Description

Technical Field

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

[0002] A carding machine is used for processing cotton fibers and chemical fibers and belongs to textile machinery. According to the spinning process flow, carding is an important process. The carding machine opens, combs, and removes impurities from the incoming cotton lap or the oiled cotton layer supplied by the cotton box, so that all the curly and lumpy cotton loops become single fibers that are basically straightened.

[0003] Existing carding machines have some drawbacks. For example, when the carding roller combs cotton during the carding process, a large amount of cotton fluffs will remain between adjacent comb teeth. When too much residual impurities accumulate, it will affect the carding efficiency and at the same time the overall quality of the cotton fibers for subsequent processing. To ensure the carding effect, people often manually clean it after stopping the machine, but the effect of removing impurities is poor and it affects the carding efficiency. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0038] Please refer toFigure 1-12 The present invention provides a first embodiment:

[0039] Referring to Figure 1 and 6 -9, an automatic cotton web cleaning device for a carding machine, comprising a carding machine case 1. A licker-in 2 is rotatably provided in the carding machine case 1. The licker-in 2 includes a roller body 201 and a plurality of groups of annular comb teeth 202 arranged axially. A comb tooth area 3 and a cleaning area 4 are formed between adjacent annular comb teeth 202. The cleaning area 4 is an annular area close to the roller body 201, and the comb tooth area 3 is an annular area adjacent to the cleaning area 4. During the process of carding cotton by the rotation of the annular comb teeth 202, some cotton fluffs and impurities will preferentially adhere to the comb tooth area 3. If not cleaned in time, the cotton fluffs in the comb tooth area 3 will thicken and be squeezed into the cleaning area 4, resulting in a poor carding effect of the licker-in 2 on the cotton web and at the same time, the cotton fluffs on the licker-in 2 are easily taken away by the cotton web, affecting the quality of the cotton web finished product. A cleaning mechanism 5 for cleaning the cleaning area 4 is provided on the licker-in 2. The cleaning mechanism 5 can prevent the continuous increase of cotton fluffs between adjacent annular comb teeth 202 and ensure the carding effect of the annular comb teeth 202 on the cotton web;

[0040] The cleaning mechanism 5 includes an annular sleeve 501 and a scraping strip 502. An annular rotating groove 6 is provided on the side wall of the annular comb teeth 202. The two axial ends of the annular sleeve 501 are respectively inserted into the annular rotating grooves 6 on both sides. There are multiple groups of annular sleeves 501, and they are respectively rotatably arranged between adjacent annular comb teeth 202 through cooperation with the annular rotating grooves 6. It also includes a driving mechanism for driving the annular sleeve 501 to rotate on the carding roller 2. The driving mechanism includes a first gear 7, a toothed ring 8, and a motor 9. A through groove 10 is provided in the roller body 201 at each cleaning area 4. There are multiple groups of the first gears 7, and they are respectively rotatably arranged in each through groove 10. A connecting shaft 11 is also rotatably provided in the roller body 201. The connecting shaft 11 passes through the center position of each group of first gears 7 and forms a fixed connection. A driving roller 12 is coaxially provided in the hollow interior of the carding roller 2. One axial end of the driving roller 12 is fixedly connected to the output end of the motor 9 and is rotatably arranged in the carding machine box 1 through the drive of the motor 9. A toothed disc 13 is provided at one end of the driving roller 12. A second annular tooth portion 14 is provided on the annular inner wall at one end of the roller body 201. A second gear 15 is meshed between the toothed disc 13 and the second annular tooth portion 14. One axial end of the second gear 15 is provided with a rotating rod 16. The second gear 15 is rotatably arranged in the carding machine box 1 through the rotating rod 16. Among them, an extension ring is provided on the inner wall of the carding machine box 1. The two axial ends of the carding roller 2 are rotatably connected through cooperation with the extension ring by bearings. A fixing rod 17 is fixed between the driving roller 12 and the toothed ring 8. An annular cavity 18 is formed between the carding roller 2 and the driving roller 12. An arc-shaped groove body 19 communicating with the annular cavity 18 is provided on the roller body 201. A communication groove 20 is provided between the scraping strip 502 and the annular sleeve 501. After the scraping strip 502 scrapes off the cotton floc impurities, they can enter the annular cavity 18 through the communication groove 20. It should be noted that: A wind pipe 21 is provided at one end of the carding machine box 1 away from the motor 9 in the annular cavity 18. An induced draft fan can be connected to the outside of the wind pipe 21. The cotton floc impurities entering the annular cavity 18 can be sucked away and collected by the induced draft fan. (For the connection method between the wind pipe 21 and the annular cavity 18, refer to Figure 15 , in order to ensure that both axial ends of the driving roller 12 are rotatably connected to the box wall of the carding machine box 1, a long rod 63 is connected between the inner wall of the wind pipe 21 on the carding machine box 1 and the box wall of the carding machine box 1); In addition, it should be noted that: The scraping strip 502 does not extend beyond the cleaning area 4 to avoid affecting the carding effect of the annular comb teeth 202.

