Description

Technical Field

[0001] This invention relates to the field of carding machine technology, specifically a carding machine with cotton lint removal function. Background Technology

[0002] The carding machine is a core piece of equipment in textile machinery used for processing cotton and chemical fibers. Located between the opening and cleaning machine and the drawing frame (or sliver lap), it performs the functions of opening, carding, removing impurities, and forming slivers. The working principle of the carding machine is to open, card, and remove impurities from the cotton (fiber) laps sent from the previous process or the oily cotton (chemical fiber) layer supplied by the cotton box, so that all the curled and lumpy cotton loops become basically straight single fibers. In this process, broken seeds, impurities, and short fibers left over from the cleaning process are removed. Then, the cotton is assembled into slivers of a certain specification and stored in cotton bolls for use in the drawing process.

[0003] However, existing carding machines often produce a lot of cotton lint in the working environment, which may have an adverse effect on the health of operators. At the same time, the corresponding dust removal equipment is prone to clogging when filtering out cotton lint.

Detailed Implementation

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 11 As shown, the carding machine with cotton lint removal function of the present invention includes a carding machine body 1, a dust removal structure 2 on the top side of the carding machine body 1, a cleaning structure 6 on the inner side of the dust removal structure 2, a collection structure 3 connected between the cleaning structure 6 and the dust removal structure 2, a feeding structure 4 at the end of the carding machine body 1, a winding structure 5 connected to the side of the carding machine body 1, and a lifting structure 7 connected to the winding structure 5.

[0040] Specifically, such as Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the dust removal structure 2 includes a dust collection box 201. The dust collection box 201 is installed on the top side of the carding machine body 1. A dust collection port 210 is opened on the side of the dust collection box 201. An exhaust fan 202 is installed on the top side of the dust collection box 201. A first roller shaft 205 and a second roller shaft 206 are rotatably connected to the inner side of the dust collection box 201. A filter screen 203 is sleeved between the first roller shaft 205 and the second roller shaft 206. A cleaning roller 204 is provided on the side of the filter screen 203. A second pulley 209 is provided at the end of the cleaning roller 204. The second pulley 209 is rotatably connected to the dust collection box 201. A first pulley 207 is fixedly connected to the end of the first roller shaft 205. A transmission belt 208 is sleeved between the first pulley 207 and the second pulley 209.

[0041] The exhaust fan 202 on the top side can suck out light debris such as cotton lint generated inside the carding machine body 1. After the cotton lint enters the dust collection box 201, it will be filtered by the filter screen 203. The filter screen 203 rotates around the first roller shaft 205 and the second roller shaft 206. The first roller shaft 205 is driven to rotate by the motor, so that the filter screen 203 can continuously change its filtration position while performing the filtration effect. On the other hand, while the first roller shaft 205 is rotating, it will drive the second pulley 209 to rotate through the first pulley 207 and the transmission belt 208. The second pulley 209 is connected to the cleaning roller 204. While the cleaning roller 204 is rotating, it will clean the surface of the filter screen 203, thereby maintaining the filtration effect of the filter screen 203, removing the cotton lint attached to the surface of the filter screen 203 in time, and maintaining the dust removal effect of the device.

[0042] Specifically, such as Figure 3 , Figure 7 , Figure 8 , Figure 9 As shown, multiple driven bars 602 are slidably connected to the inner side of the cleaning roller 204. The multiple driven bars 602 are arranged in a ring on the side of the cleaning roller 204. Multiple cleaning needles 603 are vertically fixedly connected to the side of the driven bars 602. Multiple through holes 604 are provided on the side of the cleaning roller 204 corresponding to the cleaning needles 603. The cleaning needles 603 are slidably connected to the cleaning roller 204 through the through holes 604. A seventh spring 606 is fixedly connected between the driven bars 602 and the cleaning roller 204. An inner slide rod 601 is slidably connected to the middle of the cleaning roller 204. A sixth spring 605 is fixedly connected between the end of the inner slide rod 601 and the cleaning roller 204. An inclined groove 607 is provided on the side of the inner slide rod 601. A protruding structure is provided on the side of the driven bars 602. The protruding structure on the side of the driven bars 602 is slidably connected to the inner slide rod 601 through the inclined groove 607 provided on the same side.

[0043] Since cotton lint is fibrous, multiple driven strips 602 are provided on the inner side of the cleaning roller 204 to improve the cleaning effect. When the driven strips 602 move, the cleaning needles 603 on their sides are pushed out from the perforations 604. At this time, as the cleaning roller 204 rotates, the extended part of the cleaning needles 603 will fully pull off the cotton lint attached to the surface of the filter screen 203 and wrap it around the cleaning roller 204, so that the filter screen 203 can maintain a good filtration effect and air permeability. As for the separated cotton lint, the inner sliding rod 601 at the end of the cleaning roller 204 can be slid to make the protrusion on the side of the driven strip 602 slide along the inner inclined groove 607. At this time, the cleaning needles 603 can be retracted into the interior of the cleaning roller 204 by the inclined surface. In this way, it is convenient for the operator to clean the cotton lint wrapped on the cleaning roller 204, which is convenient to use.

