Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a device for coating polyester and spandex yarns. Background Technology

[0002] Spandex filament, also known as spandex fiber, is short for polyurethane fiber. It is polymerized from PTMEG and MDI and is a material used in the modern apparel industry. However, existing spandex filaments are prone to tangling during production, which affects the production effect. When winding spandex filaments, excessive tension can easily lead to filament breakage and weft skew, affecting the production quality of spandex filaments. Furthermore, friction can easily occur between the spandex filaments and the winding rollers, damaging the spandex filaments.

[0003] For example, patent CN207552570U discloses a spandex covered yarn weaving device, including a yarn storage box, a weaving machine, and a support frame. The weaving machine is located below the yarn storage box, and the support frame is fixedly connected to both sides of the yarn storage box and is also fixedly connected to the weaving machine. A winding cylinder is fixedly installed at the top of the yarn storage box, and a guide roller is fixedly connected to the bottom of the winding cylinder. The guide roller is located at one end of the weaving machine, and an upper pressure roller is fixedly installed at the top of the weaving machine. This aforementioned spandex covered yarn weaving device has shortcomings. Although it achieves the covering of both filaments and core yarns, it has limitations. There is no tension adjustment mechanism before covering, which can easily lead to the yarn becoming loose or overly tight during weaving, thus affecting the uniformity and strength of the fabric.

[0004] Therefore, in order to solve such problems, we propose a polyester-spandex covered yarn covering device. Utility Model Content

[0005] The purpose of this invention is to provide a polyester-spandex covered yarn covering device, which aims to solve the problem in the above-mentioned background art that the existing spandex covered yarn weaving device is prone to yarn loosening or excessive tension during the weaving process due to the lack of a tension adjustment mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polyester / spandex covered yarn covering device, comprising a base, wherein two sets of tension adjusting components are provided on the upper end of the base, the tension adjusting components comprising two second mounting plates vertically arranged along the Z-axis, the lower end of one second mounting plate being fixedly connected to the base, a first mounting column being fixedly connected between the two second mounting plates, a second mounting column being fixedly connected to the side wall of the first mounting column, a third mounting column being slidably connected to the side wall of the first mounting column, the third mounting column being located at the lower end of the second mounting column, a first roller being fixedly connected to the side wall of the second mounting column, a second roller being fixedly connected to the side wall of the third mounting column, adjusting seats being fixedly connected to the side walls at both ends of the third mounting column, the adjusting seats being slidably connected to the side walls of the first mounting column, and a limiting plate being fixedly connected to the side wall of the first mounting column, the limiting plate being located between the second and third mounting columns.

[0007] Preferably, the adjusting seat has a first mounting groove on each of its two side walls, a second mounting groove on the inner side wall of the first mounting groove, a first spring fixedly connected to the inner wall of the second mounting groove, a baffle fixedly connected to one end of the first spring, the baffle being slidably connected to the inner wall of the second mounting groove, a placement rod fixedly connected to the inner wall of the first mounting groove, and a counterweight block engaging with the side wall of the placement rod.

[0008] Preferably, a mounting bracket is fixedly connected to the upper end of the base, and a covering yarn machine body is fixedly mounted on the upper end of the mounting bracket. A first yarn inlet is provided on the side wall of the covering yarn machine body, and a second yarn inlet is provided on the side wall of the covering yarn machine body. The first yarn inlet and the second yarn inlet are located on the same side wall of the covering yarn machine body. A yarn outlet is provided on the side wall of the covering yarn machine body away from the first yarn inlet. A connecting plate is fixedly connected to the side wall of the mounting bracket away from the yarn outlet. A support plate is fixedly connected to the upper end of the connecting plate. A first through hole and a second through hole are provided on the side wall of the upper end of the support plate.

[0009] Preferably, the first through hole and the first wire inlet are located in the same horizontal plane, the second through hole and the second wire inlet are located in the same horizontal plane, and both the first through hole and the second through hole have rounded corners at their ends.

[0010] Preferably, the counterweight is hook-shaped.

[0011] Preferably, both the second mounting groove and the baffle are T-shaped.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, by setting a first roller and a second roller, the device can achieve precise tension control of the filament and core yarn. When the yarn becomes slack, the second roller moves downward along the first mounting post to automatically increase the tension. When the yarn is taut, the second roller moves upward to release some of the tension. Its adaptive tension adjustment mechanism ensures the stability and consistency of the yarn during the covering process, reducing the occurrence of quality problems such as yarn breakage, wrinkles, and uneven thickness, thereby significantly improving the overall quality and performance of the covered yarn. Secondly, the design of the counterweight on the adjusting seat enables flexible adjustment of the tension. Users can change the tension of the second roller on the yarn by increasing or decreasing the weight of the counterweight according to actual needs, thereby meeting the needs of different production scenarios.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Reference Figure 1-5 This utility model provides an embodiment of a polyester-spandex covered yarn covering device, including a base 1. Two sets of tension adjusting components 2 are provided on the upper end of the base 1. Each tension adjusting component 2 includes two second mounting plates 21 vertically arranged along the Z-axis. The lower end of one second mounting plate 21 is fixedly connected to the base 1. A first mounting post 211 is fixedly connected between the two second mounting plates 21. A second mounting post 22 is fixedly connected to the side wall of the first mounting post 211. A third mounting post 221 is slidably connected to the side wall of the first mounting post 211, located at the lower end of the second mounting post 22. A first roller 23 is fixedly connected to the side wall of the second mounting post 22, and a second roller 24 is fixedly connected to the side wall of the third mounting post 221. Adjusting seats 25 are fixedly connected to the side walls at both ends of the third mounting post 221, and the adjusting seats 25 are slidably connected to the side walls of the first mounting post 211. A limiting plate 26 is fixedly connected to the side wall of the first mounting post 211, located between the second mounting post 22 and the third mounting post 221.

