Description

Technical Field

[0001] This invention relates to the field of carding machine technology, and more specifically, to a continuous high-efficiency carding machine used in the production of polyester-cotton yarn. Background Technology

[0002] In the production of polyester-cotton yarn, the carding process is one of the core steps determining the final yarn quality. Its main function is to open, comb, and remove impurities from the polyester-cotton blend layer from the previous process, breaking down the crimped fibers into basically straight single fibers. It removes residual fine impurities and non-spinnable short fibers, providing a uniform and clean sliver for subsequent drawing, roving, and spinning processes. This directly affects key indicators of the polyester-cotton yarn, such as evenness, nipple content, and breaking strength. Continuous high-efficiency carding machines, as core equipment for large-scale polyester-cotton yarn production, are widely used in modern textile enterprises due to their advantages of continuous feeding, efficient carding, and high degree of automation. Their working efficiency and operational stability directly determine the production efficiency and product qualification rate of polyester-cotton yarn.

[0003] As the core combing element of a continuous high-efficiency carding machine, the carding teeth directly contact the polyester-cotton fibers, undertaking the functions of fiber penetration, tearing, combing, and transfer. The tooth shape, sharpness, abrasion resistance, and arrangement precision of the carding teeth have a decisive impact on the combing effect. Because polyester-cotton fibers combine the abrasion resistance of polyester fibers with the flexibility of cotton fibers, the carding teeth are continuously subjected to friction and impact during continuous high-speed combing. After long-term operation, damage such as blunted tooth tips, tooth deformation, and even tooth breakage can easily occur. Furthermore, when producing polyester-cotton yarns of different specifications and ratios, parameters such as tooth spacing, tooth height, and tooth tip angle need to be adjusted according to fiber characteristics to adapt to different combing needs and ensure that the combing quality meets standards. Therefore, regular inspection, maintenance, and replacement of the carding teeth are essential for ensuring the stable operation of continuous high-efficiency carding machines and maintaining the quality of polyester-cotton yarn production.

[0004] Currently, in continuous high-efficiency carding machines used in polyester-cotton yarn production, the carding teeth mostly adopt an integrated fixed structure. That is, the carding teeth are fixedly connected to the tooth holder, needle plate, or roller body and cannot be disassembled individually. When some carding teeth are worn, deformed, or broken, it is impossible to replace individual damaged carding teeth. Instead, the entire tooth holder, needle plate, or roller must be replaced as a whole, which not only significantly increases replacement costs but also wastes a large number of parts. For example, some carding machines use an integral wrapped structure for the cylinder and licker-in carding cloth. Even if only a few broken teeth or excessive wear occur in a local area, the old carding cloth must be completely removed and new carding cloth must be rewound, which is cumbersome and time-consuming. Summary of the Invention

[0005] To overcome the above-mentioned defects, the present invention provides a continuous high-efficiency carding machine for polyester-cotton yarn production, which solves the technical problem in the prior art that it is inconvenient to replace damaged carding teeth.

[0006] According to one aspect, at least one embodiment of the present invention provides a continuous high-efficiency carding machine for polyester-cotton yarn production, comprising a carding housing with a feed inlet, a conveyor, a pressing mechanism, support columns, a first motor, a carding mechanism, and a blower mechanism. The conveyor is installed inside the carding housing and configured to extend through the feed inlet to the outside of the carding housing to achieve continuous conveying of polyester-cotton yarn. The pressing mechanism is disposed inside the carding housing and is used to press the polyester-cotton yarn onto the conveyor. Two support columns are rotatably disposed inside the carding housing, with one end of each support column extending through the side wall of the carding housing. The first motor is mounted on the side wall of the carding housing on one side of the support column, and the output end of the first motor is fixedly connected to a nearby support column. The carding mechanism is disposed on the support column and configured to contact the polyester-cotton yarn on the conveyor to open and separate the yarn. The blower mechanism is disposed on the carding housing and configured to blow air onto the polyester-cotton yarn on the conveyor, cooperating with the pressing mechanism to press the yarn.

