Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric air permeability detection, and particularly relates to a textile material air permeability detection device. BACKGROUND

[0002] As a traditional industry with a long history, the textile industry has been constantly progressing with the development of science and technology, and people's requirements for textile products are also getting higher and higher. In the past, people's demand for textile products mainly focused on basic functions such as warmth and durability. However, with the improvement of living standards, the demand for comfort is increasingly prominent. Textile products with good air permeability can keep the skin dry, reduce the feeling of stuffiness and dampness, reduce the probability of skin diseases, and improve the comfort of wearing. The existing air permeability detection device, such as the textile air permeability detection device disclosed in CN116559054A, moves through four contact pieces when in use, respectively straightens the textile horizontally and vertically, so that the textile forms a completely flat state before being pressed, but different textile materials have different properties. When the textile is relatively soft, the four contact pieces will excessively stretch the textile, so that the diagonal line of the contact piece will wrinkle after the textile is stretched, and the pores at the four corners of the textile are too large, affecting the accuracy of the air permeability detection. And with the increase of the pores of the textile, the dust and stains on the surface of the textile will penetrate into the inside of the pores during the detection process, further affecting the accuracy of the air permeability detection. SUMMARY

[0003] The purpose of the present application is to solve the problems in the background art and provide a textile material air permeability detection device.

[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: A textile material air permeability detection device, comprising a workbench, a lower pressing assembly movably mounted on the top of the workbench, the lower pressing assembly comprising a gas cover and a pressing rod, an electric push rod fixedly mounted on the top of the workbench, the output end of the electric push rod being fixedly connected with the top of the gas cover, the pressing rod being movably inserted into the inside of the gas cover, a plurality of evenly distributed thimbles being integrally formed on the bottom of the pressing rod, the thimbles being located at the eccentric position of the bottom of the pressing rod; A drive assembly movably mounted in the inside of the workbench, the drive assembly comprising a mounting seat and a supporting rod, the mounting seat being fixedly mounted in the inside of the workbench, the supporting rod being movably inserted into the inside of the mounting seat, a plurality of evenly distributed needle grooves being formed on the top of the supporting rod, the needle grooves corresponding to the thimbles; A rotating pad rotatably mounted on the bottom of the gas cover and the top of the mounting seat, a support frame integrally formed in the inside of the rotating pad, the pressing rod and the supporting rod being respectively slidably inserted into the inside of the two support frames.

[0005] The spring two is arranged between the supporting frame and the supporting rod, and the spring two has a smaller elastic force than the spring one.

[0006] The spring three is arranged between the supporting frame and the supporting rod, and the spring three has a smaller elastic force than the spring two.

[0007] The slide cylinder is integrally formed in the air cover, the supporting rod is movably inserted into the slide cylinder, the slide cylinder is integrally formed with the convex strip one and the convex strip two, the spring top block is movably connected with the side wall of the convex strip one and the convex strip two.

[0008] The convex strip one and the convex strip two are helical, the rotation direction of the convex strip one is the same as the rotation direction of the supporting rod, the rotation direction of the convex strip two is opposite to the rotation direction of the supporting rod, and the distance between the highest positions of the convex strip one and the convex strip two is greater than the diameter of the spring top block.

[0009] The side wall of the spring top block is provided with an inclined surface, and the inclined surface is attached to the side wall of the convex strip two.

[0010] The workbench is internally fixedly provided with the motor one, the output end of the motor one is fixedly connected with the gear two, the bottom of the supporting rod is fixedly connected with the gear one, and the gear two and the gear one are engaged.

[0011] The workbench is internally fixedly provided with the air pump, the output end of the air pump is fixedly connected with the air pipe, the air pipe is fixedly connected with the side wall of the air cover, the top of the workbench is fixedly provided with the placing plate, and the rotating pad is rotatably arranged on the inner side of the placing plate.

[0012] Compared with the prior art, the present application has the following advantages: 1、The present application is characterized in that the spring top block is movably connected with the side wall of the convex strip one and the convex strip two, the side wall of the spring top block is provided with an inclined surface, and the inclined surface is attached to the side wall of the convex strip two.

[0013] 2. This invention utilizes the cooperation between the pressure rod and the support rod. After the ejector pin enters the needle groove, the support rod drives the pressure rod to rotate, causing the fabric between the support rod and the pressure rod, as well as the two rotating pads, to rotate. By having the fabric rotate with the support rod, wrinkles on the fabric surface are eliminated, preventing wrinkles from affecting the accuracy of air permeability testing. At the same time, the support rod and the pressure rod drive the two rotating pads to rotate, ensuring that the rotating pads and the fabric rotate at the same speed. This prevents wrinkles between the two rotating pads when they hold the fabric.

[0014] 3. This invention utilizes the cooperation between protruding strip one, protruding strip two, and the spring top block. After the spring top block and protruding strip one come into contact with each other, the support rod moves rapidly upward following the pressure rod. When the spring top block moves away from protruding strip one and comes into contact with protruding strip two, the pressure rod drives the support rod to move rapidly downward. Through the pressure rod and the support rod, the fabric moves up and down rapidly, causing the fabric to shake during rotation. This shaking cleans the dust and stains attached to the fabric surface, further improving the accuracy of air permeability testing. Attached Figure Description
