The rotation of the rotating tube and the stirring blades can stir and mix the PETG material and the auxiliary materials. The rotation of the rotating rod and the conveying auger can transport the PETG material and the auxiliary materials at the bottom of the mixing tank cavity upward, so that the lower layer of materials can come into contact with the upper layer of materials, realize the exchange of the upper and lower layer materials, further increase the uniformity of the material mixing, and ensure that the upper and lower layer materials can be fully mixed. By connecting the anti-blocking auger at the bottom of the conveying auger, the conveying direction of the anti-blocking auger is opposite to that of the conveying auger, and the conveying auger is rotated to drive the anti-blocking auger to rotate. The anti-blocking auger can transport the material downward, thereby avoiding the situation where the material blocks the discharge pipe during discharge.
[0026] Furthermore, a sealing cover 13 is threadedly connected to the surface of the discharge pipe 8, and two support rods 14 fixedly connected to the sealing cover 13 are provided inside the discharge pipe 8. Through the setting of the sealing cover 13 and the support rods 14, the sealing cover 13 is used to limit the position of the baffle plate 15, and the support rods 14 are used to support the baffle plate 15.
[0027] Furthermore, the inside of the discharge pipe 8 is also provided with a baffle plate 15 fixedly connected to the support rod 14, and the inside of the baffle plate 15 is provided with a through groove 16 which is sleeved with the baffle block 10, and the surface of the baffle plate 15 is slidably connected to the inner wall of the discharge pipe 8. The baffle plate 15 is provided to block the PETG material and auxiliary materials inside the mixing tank 1.
[0028] Furthermore, a protective shell 17 is installed on the top of the mixing tank 1 by screws, and one side of the inner cavity of the protective shell 17 is installed with the motor 7 through a bracket. The setting of the protective shell 17 is used to cooperate with the bracket to support the motor 7 and at the same time protect its internal structure.
[0029] Furthermore, the diameter of the through slot 16 is larger than that of the anti-blocking auger 9 and the material blocking block 10 , which facilitates the anti-blocking auger 9 and the material blocking block 10 to pass through the through slot 16 inside the material blocking plate 15 .
[0030] Furthermore, a feeding hopper 18 is connected to the top of the mixing tank 1, and two connecting rods 19 are fixedly sleeved on the surface of the sealing cover 13. The setting of the feeding hopper 18 makes it convenient for personnel to add auxiliary materials and PETG materials into the interior of the mixing tank 1; the setting of the connecting rods 19 makes it convenient for personnel to rotate the sealing cover 13, thereby facilitating the installation and removal of the sealing cover 13.
[0031] Brief description of the use process: When in use, PETG material and auxiliary materials are put into the mixing tank 1 through the feeding hopper 18.
[0032] The motor 7 is started, and its output end rotates clockwise and drives the gear 2 12 to rotate. The gear 2 12 drives the two gears 6 meshing with it to rotate counterclockwise. The two gears 6 respectively drive the rotating tube 2 and the rotating rod 3 to rotate counterclockwise. The rotation of the rotating tube 2 drives the stirring blades 11 on its surface to stir the material. The rotation of the rotating rod 3 drives the conveying auger 4 to rotate. The conveying auger 4 rotates to convey the material in the lower layer inside the mixing tank 1 upward and discharge it through the discharge port 5, so that the lower layer material and the upper layer material can contact each other, and the lower layer material and the upper layer material can be alternated under continuous conveying, so that the material inside the mixing tank 1 can avoid the situation that the lower layer material is stirred and mixed, and the upper layer material cannot be stirred. Under the alternating action, the upper and lower layer materials inside the device can be evenly mixed.
[0033] After the mixing is completed, the motor 7 is turned off, and the connecting rod 19 is rotated to drive the sealing cover 13 to rotate, so that the sealing cover 13 and the discharge pipe 8 are separated, and then the sealing cover 13 is pulled downward, and the sealing cover 13 drives the support rod 14 and the material blocking plate 15 to separate from the discharge pipe 8, and the material is discharged downward through the discharge pipe 8. If the material is blocked during the material discharge process, it is only necessary to turn on the motor 7, and the motor 7 drives the rotating rod 3, the conveying auger 4, and the anti-blocking auger 9 to rotate. Since the anti-blocking auger 9 and the conveying auger 4 have opposite conveying directions, the conveying auger 4 conveys upward, and the anti-blocking auger 9 conveys downward. The anti-blocking auger 9 can push the material downward, thereby avoiding the occurrence of material blockage.
