Description

Technical Field

[0001] This invention belongs to the field of fabric processing technology, specifically relating to a production equipment for a three-dimensional three-layer fabric that is easy to wick away sweat and is breathable. Background Technology

[0002] Three-layer fabric is made by combining three different fabrics together, and it has different characteristics for use and is widely used.

[0003] Some existing technologies also include solutions for producing three-layer fabrics, such as a Chinese patent with publication number CN116100927A. This patent discloses a three-dimensional three-layer pipe fabric bonding device. This device can complete the bonding of three layers of fabric in one go, improving production efficiency and reducing production costs. First, the first pattern roller embosses the upper surface of the middle fabric, and then the second pattern roller embosses the lower surface of the second layer fabric and the middle fabric. After the layers are arched, they cover the bonding lines, making the fabric three-dimensional and thick, without cold spots, warm, and lightweight.

[0004] However, this patent requires embossing before hot pressing, which not only increases the structure required for embossing and makes the equipment more complex, but also takes a long time during the embossing process, further increasing the production time and delaying the production schedule. There is no extra time for shaping after embossing, and the embossed pattern may deform after hot pressing. Furthermore, glue may enter the arches formed by embossing, which may cause the arched part of the embossed pattern to stick to the second layer of fabric during the hot pressing process, resulting in fabric problems. Summary of the Invention

[0005] The purpose of this invention is to provide a production equipment for a three-dimensional three-layer fabric that is easy to wick away sweat and is breathable, in order to solve the problems mentioned in the background art.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A production device for a breathable and moisture-wicking three-layer fabric includes a first hot press roller and a second hot press roller for conveying a second layer of fabric and a third layer of fabric and pressing and bonding the two fabrics together. It also includes an adhesive coating mechanism for applying adhesive to the surfaces of the two fabrics before pressing and bonding. The first hot press roller has a hollow structure and several through holes connecting the cavities are opened along its circumference. A clamping and pulling assembly is provided inside the cavity of the first hot press roller. The clamping and pulling assembly is used to clamp the two fabrics intermittently and pull them through the through holes into the cavity of the first hot press roller, so that during spraying, uncoated areas are formed on the surfaces of the two fabrics at intervals. After pressing and bonding, a three-layer fabric with hollow interlayers is obtained.

[0008] Preferably, the clamping and pulling assembly includes a clamping mechanism and a suction mechanism. The clamping mechanism includes a connecting rod that passes through the first hot press roller. The connecting rod is provided with a telescopic component and a drive module for driving the connecting rod to rotate relative to the first hot press roller. The telescopic component is provided with a first plate and a second plate that are parallel to each other. Both the first plate and the second plate are threaded with several bolts. The bolts are connected to a clamping motor provided on the first plate. The clamping motor drives the bolts to rotate, which can change the distance between the first plate and the second plate.

[0009] The suction mechanism includes a suction nozzle located between the first plate and the second plate for sucking air from the two layers of fabric to change their shape. The suction nozzle is connected to the suction device through a pipe.

[0010] Preferably, the drive module includes a drive motor, and the output shaft end of the drive motor is provided with a roller that contacts the first hot press roller.

[0011] Preferably, the center of gravity of the clamping mechanism is lower than the axis height of the connecting rod, and the first hot press roller is provided with an adsorption element that stabilizes the clamping mechanism.

[0012] Preferably, the second plate is provided with a plurality of limiting holes along its length direction, and a clamping member is provided at the limiting hole for assisting in clamping the two layers of fabric. The clamping member can move at the limiting hole.

[0013] Preferably, the clamping member has a pointed tip, and the pointed tip contacts the second layer of fabric first when the second plate moves.

[0014] The beneficial effects of this invention are as follows:

[0015] This invention eliminates the need for additional and time-consuming processes such as embossing during production. The resulting fabric features air gaps and outward embossing, giving it a three-dimensional effect and excellent breathability and moisture-wicking properties. Attached Figure Description

[0022] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-5 As shown, a production device for a breathable and moisture-wicking three-layer fabric includes a first hot press roller 1 and a second hot press roller 2, as well as a gluing mechanism (in the prior art, a gluing roller) for applying adhesive to the fabric. The first hot press roller 1 and the second hot press roller 2 are parallel to each other and rotate under the drive of their respective drive mechanisms, pressing the fabric passing between them together. The first hot press roller 1 has a hollow structure, and has several through holes 3 connecting the cavities along its circumference.

[0025] A connecting rod 4 is rotatably installed inside the cavity of the No. 1 hot press roller 1, which passes through the No. 1 hot press roller 1. The connecting rod 4 is concentrically arranged with the No. 1 hot press roller 1. A telescopic component 5 is fixed on the connecting rod 4. The telescopic component 5 can be an electric push rod or a hydraulic cylinder.

[0026] A drive motor 11 is fixedly connected to the connecting rod 4, and a roller 12 that contacts the first hot press roller 1 is fixedly provided at the output shaft end of the drive motor 11. When the drive motor 11 drives the roller 12 to rotate, it synchronously drives the connecting rod 4 to rotate relative to the first hot press roller 1, thereby causing the telescopic member 5 to rotate inside the first hot press roller 1.