[0024] This setup winds the filament and core yarn around the sidewalls of the first roller 23 and the second roller 24 within two sets of tension adjustment components 2, respectively. When the filament or core yarn becomes slack, the second roller 24 moves downward along the first mounting post 211, thereby tensioning the filament or core yarn. When the filament or core yarn becomes taut, the second roller 24 moves upward along the first mounting post 211, thereby restoring the slack state of the filament or core yarn. This prevents the filament or core yarn from being damaged due to excessive tension, achieving tension adjustment and improving the quality and tension of the covered yarn to ensure the consistency of yarn winding.

[0025] The adjusting seat 25 has a first mounting groove 251 on both side walls and a second mounting groove 252 on the inner side wall of the first mounting groove 251. A first spring 253 is fixedly connected to the inner wall of the second mounting groove 252. A baffle 254 is fixedly connected to one end of the first spring 253. The baffle 254 is slidably connected to the inner wall of the second mounting groove 252. A placement rod 255 is fixedly connected to the inner wall of the first mounting groove 251. A counterweight 256 is engaged with the side wall of the placement rod 255. The counterweight 256 is used to utilize the elastic force of the first spring 253 to push the baffle 254 away from the first spring 253 and slide it out of the second mounting groove 252, thereby limiting the counterweight 256 and increasing stability. The counterweight 256 is also used to adjust the overall weight of the adjusting seat 25, thereby adjusting the tension.

[0026] A mounting bracket 11 is fixedly connected to the upper end of the base 1. A covering yarn machine body 3 is fixedly mounted on the upper end of the mounting bracket 11. A first yarn inlet 31 and a second yarn inlet 32 ​​are provided on the side wall of the covering yarn machine body 3. The first yarn inlet 31 and the second yarn inlet 32 ​​are located on the same side wall of the covering yarn machine body 3. A yarn outlet 33 is provided on the side wall of the covering yarn machine body 3 away from the first yarn inlet 31. A connecting plate 12 is fixedly connected to the side wall of the mounting bracket 11 away from the yarn outlet 33. A support plate 13 is fixedly connected to the upper end of the connecting plate 12. A first through hole 131 and a second through hole 132 are provided on the side wall of the upper end of the support plate 13. The core yarn is fed into the first yarn inlet 31 after passing through the first through hole 131, and the filament is fed into the second yarn inlet 32 ​​after passing through the second through hole 132. After being covered by the covering yarn machine body 3, the filament is discharged from the yarn outlet 33.

[0027] The first through hole 131 and the first inlet 31 are located in the same horizontal plane, and the second through hole 132 and the second inlet 32 ​​are located in the same horizontal plane. Both the first through hole 131 and the second through hole 132 have rounded corners at their ends to reduce wear on the core yarn and filament and increase the covering quality.

[0028] The counterweight 256 is hook-shaped and is used for engaging and connecting the counterweight 256 and the placement rod 255.

[0029] Both the second mounting groove 252 and the baffle 254 are T-shaped, which is used to limit the baffle 254 and prevent the baffle 254 from sliding directly out of the second mounting groove 252.

[0030] Working principle: First, the filament and core yarn are wound onto the sidewalls of the first roller 23 and the second roller 24 in the two sets of tension adjustment components 2, respectively. Then, one end of the core yarn is fed into the first inlet 31 after passing through the first through hole 131, and the filament is fed into the second inlet 32 ​​after passing through the second through hole 132. After being covered by the covering machine body 3, it is discharged from the outlet 33. When the filament or core yarn becomes loose, the second roller 24 moves downward along the first mounting post 211, thereby tensioning the filament or core yarn. When the filament or core yarn becomes taut, the second roller 24 moves downward along the first mounting post 211. The column 211 moves upward, thereby restoring the filament or core yarn to a relaxed state, preventing damage to the filament or core yarn due to excessive tension, and adjusting the tension to improve the quality and tension of the covered yarn to ensure the consistency of yarn winding. Secondly, using the elastic force of the first spring 253, the first spring 253 pushes the end of the baffle 254 away from the first spring 253 to slide out of the second mounting groove 252, thereby limiting the counterweight 256 and increasing stability. Then, the counterweight 256 is used to adjust the overall weight of the adjusting seat 25, thereby adjusting the tension.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
