[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a material pressing device for a pelletizer. Figure 1-3 A material pressing device of a pelletizer includes a shell 1, a top cover 4 is arranged above the shell 1, a motor 7 is installed on the upper end of the top cover 4, and the model of the motor 7 can be selected as YE2-6344-37KW. The lower end of the top cover 4 is symmetrically rotatably connected to two reciprocating screws 8, and the two reciprocating screws 8 are commonly threadedly connected with an annular hollow bar 12, and a brush layer 13 is arranged around the outer side of the annular hollow bar 12. A cleaning mechanism for the shell 1 is arranged below the top cover 4.

[0021] Reference Figure 1-3 The cleaning mechanism includes a transmission chamber 10 opened in the top cover 4, the upper ends of the two reciprocating screws 8 extend into the transmission chamber 10 and are fixedly connected with a synchronous transmission wheel, and the two synchronous transmission wheels are connected through a synchronous transmission belt 9. The end of the output shaft of the motor 7 extends into the transmission chamber 10 and is fixedly connected to the upper end of the reciprocating screw 8 on the right side. A plurality of fine holes 14 are arranged around the outer side of the annular hollow bar 12, and the plurality of fine holes 14 are connected with the interior of the annular hollow bar 12, and the plurality of fine holes 14 penetrate the brush layer 13. A connecting pipe 5 is arranged at the upper end of the top cover 4, and the lower end of the connecting pipe 5 extends to the lower end of the top cover 4, and is connected with the interior of the annular hollow bar 12 through a hose 11.

[0022] After the motor 7 is started, the reciprocating screw 8 on the right side rotates. When the reciprocating screw 8 on the right side rotates, the reciprocating screw 8 on the left side will rotate through the transmission of the synchronous transmission belt 9, that is, the two reciprocating screws 8 rotate synchronously, so that the annular hollow bar 12 reciprocates up and down, thereby driving the brush layer 13 to continuously wipe the inner wall of the shell 1 for wiping and cleaning. In this process, the water pump will suck water into the annular hollow bar 12 through the hose 11, and then discharge the water through a plurality of fine holes 14, which cooperates with the brush layer 13 to further improve the cleaning efficiency.

When the reciprocating screw 8 on the right side rotates, the reciprocating screw 8 on the left side rotates through the transmission of the synchronous transmission belt 9, that is, the two reciprocating screws 8 rotate synchronously, so that the annular hollow bar 12 reciprocates up and down, thereby driving the brush layer 13 to continuously wipe the inner wall of the shell 1 for wiping and cleaning. In this process, the water pump will suck water into the annular hollow bar 12 through the hose 11, and then discharge the water through a plurality of fine holes 14, which cooperates with the brush layer 13 to further improve the cleaning efficiency;

[0026] The top cover 4 can be removed later, so that the top cover 4, the annular hollow bar 12 and the brush layer 13 are separated from the shell 1. The split setting is adopted to facilitate subsequent cleaning.
