Description

Technical Field

[0001] This utility model relates to the field of friction spinning technology, specifically a friction spinning device for parallel strand composite spinning. Background Technology

[0002] By combining multiple yarns (or filaments) in a parallel arrangement to form composite yarns with special structures or functions, and using friction spinning technology (such as DREF spinning) mechanical equipment, the fibers are polymerized and twisted into yarn by the mechanical action of friction rollers.

[0003] An existing patent (authorization announcement number: CN222348379U) discloses a textile thread surface treatment mechanism for a textile winding machine. The key technical point of the solution is that, through the cooperation of a motor, a winding shaft and a cleaning box, the textile thread surface treatment device of the textile winding machine can quickly wind up the surface-treated textile thread during use, which solves the problem of the textile thread being torn due to the inconvenience of accurately controlling the applied force during manual processing, thereby improving the work efficiency of textile thread surface treatment.

[0004] However, the above technical solutions still have certain defects. When the surface of the textile yarn is treated, it is impossible to evenly disperse the textile yarn surface and clean the textile yarn. As a result, when the textile yarn is wound up later, it is easy for the textile yarn to mix with other impurities, causing uneven surface tension and breakage. Therefore, a friction spinning device for parallel strand composite spinning is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a friction spinning device for parallel strand composite spinning to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A friction spinning apparatus for parallel strand composite spinning includes a frame, on which are sequentially arranged: an unwinding assembly including a support plate, a drive cylinder, and an unwinding roller; the drive cylinder is mounted on the side of the support plate, and its output end is fixedly connected to the unwinding roller; a combing roller rotatably mounted in the middle of the frame; a cleaning assembly including an air pump, an air jet pipe, a first motor, and a separating roller; the air jet pipe's air jet direction is towards the separating roller; the output end of the first motor is fixedly mounted on the end of the separating roller, and the first motor is fixedly mounted on one side of the support plate; and a spinning friction assembly located at the bottom of the frame, and a winding assembly is also provided at the bottom of the frame.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] As a further embodiment of this utility model: the abrasive spinning assembly includes a fixed plate fixedly installed at the bottom of the frame, a second motor fixedly installed on one side of the fixed plate, and a first friction roller and a second friction roller rotatably installed on one side of the fixed plate.

[0010] As a further embodiment of this utility model: the winding assembly includes a first transmission rod rotatably mounted on one side of a fixed plate, a first gear fixedly mounted on the other end of the transmission rod, and the first gear meshing with a second gear, the second gear being fixedly connected to a winding roller, a plurality of partition plates being fixedly mounted on the winding roller, and tapered columns being mounted on both ends of the winding roller respectively.

[0011] As a further embodiment of this utility model: the driving gear at the output end of the second motor; and the driven gears at the ends of the first and second friction rollers are synchronously driven by a belt.

[0013] As a further improvement of this invention, the axis of the hole in the jet pipe is tangent to the surface of the separating roller.

[0014] As a further improvement of this utility model, threaded grooves are provided on the surfaces of both the first friction roller and the second friction roller.

[0015] As a further improvement of this utility model, the take-up roller is made of nylon material.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, by setting up a cleaning component, allows the yarn blown apart by airflow to undergo initial separation by a separating roller. When the yarn surface is blown up, it passes through the separating roller, which helps the yarn to separate better and prevents the yarn from breaking due to forced separation when the yarn is stationary. At the same time, it can blow away other impurities on the yarn and clean the yarn.

[0018] 2. This utility model uses a spinning assembly to form an entangling structure by opening threaded grooves on the surfaces of the first and second friction rollers in a parallel state. At the same time, the threaded grooves increase the roughness of the friction roller surface, so that the yarn is subjected to a stronger gripping force when moving between the rollers, enhancing the radial wrapping force on the parallel fibers and preventing the yarn from slipping off.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-5 As shown, a friction spinning device for parallel strand composite spinning includes a frame 1, an unwinding assembly 2 including a support plate 21, a drive cylinder 22 and an unwinding roller 23, the drive cylinder 22 being installed on the side of the support plate 21 and the output end of the drive cylinder 22 being fixedly connected to the unwinding roller 23, a combing roller 4 being rotatably installed in the middle of the frame 1, a cleaning assembly 3, a spinning abrasion assembly 5, and a winding assembly 6 being provided at the bottom of the frame 1.

[0031] In this embodiment, the drive cylinder 22 is installed laterally and directly links with the unwind roller 23. The drive cylinder 22 dynamically adjusts the position of the unwind roller 23 according to the yarn tension feedback, and adjusts the yarn tension in real time. At the same time, the combing roller 4 opens the fiber bundle into a single fiber state to ensure subsequent parallel compounding. The yarn is cleaned and then frictionally retwisted after cleaning. Finally, the yarn is wound up to complete the friction spinning operation.

