Specifically, during the working process, the feed roller 3 and the granulating roller 2 form a feed gap, the feed roller 3 rotates clockwise, and the granulating roller 2 rotates counterclockwise. After the raw materials are added into the roller cover 1, the raw materials are extruded by the rotation of the feed roller 3 and the granulating roller 2 and then smoothly enter the roller cover 1 through the feed gap. The fixed knife assembly abuts against the granulating roller 2, and when the raw materials enter the fixed knife assembly through the feed gap, the granulating roller 2 drives the raw materials to rub against the fixed knife assembly. During the rubbing process, the fixed knife assembly cooperates with the granulating roller 2 to realize the granulating operation. During the above granulating process, the fixed knife assembly is worn out due to long-term abutment for granulating operation and needs to be replaced. At this time, the base stops running, then the traveling module 4 is started to move the base 5 to the outside of the roller cover 1, so that the cutter head 7 is separated from the working area and is located in the empty area outside the roller cover 1, so that the maintenance personnel have a larger working space, then the locking device is released, the damaged cutter head 7 is removed from the knife seat 6, and then the new cutter head 7 is placed on the knife seat 6. During the placement process, the locking device fixes the cutter head 7 on the knife seat 6. After the replacement of the cutter head 7 is completed, the traveling module 4 is started again to move the base 5 to the inside of the roller cover 1, and when the base 5 drives the cutter head 7 to move to the granulating working area and is fixed, then the cutter head 7 is adjusted to a suitable working size by the adjusting module.
