Description

Technical Field

[0001] The invention relates to the technical field of moisture absorption detection, in particular to a device for detecting moisture absorption of sofa fabrics. Background Art

[0002] Hygroscopicity is a crucial property for home textile fabrics. The hygroscopicity of sofa fabrics directly impacts user comfort. Highly hygroscopic fabrics are better at removing sweat from the body, leaving the user feeling dry and comfortable, while low-hygroscopic fabrics may leave the user feeling damp or sticky. Furthermore, fabrics with different hygroscopicities require different maintenance and cleaning methods. Highly hygroscopic fabrics require more extensive washing and drying procedures, while low-hygroscopic fabrics are easier to clean. When choosing sofa fabrics, consider the environment in which the sofa will be used and the cost of maintenance. Choosing fabrics with different hygroscopicities, depending on the environment (including moisture resistance and cleaning and maintenance), can extend the sofa's lifespan and maintain a positive user experience.

[0003] There are also some technical solutions for fabric moisture absorption detection devices in the prior art. For example, a Chinese patent with publication number CN117589627B discloses a fabric moisture absorption detection device, which includes a fuselage, a fuselage provided with a receiving slot, a support frame for supporting the fabric above the receiving slot, the support frame is in the shape of a rectangular frame, the support frame is provided with a fixing part for fixing the edge of the fabric, the fuselage is provided with a lifting frame for controlling the lifting of the support frame, the support frame is rotatably connected to the lifting frame, and the rotation axis is arranged along the width direction of the support frame, the end of the support frame in the length direction is connected to a traction rope, the traction rope extends upward at one end away from the support frame and is connected to a winding device, the winding device is provided on the fuselage for winding or unwinding the traction rope; the lifting frame controls the support frame. The support frame carries the fabric into the water, and during the process, the relative height of the two ends of the support frame is controlled by the length of the traction rope, so that the support frame and the fabric remain in an inclined state when entering the water, and the air under the fabric can be effectively discharged, avoiding the phenomenon of bulging under the fabric, thereby improving the accuracy of the test; however, this technical solution can only immerse one fabric sample in water at a time, and when performing hygroscopicity testing on each fabric, multiple samples must be used for hygroscopicity testing to improve the accuracy of the data; if multiple fabric samples are immersed in the same immersion box in sequence, it will cause impurities, dirt or dyes in the previous sample fabric to contaminate the immersion liquid in the immersion box, causing deviations in the weighing of subsequent samples, thereby affecting the results of the hygroscopicity test of subsequent samples;

[0030] As an embodiment of the present invention, the fixing unit includes an insertion rod 151; a cavity 152 is provided inside the connecting block 15; a gear ring 153 is rotatably connected in the cavity 152; the gear ring 153 is fixedly connected to the surface of the driving rod 141; a groove 154 is provided on the inner wall of the cavity 152; the insertion rod 151 is slidably connected in the groove 154; the insertion rod 151 and the bottom of the groove 154 are connected by a fixing spring 155; the bottom of the groove 154 is inlaid with an electromagnetic plate 156.

[0031] As an embodiment of the present invention, a flip rod 17 is installed on the inner wall of the immersion box 1; a square groove 171 is opened at the end of the flip rod 17 away from the immersion box 1; the end of the driving rod 141 close to the inner wall of the immersion box 1 is set as a square end; the flip rod 17 and the output shaft of the driving motor 16 are connected by a transmission belt 172.

[0032] As an embodiment of the present invention, a transmission rod 173 is provided between the flip rod 17 and the inner wall of the immersion box 1; the transmission rod 173 is rotatably connected to the immersion box 1; a mounting groove 174 is formed on a surface of the transmission rod 173 close to the flip rod 17; the flip rod 17 is slidingly and sealingly connected in the mounting groove 174; the mounting groove 174 is connected to the rectangular groove 161 via an oil pipe 175;

[0033] During operation, when conducting moisture absorption testing on existing sofa fabrics, only one fabric sample can be immersed in water at a time. When conducting moisture absorption testing on each fabric, multiple samples need to be used for moisture absorption testing to improve the accuracy of the data. If multiple fabric samples are immersed in the same immersion box 1 in sequence, impurities, dirt or dyes in the previous sample fabric will contaminate the immersion liquid in the immersion box 1, causing deviations in the weighing of subsequent samples, thereby affecting the results of the moisture absorption test of subsequent samples.

