[0002] During the wet processing of textiles (such as dyeing, printing, washing, etc.), the fabrics will absorb a lot of water. If this water is not removed, the fabrics will not be able to be further processed or stored. Therefore, drying the textile fabrics is an important part of the textile processing process. After the textile fabrics are dried, there may be some areas with high humidity and uneven drying, which will affect the quality of the fabrics.

[0003] The Chinese patent with the announcement number CN117928199B discloses a textile fabric drying device for textile production and processing, including a machine tool, a re-drying structure, a clamping structure, a dust collecting structure, an auxiliary structure, a mounting structure, a lifting structure, a drying structure, a conveyor belt, a steam softening zone and a winding roller. The patent document conveys the fabric through the conveyor belt, the fabric is softened in the steam softening zone, and then dried and shaped in the drying structure, and the fabric coming out of the drying structure is detected by the re-drying structure. When the fabric is not completely dried, the winding roller is controlled to loosen one end of the wound fabric, and the fabric is sent back to the drying structure for drying through the clamping structure and the re-drying structure.

[0004] The above patent uses a clamping structure to pull the fabrics with poor drying degree back into the drying structure for secondary drying, which may cause the fabrics pulled back into the drying structure to stack, which is not only not conducive to the re-drying of the fabrics with poor drying degree, but also affects the normal drying of the fabrics stacked below, affecting the overall drying efficiency. In addition, the stacked fabrics may produce wrinkles, affecting the fabric quality.

[0005] Therefore, the art needs a textile drying device and a textile drying method to solve the above problems. Summary of the invention

[0015] During the conveying process of the cloth, fiber debris and the like will enter the upper space of the air outlet box through the air outlet holes on the upper end surface of the air outlet box. Through the cooperation of the movable door and the push plate, when the flip arm rotates into the drying box, the push plate moves from the right end to the left end of the flip arm and pushes open the movable door, thereby pushing the fiber debris and the like in the upper space to the material passing gap, and the fiber debris and the like fall from the material passing gap to the lower space, preventing these debris from being blown back onto the cloth when the cloth is dried for the second time.

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figures 1 to 8 As shown, a textile drying device of the present invention comprises a machine body 1, a drying box 2 and a winding roller 3 arranged on the machine body 1, the forward direction of the cloth in the drying box 2 is defined as the right direction, hot steam is introduced into the drying box 2, and the hot steam dries the cloth in the drying box 2, and a support assembly for supporting the cloth is arranged in the drying box 2, and the support assembly comprises support rollers 21 symmetrically arranged up and down, and a support space for the cloth to pass through is formed between the upper and lower support rollers 21. A discharge port is opened on the right side of the drying box 2, and a blocking curtain 22 is hung at the discharge port, and the dried cloth passes under the blocking curtain 22. The winding roller 3 is located on the right side of the drying box 2, and the dried cloth coming out of the drying box 2 is wound up.

[0033] like Figures 1 to 4 As shown, a turning mechanism is provided at the discharge port of the drying box 2, and the description is made with the turning mechanism in a horizontal state. The turning mechanism includes two turning arms 4 arranged front and back and two groups of clamping members arranged between the two turning arms 4. The left end of the turning arm 4 is rotatably connected to the drying box 2, and the two groups of clamping members are arranged at intervals along the left and right directions. The clamping members include two clamping rollers 41 symmetrically arranged up and down, and the two ends of the two clamping rollers 41 are respectively rotatably connected to the corresponding turning arms 4, and a gap is formed between the two clamping rollers 41 for the cloth to pass through. A driving member 1 for driving the turning arm 4 to rotate is provided on the drying box 2. As an example, the driving member 1 is a motor (not shown in the figure) fixedly mounted on the machine body 1, and the output shaft of the motor is fixedly connected to the turning arm 4 located on the front side.

[0034] A humidity sensor 5 is provided near the left end of the flip arm 4. As an example, the humidity sensor 5 is a contact humidity monitor. The humidity sensor 5 is located below the fabric to monitor the humidity of the fabric. When the humidity sensor 5 detects that the humidity of the fabric is greater than a preset value, the motor drives the flip arm 4 to flip upward into the drying box 2. The flip arm 4 drives the fabric to flip into the drying box 2 through two sets of clamping parts, so that the fabric that does not meet the drying degree can enter the drying box 2 for secondary drying. Moreover, due to the support of the two sets of clamping rollers 41, the fabric that re-enters the drying box 2 will not be stacked or contacted, so that the fabric can be dried quickly, the drying efficiency is improved, and the fabric will not be wrinkled, ensuring the quality of the fabric. In addition, during the flipping process of the flip arm 4, the winding roller 3 is continuously wound, which is not only conducive to the complete flipping of the fabric that does not meet the drying degree into the drying box 2, but also does not require shutdown operation, thereby improving work efficiency.

