[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figure 1-Figure 5As shown, an extruder for producing flame-retardant threading pipes includes a discharge barrel 101, a mixing barrel 102 is provided above the discharge barrel 101, the mixing barrel 102 is located at the top of one side of the discharge barrel 101, a plurality of support frames 103 are fixedly connected to the bottom of the discharge barrel 101, a support frame 104 is connected to the top of the support frame 103 on one side by bolts, the top of the support frame 104 is connected to the mixing barrel 102 by bolts, a discharge pipe is provided at the bottom of the mixing barrel 102, the discharge pipe is fixedly connected to the discharge barrel 101, and the mixing barrel 102 rotates inside. The movable rod 202 is connected, and the movable rod 202 is coaxial with the mixing barrel 102. The movable rod 202 is evenly distributed with multiple fixed rods 301 along the circumference. The fixed rods 301 are radially symmetrical along the movable rod 202. The end of the fixed rod 301 away from the axial direction of the movable rod 202 is connected to a connecting block 302 by a screw. The connecting block 302 is inclined and has a certain angle with the movable rod 202. A scraper 303 is hinged on the top of one side of the connecting block 302. The scraper 303 has a certain elasticity. Initially, the scraper 303 is in a vertical state. 302, the scraper 303 is fixedly connected to a spring 304 on one side of the connecting block 302, and the spring 304 is fixedly connected to the connecting block 302. A plurality of protrusions 305 are connected to the inner wall of the mixing barrel 102 by screws. The plurality of protrusions 305 are arranged equidistantly along the circumference of the inner wall of the mixing barrel 102. As the material in the mixing barrel 102 decreases, residual material will adhere to the inner wall of the mixing barrel 102. When the movable rod 202 rotates, it drives the fixed rod 301 to rotate, and the fixed rod 301 drives the connecting block 302 to rotate, thereby causing the scraper 303 to rotate. The plate 303 scrapes the residual material on the inner wall of the mixing barrel 102, and then the scraper 303 squeezes the protrusion 305. The scraper 303 rotates around the hinge axis of the connecting block 302 to a certain extent, causing the spring 304 to compress and deform. The scraper 303 has a certain elasticity. After the deformation and separation from the protrusion 305, the spring 304 recovers the deformation and pushes the scraper 303 to rotate around the hinge axis of the connecting block 302, and slaps the inner wall of the mixing barrel 102 to throw off the material accumulated on the scraper 303, avoiding waste caused by excessive residual material.

[0025] The top of the mixing barrel 102 is connected to a mixing motor 201 by bolts, and the output shaft of the mixing motor 201 is connected to the top of the movable rod 202 by a coupling. The movable rod 202 is provided with a flipping plate 203, which is fixed in a spiral shape along the axial direction of the movable rod 202 and is located below the fixed rod 301.

[0026] The bottom of the movable rod 202 is connected to the auger 4 through a coupling. The auger 4 is located in the discharge pipe. The spiral direction of the auger 4 is opposite to that of the flipping plate 203. The mixing motor 201 drives the movable rod 202 to rotate. The movable rod 202 drives the flipping plate 203 to rotate to stir the material in the mixing barrel 102. At the same time, the movable rod 202 drives the auger 4 to rotate. The spiral direction of the auger 4 is opposite to that of the flipping plate 203, which is convenient for continuous stirring while discharging. The auger 4 transports the material to the discharge barrel 101.

[0027] A discharging motor 501 is connected to the discharging barrel 101 on one side close to the mixing barrel 102 via bolts. A screw rod 502 is rotatably connected inside the discharging barrel 101 . The output shaft of the discharging motor 501 is connected to the screw rod 502 via a coupling.

[0028] A feeding hopper 6 is welded to the top of the mixing barrel 102 , and the feeding hopper 6 is located on one side of the mixing motor 201 .

[0029] The side of the discharge barrel 101 away from the discharge motor 501 is connected to the extrusion nozzle 7 through bolts. The discharge motor 501 drives the screw rod 502 to rotate, and transports the material to the extrusion nozzle 7. Then the material is discharged through the extrusion nozzle 7.

[0030] Working principle: When in use, the material is poured into the mixing barrel 102 through the feed hopper 6, and then the mixing motor 201 drives the movable rod 202 to rotate, and the movable rod 202 drives the flip plate 203 to rotate to stir the material in the mixing barrel 102. At the same time, the movable rod 202 drives the auger 4 to rotate. The spiral direction of the auger 4 is opposite to that of the flip plate 203, which is convenient for continuous stirring while unloading. The auger 4 transports the material to the discharge barrel 101, and the discharge motor 501 drives the screw rod 502 to rotate to transport the material to the extrusion nozzle 7. Then the material is discharged through the extrusion nozzle 7. As the material in the mixing barrel 102 decreases, there will be residual material attached to the mixing barrel. 102, the movable rod 202 rotates and drives the fixed rod 301 to rotate, and the fixed rod 301 drives the connecting block 302 to rotate, so that the scraper 303 scrapes the residual material on the inner wall of the mixing barrel 102, and then squeezes the protrusion 305. The scraper 303 rotates around the hinge axis of the connecting block 302 to a certain extent, so that the spring 304 is compressed and deformed. The scraper 303 has a certain elasticity. After the deformation and separation from the protrusion 305, the spring 304 recovers the deformation and pushes the scraper 303 to rotate around the hinge axis of the connecting block 302, and slaps the inner wall of the mixing barrel 102 to throw off the material accumulated on the scraper 303, so as to avoid waste caused by excessive residual material.
