[0008] A liquid control component is installed above the lifting plate, and a pressure block is fixedly connected to the bottom end of the lifting plate, and a reset cleaning component is transmission-connected to the bottom of the pressure block;

[0009] The reset cleaning assembly includes a reset plate, the reset plate penetrates and slides on the outer wall of the screw rod, the bottom end of the reset plate is fixedly connected to a reset spring, and the bottom end of the reset spring is fixedly connected to the inner bottom wall of the body, the reset plate is internally rotatably connected to a tension sleeve, the outer wall of the tension sleeve is abutted and connected to a turntable, and the inner wall of the tension sleeve is abutted and installed with a rotating rod, the rotating rod is rotatably connected to the inner bottom wall of the body, and the center of the rotating rod coincides with the center of the turntable;

[0010] One side of the rotating rod is connected to a vertical rod in a transmission manner, the vertical rod is rotatably connected to the inner bottom wall of the machine body, and the vertical rod and the rotating rod are arranged in parallel, and one side of the vertical rod is connected to a first bevel gear in a transmission manner, and the first bevel gear is rotatably connected to the inner bottom wall of the machine body;

[0011] The surface of the first bevel gear is meshedly connected with a second bevel gear, the second bevel gear is rotatably connected to the inside of the machine body, the rear end of the second bevel gear is fixedly connected with a fan blade, the fan blade is rotatably connected to the inside of the machine body, and a side plate is provided on one side of the fan blade, and the side plate is fixedly installed inside the machine body;

[0012] A bottom block is fixedly connected between the two side plates, the bottom block is arranged parallel to the lower side of the temperature transfer plate, and a plurality of test plates are fixedly connected to the surface of the bottom block, the plurality of test plates are arranged parallel to the lower side of the pressing plate;

[0013] The surface of the bottom block is slidably connected with a cleaning block, the surface of the cleaning block is rotatably connected with a crank rod, and the other end of the crank rod is rotatably connected with the surface of a rotating disk.

[0014] The working principle of the present invention is as follows: During detection, the driving motor drives the fan blades to rotate. When there is no limiting effect above the reset plate, the reset plate moves upward under the elastic action of the reset spring, causing the reset plate to drive the tensioning sleeve inside to connect the turntable and the rotating rod, so that the rotating rod can drive the turntable to rotate. At the same time, when the driving motor is powered on, the fan blades blow air tightly against the surface of the bottom block on one side of the side plate. Through the transmission connection between the first bevel gear and the second bevel gear, and under the transmission connection between the first bevel gear and the vertical rod, the rotating rod drives the turntable to rotate synchronously, causing the turntable to drive the cleaning block to perform telescopic movement through the crank rod. With the cleaning block slidably connected to the inside of the side plate, the cleaning block wipes the surface of the bottom block, avoiding the influence of residues on the surface of the bottom block on the detection accuracy, facilitating the user to accurately lay the test material on the surface of the bottom block. After the surface of the bottom block is wiped clean, the fan blades stop rotating, and the composite fabric is laid on the surface of the bottom block. At the same time, the bidirectional motor drives the screw rod to rotate, causing the screw rod to drive the lifting plate to move downward. A positioning cover and a pressing plate are correspondingly arranged above the test plate, so that the fixing plate drives each corresponding pressing plate at the bottom to be accurately pressed against the test plate, ensuring that each pressing plate is accurately pressed above each test plate, facilitating the accurate detection of the humidity sensor inside the test plate. When the fixing plate moves downward, the pressing block at the bottom of the lifting plate and the temperature transfer plate at the bottom of the fixing plate descend synchronously, causing the pressing block and the temperature transfer plate to squeeze the reset plate from above, so that the reset plate drives the tensioning sleeve to disconnect the turntable and the rotating rod, facilitating the subsequent rotation of the fan blades without interfering with the turntable. At the same time, to ensure the detection accuracy, the detection environment is adjusted according to the detection requirements of the composite material. When the electric push rod drives the connecting plate, when the electric push rod is powered on, through the meshing connection between the toothed plate and the gear column, the gear column drives the horizontal racks on both sides to perform synchronous telescopic movement. With the upper pressing plate fixedly connected to the bottom of the horizontal rack, the horizontal rack drives the upper pressing plate at the bottom to switch between the heating plate, the cooling plate and the interval, facilitating the temperature change switching inside the fan blades, realizing the synchronous detection of the composite material in different environments. At the same time, when the lifting plate descends, by rotatably connecting the transmission rod inside the lifting plate, the lifting plate drives the transmission rod at the bottom to be inserted above the vertical rod, so that the fan blades drive the transmission rod to rotate synchronously through the vertical rod during rotation. At the same time, by connecting the bottom ends of the liquid storage cylinders to the fixed pipes through hoses with each unequal flow control hole, the liquid supply amounts above each test plate are different, making the liquid output amounts on the surface of the composite material synchronous and equidistant, facilitating the curve liquid supply detection of the composite material in the same environment, ensuring the accurate dynamic detection of the composite material in the same environment, and greatly improving the detection efficiency and detection accuracy.

