Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to a carding machine with a self-cleaning function. Background Technology

[0002] The carding machine is the core equipment of the textile production line. Its function is to open, remove impurities, and comb cotton fibers to form a uniform cotton sliver. During long-term high-speed operation, short fibers, neps, and impurities will inevitably adhere to the carding elements such as the cylinder, doffer, and flat cover. If these residues are not cleaned in time, they will lead to a decrease in carding quality, an increase in neps, and even a fire risk. The surface of the flat cover carding cloth is particularly difficult to clean. After long-term operation, the carding cloth will become heavily clogged with short fibers, neps, and small impurities, resulting in a decrease in carding quality. At this time, a carding machine with a self-cleaning function is needed to perform the cleaning operation.

[0003] In actual use, existing carding machines with self-cleaning functions generally use rotating brush rollers to scrape and clean the surface of the cover plate. However, the scraped-off impurities cannot be discharged in time and are prone to re-accumulating on the brush rollers or falling back into the cylinder. Although some solutions use spiral brush rollers to push impurities to one end, manual cleaning of the accumulated material is still required periodically, making continuous automated cleaning impossible. Therefore, there is an urgent need to improve the technology of carding machine structures with self-cleaning functions to perfect this equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a carding machine with a self-cleaning function. By forming a directional coupled flow field through a blow-suction coupling mechanism, the thrust of the blowing airflow and the negative pressure capturing force of the suction port work together to ensure that impurities pushed to the suction port area by the threaded paddle can be sucked in and collected immediately, avoiding secondary accumulation of impurities on the surface of the transmission roller or falling back onto the cylinder surface. At the same time, the transverse movement mechanism can control the transverse back-and-forth movement of the transmission roller to fill the axial gap between the spiral lines of the threaded paddle, so that every part of the carding cloth surface in the width direction of the cover plate assembly can be brushed and covered, thereby solving the problems mentioned in the background art in the current market.

[0006] Preferably, a first drive pulley is fixedly connected to the portion of the cylinder's central shaft extending outside the mounting base, and a first driven pulley is fixedly connected to the end of the drive roller's central shaft extending outside the mounting base.

[0007] Preferably, the transmission roller is embedded with a blower pipe, and the outer end of the transmission roller has multiple equally spaced blower holes, which are connected to the blower pipe. The end of the transmission roller extending outside the mounting base is fitted with a fixing sleeve, the inside of which has an annular groove. The bottom end of the fixing sleeve is connected to a main exhaust pipe. The inside of the transmission roller has a cavity, and the position of the transmission roller inside the fixing sleeve has a notch. The side of the transmission roller near the cavity has multiple equally spaced suction ports. A receiving frame is fixedly connected to the side wall of the movable base near the transmission roller. The side end of the receiving frame is connected to an exhaust branch pipe, which passes through the movable base and extends to the outside of the movable base. The other end of the exhaust branch pipe is connected to the main exhaust pipe.

[0008] Preferably, the blow hole is provided with a one-way valve, and the one-way valve allows one-way flow from inside the transmission roller to the outside.

[0009] Preferably, the annular groove, notch, cavity, and air intake are connected.

[0010] Preferably, the mounting base has a sliding groove near the top of the opening slot, the top of the movable base is fixedly connected to a slider, the slider is slidably connected in the sliding groove, the slider has a threaded rod threaded through it, the mounting base has a through hole near the threaded rod, the threaded rod extends into the through hole and forms a rotatable connection with the through hole, and the shaft end of the threaded rod extending outside the mounting base is fixedly connected to a drive motor.

[0011] Preferably, the cross-section of the groove and the slider is rectangular, and a polished layer is provided at the contact point between the groove and the slider.

[0012] Preferably, the central shaft of the doffer extends outside the mounting base and is rotatably connected to the mounting base. A second driving pulley is fixedly connected to the outside of the central shaft of the doffer. A second driven pulley is fixedly connected to the side end of the connecting sleeve.

A second stepper motor is fixedly connected to the end of the central shaft of the doffer extending outside the mounting base.