[0007] Preferably, the blower mechanism includes a mounting port and a blower. The mounting port is located on the top side wall of the carding housing. The carding housing is fixed with a mounting plate by bolts on the top side of the mounting port. The blower is mounted on the mounting plate, and the output end of the blower extends through the mounting plate into the carding housing, enabling it to blow airflow into the carding housing.

[0008] Furthermore, the carding mechanism includes a main arc plate, a secondary arc plate, carding teeth, and an installation mechanism. The main arc plate and the secondary arc plate are disposed on both sides of the support column. The bottom end of the main arc plate is hinged to the bottom end of the secondary arc plate. The main arc plate and the secondary arc plate are fitted onto the support column. Multiple arc-shaped carding teeth are fixedly disposed on the outer walls of both the main arc plate and the secondary arc plate. The installation mechanism is disposed between the support column and the main arc plate and the secondary arc plate, respectively, for mounting the main arc plate and the secondary arc plate onto the support column.

[0009] Furthermore, the installation mechanism includes an installation groove, an installation seat, a plate positioning groove, a column positioning groove, and a synchronous rotation mechanism. The side wall of the support column has multiple installation grooves. The inner wall of the secondary arc plate is fixedly provided with multiple installation seats, the shapes of which are adapted to the installation grooves. The inner walls of both the main arc plate and the secondary arc plate have plate positioning grooves. The side wall of the support column, located on one side of the plate positioning groove, has a column positioning groove. A positioning gear is rotatably installed within the column positioning groove. A positioning seat is fixedly installed on the side wall of the positioning gear, its shape adapted to the column positioning groove, and configured to extend into the plate positioning groove as the positioning gear rotates, thus achieving fixed positioning of the main arc plate, the secondary arc plate, and the support column. The synchronous rotation mechanism is located within the support column and is used to drive the positioning gears on both sides of the support column to rotate synchronously.

[0010] Furthermore, the synchronous rotation mechanism includes a movable seat, a threaded rod, and a multi-stage synchronous transmission mechanism. A first cavity is formed in the support column at the bottom side of the column positioning groove. The movable seat is slidably disposed in the first cavity. A first rack is fixedly disposed on the side wall of the movable seat. The first rack meshes with the positioning gear. The threaded rod is rotatably disposed in the first cavity. The threaded rod passes through the movable seat through a threaded engagement. The multi-stage synchronous transmission mechanism is disposed in the support column and is configured to drive multiple threaded rods to rotate synchronously around their own axes, thereby realizing the synchronous sliding of multiple movable seats.

[0011] Based on the above scheme, the multi-stage synchronous transmission mechanism includes a second cavity, a transmission bevel gear, and a drive mechanism. The second cavity is located between two opposing first cavities within the support column. A connecting rod bevel gear is rotatably mounted on the inner wall of the second cavity near the threaded rod. The connecting rod bevel gear is fixedly connected to the adjacent threaded rod. The transmission bevel gear is rotatably mounted on the inner wall of the second cavity and meshes with the adjacent connecting rod bevel gear. The drive mechanism is mounted on the support column and is used to drive multiple transmission bevel gears to rotate. The drive mechanism includes a handwheel and a drive rod. The handwheel is rotatably mounted at one end of the support column, and the drive rod is fixedly mounted on the handwheel. The drive rod extends into the support column and is fixedly connected to the transmission bevel gear.

[0012] Based on the above solution, a cleaning mechanism is also included. The cleaning mechanism is disposed inside the carding housing and is used to clean the cotton fibers wrapped around the carding teeth. The cleaning mechanism includes a cleaning roller, a cleaning seat, and a second motor. The cleaning roller is rotatably disposed inside the carding housing and located between the two support columns. The cleaning seats are evenly distributed on the side wall of the cleaning roller. The cleaning seats have cleaning grooves that are adapted to the shape of the carding teeth. The second motor is mounted on the side wall of the carding housing, and the output end of the second motor is fixedly connected to the cleaning roller. A cleaning cavity is formed inside the cleaning roller. An air outlet is formed between the bottom of the cleaning groove and the cleaning cavity. An air supply pipe is provided through the side wall of the carding housing. One end of the air supply pipe extends through the side wall of the cleaning roller and into the cleaning cavity. The cleaning cavity can accommodate high-pressure airflow. The air outlet is configured to export the high-pressure airflow in the cleaning cavity and blow off the cotton fibers scraped into the cleaning groove.

