Description

Technical Field

[0001] This invention relates to the field of fabric processing technology, and in particular to a drying device for fabric coating spraying and its working method. Background Technology

[0002] In textile fabric processing, the drying process after coating spraying directly determines the adhesion, functional stability, and subsequent processing efficiency of the fabric coating. It is a crucial step in ensuring fabric quality, and the industry has extremely high requirements for the precision and reliability of drying equipment. Currently, most mainstream drying equipment adopts a fixed parameter mode, with preset heating temperature, drying time, and other parameters that remain unchanged throughout the drying process. The existing fixed-parameter drying method lacks real-time temperature monitoring capabilities in actual operation. It only indirectly infers the coating temperature by monitoring the ambient temperature of the drying chamber, which cannot accurately capture the dynamic changes in coating temperature caused by factors such as differences in fabric substrate, fluctuations in coating formula, and changes in operating speed. This can easily lead to coating cracking and yellowing due to excessively high temperatures, or incomplete drying and coating peeling due to excessively low temperatures. Furthermore, the drying adjustment method is singular and cannot dynamically adjust parameters according to the coating temperature. It relies solely on manually preset fixed values, which is difficult to adapt to the needs of different fabrics and coating processes, and cannot cope with sudden working conditions in production. This results in unstable drying quality, poor uniformity, and the fabric is prone to localized under-drying or over-drying.

[0003] Based on the above reasons, this invention proposes a drying device and its working method for fabric coating spraying, which can perform multi-form drying adjustment based on real-time temperature monitoring and ensure the drying quality of the fabric coating. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drying device for fabric coating spraying and its working method with advantages.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A drying device for fabric coating spraying includes a fixed frame, two of which are symmetrically arranged on the left and right sides. Each fixed frame has several fixed shells fixedly connected to it. A temperature measuring device is fixedly connected to each fixed shell. Each fixed shell has a mounting plate, and a through groove is opened on the top surface of the fixed shell. An infrared drying device is installed in the mounting plate. Two arc-shaped baffles are symmetrically installed in the mounting plate, one at the front and one at the back. The arc-shaped baffles are hollow and have several through holes on the side away from the mounting plate. An angle adjustment component is provided on the top surface of the mounting plate, and a translation component is provided on the side wall of the mounting plate. The lower sides of the two fixed frames are movably connected to the same mounting frame, and a spacing adjustment component is provided in the mounting frame.

[0006] Preferably, the angle adjustment component includes a fixing tube, which is fixedly connected to the top surface of the arc-shaped baffle and is configured to communicate with the inner cavity of the arc-shaped baffle. The top end of the fixing tube penetrates the top surface of the mounting plate, and a first gear is fixedly connected to the side wall of the fixing tube. Two meshing second gears are provided between the two first gears.

[0007] Preferably, the two second gears mesh with the two first gears respectively, and each of the second gears has a fixed shaft fixedly connected to the center of its side wall. The fixed shaft is movably connected to the mounting plate, and a first motor is fixedly connected to the top of one of the fixed shafts. A side plate is fixedly connected to the first motor, and the side plate is fixedly connected to the mounting plate.

[0008] Preferably, the translation component includes an electric push rod, which is fixedly connected to the fixed housing. A vertical plate is fixedly connected to the side wall of the electric push rod, and two horizontal bars are fixedly connected to the vertical plate. The end of the horizontal bar away from the vertical plate is fixedly connected to the mounting plate, and a sliding tube is sleeved on the side wall of the horizontal bar, which is fixedly connected to the fixed housing.

[0009] Preferably, the spacing adjustment component includes a threaded rod, which is threadedly connected to two fixed frames, and both ends of the threaded rod are movably connected to the mounting frame. The threaded rod has opposite thread directions on both sides symmetrical about the center of its side wall. One end of the threaded rod passes through the mounting frame and is fixedly connected to a second motor, which is fixedly connected to the mounting frame.

[0010] Preferably, the arc-shaped baffle is fitted with a movable shell on one side inside the mounting plate, and a plurality of springs are evenly distributed and fixedly connected inside the movable shell, with the other end of each spring fixedly connected to the arc-shaped baffle.

[0011] Preferably, the movable shell has a U-shaped cross-section, and a high-temperature resistant pad is fixedly connected to the side of the movable shell away from the arc-shaped baffle.

[0012] Preferably, a plurality of slide rails are evenly distributed and fixedly connected within the mounting frame, and a plurality of slide grooves are provided on the bottom surface of the fixed frame. The slide rails are respectively inserted into the slide grooves, and the slide rails are movably connected to the slide grooves.

