Description

Technical Field

[0001] The utility model relates to the technical field of brake belt production, in particular to an internal mixer for rubber production. Background Art

[0002] Internal mixers are commonly used in rubber processing. They can mix and heat raw rubber with various additives to make the required rubber mixture, including rubber mixtures used to make brake bands. Internal mixers are usually composed of large steel containers and stirring devices. They can work under high temperature and high pressure to mix raw rubber and additives evenly and process them at a certain temperature to achieve the required physical and chemical properties, ensuring that the final rubber mixture meets the requirements of brake bands.

[0003] Traditional internal mixers for rubber production usually consist of two or more rotating mixing shafts, on which stirring blades are installed, which rotate and stir in a row in the inner cavity of the internal mixer and are driven by a motor.

[0004] Traditional internal mixers used in rubber production have the following problems: Since traditional internal mixers can only rotate in one direction, the rubber raw materials and additives may not be mixed evenly, and the contact area with the rubber raw materials may not be increased during the stirring process. Some raw materials may not be fully mixed, which may affect the performance and quality of the final brake belt. For this reason, we propose an internal mixer for rubber production.

At this time, the position of the teeth of the quarter gear at the rear end is mirror-symmetrical with the teeth of the quarter gear at the front end, so that the quarter gear at the rear end remains stationary. With the rotation of the large-diameter gear, the quarter gear will alternately mesh between the adjacent tooth grooves, so that the fixed plate and the slider alternately move left or right along the guide groove, and the frame and roller on the fixed shaft supported by the bearing will also move left and right accordingly through the alternating movement of the slider, thereby realizing the left-right reciprocating action, which can effectively increase the contact area between the raw rubber and various additives, thereby promoting their mixing and helping to improve the quality of subsequent brake belt production.

The gear 2 113 is fixedly sleeved on the upper end of the fixed shaft 310. The two adjacent gears 2 113 are meshed. However, when the frame 312 moves, the gear 1 111 on the fixed shaft 310 at the rear end is driven to mesh and rotate with the rack plate 112, so that the gear 1 111 starts to rotate. The rotation of the gear 1 111 drives the fixed shaft 310 at the rear end to rotate, and the rotation of the fixed shaft 310 at the rear end drives the gear The wheel 2 113 rotates, and the two adjacent gears 2 113 are meshed and connected, so that all the fixed shafts 310 start to rotate, thereby driving the rollers 313 to rotate, so that the rollers 313 can rotate when moving back and forth, thereby increasing the contact area between the rollers 313 and the raw rubber and various additives, thereby improving the mixing efficiency. The stirring mechanism 3 also includes tooth grooves 303, a fixed plate 304, a rotating shaft 307 and a quarter gear 309.

At the same time, the single chip microcomputer 7 controls the operation of the motor 301. The rotation of the output shaft of the motor 301 drives the rotating shaft 306 to rotate. The rotating shaft 306 drives the small diameter gear 305 to rotate. The small diameter gear 305 is meshed with the large diameter gears 308 at the front and rear ends, so that the large diameter gear 308 starts to rotate. The large diameter gears 308 are transmitted by the small diameter gear 305 so that they rotate in relative directions. The rotation of the large diameter gear 308 drives the rotating shaft 307 to rotate. The rotating shaft 307 drives the quarter gear 309 at its lower end to rotate. When the quarter gear 309 at the front end rotates and meshes with the adjacent tooth groove 303, this will cause the fixed plate 304 and the slider 311 to move to the right along the guide slot 302. At this time, the teeth of the rear quarter gear 309 are mirror-symmetrical to those of the front quarter gear 309, so that the rear quarter gear 309 remains stationary. As the large-diameter gear 308 rotates, the quarter gear 309 will alternately mesh between adjacent tooth grooves 303, so that the fixed plate 304 and the slider 311 alternately move left or right along the guide groove 302, and the frame 312 and the roller 313 on the fixed shaft 310 supported by the bearing will also move left and right accordingly through the alternating movement of the slider 311, thereby realizing a left-right reciprocating motion, which can effectively complete the mixing and stirring of the raw rubber and additives, making the stirring effect more uniform and improving the quality of the subsequent production of the brake belt;

[0030] The installation groove 10 is provided at the bottom of the mixing furnace 2. The installation groove 10 is provided with an electric heating wire 9.

[0032] The working principle of the internal mixer for rubber production provided by the utility model is as follows: before starting the mixing process, it is necessary to first open the sealing door 1 of the mixing furnace 2, pour the raw rubber and various additives into the mixing furnace 2 through the feed port in turn, and then use the single-chip microcomputer 7 to control the operation of the electric heating wire 9 to provide heating energy to heat the raw rubber and various additives. While heating, the internal temperature of the mixing furnace 2 is detected in real time by the temperature sensor 6 to keep the temperature inside the mixing furnace 2 within a safe range. However, in order to ensure that the gas inside the mixing furnace 2 can be discharged smoothly during the heating process, exhaust is achieved through the air valve 5 at the right end of the exhaust pipe 4 to ensure smooth exhaust. At the same time, the single-chip microcomputer 7 controls the operation of the electric heating wire 9 to provide heating energy to heat the raw rubber and various additives. The motor 301 is regulated by the machine 7. The output shaft of the motor 301 rotates to drive the rotating shaft 306 to rotate. The rotating shaft 306 drives the small diameter gear 305 to rotate. The small diameter gear 305 meshes with the large diameter gears 308 at the front and rear ends, so that the large diameter gear 308 starts to rotate. The large diameter gears 308 rotate in relative directions through the transmission of the small diameter gear 305. The rotation of the large diameter gear 308 drives the rotating shaft 307 to rotate. The rotating shaft 307 drives the quarter gear 309 at its lower end to rotate. When the quarter gear 309 at the front end rotates and meshes with the adjacent tooth groove 303, this will cause the fixed plate 304 and the slider 311 to move to the right along the guide slot 302. At this time, the rear end The teeth of the quarter gear 309 at the rear end are mirror-symmetrical with the teeth of the quarter gear 309 at the front end, so that the quarter gear 309 at the rear end remains stationary. As the large-diameter gear 308 rotates, the quarter gear 309 will alternately mesh between adjacent tooth grooves 303, so that the fixed plate 304 and the slider 311 alternately move left or right along the guide groove 302, and the frame 312 and the roller 313 on the fixed shaft 310 supported by the bearing will also move left and right accordingly through the alternating movement of the slider 311, thereby realizing a left-right reciprocating motion, which can effectively complete the mixing and stirring of the raw rubber and additives, making the stirring effect more uniform. , and improve the quality of subsequent brake belt production, however, when the frame 312 is moving, it drives the gear 111 on the fixed shaft 310 at the rear end to mesh and rotate with the rack plate 112, so that the gear 111 starts to rotate, and the rotation of the gear 111 drives the fixed shaft 310 at the rear end to rotate, and the rotation of the fixed shaft 310 at the rear end drives the gear 2 113 to rotate, and through the meshing connection of the two adjacent gear 2s 113, all the fixed shafts 310 start to rotate, and then drive the roller 313 to rotate, so that the roller 313 can rotate when moving back and forth left and right, thereby increasing the contact area between the roller 313 and the raw rubber and various additives, thereby improving the mixing efficiency.
