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 very important property for home textile fabrics. The hygroscopicity of sofa fabrics directly affects the comfort of users. Fabrics with high hygroscopicity can better remove sweat from the body surface, making users feel dry and comfortable, while fabrics with low hygroscopicity may make people feel damp or sticky. Moreover, fabrics with different hygroscopicity have different maintenance and cleaning methods. Fabrics with high hygroscopicity require more washing and drying measures, while fabrics with low hygroscopicity are easier to clean. When choosing sofa fabrics, the use environment and maintenance cost of the sofa should be taken into consideration, that is, sofas with different hygroscopicity fabrics should be selected according to different environments (considering moisture resistance, cleaning and maintenance of the sofa) to extend the service life of the sofa and maintain a good user experience. Some technical solutions for fabric hygroscopicity detection devices have also appeared in the prior art. For example, a Chinese patent with publication number CN117589627B discloses a fabric hygroscopicity detection device, including a fuselage, a fuselage is provided with a receiving slot, a support frame for supporting the fabric is provided 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 end of the traction rope away from the support frame extends upward and is connected to a winding device, the winding device is arranged on the fuselage, and is used to reel in or unreel the traction rope; the lifting frame controls the support. 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 detection; 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 are required to perform hygroscopicity testing to improve the accuracy of the data; if multiple fabric samples are immersed in the same immersion box in turn; it will cause impurities, dirt or dyes in the fabric of the previous sample 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; In view of this, in order to overcome the above technical problems, the present invention proposes a sofa fabric moisture absorption detection device to solve the above technical problems.

[0020] 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.

[0021] 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 provided on a side of the transmission rod 173 close to the flip rod 17; the flip rod 17 is slidably sealed and connected in the mounting groove 174; the mounting groove 174 is connected to the rectangular groove 161 through an oil pipe 175; During operation, when the existing sofa fabric is subjected to moisture absorption test, only one fabric sample can be immersed in water each time, and when the moisture absorption test is performed on each fabric, multiple samples need to be used for moisture absorption test 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; 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 meshed 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 a water pipe, and the water outlet 13 is connected to the external drainage 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 filled, 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, the clamping plate 22 is turned over first, so that the clamping plate 22 overcomes the torsion force of the torsion spring and rotates in the direction away from the support plate 2, and then the sofa fabric to be tested is placed on the upper end of the support plate 2, so that the edge of the sofa fabric close to the clamping plate 22 can be located between the support plate 2 and the clamping plate 22; then the clamping plate 22 is loosened, so that the clamping plate 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 clamping plate 22 clamps the sofa fabric on the support plate 2; similarly, the remaining two fabric samples are clamped on the other two support plates 2 respectively; then the electric push rod 14 is controlled 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 to enter the rectangular groove 161; so that the T-shaped rod 162 will not block the driving rod 141, until the driving rod 141 descends to face the T-shaped rod 162, 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, and 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 supporting plate 2 connected thereto to rotate synchronously; because the two adjacent supporting plates 2 are threadedly connected through the connecting rod 21, the supporting plate 2 connected to the driving rod 141 can drive the other two supporting plates 2 to rotate synchronously through the connecting rod 21, so that the three supporting 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 is not only helpful to avoid the formation of air cavity bulges, but also to make the contact between the fabric and the liquid more uniform, so as to more accurately reflect the moisture absorption performance of the fabric; and when the three fabrics are immersed in the soaking liquid at the same inclination angle, each sample is affected by 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; 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 meshes 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 absorbs 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 diffuse into the water at the same time; the descending driving rod 141 is made close to the flip rod 17, because the installation 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 adsorbed by the negative pressure and enters the installation groove 174. At this time, the flip rod 17 located 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 into the liquid surface, the control The electromagnetic plate 156 is powered on, so that the electromagnetic plate 156 absorbs 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 not blocked, and the support plate 2 is flipped to a horizontal state under the action of its own gravity. At this time, the electromagnetic plate 156 is controlled to be powered off, so that the insertion rod 151 is pushed out of the groove 154 and engaged with the gear ring 153 under the push of the restoring force of the fixing spring 155; so that the insertion rod 151 cooperates with the gear ring 153 and fixes the support plate 2 to a horizontal state; 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 drainage process and reducing the detection efficiency of the fabric sample. To this end, the present invention sets 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 can hold excess water and be turned over and dumped, so that the fabric sample can avoid holding excess water, speed up the drainage time of the fabric sample, and thus improve the detection efficiency of the fabric sample; compared with the prior art that uses a horizontal axis to scrape the lower end surface of the fabric sample, the present invention directly turns the fabric sample over to avoid the physical squeezing of the fabric sample by the horizontal axis, ensuring that the fabric sample can drain naturally, thereby reducing the impact of external physical conditions on it, thereby reducing the variables in the experiment, improving the consistency and comparability of the results, and making the detection results more reliable and accurate; When the driving rod 141 rises to the flip rod 17, the electromagnetic sheet 164 is energized so that the electromagnetic sheet 164 can absorb the T-shaped rod 162 and enter the rectangular groove 161; because the T-shaped rod 162 is slidingly sealed and connected in 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 installation groove 174 in the transmission rod 173, so that the hydraulic oil entering the installation groove 174 can push the flip rod 17 to extend out of the installation groove 174, so that the flip rod 17 contacts the driving rod 141, and 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; and 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 flipping 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 trapped on the top of the fabric sample can be quickly discharged; then the electromagnetic sheet 164 is controlled to be powered off, so that the hydraulic oil in the installation groove 174 flows back to the rectangular groove 161 through the oil pipe 175, so that the flipping rod 17 is away from the driving rod 141 and enters the installation groove 174, and 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, and when the fabric sample is drained to no longer have obvious liquid dripping, the fabric sample is taken down and weighed, and the moisture absorption performance of the sofa fabric is calculated according to the mass change of the fabric sample; The present invention sets 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 in the same time and 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 improving the practical application effect of the present invention.

