Description

Technical Field

[0001] This invention relates to the field of cotton yarn processing technology, specifically to a cotton yarn sliver cutting device for cotton yarn processing. Background Technology

[0002] In the cotton yarn processing, cotton sliver cutting is a crucial step. Specifically, the cutting device first uses a transverse movement device and a guiding device to ensure that the cotton sliver is wound more evenly onto the bobbin. Once the bobbin is fully wound with cotton sliver, the cutting device automatically brings the cotton sliver to the space where the cutting device is located. At this point, the roller pressing device compacts the cutting area of ​​the cotton sliver to reduce the occurrence of some cotton fibers falling off during the cutting process. After compaction, the cutting device performs the cutting operation, neatly cutting the cotton sliver.

[0003] During the above process, the entire cotton yarn processing process must be stopped during the cutting process to avoid cotton yarn accumulation and misalignment during the compaction process, thereby ensuring the quality of the cutting.

[0004] A search revealed that Chinese patent application CN221028823U discloses a cotton yarn cutting device. While this device avoids wrinkling of the cotton yarn, thus improving the cutting quality and efficiency, it also requires stopping the cotton yarn processing, affecting the overall efficiency. Furthermore, the machine experiences significant start-up and shutdown losses, especially in large-scale factory production. If the cotton yarn is being gathered and cut simultaneously, the cut surface will be uneven, affecting both the cutting effect and the quality of the cotton yarn. Additionally, each step of the cutting process requires a series of control elements, increasing costs and complicating the process. The device cannot be automated through mechanical mechanisms, resulting in low reliability and durability. Summary of the Invention

[0009] As a further embodiment of the present invention: a tension spring is fixedly connected between the slide and the side wall of the slide groove; the outer surface of the gathering roller is tangent to the top surface of the cutting table; the cutter is located above the pressure strip; the lifting plate is driven by an electric push rod; the end of the transmission chain is fixedly connected to the end of the gathering roller; and the auxiliary block is fixedly connected to the bottom surface of the cutting table.

[0010] As a further aspect of the present invention: multiple guide grooves, sliders, and inserts are provided, and the multiple guide grooves, sliders, and inserts are evenly distributed about the central axis of the transmission shaft.

[0011] As a further embodiment of the present invention: the rotating shaft is rotatably sleeved with the first connecting block, the driven sprocket is rotatably sleeved with the second connecting block, the connecting block is slidably sleeved with the cutting table, and the insert strip is fitted and connected with the groove.

[0012] As a further embodiment of the present invention: the connecting rod is slidably connected to the end face of the fixed roller, the connecting rod is slidably connected to the end face of the sliding roller, and the transmission chain, the driving sprocket, and the driven sprocket have the same diameter.

[0013] As a further aspect of the present invention: a first sealed cavity is provided in the side wall of the sliding roller, one end of a first piston rod is slidably sleeved in the first sealed cavity, and a meshing block is fixedly connected to the other end of the first piston rod; a second sealed cavity is provided in the bottom wall of the slide, a second piston rod is slidably sleeved on the top surface of the second sealed cavity, and an air guide pipe is connected between the bottom end of the first sealed cavity and the bottom end of the second sealed cavity.

[0014] As a further aspect of the present invention: two first sealed cavities and two meshing blocks are provided, and the bottom ends of the two first sealed cavities are connected, and the meshing block is sleeved with the sliding roller.

[0015] As a further embodiment of the present invention: the meshing block is meshed with the lead screw, the air guide tube is fixedly sleeved with the slide, and the second piston rod is located directly below the cutter.

[0016] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows:

[0017] This invention uses insert strips to drive the rotation of the driving roller, which in turn causes the first track on the driving roller to drive the rotation of the driven roller. This, in turn, causes the driven roller to drive the driving sprocket to rotate via a shaft, resulting in movement of the chain on the driving sprocket. This chain, in turn, causes the carriage to move along the slide groove via a connecting block. Since the transmission chain, driving sprocket, and driven sprocket have the same diameter, the chain's moving speed is the same as the transmission chain's moving speed. Furthermore, this makes the carriage's translational speed the same as the cotton yarn's moving speed. At this point, the electric push rod is activated, causing the lifting plate to descend, thus raising the carriage... The pressure bar on the plate descends and squeezes the cotton yarn strip. Because the translational speed of the carriage is the same as the moving speed of the cotton yarn strip, the pressure bar and the cotton yarn strip remain relatively stationary, preventing the cotton yarn strip from being misaligned and piled up after being squeezed by the pressure bar. As the lifting plate continues to descend, the compression spring on the pressure bar contracts until the cutter on the lifting plate cuts the cotton yarn strip, achieving the purpose of cutting the cotton yarn strip. There is no need to stop the cotton yarn processing process, which improves the efficiency of cotton yarn processing, avoids losses when the machine is started and stopped, and at the same time ensures the neatness of the cut surface of the cotton yarn strip, improves the cutting effect of the cotton yarn strip, and avoids affecting the quality of the cotton yarn strip.