[0013] Preferably, the maximum lateral length of the groove is greater than the maximum lateral length of the slide.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention employs a blowing-suction coupling mechanism and a lateral movement mechanism. A controller operates a second stepper motor, which in turn drives a transmission roller via a second transmission mechanism. The threaded paddle fixed to the outer end of the transmission roller rotates accordingly. The helical structure of the paddle generates axial thrust, continuously pushing the brushed cotton fibers and impurities along the axial direction of the transmission roller. Simultaneously, an airflow is sprayed through the blowing holes onto the surface of the cover plate assembly, loosening and lifting short fibers and cotton knots embedded in the gaps of the cover plate's needle cloth. The suction port, under the negative pressure of the cavity and the main exhaust pipe, simultaneously draws in the lifted impurities, promptly sucking them into the receiving frame and discharging them through the exhaust branch pipe. The blowing and suction work in space... A directional coupled flow field is formed, and the thrust of the blowing airflow and the negative pressure capturing force of the suction port work together to ensure that impurities pushed to the suction port area by the spiral blades can be sucked in and collected immediately. This avoids the secondary accumulation of impurities on the surface of the drive rollers or their re-falling onto the cylinder surface. At the same time, the transverse movement mechanism can control the transverse back and forth movement of the drive rollers to fill the axial gap between the spiral lines of the spiral blades. This ensures that every part of the carding cloth surface in the width direction of the cover plate assembly can be brushed and covered, significantly improving the cleaning efficiency and thoroughness of the cover plate assembly. No manual intervention is required, which greatly improves the operating rate of the carding machine and the consistency of the carding quality.

[0015] This invention features a connecting sleeve and a connecting shaft. The connecting sleeve is fixedly installed outside the mounting base and fitted onto the outer end of the connecting shaft. The connecting shaft is fixedly connected to the transmission roller and moves synchronously with the transmission roller. When the controller controls the second stepper motor to work, the second stepper motor drives the second driving pulley to rotate. The second driving pulley drives the second driven pulley to rotate through the second synchronous toothed belt, thereby driving the connecting sleeve to rotate. When the lateral movement mechanism drives the transmission roller to reciprocate axially, the connecting shaft moves together with the transmission roller, and the vertical rod slides freely in the groove. This ensures that the transmission roller is not interfered with or constrained by the connecting sleeve during axial reciprocating motion, achieving continuous and stable rotational power for the transmission roller during axial reciprocating motion. This guarantees the continuity of brushing rotation during cleaning operations and also achieves flexibility in axial reciprocating coverage, making it convenient to use.

[0016] This invention establishes a first transmission mechanism, in which a controller controls the first stepper motor to rotate. The first stepper motor drives the central shaft of the cylinder to rotate, and the first driving pulley on the central shaft of the cylinder drives the first driven pulley and the driving roller to rotate synchronously via a first synchronous toothed belt, thereby realizing the linkage drive between the cylinder and the cover plate assembly. When the controller controls the drive motor to work, the drive motor drives the threaded rod to rotate. The threaded rod engages with the slider threadedly, converting the rotational motion of the threaded rod into the linear reciprocating motion of the slider along the slide groove. The slider drives the moving seat and the transmission roller to move synchronously. Through the connecting sleeve and the connecting shaft, the transmission roller can rotate while also moving laterally back and forth. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Please see Figures 1 to 6 The present invention provides a technical solution: a carding machine with self-cleaning function, including a carding machine 1, a base 2 at the bottom of the carding machine 1, a mounting seat 3 fixedly connected to the top of the base 2, a feed roller 4, a licker-in roller 5, a cylinder 6 and a doffer 7 rotatably connected inside the mounting seat 3, a cover plate assembly 8 inside the mounting seat 3, the cover plate assembly 8 being located above the cylinder 6, a drive roller 9 and a driven roller 10 inside the cover plate assembly 8, and a first transmission mechanism on the outer side of the mounting seat 3, the first transmission mechanism being able to control the cylinder 6 and the drive roller 9 to rotate simultaneously; Both sides of the mounting base 3 have opening slots 15, and a movable seat 16 is slidably connected in the opening slots 15. A transmission roller 17 is rotatably connected to the inner wall of the movable seat 16. A threaded paddle 18 is fixedly connected to the outer end of the transmission roller 17. The mounting base 3 is equipped with a blow-suction coupling mechanism, which enables the transmission roller 17 to perform blow-suction coupling operations on the surface of the cover plate assembly 8 when it rotates. The mounting base 3 is equipped with a transverse moving mechanism, which controls the transmission roller 17 to move back and forth laterally. A connecting shaft 39 is fixedly connected to one end of the transmission roller 17 that extends outside the movable seat 16. A connecting sleeve 38 is provided on the outside of the mounting base 3 at the position corresponding to the connecting shaft 39. The connecting sleeve 38 is sleeved on the outside of the connecting shaft 39. Both the upper and lower ends of the connecting sleeve 38 have grooves 40. Both the upper and lower ends of the connecting shaft 39 are fixedly connected to vertical rods 41, which are located in the grooves 40. A second transmission mechanism is provided on the outside of the mounting base 3, which controls the doffer 7 and the transmission roller 17 to rotate simultaneously.

