Description

Technical Field

[0001] The invention relates to the technical field of mixing devices, in particular to a mixing device for processing medicinal creams. Background Art

[0002] Our company produces a medicinal cream for treating athlete's foot. During the production process, the raw materials, including oils, waxes, emulsifiers, moisturizers, active pharmaceutical ingredients, preservatives, fragrances, and pigments, must be mixed and stirred. During mixing, the raw materials must be stirred slowly to prevent excessive stirring, which could introduce large amounts of air into the cream and form bubbles. These bubbles disrupt the cream's uniform structure and reduce its stability. When filling bottles, the bubbles occupy a certain volume of the cream, making it difficult to control the amount filled in a fixed-volume bottle. However, during the mixing process, heated oils, waxes, and other ingredients poured into the mixing device may not be mixed promptly upon melting, or the emulsifier may be unevenly mixed with the oil and water phases. This can lead to localized areas of excessively high concentrations, resulting in lumps. Since stirring can only be slow, the stirring mechanism in the mixing device in the prior art is unable to break up the lumps, affecting the quality of the cream during mixing.

[0025] The pressing member includes a sleeve 19, and a lever 20 is movably passed through the center of the sleeve 19. The upper end of the lever 20 is hemispherical, which is convenient for the lever 20 to slide and contact along the bottom of the semicircular tube 17. In the initial state, the upper end of the lever 20 is lower than the upper end of the semicircular tube 17. A circular limit plate 21 is provided in the sleeve 19, and the circular limit plate 21 is fixed on the lever 20. The circular limit plate 21 rises and falls with the rise and fall of the lever 20. A spring 22 is provided in the sleeve 19, and the spring 22 is sleeved on the lever 20. One end of the spring 22 is connected to the circular limit plate 21 and the other end is connected to the inner wall of the bottom of the sleeve 19. When the circular limit plate 21 descends, the spring 22 is compressed, and a shearing piece is provided at the lower end of the lever 20.

When the shift lever 20 contacts the semicircular tube 17, the two scissor blades 28 rotate and gradually lean against each other until they cross, realizing the shearing action. This execution action is the same as that of ordinary scissors.

[0027] The bottom of the mixing tank 1 is funnel-shaped, which is convenient for the cream in the mixing tank 1 to be discharged. A group of brackets 32 are distributed on the mixing tank 1, which is fixed on the high platform through the brackets 32, so that the mixing tank 1 is elevated and fixed.

[0028] The working principle of the present invention is as follows: the cream raw materials are put into the mixing tank 1 through two feeding ports 4, the reduction motor 10 is started, the reduction motor 10 drives the stirring rod 12 to rotate, the stirring rod 12 drives the shaft sleeve 13 and the stirring blade 14 to rotate, so that the stirring blade 14 stirs the cream raw materials at a slow speed, and the stirring rod 12 also drives the fixed sleeve 16, the connecting rod 16 and the semicircular tube 17 to rotate, wherein the cream raw materials are continuously put into the mixing tank 1, and the highest liquid level of the cream raw material liquid in the mixing tank 1 is lower than the position of the semicircular tube 17. When the semicircular tube 17 rotates and contacts the lever 20, as the curvature of the bottom of the semicircular tube 17 decreases from high to low, the lever 20 is pressed and gradually decreases, and the lever 20 drives the circular limit plate 21 to decrease, and the spring When the lever 22 is compressed, the lever 20 also drives the slats 23 to descend, and the slats 23 drive the connecting rod 26 to move downward, and the connecting rod 26 drives the first cap nail 25 to rotate on the second bearing 24, and the other end of the connecting rod 26 drives the second cap nail 27 to rotate on the scissor blade 28, and the scissor blade 28 drives the third cap nail 29 to rotate on the third bearing 30. The two opposing scissor blades 28 gradually lean against each other and cross each other to perform a shearing action, shearing the cream raw materials that are undergoing centrifugal motion during stirring, and breaking up the lumps in the cream raw materials. When the lever 20 leaves the bottom of the semicircular tube 17, the spring 22 rebounds, driving the circular limit plate 21 and the lever 20 to rise, so that the scissor blades 28 are restored to the open state, thereby realizing that the scissor blades 28 continuously perform a shearing action.