[0022] As an embodiment of the present invention, a slot 176 is formed on the inner ring wall of the transmission belt 172 ; a protrusion 177 is fixedly connected to the surface of the output shaft of the driving motor 16 and the transmission rod 173 ; and the protrusion 177 is meshed with the slot 176 .

[0023] 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 a 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 matching the needle 23 is provided on a side of the pressure plate 25 away from the slot 24.

[0024] As an embodiment of the present invention, a push groove 28 is formed on the side wall of the clamping plate 22; a push plate 281 is slidably and sealably connected in the push groove 28; an oil passage 282 is formed 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; During operation, when the flip rod 17 drives the driving rod 141 to rotate, because the support plate 2 drives the fabric sample to be located at the liquid surface, the flip rod 17 and part of the driving rod 141 are in a state of being 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 in the water will be affected; because water will 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 fixedly connected on the surface of the output shaft of the driving motor 16 and the transmission rod 173, so that The output shaft of the drive motor 16 and the transmission rod 173 are engaged 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, avoiding the problem of slipping due to the reduced friction on the surface of the transmission belt 172 stained with water, thereby ensuring that the transmission belt 172 can stably rotate between the output shaft of the drive motor 16 and the transmission rod 173, and improving the transmission effect between the output shaft of the drive motor 16 and the transmission rod 173; 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 hygroscopicity detection; in this regard, the present invention sets a needle 23. When in use, the user presses the pushing plate 281 to enter 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; the pressing plate 25 in the slot 24 is pushed by the hydraulic oil to squeeze the supporting spring 26 to enter the slot 24. At this time, the pressing 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 clamping plate 22 is flipped 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, and the pressing plate 25 extends out of the slot 24 under the push of the restoring force of the supporting spring 26, so that the pressing plate 25 drives the needle hole 27 away from the side of the slot 24 to approach 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 to fix the fabric sample, the needle 23 will not squeeze the fabric sample, so that the edge of the fabric sample between the clamping plate 22 and the supporting plate 2 can also fully and effectively absorb water, thereby improving the overall moisture absorption effect of the fabric sample, making the moisture absorption detection of the fabric sample more accurate.
