Description

Technical Field

[0001] This utility model relates to the field of heated extrusion molding technology, specifically a heated extrusion molding device for automotive rubber composite materials. Background Technology

[0002] In the modern automotive industry, rubber composite materials are widely used in various automotive components, such as tires, seals, and shock absorbers. The performance of these rubber components directly affects the safety, comfort, and overall performance of the vehicle. With the continuous development of the automotive industry, the quality and performance requirements for automotive rubber composite materials are increasingly stringent. For example, tires need excellent wear resistance, grip, and anti-aging properties to ensure driving safety under various road conditions; seals must have good sealing performance and weather resistance to prevent liquid or gas leakage and ensure the normal operation of critical components such as the engine and transmission; automotive rubber hoses play a crucial role in transporting various fluids in the automotive system, such as fuel, coolant, and brake fluid, and their performance directly affects the vehicle's operational safety and stability.

[0003] For example, Chinese utility model patent application number 202020016435.6 discloses an extrusion device for rubber processing. Rubber ingredients are added to a mixing tank and thoroughly mixed. The rubber then enters the feeding tank through the inlet. Under the action of a pressure plate and a bottom plate, the rubber ingredients are extruded. A hydraulic rod pushes the extrusion plate downwards, compacting the rubber ingredients. The pressure plate and bottom plate return to their initial state, and the extrusion plate pushes the compacted rubber ingredients into the extrusion cylinder. A heating cylinder inside the extrusion cylinder keeps the ingredients constantly heated and moisturized, ensuring the performance of the extrusion molding. The cooperation between the forming cylinder and the cooling pipe effectively reduces adhesion and ensures the consistency of product quality. However, this device still has certain shortcomings.

[0004] When the heated extrusion molding device is feeding materials, it cannot filter out fine dust and impurities in the rubber raw materials, resulting in a large amount of dust and impurities being mixed into the rubber raw materials. These dust and impurities are incorporated into the rubber materials, affecting the production quality of automotive rubber products.

[0005] Therefore, we propose a heated extrusion molding device for automotive rubber composite materials to solve the problems mentioned above. Utility Model Content

[0032] 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.

[0033] Please see Figures 1-5This utility model provides a technical solution: a heating extrusion molding device for automotive rubber composite materials, comprising a support frame 1, a heating molding device 2, a cooling pipe 3, an extrusion pipe 4, a mounting frame 5, a first servo motor 6, a spiral conveyor rod 7, a feed inlet 8, a crushing frame 9, a drive shaft 10, a blade assembly 11, a connecting belt 12, a connecting plate 13, a vertical plate 14, a second servo motor 15, a rotating disk 16, a first hinge assembly 17, a collection box 18, a guide rod 19, a baffle 20, a screen assembly 21, a guide strip 22, a guide groove 23, a second hinge assembly 24, and a pusher strip 25. The heating molding device 2 is mounted above the support frame 1, and a heating mechanism is provided inside the heating molding device 2. A cooling pipe 3 is mounted on the right side of the heating molding device 2. Furthermore, an extrusion pipe 4 is installed on the right side of the cooling pipe 3. The crushed raw material falls into the heating and molding device 2 through the feed port 8. The heating mechanism heats the raw material to soften it, and then it is extruded and molded through the extrusion pipe 4. The cooling pipe 3 cools and shapes the molded rubber composite material. The feed port 8 is opened above the heating and molding device 2. The feed port 8 is located directly below the crushing frame 9. The automotive rubber raw material on the screen assembly 21 is conveyed to the crushing frame 9. The crushed raw material falls into the heating and molding device 2 through the feed port 8. A mounting frame 5 is installed on the left side of the heating and molding device 2. The crushing frame 9 is installed above the heating and molding device 2. A first servo motor 6 is installed on the left side of the mounting frame 5, and a spiral conveyor rod 7 is installed on the right side of the first servo motor 6 through the output shaft.

