Abstract

The present invention provides a mixing plant which the mixing blade is not only rotation but also revolution. In order to resolve the problem of the complicated structure of the present mixing plantmachinery, complicated speed detect circuit controlling the rotation and high cost of the mixing device caused by speed detecting sensor, the invention provides a mixing device, including a driving motor, a speed control device of driving motor, a support frame, a mixing blade, a planetary gear train and a underdriving gear set driven by the driving motor, the driving motor drives planetary gear train via underdriving gear set, the mixing blade mounted on the planetary gear train is rotation and revolution; the outer edge of the planetary gear train is distributed with double wedge, the speedcontrol device counts the time of the double wedge passing the signal switch by signal switch to calculate the speed of the rotary disk, detecting and controlling the speed of the mixing device. The mixing device has a simple structure, a compact speed detecting circuit and a sensor need not detect the speed, and a lower cost.

Description

technical field [0001] The invention relates to a stirring device, more specifically, to a stirring device in which the stirring blades both rotate and revolve. Background technique [0002] In order to make the stirring device have a higher stirring efficiency, the stirring blades of the stirring device generally adopt two kinds of stirring modes, that is, the stirring blades perform orbital motion while rotating. The current stirring device realizes the stirring mode of both self-rotation and revolution by driving two drive motors separately. Using two drive motors and two sets of drive systems makes the structure of the stirring device complicated and the manufacturing cost high. At present, there is also a motor for driving, but most of them have the problems of complex structure and high manufacturing cost. In addition, if the current stirring device is to quantitatively detect and control the relevant rotational speed, the circuit to realize the speed detection is usu...
