Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1-6, a novel screw extruder comprises a barrel 1, a feed inlet 2 is formed in one side of the top of the barrel 1, a screw 12 is arranged in the barrel 1, a connecting block 13 and a fixed pipe 11 are respectively arranged at two ends of the screw 12 in the barrel 1, one end of the connecting block 13 is connected with a shaft rod 3, one end of the shaft rod 3, which is opposite to the connecting block 13, extends to the outside of the barrel 1, a clamping mechanism for clamping the screw 12 is arranged between the connecting block 13 and the fixed pipe 11, one end of the barrel 1, which is opposite to the shaft rod 3, is connected with a flow guide cover 6 through threaded screwing, and a discharge mechanism is arranged in the;

the clamping mechanism comprises a limiting disc 15 and two inserting blocks 14, the two inserting blocks 14 are respectively fixed on two sides of the screw 12, the limiting disc 15 is rotatably connected with the inside of the fixed pipe 11 through a rotating shaft, inserting holes 16 matched with the inserting blocks 14 are formed in one side, opposite to the limiting disc 15 and the connecting block 13, of the limiting disc 15, a plurality of through holes 17 are formed in the position, located outside the inserting holes 16, of the inside of the limiting disc 15 in an annular array mode, and the conveying process of materials can not be influenced when the screw 12 rotates by means of the through holes 17;

the insert 14 is of an integral structure with the screw 12, and the cross-sectional shapes of the insert 14 and the insertion hole 16 are square, so that the screw 12 can rotate synchronously with the connecting block 13.

Through the technical scheme:

when the device is used, the screw 12, the connecting block 13 and the limiting disc 15 can form a whole through the jack 16, and then the screw 12 can rotate in the cylinder 1 when the connecting block 13 is driven to rotate through the shaft rod 3;

after the material is put into the cylinder body 1 through the feed inlet 2, the material can be conveyed towards the direction of the flow guide cover 6 in the rotating process of the screw 12;

after the fixed pipe 11 is separated from the cylinder 1, the screw 12 can be directly taken out of the cylinder 1, and the screw 12 is convenient to clean or replace.

Referring to fig. 1 and 6, the discharging mechanism comprises a limiting frame 5, the limiting frame 5 is located inside the air guide sleeve 6, a silica gel ring 10 is sleeved on the outer wall of the limiting frame 5 and inside the air guide sleeve 6, one end of the limiting frame 5 is connected with a discharging pipe 8, one end of the discharging pipe 8, opposite to the limiting frame 5, extends to the inside of the air guide sleeve 6, and a spring 9 is sleeved outside the discharging pipe 8 and between the limiting frame 5 and the air guide sleeve 6;
