Description

Technical Field

[0001] This invention relates to the field of fabric technology, and in particular to a multi-layer textile fabric and its production line. Background Technology

[0002] Fabric generally refers to the materials used to make clothing. In order to make fabrics have different functions, different fabrics are usually bonded together in the prior art. For example, patent document with application number 202121785169.4 discloses a functional fabric with a multi-layer composite structure, which has a fire-retardant layer, a wear-resistant and anti-oxidation layer bonded to the top of the fire-retardant layer, a radiation-proof layer bonded to the bottom of the fire-retardant layer, a tensile fiber layer bonded to the bottom of the radiation-proof layer, a water-absorbing and breathable layer bonded to the bottom of the tensile fiber layer, and an antibacterial fiber layer bonded to the bottom of the water-absorbing and breathable layer.

[0003] In existing technologies, multi-layered fabrics are typically bonded together using adhesives. However, this method often results in the fabric edges easily coming apart after bonding, leading to insufficient overall fabric strength. In view of this, the inventors conducted in-depth research to address the aforementioned shortcomings of existing technologies, resulting in this invention. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, one object of the present invention is to provide a multi-layered textile fabric with high overall strength, good insect-proof, radiation-proof, and sweat-absorbing properties.

[0005] The second objective of this invention is to provide a production line for multi-layer textile fabrics, which can bond and press together insect-repellent fabric, middle layer fabric and sweat-absorbing fabric, resulting in high overall fabric strength, good insect-repellent, radiation-proof and sweat-absorbing effects, and effective material bonding and pressing at the edges of the fabric, making the edges of the fabric less likely to come apart.

[0006] To achieve the above objectives, one embodiment of the present invention provides a multilayer textile fabric, including an insect-repellent fabric, a middle layer fabric, and a sweat-absorbing fabric; the insect-repellent fabric includes an insect-repellent layer and a first soft connecting layer connected to the insect-repellent layer; the middle layer fabric includes a radiation-proof layer, which includes multiple connecting holes, and one side of the radiation-proof layer is connected to the first soft connecting layer through a first adhesive layer; the sweat-absorbing fabric includes a sweat-absorbing layer and a second soft connecting layer connected to the sweat-absorbing layer, and the second soft connecting layer is connected to the other side of the radiation-proof layer through a second adhesive layer, and the second soft connecting layer is connected to the first soft connecting layer through vertical adhesive layers within the connecting holes.

[0007] Furthermore, the insect-proof layer is woven from polypropylene fibers, flax fibers, and cotton fibers and then impregnated with an insect-proof and antibacterial liquid.

[0008] Furthermore, the insect-repellent and antibacterial solution includes 2-4 parts of dextromethorphan, 2-4 parts of deltamethrin, 2-4 parts of pyraclostrobin, 2-4 parts of difenoconazole, 3-6 parts of eucalyptus oil, 3-6 parts of camphor oil, 3-6 parts of citronella oil, and 66-83 parts of water.

[0009] Furthermore, the radiation shielding layer is formed by weaving nylon filaments, nano-silver fibers, and cotton fibers and then dyeing and finishing processes.

[0010] Furthermore, the sweat-absorbing layer is woven from flax fiber, ramie fiber, and jute fiber.

[0011] With the above structure, the multilayer textile fabric of the present invention has at least the following beneficial effects:

[0012] In use, the insect-repellent fabric effectively repels insects, the middle layer fabric effectively protects against radiation, and the sweat-absorbing fabric effectively absorbs sweat, resulting in excellent insect-repellent, radiation-protective, and sweat-absorbing properties. By incorporating multiple connecting holes in the radiation-protective layer, one side of the radiation-protective layer is connected to the first flexible connecting layer via a first adhesive layer, and the second flexible connecting layer is connected to the other side of the radiation-protective layer via a second adhesive layer. The second flexible connecting layer is also connected to the first flexible connecting layer via vertical adhesive layers within the connecting holes, ensuring that the insect-repellent fabric, middle layer fabric, and sweat-absorbing fabric are adjacent to each other, resulting in high overall fabric strength.

