Description

Technical Field

[0001] This utility model relates to the field of fiber woven fabric technology, and in particular to a device for testing the air permeability of fiber woven fabric. Background Technology

[0002] Fiber woven fabric is a functional material that combines fiber raw materials with weaving technology. Its characteristics are determined by fiber properties, weaving density and structure. When selecting it, it is necessary to take into account the intended use, such as breathability, strength requirements and maintenance costs, such as whether it is prone to wrinkling and shrinkage.

[0003] Currently, when testing the air permeability of woven fabrics, the fabric needs to be clamped and fixed on the testing device. However, the position of the clamping mechanism on the testing device is fixed, which makes it impossible to clamp woven fabrics of different sizes, thus hindering the air permeability testing of woven fabrics of different sizes.

[0004] To address this issue, we propose a device for testing the air permeability of woven fiber fabrics. Utility Model Content

[0005] The purpose of this invention is to provide a device for testing the air permeability of woven fiber fabrics, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for testing the air permeability of woven fiber fabric includes a support plate, an adjustment mechanism on the outer surface of the support plate, a clamping mechanism on the outer surface of the adjustment mechanism, a fan fixedly connected to the outer surface of the support plate, an air outlet duct fixedly connected to the output end of the fan, an air inlet fixedly connected to the end of the air outlet duct away from the fan, a support base fixedly connected to the outer surface of the support plate, and a wind speed detector fixedly connected to the inner wall of the support base.

[0008] In a further embodiment, a fixing plate is fixedly connected to the outer surface of the support plate, a display panel is fixedly installed on the front side of the fixing plate, and a plurality of control buttons are fixedly installed on the front side of the fixing plate.

[0009] In a further embodiment, the adjustment mechanism includes a fixed base, the outer surface of which is fixedly connected to the outer surface of the support plate, a dual-axis motor fixedly connected to the inner wall of the fixed base, and lead screws fixedly connected to both output ends of the dual-axis motor. Two vertical plates are fixedly connected to the outer surface of the support plate.

[0010] In a further embodiment, bearings are fixedly embedded on the sides of the two vertical plates that are close to each other, the outer surfaces of the two lead screws are respectively fixedly connected to the inner rings of the two bearings, the outer surface of the support plate has two movable openings, and the outer surface of each lead screw is threaded with a support rod.

[0011] In a further embodiment, the clamping mechanism includes two clamping slots, which are respectively opened on the outer surfaces of two support rods. Each clamping slot has an opening on its inner wall. Each support rod has an electric push rod fixedly connected to its outer surface, and each electric push rod has a clamping plate fixedly connected to its output end.

[0012] In a further embodiment, each of the clamping slots has two positioning holes on its inner wall, and each of the clamping plates has two positioning rods fixedly connected to its outer surface. The inner walls of the four positioning holes are slidably connected to the outer surfaces of the four positioning rods, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device uses an adjustment mechanism to move the clamping mechanisms closer together or further apart, and clamps the woven fabric to hold it in place. This allows for the clamping and fixing of woven fabrics of different sizes, facilitating subsequent air permeability testing. A fan generates airflow, which is then directed to the woven fabric through an air outlet and blower. Finally, an airflow meter is used to measure the airflow through the woven fabric, enabling the air permeability testing of the fixed woven fabric. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4In this utility model, a device for testing the air permeability of woven fabric includes a support plate 1, an adjustment mechanism 2 on the outer surface of the support plate 1, a clamping mechanism 3 on the outer surface of the adjustment mechanism 2, a fan 4 fixedly connected to the outer surface of the support plate 1, an air outlet duct 5 fixedly connected to the output end of the fan 4, an air inlet 6 fixedly connected to the end of the air outlet duct 5 away from the fan 4, a support base 7 fixedly connected to the outer surface of the support plate 1, a wind speed detector 8 fixedly connected to the inner wall of the support base 7, a fixing plate 9 fixedly connected to the outer surface of the support plate 1, and a display panel 10 fixedly mounted on the front of the fixing plate 9. Several control buttons 11 are fixedly installed on the front. The fan 4 can generate wind power, which is discharged through the air outlet duct 5 and the blower 6 and then directed towards the fixed fiber woven fabric. Some of the wind power will pass through the fabric. The wind power detector 8 is used to detect the passing wind power, thereby realizing the detection of the air permeability of the fiber woven fabric. The support base 7 supports the wind power detector 8 to increase the stability of the wind power detector 8. The display panel 10 displays the results detected by the wind power detector 8, so that personnel can directly know the results. The control buttons 11 can operate the device to facilitate its operation.

[0024] The adjustment mechanism 2 includes a fixed base 201, the outer surface of which is fixedly connected to the outer surface of the support plate 1. A dual-axis motor 202 is fixedly connected to the inner wall of the fixed base 201. A lead screw 203 is fixedly connected to each of the two output ends of the dual-axis motor 202. Two vertical plates 204 are fixedly connected to the outer surface of the support plate 1. Bearings 205 are fixedly embedded on the side of the two vertical plates 204 that are close to each other. The outer surfaces of the two lead screws 203 are fixedly connected to the inner rings of the two bearings 205 respectively. Two moving openings 206 are opened on the outer surface of the support plate 1. A support rod 207 is threadedly connected to the outer surface of each lead screw 203. The dual-axis motor 202 can drive the lead screw 203 to rotate. The rotation of the lead screw 203 drives the support rod 207 to move, which in turn drives the clamping mechanism 3 to move, thereby adjusting the distance between the clamping mechanisms 3, so that the clamping mechanism 3 can clamp and fix fabrics of different sizes.

[0025] The clamping mechanism 3 includes two clamping slots 301, which are respectively formed on the outer surfaces of two support rods 207. Each clamping slot 301 has an opening 302 on its inner wall. An electric push rod 303 is fixedly connected to the outer surface of each support rod 207. A clamping plate 304 is fixedly connected to the output end of each electric push rod 303. Two positioning holes 305 are formed on the inner wall of each clamping slot 301. Two positioning rods 306 are fixedly connected to the outer surface of each clamping plate 304. The four positioning rods... The inner wall of the positioning hole 305 is slidably connected to the outer surface of the four positioning rods 306 respectively. The electric push rod 303 in the clamping mechanism 3 drives the clamping plate 304 to move, which can clamp and fix the fabric. When the electric push rod 303 drives the clamping plate 304 to move, the clamping plate 304 will drive the positioning rods 306 to move in the positioning hole 305, ensuring the stable movement of the clamping plate 304 and improving the clamping effect on the fabric. The clamped fabric needs to be flat. If the fabric is folded, it will affect the test of the fabric's air permeability.

[0026] The working principle of this utility model is as follows:

[0027] First, the adjusting mechanism 2 drives the clamping mechanism 3 above to move, and then the clamping mechanism 3 is adjusted to be suitable for clamping the fabric. Next, the clamping mechanism 3 clamps and fixes the fabric. After clamping and fixing, the fan 4 generates air force, and through the cooperation of the air outlet duct 5 and the blower 6, the generated air force is directed towards the fixed fiber woven fabric. Then, the wind force detector 8 is used to detect the air force passing through the fabric, thereby realizing the test of the air permeability of the fiber woven fabric.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
