[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings of the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model, and cannot be understood as limiting the utility model.

[0020] The embodiments of the utility model will be described below according to the overall structure of the utility model.

[0021] Please see Figures 1-4 An adjustable plastic wire drawing device includes a wire drawing machine 1, a heating chamber 2 mounted on the top of the wire drawing machine 1, a discharge port 3 on the side wall of the heating chamber 2, a cooling chamber 4 mounted on the outer wall of the wire drawing machine 1, guide wheels 5 mounted on the inner wall of the cooling chamber 4, a feeding hopper 6 mounted on the top of the wire drawing machine 1, a limit rod 7 mounted on the inner wall of the feeding hopper 6, a return spring 8 mounted on the outer wall of the limit rod 7, a filter screen 9 mounted on the top of the limit rod 7, and a baffle sleeve 10 mounted on the inner wall of the filter screen 9. The guide wheels 5 are evenly distributed around the central axis of the cooling chamber 4 and are movably connected to the cooling chamber 4. The filter screen 9 is connected to the feeding hopper 6 via the return spring 8. The device forms a telescopic structure, with the limiting rod 7 movably connected to the feed hopper 6. The return springs 8 are arranged in a circular array around the central axis of the feed hopper 6, and the baffle sleeve 10 is positioned at the center of the filter screen 9. When plastic granules are poured into the feed hopper 6 via the feed hopper 6, limiting rod 7, return spring 8, filter screen 9, and baffle sleeve 10, pressing the feed hopper 6 causes it to vibrate vertically back and forth due to the elastic force of the return spring 8. This prevents plastic granules from accumulating and clogging on the surface of the filter screen 9, improving feeding efficiency. At the same time, the filter screen 9 filters the plastic granules, preventing large solid impurities from entering the equipment and affecting the wire drawing effect.

[0022] Please see Figures 1-4 An adjustable plastic filament drawing device is disclosed. A positioning rod 11 is installed on the top of the feeding hopper 6, a fixing frame 12 is installed on the top of the positioning rod 11, a servo motor 13 is installed on the top of the fixing frame 12, and a conveying rod 14 is installed at the bottom of the servo motor 13. A filter screen 9 is sleeved with the positioning rod 11, and the positioning rod 11 is welded to the feeding hopper 6. The conveying rod 14 forms a rotating structure with the fixing frame 12 through the servo motor 13, and the outer diameter of the conveying rod 14 matches the inner diameter of the bottom of the feeding hopper 6. With the positioning rod 11, fixing frame 12, servo motor 13, and conveying rod 14, when the filtered plastic granules are at the bottom of the feeding hopper 6, the servo motor 13 is started to drive the conveying rod 14 to rotate and feed the material. By controlling the rotation speed of the conveying rod 14 by controlling the servo motor 13, the feeding speed and the amount of material can be precisely controlled, making it more practical.

[0023] Working Principle: In use, first move the device to the desired position, then inject cooling water into the cooling chamber 4, and pour the plastic granules into the feeding hopper 6. Press the feeding hopper 6 downwards continuously; the feeding hopper 6 vibrates vertically back and forth due to the elasticity of the return spring 8, thus preventing plastic granules from accumulating and clogging on the filter screen 9, improving feeding efficiency. Simultaneously, the filter screen 9 filters the plastic granules, preventing large solid impurities from entering the equipment and affecting the filament drawing effect. When the filtered plastic granules are at the bottom of the feeding hopper 6, the servo motor 13 is started to drive the conveying rod 14 to rotate and feed the material. By controlling the rotation speed of the conveying rod 14, the feeding speed and quantity can be precisely controlled. The plastic granules are then fed into the heating chamber 2 for heating and melting, and then extruded through the outlet 3. The extruded filamentous plastic is placed in the cooling chamber 4 to cool and solidify. Finally, the filamentous material is inserted into the traction machine for dragging, thus completing the device's operation. Content not described in detail in this manual belongs to existing technology known to those skilled in the art.
