when the torsion bearing 202 rotates to a certain degree, the torsion bearing 202 is rotatably connected with the torsion spring 203, the torsion spring 203 keeps the deformed state unchanged, when the fan 201 stops rotating, the torsion spring 203 drives the linkage structure 204 to rotate under the action of elastic force, because the linkage structure 204 is in threaded connection with the reciprocating screw 205, the linkage structure 204 drives the reciprocating screw 205 to perform one reciprocating motion when rotating, when the reciprocating screw 205 performs reciprocating motion, the push plate 206 is pushed to move from right to left in the melting chamber 104, the torsion spring 203 is restored when the reciprocating screw 205 moves to the leftmost side, so that the reciprocating screw 205 stops, the push plate 206 plays a role in cleaning and scraping the inner wall of the melting chamber 104 in the moving process, when the push plate 206 moves to the position of the electromagnet 208, the electromagnet 208 is triggered to be powered off, so that the electromagnet 208 loses magnetism, the electromagnet 208 moves downwards under the action of gravity, the inner wall of the left side of the melting chamber 104 and the left side of the push plate 206 are cleaned, pigments on the push plate 206 are cleaned, when the reciprocating screw 205 operates again, the reciprocating screw 206 drives the push plate 206 to move from left to right, at the moment, the raw materials in the drying chamber 103 lose the blowing force of the fan 201 and fall onto the baffle 8, and the push plate 206 plays a certain supporting role on the baffle 8 in the process of moving towards right, so that the baffle plate 8 can not be inclined under the action of gravity, when the push plate 206 moves to a position not in contact with the baffle plate 8, the raw materials on the baffle plate 8 fall into the melting chamber 104, when all the raw materials on the baffle plate 8 fall into the melting chamber 104, and simultaneously when the push plate 206 moves rightwards, the baffle plate 8 is reset under the action of the elastic force of the elastic rope 7, at the moment, the push plate 206 is driven by the reciprocating screw rod 205 to move leftwards, so that the push plate 206 is reset, when the second electromagnet 208 moves downwards, the support rod 301 is driven to move downwards, the support rod 301 penetrates through the inner wall of the spray head 303, when the push plate 206 moves rightwards, the second electromagnet 208 recovers magnetism, and
