Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically to a plastic extruder capable of uniform feeding. Background Technology

[0002] A plastic extruder is an important piece of plastic processing equipment, mainly used in a continuous production process of heating, plasticizing, and extruding plastic raw materials. Extruders originated in the 18th century and were initially used to manufacture seamless lead pipes and other items.

[0003] Chinese utility model patent CN218985693U discloses a plastic extruder, relating to the field of plastic production technology. The extruder includes a conveyor cylinder with a feed hopper mounted on one side of its top. A feeding screw is installed inside the conveyor cylinder, and an end cap is mounted at one end of the cylinder. An extrusion port is located at the end of the end cap. A discharge baffle is installed inside the conveyor cylinder below the feed hopper, and a connecting shaft is installed through the discharge baffle. The bottom of the connecting shaft is connected to the feeding screw. A stirring blade is mounted on the top of the connecting shaft inside the feed hopper, and a scraper is rotatably fitted outside the extrusion port. This utility model utilizes the rotation of the feeding screw to drive the stirring blade in the feed hopper, which not only disperses the plastic particles but also prevents clogging of the feed hopper. Simultaneously, the feeding screw can also drive a lever to rotate, pushing a flexible telescopic rod, which in turn drives the scraper to rotate at the extrusion port, scraping off any remaining plastic material at its edge. This automatically cleans the plastic material adhering to the extrusion port, resulting in good performance.

Detailed Implementation

[0026] 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.

[0027] Example 1: Please refer to Figures 1-5 Existing plastic extruders are not easy to feed materials evenly when feeding them into the extruder. In order to solve this technical problem, this embodiment discloses the following technical content;

[0028] A plastic extruder capable of uniform feeding has support legs 2 fixedly connected to both sides of the lower left side surface of the outer casing 1, and a feed pipe 3 fixedly connected to the top left side of the outer casing 1. A mounting frame 4 is fixedly connected to the middle of the upper surface of the feed pipe 3, and a first motor 5 is fixedly connected to the middle of the upper surface of the mounting frame 4. A stirring rod 6 is fixedly connected to the output shaft of the first motor 5, and a scraper 7 is fixedly connected to the outer side of the lower end of the stirring rod 6. The outer side of the scraper 7 is in contact with the inner side of the feed pipe 3. An automatic telescopic rod 8 is fixedly connected to both the front and rear ends of the upper surface of the mounting frame 4, and the output shaft of the automatic telescopic rod 8 is fixedly connected to the top cover 9. A second motor 10 is fixedly connected to the middle left side of the outer casing 1, and a screw conveyor 11 is fixedly connected to the output shaft of the second motor 10.

[0029] When feeding materials into the outer shell 1, the second motor 10 is started first to prevent all materials from accumulating at the left end of the inner shell 1. Then, the automatic telescopic rod 8 is started, causing the output end of the automatic telescopic rod 8, along with the top cover 9, to move upward within the mounting frame 4, exposing the top of the feed pipe 3. The materials are then fed into the inner shell 1 through the opening at the top of the feed pipe 3. The first motor 5 is then started, causing the output shaft of the first motor 5 to rotate with the stirring rod 6 and the scraper 7 to stir the materials in the feed pipe 3, preventing material accumulation. The scraper 7 scrapes off the materials adhering to the inner wall of the feed pipe 3, preventing the materials from sticking to the inner wall of the feed pipe 3. When feeding materials, the output shaft of the second motor 10 rotates the screw conveyor 11 inside the outer shell 1. When the screw conveyor 11 rotates, it conveys the materials to the right end of the inner shell 1. Since the outer side of the screw conveyor 11 is in contact with the inner side of the outer shell 1, it prevents the materials from sticking to the inner wall of the outer shell 1. The above are the steps for feeding materials evenly and conveying the materials in the outer shell 1 to the right end of the inner shell 1.

[0030] Example 2: In existing plastic extruders, the plastic cools down during the conveying process due to insufficient temperature, making it difficult to heat evenly and prevent the plastic from cooling down. Therefore, this example uses the following technical solution, such as... Figures 1-4 and Figure 6 As shown;

[0031] The discharge mechanism is composed of a discharge pipe 12, a third motor 13, a side plate 14, a clamping block 15, and a baffle 16. The third motor 13 is fixedly connected to the right end of the upper surface of the discharge pipe 12, and the output shaft of the third motor 13 is fixedly connected to the side plate 14. The left side of the side plate 14 is in contact with the right side of the discharge pipe 12. The clamping block 15 is fixedly connected to the middle of the front side of the side plate 14. The baffle 16 is fixedly connected to the middle of the right end of the front side of the discharge pipe 12. An arc-shaped groove is opened on the rear side of the right end of the baffle 16, and the arc-shaped groove opened on the rear side of the right end of the baffle 16 is engaged with the clamping block 15.

[0032] After the material is conveyed to the right end of the inner shell 1 by the screw conveyor 11, it can be extruded from the discharge pipe 12. At this time, the third motor 13 is started. The output shaft of the third motor 13 rotates the side plate 14, so that the side plate 14 rotates to the upper end of the discharge pipe 12, completely exposing the right side of the discharge pipe 12. The extruded material can be discharged from the discharge pipe 12. After the material is extruded, the side plate 14 needs to be closed on the right side of the discharge pipe 12 again. At this time, the third motor 13 is started. The output shaft of the third motor 13 rotates the side plate 14 in the opposite direction until the locking block 15 on the side plate 14 engages with the slot opened on the rear right side of the baffle 16. At this time, the side plate 14 is completely closed on the right side of the discharge pipe 12 to prevent material from being discharged from the discharge pipe 12.

[0033] The heating mechanism is composed of an inner shell 17, a heating tube 18, an outer shell 19, and a heat insulation cavity 20. The heating tube 18 is fixedly connected to the inner side of the inner shell 17, and the outer shell 19 is fixedly connected to the outer side of the inner shell 17. The outer end of the inner side of the outer shell 19 is fixedly connected to the outer side of the outer shell 1 at equal angles by several sturdy bolts. A heat insulation cavity 20 is formed between the inner shell 17 and the outer shell 19.

[0034] During the process of conveying plastic inside the outer shell 1, the plastic needs to be heated to prevent it from cooling and solidifying. Therefore, when conveying plastic, the heating tube 18 needs to be activated to heat the plastic inside the outer shell 1. Since the heating tube 18 is wrapped around the outside of the outer shell 1, it can heat the plastic inside the outer shell 1 evenly. Since an outer shell 19 is provided on the outside of the inner shell 17, a heat insulation cavity 20 is formed between the inner shell 17 and the outer shell 19, which can prevent the outer temperature of the outer shell 19 from being too high and causing injury to the staff if they accidentally touch it.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