[0041] Refer to Figure 1-5, in order to enable the cotton floss and impurities scraped by the scraping strip 502 to smoothly enter the annular cavity 18, an air jet mechanism 22 for driving the cotton floss and impurities on the scraping strip 502 to enter the annular cavity 18 through the communication groove 20 and the arc-shaped groove body 19 is provided on the sawtooth cylinder 2. The air jet mechanism 22 includes an arc-shaped plate 221 arranged between adjacent annular comb teeth 202, and also includes a piston plate 222. An arc-shaped groove 23 for the piston plate 222 to slide is provided in the arc-shaped plate 221. A plurality of groups of air jet holes 24 are provided at one end of the inner arc of the arc-shaped plate 221. An air cavity 25 is provided in the piston plate 222, and an air outlet hole 26 is provided on the inner arc of the piston plate 222. An elastic abutting rod 27 for abutting against the scraping strip 502 is further provided on the inner arc of the piston plate 222. An elastic abutting rod groove 62 for the elastic abutting rod 27 to slide is provided at the bottom of the arc-shaped plate 221. Each time the scraping strip 502 abuts against the elastic abutting rod 27, the piston plate 222 is driven to slide cyclically once, so that a gas is ejected from the air cavity 25. Among them, there are multiple rows of air jet holes 24, and the air outlet hole 26 is one row. In the initial state, the piston plate 222 blocks all the air jet holes 24. After the piston plate 222 slides and compresses the arc-shaped groove 23, the gas will pass through the air cavity 25 and the air outlet hole 26. After the air outlet hole 26 aligns with one row of air jet holes 24, the gas will be ejected from the row of air jet holes 24 aligned with the air outlet hole 26. The air jet holes 24 from which the gas is ejected are exactly aligned with the communication groove 20 of the scraping strip 502, so as to blow the cotton floss and impurities into the annular cavity 18. Among them, the elastic abutting rod 27 and the air outlet groove are on the same row, ensuring that the ejected gas can be directly opposite to the communication groove 20.

[0042] In order to enable the piston plate 222 to reset after the scraping strip 502 abuts against the elastic abutting rod 27, the elastic abutting rod 27 includes a first abutting rod 271 and a second abutting rod 272. A rod groove 28 is provided at the bottom of the first abutting rod 271. A sliding rod 29 which forms a sliding connection with the rod groove 28 is provided at the top of the second abutting rod 272. The sliding rod 29 is non-cylindrical. A second spring 30 connected to the sliding rod 29 is provided in the rod groove 28. An inclined surface 31 for abutting against the scraping strip 502 is provided at the bottom of the second abutting rod 272. The scraping strip 502 abuts against the inclined surface 31 and drives the piston plate 222 to slide in the arc-shaped groove 23 through the elastic abutting rod 27. After the piston plate 222 cannot slide, the second abutting rod 272 is driven to slide towards the first abutting rod 271 side by the abutting of the scraping strip 502 against the inclined surface 31, ensuring that the scraping strip 502 can pass through the second abutting rod 272. A first spring 32 for driving the piston plate 222 to slide and then reset is provided at one end of the arc-shaped groove 23. After the scraping strip 502 passes the second abutting rod 272, the first spring 32 will reset the piston plate 222.