[0021] By setting up a blow-suction coupling mechanism and a lateral movement mechanism, the controller controls the second stepper motor 37 to work, which in turn drives the transmission roller 17 to rotate via the second transmission mechanism. The threaded paddle 18 fixed at the outer end of the transmission roller 17 rotates accordingly. The spiral structure of the threaded paddle 18 generates axial thrust, continuously pushing the brushed cotton fibers and impurities along the axial direction of the transmission roller 17. At the same time, the blower pipe 19 sprays airflow through the blower hole 20 onto the surface of the cover plate assembly 8, loosening and lifting the short fibers and cotton knots embedded in the gaps of the cover plate needle cloth. The suction port 26 simultaneously draws in the impurities under the negative pressure of the cavity 24 and the exhaust manifold 23, promptly sucking them into the receiving frame 27 and discharging them through the exhaust branch pipe 28. The blowing and suction... The wind forms a directional coupled flow field in space. The thrust of the blowing airflow and the negative pressure capturing force of the suction port 26 work together to ensure that impurities pushed to the area of ​​the suction port 26 by the threaded paddle 18 can be sucked in and collected in time. This avoids the secondary accumulation of impurities on the surface of the transmission roller 17 or their re-falling onto the surface of the cylinder 6. At the same time, the transmission roller 17 can be controlled to move back and forth laterally through the lateral movement mechanism, filling the axial gap between the spiral lines of the threaded paddle 18. This ensures that every part of the carding cloth surface in the width direction of the cover plate assembly 8 can be brushed and covered, significantly improving the cleaning efficiency and thoroughness of the cover plate assembly 8. No manual intervention is required, which greatly improves the operating rate of the carding machine 1 and the consistency of the carding quality.

[0022] Please see Figures 2 to 3 The central shaft of cylinder 6 extends to the outside of mounting base 3 and is fixedly connected to a first drive pulley 11. The end of the central shaft of drive roller 9 extends to the outside of mounting base 3 and is fixedly connected to a first driven pulley 12. A first synchronous toothed belt 13 is sleeved on the outside of the first drive pulley 11 and the first driven pulley 12. A first stepper motor 14 is fixedly connected to the end of the central shaft of cylinder 6.

[0023] The controller controls the first stepper motor 14 to work. The first stepper motor 14 drives the central shaft of the cylinder 6 to rotate. The first drive pulley 11 on the central shaft of the cylinder 6 drives the first driven pulley 12 and the drive roller 9 to rotate synchronously through the first synchronous toothed belt 13.

[0024] Please see Figures 3 to 6 A blower pipe 19 is embedded in the drive roller 17. Multiple equally spaced blower holes 20 are opened at the outer end of the drive roller 17, and the blower holes 20 are connected to the blower pipe 19. A fixing sleeve 21 is fitted onto the end of the drive roller 17 extending outside the mounting base 3. An annular groove 22 is opened inside the fixing sleeve 21. The bottom end of the fixing sleeve 21 is connected to a main exhaust pipe 23. A cavity 24 is opened inside the drive roller 17. A notch 25 is opened at the position of the drive roller 17 within the fixing sleeve 21. The drive roller 17 is close to the cavity 24. Multiple equally spaced air inlets 26 are provided on one side of the movable seat 16. A receiving frame 27 is fixedly connected to the side wall of the movable seat 16 near the transmission roller 17. An exhaust branch pipe 28 is connected to the side end of the receiving frame 27. The exhaust branch pipe 28 passes through the movable seat 16 and extends to the outside of the movable seat 16. The other end of the exhaust branch pipe 28 is connected to the exhaust main pipe 23. A one-way valve is provided in the air blowing hole 20. The one-way valve allows one-way flow from the inside of the transmission roller 17 to the outside. The annular groove 22, the notch 25, the cavity 24 and the air inlet 26 are connected.