[0013] Based on the above scheme, the pressing mechanism includes a support frame and a support spring. The support frame is slidably arranged at both ends inside the carding housing. A pressing roller is rotatably arranged inside the support frame. The support spring is fixedly arranged between the top side wall of the support frame and the inner top wall of the carding housing. The pressing roller is configured to press against the surface of the polyester-cotton yarn under the elastic force of the support spring, thereby achieving flexible pressing of the polyester-cotton yarn.

[0014] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, the main arc plate and the secondary arc plate can be installed on the surface of the support column by rotating the handwheel, and different main arc plates and secondary arc plates can be disassembled by rotating the handwheel in the opposite direction, which facilitates the targeted replacement of the carding teeth. At the same time, the rotation of the support column can drive the main arc plate, the secondary arc plate and the carding teeth to move around the support column, which facilitates the carding process of polyester-cotton yarn. 2. In this invention, by setting up a pressing mechanism and a blower mechanism, after the polyester-cotton yarn is placed on the conveyor, it can be conveyed by the operation of the conveyor. At the same time, under the elastic force of the support spring, the pressing roller can "press" the polyester-cotton yarn onto the conveyor. Meanwhile, the blower can blow air onto the surface of the polyester-cotton yarn, thereby further "pressing" the polyester-cotton yarn onto the surface of the conveyor for conveying, thus avoiding the polyester-cotton yarn from scattering and affecting the carding effect. 3. In this invention, the cleaning mechanism allows the cleaning roller to rotate, causing the cleaning seat to move around the cleaning roller. Simultaneously, during the movement of the cleaning seat, the movement of the carding teeth causes the carding teeth to pass through the cleaning grooves on the cleaning seat. This allows the cotton fibers to be pushed out from the surface of the carding teeth through the sidewalls of the cleaning grooves. At the same time, the cotton fibers can be removed from the cleaning grooves by the air blowing from the air outlet. In addition, the air blowing from the blower "presses" the cotton fibers onto the conveyor, thereby preventing the cotton fibers from getting tangled on the carding teeth and the cleaning seat and affecting the carding effect.

[0023] like Figures 1-10 The diagram illustrates a continuous high-efficiency carding machine for polyester-cotton yarn production according to an embodiment of the present invention. It includes a carding housing 1 with a feed inlet 2, a conveyor 3, a pressing mechanism, a support column 4, a first motor 5, a carding mechanism, and a blower mechanism. The conveyor 3 is installed inside the carding housing 1 and is configured to extend through the feed inlet 2 to the outside of the carding housing 1, enabling continuous conveying of the polyester-cotton yarn. The pressing mechanism is located inside the carding housing 1 and is used to press the polyester-cotton yarn onto the conveyor 3. The carding housing 1 has two rotating support columns 4. One end of each support column 4 extends through the side wall of the carding housing 1. A first motor 5 is installed on the side wall of the carding housing 1 on one side of the support column 4. The output end of the first motor 5 is fixedly connected to the adjacent support column 4. The carding mechanism is mounted on the support column 4 and is configured to contact the polyester-cotton yarn on the conveyor 3 to open and separate the polyester-cotton yarn. The blower mechanism is mounted on the carding housing 1 and is configured to blow air onto the polyester-cotton yarn on the conveyor 3, and work with the pressing mechanism to press the polyester-cotton yarn.

