Description

Technical Field

[0001] This invention relates to the field of bonding equipment technology for biological protective fabrics, specifically a bonding process for a nanofiber membrane biological protective fabric. Background Technology

[0002] Nanofiber membrane bioprotective fabric is a type of fabric with highly efficient protective functions made from nanofiber membranes. It is mainly used to protect the human body from harmful substances such as microorganisms, viruses, and bacteria. This fabric is commonly used to make protective products such as masks, protective clothing, and medical bandages. During the production process, nanofiber membrane bioprotective fabric requires bonding equipment to adhere the nanofiber membrane to non-woven fabrics or other textiles.

[0003] According to Chinese Patent Application No. 202010641231.6, a special composite fabric and its production equipment are disclosed, relating to the field of composite fabric production equipment. The equipment includes a workbench, with a feeding component at one end and a transfer roller at the top. Support legs are located at the bottom of the workbench. An adhesive application component is located at the end of the transfer roller near the feeding component, and a first pressing component is located at the end away from the adhesive application component. A second electric push rod, a connecting frame, a second pressing roller, and a second fixing frame are configured. The composite fabric moves to the area below the second pressing component. The second electric push rod is controlled to move, causing it to drive four second pressing rollers to move laterally back and forth on the composite fabric via the connecting frame. Simultaneously, the four second pressing rollers rotate via the second fixing frame, thus performing secondary pressing on the composite fabric, resulting in more uniform pressing and effectively solving the problem of uneven fabric pressing.

[0004] The above case effectively solves the problem of uneven bonding that easily occurs during the pressing process in existing bonding equipment. It has the advantage of being able to press the fabric evenly. However, when bonding, a rubber roller is required to apply adhesive. The rotation of the rubber roller causes the adhesive to adhere to the surface of the roller and then be applied to the fabric. However, the amount of adhesive on the rubber roller will vary, resulting in uneven application of adhesive to the fabric, which in turn affects the bonding of the fabric. Summary of the Invention

[0005] The purpose of this invention is to provide a bonding process for bioprotective fabrics made of nanofiber membranes, which has the advantage of enabling uniform adhesive application by the adhesive roller. This solves the problem that the amount of adhesive on the adhesive roller may vary, resulting in uneven application of adhesive to the fabric and thus affecting the bonding of the fabric.

Both ends of the first and second pressure rollers are movably connected to the support plate via bearings. One side of the guide rail is fixedly connected to the support frame. One side of the slider is fixedly connected to the support plate. The other side of the slider extends into the inner cavity of the guide rail and is slidably connected to the guide rail. The output end of the first cylinder is fixedly connected to the support plate.

[0010] Preferably, the transmission assembly includes a motor, a driving wheel, a driven wheel, a first gear, and a second gear.

[0015] Preferably, the bonding process includes the following steps:

[0016] A. First, add adhesive to the inner cavity of the material tank, and then adjust the bonding position of the bonding component by adjusting the component. The output end of the first cylinder extends and retracts to push the support plate and drive the guide rail to move downward along the surface of the slider. When the support plate moves, it drives the first pressure roller and the second pressure roller to move downward, so that the second pressure roller is close to the anilox roller.

[0017] B. Next, adjust the position of the scraping component so that it can scrape the adhesive applied to the fabric surface. The output end of the second cylinder extends and pushes the mounting plate upward, so that the mounting plate can drive the blade holder upward. Rotate the threaded rod, which rotates along the inner cavity of the threaded block and pushes the blade holder closer to the anilox roller, thereby adjusting the position of the scraper.

[0018] C. Then, the fabric and nanofiber membrane are unwound by the unwinding machine. The fabric first contacts the surface of the anilox roller. The output shaft of the motor rotates, which drives the drive wheel to rotate. When the drive wheel rotates, it drives the driven wheel to rotate via the belt. When the driven wheel rotates, it drives the first gear to rotate. When the first gear rotates, it drives the second gear to rotate.

Then, the fabric passes through the scraping component. The scraper can scrape the adhesive applied to the surface of the fabric to make it evenly coated.

