Description

Technical Field

[0001] This invention relates to the field of cotton and linen fiber production technology, specifically to a cotton and linen fiber carding and winding machine. Background Technology

[0002] A carding machine is a spinning machine that sorts pre-processed spinning raw materials into single fibers, forms a web of fibers, and then assembles them into fiber slivers. Due to the different types of fibers and process requirements, carding machines also have various structures, such as cotton carding machines, wool carding machines, and linen carding machines.

[0003] In traditional technology, carding machines are usually horizontal structures. Cotton and linen fibers move laterally within the carding machine, which can easily cause friction with conveyor belts and other components, leading to fires due to static electricity. Summary of the Invention

[0004] The purpose of this invention is to provide a cotton and linen fiber carding and winding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cotton and linen fiber carding and winding machine, comprising a machine casing, an upper cotton box being provided in the upper half of the machine casing, and a cotton leveling swing device being connected to the top of the upper cotton box, and a dust extraction fan being connected to the side end of the pipe of the cotton leveling swing device; four feeding rollers being provided in the upper part of the upper cotton box, two cotton-pulling rollers being provided on one side of the lower end of the upper cotton box, and a cylinder roller being provided on the other side of the lower end of the upper cotton box; a lower cotton box being provided in the lower half of the machine casing, and a photoelectric sensor for detecting the remaining material being installed in the lower cotton box; a perforated vibrating plate being provided on the side wall of the lower cotton box, and an output curtain being connected to the bottom of the lower cotton box.

[0006] Furthermore, the feed rollers are divided into two groups, A and B, which are adjacent to each other. The surface of the feed rollers in group A is covered with strip-shaped teeth, while the surface of the feed rollers in group B is covered with needle-shaped teeth. The feed rollers in group A rotate at a slower speed than those in group B. The feed rollers at the left end of both groups A and B rotate clockwise, while the feed rollers at the right end of both groups A and B rotate counterclockwise. The cotton-pulling rollers at both locations rotate counterclockwise, while the cylinder roller rotates clockwise.

[0007] Furthermore, a cylinder motor is bolted to the outer wall of the housing, and a controller is fixed to the housing above the cylinder motor. A junction box is connected to the side end of the cylinder motor, and a Hall current sensor is sleeved on the cable segment between the junction box and the output end of the motor driver. A drive shaft is fixedly connected to the rotating end of the cylinder motor, and the end of the drive shaft is connected to the cylinder roller for rotational transmission.

[0008] Furthermore, a clutch linkage assembly is provided on the drive shaft. The clutch linkage assembly includes a pulley rotatably mounted on the inner wall of the housing. The pulley is rotatably engaged with a fixed bushing penetrating the housing via a ball bearing. An electromagnetic coil is embedded in the inner recess of the pulley. The electromagnetic coil is fixed to the inner wall of the housing and is electrically connected to the controller via a cable passing through the outlet hole on the housing.

[0009] Furthermore, the clutch linkage assembly also includes an armature disposed on the outside of the pulley. The armature can be attracted by an energized electromagnetic coil and fit tightly against the pulley. Two spring pieces are connected to the outside of the armature. The end of the spring piece opposite to the armature is fixed to the collar, and the collar is coaxially fixed to the middle of the drive shaft.

[0010] Furthermore, a reciprocating drive assembly is provided on the side end of the drive shaft. The reciprocating drive assembly includes a bearing bracket fixed to the inner wall of the housing. Guide rods are fixedly connected to both ends of the bearing bracket, and a reciprocating lead screw is rotatably installed in the middle of the bearing bracket. The surface of the reciprocating lead screw is machined with two helical grooves with the same pitch and opposite directions, and the two ends of the reciprocating lead screw are connected by a smooth transition curve to form a closed loop.

[0011] Furthermore, the reciprocating drive assembly also includes a driven wheel coaxially connected to the end of the reciprocating lead screw. The driven wheel is connected to the pulley via a transmission belt, and a slider is slidably mounted on the outside of the reciprocating lead screw along the axial direction. The through holes on both sides of the slider are slidably engaged with the corresponding guide rods.

