Description

Technical Field

[0001] The present invention relates to the field of antibacterial fabrics, in particular to an antibacterial fabric and a method for preparing the same. Background Art

[0002] Antimicrobial fabrics refer to functional fabrics that have been treated with special processes to inhibit or kill microorganisms such as bacteria and fungi. They are widely used in the fields of medicine, hygiene, clothing, etc. At present, the preparation of antimicrobial fabrics generally adopts the post-finishing method, that is, the antimicrobial agent is applied to the surface of the fabric through dipping, coating, spraying, etc. to form an antimicrobial layer. This method is simple and low-cost, and is applicable to various natural and synthetic fibers. Among them, when using the dipping method, the fabric is generally immersed in the antimicrobial solution, and the antimicrobial solution is fully infiltrated into the fabric before the fabric is dried. However, at present, most of the dipping and drying operations are completed by combining dipping equipment and drying equipment, and it is impossible to complete the dipping and drying operations with only one preparation device. Summary of the Invention

[0003] The purpose of the present invention is to provide an antibacterial fabric preparation device and method, which can complete padding and drying.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] An antibacterial fabric preparation device includes a storage box for containing antibacterial liquid and a center frame for guiding the fabric below the antibacterial liquid level. The center frame includes a central tube with two ends respectively penetrating the two side surfaces of the storage box and rotating. The outer surface of the central tube is evenly fixed with support arms around the circumference. Each support arm is connected to the central tube, so that air can enter the support arms from both ends of the central tube and be blown out from the outer ends of the support arms, thereby blowing the fabric surrounded by the central frame away from the central end, blowing the antibacterial liquid through the fabric located in the antibacterial liquid, and drying the fabric that has left the antibacterial liquid.

[0006] Each support arm comprises two air pipes connected and fixed with the central pipe, and ends of the two air pipes, which are away from the central pipe, are connected and fixed with an open box which is parallel to the central pipe.

[0007] Both edges of each open box for supporting fabric are provided with convex edges.

[0008] End wheels are fixed at both ends of the central tube, and joint pipes I are rotated at the centers of the outer ends of the two end wheels. A transmission shaft is rotated on the storage box, and the transmission shaft is connected to the two end wheels.

[0009] A leakage hole is provided at the bottom of each open box, and a fixed plate is fixed between the two air pipes connected to the same open box, and a sliding plate is also passed through. A spring is provided between the fixed plate and the sliding plate to allow the blocking plate on the sliding plate to be inserted into the leakage hole. Pins are fixed at both ends of each sliding plate, and fixing rings are coaxially fixed to the inner walls on both sides of the corresponding central tube of the sorting box. Guide blocks are fixed to the inner rings of the two fixing rings. When the support arm rotates to the two guide blocks, the two guide blocks squeeze the two pins to open the leakage hole and discharge the antibacterial liquid in the open box.

[0010] There are rotating side plates rotating on the two fixed rings, and a horizontal axis I rotates between the two rotating side plates. A horizontal frame is provided laterally on the upper end of the storage box, and a circular cavity tube is provided in the horizontal frame. A plurality of ventilation holes are evenly provided on the circular cavity tube. Both ends of the circular cavity tube pass through the horizontal frame and are fixed with square seats. The two square seats pass through the outer ends of the storage box and are fixed with joint tube II.

[0011] A screw rod is fixed at the middle of the horizontal frame, a threaded sleeve is connected to the screw rod through a thread, and the threaded sleeve is rotatably connected to the storage box.

[0012] A horizontal axis II rotates in the horizontal frame away from the screw end, and a linkage plate rotates at both ends between horizontal axis II and horizontal axis I. A horizontal axis III rotates just above horizontal axis II in the horizontal frame, and an introduction roller rotates laterally at the upper end of the sorting box.

