Description

Technical Field

[0001] This invention relates to the field of cashmere combing mechanism technology, specifically to a combing device and combing process for anti-pilling cashmere products. Background Technology

[0002] Anti-pilling cashmere products refer to cashmere products whose pilling phenomenon is effectively suppressed or reduced during daily wear. As a high-end natural fiber product, cashmere products have excellent warmth and comfort. In the production process of anti-pilling cashmere products, the cashmere raw materials must first be processed. During the manufacturing process, the cashmere raw material needs to be combed. The combing device transforms the cashmere fibers from their original state into semi-finished products suitable for subsequent spinning, weaving and other processes through a series of physical actions. This process not only involves the separation, loosening and orientation of fibers, but also achieves efficient processing of cashmere fibers through specific mechanical devices and process parameters.

[0003] Washed, oven-dried cashmere fibers are poor conductors of electricity. During cashmere processing, friction constantly occurs between the fibers and metal machinery or between the fibers themselves, generating static electricity. The accumulation of static electricity disrupts the fiber's movement, directly affecting the opening and combing of the cashmere. Cashmere fibers are softer and easier to comb at appropriate humidity levels. Moistening cashmere increases its conductivity, effectively eliminating static electricity and ensuring smooth processing. Therefore, before combing, cashmere is often sprayed with water. This increases humidity, promoting fiber loosening and even mixing, creating better conditions for subsequent combing and sliver forming processes. Before cashmere raw materials enter the carding machine, the carding machine is normally equipped with a pre-humidification device to perform preliminary water spraying treatment on the cashmere raw materials to increase their humidity and prepare for the subsequent carding process. However, in the actual production process, since cashmere is generally transported into the carding machine through a feeding hopper, the cashmere tends to tangle itself in the feeding hopper, whether it is manually or automatically fed into the feeding hopper. As a result, when it moves to the pre-humidification device, the tangled cashmere is difficult to be evenly moistened, which can easily lead to fiber damage during the carding operation. Therefore, we propose a carding device and carding process for anti-pilling cashmere products. Summary of the Invention

[0004] The purpose of this invention is to provide a combing device and combing process for anti-pilling cashmere products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a combing device for anti-pilling cashmere products, comprising a combing mechanism, a feeding hopper located on one side of the combing mechanism, and a conveying mechanism communicating with the combing mechanism and the feeding hopper, wherein a connecting frame is fixedly installed on the conveying mechanism, and a pre-wetting mechanism for spraying water on the cashmere is fixedly installed on the connecting frame.

[0006] Multiple combing frames are arranged in parallel inside the connecting frame for combing cashmere.

[0015] Preferably, when the electromagnet assembly is energized, it generates a repulsive force on the T-shaped snap-fit ​​shaft. One end of the T-shaped snap-fit ​​shaft is located outside the connecting frame, and multiple through holes are provided on the inner walls of both sides of the limiting frame. When the T-shaped snap-fit ​​shaft is subjected to the repulsive force of the electromagnet assembly, the through holes are located on the movement trajectory of the T-shaped snap-fit ​​shaft.

[0016] Preferably, a combing needle assembly is provided below the connecting frame, and a positioning rod is fixedly installed on the combing needle assembly.

[0017] Preferably, a rotating shaft is also installed inside the connecting frame and is rotatably connected thereto. A meshing gear is fixedly installed on the rotating shaft, and a meshing gear rack is fixedly installed on one side of the drive slider. The meshing gear rack and the meshing gear are in a meshing state. A rotating disk frame is fixedly installed on the rotating shaft. The rotating disk frame is provided with multiple N-pole magnetic plates and S-pole magnetic plates. The N-pole magnetic plates and S-pole magnetic plates are arranged in a ring-shaped staggered arrangement on the rotating disk frame. The magnetic surface at the top of the positioning rod frame is located on the rotation trajectory of the N-pole magnetic plates and S-pole magnetic plates.

