Description

Technical Field

[0001] This invention relates to the field of cotton yarn carding technology, specifically a cotton yarn carding device for cotton yarn production. Background Technology

[0002] Carding machines are used to process cotton fibers and chemical fibers. They belong to textile machinery. According to the spinning process, carding is an important step. Its working principle is to open, comb, and remove impurities from the cotton (fiber) rolls sent from the previous process or the oily cotton (chemical fiber) layer supplied by the cotton box. This makes all the curled and lumpy cotton loops into 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 integrated into slivers of a certain specification and stored in cotton bobbins for use in the drawing process.

[0003] Further description is needed: fibers and impurities are combed and carried away by the saw teeth of the carding roller, and then rotate. During the rotation, some fibers and impurities will leave the saw teeth and be suspended in the boundary layer, and move forward with the airflow in the boundary layer. Utilizing the movement law of fibers and impurities in the boundary layer (impurities have large mass and low resistance, while fibers have light mass and high resistance), the boundary layer is cut differently by the dust removal knife to achieve the purpose of regulating cotton waste, removing impurities and retaining fibers. At the same time, the speed of the carding roller, cylinder and flat plate in the carding machine are different, and their speed needs to be adjusted separately according to the actual situation, so that the carding machine cannot complete the operation with a single motor.

[0004] A search revealed that Chinese patent CN219886255U discloses a carding device for cotton yarn production. While it can clean the brush rollers and collect dust from the cleaning chamber, it cannot account for the differences in rotational speed between the rollers. It cannot meet the needs of multiple roller speeds using a single motor, thus requiring the involvement of multiple motors and electrical controls. This not only increases costs and the risk of equipment damage but also complicates electrical control and makes yarn routing difficult. Furthermore, when the cotton yarn feeding efficiency is increased, the rotational speeds of the licker-in roller and cylinder should also be increased to ensure efficient and stable carding. However, increasing the rotational speeds of the licker-in roller and cylinder leads to changes in airflow intensity and direction, which may affect fiber combing and impurity removal. To maintain stable and efficient airflow within the device, the suction efficiency needs to be increased. Summary of the Invention

[0010] As a further embodiment of the present invention: the second driven sprocket and the driving gear are both rotatably sleeved with the side wall of the machine body, and the driven gear is fixedly sleeved with the rotating shaft on the licker roller.

[0011] As a further embodiment of the present invention: a fan housing is fixedly connected to the side wall of the machine body, a rotating shaft is rotatably sleeved on the central axis of the fan housing, blades are fixedly connected to both ends of the rotating shaft, and a third driven sprocket is fixedly sleeved on the outer surface of the rotating shaft. One end of a third chain is meshed and sleeved on the outer surface of the third driven sprocket, and a second transmission sprocket is meshed and sleeved on the other end of the third chain. A driven helical gear is fixedly connected to the end face of the second transmission sprocket, and a driving helical gear is meshed and connected to the outer surface of the driven helical gear.

[0012] As a further embodiment of the present invention: the worm gear is meshed with the worm, the third chain is slidably sleeved with the fan housing, and the third chain is slidably sleeved with the side wall of the machine body.

[0013] As a further embodiment of the present invention: the second transmission sprocket and the second transmission shaft are both rotatably sleeved with the side wall of the machine body, and the blades at both ends of the shaft are symmetrically arranged about the bisecting plane of the fan casing.

[0014] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows: This invention uses a sliding cavity and guide block to drive the collar to rotate, which in turn causes the toothed block on the collar to drive the fixed toothed ring to rotate. This causes the connecting shaft on the fixed toothed ring to rotate, which in turn causes the connecting shaft to drive the cylinder to rotate. If it is necessary to adjust the speed ratio between the cylinder and the feed roller, the screw outside the machine body is rotated, causing the screw to rotate and enter the machine body. At this time, the screw will push the guide block to translate along the sliding cavity, causing the collar on the guide block to drive the toothed block to translate. This causes the toothed block to be squeezed by the side wall of the ring cavity, and the inner diameter of the ring cavity gradually decreases. As a result, the toothed block is gradually compressed and shrinks into the groove, compressing the return spring. At this time, the effective radius of the toothed block's rotation decreases, while the effective radius of the fixed toothed ring meshing with the toothed block increases. According to the formula of linear velocity and radius... It is known that when the angular velocity of the rotating shaft, i.e. the angular velocity of the feed roller, is constant, the smaller the radius, the smaller the linear velocity. Therefore, the linear velocity of the contracted tooth block decreases, which in turn decreases the linear velocity of the fixed tooth ring driven by the tooth block. According to the above formula, if the linear velocity decreases and the radius increases, the angular velocity must decrease. Therefore, the speed of the cylinder driven by the connecting shaft decreases, and vice versa. Thus, the speed ratio between each roller can be freely adjusted according to the needs, and the differences in speed between each roller can be fully considered. In this way, the needs of multiple roller speeds can be met by the same motor, without the need for multiple motors and electrical control. This not only reduces the cost and the risk of equipment damage, but also simplifies the electrical control and wiring.

