Description

Technical Field

[0001] This utility model relates to the field of fabric defect detection technology, and in particular to a device for detecting the air permeability of textile fibers after drying. Background Technology

[0002] Breathability refers to the permeability of gases through polymer materials such as films, coatings, and fabrics. It is one of the important physical properties of polymers and textiles. For textiles, the breathability of the fabric directly affects the comfort of use. If the breathability of the fabric is too low, it will make people feel stuffy and uncomfortable because the body's heat and moisture cannot be easily discharged. Different fabrics or different specifications of the same fabric have different breathability. Testing the breathability of the fabric before processing and production is helpful for the classification of the fabric.

[0003] The detection device typically places the sample between two chambers, with the upper chamber maintaining a higher pressure and the lower chamber a lower pressure. Gas permeates from the high-pressure side through the sample to the low-pressure side, and the volume or flow rate of gas passing through the sample per unit time is measured.

[0004] In existing technologies, some testing devices use the flow rate of gas permeation to detect the air permeability of fabrics during processing. However, this method requires removing the fabric for observation and waiting for the test results, which takes a long time and is inconvenient for timely adjustments based on the test results. Therefore, a textile fiber air permeability testing device after drying is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a textile fiber air permeability testing device after drying, which aims to improve the problems in the existing technology that require taking the fabric out for observation, waiting for the test results, and having a long testing time, making it inconvenient to make timely adjustments based on the test results.

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

[0007] A textile fiber air permeability testing device after drying includes a testing platform. An air pump is fixedly connected to the front exterior of the testing platform, and a connecting pipe is fixedly connected to the drive end of the air pump. An air inlet pipe is fixedly connected to the interior of the testing platform, and the other end of the connecting pipe is fixedly connected to the interior of the air inlet pipe. A cavity is formed inside the air inlet pipe, and a piston is slidably connected to the inner wall of the cavity. A counterweight is slidably connected to the top of the piston. A connecting frame is fixedly connected to the exterior of the testing platform, and a fixing component is provided inside the connecting frame to prevent the fabric from moving. A fixing frame is fixedly connected to the top of the testing platform, and an adjustment component is provided outside the fixing frame to prevent the fabric from breaking.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes an air inlet pipe, which is externally fixedly connected to the middle of the connecting frame. Two electric push rods are internally fixedly connected to the connecting frame, and pressure plates are fixedly connected to the drive ends of the two electric push rods.

[0010] As a further description of the above technical solution:

[0011] The top of the counterweight is fixedly connected to a base, the outside of the air inlet pipe is slidably connected to the inner wall of the base, the outside of the air inlet pipe is slidably connected to the inside of the pressure plate, and the outside of the fixing frame is fixedly connected to a connecting plate.

[0012] As a further description of the above technical solution:

[0013] The adjustment assembly includes multiple telescopic columns, each telescopic column is fitted with a spring, and a mounting base is fixedly connected to the side of the telescopic column away from the connecting plate, wherein a connecting rod is fixedly connected to the adjacent side of two of the mounting bases.

[0014] As a further description of the above technical solution:

[0015] One end of the spring is fixedly connected to the outside of the telescopic column, and the other end of the spring is fixedly connected to the outside of the mounting base.

[0016] As a further description of the above technical solution:

[0017] The connecting plate has a square groove inside, and a rubber ball is detachably connected to the top of the air inlet pipe;

[0018] As a further description of the above technical solution:

[0019] The outer left side of the testing station is fixedly connected to a connecting frame, and a feeding roller is rotatably connected to the outside of the connecting frame.

[0020] As a further description of the above technical solution:

[0021] A connecting frame two is fixedly connected to the outer right side of the testing platform. A motor is fixedly connected to the front end of the connecting frame two, and a take-up roller is rotatably connected to the outside of the connecting frame two.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by starting the air pump, air is blown into the air inlet pipe through the connecting pipe under the drive of the air pump. After the gas enters the interior of the cavity, it lifts the piston and the counterweight. When the fabric passes the bottom of the air inlet pipe, the electric push rod is activated. At this time, the gas passes through the fabric and enters the interior of the air inlet pipe. At the same time, it will cause the rubber ball to expand, which allows for timely observation of the air permeability of the fabric and facilitates the recording of test results for different areas of the same piece of fabric.

[0024] 2. In this utility model, by starting the motor, the winding roller winds up the fabric under the drive of the motor. The fabric moves from the outside of the unloading roller and passes through the connecting rod. The elasticity of the spring can be used to adjust the tension of the fabric, so as to avoid breakage during winding and inspection. Attached Figure Description

[0031] 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.

[0032] Reference Figures 1 to 2This utility model provides an embodiment of a textile fiber air permeability testing device after drying, comprising a testing platform 1. The testing platform 1 serves as the basic supporting component of the entire device, providing a platform for the installation and operation of other components. An air pump 2 is fixedly connected to the front exterior of the testing platform 1. The air pump 2 is a key device providing gas power for the entire testing device. A connecting pipe 3 is fixedly connected to the drive end of the air pump 2, and an air inlet pipe 4 is fixedly connected inside the testing platform 1. The connecting pipe 3 acts as a bridge between the air pump 2 and the air inlet pipe 4, responsible for smoothly transmitting the compressed gas generated by the air pump 2 to the air inlet pipe 4.

