Detailed Description

The technical solution of the present invention is further explained by the accompanying drawings and examples.

The efficient PVC-O pipe extrusion molding device shown in the figure 1-2 comprises a power mechanism, a feed hopper 1, a heating ring 3, a screw rod 2 and a shaping mechanism. The shaping mechanism comprises a guide pipeline 14 and a pipe blank 4, and a circle of gap is uniformly arranged between the guide pipeline 14 and the pipe blank 4. The heating ring 3 processes the materials into a molten state, and then the materials are mixed and extruded by the screw rod 2 and then enter the shaping mechanism for shaping.

In this embodiment, for guaranteeing that the material particle size is even in getting into the feed cylinder, set up the shale shaker below feeder hopper 1.

The outer surface of the pipe blank 4 is provided with an anti-sticking layer, and the anti-sticking layer can be made of polytetrafluoroethylene materials and used for reducing the adhesion rate of a molten material and a shaping mechanism.

The pipe blank 4 is divided into a guide section 10, a shaping section 11 and a shaping section 12. The guide section 10 is a solid bullet-shaped structure, and the shaping section 11 and the shaping section 12 are hollow bin body structures. The guide section 10 is located at the end of the screw 2, and the front side of the shaping section 11 is fixed on the inner wall of the guide pipeline 14 through a supporting block 13. The balance and fixation of the pipe blank 4 are realized through the matching of the guide section 10 and the supporting block 13.

The shaping section 11 is provided with an air blowing layer 5 in a bin, and the shaping section 12 is provided with a condensation layer 7 in a bin. The guide pipeline 14 is provided with a blowing layer 5 and a condensing layer 7 corresponding to the regions of the shaping section 11 and the shaping section 12 respectively. The blowing layer 5 is communicated with an external air pump through a conduit 6, and the condensing layer 7 is communicated with an external circulating pump through a conduit 6. The temperature of the blown gas and the temperature of the condensed water can be adjusted as necessary. The pipe 6 enters the pipe blank 4 part and is arranged between the supporting blocks 13, so that the influence on the later forming of the pipe is reduced as much as possible. The material in the molten state enters the shaping section 11, and the air blowing layer 5 forms an air film on the surfaces of the pipe blank 4 and the guide pipeline 14, so that the molten material is not adhered to the surface of the shaping mechanism, and the shaping speed is accelerated. The shaped pipe is condensed through the condensation layer 7, and then the quick shaping of the pipe is realized.

An annular cooling bin 8 is further fixed at the tail end of the guide pipeline 14, the cooling bin 8 is communicated with an external air pump, and nozzles 9 are uniformly arranged on the inner wall of the cooling bin 8. After being extruded from the guide pipeline 14, the pipe is cooled by the cooling bin 8, so that the setting of the pipe is further accelerated.
