The working principle is as follows: the polypropylene raw material is poured onto the spiral material guide plate 204, then the electromagnet 201 is powered on intermittently, so that the electromagnet 201 can generate magnetism intermittently, when the electromagnet 201 obtains magnetism, magnetic force is generated between the electromagnet 201 and the iron plate 203, the iron plate 203 is pulled downwards, when the electromagnet 201 is powered off and loses magnetism, the iron plate 203 moves upwards, so that the iron plate 203 continuously moves up and down, the spiral material guide plate 204 fixedly connected with the iron plate 203 can also continuously move up and down, the polypropylene raw material poured onto the spiral material guide plate 204 spirally slides down along the spiral material guide plate 204, finally falls onto the screen 209 for screening, small particles fall into a collecting box arranged below the screen 209, large particles stay on the screen 209, then the screen 209 and the spiral material guide plate 204 are detachable, the screen 209 can be taken off from the spiral material guide plate 204 through a manipulator, the raw material in the screen 209 is poured into the crushing component, then the screen 209 is installed on the spiral material guide plate 204, and meanwhile, the raw material collected by the manipulator can be poured into the crushing component. In the process that the spiral material guide plate 204 moves up and down along with the iron plate 203, because the material guide gear 206 is meshed with the rack 205, the material guide gear 206 rolls up and down along the rack 205, the material pushing screw rod 208 fixedly mounted on one material guide gear 206 rotates inside the material storage barrel 1, so that the crushed polypropylene raw material entering the material storage barrel 1 is sent out from the material storage barrel 1, the other material guide gear 206 is fixedly connected with the extrusion roller 207, and the material guide gear 206 fixedly connected with the extrusion roller 207 drives the extrusion roller 207 to rotate, so that when the crushed raw material on the spiral material guide plate 204 is met, preliminary crushing can be performed, and subsequent crushing is facilitated.
When the raw material is added into the second mounting frame 305 in the crushing assembly, the motor 316 is started at the same time, the fifth gear 315 fixedly arranged on the output shaft of the motor 316 rotates along with the motor 316, the fifth gear 315 is meshed with the fourth gear 314, so that the fourth gear 314 rotates on the circular plate 301 along with the fifth gear 315; because the fourth gear 314 is fixedly connected with the hollow column 312, the blade 327 is positioned inside the hollow column 312, and the blade 327 is in sliding fit with the inner wall of the hollow column 312, and because the baffle 3122 is arranged inside the hollow column 312, the blade 327 and the baffle 3122 divide the inside of the hollow column 312 into four chambers, a central connecting line of two symmetrically arranged fluid holes 3121 on the hollow column 312 is not overlapped with a central connecting line of the baffle 3122, so that the two fluid holes 3121 are respectively positioned right above the two independent chambers, the fluid holes 3121 are not arranged above the other two independent chambers, the two independent chambers with the fluid holes 3121 right above contain hydraulic oil, and the two independent chambers without the fluid holes 3121 right above contain air. When the fourth gear 314 rotates, the hollow column 312 also rotates, and meanwhile, the independent part of hydraulic oil is used for pushing the blade 327 to rotate, so that the connecting shaft 311 fixedly connected with the blade 327 rotates, the third gear 310 is fixedly connected with the connecting shaft 311, so that the third gear 310 also rotates inside the shell 302, so that the hollow gear 303 meshed with the third gear 310 rotates, the second mounting rack 305 fixedly mounted at the lower end of the hollow gear 303 drives the three screw rods 306 to rotate along with the hollow gear 303, the second mounting rack 305 is in sliding fit with the inner wall of the shell 302, when the screw rods 306 rotate, falling raw materials are stirred and separated, and when the screw rods 306 revolve along with the second mounting rack 305, the first gear 307 fixedly mounted on the screw rods 306 rotates along with the second gear 308, so that the screw rods 306 rotate on the second mounting rack 305, so that the screw rods 306 have two rotation and revolution modes, and thus the rotation modes are beneficial to accelerating the stirring and separation of the raw materials. The first mounting frame 304 fixedly mounted on the housing 302 mainly serves to mount the second gear 308, the second guide cylinder 309 fixedly mounted on the second mounting frame 305 is rotatably mounted in the center of the first mounting frame 304, and the guide cylinder 309 mainly serves to position the second mounting frame 305, so that the central axes of the second gear 308, the hollow gear 303, the second mounting frame 305 and the guide cylinder 309 coincide with the central axis of the upper end opening of the storage tank 1.
