Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically to a plastic extruder with anti-clogging feed mechanism. Background Technology

[0002] Plastic extruders are crucial equipment in the plastics manufacturing industry, widely used for processing various plastic products such as pipes, sheets, and profiles. Their working principle involves using the pressure and shear force generated by the rotating screw to melt and continuously extrude the plastic raw material, forming plastic products of specific shapes. During the hot-melt process of plastic production, the feeding stage of the plastic extruder often faces clogging problems, necessitating anti-clogging measures for the feed pipe and inlet.

[0003] During storage and transportation, plastic raw materials may become damp and clump together, causing the particles to stick together. A large number of small clumps can easily accumulate. When these clumps of raw material enter the feed inlet of the extruder, they tend to pile up and obstruct the feed channel. When a large number of clumps accumulate together, localized accumulation can easily form at the feed inlet, leading to blockage. Furthermore, after the plastic is blocked, the feed uniformity is easily insufficient, which may result in uneven wall thickness after the pipe is discharged, causing local defects and seriously affecting the performance and safety of the product. To address these issues, we propose a plastic extruder with anti-clogging feed mechanism. Utility Model Content

[0026] Please see Figures 1-5 A plastic extruder with anti-clogging feed includes a plastic extruder body 1 and a feed cylinder 2, wherein the feed cylinder 2 is connected to the top of the plastic extruder body 1;

[0027] The top of the feed cylinder 2 is provided with a support frame 3, the bottom of the support frame 3 is connected to a stirring drive column 4, the top of the support frame 3 is provided with a stepper motor 5, the top of the stirring drive column 4 is connected to the output end of the stepper motor 5, and the stirring drive column 4 is provided with an anti-clogging stirring plate 6.

[0028] The top of the side of the feed cylinder 2 is provided with a feed pipe 7, the top of the feed pipe 7 is provided with an expansion feed hopper 8, the side of the feed cylinder 2 away from the feed pipe 7 is provided with an exhaust guide pipe 9, and the top of the exhaust guide pipe 9 is provided with an exhaust fan 10.

[0029] The beneficial effects of this solution are as follows: By providing a support frame 3 inside the feed cylinder 2, a stepper motor 5 and a stirring drive column 4 can be supported. The stepper motor 5 drives the stirring drive column 4, which in turn drives the anti-clogging stirring plate 6 to uniformly break up and mix the plastic raw materials that accumulate and clump inside the feed cylinder 2, preventing material accumulation and ensuring uniform and stable feeding. After the raw materials are placed into the expanded feed hopper 8, they are introduced into the feed cylinder 2 through the feed pipe 7. The exhaust guide pipe 9 on the side of the feed cylinder 2 assists in the air extraction and introduction, making it less likely for small clumps of material to accumulate and clog the feed pipe 7. The material is introduced more conveniently, giving the device anti-clogging stirring ability, breaking up and stirring small clumps of particles, preventing feeding blockage, ensuring uniform and stable feeding, and resulting in high uniformity and quality of output.

[0030] Furthermore, a connecting plate 11 is provided at the bottom of the inner side of the feed cylinder 2, and an anti-clogging block 12 is provided in the middle of the connecting plate 11. The anti-clogging block 12 is located directly below the stirring drive column 4.

[0031] By setting the connecting plate 11 and the anti-blocking block 12, the connecting plate 11 can support and bear the anti-blocking block 12, and the anti-blocking block 12 can prevent accumulation on the bottom of the inner side of the feed cylinder 2. The clumped raw materials can be supported by the anti-blocking block 12 to prevent the arching effect, which is convenient for preventing accumulation and blockage.

[0032] Furthermore, the anti-clogging block 12 is arc-shaped, and an oil seal is provided at the connection between the stirring drive column 4 and the support frame 3;

[0033] The anti-clogging block 12 is an arc-shaped sphere to prevent the raw materials from accumulating due to the arch bridge effect, and has a good anti-clogging effect. When the stirring drive column 4 rotates, it can be supported by the oil seal, and has good adaptability.