[0015] A first synchronous pulley is fixedly connected to the outer wall of the rotating rod, and the other end of the first synchronous pulley is fixedly connected to a vertical rod;

[0016] The outer wall of the vertical rod is fixedly connected with a second synchronous pulley, and the other end of the second synchronous pulley is fixedly connected with a first bevel gear.

[0017] With the above structure, through the setting of the first synchronous pulley and the second synchronous pulley, when the driving motor drives the fan blade to rotate with the driving motor output end fixedly connected to one end of the fan blade, the rotating rod drives the turntable to rotate through transmission. The transmission is simple and convenient, and the maintenance cost is low. It simultaneously realizes blowing and wiping the surface of the bottom block, ensuring the objectivity and accuracy of the detection.

[0018] Both ends of the cleaning block are slidably connected inside the side plate, and a groove for accommodating the sliding of the cleaning block is provided on the inner side of the side plate. The side plates are vertically arranged on both sides of the bottom block, and a temperature control unit is arranged inside the side plates.

[0019] With the above structure, two cleaning blocks are symmetrically arranged between the two side plates, so that the two cleaning blocks perform telescopic wiping on the surface of the bottom block through telescoping, ensuring the accuracy of the test board before each detection. Moreover, through the synchronous blowing of the fan blade, the surface of the test board is kept dry, avoiding the influence of the humidity on the surface of the test board on the test accuracy.

[0020] The environment switching component includes an electric push rod. The electric push rod is fixedly connected to the top end of the fixed plate. The output end of the electric push rod is fixedly connected with a connecting plate, and a toothed plate is fixedly connected to the bottom end of the connecting plate. The toothed plate is slidably connected to the inner wall of the fixed plate. The outer wall of the toothed plate is meshed with a gear column, and a movable rod is fixedly connected to the inside of the gear column. The movable rod is rotatably connected to the inside of the fixed plate;

[0021] Two horizontal racks are symmetrically meshed with the outer wall of the gear column. The horizontal racks are slidably connected to the inside of the fixed plate, and upper pressing plates are fixedly connected to the bottom ends of the two horizontal racks. A temperature control unit is arranged below the upper pressing plates.

[0022] With the above structure, by fixedly installing the connecting plate at the output end of the electric push rod, the electric push rod can drive the toothed plate to move through the connecting plate. Under the meshing action of the toothed plate and the gear column, the toothed plate can realize the synchronous transmission of the two horizontal racks. Driven by a single set of electric push rods, the structure is simple and has good balance, ensuring the accuracy and synchronism of the position adjustment and switching of the upper pressing plates on both sides.

[0023] The bottom end of the horizontal rack is fixedly connected with a slider, and the slider is slidably connected to the inner bottom wall of the fixed plate;

[0024] A through groove for accommodating the movement of the upper pressing plate is provided at the bottom end of the fixed plate;

[0025] Horizontal racks are fixedly connected above both ends of the upper pressing plate, and the two upper pressing plates are arranged in parallel.

