Description

Technical Field

[0001] This invention belongs to the technical field of dressing production equipment, and in particular relates to a dressing production and packaging device and method. Background Technology

[0002] Bio-cellulose membrane dressings can be roughly divided into wet and dry types. Among them, bio-cellulose wet membrane products require higher maintenance costs during transportation and storage due to their higher moisture content, while bio-cellulose dry membranes are lighter, thinner, more convenient, and easier to carry.

[0003] In the production process, the biocellulose membrane raw material needs to be broken down to obtain a biocellulose homogeneous material; the biocellulose homogeneous material is mixed with active ingredients to obtain a homogeneous mixture; the homogeneous mixture is laid on the filter element and dehydrated at room temperature and normal pressure to obtain a biocellulose wet membrane; finally, the biocellulose wet membrane is dried at a suitable temperature to obtain a biocellulose dry membrane dressing.

[0004] In related technologies, after obtaining the dressing, it needs to be immediately packaged to prevent the active ingredients from escaping and to prevent dust or bacteria from falling onto the dressing and causing contamination. However, in existing technologies, due to the special shape of the dressing, the transportation and packaging of the dressing requires a lot of manual intervention, which is not only inefficient but also prone to contamination.

This side is the feeding side. After the encapsulation film passes through the film inlet into the feeding frame, it passes through the film passage groove on the upper layer of the feeding frame to the other side of the feeding frame. This side is the reversing side. After being reversed through the "U"-shaped reversing groove, it passes back to the feeding side from the lower layer of the feeding frame.

[0015] Both the feeding side and the reversing side are equipped with a cutting mechanism that can cut the encapsulation film.

[0016] Optionally, the cutting mechanism includes a first power source and two cutting plates.

[0049] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0050] Please see Figures 1 to 15 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0051] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0052] Please refer to this embodiment. Figure 1-4 An embodiment of a dressing production and packaging apparatus provided by the present invention includes a forming part, a conveying part 6, a moving part 7, and a packaging part 8;

[0053] The forming section is used to continuously produce sheet-like dressings;

[0054] The conveying unit 6 receives the fabric sheet from the discharge side of the forming unit and transports it away from the forming unit;

[0055] The moving part 7 can move above the conveying part 6 to adjust its working position;

[0056] The packaging unit 8 includes a mounting platform 80, a feeding component 81, and a heat sealing component 82. The mounting platform 80 is fixedly connected to the moving part 7. The feeding component 81 and the heat sealing component 82 are both mounted on the mounting platform 80. The feeding component 81 puts the packaging film into the conveying part 6, and the heat sealing component 82 heat-seals the packaging film.

[0057] Among them, the forming part, such as Figure 2As shown, the assembly includes a raw material silo 1, a roller 2, a forming plate 3, and a discharge rail 5. The raw material silo 1 is used to contain homogeneous liquid raw materials, and the top of the raw material silo 1 is open. The roller 2 is rotatably disposed inside the raw material silo 1, and the roller 2 is arranged laterally with its circumferential side protruding from the opening of the raw material silo 1. Multiple forming plates 3 are arranged circumferentially on the circumferential side of the roller 2. One end of the forming plate 3 is connected to the roller 2 via a rotating hinge 30, and the other end is connected to the roller 2 via a telescopic mechanism 31. The tilt angle of the forming plate 3 relative to the roller 2 is variable. The forming plate 3 is provided with a forming structure 32 with an open top and a filter screen 323 at the bottom. The discharge rail 5 is disposed on one side of the opening of the raw material silo 1. One end of the discharge rail 5 extends into the raw material silo 1 and docks with the forming plate 3, and the other end extends out of the raw material silo 1 and docks with the conveying unit.

