Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, specifically to a silk strip dyeing and combing device and its combing method. Background Technology

[0002] Silk strip dyeing and combing is a special textile process. First, in the dyeing stage, the silk strips undergo strip dyeing, which dyes the strips into various colors. Then, the excess dye is removed through re-dyeing, making the colors more even and accurate. Next, in the combing stage, the silk strips of various colors are thoroughly mixed, and then combed again to further organize the fiber arrangement, improve the fiber uniformity and the removal rate of yarn defects, and finally obtain the mixed-color silk strips for use in the previous spinning stage.

[0003] First, the raw silk needs to undergo a dyeing process to give it the desired color. During the dyeing process, it is necessary to ensure that the silk is dyed evenly while maintaining its original fiber characteristics. Next is the combing process, which is equally important in silk processing. It is mainly used to remove lint and clumps that may be generated during the dyeing process, as well as to eliminate fiber tangles and knots. Through combing, the fiber quality of the silk can be further improved, making it smoother and softer, and reducing impurities and short fibers in the fiber.

[0004] In the combing process of silk slivers, the top comb plays a crucial role. It is primarily responsible for finely combing the silk fibers, removing short fibers and impurities to improve fiber parallelism and straightness, thereby enhancing the quality of the silk sliver. In actual operation, the top comb uses multiple needle groups to comb the silk sliver. However, during prolonged use, some needle groups on the top comb may bend and deform due to the significant combing force. Bending needle groups not only impair the normal combing function of the top comb, reducing the combing effect, but also increase friction during the combing process, causing greater damage to the silk sliver. This not only damages the fiber integrity but may also generate more short fibers and impurities, further reducing the quality of the silk sliver. Furthermore, bending needles may cause fiber breakage and entanglement during combing, resulting in uneven fiber distribution within the silk sliver. This affects the uniformity and softness of the silk sliver, making the final product prone to problems such as pilling and fuzzing during use. Therefore, we propose a silk sliver dyeing and refining combing device and its combing method. Summary of the Invention

[0005] The purpose of this invention is to provide a silk strip dyeing and combing device and a combing method thereof to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silk sliver dyeing and combing device, comprising a combing mechanism, a top comb plate frame installed inside the combing mechanism, and multiple needle groups A disposed inside the top comb plate frame, wherein one end of each needle group A is located outside the top comb plate frame. Multiple mounting frames are fixedly installed at the bottom of the top comb plate frame, each mounting frame corresponding one-to-one with a needle group A. Each mounting frame contains a symmetrically arranged arc-shaped placement frame, and each arc-shaped placement frame contains a fixedly installed arc-shaped rubber pad, the arc-shaped rubber pad being tightly fitted to the corresponding needle group A. The mounting frame is combined with a sliding shaft fixedly installed on both sides of each arc-shaped placement frame. The inner walls of the mounting frames on both sides are symmetrically provided with inclined grooves. The sliding shaft slides within the inclined grooves and a sensing element is installed within the inclined grooves. The sensing element is located on the movement trajectory of the sliding shaft. The top comb plate frame is provided with multiple connectors for fixing the needle group A. The top comb plate frame is also provided with a belt transmission mechanism. The belt transmission mechanism is equipped with multiple magnetic mechanisms for controlling the lifting and lowering movement of the needle group A through the connectors.

[0007] Preferably, each of the mounting frames is symmetrically equipped with a movable plate frame that is slidably connected to its top and bottom inner walls. The movable plate frame corresponds one-to-one with the arc-shaped placement frame, and a limiting shaft is fixedly installed inside the movable plate frame. The arc-shaped placement frame slides at the upper limit of the limiting shaft, and a buffer spring connects the movable plate frame to the inner wall of the mounting frame.

[0008] Preferably, an air suction pipe is also fixedly installed on the mounting frame for sucking up and cleaning the fibers wrapped around the needle assembly A.

[0009] Preferably, the top comb plate frame is internally fixedly installed with multiple fixed frames, and each fixed frame corresponds one-to-one with the needle group A. Each fixed frame is internally installed with two sliding frames, and the sliding frames are fixedly connected to each other. Each sliding frame is symmetrically equipped with a guide shaft.