[0026] With the above structure, through the setting of the horizontal rack, the rotation of the gear column drives two symmetrically meshing horizontal racks. With the horizontal racks fixedly connected to both ends of the upper pressing plate, the rotation of the two gear columns can adjust the position of the upper pressing plate to balance, enabling the upper pressing plate to change and control the temperature of the environment between the heating plate, the cooling plate, or the heating plate and the cooling plate. The temperature switching on one side of the fan blade of the heating plate and the cooling plate is realized, allowing the fan blade to blow air of different temperatures on the surface of the bottom block, facilitating the user to simulate the drying test of composite fabrics in different environments with higher accuracy.

[0027] The temperature control unit includes a heating plate, which is slidably connected to the inner wall of the side plate. The inner wall of the side plate is also slidably connected with a cooling plate, which is arranged parallel to the heating plate, and the distance between the cooling plate and the heating plate is greater than the thickness of the upper pressing plate, and the thickness of the upper pressing plate is greater than the thicknesses of the cooling plate and the heating plate.

[0028] The bottom ends of the cooling plate and the heating plate are both fixedly connected with telescopic springs, and the bottom ends of the telescopic springs are fixedly connected to the inner bottom wall of the side plate.

[0029] With the above structure, under the action of the heating plate and the cooling plate slidably connected inside the side plate, by rotatably connecting a fan blade on the other side of the side plate, the user can adjust the blowing temperature by switching between the heating plate and the cooling plate. Moreover, by fixedly connecting telescopic springs to the bottom ends of the heating plate and the cooling plate, the heating plate and the cooling plate are located above the side plate by the elastic action of the telescopic springs under normal conditions, realizing the normal temperature detection of the fan blade. At the same time, in order to ensure the air outlet effect of the fan blade, ventilation holes are provided on the inner side of the side plate to facilitate precise guiding of the fan blade and ensure the accuracy of the air blown by the fan blade on the surface of the bottom block.

[0030] The liquid control component includes a bracket, which is fixedly connected to the surface of the lifting plate. The top end of the bracket is fixedly connected with a liquid storage cylinder, and a plurality of flow control holes are annularly and non-equidistantly arranged at the bottom of the liquid storage cylinder. A baffle is fitted on the surface of the flow control hole, and the bottom end of the baffle is fixedly connected with a transmission rod, which is rotatably connected inside the lifting plate, and the bottom end of the transmission rod drives a vertical rod.

[0031] The multiple flow control holes are arranged in a non-equidistant and annular shape, and the multiple flow control holes are correspondingly arranged with multiple fixed pipes, and a hose is fixedly installed between each flow control hole and the corresponding fixed pipe.

[0032] With the above structure, by arranging the multiple flow control holes in an equidistant and variable-diameter manner, the synchronous and equidistant liquid output on the surface of the composite material is achieved, facilitating the dynamic detection of the composite material in the same environment, greatly improving the detection efficiency, ensuring the environmental synchronism under multiple dynamic detections, and guaranteeing the accuracy and objectivity of the drying detection of the composite material.

[0033] The bottom end of the transmission rod has a polygonal structure, and a polygonal slot is correspondingly opened at the top end of the vertical rod with respect to the polygon.

[0034] A through hole is opened inside the baffle.

[0035] With the above structure, by opening a polygonal slot at the top end of the vertical rod and under the action of the polygonal structure corresponding to the bottom end of the transmission rod, when the lead screw drives the lifting plate to move downward, the lifting plate synchronously drives the transmission rod to be inserted into the vertical rod, realizing the transmission effect that the vertical rod drives the transmission rod when rotating, facilitating the transmission rod to drive the baffle to rotate and discharge liquid on the surface of the flow control hole, so that the liquid can be discharged in turn through the flow control hole.

