[0002] The plastic wire drawing machine uses polypropylene and high-density ethylene as raw materials. After heating, extrusion, splitting and stretching, flat wire is formed and then wound up for weaving on the circular loom. In the plastic wire drawing process, the demand for high-quality plastic wire requires that the raw materials can be fully melted and evenly extruded to ensure the dimensional accuracy, mechanical properties and appearance quality of the plastic wire.

[0003] After searching, the document of announcement number "CN209397297U" mentioned "a melt extrusion mechanism of a plastic wire drawing machine, comprising a barrel, an extrusion screw rotatably arranged in the barrel, and a protective component installed at the front of the barrel and connected to the extrusion screw in a transmission manner, a mold sleeve coaxially docked with the barrel is provided at the rear of the barrel, a cylindrical mold core coaxially arranged with the barrel is fixedly connected in the mold sleeve, an annular flow channel is formed between the cylindrical mold core and the mold sleeve, a plurality of discharge ports are provided on the cylindrical mold core, the front end of the cylindrical mold core is a closed end, the rear end of the cylindrical mold core is an open end, a baffle for closing the annular flow channel is provided at the open end, and an adjusting component is installed on the cylindrical mold core. The utility model improves the filtering effect of the molten raw material by arranging a guide tube and a filter element on the cylindrical mold core, ensures the smooth flow channel, and makes the material affected. The force is evenly distributed, producing yarns with uniform diameters, meeting the needs of different products. Furthermore, the coaxial connection between the barrel and the die sleeve ensures good material fluidity and improves production efficiency. During use, the device incorporates a flow guide tube and filter element on the cylindrical die core to enhance the filtration of the molten raw material, ensuring a smooth flow path and evenly distributing force on the material. This allows for the production of yarns with uniform diameters, meeting the needs of different products. Furthermore, the coaxial connection between the barrel and the die sleeve ensures good material fluidity and improves production efficiency. The design is simple, reasonable, and highly efficient. However, this device lacks a temperature control mechanism. This poses the risk of poor plasticization and fluidity of the plastic resulting from excessively low temperatures, preventing normal extrusion, or degradation of the plastic due to excessively high temperatures, failing to guarantee the molding performance and quality of the finished product.

[0004] To this end, we provide a melt extrusion mechanism for a plastic wire drawing machine to solve the above problems. Utility Model Content

[0005] The present application provides a melt extrusion mechanism for a plastic wire drawing machine, which solves the problem that the utility model lacks a temperature control structure, resulting in poor plasticization and poor fluidity of the plastic due to too low a temperature, and inability to extrude normally, or degradation of the plastic due to too high a temperature, and inability to guarantee the molding performance and quality of the product.

[0006] The present application provides a melt extrusion mechanism of a plastic wire drawing machine, comprising a main body and a temperature control mechanism, wherein the temperature control mechanism is installed on the outer side of the main body;

[0007] The temperature control mechanism includes a heating component installed on the outside of the main body, a protective component installed on the outside of the heating component, a cooling component installed inside the main body, and an adjusting component installed on one end of the cooling component.

[0008] Preferably, the heating assembly comprises a resistance heating coil fixedly connected to the outside of the main body, and a ceramic fiber insulation layer is fixedly connected to the outside of the resistance heating coil.

[0009] Preferably, the protective assembly includes a protective shell fixedly connected to the outside of the ceramic fiber insulation layer, and the outside of the protective shell is fixedly connected to a support frame.

[0010] Preferably, the cooling assembly includes a metal heat pipe fixedly connected to the interior of the main body, and a temperature sensor is installed on the surface of the main body.

[0011] Preferably, the regulating assembly comprises a pump installed at one end of the metal heat conducting pipe, and a flow guide pipe is installed on one side of the pump.

[0012] Preferably, connecting components are installed at both ends of the main body, and the connecting components include an L-shaped feeding pipe threadedly connected to one end of the main body, and the other end of the main body is threadedly connected to an extrusion die.

[0013] Preferably, an extrusion assembly is installed on the inner side of the L-shaped feed tube, and the extrusion assembly includes an extrusion screw rotatably connected to the inner side of the L-shaped feed tube, and one end of the extrusion screw is connected to a drive motor via a flat key.

[0014] It can be seen from the above technical solution that the present application provides a melt extrusion mechanism of a plastic wire drawing machine. When in use, first, the plastic wire drawing machine discharge pipe is connected through an L-shaped feed pipe, and the material enters the inside of the main body through the L-shaped feed pipe. Then, the extrusion screw is driven by the driving motor to rotate to extrude the material, and the material is shaped and discharged by the extrusion mold. The extrusion mold can be quickly replaced with different models by rotating the thread according to demand. Then, the main body temperature is transmitted back to the control end in real time through the temperature sensor. The user adjusts the temperature through the parameters. When the temperature needs to be increased, the resistance heating ring is started to heat the main body, thereby increasing the temperature of the raw material flowing in the main body. The ceramic fiber insulation layer reduces heat dissipation and reduces the impact of high temperature on external components. Then, when cooling is required, the guide pipe is connected to the external water source, and the water flow intensity is controlled by the pump. The water flow passes through the metal heat pipe to quickly absorb and discharge the heat of the main body, thereby quickly cooling down. Finally, the protective shell provides protection for the internal structure, and the support frame provides support for the structure, completing the use of a melt extrusion mechanism of a plastic wire drawing machine.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The temperature control mechanism avoids problems such as poor plasticization and fluidity of plastics due to low temperature, which makes it impossible to extrude them normally, or degradation of plastics due to high temperature, thereby ensuring the molding performance and quality of the products. The temperature of the main body is transmitted back to the control end in real time through the temperature sensor. The user adjusts the temperature through the parameters. When the temperature needs to be increased, the resistance heating ring is started to heat the main body, thereby increasing the temperature of the raw materials flowing in the main body. The ceramic fiber insulation layer reduces heat dissipation and reduces the impact of high temperature on external components. When the temperature needs to be lowered, the guide pipe is connected to the external water source, and the water flow intensity is controlled by the pump. The water flows through the metal heat pipe to quickly absorb and discharge the heat of the main body, thereby quickly cooling the temperature. The protective shell provides protection for the internal structure, and the support frame provides support for the structure.

[0017] 2. The material is connected to the discharge pipe through the L-shaped feed pipe. The material enters the main body through the L-shaped feed pipe. The extrusion screw is driven by the drive motor to rotate and extrude the material. The material is shaped and discharged by the extrusion die. The extrusion die can be quickly replaced with different models by rotating the thread according to demand.

[0018] To sum up, the present application not only avoids problems such as poor plasticization and poor fluidity of plastics due to low temperature, inability to extrusion normally, or degradation of plastics due to high temperature through the temperature control mechanism, thereby ensuring the molding performance and quality of the product, but also the extrusion mold can be quickly replaced with different models by rotating the thread according to needs.
