Description

Technical Field

[0001] The invention relates to the technical field of fabric equipment, and in particular to a device for testing the windproof performance of textile fabrics. Background Art

[0002] Textile fabrics, also known as textile fiber fabrics, are surface materials composed of textile fibers. Specifically, textile fibers are formed into fabrics with certain shapes and properties through processes such as spinning and weaving. These fabrics are textile fabrics. This kind of fabric is widely used in many fields such as clothing, home decoration, and industrial fabrics. The sources of textile fibers are varied, including natural fibers and artificial fibers. Natural fibers can be plant fibers (such as cotton, hemp, etc.), animal fibers (such as wool, silk, etc.) or mineral fibers (such as asbestos). Artificial fibers are mainly chemical fibers, such as polyester fibers, nylon, acrylic fibers, etc. These fibers are manufactured by chemical methods and have specific properties and uses. Textile fabrics not only have basic functions such as covering and keeping warm, but with the development of technology, current fabrics also have a variety of special properties, such as waterproof, breathable, flame retardant, antistatic, etc., to meet different occasions and needs.

[0003] A woven fabric windproof performance test device for a knitting factory with application number CN201721807807.1 includes a test box, a base, a test probe, a magnet sheet, a mounting cover, a motor and a telescopic tube, wherein a test box is provided on one side of the upper end of the base, a bellows is provided on the other side of the upper end of the base, a one-way air outlet is provided on the side of the test box away from the bellows, and a test through hole is provided on the other side of the test box. The beneficial effects of the present invention are as follows: the present invention controls the motor to generate wind through a PLC controller, and the airflow is blown toward the fabric through the telescopic tube. When airflow passes through the fabric, the test probe detects it and displays the test structure on a display screen for easy observation.

[0004] The above patent document has the beneficial effect that the fabric to be tested is placed on a fixed seat, covered with a mounting cover, and air leakage is prevented by an elastic sealing gasket. The magnet sheet at one end of the mounting cover adsorbs the iron sheet on the telescopic tube to fix it, and the telescopic tube is pulled, and the magnet sheet adsorbs the iron sheet on the surface around the detection through hole to fix it. The installation is easy and portable. However, the above patent can only test one fabric at a time. When multiple fabrics need to be tested, the fabrics need to be replaced multiple times, which greatly reduces the efficiency of the test. In addition, the fabric clamping of the above patent document is only connected by the mounting cover and the magnet. The connection method is relatively simple and easy to detach when the wind is strong. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the above-mentioned existing patent can only test one fabric at a time. When multiple fabrics need to be tested, the fabrics need to be replaced multiple times, which greatly reduces the test efficiency. In addition, the fabric clamping of the above-mentioned patent document is only connected by a mounting cover and a magnet, and the connection method is relatively simple and easy to detach when the wind is strong. A windproof performance testing device for textile fabrics is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A device for testing the windproof performance of textile fabrics, comprising a base plate placed on the ground, a fan box fixedly connected to the top of the base plate, evenly distributed bellows fixedly connected to the bottom end of the inner wall of the bellows box, the bellows connected to a slide plate via a multiple blowing structure, a duct box fixedly connected to the top of the base plate, evenly distributed air ducts are arranged inside the duct box, a test box is fixedly connected to the outer wall of the duct box, a slot is provided at the top of the test box, and a fabric mounting plate is connected to the inner wall of the slot via a sliding clamping structure.

[0008] Preferably, the multiple air blowing structure includes a motor, fan blades, a slide rail, an air outlet, a wind shield, and a handle that are evenly distributed. The motor is fixedly connected to the inner wall of the bellows, and the fan blades are fixedly connected to the output end of the motor.

[0009] Preferably, the slide rail is arranged at the bottom end of the inner wall of the fan box, the air outlet is arranged on the outer wall of the slide plate, the wind shield is slidably connected to the top of the slide plate, and the handle is fixedly connected to the outward end of the slide plate.

[0010] Preferably, a wind force detector is fixedly connected to the top of the outer wall of the air duct, and one end of the air duct facing the fan box is connected to the fan box.

[0011] Preferably, a test cavity is provided inside the test box, a ventilation plate is fixedly connected to the middle end of the inner wall of the test cavity, and an air outlet scoop is connected through one end of the test box facing outward.

[0012] Preferably, a wind speed tester is fixedly connected to one end of the air-permeable plate facing the fan box, and a distance detector is fixedly connected to the inner wall of the test cavity.