[0018] A combing process used in a combing device for anti-pilling cashmere products specifically includes the following steps:

[0019] S1. First, the cashmere in the feeding hopper enters the combing mechanism through the conveying mechanism. During this process, the servo motor starts, the belt drive mechanism rotates, and then the drive motor starts. Its output end drives the lead screw inside the limiting frame to rotate under the transmission action of the chain wheel and chain. During the rotation of the lead screw, the drive slider on it moves in an directional manner under the action of the guide shaft. Since the drive slider and the support frame are connected through the limiting shaft, the drive slider drives the support frame to move in an directional manner. During the movement of the support frame, the connecting shaft inside it causes the connecting bracket to drive the combing frame to move in an directional manner, so as to comb the tangled cashmere.

[0020] S2. When encountering cashmere with excessive tangles, the combing frame will adjust its angle under pressure, i.e., the torsion spring will deform. During the angle adjustment process, the contact parts on the combing frame will apply force to the sensing element. The sensing element is connected to the electric magnet through an electrical signal, which in turn energizes the electric magnet, generating an attractive force on the ring magnet at the top of the support frame. Under the action of the limiting shaft, the support frame moves upward in a directional direction, thereby causing the combing frame to leave the tangled area of ​​cashmere. After the specified energizing time is reached, the electric magnet is de-energized. Then, under the action of the return spring, the support frame, under the action of the connecting shaft and the connecting bracket, drives the combing frame back to the initial position to continue combing the cashmere.

[0021] S3. When the sensing element is triggered, the electromagnet assembly is energized via an electrical signal. The end of the T-shaped locking shaft near the electromagnet assembly experiences a repulsive force from the electromagnet assembly, driving the slider to move along the connecting frame via the spring mechanism. During this movement, the other end of the T-shaped locking shaft enters the through hole, which restricts the connecting frame. In this state, the connecting frame is fixed while the spring mechanism is stretched. During the slider's movement, the meshing gear set acts on the meshing gear, causing it to rotate. The rotating shaft rotates synchronously, driving the rotating disk frame and its N-pole and S-pole magnetic plates to rotate synchronously. When the N-pole magnetic plate moves directly above the positioning rod, the N-pole magnetic plate... The magnetic surface of the positioning rod will generate a repulsive force, causing the positioning rod to drive the combing needle assembly to descend. The combing needle assembly is used to comb the cashmere that is too tangled. When the S-pole magnetic plate is directly above the magnetic surface of the positioning rod, the positioning rod will move upward in a directional direction. This is repeated multiple times. The combing needle assembly can effectively comb the cashmere that is too tangled. After the electromagnet assembly reaches the set time, it will automatically de-energize. Under the action of the spring mechanism, the connecting frame will return to the initial position. When the combing frame moves from one side of the conveying mechanism to the other side, the electromagnet will be energized, causing the combing frame to rise and no longer contact the cashmere. Then the drive motor will reverse, causing the drive slider to drive the mechanical parts on it to return to the initial position. At the same time, the servo motor will drive the belt drive mechanism to reverse, causing the limit frame to drive the mechanical parts on it to return to the initial position.

[0022] S4. The pre-wetting mechanism wets the cashmere that has been processed on the conveying mechanism. The wetted cashmere then enters the combing mechanism for combing.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention utilizes a combing frame to comb cashmere, avoiding uneven wetting of tangled cashmere during the wetting process. Under the action of the belt drive mechanism, the limiting frame and the conveying mechanism maintain the same speed. At the same time, the lead screw drives the slider to move the mechanical parts on it in a directional manner, so as to comb the tangled cashmere.

[0025] 2. This invention utilizes a combing needle assembly to comb cashmere with severe tangles. Under the action of the N-pole magnetic plate and the S-pole magnetic plate, the positioning rod frame drives the combing needle assembly to comb the cashmere with severe tangles. Through the meshing relationship of the meshing tooth row and meshing gear, the rotating shaft drives the N-pole magnetic plate and the S-pole magnetic plate to change angles through the rotating disc frame, thereby achieving the purpose of effectively combing the cashmere by controlling the positioning rod frame to drive the combing needle assembly.

Detailed Implementation

[0039] 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.