[0043] In order to further enable the cotton fluffs and impurities on the scraping strip 502 to better enter the annular cavity 18, a cotton scraping assembly 33 is provided at the position of the communication groove 20 on the scraping strip 502. The cotton scraping assembly 33 includes a driving rod 331 and a cotton scraping plate 332. A fixing plate 34 is provided in the middle of the communication groove 20. The driving rod 331 is rotatably arranged on the fixing plate 34. Reciprocating spiral grooves 35 are provided on both sides of the fixing plate 34 for the driving rod 331. The cotton scraping plates 332 are respectively arranged on both sides of the fixing plate 34 and are sleeved on the driving rod 331. Guide blocks 36 which form a sliding fit with the reciprocating spiral grooves 35 are provided on the cotton scraping plates 332. A linkage structure for driving the driving rod 331 to rotate is provided on the spiked roller 2. A first side groove 37 is provided on the inner wall of the arc-shaped plate 221 in the cleaning area 4 of the annular comb teeth 202. First guide inclined surfaces 38 are provided at both arc-shaped ends of the first side groove 37. The linkage structure includes an arc-shaped tooth part 39 arranged in the first side groove 37. The linkage structure further includes a third gear 40 for meshing with the arc-shaped tooth part 39. Sliding grooves 41 are provided at both axial ends of the driving rod 331. A short rod 42 which forms a sliding fit with the sliding grooves 41 is axially provided on the third gear 40. A third spring 43 connected to the short rod 42 is provided in the sliding grooves 41. Each time the scraping strip 502 passes through the position of the arc-shaped plate 221, the third spring 43 will drive the third gear 40 to move outwards into the first side groove 37, so that the third gear 40 meshes with the arc-shaped tooth part 39. The third gear 40 meshes and rotates with the arc-shaped tooth part 39 and drives the cotton scraping plates 332 on both sides to move. The end faces on both sides of the cotton scraping plate 332 are inclined, which is convenient for scraping off the cotton fluffs and cooperating with the air jet mechanism 22 to enable the cotton fluffs and impurities to enter the annular cavity 18. After the third gear 40 meshes with the arc-shaped tooth part 39, it passes through the first guide inclined surface 38 to make the third gear 40 leave the first side groove 37.

[0044] Refer to Figure 3 , in order to reduce the friction between the third gear 40 and the annular comb teeth 202, a conical inclined surface 44 is provided at one end of the third gear 40, and guide rollers 45 are rotatably arranged at both axial ends of the third gear 40.

[0045] Refer to Figure 6 , 7 , one end of the arc-shaped plate 221 is hinged with a baffle 46. The baffle 46 is rotatably arranged between adjacent annular comb teeth 202 through a rotating shaft. A torsion spring is connected between the rotating shaft and the annular comb teeth 202. During the rotation of the annular sleeve 501, the bottom end of the baffle 46 continuously contacts the surface of the annular sleeve 501 and scrapes the cotton fluffs and impurities to the position of the scraping strip 502, which is convenient for cleaning the cotton fluffs and impurities on the annular sleeve 501.

[0046] Refer to Figure 6 , 7, 11. To prevent cotton wool from forming loops outside the annular sleeve 501, making it difficult for the scraping strip 502 to scrape off the cotton wool, a cotton cleaning auxiliary component 47 is provided inside the scraping strip 502. The cotton cleaning auxiliary component 47 includes a cotton inserting rod 471 and a long driving rod 472. The cotton inserting rod 471 is provided with multiple groups along the length direction of the scraping strip 502 and is slidably arranged on the scraping strip 502 along the radial direction of the spiked roller 2. Among them, a cotton rod groove 28 for the cotton inserting rod 471 to slide is provided inside the scraping strip 502, and a driving rod groove 28 for the long driving rod 472 to slide is provided inside the scraping strip 502. There are two groups of long driving rods 472 symmetrically slidably arranged in the driving rod groove 28. The sliding direction of the long driving rod 472 is perpendicular to the sliding direction of the cotton inserting rod 471. At each position of the cotton inserting rod 471, the long driving rod 472 is provided with a dial block 48, and each dial block 48 is provided with a second inclined surface 49. The bottom end of the cotton inserting rod 471 is provided with a third inclined surface that abuts against the second inclined surface 49. A first return spring 50 is provided inside the scraping strip 502 to drive the long driving rod 472 to slide outwards and make the second inclined surface 49 abut against the third inclined surface. When the annular sleeve 501 rotates and the scraping strip 502 is located at the second side groove 52 position, the first return spring 50 will drive the long driving rod 472 to slide outwards until one end is located inside the second side groove 52. By the abutment of the second inclined surface 49 and the third inclined surface, the cotton inserting rod 471 is driven to slide outwards, so that the cotton inserting rod 471 inserts into the cotton wool and rotates with the annular sleeve 501 for a period of time, preventing the cotton wool from forming a ring structure, which is beneficial for the scraping strip 502 to scrape away the cotton wool. A scraping groove is provided in the cotton rod groove 28, a limiting plate that forms a sliding connection with the scraping groove is provided on the outer wall of the cotton inserting rod 471, and a second return spring 51 that abuts against the limiting plate is provided in the scraping groove. On the side wall of the annular comb teeth 202, a second side groove 52 for one end of the long driving rod 472 to slide into is provided. The arc-shaped two ends of the second side groove 52 are provided with second guiding inclined surfaces 53, and the second guiding inclined surfaces 53 facilitate the sliding of the long driving rod 472 and its reset to the driving rod groove 28.