[0013] To achieve the above objectives, a second aspect of the present invention provides a production line for multilayer textile fabrics, including a pressing device for pressing together an insect-repellent fabric, a middle layer fabric, and a sweat-absorbing fabric. The pressing device includes a machine base, a feeding device, a glue supply device, a pressing device, a vertical pressing device, an inclined pressing device, and an edge pressing device.

[0014] The feeding device is mounted on the machine base and includes multiple feeding rollers for feeding insect-repellent fabric, middle layer fabric, and sweat-absorbing fabric. The glue supply device is mounted on the machine base to supply glue to both sides of the middle layer fabric. The pressing device is mounted on the machine base to press the insect-repellent fabric, the middle layer fabric with glue on both sides, and the sweat-absorbing fabric together. The vertical pressing device is mounted on the machine base to vertically press the pressed fabric together. The oblique pressing device is mounted on the machine base to obliquely press the vertically pressed fabric outwards. The edge pressing device is mounted on the machine base to press the edges of the obliquely pressed fabric together.

[0015] Furthermore, the feeding device includes a mounting frame, an insect-repellent fabric feeding roller, a middle layer fabric feeding roller, and a sweat-absorbing fabric feeding roller; the mounting frame is fixed on the machine base, the insect-repellent fabric feeding roller is rotatably mounted on the mounting frame, the middle layer fabric feeding roller is rotatably mounted on the mounting frame, the middle layer fabric feeding roller is located between the insect-repellent fabric feeding roller and the sweat-absorbing fabric feeding roller, and the sweat-absorbing fabric feeding roller is rotatably mounted on the mounting frame.

[0016] Furthermore, the glue supply device includes a fixed frame and a glue supply roller. The fixed frame is mounted on the machine base. The glue supply roller has glue on its surface. The glue supply roller includes a first glue supply roller and a second glue supply roller. The first glue supply roller is rotatably mounted on the fixed frame, and the second glue supply roller is rotatably mounted on the fixed frame. The second glue supply roller is arranged opposite to the first glue supply roller, and a space is formed between the second glue supply roller and the first glue supply roller for the middle layer fabric to pass through.

[0017] Furthermore, the first glue supply roller contacts the upper side of the middle layer fabric, the second glue supply roller contacts the lower side of the middle layer fabric, the second glue supply roller is staggered from the first glue supply roller, and the distance between the second glue supply roller and the feeding device is less than the distance between the first glue supply roller and the feeding device.

[0018] Furthermore, the pressing device includes a connecting seat and a pressing roller. The connecting seat is fixed on the machine base, and the pressing roller is rotatably mounted on the connecting seat.

[0019] Furthermore, the vertical pressing device includes a vertical pressing frame and a vertical pressing roller. The vertical pressing frame is adjustablely mounted on the machine base, and the vertical pressing roller is rotatably mounted on the vertical pressing frame.

[0020] Furthermore, the inclined pressing device includes a first inclined pressing frame, a first inclined pressing roller, a second inclined pressing frame, and a second inclined pressing roller. The first inclined pressing frame is adjustablely mounted on one side of the machine base, and the first inclined pressing roller is rotatably mounted on the first inclined pressing frame. The second inclined pressing frame is adjustablely mounted on the other side of the machine base, and the second inclined pressing roller is rotatably mounted on the second inclined pressing frame.

[0021] Furthermore, the first inclined pressure roller is set to tilt upwards, and the second inclined pressure roller is set to tilt downwards.

[0022] Furthermore, the end of the second inclined pressure roller is located below the end of the first inclined pressure roller.

[0023] Furthermore, the pressing device includes a first pressing frame, a first pressing roller, a second pressing frame, and a second pressing roller. The first pressing frame is adjustablely mounted on one side of the machine base, the first pressing roller is rotatably mounted on one side of the pressing frame, the second pressing frame is adjustablely mounted on the other side of the machine base, and the second pressing roller is rotatably mounted on the other side of the pressing frame.

[0024] Furthermore, it also includes a stamping device, which is set on one side of the pressing device. The stamping device stamps the middle layer fabric to form multiple connecting holes.

[0025] Furthermore, the stamping setup includes an upper die and a lower die. The upper die is provided with multiple punches, and the lower die is provided with multiple punch holes corresponding to the multiple punches. The lower die and the upper die can be close to each other or far apart from each other.

