Description

Technical Field

[0001] The present invention relates to the technical field of composite fabric production, and in particular to a device for producing a cool antibacterial composite nano protective fabric and a preparation method thereof. Background Art

[0002] As people's living standards improve, the functional requirements for clothing are also getting higher and higher. Especially during hot outdoor activities, people need clothing to have a cooling function to reduce skin temperature, and also need clothing to have antibacterial function to reduce the impact of outdoor bacteria on the skin. Existing outdoor clothing is mostly made of composite fabrics. Existing composite fabrics are made by gluing multiple single-layer fabrics together. The existing production method has the following disadvantages: uneven glue application, easy glue overflow after pressing the single-layer fabrics together, and water penetration at the seams of the composite fabrics.

[0003] Therefore, there is a need for a production device and a preparation method of a cool antibacterial composite nano protective fabric that can solve the above problems. Summary of the Invention

[0004] The present invention proposes a production device for a cool and antibacterial composite nano-protective fabric and a preparation method thereof. The fiber fabric strip is stretched and sprayed with a cool finishing agent through a spraying device, which greatly increases the coverage area of ​​the cool finishing agent on the fiber fabric strip, so that the finished clothing sewn from the fabric has better cool performance and durability. The solid first double-sided tape, second double-sided tape and film are used to avoid the occurrence of glue overflow. In conjunction with the cutting and transferring processes, the edges of the bonding edges on both sides of the film are sealed, which increases the sealing of the fabric bonding edges, thereby improving the waterproofness of outdoor wear.

Several expansion rollers for stretching the fiber fabric strip after the first spraying are arranged between the two first squeezing rollers and the two second squeezing rollers, and several of the expansion rollers are commonly connected to an expansion roller driving mechanism, and a second spray head for spraying the fiber fabric strip for a second time is arranged between two adjacent expansion rollers.

[0013] As a preferred technical solution, several of the expansion rollers are circumferentially distributed on the outside of the expansion roller driving mechanism, and several of the expansion rollers are all against the fiber fabric material strip between the two first liquid squeezing rollers and the two second liquid squeezing rollers. The expansion roller driving mechanism drives several of the expansion rollers to slide radially and be installed on the frame.

[0014] As a preferred technical solution, the expansion roller drive mechanism includes a driving screw rotatably mounted on the frame, a guide sleeve is sleeved on the driving screw, the guide sleeve is fixedly mounted on the frame, a sliding sleeve is slidably mounted on the outside of the guide sleeve, a nut is threadedly mounted on the driving screw, the nut is fixedly connected to the sliding sleeve, three sliding frames are slidably mounted on the frame along the radial direction of the sliding sleeve, the three sliding frames are circumferentially distributed on the outside of the sliding sleeve, two pairs of connecting rods are hinged between each sliding frame and the sliding sleeve, and three expansion rollers are provided and are rotatably mounted on the corresponding sliding frames.

[0015] As a preferred technical solution, a plurality of suction holes for adsorbing the antibacterial composite sheet are provided on the outer peripheral surface of the suction transfer roller, and a suction plate for connecting the suction holes and the vacuum pump is provided on one end shaft of the suction transfer roller. The suction plate is fixedly connected to the antibacterial material tape cutting and transfer knife seat, and a suction groove is provided on the suction plate.

[0016] As a preferred technical solution, the first cutting and laminating device includes a first double-sided tape cutting knife seat and a first double-sided tape laminating knife seat fixedly mounted on the frame, the first double-sided tape cutting knife seat is arranged upstream of the first double-sided tape laminating knife seat, and the first double-sided tape cutting knife seat is provided with a first double-sided tape traction mechanism and a first double-sided tape cutting mechanism.

[0017] As a preferred technical solution, the second cutting and laminating device includes a film laminating knife holder, a second double-sided tape laminating knife holder and a second double-sided tape cutting knife holder fixedly installed on the frame in sequence, the second double-sided tape cutting knife holder is provided with a second double-sided tape traction mechanism and a second double-sided tape cutting mechanism, and the second double-sided tape laminating knife holder is provided with a second double-sided tape pressing mechanism and a peeling mechanism.

[0018] As a preferred technical solution, the spray-pressing device also includes a drying box fixedly mounted on the frame, the drying box being arranged between the two second liquid squeezing rollers and the first cutting and laminating device, the drying box being connected to a hot air system, and the fiber fabric strip after impregnation passes through the drying box.

