[0024] Please see Figures 1-4 This utility model provides a technical solution for a multifunctional textile drying device: A multifunctional textile drying device includes a base plate 1, an installation structure 2 symmetrically and fixedly connected to the upper end face of the base plate 1, an adjustment structure 3 provided in the inner cavity of the installation structure 2, a clamping structure 4 provided between two adjacent adjustment structures 3, a connecting structure 5 fixedly connected to the middle of the upper end face of the base plate 1, a blower structure 6 fixedly connected to the upper part of the inner cavity of the connecting structure 5, a heating structure 7 provided on the left side of the inner cavity of the connecting structure 5 below the blower structure 6, a guide structure 8 fixedly connected to the upper end face of the connecting structure 5, and a reciprocating structure 9 provided on the upper end face of the base plate 1 to the right of the connecting structure 5.

[0025] Furthermore, the mounting structure 2 includes a mounting plate 21 symmetrically fixedly connected to the upper end face of the base plate 1.

The adjustment structure 3 is installed and placed in use through the mounting structure 2 on the base plate 1, and the clamping structure 4 is limited and fixed by the mounting plate 21.

[0026] Furthermore, the adjustment structure 3 includes a limiting slide rod 31 fixedly connected to the middle of the inner cavity of the sliding groove 23. A spring 32 is movably sleeved on the outer surface of the limiting slide rod 31, and a slider is slidably connected to the outer surface of the limiting slide rod 31. The lower end face of the spring 32 is fixedly connected to the slider. A clamping structure 4 is provided between the two sliders. By adjusting the structure 3 on the mounting structure 2, the clamping structure 4 is installed and placed during use, and the extension and retraction of the spring 32 enables the clamping structure 4 to clamp textiles of different thicknesses.

[0027] Furthermore, the clamping structure 4 includes an upper clamping column 41 rotatably connected between the two sliders, and a lower clamping column 42 rotatably connected to the lower part of the inner cavity of the mounting frame 22.

Thus, through the conveying motor 43, the automatic continuous conveying of the textile in the drying device is realized without manual intervention, improving the automation level and efficiency of the entire drying process, and ensuring that the textile can pass through each functional area in sequence.

[0028] Furthermore, the connecting structure 5 includes a connecting frame 51 fixedly connected to the middle of the upper end face of the base plate 1.

It is the key power source for air drying and can ensure that there is air flow in all parts of the textile to achieve uniform air drying.

[0030] Furthermore, the heating structure 7 includes an electric heating tube 71 uniformly and fixedly connected to the left side of the inner cavity of the connecting frame 51. A connecting cable 72 is fixedly connected to the lower part of the left end face of the connecting frame 51.

The end of the connecting cable 72 away from the electric heating tube 71 is fixedly connected to the control module 73. The control module 73 is electrically connected to the electric heating tube 71 through the connecting cable 72. Through the heating structure 7 on the connecting structure 5, hot air is generated during operation to quickly dry the textile, which can effectively reduce the drying time of the textile and improve production efficiency. It is especially suitable for processing textiles with high humidity.

[0031] Furthermore, the guide structure 8 includes a guide frame 81 fixedly connected to the upper end face of the connecting frame 51. The inner cavity of the guide frame 81 is uniformly rotatably connected to a guide blade 82. The right end face of the guide frame 81 is uniformly rotatably connected to a crank connecting rod 83. The right end face of the guide blade 82 has a rotating shaft that passes through the guide frame 81 and is fixedly connected to the crank connecting rod 83. The right end face of the crank connecting rod 83 is provided with a reciprocating structure 9. Through the guide structure 8 on the connecting structure 5, the reciprocating structure 9 is installed and placed during use, and then the airflow direction is adjusted by the guide blade 82.

[0032] The reciprocating structure 9 includes a connecting crossbar 91 rotatably connected to the lower right end face of the guide vane 82. An adjusting ring 92 is fixedly connected to the middle of the lower end face of the connecting crossbar 91. An adjusting column is placed inside the adjusting ring 92. A reciprocating adjusting disc 93 is fixedly connected to the right end face of the adjusting column. A reciprocating motor 94 is fixedly connected to the middle right side of the upper end face of the base plate 1. The output end of the reciprocating motor 94 is fixedly connected to the reciprocating adjusting disc 93. The adjusting column is located on the left end face of the reciprocating adjusting disc 93. Through the reciprocating structure 9 on the base plate 1, the direction of the airflow output by the blower structure 6 can be flexibly adjusted during use to achieve air drying of the textile in the front and back directions, ensuring that the front and back parts of the textile are fully dried, and improving the comprehensiveness and uniformity of air drying.

[0033] Working principle: During operation, the textile is passed sequentially through the clamping structures 4 on both sides. Due to the thickness of the textile itself, the upper clamping column 41 moves upward, causing the sliders to slide towards each other, which in turn causes the spring 32 to contract. After the textile is placed, the spring 32 extends, causing the sliders and the upper clamping column 41 to move downward, thus fixing the textile. The conveyor motor 43 is then activated, causing its output end to rotate. This causes the lower clamping column 42 on the right side to rotate. Since the textile is located between the upper clamping column 41 and the lower clamping column 42, it moves to the right under the interaction of these two columns.

[0034] Simultaneously, the blower structure 6 is activated, causing the output end of the micro motor inside the rotating shaft 62 to rotate. This causes the fan blades 63 to rotate, thereby conveying air upwards from the connecting frame 51. Because the air inside the connecting frame 51 flows upwards, external air enters the connecting frame 51 through the air inlet slot 52. Furthermore, since the connecting frame 51 is divided by a partition, air on the left side of the connecting frame 51 is drawn into the left side of the connecting frame 51 through the air guide slot 53 when the blower structure 6 is operating.

[0035] When the blower structure 6 is operating, the heating structure 7 is simultaneously activated, turning on the control module 73. Therefore, the power supply within the control module 73 is transmitted to the heating element 71 via the connecting cable 72, causing the heating element 71 to start operating and heating the left side of the connecting frame 51. Thus, the blower structure 6 on the left blows hot air, rapidly drying the textile fabric. Subsequently, the cold air output from the blower structure 6 on the right cools the heated and dried textile fabric.

[0036] When it is necessary to adjust the airflow direction, the reciprocating structure 9 is activated, causing the output end of the reciprocating motor 94 to rotate, which in turn causes the reciprocating adjustment disc 93 to rotate. At this time, the adjustment ring 92 moves back and forth through the adjustment column. Since the adjustment ring 92 is fixedly connected to the connecting crossbar 91, the connecting crossbar 91 moves back and forth, so the crank connecting rod 83 rotates back and forth with the connecting shaft of the guide frame 81 as the center, thereby causing the guide vane 82 to rotate back and forth, thereby causing the airflow output by the blower structure 6 to tilt back and forth, thus achieving air drying of the textile in the front and back directions.

[0037] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