[0035] A heat conducting plate 23 is provided in the drying box 2. When the flip arm 4 flips into the drying box 2 until the cloth contacts the heat conducting plate 23, it stops rotating. The heat conducting plate 23 can transfer heat faster, so that the cloth dried for the second time can be dried quickly, thereby improving the drying efficiency. The flip arm 4 located at the rear side is connected to an air pipe (not shown in the figure) connected to the inside of the drying box 2, and a ventilation cavity (not shown in the figure) connected to the air pipe is provided in the flip arm 4, wherein the air pipe is a hose and will not affect the flipping of the flip arm 4. An air outlet box 6 located below the cloth is provided between the two groups of clamps, and an air outlet hole 61 is provided on the upper end surface of the air outlet box 6. The air outlet box 6 is connected to the flip arm 4 located at the rear side, and a valve assembly is provided on the flip arm 4. When the flip arm 4 is located outside the drying box 2, the valve assembly cuts off the connection between the air outlet box 6 and the ventilation cavity. When the flip arm 4 drives the cloth to fit on the heat conduction plate 23, the valve assembly connects the air outlet box 6 with the ventilation cavity, so that the hot steam in the drying box 2 is blown onto the cloth through the air outlet 61, preventing the heat conduction plate 23 from burning the cloth.

[0036] Since the cloth after drying may shrink and deform due to rapid cooling, in the present embodiment, an air outlet pipe 7 is provided between the two groups of clamps and is located above the cloth. An air outlet hole 61 is provided on the side of the air outlet pipe 7 facing away from the cloth. The air outlet pipe 7 is connected to the flip arm 4 located at the rear side. An avoidance groove 24 corresponding to the position of the air outlet pipe 7 is provided on the heat conducting plate 23. A partition 62 is provided in the air outlet box 6. The partition 62 divides the air outlet box 6 into an upper space 63 and a lower space 64. An air outlet hole 61 is also provided on the lower end surface of the air outlet box 6.

[0037] When the flip arm 4 is outside the drying box 2, the valve assembly connects the ventilation cavity with the outlet pipe 7 and the lower space 64 of the outlet box 6, and the hot steam in the drying box 2 enters the outlet pipe 7 and the lower space 64 of the outlet box 6, and is discharged from the outlet hole 61, which increases the temperature at the outlet of the drying box 2, so that the cloth gradually cools down after coming out of the drying box 2, avoiding the shrinkage and deformation of the cloth due to excessive cooling. When the flip arm 4 drives the cloth to fit on the heat conducting plate 23, the valve assembly cuts off the connection between the ventilation cavity and the outlet pipe 7 and the lower space 64.

[0038] like Figure 5 , Figure 6 and Figure 8 As shown, the valve assembly includes a connecting plate 8 and a driving assembly. The connecting plate 8 is slidably matched with the flip arm 4 located at the rear side in the vertical direction. The air outlet box 6 and the air outlet pipe 7 are respectively connected to the connecting plate 8. The connecting plate 8 is provided with a through hole 1 81 connected to the air outlet pipe 7, a through hole 2 82 connected to the lower space 64 of the air outlet box 6, and a through hole 3 83 connected to the upper space 63 of the air outlet box 6. The flip arm 4 is provided with an air outlet groove 1 42 and an air outlet groove 2 43 connected to the ventilation cavity. When the flip arm 4 is located outside the drying box 2, the driving assembly drives the connecting plate 8 to move until the through hole 1 81 is connected to the air outlet groove 1 42, and the through hole 2 82 is connected to the air outlet groove 2 43. When the flip arm 4 drives the cloth to fit on the heat conducting plate 23, the driving assembly drives the connecting plate 8 to move until the through hole 3 83 is connected to the air outlet groove 2 43.

[0039] The driving assembly includes a spring 1 45 and a slider 44. A slide groove 84 is provided on one side of the connecting plate 8 facing the rear flip arm 4. The slider 44 is vertically slidably connected in the slide groove 84 and elastically connected to the slide groove 84 through the spring 1 45. The rear flip arm 4 is fixedly connected to the slider 44. When the connecting plate 8 is not subjected to external force, the through hole 1 81 is connected to the air outlet groove 1 42, and the through hole 2 82 is connected to the air outlet groove 2 43. When the flip arm 4 rotates into the drying box 2 until the cloth is attached to the heat conducting plate 23, the connecting plate 8 cannot continue to rotate, and the flip arm 4 continues to rotate until the through hole 3 83 is connected to the air outlet groove 2 43.

