As shown in fig. 3, in the present embodiment, a limiting end plate 505 is fixedly connected to an upper end of the arc-shaped plate 502, and the upper end of the limiting end plate 505 is higher than the guide rail 504, so that the guide wheel 608 is prevented from falling off from the guide rail 504.
Before plastic particles are screened, a first material gate 209 at one end of a coarse screen cylinder 201 is opened, then the open end of a screening cylinder 2 is driven by a hydraulic cylinder 301 to incline upwards, then the plastic particles are added into the coarse screen cylinder 201 through a feeding mechanism, and the first material gate 209 is installed again and reset; the hydraulic cylinder 301 is controlled to stretch back and forth in a reciprocating mode, the hydraulic cylinder 301 drives the first rotating shaft 306 to rotate in a circulating forward and reverse mode through the connecting rod 302, and therefore the support frame 5 is used for driving the screening drum 2 to rotate in a circulating forward and reverse mode; when the support frame 5 rotates, the lifting component 4 on one side of the support frame is driven to rotate together, the second gear 404 is meshed with and rotates around the first gear 304 so as to drive the cylindrical cam 402 to rotate in a circulating manner, the lifting rod 405 on one side of the cylindrical cam 402 moves up and down in a circulating manner under the action of the deflector rod 406 and the cylindrical cam 402, and the screening cylinder 2 is driven to move up and down; in addition, when the screening cylinder 2 moves up and down, the linkage assembly 6 at the right end drives the third driving gear 602 to rotate under the action of the second internal gear ring 503, the third driving gear 602 drives the third driving bevel gear 604 to rotate through the second rotating shaft 603, the third driving bevel gear 604 drives the third driven bevel gear 605 and the third rotating shaft 606 to rotate, so as to drive the coarse screening cylinder 201 to rotate, the first internal gear ring 205 outside the coarse screening cylinder 201 drives the fine screening cylinder 202 to rotate reversely with the coarse screening cylinder 201 through the tying of the planet gear 208, and thus, the screening cylinder 2 performs up-and-down swinging, action swinging and rotation compound movement of the coarse screening cylinder 201 and the fine screening cylinder 202, so that the screening effect of the screening device is greatly ensured; in addition, when the screening cylinder 2 performs the compound movement, the spring 102 at the lower part of the base 1 enables the screening cylinder 2 to perform disordered vibration on the base 1, thereby further enhancing the screening effect of the screening device. After the plastic particles are screened, the hydraulic cylinder 301 is used for driving the left side of the screening barrel 2 to incline downwards, the material guide plate 213 is drawn out and fixed, then the first material door 209 is opened to pour out the coarse particles in the coarse screening barrel, the second material door 210 is opened to pour out the medium particles in the fine screening barrel 202, and the third material door 211 is opened to pour out the fine particles in the outer barrel 203.
The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the present invention as defined in the accompanying claims.