[0015] This invention increases the rotational speed of the feed roller via a first drive shaft. Simultaneously, the first drive shaft, through the aforementioned process, increases the rotational speed of the connecting shaft, thereby increasing the rotational speed of the worm gear on the connecting shaft. This, in turn, increases the rotational speed of the worm wheel via the worm gear, which in turn accelerates the rotation of the driving helical gear via a second drive shaft. This, in turn, accelerates the rotation of the second drive sprocket via a third chain, which in turn accelerates the rotation of the third driven sprocket and the rotating shaft. This causes the blades on the rotating shaft to rotate faster, thus increasing the suction efficiency of the blades. The airflow is then transmitted into the machine body through a duct, achieving the purpose of increasing suction efficiency and maintaining stable and efficient airflow within the device. This ensures efficient and stable carding, guaranteeing the fiber combing and impurity removal effects.

[0016] This invention drives a second driven sprocket to rotate via a first transmission sprocket and a second chain. This causes the driving gear on the second driven sprocket to drive the driven gear to rotate. At this time, the rotation direction of the driven gear is opposite to the rotation direction of the feed roller. This causes the driven gear to drive the connecting shaft on the licker-in roller to rotate in the opposite direction via another rotating shaft. This makes the licker-in roller rotate in the same direction as the feed roller, while the cylinder rotates in the opposite direction to the feed roller. Therefore, the cylinder rotates in the opposite direction to the licker-in roller. Through the above two transmission methods, the direction of rotation between the rollers can be changed at will, so that the carding device can card cotton normally, ensuring the quality of carding and the autonomy of carding.

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1: Please refer to Figures 1-5 , Figure 8 and Figure 9This invention provides a technical solution: a carding device for textile cotton yarn production, comprising a machine body 1, a collecting roller 2 rotatably connected to one end of the machine body 1, and a feed inlet 3 opened at the other end of the machine body 1. A feed roller 4, a licker-in roller 5, a breast cylinder 6, a transfer roller 8, a doffer 9, a main cylinder 10, and a discharge roller 11 are rotatably connected to the inner wall of the machine body 1. A secondary cover plate 7 partially surrounds the breast cylinder 6, and a main cover plate 12 partially surrounds the main cylinder 10. A motor 13 is installed on the side wall of the machine body 1. One end of a first drive shaft 14 is fixedly connected to the output end of the motor 13. The other end of the first drive shaft 14 is fixedly connected to the end face of the feed roller 4. A drive sprocket 15 is fixedly sleeved on the outer surface of the first drive shaft 14, and one end of a first chain 16 is meshed with the outer surface of the drive sprocket 15. The other end of the chain 16 is engaged with a first driven sprocket 17. One end of a rotating shaft 18 is fixedly sleeved on the central axis of the first driven sprocket 17. The other end of the rotating shaft 18 has a sliding cavity 19. A guide block 20 is slidably sleeved in the sliding cavity 19. A collar 21 is fixedly sleeved on the outer surface of the guide block 20. A groove 22 is opened on the outer surface of the collar 21. A toothed block 23 is slidably sleeved in the groove 22. A return spring 24 is fixedly connected between the end face of the toothed block 23 and the groove 22. A connecting shaft 25 is fixedly connected on the central axis of the cylinder 6. An annular cavity 26 is opened in the connecting shaft 25. A fixed toothed ring 27 is fixedly sleeved on the inner surface of the annular cavity 26. A worm gear 28 is fixedly sleeved on the outer surface of the connecting shaft 25. A lead screw 29 is engaged and sleeved on the side wall of the machine body 1. The end face of the lead screw 29 is rotatably connected to the end face of the guide block 20.