[0019] D. Then the fabric and the nanofiber membrane simultaneously enter between the second pressure roller and the first pressure roller. The first guide roller can guide them, and the second pressure roller and the first pressure roller can press the nanofiber membrane and the fabric together to bond them. The bonded fabric enters the inner cavity of the shell and comes into contact with the surface of the cooling roller. The fan and the cooling roller can cool the bonded fabric so that the adhesive can cure quickly.

[0020] E. Finally, the fabric is guided by the second guide roller and cut through the chute. The support roller can provide support for the fabric during the cutting process. The cut fabric is then wound up by the take-up roller. The output end of the third cylinder extends and retracts to push the movable plate to one side, so that the take-up roller can fall off the top of the movable plate for easy unloading.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention, by setting up a bonding mechanism, an unwinding machine, a cooling component, and a winding mechanism, achieves the effect of bonding fabric.

[0042] Example 3

[0043] Reference Figure 2-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] In this embodiment, the leveling assembly 16 includes a support rod 161, a connecting plate 162, a second cylinder 163, a mounting plate 164, a tool holder 165, a scraper 166, a threaded block 167, and a threaded rod 168.

[0045] The cooling assembly 3 includes a housing 301, a cooling roller 302, and a fan 303. The cooling roller 302 is installed in the inner cavity of the housing 301, and the fan 303 is installed on the top of the housing 301.

[0046] The dividing assembly 41 includes a second guide roller 411, a chute 412, a cutter 413, and a support roller 414. The second guide roller 411, the chute 412, the cutter 413, and the support roller 414 are all installed on one side of the inner cavity of the frame 40. The second guide roller 411 is used to guide the fabric, the cutter 413 is used to support the chute 412, the chute 412 is used to cut the fabric, and the support roller 414 is used to support the fabric.

[0047] The winding assembly 42 includes a movable plate 421, a third cylinder 422, and a winding roller 423. One end of the third cylinder 422 is movably connected to the inner wall of the frame 40 via a bearing, and the output end of the third cylinder 422 is movably connected to the movable plate 421 via a bearing. The winding roller 423 is mounted on the upper end of the third cylinder 422 and is movably connected to the third cylinder 422 via a bearing.

[0048] like Figure 2-5 As shown, the position of the scraping component 16 is adjusted so that it can scrape the adhesive applied to the fabric surface. The output end of the second cylinder 163 extends and pushes the mounting plate 164 upward, so that the mounting plate 164 can drive the blade holder 165 upward. The threaded rod 168 rotates along the inner cavity of the threaded block 167 and pushes the blade holder 165 closer to the anilox roller 132, thereby adjusting the position of the scraper 166. The finished fabric enters the inner cavity of the housing 301 and meets the cooling roller 302. The surface contact fan 303 and cooling roller 302 can cool the bonded fabric, allowing the adhesive to cure quickly. Finally, the fabric is guided by the second guide roller 411 and cut through the chute 412. The support roller 414 can provide support for the fabric during cutting. The cut fabric is then wound up by the take-up roller 423. The output end of the third cylinder 422 extends and retracts to push the movable plate 421 to one side, allowing the take-up roller 423 to fall off the top of the movable plate 421 for easy unloading. Cooling water can be added to the inner cavity of the cooling roller 302.

[0049] like Figure 1-5 As shown, the bonding process of the present invention includes the following steps:

[0050] A. First, add adhesive to the inner cavity of the material tank 131. Then, adjust the bonding position of the bonding component 12 by adjusting the component 14. The output end of the first cylinder 141 extends and retracts to push the support plate 142, which drives the guide rail 143 to move downward along the surface of the slider 144. When the support plate 142 moves, it drives the first pressure roller 121 and the second pressure roller 122 to move downward, so that the second pressure roller 122 is close to the anilox roller 132.

[0051] B. Next, adjust the position of the scraping component 16 so that the scraping component 16 can scrape the adhesive applied to the fabric surface. The output end of the second cylinder 163 extends and pushes the mounting plate 164 upward, so that the mounting plate 164 can drive the blade holder 165 upward. Rotate the threaded rod 168. The threaded rod 168 rotates along the inner cavity of the threaded block 167 and pushes the blade holder 165 closer to the anilox roller 132, thereby adjusting the position of the scraper 166.

