Description

Technical Field

[0001] This utility model relates to a pressure roller cleaning mechanism for a combed sliver winding machine, belonging to the field of textile machinery technology. Background Technology

[0002] A combed sliver lap machine is a type of machinery used in the textile industry to process combed slivers. Combed slivers are fiber slivers of relatively uniform thickness obtained after being processed by a combing machine during the spinning process. The process of preparing cotton slivers using a combed sliver lap machine involves multiple steps, including the operation of feeding, pressure roller drafting, and winding mechanisms. These mechanisms work together to ensure that the fibers are effectively combed and organized.

[0003] In the drafting process of a combed sliver lap machine, multiple pressure rollers further pressurize the sliver to form a sheet, which is then drafted into the lap-receiving mechanism. Due to impurities (short fibers or dust) from the raw materials themselves, as well as wear or damage during the lap machine's operation, metal debris adheres to the roller surfaces. If these impurities are not cleaned promptly, they can negatively impact the lap-receiving process. For example, impurities may cause uneven sliver compression, affecting the quality of the final product. Furthermore, impurities can accelerate roller wear and shorten their lifespan. Therefore, improvements are necessary. Summary of the Invention

[0004] The purpose of this utility model is to provide a pressure roller cleaning mechanism for a combing sliver winding machine that effectively improves the surface smoothness of the pressure roller, thereby solving the problem of uneven cotton sliver during the pressing process caused by the failure to clean impurities adhering to the surface of the existing pressure roller in a timely manner, which affects the quality of the final product.

[0005] The technical solution of this utility model is: A pressure roller cleaning mechanism for a combed sliver winding machine includes a frame, a first pressure roller, a second pressure roller, a third pressure roller, and a fourth pressure roller. The first pressure roller, the second pressure roller, the third pressure roller, and the fourth pressure roller are movably mounted on the frame at short shaft intervals. The first pressure roller, the second pressure roller, the third pressure roller, and the fourth pressure roller are synchronously driven by a drive assembly. The mechanism is characterized in that: scraper roller assemblies are respectively provided on one side of the frame of the first pressure roller, the second pressure roller, the third pressure roller, and the fourth pressure roller. The scraper roller assembly includes a housing, a scraper, a sliding plate, and a guide plate assembly. The housing is fixedly mounted on the frame, and the sliding plate is movably mounted inside the housing. The sliding plate is detachably connected to the housing by locking bolts. The guide plate assembly is mounted on the sliding plate, and a mounting seat is provided on one side of the sliding plate of the guide plate assembly. The mounting seat has swing arms movably mounted at both ends by torsion springs and pins. The scraper is detachably fixed between the swing arms by bolts. The preload generated by the torsion spring causes the swing arms to push against the scraper, so that the scraper always keeps in contact with the pressure roller.

[0007] The scraper is an elongated body with a triangular cross section, and the end surface of the scraper in contact with the pressure roller is arc-shaped.

[0008] The deflector plate group comprises a support plate, a flat deflector and a folded deflector, one end of the support plate is fixedly connected with the sliding plate, the other end of the support plate is fixedly equipped with the flat deflector, one end of the flat deflector is fixedly equipped with a cover plate, the inner side of the cover plate is fixedly equipped with the folded deflector, the folded deflector is in contact with the box body, and a flow guide channel for guiding the circulation of impurities is formed among the inner wall of the box body, the folded deflector and the flat deflector.

[0009] A flow guide opening is opened on the cover plate between the folded deflector and the flat deflector.

[0015] As attached Figure 1-6 As shown The pressure roller cleaning mechanism of the combed sliver winding machine includes a frame 1, a first pressure roller 2, a second pressure roller 3, a third pressure roller 4, and a fourth pressure roller 5. The first pressure roller 2, second pressure roller 3, third pressure roller 4, and fourth pressure roller 5 are movably mounted on the frame 1 at intervals via short shafts. The first pressure roller 2, second pressure roller 3, third pressure roller 4, and fourth pressure roller 5 are synchronously driven by a drive assembly. The drive assembly includes a drive motor 21, a drive shaft 22, and a mounting plate. The drive motor 21 is fixedly mounted on the frame 1. The drive shaft 22 is movably mounted on the frame 1 corresponding to the drive motor 21. The drive motor 21 is connected to the drive shaft 22. One end of the drive shaft 22 extends to the outside of the frame 1, and a [missing information - likely a component or component] is fixedly mounted on the drive shaft 22 extending to the outside of the frame 1. The driving pulley and the driven pulley are fixed on the short shaft of the first pressure roller 2. The driving pulley and the driven pulley are connected by a transmission belt and a tensioning pulley. The short shafts of the first pressure roller 2, the second pressure roller 3, the third pressure roller 4 and the fourth pressure roller 5 are connected in sequence by gear meshing. During operation, the drive motor 21 drives the driving pulley to rotate counterclockwise. With the cooperation of the transmission belt, the driven pulley rotates counterclockwise synchronously. The driven pulley drives the first pressure roller 2 to rotate counterclockwise. Through the gear meshing action between the first pressure roller 2, the second pressure roller 3, the third pressure roller 4 and the fourth pressure roller 5, the first pressure roller 2 and the third pressure roller 4 rotate counterclockwise synchronously, and the second pressure roller 3 and the fourth pressure roller 5 rotate clockwise synchronously.

