[0027] Working principle: In use, an appropriate amount of raw materials are added to the mixing box 3. Then, the servo motor 11 is started via the control panel 6. The rotation of the power output shaft of the servo motor 11 drives the rotating shaft 12 fixed at the end of the power output shaft of the servo motor 11 to rotate, thereby causing the two take-up rollers 13 to rotate. Under the action of gravity, the top cover 7 moves stably downward under the connection of the connecting plate 8 and the limiting position of the first slide groove and the first slider, so that the two locking blocks fixed on the top cover 7 are respectively inserted into the inner cavity of the adjacent locking groove. Then, the drive motor 17 is started via the control panel 6. The rotation of the power output shaft of the drive motor 17 drives the first worm gear 18, which is fixed to the end of the power output shaft of the drive motor 17, to rotate. This, in turn, causes the straight rod 20 to rotate via the first worm wheel 19. The second single-grooved pulley, fixed to the straight rod 20 and driven by the transmission belt 22, rotates. The second worm gear 23, fixed to the second single-grooved pulley, causes the second worm wheel 24 to rotate, which in turn causes the square tube 25 to rotate, thus rotating the square rod 26. Several stirring blades 31 hinged to the square rod 26 mix the slurry. The rotation of the straight rod 20 causes the fixed sleeve... The two cams 36 on the straight rod 20 rotate, causing the sliding plate 21 to move up and down reciprocally under the limit of the second slide groove and the second slider, and with the cooperation of the first spring 28. This causes the square rod 26 on the sliding plate 21 to move up and down reciprocally, thereby causing several stirring blades 31 to move up and down reciprocally, facilitating the mixing of the slurry at the bottom of the mixing chamber 3. Through the observation window, the two electric telescopic rods 30 are activated via the control panel 6. The two electric telescopic rods 30 push the adjacent vertical plates 33 to move to opposite sides under the limit of the adjacent third slide groove and the third slider. With the cooperation of the movable shaft fixed on the adjacent vertical plates 33 and the adjacent arc groove, the angle of the two stirring blades 31 at the top can be changed, and the angle of several stirring blades 31 can be changed through the adjacent movable rod 32, thereby improving the mixing effect of the device. After mixing for a period of time, the first solenoid valve and the second solenoid valve can be opened via the control panel 6 to check the mixing status. After mixing is completed, the stirring blades 31 are moved out of the mixing chamber 3 via the adjustment mechanism for easy cleaning and to reduce the workload of the workers.
