[0023] In the above technical solution, by setting a temperature sensor 9, a PLC controller 10 and a control panel 11, the temperature can be preset using the control panel 11. When the temperature sensor 9 detects that the actual temperature in the mixing barrel 16 is higher than the preset temperature, the PLC controller 10 controls the first motor 5 to stop, which can prevent the material stirred and dispersed in the mixing barrel 16 from being damaged in terms of its texture due to excessive temperature.
[0024] In the present invention, a second motor 12 is further provided on top of the L-shaped support plate 2. The second motor 12 is electrically connected to the PLC controller 10. The output shaft of the second motor 12 passes through the L-shaped support plate 2 and is rotatably connected thereto. The bottom end of the output shaft of the second motor 12 is connected to a threaded rod 13.
