Description

Technical Field

[0001] This utility model relates to the field of polyester low-elasticity yarn production technology, specifically to a polyester low-elasticity yarn anti-knotting and winding roller. Background Technology

[0002] Polyester low-elasticity yarn is a type of textured yarn of polyester chemical fiber. It is mainly made from polyester chips, which are spun into pre-oriented polyester yarn at high speed and then processed by drawing and false twisting. Polyester low-elasticity yarn is an ideal raw material for knitting or weaving and is suitable for making various clothing fabrics, such as suits and shirts. After the production of polyester low-elasticity yarn is completed, it needs to be wound and wound using winding rollers. Anti-knotting is an important feature of winding rollers.

[0003] For example, Chinese patent CN218860055U, entitled "A Composite Fiber Winding Roller," includes a roller body, with positioning rods fixedly installed at both ends of the roller body, and support plates provided at both ends of the roller body. A circular through hole is opened on one side of the support plate, and the outer circular wall surface of the positioning rod is movably sleeved with the circular through hole; a cutting assembly is provided at both ends of the roller body for cutting excess composite fibers wound on the surface of the roller body; the cutting assembly includes two fixing rings, which are movably sleeved on the outer circular wall surfaces of the two positioning rods respectively, and one side of the fixing ring is fixedly installed with one side of the support plate; and a storage box is fixedly installed on the top surface of the fixing rings, with a connecting opening on one side of the inside of the storage box, and a cutting blade is provided inside the storage box.

[0004] While the existing technology can achieve the winding of polyester low-elasticity yarn, in actual use, on the one hand, the polyester yarn is prone to knotting during winding. Usually, when winding polyester yarn, the yarn will slip off the roller and become knotted, thus affecting the quality of polyester yarn production. On the other hand, it is not convenient to remove the polyester yarn. Usually, when the polyester yarn is finished winding and removed, it is necessary to disassemble and reassemble the entire fixing structure of the winding roller body, which reduces the production efficiency of polyester yarn. Therefore, it does not meet the current needs. In response, we propose a polyester low-elasticity yarn anti-knotting winding roller. Utility Model Content

[0005] The purpose of this invention is to provide a polyester low-elasticity yarn anti-knotting winding roller to solve the problems mentioned in the background art, such as the easy knotting of polyester yarn during winding and winding, and the inconvenience of removing polyester yarn.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyester low-elasticity yarn anti-knotting winding roller, including a drive shaft, a winding roller body is sleeved on the outside of the drive shaft, the winding roller body is fixedly connected to the drive shaft, and grooves are provided on the upper and lower sides of both sides inside the winding roller body. The grooves have an open structure. Limiting discs are sleeved on both sides outside the winding roller body. The limiting discs slide with the winding roller body. L-shaped connecting seats are fixedly provided at the upper and lower ends of the inner side of the limiting disc. One end of the L-shaped connecting seat extends into the interior of the groove, and the L-shaped connecting seat slides and limits the groove.

[0007] Preferably, the slide groove has a plurality of threaded holes inside, which are evenly distributed and communicate with the slide groove. The L-shaped connecting seat cross plate has a second through hole inside, which is a through structure. A first bolt is installed inside the second through hole, and one end of the first bolt extends through the second through hole into the threaded hole.

[0008] Preferably, support frames are provided on both sides of the outside of the drive shaft, the support frames are symmetrically distributed, a rotating cavity is provided at the top inside the support frame, the rotating cavity has an open structure, and the drive shaft passes through the rotating cavity and extends to the outside of the support frame.

[0009] Preferably, a rotating disk is sleeved outside the drive shaft in the rotating cavity, the rotating disk is fixedly connected to the drive shaft, and the rotating disk rotates in conjunction with the rotating cavity.

[0010] Preferably, the rotating cavity is provided with a pressing seat inside the upper end of the rotating disk, the pressing seat is slidably engaged with the rotating cavity, and the lower end of the pressing seat is in contact with the rotating disk.

[0011] Preferably, the front and rear ends of the extrusion seat and the support frame are provided with first through holes, the first through holes on the extrusion seat and the first through holes on the support frame are positioned correspondingly, a second bolt is provided on the outside of the support frame near the winding roller body, the second bolt extends through the first through hole to the other side of the support frame, and a nut is sleeved on the outside of the second bolt.

[0012] Preferably, the drive shaft has a connecting cavity inside one side of the support frame, and the connecting cavity has an open structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can limit the winding of polyester filament by using a limiting plate and a sliding groove. Before winding the polyester filament, the spacing of the limiting plate is adjusted according to the actual production needs. At this time, the operator pushes the limiting plate and moves the L-shaped connecting seat in the sliding groove until the limiting plate is adjusted to a suitable position. At this time, the second through hole on the L-shaped connecting seat corresponds to a certain threaded hole inside the sliding groove. Then, the first bolt is inserted into the second through hole and rotated so that the lower end of the first bolt enters the threaded hole, thus completing the fixing of the limiting plate and preventing the polyester filament from slipping off course during winding and winding, thereby reducing the risk of knotting when winding the polyester filament.

