Description

Technical Field

[0001] This utility model relates to an anti-clogging suction cover for a carding machine cover plate, belonging to the field of textile machinery technology. Background Technology

[0002] A carding machine includes a feeding device, a licker-in and cylinder device, a doffer device, and a stripping device. The carding machine uses the movement of needles to comb the lint into single fibers, further removing short fibers and cotton dust impurities, allowing the fibers to re-couple and be layered into wadding of the required size. Above the cylinder of the carding machine are multiple circulating, rolling cover plates. The cover plates' function is to comb larger cotton bundles and thicker cotton layers on the cylinder, resulting in better uniformity. A cleaning brush roller is located at one end of the cover plate. The cleaning brush roller's function is to remove short fibers and cotton dust impurities adhering to the carding cloth on the cover plate. A suction hood is located below the cleaning brush roller. (See appendix) Figure 5 The suction cover surrounds the end of the cover plate, and a suction port is provided on the inner side of the suction cover. Short lint and cotton dust impurities slide along the suction cover to the suction port, where they are sucked up. Due to the long-term friction between the short lint and cotton dust impurities and the inner side of the suction cover, cotton dust is easily attracted by static electricity on the inner side of the suction cover. If the inner side of the suction cover is not cleaned for a long time, cotton dust impurities can easily accumulate on the inner side of the suction cover, clogging other short lint and cotton dust impurities. This causes the short lint and cotton dust impurities to re-adhere to the cover plate needle cloth, affecting the cleanliness of the cover plate. On the other hand, manual disassembly of the suction cover is time-consuming, labor-intensive, and cumbersome, and the manual cleaning workload is large. Therefore, it is necessary to improve it. Summary of the Invention

[0003] The purpose of this invention is to provide an anti-clogging suction cover for carding machine covers that reduces the amount of manual disassembly and cleaning work, and solves the problem of cotton dust and impurities accumulating on the inner wall of the suction cover, causing blockages to other short fibers and cotton dust impurities and affecting the cleanliness of the cover.

[0004] The technical solution of this utility model is: A clogging-proof suction cover for a carding machine cover includes a cover body, a scraper, and a reciprocating assembly. The cover body contains a scraper with a connecting rod. A clearance groove is provided within the cover body corresponding to the connecting rod. One end of the connecting rod passes through the clearance groove. A reciprocating assembly is mounted on the back of the cover body on one side of the connecting rod. The reciprocating assembly is detachably and fixedly connected to the connecting rod. The reciprocating assembly controls the scraper to reciprocate along the inner side of the cover body via the connecting rod, thereby loosening the cotton dust inside the cover body and reducing the accumulation of cotton dust within the cover body.

[0005] The cover is arc-shaped, with baffles fixed at both ends and a dust suction pipe at the bottom. The dust suction pipe and the inner side of the cover have suction ports.

[0006] The aforementioned clearance groove is elongated, and an aluminum curtain protective cover is installed between the connecting rod and the clearance groove. The aluminum curtain protective cover is flush with the inner side of the cover.

[0007] The reciprocating assembly includes a drive motor, a reciprocating lead screw, and a sliding shuttle. The reciprocating lead screw is movably mounted on the cover. A guide rod is fixedly mounted on one side of the cover. A slider is movably mounted on the reciprocating lead screw, and a sliding shuttle is movably mounted inside the slider. The surface of the reciprocating lead screw has two threaded grooves with the same pitch but opposite directions, connected at both ends by a transition curve. The sliding shuttle is embedded in the helical groove of the reciprocating lead screw. The slider and the guide rod are slidably connected. A drive motor is fixedly mounted on the cover corresponding to the reciprocating lead screw via a motor mounting bracket, and the drive motor is connected to the reciprocating lead screw.

[0008] The scraper includes a frame and bristles. The frame is arc-shaped, and bristles are provided on the outer edge of the frame, with the bristles contacting the inner side of the cover.

[0009] The scraper includes a frame and a rubber plate. The frame is arc-shaped, and a rubber plate is provided on the outer edge of the frame. The rubber plate is in contact with the inner side of the cover.

[0010] The advantages of this utility model compared with the prior art are as follows: This anti-clogging suction cover for carding machine covers uses a drive motor to rotate a reciprocating screw shaft in one direction. The reciprocating screw shaft has two threaded grooves with the same pitch but opposite directions, connected at both ends by a transition curve. A sliding shuttle is embedded in the spiral groove, cooperating with the reciprocating screw shaft. When the slider and shuttle reach the end of the spiral groove, the transition curve guides them to move in opposite directions, thus achieving the reciprocating motion of the slider. During this reciprocating motion, the slider drives a scraper to reciprocate synchronously. The scraper cleans the cotton dust adsorbed on the inner side of the cover, effectively reducing the labor required for manual disassembly and cleaning. This solves the problem of existing cotton dust and impurities accumulating on the inner wall of the suction cover, clogging other short fibers and cotton dust, causing these impurities to return to the cover and affecting its cleanliness.

[0013] As attached Figure 1-6 As shown The anti-clogging suction cover for the carding machine cover includes a cover body 1, a scraper and a reciprocating assembly. The cover body 1 is arc-shaped, with baffles 2 fixedly installed at both ends. A suction pipe 3 is provided at the bottom of the cover body 1, and suction ports 4 are provided on the inner side of the cover body 1 through the suction pipe 3. In use, the two ends of the suction pipe 3 are connected to the dust filter negative pressure through corrugated pipes. The suction ports 4 can generate negative pressure, which can suck up short fibers and cotton dust impurities inside the cover body 1.

