Description

Technical Field

[0001] This application relates to the field of winding equipment, and more particularly to a winding device for the production of polyester fibers. Background Technology

[0002] Polyester fiber, also known as polyester fiber, is a common synthetic fiber. Its most prominent characteristics are excellent wrinkle resistance, abrasion resistance, and dimensional stability, making polyester fiber a crucial component in clothing manufacturing.

[0003] Chinese Patent No. CN222860847U discloses a winding device for polyester filament production, including a rectangular box. A winding motor is fixedly connected to the left side of the rear top of the rectangular box. A rotating shaft is fixedly sleeved at the other end of the output shaft of the winding motor. A winding roller is movably sleeved on the outer surface of the rotating shaft. A rectangular groove located to the right of the winding roller is opened on the top of the rectangular box.

[0004] During the use of the above technology, as the diameter of the polyester filaments wound on the winding roller increases, workers need to stop the machine to measure the diameter of the polyester filaments. However, the workers rely on observation to measure the diameter, which requires multiple measurements to ensure that the winding roller reaches the required diameter. This results in multiple machine stops for measurement, which greatly affects the processing efficiency of polyester filament winding and has obvious shortcomings. Utility Model Content

[0005] In order to improve the processing efficiency of polyester filament winding, this application provides a winding device for polyester fiber production.

[0006] The technical solution provided in this application for a winding device for polyester fiber production is as follows:

[0007] A winding device for polyester fiber production includes a processing table and a conveyor roller. The conveyor roller has two support frames, and a main shaft is rotatably mounted between the two support frames. A take-up roller for winding polyester filaments is coaxially sleeved on the main shaft. A fixed roller component for fixing the take-up roller is mounted on the main shaft. A vertical frame is mounted on the processing table, and a winding assembly for driving the main shaft to rotate is mounted on the vertical frame. A laser emitter electrically connected to a control system is mounted on the vertical frame, and a laser receiver electrically connected to the control system is mounted on the support frames. A fixing component for fixing the conveyor roller is mounted on the processing table. When the conveyor roller is fixed on the processing table, the main shaft is located between the laser emitter and the laser receiver. A guide component for guiding the polyester filaments to wind onto the take-up roller is mounted on the processing table.

[0008] By adopting the above technical solution, the worker first fixes the take-up roller to the main shaft using the fixed roller component, then pushes the roller conveyor close to the processing table, and then fixes the roller conveyor to the processing table using the fixing component. Then, the worker winds the polyester yarn onto the take-up roller using the yarn guide component. Then, the winding assembly drives the main shaft to rotate, and the rotating main shaft continuously winds the polyester yarn. During this process, the laser receiver on the support frame can always receive the laser signal emitted by the laser emitter on the upright frame until the diameter of the polyester yarn wound on the take-up roller continuously increases and blocks the laser signal emitted by the laser emitter. At this time, the control system stops driving the main shaft, and the worker can directly replace the roller conveyor. This process does not require repeated machine stops, which helps to improve the processing efficiency of polyester yarn winding.

[0009] Optionally, the fixed roller includes a positioning cone slidably sleeved at both ends of the main shaft. The diameter of the positioning cone gradually decreases along the direction from the end of the main shaft to the take-up roller. The end of the take-up roller abuts against the conical surface of the positioning cone. A positioning bolt is threaded onto the positioning cone, and the positioning bolt is used to abut against the circumferential outer wall of the main shaft.

[0010] By adopting the above technical solution, winding rollers with different inner diameters can be fixed between the conical surfaces of the two positioning cones. At the same time, by tightening or loosening the positioning bolts, it is convenient for workers to replace the winding rollers.

[0011] Optionally, the fixing component includes a connecting rod, both ends of which are provided with a fixing rod with a polygonal cross-section, and the processing table and the conveying roller are provided with fixing slots for the fixing rods to be inserted.

[0012] By adopting the above technical solution, when the roller conveyor approaches the processing table, the worker can quickly fix the roller conveyor on the processing table by using the connection between the fixing rods at both ends of the connecting rod and the fixing grooves on the processing table and the roller conveyor.

[0013] Optionally, the winding assembly includes a winding motor mounted on the upright and electrically connected to the control system. A transmission rod is coaxially mounted on the output shaft of the winding motor. A transmission tube, coaxial with the output shaft of the winding motor, is slidably sleeved on the transmission rod. The cross-section of the transmission rod and the inner diameter cross-section of the transmission tube are both polygonal. An insertion block is provided at the end of the main shaft. A slot for the insertion block is opened at the end of the transmission tube along the axial direction of the transmission tube. A sliding member for driving the transmission tube to slide is provided on the upright.