[0036] A drying property testing method for a composite fabric, applied to the drying property testing device for the composite fabric described above, includes the following steps:

[0037] S1. Preparation before testing: Drive the fan blade to rotate through the drive motor. With the setting of the reset cleaning component, the reset plate moves upward to drive the turntable to rotate, and the turntable drives the cleaning block to wipe on the surface of the bottom block through the crank rod, avoiding the detection accuracy of the residues on the surface of the bottom block and facilitating the user to accurately lay the test material on the surface of the bottom block.

[0038] S2. Fabric positioning: After laying the composite fabric on the surface of the bottom block, by correspondingly setting a positioning cover and a pressing plate above the test plate, when the lead screw drives the fixed plate to move downward through the lifting plate, the fixed plate drives each corresponding pressing plate at the bottom end to be accurately pressed against the test plate.

[0039] S3. Environmental temperature change switching: When the fixed plate moves downward, adjust the detection environment according to the detection requirements. Under the action of the electric push rod driving the connecting plate, the toothed plate drives the gear column to rotate, so that the gear column synchronously drives the horizontal racks on both sides to expand and contract synchronously, and the horizontal racks drive the upper pressing plate at the bottom end to switch between the heating plate, the cooling plate and the interval, facilitating the temperature change switching inside the fan blade.

[0040] S4. Water outlet test: After the liquid control component changes the temperature of the environment, the lifting plate drives the transmission rod at the bottom to be inserted above the vertical rod, and the fan blade drives the transmission rod to rotate synchronously when rotating. By connecting each unequal-diameter flow control hole at the bottom end of the liquid storage cylinder to the fixed pipe, the liquid supply amount above each test plate is different, facilitating dynamic detection under the same environment.

[0041] S5. Reset and cleaning: After the detection is completed, the lifting plate rises and resets, so that the reset plate is not limited, and thus the reset plate moves upward and the crank rod moves, and the cleaning block wipes the surface of the bottom block after the detection is completed, facilitating the next detection.

[0042] Compared with the prior art, the drying property testing device and testing method of the composite fabric of the present invention have the following advantages:

[0043] 1. In the present invention, by arranging the lifting plate and the fixing plate to lift above the bottom block, when the fixing plate rises, the reset plate is not limited, realizing the transmission effect of the rotating rod and the turntable when the bottom block is opened, facilitating the rotating rod to drive the cleaning block to wipe the surface of the bottom block, achieving the reset before each detection, which is beneficial to improving the detection accuracy and objectivity. At the same time, by arranging the transmission rod and the pressing block at the bottom of the lifting plate, when the lifting plate drives the fixing plate to detect the composite fabric, the reset and liquid control of the cleaning block can be realized, ensuring the detection effect of the test material on the surface of the bottom block, avoiding the interference of the cleaning block, having good synchronization and high integration degree, and realizing the dynamic drying property detection of the composite fabric by the user in different temperature environments, ensuring the objectivity and accuracy of the detection data.

[0044] 2. In the present invention, through the setting of the environment switching component, the electric push rod can drive and adjust the toothed plate, and under the meshing action of the gear column, the horizontal rack synchronously drives the upper pressing plate to switch positions, so that the upper pressing plate squeezes the cooling plate, the heating plate and the space interval above to realize the temperature change of the cooling plate and the heating plate on one side of the fan blade, facilitating the simulation of different temperature environments outside the heat transfer cover, realizing the dynamic detection of the composite fabric. Moreover, through the setting of multiple detection plates, the composite fabric can be detected in the same environment at multiple positions at one time, facilitating the analysis and comparison of the detection data, greatly improving the detection efficiency and detection accuracy.

[0045] 3. In the present invention, under the action of the reset cleaning component, multiple reset plates can be driven to lift through the pressing block, realizing the flexible connection between the reset plate and the turntable and the rotating rod, facilitating the switching of the working state of the turntable, ensuring the sliding effect and telescopic quality of the cleaning block, and realizing the data reset on the surface of the bottom block, avoiding the influence of the bottom block environment on the detection accuracy and objectivity, and ensuring the detection quality of the composite fabric.