[0018] This invention releases the engagement between the meshing block and the lead screw by pressing the second piston rod on the slide, indirectly releasing the fixation between the sliding roller and the lead screw. Then, the sliding roller is moved to a specified distance from the end of the lead screw, and the slip ring moving with the sliding roller reaches a specified position. The motor on the fixed fixture is then started, causing the motor to drive the transmission chain through the transmission shaft. During the rotation of the transmission shaft, the transmission shaft drives the slider to rotate through the guide groove, causing the slip ring on the slider to rotate. This causes the fixed roller on the slip ring to rotate, and the fixed roller drives the sliding roller to rotate through the second track. The sliding roller is engaged with the lead screw through the meshing block, while the lead screw remains stationary. This causes the rotating sliding roller to move along the lead screw... The sliding roller moves until it reaches the end of the lead screw. At this point, the slip ring, which moves with the sliding roller, inserts the insert into the groove of the drive roller, thus enabling the cutting of the cotton yarn. In summary, for the sliding roller to reach the end of the lead screw, the drive shaft needs to rotate a specific number of times. When the distance between the sliding roller and the end of the lead screw is set, the number of rotations of the drive shaft is also accurately determined. Since the number of rotations of the drive shaft is the same as that of the take-up roller, the subsequent cutting operation can be automatically performed when the cotton yarn is gathered to a specific length, achieving autonomous cutting without the need for a series of control elements to operate step by step. This not only reduces cost input but also simplifies the processing. The entire cutting process can be completed through a mechanical mechanism, improving the reliability and durability of the device.

[0019] This invention uses the cutting blade to press down on the second piston rod below it, repeating the above principle, so that the slip ring is reset by the return spring, and the slide is reset by the return spring. This allows the device to cycle through the above process. At the same time, the traction and cutting of the cotton yarn are controlled by an electric motor. The faster the traction speed of the cotton yarn, the faster the movement speed of the slide will be. The cutting blade, the pressing strip and the cotton yarn can always be kept relatively stationary without the need for additional adjustment devices, further simplifying the operation process.

[0030] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1: Please refer to Figures 2-6This invention provides a technical solution: a cotton yarn sliver cutting device for cotton yarn processing. A guide groove 20 is formed on the outer surface of a drive shaft 15, and a slip ring 21 is fitted onto the drive shaft 15. A slider 22 is fixedly connected to the inner surface of the slip ring 21, and the slider 22 slidably engages with the guide groove 20. An insert 23 is fixedly connected to the end face of the slip ring 21. A drive roller 24 is rotatably fitted onto the outer surface of the drive shaft 15. A groove 25 is formed through the drive roller 24, and one end of a first track 26 is fitted onto the drive roller 24. A driven roller 27 is fitted onto the other end of the first track 26. One end of a rotating shaft 28 is fixedly connected to the central axis of the driven roller 27, and a drive sprocket 29 is fixedly connected to the other end of the rotating shaft 28. One end of a chain 30 is meshed on wheel 29, and the other end of the chain 30 is meshed on driven sprocket 31. A connecting block 32 is rotatably connected to the side wall of chain 30. The connecting block 32 is fixed to the bottom surface of slide 8. A fixed roller 33 is fixed to the end face of slip ring 21. The fixed roller 33 is slidably connected to drive shaft 15. One end of second track 36 is sleeved on fixed roller 33. A sliding roller 35 is sleeved on the other end of second track 36. A lead screw 34 is sleeved on the central axis of sliding roller 35. The lead screw 34 is fixed to the side wall of fixed fixture 13. A connecting rod 37 is provided between fixed roller 33 and sliding roller 35. A return spring 38 is fixed between connecting rod 37 and side wall of fixed fixture 13.

[0032] Please see Figure 6 Multiple guide grooves 20, sliders 22 and inserts 23 are provided, and the multiple guide grooves 20, multiple sliders 22 and multiple inserts 23 are evenly distributed about the central axis of the drive shaft 15.

