In the figure: 1 extruder head, 11 preformed holes, 12 guide pipes, 13 shunting holes, 14 external threads, 2 outer frames, 21 abutting cavities, 22 heat preservation cavities, 23 reinforcing rods, 3 filter frames, 31 first filter screens, 32 second filter screens and 4 extruders.

Detailed Description

Referring to fig. 1, an extruder with an improved extruder head comprises an extruder head 1, a guide pipe 12 is arranged on the surface of the extruder head 1, a diversion hole 13 is arranged on the surface of the guide pipe 12, the diversion holes 13 are uniformly arranged on the surface of the guide pipe 12, plastic solution is uniformly distributed from the surface of the guide pipe 12 to a circle through the diversion hole 13, one end of the extruder head 1 is connected with an extruder 4, the surface of the extruder head 1 is in threaded connection with an outer frame 2, and an abutting cavity 21 is arranged on the inner side of the outer frame 2.

Referring to fig. 1, the surface of the guide tube 12 is sleeved with the filter frame 3, one end of the filter frame 3 is in contact with the abutting cavity 21, the outer frame 2 rotates inwards along the external thread 14, and the abutting cavity 21 abuts against the filter frame 3 to fix the filter frame 3 between the outer frame 2 and the extruder head 1.

Referring to fig. 1, 3 and 4, a first filter screen 31 and a second filter screen 32 are disposed on the surface of the filter frame 3, the first filter screen 31 is a coarse filter screen, the second filter screen 32 is a fine filter screen, and the plastic solution is filtered by the first filter screen 31 and the second filter screen 32 to reduce the impurities therein.

Referring to fig. 1, a heat preservation chamber 22 is disposed inside the outer frame 2, and the heat loss of the extruder head 1 during operation is reduced and the temperature of the surface of the outer frame 2 is reduced by the heat preservation chamber 22.

Referring to fig. 1, the force applying rods 23 are welded on the surface of the outer frame 2, the number of the force applying rods 23 is two, and the outer frame 2 can be conveniently rotated through the force applying rods 23.
