[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1

[0022] Reference Figure 1-6 The first embodiment of the present invention provides a fabric drying device for garment production, including a main body 1, a control mechanism 2, a drying rack 3 and a hot air blower 4. The right surface of the control mechanism 2 is fixedly connected to the left surface of the main body 1. The drying rack 3 is disposed inside the main body 1. The hot air blower 4 is disposed inside the main body 1. An adjustment mechanism 5 is disposed on the left surface of the hot air blower 4. The adjustment mechanism 5 includes an adjustment plate 51, a first support column 52, a support frame 53, a through groove 54, and a stroke component 55. The right surface of the adjustment plate 51 is fixedly connected to the left surface of the hot air blower 4. The outer surface of the first support column 52 is rotatably connected to the inner wall of the adjustment plate 51 through a bearing. The support frame 53 is disposed on the outer surface of the first support column 52. The through groove 54 is opened on the surface of the support frame 53. The inner wall of the through groove 54 is fixedly connected to the upper and lower ends of the first support column 52. The stroke component 55 is disposed on the surface of the adjustment plate 51.

[0023] Specifically, this design enables large-area drying of clothing fabrics, saving a significant amount of time and manpower compared to traditional manual drying.

[0024] Furthermore, the clothing fabric is hung on the drying rack 3, and then moved longitudinally by the support frame 53. The support frame 53 can indirectly drive the hot air blower 4 to move longitudinally together. At the same time, the adjusting plate 51 swings laterally with the first support column 52 as the rotation center. When the adjusting plate 51 swings, it can drive the hot air blower 4 to swing together, so that the hot air blower 4 moves longitudinally and swings laterally at the same time. Example 2

[0025] In a second embodiment of the present invention, the stroke assembly 55 includes a stroke groove 551 and a stroke column 552. The stroke groove 551 is formed on the surface of the adjustment plate 51, and the outer surface of the stroke column 552 is slidably connected to the inner wall of the stroke groove 551. A reciprocating assembly 6 is provided on the upper end face of the stroke column 552. The reciprocating assembly 6 includes a stroke ring 61, a reciprocating column 62, a first gear 63, and a toothed plate 64. The outer surface of the stroke ring 61 is fixedly connected to the upper end face of the stroke column 552, and the outer surface of the reciprocating column 62 is slidably connected to the inner wall of the stroke ring 61. The right surface of the first gear 63 is fixedly connected to the left end face of the reciprocating column 62, and the outer surface of the toothed plate 64 and the outer surface of the first gear 63 are in a meshing relationship. A second support column 7 is provided on the inner wall of the first gear 63, and the outer surface of the second support column 7 is rotatably connected to the inner wall of the first gear 63 through a bearing. A sliding component 8 is provided on the right side of the second support column 7. There are two sliding components 8. The two sliding components 8 include a sliding rod 81 and a support member 82. The sliding rod 81 is fixedly connected to the front and rear sides of the stroke ring 61 at one end. The inner wall of the support member 82 is slidably connected to the outer surface of the sliding rod 81. A transmission assembly 9 is provided on the left surface of the support member 82. The transmission assembly 9 includes a support plate 91, a transmission block 92, a threaded rod 93, a motor 94, and a fixing member 95. The right surface of the support plate 91 is fixedly connected to the left surface of the support member 82 and the left end face of the second support column 7. The right surface of the transmission block 92 is fixedly connected to the left surface of the support plate 91. The outer surface of the threaded rod 93 is rotatably connected to the inner wall of the transmission block 92 through a thread. The output end of the motor 94 is fixedly connected to the upper end face of the threaded rod 93. There are two fixing members 95. The outer surface of the motor 94 is fixedly connected to the inner wall of the main body 1. The inner walls of the two fixing members 95 are rotatably connected to the outer surface of the threaded rod 93 through bearings. The left surface of the fixing member 95 is fixedly connected to the inner wall of the main body 1. The inner wall of the main body 1 is provided with a first sliding groove 10, and the inner wall of the first sliding groove 10 is slidably connected to the left surface of the transmission block 92.

[0026] Specifically, this design enables the drive adjustment plate 51 to perform a horizontal reciprocating swing effect.