One end of the annular piston plate 561 is connected with a plurality of connecting rods 562. The end of the connecting rod 562 far from the annular piston plate 561 penetrates out of the outer end of the annular cone 54 and is connected with an annular push plate 563. The annular push plate 563 is fixed on the driving roller 12. A third return spring 59 is provided between the annular push plate 563 and the annular cone 54. A plurality of intermittent abutting rods 60 are provided along the circumferential side of the end of the annular push plate 563 far from the connecting rod 562. One end of the second gear 15 far from the rotating rod 16 is provided with a mating rod 61 for cooperating with the intermittent abutting rod 60. A fifth inclined surface (not shown in the figure) for abutting against the mating rod 61 is provided on each intermittent abutting rod 60. When the driving roller 12 rotates, the intermittent abutting rod 60 will intermittently abut against the mating rod 61, causing the annular piston plate 561 to continuously reciprocate, causing the air guide hole 55 to continuously spray gas, and causing the cotton wool entering the annular cavity 18 to be continuously guided to one end of the air duct 21 (see Figure 1 ), avoiding the axial distance of the annular cavity 18 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.

[0049] Please refer to Figure 1-14As shown, when the device is in use, the motor 9 drives the driving roller 12 to rotate. The driving roller 12 rotates and drives the licker-in roller 2 to rotate in the reverse direction through the cooperation of the toothed disc 13, the second gear 15 and the second annular tooth part 14. During the rotation of the licker-in roller 2, the cotton web is carded. During the carding of the cotton web, the cotton fluffs will adhere between the 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 engage with the first gear 7 and drive the first gear 7 to rotate. The rotation of the first gear 7 will drive the annular sleeve 501 to rotate on the licker-in roller 2 through the engagement with the first annular tooth part 64. The rotation of the annular sleeve 501 will drive the scraping strip 502 to rotate. After the cotton fluffs enter the cleaning area 4, the scraping strip 502 will take away the cotton fluffs. When the scraping strip 502 passes through the position of the arc-shaped plate 221, the scraping strip 502 will abut against the inclined surface 31 of the second abutting rod 272. Under the action of the second spring 30, initially, the second abutting rod 272 and the first abutting rod 271 jointly drive the piston plate 222 to slide in the arc-shaped groove 23 and compress the space in the arc-shaped groove 23. When the piston plate 222 moves, the gas will be sprayed into the communication groove 20 through a row of air spray holes 24 aligned with the air outlet holes 26 and spray the cotton fluffs at the position of the communication groove 20 into the annular cavity 18. At the same time, under the action of the third spring 43, the third gear 40 will pop into the first side groove 37 and engage with the arc-shaped tooth part 39, thereby driving the driving rod 331 to rotate. The rotation of the driving rod 331 will drive the scraping plate 332 to move through the cooperation of the reciprocating spiral groove 35 and the guide block 36, so that the cotton fluffs can be better concentrated and blown into the annular cavity 18; during the rotation of the annular sleeve 501 driving the scraping strip 502 to rotate in the cleaning area 4, when the scraping strip 502 passes through the second side groove 52, under the action of the first return spring 50, one end of the long driving rod 472 will be inserted into the second side groove 52, so that the dial block 48 abuts against the cotton inserting rod 471 and pushes one end of the cotton inserting rod 471 to slide out to the outside of the scraping strip 502. The cotton inserting rod 471 can break the coiled cotton fluffs and assist the scraping strip 502 to remove the cotton fluffs. After the long driving rod 472 passes through the second guide inclined surface 53 and leaves the second side groove, the long driving rod 472 will be pushed into the driving rod groove 28 again. At this time, the cotton inserting rod 471 will slide into the cotton rod groove 28, completing an effect of breaking the cotton fluffs once.

[0050] In addition, during the rotation of the annular sleeve 501, the baffle 46 will continuously scrape the cotton fluffs on the annular sleeve 501 to the position of the scraping strip 502. When the scraping strip 502 abuts against the baffle 46, it will drive the baffle 46 to rotate. After the scraping strip 502 passes, under the action of the torsion spring, the baffle 46 will return to the initial position.

[0051] After the cotton wadding enters the annular cavity 18 through the communication groove 20 at the position of the scraping bar 502, the cotton wadding impurities entering the annular cavity 18 can be extracted through the air duct 21 by means of an external air blower. At the same time, during the rotation of the driving roller 12, the intermittent abutting rod 60 intermittently abuts against the mating rod 61, driving the annular piston plate 561 to slide in the piston cavity through the annular push plate 563 in a cycle, so that the air guide holes 55 on the cone continuously eject gas, which helps to blow the cotton wadding impurities on the side of the annular cavity 18 far from the air duct 21 towards the side of the air duct 21.