[0034] In the initial state, the support plate 2 is in a horizontal state, and the insertion rod 151 extends out of the groove 154 and enters the cavity 152, so that the insertion rod 151 is engaged with the gear ring 153, so that the driving rod 141 is fixed to the connecting block 15 through the insertion rod 151 and the gear ring 153; before using the soaking box 1; the user opens the box door 11; since the water inlet 12 is connected to the external water source through the water pipe, and the water outlet 13 is connected to the external drain pipe, solenoid valves are installed in the water inlet 12 and the water outlet 13; the solenoid valve of the water inlet 12 is controlled to be opened, so that water can enter the soaking box 1 through the water inlet 12; after the soaking box 1 is full, the user cuts three required fabric samples, weighs the mass of the fabric samples when dry, and then puts the fabric samples into the soaking box 1. The material sample is installed on the support plate 2, that is, first flip the splint 22 so that the splint 22 overcomes the torsion force of the torsion spring and rotates in the direction away from the support plate 2, and then place the sofa fabric to be tested on the upper end of the support plate 2, so that the edge of the sofa fabric close to the splint 22 can be located between the support plate 2 and the splint 22; then loosen the splint 22, so that the splint 22 rotates in the direction close to the support plate 2 under the action of the restoring force of the torsion spring, so that the splint 22 clamps the sofa fabric on the support plate 2; similarly, clamp the remaining two fabric samples on the other two support plates 2 respectively; then control the electric push rod 14 to extend so that the electric push rod 14 can push the driving rod 141 down through the connecting block 15, so that the driving rod 14 1 drives multiple support plates 2 to descend synchronously; when the driving rod 141 descends and approaches the T-shaped rod 162, the control electromagnetic sheet 164 is energized, so that the electromagnetic sheet 164 absorbs the T-shaped rod 162 and squeezes the connecting spring 163 into the rectangular groove 161; so that the T-shaped rod 162 does not block the driving rod 141 until the driving rod 141 descends to face the T-shaped rod 162, and the control electric push rod 14 stops extending. At this time, the vertical groove 142 near one end of the driving rod 141 faces the T-shaped rod 162; at this time, the control electromagnetic sheet 164 is de-energized, so that the T-shaped rod 162 extends out of the rectangular groove 161 and goes deep into the vertical groove 142 under the push of the restoring force of the connecting spring 163. At the same time, the control electromagnetic plate 156 is energized, so that The electromagnetic plate 156 can absorb the insertion rod 151 and squeeze the fixing spring 155 into the groove 154, so that the insertion rod 151 is separated from the gear ring 153, and the driving motor 16 is controlled to rotate, so that the driving motor 16 can drive the driving rod 141 to rotate through the T-shaped rod 162, so that the driving rod 141 drives the gear ring 153 fixed on the surface to rotate in the cavity 152, and at this time the driving rod 141 drives the support plate 2 connected thereto to rotate synchronously; because the two adjacent support plates 2 are threadedly connected by the connecting rod 21, the support plate 2 connected to the driving rod 141 can drive the other two support plates 2 to rotate synchronously through the connecting rod 21, so that the three support plates 2 not only have the same rotation direction, but also have the same inclination angle;When the three fabrics are immersed in the liquid at the same inclination angle, it not only helps to avoid the formation of air cavities and bulges, but also makes the contact between the fabric and the liquid more uniform, thus more accurately reflecting the moisture absorption performance of the fabric. In addition, when the three fabrics are immersed in the soaking liquid at the same inclination angle, each sample is subject to the same mechanical and physical conditions, thereby reducing the variables in the experiment, improving the consistency and comparability of the results, and making the test results more reliable and accurate.

[0035] After the support plate 2 rotates to the desired tilt angle, the control electromagnetic plate 156 is powered off, so that the insertion rod 151 extends out of the groove 154 under the push of the restoring force of the fixing spring 155 and engages with the gear ring 153, so that the gear ring 153 is blocked by the insertion rod 151 and cannot rotate in the cavity 152. At this time, the control electromagnetic plate 164 is energized, so that the electromagnetic plate 164 attracts the T-shaped rod 162 to extend out of the vertical groove 142 and squeezes the connecting spring 163 into the rectangular groove 161, so that the T-shaped rod 162 is separated from the driving rod 141. At this time, the driving motor 16 is controlled to drive the T-shaped rod 162 to rotate and reset; the electric push rod 14 is controlled to extend and push the three inclined support plates 2 to descend synchronously through the driving rod 141, so that the three inclined support plates 2 can drive the fabric samples clamped on the surface to spread into the water at the same time; the descending driving rod 141 is close to the flip rod 17, and since the mounting groove 174 in the transmission rod 173 is connected to the rectangular groove 161 through the oil pipe 175, when the electromagnetic sheet 164 is powered off, the T-shaped rod 162 extends out of the rectangular groove 161. At this time, The space in the rectangular groove 161 is increased, so that the hydraulic oil in the installation groove 174 flows into the rectangular groove 161 through the oil pipe 175, so that the flip rod 17 in the installation groove 174 is attracted by the negative pressure and enters the installation groove 174. At this time, the flip rod 17 in the installation groove 174 will not block the driving rod 141, so that the driving rod 141 can pass from the side of the flip rod 17 away from the transmission rod 173 and enter the liquid surface under the push of the electric push rod 14. When the support plate 2 drives the fabric sample to completely penetrate the liquid surface, the control The electromagnetic plate 156 is energized, so that the electromagnetic plate 156 attracts the insertion rod 151 and enters the groove 154, so that the insertion rod 151 is no longer engaged with the gear ring 153, so that the gear ring 153 is unobstructed. At this time, the support plate 2 flips to a horizontal state under the action of its own gravity. At this time, the electromagnetic plate 156 is controlled to be deenergized, so that the insertion rod 151 is pushed out of the groove 154 and engaged with the gear ring 153 under the restoring force of the fixing spring 155; the insertion rod 151 cooperates with the gear ring 153 and fixes the support plate 2 in a horizontal state;

