[0002] Due to its unique structure and properties, non-woven fabrics have a wide range of applications in the fields of medical, health, industry, agriculture, etc. However, traditional non-woven fabrics may not possess certain specific functions, such as antibacterial, flame-retardant, waterproof, etc., which to a certain extent limits their application in some high-end fields. In order to expand the application scope of non-woven fabrics and improve their added value, researchers have developed a series of hydrophilic modification technologies aimed at improving the water absorption, air permeability, flame retardancy, antibacterial properties, etc. of non-woven fabrics.

[0003] However, in the process of implementing related technical solutions, it is found that there are at least the following technical problems: Non-woven fabrics are generally modified by impregnating with surface activators. During impregnation, the non-woven fabric is generally directly contacted with the surface activator, which easily leads to uneven impregnation of the fabric body, making the surface activator unable to fully penetrate into the non-woven fabric, thus affecting the subsequent operations of the non-woven fabric and resulting in poor performance of the non-woven fabric. Summary of the Utility Model

[0004] This application solves the problem of uneven impregnation of non-woven fabrics in the prior art by providing a device for surface modification treatment of medical non-woven fabrics, and realizes the effect of fully infiltrating the surface activator into the non-woven fabric.

At the top and bottom inside the pool body, a plurality of second tension rollers are arranged. The plurality of second tension rollers are arranged at equal intervals and staggered inside the pool body. A non-woven fabric is arranged between the two first tension rollers and the plurality of second tension rollers. A pressing mechanism is arranged on one side of the first tension roller at the bottom. The pressing mechanism includes: a connecting seat movably connected to one side of the first tension roller at the bottom; an elastic block fixedly arranged on one side of the connecting seat, and the elastic block is in contact connection with the non-woven fabric on the side of the first tension roller at the bottom.

[0006] Further, a fixing seat is arranged at the bottom outside the pool body. An activity plate is slidably connected inside the fixing seat.

Detailed implementation manners

[0017] The embodiment of the present application discloses a device for surface modification treatment of medical non-woven fabric. By rotating the reciprocating lead screw 651 to drive the elastic block 64 to press the non-woven fabric 30 reciprocally, the surfactant can fully penetrate into the interior of the non-woven fabric 30, improving the impregnation effect.

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0019] Please refer to Figure 1 and Figure 2 , this embodiment provides a device for surface modification treatment of medical non-woven fabric, including a tank body 10. A surface activator is arranged inside the tank body 10. Through grooves 20 are opened at the tops of both sides of the tank body 10. A winding mechanism is arranged outside the tank body 10. At the top and bottom of one side inside the tank body 10, first tension rollers 40 are fixedly arranged. The two first tension rollers 40 are in the same vertical plane. A plurality of second tension rollers 50 are arranged at the top and bottom inside the tank body 10. The plurality of second tension rollers 50 are arranged at equal intervals and staggered inside the tank body 10. A non-woven fabric 30 is arranged between the two first tension rollers 40 and the plurality of second tension rollers 50. The non-woven fabric 30 enters the tank body 10 through a through groove 20 at the top of the tank body 10, passes through the two first tension rollers 40 and the plurality of second tension rollers 50, and then extends out through the through groove 20 on the other side. The winding mechanism drives the non-woven fabric 30 to move inside the tank body 10, so that the non-woven fabric 30 can be wound after being impregnated inside the tank body 10. By arranging the first tension rollers 40 and the second tension rollers 50 at the top and bottom, the non-woven fabric 30 can be bent inside the tank body 10, increasing the impregnation area and time of the non-woven fabric 30 inside the tank body 10 and improving the impregnation effect.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3, a pressing mechanism 60 is provided on one side of the first tensioning roller 40 at the bottom, and a fixing seat 80 is provided at the bottom outside the pool body 10. The pressing mechanism 60 includes: a movable plate 61, a plug rod 62, a connecting seat 63, an elastic block 64, and a reciprocating assembly 65. The movable plate 61 is slidably connected to the inside of the fixing seat 80. A plurality of plug rods 62 are inserted and connected to the bottom of the pool body 10. One end of each of the plurality of plug rods 62 is fixedly connected to the movable plate 61. The connecting seat 63 is fixedly provided at one end of the plurality of plug rods 62. The connecting seat 63 is slidably connected to one side of the first tensioning roller 40 at the bottom. The elastic block 64 is fixedly provided on one side of the connecting seat 63, and the elastic block 64 is in contact connection with the non-woven fabric 30 on the side of the first tensioning roller 40 at the bottom. The elastic block 64 has a certain elastic force, so that the elastic block 64 will not damage the first tensioning roller 40 when reciprocally pressing the non-woven fabric 30. The reciprocating assembly 65 is provided on the side of the movable plate 61 away from the pool body 10. The reciprocating assembly 65 includes a reciprocating lead screw 651, a movable sleeve 652, and a reduction motor 653. The reciprocating lead screw 651 is rotatably connected to the inside of the fixing seat 80. The movable sleeve 652 is sleeved and threadedly connected to the outside of the reciprocating lead screw 651, and one end of the movable sleeve 652 is fixedly connected to the movable plate 61. The reduction motor 653 is fixedly installed inside the fixing seat 80, and the output shaft of the reduction motor 653 is fixedly connected to the reciprocating lead screw 651. By driving the rotation of the reciprocating lead screw 651 by the reduction motor 653, the reciprocating lead screw 651 drives the movable sleeve 652 threadedly connected to the outside thereof to reciprocate. The insertion connection of the plurality of plug rods 62 and the pool body 10 makes the movable plate 61 and the movable sleeve 652 not rotate with the reciprocating lead screw 651, so that the movable sleeve 652 can drive the movable plate 61 to reciprocate. The movable plate 61 drives the elastic block 64 on the connecting seat 63 to reciprocate, so that the elastic block 64 reciprocally collides with the non-woven fabric 30 on one side of the first tensioning roller 40 at the bottom. The elastic block 64 presses the surface activator against the non-woven fabric 30, so that the surface activator penetrates into the gaps of the non-woven fabric 30 and completely immerses into the inside of the non-woven fabric 30, making the impregnation effect of the non-woven fabric 30 better.

