[0025] The screening device includes a conveyor belt 14, a carriage 4, a fixed frame 1 and a driving device. Two driving wheels 6 are installed for rotation inside the carriage 4. The support belt 143 is sleeved on the two driving wheels 6. A second motor 16 for driving the driving wheel 6 to rotate is fixed on the carriage 4. The second motor 16 drives the driving wheel 6 to rotate. The driving wheel 6 rotates to drive the support belt 143 to transmit on the driving wheel 6. A support plate 8 is provided between the two driving wheels 6. The support plate 8 is fixed on the carriage 4. The support plate 8 is used to support the conveyor belt 14 to ensure that the conveyor belt 1 4 will not be deformed under the pressure of the pressure wheel 5. The surface of the conveyor belt 14 is provided with a plurality of reflow grooves arranged along the conveying direction thereof. The plurality of reflow grooves are arranged at intervals. During the conveying process of the conveyor belt 14, when the material falls on the upper part of the conveyor belt 14, part of the material will fall into the reflow groove. A reflow belt 142 is provided inside each reflow groove. The conveying direction of the reflow belt 142 is opposite to that of the conveying direction of the conveyor belt 14. The conveyor belt 14 pushes most of the material to move in the conveying direction. The reflow belt 142 in the reflow groove carries The conveyor belt 14 includes a support belt 143, and a plurality of convex strips 141 are arranged on the surface of the support belt 143. The convex strips 141 are arranged at intervals, and the upper surface of the convex strips 141 is convex. The reflux groove is arranged between two adjacent convex strips 141. The reflux belt 142 is arranged at the bottom of the reflux groove. The width of the convex strip 141 is wider than that of the reflux groove. Therefore, most of the materials will move with the convex strips 141, and some of the materials will fall into the reflux groove. A connecting rod 18 is rotatably installed inside the slide 4, and the clamping wheel 5 is fixedly sleeved on the connecting rod 18. A driving device for driving the connecting rod 18 to rotate is fixed on the slide 4. The driving device in this embodiment is a first motor 15 fixed on the slide 4. The first motor 15 drives the connecting rod 18 to rotate. When the connecting rod 18 rotates, it will simultaneously drive multiple clamping wheels 5 to rotate together. Teeth are provided on the clamping wheel 5 and the return belt 142. The teeth on the return belt 142 are soft teeth that can be slightly deformed, such as rubber.

[0026] The slide 4 is installed inside the fixed frame 1, and the conveyor belt 14 is installed inside the slide 4. The slide 4 can reciprocate up and down inside the fixed frame 1. The up and down reciprocating vibration of the slide 4 forms the vibration of the slide 4 and the conveyor belt 14 inside the slide 4. During the conveying process of the conveyor belt 14, the weight of plastic is light and the weight of metal is heavy. Therefore, during the up and down vibration process of the conveyor belt 14, the metal will fall to the lower layer, and the broken plastic will be arranged on the upper layer of the metal. The metal falls into the reflow trough and is transported through the reflow belt 142. The conveying direction of the conveyor belt 14 is opposite to the conveying direction of the reflow belt 142, so it is only necessary to collect the reflow belt 14 at both ends. The crushed plastic and metal can be collected. A groove with an upper opening is provided on the fixed frame 1, and a clearance space 19 with an opening toward the bottom is provided on both side walls of the groove. The slide 4 is U-shaped, and the side panels on both sides of the slide 4 extend to the inside of the clearance space 19. A slide rod 11 is fixed to the lower end of the slide 4, and a slide hole is provided at the bottom of the groove. The slide rod 11 can slide in the slide hole. The cooperation of the slide rod 11 and the slide groove is used for guiding the slide 4. The slide 4 can move up and down in the groove, and during the movement, the upper end of the side panel of the slide 4 is always arranged in the clearance space 19, and the side panel and the clearance space 19 are in a sealed state, and the material will not enter the inside of the clearance space 19.

[0027] Multiple clamping wheels 5 are rotatably installed inside the slide 4. The clamping wheels 5 are in contact with the reflow belt 142. The clamping wheels 5 can drive the reflow belt 142 to rotate. During the rotation, the clamping wheels 5 can drive the reflow belt 142 to convey. The reflow belt 142 drives the material inside the reflow trough to move, and the moving direction is opposite to the conveying direction of the conveyor belt 14.

[0028] A first discharge port 2 and a second discharge port 13 are provided inside the fixing frame 1, and shells 7 for sealing the first discharge port 2 and the second discharge port 13 are provided on both sides of the fixing frame 1. The first discharge port 2 and the second discharge port 13 are respectively arranged at two ends of a conveyor belt 14, and the two ends of the conveyor belt 14 can discharge crushed plastic and metal respectively. The two materials fall into the first discharge port 2 and the second discharge port 13 respectively, and the staff can collect the materials at the outlet of the discharge port.

[0029] Embodiment 2 like Figure 1-Figure 7As shown, based on the first embodiment, this embodiment provides another waste plastic parts recycling device that links the driving mechanism of the reflow belt 142 and the vibration of the slide 4, and the specific implementation method is as follows: there are two connecting rods 18, and the connecting rods 18 are rotatably installed on the side walls of the slide 4 through the support columns 17, and the connecting rod 3 is eccentrically rotatably installed between any two adjacent clamping wheels 5. The connecting rod 3 passes through the bottom of the slide 4 and is rotatably installed on the fixed frame 1. When the first motor 15 drives the connecting rod 18 to rotate, the connecting rod 3 connected between the two clamping wheels 5 will move up and down, driving the slide 4 to move up and down, thereby linking the driving mechanism of the reflow belt 142 and the vibration of the slide 4.

[0030] Working principle: the material to be crushed enters from the upper end feed port 12 of the feed shell 10, and is crushed by the crushing roller 9. There are metal scraps in the material after crushing. When the crushed material falls on the surface of the conveyor belt 14, it is conveyed by the conveyor belt 14. During the conveying process, the slide 4 drives the conveyor belt 14 to vibrate up and down. When the conveyor belt 14 moves up and down and vibrates, the material will move up and down on the surface of the conveyor belt 14. Since the metal scraps are heavy, during the reciprocating motion of the material, the heavier metal scraps will fall into the reflux trough. The conveying direction of the reflux belt 142 in the reflux trough is opposite to that of the conveying direction of the conveyor belt 14. The reflux belt 142 will convey the metal scraps to a position relative to the conveying direction of the conveyor belt 14, so that the crushed plastic scraps and metal scraps can be collected separately.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
