[0017] As Figure 1-5 shown, a material premixing device for rubber product processing provided by the present invention includes: a base 1, a mixing barrel 2, a gantry 3, and a multi-directional stirring mechanism 4; A gantry 3 is vertically and fixedly arranged at the upper end of the base 1, and an open-up mixing barrel 2 is vertically and fixedly arranged at the upper end of the base 1 located inside it. A multi-directional stirring mechanism 4 capable of stirring the materials inside the mixing barrel 2 in multiple directions is arranged inside the gantry 3. The multi-directional stirring mechanism 4 includes: a power seat 401, stirring plates 404, and stirring blades 405; among them, The power seat 401 is vertically and rotatably arranged inside the gantry 3. Two stirring plates 404 that can be lifted and lowered vertically inside the mixing barrel 2 are vertically arranged at intervals below the power seat 401. Along the height direction of each stirring plate 404 facing the inner wall of the mixing barrel 2, a plurality of stirring blades 405 are evenly and horizontally fixedly arranged.

[0018] In the above solution, during use, the power seat 401 is started to rotate, so as to drive the two stirring plates 404 to rotate together inside the mixing barrel 2, and all the stirring blades 405 on them are used to stir the materials inside it in the horizontal direction. And the two stirring plates 404 can also be lifted and lowered vertically, so as to drive all the stirring blades 405 on them to stir the materials inside the mixing barrel 2 in the longitudinal direction. Therefore, through the multi-directional stirring mechanism 4, the materials inside the mixing barrel 2 can be stirred in multiple directions at the same time, improving the stirring effect and stirring efficiency.

[0019] In a preferred embodiment of the present invention, the multi-directional stirring mechanism 4 further includes: a power gear 402 and a power rack 403; among them, A plurality of power gears 402 are horizontally rotatably arranged at equal intervals along the height direction inside the power seat 401 located between the two stirring plates 404. Inside the power seat 401 on both sides of all the power gears 402, power racks 403 that can be lifted and lowered vertically are respectively arranged. The power racks 403 can penetrate out from the bottom of the power seat 401 and are meshed with all the power gears 402. The tops of the two stirring plates 404 are respectively fixed on the two power racks 403.

[0020] In the above solution, during use, by driving any one of the power gears 402 to rotate, two power toothed plates 403 are driven to drive two stirring plates 404 on each of them to alternately lift and lower in the vertical direction, and all the remaining power gears 402 play a role in supporting and guiding the two power toothed plates 403, improving the stability and reliability of the entire structure.

[0021] In a preferred embodiment of the present invention, the end of the central rotating shaft of any one of the power gears 402 extends out from the inside of the power seat 401 and is coaxially connected to a power motor horizontally fixed on the outer wall of the power seat 401 through a coupling.

[0022] In the above solution, the power motor is used to drive the power gear 402 coaxially connected thereto to rotate, thereby driving the two power toothed plates 403 to alternately lift and lower, and further driving the two stirring plates 404 to alternately lift and lower accordingly.

[0023] In a preferred embodiment of the present invention, the inner walls of the power seat 401 facing the two power toothed plates 403 are respectively partially recessed inward to form guiding grooves, and a guiding rod 6 is vertically and fixedly arranged in each guiding groove. A guiding slider 7 that slides vertically on the guiding rod 6 is horizontally and fixedly arranged at the upper end of each power toothed plate 403.

[0024] In the above solution, a guiding hole for the guiding rod 6 to pass through is vertically formed in the guiding slider 7, and the guiding slider 7 is slidably assembled on the guiding rod 6.

[0025] Through the cooperation of the guiding rod 6 and the guiding slider 7, on the one hand, the two power toothed plates 403 are assembled, improving their stability and reliability. On the other hand, it plays a guiding role to ensure that the power toothed plates 403 can lift and lower linearly in the vertical direction.

[0026] In a preferred embodiment of the present invention, a rotating shaft is vertically and rotatably arranged at the top of the gantry 3. The top end of the rotating shaft is coaxially connected to a driving motor 5 vertically fixed on the gantry 3 through a coupling, and the bottom end of the rotating shaft is fixed at the central position of the top of the power seat 401.

[0027] In the above solution, during use, the driving motor 5 is used to drive the rotating shaft and the power seat 401 to rotate together, providing power for the power seat 401 for its rotation.

[0028] In a preferred embodiment of the present invention, a plurality of inverted L-shaped support legs 9 are fixedly arranged at equal intervals and vertically along the circumferential direction of the rotation axis at the top of the 501, and a chute 8 for cooperating with all the support legs 9 is provided at the top of the gantry 3. The top of each support leg 9 partially extends into the chute 8, and a ball 10 capable of supporting on the chute 8 is rotatably arranged at the top of each support leg 9 extending into the chute 8.

[0029] In the above solution, under the action of all the support legs 9, the power seat 401 can be supported, improving the stability and reliability of its structure. And the ball 10 capable of abutting against the chute 8 is rotatably arranged at the top of the support leg 9, so that when the power seat 401 rotates, all the support legs 9 rotate together. During the rotation process, the sliding friction between the top of the support leg 9 and the chute 8 is converted into rolling friction through the ball 10, reducing the friction force between the two, thereby extending the service life.

[0030] In summary, the material premixing device for rubber product processing provided by the present invention overcomes the problem in the prior art that only the rotation of the stirring shaft drives a plurality of stirring blades thereon to rotate together to stir the material. Adopting this stirring method results in insufficient stirring, which affects the stirring effect and efficiency.
