Description

Technical Field

[0001] This utility model relates to the field of rubber tire technology, specifically a rubber extruder for rubber tire production. Background Technology

[0002] While early extruders enabled continuous rubber extrusion, they required pre-heating of the rubber compound, which easily led to high energy consumption and low efficiency. They also caused uneven plasticization, making it difficult to meet the needs of high-precision tire manufacturing. As tire size increased and performance requirements improved, traditional extruders could not meet multiple requirements such as wet skid resistance and low rolling resistance. Therefore, a rubber extruder for rubber tire production was developed.

[0003] For example, Chinese patent CN222662591U discloses a plastic extruder that is easy to feed. In this design, the extruder base, feeding hopper, drive motor and extruder body are coordinated to design the feeding hopper as a large opening and divide it into left and right parts. This not only does not affect the raw material feeding rate, but also allows multiple ingredients to be added at the same time for pre-mixing, thereby improving the practicality and efficiency of the equipment.

[0004] Based on the above-disclosed technical solutions and existing technologies, the rubber particles are of uneven size, and most equipment does not pre-crush the rubber raw materials, which easily leads to uneven mixing of raw materials and blockage during the discharge process. Therefore, we propose a rubber extruder for rubber tire production that can crush the rubber raw materials, thereby improving the rubber extrusion efficiency. It can also preheat the rubber raw materials, which is beneficial to improving the rubber extrusion efficiency and greatly improving the energy-saving performance of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] This utility model provides, for example Figure 1-5 The rubber extruder for producing rubber tires shown includes a trolley 1, a mixing tank 6, a feeding pipe 10, and a worm gear 14. The bottom of the trolley 1 is equipped with casters at equal intervals. A handle is fixedly connected to the top of one side of the trolley 1. Before operation, the trolley 1 can be pushed to move the equipment to the working position. The top of the trolley 1 is equipped with two symmetrical support seats 2. The top of the support seats 2 is equipped with a heating tube 3. A high-temperature resistance wire 31 is installed inside the heating tube 3. One end of the heating tube 3 is connected to an air outlet pipe 32. A feeding pipe 4 is installed inside the heating tube 3. The heating tube 3 adopts resistance heating. One end of the high-temperature resistance wire 31 is connected to a power source through a silver-nickel alloy special connector. The power source passes current into the high-temperature resistance wire 31 to generate heat. The high-temperature resistance wire 31 can be heated rapidly, thereby heating the feeding pipe 4. A feeding port 5 is opened on one side of the feeding pipe 4.

[0022] The top of the mixing tank 6 is connected to a feed box 22. The two ends of the rotating rods A16 and B20 are rotatably connected to the inner wall of the feed box 22. After being crushed by the feed box 22, the rubber raw material falls into the interior of the mixing tank 6. A central shaft 7 is set inside the mixing tank 6. Stirring rods 8 are connected at equal intervals on the outside of the central shaft 7. A scraper is fixedly connected to one end of the stirring rod 8. The central shaft 7 drives the stirring rods 8 and the scraper to mix the rubber raw material inside the mixing tank 6. A spiral blade 9 is sleeved on the outside of the bottom end of the central shaft 7. The spiral blade 9 conveys the rubber raw material inside the discharge pipe 10, which can prevent the rubber raw material from clogging inside the discharge pipe 10. The bottom of the mixing tank 6 is connected to the discharge pipe 10, and the spiral blade 9 is set inside the discharge pipe 10.

[0023] One end of the feeding pipe 10 is connected to the discharge pipe 4. The discharge pipe 4 is equipped with an auger 11. One end of the auger 11 is fixedly connected to a drive motor 12. After the drive motor 12 is started, the auger 11 extrudes the heated rubber material inside the discharge pipe 4 from the discharge port 5. One side of the auger 11 is connected to the central shaft 7 through a gear set 13. A protective shell 24 is provided on the outside of the gear set 13. The protective shell 24 is fixedly connected to one side inside the discharge pipe 4. One side of the protective shell 24 is an inclined surface, which facilitates better feeding of the rubber material falling from the inside of the feeding pipe 10.

[0024] A worm gear 14 is fixedly connected to the top of the central shaft 7. A worm wheel 15 is driven to one side of the worm gear 14. A rotating rod A16 is fixedly connected to the middle of the worm wheel 15. Crushing rollers A17 are connected to both ends of the rotating rod A16. A gear A18 is fixedly connected to the outer side of the rotating rod A16. A gear B19 meshes with one side of the gear A18. A rotating rod B20 is fixedly connected to the middle of the gear B19. Crushing rollers B21 are connected to both ends of the rotating rod B20. The central shaft 7 drives the worm wheel 15 to rotate via the worm gear 14. The worm wheel 15 utilizes the rotating rod A16... Rotor 16 drives gears A18 and B19 to rotate, thereby causing rotors A16 and B20 to drive crushing rollers A17 and B21 to crush the rubber raw material. A mounting shell 23 is fixedly connected to the middle of the inner side of the feed box 22. The top of the worm gear 14 is rotatably connected to the inner wall of the mounting shell 23. The worm gear 14, worm wheel 15, gears A18 and B19 are arranged inside the mounting shell 23. The mounting shell 23 can protect the worm gear 14, worm wheel 15, gears A18 and B19 and extend their service life.

[0025] The implementation principle of a rubber extruder for producing rubber tires in this application embodiment is as follows: When using the rubber extruder for producing rubber tires, firstly, push the trolley 1 to move the equipment to the working position, start the drive motor 12, pour the rubber raw material into the feed box 22, and crush the rubber raw material with crushing roller A17 and crushing roller B21 and then let it fall into the mixing tank 6.

[0026] The central shaft 7 drives the stirring rod 8 and scraper to mix the rubber raw materials inside the mixing tank 6. After mixing, the raw materials are transported to the discharge pipe 4 through the spiral blades 9 inside the discharge pipe 10. The heating pipe 3 heats the rubber raw materials inside the discharge pipe 4, and the auger 11 extrudes the raw materials from the discharge port 5.
