[0002] Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. During the yarn transmission process, a tensioner is usually required to maintain its tension state to facilitate subsequent winding, storage or textile processing. However, the existing covered yarn is prone to looseness during the winding process, resulting in chaotic yarn winding, which in turn affects the yarn winding and textile effect. In addition, the existing tensioner specifications are relatively single, and other limiting structures are often required to meet the needs of yarn winding and tension adjustment.

[0003] In order to solve the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, the Chinese patent document discloses a textile guide roller for an automated textile machine 201910896061.3, which includes two guide roller discs and one or more guide rollers, one or more guide rollers are arranged around the guide roller discs and connected to the two guide roller discs through one or more guide rollers, and the two guide roller discs and one or more guide rollers constitute the guide roller body; both sides of each guide roller are installed in the bearings embedded in the guide roller disc, and the guide roller extends into the linkage cavity inside the guide roller disc, and a negative pressure device is protruded on the middle inner side of each guide roller disc.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4 As shown, a tensioning guide roller for nylon coated yarn includes a guide roller body 1, the guide roller body 1 has a plurality of sub-guide rollers 2 arranged in a central symmetrical manner, a linkage component 3 for driving the sub-guide rollers 2 to separate or merge from each other is installed between the ends of the sub-guide rollers 2, the linkage component 3 is connected to the adjustment component 4 in the guide roller body 1, and the two ends of the guide roller body 1 are respectively fixed with assembly components 5. The operator manually applies an adjustment torque to the adjustment component 4, and the linkage component 3 is then driven to drive the sub-guide rollers 2 to approach or move away from the central axis of the guide roller body 1, and the sub-guide rollers 2 are in direct contact with the yarn and conduct the yarn.

[0024] Specifically, the guide roller body 1 includes a central rod body 11, and a rotating base 12 is fixed at both ends of the central rod body 11, and the rotating base 12 is connected to the mounting base 13 through a rotating bearing, and the central rod body 11 and the rotating base 12 rotate relative to the mounting base 13. The linkage component 3 is installed on the rotating base 12, and the assembly component 5 is fixedly connected to the mounting base 13, and the assembly component 5 fixes the mounting base 13 and the corresponding nylon coated yarn conductive structure relatively.

[0025] In depth, unlike the conventional radial adjustment structure, the linkage assembly 3 in the present application includes a linkage arm 31 hinged to the rotating base 12, and the sub-guide roller 2 is rotatably installed at the end of the linkage arm 31. When the linkage arm 31 swings, the radial orientation of the sub-guide roller 2 relative to the tensioning guide roller as a whole is adjusted accordingly. The linkage arm 31 is a curved structure and is arranged in a central symmetric manner relative to the rotating base 12. The linkage arm 31 is provided with a first linkage groove 32, and the mounting base 13 is rotatably connected with a linkage disk 33. The linkage disk 33 is provided with a second linkage groove 34 which is arranged obliquely and corresponds to the first linkage groove 32 one by one, and a linkage block 35 is slidably installed between the first linkage groove 32 and the second linkage groove 34. The sub-guide roller 2 drives the linkage disk 33 to rotate relative to the rotating base 12. During the rotation process, the linkage block 35 slides in the first linkage groove 32 and the second linkage groove 34 and adjusts the radial and circumferential orientations, and the linkage arm 31 where the first linkage groove 32 is located also swings to adjust the position of the sub-guide roller 2.

[0026] Furthermore, in order to improve the adjustment accuracy of the linkage assembly 3, the adjustment assembly 4 includes an adjustment toothed ring 41 fixed on the linkage disk 33 and extending in the circumferential direction, the adjustment toothed ring 41 is transmission-connected to a planetary gear set 42 installed on the rotating base 12, and an adjustment handwheel 43 transmission-connected to the planetary gear set 42 is installed at the end of the central rod body 11. The planetary gear set 42 is used for speed transmission, thereby improving the adjustment accuracy of the adjustment handwheel 43 for the rotation angle of the linkage disk 33.

[0027] Furthermore, the assembly assembly 5 realizes the position fixation of the guide roller body 1, and includes an assembly foot 51 arranged on the mounting base 13, and the assembly foot 51 is respectively provided with a strip-shaped assembly hole 52, and the assembly hole 52 is internally threaded with a threaded member for locking and fixing. The assembly foot 51 is symmetrically arranged to maintain the central axis of the guide roller body 1 parallel to the horizontal plane.

[0028] In addition, each sub-guide roller 2 rotates independently, and each includes a support rod 21, a roller sleeve 22 is rotatably mounted on the outer side of the support rod 21, a support frame 23 is arranged between the support rod 21 and the roller sleeve 22, and a yarn guide assembly is distributed on the surface of the roller sleeve 22. The surface of the roller sleeve 22 is usually provided with a limit groove for limiting the yarn conduction path.

[0029] At the same time, in order to facilitate the rapid assembly of the guide roller 2, the support frame 23 is cylindrical and has cavities extending along the axial direction evenly distributed inside. The support frame 23 has an interference fit with the support rod 21 and the roller sleeve 22. The support frame 23 is elastic and is filled between the support rod 21 and the roller sleeve 22 to play a supporting role.

[0030] It can be seen that the yarn guide assembly includes yarn guide ribs 24 arranged along the axial direction of the roller sleeve 22, and the yarn guide ribs 24 surround the roller sleeve 22 circumferentially and are integrally formed with the roller sleeve 22. Limiting grooves for the yarns to be inserted are distributed between the yarn guide ribs 24 to isolate the yarns from each other and avoid interference during transmission.

[0031] Obviously, protective cover plates 6 are installed at both ends of the guide roller body 1 to cover the corresponding linkage components 3 to prevent external foreign matter from invading the linkage components 3 and the adjustment components 4 and affecting the adjustment accuracy.

[0032] Preferably, the guide roller body 1 has a built-in photo sensor to sense the yarn, and when the yarn breaks, an alarm signal is sent to alert maintenance personnel.

[0033] In summary, the principle of this embodiment is that the guide roller body 1 is circumferentially distributed with sub-guide rollers 2, and each sub-guide roller 2 is moved closer to or farther away from the central axis of the guide roller body 1 under the transmission action of the linkage component 3 and the adjustment component 4, thereby adjusting the tension of the yarn.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0035] Although the present invention uses more terms such as guide roller body 1, central rod body 11, rotating base 12, mounting base 13, sub-guide roller 2, support rod 21, roller sleeve 22, support frame 23, yarn guide rib 24, linkage assembly 3, linkage arm 31, first linkage groove 32, linkage disk 33, second linkage groove 34, linkage block 35, adjustment assembly 4, adjustment gear ring 41, planetary gear set 42, adjustment hand wheel 43, assembly assembly 5, assembly foot 51, assembly hole 52, protective cover plate 6, etc., it does not exclude the possibility of using other terms.