[0010] Preferably, the connector includes a connecting sleeve, and a connecting sleeve is provided below each sliding frame. The top of the connecting sleeve is a magnetic surface, and the connecting sleeve is slidably connected to the guide shaft. The needle group A is fixedly installed inside one of the connecting sleeves, and a spare needle group B is installed inside the other connecting sleeve.

[0011] Preferably, each of the sliding frames and connecting sleeves is equipped with a magnetic sleeve, and the magnetic properties of the magnetic sleeves on the sliding frames and connecting sleeves are opposite.

[0012] Preferably, an electromagnetic component is fixedly installed on one side of the fixed frame, and a force-receiving magnetic plate is fixedly installed on the side of the sliding frame close to the electromagnetic component, and the electromagnetic component generates a repulsive force on the force-receiving magnetic plate when energized.

[0013] Preferably, the belt transmission mechanism includes pulleys symmetrically arranged inside the top comb plate frame, and the pulleys are connected to each other by a belt body. A fixed shaft is fixedly installed inside the top comb plate frame, one of the pulleys is mounted on the fixed shaft and rotatably connected to it, a limiting sleeve is also fixedly installed inside the top comb plate frame, and a rotating sleeve is rotatably connected to it inside the limiting sleeve, and the other pulley is fixedly installed on the rotating sleeve.

[0014] The belt body is also equipped with multiple connecting plate frames, which correspond one-to-one with the fixed frame. The magnetic mechanism includes force-applying magnetic plate A and force-applying magnetic plate B installed on the connecting plate frames. The connecting sleeve corresponding to the needle group A is located on the movement trajectory of force-applying magnetic plate A and force-applying magnetic plate B. Force-applying magnetic plate A generates a repulsive force on the top of the connecting sleeve, and force-applying magnetic plate B generates an attractive force on the top of the connecting sleeve. The magnetic force of force-applying magnetic plate A on the top of the connecting sleeve is greater than the magnetic force of the magnetic sleeve on the sliding frame on the magnetic sleeve on the connecting sleeve.

[0015] Preferably, a support shaft is also fixedly installed inside the top comb plate frame. The support shaft is located inside the rotating sleeve. A threaded shaft that is slidably connected to the outer wall of the support shaft is installed on the support shaft. A plurality of rolling balls are installed on the inner wall of the rotating sleeve. The rolling balls slide within the threaded grooves on the threaded shaft. An annular magnetic plate is installed at one end of the threaded shaft. An electric magnetic plate is fixedly installed on one side of the top comb plate frame, and the electric magnetic plate generates a repulsive force on the annular magnetic plate. A constant force spring is connected between the other end of the threaded shaft and the inner wall of the top comb plate frame.

[0016] A combing method for a silk strip dyeing and combing device specifically includes the following steps:

[0017] S1. During the combing process of the silk slivers, multiple needle groups A on the top comb plate frame comb the silk slivers and periodically test the curvature of the needle groups A. During the test, the electric magnetic plate is energized, generating a repulsive force on the annular magnetic plate. The threaded shaft slides at the upper limit of the support shaft and compresses the constant force spring. The rotating sleeve rotates within the limiting sleeve under the action of the rolling ball. The rotating sleeve drives one of the pulleys to rotate, and the pulley drives another pulley to rotate through the belt body. As a result, the connecting plate frame on it moves. The force-applying magnetic plate A located directly above the needle group A moves away, and the force-applying magnetic plate B is located directly above the needle group A, that is, directly above the connecting sleeve. The force-applying magnetic plate B generates an attractive force on the connecting sleeve, and the connecting sleeve drives the needle group A to move upward.

