Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a cotton sliver traction device for a combed sliver lap machine. Background Technology

[0002] In the cotton textile production process, the combing process plays a key role in improving yarn quality. As the equipment preceding the combing machine, the performance of the sliver lap machine directly affects the combing effect. The main function of the sliver lap machine is to form small laps from several cotton slivers through operations such as drafting, for further processing by the combing machine. In this process, the sliver traction device plays an extremely important role, responsible for drawing the cotton sliver out of the sliver can and conveying it to the subsequent processes in a stable and efficient manner.

[0003] To address the aforementioned problem of sliver traction in combed sliver lap machines, Chinese Patent Publication No. CN222684868U discloses a sliver traction device for a combed sliver lap machine, comprising a fixed base and a sliver can. The fixed base is located above the sliver can, and a first rubber wheel and a second rubber wheel, which can rotate freely, are mounted on the fixed base. The first rubber wheel and the second rubber wheel are at the same height and arranged parallel to each other. A circular guide ring is provided below the first rubber wheel. Both the first rubber wheel and the guide ring are located above the sliver can. A guide rod is provided between the first rubber wheel and the second rubber wheel. This invention adopts passive feeding. During sliver traction, the sliver passes upward through the guide ring, then horizontally through the first rubber wheel, then passes under the guide rod, and then moves backward through the second rubber wheel. The sliver conveying is more stable, suppressing fluctuations during sliver conveying, reducing accidental traction, and reducing sliver breakage.

[0004] The above-mentioned solution proposes a passive feeding method to allow the sliver to pass upward through the guide ring, then horizontally through the first rubber roller, and finally through the underside of the guide rod. This method results in a smoother sliver transport, reduces fluctuations during sliver transport, and minimizes accidental traction. However, in practice, the applicant found that the structural design of the above solution is not conducive to cleaning, which not only affects the quality of the sliver but also leads to the accumulation of impurities and affects the normal operation of the equipment. Therefore, we provide a sliver traction device for combed sliver winding machines. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a cotton sliver traction device for a combed sliver lap machine, including a base plate, side plates fixedly connected to both sides of the base plate, a guide roller provided in front of the side plate, a mounting plate fixedly connected to the top of the opposite side of the side plate, two guide rollers arranged front and back on the opposite side of the mounting plate, a plurality of equally spaced rubber wheels movably sleeved on the outer side of the two guide rollers, and a cleaning mechanism provided below the two guide rollers.

[0006] In some embodiments, the cleaning mechanism includes a U-shaped frame fixedly connected to one side of two mounting plates. A plurality of equally spaced support plates are fixedly connected to the inner side of the U-shaped frame. Limiting telescopic rods are fixedly connected to both sides of the top of each support plate. A force-bearing plate is fixedly connected to the top of the limiting telescopic rod. A cleaning brush is fixedly connected to the top of the force-bearing plate. A buffer spring is fixedly connected to the bottom of the force-bearing plate and located between the two limiting telescopic rods.

[0007] In some embodiments, the position of the cleaning brush corresponds to the position of the rubber wheel sleeved on the outside of the guide roller, and the cleaning brush is in close contact with the bottom of the rubber wheel.

[0008] In some embodiments, the guide roller is fixedly connected to the mounting plate on both sides by connecting rods, and the buffer spring is provided with a damper inside.

[0009] In some embodiments, a plurality of equally spaced guide rings are fixedly sleeved on the outer side of the guide roller, and rotating rods are fixedly connected to both sides of the guide roller, and a clamping structure is provided at the top front end of both side plates.

[0010] In some embodiments, the mounting structure includes a mounting plate fixedly connected to the top of the front end of the side plate, the mounting plate having a mounting groove fixedly opened at the bottom, and a limit screw threadedly connected to the bottom of the front end of the mounting plate.

[0011] In some embodiments, the rotating rod is slidably connected to the mounting groove via a bearing sleeved on the outer side, and the bearing and the mounting groove are fixed together by a limiting screw.

[0012] In some embodiments, the top of the base plate is provided with a plurality of equidistantly distributed tampon tubes, each containing tampons, and the position of the guide ring corresponds to the position of the rubber wheel.

[0013] This utility model has at least the following beneficial effects:

[0014] This invention utilizes a cleaning mechanism. After being guided by a guide ring, the tampons enter a rubber wheel located at the front end. This front rubber wheel changes the direction of the tampons' transport, while a rear rubber wheel ensures stability during transport. During transport, friction causes both front and rear rubber wheels to rotate simultaneously. As the wheels rotate, they contact a cleaning brush, cleaning any impurities adhering to the wheels, preventing accumulation, improving tampon quality, and ensuring normal equipment operation.

Several equidistant support plates 402 are fixedly connected to the inner side of the U-shaped frame 401. Limiting telescopic rods 403 are fixedly connected to both sides of the top of each support plate 402. A force-bearing plate 404 is fixedly connected to the top of the limiting telescopic rods 403. A cleaning brush 405 is fixedly connected to the top of the force-bearing plate 404. A buffer spring 406 is fixedly connected to the bottom of the force-bearing plate 404, located between the two limiting telescopic rods 403. The position of the cleaning brush 405 corresponds to the position of the rubber wheel 106 sleeved on the outer side of the guide roller 105.
