Abstract

The utility model discloses a thermosetting powder extruder, which is achieved on the basis of an existing single threaded rod and a double threaded rod extruder through improving. The utility model is characterized in that three threaded rod assemblies 8 are separately driven by the external gear output shafts of a transfer case B, C and D; the inner wall of a spiral cylinder 11 is provided with three holes which are uniformly distributed in 120 DEG; the three threaded rod assemblies 8 are arranged in the three holes and are uniformly distributed in 120 DEG to form the arrangement of an equilateral triangle. In order to obtain a better pugging, the pugging blocks 10 are triangle-shaped or tooth-shaped. The orders of the pugging blocks 10 can be exchanged arbitrarily back and forth among the threaded rod assemblies to be arranged in various combination angles. The utility model is an ideal thermosetting powder extruder at present.

Description

The powder thermosetting extruder

The powder thermosetting extruder that the utility model relates to belongs to the powder thermosetting process equipment, is a kind of three screw rod powder thermosetting extruders specifically.

Existing powder thermosetting extruder has a kind of series of single screw rod twin-screw (screw rod center line word order), and mixing all is to adopt the oval arrangement of forming various angles, impel material mixing, because existing screw rod word order, draw ratio is bigger, and material solidifies in barrel easily, influence product quality, because screw rod is longer, is again cantilever design, occurs sweeping the boring phenomenon between barrel and the screw rod easily, mixing poor with homo-effect, power consumption is big.

The purpose of this utility model is intended to improve above-mentioned deficiency, and a kind of three screw rod powder thermosetting extruders are provided.

In order to achieve the above object, the utility model is to realize like this, it has a buncher 1, buncher 1 drives one speed reducer 3 by a belt 2, decelerator 3 is connected with transfer case 5 rigidity by coupling band 4, transfer case 5 power shafts drive transfer case external gear output shaft B by transfer case internal tooth A, C, D, transfer case external gear output shaft B, C, D drives three coupling bands 6 respectively, it also has a barrel 11, connects a hopper 7 on the barrel 11, fixes a heating plate 12 on barrel 11 outer circle walls, be characterized in that three coupling bands 6 connect three screw rod assemblies 8 respectively, connect swivel nut 9 successively with flat key 14 on the screw rod assembly 8, mixing 10, little swivel nut 13, barrel 11 inwalls are established three holes, three centerline holes are 120 ° and evenly distribute, and three screw rod assemblies 8 place three holes, are 120 ° of uniform triangular arranged.

In order to make the mixing ground of material better, mixing 10 is triangle or profile of tooth.

During work, by buncher 1 driving torque is driven by belt 2, power is sent on the decelerator 3, decelerator 3 drives transfer case 5 by coupling band 4, transfer case 5 power shafts are sent to power respectively on external gear output shaft B, C, the D by transfer case internal tooth A, drive three screw rod assemblies 8 respectively by three coupling bands 6 and rotate together.Material is entered in the barrel 11 by feed hopper, heating plate 12 begins heating by power supply, three screw rod assemblies 8 in the barrel 11 are rotating with speed, material is pushed ahead by the swivel nut 9 that rotates, and when material was pulled to mixing 10 on triangle, material carried out shear-mixed, material continues to be pushed into, be pulled to mixing of profile of tooth at 10 o'clock, material mixes homogenizing once more, and the material of mixing is released outside the barrels 11 by little swivel nut 13.

The utility model compact conformation, novel, owing to adopted three centerline holes in three screw rod center lines and the barrel to be 120 ° of uniform triangular arranged, shortened the draw ratio of screw rod, make material be difficult for solidifying, owing to adopted mixing of triangle or profile of tooth, improved mixing and homo-effect, self-cleaning ability is strong, has solved to sweep the boring phenomenon, power consumption is low, is present a kind of more satisfactory powder thermosetting extruder.