[0033] Please see Figures 4-6 The rotating shaft 28 is rotatably sleeved with the first connecting block 18, the driven sprocket 31 is rotatably sleeved with the second connecting block 19, the connecting block 32 is slidably sleeved with the cutting table 6, and the insert strip 23 is fitted and connected with the insert groove 25.

[0034] Please see Figure 5 and Figure 6 The connecting rod 37 is slidably connected to the end face of the fixed roller 33, and the connecting rod 37 is slidably connected to the end face of the sliding roller 35. The transmission chain 16, the driving sprocket 29 and the driven sprocket 31 have the same diameter.

[0035] Specifically, during the insertion of the insert strip 23 into the groove 25, the rotation of the slip ring 21 drives the rotation of the drive roller 24 via the insert strip 23, causing the first track 26 on the drive roller 24 to drive the rotation of the driven roller 27. This, in turn, causes the driven roller 27 to drive the drive sprocket 29 to rotate via the shaft 28, resulting in the movement of the chain 30 on the drive sprocket 29. This, in turn, causes the chain 30 to drive the carriage 8 to translate along the slide groove 7 via the connecting block 32. Since the transmission chain 16, the drive sprocket 29, and the driven sprocket 31 have the same diameter, the moving speed of the chain 30 is the same as the moving speed of the transmission chain 16. This further ensures that the translational speed of the carriage 8 is the same as the moving speed of the cotton yarn strip. At this point, the operation can be restarted. The electric push rod causes the lifting plate 9 to descend, which in turn causes the pressure bar 10 on the lifting plate 9 to descend and compress the cotton yarn strip. Because the translational speed of the slide 8 is the same as the moving speed of the cotton yarn strip, the pressure bar 10 and the cotton yarn strip remain relatively stationary, preventing the cotton yarn strip from being misaligned and piled up after being compressed by the pressure bar 10. As the lifting plate 9 continues to descend, the compression spring 11 on the pressure bar 10 contracts until the cutter 12 on the lifting plate 9 cuts the cotton yarn strip, achieving the purpose of cutting the cotton yarn strip. There is no need to stop the cotton yarn processing process, which improves the efficiency of cotton yarn processing, avoids losses when the machine starts and stops, and ensures the neatness of the cut surface of the cotton yarn strip, improving the cutting effect of the cotton yarn strip and avoiding affecting the quality of the cotton yarn strip.

[0036] Example 2: Please refer to Figure 1 , Figure 3 , Figure 8 and Figure 9 The present invention provides a technical solution: a cotton yarn sliver cutting device for cotton yarn processing, wherein a first sealed cavity 39 is provided in the side wall of the sliding roller 35, one end of a first piston rod 40 is slidably sleeved in the first sealed cavity 39, and the other end of the first piston rod 40 is fixedly connected to a meshing block 41; a second sealed cavity 43 is provided in the bottom wall of the slide 8, a second piston rod 44 is slidably sleeved on the top surface of the second sealed cavity 43, and an air guide pipe 42 is connected between the bottom end of the first sealed cavity 39 and the bottom end of the second sealed cavity 43.

[0037] Please see Figure 3 , Figure 8 and Figure 9 There are two first sealed cavities 39 and two meshing blocks 41, and the bottom ends of the two first sealed cavities 39 are connected. The meshing block 41 is sleeved with the sliding roller 35.

[0038] Please see Figure 6 and Figure 9 The meshing block 41 is engaged with the lead screw 34, the air guide tube 42 is fixedly sleeved with the slide 8, and the second piston rod 44 is located directly below the cutter 12.

