[0027] In this embodiment, in order to achieve the purpose of comprehensively crushing the caked plastic powder, the caked plastic powder is added into the roller 4 through the feed inlet 3. The plastic powder entering the roller 4 will slide towards the bottom of the roller 4 due to its own gravity. At this time, the swinging hammers 15 inside the roller 4 hammer on the caked plastic powder to crush the caked plastic powder. At the same time, the crushed plastic powder is filtered through the roller filter screen 5 on the roller 4, so that the plastic powder meeting the specifications falls out, and the plastic powder not meeting the specifications stays inside the roller 4 and is continuously crushed by the swinging hammers 15 to achieve the purpose of completely crushing the caked plastic powder;

[0028] Among them, in order to prevent the drum filter screen 5 from being blocked when filtering plastic powder, the following technical solution is adopted by this device: The anti-blocking component includes a toothed ring 6, the toothed ring 6 is fixedly sleeved outside the drum 4, a gear 7 is arranged at the top of the toothed ring 6, the toothed ring 6 is engaged with the gear 7, a rotating shaft 8 is inserted inside the gear 7, a rotary brush 9 is fixedly sleeved outside the rotating shaft 8, both ends of the rotating shaft 8 are connected to both side walls of the crushing box 2 through bearings, both ends of the drum 4 are connected to both side walls of the crushing box 2 through bearings. When the drum 4 rotates, it drives the toothed ring 6 to rotate. The rotation of the toothed ring 6 makes the rotating shaft 8 drive the rotary brush 9 to rotate through the gear 7. The rotation of the rotary brush 9 brushes the drum filter screen 5. At the same time, in cooperation with the rotation of the drum 4, the drum filter screen 5 is in full contact with the rotary brush 9, so as to brush the drum filter screen 5 comprehensively, achieving the purpose of preventing the drum filter screen 5 from being blocked;

[0029] Among them, in order to provide power for the swinging of the swing hammers 15, the following technical solution is adopted by this device: A motor 10 is fixedly arranged on one side of the crushing box 2, the output end of the motor 10 is fixedly connected to one end of a transmission shaft 11, the transmission shaft 11 penetrates through one side wall of the crushing box 2 and is connected to one side wall of the crushing box 2 through a bearing, the transmission shaft 11 penetrates through a fixed disk 12 and a fixed frame 13 and is fixedly connected to the fixed disk 12 and the fixed frame 13.

A connecting shaft 14 penetrates through the fixed disk 12 and the fixed frame 13 and is connected to both the fixed disk 12 and the fixed frame 13 through bearings. When the motor 10 is started, the rotation of the motor 10 makes the fixed disk 12 and the fixed frame 13 rotate through the transmission shaft 11. The rotation of the fixed disk 12 and the fixed frame 13 drives the external drum 4 and the connecting shaft 14 inserted inside it to rotate. When the connecting shaft 14 rotates, it swings up the swing hammers 15 and makes the swing hammers 15 move in a circular motion inside the drum 4 to crush the agglomerated plastic powder inside the drum 4.

[0030] The usage process of the present utility model is as follows: When using the present utility model, an external power source is connected, and the motor 10 is started. The rotation of the motor 10 causes the fixed disk 12 and the fixed frame 13 to rotate through the transmission shaft 11. The rotation of the fixed disk 12 and the fixed frame 13 drives the external drum 4 and the connecting shaft 14 inserted therein to rotate. When the connecting shaft 14 rotates, the hammer 15 is swung up, and the hammer 15 moves in a circular motion inside the drum 4. At this time, the caked plastic powder is added into the drum 4 through the feeding port 3. The plastic powder entering the rotating drum 4 will slide towards the bottom of the drum 4 due to its own gravity. At this time, the hammer 15 swinging inside the drum 4 strikes the caked plastic powder to crush the caked plastic powder. At the same time, the crushed plastic powder is filtered through the drum filter screen 5 on the drum 4, so that the plastic powder meeting the specifications falls out, and the plastic powder not meeting the specifications remains inside the drum 4 and is continuously crushed by the hammer 15, achieving the purpose of completely crushing the caked plastic powder. At the same time, for the purpose of preventing the drum filter screen 5 from being blocked by the plastic powder, when the drum 4 rotates, it drives the gear ring 6 to rotate. The rotation of the gear ring 6 causes the rotating shaft 8 to drive the brush 9 to rotate through the gear 7. The rotation of the brush 9 brushes the drum filter screen 5. At the same time, in cooperation with the rotation of the drum 4, the drum filter screen 5 is brought into full contact with the brush 9, so as to brush the drum filter screen 5 comprehensively, achieving the purpose of preventing the drum filter screen 5 from being blocked.

[0031] The above is only the preferred embodiment of the present utility model.