[0013] Preferably, the sliding clamping structure includes evenly distributed adapter grooves, protrusions, air vents, fabric, fabric stoppers, bottom plug posts, limiting holes, sliding holes, springs, limiting blocks, and fixed posts. The inner wall of the slot is provided with symmetrically distributed adapter grooves. The protrusion is fixedly connected to the outer wall of the fabric mounting plate. The air vent is arranged at the middle end of the outer wall of the fabric mounting plate, and the fabric is slidably connected to the air vent.

[0014] Preferably, the fabric stopper is slidingly connected to the air vent, the bottom plug column is fixedly connected to the inner wall of the fabric mounting plate, the limiting hole is arranged on the outer wall of the fabric stopper, the sliding hole is arranged inside the fabric mounting plate, one end of the spring is fixedly connected to the inner wall of the sliding hole, the limiting block is slidingly connected to the inner wall of the sliding hole, and the bottom end of the fixed column is fixedly connected to the top end of the limiting block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the present invention is in use, multiple bellows, motors, fan blades and air ducts can be coordinated to test multiple fabrics at the same time. The wind speed can be adjusted between multiple motors to facilitate comparative testing. The sliding slide, air vents and wind shields can block the air ducts when other air ducts are not in use, thereby preventing the dispersion of wind force from affecting the test results. Thus, multiple fabrics can be tested at the same time without the need to replace the fabrics multiple times, and the test efficiency is greatly improved.

[0017] 2. When the present invention is in use, the cloth stopper can squeeze and limit the cloth placed in the vent to prevent it from being blown away through the cooperation between the cloth stopper, the limit block and the limit hole on the fabric installation plate. At the same time, the fixing column and the spring, the limit hole and the bottom plug column can cooperate so that when the fixing column is moved up and down, the limit block can be driven to move up and down accordingly. When the limit block is away from the limit hole on the cloth stopper, it can be taken out and replaced. Therefore, while the cloth stopper performs friction blocking, the limit structure is added to make the connection tighter and will not be easily detached when the wind is strong.

[0026] Reference Figure 1-Figure 6 A device for testing the windproof performance of a textile fabric comprises a base plate 1 placed on the ground, a fan box 2 is fixedly connected to the top of the base plate 1, and evenly distributed wind boxes 3 are fixedly connected to the bottom end of the inner wall of the wind box 2, and the wind box 3 is connected to a slide plate 4 through a multiple blowing structure, a duct box 5 is fixedly connected to the top of the base plate 1, and evenly distributed wind ducts 6 are arranged inside the duct box 5, and a test box 7 is fixedly connected to the outer wall of the duct box 5, and a slot 8 is opened at the top of the test box 7, and the inner wall of the slot 8 is connected to a fabric mounting plate 9 through a sliding clamping structure.

[0027] It should be noted that the specific models and specifications of the motor 10, wind force detector 16, wind speed tester 20, and distance detector 21 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0028] Furthermore, the multiple blowing structure includes a uniformly distributed motor 10, fan blades 11, a slide rail 12, an air outlet 13, a wind shield 14, and a handle 15. The motor 10 is fixedly connected to the inner wall of the bellows 3, and the fan blades 11 are fixedly connected to the output end of the motor 10.

[0029] Among them, the multiple blowing structure is to start the motor 10, the motor 10 drives the fan blades 11 to rotate, and distinguish different wind speeds according to the rotation speed of the motor 10, and then use the handle 15 to move the slide plate 4 out of the slide rail 12, and then take out the wind shield 14 according to the amount of cloth 25 tested as needed, and then insert the slide plate 4 into the slide rail 12, and the wind generated by the fan blades 11 is blown into the air duct 6 through the air outlet 13.

[0033] The air duct 6 is fixedly connected to the outer wall of the fan box 2 without air leakage. The wind force detector 16 arranged on the outer wall of the air duct 6 can observe the wind speed of the air duct 6 at this time, which is convenient for comparative observation.

[0034] Furthermore, a test cavity 17 is provided inside the test box 7 , a ventilation plate 18 is fixedly connected to the middle end of the inner wall of the test cavity 17 , and an air outlet scoop 19 is connected through one end of the test box 7 facing outward.

[0035] The functions of the air vent plate 18 and the air outlet 19 are to discharge the wind that has passed through the fabric 25 from the inside of the test box 7, so as to avoid damage to the test device due to the large difference in wind pressure between the inside and outside, thereby affecting the test effect.

