Description

Technical Field

[0001] The present invention relates to the technical field of fabric production equipment, and particularly relates to an equipment for producing multi-layer nano-thermal radiation fabrics. Background Art

[0002] With the rapid development of technology and the increasing attention to environmental protection and energy utilization efficiency by people, nano materials and their applications have gradually become a research hotspot. By laminating materials with different functions together, multi-layer nano-thermal radiation fabrics can give full play to the characteristics of each layer of materials and form a composite effect.

[0003] After retrieval, a Chinese patent document with the patent number CN202110971434.6 discloses a high-strength TPU multi-layer composite fabric production equipment. In the above solution, glue flows out from the glue brush roller, and the telescopic plate will scrape the surface of the glue brush roller flat, so that the glue adheres to the glue brush roller evenly and then the glue is brushed on the fabric. Thus, it can be realized that the glue adheres to the fabric evenly during glue brushing, preventing the fabric from delaminating after lamination.

[0004] In the above technology, although the glue can be evenly coated on the fabric surface, for the composite production of multi-layer nano-thermal radiation fabrics, the upper and lower surfaces of the fabric located inside both need to be coated with a composite agent. Therefore, when coating the fabric with the composite agent, double-sided synchronous coating operation is required. At the same time, for fabrics made of different materials, the coating methods of the composite agent are also different. For fabrics with a higher density, with the conventional coating method, the composite agent cannot penetrate into the fabric interior, resulting in a poor composite connection effect between the fabrics. Summary of the Invention

[0005] Technical Problems to be Solved

[0006] Aiming at the above-mentioned disadvantages of the prior art, the present invention provides an equipment for producing multi-layer nano-thermal radiation fabrics, which can solve the problem that the composite agent cannot penetrate into the fabric interior when coating the composite agent on the fabric surface in the prior art.

[0007] Technical Solutions

[0008] To achieve the above purposes, the present invention is realized through the following technical solutions:

[0009] The present invention provides a device for producing a multi-layer nano thermal radiation fabric, which includes a mounting frame. A feeding roller, a coating device, a squeezing roller and a winding roller are sequentially installed on the mounting frame. The feeding rollers are arranged in several groups and distributed vertically. The number of feeding rollers, fabrics and coating devices is adapted to each other. A guiding roller is also installed on the mounting frame. Several groups of fabrics pass through the corresponding coating devices under the guiding action of the guiding roller, converge and then pass through the squeezing roller, and finally are connected to the winding roller. The coating device includes two coating mechanisms. The fabric passes between the two coating mechanisms. The two coating mechanisms are installed between two fixed seats on the mounting frame. The coating mechanism is used for brushing a composite agent on the surface of the fabric and pressing the composite agent to penetrate into the fabric.

[0010] Further, the coating mechanism includes a coating nozzle installed between two fixed seats. One end of the coating nozzle is installed in a medicine tank which is connected in communication. The other end of the coating nozzle faces the fabric and is provided with uniformly distributed one-way valve nozzles.

[0011] Further, the coating mechanism further includes a mounting shaft inserted on the fixed seat. A control wheel is installed on the surface of the mounting shaft. A communication cavity is arranged on the side of the coating nozzle facing the control wheel. Control bumps are installed on the surface of the control wheel. A piston block is installed in the communication cavity of the coating nozzle through a spring. A motor is installed on the fixed seat. The output shaft of the motor is in transmission connection with the mounting shaft. A one-way valve is arranged at the communication part between the medicine tank and the coating nozzle.

[0012] Further, several groups of control bumps are installed on the surface of the control wheel. The several groups of control bumps are distributed in an equidistant circular pattern.

[0013] Further, the outer end surface of the control bump is set to be pointed.

[0014] Further, the side surface of the coating nozzle provided with one-way valve nozzles is set to be an arc surface. A chute is arranged on the arc surface of the coating nozzle. The chutes are distributed in one-to-one correspondence below the one-way valve nozzles. Two baffle plates are inserted and installed in the chutes.

[0015] Further, a fixed rod is fixedly connected to the coating nozzle. Threaded holes are linearly distributed on the vertical section surface of the fixed rod. A connecting rod is installed on the fixed rod through bolts and threaded holes. The connecting rod is used for smoothing the composite agent on the surface of the fabric.

