Description

Technical Field

[0001] The utility model belongs to the technical field of yarn processing, and in particular relates to a polyester yarn spinning feeding device. Background Art

[0002] During the polyester spinning process, slivers are first drawn out and thinned into rovings on a roving frame, forming the initial yarn form. The rovings are then further refined on a spinning frame to increase the yarn's strength and uniformity, ultimately resulting in a qualified yarn product. During the yarn feeding and drawing process, impurities such as fibers and lint may adhere to the rollers. If not cleaned promptly, these impurities can affect yarn quality.

[0003] Chinese patent document: 201821950097.2 discloses a roving machine, which includes a material guide device, a feeding device, a twisting mechanism, and a winding mechanism. In the feeding device, one end of a scraper is in close contact with a soft pressure roller. The rotation of the soft pressure roller allows the scraper to remove dust and fiber impurities on the roller. The air jet head then sprays air on the scraped side to perform a secondary cleaning of the cotton wool that was not scraped clean. In the actual feeding process of the cotton strips, longer fibers will be wrapped around the pressure roller. Even if a scraper is used to remove the long fiber impurities on the pressure roller, due to the close contact between the scraper and the pressure roller, some fibers will accumulate on the scraper. If the scraper is not cleaned in time, the cleaning effect of the scraper will eventually decrease. Utility Model Content

[0004] In view of the above problems, the utility model discloses a polyester yarn spinning feeding device, which solves the problem that the feeding device in the prior art cannot effectively remove fiber impurities attached to the roller shaft.

[0005] The specific technical solutions are as follows:

[0006] A polyester yarn spinning feeding device comprises a frame, a feeding roller is rotatably provided on the frame, a pressure roller is provided at one end of the feeding roller, and a scraping cleaning device is provided on the frame at the other end of the feeding roller, the scraping cleaning device comprises a debris suction pipe, a debris collection box, a debris scraping plate, a rotary drive device, a mounting support and a debris removing plate, the mounting support is horizontally arranged in the frame, one end of the debris removing plate is hingedly provided on the mounting support, one end of the debris removing plate is pressed downward on the mounting support under the support of an elastic member, and the other end of the debris removing plate is arranged toward the direction of the feeding roller; both ends of the debris suction pipe are rotatably provided on the frame The scraping plate is installed on the upper surface of the suction nozzle, and the scraping plate is inclined, and the upper end of the scraping plate is in contact with the surface of the feeding roller. The scraping plate is driven to rotate by the rotary driving device arranged on the frame; the scraping plate is rotated upward and abuts against one end of the scraping plate by the rotary driving device.

[0007] Furthermore, a push plate is obliquely provided on one side of the suction pipe, and the push plate is connected to a rotation drive device provided on the frame, so that the rotation drive device drives the suction pipe to rotate back and forth.

[0008] Furthermore, the rotation drive device is an electric push rod.

[0009] Furthermore, one end of the shredder plate is horizontally arranged, and the other end is inclined upwardly arranged. The two sides of the horizontal end of the shredder plate are respectively hingedly connected to the two sides of the mounting support through a hinge shaft. The hinge shaft is sleeved with the elastic member, which is a torsion spring. One end of the torsion spring presses against the mounting support, and the other end of the torsion spring presses against the upper end of the shredder plate, thereby realizing the pressing and positioning of the shredder plate by the elastic member.

[0010] Furthermore, the debris removal plate is an elastic metal sheet.

[0011] Furthermore, the width of the scraping plate and the sifting plate is adapted to the length of the feeding roller.

[0012] The beneficial effects of the present invention are as follows:

[0013] (1) The present invention adopts a scraping and cleaning device to scrape and clean the impurities such as fiber fluff on the surface of the feed roller. The impurities are first scraped by a scraping plate fixed on the suction nozzle, and then the impurities scraped off are adsorbed and cleaned by the suction pipe at the lower end, thereby ensuring the cleanliness of the feed roller surface.

[0014] (2) When some impurities such as fiber shorts adhere to the scraping plate, the electric push rod can be started regularly to make the suction pipe rotate back and forth and drive the scraping plate and the debris removal plate to abut and cooperate multiple times, so as to achieve the effect of completely removing the impurities on the scraping plate. No manual cleaning is required, which ensures the continuous and stable operation of the scraping and cleaning device. BRIEF DESCRIPTION OF THE DRAWINGS
