Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a uniform heating component and an extruder. Background Technology

[0002] An extruder is an important piece of plastic processing equipment, widely used in the manufacture of various plastic products. Its main function is to use the pressure and shear force generated by the rotation of the screw to fully plasticize and uniformly mix the material, which is then shaped through a mold. This equipment can be used not only to manufacture plastic products, but also widely used in the production of molded products in other industries such as metal, food, and pharmaceuticals.

[0003] However, current extruders still have the following shortcomings. For example, patent application number 202321381498.1 discloses an extruder with an adjustment function. This extruder with an adjustment function, through the coordinated use of a machine base, extruder, feed port, discharge device, positioning block, adjustment mechanism, and positioning mechanism, facilitates adjustment and replacement by operators when adjusting the discharge device, thereby increasing its processing efficiency. However, during use, it cannot heat the material evenly and fully, affecting the heating effect. Furthermore, after heating, the device cools down slowly, which can easily cause burns to operators.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a uniform heating component and an extruder. Utility Model Content

[0014] This utility model provides a uniform heating component and an extruder, which have the following beneficial effects:

[0015] 1. This utility model incorporates a temperature control component, which includes a water storage tank, a cooler, a high-pressure water pump, a water delivery pipe, a heating pipe, a drain valve, a protective layer, and a water inlet jacket. In use, the high-pressure water pump is activated to extract water from the storage tank and deliver it to the water inlet jacket via the water delivery pipe. The cooler is activated to cool the remaining water in the storage tank. Simultaneously, the heating pipe, when energized, heats the extrusion can, thereby heating the water in the water inlet jacket. Through the water inlet jacket, the material in the extrusion chamber is heated evenly, ensuring uniform heating. After extrusion, the drain valve is opened to drain the hot water. The high-pressure water pump is then activated again to deliver cooled water to the water inlet jacket via the water delivery pipe, increasing the cooling speed of the extrusion can. This allows the device to heat the material evenly, improving the heating effect and enabling rapid cooling of the extrusion can, preventing burns to operators.

[0016] 2. This utility model incorporates a feeding assembly, which includes a feeding hopper, a first filter frame, a second filter frame, a support plate, a rotating motor, a rotating shaft, and a stirring rod. In use, material is fed into the extrusion chamber of the extruder through the feeding assembly. When the material enters the feeding hopper, it first passes through the first filter frame to filter out larger, defective materials. The second filter frame further intercepts and filters out defective materials, maintaining the quality of the raw materials. Simultaneously with the feeding, the rotating motor is activated, causing the rotating shaft to rotate, which in turn drives the stirring rod to rotate, constantly agitating the material and ensuring smooth feeding. This allows the device to screen out defective materials and maintain smooth feeding, preventing blockages. Attached Figure Description

A support frame 2 is provided on the right side of the upper surface of the base plate 1, and an extrusion tank 3 is installed on the inner end surface of the support frame 2. The extrusion tank 3 is an integrally formed steel structure. The temperature control component 4 is located on the upper surface of the base plate 1 and includes a water storage tank 401, a cooler 402, a high-pressure water pump 403, a water supply pipe 404, a heating pipe 405, a drain valve 406, a protective layer 407, and a water inlet jacket 408. The water storage tank 401 is located on the upper surface of the base plate 1, and the cooler 402 is installed on the right surface of the water storage tank 401. The high-pressure water pump 403 is installed on the rear side of the water storage tank 401, and the output end of the high-pressure water pump 403 is connected to...

The protective layer 407 and the water inlet jacket 408 are tightly connected. A water recovery tank 5 is installed at the output end of the drain valve 406. A water pump 6 is provided on the right side of the water recovery tank 5. A water recovery pipe 7 is connected to the output end of the water pump 6. The output end of the water recovery pipe 7 passes through the upper surface of the water storage tank 401 and extends into the interior of the water storage tank 401.

[0024] The specific operation is as follows: When in use, start the high-pressure water pump 403 to draw water out of the water storage tank 401 and transport the water to the water inlet jacket 408 through the water delivery pipe 404. Start the cooler 402 to cool the remaining water in the water storage tank 401. At the same time, the heating pipe 405 will heat the extrusion tank 3 after being energized, and then heat the water in the water inlet jacket 408. Through the water inlet jacket 408, the material in the extrusion chamber 13 can be heated evenly, so that the material is heated evenly. After the material is extruded, open the drain valve 406 to discharge the hot water to the recycling water tank 5. Start the high-pressure water pump 403 again to transport the cooled cold water to the water inlet jacket 408 through the water delivery pipe 404 to increase the cooling speed of the extrusion tank 3. After the cold water is drawn out, start the water pump 6 to transport the hot water in the recycling water tank 5 to the water storage tank 401 through the recycling water pipe 7, thereby realizing the recycling of water.

