[0031] 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.

[0032] Reference Figure 1 and Figure 4 This utility model provides an embodiment of an extrusion device for recycled rubber, including a barrel 13. The barrel 13, as a key component in the entire device for containing and processing the mixture, is made of high-quality high-temperature resistant alloy material, capable of effectively withstanding the heat generated by the heating rod 14 during processing. This ensures that the internal mixture can be heated and melted in a suitable environment, guaranteeing the smooth operation of the entire extrusion production process. A barrel head 20 is fixedly connected to the left end of the barrel 13. The barrel head 20 is also made of a robust alloy material with certain heat resistance. It serves to connect the barrel 13 to subsequent components, allowing the processed mixture to smoothly transition to the discharge stage. Its good sealing performance prevents leakage during the transition process, thereby ensuring the stability and continuity of product extrusion. The top of the cylinder head 20 is fixedly connected to a hydraulic press support 21. The hydraulic press support 21 is made of high-strength steel and has sufficient support strength to stably support the hydraulic press 22. This ensures that the hydraulic press 22 will not shift due to its own vibration or external force during operation, and provides a reliable support foundation for the accurate movement of the subsequent drive components.

[0033] A hydraulic press 22 is fixedly connected to the left end of the hydraulic press bracket 21. The hydraulic press 22 can precisely control the magnitude and direction of the driving force. A drive plate 23 is fixedly connected to the drive end of the hydraulic press 22. The drive plate 23 is made of hard steel with good wear resistance. Driven by the hydraulic press 22, it can move smoothly and accurately in the up and down direction, thereby driving other connected components to work together. Its precise motion control plays a key guiding role in the subsequent component installation process, ensuring that each related component is accurately matched in the predetermined manner. Two sliding shafts 24 are fixedly connected to the bottom end of the drive plate 23. The sliding shafts 24 are made of stainless steel with a smooth surface and high hardness. This material characteristic allows the sliding shafts 24 to minimize friction when sliding, ensuring smooth movement, thereby efficiently completing the cooperation action with other components and realizing the fixing operation.

[0034] Two sliding shafts 24 are externally slidably connected to insert shafts 25. The design and size of the insert shafts 25 allow them to be accurately embedded inside the barrel head 20, serving as initial positioning and connection, laying the foundation for subsequent operations. A fixing sleeve 27 is slidably connected to the bottom end of each sliding shaft 24. The fixing sleeve 27 is made of robust and durable steel, and its internal structure is carefully designed with suitable insertion slots and tracks to ensure a tight fit with the sliding shaft 24. When the sliding shaft 24 slides inside, the fixing sleeve 27 provides stable support and limiting, ensuring that the sliding shaft 24 moves to the accurate position and preventing loosening or displacement during product extrusion. An outlet 26 is fixedly connected to the adjacent ends of the two insert shafts 25. The outlet 26 serves as the final extrusion outlet for the product. It is made of wear-resistant and high-temperature-resistant stainless steel, which effectively resists the erosion of the mixture and the effects of high temperatures during extrusion, ensuring the service life of the outlet 26 and the quality of the extruded product.

[0035] Reference Figures 1 to 2 The cleaning assembly includes a top plate 1, which serves as the top support structure for the entire assembly. Made of steel, its primary function is to provide a stable and reliable mounting base for the components connected below, ensuring that it will not deform or be damaged due to stress or environmental factors during operation, thus guaranteeing the normal operation of the cleaning assembly. A motor 2 is fixedly connected to the bottom of the top plate 1. Motor 2 is the core power source driving the entire cleaning assembly, stably outputting rotational power to provide a continuous energy source for subsequent stirring and cleaning operations. Its precise speed control allows related components to operate at a predetermined speed and rhythm, effectively improving the cleaning and stirring effect. A drive plate 3 is fixedly connected to the drive end of motor 2. Drive plate 3 is made of a hard yet lightweight metal alloy, capable of rapid and smooth circular motion under the drive of motor 2. Its excellent rigidity ensures that it will not bend or break during high-speed rotation, effectively driving the connected subsequent components to work together.

