Abstract
Description
Technical Field
[0001] This application relates to the field of nonwoven fabric production technology, and in particular to a processing mechanism for antistatic, antibacterial, and hydrophilic nonwoven fabrics. Background Technology
[0002] Nonwoven fabric, also known as needle-punched cotton or needle-punched nonwoven fabric, is made from polyester fibers and is produced through a needle-punching process. This allows for the creation of various thicknesses, textures, and hardnesses. Nonwoven fabrics are characterized by moisture resistance, breathability, flexibility, lightness, flame retardancy, non-toxicity, odorlessness, low cost, and recyclability. They can be used in various industries, such as sound insulation, heat insulation, heating elements, masks, clothing, medical applications, and as filling materials.
[0003] Currently, nonwoven fabric production involves laying antibacterial and hydrophilic nonwoven fabrics flat with a nonwoven fabric substrate and bonding them together. The bonded nonwoven fabric is then placed into the next equipment for antistatic treatment.
[0004] Regarding the aforementioned technologies, the inventors believe that nonwoven fabrics are prone to delamination between the nonwoven fabric matrix and the antibacterial and hydrophilic nonwoven fabrics during use, causing the nonwoven fabrics to lose their antibacterial and hydrophilic effects. Utility Model Content
[0005] The purpose of this application is to provide a processing mechanism for antistatic, antibacterial, and hydrophilic nonwoven fabrics, so as to improve the problem that the nonwoven fabric matrix and the antibacterial and hydrophilic nonwoven fabrics are prone to delamination during use, causing the nonwoven fabric to lose its antibacterial and hydrophilic effects.
[0006] This application provides a processing mechanism for antistatic, antibacterial, and hydrophilic nonwoven fabrics, which adopts the following technical solution:
[0007] An antistatic, antibacterial, and hydrophilic nonwoven fabric processing mechanism includes a frame. A first roller carrying a nonwoven fabric base body is rotatably mounted at one end of the frame. Two laying components are sequentially arranged along the length of the frame. Each laying component includes a fixed frame connected to the frame. A third roller is rotatably mounted on the fixed frame. The third roller, located near the first roller, carries an antibacterial layer of nonwoven fabric bonded to the nonwoven fabric base body. The third roller, located away from the first roller, carries a hydrophilic layer of nonwoven fabric bonded to the nonwoven fabric. A second driving element is located at one end of the fixed frame near the third roller for rotating the third roller. A second roller for winding the nonwoven fabric is rotatably mounted at the end of the frame away from the first roller. A first driving element is located at one end of the frame near the second roller for rotating the second roller.
[0008] By adopting the above technical solution, a first roller and a second roller are respectively rotatably arranged at both ends of the frame. The non-woven fabric base body is wound on the first roller. Two laying components are arranged sequentially along the length of the frame. The antibacterial non-woven fabric layer is released from the third roller of the laying component closer to the first roller and bonded to the non-woven fabric base body. The hydrophilic non-woven fabric layer is released from the third roller of the laying component farther from the first roller and bonded to the connected non-woven fabric. This makes the connection between the antibacterial non-woven fabric layer, the hydrophilic non-woven fabric layer and the non-woven fabric base body tight, reducing the possibility of delamination between the three layers of non-woven fabric.
[0009] Optionally, the fixing frame is located below the roller three and has a rotating roller one that is in contact with the nonwoven base body. The antibacterial nonwoven layer and the hydrophilic nonwoven layer pass under the rotating roller one and are attached to the nonwoven base body.
[0010] By adopting the above technical solution, a rotating roller 1, which is rotatably connected to the nonwoven fabric base body via bearings and a rotating shaft below the fixed frame of the roller 3, is made to allow the antibacterial nonwoven fabric layer and the hydrophilic nonwoven fabric layer to pass under the rotating roller 1 and adhere to the nonwoven fabric base body. This reduces the possibility of gaps appearing between the antibacterial nonwoven fabric layer, the hydrophilic nonwoven fabric layer and the nonwoven fabric base body due to excessively long release sections of the antibacterial nonwoven fabric layer and the hydrophilic nonwoven fabric layer.