[0024] Reference Figures 1-4 The blower mechanism includes an installation port and a blower 7. The installation port is located on the top side wall of the carding housing 1. The carding housing 1 is fixed with an installation plate 6 by bolts on the top side of the installation port. The blower 7 is installed on the installation plate 6. The output end of the blower 7 passes through the installation plate 6 and extends into the carding housing 1. The blower 7 can blow airflow into the carding housing 1.

[0025] The pressing mechanism includes a support frame 29 and a support spring 31. The support frame 29 is slidably installed at both the feed end and the discharge end inside the carding housing 1. The pressing roller 30 is rotatably installed inside the support frame 29. The support spring 31 is fixedly installed between the top side wall of the support frame 29 and the inner top wall of the carding housing 1. The pressing roller 30 is configured to press against the surface of the polyester-cotton yarn under the elastic force of the support spring 31, thereby achieving flexible pressing of the polyester-cotton yarn.

[0026] Specifically, after the polyester-cotton yarn is placed on the conveyor 3, it can be transported by the operation of the conveyor 3. At the same time, under the elastic force of the support spring 31, the polyester-cotton yarn can be "pressed" onto the conveyor 3 by the holding roller 30. Meanwhile, the operation of the fan 7 can blow air onto the surface of the polyester-cotton yarn, thereby further "pressing" the polyester-cotton yarn onto the surface of the conveyor 3 for transport, thus preventing the polyester-cotton yarn from scattering and affecting the carding effect.

[0027] Reference Figures 3-7 The carding mechanism includes a main arc plate 8, a secondary arc plate 9, carding teeth 10, and an installation mechanism. The main arc plate 8 and the secondary arc plate 9 are located on both sides of the support column 4. The bottom end of the main arc plate 8 is hinged to the bottom end of the secondary arc plate 9. The main arc plate 8 and the secondary arc plate 9 are fitted onto the support column 4. Multiple arc-shaped carding teeth 10 are fixedly provided on the outer walls of the main arc plate 8 and the secondary arc plate 9. The installation mechanism is located between the support column 4 and the main arc plate 8 and the secondary arc plate 9, respectively, and is used to install the main arc plate 8 and the secondary arc plate 9 onto the support column 4. Specifically, the operation of the first motor 5 can drive the support column 4 to rotate. At the same time, the rotation of the support column 4 can drive the main arc plate 8, the secondary arc plate 9, and the carding teeth 10 to move around the support column 4, thereby facilitating the carding process of the polyester-cotton yarn.

[0028] Reference Figures 7-9 The installation mechanism includes an installation groove 11, an installation base 12, a plate positioning groove 13, a column positioning groove 14, and a synchronous rotation mechanism. Multiple installation grooves 11 are provided on the side wall of the support column 4. Multiple installation bases 12 are fixedly installed on the inner wall of the secondary arc plate 9. The shapes of the installation bases 12 and installation grooves 11 are adapted to each other. Plate positioning grooves 13 are provided on the inner walls of both the main arc plate 8 and the secondary arc plate 9. A column positioning groove 14 is provided on one side of the plate positioning groove 13 on the side wall of the support column 4. A positioning gear 15 is rotatably installed in the column positioning groove 14. A positioning seat 16 is fixedly installed on the side wall of the positioning gear 15. The positioning seat 16 is adapted to the shape of the column positioning groove 14. The positioning seat 16 is configured to extend into the plate positioning groove 13 as the positioning gear 15 rotates, thus achieving fixed positioning of the main arc plate 8, the secondary arc plate 9, and the support column 4. The synchronous rotation mechanism is installed inside the support column 4 and is used to drive the positioning gears 15 on both sides of the support column 4 to rotate synchronously.

[0029] The synchronous rotation mechanism includes a movable seat 17, a threaded rod 18, and a multi-stage synchronous transmission mechanism. A first cavity is formed on the bottom side of the column positioning groove 14 inside the support column 4. The movable seat 17 is slidably arranged in the first cavity. A first rack is fixedly arranged on the side wall of the movable seat 17. The first rack meshes with the positioning gear 15. The threaded rod 18 is rotatably arranged in the first cavity. The threaded rod 18 passes through the movable seat 17 through the threaded engagement. The multi-stage synchronous transmission mechanism is arranged in the support column 4 and is configured to drive multiple threaded rods 18 to rotate synchronously around their own axes, so as to realize the synchronous sliding of multiple movable seats 17.