[0046] 4. In the present invention, through the setting of the liquid control component, under the action of the corresponding connection of multiple liquid control holes and multiple fixed pipes through hoses, each liquid control hole can accurately supply variable flow liquid to the bottom of the pressing plate through the fixed pipe. Moreover, under the transmission action of the transmission rod and the vertical rod, the transmission rod drives the baffle to rotate and discharge liquid on the surface of the liquid control hole. By arranging multiple liquid control holes at equal intervals with variable diameters, the synchronous and equidistant liquid discharge amount of the liquid on the surface of the composite material is realized, facilitating the dynamic detection of the composite material in the same environment, greatly improving the detection efficiency, ensuring the environmental synchronization under multiple dynamic detections, and ensuring the accuracy and objectivity of the drying property detection of the composite material.

The toothed plate 37 is slidably connected to the inner wall of the fixed plate 7. The outer wall of the toothed plate 37 is meshed with a gear column 32. The inside of the gear column 32 is fixedly connected with a movable rod 33. The movable rod 33 is rotatably connected to the inside of the fixed plate 7. Through such a setting, the connecting plate 31 is fixedly installed at the output end of the electric push rod 30, so that the electric push rod 30 can drive the toothed plate 37 to move through the connecting plate 31. Under the meshing action of the toothed plate 37 and the gear column 32, the toothed plate 37 can realize the synchronous transmission of two horizontal toothed bars 34. Driven by a single group of electric push rods 30, the structure is simple and the balance is good, ensuring the accuracy and synchronism of the position adjustment and switching of the upper pressing plates 35 on both sides. To ensure the synchronous effect of the gear column 32, two horizontal toothed bars 34 are symmetrically meshed and connected to the outer wall of the gear column 32. The horizontal toothed bars 34 are slidably connected to the inside of the fixed plate 7. Specifically, the bottom end of the horizontal toothed bar 34 is fixedly connected with a slider 36. The slider 36 is slidably connected to the inner bottom wall of the fixed plate 7. Under the action of the horizontal toothed bar 34, the gear column 32 realizes the transmission of two symmetrically meshed horizontal toothed bars 34 when rotating. Under the action of the horizontal toothed bars 34 fixedly connected to both ends of the upper pressing plate 35, the two gear columns 32 can realize the balanced position adjustment of the upper pressing plate 35 when rotating, so that the upper pressing plate 35 can change the temperature control of the environment between the heating plate 38, the cooling plate 39 or the heating plate 38 and the cooling plate 39, realizing the temperature switching of the heating plate 38 and the cooling plate 39 on one side of the fan blade 23, so that the fan blade 23 blows air at different temperatures on the surface of the bottom block 26, facilitating the user to simulate the drying detection of composite fabrics under different environments with higher accuracy. And to ensure the balance of the position adjustment of the upper pressing plate 35, horizontal toothed bars 34 are fixedly connected above both ends of the upper pressing plate 35, and upper pressing plates 35 are fixedly connected to the bottom ends of the two horizontal toothed bars 34. The two upper pressing plates 35 are arranged in parallel. At the same time, a through groove for accommodating the movement of the upper pressing plate 35 is opened at the bottom end of the fixed plate 7.

[0068] Further, in order to achieve the transmission after the lifting plate 5 drives the upper pressure plate 35 to descend, a temperature adjustment unit is provided below the upper pressure plate 35. Among them, the temperature adjustment unit includes a heating plate 38. The heating plate 38 is slidably connected to the inner wall of the side plate 25. A cooling plate 39 is also slidably connected to the inner wall of the side plate 25. The cooling plate 39 is arranged parallel to the heating plate 38, and the distance between the cooling plate 39 and the heating plate 38 is greater than the thickness of the upper pressure plate 35, and the thickness of the upper pressure plate 35 is greater than the thicknesses of the cooling plate 39 and the heating plate 38. The bottom ends of the cooling plate 39 and the heating plate 38 are fixedly connected with telescopic springs 40, and the bottom ends of the telescopic springs 40 are fixedly connected to the inner bottom wall of the side plate 25. Through such a setting, under the action of slidably connecting the heating plate 38 and the cooling plate 39 inside the side plate 25, by rotatably connecting a fan blade 23 on the other side of the side plate 25, the user can adjust the blowing temperature by switching between the heating plate 38 and the cooling plate 39. Moreover, by fixedly connecting the telescopic springs 40 to the bottom ends of the heating plate 38 and the cooling plate 39, the heating plate 38 and the cooling plate 39 are located above the side plate 25 through the elastic action of the telescopic springs 40 under normal conditions, realizing the normal-temperature detection of the fan blade 23 under normal conditions. At the same time, in order to ensure the air outlet effect of the fan blade 23, ventilation holes are opened on the inner side of the side plate 25, which is convenient for accurately guiding the fan blade 23 and ensuring the blowing accuracy of the fan blade 23 on the surface of the bottom block 26.