[0016] Further, the connecting rod is set to be equilateral triangular and the triangular tip faces the coating nozzle side.

[0017] Further, a liquid collecting box is fixedly connected to the surface of the coating nozzle in the coating mechanism located below the fabric. The length of the liquid collecting box is greater than the length of the connecting rod.

[0018] Further, gears are fixedly connected to the surfaces of the same ends of the two groups of mounting shafts, and the two groups of gears are meshed and connected. The output shaft of the motor is in transmission connection with one of the mounting shafts.

[0019] Advantages and effects

[0020] The technical solution provided by the present invention has the following advantages and effects compared with the known public technologies:

[0021] Through the structural arrangement of the gluing device of the present invention, when the fabric is glued through the gluing device, the fabric will pass through the two gluing mechanisms in the gluing device, further enabling the fabric to be synchronously brushed on both sides during the gluing process, thereby improving the brushing efficiency;

[0022] Moreover, when the gluing mechanism glues the surface of the fabric, it will make the composite agent penetrate into the interior of the fabric by means of injection pressure and form a stronger mechanical bond with the fibers of the fabric, thereby enhancing the adhesion between the fabric layers and improving the overall strength of the multi-layer fabric;

[0023] Meanwhile, before the fabric is glued, indentations can be generated on the surface of the fabric to increase the roughness of the fabric surface, provide more space for the inflow of the composite agent, and enhance the bite between the composite agent and the fabric fibers, thereby improving the bonding strength between the multi-layer fabrics.

[0024] And after the fabric completes the gluing operation, the composite agent on the surface of the fabric can be evenly brushed and the excess composite agent can be diverted and collected to reduce the waste of materials. Description of the drawings

Detailed implementation manners

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Embodiment:

[0037] Please refer to the attached Figure 1-7, this solution proposes a device for producing multi-layer nano-thermal radiation fabrics. At both ends of the mounting frame 1, a feeding roller 2 and a winding roller 3 are respectively installed. The feeding roller 2 is used to fix and unwind the fabric 4 to be compounded, and the winding roller 3 is used to wind the compounded fabric 4. The feeding rollers 2 are arranged in several groups and distributed vertically. The number of feeding rollers 2 is adapted to the number of fabrics 4 to be compounded. According to the vertical position relationship of several groups of fabrics 4, several groups of fabrics 4 are successively installed on several groups of feeding rollers 2, so that several groups of fabrics 4 can be accurately compounded and connected according to the production standard. A guiding roller 5 is installed on the surface of the mounting frame 1, and the guiding roller 5 is used to guide the transmission of the fabric 4. Several groups of gluing devices 6 are also installed on the surface of the mounting frame 1. The number of gluing devices 6 is adapted to the number of feeding rollers 2. So that the fabric 4 on the feeding roller 2 will pass through the gluing device 6 under the guiding action of the guiding roller 5, and the compounding agent is brushed on the surface of the fabric 4 through the gluing device 6. Two groups of pressing rollers 7 are installed on the surface of the mounting frame 1. After several groups of fabrics 4 are all brushed with the compounding agent through the gluing device 6, they will all pass through the two groups of pressing rollers 7 under the guiding action of the guiding roller 5. By running the two groups of pressing rollers 7, several groups of fabrics 4 can be pressed, so that several groups of fabrics 4 are bonded together through the compounding agent to form a compound connection of multi-layer fabrics 4. The pressing roller 7 is installed on the mounting frame 1 through an electric telescopic rod 8, and the distance between the two groups of pressing rollers 7 can be adjusted through the electric telescopic rod 8, so that the two groups of pressing rollers 7 can press and connect fabrics 4 with different numbers of layers and thicknesses. Finally, the bonded fabric 4 will be wound and collected by the winding roller 3 to complete the collection.

[0038] Specifically, the gluing device 6 includes fixing seats 601 installed on the mounting frame 1. The fixing seats 601 are arranged in two groups and are respectively installed on both sides of the mounting frame 1. Two gluing mechanisms are installed between the two groups of fixing seats 601. Under the guiding action of the guiding roller 5, the fabric 4 will pass through between the two gluing mechanisms, so that the surface of the fabric 4 can be simultaneously brushed with the compounding agent on both sides according to the gluing requirements.