[0032] In one embodiment, such as Figure 2As shown, the cleaning component 3 includes an air pump 31, an air jet pipe 32, a first motor 33, and a separating roller 34. The air jet direction of the air jet pipe 32 is towards the separating roller 34, and the axis of the hole of the air jet pipe 32 is tangential to the surface of the separating roller 34. The output end of the first motor 33 is fixedly installed at the end of the separating roller 34, and the first motor 33 is fixedly installed on one side of the support plate 21. The tangential airflow generates shearing force, which can remove impurities from the fiber surface. The airflow direction is parallel to the fiber direction to avoid fiber disorder. At this time, the first motor 33 controls the separating roller 34 to rotate. The yarn blown apart by the airflow passes through the separating roller 34 for initial separation, so that the yarn surface passes through the separating roller 34 when it is blown up, which helps the yarn to be separated better and prevents the yarn from breaking due to forced separation in a static state. After the initial separation, the yarn passes through the combing roller 4 to improve the efficiency of yarn separation.

[0033] In one embodiment, such as Figure 3 As shown, the spinning assembly 5 is located at the bottom of the frame 1 and includes a first friction roller 53 and a second friction roller 54. The spinning assembly 5 includes a fixed plate 51 fixedly installed at the bottom of the frame 1, a second motor 52 fixedly installed on one side of the fixed plate 51, and the first friction roller 53 and the second friction roller 54 rotatably installed on one side of the fixed plate 51. The output end of the second motor 52 has a drive gear, and the driven gears at the ends of the first friction roller 53 and the second friction roller 54 are synchronously driven by a belt. The surfaces of the first friction roller 53 and the second friction roller 54 are both provided with threaded grooves. By starting the second motor 52, the first friction roller 53 and the second friction roller 54 are driven to rotate in the same direction, and the separated yarn is frictionally twisted. The high-speed rotating friction roller (made of rubber) applies frictional force to the fiber bundle, so that it forms an entangling structure in a parallel state. At the same time, the threaded groove increases the roughness of the friction roller surface, so that the yarn is subjected to a stronger gripping force when moving between the rollers, improving the spinning efficiency. At the same time, the spiral direction of the threaded groove can guide the material to move evenly along the roller axis, enhancing the radial wrapping force on the parallel fibers.

[0034] In addition, because the two sets of friction rollers rotate in opposite directions, the relative rotation creates shear force, which can improve the fineness of the spinning process.

[0035] In one embodiment, such as Figure 4 and Figure 5As shown, the winding assembly 6 includes a first transmission rod 61 rotatably mounted on one side of the fixed plate 51. A first gear 62 is fixedly mounted on the other end of the transmission rod 61, and the first gear 62 meshes with a second gear 63. The second gear 63 is fixedly connected to a winding roller 64. Multiple sets of partition plates 65 are fixedly mounted on the winding roller 64. Conical columns 66 are respectively mounted on both ends of the winding roller 64. Multiple sets of holes are formed on the surface of the winding roller 64. The winding roller 64 is made of nylon material. The first transmission rod 61 is driven to rotate by a second motor 52 via belt drive. The first transmission rod 61 drives the second gear 63 to rotate via the first gear 62, causing the take-up roller 64 to rotate and wind up the yarn. The separator plate 65 divides the surface of the take-up roller 64 into multiple independent areas, allowing multiple strands of yarn to be wound up simultaneously, preventing the yarns from tangling during the winding process. The inclined surface of the tapered column 66 guides the material to be evenly distributed along the axial direction of the take-up roller 64, preventing the material edges from shifting or piling up, and ensuring that the end face of the roll is neat. After winding is completed, the tapered column 66 can assist the roll to be quickly removed from the roller body. At the same time, the holes on the take-up roller 64 can reduce the contact area between the yarn and the take-up roller 64, avoiding friction damage.

[0036] The above embodiments disclose a friction spinning device for parallel ply composite spinning. In this device, a drive cylinder 22 is installed laterally and directly links to the unwind roller 23. The drive cylinder 22 dynamically adjusts the position of the unwind roller 23 according to the yarn tension feedback, thereby adjusting the yarn tension in real time. At the same time, the combing roller 4 opens the fiber bundle into a single fiber state to ensure subsequent parallel composite spinning. The yarn is cleaned and then frictionally retwisted after cleaning. Finally, the yarn is wound up.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
