The cooperation of the fixed tube 17, stirring rod 13, and spiral stirring paddle 19 facilitates the mixing of raw materials and improves the mixing efficiency and effect, thus enhancing the practicality of the device. The auger feeder 8 facilitates the transportation of the mixed raw materials.

[0024] In this embodiment, the stirring motor 15 is fixedly installed at the center of the bottom end of the mixing cylinder 1, corresponding to the top of the bottom plate 5. The cylindrical box 16 is fixedly installed inside the mixing cylinder 1, corresponding to the bottom end of the output shaft of the stirring motor 15. A rubber layer is fixedly provided on the outer wall of the cylindrical box 16. A rotating rod 12 is rotatably installed inside the top of the fixed tube 17 and the cylindrical box 16. The bevel gear set 18 includes two bevel gears, which are respectively fixedly installed at the bottom end of the rotating rod 12 and the outer side of the inner end of the spiral stirring paddle 19. The two bevel gears are mutually... The bevel gear set 18 is located inside the cylindrical box 16, and stirring rods 13 are fixedly installed on both sides of the outer wall of the fixed tube 17. The stirring motor 15 can drive the cylindrical box 16, the fixed tube 17 and the stirring rods 13 to rotate inside the mixing cylinder 1. At the same time, the cylindrical box 16 drives the spiral stirring paddle 19 to rotate inside the mixing cylinder 1 with the output shaft of the stirring motor 15 as the axis. Under the action of the bevel gear set 18 and the rotating rod 12, the spiral stirring paddle 19 can rotate itself, which facilitates the mixing and stirring of the raw materials inside the mixing cylinder 1 and can improve the mixing efficiency of the raw materials.

[0025] In this embodiment, the connecting cylinder 4 is fixedly connected to the top of the mixing cylinder 1, the dual-axis motor 9 is fixedly installed between the top of the mixing cylinder 1 and the discharging cylinder 2, and the turntable 10 is fixedly installed on the top output shaft of the dual-axis motor 9. One end of the turntable 10 has an internal through hole 11, which is located between the placement groove 3 and the connecting cylinder 4. The top of the rotating rod 12 is fixedly connected to the bottom output shaft of the dual-axis motor 9. The dual-axis motor 9 can drive the turntable 10 to rotate inside the discharging cylinder 2. The turntable 10 drives the through hole 11 to move and connect with the corresponding placement groove 3 and the connecting cylinder 4, which facilitates the discharge of raw materials from the corresponding placement groove 3 into the mixing cylinder 1, making it convenient to add raw materials separately, thereby uniformly mixing the raw materials and ensuring the product quality of the plastic sheet.

[0026] In this embodiment, a discharge port is provided on one side of the bottom end of the mixing cylinder 1. The discharge port is located on one side of the spiral agitator 19. An observation window is provided on the side of the discharge port corresponding to the inside of the front wall of the mixing cylinder 1. The auger feeder 8 is located on one side of the discharge port. A connecting pipe is fixedly connected between the auger feeder 8 and the discharge port. An arc-shaped baffle 7 is slidably provided on the inner side of the discharge port corresponding to the inner wall of the mixing cylinder 1. A handle is fixedly provided on the convex wall of the arc-shaped baffle 7. By adjusting the spiral agitator 19 to the position of the discharge port, and driving the spiral agitator 19 to rotate through the dual-shaft motor 9, the rotating rod 12 and the bevel gear set 18, it is convenient to discharge the raw materials to the discharge port, and facilitate the subsequent conveying of the raw materials by the auger feeder 8.

[0027] When using this high-efficiency mixing and conveying device for plastic sheet production, the baffle 7 is moved downwards by the handle and blocked inside the discharge port to facilitate sealing of the discharge port. The raw material conveying equipment conveys the plastic sheet raw material to the corresponding placement tank 3. The dual-shaft motor 9 and its matching circuit drive the turntable 10 to rotate. The turntable 10 drives the through hole 11 to move and align with the corresponding placement tank 3 and connecting cylinder 4, facilitating the discharge of the raw material inside the placement tank 3 into the mixing cylinder 1 through the through hole 11 and connecting cylinder 4. Large particles, small particles, liquids, and additives are placed in the placement tank 3 in sequence. The large particles, small particles, liquids, and additives are then discharged into the mixing cylinder 1 in sequence. During feeding, the stirring motor 15 and its matching circuit drive the cylindrical box 16 to rotate inside the mixing cylinder 1. The cylindrical box 16 drives the spiral stirring paddle 19, the fixed pipe 17, and the stirring rod 13 to mix and stir the materials inside the mixing cylinder 1. The spiral stirring paddle 19 rotates around the output shaft of the stirring motor 15. When the dual-shaft motor 9 stops running, the rotating rod 12 and the top... The bevel gear in the part stops rotating, and the rotation of the spiral agitator 19 drives the bevel gear at one end to rotate. Through the meshing of the two bevel gears, the spiral agitator 19 can rotate on the cylindrical box 16 with its central axis as the center, which facilitates uniform mixing of the raw materials, improves the mixing efficiency and effect of the raw materials, and enhances the practicality of the device. After the mixing is completed, the position of the spiral agitator 19 can be observed through the observation window. At the same time, the stirring motor 15 and its matching circuit drive the cylindrical box 16 and the spiral agitator 19 to rotate and adjust, and adjust the spiral agitator 19 to the position of the discharge port. The dual-shaft motor 9 and its matching circuit drive the rotating rod 12 to rotate. The rotating rod 12 drives the spiral agitator 19 to rotate through the bevel gear set 18, and pushes the raw materials to the position of the discharge port. The baffle 7 is moved upward by the handle. The raw materials enter the interior of the auger feeder 8 through the discharge port and connecting pipe, and are conveyed by the auger feeder 8, which facilitates the subsequent feeding of the raw materials into the extruder for melt extrusion, which facilitates the production and processing of plastic sheets.