[0018] S2. During the upward movement of needle assembly A, it remains in contact with the arc-shaped rubber pad. If needle assembly A bends, it will act on the arc-shaped rubber pad during the upward movement. The arc-shaped rubber pad and the arc-shaped placement frame move synchronously upward. The sliding shaft on the arc-shaped placement frame moves along the trajectory of the inclined groove and touches the sensing element during the movement, indicating that needle assembly A has bent and needs to be replaced. As the sliding shaft on the arc-shaped placement frame moves along the trajectory of the inclined groove, the arc-shaped rubber pad gradually separates from needle assembly A. When the connecting sleeve rises to the end, the magnetic sleeve on the connecting sleeve contacts the magnetic sleeve on the sliding frame. At this time, needle assembly A is located inside the top comb plate frame.

[0019] S3. During the ascent, the suction pipe sucks up the fibrous impurities on the surface of needle assembly A to clean them.

[0020] S4. When the bent needle assembly A enters the top comb plate frame, the electromagnetic component is energized to generate a repulsive force on the force-bearing magnetic plate on one side of one of the sliding frames. The sliding frame corresponding to needle assembly A slides within the fixed frame, and the sliding frame corresponding to the spare needle assembly B moves to the initial position of the sliding frame corresponding to needle assembly A. At this time, the bent needle assembly A has been replaced, and needle assembly B moves directly below the force-bearing magnetic plate B, while needle assembly A is no longer directly below the force-bearing magnetic plate B. Subsequently, the electric magnetic plate is de-energized, and the threaded shaft returns to its initial position under the action of the constant force spring, that is, the force-bearing magnetic plate A returns to its initial position, generating a repulsive force on needle assembly B, so that needle assembly B descends to the position for combing the silk strips, thereby achieving the purpose of replacing the bent combing needle assembly.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention utilizes an arc-shaped rubber pad in contact with needle assembly A, and detects whether the needle assembly A is bent based on its cross-sectional area. During the upward movement of the bent needle assembly A, a force is applied to the arc-shaped rubber pad. Through the positional relationship between the sliding shaft and the inclined groove on the arc-shaped frame, the sliding shaft applies a force to the sensing element within the inclined groove during movement. This effectively detects the bending condition of the needle assembly A, preventing uneven fiber distribution in the silk sliver due to the bent needle assembly A, thereby improving the quality of the silk sliver combing.

[0023] This invention utilizes a spare needle group B to replace the bent needle group A, thereby achieving the purpose of automatically changing the needle group during the combing of silk slivers and improving work efficiency.

[0024] This invention utilizes an air suction pipe to remove fibrous impurities from needle group A or spare needle group B, thereby improving the combing quality of silk slivers. Attached Figure Description

Detailed Implementation

[0038] 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.

[0039] Please see Figure 1-12 This invention provides a technical solution: a silk sliver dyeing and combing device. This invention addresses the technical problems in the background art by making corresponding improvements, including a combing mechanism 1, a top comb plate frame 2 installed inside the combing mechanism 1, and further, the combing mechanism 1 of this invention also includes combing components such as a cylinder. Since the combing components are existing technology, this invention does not describe them in detail. It also includes multiple needle groups A3 installed inside the top comb plate frame 2, with one end of each needle group A3 located outside the top comb plate frame 2. It should be noted that, for convenience... The invention describes a needle assembly A3 for combing silk threads. Multiple mounting frames 21 are fixedly installed at the bottom of the top comb plate 2, each corresponding to a needle assembly A3. Suction pipes 24 are also fixedly installed on the mounting frames 21 to absorb and clean the fibers wrapped around the needle assembly A3. Each mounting frame 21 has symmetrically arranged arc-shaped placement frames 22 inside, and each arc-shaped placement frame 22 has an arc-shaped rubber pad 221 fixedly installed inside. The arc-shaped rubber pad 221 is tightly connected to the corresponding needle assembly A3. Figure 5-7As shown, two arc-shaped rubber pads 221 combine to form a complete rubber ring, which wraps around the needle assembly A3. Generally, if the needle assembly A3 bends, the end area (i.e., the head area) of the needle assembly A3 will bend. Sliding shafts 222 are fixedly installed on both sides of each arc-shaped placement frame 22. The inner walls of both sides of the mounting frame 21 are symmetrically provided with inclined grooves 23. The sliding shafts 222 slide within the inclined grooves 23, and sensing elements 231 are installed within the inclined grooves 23, located on the movement trajectory of the sliding shafts 222. Each mounting frame 21 is symmetrically equipped with a movable plate frame 211 that slides slidably on its top and bottom inner walls. The movable plate frame 211 corresponds one-to-one with the arc-shaped placement frame 22, and the movable plate frame 211... The movable plate frame 211 is fixedly installed with a limiting shaft 212. The arc-shaped placement frame 22 slides at the upper limit of the limiting shaft 212. A buffer spring 213 is connected between the movable plate frame 211 and the inner wall of the mounting frame 21. When the needle group A3 moves upward, if the needle group A3 does not bend, the needle group A3 passes through the arc-shaped rubber pad 221. However, if it bends, the cross-sectional area of ​​the needle group A3 will increase, and a force will be applied to the arc-shaped rubber pad 221 during the upward movement. The top comb plate frame 2 is also provided with multiple connecting parts 4 for fixing the needle group A3. The top comb plate frame 2 is also provided with a belt transmission mechanism 5. Multiple magnetic mechanisms 6 are installed on the belt transmission mechanism 5 to control the lifting and lowering movement of the needle group A3 through the connecting parts 4.

