[0032] In the embodiment of the utility model, in order to be able to make the different plastic particles inside discharge hopper 2 more evenly mixed, specifically, the mixing device includes a partition plate 21, the partition plate 21 is fixedly connected to the inner wall of the discharge hopper 2, the partition plate 21 is provided with a discharge port 211, the discharge port 211 is provided with two groups, the two groups of discharge ports 211 are symmetrically distributed on the two sides of the partition plate 21, the discharge port 211 below is provided with an inclined plate 20, the inclined plate 20 is fixedly connected with the inner wall of the discharge hopper 2, the inclined plate 20 is provided with two groups, the two groups of inclined plates 20 are symmetrically distributed on the two sides of the inner wall of the discharge hopper 2, the outer wall of the partition plate 21 is fixedly provided with a sliding seat 212, the sliding seat 212 is slidably connected with a sliding block 213, the sliding block 213 is provided with a through slot 214, the sliding block 213 is elastically connected with the sliding seat 212 through a spring, the rotating shaft 24 penetrates the discharge hopper 2 and the partition plate 21 and is rotatably connected with the discharge hopper 2 and the partition plate 21, the upper end of the rotating shaft 24 is slidably connected with an elastic clamping block two 242, the lower end of the rotating shaft 24 is slidably connected with an elastic clamping block one 241, the extrusion block 25 is penetrated by the rotating shaft 24 and is rotatably connected with the rotating shaft 24, the extrusion block 25 is provided with a clamping groove one 251, the rotating rod 26 penetrates the rotating shaft 24 and is rotatably connected with the rotating shaft 24, the rotating rod 26 is provided with a clamping groove two 260, the outer wall of the rotating rod 26 is fixedly connected with a stirring rod 261;

[0033] Further, the rotating rod 26 is penetrated by the moving rod 262 and is sleeved with the moving rod 262, one end of the moving rod 262 is fixedly connected with a piston 263, the other end of the moving rod 262 is fixedly connected with the hydraulic cylinder output;

[0034] Further, the rotating shaft 24 is drivingly connected with a transmission belt 23, the transmission belt 23 is drivingly connected with a transmission wheel, and the transmission wheel is fixedly connected with the output end of the motor 22;

[0035] In the utility model, when using, first, two different raw materials are placed on the two sides of the partition plate 21, then the motor 22 is started, it is need to say that when the motor 22 is driven by external power supply, when the motor 22 is started, at this time, the transmission of the transmission belt 23 makes the rotating shaft 24 rotate counterclockwise, when the rotating shaft 24 rotates counterclockwise, as shown in Figure 7 At this time, the right angle edge of the elastic clamping block one 241 will exert force on the clamping groove one 251, so that the extrusion block 25 rotates synchronously with the rotating shaft 24, at the same time, as shown in Figure 8As shown, during this process, the inclined surface of the second elastic block 242 will be squeezed by the second slot 260, causing the second elastic block 242 to completely disengage from the second slot 260, at which point the rotating rod 26 remains stationary.

[0036] like Figure 4 As shown, when the extrusion block 25 rotates, it will extrude the sliding block 213, causing the sliding block 213 to move. When the sliding block 213 moves, the through groove 214 will overlap with the discharge port 211. At this time, the raw material in the partition plate 21 will quantitatively pass through the discharge port 211 into the discharge bucket 2. At the same time, during the discharge process, the raw material will impact the inclined plate 20. Under the action of the impact force, the two materials can be mixed and evenly sprinkled into the discharge bucket 2. Through the design of the inclined plate 20, the discharge port 211, the extrusion block 25 and the sliding block 213, the device can quantitatively and evenly sprinkle the two raw materials into the discharge bucket 2, thereby improving the mixing effect of the raw materials.

[0037] When a certain amount of raw material is stored inside the feeding hopper 2, the drive motor 22 causes the rotating shaft 24 to rotate clockwise. When the rotating shaft 24 rotates clockwise, the right-angled side of the elastic locking block 242 applies force to the locking groove 260, causing the rotating rod 26 to rotate. Simultaneously, the inclined surface of the elastic locking block 241 is squeezed by the locking groove 251, causing the elastic locking block 241 to disengage from the locking groove 251. At this time, the squeezing block 25 remains stationary. When the rotating rod 26 rotates, the squeezing block 25... The fixedly connected stirring rod 261 will mix the raw materials inside the feeding barrel 2 again, thereby improving the mixing efficiency of the raw materials. When the mixing is completed, the motor 22 is turned off and the hydraulic cylinder is started. When the hydraulic cylinder is started, the moving rod 262 fixedly connected to the output end of the hydraulic cylinder will drive the piston 263 to move upward, thereby opening the discharge port of the feeding barrel 2. With this design, the raw materials will enter the conveying cylinder 1 through the discharge port, and then be conveyed to the heating device 3 by the auger 5 for heating treatment.