[0031] like Figure 1-9 As shown, the antibacterial fabric preparation device is described in detail:

[0032] A device for preparing antibacterial fabrics includes a storage box 101 for containing antibacterial liquid, and a center frame for guiding fabrics below the antibacterial liquid level. The center frame includes a rotating center tube 201 with both ends respectively penetrating the two side surfaces of the storage box 101. The outer surface of the center tube 201 is evenly fixed with support arms circumferentially, and each support arm is connected to the center tube 201, so that air can enter the support arms from both ends of the center tube 201 and be blown out from the outer ends of the support arms, thereby blowing air onto the fabric surrounded by the center frame away from the center end, blowing the antibacterial liquid through the fabric located in the antibacterial liquid, and simultaneously drying the fabric that has been separated from the antibacterial liquid.

[0033] During preparation, the prepared antibacterial liquid is first added into the sorting box 101; then the fabric to be sorted is introduced from the upper end of the sorting box 101, and is led out from the upper end of the sorting box 101 after passing through the center frame; at the same time, the fabric is tightened so that the fabric is wrapped around the center frame. At this time, the fabric below the center frame is immersed in the antibacterial liquid at the same time, and then the fabric is pulled backward so that the fabric continuously enters the sorting box 101 and passes through the center frame. When the fabric passes through the center frame, compressed gas is introduced from both ends of the center tube 201, and then The liquid enters multiple support arms at the same time from the inner cavity of the central tube 201 and is blown out from the outer ends of the support arms. The support arms located below will blow the antibacterial liquid flowing between the support arms and the fabric, so that the antibacterial liquid passes through the fabric, thereby ensuring that the antibacterial liquid can fully soak the fabric. At the same time, the support arms located above will blow toward the fabric separated from the antibacterial liquid, thereby accelerating the air flow at the wet fabric, thereby drying the fabric, and directly winding and collecting the fabric; thereby, the device can achieve the purpose of completing impregnation and drying.

[0034] The compressed gas can be a high-temperature gas of 40-70°C, so as to achieve a better drying effect on the fabric;

[0035] The antibacterial liquid may be a nanosilver antibacterial liquid comprising, by weight, 0.1%-0.5% nanosilver, 0.5%-1% polyvinyl pyrrolidone (PVP), 5%-8% propylene glycol, 10%-15% ethanol, 0.1%-0.3% citric acid, and the remainder, deionized water. Other antibacterial liquids known in the art may also be selected as needed.

[0036] Further:

[0037] Each support arm includes two air pipes 204 connected and fixed to the central pipe 201 . The ends of the two air pipes 204 away from the central pipe 201 are connected and fixed to an open box 206 parallel to the central pipe 201 .

[0038] The air pipe 204 is provided to support the end of the open box 206 extending away from the central tube 201, while also connecting the central tube 201 with the open box 206, thereby facilitating air flow from the central tube 201 into the open box 206 and out through the open end of the open box 206.

[0039] The open end of the open box 206 is away from the center tube 201 and is also the end in contact with the fabric. Due to the existence of the inner cavity of the open box 206, when the open box 206 is located in the antibacterial liquid below, the antibacterial liquid will flow into the inner cavity of the open box 206. Then, when air enters the inner cavity of the open box 206 through the air pipe 204, it will blow the antibacterial liquid in the inner cavity toward the open end, and then pass through the fabric, so that the antibacterial liquid fully infiltrates the fabric.

[0040] It should be noted that there are multiple support arms, which are evenly arranged, so there are also multiple support arms located below and in the antibacterial liquid. Therefore, when the fabric moves continuously, it will pass through the open boxes 206 of multiple support arms, thereby further ensuring that the antibacterial liquid can fully infiltrate the fabric.

[0041] Further:

[0042] Each of the open boxes 206 is provided with convex edges 207 on both edges for supporting the fabric.

[0043] Through the setting of the two convex edges 207, when the fabric is wrapped around the open end of the open box 206, the open end completes the contact with the fabric through the two convex edges 207, and then a gap is formed between the fabric and the left and right sides of the open end of the open box 206, through which the antibacterial liquid can flow into the open box 206, thereby forming a supplement of the antibacterial liquid to the open box 206 on both sides, ensuring that there is sufficient antibacterial liquid in the open box 206 and keeping the antibacterial liquid fully infiltrating the fabric.

