Detailed Description of the Preferred Embodiments

[0019] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] Such as Figures 1-4As shown in the figure, the utility model includes a lower plate 1, on which there are four vertical rods 11, and the upper ends of the vertical rods 11 are jointly connected to an upper plate 12; the lower plate 1 serves as a basic support platform, stably carrying the core components of the entire device. The four vertical rods 11 arranged on it not only enhance the structural stability but also cleverly act as pillars connecting the upper plate 12, enabling the upper plate 12 to be suspended smoothly above the working area;

[0022] A cylinder 3 is installed on the upper plate 12. A push plate 31 is provided at the output end of the cylinder 3, and a first cutter 32 and two second cutters 33 are provided on the push plate 31; through the telescopic movement of the cylinder 3, the push plate 31 drives the first cutter 32 and the two second cutters 33 to descend, stamping and cutting the material placed on the lower plate 1. By using the punching of one first cutter 32 and two second cutters 33, the second cutter 33 can punch the rubber sheet 22 remaining after the punching of the first cutter 32 again, thus avoiding waste of materials and improving work efficiency at the same time.

[0023] Preferably, four grooves are formed on the lower plate 1. Rotating shafts 21 are respectively arranged in the grooves. A rubber sheet 22 is arranged between the two rotating shafts 21. One end of the rotating shaft 21 is provided with a motor 2, and the motor 2 is installed on the lower plate 1; four fixing plates 16 are arranged on the lower plate 1. The fixing plates 16 extend out of the grooves and limit the rotating shafts 21 in the grooves;

[0024] Through the arrangement of the fixing plates 16, the stable operation of the rotating shafts 21 in the grooves can be ensured. At the same time, by removing the fixing plates 16, the rubber sheet 22 can be replaced.

[0025] Preferably, a first mold 13 and two second molds 15 are arranged on the lower plate 1. The position of the first mold 13 corresponds to that of the first cutter 32, and the position of the second mold 15 corresponds to that of the second cutter 33;