[0044] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 As shown, the collection structure 3 includes a switching rod 309. The switching rod 309 is rotatably connected to the side of the dust collection box 201. A limiting groove 308 is formed on the side of the dust collection box 201. The switching rod 309 is slidably connected to the dust collection box 201 through the limiting groove 308. A cleaning roller 204 is provided at each end of the switching rod 309. The end of the cleaning roller 204 has a square structure. A connecting sleeve 306 is slidably connected to the end of the second pulley 209. The connecting sleeve 306 is slidably connected to the square end of the cleaning roller 204. The connecting sleeve 306 is connected to the second pulley 209. A second spring 307 is fixedly connected between the two. A traction block 304 is rotatably connected to the end of the connecting sleeve 306. The traction block 304 is slidably connected to the dust collection box 201. The end of the inner slide rod 601 has a hemispherical structure. A side cover 301 is rotatably connected to the side of the dust collection box 201. A pull block 302 is slidably connected to the side cover 301. A first spring 305 is fixedly connected between the pull block 302 and the side cover 301. A locking groove 303 is provided on the dust collection box 201. The end of the pull block 302 is locked to the dust collection box 201 through the locking groove 303.

[0045] To facilitate the removal of lint from the cleaning roller 204, two cleaning rollers 204 are installed on the switching lever 309 located on the side of the vacuum box 201. When a large amount of lint accumulates on the cleaning roller 204, the user can pull the traction block 304 located on the side of the vacuum box 201. The traction block 304 will cause the connecting sleeve 306 to slide outward, simultaneously disengaging the current cleaning roller 204 from the connecting sleeve 306. Then, the switching lever 309 is rotated, causing the other cleaning roller 204 to rotate to the current position. The traction block 304 is then released. As the second pulley 209 rotates, the square portion at the end of the cleaning roller 204 will re-engage with the connecting sleeve 306. Simultaneously, due to the connection... The inner side of the sleeve 306 is hollow, which allows the inner slide rod 601 to be extended, thus ensuring that the cleaning needle 603 is also extended to clean the adjacent filter 203. As for the cleaning roller 204 that rotates out on the other side, the extended part of the inner slide rod 601 at its end will slide inward due to the abutment between it and the inner wall of the dust box 201. At this time, the cleaning needle 603 on the cleaning roller 204 will be retracted. Since the cleaning roller 204 will rotate to the inside of the side cover 301, the user can open the side cover 301 by pulling the pull block 302 and then quickly remove the cotton lint wrapped on the cleaning roller 204 for easy collection and processing.

[0046] Specifically, such as Figure 1 , Figure 10 As shown, the feeding structure 4 includes a feeding cylinder 401. The feeding cylinder 401 is installed at the end of the carding machine body 1. A guide plate 402 is rotatably connected to each side of the feeding cylinder 401. A first groove 403 is provided on the side of the guide plate 402. A traction rod 404 is slidably connected to the side of the feeding cylinder 401. The two ends of the traction rod 404 are slidably connected to the guide plate 402 on the same side through the first groove 403. The traction rod 404 has a "+" shaped structure. A second groove 405 is provided on the side of the traction rod 404. A drive disc 406 is rotatably connected to the side of the feeding cylinder 401. A sliding column 407 is fixedly connected to the side of the drive disc 406. The sliding column 407 is slidably connected to the traction rod 404 through the second groove 405.

[0047] After the cotton material is added to the feed cylinder 401, the drive disc 406 on the side is rotated by the motor. At this time, the eccentrically set sliding column 407 on the side of the drive disc 406 will slide in the second sliding groove 405 on the side of the traction slide rod 404, and drive the traction slide rod 404 to slide back and forth on the side of the feed cylinder 401. The two ends of the traction slide rod 404 further slide in the first sliding groove 403 on the guide plates 402 on both sides, and finally drive the two guide plates 402 to evenly sprinkle the input cotton material, thereby achieving the effect of uniform feeding.