[0016] Scraper assemblies are respectively installed on the frame 1 on one side of the first pressure roller 2, the second pressure roller 3, the third pressure roller 4 and the fourth pressure roller 5. The scraper assembly includes a housing 6, a scraper 7, a slide plate 8 and a guide plate assembly. The housing 6 is a long hollow rectangular body with openings at both the top and bottom. The two ends of the housing 6 are fixedly installed on the frame 1.

[0017] A sliding plate 8 is movably mounted on the inner wall of the housing 6, and a limiting strip 9 is provided on the inner side surface of the housing 6. The cross-section of the limiting strip 9 is in a "冂" shape, the inner side of the limiting strip 9 and the sliding plate 8 are slidingly connected through sliding key fit. In use, the limiting strip 9 is used to form a limit for the sliding plate 8.

[0018] The sliding plate 8 is detachably connected to the housing 6 through a locking bolt 10. In use, the locking bolt 10 enables the sliding plate 8 to be fixedly mounted on the inner wall of the housing 6.

[0019] A deflector group is mounted on the sliding plate 8, the deflector group comprises a support plate 11, a flat deflector 12 and a folded deflector 13. One end of the support plate 11 is fixedly connected with the sliding plate 8, the flat deflector 12 is fixedly mounted on the other end of the support plate 11, a cover plate 14 is fixedly mounted at one end of the flat deflector 12, the folded deflector 13 is fixedly mounted on the inner side of the cover plate 14, and the folded deflector 13 is in contact with the box body. A flow guide channel for guiding impurities to circulate is formed among the inner wall of the box body, the folded deflector 13 and the flat deflector 12.

[0020] A flow guide opening 15 is opened on the cover plate 14 between the folded deflector 13 and the flat deflector 12, a connecting pipe can be adhesively connected to the flow guide opening 15, and a suction dust filtering device can be externally connected to the connecting pipe. During operation, the suction dust filtering device can suck and filter impurities in the flow guide channel.

[0021] The flat deflector 12 can be arranged obliquely relative to the inner wall of the housing 6, and can also be arranged parallel to the inner wall of the housing 6. In use, the arrangement can be adjusted according to the position where the doctor roll assembly needs to be arranged among the first press roll 2, the second press roll 3, the third press roll 4 and the fourth press roll 5. When the doctor roll assembly is arranged above the press rolls (the first press roll 2, the second press roll 3, the third press roll 4 and the fourth press roll 5), the flat deflector 12 is arranged obliquely, so that the flow guide channel among the inner wall of the box body, the folded deflector 13 and the flat deflector 12 can better guide impurities to move towards the flow guide opening 15. When the doctor roll assembly is arranged below the press rolls, the flat deflector 12 can be arranged parallel to the inner wall of the housing 6, so that the flow guide channel among the inner wall of the box body, the folded deflector 13 and the flat deflector 12 can better guide impurities to move towards the flow guide opening 15.

[0022] A mounting seat 16 is provided on the sliding plate 8 at one side of the deflector group. Swing arms 18 are movably mounted at both ends of the mounting seat 16 through torsion springs 17 and pivot pins, a scraper 7 is detachably and fixedly mounted between the swing arms 18 through bolts. The scraper 7 is a long strip with a triangular cross-section, and the end surface of the scraper 7 in contact with the press roll is arc-shaped. During operation, the pre-tightening force generated by the torsion springs 17 causes the swing arms 18 to push against the scraper 7, so that the scraper 7 is always kept in contact with the press roll.

[0023] A limiting plate 19 is provided on the mounting base 16. The limiting plate 19 is used to limit the swing arm 18 to prevent the swing arm 18 from swinging too much under the elastic force of the torsion spring 17, which would be inconvenient for subsequent assembly.

[0024] A receiving roller 20 is movably mounted on the frame 1 below the pressure roller via a short shaft. A servo motor 23 is mounted on the frame 1 on one side of the receiving roller 20. The servo motor 23 drives the receiving roller 20 to rotate via a drive pulley and a driven pulley.

[0025] When the pressure roller cleaning mechanism of this combed sliver winding machine is in use, the pre-tension force generated by the torsion spring 17 causes the swing arm 18 to push the scraper 7, so that the scraper 7 always keeps in contact with the pressure roller. When the pressure roller rotates, the scraper 7 scrapes off the impurities on the surface of the pressure roller. The scraped impurities, under their own gravity, move along the guide channel towards the guide port 15. The suction and dust filtration equipment forms a negative pressure suction in the guide channel through the connecting pipe and the guide port 15 to quickly suck up the impurities in the guide channel, thereby ensuring the smoothness of the pressure roller surface and avoiding unevenness of the cotton sliver during the pressing process.

[0026] When the blades of the pressure roller cleaning mechanism of the combing sliver winding machine need to be replaced, the guide plate assembly, slide plate 8, mounting base 16, swing arm 18 and scraper 7 can be removed from the housing 6 by removing the locking bolt 10. Then the scraper 7 can be replaced by loosening the bolts on the swing arm 18.
