At the same time, different lipid components are injected into the corresponding heating bins from different injection pipes 19, and clean water is injected into the water bath 5. After the clean water is heated, a constant temperature water bath heating process is realized. After the injected lipid components are heated, they are directly transported to the inside of the mixing tank 1, and mixed again to finally complete the preparation process of the colloidal solution. After the preparation is completed, it can be directly discharged from the inside of the discharge pipe 3. In the later stage of mixing, the scraper assembly 26 is placed to achieve the purpose of collecting the particles adhered to the surface of the mixing tank 1 and the stirring mechanism 9.

[0037] In this embodiment, the water bath 5 is provided with a top heating chamber 15 and a bottom heating chamber 16, and the surfaces of the top heating chamber 15 and the bottom heating chamber 16 are welded and fixed to the inner wall of the water bath 5 through a support column 17. There are two partitions 13, and an interlayer 14 is provided between the partitions 13. A second heat conducting plate 40 is embedded in the middle of the surface of the partition 13, and a docking hole 21 is provided at one end of the partition 13. Both ends of the top heating chamber 15 and the bottom heating chamber 16 are respectively connected to a guide channel 18 and a delivery pipeline 8, and the top side of the guide channel 18 is connected to an injection pipeline 19, and the top and bottom spaces of the partition 13 are connected through the docking hole 21.

[0038] Specifically, the interior of the water bath 5 is divided into a double-layer cavity by the partition 13. After the different lipid components are transported from the injection pipe 19 to the interior of the guide channel 18, they can flow along the corresponding bottom heating chamber 16 and the top heating chamber 15 respectively. During the flow, the constant temperature hot water inside the water bath 5 is used to achieve the purpose of heating, and different lipid components will flow through the heating chambers at different heights, thereby providing heating environments in different areas inside the single water bath 5, and finally each lipid component is discharged from different transport pipes 8.

[0039] In this embodiment, the regulating mechanism 6 includes a rotating disk 34, a blocking plate 37 and a first heat conducting plate 38. The bottom of the rotating disk 34 is integrally formed with a rotating shaft 35. An extension plate 36 is welded to the surface of the rotating shaft 35. The end of the extension plate 36 is integrally formed with a blocking plate 37. The first heat conducting plate 38 is installed at one end of the blocking plate 37. A connecting hole 39 is opened on the surface of the blocking plate 37. The bottom of the rotating shaft 35 is embedded in the bottom of the inner wall of the switching box 4 through a bearing. The blocking plate 37 and the first heat conducting plate 38 are both embedded in the interior of the interlayer 14. The connecting hole 39 is used to connect and align with the two docking holes 21. The side of the water bath 5 is provided with an outer rotating groove 20, the surface of the switching box 4 is provided with an inner rotating groove 10, the extension plate 36 passes through the inner rotating groove 10 and the outer rotating groove 20 in turn, the blocking plate 37 is used to seal the docking hole 21, the first heat conducting plate 38 is used to contact and fit with the two second heat conducting plates 40, and the bottom of the water bath 5 is embedded with an electric heating wire. The partition 13 is divided into two cavity areas, and different lipid components are flow-heated from different heating chambers. The hot water heat transfer state of the top and bottom layers is switched by the regulating mechanism 6, so that the heating needs of multiple lipid components can be provided by only a single water bath heating device, reducing the equipment cost.

[0040] Specifically, by controlling the rotating disk 34 to rotate, the extending plate 36 can be driven to rotate by means of the rotating shaft 35, and the extending plate 36 drives the end blocking plate 37 and the first heat conducting plate 38 to rotate along the interlayer 14 inside the partition 13. When the first heat conducting plate 38 is rotated to the area of ​​the docking hole 21, the blocking plate 37 is inside the extension channel 7, and the first heat conducting plate 38 and the second heat conducting plate 40 are staggered with each other. Therefore, the clean water at the bottom of the partition 13 is in a heat preservation state and does not transfer heat with the cavity at the top. When the rotating disk 34 drives When the sealing plate 37 is rotated until the connecting hole 39 is aligned with the docking hole 21, the water at the bottom and top of the partition 13 are connected to realize the flow exchange process, and the first heat conducting plate 38 and the second heat conducting plate 40 are in contact with each other. Therefore, the electric heating wire at the bottom of the water bath 5 can directly control the temperature inside the entire water bath 5 synchronously, and can also control the connecting hole 39 and the docking hole 21 to be staggered, and the first heat conducting plate 38 and the second heat conducting plate 40 are partially in contact with each other, so that the water bath temperature of the top heating chamber 15 can be controlled to be lower than the water bath temperature of the bottom heating chamber 16.

