Description

Technical Field

[0001] This utility model relates to the field of textile processing equipment technology, specifically to a yarn cutting and winding device. Background Technology

[0002] Yarn cutting and winding is a crucial process in textile production, and its quality directly affects the smooth operation of subsequent processes and the quality of the final product. In textile production, long yarns need to be cut and wound to specific lengths, requiring cutting and winding devices with stable and reliable mechanical structures to ensure neat cuts and uniform winding. In recent years, with the rapid development of the textile industry and the continuous expansion of yarn production scale, higher demands have been placed on the mechanical performance and operational efficiency of cutting and winding devices. Especially in large-scale continuous production, the structural stability and ease of operation of the device are particularly important.

[0003] Existing yarn cutting and winding devices typically employ a fixed cutter and pressure plate for cutting, and a winding mechanism consisting of a drive roller and a driven roller to wind up the yarn. For example, Chinese patent CN221070450U discloses a yarn cutting device including a bracket, a limiting component, a thickness measuring component, and a limit switch. A drum is rotatably connected to the bracket, and yarn is wound on the drum. The bracket is equipped with a back plate, and a blade holder is elastically hinged to the bracket. It can trigger the limiting component to unlock through the thickness measuring component, allowing the blade holder to quickly cut the yarn and avoid wear on the yarn during cutting.

[0004] However, the aforementioned yarn cutting device has the following shortcomings in practical applications: First, the single-blade cutter structure used in this device has obvious technical defects. Due to the strong flexibility and extensibility of yarn itself, it is difficult to completely cut the yarn by relying solely on the instantaneous impact force of the cutter. In actual applications, the cutter often only partially cuts the yarn, causing the incompletely broken yarn to be wound into the winding device, resulting in product scrap and rework. This incomplete cutting not only reduces production efficiency but also increases manual inspection and rework costs. At the same time, the incompletely cut yarn will cause uneven tension during the winding process, further affecting the quality of the finished product. In addition, the existing device is not reasonable in its structural layout, and the operation is inconvenient when changing the cutter, which greatly reduces the practicality of the device.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0010] Furthermore, to ensure the cutting blade is securely fixed between the snap-fit ​​block and the locking block, guaranteeing stability during the cutting process, the cutting mechanism includes a mounting frame positioned at the center of the top of the worktable.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model has a scientific and novel structure. Through the design of synchronous winding of two sets of yarns, it realizes efficient winding of yarns. The tension component, cutting mechanism and winding mechanism are set in sequence on the worktable to form a complete yarn processing production line. Because the cutting is thorough and the tension is uniform, the problem of product scrap caused by the incomplete cutting of yarn being wound up is avoided, which significantly improves the quality of finished products and production efficiency.

[0014] 2. By setting up a first tension component, a second tension component, and a cutting mechanism, the yarn tension can be controlled while cutting is performed. The tension component adopts a three-hole overlapping structure design to ensure that the yarn remains straight and is subject to uniform tension control. The cutting mechanism adopts a scissor-type cutting structure with mirrored upper and lower parts. Through cross-cutting action, it effectively overcomes the flexibility of the yarn and ensures that the yarn can be completely cut, solving the technical problem that traditional single-piece cutters cannot completely cut the yarn.

[0015] 3. By setting up a winding mechanism and a yarn limiting frame, stable yarn winding is achieved. The winding mechanism adopts a double-set symmetrical winding roller structure driven by a servo motor. Combined with the concentric double-hole guide structure formed by the L-shaped clamping plate and the take-up drum in the yarn limiting frame, it effectively prevents the yarn from deviating and shaking during the winding process.

[0028] According to an embodiment of the present invention, a yarn cutting and winding device is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-8 As shown, the yarn cutting and winding device according to an embodiment of the present invention includes a workbench 1, a first tension component 2 is provided on one side of the top end of the workbench 1, a second tension component 3 is provided on the other side of the top end of the workbench 1, a cutting mechanism 4 is provided in the middle of the top of the workbench 1, a support block 5 is provided at the other end of the top of the workbench 1, a winding mechanism 6 is provided at one end of the top of the support block 5, and a yarn limiting frame 7 cooperating with the winding mechanism 6 is symmetrically provided at the other end of the top of the support block 5, and the first tension component 2 and the second tension component 3 have the same structure.