When the gear five 315 rotates, the gear six 317 is also driven by the gear five 315 to rotate, the gear six 317 drives the gear seven 318 to rotate together, the gear seven 318 drives the upper suction cup 322 to rotate, if the raw material poured into the mounting bracket two 305 can be smoothly stirred and crushed by the screw rod 306, the upper suction cup 322 and the lower suction cup 323 in this state are connected together, so that the upper suction cup 322 rotates to rotate the lower suction cup 323 together, the rotating lower suction cup 323 drives the central shaft 324 to rotate on the circular plate 301, so that the mounting block 325 fixedly mounted on the central shaft 324 rotates, the mounting block 325 drives the cover plate two 326 to rotate out from the middle of the circular plate 301, the circular hole 3261 on the cover plate two 326 passes through the opening of the storage vat 1, so that the rest part of the cover plate two 326 gradually rotates to the upper opening of the storage vat 1 and is located between the circular plates 301, so that the raw material can be stopped and stirred and separated by the screw rod 306, and when the two 326 rotates to leave the upper opening of the storage vat 1, the separated raw material just falls into the upper opening of the circular plate 301, and the raw material can pass through the screw rod 208 and can be discharged out of the storage vat 1.
When the raw materials poured into the second mounting frame 305 are agglomerated or bonded together, the resistance to the stirring and crushing process of the screw rod 306 is greater than the resistance to the screw rod 306 during smooth stirring and crushing, and as the resistance to the screw rod 306 increases, the rotational resistance of the second mounting frame 305 and the hollow gear 303 also increases, which results in the increase of the rotational resistance of the third gear 310, the rotational resistance of the connecting shaft 311 increases, the blades 327 are fixedly mounted on the connecting shaft 311, so the rotational resistance of the blades 327 increases, the output torque of the motor 316 does not change, the rotational speed of the fourth gear 314 does not change, the rotational speed of the hollow column 312 fixedly connected with the fourth gear 314 does not change, and the rotational resistance of the blades 327 increases, so the chamber filled with hydraulic oil in the hollow column 312 increases, and at this time, the hydraulic oil in the connecting pipe 319 flows into the chamber filled with hydraulic oil from the connecting pipe 319 through the fluid holes 3121. Meanwhile, as the hydraulic oil in the connecting pipe 319 enters the hollow column 312, the pressure inside the connecting pipe 319 is reduced, the external atmospheric pressure strongly pushes the straight rod 320 to the inside of the connecting pipe 319, the straight rod 320 slides to the inside of the connecting pipe 319, and simultaneously the upper sucker 322 and the gear seven 318 move together with the straight rod 320, so that the upper sucker 322 is separated from the lower sucker 323, when the resistance of the spiral rod 306 in stirring and crushing the raw materials is reduced, the resistance of the gear three 310 is reduced, the elastic force of the compressed spring 321 is greater than the force applied to the straight rod 320 by the external atmospheric pressure, the spring 321 pushes the upper sucker 322 to one side close to the lower sucker 323, the upper sucker 322 is in contact with the lower sucker 323, and simultaneously the straight rod 320 slides out of the connecting pipe 319, so that when the rotating gear six 317 drives the gear seven 318 to rotate, the lower sucker 323 rotates along with the upper sucker 322, the mounting block 325 drives the cover plate two 326 to rotate, so that the stirred and crushed raw materials enter the storage barrel 1, and the material supply is completed.