[0069] The liquid control assembly includes a bracket 43, which is fixedly connected to the surface of the lifting plate 5. The top of the bracket 43 is fixedly connected with a liquid storage cylinder 42, and a plurality of flow control holes 44 are annularly formed at the bottom of the liquid storage cylinder 42. A baffle 45 is fitted on the surface of the flow control hole 44. A through hole 46 is formed inside the baffle 45, and a transmission rod 41 is fixedly connected to the bottom end of the baffle 45. The transmission rod 41 is rotatably connected inside the lifting plate 5, and a vertical rod 19 is driven at the bottom end of the transmission rod 41. Specifically, the bottom end of the transmission rod 41 has a polygonal structure, and a polygonal slot is correspondingly formed at the top end of the vertical rod 19. By forming a polygonal slot at the top end of the vertical rod 19 and under the action of the corresponding polygonal structure at the bottom end of the transmission rod 41, when the screw rod 2 drives the lifting plate 5 to move downward, the lifting plate 5 synchronously drives the transmission rod 41 to be inserted into the vertical rod 19, realizing the transmission effect that the vertical rod 19 drives the transmission rod 41 when rotating. At the same time, the plurality of flow control holes 44 are arranged in a non-uniform diameter in a ring shape, and the plurality of flow control holes 44 are correspondingly arranged with the plurality of fixed pipes 8. A hose is fixedly installed between each flow control hole 44 and the corresponding fixed pipe 8. The transmission rod 41 drives the baffle 45 to rotate and discharge liquid on the surface of the flow control hole 44. When the plurality of flow control holes 44 are arranged in an equidistant variable diameter, under the action of the hose, each flow control hole 44 supplies liquid to the pressing plate 9 through the fixed pipe 8, so that the liquid discharge amount on the surface of the composite material is synchronous and equidistant, which is convenient for dynamically detecting the composite material in the same environment, greatly improving the detection efficiency, ensuring the environmental synchronization under multiple dynamic detections, and ensuring the accuracy and objectivity of the dryness detection of the composite material, thus making the liquid...