[0036] Two stirring columns 4 are fixedly connected to the bottom of the drive plate 3. The stirring columns 4 are made of stainless steel and are cylindrical in shape, providing excellent stirring effect during rotation. While rotating, the stirring columns 4 stir the raw materials and additives. The rapid rotation of the stirring columns 4 ensures thorough mixing of the raw materials and additives, breaking up any agglomerates and ensuring uniform distribution of various components. This is beneficial for the uniformity of chemical reactions in subsequent processing and for consistent product quality. Scrapers 5 are fixedly connected to the far ends of the two stirring columns 4. The scrapers 5 are made of rubber with a certain degree of elasticity and wear resistance. This material effectively cleans adhering additives when in contact with the inner wall of the relevant components without scratching them. As the scrapers 5 rotate, they slide inside the relevant components, cleaning the additives adhering to the inner wall. Due to their elasticity, the scrapers 5 can closely conform to the curved shape of the inner wall of the components, thoroughly scraping away the additives and preventing residues from affecting the flow and mixing effect of subsequent raw materials. This also avoids clogging of the relevant components due to the accumulation of residual additives.

[0037] A drive shaft 7 is fixedly connected to the bottom end of drive plate 3. Drive shaft 7 is made of high-strength metal and has good torsional resistance, enabling it to stably transmit the rotational power of drive plate 3. Two scrapers 8 are fixedly connected to the bottom end of drive shaft 7. Scrapers 8 are similar to scraper 5 and are made of rubber. Their shape and size are designed for cleaning. When drive shaft 7 drives the external short column to rotate and stir the raw materials and additives, it also drives scrapers 8 to rotate. Scrapers 8 clean the additives adhering to the inner wall of the relevant components. Through the stirring of drive shaft 7 and its short column, and the cleaning action of scrapers 8, the mixing degree and flow smoothness of raw materials and additives are further enhanced. Comprehensive cleaning and stirring are carried out from different angles and positions to ensure that there are no residual impurities and additives accumulated in the relevant components, creating favorable conditions for the subsequent smooth entry of the mixture into the feed cylinder 13. The bottom end of the top plate 1 is fixedly connected to a long bracket 9. The long bracket 9 is made of metal and has sufficient length and strength. Its main function is to provide auxiliary support and positioning for the entire cleaning assembly, so that the cleaning assembly can maintain a stable installation position during feeding and avoid displacement or shaking due to vibration or other external forces during operation, thereby ensuring the accuracy and reliability of cleaning and mixing work.

[0038] Reference Figures 2 to 4The feeding assembly includes a hydraulic press 10, which provides power to subsequent components. A baffle plate 11 is fixedly connected to the drive end of the hydraulic press 10. The surface of the baffle plate 11 is finely polished to ensure good sealing during sliding, effectively preventing the mixture from entering subsequent components without permission, while ensuring smooth passage of the mixture when open, avoiding leakage that could cause material loss and production interruption. A feed inlet 12 is slidably connected to the outside of the baffle plate 11. The feed inlet 12 is made of high-temperature resistant and wear-resistant stainless steel, with a smooth inner wall to reduce resistance during mixture flow, facilitating the rapid and uniform entry of raw materials and additives into the feed cylinder 13. A feed hopper 6 is fixedly connected to the top of the feed inlet 12. The feed hopper 6 is a tapered metal container with a large opening for easy loading of raw materials and additives. Its inclined inner wall helps materials slide naturally under gravity. The feeding assembly includes a motor 18, a key component providing rotational power to related components, ensuring continuous power output. The drive end of motor 2 18 is fixedly connected to a spiral roller 19, which is made of high-strength cast steel. Its external spiral blades are designed with a specific pitch and shape, which can efficiently push the mixture in the material cylinder 13 forward when rotating, ensuring the continuity and stability of material transportation.