[0039] Specifically, during the winding process of the cotton yarn strip, the cotton yarn strip generated by the processing device 2 is passed through the bottom end of the guide roller 4 and wound onto the winding roller 5, so that the cotton yarn strip is parallel to the top surface of the cutting table 6. At this time, the second piston rod 44 on the slide 8 is pressed, causing the second piston rod 44 to compress the air in the second sealed chamber 43, thereby increasing the air pressure at the bottom end of the first sealed chamber 39 connected by the air guide pipe 42. This causes the first piston rod 40 in the first sealed chamber 39 to rise, thereby causing the first piston rod 40 to drive the meshing block 41 to rise, thus disengaging the meshing connection between the meshing block 41 and the lead screw 34, indirectly releasing the slide. With the movable roller 35 fixed to the lead screw 34, the sliding roller 35 is then moved to make the distance between the sliding roller 35 and the end of the lead screw 34 reach the specified length. At the same time, the slip ring 21, which moves with the sliding roller 35, reaches the specified position. Then, the compression of the second piston rod 44 is released, causing the meshing block 41 to reset. The motor 14 on the fixed fixture 13 is then started, causing the motor 14 to drive the transmission chain 16 to rotate through the transmission shaft 15. This causes the transmission chain 16 to drive the take-up roller 5 to rotate, so that the take-up roller 5 continues to wind the cotton yarn. During the rotation of the transmission shaft 15, the transmission shaft 15 passes through the guide groove 20. The slider 22 rotates, causing the slip ring 21 on the slider 22 to rotate, which in turn causes the fixed roller 33 on the slip ring 21 to rotate. The fixed roller 33 then drives the sliding roller 35 to rotate via the second track 36. The sliding roller 35 is engaged with the lead screw 34 via the meshing block 41. The lead screw 34 remains stationary, causing the rotating sliding roller 35 to translate along the lead screw 34 until it reaches the end of the lead screw 34. At this point, the slip ring 21, moving with the sliding roller 35, inserts the insert 23 into the groove 25 of the drive roller 24, thus enabling the cutting of the cotton yarn strip. In summary... As described above, for the sliding roller 35 to move to the end of the lead screw 34, the drive shaft 15 needs to rotate a specific number of times. When the distance between the sliding roller 35 and the end of the lead screw 34 is set, the number of rotations of the drive shaft 15 should also be accurately determined. Since the number of rotations of the drive shaft 15 and the take-up roller 5 is the same, the subsequent cutting operation can be automatically performed when the cotton yarn is gathered to a specific length, achieving the purpose of autonomous cutting. There is no need for a series of control elements to operate step by step, which not only reduces the cost input but also simplifies the processing process. The entire cutting process can be completed through a mechanical mechanism, improving the reliability and durability of the device.

[0040] Example 3: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7This invention provides a technical solution: a cotton yarn sliver cutting device for cotton yarn processing, comprising a fixed frame 1, a processing device 2 mounted on the fixed frame 1, and a bracket 3 fixedly connected to the end of the fixed frame 1. A guide roller 4 is rotatably connected to one end of the bracket 3, and a gathering roller 5 is rotatably connected to the other end of the bracket 3. A cutting table 6 is fixedly connected to the top surface of the bracket 3. A sliding groove 7 is provided on the top surface of the cutting table 6. A slide frame 8 is slidably connected in the sliding groove 7. A lifting plate 9 and a pressure strip 10 are slidably connected to the side wall of the slide frame 8. A compression spring 11 is fixedly connected between the lifting plate 9 and the pressure strip 10. A cutter 12 is fixedly connected to the bottom surface of the lifting plate 9. A first connecting block 18, a second connecting block 19 and a fixing fixture 13 are fixedly connected to the bottom surface of the cutting table 6. A motor 14 is mounted on the fixing fixture 13. One end of a transmission shaft 15 is fixedly connected to the output end of the motor 14. A transmission chain 16 is fixedly connected to the other end of the transmission shaft 15. An auxiliary block 17 is sleeved on the transmission shaft 15.

[0041] Please see Figure 1 , Figure 4 and Figure 9 A tension spring is fixed between the side wall of the carriage 8 and the slide 7. The outer surface of the gathering roller 5 is tangent to the top surface of the cutting table 6. The cutter 12 is located above the pressure strip 10. The lifting plate 9 is driven by an electric push rod. The end of the transmission chain 16 is fixed to the end of the gathering roller 5. The auxiliary block 17 is fixed to the bottom surface of the cutting table 6.

[0042] Specifically, during the process of the cutter 12 completely cutting the cotton yarn, the cutter 12 will press down the second piston rod 44 below it, repeating the above principle, so that the slip ring 21 is reset by the return spring 38, and the slide 8 is reset by the return spring, so that the device can cycle through the above process. At the same time, the traction and cutting control of the cotton yarn are both driven by the motor 14. If the traction speed of the cotton yarn is faster, the moving speed of the slide 8 will also increase accordingly, so that the cutter 12, the pressure strip 10 and the cotton yarn can always be kept relatively stationary without the need for additional adjustment devices, further simplifying the operation process.

