[0026] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0027] See also Figure 1 to Figure 2 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0028] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0029] For this example, please refer to Figure 1 The utility model provides an embodiment of a dressing forming structure, which is arranged on a forming plate for forming a dressing sheet, and includes a mounting cavity 320 located on the forming plate and a forming box 321 matched with the mounting cavity 320, a filter screen 323 is arranged at the bottom of the forming box 321, and the top of the forming box 321 is open;

[0030] The installation cavity 320 has bosses 3201 on both sides and a drainage notch 3202 at the outer end. After the molding box 321 is installed in the installation cavity 320, a water outlet channel is formed at the bottom and a molding cavity is formed at the top.

[0031] In the above embodiment, after the molding box 321 is loaded into the mounting cavity 320 of the molding plate, the molding plate is immersed in the pre-prepared homogeneous mixture liquid and the opening of the molding box 321 is facing upward, and then the molding plate is taken out from the homogeneous mixture liquid. Excess water flows away from the filter at the bottom of the molding box 321, and the biological fiber is intercepted by the filter, and then dried, so that the dressing sheet can be obtained simply and efficiently. The biological fiber is a filamentous product metabolized by the fermentation and cultivation process of microorganisms, which presents a 3D interlaced fiber structure. It can be crushed at a speed of 22000-37000rpm to obtain a biological fiber homogenate, and the biological fiber homogenate is mixed with the active ingredient to obtain a homogeneous mixture liquid.

[0032] In this embodiment, an auxiliary heating device 324 is installed in the installation cavity 320. After the forming plate is taken out of the homogenous mixture liquid and the excess liquid is filtered out, the auxiliary heating device 324 can accelerate the drying speed of the remaining biological fiber material, thereby improving the production efficiency of the dressing sheet.

[0033] Furthermore, the auxiliary heating device 324 is a heating wire or a heating sheet attached to the bottom of the installation cavity 320. Figure 1 As shown, after the molding box 321 is installed in the mounting cavity 320 on the molding plate, there is still a distance between the molding box 321 at the bottom of the molding box 321 and the bottom surface of the mounting cavity 320. During filtration, this distance can be used for drainage, and during drying, this distance can prevent the auxiliary heating device 324 from directly contacting the filter screen, and the dressing sheet attached to the filter screen can evaporate moisture from both sides when heated, thereby improving the drying efficiency.

[0034] This embodiment can be found in Figure 2 The filter screen 323 is detachably arranged at the bottom of the forming box 321. As a filtering component, the filter screen 323 may be clogged. The filter screen 323 and the forming box are arranged as two separate parts, which can be easily disassembled, replaced and cleaned.

[0035] In this embodiment, the filter screen 323 is detachably fixed to the bottom of the molding box 321 by magnetic attraction;

[0036] And / or, the molding box 321 is detachably fixed in the installation cavity 320 by magnetic attraction.

[0037] The magnetic structure can reduce the use of screws and snap-on structures, reduce the complexity of the structural design on the filter and the molding box, and facilitate disassembly and cleaning after filtration.

[0038] For this example, please refer to Figure 2On the molding box 321, a baffle 3203 is provided on one side of the installation cavity 320 provided with a drainage notch 3202, and the baffle 3203 covers the top open portion of the molding box 321. The baffle 3203 partially closes the originally open molding box 321, so that when the dressing sheet is fully dried and lightened, it is not easy to be separated from the molding box due to wind force and other reasons during the movement. When the dressing sheet needs to be taken out, it needs to be moved in a specific direction to exceed the baffle.

