Detailed Implementation

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. 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.

[0023] Example:

[0024] like Figures 1 to 5 As shown, this utility model discloses a semi-automatic bow forming machine, including a work box 12 and a stand set at the lower end of the work box 12. Two telescopic components are symmetrically arranged on the left and right sides of the work box 12, as shown... Figure 1As shown, the two telescopic components are arranged in a V-shape with their inclinations towards each other. Each telescopic component specifically includes a slide rail 21 and a slider 22 slidably disposed within the slide rail 21. A pull plate 23 is fixedly disposed at the end of the slider 22, extending away from the slide rail 21, and a hook 24 is disposed at the end of the pull plate 23 away from the slider 22. Simultaneously, a rope-tying mechanism is provided on the upright frame for driving the slider 22 to slide on the slide rail 21. The rope-tying mechanism is similar to existing technology, specifically including a pedal 28 and a pull rope 29. One end of the pull rope 29 is fixedly connected to the slider 22. A guide post 25 is disposed at the end of the slide rail 21 away from the pull plate 23. The pile 25 has a through-hole 26 for the pull rope 29 to pass through. The other end of the pull rope 29 passes through the through-hole 26 and extends outward to be fixedly connected to the pedal 28. In addition, the working box 12 is provided with several guide posts 44. These guide posts 44 are mainly used to make the rope run along a predetermined path. The pull rope 29 first passes through the through-hole 26, then passes around each guide post 44, and finally is fixedly connected to the pedal 28. Finally, the slide rail 21 is provided with an elastic support member 27. The elastic support member 27 is positioned between the end of the slide rail 21 away from the pull plate 23 and the slider 22. When the pedal 28 no longer applies force, the elastic support member 27 is used to push the slider 22 to reset. The elastic support member 27 can be a spring.

[0025] In order for the device to produce bows of different sizes, the work box 12 is equipped with a left-right translation mechanism for moving the two slide rails 21 away from each other or closer to each other.

[0026] The left-right translation mechanism specifically includes a lead screw 31 and a motor 32. The motor 32 is fixedly mounted on the work box 12, while the lead screw 31 is rotatably mounted inside the work box 12 and connected to the output end of the motor 32. In this structure, the slide rail 21 slides left and right within the work box 12, and a connecting block 33 is provided at the lower end of the slide rail 21. This connecting block 33 is sleeved on the outside of the lead screw 31 and connected to the lead screw 31 via a threaded connection. Furthermore, in this structure, the slide rails 21 are respectively located at the left and right ends of the lead screw 31, making the lead screw 31 a bidirectional lead screw. Through this arrangement, after the motor 32 drives the lead screw 31 to rotate, the distance between the slide rails 21 changes, thus changing the distance between the intersection point of the hook piece 24 and the pull plate 23. When the slider 22 is then slid, the hook piece 24 can tie bows of different sizes.

[0027] Accordingly, to ensure the effectiveness of the pull rope 29, a length-changing mechanism is provided on the pull rope 29. This length-changing mechanism specifically includes a left clamping member 41 and a right clamping member 42 detachably disposed at the right end of the left clamping member 41, such as... Figure 3As shown, two fixing grooves 43 are formed between the opposite side walls of the left clamping member 41 and the right clamping member 42. When the left clamping member 41 and the right clamping member 42 are pressed on both sides of the pull rope 29, the pull rope 29 passes through the two fixing grooves 43 in sequence. People can control the length of the pull rope 29 between the two fixing grooves 43 to tension the pull rope 29 so that the pull rope 29 can pull the slider 22 to slide every time the pedal 28 is stepped on.

[0028] The left clamp 41 and the right clamp 42 are detachably connected by bolts.

[0029] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
