[0015] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] Such as Figures 1 to 4A punching machine with a limiting mechanism is shown, including: a base 1, a support frame 2, a rotating motor 7, a rotating shaft 6, a runner 9, a punching rod 10, and a limiting device. The support frame 2 is fixed on the base 1. There is a top plate 3 at the top of the support frame 2. The rotating motor 7 is fixed on the top plate 3. There is a bearing seat 4 on the top plate 3. There is a bearing 5 inside the bearing seat 4. There is a rotating shaft 6 fixed to the inner ring of the bearing 5 at the center of the bearing 5. The end of the rotating shaft 6 is shaft-connected to the output shaft of the rotating motor 7. The rotating motor 7 drives the rotating shaft 6 installed on the top plate 3 to rotate. There is a short shaft 8 at the front end of the rotating shaft 6. The short shaft 8 is eccentrically arranged at the edge of the end of the rotating shaft 6. The short shaft 8 passes through the center of the runner 9 and is fixedly connected to it. There is a horizontally arranged support plate 12 in the middle of the support frame 2. There is a hollow tube 11 at the front end of the support plate 12. The punching rod 10 passes through the hollow tube 11. There is a pressing plate 13 at the upper end of the punching rod 10. The pressing plate 13 is located directly below the runner 9. There is a spring 14 on the punching rod 10. The upper and lower ends of the spring 14 are respectively fixed to the lower side of the pressing plate 13 and the upper end of the hollow tube 11. There is a detachable punch head 21 at the lower end of the punching rod 10. The limiting device is located directly below the punch head 21. The limiting device is fixed on the base 1. The sheet material advances along the limiting device and is punched by the punch head 21.

[0017] The rotating motor 7 can drive the runner 9 to rotate. The rotation of the runner 9 can periodically drive the pressing plate 13 to press down, so as to realize the punching of the punch head 21. The spring 14 can pull the punching rod 10 upward after the punch head 21 completes punching.

[0018] The limiting device includes two vertical plates 15, a cover plate 16, a support plate 17, and a conveyor belt 19. The vertical plates 15 are vertically fixed on the base 1. The cover plate 16 is fixed to the upper ends of the two vertical plates 15. The support plate 17 is fixed to the middle of the vertical plates 15. There is a slot hole 25 in the middle of the support plate 17. There are two horizontal shafts 27, front and back, at the lower part of the vertical plates 15. One of the horizontal shafts 27 is driven to rotate by a motor 20. There is a gear 26 on each side of the horizontal shaft 27. The conveyor belt 19 is a rack conveyor belt. The two conveyor belts 19 are respectively engaged with the gears 26 on both sides. The top of the conveyor belt 19 is higher than the support plate 17. There is a chute 24 below the conveyor belt 19. The chute 24 is located in the middle of the two conveyor belts 19. There is a perforation 22 in the middle position of the cover plate 16. The punch head 21 passes through the perforation 22. The chute 24 is located directly below the punch head 21. There is a pulling plate 23 at the front end of the chute 24.

[0019] When the limiting device is working, the sheet material is placed in the reserved channel 18 between the support plate 17 and the cover plate 16. The sheet material is driven forward by the two conveyor belts 19. When it moves directly below the perforation 22, the rotating motor 7 is started, and the punch head 21 presses down to complete punching. The waste after punching falls into the chute 24. Since the conveyor belt is slightly higher than the support plate 17, when punching, the sheet material will press down. Therefore, a certain margin is set for the conveyor belt 19 to ensure that when punching, the sheet material is supported by the support plate 17, and when the conveyor belt 19 runs, the sheet material is separated from the support plate 17.

[0020] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