[0044] Further:

[0045] End wheels 202 are fixed at both ends of the central tube 201 , and joint tubes I 203 are rotated at the centers of the outer ends of the two end wheels 202 . A transmission shaft 105 is rotated on the storage box 101 , and the transmission shaft 105 is in transmission connection with the two end wheels 202 .

[0046] Through the first motor installed on the outside of the storage box 101, the first motor engages the worm gear on the transmission shaft 105 through the worm on the output shaft, thereby driving the transmission shaft 105, so that the transmission shaft 105 simultaneously drives the two end wheels 202, and then rotates the center tube 201 to form the rotation of the center frame, so that the multiple open boxes 206 will rotate in the storage box 101, thereby stirring the antibacterial liquid, thereby ensuring the uniformity of the antibacterial liquid, and through the rotation of the multiple open boxes 206, the fabric can be scraped, so that the liquid can penetrate into the gaps between the fabric fibers through mechanical force, while breaking the surface tension of the liquid to avoid local accumulation, and at the same time, the antibacterial liquid can be evenly adhered to the front and back sides of the fabric and the inside of the fibers; further, it is ensured that the antibacterial liquid can fully infiltrate the fabric.

[0047] Among them, the rotation setting of the joint pipe I 203 facilitates connection with the air supply system and is not affected by the rotation of the end wheel 202, thereby facilitating the introduction of compressed air into the central pipe 201.

[0048] Further:

[0049] A leakage hole 208 is provided at the bottom of each open box 206, and a fixed plate 205 is fixed between the two air pipes 204 connected to the same open box 206, and a sliding plate 301 is sliding through it. A spring 303 is provided between the fixed plate 205 and the sliding plate 301, so that the blocking plate 302 on the sliding plate 301 is inserted into the leakage hole 208, and a pin 304 is fixed at both ends of each sliding plate 301. The inner walls of both sides of the storage box 101 corresponding to the central tube 201 are coaxially fixed with a fixing ring 103, and the inner rings of the two fixing rings 103 are fixed with a guide block 104. When the support arm rotates to the two guide blocks 104, the two guide blocks 104 squeeze the two pins 304, so that the leakage hole 208 opens to discharge the antibacterial liquid in the open box 206.

[0050] Under normal conditions, the spring 303 pushes the sliding plate 301 to slide on the two air tubes 204 and away from the central tube 201, pressing against the bottom of the open box 206. At this time, the blocking plate 302 on the sliding plate 301 is inserted into the leakage hole 208 to block the leakage hole 208, ensuring that the interior of the open box 206 is in a closed state except for the open end, so that the air entering the open box 206 can be blown out from the open end of the open box 206, or the antibacterial liquid can be blown out from the open end of the open box 206.

[0051] However, as the center frame rotates, the open box 206 will rotate around the center tube 201 as the axis, and then the open box 206 will sometimes be located in the antibacterial liquid and sometimes located on the antibacterial liquid surface. When the open box 206 rotates out of the antibacterial liquid, some antibacterial liquid will remain inside it. This part of the antibacterial liquid cannot be discharged and will always be blown by the air holes corresponding to the air pipe 204, splashing onto the fabric, thereby affecting the drying of the fabric.

[0052] The guide block 104 is set accordingly. When the open box 206 is about to separate from the antibacterial liquid, its corresponding two pin shafts 304 will contact the two guide blocks 104. Under the guidance of the two guide blocks 104, as the open box 206 continues to rotate, the two pin shafts 304 will drive the sliding plate 301 to approach the central tube 201, squeezing the spring 303 while causing the blocking plate 302 to slide out of the leakage hole 208, and then open the leakage hole 208. At this time, the open box 206 is in a tilted state, and the leakage hole 208 is located at the lowest point of the open box 206, thereby causing the antibacterial liquid stored in the open box 206 to automatically flow out. Until the two pin shafts 304 are separated from the two guide blocks 104, the antibacterial liquid stored in the open box 206 has been drained, and under the influence of the elastic force of the spring 303, the sliding plate 301 slides back, and the blocking plate 302 is inserted into the leakage hole 208 again to complete the blocking, thereby ensuring the air drying effect.