[0043] The working principle and usage process of this invention are as follows: When it is necessary to cut cotton yarn strips, the cotton yarn strips generated by the processing device 2 are passed through the bottom end of the guide roller 4 and wound onto the take-up roller 5, so that the cotton yarn strips are parallel to the top surface of the cutting table 6. At this time, the second piston rod 44 on the slide 8 is pressed, so that the second piston rod 44 compresses the air in the second sealed chamber 43, thereby increasing the air pressure at the bottom end of the first sealed chamber 39 connected by the air guide pipe 42. This causes the first piston rod 40 in the first sealed chamber 39 to rise, thereby causing the first piston rod 40 to drive the meshing block 41 to rise, thereby disengaging the meshing connection between the meshing block 41 and the lead screw 34. The fixing of the sliding roller 35 and the lead screw 34 is indirectly released. At this time, the sliding roller 35 is moved again so that the distance between the sliding roller 35 and the end of the lead screw 34 reaches the specified length. At the same time, the slip ring 21, which moves with the sliding roller 35, reaches the specified position. Then, the compression of the second piston rod 44 is released, so that the meshing block 41 is reset. Then, the motor 14 on the fixed tooling 13 is started, so that the motor 14 drives the transmission chain 16 to rotate through the transmission shaft 15. This causes the transmission chain 16 to drive the take-up roller 5 to rotate, so that the take-up roller 5 continues to wind the cotton yarn. During the rotation of the transmission shaft 15, the transmission shaft 15 passes through... The guide groove 20 drives the slider 22 to rotate, causing the slip ring 21 on the slider 22 to rotate, which in turn causes the fixed roller 33 on the slip ring 21 to rotate. The fixed roller 33 then drives the sliding roller 35 to rotate via the second track 36. The sliding roller 35 is engaged with the lead screw 34 via the meshing block 41. The lead screw 34 remains stationary, causing the rotating sliding roller 35 to translate along the lead screw 34 until it reaches the end of the lead screw 34. At this point, the slip ring 21, which moves with the sliding roller 35, also inserts the insert 23 into the groove 25 of the drive roller 24, thus enabling the cutting operation of the cotton yarn strip. In summary, for the sliding roller 35 to move to the end of the lead screw 34, the drive shaft 15 needs to rotate a specific number of times. When the distance between the sliding roller 35 and the end of the lead screw 34 is set, the number of rotations of the drive shaft 15 should also be accurately determined. Since the number of rotations of the drive shaft 15 and the take-up roller 5 is the same, the subsequent cutting operation can be automatically performed when the cotton yarn is gathered to a specific length, achieving the purpose of autonomous cutting. There is no need for a series of control elements to operate step by step, which not only reduces the cost input but also simplifies the processing process. The entire cutting process can be completed through a mechanical mechanism, improving the reliability and durability of the device.

[0044] When the aforementioned insert 23 is inserted into the groove 25, the rotation of the slip ring 21 can drive the rotation of the drive roller 24 through the insert 23, causing the first track 26 on the drive roller 24 to drive the driven roller 27 to rotate. This causes the driven roller 27 to drive the drive sprocket 29 to rotate through the shaft 28, causing the chain 30 on the drive sprocket 29 to move. Consequently, the chain 30 drives the carriage 8 to translate along the slide groove 7 through the connecting block 32. Since the transmission chain 16, the drive sprocket 29, and the driven sprocket 31 have the same diameter, the moving speed of the chain 30 is the same as the moving speed of the transmission chain 16. This further makes the translating speed of the carriage 8 the same as the moving speed of the cotton yarn strip. At this point, the electric push is activated. The electric push rod causes the lifting plate 9 to descend, which in turn causes the pressure bar 10 on the lifting plate 9 to descend and squeeze the cotton yarn strip. Because the translation speed of the slide 8 is the same as the movement speed of the cotton yarn strip, the pressure bar 10 and the cotton yarn strip remain relatively stationary, preventing the cotton yarn strip after being squeezed by the pressure bar 10 from being misaligned and piled up. As the lifting plate 9 continues to descend, the compression spring 11 on the pressure bar 10 contracts until the cutter 12 on the lifting plate 9 cuts the cotton yarn strip, achieving the purpose of cutting the cotton yarn strip. There is no need to stop the cotton yarn processing process, which improves the efficiency of cotton yarn processing, avoids losses when the machine is started and stopped, and at the same time ensures the neatness of the cut surface of the cotton yarn strip, improves the cutting effect of the cotton yarn strip, and avoids affecting the quality of the cotton yarn strip.

[0045] When the cutter 12 completely cuts the cotton yarn, it will press down on the second piston rod 44 below it, repeating the above principle. This causes the slip ring 21 to reset under the return spring 38, and the slide 8 to reset under the return spring. This allows the device to cycle through the above process. The traction and cutting control of the cotton yarn are both driven by the motor 14. The faster the traction speed of the cotton yarn, the faster the movement speed of the slide 8 will be. This ensures that the cutter 12, the pressure strip 10, and the cotton yarn remain relatively stationary without the need for additional adjustment devices, further simplifying the operation process.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.