[0021] Please refer to Figures 1-4, a scraping component 70 is arranged inside the through groove 20 on the side of the pool body 10 away from the first tensioning roller 40. The scraping component 70 includes a movable rod 71, a scraping plate 72, and a spring 73. The movable rod 71 is inserted and connected inside the through groove 20. The scraping plate 72 is fixedly arranged at the bottom of the movable rod 71, and the bottom of the scraping plate 72 is in contact connection with the through groove 20. An activity groove 90 is opened at the top of the through groove 20 where the scraping plate 72 is located. The scraping plate 72 is slidably connected inside the activity groove 90. The spring 73 is arranged inside the activity groove 90. Two ends of the spring 73 are respectively fixedly connected with the inner wall of the activity groove 90 and the movable rod 71. Due to the elastic force of the spring 73, the scraping plate 72 has a tendency to move downward, pressing the non-woven fabric 30 downward tightly. Cooperating with the winding mechanism to drive the movement of the non-woven fabric 30, when the non-woven fabric 30 is moved out of the pool body 10, the scraping plate 72 and the inner wall of the bottom of the through groove 20 can scrape off the impregnating liquid adhered to the surface of the non-woven fabric 30, facilitating the subsequent cleaning of the non-woven fabric 30 and preventing the impregnating liquid from affecting the subsequent processing of the non-woven fabric 30.

[0022] The functional principle of the present application can be elaborated through the following operation modes:

[0023] During use, the non-woven fabric 30 extends into the pool body 10 from the through groove 20 on the side of the pool body 10 close to the first tensioning roller 40, then passes through the two first tensioning rollers 40 and multiple second tensioning rollers 50, and then extends out of the pool body 10 from the through groove 20 on the other side of the pool body 10. The winding mechanism drives the movement of the non-woven fabric 30, so that the non-woven fabric 30 can be fully impregnated in the activator on the inner surface of the pool body 10 to complete the modification treatment. The folding and bending of the non-woven fabric 30 between the two first tensioning rollers 40 and multiple second tensioning rollers 50 can increase the impregnation area and time, thereby improving the impregnation effect. Start the reduction motor 653 inside the fixed seat 80, so that the output shaft of the reduction motor 653 drives the reciprocating lead screw 651 to rotate, so that the movable sleeve 652 threadedly connected therewith drives the movable plate 61 to reciprocate, so that the elastic block 64 on one side of the connecting seat 63 repeatedly presses the non-woven fabric 30 on one side of the bottom first tensioning roller 40, pressing the surface activator towards the non-woven fabric 30 on one side of the first tensioning roller 40, so that the surface activator can more comprehensively penetrate into the non-woven fabric 30, thereby improving the modification treatment effect. The elastic force of the spring 73 inside the activity groove 90 makes the movable rod 71 and the scraping plate 72 have a tendency to move downward, so that the scraping plate 72 presses the non-woven fabric 30 tightly at the top of the non-woven fabric 30 in the through groove 20. The top and bottom of the non-woven fabric 30 extending out of the pool body 10 are pressed tightly against the scraping plate 72 and the inner wall of the through groove 20, so that the impregnating liquid on the surface of the non-woven fabric 30 can be scraped off, facilitating the subsequent cleaning of the non-woven fabric 30 and preventing the influence of the surface activator on the subsequent processing.