[0039] For this example, please refer to Figure 2 , on the side of the molding box 321 opposite to the drainage notch 3202 on the installation cavity 320, the bottom of the cavity of the molding box 321 is connected to the top surface of the molding box 321 through the curved surface 3204. After the dressing sheet is dried in the molding box 321, it is only necessary to tilt the molding plate so that the side of the molding box 321 with the baffle 3203 is higher than the side with the curved surface 3204, so that the dressing sheet can automatically slide along the curved surface 3204 and fall into a special receiving device. If the dressing sheet adheres to the filter screen in the molding box 321, it can also be blown off the filter screen by passing gas from the drainage notch 3202 and passing through the filter screen in the reverse direction, so as to achieve shedding. In the above process, the baffle 3203 can also prevent the dressing sheet from flying around and ensure that the dressing sheet always detaches along the curved surface 3204.

[0040] To facilitate understanding of the above solution, the following provides an embodiment of a blowing structure matching the present solution: used to separate the dressing sheet from the dressing forming structure, wherein the multiple forming structures are located on the same forming plate 3. Figure 3-5 The blowing structure includes a blowing plate 4 with a cavity at the bottom. The cavity sidewalls are closed on three sides and one side is open. The forming plate 3 cooperates with the cavity and is inserted into it. On the blowing plate 4, one side in contact with the forming plate 3 is provided with an air outlet duct 40. The wind blows the dressing sheet away from the forming structure. The air outlet duct 40 is provided on the side opposite to the opening of the cavity sidewall. The blowing plate 4 includes a base plate 41 and a sliding plate 42. The sliding plate 42 slides against the bottom of the base plate 41. The sliding plate 42 is connected to the base plate 41 through a first telescopic structure 43. The sliding plate 42 retracts and exposes the cavity when squeezed by the forming plate 3. After the forming plate 3 is loaded into the cavity, the base plate 41 and the sliding plate 42 clamp the forming plate 3. The end of the forming plate 3 is aligned with the air outlet duct 40 of the blowing plate 4.

[0041] The blow-out plate 4 is provided with an air inlet 44. The blow-out plate 4 is hollow and is formed with a plurality of sheet-like layers to form an air outlet duct 40. A heating wire is arranged in the sheet-like layer of the air outlet duct 40. On the blow-out plate 4, on the side where the cavity opens, a sliding structure is arranged at the end of the blow-out plate 4. The sliding structure is a smooth arc chamfer or a rolling shaft 46. Figure 5 When the gas is blown out from the air outlet duct 40, it passes through the filter in the reverse direction, and the dressing sheet can be separated from the filter to prevent adhesion.

[0042] As for the dressing forming structure, further, the baffle 3203 and the forming box 321 are both made of stainless steel. The baffle 3203 and the forming box 321 will be soaked in the homogeneous mixture raw material liquid, and the working state is in a humid environment for a long time. Setting them to stainless steel can prevent rust and reduce the impact on the liquid raw material.

[0043] Further, this embodiment can be referred to Figure 1 and Figure 2 , the outer surface of the baffle 3203 is provided with a temperature-variable ink coating area 3205. In the production process of the dressing sheet, the homogenous mixture raw material liquid needs to maintain a certain temperature; when the dressing sheet is dried, a certain drying temperature must also be maintained. By providing the temperature-variable ink coating area 3205 on the outer surface of the baffle 3203, the temperature change can be observed intuitively and adjusted in time. Although a temperature sensor can also be used, it is not suitable for the actual working scene of the molding box 321 in this scene because it requires corresponding matching circuits, etc.

[0044] In this embodiment, the pore size of the filter 323 is 0.02-0.05 mm. A stainless steel filter with a pore size of 0.02-0.05 mm can be used and fixed at the bottom of the molding box 321. When the biofiber homogenate liquid passes through the filter, a layer of biofiber wet film will be obtained on its surface. Through the above steps, without additional pressure and drying, only the sieved water of the filter, the filter hole plate or its combined components is passed through, and the moisture content of the obtained biofiber wet film is 10-20%. Then the above biofiber wet film is dried, and the obtained biofiber dressing has good flatness and stable quality.

[0045] In summary, the utility model effectively overcomes various shortcomings in the prior art, can produce beneficial technical effects, and has significant progress.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