[0039] More specifically, the gluing mechanism includes a glue nozzle 602 installed between the two groups of fixing seats 601. The glue nozzle 602 is set in a "T" shape. A medicament tank 615 is installed on the surface of one end of the glue nozzle 602 and is connected. On the surface of the end of the glue nozzle 602 facing the fabric 4, one-way valve nozzles 603 are evenly distributed. Through the glue nozzle 602, the compounding agent in the medicament tank 615 can be discharged, and the compounding agent is brushed on the surface of the fabric 4 through the one-way valve nozzles 603, which is convenient for the subsequent bonding between several groups of fabrics 4.

[0040] The gluing mechanism further includes a mounting shaft 604 inserted into the fixed seat 601. A control wheel 605 is fixedly connected to the surface of the mounting shaft 604. The other end of the glue applicator nozzle 602 faces the side of the control wheel 605. A control projection 606 is mounted on the surface of the control wheel 605. A piston block 607 is inserted into the end of the glue applicator nozzle 602 facing the control wheel 605. One end of the piston block 607 inserted into the glue applicator nozzle 602 is fixedly connected to a spring 608. The other end of the spring 608 is connected to the inner wall of the glue applicator nozzle 602. Under the elastic force of the spring 608, the piston block 607 will be pushed out from the inside of the glue applicator nozzle 602 and abutted against the surface of the control wheel 605. A motor 611 is mounted on the surface of the fixed seat 601. The output shaft of the motor 611 is in transmission connection with the mounting shaft 604 of one set of gluing mechanisms. When the fabric 4 passes between the two sets of gluing mechanisms, the motor 611 is started to operate, and the gluing mechanism is controlled to automatically brush the composite agent on the surface of the fabric 4. When the mounting shaft 604 rotates, it drives the control wheel 605 to rotate. Further, the control wheel 605 drives the control projection 606 to rotate. During the rotation process, the control projection 606 will periodically contact the piston block 607. When the control projection 606 abuts against the surface of the piston block 607, it will push the piston block 607 to slide into the glue applicator nozzle 602 and compress the spring 608. When the piston block 607 slides into the glue applicator nozzle 602, it will simultaneously compress the composite agent in the glue applicator nozzle 602, so that the composite agent is discharged through the one-way valve nozzle 603 after being pressurized, further realizing the brushing of the composite agent on the surface of the fabric 4. And after the composite agent is discharged under pressure, the composite agent will penetrate into the interior of the fabric 4 under the action of pressure and form a stronger mechanical bond with the fibers of the fabric 4, thereby enhancing the adhesion between the fabric layers 4 and improving the overall strength of the multi-layer fabric.

[0041] A one-way valve is provided at the connection between the medicine tank 615 and the glue applicator nozzle 602, so that the composite agent in the medicine tank 615 can only be transported unidirectionally into the glue applicator nozzle 602. When the control wheel 605 continues to rotate, the control projection 606 cannot abut against the surface of the piston block 607. Therefore, the piston block 607 will be pushed out from the glue applicator nozzle 602 under the elastic force of the spring 608. During the process of the piston block 607 sliding outwards in the glue applicator nozzle 602, it will suck the composite agent in the medicine tank 615 into the glue applicator nozzle 602, further realizing the replenishment of the composite agent in the glue applicator nozzle 602, which is convenient for the next piston movement of the piston block 607 to discharge the composite agent in the glue applicator nozzle 602 for the next time.

[0042] At the same time, a number of control projections 606 are mounted on the surface of the control wheel 605. The number of control projections 606 is evenly distributed in a circular pattern at equal distances. By setting the number of control projections 606, the control frequency of the piston block 607 can be adjusted to realize the control of the brushing frequency of the composite agent, which is convenient for evenly brushing the composite agent on the surface of the fabric 4 and avoiding waste of the composite agent due to excessive dosage of the composite agent.