[0040] Please see Figure 1-12 This invention provides a technical solution: a combing device and combing process for anti-pilling cashmere products. This invention addresses the technical problems in the background art by making corresponding improvements, including a combing mechanism 1, a feeding hopper 2 located on one side of the combing mechanism 1, and a conveying mechanism 3 communicating with the combing mechanism 1 and the feeding hopper 2. A connecting frame 4 is also fixedly installed on the conveying mechanism 3, and a pre-wetting mechanism 5 for spraying water onto the cashmere is fixedly installed on the connecting frame 4. (See attached diagram.) Figure 1-2 As shown, the cashmere entering the feeding hopper 2 passes through the conveying mechanism 3 and enters the combing mechanism 1. During this process, the pre-wetting mechanism 5 sprays water on the cashmere on the conveying mechanism 3 to wet the cashmere. However, due to the entanglement between some cashmere fibers, some cashmere fibers are often not wetted. To address this, the present invention is designed as follows.

[0041] First, a servo motor 43 is fixedly installed on the outer wall of the connecting frame 4. The servo motor 43 can be fixed to the outer wall of the connecting frame 4 by bolts or welding. The output end of the servo motor 43 passes through the outer wall of the connecting frame 4 and extends into its interior. A belt drive mechanism 42 is symmetrically arranged inside the connecting frame 4. The output end of the servo motor 43 is connected to the belt drive mechanism 42. When the servo motor 43 starts, the belt drive mechanism 42 moves synchronously with it. Multiple limit frames 41 are fixedly installed on the belt drive mechanism 42. It should be noted that the movement speed of the belt drive mechanism 42 is the same as the movement speed of the conveying mechanism 3. The two sides of the limit frame 41 are slidably connected to the inner wall of the connecting frame 4. A connecting mechanism 7 is arranged inside the limit frame 41. A combing frame 6 is connected to the connecting mechanism 7. A power mechanism 8 for driving the directional movement of the connecting mechanism 7 is arranged on the limit frame 41. Under the action of the power mechanism 8, the connecting mechanism 7 drives the combing frame 6 to perform directional movement.

[0042] As a further limitation of the present invention, the power mechanism 8 includes a drive motor 81 fixedly installed outside one of the limiting frames 41, and a lead screw 82 rotatably connected to the inner wall of each limiting frame 41 is installed inside each limiting frame 41. The connecting mechanism 7 is installed on the lead screw 82. One end of the lead screw 82 passes through the inner wall of the limiting frame 41 and extends to the outside. The output end of the drive motor 81 is fixedly connected to one of the lead screws 82. A chain wheel 83 is fixedly installed at the end of each lead screw 82 located outside the limiting frame 41, and the chain wheels 83 are connected to each other through chain drive. Figure 3As shown, the drive motor 81 starts, and its output drives one of the chain wheels 83 to rotate. Under the transmission action of the chain wheel 83 and the chain, the lead screw 82 rotates in a specific direction. The connecting mechanism 7 in this invention includes a drive slider 71 mounted on the lead screw 82, and guide shafts 72 are symmetrically mounted inside the limiting frame 41. The drive slider 71 slides at the upper limit of the guide shaft 72. A support frame 73 is provided below the drive slider 71, and limiting shafts 74 are symmetrically mounted on the support frame 73. The limiting shafts 74 are slidably connected to the drive slider 71. Therefore, when the lead screw 82 rotates, the drive slider 71 moves in a specific direction under the action of the guide shaft 72. During the movement, the drive slider 71 drives the support frame 73 to move synchronously under the action of the limiting shaft 74. A component is fixedly installed inside the support frame 73. A connecting shaft 731 is connected to a connecting bracket 61 fixedly mounted on the combing frame 6, and the connecting bracket 61 is rotatably connected to the connecting shaft 731. A torsion spring 62 is connected between the connecting bracket 61 and the inner wall of the support frame 73. A contact element 63 is fixedly mounted on the connecting bracket 61, and a sensing element 732 is fixedly mounted on the inner wall of the support frame 73. The sensing element 732 is located on the movement trajectory of the contact element 63. An electric magnet 711 is fixedly mounted at the bottom of the drive slider 71, and an annular magnet 733 is fixedly mounted at the top of the support frame 73. The annular magnet 733 is located directly below the electric magnet 711. When the electric magnet 711 is energized, it generates an attractive force on the annular magnet 733. A return spring 741 is sleeved on the limiting shaft 74. The two ends of the return spring 741 are respectively connected to the bottom of the drive slider 71 and the top of the support frame 73.