[0040] The top comb plate frame 2 has multiple fixed frames 7 fixedly installed inside, and each fixed frame 7 corresponds one-to-one with the needle assembly A3. Each fixed frame 7 also has two sliding frames 71 installed inside, and the sliding frames 71 are fixedly connected. Each sliding frame 71 is symmetrically equipped with a guide shaft 72. As a further limitation of this invention, the connector 4 includes a connecting sleeve 41. Each sliding frame 71 has a connecting sleeve 41 below it. The top of the connecting sleeve 41 is magnetic, and the connecting sleeve 41 is slidably connected to the guide shaft 72. The needle assembly A3 is fixedly installed within it. Inside one connecting sleeve 41, and inside the other connecting sleeve 41, a spare needle assembly B42 is installed. The spare needle assembly B42 is used to replace the bent needle assembly A3. Each sliding frame 71 and connecting sleeve 41 is equipped with a magnetic sleeve 8, and the magnetic properties of the sliding frame 71 and the magnetic sleeve 8 on the connecting sleeve 41 are opposite. An electromagnetic component 73 is fixedly installed on one side of the fixed frame 7, and a force-receiving magnetic plate 74 is fixedly installed on the side of the sliding frame 71 close to the electromagnetic component 73. When the electromagnetic component 73 is energized, it generates a repulsive force on the force-receiving magnetic plate 74.

[0041] As a further limitation of the present invention, the belt transmission mechanism 5 includes pulleys 51 symmetrically arranged inside the top comb plate frame 2, and the pulleys 51 are connected to each other via a belt body 52. ​​A fixed shaft 26 is fixedly installed inside the top comb plate frame 2, one of the pulleys 51 is mounted on the fixed shaft 26 and rotatably connected to it. A limiting sleeve 27 is also fixedly installed inside the top comb plate frame 2, and a rotating sleeve 28 rotatably connected to it is installed inside the limiting sleeve 27. The other pulley 51 is fixedly mounted on... Mounted on the rotating sleeve 28, the belt body 52 is also equipped with multiple connecting plate frames 29, which correspond one-to-one with the fixed frame 7. The magnetic mechanism 6 includes force-applying magnetic plates A61 and B62 mounted on the connecting plate frames 29. The connecting sleeve 41 corresponding to the needle group A3 is located on the movement trajectory of the force-applying magnetic plates A61 and B62. The force-applying magnetic plate A61 generates a repulsive force on the top of the connecting sleeve 41, and the force-applying magnetic plate B62 generates an attractive force on the top of the connecting sleeve 41. The magnetic force exerted by the force-applying magnetic plate A61 on the top of the connecting sleeve 41 is greater than the magnetic force exerted by the magnetic sleeve 8 on the sliding frame 71 on the connecting sleeve 41. In the initial state, i.e., during the combing operation of the needle assembly A3 on the silk sliver, the force-applying magnetic plate A61 is located directly above the connecting sleeve 41 corresponding to the needle assembly A3, thereby generating a repulsive force on the connecting sleeve 41 corresponding to the needle assembly A3. A support shaft 25 is also fixedly installed inside the top comb plate frame 2, and the support shaft 25 is located inside the rotating sleeve 28. The support shaft 25 is equipped with a threaded shaft 10 that is slidably connected to its outer wall. The inner wall of the rotating sleeve 28 is equipped with multiple rolling balls 281. The rolling balls 281 slide within the threaded groove on the threaded shaft 10. One end of the threaded shaft 10 is equipped with an annular magnetic plate 101. One side of the top comb plate frame 2 is fixedly equipped with an electric magnetic plate 20, and the electric magnetic plate 20 generates a repulsive force on the annular magnetic plate 101. The other end of the threaded shaft 10 is connected to the inner wall of the top comb plate frame 2 with a constant force spring 9.