[0026] With the above structure, the production line for multi-layer textile fabrics disclosed in this invention has at least the following beneficial effects:

[0027] First, by setting up a pressing device, the pressing device can press together the insect-repellent fabric, the middle layer fabric with glue on both sides, and the sweat-absorbing fabric; the vertical pressing device presses the pressed fabric vertically; the oblique pressing device presses the vertically pressed fabric obliquely outward; and the edge pressing device presses the edge of the obliquely pressed fabric. By vertically pressing the fabric together, the insect-repellent fabric, the middle layer fabric, and the sweat-absorbing fabric are initially bonded together. Then, the oblique pressing device presses the vertically pressed fabric outward at an angle to further improve the strength of the fabric, further bonding the insect-repellent fabric, the middle layer fabric, and the sweat-absorbing fabric together. At the same time, the oblique pressing of the fabric allows excess glue in the middle of the insect-repellent fabric, the middle layer fabric, and the sweat-absorbing fabric to be squeezed to the edges, preventing excessive glue from affecting the overall performance of the fabric. Finally, the edge pressing device presses the edges of the obliquely pressed fabric together. Because the oblique pressing device squeezes excess glue to the edges, the edge pressing device presses the edges together, resulting in high edge strength of the multi-layered fabric after pressing.

[0028] Second, by setting up an inclined pressing device, the fabric does not need to be stopped for pressing when pressed outwards at an angle. The fabric can be pressed while being conveyed, which is highly efficient. At the same time, the fabric is less likely to be damaged during inclined pressing. Existing technologies use structures that perform transverse pressing, which employs two methods: one is to stop the fabric conveying and then perform transverse pressing, which has a good pressing effect but low efficiency; the other is to perform transverse pressing while conveying, but since the conveying direction is perpendicular to the pressing direction, the surface layer of the fabric is easily damaged when performing transverse pressing while conveying. In addition, transverse pressing requires a power mechanism such as a cylinder to move the transverse rollers laterally, which is costly.

[0029] Compared with existing technologies, this invention, through the installation of a pressing device, can perform vertical pressing, oblique pressing, and edge pressing of the fabric. Through multiple pressing processes, the fabric strength is greatly enhanced. Oblique pressing of the fabric allows excess adhesive in the middle of the fabric to be squeezed to the edges, preventing excessive adhesive from affecting the overall performance of the fabric. The oblique pressing device squeezes excess adhesive to the edges, and the edge pressing device presses the edges together, resulting in high edge strength of the multi-layered fabric after pressing. Furthermore, this invention achieves simultaneous conveying and pressing, resulting in high overall efficiency. Attached Figure Description

Detailed Implementation

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figure 1 and Figure 2As shown in the figure, a multilayer textile fabric according to an embodiment of the present invention includes an insect-repellent fabric 1, a middle layer fabric 2, and a sweat-absorbing fabric 3; the insect-repellent fabric 1 includes an insect-repellent layer 11 and a first soft connecting layer 12 connected to the insect-repellent layer 11; the middle layer fabric 2 includes a radiation-proof layer, which includes a plurality of connecting holes 21, and one side of the radiation-proof layer is connected to the first soft connecting layer 12 through a first adhesive layer 4; the sweat-absorbing fabric 3 includes a sweat-absorbing layer 31 and a second soft connecting layer 32 connected to the sweat-absorbing layer 31, the second soft connecting layer 32 is connected to the other side of the radiation-proof layer through a second adhesive layer 5, and the second soft connecting layer 32 is connected to the first soft connecting layer 12 through a vertical adhesive layer 6 in the connecting hole 21.

[0041] Thus, the multi-layer textile fabric of the present invention, when in use, has an insect-repellent fabric 1 that effectively repels insects, a middle layer fabric 2 that effectively protects against radiation, and a sweat-absorbing fabric 3 that effectively absorbs sweat, resulting in good insect-repellent, radiation-protective, and sweat-absorbing effects. By setting multiple connecting holes 21 in the radiation-protective layer, one side of the radiation-protective layer is connected to the first flexible connecting layer 12 through a first adhesive layer 4, and the second flexible connecting layer 32 is connected to the other side of the radiation-protective layer through a second adhesive layer 5. The second flexible connecting layer 32 is also connected to the first flexible connecting layer 12 through vertical adhesive layers 6 within the connecting holes 21, making the insect-repellent fabric 1, the middle layer fabric 2, and the sweat-absorbing fabric 3 adjacent to each other, resulting in high overall fabric strength.

