[0003] The aforementioned fabric drying device has a problem: the amount of fabric dried in the chamber is relatively small, and the residence time is short, resulting in low drying efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drying device for textile fabrics that improves drying capacity and efficiency, in light of the current state of the technology.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problem is as follows: a drying device for textile fabrics, comprising a box and a receiving roller, wherein the bottom of the box is provided with support legs, and the receiving roller is disposed outside the box, characterized in that: the box is a sealed structure, a hollow cavity is formed in the middle of the box, a feeding assembly is disposed in the hollow cavity, and an inner roller group, a middle roller group and an outer roller group are arranged sequentially from the inside to the outside of the box, wherein the inner roller group includes a plurality of circumferentially arranged inner rollers, the middle roller group includes a plurality of circumferentially arranged middle rollers, and the outer roller group includes a plurality of circumferentially arranged outer rollers, and useful openings are formed on the cavity wall of the hollow cavity. The inner perforation through which the fabric passes is provided, and the outer wall of the box has an outer perforation for the fabric to pass through. The fabric passes through the inner perforation, first passing around each inner roller in sequence, then from the inner roller to the middle roller, then from the middle roller to the outer roller, then from the outer roller and out through the outer perforation of the box, and finally is wound onto the take-up roller. A hot air inlet is provided between the fabric and the inner wall of the hollow cavity for hot air input, and the hot air inlet is connected to an external hot air generator. An exhaust port is provided on the outer wall of the box near the outer perforation, and the exhaust port is connected to an external waste gas recovery device.

[0006] As an improvement, the feeding assembly includes a rotatable tripod with feeding rollers rotatably mounted at its three ends. A baffle is fixedly mounted in the hollow cavity near the inner perforation, with a first sewing hole on the baffle. A pressure plate is mounted opposite the baffle with a second sewing hole. A sewing needle is mounted on the outside of the baffle. The pressure plate is connected to a clamping cylinder. A gripping robot is mounted at the tripod.

[0007] In a further improvement, the receiving roller is rotatably mounted on the receiving frame, which is connected to a rotating cylinder that drives the receiving frame to rotate. A changing roller is rotatably mounted on the receiving frame, and a telescopic cylinder that pushes the changing roller to move radially is provided between the receiving frame and the changing roller. A cutter is provided outside the receiving frame, and the cutter is connected to a moving cylinder that drives the cutter to move back and forth.

[0008] Further improvements include: each inner roller is equipped with an inner pulley connected to an inner belt; each middle roller is equipped with a middle pulley connected to a middle belt; each outer roller is equipped with an outer pulley connected to an outer belt; an inner connecting belt is provided between one inner roller and one middle roller; an outer connecting belt is provided between one middle roller and one outer roller; and screw sections with opposite rotation directions are formed at both ends of each inner roller, middle roller, and outer roller, with nuts provided on the screw sections and rollers connected to the nuts.

[0009] Compared with the prior art, the advantages of this invention are as follows: During the drying process, the fabric is spirally conveyed outward from the center of the chamber, dividing the inner cavity of the chamber into multiple interconnected inner and outer layers. This maximizes the utilization of the internal space of the chamber and significantly extends the drying time and fabric length within the chamber, improving drying capacity and efficiency. Furthermore, during the drying process, the fabric conveying direction and the hot air conveying direction are consistent. As the hot air moves along the spiral-shaped chamber formed by the fabric, it can simultaneously dry both the front and back sides of the fabric. The hot air moves simultaneously with the fabric, ensuring that the higher the fabric's humidity, the higher the drying temperature, and as the fabric's humidity decreases, the drying temperature also decreases, achieving synchronization between fabric humidity and drying temperature and improving drying performance.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figures 1 to 5 As shown, the textile fabric drying device in this embodiment includes a box 1, support legs 11, feeding assembly 2, receiving roller 8, inner roller group, middle roller group, outer roller group, inner belt 91, middle belt 92, outer belt 93, inner connecting belt 45, outer connecting belt 56, left pull rope 31 and right pull rope 32.

[0017] The box 1 has a support leg 11 at the bottom, and a receiving roller 8 is located outside the box 1. The box 1 is a sealed structure, with a hollow cavity 101 formed in the middle. A feeding assembly 2 is installed inside the hollow cavity 101. From the inside to the outside, an inner roller group, a middle roller group, and an outer roller group are arranged in sequence inside the box 1. The inner roller group includes multiple circumferentially arranged inner rollers 4, the middle roller group includes multiple circumferentially arranged middle rollers 5, and the outer roller group includes multiple circumferentially arranged outer rollers 6. The cavity wall of the hollow cavity 101 has an inner perforation for the fabric 7 to pass through, and the outer wall of the box 1 has a perforation for the fabric 7 to pass through. The fabric 7 passes through the outer perforation and the inner perforation. First, it passes around each inner roller 4 in sequence, then from the inner roller 4 to the middle roller 5, then from the middle roller 5 to the outer roller 6, then from the outer roller 6 to the outer perforation of the housing 1, and finally is wound onto the take-up roller 8. A hot air inlet 13 for hot air input is provided between the fabric 7 and the inner wall of the hollow cavity 101. The hot air inlet 13 is connected to an external hot air generator. An exhaust port 12 is provided on the outer wall of the housing 1 near the outer perforation. The exhaust port 12 is connected to an external waste gas recovery device.

