Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a wire drawing device for plastic processing. Background Technology

[0002] Plastics processing is a collective term for a series of processes that transform synthetic resins or plastics into plastic products. As a crucial production link in the plastics industry, it encompasses numerous steps such as batching, molding, and machining. Plastics fiber drawing, a key branch of the molding process, uses specific equipment to convert plastic raw materials into filamentous products, widely used in plastic woven bags, ropes, and packaging materials. This process typically involves thoroughly mixing the plastic raw materials with various additives, heating and melting them in an extruder, extruding them into fine filaments using a die, then stretching the filaments in a highly elastic state to enhance their strength, and finally cooling and winding them up. Fiber drawing devices for plastics processing have emerged to address this need. These devices integrate multiple technologies such as mechanical transmission, temperature control, and tension adjustment, aiming to precisely control the fiber drawing process, helping plastics processing companies improve production efficiency and meet the growing market demand for plastic products.

[0003] There are various plastic drawing devices on the market. Some traditional drawing machines use polypropylene and high-density ethylene as raw materials, producing flat filaments through heating, extrusion, cooling, and stretching. These devices use cooling water tanks to hold cooling water during the cooling step, with the plastic filaments passing through the tanks. A circulating water pump keeps the cooling water circulating to maintain uniform temperature. However, these devices occupy a large space, have a long output process, are prone to impurities adhering during transport, and are susceptible to filament breakage. Furthermore, they have poor heat dissipation, and the drawn plastic filaments cannot be cooled quickly. Therefore, a new plastic drawing device is proposed to address these problems.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-3An embodiment of this utility model is provided: a wire drawing device for plastic processing, including a base 1, an extruder 2 fixedly connected to the top of the base 1, a cooling box 4 provided on the top of the base 1, a drying box 5 fixedly connected to the top of the base 1, a take-up roller 6 provided on the top of the base 1, a cooling mechanism provided on the top of the base 1, and a screening mechanism provided on the top of the extruder 2.The cooling mechanism includes a water sprayer 15. A water storage tank 7 is fixedly connected to the top of the base 1, providing a stable water source for the cooling system and enabling water recycling. A water pump 12 is fixedly connected to the side wall of the water storage tank 7, and a water pipe 14 is fixedly connected to the output end of the water pump 12. The water pump 12 provides power for water circulation, transporting water from the water storage tank 7 to the water sprayer 15 and other components. The bottom of the cooling tank 4 is fixedly connected to the top of the water storage tank 7, forming a compact integrated structure that saves space and facilitates the recycling of cooling water. The cooled water can be directly returned to the water storage tank 7. The bottom of the water sprayer 15 is fixedly connected to the top of the cooling tank 4, allowing the cooling water to be directly... The water is sprayed onto the target object inside the cooling tank 4 to improve cooling efficiency. One end of the water supply pipe 14 is fixedly connected to the inside of the sprayer 15, which has multiple nozzles 16 fixedly connected inside. These nozzles increase the spray area and uniformity of the cooling water, ensuring the target object's surface is fully in contact with the cooling water, improving the consistency of the cooling effect, and ensuring a uniform temperature drop across all parts of the object. A filter screen 10 is installed at the bottom of the cooling tank 4 to filter impurities and particles from the cooling water, preventing these impurities from entering the water storage tank 7 or the circulation system. This avoids clogging or wear on components such as the water pump 12 and nozzles 16, extending the equipment's service life and ensuring the normal operation of the cooling system. Cooling tank 4... An internally rotating wiper roller 11 is connected to the drying chamber 5. The wiper roller 11 can roll on the surface of the object to remove residual cooling water, accelerating moisture evaporation and improving drying efficiency. A cooler 13 is fixedly connected inside the water storage tank 7 to cool the water in the tank, lowering the temperature of the cooling water and enhancing the cooling effect. A fan 17 is fixedly connected inside the drying chamber 5. The airflow generated by the fan 17 accelerates the evaporation of moisture from the object's surface, further drying the object and shortening the drying time. Air outlets 18 are opened on both sides of the drying chamber 5, allowing air to circulate within the chamber, ensuring smooth airflow and improving the uniformity of the drying effect. Multiple rotating connections are also present inside the drying chamber 5. Each conveyor roller 9 is arranged in a W-shape inside the drying chamber 5. This W-shaped arrangement extends the conveying path of the object within the drying chamber 5, increases the contact time between the object and air, improves the drying effect, and ensures thorough drying. The compact layout also saves space. An outlet pipe 31 is fixedly connected inside the extruder 2. Conveyor pipes 8 are fixedly connected to both sides of the cooling chamber 4. One conveyor pipe 8 corresponds to the outlet pipe 31, and the other corresponds to the drying chamber 5. The conveyor pipes 8 provide a conveying channel for the material, allowing it to smoothly enter and exit the cooling chamber 4, while protecting the material from external interference during transport, ensuring material quality and conveying efficiency.