[0015] (2) This utility model allows for quick assembly and disassembly of the winding roller body via the extrusion seat and the second bolt. When the winding roller body needs to be removed, the operator first rotates the nut to disengage it from the second bolt. Then, the second bolt is pulled out from the support frame, and the extrusion seat is removed from the rotating cavity. Finally, the winding roller body and the drive shaft are removed from the support frame together, and the wound polyester yarn is processed. When installing the winding roller body, the drive shaft is aligned with the opening of the rotating cavity and moved downward until the drive shaft is moved to the appropriate position. At this time, the rotating disks on both sides of the drive shaft and the rotating cavity are limited to rotation. Then, the extrusion seat is placed into the rotating cavity and fixed by the second bolt and the nut, thereby improving the flexibility of assembling and disassembling the winding roller body.

[0016] (3) By providing a rotating disk, the present invention can limit the rotation of the drive shaft. When the polyester yarn is wound, the external drive mechanism drives the drive shaft to rotate. At this time, the rotating disk located outside the drive shaft rotates inside the rotating cavity. The rotating disk limits the rotation of the drive shaft, reduces the offset during the rotation of the drive shaft, and thus improves the stability of the drive shaft rotation.

[0024] Please see Figure 1 , Figure 2 and Figure 4 The winding roller body 2 has grooves 3 on both sides inside, and the grooves 3 have an open structure. Limiting disks 4 are sleeved on both sides outside the winding roller body 2. The limiting disks 4 slide with the winding roller body 2. L-shaped connecting seats 5 are fixedly installed at the upper and lower ends inside the limiting disks 4. One end of the L-shaped connecting seat 5 extends into the interior of the groove 3, and the L-shaped connecting seat 5 slides and limits the groove 3. The interior of the groove 3 has several threaded holes 13. The threaded holes 13 are evenly distributed and communicate with the groove 3. The interior of the horizontal plate of the L-shaped connecting seat 5 has a second through hole 16. The second through hole 16 has a through structure. The interior of the second through hole 16 has a first bolt 6. One end of the first bolt 6 extends through the second through hole 16 into the threaded hole 13, which facilitates the limiting of the polyester filament by the limiting disks 4.

[0025] Please see Figure 1 and Figure 2The rotating cavity 7 is located inside the upper end of the rotating disk 8 and is provided with an extrusion seat 10. The extrusion seat 10 is slidably engaged with the rotating cavity 7 and the lower end of the extrusion seat 10 is in contact with the rotating disk 8. The extrusion seat 10 and the support frame 14 are provided with first through holes 15 at their front and rear ends. The first through holes 15 on the extrusion seat 10 and the first through holes 15 on the support frame 14 are positioned correspondingly. A second bolt 11 is provided on the outside of the support frame 14 near the side of the winding roller body 2. The second bolt 11 extends through the first through hole 15 to the other side of the support frame 14. A nut 12 is sleeved on the outside of the second bolt 11 to facilitate quick assembly and disassembly of the winding roller body 2 through the extrusion seat 10 and the second bolt 11.

[0026] Please see Figure 1 and Figure 3 A rotating disk 8 is sleeved on the outside of the drive shaft 1 in the rotating cavity 7. The rotating disk 8 is fixedly connected to the drive shaft 1, and the rotating disk 8 is rotatably engaged with the rotating cavity 7, so as to facilitate the rotation limit of the drive shaft 1 through the rotating disk 8.

[0027] Working principle: In use, first adjust the spacing of the limit plate 4 according to the actual production needs. At this time, the operator pushes the limit plate 4 to move the L-shaped connecting seat 5 in the slide groove 3 until the limit plate 4 is adjusted to the appropriate position.

Then, insert the first bolt 6 into the second through hole 16 and rotate it so that the lower end of the first bolt 6 enters the threaded hole 13. When it is necessary to remove the winding roller body 2, the operator first rotates the nut 12 to disengage the nut 12 from the second bolt 11. At this time, the second bolt 11 is pulled out from the support frame 14, and then the extrusion seat 10 is removed from the rotating cavity 7. Remove the winding roller body 2 and drive shaft 1 from the support frame 14, and process the wound polyester yarn. When installing the winding roller body 2, align the drive shaft 1 with the opening of the rotating cavity 7 and move the drive shaft 1 downward until the drive shaft 1 is moved to the appropriate position. At this time, the rotating disks 8 on both sides of the drive shaft 1 and the rotating cavity 7 are limited to rotation. Then, put the extrusion seat 10 into the rotating cavity 7 and fix it with the second bolt 11 and nut 12. When winding the polyester yarn, the external drive mechanism drives the drive shaft 1 to rotate. At this time, the rotating disk 8 located outside the drive shaft 1 rotates inside the rotating cavity 7, and the rotating disk 8 limits the rotation of the drive shaft 1.
