[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model, but not to limit the utility model.

[0025] Reference Figure 1-4 The utility model provides an EVA sheet punching machine, including a base 1, a slide rail 2 arranged above the base 1, and a pressing assembly 3 slidably connected to the slide rail 2. The pressing assembly 3 includes a lifting member 31, a cutting die 32 and a telescopic rod 33. The cutting die 32 is arranged below the lifting member 31. The cutting die 32 can be detachably connected to the lifting member 31. The connection method includes but is not limited to magnetic connection, clamping, etc. (not shown in the figure). The cutting die 32 is composed of a plurality of blade rings 321 arranged along the target punching shape and arranged equidistantly, which can be selected as a rectangle, a square, etc. The telescopic rod 33 is arranged in a single blade ring 321. The telescopic rod 33 includes an outer sleeve 331, an inner sleeve 332 and a spring member. One end of the outer sleeve 331 is detachably connected to the lifting member 31 by a screw, and the position of the telescopic rod 33 can be adjusted according to the number of blade rings 321. The outer sleeve 331 is sleeved on the inner sleeve 332, and the spring member is arranged in the outer sleeve 331 and connects the outer sleeve 331 and the inner sleeve 332. The spring member makes the inner sleeve 332 extend from the outer sleeve 331 without external force. The end of the inner sleeve 332 is connected with a buffer head 333. The material of the buffer head 333 can be rubber material or sponge material. The use of rubber material can not only play a buffering role when the telescopic rod 33 contacts the EVA sheet, but also increase the friction between the telescopic rod 33 and the EVA sheet. The lifting member 31 descends to shrink the telescopic rod 33. When the cutting die 32 moves to contact the base 1, the telescopic rod 33 is squeezed and shrunk in the blade ring 321. A plurality of strip grooves 11 are arranged in parallel and staggered horizontally and vertically. The strip grooves 11 form a plurality of platforms no larger than the blade ring 321 above the base 1, which reserve space for the blade ring 321 to descend. Slide seats are provided on both sides of the lifting member 31 . The slide seats are embedded in the slide rail 2 and meshed with the slide rail 2 through a screw assembly, and the screw assembly is driven to rotate to move the lifting member 31 .

[0026] Working principle: When working, the EVA sheet is placed on the base 1, and then the pressing component 3 is started to move and rise and fall in sequence to realize the cutting and punching of the EVA sheet. When the pressing component 3 descends, the telescopic rod 33 pre-contacts the EVA material and fixes it, and then the cutting die 32 is continuously descended to cut and punch the EVA sheet; when the cutting and punching is completed, the telescopic rod 33 finally leaves the EVA material to realize the separation of the cutting and punching die.

[0027] It should be understood that the embodiments disclosed in the present invention are not limited to the specific processing steps or materials disclosed herein, but should be extended to equivalent substitutions of such features understood by ordinary technicians in the relevant field. It should also be understood that the terms used herein are only used for the purpose of describing specific embodiments and are not meant to be limiting.

[0028] The "embodiment" mentioned in the specification means that the specific features or characteristics described in conjunction with the embodiment are included in at least one embodiment of the utility model. Therefore, the phrases or "embodiment" appearing in various places throughout the specification do not necessarily refer to the same embodiment.

[0029] In addition, the described features or characteristics may be combined in one or more embodiments in any other suitable manner. In the above description, some specific details, such as thickness, quantity, etc., are provided to provide a comprehensive understanding of the embodiments of the utility model. However, those skilled in the relevant art will understand that the utility model can be implemented without one or more of the above specific details or can also be implemented using other methods, components, materials, etc.