[0041] In this embodiment, the stirring mechanism 9 includes a motor 22 and a rolling sleeve 25. The motor 22 is screwed on the surface of the mixing tank 1. The output end of the motor 22 is inserted with a drive shaft 23. The side of the drive shaft 23 is welded with a stirring rod 24. The surface of the stirring rod 24 is sleeved with a rolling sleeve 25. The scraper assembly 26 includes a vertical filter 27, a filter tank 28 and a top plate 29. A guide inclined plate 30 is installed on one side of the filter tank 28, and a scraper plate 33 is integrally formed on the other side of the filter tank 28. The bottom of the filter tank 28 is paved with a bottom filter 31. The side of the vertical filter 27 is welded and fixed to the inner wall of the filter tank 28, the top plate 29 is fixed to the top of the vertical filter 27, a magnetic plate 32 is attached to the top of the top plate 29, the bottom filter 31 is pressed against the bottom of the inner wall of the mixing tank 1, the scraper plate 33 is in contact with the surface of the rolling sleeve 25, and the top of the scraper plate 33 is flush with the top of the rolling sleeve 25. The stirring mechanism 9 drives the multiple rolling sleeves 25 at the bottom to rotate along the bottom of the mixing tank 1, so that the hydrophilic polymer inside can be provided with a rolling effect during the mixing process, which accelerates the efficiency of mixing the hydrophilic polymer with water, improves the efficiency of production and processing, and can quickly dissolve the particles in the colloidal solution.

[0042] During the stirring process, the scraper assembly 26 is rotated in coordination with the stirring, so that the particulate impurities adhered to the bottom of the inner wall of the mixing tank 1 and the surface of the rolling sleeve 25 can be collected during the stirring process, thereby improving the purity of the colloidal solution, and the particles that are always present can also be discharged in a centralized manner later. Specifically, after starting the motor 22, the motor 22 drives the drive shaft 23 to rotate, and the drive shaft 23 drives the stirring rod 24 to rotate, so that the rolling sleeve 25 part can rotate along the bottom end of the inner wall of the mixing tank 1. This process can crush and crush the particles in the solution and accelerate the dissolution process with water. After the scraper assembly 26 is placed from the inside of the lifting channel 11 to the inside of the mixing tank 1, the rolling roller is against the outer side of the scraper plate 33, and the entire scraper assembly 26 can be pushed. With the help of the scraper assembly 26, the solution inside the mixing tank 1 can be guided toward the top along the guide inclined plate 30, and the vertical filter screen 27 is used to accumulate the particles in the internal solution in the filter tank 28, and the impurity particles on the surface of the rolling sleeve 25 are scraped by the scraper plate 33 and collected into the inside of the filter tank 28. After the subsequent rotation until the magnetic suction plate 32 is adsorbed and docked with the bottom of the lifting plate 12, the scraper assembly 26 can be directly pulled out from the outside with the help of the lifting plate 12 for cleaning.

[0043] This embodiment also provides a preparation method using the above preparation device, comprising the following steps:

[0044] Step 1: slowly add the hydrophilic polymer into the water, and stir it using the stirring mechanism 9 inside the mixing tank 1. As the stirring proceeds, the hydrophilic polymer gradually dissolves in the water to form a uniform colloidal solution. The stirring process continues for 15 minutes until there are no obvious particles in the solution;

[0045] Step 2: inject the lipid components and additives into the water bath 5 for heating, and control the water bath temperature of the heating chamber where the different lipid components are located by the regulating mechanism 6. The lipid components in this embodiment use vaseline and lanolin materials;

[0046] Step 3: independently controlling the temperature of the lipid component and the additive, slowly adding the heated lipid component and the additive to the prepared hydrophilic polymer colloid solution, and increasing the stirring speed at the same time, so that the lipid component is evenly dispersed in the colloid solution to form a stable emulsion-like mixture;

[0047] Step 4: Continue stirring to evenly disperse the lipid components in the colloidal solution to form a stable emulsion-like mixture;

[0048] Step 5: Pour the emulsion mixture into a pre-prepared molding mold and mold it under fixed temperature and pressure conditions. The temperature is maintained at 40-60°C, and the pressure is adjusted according to factors such as the size of the mold and the thickness of the dressing. In this embodiment, it is set to 0.2MPa. The molding time is 20 minutes, so that the dressing is fully cured and reaches the required shape and strength;

[0049] Step 6: After the formed dressing is taken out of the mold, it is cut to remove the irregular edges and obtain a dressing of the required size. If active ingredients such as antimicrobial agents are added to the dressing, quality testing is carried out later. The testing process includes the release of silver ions to ensure that the performance of the dressing meets medical standards.
