Description

Technical Field

[0001] The invention relates to the technical field of stirring equipment, in particular to a stirring transmission structure and a disperser. Background Art

[0002] A stirring and dispersing machine is a mixing device commonly used in the fields of chemical, pharmaceutical, and food, which can achieve efficient mixing and dispersion of materials. Existing stirring and dispersing machines usually adopt a multi-stage variable speed transmission structure to improve the mixing effect of materials through a combination of high-speed dispersion and low-speed stirring.

[0003] For example, patent CN202020021914.7 discloses a mixer with a multi-speed transmission structure, in which the transmission mechanism includes a high-speed dispersion transmission component and a low-speed stirring transmission component, and multi-speed transmission is achieved through a pulley and a gear assembly. The pulley assembly is used to drive the dispersion mechanism to rotate at high speed, and the bevel gear increases the stirring force, thereby achieving dispersion and mixing of different materials.

[0004] However, although this structure can achieve multi-stage transmission, it binds the rotation of the stirring main shaft to the revolution of the entire equipment. There is a fixed speed ratio relationship between the revolution and stirring, and the two cannot be adjusted independently. This structure will lead to insufficient flexibility of the equipment under certain complex working conditions, and it cannot adapt to the diverse needs of different materials and operating conditions, especially in situations where precise control of stirring, dispersion and overall revolution speed is required. In addition, due to the binding relationship between stirring and revolution, each motion layer cannot be independently controlled, which increases the difficulty of operation and reduces efficiency of the equipment when handling different working conditions. The mutual interference between the various functional layers will also affect the mixing uniformity of the material, thereby affecting the dispersion quality. Summary of the invention

[0005] To this end, the present invention provides a stirring transmission structure and a disperser, which can realize independent adjustment of the rotation speeds of the stirring main shaft, the dispersion main shaft and the revolution main body, thereby improving the dispersion quality.

[0026] Through the above-mentioned arrangement, it can be achieved that the rotation speeds of the first spindle 1, the second spindle 2 and the second spindle 2 do not affect each other and can be adjusted independently, that is, the rotation speeds of the stirring spindle 10, the dispersing spindle 11 and the revolving body 4 can be adjusted separately, which not only improves the control accuracy of the equipment, but also can adjust the rotation speed of each layer according to different working conditions and material characteristics, thereby maximizing the mixing and dispersing efficiency, and avoiding the problem of uneven mixing caused by mutual interference between moving layers in traditional equipment.