[0030] In addition, in specific applications, a control panel 9 is provided on one side of the workbench 1. The cylinder 402 and the drive motor 604 are electrically connected to each other through the control panel. This is existing technology and will not be elaborated on further here.

[0031] This utility model has a scientific and novel structure. It can achieve efficient yarn winding through the design of synchronous winding of two sets of yarns 8. The first tension component 2, the second tension component 3, the cutting mechanism 4 and the winding mechanism 6 are arranged in sequence on the workbench 1 to form a complete yarn processing production line. The cutting is thorough and the tension is uniform, avoiding the product scrap problem caused by the incomplete cutting of yarn being wound in, and significantly improving the quality of finished products and production efficiency.

[0032] In one embodiment, the first tension assembly 2 includes a mountain-shaped bracket 201 disposed at one end of the top of the workbench 1. Horizontal mounting plates 202 are disposed on both sides of the top of the mountain-shaped bracket 201, and a mounting plate 203 is disposed at the bottom of the horizontal mounting plates 202. A first U-shaped support 204 is disposed at the top of the horizontal mounting plates 202, and first thread pulleys 205 are symmetrically disposed on the inner side of the first U-shaped support 204. A first top plate 206 cooperating with the first thread pulleys 205 is disposed at the top of the first U-shaped support 204. A second U-shaped support 207 is disposed at the top of one side of the mountain-shaped bracket 201, and second thread pulleys 208 are symmetrically disposed on the inner side of the second U-shaped support 207. A second top plate 206 cooperating with the second thread pulleys 208 is disposed at one end of the second U-shaped support 207. Plate 209; and the first U-shaped support 204 and the second U-shaped support 207 have the same structure, the first spool 205 and the second spool 208 have the same structure, and the first top plate 206 and the second top plate 209 have the same structure; the first spool 205 includes a wheel axle 2051 that passes through the first U-shaped support 204 and the first top plate 206 (in addition, in specific applications, the two ends of the wheel axle 2051 are connected to the first U-shaped support 204 and the first top plate 206 respectively through bearings), a guide wheel disk 2052 is sleeved on the outer side of the middle part of the wheel axle 2051, an annular wheel axle sleeve 2053 is provided at the bottom of the guide wheel disk 2052, and an arc-shaped yarn guide groove 2054 is opened on the outer edge of the guide wheel disk 2052, so that the yarn 8 moves smoothly along the gap between the two sets of arc-shaped yarn guide grooves 2054, ensuring uniform tension distribution.

[0033] A first perforated gap is formed between the two sets of first yarn pulleys 205 within the first U-shaped support 204, and a second perforated gap is formed between the two sets of second yarn pulleys 208 within the second U-shaped support 207. The first perforated gap and the second perforated gap are arranged to coincide in the horizontal direction, thereby forming a straight transmission channel for yarn.

[0034] The working principle of the first tension assembly 2 is as follows: After the yarn 8 is introduced from the outside, it first passes through the first perforated gap formed between the two sets of first yarn wheels 205 in the first U-shaped support 204, then through the second perforated gap formed between the two sets of second yarn wheels 208 in the second U-shaped support 207, and finally through the first perforated gap in another set of first U-shaped supports. Since these perforated gaps coincide in the horizontal direction, a straight transmission channel is formed, allowing the yarn to maintain a straight running state. During the transmission process, the yarn generates moderate contact friction with the guide wheel discs 2052 of each set of yarn wheels. The support of the annular wheel bushing 2053 ensures that each disc rotates smoothly. When the yarn passes through this three-hole overlapping structure, the uniform friction force generated by multi-point contact can effectively prevent the yarn from becoming too loose or too tight, achieving precise control of the yarn tension and providing stable yarn conveying conditions for subsequent cutting and winding processes.

[0035] The first tension component 2 and the second tension component 3 have the same structure and the same working principle.