[0043] Step a: Combine with the appendix Figure 1-5 As shown, the cashmere in the feeding hopper 2 first enters the combing mechanism 1 through the conveying mechanism 3. During this process, the servo motor 43 starts, the belt drive mechanism 42 rotates, and the belt drive mechanism 42 moves at the same speed as the conveying mechanism 3. Then, the combing frame 6 moves at the same speed as the cashmere. Subsequently, the drive motor 81 starts, and its output end drives the screw 82 inside the limiting frame 41 to rotate under the transmission action of the chain wheel 83 and the chain. During the rotation of the screw 82, the drive slider 71 on it moves in an directional manner under the action of the guide shaft 72. Since the drive slider 71 is connected to the support frame 73 through the limiting shaft 74, the drive slider 71 drives the support frame 73 to move in an directional manner. During the movement of the support frame 73, the connecting bracket 61 drives the combing frame 6 to move in an directional manner under the action of the connecting shaft 731 inside, so as to comb the tangled cashmere.

[0044] Furthermore, in conjunction with the appendix Figure 4As shown, the carding frame 6 is always in contact with the cashmere, thus effectively carding the cashmere and facilitating the pre-wetting mechanism 5 to spray water onto the cashmere. However, in actual operation, some cashmere may inevitably be severely tangled. Forcibly carding such cashmere can easily damage the fibers. Therefore, when encountering severely tangled cashmere, the carding frame 6 will adjust its angle under pressure, i.e., the torsion spring 62 will deform. In this invention, a torsion spring 62 with a low elastic coefficient is preferably used so that the carding frame 6 can rotate after being subjected to a certain force. During the angle adjustment process, the contact element 63 on the carding frame 6 applies a force to the sensing element 732. 2 is connected to the electric magnet 711 via an electrical signal, thereby energizing the electric magnet 711 to generate an attractive force on the annular magnet 733 at the top of the support frame 73. Under the action of the limiting shaft 74, the support frame 73 moves upward in a directional direction, thereby causing the combing frame 6 to leave the cashmere tangled area. Since the combing frame 6 is arranged in a straight line, it will not pull the cashmere during the upward process. After the set sensing element 732 is touched, the energizing time of the electric magnet 711 is set so that the combing frame 6 passes the cashmere tangled area. After the specified energizing time is reached, the electric magnet 711 is de-energized. Then, under the action of the return spring 741, the support frame 73, under the action of the connecting shaft 731 and the connecting bracket 61, drives the combing frame 6 back to the initial position to continue combing the cashmere.

[0045] To comb through severely tangled cashmere, this invention incorporates the following design: A connecting frame 9 is provided on one side of the drive slider 71. The connecting frame 9 slides at an upper limit on the guide shaft 72. A spring mechanism 91 connects the connecting frame 9 and the drive slider 71, allowing the drive slider 71 to move in a directional manner via the spring mechanism 91. An electromagnet assembly 92 is fixedly installed inside the connecting frame 9, and T-shaped locking shafts 93 are provided on both sides of the electromagnet assembly 92. The T-shaped locking shafts 93 are slidably connected to the connecting frame 9, and a constant force spring 94 connects the T-shaped locking shafts 93 to the inner wall of the connecting frame 9. When the electromagnet assembly 92 is energized, it generates a repulsive force on the T-shaped locking shafts 93. One end of the T-shaped locking shaft 93 is located outside the connecting frame 9. Multiple springs are provided on the inner walls of both sides of the limiting frame 41. When the T-shaped snap-fit ​​shaft 93 is subjected to the repulsive force of the electromagnet assembly 92, the through hole 411 is located on the movement trajectory of the T-shaped snap-fit ​​shaft 93. To further explain, under normal circumstances, the electromagnet assembly 92 is not energized, and the end of the T-shaped snap-fit ​​shaft 93 will not enter the through hole 411. The electromagnet assembly 92 is electrically connected to the sensing element 732. When the sensing element 732 is triggered, the electromagnet assembly 92 is energized to generate a repulsive force on the T-shaped snap-fit ​​shaft 93 (the end of the T-shaped snap-fit ​​shaft 93 closest to the electromagnet assembly 92 is the magnetic surface). The other end of the T-shaped snap-fit ​​shaft 93 will enter the through hole 411 during the movement. Under the action of the through hole 411, the connecting frame 9 is confined. Thus, in this state, during the movement of the driven slider 71, the connecting frame 9 is in a fixed state, and the spring mechanism 91 is in a stretched state.