[0053] Among them, the two guide blocks 104 are symmetrically arranged and are arc-shaped, and the more the inner arc surface points upward, the closer it is to the center tube 201, thereby ensuring that as the opening box 206 rotates, the pin shaft 304 slides on the inner side surface of the guide block 104, so that the blocking plate 302 is farther away from the opening box 206, ensuring that the leakage hole 208 is fully opened.

[0054] Further:

[0055] A rotating side plate 401 is rotated on each of the two fixed rings 103, and a horizontal axis I 402 is rotated between the two rotating side plates 401. A horizontal frame 404 is horizontally provided at the upper end of the storage box 101, and a circular cavity tube 408 is provided in the horizontal frame 404. A plurality of ventilation holes 409 are evenly provided on the circular cavity tube 408. Both ends of the circular cavity tube 408 pass through the horizontal frame 404 and are fixed with square seats 405. The outer ends of the two square seats 405 pass through the storage box 101 and are fixed with joint tubes II 406.

[0056] A screw rod 411 is fixed to the middle of the horizontal frame 404 , and a threaded sleeve 412 is connected to the screw rod 411 through a thread, and the threaded sleeve 412 is rotatably connected to the storage box 101 .

[0057] A horizontal axis II 407 rotates in the horizontal frame 404 away from the end of the screw 411, and a linkage plate 403 rotates at both ends between the horizontal axis II 407 and the horizontal axis I 402. A horizontal axis III 410 rotates just above the horizontal axis II 407 in the horizontal frame 404, and an introduction roller 102 rotates laterally at the upper end of the storage box 101.

[0058] During use, the fabric enters the storage box 101 via the introduction roller 102, thereby preventing the fabric from contacting the edge of the side panel of the storage box 101 and causing wear to the fabric; then, the fabric is wrapped around the center frame, guided by the horizontal axis I 402, and separated from the center frame. After passing through the horizontal axis II 407, the fabric is wrapped around the circular cavity tube 408, and finally separated from the circular cavity tube 408 via the horizontal axis III 410, and completely separated from the device;

[0059] The horizontal axis I 402 is provided so that the position where the fabric is separated from the center frame can be as close as possible to the antibacterial liquid level on the fabric entry side, thereby maximizing the coverage of the center frame by the fabric, thereby ensuring the area for blowing air onto the fabric and thus ensuring the drying efficiency.

[0060] Through the cooperation of horizontal axis II 407 and horizontal axis III 410, the fabric can be wrapped on the circular cavity tube 408 after being dried by the central frame. Through two joint tubes II 406, it can be connected to the air supply system, and then the compressed gas is also introduced into the circular cavity tube 408, and then ejected simultaneously through multiple air holes 409, thereby blowing air on the fabric wrapped on the circular cavity tube 408, achieving the purpose of secondary drying, and further ensuring that the fabric separated from the device is in a dry state.

[0061] Among them, by rotating the threaded sleeve 412, the screw 411 can be threadedly driven to move axially therein, and then the horizontal frame 404 can move closer to or away from the inlet roller 102, thereby driving the two linkage plates 403 through the horizontal axis II 407, and the position of the horizontal axis I 402 can be adjusted, so that the horizontal axis I 402 drives the two rotating side plates 401 to rotate on the two fixed rings 103, so that the position of the horizontal axis I 402 can adapt to liquid levels of different heights, that is, the position where the fabric is separated from the center frame matches the liquid level height, ensuring the area for blowing air to the fabric as much as possible.

[0066] S3. When the fabric passes through the center frame, gas is introduced from both ends of the center tube 201 and blown out from the outer ends of the support arms, blowing the antibacterial liquid through the fabric in the antibacterial liquid and drying the fabric out of the antibacterial liquid, thereby directly obtaining dried antibacterial fabric.