[0037] Reference Figure 1 , Figure 4 and Figure 5The screening mechanism includes a screening plate 26. A screening box 3 is fixedly connected to the top of the extruder 2. The screening plate 26 is located inside the screening box 3, which provides a closed working space for the screening process to prevent material splashing. A screening seat 25 is fixedly connected to the top of the extruder 2. A second motor 27 is fixedly connected to the top of the screening seat 25. An eccentric wheel 28 is fixedly connected to the output end of the second motor 27. The side wall of the eccentric wheel 28 is in contact with the top of the screening plate 26. The eccentric wheel 28 converts the rotational motion of the second motor 27 into the reciprocating vibration of the screening plate 26. The unbalanced force generated by the eccentric structure causes the screening plate 26 to vibrate regularly, promoting the material to pass through the screening plate 26. The screen plate 26 moves upwards and performs screening. A spring 29 is installed at the bottom of the screen plate 26. One end of the spring 29 is fixedly connected to the bottom of the screen plate 26, and the other end is fixedly connected to the top of the screen base 25. The spring 29 provides elastic support and a restoring force for the screen plate 26. When the eccentric wheel 28 drives the screen plate 26 to vibrate, the spring 29 acts as a buffer and damper, reducing the force on the screen base 25 and helping the screen plate 26 to quickly return to its original position, maintaining a stable vibration state. A movable block 30 is rotatably connected to one side of the screen plate 26. The bottom of the movable block 30 is fixedly connected to the top of the screen base 25, fixing the movable block 30 to the screen base 25 and ensuring its stable position. The rotation fulcrum of the screening plate 26 is fixed to ensure that the screening plate 26 will not shift during vibration, maintaining the normal operation of the screening mechanism. A collection box 24 is slidably connected inside the screening box 3, and the side wall of the collection box 24 is slidably connected to the side wall of the screening seat 25. The collection box 24 is used to collect the screened material. The sliding connection facilitates the removal, cleaning, or replacement of the collection box 24, ensuring that the screened material can be collected and processed in a timely manner, improving production efficiency and keeping the inside of the screening box 3 clean. A conveying cylinder 23 is fixedly connected inside the screening box 3, and a feeding hopper 19 is fixedly connected to the top of the conveying cylinder 23, ensuring that the material can enter the screening area evenly and continuously, making the screening process sustainable. Continuing, a fixed frame 21 is fixedly connected to the inner wall of the conveying cylinder 23, and a motor 20 is fixedly connected to the side wall of the fixed frame 21. The fixed frame 21 provides a mounting support point for the motor 20, ensuring that the position of the motor 20 is stable during operation and that the motor 20 can reliably drive the auger blade 22 to rotate. The output end of the motor 20 is fixedly connected to the auger blade 22, which is located inside the conveying cylinder 23. Using the propulsive action of the spiral blade, the material is conveyed along the conveying cylinder 23 to the top of the screening plate 26, realizing the directional conveying of the material. The conveying cylinder 23 is located directly above the screening plate 26, so that the material can fall directly onto the screening plate 26 after being output from the conveying cylinder 23.

[0038] Working principle: First, plastic granules are poured into the feeding hopper 19. Then, motor 20 is started, which drives the auger blade 22 to rotate, slowly feeding the plastic granules through the conveying cylinder 23. The plastic granules then fall from the conveying cylinder 23 onto the screening plate 26. At this time, motor 27 drives the eccentric wheel 28 to rotate. When the eccentric wheel 28 rotates, it briefly contacts the screening plate 26, causing one side of the screening plate 26 to press down. The other side of the screening plate 26 is fixed in place by the movable block 30. As the eccentric wheel 28 continuously and briefly presses down on the screening plate 26, the screening plate 26 bounces up through the spring 29 at the bottom. This continuous shaking achieves the effect of screening the plastic granules. The screened plastic granules fall through the screening seat 25 into the extruder 2 for processing. The granules that do not pass through are shaken into the collection box 24. After the collection box 24 is full, it can be pulled out and cleaned using the handle on top, and then pushed back in for processing. The plastic filaments are discharged through the discharge pipe 31 and input through the feed pipe 8 on the cooling box 4. They are then conveyed by the conveying roller 9. At this time, the water pump 12 delivers water from the water storage tank 7 to the water sprayer 15 through the water supply pipe 14. Multiple nozzles 16 are provided to spray water onto the plastic filaments to cool them down. The falling water flows back into the water storage tank 7 through the filter screen 10. The cooler 13 continuously cools the water in the water storage tank 7 to keep the water temperature at a low level. After the plastic filaments are cooled by the water spraying, most of the surface moisture is scraped off by the scraper roller 11. Then the plastic filaments enter the drying box 5. The fan 17 starts to blow air onto the plastic filaments. Multiple conveying rollers 9 in the drying box 5 are arranged in a W shape to maximize the flow of air from the fan 17. The air outlets 18 on both sides of the drying box 5 disperse the blown air to reduce the possibility of conveying deviation. After drying, the plastic filaments are taken in by the take-up roller 6.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
