In the EPS production line, the foam needs to be processed and formed, which requires the use of an EPS milling device. The main function of the EPS milling device is to mill the two sides of the foam core material flat or process it to the required thickness. The current structure of the EPS milling device is as follows Figure 1 and 2 As shown, multiple existing milling cutters 5 are installed on the existing milling cutter shaft 4 in parallel and at intervals, and the multiple existing milling cutters 5 are evenly distributed around the circumference of the existing milling cutter shaft 4. The existing milling cutters 5 are all long strip structures and are arranged along the axial direction of the existing milling cutter shaft 4. This device has the following problems: 1) The installation and assembly are relatively complicated; 2) Due to the gaps between the multiple milling cutters, there will be linear residues in the milled plane; 3) Due to the assembly gap of the shaft hole and the size deviation of the milling cutter blade, the milling is often not smooth.