[0034] Inside the crushing frame 9, a drive shaft 10 is installed via a bearing housing, and a blade assembly 11 is mounted on the drive shaft 10. The drive shaft 10 is connected to the screw conveyor 7 via a connecting belt 12. Both the drive shaft 10 and the screw conveyor 7 are equipped with pulleys. When the first servo motor 6 is started, its output shaft drives the screw conveyor 7 to rotate, and at the same time, the drive shaft 10 is driven to rotate via the connecting belt 12, so that the blade assembly 11 crushes the rubber raw material in the crushing frame 9.

[0035] A connecting plate 13 is installed above the heating forming device 2, and a vertical plate 14 is installed above the connecting plate 13. A second servo motor 15 is installed on the rear side of the vertical plate 14, and a rotating disk 16 is installed on the front surface of the second servo motor 15 through the output shaft. A first hinge assembly 17 is installed on the rotating disk 16. The first hinge assembly 17 is located at a non-center position of the rotating disk 16. During the raw material conveying process, the second servo motor 15 drives the rotating disk 16 to rotate. Since the first hinge assembly 17 is located at a non-center position of the rotating disk 16, the rotating disk 16 drives the baffle 20 to slide back and forth on the guide rod 19 through the push bar 25 and the second hinge assembly 24. The inclined screen assembly 21 screens out dust and impurities in the raw material, which fall into the collection box 18. The raw material that meets the requirements enters the crushing frame 9 through the screen. The collection box 18 is installed between the crushing frame 9 and the connecting plate 13. A guide rod 19 is installed on the left side of the connecting plate 13, and a baffle 20 is installed on the guide rod 19. A screen assembly 21 is installed on the left side of the collection box 18. The screen assembly 21 has an inclined structure design and is located above the collection box 18. The diameter of the filter holes in the screen assembly 21 is smaller than the diameter of the automotive rubber material. The baffle 20 is slidably connected to the guide rod 19. The guide rod 19 guides the left and right movement of the baffle 20, making the left and right movement of the baffle 20 more stable, and thus making the left and right movement of the screen assembly 21 more stable. A second hinge assembly 24 is installed on the right side of the baffle 20, and the second hinge assembly 24 is connected to the first hinge assembly 17 through a push bar 25. Protective plates are provided on both the front and rear sides of the screen assembly 21, and guide bars 22 are installed on both the front and rear sides of the screen assembly 21. A guide groove 23 is opened on the upper surface of the collection box 18. The guide bars 22 are slidably connected to the guide groove 23. The protective plates on the front and rear sides of the screen assembly 21 prevent the automotive rubber material from overflowing, and the sliding connection between the guide bars 22 and the guide groove 23 ensures that the screen assembly 21 moves smoothly.

[0036] Working principle: When using the automotive rubber composite material heating extrusion molding device, firstly, when processing granular automotive rubber raw materials, the raw materials are fed onto the screen assembly 21. During the raw material conveying process, the second servo motor 15 drives the rotating disk 16 to rotate. Since the first hinge assembly 17 is located at the non-center position of the rotating disk 16, the rotating disk 16 drives the baffle 20 to slide back and forth on the guide rod 19 through the push bar 25 and the second hinge assembly 24. The inclined screen assembly 21 screens out dust and impurities in the raw materials, which fall into the collection box 18, while the raw materials that meet the requirements enter the crushing frame 9 through the screen.

[0037] The first servo motor 6 is started, and its output shaft drives the screw conveyor 7 to rotate. Simultaneously, the connecting belt 12 drives the transmission shaft 10 to rotate, causing the blade assembly 11 to crush the rubber raw material in the crushing frame 9. This improves the softening efficiency of the rubber raw material in the thermoforming device 2. The crushed raw material falls into the thermoforming device 2 through the feed inlet 8, and is then conveyed by the screw conveyor 7. The heating mechanism heats the raw material to soften it, and it is extruded through the extrusion tube 4. The cooling tube 3 cools and sets the molded rubber composite material, thus completing a series of processes. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0038] 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.