[0042] As a specific embodiment of the present invention: Step one, during the fine combing of the silk sliver, the bending degree of the needle group A3 on the top comb plate frame 2 is periodically detected. During the detection, the electric magnetic plate 20 is first energized, which generates a repulsive force on the annular magnetic plate 101 at one end of the threaded shaft 10. Then, the threaded shaft 10 slides on the support shaft 25 in a limited position. During the sliding process, the threaded shaft 10 compresses the constant force spring 9. During the directional movement of the threaded shaft 10, the multiple rolling balls 281 on the inner wall of the rotating sleeve 28 are subjected to the thread groove on the threaded shaft 10. That is, the rotating sleeve 28 rotates in a directional manner within the limiting sleeve 27, thereby causing one of the pulleys 51 to rotate and drive the other pulley 51 through the belt body 52. The belt body 52 rotates synchronously, and during the movement, the connecting plate frame 29 and the force-applying magnetic plates A61 and B62 on it move synchronously. That is, in the initial state, the force-applying magnetic plate A61 is located directly above the connecting sleeve 41 corresponding to the needle group A3, so as to generate a repulsive force on the connecting sleeve 41 corresponding to the needle group A3. When the connection moves, the force-applying magnetic plate A61 moves away from the connecting sleeve 41 corresponding to the needle group A3, and the force-applying magnetic plate B62 moves to the directly above the connecting sleeve 41 corresponding to the needle group A3. Then, the force-applying magnetic plate B62 generates an attractive force on the connecting sleeve 41, so that the connecting sleeve 41 drives the needle group A3 to move upward. During the upward movement, the suction pipe 24 sucks up and cleans the fiber impurities on the surface of the needle group A3.

[0043] Step 2: If needle assembly A3 is bent, its cross-sectional area will increase. As needle assembly A3 rises, it acts on the arc-shaped rubber pad 221, which in turn drives the arc-shaped placement frame 22 to rise. During the rise, the sliding shaft 222 on the side wall of the arc-shaped placement frame 22 moves along the trajectory of the inclined groove 23. The arc-shaped placement frame 22 slides at the upper limit of the limiting shaft 212. The arc-shaped placement frame 22 moves towards the side wall of the mounting frame 21 while rising, which in turn moves the plate frame 211 to apply force to the buffer spring 213. During the movement of the sliding shaft 222 in the inclined groove 23, the sliding shaft 222 applies force to the sensing element 231, indicating that needle assembly A3 is bent. To avoid the bent needle assembly A3 affecting the combing of the silk strips, the present invention replaces needle assembly A3 accordingly.

