AI Technical Summary
Existing yarn winding mechanisms used in yarn processing tend to concentrate the winding at the same position on the bobbin, forming protruding or ribbon-like yarn bundles. This results in low package strength, easy collapse and yarn tangling, and makes it difficult to unwind smoothly in subsequent processes such as warping and weaving.
The design employs a combination of sorting and reciprocating units. A rotary motor drives the turntable to rotate, and the linkage column slides in the linkage groove, causing the linkage rod to swing. The connecting column and guide rod realize the linear reciprocating movement of the yarn, ensuring orderly distribution and uniform winding of the yarn, and avoiding concentrated winding.
It improves the strength of yarn packages, prevents collapse and yarn tangling, ensures smooth unwinding in subsequent processes, and improves the orderliness and efficiency of yarn winding.

Description
Technical Field
[0001] This utility model relates to the field of yarn processing technology, specifically to a drafting and winding mechanism for yarn processing. Background Technology
[0002] The core function of the drafting mechanism is to uniformly lengthen and thin the fed roving or fiber sliver, while straightening and paralleling the fibers, thus providing a stable foundation for subsequent twisting.
[0003] According to the patent titled "Wool Yarn Drafting and Winding Device" (patent publication number: CN214193573U, patent publication date: 2021-09-14), it includes a fixed spinning assembly and a drafting assembly. The fixed spinning assembly includes spinning shafts erected vertically upwards, each of which can rotate synchronously. The drafting assembly includes a rail base, a traveling base mounted on the rail, a drive roller, a winding driven roller, and a pressing device. A roving is placed on the winding driven roller. The rotation of the drive roller drives the winding driven roller to rotate, realizing the yarn output from the roving. The other end of the yarn passes through the pressing device and is wound around the spinning shaft. The rotation of the spinning shaft realizes the winding action, and the movement of the traveling base on the rail base realizes the drafting action of the yarn. It can directly draft and twist the wool roving wound on the winding driven roller and directly spin it into wool yarn, achieving a high degree of automation, high processing efficiency, and good product consistency.
[0004] Based on the aforementioned existing technology, current drafting and winding mechanisms for yarn processing still have the following problems: existing drafting and winding mechanisms tend to concentrate the yarn at the same position on the bobbin, forming protruding or ribbon-like yarn bundles. These irregularly shaped bundles have low strength and are prone to collapsing and becoming tangled during handling and storage. Furthermore, they cannot be easily unwound in subsequent processes such as warping and weaving. Therefore, this utility model provides a drafting and winding mechanism for yarn processing.

[0016] 2. The yarn drafting and winding mechanism used in this yarn processing has a linkage column that slides in the linkage groove and a connecting column that slides in the U-shaped groove. This converts the rotational motion of the turntable into the oscillation of the linkage rod, which in turn drives the connecting column to move linearly, achieving precise reciprocating guidance and improving the orderliness and efficiency of yarn winding.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 This utility model provides a technical solution:
[0024] A yarn drafting and winding mechanism for yarn processing includes a drafting mechanism 1, a take-up assembly 3 at the top of the drafting mechanism 1, and a winding mechanism 2 at the top of the drafting mechanism 1 for achieving orderly yarn winding. The winding mechanism 2 includes:
[0025] The sorting unit 21 is located on the top of the drafting mechanism 1 and includes a base 211. A limiting track plate 212 is fixedly installed on the top of the base 211. A sliding block 213 is slidably installed inside the limiting track plate 212. A connecting column 214 is fixedly installed on the top of the sliding block 213. A guide rod 215 is fixedly installed on the top of the connecting column 214. The yarn passes through the round hole of the guide rod 215. The sliding block 213 is driven to move back and forth by the reciprocating unit 22, so as to realize the orderly winding of the yarn by the winding assembly 3.
[0026] The reciprocating unit 22 is disposed above the base 211 and is used to drive the sliding block 213 to reciprocate.
[0027] In this embodiment, the reciprocating unit 22 includes a turntable 221 rotatably mounted on the top of the base 211. A linkage column 222 is fixedly mounted on the top of the turntable 221 near the edge. The turntable 221 is driven to rotate by a rotary motor 226 at the bottom of the base 211.
[0028] The rotary motor 226 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and can be opened and closed through a human-operated control panel. Driven by the rotary motor 226, the linkage rod 223 swings, thereby driving the sliding block 213 to reciprocate within the limit track plate 212, realizing the linear reciprocating motion of the guide rod 215, ensuring that the yarn is evenly wound on the take-up drum 34, and avoiding yarn accumulation or irregular roll formation.
[0029] In this embodiment, a linkage rod 223 is rotatably mounted on the top of the base 211, and a linkage groove 224 is provided inside the linkage rod 223. The linkage column 222 slides inside the linkage groove 224. A U-shaped groove 225 is provided at one end of the linkage rod 223, and the connecting column 214 slides inside the U-shaped groove 225.
[0030] The linkage column 222 slides in the linkage groove 224, and the connecting column 214 slides in the U-shaped groove 225, converting the rotational motion of the turntable 221 into the swing of the linkage rod 223, which in turn drives the connecting column 214 to move linearly, achieving precise reciprocating guidance and improving the orderliness and efficiency of yarn winding.