[0027] The telescopic end of the telescopic component 5 is fixedly equipped with a mounting plate, on which a first plate 6 is fixedly mounted, and a second plate 7 is movably mounted. Both the first plate 6 and the second plate 7 are threadedly connected with several bolts 8, which pass through both the first plate 6 and the second plate 7. A clamping motor 9 is fixedly mounted on the first plate 6, and the output shaft of the clamping motor 9 is fixedly connected to the bolts 8. The clamping motor 9 drives the bolts 8 to rotate, which changes the distance between the first plate 6 and the second plate 7.

[0028] The mounting plate has a through hole, and an air intake 14 is fixed at the through hole. The air intake 14 is connected to the air intake device through a pipe, which can be arranged to extend outward from the inside of the connecting rod 4.

[0029] It should be noted that the second layer fabric a is a composite fabric formed by combining two different fabrics. It was prepared before production, and the second layer fabric a was kept in a relaxed state on the first hot press roller 1 before the adhesive was applied. Before the adhesive was applied, the telescopic component 5 drove the first plate 6 and the second plate 7 to extend out from the through hole 3, and at the same time drove the air suction nozzle 14 to move. The suction generated by the air suction nozzle 14 acted on the second layer fabric a, causing the second layer fabric a to fold towards the air suction nozzle 14. Next, under the control of the clamping motor 9, the second plate 7 approaches the first plate 6, clamps the second layer of fabric a, and pulls it into the cavity, so that part of the second layer of fabric a cannot be coated with glue. The telescopic component 5 rotates with the first hot press roller 1. After the second layer of fabric a passes through the glue coating mechanism, the first plate 6 and the second plate 7 release the second layer of fabric a, and stick the glued second layer of fabric a and the third layer of fabric b together and pass them through the first hot press roller 1 and the second hot press roller 2. After the second layer of fabric a and the third layer of fabric b pass through the first hot press roller 1 and the second hot press roller 2, they form a three-dimensional three-layer fabric that is easy to sweat and breathable. This three-layer fabric has a hollow interlayer. During the process of clamping the two layers of fabric a, the telescopic component 5, the first plate 6, and the second plate 7 rotate with the first hot press roller 1. After the second plate 7 releases the fabric, the drive motor 11 drives the connecting rod 4 and the telescopic component 5 to rotate, rotating the telescopic component 5 to the next through hole 3, so that the telescopic component 5 can drive the second plate 7 to extend from the next through hole 3 to repeat the clamping action.

[0030] The third layer, fabric b, is made of embossed fabric. The embossed part is directly opposite the uncoated part of the second layer, fabric a. After hot pressing, the three layers of fabric have a three-dimensional embossed pattern on one side, which increases the contact area with air during use, allowing sweat to penetrate the fabric and dry more quickly.

[0031] Example 2

[0032] Unlike Embodiment 1, the second plate 7 has several limiting holes along its length. Clamping members for assisting in clamping the second layer of fabric a are provided at the limiting holes. The clamping members can move at the limiting holes and have pointed tips 10. Since it is easy to make mistakes when the plate clamps the fabric, by providing clamping members on the movable second plate 7, when the second plate 7 approaches the first plate 6, the pointed tips 10 first contact the second layer of fabric a. The pointed tips 10 lift the second layer of fabric a and squeeze it downward to create wrinkles, so that the second plate 7 clamps the wrinkled part of the second layer of fabric a onto the first plate 6. When the second plate 7 contacts the first plate 6, it squeezes the pointed tips 10 of the clamping members into the limiting holes. When the second layer of fabric a needs to be released, plate 7 moves away from plate 6. Plate 7 moves the clamping component at the through hole 3, and the tail of the clamping component contacts the through hole 3 of the first hot press roller 1, causing the tip 10 of the clamping component to move out of the limiting hole again, allowing the action to be repeated. There is a large friction between the clamping component and plate 7, so the second layer of fabric a will not move relative to plate 7 when it is lifted. Only when plate 6 and plate 7 are in contact, and plate 7 moves the clamping component to squeeze the first hot press roller 1, can the clamping component move.

[0033] Example 3

[0034] like Figure 5 As shown, unlike Embodiment 1, the total center of gravity of the telescopic component 5, the first plate 6, the second plate 7, and the suction nozzle 14 is lower than the axial height of the connecting rod 4. Furthermore, the first hot press roller 1 is equipped with an adsorption component 13 for stabilizing the telescopic component 5. The adsorption components 13 are equidistantly arranged along the circumference of the cavity of the first hot press roller 1 and correspond one-to-one with the through holes 3. After completing a single clamping operation, the clamping mechanism is in a free state. Due to its low center of gravity, the telescopic component 5 automatically rotates to a vertical position. When it rotates to the adsorption component 13, the magnetic attraction of the adsorption component 13 quickly stabilizes the telescopic component 5, allowing the second plate 7 to extend out of the first hot press roller 1 from the through hole 3, thus preventing the second plate 7 from colliding with the first hot press roller 1 during shaking.

[0035] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