[0014] By adopting the above technical solution, after the conveyor roller is fixed, the sliding component drives the transmission tube to slide. The slot on the sliding transmission tube is inserted into the insert block at the end of the take-up roller. At this time, the control system starts the winding motor. The output shaft of the winding motor drives the main shaft to rotate through the transmission rod and transmission tube, thereby causing the main shaft to drive the take-up roller to rotate and wind the polyester yarn.

[0015] Optionally, the sliding component includes a sliding cylinder disposed on the upright and electrically connected to the control system. The piston rod of the sliding cylinder is provided with a C-shaped locking block. A transmission disc is coaxially disposed on the transmission tube, and the edge of the transmission disc is locked in the C-shaped concave side of the locking block.

[0016] By adopting the above technical solution, the control system starts the sliding cylinder, the piston rod of the sliding cylinder extends, and the piston rod of the sliding cylinder drives the locking block to approach the main shaft. The locking block drives the transmission tube to approach the main shaft through the transmission plate, so that the insert on the main shaft is inserted into the slot on the transmission tube.

[0017] Optionally, the guide element includes a tension frame mounted on the processing table, a lifting plate slidably mounted on the tension frame, a tension wheel rotatably mounted on the lifting plate, a lifting cylinder electrically connected to the control system mounted on the processing table, the lifting cylinder being located below the lifting plate, an adjusting plate mounted on the piston rod of the lifting cylinder, a pressure sensor electrically connected to the control system mounted on the adjusting plate, a compression spring supporting the sensing end of the pressure sensor and the lifting plate, a column mounted between the tension frame and the upright frame, a guide ring mounted on the column, and polyester yarn being wound onto the take-up roller in the order of passing around the tension wheel and through the guide ring.

[0018] By adopting the above technical solution, when the polyester filament is wound onto the take-up roller in the sequence of passing around the tension wheel and through the guide ring, if the tension on the polyester filament suddenly increases, the tension of the polyester filament will press down on the tension wheel. The tension wheel, through the lifting plate, squeezes the pressure spring below, causing the pressure spring to deform. The reaction force of the deformation of the pressure spring causes a change in the pressure value fed back by the pressure sensor. At this time, the control system activates the lifting cylinder. The piston rod of the lifting cylinder drives the pressure sensor to descend through the adjusting plate, thereby relieving the deformation of the pressure spring. At this time, the pressure spring recovers part of its deformation, and the tension on the polyester filament decreases. This ensures that the tension of the polyester filament wound on the take-up roller is always within a suitable range, reducing the possibility of the polyester filament getting tangled due to excessive tension during subsequent use.

[0019] Optionally, a cable tray is provided between the column and the frame, and a cable guide screw is rotatably mounted on the cable tray. The axis of the cable guide screw is parallel to the axis of the main shaft. A guide rail parallel to the axis of the cable guide screw is provided on the cable tray, and a cable guide block is threadedly connected to the cable guide screw. The cable guide block slides with the guide rail, and a cable guide ring for polyester yarn to pass through is provided on the cable guide block. A cable guide motor electrically connected to the control system is provided on the cable tray, and the cable guide screw is coaxially mounted on the output shaft of the cable guide motor.

[0020] By adopting the above technical solution, the control system starts the winding motor, and the output shaft of the winding motor drives the winding screw to rotate repeatedly. Under the restriction of the guide rail, the winding block drives the winding ring to slide back and forth along the axial direction of the winding screw, so that the polyester yarn can be evenly wound on the take-up roller.

[0021] Optionally, the conveyor is equipped with a wireless transmitter, and the laser receiver is electrically connected to the wireless transmitter.

[0022] By adopting the above technical solution, the impact of the conductor on the workers' working environment during the operation of the roller conveyor is reduced.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The worker first fixes the take-up roller to the main shaft using the fixed roller assembly, then pushes the roller conveyor close to the processing table. The roller conveyor is then fixed to the processing table using the fixing assembly. Next, the worker winds the polyester filament onto the take-up roller using the guide assembly. Then, the winding assembly drives the main shaft to rotate, and the rotating main shaft continuously winds the polyester filament. During this process, the laser receiver on the support frame can always receive the laser signal emitted by the laser emitter on the upright frame until the diameter of the polyester filament wound on the take-up roller continuously increases and blocks the laser signal emitted by the laser emitter. At this point, the control system stops driving the main shaft, and the worker can directly replace the roller conveyor. This process does not require repeated machine stops, which helps to improve the processing efficiency of polyester filament winding.