[0058] The molding structure 32 on the molding plate 3 can be referred to. Figure 14 The molding structure 32 includes an installation cavity 320 located in the molding plate 3 and a molding box 321 that mates with the installation cavity 320. A filter screen 323 is located at the bottom of the molding box 321, and the top of the molding box 321 is open. The installation cavity 320 has protrusions 3201 on both sides and a drainage notch 3202 at its outer end. After the molding box 321 is inserted into the installation cavity 320, a water outlet channel is formed at the bottom and a molding cavity is formed at the top. An auxiliary heating device 324 is installed in the installation cavity 320. 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 by an arc surface 3204. With the above design, by tilting the molding plate, the dressing sheet can automatically slide down along the arc surface 3204 and fall into the receiving conveying part. If the dressing sheet adheres to the filter screen in the forming box 321, air can be introduced through the blow-out plate 4 from the drainage gap 3202, passing in the opposite direction through the filter screen to blow the dressing sheet off the filter screen, thus achieving detachment. In the above process, a baffle 3203 can be set to prevent the dressing sheet from flying around due to wind force, thereby ensuring that the dressing sheet always detaches along the curved surface 3204.

[0059] The structure of the blow plate 4 can be found in [reference]. Figure 15 The installation location can be found in [reference]. Figure 2The blow-out plate 4 has a cavity at its bottom and is located above the open top of the raw material silo 1 and near the discharge rail 5. When the forming plate 3 rotates to the position of the blow-out plate 4, the bottom cavity of the blow-out plate 4 accommodates the forming plate 3, and the water outlet channel on the forming structure 32 is aligned and connected to the air outlet duct 40 of the blow-out plate 4. Specifically, the blow-out 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 and 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 inserted 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 blow-out plate 4. The blow-out plate 4 has an air inlet 44. The plate body of the blow-out plate 4 is hollow, and the air outlet duct 40 is formed by multiple sheet-like layers. The air inlet 44 allows the device to use an external air source. By utilizing the automatic retraction and ejection function of the sliding plate 42, when the molding plate 3 is inserted, the sliding plate 42 can block the bottom surface of the molding plate 3. In this way, when the wind blows into the molding plate 3 from the air duct 40, the air leakage can be reduced and the blowing effect can be improved.

[0060] In the above embodiments, the simplified working process of the forming section continuously producing sheet dressings is as follows:

[0061] The homogeneous liquid raw material mixture is filled into the raw material silo 1. The filling amount should not be too large to prevent the liquid raw material from being spilled out by the forming plate 3 during the rotation of the roller 2. The homogeneous liquid raw material mixture contains bio-fibers, which are filamentous products metabolized through microbial fermentation and culture, exhibiting a 3D three-dimensional interwoven fiber structure. High-speed grinding of the bio-fibers yields a homogeneous bio-fiber mixture. This homogeneous bio-fiber mixture is then mixed with active ingredients to obtain the homogeneous liquid raw material mixture.

[0062] The initial installation angle of the molding plate 3 on the roller 2 should be appropriate. Since one end of the molding plate 3 is connected to the roller 2 via a rotating hinge 30 and the other end is connected to the roller 2 via a telescopic mechanism 31, the initial angle of the molding plate 3 on the roller 2 can be adjusted by adjusting the initial telescopic amount of the telescopic mechanism 31. The smaller the initial angle, the smaller the projected area of ​​the molding plate 3 and the liquid raw material during the rotation of the roller 2, and the smaller the mutual resistance. The quantity and thickness distribution of the bio-fibers filtered and retained on the molding plate 3 will also be different, which can be adjusted according to the actual needs of the dressing sheets to be produced.

[0063] It is possible Figure 2 As shown, the roller 2 is eccentrically installed inside the raw material silo 1. Figure 2 On the left side, the forming plate 3 is squeezed by the inner wall of the raw material hopper 1, causing the telescopic mechanism 31 to retract. Therefore, the forming plate 3 on this side is almost in contact with the surface of the drum 2, and has almost no filtering effect on the bio-fibers. Once the drum 2 rotates past the bottom, as... Figure 2As shown on the right, the forming plate 3 will open according to the initial extension length of the telescopic mechanism 31, and begin to filter and retain biological fibers.

[0064] Roller 2 continues to rotate, and once the forming plate 3 leaves the liquid surface, as... Figure 2 When the material is positioned at the upper right side, the bio-fibers retained on the forming plate 3 can begin to be dried. Drying is carried out by the auxiliary heating device 324 in the mounting cavity 320. To achieve the desired drying effect, the rotation of the drum 2 can be temporarily stopped. After a suitable drying time, the drum 2 resumes rotation. When it reaches the position shown in the image... Figure 2 When the middle left upper part is in the middle, the tilt angle of the molding plate 3 increases, and the dry dressing sheet in the molding plate 3 automatically slides into the discharge rail 5 and falls into the conveying part 6 for packaging and transportation away from the production area.