[0018] Furthermore, in order to achieve automatic material changing, such as Figure 4 As shown, the feeding assembly 2 includes a rotatable tripod 21, with feeding rollers 22 rotatably mounted at the three ends of the tripod 21. A baffle 222 is fixedly mounted in the hollow cavity 101 near the inner layer perforation. A first sewing hole 221 is provided on the baffle 222. A pressure plate 23 is provided opposite to the baffle 222. A second sewing hole 231 is provided on the pressure plate 23. A sewing needle 24 is provided on the outside of the baffle 222. The pressure plate 23 is connected to a clamping cylinder. A gripping robot 25 is provided at the tripod 21.

[0019] Furthermore, such as Figure 5 As shown, the take-up roller 8 is rotatably mounted on the take-up frame 81. The take-up frame 81 is connected to a rotating cylinder 84 that drives the take-up frame 81 to rotate. A changing roller 83 is rotatably mounted on the take-up frame 81. A telescopic cylinder 82 that pushes the changing roller 83 to move radially is provided between the take-up frame 81 and the changing roller 83. Specifically, a connecting plate is provided on the take-up frame 81. The changing roller 83 is rotatably mounted on the connecting plate. A winding motor is provided on the connecting plate. The winding motor is connected to the changing roller 83. A telescopic cylinder 82 is provided on the take-up frame 81. The output end of the telescopic cylinder 82 is connected to the connecting plate. A cutter is provided outside the take-up frame 81. The cutter is connected to a moving cylinder that drives the cutter to move back and forth.

[0020] When a new feed cylinder needs to be added, when the fabric on the feed roller 22 is nearly used up, a new feed cylinder is installed on the adjacent feed roller 22; the tripod 21 is rotated, the newly installed feed cylinder is at the top, the beginning of the fabric 7 hangs down, and the nearly used feed cylinder is rotated to the front and lower side; the robot arm 25 clamps the beginning of the fabric 7 and passes it through the pressure plate 23 and the baffle 222; the pressing cylinder is activated, and the pressure plate 23 presses the new fabric 7 and the nearly used fabric 7 together against the pressure plate 23 and the baffle 222. Between 22, the sewing needle 24 sews the two pieces of fabric 7 together; as drying proceeds, the new fabric 7 enters the box 1. When all the previously dried fabric 7 is rolled up on the take-up roller 8, the telescopic cylinder 82 extends. At the same time, the take-up frame 81 rotates, and the material changing roller 83 presses against the fabric 7. The material changing roller 83 rotates, rolling the fabric 7 onto the material changing roller 83; the cutter cuts the fabric 7 connected to the take-up roller 8, and the material cylinder on the take-up roller 8 is removed, thus completing the material changing.

[0021] In addition, another upper material exchange structure is disclosed in this embodiment of the invention, specifically, as follows: Figure 2 and 3 As shown, each inner roller 4 is equipped with an inner pulley 41, and an inner belt 91 is connected to the inner pulley 41. Each middle roller 5 is equipped with a middle pulley 51, and a middle belt 92 is connected to the middle pulley 52. ​​Each outer roller 6 is equipped with an outer pulley 61, and an outer belt 93 is connected to the outer pulley 61. An inner connecting belt 45 is provided between one of the inner rollers 4 and one of the middle rollers 5, and an outer connecting belt 56 is provided between one of the middle rollers 5 and one of the outer rollers 6. At both ends of each inner roller 4, both ends of each middle roller 5, and both ends of each outer roller 6, screw sections with opposite rotation directions are formed. Nuts are provided on the screw sections, and rollers 402 are connected to the nuts. A left pull cord 31 is provided on one side of the roller 402 along the direction of the fabric, and a right pull cord 32 is provided on the other side of the roller 402 along the direction of the fabric.

[0022] The inner belt 91 drives each inner layer roller 4 to rotate synchronously, the middle belt 92 drives each middle layer roller 5 to rotate synchronously, and the outer belt 93 drives each outer layer roller 6 to rotate synchronously. At the same time, the inner connecting belt 45 makes the inner layer roller 4 and the middle layer roller 5 have the same direction of rotation, and the outer connecting belt 56 makes the middle layer roller 5 and the outer layer roller 6 have the same direction of rotation. Thus, when the driving component drives one of the inner layer rollers 4 to rotate, the rollers 402 on the left and right sides of each roller shaft move closer or separate synchronously, so that the left pull rope 31 and the right pull rope 32 can move closer or separate along the roller shaft. Thus, when the material cylinder needs to be replaced, a connecting belt is connected to the front end of the fabric 7 of the new material cylinder. The left pull rope 31 and the right pull rope 32 are brought close to each other, and the first end of the connecting belt on the new material cylinder is connected to the left pull rope 31 and the right pull rope 32. When each roller rotates, the left pull rope 31 and the right pull rope 32 output the connecting belt on the new material cylinder to the outer perforation of the housing 1, and the connecting belt is wound up on the take-up roller 8. After that, the drive unit rotates in the opposite direction, and the left pull rope 31 and the right pull rope 32 separate from each other.

[0023] In summary, during the drying process, the fabric 7 of this invention is spirally conveyed outward from the middle of the box 1. The fabric 7 divides the inner cavity of the box 1 into multiple interconnected inner and outer layer structures, which maximizes the utilization of the internal space of the box 1. At the same time, it greatly extends the drying time and length of the fabric 7 in the box 1, improving the drying capacity and efficiency. In addition, during the drying process, the conveying direction of the fabric 7 is consistent with the conveying direction of the hot air. As the hot air moves along the spiral cavity formed by the fabric 7, it can simultaneously dry both the front and back sides of the fabric 7. The hot air moves simultaneously with the conveying of the fabric 7, ensuring that the higher the humidity of the fabric 7, the higher the drying temperature, and as the humidity of the fabric 7 decreases, the drying temperature also decreases, achieving synchronization between the humidity of the fabric 7 and the drying temperature, thus improving the drying performance.
