[0017] The leather punching equipment of the utility model will be described in more detail below in combination with the drawings and through specific embodiments.
[0018] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0019] Referring to Figures 1-4The leather punching device of the embodiment is characterized in that before cutting, a roller is used to roll the leather, so that the leather is laid flat on the workbench, thereby improving the cutting accuracy. The device mainly comprises a frame 1, a cutting mechanism and a control mechanism arranged on the frame 1. The cutting mechanism comprises an electric push rod 4, a cutting knife 5 and a pressing rod 6. The electric push rod 4 is installed on a door-shaped frame above the frame 1, and the bottom of the door-shaped frame is detachably installed on the frame of the frame 1. The cutting knife 5 is detachably installed on the free end of the electric push rod 4, and the cutting knife is controlled to move up and down by the electric push rod to cut the leather. The pressing rod 6 is installed on both sides of the cutting knife 5 through a compression spring 7, and the bottom surface of the pressing rod 6 is lower than the cutting knife 5, so as to press and fix the cutting area of the leather before the cutting knife contacts the leather, thereby ensuring the cutting accuracy.
