Description

Technical Field

[0002] Rubber is a highly elastic material with reversible deformation. Rubber can deform under the action of external force and return to its original shape when the external force is removed. It is often used in all aspects of industry and life. Rubber additives are needed in rubber production. Existing rubber additives mainly include vulcanizers, accelerators, activators and anti-scorching agents, etc. It can not only be well dispersed in the rubber material to prevent the formation of bubbles during vulcanization, but also increase the cross-linking speed and product qualification rate. Therefore, with the development of the rubber industry, rubber additives have also developed.

[0003] At present, when rubber additives are involved in rubber production, they need to be mixed with various rubber raw materials in a mixing device. During the mixing process, the heating effect of the heating mechanism is used to achieve the melting of the rubber raw materials and the rubber additives. Most existing mixing devices are equipped with a stirring mechanism, which stirs the rubber additives and the rubber raw materials through the stirring mechanism to achieve uniform mixing. However, the existing stirring mechanism has a relatively single stirring method for the rubber additives and the rubber raw materials.

During the movement of the stirring rods 302, the rubber additive raw material is preliminarily stirred to achieve uniform mixing of the rubber additive raw material and improve the melting effect of the rubber additive raw material.

[0025] See also Figure 2 、 Figure 4 as well as Figure 6In one embodiment, the second driving assembly 40 includes a support ring plate 401 and an arc-shaped protrusion 403. The support ring plate 401 is installed on the inner wall of the mixing tank 10. The arc-shaped protrusion 403 is provided with a plurality of groups. The plurality of arc-shaped protrusions 403 are fixedly arranged on the inner wall of the support ring plate 401 and are distributed in an annular manner along the inner wall of the support ring plate 401. Each group of support shafts 301 vertically penetrates the corresponding support plate 303 and rotates with the support plate 303. A group of gears 304 are fixedly provided on the upper end of each group of support shafts 301. One side of each group of support plates 303 is A group of sliding rods 305 are provided, one end of the sliding rod 305 is provided with a socket, and the other end extends toward the inner wall of the support ring plate 401, a guide rod 308 is movably inserted into the socket at one end of the sliding rod 305, and the end of the guide rod 308 away from the sliding rod 305 is fixedly connected to the side wall of the rotating shaft 202, and the sliding rod 305 and the rotating shaft 202 are also connected by a first elastic member 307, and the first elastic member 307 is used to provide elastic support for the sliding rod 305, and a rack 306 is fixedly provided on the side wall of the sliding rod 305, and the rack 306 is engaged with the gear 304.

[0026] When the motor 201 drives the rotating shaft 202 to rotate and then drives the support plate 303, the support shaft 301 and the stirring rod 302 to perform circular motion to perform preliminary stirring of the rubber additive raw material, the rotating shaft 202 can also drive the guide rod 308 and the sliding rod 305 to perform synchronous circular motion. When the sliding rod 305 moves in a circular motion, the end thereof away from the rotating shaft 202 can act on a plurality of arc-shaped protrusions 403 in sequence. When the end of the sliding rod 305 away from the rotating shaft 202 acts on a certain group of arc-shaped protrusions 403, the group of arc-shaped protrusions 403 can push the sliding rod 305 so that the sliding rod 305 moves relative to the corresponding guide rod 308, and the corresponding first elastic member 307 is compressed. When the sliding rod 305 moves, it passes through the rack 30 6 meshes with the gear 304 and drives the support shafts 301 to rotate relative to the support plate 303, thereby driving the stirring rods 302 to rotate; when the end of the slide bar 305 away from the rotating shaft 202 passes the middle position of the group of arc-shaped protrusions 403, the first elastic member 307 pushes the slide bar 305 so that the slide bar 305 moves in the opposite direction compared to the guide bar 308, thereby driving the rack 306 to move in the opposite direction, and the reverse meshing of the rack 306 and the gear 304 drives the support shaft 301 to rotate in the opposite direction compared to the support plate 303, thereby driving the stirring rods 302 to rotate in the opposite direction, and through the forward and reverse rotation of the stirring rod 302, further stirring of the rubber additive raw material is achieved.

[0027] In one embodiment, the plurality of stirring rods 302 located on the same group of support plates 303 are staggered along the length direction of the support shaft 301. When the rack 306 and the gear 304 are engaged in forward and reverse rotation to drive the plurality of stirring rods 302 to rotate forward and reverse, the plurality of stirring rods 302 outside the two adjacent groups of support shafts 301 are staggered with each other. Therefore, the rotating stirring rods 302 can produce a shearing effect on the rubber additive raw material, and the agglomerated rubber additive raw material can be broken up under the shearing effect, thereby improving the mixing effect between the rubber additive raw materials and improving the melting effect.

[0028] See also Figure 2 In one embodiment, a limiting assembly 50 is provided on the inner wall of the mixing tank 10, and the limiting assembly 50 is used to limit the support ring plate 401, and then limit the plurality of arc-shaped protrusions 403, so that the plurality of arc-shaped protrusions 403 can stably provide support for the plurality of slide bars 305, so that the slide bars 305 can stably drive the plurality of support shafts 301 and the plurality of stirring rods 302 to rotate through the rack 306 and the gear 304. The mixing tank 10 is further provided with an adjusting assembly 60, which is arranged on the circumference of the slide bar 305. After one circle of movement, the adjustment component 60 is used to adjust the position of the support ring plate 401 and the several arc-shaped protrusions 403, so that during the subsequent circular movement of the slide rod 305, the several arc-shaped protrusions 403 can provide support to the slide rod 305 at different positions inside the mixing tank 10, so that the slide rod 305 drives the support shaft 301 and the stirring rod 302 to rotate at different positions, thereby changing the rotation position of the stirring rod 302 inside the mixing tank 10, and realizing the dead-angle-free stirring of the rubber additive raw materials.

