Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a melting extrusion mechanism of a plastic wire drawing machine. Background Art

[0002] A plastic wire drawing machine is a machine that forms a fiber-forming polymer melt or gel into a filament. In the production process of plastic filaments, the molten raw material passes through the barrel and enters the metering pump and the filter spinneret to become a single filament. In the entire production process, only by keeping the flow channel unobstructed can a wire with uniform diameter be produced. However, in the existing processing process, the molten raw material contains fine impurities, or the raw material is not completely melted, and small particles are easily present, making it difficult to ensure the fluidity of the molten raw material and unable to meet the needs of different products.

[0003] The existing Chinese patent publication number is: CN209397297U. A melt extrusion mechanism of a plastic wire drawing machine includes a barrel, an extrusion screw rotatably arranged in the barrel, and a drive assembly installed at the front of the barrel and connected to the extrusion screw. 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. The cylindrical mold core is provided with a plurality of discharge ports. The front end of the cylindrical mold core is a closed end, and the rear end of the cylindrical mold core is an open end. The open end is provided with a baffle for closing the annular flow channel. A filter assembly is installed on the cylindrical mold core. The utility model improves the filtering effect of the molten raw material by arranging a filter screen and a filter element on the cylindrical mold core, ensures the smoothness of the flow channel, makes the material evenly stressed, and can produce wires with uniform wire diameters, meeting the needs of different products. At the same time, the barrel and the mold sleeve are coaxially docked, ensuring good fluidity of the material and improving production efficiency.

[0004] Although the above technical solution can ensure the smooth flow of the flow channel, so that the material is evenly stressed, and can produce wires with uniform wire diameters, meeting the needs of different products; at the same time, the barrel and the die sleeve are coaxially connected to ensure good fluidity of the material and improve production efficiency. However, when the material melts and enters the barrel, some fine impurities generated inside will enter the barrel along the pipeline. When some impurities are mixed inside, the quality of the drawn wire produced is low. In order to reduce defective products, it is necessary to remove the impurities inside and improve the production quality. Utility Model Content

[0005] The utility model aims to solve the problem that when the material is melted and then enters the inside of the barrel, some fine impurities generated inside the barrel will enter the inside of the barrel along the pipeline.

[0025] In this embodiment, the molten metal is poured onto the top of the filter plate 106 and the motor 107 is started by a power supply, so that the output end of the motor 107 drives the elliptical disk 108 to rotate. When the elliptical disk 108 rotates on the upper surface of the filter plate 106, the filter plate 106 can move up and down with the cooperation of the first spring 104 and the damper 105 at the bottom. The elliptical disk 108 rotates on its outer surface to make the filter plate 106 reciprocate up and down. When shaking, the molten metal on the upper surface of the filter plate 106 can be vibrated to the top of the silo 103 below. The filter plate 106 can remove impurities inside the molten metal and keep the impurities on the upper surface of the filter plate 106, so that the impurities inside the molten metal are reduced, thereby improving the production quality of wire drawing.

[0026] Embodiment 2, as Figure 1-4As shown, the outer surface of the discharge pipe 101 away from the electric push rod 116 is fixedly connected to a plurality of U-shaped fixing plates 110, and pull rods 114 are movably embedded inside the plurality of U-shaped fixing plates 110, and the ends of the plurality of pull rods 114 close to the discharge pipe 101 are fixedly connected to limit plates 112, and the plurality of limit plates 112 are movably connected to the outer surface of the discharge pipe 101, and the outer surfaces of the plurality of limit plates 112 are fixedly connected to clamping rods 115, and the plurality of clamping rods 115 are movably embedded in the discharge pipe 101, and the outer surfaces of the plurality of limit plates 112 are fixedly connected to second springs 113 away from the plurality of clamping rods 115, and the discharge pipe 101 is movably connected to the inner wall of the plurality of U-shaped fixing plates 110, and the outer surfaces of the porous plates 109 are provided with clamping holes 111, and the plurality of clamping rods 115 are movably embedded in the plurality of clamping holes 111, respectively.

[0027] In this embodiment, the molten metal passes through the feed port 102 inside the silo 103 to reach the inside of the discharge pipe 101, and then the electric push rod 116 is activated by the power supply to push the feed plate 117 to slide in the direction of the porous plate 109 inside the discharge pipe 101. While sliding, the molten metal inside the discharge pipe 101 is pushed to the porous plate 109, and then pushed out through the small holes set inside the porous plate 109.

After removal, the impurities on the surface of the porous plate 109 can be removed, and the pull rod 114 is pulled to align the clamping rod 115 with the clamping hole 111.

[0028] Working principle: When in use, pour the molten metal onto the top of the filter plate 106 and then start the motor 107 through a power supply, so that the output end of the motor 107 drives the elliptical disk 108 to rotate. When the elliptical disk 108 rotates on the upper surface of the filter plate 106, the filter plate 106 can move up and down with the cooperation of the first spring 104 and the damper 105 at the bottom. The elliptical disk 108 rotates on its outer surface to make the filter plate 106 reciprocate up and down. When shaking, the molten metal on the upper surface of the filter plate 106 can be vibrated to the top of the silo 103 below. The filter plate 106 can remove impurities inside the molten metal and keep the impurities on the upper surface of the filter plate 106, so that the impurities inside the molten metal are reduced, thereby improving the production quality of wire drawing. The molten metal passes through the feed port 102 inside the silo 103 to reach the inside of the discharge pipe 101, and then the electric push rod 116 is activated by the power supply to push the feeding plate 117 to slide inside the discharge pipe 101 in the direction of the porous plate 109. While sliding, the molten metal inside the discharge pipe 101 is pushed to the porous plate 109, and then pushed out through the small holes set inside the porous plate 109.

After removal, the impurities on the surface of the porous plate 109 can be removed, and the pull rod 114 is pulled to align the clamping rod 115 with the clamping hole 111. Under the action of the second spring 113, the clamping rod 115 is clamped to the inside of the clamping hole 111. The second spring 113 has a limiting effect on the limiting plate 112, so that the clamping rod 115 is firmly clamped in the inside of the clamping hole 111, so that the porous plate 109 is fixed to the inner wall of the porous plate 109 and continues to be used.