[0021] Please see Figure 5 and Figure 8 Multiple connecting shafts 25 and rotating shafts 18 are provided, with multiple connecting shafts 25 corresponding to multiple rotating shafts 18 one by one, and multiple connecting shafts 25 corresponding to the piercing roller 5, chest cylinder 6, secondary cover plate 7, transfer roller 8, doffer 9, main cylinder 10 and discharge roller 11 one by one. The first driven sprocket 17 and the first transmission sprocket 30 are arranged side by side.

[0022] Please see Figure 8 The end of the rotating shaft 18 is slidably sleeved with the annular cavity 26. The inner diameter of the annular cavity 26 decreases step by step. Multiple fixed toothed rings 27 are provided, and the inner diameter of the multiple fixed toothed rings 27 decreases step by step. The toothed block 23 is meshed with the fixed toothed ring 27.

[0023] Please see Figure 8 and Figure 9 The lead screw 29 is slidably sleeved with the rotating shaft 18, and the collar 21 is slidably sleeved with the rotating shaft 18. Multiple tooth blocks 23 are provided, and the multiple tooth blocks 23 are evenly distributed about the central axis of the collar 21.

[0024] Specifically, during the carding process, the rotation of the first drive shaft 14 drives the drive sprocket 15 to rotate, causing the first chain 16 on the drive sprocket 15 to rotate, which in turn drives the first driven sprocket 17 to rotate. This causes the shaft 18 on the first driven sprocket 17 to rotate via the sliding cavity 19 and the guide block 20, which in turn drives the collar 21 to rotate. This causes the toothed block 23 on the collar 21 to rotate, which in turn drives the connecting shaft 25 on the fixed toothed ring 27 to rotate. This, in turn, causes the connecting shaft 25 to rotate, which in turn drives the cylinder 6 to rotate. If it is necessary to adjust the speed ratio between the cylinder 6 and the feed roller 4, The lead screw 29 outside the rotating body 1 rotates and enters the body 1. At this time, the lead screw 29 pushes the guide block 20 to translate along the slide cavity 19, causing the collar 21 on the guide block 20 to drive the tooth block 23 to translate. This causes the tooth block 23 to be squeezed by the side wall of the ring cavity 26. The inner diameter of the ring cavity 26 decreases step by step, causing the tooth block 23 to gradually shrink into the groove 22 under pressure and compress the return spring 24. At this time, the effective radius of rotation of the tooth block 23 decreases, and the effective radius of the fixed tooth ring 27 meshing with the tooth block 23 increases. According to the formula of linear velocity and radius... It can be seen that when the angular velocity of the rotating shaft 18, i.e. the angular velocity of the feed roller 4, is constant, the smaller the radius, the smaller the linear velocity. Therefore, the linear velocity of the contracted tooth block 23 decreases, which in turn decreases the linear velocity of the fixed tooth ring 27 driven by the tooth block 23. According to the above formula, if the linear velocity decreases and the radius increases, the angular velocity will inevitably decrease. Therefore, the rotational speed of the cylinder 6 driven by the connecting shaft 25 decreases, and vice versa. Thus, the rotational speed ratio between each roller can be freely adjusted according to the requirements, and the difference in rotational speed between each roller can be fully considered. In this way, the requirements of multiple roller rotational speeds can be met by the same motor 13, without the need for multiple motors 13 and electrical control. This not only reduces the cost input and the risk of equipment damage, but also simplifies the electrical control and wiring.

[0025] Example 2: Please refer to Figure 2 , Figures 4-7 This invention provides a technical solution: a carding device for textile cotton yarn production, wherein a fan housing 35 is fixedly connected to the side wall of the machine body 1, a rotating shaft 36 is rotatably sleeved on the central axis of the fan housing 35, blades 37 are fixedly connected to both ends of the rotating shaft 36, and a third driven sprocket 38 is fixedly sleeved on the outer surface of the rotating shaft 36. One end of a third chain 39 is meshed and sleeved on the outer surface of the third driven sprocket 38, and a second transmission sprocket 40 is meshed and sleeved on the other end of the third chain 39. A driven helical gear 41 is fixedly connected to the end face of the second transmission sprocket 40, and a driving helical gear 42 is meshed and connected to the outer surface of the driven helical gear 41. One end of a second transmission shaft 43 is fixedly connected to the central axis of the driving helical gear 42, and a worm gear 44 is fixedly connected to the other end of the second transmission shaft 43. One end of a conduit 45 is fixedly connected to the output end of the fan housing 35, and the other end of the conduit 45 communicates with the dust removal knife and the upper part of the secondary cover plate 7.