[0044] Step 3: When the connecting sleeve 41 rises to its end, that is, when the magnetic sleeve 8 on the connecting sleeve 41 contacts the magnetic sleeve 8 on the sliding frame 71, the needle assembly A3 is located inside the top comb plate frame 2. Then, the electromagnetic component 73 is energized, and the force-bearing magnetic plate 74 on one side of one of the sliding frames 71 will be subjected to a repulsive force. As a result, the two interconnected sliding frames 71 will adjust their positions within the fixed frame 7, and the sliding frames 71 will drive the corresponding connecting sleeve 41, needle assembly A3, and spare needle assembly B42 to adjust their positions through the guide shaft 72. That is, needle assembly A3 moves away from its original position, and spare needle assembly B42 moves to the needle assembly A3. The original position of group A3 is moved to achieve the purpose of replacing the bent needle group A3. The bent needle group A3 is located on one side of the fixed frame 7 so that it can be collected by the staff later. After the spare needle group B42 moves to the original position of needle group A3, the electric magnetic plate 20 is de-energized. The threaded shaft 10 moves to the initial position under the action of the constant force spring 9, that is, repeats the above action, but the rotation direction of the rotating sleeve 28 is opposite. The force-applying magnetic plate A61 returns to the initial position to generate a repulsive force on the magnetic surface at the top of the connecting sleeve 41. Then the spare needle group B42 replaces the needle group A3 to perform fine combing work on the silk strip.

[0045] A combing method for a silk strip dyeing and combing device specifically includes the following steps:

[0046] S1. During the combing process of the silk strips using the combing mechanism 1, multiple needle groups A3 on the top comb plate frame 2 comb the silk strips and periodically test the bending degree of the needle groups A3. During the test, the electric magnetic plate 20 is energized, generating a repulsive force on the annular magnetic plate 101. The threaded shaft 10 slides at the upper limit of the support shaft 25 and compresses the constant force spring 9. The rotating sleeve 28 rotates within the limiting sleeve 27 under the action of the rolling ball 281. The rotating sleeve 28 drives one of the pulleys 51 to rotate, and the pulley 51 drives another pulley 51 to rotate through the belt body 52. ​​Then the connecting plate frame 29 on it moves. The force-applying magnetic plate A61 located directly above the needle group A3 moves away, and the force-applying magnetic plate B62 is located directly above the needle group A3, that is, directly above the connecting sleeve 41. The force-applying magnetic plate B62 generates an attractive force on the connecting sleeve 41, and the connecting sleeve 41 drives the needle group A3 to move upward.

[0047] S2. During the upward movement of needle assembly A3, it is always in contact with the arc-shaped rubber pad 221. If needle assembly A3 bends, it will act on the arc-shaped rubber pad 221 during the upward movement. The arc-shaped rubber pad 221 and the arc-shaped placement frame 22 move synchronously upward. The sliding shaft 222 on the arc-shaped placement frame 22 moves along the trajectory of the inclined groove 23 and touches the sensing element 231 during the movement. This indicates that the needle assembly A3 is bent and needs to be replaced. During the movement of the sliding shaft 222 on the arc-shaped placement frame 22 along the trajectory of the inclined groove 23, the arc-shaped rubber pad 221 gradually separates from the needle assembly A3. When the connecting sleeve 41 rises to the end, that is, when the magnetic sleeve 8 on the connecting sleeve 41 contacts the magnetic sleeve 8 on the sliding frame 71, the needle assembly A3 is located inside the top comb plate frame 2.

[0048] S3. During the ascent, the suction pipe 24 sucks up the fibrous impurities on the surface of the needle assembly A3 to clean them.

[0049] S4. When the bent needle assembly A3 enters the top comb plate frame 2, the electromagnetic component 73 is energized to generate a repulsive force on the force-receiving magnetic plate 74 on one side of one of the sliding frames 71. The sliding frame 71 corresponding to the needle assembly A3 slides within the fixed frame 7, and the sliding frame 71 corresponding to the spare needle assembly B42 moves to the initial position of the sliding frame 71 corresponding to the needle assembly A3. At this time, the bent needle assembly A3 has been replaced, and the needle assembly B moves to the position directly below the force-receiving magnetic plate B62, while the needle assembly A3 is no longer directly below the force-receiving magnetic plate B62. Subsequently, the electric magnetic plate 20 is de-energized, and the threaded shaft 10 returns to its initial position under the action of the constant force spring 9, that is, the force-receiving magnetic plate A61 returns to its initial position, generating a repulsive force on the needle assembly B, so that the needle assembly B descends to the position for combing the silk strips, thereby achieving the purpose of replacing the bent combing needle assembly.
