[0014] The present invention is described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a front view schematic diagram of an automatic thread-knotting mechanism of the present utility model.
[0016] Figure 2 for Figure 1 An enlarged schematic diagram of part J in FIG. DETAILED DESCRIPTION Example
[0017] like Figures 1 to 2As shown, an automatic silk-binding mechanism includes a silk-binding drum 601, the silk-binding drum 601 is provided with a flange ring 602, an embedded groove 603 is provided inside the flange ring 602, a rotating shaft 604 is provided in the embedded groove 603, a clip 605 is installed on the rotating shaft 604, the clip 605 includes a clip bottom plate and a dial plate, the clip bottom plate is connected to the dial plate, and a V shape is formed between the dial plate and the clip bottom plate. The clip bottom plate is pressed against the surface of the silk-binding drum 601, and the dial plate is rotated by a spring 606. The shaft 604 is the center of rotation to press the clip 605 onto the surface of the wire tube 601. One end of the spring 606 is connected to the dial plate, and the other end is connected to the flange ring 602. The dial plate is driven to move by the electric retractor 607. The electric retractor 607 can be connected by contact and pressure and can be separated from the dial plate. The electric retractor 607 is located on the side where the clip bottom plate and the wire tube 601 are pressed together. The electric retractor 607 is installed on the toggle fixing bracket 610, and the toggle fixing bracket 610 is connected to the wire cutting machine.
[0018] Working Principle: The electric retractor 607 drives the paddle to move rightward, compressing the spring 606 to store energy. At this point, the clip base of the clip 605 is lifted from the winding drum 601, and the cut wire extends between the clip base and the winding drum 601. The electric retractor 607 separates from the paddle, and the spring 606 releases energy, driving the clip 605 to press the cut wire tightly between the clip base and the winding drum 601. The winding drum 601 begins to wind the wire. As the electric retractor 607 separates from the paddle, the winding drum 601, flange ring 602, embedded groove 603, rotating shaft 604, clip 605, and spring 606 rotate with the winding drum 601. The electric retractor 607 and the toggle fixing frame 610 remain in their existing state and do not rotate with the winding drum 601. The automatic winding mechanism enters the winding process. This utility model has a simple structure and more reliable and superior performance than traditional methods, making it a new winding technology solution.