[0070] Working principle of this production equipment: During detection, the driving motor 24 drives the fan blade 23 to rotate. When there is no limiting effect above the reset plate 13, the reset plate 13 moves upward under the elastic action of the reset spring 14, causing the reset plate 13 to drive the internal tensioning sleeve 15 to connect the turntable 16 and the rotating rod 17, so that the rotating rod 17 can drive the turntable 16 to rotate. At the same time, when the driving motor 24 is powered on, the fan blade 23 blows air tightly against the surface of the bottom block 26 on one side of the side plate 25. Through the transmission connection between the first bevel gear 21 and the second bevel gear 22, and under the transmission connection between the first bevel gear 21 and the vertical rod 19, the rotating rod 17 synchronously drives the turntable 16 to rotate, causing the turntable 16 to drive the cleaning block 28 to perform telescopic movement through the crank rod 29. With the cleaning block 28 slidingly connected to the inside of the side plate 25, the cleaning block 28 wipes the surface of the bottom block 26, avoiding the detection accuracy affected by the residues on the surface of the bottom block 26 and facilitating the user to accurately lay the test material on the surface of the bottom block 26. After the surface of the bottom block 26 is wiped clean, the fan blade 23 stops rotating, and the composite fabric is laid on the surface of the bottom block 26. At the same time, the bidirectional motor 3 drives the lead screw 2 to rotate, causing the lead screw 2 to drive the lifting plate 5 to move downward. A positioning cover 10 and a pressing plate 9 are correspondingly arranged above the test plate 27, so that the fixing plate 7 drives each corresponding pressing plate 9 at the bottom to be accurately pressed against the test plate 27, ensuring the pressing effect of each pressing plate 9 on the composite fabric above each test plate 27, which is beneficial to improving the stability of the composite fabric on the surface of the test plate 27 and facilitating the accurate detection of the humidity sensor inside the test plate 27. When the fixing plate 7 moves downward, the pressing block 12 at the bottom end of the lifting plate 5 and the heat transfer plate 11 at the bottom end of the fixing plate 7 descend synchronously, causing the pressing block 12 and the heat transfer plate 11 to squeeze the reset plate 13 from above, so that the reset plate 13 drives the tensioning sleeve 15 to disconnect the turntable 16 and the rotating rod 17, facilitating the subsequent rotation of the fan blade 23 without interfering with the turntable 16. At the same time, to ensure the detection accuracy, the detection environment is adjusted according to the detection requirements of the composite material. Under the action of the electric push rod 30 driving the connecting plate 31, when the electric push rod 30 is powered on, through the meshing connection between the toothed plate 37 and the gear column 32, the gear column 32 synchronously drives the horizontal toothed racks 34 on both sides to perform synchronous telescopic movement. With the upper pressing plate 35 fixedly connected to the bottom end of the horizontal toothed rack 34, the horizontal toothed rack 34 drives the upper pressing plate 35 at the bottom to switch between the heating plate 38, the cooling plate 39 and the interval, facilitating the temperature change switching inside the fan blade 23 and realizing the synchronous detection of the composite material in different environments. At the same time, when the lifting plate 5 descends, by rotatably connecting the transmission rod 41 inside the lifting plate 5, the lifting plate 5 drives the transmission rod 41 at the bottom to be inserted above the vertical rod 19, so that the fan blade 23 synchronously drives the transmission rod 41 to rotate through the vertical rod 19 during rotation. At the same time, the bottom end of the liquid storage cylinder 42 is connected to the fixed pipe 8 through a hose for each unequal flow control hole 44.The liquid supply amount above each test board 27 is made different, so that the liquid discharge amount on the surface of the composite material is synchronous and equidistant, which is convenient for detecting the composite material with curve liquid supply in the same environment, ensuring accurate dynamic detection of the composite material in the same environment, and greatly improving the detection efficiency and accuracy.

[0071] A test method applied to a drying test device for a composite fabric, comprising the following steps:

[0072] S1. Preparation before testing: Drive the fan blade 23 to rotate through the driving motor 24. When there is no limiting effect above the reset plate 13, the reset plate 13 moves upward under the elastic action of the reset spring 14, so that the reset plate 13 drives the tensioning sleeve 15 inside to connect the turntable 16 and the rotating rod 17, so that the rotating rod 17 can drive the turntable 16 to rotate. At the same time, when the driving motor 24 is powered on, the fan blade 23 blows air tightly on the surface of the bottom block 26 on one side of the side plate 25. Through the transmission connection between the first bevel gear 21 and the second bevel gear 22, and under the transmission connection between the first bevel gear 21 and the vertical rod 19, the rotating rod 17 synchronously drives the turntable 16 to rotate, so that the turntable 16 drives the cleaning block 28 to perform telescopic movement through the crank rod 29. When the cleaning block 28 is slidably connected to the inside of the side plate 25, the cleaning block 28 wipes on the surface of the bottom block 26, avoiding the detection accuracy of the residues on the surface of the bottom block 26 and facilitating the user to accurately lay the test materials on the surface of the bottom block 26;

