[0002] An important function of modern wound dressings is that they replace the important functions of damaged skin and continue to work until the wound heals and the skin lesions heal. They have the functions of resisting contact damage, pollution and chemical stimulation, secondary infection, dryness and loss of body fluids. In addition to providing comprehensive protection for wounds, they can also actively affect the wound healing process through debridement or additional drugs, creating a microenvironment that promotes wound healing.

[0003] Modern dressings have begun to use emerging materials such as biofibers, which are metabolites of microbial fermentation and culture processes, have good moisturizing, breathability and skin-friendliness, and have better efficacy. This type of dressing has better efficacy, but lacks supporting high-efficiency production equipment.

[0004] Different from the production method of traditional dressings, this kind of dressing needs to first break up the raw material of biocellulose film to obtain a biofiber homogenate during the production process; mix the biofiber homogenate with the active ingredient to obtain a homogenous mixture liquid; lay the homogenous mixture on the filter element, and perform a dehydration step at room temperature and normal pressure to obtain a biofiber wet film; finally, dry the biofiber wet film at a suitable temperature to obtain a biofiber dry film dressing sheet. During production, the dressing needs to be filtered, formed, dehydrated, and dried. The above steps are performed in the same molding mold. After the above production steps, the dressing sheet is very easy to adhere to the molding mold and requires physical contact to be removed, which increases the complexity of the process and easily causes the dressing sheet to be contaminated.

[0024] 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.

[0025] See also Figures 1 to 4 . 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.

[0026] 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.

[0027] For this example, please refer to Figure 1 The utility model provides an embodiment of a dressing demoulding device, which is used to separate a dressing sheet from a dressing forming structure, and multiple forming structures are located on the same forming plate 3. The device includes a blow-out plate 4 with a cavity at the bottom, the cavity side wall is closed on three sides and one side is open, the forming plate 3 cooperates with the cavity and is inserted into it, and an air outlet duct 40 is arranged on the blow-out plate 4 on one side in contact with the forming plate 3, and the wind force blows the dressing sheet away from the forming structure, and the air outlet duct 40 is arranged on the side opposite to the opening of the cavity side wall.

[0028] In the above embodiment, the size of the bottom cavity of the device matches the molding plate 3, and the molding plate 3 can be inserted from one side of the cavity opening. Figure 3 As shown, after insertion, the forming cavity of the forming plate 3 is covered by the blow-out plate 4 of the device. Figure 4 As shown, Figure 4 Arrows are used to mark the gas flow direction. In the forming plate 3, the dressing sheet forming structure includes a filter screen. The dressing sheet is located above the filter screen. The gas blown in from the air duct 40 enters from the space below the filter screen, and then passes through the filter screen from bottom to top, blowing the dressing sheet off the filter screen, thereby solving the problem of the dressing sheet adhering to the filter screen. To facilitate the understanding of the above solution, the implementation of the matching forming plate 3 will be provided later.

[0029] For this example, please refer to Figure 2-4 The blowing plate 4 includes a base plate 41 and a sliding plate 42. The sliding plate 42 slides on the bottom of the base plate 41. The sliding plate 42 is connected to the base plate 41 through a first telescopic structure 43. When the sliding plate 42 is squeezed by the forming plate 3, it retracts and exposes the cavity. After the forming plate 3 is loaded into the cavity, the base plate 41 and the sliding plate 42 clamp the forming plate 3, and the end of the forming plate 3 is aligned with the air outlet duct 40 of the blowing plate 4.

[0030] In the above embodiment, the sliding plate 42 can automatically retract and pop up when the forming plate 3 is placed in the molded plate 3, so that when the wind blows into the molded plate 3 from the air duct 40, the air leakage can be reduced and the blowing effect can be improved. The sliding plate 42 and the base plate 41 form a sandwich structure to maintain the stability of the molded plate 3.

[0031] This embodiment can be found in Figure 1 and Figure 2 The blow-out plate 4 is provided with an air inlet 44, the blow-out plate 4 is hollow, and a plurality of sheet layers form an air outlet duct 40. The air inlet 44 allows the device to use an external wind source, and the sheet layer duct can make the wind more balanced and stable, ensuring that multiple molding stations on the molding plate 3 can receive wind.

