ring of the bearing on the two third bearing seats 19 is fixedly connected to the tension roller 20. The hemp yarn is tensioned by the tension roller 20, and the hemp yarn is wrapped around the top of the tension roller 20, placed in the guide block 10, and finally wound on the winding roller 3.

[0020] In this embodiment, a fixed frame 21 is fixedly connected to one side of the bracket 16, and a servo motor 22 is fixedly connected to the fixed frame 21. The output end of the servo motor 22 is connected to the rotating shaft 2 through a coupling.

[0021] In this embodiment, a threaded rod 23 is fixedly connected to the limiting rod 201 on the side away from the rotating shaft 2. A threaded sleeve 24 is fitted on the threaded rod 23. The threaded sleeve 24 is adapted to the threaded rod 23. By screwing the threaded sleeve 24 onto the threaded rod 23, the position of the winding roller 3 is restricted, so that the winding roller 3 is stably fitted on the limiting rod 201, thereby ensuring that the winding can be carried out stably.

[0022] In this embodiment, a handle is fixedly connected to the outer wall of the threaded sleeve 24.

[0023] Working principle: In use, the winding roller 3 is placed on the limiting rod 201. The winding roller 3 and the limiting rod 201 are equipped with matching locking blocks and slots, ensuring that the rotation of the limiting rod 201 drives the winding roller 3 to rotate for winding. Then, the threaded sleeve 24 is placed on the threaded rod 23. Tightening the threaded sleeve 24 moves it closer to the winding roller 3, thus securing the winding roller 3. The hemp yarn is then passed around the top of the tension roller 20 and placed at the bottom of the guide block 10, finally winding onto the winding roller 3. It is powered by an external power supply and controlled by an external PLC. The device starts the servo motor 22, fan 15, and heater 14. The output of the servo motor 22 rotates, driving the coupling to rotate. The coupling drives the rotating shaft 2 to rotate, which in turn drives the limit rod 201 to rotate. The limit rod 201 drives the winding roller 3 to rotate for winding. When the rotating shaft 2 rotates, it also drives the first synchronous pulley 4 to rotate. The first synchronous pulley 4 drives the synchronous belt 5 to rotate, which in turn drives the second synchronous pulley 6 to rotate. The second synchronous pulley 6 drives the reciprocating lead screw 7 to rotate, which in turn drives the lead screw sleeve 8 to move back and forth. The lead screw sleeve 8 drives the moving block 9 to move along the guide rod 17. The movement of block 9 also drives the movement of guide block 10, which in turn drives the hemp yarn to move back and forth, ensuring that the hemp yarn is evenly wound onto the winding roller 3. During the winding process, heater 14 operates, and its internal heater heats up. Fan 15 blows air onto heater 14, which heats the air. The hot air is then transported through air collector hood 13 and air duct 12 to air blower 11, and finally sprayed out through air blower 11 to dry the hemp yarn. This removes excess moisture from the hemp yarn caused by moisture absorption from the environment, keeping the yarn diameter within a relatively uniform range and preventing it from becoming thicker due to moisture absorption. When the yarn thickness is uniform, even with uneven winding or density, the winding thickness of each loop of yarn is uniform under the same tension. This reduces the overall density difference of the final winding bobbin, minimizing the "loose on one side and tight on the other" situation. The elastic recovery rate of the yarn is improved after drying, allowing it to better adapt to tension fluctuations during high-speed winding and reducing "hard breakage" caused by insufficient elasticity. It also reduces dependence on ambient temperature and humidity, enhancing winding stability. After winding is complete, turn off the servo motor 22, heater 14, and fan 15, remove the threaded sleeve 24, and remove the winding roller 3 from the limit rod 201.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