[0052] C. Then, the fabric and nanofiber membrane are unwound by the unwinding machine 2. The fabric first contacts the surface of the anilox roller 132. The output shaft of the motor 151 rotates, driving the drive wheel 152 to rotate. When the drive wheel 152 rotates, it drives the driven wheel 153 to rotate via the belt. When the driven wheel 153 rotates, it drives the first gear 154 to rotate. When the first gear 154 rotates, it drives the second gear 155 to rotate. When the second gear 155 rotates, it drives the anilox roller 132 to rotate, so that the anilox roller 132 can apply the adhesive to the surface of the fabric. Then, the fabric passes through the scraping component 16. The scraper 166 can scrape the adhesive applied to the surface of the fabric to make it evenly coated.

[0053] D. Then the fabric and the nanofiber membrane simultaneously enter between the second pressure roller 122 and the first pressure roller 121. The first guide roller 123 can guide them. The second pressure roller 122 and the first pressure roller 121 can press the nanofiber membrane and the fabric together to bond them. The bonded fabric enters the inner cavity of the outer shell 301 and comes into contact with the surface of the cooling roller 302. The fan 303 and the cooling roller 302 can cool the bonded fabric so that the adhesive can cure quickly.

[0054] E. Finally, the fabric is guided by the second guide roller 411 and cut by the chute 412. The support roller 414 can provide support for the fabric during the cutting process. The cut fabric is then wound up by the take-up roller 423. The output end of the third cylinder 422 extends and retracts to push the movable plate 421 to one side, so that the take-up roller 423 can fall off the top of the movable plate 421 for easy unloading.

7. The bonding process of a nanofiber membrane bioprotective fabric according to claim 6, characterized in that: The bonding process includes the following steps: A. First, add adhesive to the inner cavity of the material tank (131), and then adjust the bonding position of the bonding component (12) by adjusting the component (14). The output end of the first cylinder (141) extends and retracts to push the support plate (142) to drive the guide rail (143) to move downward along the surface of the slider (144). When the support plate (142) moves, it drives the first pressure roller (121) and the second pressure roller (122) to move downward, so that the second pressure roller (122) is close to the anilox roller (132). B. Next, adjust the position of the scraping component (16) so that the scraping component (16) can scrape the adhesive applied to the fabric surface. The output end of the second cylinder (163) extends and pushes the mounting plate (164) upward, so that the mounting plate (164) can drive the knife holder (165) upward. Rotate the threaded rod (168), and the threaded rod (168) rotates along the inner cavity of the threaded block (167) and pushes the knife holder (165) closer to the anilox roller (132), thereby adjusting the position of the scraper (166). C. Then, the fabric and nanofiber membrane are unwound by the unwinding machine (2). The fabric first contacts the surface of the anilox roller (132). The output shaft of the motor (151) rotates, driving the drive wheel (152) to rotate. When the drive wheel (152) rotates, it drives the driven wheel (153) to rotate via the belt. When the driven wheel (153) rotates, it drives the first gear (154) to rotate. When the first gear (154) rotates, it drives the second gear (155) to rotate. When the second gear (155) rotates, it drives the anilox roller (132) to rotate, so that the anilox roller (132) can apply the adhesive to the surface of the fabric. Then, the fabric passes through the scraping component (16). The scraper (166) can scrape the adhesive applied to the surface of the fabric to make it evenly coated. D. Then the fabric and the nanofiber membrane simultaneously enter between the second pressure roller (122) and the first pressure roller (121). The first guide roller (123) can guide them. The second pressure roller (122) and the first pressure roller (121) can press the nanofiber membrane and the fabric together to bond them. The bonded fabric enters the inner cavity of the outer shell (301) and contacts the surface of the cooling roller (302). The fan (303) and the cooling roller (302) can cool the bonded fabric so that the adhesive can be cured quickly. E. Finally, the fabric is guided by the second guide roller (411) and cut through the chute (412). The support roller (414) can provide support for the fabric during cutting. The cut fabric is wound up by the take-up roller (423). The output end of the third cylinder (422) extends and retracts to push the movable plate (421) to one side, so that the take-up roller (423) can fall off the top of the movable plate (421) for easy unloading.