[0033] The other end of the connecting pipe 3 is fixedly connected to the inside of the air inlet pipe 4. The air inlet pipe 4 is the channel for gas to enter the internal cavity 5 of the detection platform 1. The cavity 5 is located inside the air inlet pipe 4 and is a key space for gas pressure conversion and transmission. A piston 6 is slidably connected to the inner wall of the cavity 5. The piston 6 is a key component that moves up and down within the cavity 5 and fits tightly with the inner wall of the cavity 5 to form a sealed gas chamber. A counterweight 7 is slidably connected to the top of the piston 6. The main function of the counterweight 7 is to provide gravitational resistance during the movement of the piston 6, thereby controlling the movement speed of the piston 6.

[0034] The testing platform 1 is externally fixedly connected to a connecting frame 9, which serves to connect and support other components on the testing platform 1. The connecting frame 9 has an internal fixing component to prevent fabric movement. This component includes an air inlet pipe 10, which is a crucial channel for gas transmission, running through the connecting frame 9 and components such as the pressure plate 13. The air inlet pipe 10 is externally fixedly connected to the middle of the connecting frame 9. A base 8 is fixedly connected to the top of the air inlet pipe 4, serving as a support and guide for the counterweight 7, and is fixed to the top of the testing platform 1.

[0035] The air inlet pipe 10 is externally slidably connected to the inner wall of the base 8. A rubber ball 11 is detachably connected to the top of the air inlet pipe 10. The rubber ball 11 serves as a visual indicator of the fabric's air permeability and possesses good elasticity and sealing properties. Two electric push rods 12 are fixedly connected internally to the connecting frame 9. The drive ends of the two electric push rods 12 are fixedly connected to a pressure plate 13, which is the power source for controlling the up-and-down movement of the pressure plate 13. The air inlet pipe 10 is externally slidably connected to the inside of the pressure plate 13. The pressure plate 13, driven by the electric push rods 12, performs a squeezing operation on the fabric.

[0036] Reference Figures 3 to 4A fixed frame 14 is fixedly connected to the top of the testing platform 1. The fixed frame 14 provides stable support and guidance for the fabric transfer and testing process. A connecting plate 15 is fixedly connected to the outside of the fixed frame 14. The connecting plate 15 serves as the connecting component between the fixed frame 14 and the adjustment assembly, and plays the role of transmitting force and fixing the component. An adjustment assembly is provided on the outside of the fixed frame 14. The adjustment assembly can prevent fabric breakage. The adjustment assembly includes multiple telescopic columns 16. The telescopic columns 16 are fixedly connected to the upper and lower sides of the connecting plate 15 respectively. The telescopic columns 16 are the main support structure of the adjustment assembly, and generally consist of an inner rod and an outer tube. The inner rod can freely extend and retract within the outer tube.

[0037] A spring 17 is fitted around the outside of the telescopic column 16, serving as an elastic adjuster. A mounting base 18 is fixedly connected to the side of the telescopic column 16 furthest from the connecting plate 15. The weight of the fabric acts on the mounting base 18, causing it to shift and compress the spring 17. The fabric tension is adjusted by transmitting the displacement of the mounting base 18. A connecting rod 19 is fixedly connected to the adjacent sides of the two mounting bases 18, allowing the fabric to move smoothly. One end of the spring 17 is fixedly connected to the outside of the telescopic column 16.

[0038] The other end of the spring 17 is fixedly connected to the outside of the mounting base 18. A square groove 20 is provided inside the connecting plate 15, which allows the fabric to pass through smoothly. A connecting frame 1 21 is fixedly connected to the outside of the detection platform 1. A feeding roller 22 is rotatably connected to the outside of the connecting frame 1 21. A connecting frame 23 is fixedly connected to the outside of the detection platform 1. A motor 24 is fixedly connected to the front end of the connecting frame 23. A take-up roller 25 is rotatably connected to the outside of the connecting frame 23. The motor 24 provides power to the take-up roller 25, causing the take-up roller 25 to pull the fabric to move.

[0039] Working principle: First, place the detection table 1 in a suitable position, then start the motor 24. Driven by the motor 24, the take-up roller 25 takes up the fabric outside the feed roller 22. At this time, the fabric is pulled to the outside of the connecting rod 19. The weight of the fabric will squeeze the bottom mounting seat 18. At the same time, the mounting seat 18 will squeeze the spring 17 to compress it. When the spring 17 is compressed, it generates a reaction force on the mounting seat 18. The fabric comes into contact with the bottom connecting rod 19 through the square groove 20. Pressure will also be generated between the fixed frame 14 and the bottom connecting rod 19. The fabric will squeeze the bottom connecting rod 19, causing the bottom spring 17 to be compressed. The tension of the fabric is adjusted by its elasticity.

[0040] When the fabric passes the bottom of the pressure plate 13, the electric push rod 12 is activated. Driven by the electric push rod 12, the pressure plate 13 moves downward to squeeze the fabric. At the same time, the bottom of the air pipe 10 is aligned with the top of the base 8. Then the air pump 2 is activated. Driven by the air pump 2, the gas enters the air inlet pipe 4 through the connecting pipe 3. After the gas enters the cavity 5, it pushes the piston 6 upward to move. Under the gravity of the counterweight 7, the moving speed is slowed down. Then the gas continues to move upward through the fabric into the air pipe 10, thereby causing the rubber ball 11 to expand.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