[0032] Furthermore, a heating wire is arranged in the sheet layer of the air outlet duct 40. In this way, the air outlet duct 40 can blow out hot air, and the dressing sheet can be dried first with wind of relatively small force but slightly high temperature, and after the dressing sheet is dried to the target humidity, the dressing sheet can be blown away from the filter screen with strong wind and normal temperature wind.

[0033] For this example, please refer to Figure 1 and Figure 2 On the blow-out plate 4, on the side where the cavity opens, a sliding structure is provided at the end of the blow-out plate 4. The side where the cavity opens is also the side where the molding plate 3 is inserted. By providing the sliding structure, the insertion process can be guided, making the insertion smoother and facilitating the implementation of automated production.

[0034] Furthermore, the sliding structure is a smooth arc chamfer or a rolling shaft 46. The smooth arc chamfer structure is simple and can be integrally formed when manufacturing the blow-out plate 4; while the rolling shaft 46 has a better guiding effect. During the insertion of the forming plate 3, the forming plate 3 and the rolling shaft 46 on the blow-out plate 4 are in rolling contact, and the insertion is smoother.

[0035] In this embodiment, the first telescopic structure 43 is a spring, which contracts when squeezed and automatically recovers after the external force is withdrawn, with low cost and high reliability.

[0036] For this example, please refer to Figure 1 The blow-out plate 4 is mounted on the machine body through a first rod 47 and a second rod 48. One end of the first rod 47 is fixedly connected to the machine body, and the other end is rotatably connected to one side of the blow-out plate 4. One end of the second rod 48 is rotatably connected to the machine body, and the other end is rotatably connected to the other side of the blow-out plate 4. The length of the second rod 48 is adjustable.

[0037] In the above embodiment, the angle of the blow plate 4 can be adjusted. When implementing this solution, the angle of the blow plate 4 can be freely adjusted according to the on-site conditions, thereby facilitating the insertion of the forming plate 3 into its cavity and increasing the adaptability of the device to various production environments.

[0038] Furthermore, the second rod 48 is a telescopic cylinder, which can be controlled by an intelligent device to automatically adjust the angle of the blowing plate 4 to adapt to the insertion angle of the forming plate 3 in various scenarios.

[0039] To facilitate the understanding of the above scheme, the following is an embodiment of the forming plate 3 matched with the demoulding device:

[0040] For this example, please refer to Figure 5-6 , an embodiment of a molding plate 3 matched with the demoulding device, a molding structure is provided on the molding plate 3 for molding a dressing sheet, the molding structure includes an installation cavity 320 located on the molding plate and a molding box 321 matched with the installation cavity 320, a filter screen 323 is provided at the bottom of the molding box 321, and the top of the molding box 321 is open; bosses 3201 are provided on both sides of the installation cavity 320 and a drainage notch 3202 is provided at the outer end, and 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.

[0041] Furthermore, an auxiliary heating device 324 is installed in the installation cavity 320. The auxiliary heating device 324 is an electric heating wire or electric heating sheet attached to the bottom of the installation cavity 320. The filter screen 323 is detachably arranged at the bottom of the molding box 321. The filter screen 323 is detachably fixed to the bottom of the molding box 321 by magnetic attraction; the molding box 321 is detachably fixed in the installation cavity 320 by magnetic attraction.

[0042] On the side 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 from the filter screen by passing gas from the drainage notch 3202, and the gas can pass through the filter screen in the reverse direction, so as to achieve shedding.

[0043] On 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, during the movement process, especially when the dressing sheet needs to be separated from the filter screen and blown out, it is necessary to move the dressing sheet in a specific direction and exceed the baffle, so that the dressing sheet is not easily separated from the molding box in an unexpected direction due to the blowing wind force. In the above process, the baffle 3203 can prevent the dressing sheet from flying around and ensure that the dressing sheet always separates along the curved surface 3204.

[0044] In summary, the utility model effectively overcomes various shortcomings in the prior art, can produce beneficial technical effects, and has significant progress. The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the utility model should still be covered by the claims of the utility model.