[0025] like Figures 2 to 4As shown, an extruder includes a support base 8 and a feeding assembly 10. A protective cover 9 is installed on the top of the support base 8, and the right surface of the protective cover 9 is connected to the left surface of the extrusion tank 3. The feeding assembly 10 is disposed on the upper surface of the extrusion tank 3 and includes a feeding hopper 1001, a first filter frame 1002, a second filter frame 1003, a support plate 1004, a rotating motor 1005, a rotating shaft 1006, and a stirring rod 1007. The feeding hopper 1001 is disposed on the upper left side of the extrusion tank 3, and the first filter frame 1002 is installed at the upper end of the inside of the feeding hopper 1001. A second filter frame 1003 is disposed below the first filter frame 1002. The filter frame 1003 and the protective cover 9 are equipped with a support plate 1004 on the upper surface. A rotating motor 1005 is provided on the left surface of the support plate 1004. The output end of the rotating motor 1005 is connected to a rotating shaft 1006 through a coupling. The rotating shaft 1006 passes through the surface of the feed hopper 1001 and extends into the feed hopper 1001. An agitator 1007 is installed on the surface of the rotating shaft 1006. A servo motor 11 is installed inside the protective cover 9. The output end of the servo motor 11 is connected to a conveying auger 12 through a coupling. An extrusion chamber 13 is provided on the inner surface of the water inlet jacket 408. An extrusion port 14 is installed on the right side of the extrusion chamber 13.

[0026] The specific operation is as follows: During use, the material is fed into the extrusion chamber 13 inside the extrusion tank 3 through the feeding component 10. When the material enters the feeding hopper 1001, it will first pass through the first filter frame 1002 to filter out larger unqualified materials. The second filter frame 1003 can further intercept and filter unqualified materials to maintain the quality of the raw materials. At the same time as the material is fed, the rotating motor 1005 is started, which drives the rotating shaft 1006 to rotate. Then, the rotating shaft 1006 drives the stirring rod 1007 to rotate, which keeps the material agitated and keeps the feeding smooth. At the same time as the material enters the extrusion chamber 13, the servo motor 11 is started, which drives the conveying auger 12 to rotate and convey the material. The heated material is then conveyed to the extrusion port 14 for extrusion.

[0027] In summary, as Figures 1 to 3As shown, in use, the uniform heating assembly and extruder work as follows: First, the high-pressure water pump 403 is started to draw water from the water storage tank 401 and transport it to the water inlet jacket 408 through the water pipe 404. The cooler 402 is then started to cool the remaining water in the water storage tank 401. Simultaneously, the heating pipe 405 is energized to heat the extrusion tank 3, thereby heating the water in the water inlet jacket 408. This heat evenly heats the extrusion chamber 13. Then, material is fed into the extrusion chamber 13 of the extrusion tank 3 through the feeding assembly 10. When the material enters the feeding hopper 1001, it first passes through the first filter frame 1002 to filter out larger, defective materials. The second filter frame 1003 further intercepts and filters out defective materials, maintaining the quality of the raw materials. Simultaneously with the feeding... The rotating motor 1005 is started, causing the rotating shaft 1006 to rotate. The rotating shaft 1006 then drives the stirring rod 1007 to rotate, constantly agitating the material and ensuring smooth feeding. As the material enters the extrusion chamber 13, the servo motor 11 is started, causing the servo motor 11 to drive the conveying auger 12 to rotate, conveying the material. The heated material is then conveyed to the extrusion port 14 for extrusion. After the material is extruded, the drain valve 406 is opened to discharge the hot water to the recycling water tank 5. The high-pressure water pump 403 is started again, and the cooled cold water is delivered to the water inlet jacket 408 through the water pipe 404 to increase the cooling speed of the extrusion tank 3. After the cold water is extracted, the water pump 6 is started again, and the water pump 6 delivers the hot water in the recycling water tank 5 to the storage tank 401 through the recycling water pipe 7, thereby realizing the recycling of water.
