DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] Embodiment 1

[0040] In order to solve the problem that the existing testing equipment is not convenient for taking and placing fabrics, and the heat in the equipment is easily lost when taking and placing fabrics, resulting in a long heating time during fabric testing, thus affecting the testing efficiency, please refer to Figures 1 - 3 , Figure 5, a fabric heat insulation and heat preservation performance detection device provided by the present invention includes a constant temperature box 1 and a rotating plate 2 rotatably arranged on the top of the constant temperature box 1. Four first through holes 101 are evenly distributed along the circumference on the top surface of the constant temperature box 1. A second through hole 201 matching the first through hole 101 is provided on the rotating plate 2. A pressing frame 202 for fixing the fabric is hinged at the second through hole 201; it also includes a detection box 3 located above the rotating plate 2. Four grooves 301 are evenly distributed along the circumference on the surface of the detection box 3. A working area for placing and taking the fabric is formed between the grooves 301 and the rotating plate 2. Four detection cavities 302 are provided at the bottom of the detection box 3. A detection component 4 capable of lifting and adjusting is arranged in each detection cavity 302. The operation of placing and taking the fabric can be carried out by rotating the pressing frame 202 to the working area at the groove 301 through the rotating plate 2. Therefore, the convenience of placing and taking the fabric can be greatly improved. Multiple fabrics can be detected simultaneously through multiple detection cavities 302, and the detection efficiency can be greatly improved. Moreover, multiple fabrics are heated simultaneously by the constant temperature box 1, which can ensure that the heat uniformity of each fabric is consistent, and the detection accuracy is better. The constant temperature box 1 can quickly reach the set temperature, and the detection process is more efficient.

[0041] As Figure 2 , Figure 4 shown, an installation rod 102 is fixedly arranged at the center of the top of the constant temperature box 1. The rotating plate 2 is rotatably sleeved on the installation rod 102. Anti-slip patterns are provided on the outer surface of the rotating plate 2. The detection box 3 is fixedly sleeved on the installation rod 102. In order to improve the sealing performance of the whole device and avoid heat loss, sealing rings are provided between the rotating plate 2 and the constant temperature box 1 and between the rotating plate 2 and the detection box 3. On the one hand, the rotating plate 2 serves to place the fabric, and on the other hand, it serves to close the first through hole 101. When the pressing frame 202 is rotated to the working area of the groove 301 to place and take the fabric, at this time, the solid part of the rotating plate 2 closes the first through hole 101, avoiding heat loss in the constant temperature box 1 and enabling the temperature in the constant temperature box 1 to be maintained at a suitable temperature all the time.

[0042] In order to facilitate the control of the rotation angle of the rotating plate 2 so that the fabric can be quickly rotated to the detection and placement / taking positions, as Figure 4As shown in the figure, a rotating cylinder 203 matching the mounting rod 102 is fixedly provided at the center of the bottom of the rotating plate 2. There are eight card slots 204 evenly distributed along the circumference on the surface of the rotating cylinder 203. A clamping member 5 for restricting the rotation of the rotating plate 2 is provided in the top groove of the constant temperature box 1; the clamping member 5 includes a first fixed seat 501 and a first movable rod 502 movably penetrating through the first fixed seat 501. A clamping block 503 matching the card slot 204 is fixedly provided at the end of the first movable rod 502. A first spring 504 is sleeved on the first movable rod 502 between the clamping block 503 and the first fixed seat 501. When the rotating plate 2 rotates, when the card slot 204 of the rotating cylinder 203 rotates to the position of the clamping block 503, under the action of the first spring 504, the first movable rod 502 drives the clamping block 503 to extend into the card slot 204, thereby preventing the continuous rotation of the rotating plate 2. When it is necessary to continue rotating the rotating plate 2, a greater force is applied to the rotating plate 2. At this time, the rotating cylinder 203 squeezes the clamping block 503, the clamping block 503 drives the first movable rod 502 to move, and the first spring 504 is compressed until the clamping block 503 completely leaves the card slot 204. In order to facilitate the clamping block 503 to leave the card slot 204, the shape of the card slot 204 is set as an isosceles trapezoid shape.

[0043] Embodiment 2

[0044] On the basis of Embodiment 1, in order to further improve the efficiency of taking and placing the fabric, as Figures 5 - 7 shown, a notch 303 for the fabric to pass through is provided on the side of the detection cavity 302, and a cover plate unit 304 that can automatically open and close along with the rotation of the rotating plate 2 is provided at the notch 303. During the rotation of the rotating plate 2, the cover plate unit 304 can automatically open and close accordingly, thus eliminating the operation of opening and closing the cover plate unit 304, and therefore can further improve the efficiency of taking and placing the fabric and reduce the operation complexity of the operator.

