Description

Technical Field

[0001] This utility model relates to the field of combing roller technology, and in particular to a combing roller structure for a cashmere combing machine. Background Technology

[0002] The carding roller is a basic component that combs and breaks down sliver into individual fibers, removes impurities, and transfers fibers to the fiber conveying channel. Therefore, in a sense, it has a significant impact on the quality of cashmere yarn, such as the evenness of the yarn and the amount of impurities in the yarn. It is generally required that the tips of the carding roller teeth be smooth and sharp, with high hardness and appropriate tooth shape and working angle, so as to penetrate deep into the cotton sliver, which is conducive to the carding, opening and removal of impurities of cotton fibers, and also conducive to the release and transfer of cotton fibers.

[0003] The existing cashmere combing machine's combing roller structure (publication number: CN221778039U) has at least the following drawbacks: This device passes the end of the metal needle cloth through to the outside of the end cap, and then uses multiple arc-shaped blocks to fix the metal needle cloth by applying pressure towards the outside of the end cap. However, since both ends of the metal needle cloth need to pass through to the outside of the end cap, when one end of the metal needle cloth passes through to the outside of the end cap, the entire metal needle cloth is already covered on the outer wall of the roller. At this time, a gap needs to be left between the metal needle cloth and the outer wall of the roller to ensure that the metal needle cloth can slide laterally, so that the other end of the metal needle cloth can also pass through to the outside of the end cap for fixation. This results in the metal needle cloth not being able to tightly cover the outer wall of the roller. Due to the relatively soft nature of the metal needle cloth, the combing needles on it become unstable and wobble slightly, thus affecting the combing effect. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cashmere combing machine combing roller structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cashmere combing machine combing roller structure includes a combing roller body, the outer wall of which is covered with metal needle cloth. The outer wall of the combing roller body is provided with an installation component for mounting the metal needle cloth. The installation component includes several positioning grooves formed on the outer wall of the combing roller body. Several positioning blocks are fixed inside the metal needle cloth. The positioning blocks are interference-fitted with the inside of the positioning grooves. Two pressure grooves are formed at both ends of the outer wall of the combing roller body. Two connecting plates are fixed at both ends of the metal needle cloth. A pressure block is fixed on one side of the connecting plate. The pressure block is interference-fitted with the pressure groove.

[0007] As a further embodiment of this utility model, the positioning block is a right-angled triangular structure, the positioning groove is adapted to the positioning block, the pressure block is a cuboid structure, and mounting blocks are provided at both ends of the top of the combing roller body. The mounting blocks are movably fitted inside the pressure groove, and the bottom end of the mounting block presses on the top surface of the pressure block.

[0008] As a further embodiment of this utility model, the right-angled edge of the positioning block is set along the counterclockwise rotation direction of the combing roller body.

[0009] As a further embodiment of this utility model, the top surface of the mounting block is provided with a countersunk hole, and a bolt is movably fitted inside the countersunk hole, with the bolt threadedly connected to the top surface inside the pressure groove.

[0010] As a further embodiment of this utility model, both ends of the top surface of the outer wall of the combing roller body are provided with fastening grooves.

[0011] As a further embodiment of this utility model, a keyway is provided on the inner wall of the combing roller body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By pulling the pressure block at one end of the metal needle cloth, it is pressed tightly into the inside of the pressure groove. Then, the other end of the metal needle cloth is pulled counterclockwise along the main body of the combing roller. Under the tension of the metal needle cloth, the positioning block is pressed tightly into the inside of the positioning groove by the cooperation of the inclined surface of the positioning block and the inclined surface of the positioning groove to position the metal needle cloth. Then, the pressure block at the other end of the metal needle cloth is pressed into the inside of the pressure groove to fix it. This ensures that the metal needle cloth is tightly wrapped around the outer wall of the main body of the combing roller, avoiding leaving any movable gaps, ensuring the stability of the metal needle cloth needles, and increasing the reliability of the device.

[0022] Reference Figures 1-4 A cashmere combing machine combing roller structure includes a combing roller body 1, the outer wall of which is covered with metal needle cloth 101. The outer wall of the combing roller body 1 is provided with an installation assembly for mounting the metal needle cloth 101. The installation assembly includes several positioning grooves 2 formed on the outer wall of the combing roller body 1. Several positioning blocks 201 are fixed inside the metal needle cloth 101. The positioning blocks 201 are interference-fitted with the inside of the positioning grooves 2. Two pressure grooves 202 are formed at both ends of the outer wall of the combing roller body 1. Two connecting plates 203 are fixed at both ends of the metal needle cloth 101. A pressure block 204 is fixed on one side of the connecting plate 203. The pressure block 204 is interference-fitted with the pressure groove 202.