[0030] The multi-stage synchronous transmission mechanism includes a second cavity, a transmission bevel gear 20, and a drive mechanism. A second cavity is provided inside the support column 4 between two opposing first cavities. A connecting rod bevel gear 19 is rotatably mounted on the inner wall of the second cavity near the threaded rod 18. The connecting rod bevel gear 19 is fixedly connected to the nearby threaded rod 18. The transmission bevel gear 20 is rotatably mounted on the inner wall of the second cavity and meshes with the nearby connecting rod bevel gear 19. The drive mechanism is mounted on the support column 4 and is used to drive multiple transmission bevel gears 20 to rotate. The drive mechanism includes a handwheel 21 and a drive rod 22. The handwheel 21 is rotatably mounted on one end of the support column 4, and the drive rod 22 is fixedly mounted on the handwheel 21. The drive rod 22 extends into the support column 4 and is fixedly connected to the transmission bevel gear 20.

[0031] Specifically, after attaching the secondary arc plate 9 to the surface of the support column 4 and inserting the mounting base 12 into the mounting groove 11, the main arc plate 8 can be rotated to attach it to the support column 4. Then, the operator turns the handwheel 21. The rotation of the handwheel 21 can drive the drive rod 22 and the transmission bevel gear 20 to rotate. At the same time, through the meshing of the transmission bevel gear 20 and the connecting rod bevel gear 19, the connecting rod bevel gear 19 and the threaded rod 18 are driven to rotate. The rotation of the threaded rod 18 can drive the moving base 17 and the first rack to move. Moreover, during the movement of the first rack, through the meshing of the first rack and the positioning gear 15, the positioning gear 15 can be driven to rotate. The rotation of the positioning gear 15 can drive the positioning seat 16 to move around the positioning gear 15, so that the positioning seat 16 can extend into the plate positioning groove 13 and abut against the side wall of the plate positioning groove 13. Thus, the main arc plate 8 and the secondary arc plate 9 can be spliced ​​and positioned by the cooperation of the positioning seat 16 and the plate positioning groove 13. At the same time, the positioning between the secondary arc plate 9 and the support column 4 can be achieved by the cooperation of the mounting seat 12 and the mounting groove 11, which facilitates the installation between the main arc plate 8 and the secondary arc plate 9 and the support column 4. The main arc plate 8 and the secondary arc plate 9 can be disassembled by rotating the handwheel 21 in the opposite direction, which facilitates the replacement of the main arc plate 8 and the secondary arc plate 9.

[0032] Reference Figure 3 , Figure 4 as well as Figure 10It also includes a cleaning mechanism, which is located inside the carding housing 1 and is used to clean the cotton fibers wrapped around the carding teeth 10. The cleaning mechanism includes a cleaning roller 23, a cleaning seat 24, and a second motor 26. The cleaning roller 23 is rotatably mounted inside the carding housing 1 and located between two support columns 4. The side walls of the cleaning roller 23 are evenly distributed with cleaning seats 24, and the cleaning seats 24 are provided with cleaning grooves 25. The cleaning grooves 25 are adapted to the shape of the carding teeth 10. The second motor 26 is installed in the carding housing 1. On the side wall, the output end of the second motor 26 is fixedly connected to the cleaning roller 23. The cleaning roller 23 has a cleaning cavity inside. An air outlet 27 is provided between the bottom of the cleaning channel 25 and the cleaning cavity. An air supply pipe 28 is provided through the side wall of the carding shell 1. One end of the air supply pipe 28 extends through the side wall of the cleaning roller 23 into the cleaning cavity. The cleaning cavity can accommodate high-pressure airflow. The air outlet 27 is configured to export the high-pressure airflow in the cleaning cavity and blow off the cotton fibers scraped into the cleaning channel 25.

