Description

Technical Field

[0001] This application relates to the field of fabric bonding technology, and in particular to a high-strength tear-resistant fabric structure and fabric bonding device. Background Technology

[0002] With the continuous advancement of outdoor sports and military equipment, higher demands are being placed on the strength and tear resistance of fabrics. Although traditional fabrics possess a certain degree of abrasion resistance and tear resistance, they are still prone to tearing and damage in extreme environments. Therefore, the textile industry typically employs methods that combine fabrics with various properties to improve the overall performance of the fabric.

[0003] In the relevant technical field, a common fabric bonding device has been designed, which typically includes a worktable and a glue spraying mechanism, a scraper, a compaction roller, and an unwinding roller mounted on the worktable. Two unwinding rollers are rotatably mounted on the worktable to unwind two different types of fabric. The fabric unwound by one unwinding roller passes sequentially through the glue spraying mechanism, the scraper, and the compaction roller. The glue spraying mechanism applies adhesive to the surface of the fabric, while the scraper spreads the adhesive evenly. After the adhesive is evenly spread, the fabric is layered with the fabric unwound by the other unwinding roller and together drawn into the compaction roller for a firm bond under high pressure.

[0004] In the process of developing this application, at least the following problems were found in this technology: After the squeegee spreads the adhesive evenly on the fabric surface, some adhesive remains on the squeegee surface. After the adhesive dries, it solidifies on the squeegee surface, affecting the flatness of the squeegee, which in turn affects the evenness of the adhesive spread on the fabric surface, and may even reduce the bonding effect of the fabric. Existing methods usually only perform a simple cleaning of the squeegee surface before the device is operated, but the cleaning effect is not ideal. Utility Model Content

[0005] To facilitate cleaning of the scraper, improve the uniformity of adhesive application, and ensure the bonding effect of the fabric, this application provides a high-strength tear-resistant fabric structure and a fabric bonding device.

[0006] The fabric bonding device provided in this application adopts the following technical solution: A fabric bonding device includes a worktable with a glue spraying mechanism, a scraper, a compaction roller, and an unwinding roller. A bracket is fixedly mounted on the worktable, and a rotating shaft is rotatably mounted on the bracket. One side of the scraper is fixedly connected to the rotating shaft. A slide rail is fixedly mounted on the bracket, with its length parallel to the length of the scraper. A cleaning block is slidably mounted within the slide rail, and a sliding assembly for driving the cleaning block to slide is provided within the slide rail. The cleaning block has a cleaning groove on its side facing the rotating shaft, extending through both sides of the cleaning block along the length of the scraper. A cleaning blade is mounted within the cleaning groove, and the other side of the scraper can extend into the cleaning groove and contact the cleaning blade.

[0007] By adopting the above technical solution, when the scraper needs to be cleaned, the rotating shaft drives the scraper to rotate, so that the side of the scraper in contact with the adhesive faces the slide rail. Then, the sliding assembly drives the cleaning block to slide along the slide rail, and the cleaning groove sleeve slides towards the scraper and continues to slide along the length of the scraper. During this process, the cleaning blade contacts the scraper and scrapes off the adhesive that has solidified on the scraper surface, ensuring the flatness of the scraper. This facilitates the cleaning of the scraper, improves the uniformity of adhesive application, and ensures the bonding effect of the fabric. When the cleaning block slides to the point where the cleaning groove separates from the scraper, the rotating shaft drives the scraper to rotate, so that the scraper returns to its original position where the adhesive is evenly applied.

[0008] Preferably, the sliding assembly includes a first motor and a lead screw, the lead screw rotates within the slide rail, the lead screw is threadedly engaged with the cleaning block, the first motor is fixed to the end of the slide rail, and the drive shaft of the first motor is coaxially fixed with the lead screw.

[0009] By adopting the above technical solution, after the first motor is started, the drive shaft of the first motor drives the lead screw to rotate. The lead screw engages with the cleaning block thread, and the cleaning block will move linearly along the axis of the lead screw. This makes it easier to control the moving speed of the cleaning block and ensures the stability of the cleaning process.

[0010] Preferably, a wiping cloth is fixedly installed in the cleaning groove, and the wiping cloth can contact the surface of the scraper.

