[0003] In the production process of insulation boards, a lot of scraps will be generated. The scraps generally need to be recycled and re-granulated for use. Before granulating the scraps, the XPS scraps need to be crushed. However, the existing crushers have some shortcomings when crushing the scraps: the crushed scraps are easy to splash out, causing material waste. When the crushed scraps are added to the granulator, the flow of the debris leaking into the granulator cannot be controlled. Therefore, improvements are needed. Utility Model Content

[0020] like Figure 1 and 3 The lifting crushing device 6 includes an electric push rod 7, a connecting frame 8 is provided at the output end of the electric push rod 7, an end cover 9 is provided at the lower end of the connecting frame 8, the end cover 9 can cover the hopper 4, a motor 10 is provided on the end cover 9, and a crushing tooth 11 is provided at the output end of the motor 10, a bottom plate 15 is provided at the lower end of the crushing tooth 11, and a brush 16 is provided at the lower end of the bottom plate 15. When the end cover 9 covers the hopper 4, the brush 16 is tightly attached to the upper end surface of the fixed plate 12, and the brush 16 can clean the fixed plate 12 to prevent debris from accumulating on the fixed plate 12. The hopper 4 can be sealed by the end cover 9, and the crushing tooth 11 can crush the scraps of XPS insulation board in the hopper 4 to prevent debris from splashing out.

[0021] like Figure 1-2 The flow control device 5 includes a fixed plate 12, which is located at the junction of the discharge barrel 3 and the hopper 4.