[0023] Reference Figures 2-4In this embodiment, the positioning block 201 is a right-angled triangular structure, the positioning groove 2 is adapted to the positioning block 201, the pressure block 204 is a cuboid structure, and mounting blocks 205 are provided at both ends of the top of the combing roller body 1. The mounting blocks 205 are movably fitted inside the pressure groove 202, and the bottom end of the mounting block 205 presses against the top surface of the pressure block 204. By pulling the pressure block 204 at one end of the metal needle cloth 101, the pressure block 204 is pressed tightly into the interior of the pressure groove 202 by pressing the connecting plate 203. Then, the other end of the metal needle cloth 101 is pulled and pulled counterclockwise along the combing roller body 1, so that the positioning block 201 is in the metal needle cloth 101 The tension force, combined with the inclined surface of the positioning block 201 and the inclined surface of the positioning groove 2, tightly presses the metal needle cloth 101 into the interior of the positioning groove 2 to position it. Then, the pressing block 204 at the other end of the metal needle cloth 101 is pressed into the interior of the pressing groove 202 for fixation, thereby ensuring that the metal needle cloth 101 is tightly wrapped around the outer wall of the combing roller body 1. Then, the mounting block 205 is pressed into the interior of the pressing groove 202 and installed, thereby completing the installation of the metal needle cloth 101. This ensures that the metal needle cloth 101 is tightly wrapped around the outer wall of the combing roller body 1, avoiding leaving any movable gaps, ensuring the stability of the needle tip of the metal needle cloth 101, and increasing the reliability of the device.

[0024] Reference Figures 2-4 In this embodiment, the right-angled edge of the positioning block 201 is set along the counterclockwise rotation direction of the combing roller body 1. By setting the right-angled edge of the positioning block 201 along the counterclockwise rotation direction of the combing roller body 1, it is ensured that the right-angled edge of the positioning block 201 is subjected to force when the combing roller body 1 rotates, thus avoiding the inclined surface of the positioning block 201 being subjected to force. This would cause the inclined surface of the positioning block 201 to engage with the inclined surface of the positioning groove 2, resulting in a slight separation between the positioning block 201 and the positioning groove 2, which would lead to instability of the metal needle cloth 101 needle and affect the combing effect.

[0025] Reference Figures 2-4 In this embodiment, the top surface of the mounting block 205 is provided with a countersunk hole 3, and a bolt 301 is movably fitted inside the countersunk hole 3. The bolt 301 is threadedly connected to the top surface inside the pressure groove 202. By inserting the bolt 301 into the inside of the countersunk hole 3 and threadedly connecting it to the top surface inside the pressure groove 202, the mounting block 205 and the combing roller body 1 can be detachably installed.

[0026] Reference Figures 2-4 In this embodiment, both ends of the top surface of the outer wall of the combing roller body 1 are provided with buckle grooves 4. By disassembling the mounting block 205 and then snapping it into the inside of the buckle groove 4, the pressure block 204 can be removed from the inside of the pressure groove 202 and the metal needle cloth 101 can be disassembled.

[0027] Reference Figures 2-4In this embodiment, the inner wall of the combing roller body 1 is provided with a keyway 5. By setting the keyway 5, it is convenient to position and install the combing roller body 1 on the drive shaft of the combing machine.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when the metal needle cloth 101 needs to be installed on the outer wall of the combing roller body 1, pull the pressure block 204 at one end of the metal needle cloth 101. By pressing the connecting plate 203, the pressure block 204 is pressed tightly into the interior of the pressure groove 202. Then, pull the other end of the metal needle cloth 101 and pull it counterclockwise along the combing roller body 1. Under the tension of the metal needle cloth 101, the positioning block 201 is pressed tightly into the interior of the positioning groove 2 by the cooperation of the inclined surface of the positioning block 201 and the inclined surface of the positioning groove 2 to position the metal needle cloth 101. Then, the metal needle cloth 101 is installed on the outer wall of the combing roller body 1. 1. The pressure block 204 at the other end is pressed into the inside of the pressure groove 202 for fixation, thereby ensuring that the metal needle cloth 101 is tightly wrapped around the outer wall of the combing roller body 1. Then, the mounting block 205 is pressed into the inside of the pressure groove 202, and the mounting block 205 is fixed to the pressure groove 202 with bolts 301, thereby completing the installation of the metal needle cloth 101. This ensures that the metal needle cloth 101 is tightly wrapped around the outer wall of the combing roller body 1, avoiding leaving any movable gaps, ensuring the stability of the needle tip of the metal needle cloth 101, and increasing the reliability of the device. When disassembling, first remove the mounting block 205, and then snap it into the inside of the snapping groove 4 to remove the pressure block 204 from the inside of the pressure groove 202 and disassemble the metal needle cloth 101.