[0065] If the dressing sheet adheres to the filter 323 on the molding plate 3, then it can be as follows: Figure 2 When the state shown is reached, air is supplied to the air outlet duct 40 on the blower plate 4. The air enters the bottom of the filter screen 323 from the drain opening 3202 and then passes through the filter screen 323 in the opposite direction. This blows the dressing away from the state of being stuck to the filter screen 323 and allows it to slide off automatically along the curved surface 3204 under the action of the air.

[0066] In the above embodiments, after the dressing sheet is formed, the main working process of the packaging process is as follows:

[0067] First, the unloading assembly 81 of the packaging section 8 places a plastic film at the starting end of the conveyor belt of the conveyor section 6. Then, the dressing sheet to be packaged is placed onto the plastic film mechanically or manually. When using machinery, as in the above embodiment, the dressing sheet produced by the forming section automatically falls along the discharge rail 5 onto the plastic film at the starting end of the conveyor belt. Then, the unloading assembly 81 of the packaging section 8 places another plastic film in the original position to cover the original plastic film and the dressing sheet to be packaged. Finally, the heat sealing assembly 82 of the packaging section 8 presses the two layers of plastic film around the perimeter and uses high temperature to fuse the two layers of plastic film together to form a seal. The above packaging process is completed by mechanical automation, which can reduce the amount of manual intervention, improve the packaging efficiency and quality of the dressing sheet, and adapt to automated production.

[0068] Please refer to this embodiment. Figure 3-8 Specifically, the unloading assembly 81 includes a feeding mechanism 810 and an unloading frame 811;

[0069] The feeding mechanism 810 includes two parallel extruders 8101. The encapsulation film passes through the two extruders 8101 and, after gaining power, enters the unloading frame 811.

[0070] The feeding frame 811 is vertically slidably sleeved on the outer periphery of the mounting platform 80. The feeding frame 811 is provided with a film inlet 8110 on the side near the feeding mechanism 810. This side is the feeding side. After the encapsulation film passes through the film inlet 8110 into the feeding frame 811, it passes through the film passage groove 8111 on the upper layer of the feeding frame 811 to the other side of the feeding frame 811. This side is the reversing side. After being reversed through the "U"-shaped reversing groove 8112, it passes back to the feeding side from the lower layer of the feeding frame 811.

[0071] Both the feeding side and the reversing side are equipped with a cutting mechanism 812, which can cut the encapsulation film.

[0072] In the above embodiment, the working principle is as follows: A plastic film with appropriate hardness is inserted into the feeding mechanism 810. The rolling and squeezing action of the feeding mechanism 810 forces the plastic film into the unloading frame 811, and it automatically moves according to the guide groove provided in the unloading frame 811. Figure 4 As shown, after the plastic film reaches one side, it is reversed via the reversing groove and flows back to the feeding side. At this time, the cutting mechanism on the reversing side cuts the encapsulation film, and the encapsulation film located in the lower layer of the unloading frame 811 automatically falls onto the conveyor belt. Then the entire unloading device is removed, and other machinery or manpower are used to put the encapsulated items onto the encapsulation film on the conveyor belt, or the dressing sheet produced by the forming part is automatically dropped onto the encapsulation film along the discharge rail 5. Then, the film-feeding device returns to the top of the encapsulation film, aligning it with the original encapsulation film position. The cutting mechanism on the feeding side then cuts the encapsulation film in the guide groove. Since this encapsulation film remains within the film-passing groove 8111 on the upper layer of the feeding frame 811, it will not fall off automatically. However, because the feeding frame 811 is a frame structure, the encapsulation film can be pushed out of the guide groove within the feeding frame 811 simply by lowering the mounting platform 80 or raising the feeding frame 811. After this encapsulation film detaches from the feeding frame, it covers the original encapsulation film. Then, the hot-melt device contacts the edges of both encapsulation films, completing the encapsulation of both films. The above device enables automated film feeding, simplifying and increasing the efficiency of the plastic film feeding and cutting process, while reducing contact and contamination of the encapsulated object.