[0031] In this embodiment, the drawing mechanism 1 includes a frame 11, a base 211 fixedly mounted on the top of a gear 111, a rotary motor 226 fixedly mounted on the bottom of the frame 11, and the output end of the rotary motor 226 passing through the frame 11 and the base 211 and fixedly connected to the bottom of the turntable 221. A mounting frame 12 is fixedly mounted on the top of the frame 11, and a first main roller 17, a second main roller 18, and a third main roller 19 are rotatably mounted inside the mounting frame 12. A secondary roller 110 is rotatably mounted above each of the first main roller 17, the second main roller 18, the second main roller 19, and the third main roller 19. Guide rollers 112 are rotatably mounted on the right side of the first main roller 17, the left and right sides of the secondary roller 110 above the second main roller 18, and the left side of the third main roller 19. Gears 111 are fixedly mounted on the front end surfaces of the first main roller 17, the second main roller 18, the third main roller 19, and the secondary roller 110. The gears 111 on the first main roller 17, the second main roller 18, and the third main roller 19 are meshed with the gears 111 on the secondary roller 110.
[0032] The first main roller 17, the second main roller 18, and the third main roller 19, along with the secondary roller 110, are supported by the frame 11 and the mounting frame 12. The gear 111 meshes and drives the rollers to rotate synchronously. The guide roller 112 guides the yarn path, achieving uniform drafting and straightening of the yarn, and providing a stable foundation for subsequent yarn winding.
[0033] In this embodiment, the rear end of the first main roller 17 passes through the frame 11 and is fixedly mounted with a first double-groove synchronous pulley 13; the rear end of the second main roller 18 passes through the frame 11 and is fixedly mounted with a second double-groove synchronous pulley 14; the rear end of the third main roller 19 passes through the frame 11 and is fixedly mounted with a first synchronous pulley 15; a base 113 is fixedly mounted on the rear side of the frame 11; a motor 114 is fixedly mounted on the top of the base 113; a second synchronous pulley 115 is fixedly mounted on the output end of the motor 114; the first synchronous pulley 15 and the second double-groove synchronous pulley 14, the second double-groove synchronous pulley 14 and the first double-groove synchronous pulley 13, and the second synchronous pulley 115 and the first double-groove synchronous pulley 13 are connected by a synchronous belt 16; and a guide rod 116 is fixedly mounted at the bottom of the inner cavity of the mounting frame 12.
[0034] Motor 114, model EDSMT-2T110-020A, is electrically connected to an external power supply and is operated by a human-controlled control panel. The first main roller 17, the second main roller 18, and the third main roller 19 are connected by the first double-groove synchronous pulley 13, the second double-groove synchronous pulley 14, and the first synchronous pulley 15, respectively. Motor 114 drives the second synchronous pulley 115 through the synchronous belt 16 to ensure that each roller rotates at a set speed. The guide rod 116 further guides the yarn, improving drafting stability and processing quality.
[0035] In this embodiment, the winding assembly 3 includes a fixed frame 31 fixedly installed on the top of the frame 11. A cylinder 32 is fixedly installed on the front side of the fixed frame 31, and the output end of the cylinder 32 passes through the fixed frame 31 and is rotatably mounted on a first clamping plate 33. A servo motor 36 is fixedly installed on the rear side of the fixed frame 31, and the output end of the servo motor 36 passes through the fixed frame 31 and is fixedly mounted on a second clamping plate 35. A winding drum 34 is installed between the second clamping plate 35 and the first clamping plate 33.
[0036] The servo motor 36, model SST43D2126, is electrically connected to an external power supply and is operated by a human control panel. The cylinder 32 and the servo motor 36 are supported by the fixed frame 31. The cylinder 32 pushes the first clamping plate 33 and the second clamping plate 35 to clamp the winding drum 34. The servo motor 36 drives the winding drum 34 to rotate, realizing the automatic winding of the yarn. It is easy to operate and has a firm clamping, ensuring a smooth and efficient winding process.
[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0038] During operation, firstly, the motor 114 drives the second synchronous pulley 115 to rotate. The second synchronous pulley 115 drives the first double-groove synchronous pulley 13 to rotate via the synchronous belt 16. The first double-groove synchronous pulley 13 drives the second double-groove synchronous pulley 14 to rotate via the synchronous belt 16. The second double-groove synchronous pulley 14 drives the first synchronous pulley 15 to rotate via the synchronous belt 16. The rotation of the first double-groove synchronous pulley 13, the second double-groove synchronous pulley 14, and the first synchronous pulley 15 drives the second main roller 18 and the third main roller 19 to rotate. The yarn is then directed by the guide roller 112 to pass between the first main roller 17, the second main roller 18, the third main roller 19, and the secondary roller 110.
[0039] Next, the take-up drum 34 is placed between the first clamping plate 33 and the second clamping plate 35. The cylinder 32 operates to push the first clamping plate 33 to clamp and fix the take-up drum 34. The yarn passes through the round hole of the guide rod 116 and the guide rod 215 and is wound around the surface of the take-up drum 34. The take-up assembly 3 operates to drive the second clamping plate 35 and the take-up drum 34 to rotate and wind the yarn.
[0040] Then, during the winding process, the rotary motor 226 runs, driving the turntable 221 to rotate. The rotation of the turntable 221 causes the linkage column 222 to slide inside the linkage groove 224, causing the linkage rod 223 to swing left and right in an arc. The linkage rod 223 drives the connecting column 214 to move back and forth in a straight line. The connecting column 214 drives the sliding block 213 to move back and forth inside the limit track plate 212. The connecting column 214 drives the guide rod 215 to move synchronously, so that the yarn is wound back and forth in an orderly manner on the winding drum 34.
