Description

A screw used for PVC powder direct extrusion wire integrated machine

technical field

The utility model relates to electronic information technology, in particular to a screw used for an integrated machine for directly extruding PVC powder into electric wires.

Background technique

In the prior art, the production of wire and cable is to first make rubber particles and then use the rubber particles to extrude the wires. The extrusion screw is generally used to extrude the rubber-like materials. There is a large waste of electricity, auxiliary materials, manpower, and space.

Therefore, there are defects in the prior art and need to be improved.

Utility model content

The technical problem to be solved by the utility model is to provide a screw rod for PVC powder direct extrusion wire integrated machine which can extrude and knead PVC powder into linear PVC plastic, has simple structure and low production cost.

The technical scheme of the utility model is as follows: a screw used for the PVC powder direct extruding electric wire integrated machine, including a material inlet, and a preheating section, an extruding section, a shunting section, a melting section and a mixing section respectively arranged sequentially.

Applied to the above technical scheme, in the screw described above, the splitter section is respectively provided with a splitter groove, a splitter main screw flight, a splitter main and auxiliary screw flight, and an equidistant gradually changing groove; the melting section is respectively provided with a liquid phase tank and a liquid phase flight , a melting tank and a variable melting distance tank; the mixing section is respectively provided with a solid phase tank, a solid phase screw flight, a mixing screw flight and a mixing tank in sequence.

Applied to each of the above technical solutions, in the screw, from the preheating section to the kneading section, it is set in the shape of a cone that gradually becomes larger.

By adopting the above-mentioned scheme, the utility model sets up the preheating section, the extruding section, the splitting section, the melting section and the mixing section respectively, so that after the PVC powder is mixed and stirred, the preheating, extrusion, and mixing can be completed through the screw. Dividing, melting and kneading process, simple structure, low production cost, good quality extrusion kneading products.

Description of drawings

Fig. 1 is the structural representation of the utility model.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.

This embodiment provides a screw used in an integrated machine for directly extruding PVC powder into wires. The screw in this embodiment is installed inside the integrated machine for directly extruding PVC powder into wires, and can directly extrude and knead PVC powder into linear PVC. The plastic is directly extruded through the PVC powder, and the electric core is added to the fine-tuning head of the all-in-one machine to form the wire to form a wire. There is no need to make a granular and then extrude into a linear PVC plastic, which saves production costs.

As shown in Figure 1, the screw includes a material inlet 2, and a preheating section 3, an extruding section 4, a splitting section, a melting section and a mixing section are arranged sequentially from right to left.

Among them, the diversion section is respectively provided with a diversion tank 5, a main diversion flight 6, a main and auxiliary flight flight 7, and an equidistant variable groove 8; the melting section is respectively provided with a liquid phase tank 9, a liquid phase flight 10, and a melting tank 11. and the melting distance variable tank 12; the mixing section is respectively provided with a solid phase tank 13, a solid phase screw flight 14, a mixing screw flight 15 and a mixing tank 16.

In this way, when working, the PVC powder enters the material inlet 2 after being stirred and mixed, and is preheated through the stream inlet 2 to the preheating section 3. After preheating, it is extruded in the extrusion groove set in the extrusion section 4 into a linear shape, and split into two smaller strands through the splitter groove 5, wherein the two strands respectively enter the splitter main screw flight 6 and the splitter secondary screw flight 7, and are respectively formed by the equidistant gradually changing grooves 8 Two strands with equal spacing, then respectively enter the liquid phase tank 9 and the liquid phase screw flight 10 for heating and liquefaction, after liquefaction, enter the melting tank 11 for melting, after the linear raw materials are melted, they pass through the melting distance variable tank Change the pitch, and finally enter the solid phase tank 13 and solid phase flight 14 for curing. After curing, knead into linear PVC plastic through the mixing flight 15 and mixing tank 16 and then output, thereby completing the screw extrusion process.

Or, from the preheating section to the mixing end, the shape of the screw in this embodiment is set to a gradually larger cone shape, that is, from the preheating section to the extrusion section, then to the split section, then to the melting section, and finally to the mixing section. The section, the shape of the screw is gradually enlarged, so that the shape of the screw is gradually enlarged to adapt to different extrusion stages, so that the quality of the output wire is better.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model should be included in the utility model. within the scope of protection.
