[0033] At the top of the inside of the molding box 7, a molding cylinder is fixedly installed. The output end of the molding cylinder is fixedly connected to a molding plate 24; below the molding plate 24, a cooling unit is provided. The cooling unit includes two symmetrically arranged side cooling plates 26. Between the two side cooling plates 26, a lower cooling plate is provided. The lower cooling plate is embedded in the middle of the pushing plate 22. Inside the lower cooling plate and the two side cooling plates 26, a refrigeration pipe 25 is embedded. Refrigerant circulates inside the refrigeration pipe 25. One side of the refrigeration pipe 25 is fixedly connected to an external refrigeration device through a connecting pipe; by arranging the cooling unit, during the molding operation, the molding groove 23 is cooled to accelerate the cooling and shaping of the raw material; at the bottom of one side of the molding box 7, a discharge port is provided. One side of the discharge port is fixedly connected to a supporting bracket. One end of the pushing plate extends into the supporting bracket;

[0034] The other end of the pushing plate 22 is provided with a air supply unit. The air supply unit includes an air supply plate 20 which is embedded in the inner wall of the molding box 7. A plurality of air inlet pipes 21 are fixedly connected to the middle of the air supply plate 20. All the plurality of air inlet pipes 21 are communicated with the output end of the external air supply equipment. By providing the air supply unit, when the strip-shaped raw material surges into the die groove, it is blown to cool down, which is convenient for the subsequent shaping operation during molding.

[0035] A temporary storage box 2 is arranged above the mixing box 1. The top of the temporary storage box 2 is rotatably connected with a top cover 32. A feeding port is arranged on one side of the temporary storage box 2. The bottom of the temporary storage box 2 is provided with a through port, and the bottom of the through port is correspondingly arranged with the top of the feeding port. Both sides of the inner wall of the temporary storage box 2 are fixedly connected with inclined plates 29. Feeding cylinders are fixedly installed inside both inclined plates 29. The output end of the feeding cylinder is fixedly connected with a closing plate 28. When the two feeding cylinders extend to the limit position, one ends of the two closing plates 28 are in close contact to block and close the through port. By providing the temporary storage box 2, the raw materials to be mixed are temporarily stored, so that when the mixing box 1 is performing the mixing operation, the next batch of raw materials can be pre-proportionally stored, thereby improving the production efficiency.

[0036] A feeding hopper 3 is fixedly connected to one side of the feeding port. A plurality of powder pressing rollers 27 arranged in a staggered manner are rotatably connected to the inner wall of the feeding hopper 3. By providing the powder pressing rollers 27, the large particles in the fed raw materials are rolled and crushed, improving the material uniformity to facilitate the subsequent mixing and extrusion operations.

[0037] When the present invention is in use, the raw materials for producing the PVC wood-plastic board are fed into the feeding hopper 3 from the feeding port. A plurality of dividing rollers rotate to roll and crush the large-particle raw materials and push the raw materials into the temporary storage box 2. After all the raw material feeding operations are completed, the two feeding cylinders are started to drive the two closing plates 28 to retract, so that the through port is opened, and the raw materials pass through the through port and enter the mixing box 1 from the feeding port;

[0038] The mixing motor 8 is started to drive the mixing rotating plate to rotate, and then drive a plurality of stirring rods 9 and the stirring arc plate 10 to rotate to turn and stir the raw materials. At the same time, the rotation of the mixing rotating plate drives the stirring shaft 11 to rotate, driving the rotation of the two spiral stirring plates 12 to push the raw materials towards the middle of the mixing box 1, realizing the full and uniform stirring and mixing of the raw materials inside the mixing box 1;

[0039] After mixing is completed, the discharging cylinder 14 starts to drive the discharging push plate and the docking plate to retract, causing the discharging plate 13 to flip open. The raw materials are discharged from the discharging port, fall along the discharging plate 13 into the guiding pipe 4, are received by the guiding conveyor belt 15, and are sent into the extruder 5 through the rotation of the guiding conveyor belt 15. After being extruded by the extruder 5, they are sent out from the output end, pass through the gap between the two calendering rollers 30, and are rolled into a strip shape by the rotation of the two calendering rollers 30. Then, through the rotation of several guiding rollers 31, the strip-shaped raw materials are sent into the forming box 7 from the guiding port;

[0040] The strip-shaped raw materials entering the forming box 7 fall along the guiding plate, bypass the guiding roller 19 and fall into contact with one side of the pushing guide roller 18. Then, the pushing cylinder 17 starts to push the strip-shaped raw materials to move, causing their ends to fall downward into the molding groove 23. Then, the pushing cylinder 17 drives the pushing guide roller 18 to move back and forth, cooperating with the conveying and falling of the raw materials themselves, so that the strip-shaped raw materials falling into the molding groove 23 are bent and stacked layer by layer. When the length of the strip-shaped raw materials meets the requirements of molding, the cutting knife 33 starts to work and cuts off the strip-shaped raw materials;

[0041] During the process of feeding the raw materials into the molding groove 23, air flow is sent into several air supply pipes by an external air supply device to cool the strip-shaped raw materials. When the raw materials are completely fed into the mold groove, the pushing guide rail drives the molding groove 23 to move under the mold pressing plate 24, and the mold pressing cylinder drives the mold pressing plate 24 to press down, pressing the raw materials in the molding groove 23 into shape. At the same time, an external refrigeration device circulates refrigerant to the refrigeration pipe 25 to cool the side cooling plate 26 and the lower cooling plate, thereby realizing the cooling of the molding groove 23 and the raw materials and accelerating the shaping speed of the raw materials. Then, the mold pressing cylinder drives the mold pressing plate 24 to move up and reset, and the pushing guide rail sends the molding groove 23 out from the discharging port.
