[0001] The invention relates to the technical field of water solubility detection of chitosan oligosaccharide, in particular to a water solubility detection device of chitosan oligosaccharide capable of batch testing. Background Art

[0002] As an important functional oligosaccharide, chitosan oligosaccharide is widely used in food, medicine, cosmetics and other fields. The water solubility of chitosan oligosaccharide is one of its important physical and chemical properties, which directly affects its solubility and stability in solution. The existing water solubility test of chitosan oligosaccharide is to add the powdered chitosan oligosaccharide sample and solvent into the sample container, mix the sample thoroughly, and then use the photoelectric sensor to detect the transmittance of the mixed solution. The signal processor converts the transmittance signal into a water solubility parameter to complete the test. However, after the chitosan oligosaccharide powder is added to the solvent, it is easy to float on the surface of the solvent, resulting in insufficient contact with the solvent and low experimental efficiency.

[0003] Therefore, a chitosan oligosaccharide water solubility detection device capable of batch testing has been developed, which can press chitosan oligosaccharide powder into a solvent to ensure that the powder and the solvent are fully contacted and dissolved, thereby improving experimental efficiency.

The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0032] A chitosan oligosaccharide water solubility detection device capable of batch testing, such as Figure 1-Figure 10 As shown, it includes a base 1, an experimental cup 2, a fixing frame 3, a stirring mechanism 4 and an auxiliary mechanism 5. The experimental cup 2 is placed on the upper left side of the base 1, and the fixing frame 3 is connected to the upper middle side of the base 1. The fixing frame 3 is provided with six arc-shaped clips for fixing the experimental cup 2. The fixing frame 3 is provided with a stirring mechanism 4, and the stirring mechanism 4 is provided with an auxiliary mechanism 5.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the stirring mechanism 4 includes a cylinder 41, a lifting frame 42, a motor 43, a first gear 44, a stirring frame 45, a connecting shaft 451, a second gear 46 and a latch 47. The cylinder 41 is connected to the upper side of the fixed frame 3, the lifting frame 42 is connected to the telescopic end of the cylinder 41, the motor 43 is connected to the upper middle side of the lifting frame 42, the first gear 44 is connected to the output shaft of the motor 43, six stirring frames 45 are rotatably connected to the lifting frame 42, the upper sides of the stirring frames 45 are all slidably connected to the connecting shafts 451, the upper parts of the connecting shafts 451 are all connected to the second gears 46, the second gears 46 are all meshed with the first gears 44, the upper parts of the stirring frames 45 are all clamped with latches 47, and the latches 47 are all clamped with the adjacent connecting shafts 451.

[0034] like Figure 1 , Figure 5 and Figure 6As shown, the auxiliary mechanism 5 includes a guide frame 51, a lower pressure frame 52, a rotating frame 53, a filter frame 54, a limit plate 55 and a spring 56. Six guide frames 51 are connected to the lower side of the lifting frame 42. The guide frames 51 are slidably connected to the lower pressure frames 52. The upper part of the stirring frame 45 is connected to the rotating frame 53. The rotating frame 53 is located below the pin 47. The rotating frame 53 is squeezed and matched with the adjacent lower pressure frame 52. The lower side of the lower pressure frame 52 is rotatably connected to the filter frame 54. The middle part of the stirring frame 45 is connected to the limit plate 55. The filter frame 54 is slidably connected to the adjacent limit plate 55. Two springs 56 are connected between the lower pressure frame 52 and the connected guide frame 51.

[0035] When using the present invention, first place the base 1 in the chitosan oligosaccharide solubility detection area, then place the experimental cup 2 filled with the solvent on the base 1, fix the experimental cup 2 by the arc clamp on the fixing frame 3, then add the chitosan oligosaccharide powder into the experimental cup 2, start the cylinder 41, drive the lifting frame 42 to move downward, so that the stirring frame 45 moves downward into the experimental cup 2, then start the motor 43, drive the first gear 44 to rotate, so that the first gear 44 and the second gear 46 engage and move, drive the connecting shaft 451 to rotate, so that the stirring frame 45 rotates to stir the sample, when the stirring frame 45 does not need to rotate, the pin 47 can be removed, and then the connecting shaft 451 can be moved and adjusted to make the second gear 46 disengage from the first gear 44, and after adjustment, the connecting shaft 451 can be re-fixed by the pin 47. When the stirring frame 45 rotates, it drives the rotating frame 53 to rotate. When the rotating frame 53 contacts the lower pressing frame 52, it squeezes the lower pressing frame 52 to move downward, so that the filter frame 54 moves downward, and the spring 56 is squeezed and contracted. When the rotating frame 53 is separated from the lower pressing frame 52, the spring 56 rebounds, so that the lower pressing frame 52 is reset, so that the filter frame 54 is reset. Such a cycle makes the filter frame 54 move up and down in the sample, and the chitosan oligosaccharide powder on the surface of the solvent is pressed into the solvent. When the stirring frame 45 rotates, it drives the limiting plate 55 to rotate, so that the filter frame 54 rotates. Thereby, the chitosan oligosaccharide powder can be pressed down into the solvent, ensuring that the powder is fully contacted and dissolved with the solvent, and improving the experimental efficiency.