[0026] Please see Figure 5 The worm gear 44 is meshed with the worm 28, the third chain 39 is slidably sleeved with the fan housing 35, and the third chain 39 is slidably sleeved with the side wall of the body 1.

[0027] Please see Figure 5 The second transmission sprocket 40 and the second transmission shaft 43 are both rotatably connected to the side wall of the machine body 1, and the blades 37 at both ends of the rotating shaft 36 are symmetrically arranged about the bisecting plane of the fan casing 35.

[0028] Specifically, during the process of improving the cotton yarn feeding efficiency, the motor 13 drives the feed roller 4 to increase its speed through the first transmission shaft 14. At the same time, the first transmission shaft 14 drives the connecting shaft 25 to increase its speed through the above process, thereby increasing the speed of the worm 28 on the connecting shaft 25. This causes the worm 28 to drive the worm wheel 44 to increase its speed, which in turn causes the worm wheel 44 to accelerate the rotation of the driving helical gear 42 through the second transmission shaft 43. This causes the driven helical gear 41 on the driving helical gear 42 to accelerate the rotation of the second transmission sprocket 40. The second transmission sprocket 40 then accelerates the rotation of the third driven sprocket 38 and the rotating shaft 36 through the third chain 39. This causes the blades 37 on the rotating shaft 36 to rotate faster, thereby increasing the suction efficiency of the blades 37. The airflow is then transmitted to the machine body 1 through the duct 45, achieving the purpose of increasing suction efficiency and maintaining the stability and efficiency of the airflow inside the device. This ensures efficient and stable carding, guaranteeing the fiber combing and impurity removal effects.

[0029] Example 3: Please refer to Figure 4 and Figure 5 The present invention provides a technical solution: a carding device for producing cotton yarn, wherein a first transmission sprocket 30 is fixedly sleeved at the end of a rotating shaft 18, one end of a second chain 31 is meshed and sleeved on the outer surface of the first transmission sprocket 30, and a second driven sprocket 32 ​​is meshed and sleeved on the other end of the second chain 31. A driving gear 33 is fixedly connected to the end face of the second driven sprocket 32, and a driven gear 34 is meshed and connected to the outer surface of the driving gear 33.

[0030] Please see Figure 3 and Figure 4 The second driven sprocket 32 ​​and the driving gear 33 are both rotatably sleeved with the side wall of the machine body 1, and the driven gear 34 is fixedly sleeved with the rotating shaft 18 on the licker roller 5.

[0031] Specifically, during the process where the rotation direction of the cylinder 6 and the feed roller 4 is opposite, when it is necessary for the cylinder 6 and the licker-in roller 5 to rotate in opposite directions, and the licker-in roller 5 and the feed roller 4 to rotate in the same direction, the rotating shaft 18 drives the second driven sprocket 32 ​​to rotate through the first transmission sprocket 30 and the second chain 31, so that the driving gear 33 on the second driven sprocket 32 ​​drives the driven gear 34 to rotate. At this time, the rotation direction of the driven gear 34 is opposite to the rotation direction of the feed roller 4, so that the driven gear 34 drives the connecting shaft 25 on the licker-in roller 5 to reverse through another rotating shaft 18, so that the licker-in roller 5 and the feed roller 4 rotate in the same direction, while the cylinder 6 and the feed roller 4 rotate in opposite directions. Therefore, the cylinder 6 and the licker-in roller 5 rotate in opposite directions. Through the above two transmission methods, the direction of rotation between each roller can be changed at will, so that the carding device can card cotton normally, ensuring the carding quality and the autonomy of carding.