[0036] After soaking for a certain period of time, the electric push rod 14 is controlled to pull the driving rod 141 and the support plate 2 to rise. When the driving rod 141 rises to the flip rod 17, the support plate 2 drives the fabric sample to be located at the liquid surface of the soaking liquid. At this time, the upper end surface of the rising fabric sample will hold excess water, thereby prolonging the subsequent draining process and reducing the detection efficiency of the fabric sample. To this end, the present invention provides a transmission rod 173 and a flip rod 17, so that the flip rod 17 can drive the support plate 2 to flip through the driving rod 141, so that the side of the fabric sample holding the excess water flips downward, thereby The fabric sample that holds excess water is turned over and dumped, thus preventing the fabric sample from holding excess water, speeding up the drainage time of the fabric sample, and thus improving the testing efficiency of the fabric sample. Compared with the prior art method of scraping the lower end surface of the fabric sample using a horizontal axis, the present invention directly turns the fabric sample over, thus preventing the fabric sample from being physically squeezed by the horizontal axis, ensuring that the fabric sample can drain naturally, and thus reducing the influence of external physical conditions on it, thereby reducing the variables in the experiment, improving the consistency and comparability of the results, and making the test results more reliable and accurate.

[0037] When the driving rod 141 rises to the flip rod 17, the electromagnetic plate 164 is energized, so that the electromagnetic plate 164 can absorb the T-shaped rod 162 into the rectangular groove 161; because the T-shaped rod 162 is slidingly sealed and connected to the rectangular groove 161, and the rectangular groove 161 is filled with hydraulic oil, the T-shaped rod 162 can push the hydraulic oil in the rectangular groove 161 through the oil pipe 175 into the mounting groove 174 in the transmission rod 173, so that the hydraulic oil entering the mounting groove 174 can push the flip rod 17 out of the mounting groove 174, so that the flip rod 17 contacts the driving rod 141. At this time, the square end of the driving rod 141 cooperates with the square groove 171 of the flip rod 17; so that the square end of the driving rod 141 is inserted into the square groove 171 of the flip rod 17; then the driving motor 16 is controlled to rotate, so that the driving motor 16 can pass through the transmission belt 172 The transmission rod 173 is driven to rotate, so that the transmission rod 173 drives the driving rod 141 to rotate through the flip rod 17, so that the driving rod 141 drives the fabric sample to flip 180 degrees through the support plate 2, so that when the fabric sample is flipped, the excess water on the top of the fabric sample can be quickly discharged; then the electromagnetic plate 164 is controlled to be de-energized, so that the hydraulic oil in the installation groove 174 flows back into the rectangular groove 161 through the oil pipe 175, so that the flip rod 17 moves away from the driving rod 141 and enters the installation groove 174. At this time, the electric push rod 14 continues to pull the horizontal support plate 2 upward, so that the support plate 2 can drive the fabric sample downward, so that the fabric sample is evenly drained. When the fabric sample is drained to no longer have obvious liquid dripping, the fabric sample is removed and weighed, and the moisture absorption performance of the sofa fabric is calculated based on the change in the mass of the fabric sample;

[0038] The present invention provides a driving rod 141 and a connecting rod 21, so that the connecting rod 21 can connect the three support plates 2, and the electric push rod 14 pushes the three connected support plates 2 into the water simultaneously and synchronously through the driving rod 141, so that the three fabric samples can be immersed at the same time and in the same environment, thereby eliminating the errors caused by the immersion time and environmental changes; ensuring the consistency of the test conditions, thereby improving the accuracy of the moisture absorption detection of the fabric samples; and further enhancing the practical application effect of the present invention.