[0046] Below the connecting frame 9, a combing needle assembly 95 is also provided, and a positioning rod 96 is fixedly installed on the combing needle assembly 95. The positioning rod 96 is slidably connected to the connecting frame 9. A fixed shaft 97 is also installed inside the connecting frame 9. The positioning rod 96 slides at its upper limit on the fixed shaft 97, and a spring body 98 is sleeved on the fixed shaft 97. The two ends of the spring body 98 are respectively connected to the positioning rod 96 and the inner top wall of the connecting frame 9. The top of the positioning rod 96 is magnetic. A rotating shaft that is rotatably connected to it is also installed inside the connecting frame 9. 99, and a meshing gear 90 is fixedly installed on the rotating shaft 99, and a meshing gear row 75 is fixedly installed on one side of the drive slider 71. The meshing gear row 75 and the meshing gear 90 are in a meshing state. A rotating disk frame 901 is fixedly installed on the rotating shaft 99. The rotating disk frame 901 is provided with multiple N pole magnetic plates 902 and S pole magnetic plates 903. The N pole magnetic plates 902 and S pole magnetic plates 903 are arranged in a ring-shaped staggered arrangement on the rotating disk frame 901. The magnetic surface at the top of the positioning rod frame 96 is located on the rotation trajectory of the N pole magnetic plates 902 and S pole magnetic plates 903.

[0047] Step b: Combine with the appendix Figure 7-12 As shown: When the sensing element 732 is triggered, it controls the electromagnet assembly 92 to be energized in the form of an electrical signal. Consequently, the end of the T-shaped locking shaft 93 closest to the electromagnet assembly 92 experiences a repulsive force from the electromagnet assembly 92. This drives the slider 71 to move along the connecting frame 9 via the spring mechanism 91. During this movement, the other end of the T-shaped locking shaft 93 enters the through hole 411, which, under the action of the through hole 411, confines the connecting frame 9. Therefore, in this state, during the movement of the slider 71, the connecting frame 9 is in a controlled position. In a fixed state, with the spring mechanism 91 in a stretched state, and the driving slider 71 in motion, the meshing tooth row 75 acts on the meshing gear 90, causing the meshing gear 90 to rotate. It should be noted that the meshing tooth row 75 has teeth in some areas. When the meshing gear 90 rotates, the rotating shaft 99 rotates synchronously, driving the rotating disk frame 901 and its N-pole magnetic plate 902 and S-pole magnetic plate 903 to rotate synchronously. It should also be noted that the magnetic surface at the top of the positioning rod frame 96 is the N-pole. Figure 11 As shown, when the N-pole magnetic plate 902 moves directly above the positioning rod 96, it generates a repulsive force on the magnetic surface of the positioning rod 96, causing the positioning rod 96 to drive the combing needle assembly 95 to descend. The combing needle assembly 95 then combs the cashmere that is severely tangled, effectively alleviating the tangling. When the S-pole magnetic plate 903 is directly above the magnetic surface of the positioning rod 96, the positioning rod 96 will move upward in a directional direction. This process is repeated multiple times, allowing the combing needle assembly 95 to effectively comb the cashmere that is severely tangled. After the electromagnet assembly 92 reaches the set time, it automatically de-energizes, and the connecting frame 9 returns to its initial position under the action of the spring mechanism 91. When the combing frame 6 moves from one side of the conveying mechanism 3 to the other side... When the electric magnet 711 is energized, the combing frame 6 rises and no longer contacts the cashmere. Then, the drive motor 81 reverses, and the reverse speed is greater than the initial forward speed, causing the drive slider 71 to bring its mechanical parts back to the initial position. At the same time, the servo motor 43 drives the belt drive mechanism 42 to reverse, causing the limit frame 41 to bring its mechanical parts back to the initial position. Since there are multiple limit frames 41 and mechanical parts on them, the combing work on the cashmere on the conveying mechanism 3 can be ensured, thereby ensuring that the pre-wetting mechanism 5 can effectively wet the cashmere. This reduces the situation where the cashmere fibers are damaged due to severe tangling during the subsequent combing operation in the combing mechanism 1. Therefore, under the structural design of the present invention, the combing quality of cashmere can be effectively improved.