[0043] In contrast, the surface of the glue applicator nozzle 602 on the side where the one-way valve nozzle 603 is provided is set as an arc-shaped surface. Further, after the glue applicator nozzle 602 abuts against the surface of the fabric 4, when the glue application device 6 slides on the surface of the glue applicator nozzle 602, the frictional force between the glue applicator nozzle 602 and the fabric 4 can be reduced, avoiding scratching the surface of the fabric 4.

[0044] A chute 609 is further provided on the surface of the glue applicator nozzle 602 on the side where the one-way valve nozzle 603 is provided. The number of chutes 609 is adapted to the number of one-way valve nozzles 603, and several groups of chutes 609 are distributed in a one-to-one correspondence below the one-way valve nozzles 603. Two baffles 610 are inserted and installed inside the chute 609. By sliding the baffle 610 in the chute 609, the one-way valve nozzle 603 can be shielded, further enabling the one-way valve nozzle 603 to control the discharge dose of the composite agent. Through the independent adjustment of several groups of one-way valve nozzles 603, when the glue application device 6 applies the composite agent to the surface of the fabric 4, the application position and application dose on the surface of the fabric 4 can be controlled, further realizing the precise control of the composite agent and improving the composite connection effect between the fabrics 4. Moreover, the sliding of the baffle 610 in the chute 609 has a damping effect, enabling the baffle 610 to be fixed after sliding, thereby maintaining effective control over the exposure size of the one-way valve nozzle 603.

[0045] The outer end surface of the control bump 606 is set to be pointed. When the two glue application mechanisms operate synchronously, the two control wheels 605 will clamp the fabric 4. And when the two control wheels 605 are in a relatively static state, the control bumps 606 on the surfaces of the two control wheels 605 are staggered. Further, when the control wheels 605 rotate, the control bumps 606 will squeeze the fabric 4, further causing creases to appear on the surface of the fabric 4 and increasing the roughness of the surface of the fabric 4. The rough surface can provide more space for the inflow of the composite agent, enhancing the bite between the composite agent and the fibers of the fabric 4, thereby improving the bonding strength between multiple layers of the fabric 4.

[0046] A fixing rod 613 is fixedly connected to the surface of the glue applicator nozzle 602. The fixing rod 613 is set in an "L" shape, and threaded holes are linearly distributed on the vertical section surface of the fixing rod 613. A connecting rod 614 is installed on the fixing rod 613 through bolts and the threaded holes. When the glue applicator nozzle 602 abuts against the surface of the fabric 4 for glue application operation, when the fabric 4 slides on the surface of the connecting rod 614, the connecting rod 614 can scrape and level the composite agent on the surface of the fabric 4, further improving the bonding effect of the composite agent on the surface of the fabric 4.

[0047] The connecting rod 614 is arranged in an equilateral triangle shape, and the triangular tip faces the side of the glue applicator nozzle 602. Further, when the connecting rod 614 spreads and levels the compound on the surface of the fabric 4 during the conveying process of the fabric 4, the excess compound will be pushed to both sides, further realizing the discharge of the excess compound on the surface of the fabric 4. A liquid collecting box 616 is fixedly connected to the surface of the glue applicator nozzle 602 in the glue applying mechanism below the fabric 4. The length of the liquid collecting box 616 is greater than the length of the connecting rod 614. Further, the connecting rod 614 in the upper glue applying mechanism will divert the excess compound into the liquid collecting box 616 to realize the collection of the excess compound. By adjusting the height of the connecting rod 614 on the fixed rod 613, the distance between the connecting rod 614 and the surface of the fabric 4 can be further controlled to form different spacings, and the compound can be scraped at different heights, further increasing the structural functionality of the device.

[0048] It should be noted that gears 612 are fixedly connected to the surfaces of the same ends of the two sets of mounting shafts 604, and the two sets of gears 612 are meshed. After the motor 611 is turned on, it will synchronously drive the control wheels 605 in the two sets of glue applying mechanisms to rotate, further controlling the two sets of glue applying mechanisms to operate synchronously. And the rotation directions of the two control wheels 605 in the two sets of glue applying mechanisms are opposite, so that during the rotation of the two control wheels 605, the fabric 4 can be pushed to slide to one side, further realizing the rapid passing of the fabric 4 between the two sets of glue applying mechanisms, and thus improving the glue applying efficiency of the glue applying device 6 to the fabric 4.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