[0039] A baffle 15 is rotatably connected to the outside of the spiral roller 19. The baffle 15, made of robust steel, is fixed inside the material cylinder 13. Its function is to limit the rotation range of the spiral roller 19, preventing it from deviating during rotation, and also helping to guide the mixture along a predetermined path, improving feeding accuracy. The baffle 15 is externally fixedly connected to the inside of the material cylinder 13. The material cylinder 13, as the core housing component of the entire device, has an internal cavity providing space for the heating, melting, and transfer of the mixture. Its good heat insulation performance reduces heat loss and improves energy utilization. Multiple heating rods 14 are fixedly connected inside the material cylinder 13. The heating rods 14 use highly thermally conductive steel as their outer shell. The internal heating elements can quickly generate heat and evenly transfer it to the mixture inside the material cylinder 13, enabling the mixture to quickly reach the required melting temperature and ensuring efficient processing. The material cylinder 13 is externally fixedly connected to multiple cylinder supports 16. The cylinder supports 16 are made of sturdy steel material, with sufficient strength and stability, which can firmly support the material cylinder 13 and keep it in a stable position during operation, avoiding tilting or displacement due to vibration or other external forces.

[0040] A base 17 is fixedly connected to the bottom of the cylinder support 16. The base 17 is made of heavy steel, increasing the contact area with the ground and providing a stable support foundation to ensure that the entire device will not shake or tip over during operation. The discharge port 26 has an opening inside, the size and shape of which are precisely designed to control the shape and flow rate of the extruded product. The external part of the discharge port 26 is slidably connected to the inside of the cylinder head 20, ensuring stability and sealing during installation and use. The cylinder head 20 has two slots inside, the shape and size of which perfectly match the insert shaft 25. The cylinder head 20 provides accurate positioning and reliable connection points for the installation of the discharge port 26. The external part of the insert shaft 25 is slidably connected to the inside of the cylinder head 20. The insert shaft 25 is made of stainless steel and serves as a preliminary positioning element during the installation of the discharge port 26. The two scrapers 5 have their far ends slidably connected to the inside of the feeding assembly. During rotation, they can closely adhere to the inner walls of the feeding hopper 6 and the feeding port 12, effectively cleaning adhering additives and ensuring smooth material flow. The two scrapers 28 have their far ends slidably connected inside the feeding assembly, which further prevents additive residue and improves the cleanliness of the feeding assembly and material transfer efficiency. The left end of the material cylinder 13 is fixedly connected to the right end of the cylinder head 20, and the connection is sealed by welding to ensure no leakage.

[0041] Working Principle: At the start of production, workers pour raw materials and additives into the feed hopper 6. Motor 2 is then activated, driving drive plate 3 to rotate. Simultaneously, drive plate 3 rotates, causing stirring column 4 and scraper 5 to rotate. Stirring column 4 agitates the raw materials and additives inside feed hopper 6. As scraper 5 rotates, the two scrapers slide inside feed hopper 6, cleaning additives adhering to the inner wall. Drive plate 3 drives drive shaft 7 to rotate, which in turn rotates the external short column to agitate the raw materials and additives. Simultaneously, it drives scraper 8 to rotate, sliding inside feed hopper 6 to clean additives adhering to the inner wall. After agitation is complete, hydraulic press 10 is activated. Hydraulic press 10 drives baffle plate 11 to slide forward inside feed inlet 12, allowing the agitated mixture of raw materials and additives inside feed hopper 6 to enter the material cylinder 13 through feed inlet 12.

[0042] When the mixture enters the inside of the barrel 13, the second motor 18 is started. The second motor 18 drives the spiral roller 19 to rotate inside the baffle 15. Under the action of the spiral blades outside the spiral roller 19, the mixture is transported. The mixture inside the barrel 13 is heated and melted by the heating rod 14 inside the barrel 13. Then, the spiral roller 19 transports the melted mixture to the inside of the barrel head 20 and the discharge port 26. The product is extruded through the discharge port 26.

[0043] When installing the discharge port 26, the discharge port 26 is inserted into the opening inside the cylinder head 20. The discharge port 26 drives the insertion shaft 25 to be inserted into the slot inside the cylinder head 20. When the insertion shaft 25 and the discharge port 26 are inserted into the appropriate position, the hydraulic press 22 is started. The hydraulic press 22 drives the drive plate 23 to move downward. The drive plate 23 drives the sliding shaft 24 to move downward. The sliding shaft 24 slides downward inside the insertion shaft 25 and the fixing sleeve 27 at the same time. When the bottom end of the sliding shaft 24 moves to the bottom end of the insertion port inside the fixing sleeve 27, the discharge port 26 is fixed.