[0012] Furthermore, the reciprocating drive assembly also includes connecting rods fixedly connected to both sides of the slider end. The connecting rods are limited by a notch provided at the end of the bearing bracket, and a connecting ring is fixedly connected to the end of the connecting rod.

[0013] Furthermore, the end of the connecting rod is connected to a flower cleaning assembly, which includes a rod clamped in the connecting rings at both ends. The rod has a negative pressure pipeline embedded inside, and a rotating pin is fixedly installed at the top of the rod.

[0014] Furthermore, the flower cleaning assembly also includes a cleaning hook that is rotatably connected to a rotating pin via a pin shaft. The cleaning surface of the cleaning hook is provided with a polyurethane cutting edge, and the hardness of the polyurethane cutting edge is lower than that of the metal needle teeth on the cylinder roller. A connecting pin is connected to the side end of the cleaning hook, and the connecting pin is connected to the telescopic end of the adjusting cylinder via a fisheye connector. The root of the adjusting cylinder is rotatably engaged with the pin body on the outer wall of the rod via a pin shaft.

[0015] This invention provides a cotton and linen fiber carding and winding machine, which has the following beneficial effects; 1. The carding machine of this application adopts a vertical arrangement. By changing the movement direction of cotton and linen fibers from horizontal to vertical, the relative movement direction between the cylinder roller and the fixed cover plate needle teeth forms a larger angle with the fiber arrangement direction. This increases the piercing ability of the needle teeth on the fiber bundle, which is conducive to penetrating the fiber layer to achieve full carding. It enhances the carding strength and improves the processing efficiency. It also makes it less likely for cotton and linen fibers to rub against the conveyor belt, thereby avoiding fires caused by static electricity.

[0016] 2. This application monitors the changes in current parameters caused by increased resistance when the cylinder roller is wrapped with fibers, and uses the kinetic energy of the drive shaft to drive the reciprocating drive assembly to run and execute the cleaning procedure through friction transmission. This allows for proactive intervention when fibers wrap around the cylinder roller, preventing fiber accumulation from reducing combing efficiency and ensuring combing effect.

[0017] 3. During use, the rod moves axially back and forth at the side end of the cylinder roller under the transmission action of the reciprocating screw. The inclination angle of the cleaning hook matches the curvature of the cylinder roller surface, improving the fit between the polyurethane cutting edge and the cylinder roller surface. By using polyurethane material with a hardness lower than that of the cylinder roller needle teeth for the cutting edge, the cutting edge deforms first rather than damages the needle teeth when it comes into contact with the needle teeth during the axial back and forth cleaning of the tangled fibers along the cylinder roller, reducing mechanical scraping force and thus reducing the risk of collision. Furthermore, by setting a negative pressure suction port and connecting it to a negative pressure pipeline at the rear of the cleaning hook, airflow is used to peel off the tangled fibers, avoiding secondary tangling of fibers and further improving the cleaning effect.