[0036] In one embodiment, the cutting mechanism 4 includes a mounting frame 401 located at the top center of the workbench 1. A cylinder 402 is mounted at the top of the mounting frame 401. A movable top plate 403 is mounted through the mounting frame 401 at the output end of the cylinder 402. Limiting rods 404 are mounted through both sides of the movable top plate 403. A fixed base plate 405 is mounted at the bottom end of the limiting rods 404. A first T-shaped strip 406 is mounted at the bottom end of the movable top plate 403. First cutting components 407 are mounted at both ends of the first T-shaped strip 406. A second T-shaped strip 408 is mounted at the top of the fixed base plate 405. Second cutting components 409 are mounted at both ends of the second T-shaped strip 408. A collision prevention post 410 is mounted at the center of the top of the second T-shaped strip 408. The T-shaped strip 406 and the second T-shaped strip 408 have the same structure, and the first cutting component 407 and the second cutting component 409 have the same structure. The first cutting component 407 includes a snap-fit ​​block 4071 disposed at one end of the first T-shaped strip 406. The top of the snap-fit ​​block 4071 is provided with a T-shaped snap-fit ​​groove 4072 that cooperates with the first T-shaped strip 406. A locking block 4073 is provided at the bottom of one side of the snap-fit ​​block 4071 (in addition, in specific applications, the snap-fit ​​block 4071 and the locking block 4073 are connected by bolts). The bottom ends of the snap-fit ​​block 4071 and the locking block 4073 are connected by a cutting blade 4074, so that the cutting blade 4074 can be firmly fixed between the snap-fit ​​block 4071 and the locking block 4073, ensuring stability during the cutting process.

[0037] The first cutting component 407 and the second cutting component 409 are mirror images of each other, so that the first cutting component 407 and the second cutting component 409 form a cross-cooperation scissor-type cutting structure during the descent process; the bottom of the snap-fit ​​block 4071 is provided with a first rectangular groove, and the bottom of the locking block 4073 is provided with a second rectangular groove. The first rectangular groove and the second rectangular groove cooperate to form a rectangular through hole for accommodating the cutting blade 4074, and the snap-fit ​​block 4071 and the locking block 4073 are fixedly connected by bolts to clamp and fix the cutting blade 4074.

[0038] The working principle of the cutting mechanism 4 is as follows: the two sets of yarns 8 enter the cutting mechanism 4 after passing through the first tension component 2 and the second tension component 3 respectively. When the yarns 8 need to be cut, the cylinder 402 starts to work under the control of the electrical signal of the control panel 9. The output end of the cylinder 402 drives the movable top plate 403 to move downward. The movable top plate 403 is kept vertically descending by the limit rods 404 on both sides. At the same time, the first T-shaped strip 406 at the bottom of the top plate drives the first cutting components 407 at both ends to move downward. During the descent, the cutting blade 4074 of the first cutting component 407 forms a scissor-like cross-cut with the second cutting components 409 at both ends of the second T-shaped strip 408 on the fixed base plate 405, and completely cuts the two sets of yarns 8.

[0039] The anti-collision post 410 at the top center of the second T-shaped strip 408 prevents the movable top plate 403 from descending excessively, causing the cutting blades 4074 to collide and be damaged, thus playing a limiting protection role. After the two sets of yarns are cut simultaneously, the cylinder 402 controls the movable top plate 403 to reset, driving the first cutting component 407 to rise, completing one double-thread synchronous cutting cycle. This design of synchronous cutting of double-thread yarns not only improves work efficiency but also ensures the consistency of cutting the two sets of yarns 8.

[0040] In one embodiment, for the aforementioned winding mechanism 6 and yarn limiting frame 7, the winding mechanism 6 includes a U-shaped bracket 601 symmetrically arranged at one end of the top of the support block 5. A winding roller 602 is provided on the inner top of the U-shaped bracket 601. A drive shaft 603 is provided through the middle of the two sets of winding rollers 602 and passes through the U-shaped bracket 601 (in addition, in practical applications, the two ends of the drive shaft 603 are connected to the U-shaped bracket 601 through bearings). A drive motor 604 is provided at one end of the drive shaft 603 (in addition, in specific applications, the drive motor 604 is set as a servo motor, and the output end of the drive motor 604 is fixedly connected to the drive shaft 603 through a coupling). The yarn limiting frame 7 includes an L-shaped snap-fit ​​plate 701 symmetrically arranged at the top of the support block 5. A take-up drum 702 is provided in the middle of the L-shaped snap-fit ​​plate 701, so that the take-up drum 702 can limit and guide the yarn, and cooperate with the winding roller 602 to achieve orderly winding of the yarn.