[0019] The preparation method of the cool antibacterial composite nano protective fabric production equipment specifically comprises the following steps:

[0020] S1, the fiber fabric strip passes through the spraying device and is sprayed twice;

[0021] S2, cutting the first double-sided tape by the first cutting and laminating device and laminating it to the top side of the fiber fabric strip after the second spraying;

[0022] S3, cutting the second double-sided tape by the second cutting and laminating device and laminating the antibacterial tape, the cut second double-sided tape, and the adhesive film together in sequence;

[0023] S4, the antibacterial material strip that completes step S3 passes between the antibacterial material strip cutting roller and the suction transfer roller, and the antibacterial material strip is cut into the antibacterial composite sheet. The cut antibacterial composite sheet is adsorbed on the suction transfer roller and rotates accordingly. At the same time, the fiber fabric strip that completes step S2 passes between the suction transfer roller and the antibacterial composite sheet laminating roller. When the antibacterial composite sheet passes through the antibacterial composite sheet laminating roller, the antibacterial composite sheet is laminated to the fiber fabric strip. After lamination, the adhesive film and the first double-sided tape are adhered together;

[0024] S5. After the fiber fabric strip is attached to the antibacterial composite sheet, it passes through the fiber fabric strip cutting knife seat and is cut into the required cool antibacterial composite nano protective fabric.

[0025] By adopting the above technical solution, the beneficial effects of the present invention are:

[0026] Since the production equipment for cool antibacterial composite nano-protective fabrics includes an antibacterial material strip cutting and transferring knife seat, during the use of this equipment, the spraying device stretches the fiber fabric strip and sprays it with a cool finishing agent. After spraying, the first cutting and laminating device cuts the first double-sided tape and laminates the cut first double-sided tape on the fiber fabric strip. The first double-sided tape seals the edges of the adhesive film and the fiber fabric strip in the cool antibacterial composite nano-protective fabric, thereby avoiding the occurrence of moisture penetration at the fabric seams.

[0027] The second double-sided tape is cut by the second cutting and laminating device, and the antibacterial material tape, the cut second double-sided tape and the adhesive film are laminated together in sequence. Then, the antibacterial material tape is cut into several antibacterial composite sheets by the antibacterial material tape cutting roller and the suction transfer roller and adsorbed on the suction transfer roller. As the suction transfer roller rotates, when the antibacterial composite sheet passes through the antibacterial composite sheet laminating roller, the antibacterial composite sheet is laminated to the material tape after two spraying operations, and then cut by the fiber fabric material tape cutting knife seat to complete the processing of the cool antibacterial composite nano protective fabric.

[0028] The present invention realizes the continuous cutting of antibacterial material strips into sheets through an antibacterial material strip cutting and transferring knife holder, and quickly and continuously realizes the transfer and bonding of antibacterial composite sheets, thereby improving the continuity of the antibacterial composite sheet cutting and bonding processes and improving the fabric processing efficiency. Compared with the existing single knife holder separate process processing, the fabric processing error caused by the installation error between the single knife holders is reduced, so that the first double-sided tape is accurately bonded to the edge of the first adhesive film, and the sealing of the finished fabric seam is further ensured.

[0029] The traditional processing technology of brushing glue takes a long time to brush glue, which greatly reduces the production efficiency of the fabric, and the brushing method is prone to glue overflow. The present invention adopts a solid first double-sided adhesive tape and a second double-sided adhesive tape to avoid the influence of brushing glue on the production efficiency of the fabric. In conjunction with the fast-rotating roller, the material strip can be quickly and continuously sprayed, pressed and cut. The first double-sided adhesive tape and the second double-sided adhesive tape respectively seal the edge of the bonding between the adhesive film and the fiber fabric material strip, and the edge of the bonding between the adhesive film and the antibacterial material strip, thereby improving the production efficiency of the fabric, avoiding the occurrence of glue overflow during fabric processing, and increasing the sealing of the fabric bonding edge, thereby improving the waterproofness of outdoor wear.

[0030] Since the production equipment of the cool antibacterial composite nano protective fabric includes a spraying device, in the process of spraying the fiber fabric strip, the first spray head sprays the fiber fabric strip for the first time, and after the first spraying, it passes between the two first squeezing rollers, and the excess cool finishing agent is squeezed out, and then it is wound on the expansion roller and passes between the two second squeezing rollers. The expansion roller is driven by the expansion roller driving mechanism, and the expansion roller stretches the fiber fabric strip. At the same time, the second spray head sprays the cool finishing agent onto the stretched fiber fabric strip. The present invention adopts a spraying method and stretches the fiber fabric strip through the expansion roller, so that the cool finishing agent can be fully impregnated into the fiber fabric strip, with high efficiency and better impregnation effect of the cool finishing agent, thereby improving the washability of the cool finishing agent, so that the finished clothing sewn from the fabric has better cooling performance and durability, and increases the comfort of people wearing outdoors in high temperatures.

