[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] Example:
[0021] A drying device for fabric printing and dyeing, such as Figures 1 to 5 As shown, the device includes a drying chamber 1 and fabric inlets 2 and outlets 3 on both sides of the drying chamber 1. A ventilation pipe 4, communicating with the interior of the drying chamber 1, is welded to the top of the drying chamber 1. A fan is installed inside the ventilation pipe 4 via fastening bolts. A heating device 5 is installed inside the drying chamber 1 between the fabric inlets 2 and outlets 3. The heating device 5 is tubular, and its two ends are respectively welded with an input pipe 6 and an output pipe 7 communicating with it. Installation pipes 8 are installed on the outer periphery of both the input pipe 6 and the output pipe 7. The installation pipes 8 penetrate the side wall of the drying chamber 1 and extend to the outside of the drying chamber 1. The heating device 5 has a heating channel in the middle connecting the fabric inlets 2 and outlets 3. A conveying assembly 9 is installed inside the heating channel. The heating device 5 includes multiple heating coils 501 arranged coaxially in parallel. The heating elements 501 are arranged in a ring shape. The input pipe 6 and the output pipe 7 are welded to the outer peripheral walls of the two outermost heating rings 501. Multiple heating tubes 10 are integrally formed on the heating rings 501 and are arranged in a ring array, communicating with their interior. The multiple heating tubes 10 are installed on both sides of the multiple heating rings 501 located in the center and on the side of the two outermost heating rings 501 that are close to each other. The heating tubes 10 on the two adjacent heating rings 501 are arranged correspondingly. Flanges 11 arranged coaxially are welded on the heating tubes 10. The corresponding flanges 11 are fixed by bolts. The input pipe 6 and the output pipe 7 are both located inside the drying chamber 1, and the outer peripheral walls of the input pipe 6 and the output pipe 7 are both machined with external threads. The inner peripheral wall of the mounting pipe 8 is machined with internal threads that match the external threads.
[0022] The drying oven 1 includes a fixed frame 101 and a movable plate 102. Multiple support feet are welded to the bottom of the fixed frame 101. Two adjacent side walls of the fixed frame 101 are open. The heating device 5 and the conveying assembly 9 are both located inside the fixed frame 101. The mounting pipe 8 passes through the side wall of the fixed frame 101 and extends to the outside of the fixed frame 101. Through holes for fitting the mounting pipe 8 are provided on the side wall of the fixed frame 101. The ventilation pipe 4 is welded to the top of the fixed frame 101. The fabric inlet 2 is located on the fixed frame 101. The movable plate 102 has an L-shaped cross-section, and the fabric outlet 3 is located on the movable plate 102. The movable plate 102 is slidably mounted on the fixed frame 101 via a height adjustment assembly 12. The upper part is used to close the side wall of the opening of the fixed frame 101. The movable plate 102 is slidably installed on the fixed frame 101 in the vertical direction. The height adjustment component 12 includes a guide frame 121, a lead screw 122 and a threaded block 123. One side of the guide frame 121 is set with an opening and is welded to the side wall of the opening of the fixed frame 101. The lead screw 122 is set vertically and is rotatably connected to the inside of the guide frame 121. The lead screw 122 is rotatably connected to the inside of the guide frame 121 by a servo motor. The output end of the servo motor passes through the bottom of the guide frame 121 and is welded to the bottom end of the lead screw 122. The threaded block 123 is threadedly connected to the outer peripheral wall of the lead screw 122. The movable plate 102 is welded to one side of the threaded block 123.
[0023] The conveying assembly 9 includes a frame 901 and a plurality of guide rollers 902 rotatably connected within the frame 901 via a rotating shaft. A gap is formed between two adjacent guide rollers 902. The frame 901 and the guide rollers 902 are both located in the middle of the heating coil 501. One side of the frame 901 is welded to the inner wall of the fixed frame 101, and the other side of the frame 901 is in contact with the inner wall of the moving plate 102. A plurality of support bars 13 are welded to the inner wall of the fixed frame 101 near the inlet 2. The support bars 13 are used to abut against the bottom outer peripheral wall of the heating coil 501, and one end of the support bar 13 is in contact with the inner wall of the moving plate 102.