[0040] like Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, during the conveying process of the cloth, fiber debris and the like will enter the upper space 63 of the air outlet box 6 through the air outlet hole 61 on the upper end surface of the air outlet box 6. Therefore, in order to prevent these debris from being blown back onto the cloth during the secondary drying of the cloth, in this embodiment, a material transfer gap connecting the upper space 63 and the lower space 64 is formed between the left end of the partition 62 and the air outlet box 6. A movable door 65 is provided near the material transfer gap in the upper space 63 of the air outlet box 6. The movable door 65 is rotatably connected to the air outlet box 6, and a torsion spring is provided at the rotating connection. When the movable door 65 is not subjected to external force, it is in a closed state. A push plate 66 is provided in the upper space 63 of the air outlet box 6 to slide in the left and right directions, and a driving member 2 for driving the push plate 66 to move left and right is provided on the machine body 1. A collecting frame 11 is provided below the flip mechanism of the machine body 1, and an electric control valve is connected to the air supply pipe.

[0041] When the flip arm 4 rotates into the drying box 2, the electric control valve disconnects the connection between the air pipe and the ventilation cavity, and the second driving member drives the push plate 66 to move from the right end to the left end of the flip arm 4, and pushes the movable door 65 to push the fiber debris in the upper space 63 to the material gap, and the fiber debris falls from the material gap to the lower space 64. When the upper space 63 of the air outlet box 6 is connected to the ventilation cavity, the electric control valve connects the air pipe with the ventilation cavity, so that the cloth attached to the heat conduction plate 23 is humidified by hot steam. When the flip arm 4 returns to a horizontal state and the lower space 64 is connected to the ventilation cavity, the hot steam blows these fiber debris from the air outlet hole 61 on the lower end surface of the air outlet box 6 into the collection frame 11.

[0042] The push plate 66 is elastically connected to the right end of the air outlet box 6 through a spring 2 67. The driving member 2 includes a guide plate 9 and an arc-shaped guide groove 91 opened on the guide plate 9. The guide plate 9 is fixedly connected to the body 1. One end of the push plate 66 extends into the arc-shaped guide groove 91. When the flip arm 4 rotates into the drying box 2, the push plate 66 moves along the arc-shaped guide groove 91.

[0043] A textile drying method, using the textile drying device in the above embodiment, the textile drying method comprises the following steps: The cloth is passed through the support rollers 21 in the drying box 2 and between the upper and lower clamping rollers 41 of the turning mechanism in sequence, and then connected to the winding roller 3; Hot steam is introduced into the drying box 2 to dry the fabric. When the fabric is rolled up by the winding roller 3, the humidity sensor 5 detects the humidity of the fabric coming out of the drying box 2. When the flip arm 4 is in a horizontal state, the air outlet pipe 7 and the lower space 64 of the air outlet box 6 are connected to the ventilation cavity, and the electric control valve connects the air delivery pipe with the ventilation cavity, and the hot steam in the drying box 2 is ejected from the air outlet pipe 7 and the air outlet hole 61 on the lower end surface of the air outlet box 6, thereby increasing the temperature on the right side of the material outlet of the drying box 2, so that the fabric is gradually cooled down; When the humidity sensor 5 detects that the humidity of the fabric is greater than a preset value, it transmits a signal to the driving member 1, and the driving member 1 drives the flip arm 4 to flip into the drying box 2. At the same time, the electric control valve disconnects the connection between the air supply pipe and the ventilation cavity. The flip arm 4 rotates into the drying box 2 until the fabric is attached to the heat conduction plate 23, and the connecting plate 8 cannot continue to rotate. The flip arm 4 continues to move relative to the connecting plate 8 until the upper space 63 of the air outlet box 6 is connected to the ventilation cavity. The electric control valve opens to connect the air supply pipe with the ventilation cavity, and the hot steam in the drying box 2 is sprayed onto the fabric from the air outlet hole 61 on the upper end surface of the air outlet box 6 to prevent the heat conduction plate 23 from burning the fabric. Afterwards, the electric control valve is controlled to disconnect the connection between the air supply pipe and the ventilation cavity, and the driving member drives the flip arm 4 to rotate and return to the horizontal state.
