DETAILED DESCRIPTION

[0020] The following is a combination of specific implementation cases and attached Figure 1-2 The present invention is further described below, but the present invention is not limited to these embodiments.

[0021] The existing cosmetic variable frequency mixers mostly use single-axis stirring, which has a relatively single mixing direction and is prone to produce centrifugal force, causing the sample liquid to adhere to the inner wall of the sampling tube, resulting in a vacuum in the center, and failing to achieve the purpose of complete mixing.

[0022] The following is an introduction to the double-axis stirring component. Each set of double-axis stirring components includes a first stirring shaft 2 that is rotatably connected to the top of the inner cavity of the mixer body 1 through a bearing, and the first stirring shaft 2 penetrates downwardly through the outer wall of the mixer body 1. The double-axis stirring component also includes a second stirring shaft 6 that penetrates the outer wall of the mixer body 1, and the second stirring shaft 6 is rotatably connected to the outer wall of the mixer body 1 through a bearing. The tops of the outer walls of the first stirring shaft 2 and the second stirring shaft 6 are respectively installed with a second gear 8 and a first gear 7, and the second gear 8 is meshed with the outer wall of the first gear 7. When the second gear 8 rotates, it can drive The first gear 7 rotates in the opposite direction, which can cause the first stirring shaft 2 and the second stirring shaft 6 to rotate in opposite directions.

The driving component also includes a variable frequency motor 5 installed on the top end of the mixer body 1, and the output end of the variable frequency motor 5 is connected to the top end of the outer wall of one of the first stirring shafts 2, wherein the variable frequency motor 5 can be driven by variable frequency as needed, and its model is a common variable frequency motor model on the market, and it is not specifically limited here. The variable frequency motor 5 prompts the first stirring shaft 2 to rotate at a variable frequency to meet the mixing requirements of different stirring speeds of cosmetic sample liquids with different viscosities. The variable frequency motor 5 drives the first stirring shaft 2 and the pulley 3 on the outer wall to rotate, which can prompt the belt 4 to drive the other pulley 3 to rotate in the same direction, so as to prompt the left and right groups of double-axis stirring components to perform synchronous stirring, thereby realizing the synchronous stirring of the two groups of sampling tubes 20.

[0024] In addition, the sampling barrel 20 is movably arranged in the placement cavity on the front side of the mixer body 1 through a lifting mechanism. The lifting mechanism includes a lifting component and a limiting component, and a support plate 16 is connected between the lifting component and the limiting component. The two sampling barrels 20 are symmetrically placed on the left and right sides of the upper surface of the support plate 16.

[0025] The principle of a variable frequency bidirectional dual-axis mixer for stirring the cosmetic sample liquid is as follows:

[0026] Place two sampling barrels 20 on the left and right sides of the upper surface of the support plate 16 respectively, and drive the screw 12 to rotate by rotating the hand lever 14 and the hand wheel 13, thereby causing the first slider 15 on the outer wall of the screw 12 to move upward along the outer wall of the screw 12. At this time, the second slider 19 on the right side of the support plate 16 rises synchronously along the outer wall of the light rod 18, causing the two sampling barrels 20 on the top of the support plate 16 to move upward synchronously until the left and right groups of the first stirring blades 9 and the second stirring blades 10 reach the appropriate positions of the inner cavities of the two sampling barrels 20, and stop rotating the hand lever 14;

[0027] The first stirring shaft 2 connected to its output end is driven to rotate by the turned-on variable frequency motor 5, so as to promote the synchronous rotation of the pulley 3 and the second gear 8 on the outer wall of the first stirring shaft 2, and the rotating pulley 3 promotes the belt 4 on the outer wall to drive another pulley 3 to rotate synchronously in the same direction, so as to realize the synchronous and same-direction rotation of the left and right first stirring shafts 2; the rotating second gear 8 promotes the first gear 7 and the second gear 8 meshingly connected to the outer wall to rotate in opposite directions, thereby promoting the second stirring shaft 6 connected to the outer wall of the second gear 8 and the first stirring shaft 2 to rotate in opposite directions, so as to realize the first stirring blade 9 on the outer wall of the first stirring shaft 2 and the second stirring blade 10 on the outer wall of the second stirring shaft 6 to rotate in opposite directions, and the bidirectionally rotating first stirring blade 9 and second stirring blade 10 can perform bidirectional stirring on the inner cavity of the sampling tube 20 to avoid the phenomenon of central vacuum in a single direction; by setting the left and right groups of the first stirring shaft 2 and the second stirring shaft 6, the synchronous stirring of the left and right groups of the sampling tubes 20 can be realized synchronously, so as to realize the synchronous sampling of two groups of cosmetic sample liquids, which is more representative than single sampling;

[0028] Compared with traditional single-direction stirring and mixing, the utility model can realize bidirectional dual-axis synchronous stirring of the cosmetic sample liquid, effectively avoiding the hollow phenomenon caused by a single direction, further ensuring that the cosmetic sample liquid can be fully mixed, and at the same time can drive the two groups of dual-axis stirring components on the left and right sides to rotate synchronously, so that the left and right groups of sampling tubes 20 can synchronously carry out stirring sampling and detection of the cosmetic sample liquid, and take the average value, which is more representative than a single sampling tube 20.