[0025] The blower pipe 19 sprays airflow through the blower hole 20 onto the surface of the cover plate assembly 8, loosening and lifting the short fibers and cotton knots embedded in the gaps of the cover plate needle cloth. The suction port 26 simultaneously draws in the air under the negative pressure of the cavity 24 and the exhaust main pipe 23, promptly sucking in the collected frame 27 and discharging it through the exhaust branch pipe 28. The blowing and suction form a directional coupled flow field in space. The thrust of the blowing airflow and the negative pressure capturing force of the suction port 26 work together to ensure that the impurities pushed to the area of ​​the suction port 26 by the threaded paddle 18 can be sucked in and collected immediately, avoiding secondary accumulation of impurities on the surface of the drive roller 17 or falling back onto the surface of the cylinder 6. At the same time, by setting a one-way valve, dust and impurities can be prevented from entering the blower hole 20 and causing blockage.

[0026] Please see Figure 3 and Figure 5 The mounting base 3 has a sliding groove 29 at the top near the opening slot 15. The top of the movable base 16 is fixedly connected to a slider 30, which is slidably connected in the sliding groove 29. A threaded rod 31 is threaded through the slider 30. A through hole 32 is provided in the mounting base 3 on the side near the threaded rod 31. The threaded rod 31 extends into the through hole 32 and forms a rotatable connection with the through hole 32. A drive motor 33 is fixedly connected to the shaft end of the threaded rod 31 extending outside the mounting base 3. The cross-section of the sliding groove 29 and the slider 30 is rectangular. A polished layer is provided at the contact point between the sliding groove 29 and the slider 30.

[0027] The controller controls the drive motor 33 to work, and the drive motor 33 drives the threaded rod 31 to rotate. The threaded rod 31 is threadedly engaged with the slider 30, converting the rotational motion of the threaded rod 31 into the linear reciprocating motion of the slider 30 along the slide groove 29. The slider 30 drives the moving seat 16 and the transmission roller 17 to move synchronously. Through the connecting sleeve 38 and the connecting shaft 39, the transmission roller 17 can rotate while also moving laterally back and forth. Furthermore, the contact area between the slide groove 29 and the slider 30 is provided with a polished layer, which allows the slider 30 to slide smoothly in the slide groove 29 and avoid jamming.

[0028] Please see Figures 1 to 3 The central shaft of the doffer 7 extends to the outside of the mounting base 3 and is rotatably connected to the mounting base 3. A second driving pulley 34 is fixedly connected to the outside of the central shaft of the doffer 7. A second driven pulley 35 is fixedly connected to the side end of the connecting sleeve 38. A second synchronous toothed belt 36 is sleeved on the outside of the second driving pulley 34 and the second driven pulley 35. A second stepper motor 37 is fixedly connected to the end of the central shaft of the doffer 7 extending to the outside of the mounting base 3. The maximum lateral length of the groove 40 is greater than the maximum lateral length of the slide groove 29.

[0029] The controller controls the second stepper motor 37 to work. The second stepper motor 37 drives the second drive pulley 34 to rotate. The second drive pulley 34 drives the second driven pulley 35 to rotate through the second synchronous toothed belt 36, thereby driving the transmission roller 17 to rotate. The threaded paddle 18 fixed at the outer end of the transmission roller 17 rotates accordingly. The spiral structure of the threaded paddle 18 generates axial thrust, continuously pushing the brushed cotton and impurities along the axial direction of the transmission roller 17.