[0024] When the drying chamber 1 is in use, the fabric is transported into the drying chamber 1 through the fabric inlet 2. At this time, the moving plate 102 closes the side wall of the opening of the fixed frame 101. After the fabric is transported into the drying chamber 1, it is transported by the conveying assembly 9. At this time, the fabric is located in the heating channel in the middle of the heating device 5, and the fabric comes into contact with the guide roller 902, causing the guide roller 902 to rotate and guide the transport of the fabric. When the fabric is transported by the conveying assembly 9, hot steam can first be input into the mounting pipe 8 connected to the input pipe 6 and then into the input pipe 6. After that, the hot steam is input from the input pipe 6 to the outermost heating ring 501 connected to it. Because the heating pipe 10 is connected to the heating ring 501, and the heating pipes 10 on two adjacent heating rings 501 are installed by flange 11 and bolts, the hot steam is input from the heating ring 501 connected to the input pipe 6 through multiple heating pipes 10 into the adjacent heating rings 501, until the hot steam is input into multiple heating rings 501 in sequence. After that, the hot steam is output from the output pipe 7 and connected to the output pipe 7. The output of the mounting pipe 8, through repeated cycles, continuously heats the fabric transported by the conveying component 9. Because the heating ring 501 has a ring-shaped cross-section and multiple heating rings 501 are coaxially arranged in parallel within the fixed frame 101, while multiple heating tubes 10 are distributed in a ring array on the heating ring 501, the heating area is increased by the multiple heating rings 501 and heating tubes 10. The fabric is transported by multiple guide rollers 902, ensuring that the fabric is always in the middle position of the multiple heating rings 501, and always in the heating channel in the middle of the heating device 5, moving along the axial direction of the heating rings 501. This achieves uniform heating of the fabric, reduces uneven drying at different positions of the fabric, and improves the drying effect of the fabric. Furthermore, starting the fan and using the ventilation pipe 4 enables the exchange of hot and cold air inside and outside the drying chamber 1, achieving a cooling effect on the fabric. Afterward, the fabric is discharged from the drying chamber 1 through the fabric outlet 3 to complete the drying process. Multiple support bars 13 simultaneously support the bottom of the multiple heating rings 501, providing a support effect.
[0025] When the heating coil 501 is damaged and needs to be disassembled and replaced, first start the servo motor and drive the lead screw 122 to rotate clockwise. When the lead screw 122 rotates clockwise, it drives the threaded block 123 and the moving plate 102 connected to the threaded block 123 to move vertically upward until the moving plate 102 no longer closes the side wall of the opening of the fixed frame 101, so that one end of the support bar 13 and one side of the frame 901 do not abut against the inner side wall of the moving plate 102. At this time, the heating device 5 and the conveying assembly 9 located in the fixed frame 101 are exposed. Then, the mounting pipe 8 connected to the output pipe 7 can be rotated so that the external thread of the outer peripheral wall of the output pipe 7 does not match the internal thread of one of the mounting pipes 8. And the mounting pipe 8 connected to the input pipe 6 can be rotated so that the external thread of the input pipe 6 does not connect with the internal thread of the other mounting pipe 8. Then, the mounting pipe 8 is opened from the fixed frame 101. Remove it from the hole, and then remove the bolts on the flanges 11 of the heating tubes 10 of the two adjacent heating coils 501 so that the bolts are detached from the flanges 11 of the heating tubes 10 of the two adjacent heating coils 501. Then one of the heating coils 501 can be removed from the adjacent heating coil 501, and the removed heating coil 501 is moved along its axial direction until the heating coil 501 no longer contacts the support bar 13 and is removed from the fixed frame 101, so that one or more heating coils 501 can be removed and replaced without replacing the entire heating device 5. After the removed heating coil 501 is replaced, the servo motor is adjusted and the lead screw 122 is rotated counterclockwise. When the lead screw 122 rotates counterclockwise, it drives the threaded block 123 and the moving plate 102 to move downwards until the moving plate 102 closes the side wall of the opening of the fixed frame 101 again.