[0011] Optionally, the fixing frame is rotatably arranged below the nonwoven fabric base body, with a second rotating roller corresponding to the first rotating roller and abutting against the bottom of the nonwoven fabric base body.
[0012] By adopting the above technical solution, the fixed frame is located below the nonwoven base body and is rotatably connected to the second rotating roller. The second rotating roller corresponds to the first rotating roller and abuts against the bottom of the nonwoven base body, so that the second rotating roller together with the first rotating roller presses together the antibacterial nonwoven layer, the hydrophilic nonwoven layer and the nonwoven base body, so that the three layers of nonwoven fabric are tightly connected, reducing the possibility of delamination of the nonwoven fabric.
[0013] Optionally, the fixed frame has sliding grooves on the side walls at both ends of the rotating roller two. Fixed blocks that are slidably connected to the rotating roller two are rotatably connected in the sliding grooves. Sliding rods connected to the inner side walls of the sliding grooves are inserted on both sides of the rotating part of the rotating roller two. An elastic element is provided between the sliding rods and the inner side walls of the sliding grooves below the fixed blocks.
[0014] By adopting the above technical solution, a fixed block is slidably set in the slide groove opened in the fixed frame, and the fixed block is rotatably connected to the second rotating roller. Slide rods connected to the inner wall of the slide groove are inserted on both sides of the rotating part of the fixed block located on the second rotating roller. An elastic element is set between the fixed block and the inner wall of the slide groove. The fixed block and the second rotating roller are pushed upward by the reset of the elastic element, so that the second rotating roller abuts against the non-woven fabric base body, preventing gaps from appearing between the non-woven fabric base body and the second rotating roller when it moves from the first rotating roller to the second rotating roller, so that the second rotating roller cannot press the non-woven fabric together with the first rotating roller.
[0015] Optionally, the fixing frame is provided with a solvent nozzle located above the nonwoven base body and near the roller.
[0016] By adopting the above technical solution, sol particles are sprayed onto the nonwoven fabric from the sol nozzle, so that the nonwoven fabric is bonded when pressed by rotating roller one and rotating roller two, further reducing the possibility of delamination of the nonwoven fabric during use.
[0017] Optionally, a mounting frame is provided at one end of the frame near the second roller. The mounting frame is located above the nonwoven fabric and has a storage box containing antistatic coating. Below the storage box is a spray nozzle for spraying the antistatic layer onto the nonwoven fabric.
[0018] By adopting the above technical solution, a spray nozzle is set at the bottom of the storage box near the non-woven fabric. The spray nozzle is flush with the width of the non-woven fabric. An anti-static coating is sprayed onto the non-woven fabric through the spray nozzle to form an anti-static layer, thereby treating the non-woven fabric with anti-static properties.
[0019] Optionally, the frame is provided with a second mounting frame at one end of the mounting frame one near the second roller, and the second mounting frame is provided with drying plates on the upper and lower sides of the nonwoven fabric.
[0020] By adopting the above technical solution, drying plates are set on the upper and lower sides of the nonwoven fabric in the second mounting frame. The nonwoven fabric with the antistatic coating is heated and dried by the drying plates to prevent the nonwoven fabric from sticking when it is wound up by the second roller.
[0021] Optionally, the mounting frame two is rotatably mounted on the side of the drying plate near the roller two, with a rotating roller three that abuts against the upper and lower sides of the nonwoven fabric.
[0022] By adopting the above technical solution, a rotating roller three is rotatably connected to one end of the mounting frame two near the roller two, located on the upper and lower sides of the nonwoven fabric. The rotating roller three further presses the nonwoven fabric after the antistatic layer is sprayed, so that the layers of the nonwoven fabric after passing through the drying plate are tightly connected, further reducing the possibility of delamination of the nonwoven fabric during use.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The antibacterial layer nonwoven fabric and the hydrophilic layer nonwoven fabric are wrapped around the rotating roller and then attached to the nonwoven fabric base body. This reduces the possibility of gaps appearing between the antibacterial layer nonwoven fabric and the hydrophilic layer nonwoven fabric and the nonwoven fabric base body due to excessively long release sections.