[0042] Optionally, the insect-repellent layer 11 is woven from polypropylene fibers, flax fibers, and cotton fibers and then impregnated with an insect-repellent and antibacterial liquid. Polypropylene is the Chinese trade name for isotactic polypropylene fiber, a synthetic fiber made from propylene, a byproduct of petroleum refining. It is also known as polypropylene fiber and is characterized by high strength, good elasticity, and wear resistance. Flax fiber is a rare natural fiber with properties such as moisture absorption and heat dissipation, health benefits and antibacterial properties, stain resistance, antistatic properties, and UV protection. Cotton fiber is a seed fiber formed from the epidermal cells of fertilized ovules through elongation and thickening. Unlike ordinary bast fibers, cotton fiber has high strength and good breathability. The insect-repellent layer 11, woven from polypropylene fibers, flax fibers, and cotton fibers, possesses high strength, good elasticity, wear resistance, moisture absorption and heat dissipation, health benefits and antibacterial properties, and good breathability. After being impregnated with an insect-repellent and antibacterial liquid, it has an insect-repellent effect.

[0043] The insect-repellent and antibacterial liquid comprises 2-4 parts dextromethorphan, 2-4 parts deltamethrin, 2-4 parts pyraclostrobin, 2-4 parts difenoconazole, 3-6 parts eucalyptus oil, 3-6 parts camphor oil, 3-6 parts citronella oil, and 66-83 parts water. Dextromethorphan is a clear, colorless to pale yellow viscous liquid with the molecular formula C23H26O3. It has contact and stomach poison effects on insects and a broad insecticidal spectrum. Eucalyptus oil is a colorless to pale yellow liquid with good antibacterial and bactericidal properties. Camphor oil is a volatile oil extracted from camphor tree roots through artificial evaporation and has medicinal functions. Citronella oil, also known as herb oil or lemongrass oil, is obtained by steam distillation of the whole lemongrass plant and can be used as an insecticide. After the insect-repellent layer 11 was soaked in an insect-repellent and antibacterial liquid, tests showed that mosquitoes would be driven away by the odor when they approached the insect-repellent layer 11, thus achieving a good insect-repellent effect.

[0044] In this example, the radiation-shielding layer is woven from nylon filaments, nano-silver fibers, and cotton fibers, and then dyed and finished. Nano-silver fiber fabric, as one type of radiation-shielding fabric, has undergone three innovations: from silver-plated fibers to traditional sputtered fabrics to nano-silver fiber fabrics. It is a silver fiber radiation-shielding fabric made from silver-containing fibers using nanotechnology. It represents the latest radiation-shielding technology after metal radiation-shielding fiber fabrics, possessing radiation-shielding, antibacterial, and stain-resistant functions, making it an ideal fabric for producing radiation-shielding clothing. It is essentially made by coating nylon fibers with a layer of silver using nanotechnology, forming highly durable silver fibers. The weaving of nylon filaments, nano-silver fibers, and cotton fibers, followed by dyeing and finishing, results in a strong radiation-shielding function.

[0045] In some examples, the absorbent layer 31 is woven from flax, ramie, and jute fibers. Flax fibers have excellent moisture absorption and wicking capabilities; ramie fibers are long, strong, and have good thermal conductivity, with moisture absorption and breathability approximately 3-5 times that of cotton fibers. It also contains beneficial elements such as benzoyl peroxide, pyrimidine, and purines, providing antibacterial, breathable, cooling, antiseptic, anti-mildew, and sweat-absorbing functions. Jute fiber is one of the most inexpensive natural fibers, second only to cotton in both cultivation volume and wide range of applications. Jute fiber is white, lustrous, and has excellent moisture absorption and rapid moisture wicking. The woven fabric of flax, ramie, and jute fibers gives the absorbent layer 31 its strong sweat-absorbing function.