[0013] Preferably, a connecting plate is fixedly connected between each of two adjacent fixed shells, and a plurality of temperature measuring devices are evenly distributed and fixedly connected to the connecting plate.

[0014] A method for operating a drying device for fabric coating spraying includes the following steps: S1: Install this drying device on the fabric production line so that the fabric after coating spraying can pass between the two fixed shells. According to the actual fabric thickness, the thickness of the fabric coating spraying, or the required drying temperature, start the second motor. The second motor drives the threaded rod to rotate. The threaded rod engages with the two fixed frames and moves on the slide rail, adjusting the two fixed shells to the specified distance from the fabric, thereby ensuring that the distance between the infrared drying device and the fabric is constant. Connect the fixed tube to the external negative pressure equipment. S2: Start the infrared drying device and control the speed of the fabric movement on the production line so that the infrared drying device can dry the coating sprayed on the fabric. During the drying process, the temperature of the fabric layer is measured in real time by the temperature measuring device and the measured data is transmitted to the external control module. Feedback on the drying effect of the fabric layer is given based on the real-time temperature data. S3: If uneven drying occurs in some areas of the fabric coating, start the first motor. The first motor drives the second gear to rotate through the fixed shaft. Through the transmission of the second gear, the first gears on both sides can rotate in opposite directions. The first gear drives the arc-shaped baffle to rotate through the fixed tube. The opening and closing angle of the arc-shaped baffle can control the drying area of ​​the infrared drying device to ensure the uniformity of drying of the fabric coating. S4: The electric push rod can also be driven and controlled to move the vertical plate, which in turn moves the horizontal bar. The horizontal bar moves the mounting plate within the fixed housing, which in turn moves the infrared drying device. This changes the distance between the infrared drying device and the fabric, thereby ensuring the drying effect of the infrared drying device on the fabric layer. S5: Furthermore, when the temperature of a certain area of ​​the fabric layer is too high, the external negative pressure device is activated. The operation of the external negative pressure device causes negative pressure to be generated in the inner cavity of the arc baffle, which can accelerate the rapid flow of air in the high-temperature area of ​​the fabric layer, thereby achieving a cooling effect on the fabric layer and further improving the drying effect of the fabric layer.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: This invention measures the temperature of the fabric layer in real time using a temperature measuring device and transmits the measured data to an external control module. Based on the real-time temperature data, feedback is provided on the drying effect of the fabric layer, thereby improving the drying quality of the fabric coating. This invention, by incorporating a spacing adjustment component, allows the fixed shells on both sides to be adjusted to a specified distance from the fabric, thereby ensuring a constant distance between the infrared drying device and the fabric, resulting in a stable drying effect. The angle adjustment component allows for adjustment of the opening and closing angle of the arc-shaped baffle, thus controlling the drying area of ​​the infrared drying device and ensuring uniform drying of the fabric coating. Furthermore, the translation component changes the distance between the infrared drying device and the fabric, ensuring the drying effect of the infrared drying device on the fabric layer. The combination of these three methods effectively ensures the quality of fabric layer drying. This invention connects a fixed tube to an external negative pressure device. When a certain area of ​​the fabric layer becomes too hot, the external negative pressure device is activated. The operation of the external negative pressure device generates negative pressure in the inner cavity of the arc-shaped baffle, which can accelerate the rapid flow of air in the high-temperature area of ​​the fabric layer, thereby achieving a cooling effect on the fabric layer and further improving the drying effect of the fabric layer.

Two meshing second gears 16 are provided between the two first gears 15. The two second gears 16 mesh with the two first gears 15 respectively.

The opening and closing angle of the arc baffle (7) can control the drying area of ​​the infrared drying device (6) to ensure the uniformity of drying of the fabric coating. S4: The electric push rod (20) can also be driven and controlled. The electric push rod (20) drives the vertical plate (21) to move, the vertical plate (21) drives the horizontal bar (22) to move, the horizontal bar (22) drives the mounting plate (4) to move in the cavity of the fixed shell (2), and the mounting plate (4) drives the infrared drying device (6) to move, thereby changing the distance between the infrared drying device (6) and the fabric, thus ensuring the drying effect of the infrared drying device (6) on the fabric layer; S5: Furthermore, when the temperature of a certain area of ​​the fabric layer is too high, the external negative pressure device is activated. The operation of the external negative pressure device causes the inner cavity of the arc baffle (7) to generate negative pressure, which can accelerate the rapid flow of air in the high temperature area of ​​the fabric layer, thereby achieving a cooling effect on the fabric layer and further improving the drying effect on the fabric layer.