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Please see Figures 1 to 2 This invention provides a technical solution: a cotton and linen fiber carding and winding machine, comprising a machine housing 1, an upper cotton box 2 disposed in the upper half of the machine housing 1, a cotton leveling swing device 3 connected to the top of the upper cotton box 2, and a dust extraction fan 4 connected to the side of the pipe of the cotton leveling swing device 3; four feeding rollers 5 disposed in the upper part of the upper cotton box 2, two cotton-pulling rollers 6 disposed on one side of the lower part of the upper cotton box 2, and a cylinder roller 7 disposed on the other side of the lower part of the upper cotton box 2; and a lower cotton box 8 disposed in the lower half of the machine housing 1, wherein the lower cotton box 8 contains a device for detecting the remaining material. The photoelectric sensor has a perforated vibrating plate 9 on the side wall of the lower cotton box 8, and the bottom of the lower cotton box 8 is connected to the output curtain 10. The feed rollers 5 are divided into two groups, A and B, which are adjacent to each other. The surface of the feed rollers 5 in group A is covered with strip teeth, and the surface of the feed rollers 5 in group B is covered with needle teeth. The rotation speed of the feed rollers 5 in group A is slower than that in group B. The left feed rollers 5 in both groups A and B rotate clockwise, and the right feed rollers 5 in both groups A and B rotate counterclockwise. The two cotton-pulling rollers 6 rotate counterclockwise, and the cylinder roller 7 rotates clockwise. The specific operation is as follows: The carding machine of this application adopts a vertical arrangement, and the four feeding rollers 5 are divided into two groups, A and B, which are adjacent to each other. The surface of the feeding rollers 5 in group A is covered with strip-shaped teeth, and the surface of the feeding rollers 5 in group B is covered with needle-shaped teeth. The feeding rollers 5 in group A rotate slower than those in group B. The left feeding rollers 5 in both groups A and B rotate clockwise, and the right feeding rollers 5 in both groups A and B rotate counterclockwise. The two cotton-pulling rollers 6 rotate counterclockwise, and the cylinder roller 7 rotates clockwise. By changing the movement direction of cotton and linen fibers from horizontal to vertical, the relative movement direction between the cylinder roller 7 and the fixed cover plate needle teeth forms a larger angle with the fiber arrangement direction, which increases the piercing ability of the needle teeth on the fiber bundle, which is conducive to penetrating the fiber layer to achieve full carding, enhancing the carding strength and improving the processing efficiency. It also makes it less likely for cotton and linen fibers to rub against the conveyor belt, thereby avoiding fires caused by static electricity. Please see Figures 3 to 4 A cylinder motor 11 is bolted to the outer wall of the housing 1, and a controller 12 is fixed to the housing 1 above the cylinder motor 11. A junction box 13 is connected to the side end of the cylinder motor 11, and a Hall current sensor 14 is sleeved on the cable segment between the junction box 13 and the output end of the motor driver. A drive shaft 15 is fixedly connected to the rotating end of the cylinder motor 11, and the end of the drive shaft 15 is rotatably connected to the cylinder roller 7. A clutch linkage assembly 16 is provided on the drive shaft 15. The clutch linkage assembly 16 includes a pulley 1601 rotatably mounted on the inner wall of the housing 1. The pulley 1601 is rotatably coupled to a fixed bushing passing through the housing 1 via a ball bearing 1602. The clutch linkage assembly 16 also includes an armature 1604 located on the outside of the pulley 1601. The armature 1604 can be attracted by the energized electromagnetic coil 1603 and fit tightly against the pulley 1601. Two spring pieces 1605 are connected to the outside of the armature 1604. The end of the spring piece 1605 away from the armature 1604 is fixed to the collar 1606. The collar 1606 is coaxially fixed to the middle of the drive shaft 15. The specific operation is as follows: When cotton and linen fibers clog the spaces between the needles of the cylinder roller 7, weakening the combing ability between the cylinder needle surface and the cover plate needle surface, the rotational resistance of the cylinder roller 7 will increase due to the cotton and linen fibers clogging the needles. The additional mechanical resistance generated by the winding will increase the current load of the cylinder motor 11. In this application, a Hall current sensor 14 is connected to the cable segment between the junction box 13 and the output end of the cylinder motor 11 driver. When the winding causes the resistance to increase and the current exceeds the set threshold, the Hall current sensor 14 sends an electrical signal and triggers the linkage cleaning program of the controller 12. The built-in power supply of the controller 12 energizes the electromagnetic coil 1603 in the inner recess of the pulley 1601. At this time, the armature 16 04 is attracted by the energized electromagnetic coil 1603, overcomes