[0036] Furthermore, a wind speed tester 20 is fixedly connected to one end of the air-permeable plate 18 facing the fan box 2 , and a distance detector 21 is fixedly connected to the inner wall of the test cavity 17 .

[0037] Among them, the function of the wind speed tester 20 is to detect the wind speed after passing through the fabric 25, and the function of the distance detector 21 is to detect the deformation degree of the fabric 25 deformed by the wind, so as to facilitate the calculation of air permeability. The real-time data of the two can be recorded and collected by an external computer.

[0038] Furthermore, the sliding clamping structure includes evenly distributed adapter grooves 22, protrusions 23, vents 24, fabric 25, fabric stoppers 26, bottom plug posts 27, limiting holes 28, sliding holes 29, springs 30, limiting blocks 31, and fixed posts 32.

[0039] Among them, the above-mentioned is the clamping part in the sliding clamping structure, which is achieved by placing the cloth 25 on the larger inner wall of the air vent 24, the cross-section of the air vent 24 is convex, and then inserting the cloth stopper 26 into the larger mouth of the air vent 24, and clamping the cloth 25 between the cloth stopper 26 and the air vent 24.

[0040] Furthermore, the fabric stopper 26 is slidingly connected to the vent 24, the bottom plug post 27 is fixedly connected to the inner wall of the fabric mounting plate 9, the limiting hole 28 is arranged on the outer wall of the fabric stopper 26, the sliding hole 29 is arranged inside the fabric mounting plate 9, one end of the spring 30 is fixedly connected to the inner wall of the sliding hole 29, the limiting block 31 is slidingly connected to the inner wall of the sliding hole 29, and the bottom end of the fixing post 32 is fixedly connected to the top end of the limiting block 31.

[0041] Among them, the above is the limiting part in the sliding clamping structure, which is slidably connected with the bottom plug column 27 through the bottom end of the cloth stopper 26, and then the fixing column 32 is pushed upward to drive the limiting block 31 to move upward in the sliding hole 29 while squeezing the spring 30. When the limiting block 31 completely enters the sliding hole 29, the cloth stopper 26 is installed in the air vent 24, and then the fixing column 32 is released. Under the elastic action of the spring 30, the limiting block 31 returns to its original position and is slidably connected with the limiting hole 28 to prevent the cloth baffle 26 from being blown out of its original position by strong wind. Finally, the fabric mounting plate 9 is aligned with the slot 8, and the protrusion 23 is aligned with the adapter slot 22 for insertion.

[0042] Working principle: first, put the textile fabric to be tested into the fabric installation plate 9, that is, put the fabric 25 at the larger inner wall of the air vent 24, the cross-section of the air vent 24 is convex, and then insert the fabric stopper 26 into the larger mouth of the air vent 24, clamp the fabric 25 between the fabric stopper 26 and the air vent 24, and then slide and connect it with the bottom plug post 27 through the bottom end of the fabric stopper 26, and then push the fixing post 32 upward to drive the limit block 31 to move upward while squeezing the spring 30 in the sliding hole 29. When the limit block 31 completely enters the sliding hole 29, install the fabric stopper 26 into the air vent 24, and then release the fixing post 32. Under the elastic action of the spring 30, the limit block 31 returns to its original position and is slidably connected with the limit hole 28 to prevent the fabric baffle 26 from being blown out of its original position by strong wind. Finally, align the fabric installation plate 9 with the slot 8, and align the convex block 23 with the adapter slot 22 for insertion.

[0043] After completing the installation of the textile fabric, the motor 10 can be started, and the motor 10 drives the fan blades 11 to rotate. Different wind speeds are distinguished according to the rotation speed of the motor 10, and then the slide plate 4 is taken out of the slide rail 12 through the handle 15. Then, according to the number of test fabrics 25 required, the wind shield 14 is taken out, and then the slide plate 4 is inserted into the slide rail 12. The wind generated by the fan blades 11 is blown into the air duct 6 through the air outlet 13. The air duct 6 is coaxially connected to the fabric installation plate 9. The fabric is tested, and the windproof performance is obtained by cumulative calculation of the data of the wind force detector 16, the wind speed tester 20 and the distance detector 21, so that multiple fabrics can be tested at the same time, and there is no need to replace the fabrics multiple times. The test efficiency is therefore greatly improved. In addition, while the fabric block is frictionally blocked, a limiting structure is added to make the connection tighter and it will not be easily detached when the wind is strong.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