[0014] A scraper is installed inside the cover 1. The scraper includes a frame 5 and bristles 6. The frame 5 is arc-shaped, and bristles 6 are provided on the outer edge of the frame 5. The bristles 6 contact the inner side of the cover 1. When working, the frame 5 of the scraper is set in the same shape as the inner side of the cover 1, and the bristles 6 of the scraper can clean the cotton dust adsorbed on the inner side of the cover 1.

[0015] The scraper is equipped with a connecting rod 13, and a clearance groove 7 is provided in the cover 1 corresponding to the connecting rod 13. The clearance groove 7 is long and narrow, and one end of the connecting rod 13 passes through the clearance groove 7.

[0016] A reciprocating assembly is mounted on the back of the cover 1 on one side of the connecting rod 13. The reciprocating assembly includes a drive motor 8, a reciprocating lead screw shaft 10, and a sliding shuttle 11. The reciprocating lead screw shaft 10 is movably mounted on the cover 1. A guide rod 12 is fixedly mounted on the cover 1 on one side of the reciprocating lead screw shaft 10. A slider 9 is movably mounted on the reciprocating lead screw shaft 10. A sliding shuttle 11 is movably mounted inside the slider 9. One end of the sliding shuttle 11 is crescent-shaped, and the other end is cylindrical. The surface of the reciprocating lead screw shaft 10 is machined with two threaded grooves of the same pitch but opposite directions. The two ends are connected by a transition curve. The sliding shuttle 11 is embedded in the helical groove of the reciprocating lead screw shaft 10. One end of the cylindrical sliding shuttle 11 is movably connected to the slider 9, and the other end of the crescent-shaped sliding shuttle 11 is embedded in the reciprocating lead screw shaft 10. The slider 9 and guide rod 12 are slidably connected within the spiral groove of the screw shaft 0. The guide rod 12 provides limiting and guiding functions for the slider 9. The drive motor 8 is fixedly installed on the cover 1 corresponding to the reciprocating screw shaft 10 through the motor mounting seat. The drive motor 8 is connected to the reciprocating screw shaft 10. During operation, the drive motor 8 drives the reciprocating screw shaft 10 to rotate in one direction. Since the surface of the reciprocating screw shaft 10 has two threaded grooves with the same pitch but opposite directions, the two ends are connected by a transition curve. The shuttle 11 is embedded in the spiral groove and forms a cooperation with the reciprocating screw shaft 10. When the slider 9 and the shuttle 11 reach the end of the spiral groove, the transition curve guides the slider 9 and the shuttle 11 to move in opposite directions, thereby realizing the reciprocating motion of the slider 9.

[0017] The slider 9 of the reciprocating assembly is detachably and fixedly connected to the connecting rod 13. The purpose of this design is to facilitate the replacement of the connecting rod 13 and the scraper after they are worn.

[0018] The reciprocating assembly controls the scraper to reciprocate along the inside of the cover 1 via the connecting rod 13 to loosen the cotton dust inside the cover 1 and reduce the amount of cotton dust accumulating inside the cover 1.

[0019] An aluminum curtain protective cover (not shown in the figure) is provided between the connecting rod 13 and the relief slide 7. The aluminum curtain protective cover is a commercially available part. The aluminum curtain protective cover is flush with the inner side of the cover body 1. When in use, the aluminum curtain protective cover protects the relief slide 7 and prevents cotton dust from running out of the relief slide 7. The aluminum curtain protective cover does not affect the reciprocating sliding of the connecting rod 13 in the relief slide 7.

[0020] When the anti-clogging suction cover for the carding machine cover is in operation, the drive motor 8 is started first. The drive motor 8 drives the reciprocating screw shaft 10 to rotate in one direction. Since the surface of the reciprocating screw shaft 10 is machined with two threaded grooves with the same pitch but opposite directions, the two ends are connected by a transition curve. The sliding shuttle 11 is embedded in the spiral groove and cooperates with the reciprocating screw shaft 10. When the slider 9 and the sliding shuttle 11 reach the end of the spiral groove, the transition curve guides the slider 9 and the sliding shuttle 11 to move in opposite directions, thereby realizing the reciprocating motion of the slider 9. When the slider 9 reciprocates, the slider 9 drives the scraper to reciprocate synchronously. The scraper can clean the cotton dust adsorbed on the inner side of the cover 1. Compared with the existing suction cover 15, the anti-clogging suction cover for the carding machine cover effectively reduces the amount of labor required to manually disassemble and clean the cover 1. It solves the problem that cotton dust and impurities accumulate on the inner wall of the existing suction cover 15, causing blockage of other short fibers and cotton dust impurities, which leads to other short fibers and cotton dust impurities returning to the cover and affecting the cleanliness of the cover.

[0021] As an improvement of this utility model, the scraper includes a frame 5 and a rubber plate 14. The frame 5 is arc-shaped, and the rubber plate 14 is provided on the outer edge of the frame 5. The rubber plate 14 contacts the inner side of the cover 1. When working, the frame 5 of the scraper is set in the same shape as the inner side of the cover 1, and the rubber plate 14 of the scraper can clean the cotton dust adsorbed on the inner side of the cover 1.
