Description

Technical Field

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

[0002] Covered yarn is a composite yarn formed by using elastic fibers as the core yarn and wrapping them with helical short fibers or filaments, combining the strength of the core yarn with the characteristics of the outer fibers. The spinning process of covered yarn requires a yarn guiding device. Using specific equipment, filaments or short fibers are helically wound onto core yarns such as spandex, forming an elastic composite yarn. This process ensures that the outer material tightly wraps the core yarn by precisely controlling the yarn guiding path and tension, ultimately resulting in a yarn with uniform yarn consistency and controllable elasticity.

[0003] Chinese utility model patent CN211227494U discloses a yarn guiding device for guiding covered yarn, including "two support plates; the two support plates are vertically installed on a base; a lead screw is rotatably set on the inner sidewall of the two support plates; two guide columns are provided; both guide columns are set on the inner sidewall of the two support plates; a sliding block is provided with a threaded hole that cooperates with the lead screw and is threadedly connected to the lead screw through the threaded hole; the sliding block is provided with two through holes that cooperate with the guide columns and are slidably connected to the guide columns through the through holes"; however, when using guide columns to guide covered yarn, due to the different specifications of the collecting end, the position angle of the collecting end will have certain differences. However, guide columns with fixed angles often cannot well adapt to the yarn guiding requirements of covered yarn, causing the covered yarn to deviate during yarn guiding, thus reducing the adaptability of the yarn guiding device. Utility Model Content

[0004] The purpose of this utility model is to provide a composite yarn guiding device for covered yarn, so as to solve the problem mentioned in the background art that due to the different specifications of the collecting end, there will be certain differences in the position angle of the collecting end. However, the guide column with a fixed angle often cannot be well adapted to the yarn guiding requirements of the covered yarn, causing the covered yarn to deviate during yarn guiding, which in turn reduces the adaptability of the yarn guiding device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a covered yarn composite yarn guiding device, including an operating table, a fixed frame installed at one top end of the operating table, a conveying roller rotatably connected inside the fixed frame, a yarn guiding assembly provided on one side of the fixed frame, and a guide assembly installed at the other top end of the operating table.

[0006] The guide assembly includes a fixed base, which is fixedly connected to one end of the operating table. A guide motor is installed at one end of the fixed base, and a guide frame is driven and connected to one end of the guide motor. Buffer grooves are embedded in the inner walls on both sides of the top of the guide frame. Buffer springs are installed at the bottom of the buffer grooves, and buffer blocks are installed at the top of the buffer springs. A guide rod is rotatably connected to one end of the buffer block.

[0007] The beneficial effects of this utility model are as follows: by setting the yarn guiding assembly to a liftable structure, it is convenient to adjust the distance between the two yarn guiding rollers according to the specifications of the covering yarn. With the motor driving the yarn guiding rollers to reciprocate, the position of the yarn guiding rollers is always adapted to the feeding position of the covering yarn, thereby improving the adaptability of the yarn guiding device. At the same time, an angle-adjustable guide rod is set at the other end of the operating table, which is convenient to adjust the angle of the guide rod according to the position of the collecting end, so as to facilitate the collecting end to collect the covering yarn, thereby improving the use effect of the yarn guiding device.

[0008] To enable quick installation and removal of the covered yarn in the yarn guide device:

[0009] Further configuration: the fixing frame is two opposing L-shaped structures, the top of the fixing frame is through a fixing rod, and both ends of the fixing rod are provided with external thread structures. The two ends of the fixing rod are threaded with fixing nuts, and the fixing nuts are in contact with the outer wall of the fixing frame. The fixing rod passes through the center of the conveying roller.

[0010] By adopting the above technical solution, a fixed rod is set to pass through the conveyor roller, allowing the conveyor roller to rotate between two fixed frames. With the help of the fixing nut, the conveyor roller can be quickly installed and removed from the fixed frame, improving the efficiency of the installation and removal of the covered yarn conveyor roller, and thus improving the efficiency of the yarn guiding device.

[0011] To ensure the guide roller is aligned with the position of the covered yarn on the conveyor roller:

[0012] The yarn guiding assembly is further configured such that: the yarn guiding base includes a yarn guiding base, which is mounted on the top of the operating table; an adjusting motor is mounted on one end of the yarn guiding base; the adjusting motor drives and connects to an adjusting screw, which is rotatably connected to the inside of the yarn guiding base; an adjusting block is threaded onto the outside of the adjusting screw, and the adjusting block is slidably connected to the inside of the yarn guiding base; and the length of the yarn guiding base is the same as the length of the conveying roller.

[0013] By adopting the above technical solution, the motor-driven adjusting block is set to slide within the yarn guide base, so that the yarn guide roller is always parallel to the position of the yarn on the conveying roller when guiding the covered yarn, thereby ensuring the stable conveying of the covered yarn during yarn guiding and improving the yarn guiding effect of the covered yarn in the yarn guiding device.

