This device simulates the human sweating process and measures the fabric's effect on heat transfer to evaluate its cooling performance.

[0003] For related technologies, please refer to the patent application with announcement number CN222144918U, which discloses a fully automatic fabric coolness tester, including a test platform, a lifting mechanism is provided on the upper part of the test platform, and a support plate is provided on the side of the lifting mechanism, a measuring mechanism is provided on the lower part of the support plate, and the measuring mechanism and the support plate are fixedly connected, and a constant temperature plate is provided on the surface of the test platform, and the constant temperature plate is located below the measuring mechanism. The application provides a movable plate on the surface of the screw and a mounting seat on the surface of the movable plate, and a heating mechanism is provided inside the mounting seat. The heating temperature of the heating mechanism is controlled by a controller, and at the same time, a transverse mechanism drives the movable plate to move to the lower part of the measuring mechanism to heat the measuring mechanism, and brings the measuring mechanism, which has a temperature higher than that of the sample, into contact with the sample, measures the change in the temperature of the measuring mechanism over time, and calculates its contact coolness coefficient to evaluate the comfort of the fabric, so that users can more intuitively choose suitable fabric products.

[0004] Regarding the above-mentioned related technologies, during the process of fabric testing, the fabric and the measuring mechanism need to be heated separately. During this process, the fabric needs to be removed from the constant temperature plate. The steps are cumbersome and there is a risk of burns. Therefore, a thermal flow fabric moisture absorption and cooling sensitivity detection device and detection method are urgently needed to solve the above technical problems. Summary of the Invention

[0005] In order to improve detection efficiency, the present invention provides a thermal flow type fabric moisture absorption and cooling sensation detection device and detection method.

[0006] In a first aspect, the present invention provides a thermal flow type fabric moisture absorption and cooling sensation detection device, which adopts the following technical solution:

[0007] The top of the fixing plate is provided with a fixing column, and the fixing column is provided with a fixing column, and the fixing column is provided with a fixing column. The ... The lower end surface is fixedly connected to a first heating block, and the side of the fabric probe close to the first heating block is a sensing surface for simulating human skin. A rotating wheel is coaxially fixedly connected to the connecting rod, and a reversing plate is provided on the side of the fixed column. The reversing plate is extended along the height direction of the fixed column. A first rack is vertically provided on the reversing plate, and the rotating wheel is meshed with the first rack. A second heating block is provided on the workbench, and a carrier for placing fabric samples is provided on the upper end surface of the second heating block. The carrier is arranged corresponding to the fabric probe, and a rotating motor is provided on the upper end surface of the support plate. The output shaft of the rotating motor is coaxially fixedly connected to the rotating shaft. When the fabric probe is located at the top end of the fixed column, the sensing surface abuts against the first heating block; when the fabric probe is located at the bottom end of the fixed column, the sensing surface abuts against the second heating block.

[0008] By adopting the above technical solution, when it is necessary to perform a cooling sensation test on a fabric sample, the staff will place the fabric sample on the carrier, and then start the first heating block and the second heating block respectively. The first heating block increases the temperature of the sensing surface of the fabric probe, thereby simulating human skin, and the second heating block heats the fabric sample so that the temperature of the fabric sample is slightly lower than the temperature of the sensing surface of the fabric probe. Then, the rotating motor is started, and the rotating motor drives the rotating shaft to rotate, thereby driving the lifting block to move up and down, and the lifting block drives the fabric probe to move up and down. When the fabric probe drops a certain distance, the first rack engages with the rotating wheel, thereby driving the rotating wheel to rotate, and then driving the fabric probe to rotate, and the fabric probe continues to drop. When the rotating wheel is disengaged from the first rack, the sensing surface of the fabric probe rotates downward and corresponds to the carrier, and then continues to drop to make it contact with the fabric sample. Then, the cooling sensation of the fabric sample is evaluated based on the data fed back by the sensing surface of the fabric probe, which reduces the detection steps and avoids the need to remove the fabric sample when using a single heating block, which is conducive to improving work efficiency and safety.

[0009] Optionally, one side of the fixed plate is provided with a first temperature sensor, a second temperature sensor and a coolness detection sensor for monitoring the temperature change of the fabric probe over time from top to bottom, the first sensor is electrically connected to the first heating block, the second sensor is electrically connected to the second heating block, and the coolness detection sensor is electrically connected to the sensing surface of the fabric probe. The other side of the fixed plate is provided with a PLC controller for monitoring and controlling the operation of each drive on the equipment.

[0010] By adopting the above technical solution, when it is necessary to detect the coolness of a fabric sample, the staff controls the operation of various drives on the equipment through the PLC controller, and further determines the temperature change range through the first temperature sensor, the second temperature sensor and the coolness detection sensor, which is conducive to further improving the accuracy of the detection results.