[0036] like Figure 1 and Figure 7 As shown, it also includes a feeding mechanism 6, which includes a support frame 61, a storage tank 62, a discharge pipe 63, a solenoid valve 64 and a cup cover 65. The support frame 61 is connected to the upper side of the lifting frame 42, and the storage tank 62 is connected to the upper middle side of the support frame 61. A material cover is provided on the upper side of the storage tank 62 for easy sealing, and a handle is provided on the upper side of the material cover for easy grasping and opening. Six discharge pipes 63 are connected to the lower part of the storage tank 62, and the discharge pipes 63 are each provided with a solenoid valve 64. Six cup covers 65 are connected to the lifting frame 42, and the stirring frames 45 are rotatably connected to adjacent cup covers 65, and the solenoid valves 64 are connected to adjacent cup covers 65.

[0037] By using the feeding mechanism 6 of the device, chitosan oligosaccharide powder can be automatically added. When the lifting frame 42 moves downward, the cup cover 65 moves downward so that the cup cover 65 contacts and closes the experimental cup 2 to prevent the sample from splashing out. When chitosan oligosaccharide powder needs to be added to the experimental cup 2, the solenoid valve 64 is opened to allow the chitosan oligosaccharide powder in the storage tank 62 to enter the experimental cup 2 through the discharge pipe 63, thereby playing the role of automatically adding chitosan oligosaccharide powder, saving manpower, and improving experimental efficiency.

[0038] like Figure 1 and Figure 8 As shown, a speed regulating mechanism 7 is also included, and the speed regulating mechanism 7 includes a support rod 71, a third gear 72 and a fourth gear 73.

The lower part of the connecting shaft 451 is connected to the fourth gear 73.

[0039] By using the speed regulating mechanism 7 of the device, the rotation speed of the connecting shaft 451 can be adjusted. When the rotation speed of the connecting shaft 451 needs to be increased, the latch 47 can be removed, and the connecting shaft 451 can be moved and adjusted to disengage the second gear 46 from the first gear 44 and to engage the fourth gear 73 with the third gear 72. After the adjustment, the connecting shaft 451 is re-fixed by the latch 47. When the first gear 44 rotates, it engages with the third gear 72, so that the third gear 72 engages with the fourth gear 73, driving the connecting shaft 451 and the stirring frame 45 to rotate, thereby playing a role in being able to adjust the rotation speed of the connecting shaft 451 to adapt to the mixing requirements of different samples.

[0040] like Figure 1 and Fig. 9 As shown, a temperature control mechanism 8 is also included, and the temperature control mechanism 8 includes a fixed plate 81, a temperature controller 82 and a heating tube 83. Six fixed plates 81 are connected inside the base 1, and the outside of the fixed plates 81 are connected to the temperature controller 82. The upper side of the fixed plates 81 is connected to the heating tube 83, and the temperature controller 82 is connected to the adjacent heating tube 83 through electric wires.

[0041] The temperature control mechanism 8 of the device can be used to adjust the temperature of the sample during mixing. After the sample is added to the experimental cup 2, the heating tube 83 is controlled by the temperature controller 82 to heat the experimental cup 2, thereby enabling the sample to be mixed at a specific temperature and avoiding measurement errors caused by temperature changes.

[0042] like Figure 1 and Fig.10As shown, it also includes an extrusion mechanism 9, which includes a support plate 91 and an extrusion plate 92. Four support plates 91 are connected to the middle of the stirring frame 45, and the support plates 91 are all located below the limiting plate 55. Extrusion plates 92 are connected between the support plates 91 connected to the same stirring frame 45, and the extrusion plates 92 are all located above the adjacent filter frames 54.

[0043] The extrusion mechanism 9 of the device can be used to extrude the chitosan oligosaccharide powder to disperse it. The filter frame 54 moves back and forth up and down while cooperating with the extrusion plate 92 to extrude the chitosan oligosaccharide powder, thereby further dispersing the chitosan oligosaccharide powder and improving the dissolution efficiency and uniformity of the chitosan oligosaccharide powder.