[0014] To accommodate different specifications of covered yarn:

[0015] Further configuration: a yarn guide frame is installed on both sides of the top of the adjusting block, a lower yarn guide roller is rotatably connected inside the yarn guide frame, and the top height of the lower yarn guide roller is the same as the center height of the conveying roller. A yarn guide groove passes through the top of the yarn guide frame, a yarn guide rod passes through the inside of the yarn guide groove, and the outer walls of both ends of the yarn guide rod are provided with external thread structures. An upper yarn guide roller passes through the outside of the yarn guide rod, and locking nuts are threaded to both ends of the yarn guide rod.

[0016] By adopting the above technical solution, an upper guide roller that can be adjusted up and down is set up in conjunction with a lower guide roller that is fixed in position. This makes it easy to adjust the distance between the two guide rollers according to the specifications of the covered yarn, thereby improving the adaptability of the yarn guiding device and thus improving the yarn guiding effect of the covered yarn in the yarn guiding device.

[0017] To enable adjustment of the guide rod angle based on the position of the collection end:

[0018] The guide frame is further configured as follows: the guide frame is a U-shaped frame structure, and the inner walls on both sides of the top of the U-shaped end of the guide frame are embedded with buffer grooves, and the bottom sides of the guide frame form a rotating connection structure with the fixed base, and the buffer block and the buffer groove form a sliding connection structure.

[0019] By adopting the above technical solution, the angle of the guide rod on the guide frame is adjusted by setting the guide frame driven by the motor to rotate on the fixed base. This makes it easy to adjust the angle of the guide rod according to the position of the collecting end, improves the adaptability of the yarn guiding device, and thus ensures the stability of the collecting end after yarn guiding.

[0020] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

A guide rod 507 is rotatably connected to one end of the buffer block 506.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the fixing frame 2 is two opposing L-shaped structures. The top of the fixing frame 2 is through a fixing rod 201, and both ends of the fixing rod 201 are provided with external thread structures. The two ends of the fixing rod 201 are threaded with fixing nuts 202, and the fixing nuts 202 are in close contact with the outer wall of the fixing frame 2. The fixing rod 201 passes through the center of the conveying roller 3.

[0030] In this embodiment, as Figure 1 and Figure 3As shown, the yarn guiding assembly 4 includes a yarn guiding base 401, which is mounted on the top of the operating table 1. An adjusting motor 402 is mounted on one end of the yarn guiding base 401. The adjusting motor 402 drives and connects to an adjusting screw 403, which is rotatably connected to the inside of the yarn guiding base 401. An adjusting block 404 is threadedly connected to the outside of the adjusting screw 403, and the adjusting block 404 is slidably connected to the inside of the yarn guiding base 401. The length of the yarn guiding base 401 is the same as the length of the conveying roller 3.

[0031] In this embodiment, as Figure 1 and Figure 3 As shown, yarn guide frames 405 are respectively installed on both sides of the top of the adjusting block 404. The lower yarn guide roller 406 is rotatably connected inside the yarn guide frame 405, and the top height of the lower yarn guide roller 406 is the same as the center height of the conveying roller 3.

[0033] The computer software involved in the hardware carriers such as the regulating motor and the guiding motor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0034] Therefore, the "adjusting motor" and "guide motor" involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the yarn guiding device of this application, so as to solve the corresponding technical problems to be solved by this application.

[0035] The working process of this covered yarn composite yarn guiding device is as follows:

[0036] First, rotate the fixing nuts 202 at both ends of the fixing rod 201 on the fixing frame 2 to remove the fixing rod 201 from the fixing frame 2. Pass the center of the covering yarn conveying roller 3 that needs to be guided through the fixing rod 201, and then fix the fixing rod 201 back into the fixing frame 2 using the fixing nuts 202.

[0037] Then, one end of the covering yarn on the conveying roller 3 is passed between the lower guide roller 406 and the upper guide roller 409 in the yarn guide frame 405. At the same time, the two ends of the guide rod 408 that passes through the upper guide roller 409 in the yarn guide groove 407 inside the yarn guide frame 405 slide up and down, so that the covering yarn slides between the upper and lower guide rollers respectively. The guide rod 408 is locked in the position in the yarn guide groove 407 inside the yarn guide frame 405 by the locking nut 410.

[0038] Next, start the guide motor 502 (model: MS1-R) at one end of the fixed base 501 to drive the guide frame 503 to rotate inside the fixed base 501, so that the position of the guide rod 507 at the top of the guide frame 503 is adapted to the position of the collecting end, and the end of the covered yarn is attached to the top of the guide rod 507 and wrapped and fixed with the collecting end.

[0039] Finally, while the collecting end is started to guide and collect the covered yarn, the adjusting motor 402 (model: MS1-R) is started to drive the adjusting screw 403 to rotate, causing the adjusting block 404 to slide in the yarn guide base 401. This, in turn, causes the positions of the two yarn guide rollers at the top of the adjusting block 404 to be adjusted, so that the positions of the yarn guide rollers correspond to the conveying positions of the covered yarn on the conveying roller 3. At the same time, when the covered yarn is driven on the guide rod 507, the buffer spring 505 in the buffer groove 504 in the guide frame 503, together with the buffer block 506, buffers the covered yarn during the guiding process, ensuring the tension of the covered yarn in the yarn guide device and improving the yarn guiding quality. After the yarn guiding is completed, all components can be reset.