the tension of the spring 1605 and fits tightly against the surface of the pulley 1601, so that the shaft collar 1606 coaxial with the drive shaft 15 is driven by friction to the pulley 1601 through the armature 1604, and then establishes power transmission with the reciprocating drive assembly 17 through the transmission belt sleeved on the outside of the pulley 1601. This application monitors the change of current parameters caused by the increase of resistance when the cylinder roller 7 is winding, and drives the reciprocating drive assembly 17 to run and execute the cleaning procedure by means of friction transmission with the kinetic energy of the drive shaft 15. It can actively intervene when the cylinder roller 7 is winding, avoid the reduction of combing efficiency due to fiber accumulation, and ensure the combing effect. Please see Figures 5 to 6 A reciprocating drive assembly 17 is provided on the side end of the drive shaft 15. The reciprocating drive assembly 17 includes a bearing bracket 1701 fixed to the inner wall of the housing 1. Guide rods 1702 are fixedly connected to both ends of the bearing bracket 1701, and a reciprocating lead screw 1703 is rotatably mounted in the middle of the bearing bracket 1701. The surface of the reciprocating lead screw 1703 is machined with two helical grooves with the same pitch and opposite directions. The two ends of the reciprocating lead screw 1703 are connected by a smooth transition curve to form a closed loop. The reciprocating drive assembly 17 also includes a coaxial connection to the reciprocating lead screw 1703. The driven wheel 1704 at the end is connected to the pulley 1601 via a transmission belt. A slider 1705 is slidably mounted on the outside of the reciprocating screw 1703 along the axial direction. The through holes on both sides of the slider 1705 are slidably engaged with the corresponding guide rods 1702. The reciprocating drive assembly 17 also includes connecting rods 1706 fixedly connected to both sides of the end of the slider 1705. The connecting rods 1706 are limited by the notches provided at the end of the bearing bracket 1701. A connecting ring 1707 is fixedly connected to the end of the connecting rods 1706. The specific operation is as follows: the driven wheel 1704 establishes power transmission with the pulley 1601 through the transmission belt, and then achieves bidirectional linear reciprocating motion through the continuous thrust of the spiral groove sidewall on the slider 1705 during the rotation of the reciprocating screw 1703. Furthermore, the front end of the slider 1705 is connected to the rod 1801 through the connecting rod 1706, so that the rod 1801 moves axially at the side end of the cylinder roller 7 under the transmission action of the reciprocating screw 1703, and returns to the inner wall of the housing 1 at the end of the stroke, so that the flower cleaning component 18 and the cylinder roller 7 are left with a gap during idle time, so as to avoid interference with the cylinder roller 7 during normal operation. Please see Figures 6 to 7 The end of the connecting rod 1706 is connected to a flower cleaning assembly 18. The flower cleaning assembly 18 includes a rod 1801 clamped in the connecting rings 1707 at both ends. A negative pressure pipeline 1802 is embedded inside the rod 1801, and a rotating pin 1803 is fixedly installed at the top of the rod 1801. The flower cleaning assembly 18 also includes a cleaning hook 1804 rotatably connected to the rotating pin 1803 via a pin shaft. The cleaning surface of the cleaning hook 1804 is provided with a polyurethane cutting edge 1805, and the hardness of the polyurethane cutting edge 1805 is lower than that of the metal needle teeth on the cylinder roller 7. A connecting pin 1806 is connected to the side end of the cleaning hook 1804, and the connecting pin 1806 is connected to the telescopic end of the adjusting cylinder 1807 via a fisheye connector. The root of the adjusting cylinder 1807 is rotatably engaged with the pin body on the outer wall of the rod 1801 via a pin shaft. The specific operation is as follows: During use, the cylinder 1807 is adjusted to drive the extension and retraction of the connecting pin 1806 at the end of the cleaning hook 1804, so that the cleaning hook 1804 rotates through the rotating pin 1803 located at the end of the rod 1801. By matching the inclination angle of the cleaning hook 1804 with the surface curvature of the cylinder roller 7, the fit between the polyurethane blade edge 1805 and the surface of the cylinder roller 7 is improved. Furthermore, by using polyurethane material with a hardness lower than that of the needle teeth of the cylinder roller 7, the polyurethane blade edge 1805 deforms first rather than damages the needle teeth when it comes into contact with them during the reciprocating cleaning of the tangled fibers along the axial direction of the cylinder roller 7, reducing the mechanical scraping force and thus reducing the risk of collision. In addition, by setting a negative pressure suction port at the rear of the cleaning hook 1804 and connecting it to the negative pressure pipeline 1802, the airflow is used to peel off the tangled fibers, avoiding secondary tangling of the fibers and further improving the cleaning effect.