[0041] It should be noted that, in specific applications, the L-shaped card plate 701 has a first circular through hole in the middle of one side, and the take-up tube 702 has a second circular through hole in the middle of one side. The first circular through hole and the second circular through hole are concentric, and the diameter of the first circular through hole is larger than the diameter of the second circular through hole.

[0042] In practical applications, before winding, the two sets of yarns 8 first pass through the first tension component 2 and the second tension component 3, then through the cutting mechanism 4 and the yarn limiting frame 7, and are wound onto the winding rollers 602 on both sides of the winding mechanism 6. The operator can use tape to fix the ends of the yarns onto the winding rollers 602 to complete the initial setup.

[0043] The working principle of the winding mechanism 6 and the yarn limiting frame 7 is as follows: After the initial setup is completed, the drive motor 604 drives the winding roller 602 to rotate synchronously through the drive shaft 603 to start winding. The two sets of yarns 8 are guided by the take-up drum 702 on the corresponding L-shaped retaining plate 701. Since the first circular through hole of the L-shaped retaining plate 701 and the second circular through hole of the take-up drum 702 are concentric and have different diameters, a guide structure from large to small is formed, which allows the yarn to pass smoothly through the larger first circular through hole and then be precisely positioned through the smaller second circular through hole, effectively preventing the yarn from shifting or shaking during the winding process.

[0044] The symmetrical arrangement of the two sets of U-shaped brackets 601 ensures the synchronization of the winding of the two sets of yarns, while the double-hole guide structure of the L-shaped snap plate 701 and the take-up spool 702 ensures a more stable position during yarn winding. After the yarn reaches the predetermined thickness, the operator activates the cylinder 402 to cut it using the cutting mechanism 4, and then turns off the drive motor 604 to complete the winding operation of the two sets of yarns 8.

[0045] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0046] In practical applications, the operator first introduces the two sets of yarns 8 into the first tension assembly 2 and the second tension assembly 3, respectively. The yarns 8 pass sequentially through three perforated gaps within the tension assemblies (the first perforated gap within the first U-shaped support 204, the second perforated gap within the second U-shaped support 207, and the first perforated gap within another set of first U-shaped supports). Since these perforated gaps overlap in the horizontal direction, they form a straight transmission channel, keeping the yarns 8 running straight. At the same time, the multi-point contact with the guide wheel 2052 generates uniform friction, achieving precise tension control.

[0047] Subsequently, the two sets of yarns 8 pass through the working area of ​​the cutting mechanism 4. At this stage, the operator needs to pass the yarns 8 sequentially through the first circular through-hole of the L-shaped retaining plate 701 and the second circular through-hole of the take-up spool 702. Since the two through-holes are concentric and have different diameters, a guide structure from large to small is formed, ensuring that the yarns 8 can stably pass through the guide system. Next, the operator winds the yarns 8 onto the winding rollers 602 on both sides of the take-up mechanism 6 and secures the yarn ends with tape, completing the initial setup.

[0048] After starting the equipment, the drive motor 604 drives the two sets of winding rollers 602 to rotate synchronously via the drive shaft 603 to begin winding. When the yarn 8 reaches the predetermined thickness, the operator activates the cylinder 402 via the control panel 9, causing the movable top plate 403 to move downwards. At this time, the cutting blade 4074 of the first cutting component 407 and the cutting blade of the second cutting component 409 form a scissor-like cross-cutting motion, simultaneously cutting both sets of yarn 8. Due to the mirrored double-blade cross-cutting structure, even highly flexible yarns can be completely cut. After cutting, the operator turns off the drive motor 604, removes the wound yarn, and repeats the above operation for the next round of winding.

[0049] Throughout the process, the anti-collision posts 410 continuously provide limiting protection, preventing the cutting blades 4074 from colliding and being damaged. Meanwhile, the speed of the drive motor 604 can be adjusted at any time via the control panel 9, achieving precise control of the winding speed to meet the winding requirements of yarns of different specifications.
