[0023] Specifically, a threaded hole 9 is provided at the bottom of the stirring shaft 5, and a mounting rod 10 is fixedly provided at the end of the core shaft 7 for being inserted into the threaded hole 9 and threadedly connected to the threaded hole 9. The core shaft 7 can be conveniently disassembled through the cooperation of the mounting rod 10 and the threaded hole 9, thereby facilitating the replacement of damaged spiral blades 8.

[0024] Specifically, fixed rods 11 are symmetrically fixed on both sides of the stirring shaft 5 at the bottom of the fixed frame 3, and multiple outer stirring rods 12 are fixed on the fixed rods 11. The outer stirring rods 12 are staggered with the inner stirring rod 6. When the inner stirring rod 6 rotates, the stationary outer stirring rods 12 move in the opposite direction relative to the rotating inner stirring rod 6. When the inner stirring rod 6 stirs the raw materials, part of the raw materials are intercepted by the outer stirring rods 12 and move relative to the stirred raw materials, thereby increasing the diversity of raw material movement during stirring and improving the stirring and mixing uniformity effect.

[0025] Specifically, the mounting ring 14 is provided with a mounting groove 15 for inserting the plug post 13, the plug post 13 is provided with a through groove 16, the inner wall of the mounting groove 15 is provided with a block groove 17, and a block 18 for inserting into the through groove 16 to limit the plug post 13 is slidably provided in the block groove 17, a threaded groove 19 is provided at one end of the block 18 away from the mounting groove 15, a screw 20 is threadedly connected to the threaded groove 19, a rotating groove 21 for the screw 20 to pass through and rotatably connected to the screw 20 is provided at the bottom of the block groove 17, a knob 22 is fixedly connected to the end of the screw 20 located outside the rotating groove 21, and the screw 20 is rotated by rotating the knob 22, and the screw 20 is driven to rotate by rotating the knob 22, and the threaded connection between the screw 20 and the threaded groove 19 drives the block 18 to move, so that the block 18 can be moved into the through groove 16 to limit the plug post 13.

[0026] Specifically, a retaining plate 23 is fixedly sleeved on the outer wall of the plug post 13. When installing the fixing frame 3, the plug post 13 is aligned with the mounting groove 15 and inserted until the retaining plate 23 abuts against the mounting ring 14. At this time, the through groove 16 is directly opposite to the block groove 17. The knob 22 is turned to insert the block 18 into the through groove 16 to limit the plug post 13 and complete the fixation.

[0027] Specifically, the inner wall of the block groove 17 is symmetrically provided with a limit groove 24, and a limit block 25 fixedly connected to the side wall of the block 18 is slidably provided in the limit groove 24. The limit of the limit groove 24 and the limit block 25 can prevent the block 18 from sliding out of the block groove 17 too much and causing the plug column 13 to fail to be properly clamped.

[0028] A specific application example of this embodiment is:

[0029] When the device is in use, the motor 4 is started, the motor 4 drives the stirring shaft 5 to rotate, thereby driving the inner stirring rod 6 to rotate, the stirring shaft 5 drives the core shaft 7 to rotate, and the spiral blade 8 rotates. After the raw material is poured from the feed hopper 2, the raw material is stirred and mixed under the action of the inner stirring rod 6 and the outer stirring rod 12, thereby improving the balance of the plastic. The rotating spiral blade 8 pushes the raw material into the extruder, which can avoid the blockage of the raw material and ensure the feeding speed, thereby ensuring the production efficiency of the plastic extruder. When the spiral blade 8 needs to be replaced , rotating the knob 22 drives the screw rod 20 to rotate, and the threaded connection between the screw rod 20 and the threaded groove 19 drives the block 18 to move so that the block 18 is moved out of the through groove 16, so that the fixing frame 3 can be disassembled, and the core shaft 7 is screwed out for replacement. When installing the fixing frame 3, the plug column 13 is aligned with the installation groove 15 and inserted until the abutment plate 23 abuts against the installation ring 14. At this time, the through groove 16 and the block groove 17 are opposite. The knob 22 is turned to insert the block 18 into the through groove 16 to limit the plug column 13, thereby completing the fixation of the fixing frame 3.