[0011] Optionally, the bottom end of the rotating shaft is coaxially fixedly connected with a synchronous wheel, one side of the synchronous wheel is meshed with a connecting wheel, and the other side of the connecting wheel is meshed with a one-way ratchet, the bottom end of the one-way ratchet is provided with a rotating disk, and the bottom end of the rotating disk is provided with a support seat, the support seat is fixedly connected to the upper end surface of the workbench, and the support seat is rotatably connected to the rotating disk. There are two carrier seats, and the two carrier seats are arranged relative to each other about the center of the rotating disk. The carrier seats are both located on the outside of the rotating disk. When the one-way ratchet rotates clockwise, that is, when the fabric probe rises, the rotating disk rotates synchronously; when the one-way ratchet rotates counterclockwise, that is, when the fabric probe descends, the rotating disk is stationary.

[0012] By adopting the above technical solution, when another fabric sample needs to be tested, the staff first starts the rotating motor, and the rotating motor drives the fabric probe to reset. During the resetting process, the synchronous wheel rotates to drive the connecting wheel to rotate, thereby driving the one-way ratchet to rotate, and then under the action of the one-way ratchet, the rotating disk is driven to rotate synchronously, thereby realizing the position switching of the two loading seats. On the one hand, it is convenient to recover the previous fabric sample, and on the other hand, it is convenient to conduct the coolness test of another fabric sample. During the test, the staff starts the rotating motor again, and the rotating motor drives the fabric probe to descend. During the descent, under the action of the one-way ratchet, the rotating disk is stationary, and the loading seat is always located below the fabric probe, which is convenient for subsequent testing.

[0013] Optionally, the object carrier is fixedly connected to a curved plate on one side away from the fixed column, the curved plates are located on the outside of the rotating disk, and a second rack is provided on the outside of the curved plates. The upper end surface of the workbench is rotatably connected to two support shafts, and the two support shafts are respectively arranged on the inner and outer sides of the workbench, and the two support shafts are arranged relative to each other about the center of the rotating disk. A driven wheel is coaxially fixedly connected to the support shaft, and a rotating rod is fixedly connected to the top end of the driven wheel, and a plurality of adsorption brushes for cleaning impurities on the surface of the fabric sample are provided on the lower end surface of the rotating rod.

[0014] By adopting the above technical solution, during the switching of the carrier, the rotating disk rotates, and the rotation of the rotating disk drives the arc plate to rotate, so that the second rack on the arc plate engages with the driven wheel, and then drives the driven wheel to rotate. The rotation of the driven wheel drives the rotating rod to rotate, so that the adsorption brush rotates to clean the fabric sample on the carrier, so that the fabric sample can be ensured to be neat before testing, and after testing, it is cleaned again to ensure the smooth progress of subsequent experiments.

[0015] Optionally, a plurality of spray heads for controlling the humidity of the fabric sample are provided in the object carrier, and the spray heads are evenly arranged.

[0016] By adopting the above technical solution, when the humidity of the fabric sample needs to be changed, the staff starts the sprinkler head, and the sprinkler head sprays water to achieve the change of the humidity of the fabric sample to simulate human sweating, which is easy to operate and helps to improve work efficiency.

[0017] In a second aspect, the present application provides a detection method comprising the following steps:

[0018] S1: The staff placed the fabric sample on the carrier under the fabric probe, and then changed the humidity of the fabric sample through the spray head to simulate human sweating;

[0019] S2: Start the first heating block and the second heating block to heat the fabric probe and the fabric sample respectively, and make the temperature of the fabric probe slightly higher than the temperature of the fabric sample;

[0020] S3: Start the rotating motor, which drives the fabric probe to descend. During the descent, the fabric probe is flipped so that the sensing surface of the fabric probe faces the fabric sample and the two are quickly brought into contact.

[0021] S4: Observe and record the temperature change of the cooling property detection sensor, and evaluate the cooling property of the fabric sample based on the record.

[0022] In summary, the present invention includes at least one of the following beneficial technical effects:

The first heating block increases the temperature of the sensing surface of the fabric probe to simulate human skin, and the second heating block heats the fabric sample so that the temperature of the fabric sample is slightly lower than the temperature of the sensing surface of the fabric probe, and then start the rotating motor, which drives the rotating shaft to rotate. The lifting block is thereby driven to move up and down, and the lifting block drives the fabric probe to move up and down. When the fabric probe is lowered a certain distance, the first rack engages with the rotating wheel, thereby driving the rotating wheel to rotate, thereby driving the fabric probe to rotate, and the fabric probe continues to descend. When the rotating wheel is disengaged from the first rack, the sensing surface of the fabric probe rotates downward and corresponds to the object carrier, and then continues to descend to make it contact with the fabric sample. Then, the cooling sensation of the fabric sample is evaluated based on the data fed back by the sensing surface of the fabric probe, which reduces the detection steps and avoids the need to remove the fabric sample when using a single heating block, which is conducive to improving work efficiency and safety.

By setting up a sprinkler head, when the humidity of the fabric sample needs to be changed, the staff starts the sprinkler head, and the sprinkler head sprays water to achieve the change of the humidity of the fabric sample to simulate human sweating, which is easy to operate and helps to improve work efficiency.
