Description

Technical Field

[0001] The invention relates to the technical field of carding machine equipment, and in particular to an automatic cotton web cleaning device for a carding machine and a cleaning method thereof. Background Art

[0002] Carding machine is used to process cotton fiber and chemical fiber. It belongs to textile machinery. According to the spinning process, carding is one of the important steps. The carding machine will open, comb and remove impurities from the delivered cotton rolls or the oily cotton layer supplied by the cotton box, so that all the curled cotton loops become basically straight single fibers.

[0003] Existing carding machines have some drawbacks. For example, during the carding process, when the licker-in roller combs the cotton through the teeth on the surface of the roller body, a large amount of cotton wool will remain between adjacent comb teeth. If there are too many residual impurities, the efficiency of carding will be affected, and the overall quality of the cotton fibers processed subsequently will also be affected.

In the initial state, the piston plate 222 blocks all the jet holes 24. After the piston plate 222 slides and squeezes the arc groove 23, the gas will pass through the air cavity 25 and the air outlet holes 26. After the air outlet holes 26 are aligned with a row of jet holes 24, the gas will be ejected from the row of jet holes 24 aligned with the air outlet holes 26. The jet holes 24 that eject gas are just aligned with the connecting groove 20 of the scraper 502, thereby blowing cotton wool impurities into the annular cavity 18, wherein the elastic push rod 27 and the air outlet groove are located on the same row to ensure that the ejected gas can face the connecting groove 20.

When the driving roller 12 rotates, the intermittent push rod 60 will intermittently match with the matching rod 61, so that the annular piston plate 561 moves back and forth continuously, so that the air guide hole 55 continuously ejects gas, so that the cotton wool entering the annular cavity 18 is continuously guided to the air duct 21 through the annular cone 54 (see Figure 1 ) at one end to prevent the axial distance of the annular cavity 18 from being too long and affecting the cotton wool cleaning effect. The one-way valve 57 can prevent the cotton wool in the annular cavity 18 from being sucked into the air guide hole 55.

[0028] See also Figure 1-14As shown, when the device is in use, the motor 9 drives the driving roller 12 to rotate, and the driving roller 12 rotates and drives the licker-in roller 2 and the driving roller 12 to reverse through the cooperation of the toothed disk 13, the second gear 15 and the second annular tooth portion 14. During the rotation of the licker-in roller 2, the cotton web is combed. During the combing of the cotton web, cotton wool will adhere to between adjacent annular comb teeth 202. During the reverse rotation of the driving roller 12 and the licker-in roller 2, the toothed ring 8 will mesh with the first gear 7 and drive the first gear 7 to rotate. The rotation of the first gear 7 will mesh with the first annular tooth portion 64 to rotate the first gear 7. The annular sleeve 501 is driven to rotate on the licker-in roller 2, and the rotation of the annular sleeve 501 will drive the scraper bar 502 to rotate. After the cotton wool enters the cleaning area 4, the scraper bar 502 will take the cotton wool away. When the scraper bar 502 passes the position of the arc plate 221, the scraper bar 502 will abut against the inclined surface 31 of the second push rod 272. Under the action of the second spring 30, at the beginning, the second push rod 272 and the first push rod 271 jointly drive the piston plate 222 to slide in the arc groove 23 and compress the space in the arc groove 23. When the piston plate 222 moves, the gas will pass through the outlet. The row of jet holes 24 aligned with the hole 26 sprays toward the connecting groove 20, and sprays the cotton wool at the position of the connecting groove 20 into the annular cavity 18. At the same time, under the action of the third spring 43, the third gear 40 will bounce into the first side groove 37 and mesh with the arc-shaped tooth portion 39, thereby driving the driving rod 331 to rotate. The rotation of the driving rod 331 will drive the cotton scraping plate 332 to move through the cooperation of the reciprocating spiral groove 35 and the guide block 36, so that the cotton wool can be better concentrated and then blown into the annular cavity 18. In the process of the annular sleeve 501 rotating and driving the scraper bar 502 to rotate in the cleaning area 4, the scraper bar 5 02 passes through the second side groove 52, under the action of the first return spring 50, one end of the long drive rod 472 will be inserted into the second side groove 52, so that the shift block 48 is abutted against the cotton inserting rod 471 and pushes one end of the cotton inserting rod 471 to slide out to the outside of the scraper bar 502, and the cotton inserting rod 471 can destroy the rolled cotton wool and assist the scraper bar 502 to remove the cotton wool. After the long drive rod 472 passes through the second guide bevel 53 and leaves the two side grooves, the long drive rod 472 will be pushed into the drive rod groove 28 again. At this time, the cotton inserting rod 471 will slide into the cotton rod groove 28, completing the cotton wool destruction effect.

[0029] In addition, during the rotation of the annular sleeve 501, the baffle 46 will continue to scrape the cotton wool on the annular sleeve 501 to the position of the scraper bar 502. When the scraper bar 502 abuts against the baffle 46, it will drive the baffle 46 to rotate. After the scraper bar 502 passes, the baffle 46 will return to its initial position under the action of the torsion spring.

[0030] After the cotton wool enters the annular cavity 18 through the connecting groove 20 at the position of the scraper strip 502, the cotton wool impurities entering the annular cavity 18 can be extracted through the air duct 21 by an external induced draft fan. At the same time, during the rotation of the driving roller 12, the intermittent abutment rod 60 intermittently abuts against the matching rod 61, and the annular piston plate 561 is cyclically driven to slide in the piston cavity through the annular push plate 563, so that the air guide holes 55 on the cone body continuously spray gas, which helps to blow the cotton wool impurities in the annular cavity 18 away from the side of the air duct 21 to the side of the air duct 21.