[0011] By adopting the above technical solution, when the cleaning block moves, the wiping cloth will wipe the surface of the scraper synchronously with the cleaning blade, further removing residual adhesive and fine particles, making the scraper surface cleaner, thereby improving the quality of subsequent adhesive application.

[0012] Preferably, a waste box is detachably connected to the cleaning block, the waste box has an upward-facing receiving cavity, and the cleaning groove is located directly above the receiving cavity.

[0013] By adopting the above technical solution, the adhesive waste scraped off by the cleaning blade will fall directly into the receiving cavity below, making it easy to collect and process. At the same time, the detachable design of the waste box makes cleaning the adhesive waste inside the waste box more convenient; you only need to remove the waste box periodically to empty the waste.

[0014] Preferably, a snap ring is fixedly provided on the waste box, and a locking groove is provided on the cleaning block, into which the snap ring is inserted; a movable groove is provided on the side wall of the locking groove, and a movable block slides in the movable groove in the direction close to or away from the snap ring. A lock head is fixedly provided on the side of the movable block facing the snap ring, and the lock head extends into the snap ring and abuts against the snap ring.

[0015] By adopting the above technical solution, when the waste box needs to be installed, the snap ring is inserted into the locking groove, and the movable block is pushed to move towards the snap ring, so that the lock head is locked into the snap ring. The snap ring is fixed in the locking groove and cannot be disengaged, thus achieving a firm connection of the waste box. When disassembling, simply push the movable block in the opposite direction to disengage the lock head from the snap ring. At this time, the snap ring can be freely disengaged from the locking groove. The installation and disassembly of the waste box is simple and the connection is reliable.

[0016] Preferably, a thrust spring is provided between the end wall of the movable groove and the movable block. One end of the thrust spring is fixedly connected to the end wall of the movable groove, and the other end of the thrust spring is fixedly connected to the movable block. The thrust spring drives the movable block to approach the snap ring.

[0017] By adopting the above technical solution, the thrust spring always provides the moving block with a thrust toward the latching ring, ensuring that the lock head can be stably locked in the latching ring, preventing the waste box from loosening or falling off during operation, and ensuring the stability of waste collection.

[0018] Secondly, the high-strength tear-resistant fabric structure provided in this application adopts the following technical solution: applying a fabric bonding device, including a base fabric layer, a tear-resistant layer, and a cover layer, wherein the tear-resistant layer is located between the base fabric layer and the cover layer, the tear-resistant layer is hot-pressed onto the surface of the cover layer, and the base fabric layer and the tear-resistant layer are bonded together by the fabric bonding device.

[0019] By adopting the above technical solution, the base fabric layer and the tear-resistant layer are firmly bonded together by the fabric bonding device, which enhances the reliability of the bonding between the base fabric layer and the tear-resistant layer and is suitable for various fields with high requirements for strength and tear resistance.

[0020] Preferably, the tear-resistant layer is woven from aramid fibers.

[0021] By adopting the above technical solutions, aramid fibers not only have excellent tear resistance, but also have the characteristics of high temperature resistance, corrosion resistance, and light weight. When used as a tear-resistant layer in the fabric structure, it can significantly improve the strength of the fabric without adding too much weight, making the fabric lighter and more comfortable, thus meeting the needs of modern high-performance textiles.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a rotating shaft, slide rail, cleaning block, sliding assembly, cleaning groove, cleaning blade, and wiping cloth, when the scraper needs to clean, the rotating shaft drives the scraper to rotate and adjust the angle, the sliding assembly drives the cleaning block to move along the slide rail, the cleaning blade in the cleaning groove scrapes away the adhesive that has solidified on the scraper surface, and the wiping cloth further wipes away the residue, ensuring that the scraper surface is clean and flat, thereby improving the uniformity of subsequent scraper application of adhesive and ensuring the bonding effect of the fabric; 2. By setting a first motor and a lead screw, the first motor drives the lead screw to rotate, and the screw drive drives the cleaning block to slide stably, which makes it easy to control the moving speed of the cleaning block and ensures the stability of the cleaning process; 3. By setting up a waste box, a snap ring, a locking groove, a movable block, a lock head, and a thrust spring, the waste box is connected to the locking groove on the cleaning block through the snap ring. The movable block and the lock head securely lock the snap ring under the action of the thrust spring, ensuring that the waste box will not loosen or fall off during the waste collection process. At the same time, it is convenient to install and remove the waste box, and it is convenient for operators to clean the waste box regularly. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a fabric bonding device. (Refer to...) Figure 1 The apparatus includes a workbench 1, on which a glue spraying mechanism 12, a scraper 21, a compaction roller 13, and an unwinding roller 14 are mounted. Two unwinding rollers 14 rotate above the workbench 1, and are used to unwind different fabrics. The fabric unwound by one unwinding roller 14 passes sequentially through the unwinding roller 14 and the scraper 21, and is finally introduced into the compaction roller 13. The fabric unwound by the other unwinding roller 14 is directly introduced into the compaction roller 13. The glue spraying mechanism 12 sprays adhesive onto the surface of the passing fabric. The glue spraying mechanism 12 is a conventional method in the art and will not be described in detail here.

