Detailed Description

The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

As shown in figure 1, the extruding machine comprises a feed hopper 1 and a machine barrel 8 arranged below the feed hopper 1, wherein a stirring device 2 is arranged in the feed hopper 1, and a driving motor 3 for driving the stirring device 2 to rotate is fixedly connected to the outer side wall of the feed hopper 1.

As shown in fig. 1, the stirring device 2 includes a stirring shaft 21 coaxially and fixedly connected to the rotor of the driving motor 3 and a stirring ring 22 coaxially disposed with the stirring shaft 21, a plurality of connecting rods 24 (see fig. 2) facing the center of the stirring ring 22 are fixedly connected to the inner circumference of the stirring ring 22, and one end of the connecting rod 24 far away from the stirring ring 22 is fixed to the stirring shaft 21. A plurality of stirring blocks 23 are arrayed on the outer circumference of the stirring ring 22. The driving motor 3 drives the stirring shaft 21 to rotate, thereby driving the stirring ring 22 to rotate, stirring ring 22 rotates in-process, stirring block 23 stirs the material, and then makes the material difficult for piling up at the discharge gate of feeder hopper 1, makes the material descend more smoothly, has improved the work efficiency of extruding machine.

As shown in FIG. 1, a plurality of stirring rods 211 perpendicular to the axis of the stirring shaft 21 are fixedly connected to the stirring shaft 21. The stirring rod 211 can further break up the material, makes things convenient for the material whereabouts to the barrel more in, improves the work efficiency of extruding machine.

As shown in fig. 1, a rotary joint 41 is fixedly connected to the stirring shaft 21, the rotary joint 41 is located outside the feeding hopper 1, an air inlet pipe 42 is connected to one end of the rotary joint 41, and an air pump 4 is connected to one end of the air inlet pipe 42 away from the stirring shaft 21. The inside of (mixing) shaft 21, the inside of stirring ring 22, the inside of connecting rod 24 and the inside of stirring piece 23 all are hollow, and communicate each other, all are equipped with air nozzle 231 on every stirring ring 22. Equal fixedly connected with filter pulp 232 on every air nozzle 231, filter pulp 232 makes the dust in the material difficult to get into and blocks up air nozzle 231 in air nozzle 231, prolongs air nozzle 231's life. Stirring ring 22 is at the in-process of stirring the material, and air pump 4 will be gaseous carry to each stirring piece 23, then spout from each air nozzle 231 to make (mixing) shaft 21 when stirring the material, blow away the accumulational material, make the material whereabouts more smooth and easy.