[0073] Furthermore, the cutting mechanism 812 includes a first power source 8121 and a cutting plate 8122. The two cutting plates 8122 are vertically slidably installed on the feeding side and the reversing side, respectively. The cutting plate 8122 passes through the unloading frame 811 into the film groove 8111 and contacts the encapsulation film. The vertical movement distance of the cutting plate 8122 is controlled by the first power source 8121.

[0074] In the above embodiments, the cutting mechanism 812 can be controlled by an electrical signal, thereby enabling the entire device to operate automatically according to the production rhythm of the production line.

[0075] Furthermore, the contact surface between the cutting plate 8122 and the encapsulation film is either a blade or a heating wire. Using a heating wire results in better cutting and requires less cutting pressure. The extruder 8101 can be a cylindrical roller. Alternatively, the extruder 8101 can be two sets of parallel friction belts driven by the rollers. Besides generating greater friction between the plastic film and the extruder, the friction belts also have a flattening effect, making the originally rolled plastic film flatter and facilitating the subsequent encapsulation process. A material rack 803 can also be installed on the feeding side of the mounting platform 80, with a shaft on which the encapsulation film roll is fitted. The encapsulation film roll moves together with the film-laying device, reducing the path of the encapsulation film and increasing the working range of the film-laying device, thus adapting to multi-station operation.

[0076] The vertical sliding distance of the feeding frame 811 is controlled by the feeding power source. When the feeding frame 811 slides into the mounting platform 80, the mounting platform can push out the upper layer of the encapsulation film of the feeding frame 811. If it cannot slide, after placing the lower layer of encapsulation film and placing the object to be encapsulated on the encapsulation film, it is necessary to continue feeding the encapsulation film, allowing it to move along the lower layer, cover the object to be encapsulated, and then cut the lower layer of encapsulation film again to encapsulate. This method can easily cause the object to be encapsulated to be pushed during the feeding process of the lower layer of encapsulation film, resulting in poor encapsulation. The first power source 8121 is a magnetic suction telescopic mechanism. The characteristic of this structure is that it reacts quickly and can complete the action instantly when the power is turned on and off, pulling the cutting plate 8122 to move and cut the encapsulation film. The first power source 8121 includes a magnetic housing and a spindle. The outer end of the spindle is fixedly connected to the cutting plate 8122, and the other end is slidably connected inside the magnetic housing. When energized, the spindle retracts; when de-energized, the spindle pops out. The automatic pop-out of the spindle is achieved by an internally installed spring. In case of system failure, the spindle is in the pop-out state to avoid malfunction. The cutting operation can also be achieved by manually pressing the cutting plate 8122 to overcome the spring force. Multiple first power sources 8121 can be installed along the cutting plate 8122. The length of the cutting plate 8122 matches the width of the plastic film. Installing multiple first power sources 8121 at intervals ensures the smooth operation of the cutting plate 8122 and prevents uneven force along the width of the plastic film, which could lead to incomplete cutting.

[0077] Please refer to this embodiment. Figure 9-10 The heat-sealing assembly 82 includes a second power source 821 and a heat-sealing frame 822;

[0078] The heat-sealing frame 822 is vertically slidably fitted around the outer periphery of the mounting platform 80. A heat-melting assembly is provided on the lower side of the heat-sealing frame 822. The vertical movement distance of the heat-sealing frame 822 along the mounting platform 80 is controlled by the second power source 821.

[0079] In the above embodiments, during encapsulation, the mounting platform first moves down to press down on the perimeter of the plastic film. Then, the second power source drives the heat-sealing frame to move down and contact the plastic film. The heat-melting components on the heat-sealing frame heat up, fusing the two layers of plastic film together, thereby achieving encapsulation. This device automates the encapsulation process, simplifies manual operation, and improves encapsulation quality.