[0046] like Figures 3 to 7As shown in the figure, the present invention also proposes a production line for multi-layer textile fabrics, including a pressing device 7 for pressing insect-repellent fabric 1, middle layer fabric 2 and sweat-absorbing fabric 3 together. The pressing device 7 includes a machine base 71, a feeding device 72, a glue supply device 73, a pressing device 74, a vertical pressing device 75, an oblique pressing device 76 and an edge pressing device 77. A feeding device 72 is mounted on a machine base 71. The feeding device 72 includes multiple feeding rollers for feeding the insect-repellent fabric 1, the middle layer fabric 2, and the sweat-absorbing fabric 3. A glue supply device 73 is mounted on the machine base 71 to supply glue to both sides of the middle layer fabric 2. A pressing device 74 is mounted on the machine base 71 to press the insect-repellent fabric 1, the middle layer fabric 2 with glue on both sides, and the sweat-absorbing fabric 3 together. A vertical pressing device 75 is mounted on the machine base 71 to vertically press the pressed fabric together. A slanted pressing device 76 is mounted on the machine base 71 to slant outwards the vertically pressed fabric together. An edge pressing device 77 is mounted on the machine base 71 to press the edge of the obliquely pressed fabric together.

[0047] By setting up the pressing equipment 7, the pressing device 74 of the pressing equipment 7 can press the insect-proof fabric 1, the middle layer fabric 2 with glue on both sides and the sweat-absorbing fabric 3 together; the vertical pressing device 75 presses the pressed fabric vertically; the oblique pressing device 76 presses the fabric after vertical pressing obliquely outward; and the edge pressing device 77 presses the edge of the fabric after oblique pressing. By vertically pressing the fabrics together, the insect-repellent fabric 1, the middle layer fabric 2, and the sweat-absorbing fabric 3 are initially pressed together. Then, the oblique pressing device 76 presses the vertically pressed fabrics obliquely outward to further improve the strength of the fabrics, further pressing the insect-repellent fabric 1, the middle layer fabric 2, and the sweat-absorbing fabric 3 together. At the same time, the oblique pressing of the fabrics allows excess glue in the middle of the insect-repellent fabric 1, the middle layer fabric 2, and the sweat-absorbing fabric 3 to be squeezed to the edges, preventing excessive glue from affecting the overall performance of the fabrics. Finally, the edge pressing device 77 presses the edges of the obliquely pressed fabrics together. Because the oblique pressing device 76 squeezes excess glue to the edges, and the edge pressing device 77 presses the edges together, the edge strength of the multi-layered fabric after pressing is high.

[0048] By setting the inclined pressing device 76, the fabric does not need to be stopped for pressing when it is pressed outwards at an angle. The fabric can be pressed while being conveyed, which is highly efficient. At the same time, the fabric is less likely to be damaged during inclined pressing. Existing technologies have structures that use transverse pressing, which employs two methods: one is to stop the fabric conveying and then perform transverse pressing, which has a good pressing effect but low efficiency; the other is to press transversely while conveying, but since the conveying direction is perpendicular to the pressing direction, the surface layer of the fabric is easily damaged when pressing transversely while conveying. In addition, transverse pressing requires a power mechanism such as a cylinder to move the transverse roller laterally, which is costly.

[0049] Optionally, the feeding device 72 includes a mounting frame 721, an insect-repellent fabric feeding roller 722, a mid-layer fabric feeding roller 723, and a sweat-absorbing fabric feeding roller 724. The mounting frame 721 is fixed on the machine base 71. The insect-repellent fabric feeding roller 722 is rotatably mounted on the mounting frame 721, and the mid-layer fabric feeding roller 723 is rotatably mounted on the mounting frame 721. The mid-layer fabric feeding roller 723 is located between the insect-repellent fabric feeding roller 722 and the sweat-absorbing fabric feeding roller 724, and the sweat-absorbing fabric feeding roller 724 is rotatably mounted on the mounting frame 721. By setting the mounting frame 721, the insect-repellent fabric feeding roller 722, the mid-layer fabric feeding roller 723, and the sweat-absorbing fabric feeding roller 724 are rotatably mounted on the mounting frame 721, facilitating the input of the insect-repellent fabric 1, the mid-layer fabric 2, and the sweat-absorbing fabric 3, so that the insect-repellent fabric 1, the mid-layer fabric 2, and the sweat-absorbing fabric 3 can be pressed together. In this example, the insect-repellent fabric 1 can be conveyed from the bottom of the insect-repellent fabric feed roller 722, while the sweat-absorbing fabric 3 can be conveyed from the rotatable top of the sweat-absorbing fabric feed roller 724. This arrangement is reasonable and facilitates the previous process of punching the middle layer fabric 2 821.