[0045] The cover plate unit 304 includes a second fixed seat 304a and a second movable rod 304b movably penetrating through the second fixed seat 304a. A second wedge block 304c is fixedly provided at the top end of the second movable rod 304b, and a cover plate body 304d is fixedly provided at the bottom end of the second movable rod 304b. A second spring 304e is sleeved on the second movable rod 304b between the cover plate body 304d and the second fixed seat 304a; a toggling member 205 for driving the opening and closing of the cover plate unit 304 is provided on the rotating plate 2. The toggling member 205 includes a fixed rod 205a fixed to the top of the rotating plate 2 and a first wedge block 205b fixed to the top end of the fixed rod 205a and matching with the second wedge block 304c. When the rotating plate 2 rotates, it drives the toggling member 205 to rotate. When the first wedge block 205b of the toggling member 205 contacts the second wedge block 304c, the second wedge block 304c is squeezed downward, and the second wedge block 304c drives the second movable rod 304b and the cover plate body 304d to move downward. At this time, the second spring 304e is stretched. When the fabric just rotates to the detection position, the cover plate body 304d is completely closed. When it is necessary to take out the detected fabric, after losing the extrusion effect of the first wedge block 205b, the second spring 304e is restored under the restoring force, and the cover plate body 304d is opened to facilitate the fabric to pass through the notch portion 303.

[0046] Embodiment III

[0047] On the basis of Embodiment I and Embodiment II, in order to solve the problem that existing detection equipment generally uses advanced sensors, control systems, etc., and the manufacturing cost of the equipment is relatively high, as Figure 6 , Figure 9 shown, the detection assembly 4 includes a plurality of detection units 402 evenly distributed in each area of the fabric and in contact with the fabric. A color-changing light-emitting plate 305 matching with the detection units 402 is provided on the top of the detection box 3. The color-changing light-emitting plate 305 is divided into a plurality of display areas and corresponds to the plurality of detection units 402 one by one. The detection unit 402 adjusts the magnitude of the current in the circuit of the color-changing light-emitting plate 305 according to the thermal deformation. The color-changing light-emitting plate 305 displays different colors according to the magnitude of the current to visually display the heat insulation and heat preservation performance of each area of the fabric. The color of the color-changing light-emitting plate 305 can be set based on requirements. For example, three colors of red, yellow, and green can be set. Red represents that the surface temperature of the fabric is high, indicating that the heat insulation and heat preservation performance of the fabric is poor. Green represents that the surface temperature of the fabric is low, indicating that the heat insulation and heat preservation performance of the fabric is good. The heat insulation and heat preservation performance of each area of the fabric can be visually judged through the color, and the surface temperature of the fabric can directly control the magnitude of the current of the color-changing light-emitting plate 305 through the detection unit 402, saving the high control cost of electrical appliances such as controllers and sensors, and without the need for complex instrument equipment, the heat insulation and heat preservation performance of the fabric can be quickly judged.

[0048] As Figure 9As shown, the detection component 4 further includes a grid plate 401 for installing and fixing a plurality of detection units 402, and a lifting screw rod 403 movably penetrating through the top surface of the detection box 3; the bottom end of the lifting screw rod 403 is rotatably connected to the top of one end of the grid plate 401, the top end of the lifting screw rod 403 is fixedly provided with an adjustment knob 404, and the grid plate 401 is slidably connected to the inner wall of the detection cavity 302. By rotating the adjustment knob 404, the adjustment knob 404 drives the lifting screw rod 403 to rotate, and the lifting screw rod 403 drives the grid plate 401 to slide along the inner wall of the detection cavity 302, so as to realize the adjustment of the height of the detection unit 402, enabling it to be closely attached to the fabric, being able to more fully sense the temperature change on the surface of the fabric, and enabling the detection component 4 to adapt to the use of fabrics with different thicknesses.

[0049] As Figure 10 shown, the detection unit 402 includes a lower cylinder body 402a and an upper cylinder body 402b; a connecting bar 402c is fixedly provided between the lower cylinder body 402a and the upper cylinder body 402b, a mounting seat 402d is movably sleeved at the upper end of the lower cylinder body 402a, the mounting seat 402d is fixed to the bottom of the grid plate 401, a fixing ring 402e is fixedly sleeved at the lower end of the lower cylinder body 402a, and a third spring 402f is fixedly provided between the fixing ring 402e and the mounting seat 402d, and the third spring 402f is sleeved on the lower cylinder body 402a. When the mounting seat 402d descends along with the grid plate 401 and the thermosensitive cylinder 402g touches the fabric, at this time the third spring 402f is compressed, and the lower cylinder body 402a rises along the mounting seat 402d, so that each detection unit 402 can be in good contact with the fabric, improving the accuracy of detection.

