However, traditional kneading and mixing equipment often has problems such as uneven mixing, heat accumulation, and low stirring efficiency. These problems are particularly prominent when dealing with high-viscosity materials. Therefore, how to improve the mixing uniformity, heat dissipation performance, and stirring efficiency of kneading and mixing equipment has become a technical problem that needs to be solved urgently.

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] A kneading and mixing device for uniformly mixing materials, comprising a cylinder 1, a stirring paddle 2 and a motor 3, wherein the stirring paddle 2 is provided with a plurality of stirring paddles, and the stirring paddles 2 are all connected to the motor 3 through a transmission mechanism;

[0020] A heat-conducting block 4 is provided in the middle of the stirring paddle 2, and the heat-conducting block 4 is fixed on the stirring paddle 2 by bolts; the heat-conducting block 4 is connected to a heat dissipation tower 6 through a heat-conducting strip 5, and the heat-conducting strip 5 is provided inside the stirring paddle 2. The heat dissipation tower 6 is provided on the rotating shaft of the stirring paddle 2 and is located on the outside of the cylinder body 1, and can be ventilated and dissipated according to the rotation of the stirring paddle 2.

[0021] The transmission mechanism includes a driving belt transmission mechanism 7, a control belt transmission mechanism 8 and a reducer 9. The motor 3 is connected to the reducer 9 through the driving belt transmission mechanism 7, and the reducer 9 is connected to the stirring paddle 2 through the control belt transmission mechanism 8. The stirring paddle 2 is provided with two, which are respectively connected to the two transmission wheels of the control belt transmission mechanism 8, and the two transmission wheels of the control belt transmission mechanism 8 are of different sizes. The stirring paddle 2 is cast, and at this time, only the heat conductive strip needs to be placed in the mold, and the stirring paddle 2 is made by a casting process, and a wear-resistant coating is provided on its surface. The thermal conductivity of the heat conductive block 4 is better than that of the stirring paddle 2.

[0022] The working principle of the device is as follows: first, the motor 3 is started, and the motor 3 drives the reducer 9 to rotate through the driving belt transmission mechanism 7. The reducer 9 drives the stirring paddle 2 to rotate in the cylinder body 1 through the control belt transmission mechanism 8. Since the two driving wheels of the control belt transmission mechanism 8 are of different sizes, the two stirring paddles 2 will rotate at different speeds, thereby achieving differential stirring and improving the mixing uniformity of the materials.

[0023] During the stirring process, friction heat is generated between the materials and between the materials and the stirring paddle 2 and the cylinder 1. In order to conduct this heat away in time and prevent heat accumulation from affecting the mixing effect and the life of the equipment, a heat conduction block 4 is provided in the middle of the stirring paddle 2. The heat conduction block 4 has a better thermal conductivity than the stirring paddle 2 and can quickly absorb the heat on the stirring paddle 2 and transfer it to the heat conduction strip 5.

[0024] The heat conducting strip 5 is arranged inside the stirring paddle 2 and is closely connected to the heat conducting block 4. The heat conducting strip 5 further transfers the heat on the heat conducting block 4 to the heat dissipation tower 6. The heat dissipation tower 6 is located on the rotating shaft of the stirring paddle 2 and protrudes from the outside of the cylinder body 1. The purpose is to utilize the airflow generated when the stirring paddle 2 rotates to ventilate and dissipate the heat of the heat dissipation tower 6, thereby effectively dissipating the heat inside the device.

[0025] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. Based on the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
