Figure 1 As shown in the structure of the existing planetary low-speed mixer, the transmission shaft is connected with the planetary box, the stirring shaft is installed on the planetary box through the bearing, the fixed gear is installed on the transmission shaft above the planetary box, the planetary gear is installed on the top end of the stirring shaft, the planetary gear is engaged with the fixed gear, and the working principle is that the solid transmission shaft drives the planetary box to revolve, and then the planetary gear revolves around the fixed gear when the planetary box revolves, so that the rotation of the stirring paddle installed on the stirring shaft is realized.

[0003] The planetary high-speed disperser in the current patent literature has the working principle that the low-speed transmission shaft drives the planetary box to revolve, the planetary box drives the stirring shaft to revolve, and the stirring shaft is driven to rotate by the high-speed transmission shaft.

[0004] Therefore, it is necessary to develop a planetary low-speed mixer in which the revolution and rotation of the stirring paddle are irrelevant, the rotation direction and rotation speed of the stirring paddle can be adjusted independently, so as to adapt to different requirements of the new production process of high-viscosity materials for rotation speed and rotation direction. UTILITY MODEL CONTENTS

[0005] The utility model solves the technical problem of providing a double-control low-speed mixer for high-viscosity materials, in which the rotation direction and rotation speed of the revolution and rotation of the stirring paddle are controlled by two motors, the rotation speed and rotation direction of the revolution and rotation of the stirring paddle are independent and irrelevant, can be adjusted independently, and is especially suitable for stirring materials with high viscosity, high consistency and poor fluidity.

[0006] The technical scheme for solving the above technical problems is: a double-control low-speed mixer for high-viscosity materials, comprising a rack, a planetary box, a solid shaft, a bearing seat and a stirring assembly, wherein the stirring assembly comprises a stirring shaft and stirring paddles installed on the stirring shaft, and further comprising a hollow shaft, a revolution motor and a revolution-around-motor, the hollow shaft is installed on the rack through the bearing seat and the bearing, the lower part of the hollow shaft is connected with the planetary box, the solid shaft is located in the hollow shaft and extends into the planetary box, an intermediate gear is installed on the solid shaft located in the planetary box, an input sprocket I is installed on the upper part of the solid shaft, the input sprocket I is connected with the output shaft of the revolution motor, an input sprocket II is installed on the hollow shaft, the input sprocket II is connected with the output shaft of the revolution-around-motor, the stirring shaft is installed on the planetary box through the bearing, and a planetary gear meshing with the intermediate gear is installed on the stirring shaft located in the planetary box.

[0007] Further, the stirring assembly is provided with two groups, and the stirring shafts of the two groups of stirring assemblies are symmetrically arranged on the two sides of the solid shaft.

[0008] Further, the stirring paddles are square stirring frames, and the two stirring frames are vertically arranged.

[0009] Further, the stirring paddles are butterfly stirring frames or spiral stirring paddles or anchor stirring paddles.

[0010] The transmission structure has two groups, one group is that the revolution-around-motor drives the hollow shaft to rotate through chain transmission, the hollow shaft drives the planetary box fixed thereon to revolve, and the planetary box drives the stirring paddles to revolve; the other group is that the revolution motor drives the solid shaft located in the hollow shaft to rotate through chain transmission, the intermediate gear installed on the solid shaft rotates synchronously to drive the planetary gear on the stirring shaft to rotate, and the stirring paddles rotate. The rotation direction and the rotating speed of the stirring paddles can be independently adjusted, and the rotation direction and the rotating speed of the revolution are not interfered with each other. This transmission combination can independently control the rotation direction and the rotating speed of the planetary box without affecting the rotation direction and the rotating speed of the stirring paddles, that is, the rotation direction and the rotating speed of the revolution and rotation of the stirring paddles can be independently adjusted, and the use process is more flexible. This mixer can meet the speed requirements of different processes in complex production processes, and is particularly suitable for adjusting the rotating speed and the rotating direction of each process in the new production process of high-viscosity materials, and has good stirring and mixing effect for high-viscosity materials.
