[0028] See also Figure 1 , the utility model provides the embodiment:

[0029] A waste discharge device for an extruder screw cleaning machine comprises a waste collection bin installed on the bottom of the extruder screw cleaning machine, a waste trough 1 is provided inside the waste collection bin, the residue and cleaning liquid from the extruder screw cleaning are collected and processed through the waste trough 1, a spiral chip removal device 2 is fixedly installed on the waste trough 1, and the spiral chip removal device 2 is located on the bottom surface of the waste trough 1;

[0030] Specifically, the outer edges of the waste trough 1 are inclined on both sides, and the bottom surface of the waste trough 1 is a collecting trough 10 with a semicircular structure. The outer edge of the waste trough 1 with an inclined structure can allow the residue to slide on the surface, and the semicircular collection groove 10 on the bottom surface of the waste trough 1 can gather and collect the residue that has fallen.

[0031] The spiral chip removal device 2 includes a bearing seat 3, a shaft rod 8 and a spiral blade 9. The side walls of the waste collection bin are fixed to the bearing seat 3 by screws, the inner ring of the bearing seat 3 is fixed to the two ends of the shaft rod 8, and the spiral blade 9 is welded to the side wall of the shaft rod 8. The side wall of the spiral blade 9 is slidably connected to the collection trough 10. The shaft rod 8 rotates on the two bearing seats 3, so that the spiral blade 9 on the side wall can slide on the collection trough 10, and push the residue collected in the collection trough 10 while sliding, so that the waste trough 1 is processed for chip removal.

[0032] The end of the shaft rod 8 is connected to the speed regulating motor 5 through a transmission mechanism, and the transmission mechanism includes a driving sprocket 15, a chain 7 and a driven sprocket 4. The output shaft of the speed regulating motor 5 is connected to the internal key of the driving sprocket 15, the end of the shaft rod 8 is connected to the internal key of the driven sprocket 4, and the side wall of the driven sprocket 4 is connected to the driving sprocket 15 through the chain 7.

[0033] During specific use, the speed regulating motor 5 drives the driving sprocket 15 to rotate, and the driven sprocket 4 can rotate under the transmission of the chain 7, so that the shaft rod 8 can rotate on the waste trough 1, thereby providing rotational power for the shaft rod 8.

[0034] A chip discharge port 6 is provided at one end of the waste trough 1. As the spiral blade 9 rotates, the residue collected in the collecting trough 10 is pushed and displaced, and the residue is pushed to the chip discharge port 6, so that the residue is discharged into the waste collection bin of the extruder screw cleaning machine through the chip discharge port 6.

[0035] Flushing mechanisms for flushing the surface of the waste trough 1 are respectively installed on both sides of the outer edge of the waste trough 1, and the flushing mechanism includes a water pipe 12, a nozzle 13 and a water inlet pipe 14.

One end of the water pipe 12 is a closed surface, and the other end of the water pipe 12 is docked and installed with a water inlet pipe 14.

[0036] In order to better prevent lighter residues from staying on the surface of the waste tank 1, a water inlet pipe 14 cooperates with a high-pressure pump to provide high-pressure water to the water pipe 12. The high-pressure water is sprayed out through multiple nozzles 13 on the side wall of the water pipe 12 to flush the residues staying on the surface of the waste tank 1, so that the residues can enter the collection tank 10, thereby ensuring that the residues in the waste tank 1 are not easy to stay and do not cause accumulation.

[0037] As a preferred solution of the present application, a plurality of nozzles 13 are equidistantly arranged on the side wall of the water pipe 12, and the nozzles of the nozzles 13 are flat. The nozzles of the nozzles 13 are directed toward the surface of the waste tank 1. Through the flat nozzles, water is sprayed out through a larger range of water curtain through the flat nozzles, thereby ensuring that the surface of the waste tank 1 can be flushed clean.