[0048] Specifically, such as Figure 1 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the winding structure 5 includes a mounting frame 501. The mounting frame 501 is located on the side of the carding machine body 1. A winding roller 502 is rotatably connected to the mounting frame 501. A drive screw 507 is rotatably connected to each side of the mounting frame 501. A lifting plate 504 is located in the middle of the mounting frame 501. A threaded block 506 is located on each side of the lifting plate 504. The threaded block 506 is threadedly connected to the drive screw 507 located on the same side. A connecting frame 505 is slidably connected to the bottom side of the lifting plate 504. A fifth spring 512 is fixedly connected between the connecting frame 505 and the lifting plate 504. A pressure roller 503 is rotatably connected to the connecting frame 505. A third spring 508 is fixedly connected between the threaded block 506 and the lifting plate 504. A ratchet 509 is fixedly connected to the top of the drive screw 507. A ratchet block 510 is slidably connected to the inner side of the mounting frame 501. A fourth spring 511 is fixedly connected between the ratchet block 510 and the mounting frame 501. The ratchet 509 and the ratchet block 510 mesh with each other.

[0049] In order to ensure that the cotton yarn can be wound up evenly, a pressure roller 503 is provided on the bottom side of the lifting plate 504 on the mounting frame 501. The pressure roller 503 can apply a certain pressure to the wound cotton yarn, making the cotton yarn more compact while maintaining a full fluffy effect. Depending on the thickness of the wound cotton yarn, the position of the pressure roller 503 can be adjusted by rotating the drive screw 507 to achieve different squeezing effects.

[0050] Specifically, such as Figure 11 , Figure 12 , Figure 15 As shown, the lifting structure 7 includes a drive gear 701. The end of the take-up roller 502 is fixedly connected to the drive gear 701. A transmission gear 702 meshes with the side of the drive gear 701. The transmission gear 702 is rotatably connected to the mounting bracket 501. A first bevel gear 703 is fixedly connected to the side of the transmission gear 702. A second bevel gear 704 meshes with the side of the first bevel gear 703. The second bevel gear 704 is fixedly connected to a drive screw 507 on the same side. An adjusting rod 705 is slidably connected to the middle of the lifting plate 504. A contact block 706 is rotatably connected to the middle of the lowering plate 504. A contact groove 707 is provided on the side of the contact block 706. The end of the threaded block 506 abuts against the side of the contact block 706. An adjusting rod 705 is slidably connected to the middle of the contact block 706. An eighth spring 710 is fixedly connected between the adjusting rod 705 and the lifting plate 504. A positioning post 708 is fixedly connected to the side of the adjusting rod 705. The lifting plate 504 is provided with four positioning grooves 709. The positioning post 708 is engaged with the lifting plate 504 through the positioning grooves 709.

[0051] To automatically adjust the position of the pressure roller 503 according to the degree of cotton yarn winding, the winding roller 502 rotates while its end drives the transmission gear 702 to rotate via the drive gear 701. The drive gear 701 has only one tooth structure on its side, making the rotation of the transmission gear 702 relatively slow, thus slowly adjusting the height of the pressure roller 503. The transmission gear 702, through the transmission effect of the first bevel gear 703 and the second bevel gear 704, drives the drive screws 507 on both sides to rotate slowly. At the same time, to prevent the drive screws 507 from rotating backward, a ratchet 509 and a ratchet block 510 are provided on its top, which slowly adjusts the height of the lifting plate 504 by following the winding of the cotton yarn. The lifting mechanism, combined with the fifth spring 512, ensures that the pressure roller 503 always applies appropriate pressure to the cotton yarn, guaranteeing a good winding effect. After winding is complete, the user can pull the adjusting rod 705 in the middle of the lifting plate 504 to release the engagement between the positioning post 708 and the current positioning groove 709. Then, rotate the adjusting rod 705 90° and release it. At this time, the inner abutting block 706 will rotate the side abutting groove 707 to both sides, allowing the end of the threaded block 506 to abut against the abutting block 706 through the abutting groove 707. At this time, the threaded part at the end of the threaded block 506 will disengage from the drive screw 507. The user can then freely adjust the position of the lifting plate 504 for convenient use.