[0031] Since the production equipment for cool and antibacterial composite nano-protective fabrics includes an expansion roller drive mechanism, during the second spraying process, since the nut is fixedly connected to the sliding sleeve, the sliding sleeve is axially slidably installed on the guide sleeve. As the driving screw rotates, the nut moves axially, causing the sliding sleeve to move axially. Under the connection and push of the connecting rod, the sliding frame moves radially. Under the pressure of the first squeezing roller and the second squeezing roller, the fiber fabric strip between the two first squeezing rollers and the two second squeezing rollers is pushed and stretched by the expansion roller, thereby increasing the fiber gap and allowing the cool finishing agent to be better impregnated into the fiber fabric strip.

[0032] Since the cool antibacterial composite nano-protective fabric production equipment includes an antibacterial material strip cutting and transfer knife seat, during the process of transferring the antibacterial composite sheet, as the suction transfer roller rotates, the suction hole will be disconnected or connected with the suction groove, thereby realizing the intermittent adsorption of the antibacterial composite sheet by the suction transfer roller, and then realizing the bonding of the antibacterial composite sheet from the suction transfer roller to the fiber fabric strip.

After the second spraying, the cooling finishing agent is fully impregnated into the fiber fabric strip 2, and a cooling layer 41 is formed on both sides of the fiber fabric strip 2.

[0091] S2. Cut the first double-sided tape 8 by a first cutting and laminating device and laminate it on the top side of the fiber fabric strip 2 that has been sprayed and dried twice.

[0092] During the process of cutting and laminating the first double-sided adhesive tape 8, after peeling off the first backing paper on both sides of the first double-sided adhesive tape 8, the first double-sided adhesive tape 8 and the first supporting film pass through the first double-sided adhesive cutting knife seat 27, and through two first double-sided adhesive traction rollers 38, the first supporting film is adhered to the bottom side of the first double-sided adhesive tape 8, and then through the first double-sided adhesive cutting knife roller 39 and the first double-sided adhesive cutting bottom roller 40, the first double-sided adhesive tape 8 is cut into a first double-sided adhesive frame 79 for sealing the edge between the fiber fabric strip 2 and the film 11, and then the first double-sided adhesive frame 79 is adhered to the top side of the fiber fabric strip 2 through the first double-sided adhesive laminating knife seat 28.

[0093] S3. Cut the second double-sided tape 9 by a second cutting and laminating device, and laminate the antibacterial tape 10, the cut second double-sided tape 9, and the adhesive film 11 together in sequence.

[0094] In the process of cutting the second double-sided tape 9 and laminating the antibacterial tape 10, the cut second double-sided tape 9 and the film 11 in sequence, after peeling off the second backing paper on both sides of the second double-sided tape 9, the second double-sided tape 9 and the second supporting film pass through the first double-sided tape cutting knife seat 27, and through two second double-sided tape pulling rollers 47, the second supporting film is adhered to the bottom side of the second double-sided tape 9, and then through the second double-sided tape cutting knife roller 48 and the second double-sided tape cutting bottom roller 49, the second double-sided tape 9 is cut into a second double-sided tape frame 80 for sealing the edge between the antibacterial layer and the film 11, and the second double-sided tape laminating knife seat 30 is used to laminarize the second double-sided tape frame 80 on the antibacterial tape 10, and then the film laminating knife seat 29 is used to laminarize the film 11 on the second double-sided tape frame 80.

The antibacterial material strip 10 is cut into antibacterial composite sheets 13. The cut antibacterial composite sheets 13 are adsorbed on the suction transfer roller 15 and rotate with it. At the same time, the fiber fabric material strip 2 that completes step S2 passes between the suction transfer roller 15 and the antibacterial composite sheet laminating roller 16. When the antibacterial composite sheet 13 passes through the antibacterial composite sheet laminating roller 16, the antibacterial composite sheet 13 is laminated on the fiber fabric material strip 2. After lamination, the adhesive film 11 is adhered to the first double-sided tape 8.

[0096] After the fiber fabric strip 2 passes between the two first backing film stripping rollers 45 , the first backing film is stripped from the fiber fabric strip 2 , and the first double-sided adhesive tape cutting waste is discharged together with the first backing film.

[0098] S5. After the fiber fabric strip 2 is attached to the antibacterial composite sheet 13, it passes through the fiber fabric strip cutting knife seat 17 and is cut into the required cool antibacterial composite nano protective fabric.

[0099] In summary, the present invention sprays the fiber fabric strip on both sides through a spraying device, so that the cooling finishing agent is fully impregnated into the fiber fabric strip, greatly improving the coverage area of ​​the cooling finishing agent on the fiber fabric strip, so that the finished clothing sewn from the fabric has better cooling performance and durability, and increases the comfort of people wearing it outdoors in high temperatures. The present invention adopts a solid first double-sided tape and a second double-sided tape, and cooperates with the cutting and transfer process to seal the edge of the bonding between the film and the antibacterial strip, and the edge of the bonding between the film and the fiber fabric strip, thereby avoiding the occurrence of glue overflow during fabric processing, increasing the sealing of the fabric bonding edge, and thus improving the waterproofness of outdoor wear.
