Description

[0002] EVA foam, full name ethylene-vinyl acetate copolymer foam, is a polymer composite material with excellent properties.

[0003] The structure of the punching device can refer to the utility model disclosed in the authorization announcement number "CN220313540U" which discloses "a punching device for EVA foam". The double-station setting facilitates punching of the cut and formed EVA foam, which solves the problem that the existing EVA foam punching device needs to repeatedly put the EVA foam into and take it out of the punching device when punching the cut and formed EVA foam, and needs to stop the punching device when taking out the punched EVA foam, so that the cut and formed EVA foam is punched continuously, thereby reducing the speed of the EVA foam punching device.

[0004] However, when the above device punches the EVA foam, since the EVA foam is placed in a frame and there is no good limiting and fixing measure, the EVA foam will be displaced to a certain extent during punching, resulting in the offset of the punching position. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an EVA foam punching device with a positioning structure.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