[0050] In some examples, the glue supply device 73 includes a fixed frame 731 and a glue supply roller 732. The fixed frame 731 is mounted on the machine base 71. The glue supply roller 732 has glue on its surface and includes a first glue supply roller 7321 and a second glue supply roller 7322. The first glue supply roller 7321 is rotatably mounted on the fixed frame 731, and the second glue supply roller 7322 is rotatably mounted on the fixed frame 731. The second glue supply roller 7322 is positioned opposite to the first glue supply roller 7321, and a space is formed between the second glue supply roller 7322 and the first glue supply roller 7321 for the middle layer fabric 2 to pass through. By setting the first glue supply roller 7321 and the second glue supply roller 7322, it is convenient to apply glue to the upper and lower sides of the insect-repellent fabric 1, so that the upper and lower sides of the insect-repellent fabric 1 have sufficient glue, resulting in high overall strength after bonding. The glue supply roller 732 includes an inner cylinder for holding glue, a glue inlet and a glue outlet. Glue can be injected through the glue inlet and glue can be discharged to the surface of the middle layer fabric 2 through the glue outlet. The glue supply roller 732 is prior art and will not be described in detail here.

[0051] In this example, the first glue supply roller 7321 contacts the upper side of the middle layer fabric 2, and the second glue supply roller 7322 contacts the lower side of the middle layer fabric 2. The second glue supply roller 7322 is staggered from the first glue supply roller 7321, and the distance between the second glue supply roller 7322 and the feeding device 72 is less than the distance between the first glue supply roller 7321 and the feeding device 72. That is, the upper side of the middle layer fabric 2 first contacts the first glue supply roller 7321, so that the glue on the first glue supply roller 7321 makes full contact with the upper side of the middle layer fabric 2, and partially penetrates to the lower middle side of the middle layer fabric 2 under the action of gravity. Then, the lower side of the middle layer fabric 2 contacts the second glue supply roller 7322, so that the glue on the second glue supply roller 7322 makes full contact with the lower side of the middle layer fabric 2. This ensures that there is sufficient glue on both the upper and lower sides of the middle layer fabric 2, so that the connecting hole 21 can be filled with glue, which is convenient for bonding with the insect-repellent fabric 1 and the sweat-absorbing fabric 3.

[0052] When the middle layer fabric 2 wraps around the first glue supply roller 7321 and the second glue supply roller 7322, the middle layer fabric 2 is S-shaped, allowing it to fully contact the first glue supply roller 7321 and the second glue supply roller 7322, ensuring sufficient glue on both the upper and lower sides of the middle layer fabric 2. The diameter of the second glue supply roller 7322 is smaller than that of the first glue supply roller 7321, and the glue output of the second glue supply roller 7322 is smaller than that of the first glue supply roller 7321. Since the upper side of the middle layer fabric 2 contacts the first glue supply roller 7321 first, the glue on the first glue supply roller 7321 fully contacts the upper side of the middle layer fabric 2, and under the influence of gravity, partially penetrates to the lower middle side of the middle layer fabric 2. At this point, the lower side of the middle layer fabric 2 has a small amount of glue. To ensure uniform glue distribution on both the upper and lower sides of the middle layer fabric 2, the diameter of the second glue supply roller 7322 is smaller than that of the first glue supply roller 7321. After the lower side of the middle layer fabric 2 comes into contact with the second glue supply roller 7322, the amount of glue on the lower side of the middle layer fabric 2 from the second glue supply roller 7322 is less than the amount of glue on the upper side of the middle layer fabric 2 from the first glue supply roller 7321. The amount of glue on the lower side of the middle layer fabric 2 from the second glue supply roller 7322 plus the amount of glue on the first glue supply roller 7321 that partially penetrates to the lower side of the middle layer fabric 2 under the action of gravity is approximately equal to the amount of glue on the upper side of the middle layer fabric 2 from the first glue supply roller 7321. This makes the amount of glue on the upper and lower sides of the middle layer fabric 2 more uniform.