[0025] 2. After the conveyor roller is fixed, the sliding component drives the transmission tube to slide. The slot on the sliding transmission tube is inserted into the block at the end of the take-up roller. At this time, the control system starts the winding motor. The output shaft of the winding motor drives the main shaft to rotate through the transmission rod and transmission tube, thereby causing the main shaft to drive the take-up roller to rotate and wind the polyester yarn.

[0026] 3. As the polyester filament is wound onto the take-up roller in the sequence of passing over the tension wheel and through the guide ring, if the tension on the polyester filament suddenly increases, the tension will press down on the tension wheel. The tension wheel, through the lifting plate, squeezes the pressure spring below, causing the pressure spring to deform. The reaction force of the deformed pressure spring changes the pressure value fed back by the pressure sensor. At this time, the control system activates the lifting cylinder. The piston rod of the lifting cylinder drives the pressure sensor to descend through the adjusting plate, thereby relieving the deformation of the pressure spring. At this time, the pressure spring recovers part of its deformation, and the tension on the polyester filament decreases. This ensures that the tension of the polyester filament wound on the take-up roller is always within a suitable range, reducing the possibility of the polyester filament getting tangled due to excessive tension during subsequent use.

The processing table 2 and the roller carriage 3 are both provided with fixing slots 123 for the fixing rods 122 to be inserted. When the roller carriage 3 is fixed on the processing table 2, the spindle 5 is located between the laser emitter 10 and the laser receiver 11.

[0038] The worker first tightens the positioning bolts 72 to fix the take-up roller 6 to the main shaft 5, then pushes the roller conveyor 3 close to the upright frame 8, and then inserts one of the fixing rods 122 at both ends of the connecting rod 121 into the fixing groove 123 on the processing table 2 and the other fixing rod 122 into the fixing groove 123 on the roller conveyor 3, thereby completing the fixing of the roller conveyor 3.

A tension wheel 133 is rotatably connected to the top of the lifting plate 132. A lifting cylinder 134 electrically connected to the control system is bolted to the processing table 2.

[0042] Reference Figure 1 The cable laying block 17 is slidably engaged with the guide rail 16. A cable laying ring 18 for the polyester filament 1 to pass through is welded on the cable laying block 17. A cable laying motor 19 electrically connected to the control system is bolted to the cable laying frame 14. The cable laying screw 15 is coaxially welded to the output shaft of the cable laying motor 19. The polyester filament 1 is wound onto the take-up roller 6 in the order of passing around the tension wheel 133, passing through the guide ring 139, and passing through the cable laying ring 18.

[0043] The worker winds polyester filament 1 onto the take-up roller 6 in the following order: around the tension wheel 133, through the guide ring 139, and through the wire guide ring 18. The tension on the polyester filament 1 is pressed onto the tension wheel 133. At this time, the pressure sensor 136 feeds back a pressure value to the control system.

[0044] Then the control system starts the lifting cylinder 134. The piston rod of the lifting cylinder 134 extends, causing the adjusting plate 135 to drive the pressure sensor 136 to rise. At this time, the compression spring 137 is compressed, and the pressure value fed back by the pressure sensor 136 changes until it meets the tension value designed for the polyester yarn 1.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The upright frame 8 is provided with a winding assembly 9 that drives the main shaft 5 to rotate. The winding assembly 9 includes a winding motor 91 that is bolted to the upright frame 8 and electrically connected to the control system. A transmission rod 92 is coaxially welded to the output shaft of the winding motor 91. A transmission tube 93 that is coaxial with the output shaft of the winding motor 91 is slidably sleeved on the transmission rod 92.

[0046] Reference Figure 2 and Figure 3 The cross-section of the transmission rod 92 and the inner diameter cross-section of the transmission tube 93 are both polygonal. The end of the main shaft 5 is welded with a plug 94. The end of the transmission tube 93 and along the axial direction of the transmission tube 93 are provided with a slot 95 for the plug 94 to be inserted. The support frame 8 is provided with a sliding component 96 for driving the transmission tube 93 to slide.

[0047] Reference Figure 2 and Figure 3 The sliding component 96 includes a sliding cylinder 961 bolted to the upright 8 and electrically connected to the control system. A C-shaped locking block 962 is welded to the piston rod of the sliding cylinder 961. A transmission disc 963 is coaxially welded to the transmission tube 93. The edge of the transmission disc 963 is locked in the C-shaped concave side of the locking block 962.