[0027] Furthermore, the motor 94 rotates the threaded rod 93, which in turn drives the transmission block 92 to move longitudinally along the inner wall of the first slide groove 10. The transmission block 92 can drive the second support column 7, the sliding assembly 8, and the adjustment mechanism 5 to move longitudinally together via the support plate 91. The second support column 7 can drive the first gear 63 to mesh with the toothed plate 64, so that the first gear 63 drives the reciprocating column 62 to move in a circular trajectory. The reciprocating column 62 then presses against the inner wall of the stroke ring 61 and slides along the inner wall of the stroke ring 61. The stroke ring 61 then moves laterally back and forth along the inner wall of the support member 82 via the sliding rod 81. The stroke ring 61 can drive the stroke column 552, so that the stroke column 552 presses against the stroke groove 551 and slides along the inner wall of the stroke groove 551. At this time, the adjustment plate 51 is forced to oscillate back and forth around the first support column 52 as the center of rotation. Example 3

[0028] In the third embodiment of the present invention, a rotating assembly 11 is provided on the outer surface of the threaded rod 93. The rotating assembly 11 includes a second gear 111, a gear ring 112, and a second slide groove 113. The inner wall of the second gear 111 is fixedly connected to the outer surface of the threaded rod 93. The outer surface of the gear ring 112 and the outer surface of the second gear 111 are in a meshing relationship. The inner ring of the gear ring 112 is fixedly connected to the outer surface of the drying rack 3. The second slide groove 113 is opened on the inner wall of the main body 1. The inner wall of the second slide groove 113 is slidably connected to the upper surface of the transmission block 92.

[0029] Specifically, this design enables the drying rack 3 to move in a circular motion, which, in conjunction with the hot air blower, accelerates the drying efficiency of clothing fabrics.

[0030] Furthermore, the motor 94 drives the threaded rod 93 to rotate, which in turn drives the second gear 111 on the outer surface to rotate, so that the second gear 111 meshes with the gear ring 112. The gear ring 112 then rotates along the inner wall of the second slide groove 113. The rotation of the gear ring 112 can drive the drying rack 3 on the surface to move in a circle. Working principle:

[0031] The clothing fabric is hung on the drying rack 3. Then, the threaded rod 93 of the motor 94 rotates, which in turn drives the second gear 111 on the outer surface to rotate, causing the second gear 111 to mesh with the gear ring 112. The gear ring 112 then rotates along the inner wall of the second slide groove 113. The rotation of the gear ring 112 causes the drying rack 3 on the surface to move in a circular motion. At the same time, the rotation of the threaded rod 93 drives the transmission block 92 to move longitudinally along the inner wall of the first slide groove 10 through the thread. The transmission block 92 can drive the second support column 7, the sliding component 8, and the adjusting mechanism 5 to move longitudinally together through the support plate 91. The second support column 7 can drive the second support column 7, the sliding component 8, and the adjusting mechanism 5 to move longitudinally together. A gear 63 meshes with a toothed plate 64, causing the first gear 63 to drive the reciprocating column 62 to move in a circular trajectory. The reciprocating column 62 then presses against the inner wall of the stroke ring 61 and slides along the inner wall of the stroke ring 61. The stroke ring 61 then moves laterally back and forth along the inner wall of the support member 82 via the sliding rod 81. The stroke ring 61 can drive the stroke column 552, causing the stroke column 552 to press against the stroke groove 551 and slide along the inner wall of the stroke groove 551. At this time, the adjusting plate 51 is forced to swing back and forth around the first support column 52 as the center of rotation. When the adjusting plate 51 swings, it can drive the hot air blower 4 to swing together, causing the hot air blower 4 to move longitudinally and swing laterally at the same time.

[0032] In summary, by coordinating the adjustment mechanism 5, reciprocating component 6, second support column 7, sliding component 8, transmission component 9, first slide groove 10, and rotating component 11, the problem of long-term manual operation of hot air blowers for drying garment fabrics is solved. This not only leads to high labor intensity and fatigue for workers and low production efficiency, but also causes unstable drying quality due to differences in human judgment.