[0053] In some examples, the pressing device 74 includes a connecting seat 741 and a pressing roller 742. The connecting seat 741 is fixed on the machine base 71, and the pressing roller 742 is rotatably mounted on the connecting seat 741. In this way, the insect-repellent fabric 1, the middle layer fabric 2, and the sweat-absorbing fabric 3 are initially pressed together by the pressing device 74. The adhesive on the upper and lower sides of the middle layer fabric 2 is in full contact with the insect-repellent fabric 1 and the sweat-absorbing fabric 3, resulting in a good pressing effect.

[0054] Furthermore, the vertical pressing device 75 includes a vertical pressing frame 751 and a vertical pressing roller 752. The vertical pressing frame 751 is adjustablely mounted on the machine base 71, and the vertical pressing roller 752 is rotatably mounted on the vertical pressing frame 751. By setting the vertical pressing roller 752, when the fabric pressed by the pressing device 74 passes through the vertical pressing roller 752, the vertical pressing roller 752 applies vertical pressure to the fabric, thereby further pressing the insect-repellent fabric 1, the middle layer fabric 2, and the sweat-absorbing fabric 3, and improving their strength. At the same time, since the vertical pressing frame 751 is adjustablely mounted on the machine base 71, the distance between the vertical pressing roller 752 and the surface of the machine base 71 can be adjusted, facilitating the pressing of fabrics of different thicknesses.

[0055] As an example, the inclined pressing device 76 includes a first inclined pressing frame 761, a first inclined pressing roller 762, a second inclined pressing frame 763, and a second inclined pressing roller 764. The first inclined pressing frame 761 is adjustablely mounted on one side of the machine base 71, the first inclined pressing roller 762 is rotatably mounted on the first inclined pressing frame 761, the second inclined pressing frame 763 is adjustablely mounted on the other side of the machine base 71, and the second inclined pressing roller 764 is rotatably mounted on the second inclined pressing frame 763. By adjusting the first inclined pressing frame 761 and the second inclined pressing frame 763, the distance between the first inclined pressing roller 762 and the second inclined pressing roller 764 and the surface of the machine base 71 can be easily adjusted, thereby accommodating fabrics of different thicknesses. The adjustable height of the first inclined pressing frame 761 and the second inclined pressing frame 763 on the machine base 71 is prior art and will not be described in detail here.

[0056] By setting up a first inclined pressure roller 762 and a second inclined pressure roller 764, when the fabric moves under the traction of the traction roller, it drives the first inclined pressure roller 762 and the second inclined pressure roller 764 to rotate, thus achieving a situation where the fabric moves while the first inclined pressure roller 762 and the second inclined pressure roller 764 rotate simultaneously. The fabric movement drives the first inclined pressure roller 762 and the second inclined pressure roller 764 to rotate, eliminating the need for a power mechanism and resulting in low cost.

[0057] Traditional fabric pressing uses rollers for lateral pressing, which has two methods. One method requires stopping the fabric to allow the lateral rollers to press together, effectively bonding different fabric layers. Because stopping the fabric means stopping the traction rollers, this is inefficient. The other method involves the fabric moving while the lateral rollers press. However, since the fabric's movement is perpendicular to the lateral rollers' movement, the fabric slides and rubs against the outer surface of the lateral rollers, easily damaging the fabric surface. Furthermore, this lateral pressing method requires a power mechanism to drive the lateral rollers, resulting in high costs. The first inclined pressure roller 762 and second inclined pressure roller 764 of this invention, compared to traditional lateral rollers, do not require stopping the fabric, resulting in high efficiency. The fabric movement directly drives the first inclined pressure roller 762 and second inclined pressure roller 764, preventing damage to the fabric surface. Additionally, the absence of a power mechanism to drive the first inclined pressure roller 762 and second inclined pressure roller 764 reduces costs.

