[0002] Composite modified natural rubber is a high-performance material that is modified through advanced technology. It combines multiple modification methods to further enhance the physical properties and chemical stability of natural rubber while retaining its advantages such as good elasticity, wear resistance and tear resistance. In the manufacturing process of composite modified natural rubber, sufficient mixing of raw materials is a crucial step.

[0003] In the prior art, during the production and stirring process of composite modified natural rubber, due to the high viscosity of the rubber, the unloading of the rubber after stirring in the stirring device is very slow, which will extend the production cycle and reduce the overall production speed. At the same time, the slow unloading may cause the operating time of the equipment to be extended, increase energy consumption, and increase production costs. For this reason, a raw material stirring device for the manufacture of composite modified natural rubber is designed. Utility Model Content

The setting of the limiting mechanism makes it possible that when the rotating rod 4 rotates clockwise, the rotating rod 5 will not rotate, and when it rotates counterclockwise, the rotating rod 5 can rotate accordingly. One end of the outer wall of the mixing box 1 is fixedly connected to the first motor 101, and the output end of the first motor 101 passes through the mixing box 1 and is fixedly connected to one end of the rotating rod 4.

[0023] In this embodiment, circular rings 6 are rotatably connected at both ends of the interior of the mixing box 1, and the two circular rings 6 are coaxial with the rotating rod 4. A plurality of beveled tooth blocks 601 are fixedly connected to the inner walls of the circumferences of the two circular rings 6, and the beveled tooth blocks 601 are adapted to the beveled clamping blocks 704. A baffle 602 is fixedly connected to the side where the two circular rings 6 are close to each other, and a circular hole adapted to the rotating rod 4 is opened in the middle of the two baffles 602.

[0024] In this embodiment, one end of the outer wall of the two circular rings 6 is fixedly connected to a rotating rod 5, and the other ends of the two rotating rods 5 are fixedly connected to the same scraper 501, and the scraper 501 is adapted to the bottom of the mixing box 1. The bottom of the mixing box 1 is set to an arc shape to facilitate the scraping of the scraper 501, thereby realizing rapid unloading of the rubber.

[0025] In this embodiment, the rotating rod 4 is located on the circumferential surface inside the mixing box 1 and is fixedly connected to multiple groups of stirring rods 401 at equal intervals. The other end of each stirring rod 401 is fixedly connected to a stirring blade 402.

[0026] In this embodiment, a protective layer 2 is fixedly connected to the outer wall of the mixing box 1 near the bottom, a plurality of heating wires 201 are fixedly connected between the two ends of the protective layer 2, and an arc-shaped rack 202 is fixedly connected to the middle of the bottom of the protective layer 2. The setting of the heating wire 201 allows the rubber inside the mixing box 1 to be heated, thereby facilitating the mixing of the rubber.

[0027] In this embodiment, both ends of the outer wall of the mixing box 1 are rotatably connected to support frames 3, and the same round rod 302 is rotatably connected between the middle parts of the two support frames 3, and a gear 303 is fixedly sleeved on the middle part of the round rod 302, and the gear 303 is meshed with the arc-shaped rack 202. A second motor 301 is fixedly connected to the outer end of one of the support frames 3, and the output end of the second motor 301 passes through the side support frame 3 and is fixedly connected to one end of the round rod 302.

[0028] Working principle: When the device is in use, after the rubber is added to the mixing box 1, the electric heating wire 201 and the first motor 101 are started. The heating of the electric heating wire 201 makes the rubber easier to stir. The first motor 101 drives the rotating rod 4 to rotate clockwise, so that the multiple stirring rods 401 and stirring blades 402 can fully stir the rubber, which is convenient for mixing the raw materials. At this time, due to the inclined surface of the oblique tooth block 601 and the oblique clamping block 704, the rotating rod 5 will not rotate with the rotating rod 4. When the stirring is completed, the second The motor 301 causes the gear 303 to rotate, and through the meshing of the gear 303 and the arc-shaped rack 202, the mixing box 1 gradually tilts, which is convenient for the unloading of the rubber. At the same time, the first motor 101 is started to reverse. At this time, when the oblique clamping block 704 and the oblique tooth block 601 contact each other, the oblique clamping block 704 will not shrink under the action of the spring 703, so that when the rotating rod 4 rotates, the rotating rod 5 and the scraper 501 are driven to rotate, so that the scraper 501 scrapes the bottom of the mixing box 1, which is convenient for the unloading of the rubber.
