[0002] A button sewing machine is an automated device that rivets buttons onto garments, such as labels, tags, and caps. The most commonly used buttons are disc-shaped buttons with two or four holes (also known as flat buttons). By replacing various specialized accessories, a single button sewing machine can sew various types of buttons, including shank buttons, metal buttons, snap buttons, shank buttons, and official buttons.

[0003] Existing button sewing machines primarily consist of a feeding device and a button sewing device. The button sewing device comprises a die base and a punch rod. The die base houses the lower button, while the punch rod houses the upper button. The punch rod then presses the upper and lower buttons together after striking down. Currently, there are numerous types of buttons on the market, with varying specifications. Therefore, during the stamping process, the punch end and length of the punch rod must be adjusted to accommodate different buttons. However, the punch rod adjustment in existing button sewing machines is not convenient. Utility Model Content

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] This embodiment discloses an adjustable punch rod of a button sewing machine, such as Figure 1-6 As shown, it includes a frame, a punch rod 1 arranged on the frame and a driving device 2 for driving the punch rod 1. The punch rod 1 includes a first punch rod 101, a second punch rod 102 and an adjusting component 4. One end of the first punch rod 101 is provided with a connecting ear 3, and the other end is connected to the driving device 2; the adjusting component 4 is rotatably connected to the connecting ear 3, and a threaded rod 401 and a locking nut 402 are provided on the adjusting component 4. One end of the second punch rod 102 is provided with a threaded hole 5, and the other end is provided with an assembly hole 6. The threaded hole 5 is threadedly connected to the threaded rod 401 and axially fixed by the locking nut 402; a punch component 7 is installed in the assembly hole 6. Through the above structure, this embodiment allows the first punch rod 101 and the second punch rod 102 to be adjusted by setting the adjusting component 4, thereby realizing the adjustment of the length of the punch rod 1, and has good versatility when used for buttons of different specifications. Reference Figure 6 When adjusting, you only need to loosen the locking nut 402, then rotate the second punch rod 102 to move the second punch rod 102 upward to reduce the length, or directly rotate the second punch rod 102 downward to increase the length. After the adjustment is completed, re-tighten the locking nut 402. The structure is very simple and easy to adjust.

[0025] Furthermore, a notch 8 is provided at one end of the adjusting component 4 connected to the connecting ear 3, and both the notch 8 and the connecting ear 3 are provided with a through hole, and a rotating pin 9 is provided in the through hole. At the same time, a top screw hole A10 is provided on the side wall of the connecting ear 3, and the rotating pin 9 is fixed by screwing a top screw into the top screw hole A10. Through the above structure, the adjusting component 4 and the connecting ear 3 can be rotated together through the rotating pin 9, and the rotating pin 9 and the connecting ear 3 are relatively fixed by screwing a top screw (the top screw is not shown in the figure) into the top screw hole A10, ensuring that the rotating pin 9 will not loosen when rotating in cooperation with the adjusting component 4, maintaining a stable and reliable connection. At the same time, the top screw connection method is adopted, and the whole is easy to disassemble after unscrewing the top screw, so that the adjusting component 4 is detachable and replaceable, which is convenient for inspection and maintenance.

[0026] Further, refer to Figure 3 and Figure 5 The driving device 2 includes a driving motor 201, a power disk 202 is connected to the output shaft of the driving motor 201, a crank component 203 is fixedly provided on the power disk 202, and a connecting shaft 12 is provided at the end of the crank component 203 near the outer side of the power disk 202, which passes through the power disk 202, and the first punch 101 is rotatably connected to the connecting shaft 12. Through the above structure, the crank component 203 is connected to the first punch 101 through the connecting shaft 12, which can drive the first punch 101 to move up and down. The setting can balance the mass of the power disk 202 to a certain extent, and alleviate the mechanical vibration generated by the eccentric movement of the first punch 101 driven by the crank component 203. At the same time, the power disk 202 and the crank component 203 form a whole. Compared with using the crank component 203 alone, the power disk 202 can alleviate vibration to a certain extent; and compared with using the power disk 202 alone, the crank component 203 can increase the connection strength, ensuring that the connection structure of the punch 1 is stable when frequently performing reciprocating punching.

[0027] Furthermore, a top screw hole B13 is provided on the side wall of the assembly hole 6 of this embodiment, and a top screw (top screw not shown in the figure) is screwed into the top screw hole B13 to fix the punch component 7. Further preferably, two top screw holes B13 are symmetrically provided, and the punch component 7 has a variety of different specifications, mainly because the punching ends of the punch components 7 of different specifications are different. Through the above structure, the punch component 7 can be easily disassembled and assembled, and it is convenient to replace the punch components 7 with different punching ends. The structure is simple and the versatility is strong. In addition, the two symmetrically provided top screw holes B13 can also be more convenient to fix and adjust, and can be stably connected even when the punch component 7 is frequently affected by the external force of stamping.

[0028] Furthermore, a limiting sleeve 14 is provided on the frame, and the second punch rod 102 passes through the limiting sleeve 14 and slides with the limiting sleeve 14. By setting the limiting sleeve 14 to constrain the position of the second punch rod 102, the accuracy of the punching position can be effectively guaranteed.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