[0080] Furthermore, the mounting platform 80 is a rectangular frame structure with an open bottom, and a venting notch 801 is provided on one side of the bottom of the mounting platform 80. Inside the mounting platform 80, there is a shapeless extruder 802 that can press down on the sealing film. When the mounting platform 80 presses down on the plastic film, the plastic film can be pressed down from the inside of the rectangular frame structure, allowing air between the two layers of plastic film to escape, preventing bulging during sealing, reducing the amount of air trapped inside the plastic film, and improving the sealing and preservation effect. The extruder 82 inside the mounting platform 80 squeezes the plastic film and expels air. The shapeless extruder 82 can adapt to the shape of the object being sealed inside the plastic film, achieving a better gas venting effect. The specially designed venting notch 801 on one side also improves the smoothness of gas venting.

[0081] Furthermore, the extrusion component 802 is a flexible bag filled with sand or liquid. The sand and liquid have a high density, but their shape is not fixed. After the mounting platform 80 presses down on the plastic film, the flexible bag also presses down on the inside of the plastic film accordingly, and automatically adapts to the shape of the object being packaged inside the plastic film, automatically expelling excess gas, so that the packaging film adheres tightly to the packaged object, while the packaged object is not crushed.

[0082] The extrusion member 82 is slidably mounted within the rectangular frame of the mounting platform 80. In this embodiment, initially, only the mounting platform 80 presses down on the perimeter of the plastic film, and then the extrusion member 82 moves down to press down on the upper surface of the plastic film. This method provides better gas expulsion. In addition to allowing the sand or gas inside the flexible bag to squeeze the plastic film and expel the gas due to its own gravity, it also provides additional pressure, allowing the plastic film used for sealing to adhere more tightly to the object being sealed. The extrusion member 82 can also be a flexible bag that can be filled with gas and expand. The purpose of filling with gas is also to cause the flexible bag to expand and deform, squeezing the plastic film. Compared to the method of filling with fluid and heavy objects, the pressure gas method in this embodiment provides controllable squeezing force, better squeezing effect, and wider applicability.

[0083] Furthermore, the outer layer of the hot melt assembly 8221 can be ceramic or metal, and an internal heating wire is provided. Ceramic or metal has high temperature resistance and good durability. The hot melt assembly 8221 is installed on the underside of the heat-sealing frame 822 via a heat insulation layer 8222. The heat insulation layer 8222 can prevent heat from being conducted from the hot melt assembly 8221 to the frame, thereby reducing heat loss and preventing heat conduction from affecting other components. A temperature sensor is installed on the hot melt assembly 8221. The temperature of the part in contact with the plastic film can be monitored in real time, thereby adjusting the hot melt temperature for different types of plastic films with different packaging requirements, improving the hot melt effect, and preventing damage to the plastic film due to loose sealing or over-heat melting.

[0084] This embodiment can be referred to. Figure 1-2 The molding section has multiple production stations, and the conveying section 6 has multiple conveying channels. The moving section 7 can be found in [reference needed]. Figure 11-13 It includes a front-to-back moving mechanism, a horizontal moving mechanism, and a lifting moving mechanism. The front-to-back direction refers to the transport direction of the dressing sheet. The front-to-back moving mechanism is fixedly installed on the frame. The horizontal moving mechanism is slidably installed on the front-to-back moving mechanism. The lifting moving mechanism is slidably installed on the horizontal moving mechanism. The encapsulation part 8 is fixedly installed on the bottom of the lifting moving mechanism.

[0085] In the above embodiments, the encapsulation unit is installed above the dressing sheet conveying unit in sequence via a lifting and moving mechanism, a horizontal moving mechanism, and a front-to-back moving mechanism. Therefore, the encapsulation unit can move back and forth or left and right along the transport direction of the transport rail and lift and lower to encapsulate the dressing sheet at a specific position on a specific transport rail. This avoids setting up an encapsulation unit above each transport rail, which significantly reduces production costs and improves the utilization rate of the encapsulation unit.