[0048] A combing process used in a combing device for anti-pilling cashmere products specifically includes the following steps:

[0049] S1. First, the cashmere in the feeding hopper 2 enters the combing mechanism 1 through the conveying mechanism 3. During this process, the servo motor 43 starts, the belt drive mechanism 42 rotates, and then the drive motor 81 starts. Its output end drives the lead screw 82 inside the limiting frame 41 to rotate under the transmission action of the chain wheel 83 and the chain. During the rotation of the lead screw 82, the drive slider 71 on it moves in an directional manner under the action of the guide shaft 72. Since the drive slider 71 is connected to the support frame 73 through the limiting shaft 74, the drive slider 71 drives the support frame 73 to move in an directional manner. During the movement of the support frame 73, the connecting bracket 61 drives the combing frame 6 to move in an directional manner under the action of the connecting shaft 731 inside it, so as to comb the tangled cashmere.

[0050] S2. When encountering cashmere with excessive tangles, the combing frame 6 will adjust its angle under pressure, i.e., the torsion spring 62 will deform. During the angle adjustment process, the contact element 63 on the combing frame 6 will apply a force to the sensing element 732. The sensing element 732 is connected to the electric magnet 711 via an electrical signal, which energizes the electric magnet 711 to generate an attractive force on the annular magnet 733 at the top of the support frame 73. Under the action of the limiting shaft 74, the support frame 73 moves upward in a directional direction, thereby causing the combing frame 6 to leave the tangled area of ​​cashmere. After the specified energizing time is reached, the electric magnet 711 is de-energized. Then, under the action of the return spring 741, the support frame 73, under the action of the connecting shaft 731 and the connecting bracket 61, drives the combing frame 6 back to the initial position to continue combing the cashmere.

[0051] S3. When the sensing element 732 is triggered, it controls the electromagnet assembly 92 to be energized in the form of an electrical signal. This causes the T-shaped locking shaft 93, near the electromagnet assembly 92, to experience a repulsive force from the electromagnet assembly 92. This, in turn, drives the slider 71 to move along the connecting frame 9 via the spring mechanism 91. During this movement, the other end of the T-shaped locking shaft 93 enters the through hole 411, which restricts the connecting frame 9. In this state, the connecting frame 9 is fixed while the slider 71 is in motion, and the spring mechanism 91 is stretched. During the movement of the slider 71, the meshing gear 75 acts on the meshing gear 90, causing it to rotate. The rotating shaft 99 rotates synchronously with it, driving the rotating disk frame 901 and its N-pole magnetic plate 902 and S-pole magnetic plate 903 to rotate synchronously. When the N-pole magnetic plate 902 moves directly above the positioning rod frame 96... The N-pole magnetic plate 902 generates a repulsive force on the magnetic surface of the positioning rod 96, causing the positioning rod 96 to drive the combing needle assembly 95 to descend. The combing needle assembly 95 is used to comb the cashmere that is too tangled. When the S-pole magnetic plate 903 is directly above the magnetic surface of the positioning rod 96, the positioning rod 96 will move upward in a directional direction. After repeated multiple times, the combing needle assembly 95 can effectively comb the cashmere that is too tangled. After the electromagnet assembly 92 reaches the set time, it will automatically de-energize. Under the action of the spring mechanism 91, the connecting frame 9 returns to the initial position. When the combing frame 6 moves from one side of the conveying mechanism 3 to the other side, the electric magnet 711 is energized, causing the combing frame 6 to rise and no longer contact the cashmere. Then the drive motor 81 reverses, causing the drive slider 71 to drive the mechanical parts on it to return to the initial position. At the same time, the servo motor 43 drives the belt drive mechanism 42 to reverse, causing the limit frame 41 to drive the mechanical parts on it to return to the initial position.

[0052] S4. The pre-wetting mechanism 5 wets the cashmere that has been processed on the conveying mechanism 3. The wetted cashmere then enters the combing mechanism 1 for combing.