[0025] 2. By resetting the elastic element, the fixed block and the second rotating roller are pushed upward along the slide groove, so that the second rotating roller abuts against the non-woven fabric base body, preventing gaps from appearing between the non-woven fabric base body and the second rotating roller when it moves from the first rotating roller to the second rotating roller, so that the second rotating roller cannot press the non-woven fabric together with the first rotating roller; sol particles are sprayed onto the non-woven fabric from the sol nozzle, so that the non-woven fabric is bonded when it is pressed by the first rotating roller and the second rotating roller, further reducing the possibility of delamination of the non-woven fabric during use;
[0026] 3. Drying plates are installed on the upper and lower sides of the nonwoven fabric in the second mounting frame. The drying plates heat and dry the nonwoven fabric with the antistatic layer to prevent the nonwoven fabric from sticking together when it is wound by the second roller. The nonwoven fabric with the antistatic layer is further pressed by the rotating roller three to make the layers of the nonwoven fabric after passing through the drying plate tightly connected, further reducing the possibility of delamination of the nonwoven fabric during use.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.
[0031] A processing mechanism for antistatic, antibacterial, and hydrophilic nonwoven fabrics, as described in the following article. Figure 1 and Figure 2The system includes a frame 1. A roller 11 is rotatably connected to one end of the frame 1 via bearings and a shaft. A non-woven fabric base body 2 is wound onto the roller 11. Two fixing frames 31 are welded along the length of the frame 1. These fixing frames 31 are rotatably connected to a roller 32 of the laying assembly 3 via bearings and a shaft. An antibacterial layer of non-woven fabric 4 is wound onto the roller 32 on the fixing frame 31 near the roller 11. The antibacterial layer of non-woven fabric 4 is made of graphene and non-woven fabric, effectively inhibiting bacterial growth and preventing bacterial growth due to moisture and prolonged use. A hydrophilic layer of non-woven fabric 5 is wound onto the roller 32 on the fixing frame 31 away from the roller 11. The hydrophilic layer of non-woven fabric 5 is made by spraying a hydrophilic agent onto the non-woven fabric, providing good hydrophilicity. Located below the third roller 32, a rotating roller 33 is rotatably connected to the nonwoven fabric base body 2 via bearings and a rotating shaft. The antibacterial nonwoven fabric 4 and the hydrophilic nonwoven fabric 5 pass under the rotating roller 33 and are sequentially bonded to the nonwoven fabric base body 2. A second driving component 34 is fixed to the fixed frame 31 with bolts. The second driving component 34 is a drive motor connected to the power supply to drive the third roller 32 to rotate and release the antibacterial nonwoven fabric 4 or the hydrophilic nonwoven fabric 5. At the end of the frame 1 away from the first roller 11, it is rotatably connected to the second roller 12 via bearings. At the end of the frame 1 located at the second roller 12, a first driving component 13 is fixed with bolts. The second driving component 34 is a drive motor connected to the power supply. The drive shaft of the drive motor is connected to the second roller 12 via a coupling to drive the second roller 12 to rotate and wind up the nonwoven fabric.
[0032] Reference Figure 2 A solvent nozzle 37 is sealed and connected to the fixed frame 31 above the nonwoven base body 2 and near the roller 11. The solvent nozzle 37 is connected to a storage tank containing solvent particles through a conveying pipe. By pressurizing the storage tank, the solvent nozzle 37 on the fixed frame 31 near the roller 11 sprays solvent particles onto the nonwoven base body 2. The antibacterial nonwoven fabric 4 is slowly released from the roller 32 near the roller 11 and bonded to the nonwoven base body 2 through the rotating roller 33. The solvent nozzle 37 on the fixed frame 31 located away from the roller 11 sprays solvent particles onto the antibacterial nonwoven fabric 4. The hydrophilic nonwoven fabric 5 is slowly released from the roller 32 away from the roller 11 and bonded to the nonwoven antibacterial nonwoven fabric 4 through the rotating roller 33.
