Description

Technical Field

[0001] This utility model relates to the field of yarn guiding devices, and more specifically, to a yarn guiding device for covered yarn. Background Technology

[0002] Spandex-covered yarn is a type of yarn with spandex filaments as the core. The filaments of spandex-covered yarn are spirally wrapped around the elongated spandex filaments, and then elastic yarn is added. A yarn guiding device is used during the production process of spandex-covered yarn.

[0003] A search revealed that Chinese patent CN219430210U discloses a "yarn guiding device for producing spandex covered yarn," comprising a support plate with multiple fixed shafts. Each fixed shaft rotatably connects to two guide wheels and an adjusting wheel. Each fixed shaft has a fixing mechanism, including a limiting ring, a connecting cylinder, two limiting posts, two sliding plates, two fixing frames, two springs, and two connecting rods. The limiting posts are slidably mounted on the connecting cylinder, and the connecting rods are slidably mounted on the fixed shafts. This invention utilizes the cooperation of the limiting ring, connecting cylinder, limiting posts, sliding plates, fixing frames, and connecting rods. The limiting ring and connecting cylinder limit the position of the guide wheels or adjusting wheels, the limiting posts limit the position of the connecting cylinder, and the connecting rods pull the limiting posts away from the connecting cylinder. This facilitates the installation and disassembly of the guide wheels and adjusting wheels, allowing for independent disassembly, maintenance, or replacement. However, it still has the following drawbacks:

[0004] (1) When disassembling and maintaining the existing yarn guiding device, the yarn guiding wheel can only be removed from the shaft. The shaft also needs maintenance after long-term operation, but it cannot be disassembled separately and can only be maintained on the equipment. The operation process is blocked by other yarn guiding rollers around it, which affects the convenience of maintenance.

[0005] (2) Existing yarn guiding devices need to guide different numbers of yarn bundles during the yarn guiding process. However, the existing yarn guiding devices can only change the amount of yarn guided by changing the model and size of the yarn guiding roller. This requires repeated disassembly and installation, which reduces the ease of use of the yarn guiding device.

[0006] Therefore, we have made improvements to this and proposed a yarn guide device for covered yarn. Utility Model Content

[0007] The purpose of this invention is to address the problem that existing yarn guiding devices are not completely disassembled and cannot be adaptively adjusted according to the amount of yarn being guided.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a yarn guide device for covered yarn, including a back plate 1, a mounting assembly is provided on the front side of the back plate 1, and an adjustment assembly is provided on the front side of the mounting assembly.

[0036] The mounting assembly includes a bearing 201 disposed on the front surface of the rear plate 1, a slot 202 opened on the front side of the bearing 201, and a yarn guide roller 203 detachably inserted into the slot 202.

[0037] The pitch adjustment assembly includes an inner groove 301 inside the upper front side of the yarn guide roller 203. A first bevel gear 302 is provided in the inner groove 301 perpendicular to the inner wall of the yarn guide roller 203. A knob 303 is connected to the outer wall of the first bevel gear 302.

[0038] like Figure 3As shown, grooves 204 are provided on the upper and lower surfaces of the yarn guide roller 203, and slots 205 are provided on the upper and lower surfaces of the slot 202. A plate 206 that cooperates with the groove 204 is movably arranged inside the slot 205. The groove 204 and the plate 206 are aligned. When the tension on the plate 206 is released, the telescopic rod 209 and the spring 210 push the side plate 208, causing the plate 206 to be inserted into the aligned groove 204, thus completing the quick fixing of the yarn guide roller 203.

[0039] like Figure 3 As shown, the side wall of the groove 204 is provided with a side groove 207, and the side wall of the insert plate 206 is provided with a side plate 208 that cooperates with the side groove 207. Pulling the insert plate 206 makes it slide outward in the groove 205, which drives the two side plates 208 to move in and out of the side groove 207, compressing the telescopic rod 209 and the spring 210 to retract them. At the same time, the insert plate 206 moves out of and out of the groove 204, and the yarn guide roller 203 can be pulled forward to disengage it from the slot 202.