[0029] See also Figure 4In one embodiment, the support ring plate 401 is rotatably mounted on the inner wall of the mixing tank 10, and a plurality of limiting teeth 404 distributed in an annular manner are fixedly provided on the upper part of the support ring plate 401. A damping plate 405 is embedded on the inner wall of the support ring plate 401. The adjusting component 60 includes a second push rod 602, which is fixedly provided at one end of one group of the sliding rods 305 away from the rotating shaft 202. A supporting sleeve 601 is fixedly provided on the outside of the second push rod 602. The limiting component 501 includes a second elastic member 501, a slide plate 502, a limiting plate 503 and a first elastic member 501.

[0030] When the rotating shaft 202 drives the plurality of slide bars 305, the plurality of support shafts 301 and the plurality of stirring rods 302 to move in a circular motion, the lower end of the limiting piece 503 extends between two adjacent sets of limiting teeth 404 under the elastic support of the second elastic member 501, thereby limiting the rotation of the supporting ring plate 401 and the plurality of arc-shaped protrusions 403, so that the plurality of arc-shaped protrusions 403 can stably provide support for the plurality of slide bars 305, so that the plurality of support shafts 301 and the plurality of stirring rods 302 can rotate smoothly. After the rotating shaft 202 drives the plurality of slide rods 305 to move in a circle, the supporting sleeve 601 on the outside of the second push rod 602 at one end of the rotating shaft 202 acts on the lower end of the first push rod 504, thereby pushing the first push rod 504 to make the slide plate 502 slide up along the inner wall of the mixing tank 10, thereby driving the limiting plate 503 to move upward. When the limiting plate 503 moves upward, its lower end is removed from between two adjacent groups of limiting teeth 404, thereby releasing the rotation of the support ring plate 401 and the plurality of arc-shaped protrusions 403. The second push rod 602 is limited. At this time, the end of the second push rod 602 away from the sliding rod 305 acts on the damping plate 405, and the friction with the damping plate 405 drives the support ring plate 401 to rotate along the inner wall of the mixing tank 10, thereby driving the plurality of arc-shaped protrusions 403 to rotate. When the supporting sleeve 601 passes over the first push rod 504, the second elastic member 501 pushes the slide plate 502 to slide down along the inner wall of the mixing tank 10, thereby driving the limiting plate 503 and the first push rod 504 to move downward, and the lower end of the limiting plate 503 is reinserted into a certain adjacent two The group of limiting teeth 404 is used to limit the rotation of the support ring plate 401 and the plurality of arc-shaped protrusions 403 again. At this time, the plurality of arc-shaped protrusions 403 rotate to a predetermined angle, and the plurality of arc-shaped protrusions 403 can continue to provide support to the plurality of slide bars 305 in the next circular motion cycle of the plurality of slide bars 305, so that the rotation position of the plurality of support shafts 301 and the plurality of stirring rods 302 in the next circular motion cycle is changed, thereby eliminating the stirring dead angle and realizing comprehensive and sufficient stirring of the rubber additive raw materials.

While the plurality of support plates 303, the plurality of support shafts 301 and the plurality of stirring rods 302 are moving in a circular motion, the sliding rods 305 on one side of the plurality of support plates 303 can be moved in sequence. The plurality of arc-shaped protrusions 403 cooperate with the first elastic member 307 to drive the slide bar 305 to move back and forth relative to the guide bar 308, thereby driving the rack 306 to move back and forth, and utilizing the positive and negative meshing action of the rack 306 and the gear 304 to drive the plurality of support shafts 301 to rotate forward and reverse, thereby driving the plurality of stirring rods 302 to rotate forward and reverse, so as to further stir the rubber additive raw materials; when a certain group of support plates 301 moves in a circle for one circle, the slide bar 305 on one side thereof moves away from the second push rod 602 at one end of the rotating shaft 202 When the first push rod 504 is below, the supporting sleeve 601 on the second push rod 602 acts on the bottom of the first push rod 504, thereby pushing the first push rod 504 to make the slide plate 502 slide up along the inner wall of the mixing tank 10, and the slide plate 502 drives the limiting plate 503 to move upward, so that the lower end of the limiting plate 503 is removed from between two adjacent sets of limiting teeth 404, thereby releasing the rotation restriction of the support ring plate 401 and the plurality of arc-shaped protrusions 403. At this time, the second push rod 602 acts on the damping plate 405 and drives the support ring plate 401 and the plurality of arc-shaped protrusions 403 to rotate. When the supporting sleeve 601 is removed from the lower end of the second push rod 504, the second elastic member 501 pushes the slide plate 502 so that the slide plate 502 slides down along the inner wall of the mixing tank 10, thereby driving the limiting plate 503 to move downward, so that the lower end of the limiting plate 503 is reinserted between two adjacent groups of limiting teeth 404 to re-limit the rotation of the support ring plate 401 and the plurality of arc-shaped protrusions 403.
