Description

Technical Field

[0001] The utility model relates to the field of hydrogel preparation devices, in particular to a hydrogel preparation device. Background Art

[0002] Hydrogel is a type of extremely hydrophilic three-dimensional network structure gel. It swells rapidly in water and can retain a large volume of water in this swollen state without dissolving. Due to the existence of a cross-linked network, hydrogel can swell and retain a large amount of water. The amount of water absorbed is closely related to the degree of cross-linking. The higher the degree of cross-linking, the lower the water absorption. This property is very similar to a soft tissue, so the application range of hydrogel is very wide. It can be used as a carrier to encapsulate drugs so that the drugs can exert more efficient medicinal effects.

[0003] There are many methods for preparing hydrogels, including free radical polymerization, temperature-sensitive method, ion exchange method, microemulsification method and photopolymerization method, which need to be comprehensively considered according to the characteristics of the materials. The most commonly used method is free radical polymerization. Water-soluble monomers and cross-linking agents are added to the aqueous solution. After adding the initiator, a hydrogel is formed through a free radical polymerization reaction. However, the preparation and production process of hydrogels require different viscosity. Traditional preparation equipment can only perform viscosity testing after the hydrogel is produced, which may lead to waste of raw materials and relatively high costs. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a hydrogel preparation device comprises a preparation barrel 1, wherein a stirring rod 2 is arranged inside the preparation barrel 1, and stirring blades are arranged on the surface of the stirring rod 2 and located inside the preparation barrel 1, and a sealing cover 3 is installed on the surface of the preparation barrel 1, and the top of the stirring rod 2 extends to above the sealing cover 3, and the sealing cover 3 has a component for rotating the stirring rod 2, and a detection substrate 4 is sleeved on the surface of the stirring rod 2, which can move on the surface of the stirring rod 2 and can directly float on the surface of the hydrogel, and a tension detector 5 is installed on the surface of the sealing cover 3, and a connecting component is installed on the surface of the detection substrate 4, and the connecting component is used to connect the tension detector 5 and the detection substrate 4, and the connecting component enables the detection substrate 4 to move, and the maximum tension detected by the tension detector 5 is the viscosity of the hydrogel.

[0021] The connecting assembly includes a gear rod 6, one end of which movably penetrates the sealing cover 3 and is connected to the surface of the detection substrate 4. A motor 7 is installed on the surface of the sealing cover 3. A first gear 8 is fixedly sleeved on the surface of the output shaft of the motor 7. The first gear 8 is engaged with the gear rod 6. The rotation of the motor 7 can drive the gear rod 6 to move, and the gear rod 6 drives the detection substrate 4 to move upward. During the process, the gear rod 6 pulls the tension detector 5 to move.

[0022] There are two gear rods 6, which are arranged on both sides of the stirring rod 2. The teeth of the gear rod 6 face the same direction. A mounting frame 9 is fixed to the surface of the sealing cover 3. The first gear 8 is movably mounted inside the mounting frame 9 through a circular shaft 10. A second gear 11 is fixedly sleeved on the surface of the circular shaft 10. The two second gears 11 are connected by a toothed belt 12. The tension detector 5 is installed on the surface of the mounting frame 9, and the output shaft of the tension detector 5 is fixed to the surface of the gear rod 6.

[0023] The motor 7 drives one of the circular shafts 10 to rotate, thereby causing the corresponding second gear 11 to rotate. Through the meshing action of the toothed belt 12, the two circular shafts 10 can rotate at the same time. At this time, the two first gears 8 can also rotate, indirectly causing the two gear rods 6 to move at the same time. At this time, during the stretching of the detection substrate 4, the pulling force on the surface of the detection substrate 4 is symmetrical, so no tilt occurs, thereby ensuring the accuracy of the detection.

[0024] The stirring blades on the surface of the stirring rod 2 are provided with a large number of through holes, which can allow the colloid raw materials to flow and move, ensuring sufficient stirring.

[0025] The surface of the detection substrate 4 is exactly the same as the opening area of ​​the preparation barrel 1, and the shape is also exactly the same. At this time, the detection substrate 4 isolates the raw materials from the air, ensuring that during the stirring process, the influence of oxygen on the initiator is reduced, ensuring the normal cross-linking reaction.

[0026] A slide groove 13 is provided at the end of the gear rod 6, and a T-shaped rod 14 is provided inside the slide groove 13. The lower end of the T-shaped rod 14 is fixed to the surface of the detection substrate 4. The inner wall shape of the slide groove 13 is adapted to the shape of the T-shaped rod 14 to ensure that the detection substrate 4 has a certain space to move. At this time, during the stirring process, the tension value of the tension detector 5 will not change.

[0027] It should be noted that the utility model is a hydrogel preparation device. When in use, the motor 7 drives one of the circular shafts 10 to rotate, so that the corresponding second gear 11 rotates. Through the meshing action of the toothed belt 12, the two circular shafts 10 can be rotated at the same time. At this time, the two first gears 8 can also rotate, indirectly causing the two gear rods 6 to move at the same time. The gear rod 6 drives the detection substrate 4 to move upward. During the process, the gear rod 6 pulls the tension detector 5 to move, and the maximum tension detected by the tension detector 5 is the viscosity of the hydrogel.