[0048] The control system starts the sliding cylinder 961, the piston rod of the sliding cylinder 961 extends, and the piston rod of the sliding cylinder 961 drives the locking block 962 to approach the main shaft 5. The locking block 962 drives the transmission tube 93 to approach the main shaft 5 through the transmission disc 963, so that the insertion block 94 on the main shaft 5 is inserted into the slot 95 on the transmission tube 93.

[0049] Then the control system starts the winding motor 91. The output shaft of the winding motor 91 drives the transmission tube 93 to rotate through the transmission rod 92. The transmission tube 93 drives the main shaft 5 to rotate through the cooperation of the insert block 94 and the slot 95. The main shaft 5 drives the take-up roller 6 to rotate and wind the polyester yarn 1.

[0050] During the winding process of the take-up roller 6 winding the polyester filament 1, when the tension on the polyester filament 1 suddenly increases, the tension of the polyester filament 1 will press down the tension wheel 133. The tension wheel 133 will squeeze the pressure spring 137 below through the lifting plate 132. The pressure spring 137 will deform, and the reaction force of the deformation of the pressure spring 137 will change the pressure value fed back by the pressure sensor 136.

[0051] At this time, the control system starts the lifting cylinder 134, the piston rod of the lifting cylinder 134 retracts, and the piston rod of the lifting cylinder 134 drives the pressure sensor 136 to descend synchronously through the adjusting plate 135. At this time, the squeezing force on the compression spring 137 is relieved, the compression spring 137 recovers part of its deformation, the tension on the polyester filament 1 decreases, so that the tension of the polyester filament 1 wound on the take-up roller 6 is always within a suitable range.

[0052] The implementation principle of a winding device for polyester fiber production according to an embodiment of this application is as follows: the worker first tightens the positioning bolts 72 to fix the take-up roller 6 on the main shaft 5, then pushes the roller conveyor 3 close to the upright frame 8, and then inserts one of the fixing rods 122 at both ends of the connecting rod 121 into the fixing groove 123 on the processing table 2 and the other fixing rod 122 into the fixing groove 123 on the roller conveyor 3, thereby completing the fixing of the roller conveyor 3.

[0053] The worker winds polyester filament 1 onto the take-up roller 6 in the following order: around the tension wheel 133, through the guide ring 139, and through the wire guide ring 18. The tension on the polyester filament 1 is pressed onto the tension wheel 133. At this time, the pressure sensor 136 feeds back a pressure value to the control system.

[0054] Then the control system starts the lifting cylinder 134. The piston rod of the lifting cylinder 134 extends, causing the adjusting plate 135 to drive the pressure sensor 136 to rise. At this time, the compression spring 137 is compressed, and the pressure value fed back by the pressure sensor 136 changes until it meets the tension value designed for the polyester yarn 1.

[0055] The control system starts the sliding cylinder 961, the piston rod of the sliding cylinder 961 extends, and the piston rod of the sliding cylinder 961 drives the locking block 962 to approach the main shaft 5. The locking block 962 drives the transmission tube 93 to approach the main shaft 5 through the transmission disc 963, so that the insertion block 94 on the main shaft 5 is inserted into the slot 95 on the transmission tube 93.

[0056] Then the control system starts the winding motor 91. The output shaft of the winding motor 91 drives the transmission tube 93 to rotate through the transmission rod 92. The transmission tube 93 drives the main shaft 5 to rotate through the cooperation of the insert block 94 and the slot 95. The main shaft 5 drives the take-up roller 6 to rotate and wind the polyester yarn 1.

[0057] During the winding process of the take-up roller 6 winding the polyester filament 1, when the tension on the polyester filament 1 suddenly increases, the tension of the polyester filament 1 will press down the tension wheel 133. The tension wheel 133 will squeeze the pressure spring 137 below through the lifting plate 132. The pressure spring 137 will deform, and the reaction force of the deformation of the pressure spring 137 will change the pressure value fed back by the pressure sensor 136.

[0058] At this time, the control system starts the lifting cylinder 134, the piston rod of the lifting cylinder 134 retracts, and the piston rod of the lifting cylinder 134 drives the pressure sensor 136 to descend synchronously through the adjusting plate 135. At this time, the squeezing force on the compression spring 137 is relieved, the compression spring 137 recovers part of its deformation, the tension on the polyester filament 1 decreases, so that the tension of the polyester filament 1 wound on the take-up roller 6 is always within a suitable range.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
