Through the arrangement of the box body 1, the extruding mechanism 4, the nozzle 9, the water pump 10 and the motor 23 and other structures, the cut particles can be flushed into the inside of the box body 1 by spraying water, which solves the problem that the particles are easily adhered to the cutting knife 7 and adhere to the particles after being cut again as they move downward, thereby improving the quality of the sheath material after being cut, and the sprayed water can cool the cutting knife 7 to avoid the particles being easily adhered after it heats up, and at the same time, the water can cool down when it falls, thereby reducing its overall temperature and improving the cooling efficiency of the particles.

[0031] The cleaning assembly includes a fixed plate 18 fixedly connected to the top of the support plate 6, and a number of telescopic rods 19 are fixedly connected to one side of the fixed plate 18. The outer surface of the telescopic rod 19 is provided with a spring 20.
