Through the spiral strip of welding at body 1 inner wall, the unloading of material storehouse of can being convenient for, the material produces decurrent pressure under the effect of spiral, ensures the certain material pressure of lower part material. Through inserting the screw body 2 upper end into the material bin 7, and the screw body 2 stretches into the material bin 7 a certain distance, play the effect of helping to flow to the material, the body lower part connects roll squeezer feed inlet 9, because the material is full state from material bin 7 to body 1 to roll squeezer roll surface again when the roll squeezer is running, the screw body 2 can be given a decurrent pressure of material of bottom voluntarily when body 1 rotates to replace material gravity to exert the charging pressure. The pipe body leaves certain space in the middle part of the spiral body 2, thereby ensuring that larger materials can pass smoothly.

The driving device of the embodiment of the invention comprises a first sprocket 12, a second sprocket 13, a distance limiting coupler 14 and a gear motor 15, wherein the first sprocket 12 is sleeved on the outer wall of the pipe body 1 and fixedly connected with the middle flange 2 through bolts.

After the pressure has been applied, the screw 2 is subjected to a vertically upward reaction force which is applied by the axial bearing and transmitted via the screw to the roll press feed opening.

When faults occur, such as blocking of a roller press, the reaction force generated by the rotation of the spiral body 2 on the inner wall of the pipe body 1 is rapidly increased, so that the stress of the second sprocket wheel 13 in the driving device is increased, after the stress of the driving device reaches the set moment of the distance limiting coupler 14, the gear motor 15 is separated from the second sprocket wheel 13, the pipe body 1 stops rotating, no greater pressure is generated, after a part of materials at the bottom of the pipe body is discharged, the stress of the second sprocket wheel 13 is reduced, the distance limiting coupler 14 is restarted, the gear motor 15 drives the second sprocket wheel 13 to rotate again, and the pipe body 1 starts working rotation again.
