Abstract
Description
Technical Field
[0001] This utility model relates to the field of molding extruder technology, specifically to a uniform molding extruder for plastic extrusion. Background Technology
[0002] Magnesium slag refers to the residue left over from the smelting of magnesium ore. Its main components are magnesium oxide and calcium oxide. Magnesium slag contains some heavy metals and impurities. After being screened by a grading and screening device, the heavy metals and impurities in the magnesium slag are removed. The screened magnesium slag is then melted with plastic particles and fed into a mixing and stirring device containing polyolefin polymer materials. After mixing and stirring, high molecular weight polyethylene material is obtained. When molding high molecular weight polyethylene material, a molding extruder is required. The molding extruder is one of the types of plastic machinery. The screw molding extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and uniformly mix the material, which is then formed through a die.
[0003] In existing plastic extrusion molding extruders, materials are usually fed into the molding extruder through a hopper. However, when materials are fed directly into the molding extruder through the hopper, blockages can easily occur at the connection between the hopper and the molding extruder. This makes it difficult for materials to enter the molding extruder evenly, affecting the subsequent extrusion molding effect. Utility Model Content

[0024] Example
[0025] Please see Figures 1 to 4 This embodiment proposes a uniformly distributed molding extruder for plastic extrusion, including a base plate 1, a support base 2, and an extruder body 3. The support base 2 is installed on the upper side of the base plate 1, and two sets of extruder bodies 3 are arranged on the upper side of the support base 2. It also includes a uniformly distributed hopper 4, a feed hopper 5, a stirring mechanism, a feed frame 6, a rack 7, a slide rail 8, a sliding seat 9, a transmission plate 10, a sliding scraper 11, an adjusting mechanism, and a uniformly distributed plate 12. Compared with the existing molding extruders for plastic extrusion, in use, the material usually enters the molding extruder through the feed hopper. However, when the material directly enters the molding extruder through the feed hopper, the material is prone to blockage at the connection between the feed hopper and the molding extruder, making it difficult for the material to enter the molding extruder evenly, affecting the material distribution. To address the issue of material extrusion molding effect, this embodiment utilizes the cooperation of the equalizing hopper 4, the feeding hopper 5, the feeding frame 6, and the equalizing plate 12 to achieve uniform material feeding, ensuring material uniformity and feeding effect. The agitation mechanism agitates the material, reducing the probability of material clogging the discharge pipe and ensuring uniform material entry into the extruder body 3. The rack 7, slide rail 8, sliding seat 9, transmission plate 10, actuating scraper 11, and adjustment mechanism agitate the material on the equalizing plate 12, allowing it to enter the equalizing hopper 4 through the equalizing holes on the equalizing plate 12, thus ensuring uniform material feeding.
[0026] like Figure 1 As shown, a forming mechanism 13 is provided on the upper side of the base plate 1. The extrusion head of the extruder body 3 extends into the forming mechanism 13. The extruder body 3 can extrude the material into the forming mold inside the forming mechanism 13, thereby realizing the extrusion forming of the material.
[0027] like Figure 1 and Figure 3As shown, the equalizing hopper 4 is installed on the upper side of the support base 2. The lower side of the equalizing hopper 4 is connected to two feeding pipes. The bottom end of the feeding pipes is connected to the feeding hopper 5. The bottom end of the feeding hopper 5 is connected to the feeding hopper of the extruder body 3. The equalizing hopper 4 can evenly divide the material and then transport it to the interior of the extruder body 3 through the feeding pipes and the feeding hopper 5, thereby realizing the even feeding of the material.
[0028] like Figure 2 and Figure 4 As shown, the agitation mechanism is mounted on the equalizing hopper 4 via two mounting plates. The agitation mechanism includes an agitation shaft 101 and an agitation rod 102. The feed frame 6 is mounted on the upper side of the equalizing hopper 4. Multiple racks 7 are mounted on the upper side of the feed frame 6. A slide rail 8 is mounted on the other side of the upper side of the feed frame 6. The slide rail 8 is I-shaped. Limiting baffles are mounted on both sides of the slide rail 8. The slide rail 8 can limit the sliding of the sliding seat 9, thereby ensuring the stability of the sliding seat 9 when it slides. The sliding seat 9 is horizontally slidably connected to the slide rail 8. A transmission plate 10 is mounted on one of the two sides of the sliding seat 9. A U-shaped guide post is mounted on the upper side of the feed frame 6. The transmission plate 10 is sleeved on the U-shaped guide post. The U-shaped guide post can limit the movement of the transmission plate 10, thereby ensuring the stability of the transmission plate 10 when it moves. A scraper 11 is installed on the lower side of the transmission plate 10. A V-shaped groove is opened on the lower side of the scraper 11. The lower side of the scraper 11 is triangular. The special design of the scraper 11 can better push the material into the equalization holes opened on the equalization plate 12. The adjustment mechanism is installed on the other side of the transmission plate 10. The adjustment mechanism includes a U-shaped frame 201 and a transmission gear 202. The equalization plate 12 is installed inside the feed frame 6. The equalization plate 12 has multiple equalization holes. The adjustment mechanism can drive the transmission plate 10 to move horizontally, so that the transmission plate 10 drives the scraper 11 to push the material on the equalization plate 12, so that the material can enter the equalization hopper 4 evenly through the equalization holes opened on the equalization plate 12. In this embodiment, the driving components are all forward and reverse motors.
[0029] Working principle:
[0030] After being mixed by the mixing and stirring device, the material enters the inside of the feeding frame 6 and is evenly distributed on the equalization plate 12. At this time, two forward and reverse motors are started simultaneously. The forward and reverse motors located inside the adjustment mechanism drive the rotating shaft to rotate. The rotating shaft drives the transmission gear 202 to crawl back and forth along the rack 7. The transmission gear 202 drives the U-shaped frame 201 to move back and forth horizontally through the rotating shaft. The U-shaped frame 201 drives the agitator scraper 11 to move back and forth through the transmission plate 10. The agitator scraper 11 evenly moves the material on the equalization plate 12 into the equalization hole. After being evenly distributed by the equalization plate 12, the material enters the equalization hopper 4. At this time, the forward and reverse motor located inside the stirring mechanism drives the stirring shaft 101 to rotate. The stirring shaft 101 drives multiple stirring rods 102 to stir the material into the discharge pipe at the same time. Then, the material enters the two sets of extruder bodies 3 through the feeding hopper 5, realizing the even feeding of the material. Then, the operator extrudes and shapes the material through the extruder body 3 and the forming mechanism.
