[0022] refer to Figure 1-Figure 3 As shown, the stirring member includes a top cover 11, a main motor 5 is provided at the center of the top surface of the top cover 11, a mixer is provided on the output shaft of the main motor 5 and penetrates the top cover 11 and is located in the stirring barrel 2, the main motor 5 drives the mixer to rotate horizontally in the stirring barrel 2, an auxiliary motor 6 is provided at the edge of the top surface of the top cover 11, one end of the feed pipe 3 penetrates the top cover 11 and is located in the stirring barrel 2, the top cover 11 is movably connected with the chassis 1, the main motor 5 is the power source of the entire stirring device, and is installed at the center of the top cover 11. When the main motor 5 is started, the rotor inside it will rotate according to the preset The main motor 5 rotates in the mixing barrel 2 at a high speed, thereby driving the mixer connected thereto. The mixer is designed to be able to adapt to lateral rotation. In this way, driven by the main motor 5, the mixer can perform all-round and multi-angle rotation stirring in the mixing barrel 2 to achieve full mixing and dispersion of the materials in the barrel. The feed pipe 3 is arranged on the top surface of the top cover 11 and is close to the main motor 5, which is convenient for continuously or intermittently adding materials to the mixing barrel 2 during the stirring process, ensuring that the materials can quickly enter the stirring area, effectively avoiding the situation where the materials are accumulated in a corner of the mixing barrel 2 and cannot be fully mixed.

[0023] refer to Figure 1 , Figure 2 as well as Figure 4As shown, the rotary drive member includes an auxiliary motor 6, the output shaft of the auxiliary motor 6 is located in the mixing barrel 2 and a gear 9 is provided at the end thereof, the gear 9 is meshed and connected with the internal gear 8, and the auxiliary motor 6 drives the mixing barrel 2 through the meshing transmission of the gear 9 and the internal gear 8. When the auxiliary motor 6 is started, the gear 9 on the output shaft starts to rotate. Since the gear 9 is meshed with the internal gear 8 on the inner wall of the mixing barrel 2, the rotational motion of the gear 9 will be effectively transmitted to the internal gear 8, thereby driving the entire mixing barrel 2 to rotate. This design can realize two different stirring actions: one is that the mixer driven by the main motor 5 performs horizontal stirring in the barrel, and the other is that the auxiliary motor 6 transmits the gear 9 to make the mixing barrel 2 itself rotate and stir. The advantage of this dual-power system is that it can mix the materials in the barrel more comprehensively and deeply.

[0024] refer to Figure 3 As shown, the mixer includes a main shaft and a stirring blade 7. The main shaft is arranged on the output shaft of the main motor 5, and the stirring blade 7 is fixedly installed on the main shaft.

A fixedly installed pulley 12 is provided near the top of the chassis 1, and multiple pulleys 12 are respectively attached to the outer side of the mixing barrel.

[0026] The working principle provided by the utility model is as follows:

[0027] When using this rubber mixer, first add the rubber raw materials to be mixed into the mixing barrel 2 through the feed pipe 3. Since the feed pipe 3 is arranged on the top of the stirring piece and close to the main motor 5, the raw materials can be added continuously and stably during the mixing process. After the main motor 5 is started, the mixer on its output shaft begins to rotate horizontally in the mixing barrel 2, and the rubber raw materials in the barrel are mixed by the stirring blades 7 to ensure that each component can be evenly dispersed. At the same time, the auxiliary motor 6 runs, and the gear 9 on its output shaft meshes with the internal gear 8 on the top of the mixing barrel 2. The mixing barrel 2 is driven to rotate as a whole through the transmission mechanism. The lateral rotation of the mixer is combined with the rotation of the mixing barrel 2 to form a composite motion. , effectively improving the mixing efficiency and mixing quality. The spiral feeding blade 10 plays the role of conveying materials in the mixing barrel 2, so that the rubber raw materials in the barrel can be continuously updated and fully mixed during the mixing process. When the mixing is completed, the valve of the discharge pipe 4 is opened, and the rubber mixture will be discharged from the discharge pipe 4 at the bottom under the rotation of the mixing barrel 2 and the action of gravity. The discharge pipe 4 is connected to the chassis 1 through a bearing, which can ensure that the mixing barrel 2 rotates smoothly and without obstruction. The pulley 12 located near the top of the chassis 1 is attached to the outer side of the mixing barrel 2. These pulleys 12 may play a supporting or guiding role, helping to maintain the stability of the mixing barrel 2 during rotation and reduce friction loss.