[0050] A thermosensitive cylinder 402g is arranged inside the lower cylinder body 402a, the bottom surface of the thermosensitive cylinder 402g abuts against the fabric during detection, an adjustment rod 402i is provided at the top of the thermosensitive cylinder 402g, and a metal block 402j is provided at the top end of the adjustment rod 402i; a coil 402k is fixedly sleeved on the upper cylinder body 402b, and the metal block 402j is slidably arranged in a chute on the surface of the upper cylinder body 402b and contacts the inner surface of the coil 402k to adjust the effective length of the coil 402k.

[0051] The thermosensitive cylinder 402g is a cylinder structure made of reversible thermosensitive material and can be reused multiple times within a certain temperature range. The preparation material can be polyurethane shape memory polymer, polylactic acid shape memory polymer or other materials that can achieve the functions of the present invention. When the temperature rises, due to the characteristics of the thermosensitive material, the length of the cylinder changes, driving the adjusting rod 402i to rise. The adjusting rod 402i drives the metal block 402j to move. The metal block 402j contacts the coil 402k. Since the temperature on the surface of the fabric is different, the deformation amount of the thermosensitive cylinder 402g is also different, so that the position of the metal block 402j in the coil 402k is also different, thus being able to change the effective length of the coil 402k based on the temperature on the surface of the fabric. When the effective length of the coil 402k changes, the current magnitude of the color-changing light-emitting plate 305 also changes accordingly, emitting different colors of bright light, so as to facilitate the operator to visually observe the heat insulation and heat preservation performance of the fabric.

[0052] To facilitate the installation and replacement of the thermosensitive cylinder 402g, the adjusting rod 402i is snap-connected to the top of the thermosensitive cylinder 402g; a pressing plate 402h for pressing the thermosensitive cylinder 402g is provided on the bottom surface of the lower cylinder body 402a. When the thermosensitive cylinder 402g needs to be replaced, the pressing plate 402h is opened, and the thermosensitive cylinder 402g is pulled out. At this time, the thermosensitive cylinder 402g is separated from the adjusting rod 402i. Under the action of gravity, the lower end of the adjusting rod 402i falls to the bottom end of the lower cylinder body 402a. Hold the adjusting rod 402i, after snapping the new thermosensitive cylinder 402g with the adjusting rod 402i, push it upward into the lower cylinder body 402a, and finally press the thermosensitive cylinder 402g tightly through the pressing plate 402h.

[0053] To enable the thermosensitive cylinder 402g to quickly recover and improve the detection efficiency, as Figure 6 、 Figure 8 shown, a heat dissipation fan 306 is also fixedly provided on the top of the detection box 3. A plurality of air outlet holes 307 communicated with the heat dissipation fan 306 are provided on the inner wall of the detection cavity 302 close to the central axis of the detection box 3. The cold air ejected from the air outlet holes 307 is used to quickly cool down the thermosensitive cylinder 402g. The heat dissipation fan 306 extracts the air in the environment or the air generated by the refrigeration equipment. After being transported through the flow channel inside the detection box 3, the air is ejected from a plurality of air outlet holes 307 to blow on the thermosensitive cylinder 402g. Under the action of the cold air, the thermosensitive cylinder 402g gradually recovers to its original state, so as to quickly perform the detection of the next batch of fabrics.

[0054] The present invention also provides a method for detecting the heat insulation and heat preservation performance of a fabric, including the following steps:

[0055] S1. Rotate the second through hole 201 to the working area at the groove 301 through the rotating plate 2, lift the pressing frame 202, place the fabric to be detected and press it tightly;

[0056] S2. Then, the fabric to be detected is transferred into the detection chamber 302 through the transfer plate 2. At this time, the second through-hole 201 coincides with the first through-hole 101, and the heat in the constant temperature box 1 contacts the fabric, and the detection assembly 4 is adjusted to a state of being closely attached to the fabric;

[0057] S3. The surface temperature of each area of the fabric is detected by multiple detection units 402. Based on the thermosensitive deformation of the detection unit 402, the current magnitude of the corresponding display area of the color-changing light-emitting panel 305 is adjusted, and the color-changing light-emitting panel 305 displays different colors to visually display the heat insulation and heat preservation performance of each area of the fabric;

[0058] S4. After the detection is completed, the second through-hole 201 is transferred to the working area at the groove 301 through the transfer plate 2. At this time, the transfer plate 2 closes the first through-hole 101, and the detected fabric is taken out, and the detection of the next batch of fabrics is continued.

[0059] The above embodiments only represent one implementation manner of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
