[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: a feeding machine for producing all-aluminum nose bridge strips, including an operating table 16, with a guiding mechanism connected to one end of the operating table 16. The guiding mechanism includes multiple first supports 6 vertically connected to the top of the operating table 16, with first support rollers 8 rotatably connected to the upper ends of each first support 6 via second rotating shafts 15. Second supports 20, perpendicularly connected to the operating table 16, are arranged between the first supports 6, with second support rollers 13 rotatably connected to the second supports 20 via third rotating shafts 18. Figure 1 As shown, multiple annular grooves 14 are provided on the outer walls of both the second support roller 13 and the first support roller 8, and the nose bridge strip ( Figure 1 The annular groove 14 (indicated by the middle arrow A) is wound sequentially around the outer wall of the second support roller 13 and the first support roller 8, which can effectively guide the nose bridge strip and thus realize the winding process of the nose bridge strip in batches.

[0023] like Figure 1 , 4As shown, to buffer the tension generated by the nose bridge strip, an opening 19 is provided at the top of the second support 20. The top of the opening 19 is sealed by the top seat 7, and a mounting seat 12 is slidably arranged in the opening 19. The third rotating shaft 18 and the mounting seat 12 are rotatably connected. A screw 10 is vertically connected in the opening 19. The screw 10 passes through the second support 20 and the top seat 7 in sequence, and a locking nut 9 that abuts against the top seat 7 is threadedly connected to the top of the screw 10. Return springs 11 coaxial with the screw 10 are connected to both sides of the second support 20. The ends of the return springs 11 located on both sides of the second support 20 are connected to the top seat 7 and the opening 19, respectively.

[0024] During the movement of the nose bridge strip, it exerts a force on the second support roller 13, which in turn puts pressure on the return spring 11. Under the elastic force of the return spring 11, the tension can be effectively buffered. At the same time, the top seat 7 is detachably installed at the top of the opening 19, which facilitates the replacement and maintenance of the second support roller 13 and increases the service life of the device.

[0025] like Figure 1 , 2 As shown in Figure 3, a mounting box 2 is connected to the other end of the operating table 16. Multiple parallel support shafts 4 are slidably arranged on the side of the mounting box 2 near the guide mechanism. A first sliding seat 17 is connected to the mounting box 2. The support shafts 4 and the first sliding seat 17 are coaxially arranged and slidably connected. Multiple guide rollers 5 are coaxially connected to each support shaft 4. The nose bridge strip extends to the support shaft 4 and is wound around the guide rollers 5, thereby providing a good guiding effect for the nose bridge strip.

[0026] In summary, when using the feeder for producing all-aluminum nose bridge strips, one end of the support shaft 4 extends into the mounting box 2 and is fixedly connected to the first connecting seat 22. The mounting box 2 is tightly fitted with a second connecting seat 23 that is parallel to the first connecting seat 22, and an electric telescopic rod 24 is horizontally connected between the second connecting seat 23 and the first connecting seat 22. Under the pushing action of the electric telescopic rod 24, the guide roller 5 and the support shaft 4 can be driven to slide back and forth in the horizontal direction, thereby driving the nose bridge strip to move back and forth, so that the nose bridge strip can be normally wound.

[0027] Meanwhile, in order to improve the stability of the sliding of the support shaft 4, a guide rod 25 parallel to the electric telescopic rod 24 is fastened to one side of the second connecting seat 23. The guide rod 25 passes through the first connecting seat 22 and is fastened to the side wall of the mounting box 2. A second sliding seat 26 is connected to the first connecting seat 22. The guide rod 25 and the second sliding seat 26 are coaxially arranged and slidably connected.

[0028] like Figure 1As shown, a plurality of first rotating shafts 3 are rotatably connected to the end of the mounting box 2 away from the support shaft 4. One end of the first rotating shaft 3 extends into the mounting box 2, and a plurality of sprockets 21 are coaxially connected to the end of the first rotating shaft 3. Adjacent sprockets 21 are connected by chains. A motor 27 is connected to the first rotating shaft 3 at one end, and a winding roller 1 is coaxially connected to the first rotating shaft 3. The number of winding rollers 1 and guide rollers 5 is equal. The nose strip driven by the guide rollers 5 and the support shaft 4 can be wound on the outer wall of the winding roller 1. Since the number of winding rollers 1 and guide rollers 5 is equal, batch feeding and winding processing of nose strips can be carried out, which greatly improves the production efficiency.
