[0001] The utility model relates to the technical field of yarn processing, and particularly relates to a wire carrier with an extension support mechanism. Background Technique
[0002] During the yarn processing process, the wire carrier, as an important auxiliary device, plays a key role in controlling the tension of the yarn and guiding its direction. It is usually composed of a fixed bracket, a guide roller and other auxiliary mechanisms. When in use, the guide roller is used to support and guide the yarn during the processing process, so as to prevent it from deviating or winding, and at the same time provide the necessary supporting force, so that the yarn can smoothly pass through each processing link.
[0003] However, when the guide roller of the traditional wire carrier is in use, since most of its sizes are fixed, when supporting and guiding yarns with different diameters, it is often necessary to select a suitable guide roller, which makes the use of the wire carrier inconvenient, thus reducing the versatility and flexibility of the wire carrier. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a wire carrier with an extension support mechanism to solve the technical problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A wire carrier with an extension support mechanism, including a fixed bracket, one end of the fixed bracket is provided with a guide roller, and the guide roller includes a support frame and a movable frame. One end of the support frame is connected to the fixed bracket through a support shaft, and the other end of the support frame is slidably connected with the movable frame. An extension support mechanism connected to the support frame is arranged through the inside of the movable frame. The extension support mechanism includes a rotating handle, a lead screw, a threaded barrel and a guide block. The threaded barrel is welded and connected to the inner side of the support frame, and the inside of the movable frame is connected with a lead screw extending to the inside of the threaded barrel through a bearing.
[0006] Preferably, the lead screw is threadedly connected with the threaded barrel, and a rotating handle is welded and connected to the end of the lead screw away from the threaded barrel.
[0007] Preferably, guide blocks are welded and connected to both ends of the threaded barrel, guide rods penetrating through the guide blocks are symmetrically arranged on the inner side of the movable frame, and the movable frame and the support frame form a sliding structure through the guide blocks and the guide rods.
[0008] Preferably, a slider is welded and connected to the outer side of the support frame, a chute is opened on the outer surface of the movable frame, and the movable frame and the support frame form a sliding structure through the slider and the chute.
[0009] Preferably, a locking mechanism is provided at the front end of the movable frame, and the locking mechanism is composed of a gear, a toothed plate, a lifting frame, a cross plate and a return spring.
[0010] Preferably, the gear is welded to the outer surface of the lead screw, the cross plate is welded to the front end of the movable frame, the lifting frame is slidably connected to the inside of the cross plate, and a toothed plate meshed with the gear is welded to one side of the lifting frame.
[0011] Preferably, a return spring is welded between the lifting frame and the cross plate, and the lifting frame and the cross plate form an elastic structure through the return spring.
[0012] In summary, the present utility model mainly has the following beneficial effects:
[0013] When the existing wire carrier is in use, since the sizes of the guide rollers are mostly fixed, the use of the wire carrier is more inconvenient, thereby reducing the versatility and flexibility of the wire carrier.

[0020] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

During use, the guide roller 2 is used to support and guide the yarn during the processing process, so as to prevent it from deviating or winding, and at the same time provide the necessary support force, so that the yarn can smoothly pass through each processing link.
[0022] Referring to Fig. Figure 2 and Figure 3 it can be seen that a slider 5 is welded and connected to the outer side of the support frame 201, a chute 6 is opened on the outer surface of the movable frame 202, and the movable frame 202 and the support frame 201 form a sliding structure through the slider 5 and the chute 6, which can play a role in supporting and limiting, so that the movable frame 202 slides horizontally to prevent deviation.
[0023] Referring to Figure 1 , Figure 2 and Figure 3 it can be seen that a locking mechanism 4 is provided at the front end of the movable frame 202. The locking mechanism 4 is composed of a gear 401, a toothed plate 402, a lifting frame 403, a cross plate 404 and a return spring 405. The gear 401 is welded and connected to the outer surface of the lead screw 302, the cross plate 404 is welded and connected to the front end of the movable frame 202, the lifting frame 403 is slidably connected to the inside of the cross plate 404, a toothed plate 402 meshed with the gear 401 is welded and connected to one side of the lifting frame 403, a return spring 405 is welded and connected between the lifting frame 403 and the cross plate 404, and the lifting frame 403 and the cross plate 404 form an elastic structure through the return spring 405;
[0024] Referring to Figure 2 and Figure 3It can be seen that since the lifting frame 403 and the cross plate 404 are elastically connected by the return spring 405, after the extension operation of the guide roller 2 is completed, the lifting frame 403 is released, and the lifting frame 403 will be reset under the action of the return spring 405 and the toothed plate 402 will be engaged with the gear 401, thereby realizing the locking of the lead screw 302 and preventing the lead screw 302 from rotating self - sufficiently, so as to increase the stability during use.
[0025] Refer to Figure 1 、 Figure 2 and Figure 3 It can be seen that an extension support mechanism 3 connected to the support frame 201 is disposed through the inside of the movable frame 202. The extension support mechanism 3 includes a rotating handle 301, a lead screw 302, a threaded barrel 303 and a guide block 304. The threaded barrel 303 is welded to the inner side of the support frame 201. A lead screw 302 extending to the inside of the threaded barrel 303 is connected to the inside of the movable frame 202 through a bearing. The lead screw 302 is threadedly connected to the threaded barrel 303. A rotating handle 301 is welded to one end of the lead screw 302 away from the threaded barrel 303;

The movable frame 202 and the support frame 201 form a sliding structure through the guide blocks 304 and the guide rods 305, which can play a role in supporting and limiting, so as to prevent the movable frame 202 from shifting.
[0028] The working principle of the present utility model is as follows: When using the lead frame with an extension support mechanism, by pulling the lifting frame 403 to one side, the toothed plate 402 is separated from the gear 401. At this time, the lead screw 302 can be rotated by rotating the rotating handle 301, and the movable frame 202 moves horizontally relative to the support frame 201, so as to realize the extension operation of the guide roller 2 according to the actual processing requirements of the yarn.