[0086] For reference, see the forward and backward moving mechanism. Figure 11-13The system includes parallel front and rear lead screws 721 and front and rear guide rods 722. One end of the horizontal moving mechanism is slidably engaged with the front and rear guide rods 722, and the other end is threadedly engaged with the front and rear lead screws 721. The front and rear lead screws 721 drive the horizontal moving mechanism to move along the front and rear guide rods 722. The front and rear guide rods 722 include a guide rod body 7221 and a guide rod housing 7222. The guide rod housing 7222 is fixedly installed on the frame, and the guide rod body 7221 is installed inside the guide rod housing 7222. A moving groove 7223 is opened on the inner side of the guide rod housing 7222. One end of the horizontal moving mechanism passes through the moving groove 7223 and is slidably connected between the guide rod body 7221 and the guide rod housing 7222. The lead screw 721 includes a lead screw body and a lead screw housing. The lead screw housing is fixedly installed on the frame, and the lead screw body is installed inside the lead screw housing. Both ends of the lead screw body are rotatably connected to the lead screw housing and can be driven by a power source. A moving groove 7223 is also opened on one side of the lead screw housing. One end of the horizontal moving mechanism passes through the moving groove 7223 and is threadedly connected to the lead screw body on the inner side, and slidably engaged with the lead screw housing on the outer side. The horizontal moving mechanism includes a horizontal lead screw 71, a horizontal guide rod 72, and a horizontal nut 73. One side of the lifting moving mechanism is slidably connected to the horizontal guide rod 72, and a nut seat is provided on the other side of the lifting moving mechanism. Both ends of the horizontal nut 73 are rotatably installed in the nut seat. At the same time, the horizontal lead screw 71 and the horizontal nut 73 are threadedly engaged. When the horizontal nut 73 rotates, it drives the lifting moving mechanism to slide along the horizontal guide rod 72. The horizontal nut 73 is driven by a power source provided on the lifting moving mechanism. In this embodiment, the position of the power source and the position of the horizontal nut 73 are relatively fixed. The power source moves with the horizontal nut 73 and drives the horizontal nut 73, which simplifies the complexity of the transmission structure. The horizontal nut 73 and the power source driving the horizontal nut 73 are connected by a transmission belt or transmission chain. The horizontal lead screw 71 and the horizontal guide rod 72 are enclosed by a horizontal telescopic bladder 74. The lifting and moving mechanism includes an upper plate 730 and a lower plate 732. The upper plate 730 is mounted on the horizontal moving mechanism, and the lower plate 732 is equipped with the encapsulation part 8. The upper plate 730 and the lower plate 732 are connected by a lifting mechanism, and a telescopic bladder can also be provided on the outer layer for protection.

[0087] This embodiment is an example of a dressing production and packaging method provided by the present invention, which uses the above-mentioned dressing production and packaging device and includes the following steps:

[0088] Raw material preparation: The bio-cellulose membrane raw material is crushed to obtain a bio-cellulose homogenate, and the bio-cellulose homogenate is mixed with the active ingredient to obtain a homogeneous mixture liquid;

[0089] Dressing production: The forming section shapes, dehydrates, and dries the homogeneous liquid mixture into dressing sheets;

[0090] Placing the bottom film: The feeding assembly 81 places the first encapsulation film at the beginning of the conveying section 6;

[0091] Placing the dressing sheet: The dried dressing sheet is fed into the conveying section 6 and placed on the first encapsulation film. In order to ensure that the dressing sheet can be accurately placed in the middle area of ​​the first encapsulation film, an auxiliary guiding mechanism can be set up so that the conveying section 6 is located at the discharge end of the forming section. The conveying section receives the dressing sheet falling from the conveying section. In specific implementation, the positions and angles between them are adjusted to ensure that the dressing sheet always falls exactly into the middle area of ​​the first encapsulation film.

[0092] Placing the upper film: The feeding assembly 81 places the second encapsulation film and covers the dressing sheet and the first encapsulation film;

[0093] Encapsulation dressing: The heat sealing component 82 heat seals the outer peripheries of the first and second encapsulation films by heat sealing at high temperature.

[0094] Some detailed steps of the above-described encapsulation method were also described in the preceding section on the accompanying device, and can be understood in conjunction with these steps. The combination of the above device and method enables automated encapsulation of dressing sheets, improving the encapsulation efficiency and quality of the dressing sheets.

[0095] In summary, the present invention effectively overcomes the various shortcomings of the prior art, produces beneficial technical effects, and has made significant progress.

[0096] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can 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 those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