[0058] As an example, the first inclined pressure roller 762 is inclined upward, and the second inclined pressure roller 764 is inclined downward. In this way, the first inclined pressure roller 762 and the second inclined pressure roller 764 are roughly V-shaped, which facilitates the outward extrusion of excess glue in the middle of the fabric, while further pressing the fabric together and making the fabric stronger.

[0059] Furthermore, the end of the second inclined pressure roller 764 is located below the end of the first inclined pressure roller 762, so that excess glue in the middle of the fabric can be fully squeezed outward.

[0060] In some examples, the edge-pressing device 77 includes a first edge-pressing frame 771, a first edge-pressing roller 772, a second edge-pressing frame 773, and a second edge-pressing roller 774. The first edge-pressing frame 771 is adjustablely mounted on one side of the machine base 71, the first edge-pressing roller 772 is rotatably mounted on one side of the edge-pressing frame, the second edge-pressing frame 773 is adjustablely mounted on the other side of the machine base 71, and the second edge-pressing roller 774 is rotatably mounted on the other side of the edge-pressing frame. By adjusting the first edge-pressing frame 771 and the second edge-pressing frame 773, the height of the first edge-pressing roller 772 and the second edge-pressing roller 774 can be easily adjusted, thus adapting to fabrics of different thicknesses. The first edge-pressing roller 772 and the second edge-pressing roller 774 can effectively press the edge of the fabric together. Under the action of the first inclined pressure roller 762 and the second inclined pressure roller 764, excess glue in the middle of the fabric is squeezed outward to the edge, and then pressed by the first edge-pressing roller 772 and the second edge-pressing roller 774, making the edge of the fabric strong and less prone to unraveling.

[0061] In some examples, a stamping device 8 is also included, which is located on one side of the pressing device 7. The stamping device stamps the middle layer fabric 2 to form multiple connecting holes 21. The stamping device includes an upper die 81 and a lower die 82. The upper die 81 is provided with multiple punches 811, and the lower die 82 is provided with multiple punches 821 corresponding to the punches 811. The lower die 82 and the upper die 81 can be close to or far from each other. When the middle layer fabric 2 passes through the upper die 81 and the lower die 82, the multiple punches 811 on the upper die 81 press downwards, thereby stamping the middle layer fabric 2 to form multiple connecting holes 21. Finally, it passes through the take-up roller 83 for take-up. After the take-up roller 83 takes up the material, it is moved to the mounting frame 721 to form the middle layer fabric feed roller 723.

[0062] As an example, the pressing device 7 also includes an anti-wrinkle device 9, which is mounted on the machine base 71 and located between the pressing device 74 and the vertical pressing device 75 to prevent wrinkles from forming on the fabric. The anti-wrinkle device 9 includes an anti-wrinkle frame 91 and an anti-wrinkle roller 92. The anti-wrinkle frame 91 is mounted on the machine base 71 and has a groove. The end of the anti-wrinkle roller 92 is slidably mounted in the groove via a bearing. One end of a spring is connected to the bottom of the bearing, and the other end of the spring is connected to the bottom of the groove. By setting up the anti-wrinkle device 9, the fabric pressed by the pressing device 74 can be lifted by the anti-wrinkle roller 92, preventing the fabric from sticking to the surface of the machine base 71 and causing wrinkles. The anti-wrinkle roller 92 is adjustable; when the fabric is pulled by the traction roller, the spring is compressed. When traction stops, the fabric is pressed tightly by the anti-wrinkle roller 92, making this part of the fabric form an inverted V-shape, preventing wrinkles from forming due to inertia when traction between the pressing device 74 and the vertical device stops.

[0063] Compared with existing technologies, this invention, by setting up a pressing device 7, can perform vertical pressing, oblique pressing, and edge pressing of the fabric. Through multiple pressing processes, the fabric strength is greatly enhanced. Oblique pressing of the fabric allows excess adhesive in the middle of the fabric to be squeezed to the edges, preventing excessive adhesive from affecting the overall performance of the fabric. The oblique pressing device 76 squeezes excess adhesive to the edges, and the edge pressing device 77 presses the edges, resulting in high edge strength of the multi-layered fabric after pressing. Simultaneously, this invention achieves simultaneous conveying and pressing, resulting in high overall efficiency.