[0040] like Figure 3 As shown, a telescopic rod 209 is provided on the side wall of the side plate 208. A spring 210 is fitted on the outer wall of the telescopic rod 209. The telescopic rod 209 and the spring 210 compress each other to retract, which at the same time causes the insert 206 to move out of the groove 204. This allows the guide roller 203 to be pulled forward to disengage from the slot 202, thus completing the disassembly of the guide roller 203. After maintenance of the guide roller 203, it is reinserted into the slot 202 so that the groove 204 is aligned with the insert 206. The tension on the insert 206 is released, and the telescopic rod 209 and the spring 210 push the side plate 208, causing the insert 206 to be inserted into the aligned groove 204.

[0041] like Figure 4 As shown, the inner wall of the inner groove 301 near the rear plate 1 is provided with a second bevel gear 304 that cooperates with the first bevel gear 302. Twisting the knob 303 drives the first bevel gear 302 connected to it to rotate, and meshing drives the second bevel gear 304 to rotate.

[0042] like Figure 4 As shown, the inner groove 301 has a sliding groove 305 on the outer side near the back plate 1. A screw 306 is installed inside the sliding groove 305. A sleeve plate 307 is fitted on the outer wall of the screw 306. A collar 310 is fitted on the outer wall of the sleeve plate 307. When the screw 306 rotates, the sleeve plate 307 slides in the sliding groove 305 through the thread engagement of the outer wall. Under the limitation of the limiting plate 309 embedded in the limiting groove 308, the collar 310 slides stably on the outer wall of the yarn guide roller 203, adjusting the distance between the collar and the fixing ring on the outer wall of the yarn guide roller 203.

[0043] like Figure 4As shown, a limiting groove 308 is provided on the side wall of the slide groove 305, and a limiting plate 309 is provided on the side wall of the sleeve plate 307 to cooperate with the limiting groove 308. Under the limiting position of the limiting plate 309 embedded in the limiting groove 308, the collar 310 is driven to slide stably on the outer wall of the yarn guide roller 203, and the distance between the collar and the fixed ring on the outer wall of the yarn guide roller 203 is adjusted, thereby adjusting the number of guided covering yarn bundles.

[0044] Specifically, when using this yarn guiding device: When maintenance or replacement of the yarn guiding roller 203 is required, pull the insert plate 206 outwards to slide it outwards within the slot 205, causing the side plates 208 to move in and out of the side groove 207. This compresses the telescopic rod 209 and spring 210, causing them to contract. Simultaneously, the insert plate 206 moves out of and out of the slot 204, allowing the yarn guiding roller 203 to be pulled forward to disengage from the slot 202, thus completing the disassembly of the yarn guiding roller 203. After maintenance, reinsert the yarn guiding roller 203 into the slot 202, aligning the slot 204 with the insert plate 206. Release the tension on the insert plate 206; the telescopic rod 209 and spring 210 push the side plate 208, causing the insert plate 206 to insert... Within the aligned groove 204, the guide roller 203 is quickly fixed, facilitating efficient maintenance. When it is necessary to adjust the guide roller 203 to guide different numbers of yarn bundles, turning the knob 303 drives the first bevel gear 302 connected to it to rotate, which in turn drives the second bevel gear 304 to rotate, which in turn drives the screw 306 connected to it to rotate. Through the engagement of the outer wall thread, the sleeve plate 307 slides in the slide groove 305. Under the limitation of the limiting plate 309 embedded in the limiting groove 308, the collar 310 slides stably on the outer wall of the guide roller 203. Adjusting the distance between the collar and the fixing ring on the outer wall of the guide roller 203 adjusts the number of covered yarn bundles guided, improving the ease of use of the yarn guiding device.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