[0032] The working principle and usage process of this invention are as follows: When carding is required, the cotton roll is put into the feed inlet 3 and the motor 13 is started. The motor 13 drives the feed roller 4 to rotate through the first transmission shaft 14, so that the feed roller 4 cooperates with the feed inlet 3 to guide the cotton roll, so that the cotton roll comes into contact with the licker-in roller 5. The licker-in roller 5 holds and performs preliminary carding. The fibers after preliminary carding are transferred to the breast cylinder 6. The breast cylinder 6 cooperates with the secondary cover plate 7 to perform further carding, gradually decomposing into smaller fiber bundles. The transfer roller 8 then transfers the smaller fiber bundles to the doffer 9. The doffer 9 condenses the fibers into a fiber layer. Finally, the main cylinder 10 and the main cover plate 12 perform full carding. The fibers after full carding are transferred from the main cylinder 10 to the discharge roller 11. The discharge roller 11 condenses the fibers into a fiber layer again and transfers them to the collection roller 2 to complete the carding operation. During the carding process described above, the rotation of the first drive shaft 14 drives the drive sprocket 15 to rotate, causing the first chain 16 on the drive sprocket 15 to rotate, which in turn drives the first driven sprocket 17 to rotate. This causes the shaft 18 on the first driven sprocket 17 to rotate via the sliding cavity 19 and the guide block 20, which in turn drives the collar 21 to rotate. This causes the toothed block 23 on the collar 21 to rotate, which in turn drives the connecting shaft 25 on the fixed toothed ring 27 to rotate. This, in turn, causes the connecting shaft 25 to rotate, which in turn drives the cylinder 6 to rotate. If it is necessary to adjust the speed ratio between the cylinder 6 and the feed roller 4 at this point... The lead screw 29 outside the rotating body 1 rotates and enters the body 1. At this time, the lead screw 29 pushes the guide block 20 to translate along the slide cavity 19, causing the collar 21 on the guide block 20 to drive the tooth block 23 to translate. This causes the tooth block 23 to be squeezed by the side wall of the ring cavity 26. The inner diameter of the ring cavity 26 decreases step by step, causing the tooth block 23 to gradually shrink into the groove 22 under pressure and compress the return spring 24. At this time, the effective radius of rotation of the tooth block 23 decreases, and the effective radius of the fixed tooth ring 27 meshing with the tooth block 23 increases. According to the formula of linear velocity and radius... It can be seen that when the angular velocity of the rotating shaft 18, i.e. the angular velocity of the feed roller 4, is constant, the smaller the radius, the smaller the linear velocity. Therefore, the linear velocity of the contracted tooth block 23 decreases, which in turn decreases the linear velocity of the fixed tooth ring 27 driven by the tooth block 23. According to the above formula, if the linear velocity decreases and the radius increases, the angular velocity will inevitably decrease. Therefore, the rotational speed of the cylinder 6 driven by the connecting shaft 25 decreases, and vice versa. Thus, the rotational speed ratio between each roller can be freely adjusted according to the requirements, and the difference in rotational speed between each roller can be fully considered. In this way, the requirements of multiple roller rotational speeds can be met by the same motor 13 without the need for multiple motors 13 and electrical control. This not only reduces the cost input and the risk of equipment damage, but also simplifies the electrical control and wiring. In the above process, the rotation direction of the cylinder 6 and the feed roller 4 is opposite. When the cylinder 6 and the licker-in roller 5 need to rotate in opposite directions and the licker-in roller 5 and the feed roller 4 need to rotate in the same direction, the rotating shaft 18 drives the second driven sprocket 32 ​​to rotate through the first transmission sprocket 30 and the second chain 31, so that the driving gear 33 on the second driven sprocket 32 ​​drives the driven gear 34 to rotate. At this time, the rotation direction of the driven gear 34 is opposite to the rotation direction of the feed roller 4, so that the driven gear 34 drives the connecting shaft 25 on the licker-in roller 5 to reverse through another rotating shaft 18, so that the licker-in roller 5 and the feed roller 4 rotate in the same direction, while the cylinder 6 and the feed roller 4 rotate in opposite directions. Therefore, the cylinder 6 and the licker-in roller 5 rotate in opposite directions. Through the above two transmission methods, the direction of rotation between each roller can be changed at will, so that the carding device can card cotton normally, ensuring the carding quality and the autonomy of carding. When the cotton yarn feeding efficiency is increased, the motor 13 drives the feed roller 4 to increase its speed through the first drive shaft 14. At the same time, the first drive shaft 14 drives the connecting shaft 25 to increase its speed through the above process, thereby increasing the speed of the worm 28 on the connecting shaft 25. The worm 28 drives the worm wheel 44 to increase its speed, which in turn causes the worm wheel 44 to accelerate the rotation of the driving helical gear 42 through the second drive shaft 43. This causes the driven helical gear 41 on the driving helical gear 42 to accelerate the rotation of the second drive sprocket 40. The second drive sprocket 40 then accelerates the rotation of the third driven sprocket 38 and the rotating shaft 36 through the third chain 39. This causes the blades 37 on the rotating shaft 36 to rotate faster, thereby increasing the suction efficiency of the blades 37. The airflow is then transmitted to the machine body 1 through the duct 45, achieving the purpose of increasing the suction efficiency and maintaining the stability and efficiency of the airflow inside the device. This ensures that the carding process is efficient and stable, guaranteeing the fiber combing and impurity removal effects, and completing the operation.