[0030] Reference Figure 1 The worktable 1 has supports 11 fixedly mounted on both sides, and a rotating shaft 2 is rotatably mounted on the supports 11. One side of a scraper 21 is fixedly connected to the rotating shaft 2, and the other side of the scraper 21 is used to spread the adhesive evenly on the surface of the fabric. A second motor 22 for driving the rotating shaft 2 is also fixedly mounted on the supports 11. The compaction roller 13 rotates on the worktable 1 to provide pressure for bonding the two fabrics. The two fabrics are pulled together and released from the unwinding roller 14. One fabric passes through the glue spraying mechanism 12 and is sprayed with adhesive on its surface. When passing through the scraper 21, the adhesive on the surface of the fabric is evenly spread by the scraper 21. Finally, the surfaces of the two fabrics are bonded together and fed into the compaction roller 13 together, where they are firmly bonded under high pressure.

[0031] Reference Figure 1 and Figure 2A slide rail 3 is fixedly mounted on the bracket 11. The length direction of the slide rail 3 is parallel to the length direction of the scraper 21, and the length of the slide rail 3 is greater than the length of the scraper 21. A cleaning block 31 is slidably mounted inside the slide rail 3, and a sliding component 32 for driving the cleaning block 31 to slide is provided inside the slide rail 3. A cleaning groove 311 is formed on the side of the cleaning block 31 facing the rotation axis 2. The cleaning groove 311 extends through both side walls of the cleaning block 31 along the length direction of the scraper 21. A cleaning blade 312 and a wiping cloth 313 are provided inside the cleaning groove 311. The other side of the scraper 21 can extend into the cleaning groove 311 and contact the cleaning blade 312 and the wiping cloth 313.

[0032] Reference Figure 1 and Figure 2 When the scraper 21 needs cleaning, the second motor 22 drives the rotating shaft 2 to rotate the scraper 21, so that the side of the scraper 21 in contact with the adhesive faces the slide rail 3. Then, the sliding assembly 32 drives the cleaning block 31 to slide along the slide rail 3, and the cleaning groove 311 fits onto the scraper 21 and continues to slide along the length of the scraper 21. During this process, the cleaning blade 312 first scrapes away the adhesive that has solidified on the surface of the scraper 21 to ensure the flatness of the scraper 21. Then, the wiping cloth 313 wipes the scraper 21 to remove residual adhesive and fine particles. This facilitates cleaning of the scraper 21, improves the uniformity of adhesive application, and ensures the bonding effect of the fabric.

[0033] Reference Figure 1 and Figure 2 The sliding assembly 32 includes a first motor 321 and a lead screw 322. The lead screw 322 rotates within the slide rail 3 and is threadedly engaged with the cleaning block 31. The first motor 321 is fixed to the end of the slide rail 3, and its drive shaft is coaxially fixed with the lead screw 322. In this embodiment, the first motor 321 is fixed on a bracket 11, and its drive shaft passes through the bracket 11 and is coaxially fixed with the lead screw 322. After the first motor 321 is started, its drive shaft drives the lead screw 322 to rotate, and the lead screw 322 engages with the cleaning block 31, causing the cleaning block 31 to move linearly along the axial direction of the lead screw 322.