The N-pole magnetic plates (902) and S-pole magnetic plates (903) are arranged in a ring-shaped staggered arrangement on the rotating disk frame (901).

7. The combing process used in the combing device for anti-pilling cashmere products according to claim 6 specifically includes the following steps: S1. First, the cashmere in the feeding hopper (2) enters the combing mechanism (1) through the conveying mechanism (3). During this process, the servo motor (43) starts, the belt drive mechanism (42) rotates, and then the drive motor (81) starts. Its output end drives the screw (82) inside the limiting frame (41) to rotate under the transmission action of the chain wheel (83) and the chain. During the rotation of the screw (82), the drive slider (71) on it moves in an directional manner under the action of the guide shaft (72). Since the drive slider (71) and the support frame (73) are connected through the limiting shaft (74), the drive slider (71) drives the support frame (73) to move in an directional manner. During the movement of the support frame (73), the connecting shaft (731) inside it causes the connecting bracket (61) to drive the combing frame (6) to move in an directional manner, so as to comb the tangled cashmere. S2. When encountering cashmere with excessive tangling, the combing frame (6) will adjust its angle when subjected to action, that is, the torsion spring (62) will deform. During the angle adjustment of the combing frame (6), the contact part (63) on it will apply force to the sensing element (732). The sensing element (732) is connected to the electric magnet (711) through an electrical signal. Then the electric magnet (711) is energized to generate an attraction force on the ring magnet (733) at the top of the support frame (73). The support frame (73) moves upward under the action of the limiting shaft (74), so that the combing frame (6) leaves the cashmere tangling area. After the specified energizing time is reached, the electric magnet (711) is de-energized. Then, under the action of the return spring (741), the support frame (73) drives the combing frame (6) back to the initial position under the action of the connecting shaft (731) and the connecting bracket (61) to continue combing the cashmere. S3. When the sensing element (732) is triggered, the electromagnet assembly (92) is energized in the form of an electrical signal. As a result, the end of the T-shaped locking shaft (93) near the electromagnet assembly (92) is subjected to the repulsive force of the electromagnet assembly (92), which in turn drives the slider (71) to move the connecting frame (9) through the spring mechanism (91). During the movement, the other end of the T-shaped locking shaft (93) will enter the through hole (411). Under the action of the through hole (411), the connecting frame (9) is confined. Thus, in this state, During the movement of the drive slider (71), the connecting frame (9) is in a fixed state, and the spring mechanism (91) is in a stretched state. During the movement of the drive slider (71), the meshing gear row (75) will act on the meshing gear (90) to make the meshing gear (90) rotate. The rotating shaft (99) will rotate synchronously with it, and during the rotation, it will drive the rotating disk frame (901) and the N pole magnetic plate (902) and S pole magnetic plate (903) on it to rotate synchronously. The N pole magnetic plate (902) moves to the positioning rod frame (96). When directly above, the N-pole magnetic plate (902) generates a repulsive force on the magnetic surface of the positioning rod (96), causing the positioning rod (96) to drive the combing needle assembly (95) to descend. The combing needle assembly (95) is used to comb the cashmere that is too tangled. When the S-pole magnetic plate (903) is directly above the magnetic surface of the positioning rod (96), the positioning rod (96) will move upward in a directional direction. After repeated movements, the combing needle assembly (95) can effectively comb the cashmere that is too tangled, and the electromagnet assembly (92) reaches the set position. After a certain time, the power is automatically cut off, and the connecting frame (9) returns to its initial position under the action of the spring mechanism (91). When the combing frame (6) moves from one side of the conveying mechanism (3) to the other side, the electric magnet (711) is energized, causing the combing frame (6) to rise and no longer contact the cashmere. Then the drive motor (81) reverses, causing the drive slider (71) to drive the mechanical parts on it back to the initial position. At the same time, the servo motor (43) drives the belt drive mechanism (42) to reverse, causing the limit frame (41) to drive the mechanical parts on it back to the initial position. S4. The pre-wetting mechanism (5) wets the cashmere that has been processed on the conveying mechanism (3). The wetted cashmere enters the combing mechanism (1) for combing.