[0034] Furthermore, multiple anti-clogging stirring blades 6 are evenly distributed in a ring shape around the stirring drive column 4, and the anti-clogging stirring blades 6 are in contact with the inner wall of the feed cylinder 2.

[0035] By setting multiple anti-clogging stirring blades 6 evenly distributed in a ring shape around the stirring drive column 4, the stirring drive column 4 can drive the anti-clogging stirring blades 6 to stably and evenly crush and mix the raw materials, with good anti-caking effect and excellent adaptability.

[0036] Furthermore, both the feed pipe 7 and the exhaust guide pipe 9 are L-shaped, with the bottom end of the feed pipe 7 being higher than the bottom end of the exhaust guide pipe 9.

[0037] By setting both the feed pipe 7 and the exhaust guide pipe 9 to be L-shaped, the material is guided stably, and the exhaust guide pipe 9 is not easy to enter the raw material, which has a good anti-clogging effect. In addition, the bottom end of the feed pipe 7 is higher than the bottom end of the exhaust guide pipe 9, so when the exhaust guide pipe 9 is drawn by the exhaust fan 10, the raw material in the feed cylinder 2 can be driven by the wind, which can stably discharge the material and prevent it from clogging in the feed pipe 7, making it practical.

[0038] Furthermore, the bottom end of the exhaust guide pipe 9 extends to the inner side of the feed cylinder 2, and the inner wall of the feed cylinder 2 is provided with a leak-proof and breathable mesh 13, with the bottom end of the exhaust guide pipe 9 corresponding to the position of the leak-proof and breathable mesh 13.

[0039] By providing a leak-proof and breathable mesh 13 on the inner wall of the feed cylinder 2, and the leak-proof and breathable mesh 13 corresponding to the bottom end of the exhaust guide pipe 9, the exhaust guide pipe 9 can draw air and guide the raw material, while the raw material can be blocked by the leak-proof and breathable mesh 13, making it less likely to leak out, and the flow guidance is stable.

[0040] Furthermore, the top of the feed cylinder 2 is threaded with a sealing cover plate 14, and the bottoms of both the feed cylinder 2 and the expanded feed hopper 8 are conical. The expanded feed hopper 8, the feed pipe 7, the feed cylinder 2 and the plastic extruder body 1 are connected.

[0041] By setting a sealing cover plate 14, it is easy to open and close the feed cylinder 2, which facilitates maintenance and operation. The operation is relatively simple and convenient. The expanded feed hopper 8, feed pipe 7, feed cylinder 2 and plastic extruder body 1 are connected, and the raw materials can be stably guided in sequence. It has good adaptability and is not easy to block.

[0042] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0043] Working principle: The feed cylinder 2 is provided at the top of the plastic extruder body 1, which can collect and store plastic thermoplastic raw materials. The feed cylinder 2 plays the role of storing and feeding materials.

[0044] The feed cylinder 2 is equipped with a support frame 3 inside, which can support a stepper motor 5 at the top and a stirring drive column 4 at the bottom. The stirring drive column 4 is equipped with uniformly distributed anti-clogging stirring blades 6. The stepper motor 5 drives the anti-clogging stirring blades 6, which can uniformly crush and mix the plastic raw materials that accumulate and clump in the feed cylinder 2, prevent the raw materials from accumulating, and ensure uniform and stable feeding.

[0045] The feed cylinder 2 is equipped with a feed pipe 7 and an exhaust guide pipe 9 on its side. After the raw material is put into the expanded feed hopper 8, it is guided into the feed cylinder 2 through the feed pipe 7. The overall feeding is more convenient and less likely to be blocked. When the raw material enters the feed cylinder 2 through the feed pipe 7, the exhaust guide pipe 9 on the side of the feed cylinder 2 assists in the air extraction and introduction. Small agglomerated materials are not likely to accumulate and block the feed pipe 7. The material guide is more convenient, the feeding is stable and uniform, and the device has anti-clogging stirring ability. It has the ability to break and stir small agglomerated particles, and it is not easy to block the feeding. The material is uniform and stable, and the output uniformity and quality are high.