[0052] In use, this invention firstly uses a top-mounted exhaust fan 202 to draw out lightweight impurities such as cotton lint generated inside the carding machine body 1. After entering the dust collection box 201, the cotton lint is filtered by a filter screen 203. The filter screen 203 rotates around a first roller shaft 205 and a second roller shaft 206. A motor drives the first roller shaft 205 to rotate, allowing the filter screen 203 to continuously change its filtration position while maintaining its filtration effect. Simultaneously, the rotation of the first roller shaft 205 drives a second roller 209 to rotate via a first pulley 207 and a transmission belt 208. A cleaning roller 204 is connected to the second roller 209, and its rotation cleans the surface of the filter screen 203, thus maintaining its filtration efficiency. To effectively remove lint from the surface of the filter screen 203 and maintain the dust removal efficiency of the device, multiple driven strips 602 are provided on the inner side of the cleaning roller 204 to enhance the cleaning effect, since lint is fibrous. When the driven strips 602 move, the cleaning needles 603 on their sides are pushed out from the perforations 604. As the cleaning roller 204 rotates, the extended parts of the cleaning needles 603 fully pull off the lint adhering to the surface of the filter screen 203 and wrap it around the cleaning roller 204, thus maintaining a good filtration effect and air permeability for the filter screen 203. The separated lint can be removed by sliding the inner slide rod 601 at the end of the cleaning roller 204, causing the protrusions on the side of the driven strips 602 to slide along the internal inclined grooves 607. When the angled surface is activated, the cleaning needle 603 can be retracted into the cleaning roller 204, making it convenient for the operator to clean the lint entangled on the cleaning roller 204. To facilitate the removal of lint from the cleaning roller 204, two cleaning rollers 204 are installed on the switching lever 309 located on the side of the vacuum box 201. When a large amount of lint accumulates on the cleaning roller 204, the user can pull the traction block 304 located on the side of the vacuum box 201. The traction block 304 will cause the connecting sleeve 306 to slide outward, simultaneously disengaging the current cleaning roller 204 from the connecting sleeve 306. Then, rotating the switching lever 309 will rotate the other cleaning roller 204 to the current position, and then releasing the traction block. 304. As the second pulley 209 rotates, the square portion at the end of the cleaning roller 204 will re-engage with the connecting sleeve 306. Simultaneously, because the inner side of the connecting sleeve 306 is hollow, the inner slide rod 601 is extended, ensuring that the cleaning needles 603 are also extended for cleaning the adjacent filter screen 203. For the cleaning roller 204 that rotates out on the other side, the extended portion of the inner slide rod 601 at its end will slide inward due to its contact with the inner wall of the dustbin 201. At this time, the cleaning needles 603 on the cleaning roller 204 will be retracted. Furthermore, because the cleaning roller 204 will rotate to the inside of the side cover 301, the user can open the side cover 301 by pulling the lever 302.Then, quickly remove the cotton lint wrapped around the cleaning roller 204 to facilitate the collection and processing of the cleaned cotton lint. A feed cylinder 401 is provided on the feed inlet located on the side of the carding machine body 1. After the cotton material is added to the feed cylinder 401, the drive disc 406 on the side is rotated by the motor. At this time, the sliding column 407 eccentrically set on the side of the drive disc 406 will slide in the second sliding groove 405 on the side of the traction slide rod 404, and drive the traction slide rod 404 to slide back and forth on the side of the feed cylinder 401. The two ends of the traction slide rod 404 further slide in the first sliding groove 403 on the guide plates 402 on both sides, and finally drive the two guide plates 402 to evenly distribute the input cotton material. To achieve uniform feeding, a take-up roller 502 is located at the end of the carding machine body 1 to take up the final yarn. The take-up roller 502 is driven by a motor. To ensure uniform yarn take-up, a pressure roller 503 is located on the bottom side of the lifting plate 504 on the mounting frame 501. The pressure roller 503 applies pressure to the taken-up yarn, making the yarn tighter while maintaining sufficient fluffiness. Depending on the thickness of the yarn taken up, the position of the pressure roller 503 can be adjusted by rotating the drive screw 507 to achieve different compression effects. To automatically adjust the position of the pressure roller 503 according to the degree of yarn take-up, the pressure roller 503 is adjusted accordingly. The height of the pressure roller 503 is adjusted as the take-up roller 502 rotates. Simultaneously, its end drives the transmission gear 702 via the drive gear 701. The drive gear 701 has only one toothed structure on its side, causing the transmission gear 702 to rotate relatively slowly, thus gradually adjusting the height of the pressure roller 503. The transmission gear 702, through the transmission effect of the first bevel gear 703 and the second bevel gear 704, drives the drive screws 507 on both sides to rotate slowly. To prevent the drive screws 507 from rotating backward, a ratchet 509 and a ratchet block 510 are provided at their top. This slowly raises the height of the lifting plate 504 by following the take-up of the cotton yarn, combined with the fifth spring. 512 ensures that the pressure roller 503 consistently applies appropriate pressure to the cotton yarn, guaranteeing a good winding effect. After winding is complete, the user can pull the adjusting rod 705 in the middle of the lifting plate 504 to release the engagement between the positioning post 708 and the current positioning groove 709. Then, rotating the adjusting rod 705 90° and releasing it causes the inner abutment block 706 to rotate the side abutment groove 707 to both sides, allowing the end of the threaded block 506 to abut against the abutment block 706 through the abutment groove 707. At this point, the threaded portion at the end of the threaded block 506 disengages from the drive screw 507, allowing the user to freely adjust the position of the lifting plate 504 for convenient use.