[0030] Working principle: When this carding machine with self-cleaning function is in use, firstly, the controller controls the first step motor 14 to work. The first step motor 14 drives the central shaft of the cylinder 6 to rotate. The first drive pulley 11 on the central shaft of the cylinder 6 drives the first driven pulley 12 and the drive roller 9 to rotate synchronously through the first synchronous toothed belt 13, thereby realizing the linkage drive between the cylinder 6 and the cover plate assembly 8. The cotton feeding roller 4 feeds the cotton layer into the area of ​​the licker-in roller 5. After the licker-in roller 5 performs preliminary opening and impurity removal on the cotton layer, it transfers the cotton fibers to the surface of the cylinder 6. The cylinder 6 carries the cotton fibers at high speed. When it passes under the cover plate assembly 8, the carding cloth on the surface of the cylinder 6 and the cover plate carding cloth on the lower surface of the cover plate assembly 8 form a carding configuration. The cotton fibers are repeatedly gripped, carded and stretched between the two and separated into single fiber state. The carded cotton fibers are condensed and output from the surface of the cylinder 6 by the doffer 7 to form a uniform cotton sliver. While the carding machine 1 is operating normally, the second stepper motor 37 drives the central shaft of the doffer 7 to rotate. The second driving pulley 34 on the central shaft of the doffer 7 drives the second driven pulley 35 to rotate synchronously through the second synchronous toothed belt 36. The second driven pulley 35 is fixedly connected to the side end of the connecting sleeve 38. The connecting sleeve 38 is sleeved on the outside of the connecting shaft 39. The grooves 40 at the upper and lower ends of the connecting sleeve 38 engage with the vertical rods 41 at the upper and lower ends of the connecting shaft 39. The rotational torque of the connecting sleeve 38 is transmitted to the connecting shaft 39 through the contact between the grooves 40 and the vertical rods 41, thereby driving the transmission roller 17 to rotate continuously. During the rotation of the drive roller 17, the threaded paddle 18 fixed at its outer end rotates accordingly. The spiral structure of the threaded paddle 18 scrapes and pushes the impurities on the surface of the cover plate assembly 8. At the same time, compressed air is sent into the interior of the drive roller 17 through the blow pipe 19 and sprayed out through the blow hole 20. The one-way valve set in the blow hole 20 ensures that the airflow flows only from the interior of the drive roller 17 to the outside in one direction. The compressed airflow sprayed out impacts the cover plate needle cloth on the surface of the cover plate assembly 8 at a certain angle, loosening and lifting the short fibers, cotton knots and fine impurities embedded deep in the tooth gaps of the cover plate needle cloth. While the air is being blown out of the blower 20, the exhaust manifold 23 is connected to an external negative pressure source. The negative pressure enters the annular groove 22 inside the fixed sleeve 21 through the exhaust manifold 23. Since the annular groove 22 is circumferentially opened along the inner wall of the fixed sleeve 21, the notch 25 of the drive roller 17 inside the fixed sleeve 21 always remains connected to the annular groove 22, regardless of the angle to which the drive roller 17 rotates. The negative pressure enters the cavity 24 inside the drive roller 17 through the notch 25, and is then drawn outward by multiple suction ports 26 opened on the side of the drive roller 17 near the cavity 24. The suction ports 26 generate negative pressure downstream of the airflow from the blower 20, which promptly draws the impurities blown up by the blower 20 into the cavity 24. The impurities are then discharged into the dust collection system after entering the exhaust manifold 23 with the airflow through the notch 25 and the annular groove 22. The airflow from the blower 20 and the negative pressure from the suction ports 26 form a directional coupled flow field near the surface of the cover plate assembly 8. While the transmission roller 17 continues to rotate and clean, the controller controls the drive motor 33 to work. The drive motor 33 drives the threaded rod 31 to rotate. The threaded rod 31 and the slider 30 are threaded together, converting the rotational motion of the threaded rod 31 into the linear reciprocating motion of the slider 30 along the slide groove 29. The slider 30 drives the moving seat 16 and the transmission roller 17 to move synchronously, filling the axial gap between the spiral lines of the threaded paddle 18. This ensures that every part of the carding cloth surface in the width direction of the cover plate assembly 8 can be brushed and covered, significantly improving the cleaning efficiency and thoroughness of the cover plate assembly 8. No manual intervention is required, which greatly improves the operating rate of the carding machine 1 and the consistency of the carding quality. The cleaned impurities are discharged out of the machine through the exhaust manifold 23. The cover plate assembly 8 continuously passes through the cleaning area during its rotational motion. Each cover plate is cleaned in a timely and thorough manner after leaving the working area and re-enters the working area to participate in the carding operation in a clean state. This cycle repeats continuously, realizing the continuous automated self-cleaning of the cover plate carding cloth without stopping the carding machine 1.