[0033] Reference Figure 2The fixing frame 31 is located below the nonwoven fabric base body 2 and is rotatably connected to the rotating roller 35. The rotating roller 35 corresponds to the rotating roller 33 and abuts against the bottom of the nonwoven fabric base body 2. The fixing frame 31 has a sliding groove 311 on the side wall at both ends of the rotating roller 35. A metal fixing block 36 is slidably arranged in the sliding groove 311. The metal fixing block 36 and the rotating roller 35 are rotatably connected by bearings. Metal sliding rods 312 connected to the inner side wall of the sliding groove 311 are inserted on both sides of the rotating part of the fixing block 36 and the rotating roller 35. A spring as an elastic element 313 is installed between the fixing block 36 and the inner side wall of the sliding groove 311. The fixing block 36 and the rotating roller 35 are pushed upward by the spring reset, so that the rotating roller 35 abuts against the nonwoven fabric base body 2. The rotating roller 33 and the rotating roller 35 further press the nonwoven fabric after bonding, reducing the possibility of delamination of the nonwoven fabric during use.
[0034] Reference Figure 1 and Figure 2 At one end of the frame 1 near the second roller 12, a mounting frame 6 is bolted to it. Above the nonwoven fabric, a storage box 61 containing antistatic coating is installed on the mounting frame 6. Below the storage box 61, near the nonwoven fabric, a spray nozzle 62, flush with the width of the nonwoven fabric, is installed. The antistatic coating, made of synthetic materials such as polypropylene or polyester, is sprayed onto the nonwoven fabric through the spray nozzle 62 to form an antistatic layer. At one end of the frame 1 near the second roller 12, a mounting frame 7 is bolted to it. On the upper and lower sides of the nonwoven fabric, a drying plate 71 connected to a power source is bolted to the mounting frame 7. Heating resistance wires are installed in the drying plate 71 to dry the nonwoven fabric coated with the antistatic layer, preventing the nonwoven fabric from sticking together during winding. At one end of the mounting frame 7 near the second roller 12, a rotating roller 72 located on the upper and lower sides of the nonwoven fabric is rotatably connected via bearings. The rotating roller 72 further presses the nonwoven fabric, further reducing the possibility of delamination during use.
[0035] The implementation principle of this application embodiment is as follows:
[0036] The drive unit 13 starts driving the second roller 2 12 to begin winding the nonwoven fabric. Simultaneously, the drive unit 2 34 starts driving the third roller 32 to slowly release the antibacterial layer nonwoven fabric 4 and the hydrophilic layer nonwoven fabric 5. Sol-gel particles are sprayed onto the nonwoven fabric base body 2 from the solvent nozzle 37 near the first roller 11. The antibacterial layer nonwoven fabric 4 on the third roller 32 near the first roller 11 is bonded to the nonwoven fabric base body 2 under the rotating roller 1 33. The rotating roller 2 35, located below the nonwoven fabric base body 2, together with the rotating roller 1 33, presses the nonwoven fabric base body 2 and the antibacterial layer nonwoven fabric 4 together. Subsequently, the hydrophilic layer nonwoven fabric 5 on the third roller 32 away from the first roller 11 is bonded to the nonwoven fabric under the rotating roller 1 33. The rotating roller 35 below the nonwoven base body 2, together with the rotating roller 33, further presses the nonwoven fabric and the hydrophilic nonwoven fabric 5 together, bonding the antibacterial nonwoven fabric 4, the hydrophilic nonwoven fabric 5 and the nonwoven base body 2 together to prevent the nonwoven fabric from delaminating during use. An antistatic layer is evenly sprayed onto the nonwoven fabric from the spray nozzle 62, and the nonwoven fabric after spraying the antistatic layer is dried by the drying plates 71 on the upper and lower sides of the nonwoven fabric to prevent the nonwoven fabric from sticking together during winding. The rotating roller 72 located on the upper and lower sides of the nonwoven fabric further presses the nonwoven fabric together, further reducing the possibility of delamination between the nonwoven base body and the antibacterial and hydrophilic nonwoven fabrics during use, thus preventing the nonwoven fabric from failing.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