[0034] To facilitate the collection of waste material scraped off the scraper 21 and ensure the cleanliness of the workbench 1 surface, refer to Figure 2 A waste box 4 is detachably connected to the cleaning block 31. The waste box 4 has an upward-facing receiving cavity 41, and the cleaning groove 311 is located directly above the receiving cavity 41.

[0035] For easy and quick installation or removal of waste box 4, refer to... Figure 2 and Figure 3A snap ring 42 is fixedly installed on the waste box 4, and a locking groove 33 is opened on the cleaning block 31. The snap ring 42 is inserted into the locking groove 33. A movable groove 331 is opened on the side wall of the locking groove 33. A movable block 332 slides in the movable groove 331 in the direction close to or away from the snap ring 42. A lock head 3321 is fixedly installed on the side of the movable block 332 facing the snap ring 42. The lock head 3321 extends into the snap ring 42 and abuts against the snap ring 42. A thrust spring 333 is provided between the end wall of the movable groove 331 and the movable block 332. One end of the thrust spring 333 is fixedly connected to the end wall of the movable groove 331, and the other end of the thrust spring 333 is fixedly connected to the movable block 332. The thrust spring 333 drives the movable block 332 to approach the snap ring 42.

[0036] Reference Figure 3 When the waste box 4 needs to be installed, move the movable block 332 away from the latching ring 42. The thrust spring 333 deforms, and then insert the latching ring 42 into the locking groove 33. Release the movable block 332, and the thrust spring 333 pushes the movable block 332 towards the latching ring 42, causing the lock head 3321 to engage with the latching ring 42. The latching ring 42 is then fixed in the locking groove 33 and cannot be disengaged, thus achieving a secure connection of the waste box 4. To disassemble, simply push the movable block 332 in the opposite direction to disengage the lock head 3321 from the latching ring 42.

[0037] The implementation principle of the fabric bonding device in this application embodiment is as follows: When the device is started, two fabrics are released by the unwinding roller 14. One fabric is sprayed with adhesive by the glue spraying mechanism 12 and then enters the area of ​​the scraper 21. The scraper 21, driven by the second motor 22, remains in contact with the fabric surface, evenly smoothing the adhesive. When the flatness of the scraper 21 surface decreases due to adhesive residue, the second motor 22 drives the rotating shaft 2 to rotate the scraper 21, so that the adhesive contact side of the scraper 21 faces the slide rail 3. Subsequently, the first motor 321 starts, driving the lead screw 322 to rotate, causing the cleaning block 31 to move along the slide rail 3. The cleaning blade 312 in the cleaning groove 311 contacts the surface of the scraper 21, scraping off the hardened adhesive; at the same time, the wiping cloth 313 performs a secondary wiping of the scraper 21 to ensure that there is no residue on the surface of the scraper 21. Waste material falls into the receiving cavity 41 of the waste box 4 through the cleaning groove 311 for centralized collection. After cleaning is completed, the cleaning block 31 is reset, the scraper 21 is rotated back to the working position, and the device resumes the fabric bonding operation.

[0038] This application also discloses a high-strength tear-resistant fabric structure. (Refer to...) Figure 4This application utilizes a fabric bonding device, comprising a base fabric layer 51, a tear-resistant layer 52, and a cover layer 53. The tear-resistant layer 52 is located between the base fabric layer 51 and the cover layer 53, and is hot-pressed onto the surface of the cover layer 53. The base fabric layer 51 and the tear-resistant layer 52 are bonded together using the fabric bonding device. The base fabric layer 51 is made of high-density polyester weave, providing basic support and abrasion resistance. The tear-resistant layer 52 is made of aramid fibers woven in a bidirectional cross-weave pattern to form a mesh structure, giving the fabric extremely high tear resistance and energy absorption capacity. The cover layer 53 is made of ultra-high molecular weight polyethylene film, which is composited with the tear-resistant layer 52 through a hot-pressing process to form an abrasion-resistant surface. The base fabric layer 51 and the tear-resistant layer 52 are bonded together by uniformly applying adhesive through the fabric bonding device and high-pressure bonding with a compaction roller 13, achieving a seamless interlayer bond. The fabric can still suppress crack propagation under extreme external forces while maintaining lightweight and flexibility.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