[0073] S2. Fabric positioning: After the surface of the bottom block 26 is wiped clean, the fan blade 23 stops rotating, and the composite fabric is laid on the surface of the bottom block 26. At the same time, drive the lead screw 2 to move downward through the bidirectional motor 3, so that the lead screw 2 drives the lifting plate 5 to move downward. A positioning cover 10 and a pressing plate 9 are correspondingly arranged above the test board 27, so that the fixing plate 7 drives each corresponding pressing plate 9 at the bottom end to be accurately pressed against the test board 27, ensuring that each pressing plate 9 is accurately pressed above each test board 27, facilitating the humidity sensor inside the test board 27 to perform accurate detection;

[0074] S3. Ambient temperature changeover: When the fixed plate 7 moves downward, the pressure block 12 at the bottom end of the lifting plate 5 and the heat transfer plate 11 at the bottom end of the fixed plate 7 descend synchronously, so that the pressure block 12 and the heat transfer plate 11 squeeze the reset plate 13 from above, causing the reset plate 13 to drive the tensioning sleeve 15 to disengage the turntable 16 from the rotating rod 17, facilitating the subsequent rotation of the fan blade 23 without interfering with the turntable 16. At the same time, to ensure the accuracy of detection, the detection environment is adjusted according to the detection requirements of the composite material. Under the action of the electric push rod 30 driving the connecting plate 31, when the electric push rod 30 is energized, through the meshing connection of the toothed plate 37 and the gear column 32, the gear column 32 synchronously drives the horizontal rack bars 34 on both sides to expand and contract synchronously. Under the action of the upper pressure plate 35 fixedly connected to the bottom end of the horizontal rack bar 34, the horizontal rack bar 34 drives the upper pressure plate 35 at the bottom end to switch between the heating plate 38, the cooling plate 39 and the interval, facilitating the temperature changeover inside the fan blade 23 and realizing the synchronous detection of the composite material in different environments;

[0075] S4. Water outlet test: After the liquid control component undergoes ambient temperature change, as the lifting plate 5 descends, the lifting plate 5 drives the transmission rod 41 at the bottom to be inserted above the vertical rod 19, so that the fan blade 23 synchronously drives the transmission rod 41 to rotate through the vertical rod 19 during rotation. At the same time, by connecting the bottom end of the liquid storage cylinder 42 to the fixed tube 8 with hoses for each unequal-diameter flow control hole 44, the liquid supply amount above each test plate 27 is different, resulting in a synchronous and equidistant liquid outlet amount on the surface of the composite material, facilitating the curve liquid supply detection of the composite material in the same environment, ensuring the accurate dynamic detection of the composite material in the same environment, and greatly improving the detection efficiency and detection accuracy;

[0076] S5. Reset and cleaning: After the detection is completed, as the lifting plate 5 rises and resets, the reset plate 13 is no longer limited, so that the reset plate 13 moves upward to drive the crank rod 29, causing the cleaning block 28 to wipe the surface of the bottom block 26 after the detection is completed, facilitating the next detection.

[0077] In summary, by arranging the lifting plate 5 and the fixing plate 7 to lift above the bottom block 26, the reset plate 13 is not limited when the fixing plate 7 rises, achieving the transmission effect between the rotating rod 17 and the turntable 16 when the bottom block 26 is opened. This facilitates the rotating rod 17 to drive the cleaning block 28 to wipe the surface of the bottom block 26, realizing the reset before each detection, which is beneficial to improving the detection accuracy and objectivity. At the same time, by arranging the transmission rod 41 and the pressing block 12 at the bottom of the lifting plate 5, when the lifting plate 5 drives the fixing plate 7 to detect the composite fabric, the reset and liquid control of the cleaning block 28 can be achieved, ensuring the detection effect of the test material on the surface of the bottom block 26, avoiding the interference of the cleaning block 28, having good synchronism and high integration degree, and realizing the dynamic drying detection of the composite fabric by the user in different temperature environments, ensuring the objectivity and accuracy of the detection data.