[0033] Specifically, the operation of the second motor 26 can drive the cleaning roller 23 to rotate. The rotation of the cleaning roller 23 can drive the cleaning seat 24 to move around the cleaning roller 23. At the same time, during the movement of the cleaning seat 24, in conjunction with the movement of the carding teeth 10, the carding teeth 10 pass through the cleaning groove 25 on the cleaning seat 24. Thus, the cotton fibers can be pushed out from the surface of the carding teeth 10 through the side wall of the cleaning groove 25. At the same time, the cotton fibers can be removed from the cleaning groove 25 by the air blowing through the air outlet 27. Meanwhile, in conjunction with the air blowing of the fan 7, the cotton fibers are "pressed" onto the conveyor 3, thereby preventing the cotton fibers from getting tangled on the carding teeth 10 and the cleaning seat 24 and affecting the carding effect.

[0034] In this embodiment, during use, the operator opens the mounting plate 6. After attaching the secondary arc plate 9 to the surface of the support column 4 and inserting the mounting base 12 into the mounting groove 11, the operator can rotate the main arc plate 8 to attach it to the support column 4. Then, the operator rotates the handwheel 21. The rotation of the handwheel 21 drives the drive rod 22 and the transmission bevel gear 20 to rotate. Simultaneously, the meshing of the transmission bevel gear 20 with the connecting rod bevel gear 19 drives the connecting rod bevel gear 19 and the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the moving seat 17 and the first rack to move. Furthermore, the first rack... During the movement, the positioning gear 15 can be rotated by the meshing of the first rack and the positioning gear 15. The rotation of the positioning gear 15 can drive the positioning seat 16 to move around the positioning gear 15, so that the positioning seat 16 can extend into the plate positioning groove 13 and abut against the side wall of the plate positioning groove 13. Thus, the main arc plate 8 and the secondary arc plate 9 can be spliced ​​and positioned by the cooperation of the positioning seat 16 and the plate positioning groove 13. At the same time, the positioning between the secondary arc plate 9 and the support column 4 can be achieved by the cooperation of the mounting seat 12 and the mounting groove 11, which facilitates the installation of the main arc plate 8 and the secondary arc plate 9 and the support column 4.

[0035] Afterwards, the operator fixes the mounting plate 6 to the top side wall of the carding housing 1 with bolts. Then, after the operator places the polyester-cotton yarn on the conveyor 3, the polyester-cotton yarn can be conveyed by the operation of the conveyor 3. At the same time, under the elastic force of the support spring 31, the polyester-cotton yarn can be "pressed" onto the conveyor 3 by the holding roller 30. At the same time, the operation of the fan 7 can blow air onto the surface of the polyester-cotton yarn, thereby further "pressing" the polyester-cotton yarn onto the surface of the conveyor 3 for conveying, thus avoiding the polyester-cotton yarn from flying away and affecting the carding effect.

[0036] The operator then controls the first motor 5 to operate, which drives the support column 4 to rotate. The rotation of the support column 4 causes the main arc plate 8, the secondary arc plate 9, and the carding teeth 10 to move around the support column 4, thus facilitating the carding of the polyester-cotton yarn. During the carding process, the operator controls the second motor 26 to operate, which drives the cleaning roller 23 to rotate. The rotation of the cleaning roller 23 causes the cleaning seat 24 to move around the cleaning roller 23. At the same time, as the cleaning seat 24 moves, the movement of the carding teeth 10, in conjunction with the movement of the carding teeth 10, causes the carding teeth 10 to pass through the cleaning groove 25 on the cleaning seat 24. This allows the cotton fibers to be pushed out of the surface of the carding teeth 10 through the side wall of the cleaning groove 25. Simultaneously, the air blower 27 blows the cotton fibers out of the cleaning groove 25. At the same time, the air blower 7 "presses" the cotton fibers onto the conveyor 3, thus preventing the cotton fibers from getting tangled on the carding teeth 10 and the cleaning seat 24 and affecting the carding effect.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