[0039] As an embodiment of the present invention, a slot 176 is formed on the inner ring wall of the transmission belt 172 ; protrusions 177 are fixedly connected to the surfaces of the output shaft of the drive motor 16 and the transmission rod 173 ; and the protrusions 177 engage with the slot 176 .

[0040] As an embodiment of the present invention, a needle 23 is fixedly connected to the upper end surface of the support plate 2; the needle 23 is located between the splint 22 and the support plate 2; a slot 24 is provided on the side of the splint 22 close to the needle 23; a pressure plate 25 is slidingly and sealingly connected in the slot 24; the pressure plate 25 is fixedly connected to the bottom of the slot 24 through a support spring 26; a needle hole 27 that cooperates with the needle 23 is provided on the side of the pressure plate 25 away from the slot 24.

[0041] As an embodiment of the present invention, a push groove 28 is defined in the side wall of the clamping plate 22; a push plate 281 is slidably and sealably connected to the push groove 28; an oil passage 282 is defined inside the clamping plate 22; one end of the oil passage 282 is connected to the push groove 28, and the other end is connected to the slot 24;

[0042] During operation, in the process of the turning rod 17 driving the driving rod 141 to rotate, since the support plate 2 drives the fabric sample to be located at the liquid surface, the turning rod 17 and the driving rod 141 are partially immersed in the liquid surface. At this time, part of the transmission belt 172 also penetrates into the liquid surface, so that the transmission belt 172 is transmitted in the water; however, the transmission effect of the transmission belt 172 is affected when it is transmitted in the water; because water can reduce the friction of the transmission belt 172, thereby causing the transmission belt 172 to slip and reduce the power transmission efficiency; for this purpose, a groove 176 is provided on the inner ring wall of the transmission belt 172, and a protrusion 177 is fixed on the surface of the output shaft of the drive motor 16 and the transmission rod 173, so that The output shaft of the drive motor 16 and the transmission rod 173 engage with the groove 176 of the inner ring wall of the transmission belt 172 through the protrusions 177 on the surface, so that the output shaft of the drive motor 16 and the transmission rod 173 push the groove wall of the groove 176 through the protrusions 177 on the surface, thereby pushing the transmission rod 173 to rotate between the output shaft of the drive motor 16 and the transmission rod 173, thereby preventing the surface friction of the transmission belt 172 that is wet from being reduced and causing slipping, thereby ensuring that the transmission belt 172 can rotate stably between the output shaft of the drive motor 16 and the transmission rod 173, thereby improving the transmission effect between the output shaft of the drive motor 16 and the transmission rod 173;

[0043] When the support plate 2 uses the clamping plate 22 to clamp the fabric sample, the fabric sample located between the clamping plate 22 and the support plate 2 has poor hygroscopicity due to the squeezing of the clamping plate 22, thereby affecting the overall hygroscopicity of the fabric sample and further affecting the accuracy of the hygroscopicity detection; for this purpose, the present invention provides a needle 23. When in use, the user presses the pushing plate 281 into the pushing groove 28, so that the hydraulic oil in the pushing groove 28 is squeezed by the pushing plate 281 and enters the slot 24 through the oil channel 282; so that the pressure plate 25 in the slot 24 is pushed by the hydraulic oil to squeeze the supporting spring 26 into the slot 24. At this time, the pressure plate 25 is away from the needle 23, so that the needle 23 extends out of the needle hole 27. At this time, the user flips the clamping plate 22 so that the clamping plate 22 drives the pressing plate 25 to rotate synchronously; then the user places the edge of the fabric sample above the needle 23, so that the needle 23 pierces the fabric sample. Then the splint 22 is flipped over and reset; at this time, the pushing plate 281 is released, so that the pushing plate 281 no longer generates a driving force on the hydraulic oil in the pushing groove 28. At this time, the pressure plate 25 extends out of the slot 24 under the push of the restoring force of the support spring 26, so that the pressure plate 25 drives the needle hole 27 on the side away from the slot 24 close to the needle 23, so that the needle 23 is inserted into the needle hole 27, and the hydraulic oil entering the slot 24 will also flow back to the pushing groove 28 through the oil channel 282, so that the pushing plate 281 in the pushing groove 28 is reset; through the setting of the needle 23, when the needle 23 penetrates the fiber gap of the fabric sample and fixes the fabric sample, the needle 23 will not squeeze the fabric sample, so that the edge of the fabric sample between the splint 22 and the support plate 2 can also fully and effectively absorb water, thereby improving the overall moisture absorption effect of the fabric sample, making the moisture absorption test of the fabric sample more accurate.
