Description

Technical Field

[0001] This utility model relates to the field of hydrogel preparation, and in particular to a high-efficiency mixing device for hydrogel preparation. Background Technology

[0002] Hydrogels, as polymer materials with a three-dimensional network structure, have been widely used in various fields such as biomedicine, tissue engineering, cosmetics, and food industry. In the biomedical field, hydrogels can be used as drug delivery carriers and wound dressings; in the cosmetics industry, they are often used in face masks and skin care products to improve their moisturizing and adhesion properties. With the continuous growth of demand for hydrogels in various industries, efficient and stable hydrogel forming equipment has become crucial to ensuring production quality and efficiency.

[0003] In the preparation of hydrogels, it is usually necessary to mix the raw materials. During the mixing process, some equipment adopts a simple stirring structure, the installation method of the top cover is not stable enough, and the mixing tank does not have a heating function, which cannot effectively promote the dissolution of raw materials and greatly reduces the mixing effect. In order to address this technical problem, this application proposes a high-efficiency mixing device for hydrogel preparation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency mixing device for hydrogel preparation. The top cover is secured to the outside of the lead screw by two fixing blocks and then tightened with a knob, thus stably installing the top cover on the top of the mixing tank. This prevents raw materials from splashing out due to shaking during stirring. A motor-driven rotating rod drives the stirring blades for mixing, while a circulating water pump delivers hot water to heat the raw materials, accelerating dissolution and improving mixing quality. A peristaltic pump transports the stirred hydrogel into the bottom mold. Pressing the fixing rod causes a moving plate to drive a pressing block to extrude and shape the hydrogel. Automatic reset is achieved through spring elasticity, and the pressing force is limited to ensure the molding effect.

The mixing tank 4 has a double helix structure. Rotating the rotating rod 17 causes the stirring blades 16 to mix the raw materials. A bottom plate 1 is provided at the bottom of the mixing tank 4. A bottom mold 9 is fixedly connected to the top right side of the bottom plate 1. An extrusion groove is formed in the middle of the bottom mold 9. A pressing block 21 is provided on the top of the bottom mold 9. The size of the pressing block 21 matches the size of the extrusion groove. A movable plate 12 is fixedly connected to the top of the pressing block 21. A top plate 13 is provided on the top of the movable plate 12. A sliding connection is made in the middle of the top plate 13. The fixed rod 14 can push the moving plate 12 downward by pressing the fixed rod 14 downward, so that the moving plate 12 moves with the pressing block 21. It can extrude and mold the stirred hydrogel by cooperating with the extrusion groove. The four corners of the moving plate 12 are slidably connected with limit rods 10, which can limit the movement of the moving plate 12. The top end of the limit rod 10 is fixedly connected to the bottom of the top plate 13, and the bottom end of the limit rod 10 is fixedly connected to the bottom plate 1.

[0023] Reference Figure 1-3The limiting rod 10 has a spring 20 sleeved on its outer wall.