[0021] In summary, when using this cotton and linen fiber carding and winding machine: First, the carding machine of this application adopts a vertical arrangement, and divides the four feeding rollers 5 into two groups, A and B, which are adjacent to each other. The surface of the feeding rollers 5 in group A is covered with strip-shaped teeth, and the surface of the feeding rollers 5 in group B is covered with needle-shaped teeth. The feeding rollers 5 in group A rotate slower than those in group B. The left feeding rollers 5 in both groups A and B rotate clockwise, and the right feeding rollers 5 in both groups A and B rotate counterclockwise. The two cotton-pulling rollers 6 rotate counterclockwise, and the cylinder roller 7 rotates clockwise. By changing the movement direction of cotton and linen fibers from horizontal to vertical, the relative movement direction between the cylinder roller 7 and the needle teeth of the fixed cover plate forms a larger angle with the fiber arrangement direction, which increases the piercing ability of the needle teeth on the fiber bundle, which is conducive to penetrating the fiber layer to achieve full carding, enhancing the carding strength and improving the processing efficiency. It also makes it less likely for cotton and linen fibers to rub against the conveyor belt, thereby avoiding fires caused by static electricity. Secondly, when cotton and linen fibers clog the spaces between the needles of the cylinder roller 7, weakening the combing ability between the cylinder needle surface and the cover plate needle surface, the rotational resistance of the cylinder roller 7 increases due to the clogged cotton and linen fibers. The additional mechanical resistance generated by the winding increases the current load of the cylinder motor 11. This application uses a Hall current sensor 14 connected to the cable segment between the junction box 13 and the output end of the cylinder motor 11 driver. When the winding causes the resistance to increase and the current exceeds the set threshold, the Hall current sensor 14 sends an electrical signal and triggers the linkage cleaning program of the controller 12. The built-in power supply of the controller 12 energizes the electromagnetic coil 1603 in the inner recess of the pulley 1601. At this time, the armature 1604... Attracted by the energized electromagnetic coil 1603, the spring 1605 is pulled and tightly adheres to the surface of the pulley 1601, so that the collar 1606, which is coaxial with the drive shaft 15, is driven by friction to the pulley 1601 through the armature 1604. Then, the power transmission is established with the reciprocating drive assembly 17 through the transmission belt sleeved on the outside of the pulley 1601. This application monitors the change in current parameters caused by the increase in resistance when the cylinder roller 7 is winding, and drives the reciprocating drive assembly 17 to run and execute the cleaning procedure by means of the kinetic energy of the drive shaft 15 through friction transmission. It can actively intervene when the cylinder roller 7 is winding, avoid the reduction of combing efficiency due to fiber accumulation, and ensure the combing effect. Then, the driven wheel 1704 establishes power transmission with the pulley 1601 through the transmission belt, and then achieves bidirectional linear reciprocating motion through the continuous thrust of the spiral groove sidewall on the slider 1705 during the rotation of the reciprocating screw 1703. Furthermore, the front end of the slider 1705 is connected to the rod 1801 through the connecting rod 1706, so that the rod 1801 moves axially at the side end of the cylinder roller 7 under the transmission action of the reciprocating screw 1703, and returns to the inner wall of the housing 1 at the end of the stroke, so that the flower cleaning component 18 and the cylinder roller 7 are left with a gap during idle time, so as to avoid interference with the cylinder roller 7 during normal operation. Finally, during use, the extension and retraction drive of the connecting pin 1806 at the end of the cleaning hook 1804 is adjusted by the cylinder 1807, so that the cleaning hook 1804 rotates through the rotating pin 1803 located at the end of the rod 1801. By matching the inclination angle of the cleaning hook 1804 with the surface curvature of the cylinder roller 7, the fit between the polyurethane blade edge 1805 and the surface of the cylinder roller 7 is improved. Furthermore, by using polyurethane material with a hardness lower than that of the needle teeth of the cylinder roller 7, the polyurethane blade edge 1805 deforms first rather than damages the needle teeth when it comes into contact with them during the reciprocating cleaning of the tangled fibers along the axial direction of the cylinder roller 7, reducing the mechanical scraping force and thus reducing the risk of collision. In addition, by setting a negative pressure suction port at the rear of the cleaning hook 1804 and connecting it to the negative pressure pipeline 1802, the airflow is used to peel off the tangled fibers, avoiding secondary tangling of the fibers and further improving the cleaning effect.
