Description

Technical Field

[0001] The utility model relates to the technical field of fabric air permeability detection, in particular to an air permeability testing device for silk fabrics. Background Art

[0002] When the existing air permeability testing device for silk fabrics is in operation, a significant limitation is that it requires the fabric to be pre-clamped above the device before the air permeability performance can be tested. This clamping process not only increases the complexity of the operation but also directly leads to a slowdown in the detection speed, thus affecting the overall detection efficiency. In addition, the current testing device is often limited in design to detecting a fixed position of the silk fabric and lacks flexible and variable testing capabilities. This limitation makes it impossible to comprehensively cover different areas of the fabric when evaluating the overall air permeability performance of the fabric, especially those positions that may vary due to factors such as weaving process and material distribution. Therefore, the test results may not truly reflect the overall air permeability performance of the silk fabric, thereby affecting the detection accuracy and subsequent product quality control decisions. Hence, we have proposed an air permeability testing device for silk fabrics. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide an air permeability testing device for silk fabrics, which can effectively solve the problems in the background art.

The middle parts and the rear parts of the outer surfaces of the two electric push rods are respectively inserted and movably connected with the rear frame walls of the two support frames and the rear cover wall of the protective cover through bearings. By adopting the above technical solution: Through the cooperation of the synchronization mechanism and the drive of the driver, the synchronous rotation of the two fabric winding and unwinding rollers can be realized.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] A silk fabric breathability testing device, including a testing box 1. The lower part of the front end of the testing box 1 is movably connected with a sealing door 2 through a hinge. The four corners of the lower end of the testing box 1 are fixedly connected with support feet 3. The upper part of the front end of the testing box 1 is fixedly connected with a controller 4. The upper parts of the left and right box walls of the testing box 1 are both provided with inlets and outlets 5.

[0026] The upper part of the front end of the right support frame 7 is provided with a driver 9, and the output end of the driver 9 penetrates through the front wall of the right support frame 7 and is fixedly connected with the front end of the right first fixing block 8. The rear parts of the outer surfaces of the two first fixing blocks 8 are both clamped with fabric winding and unwinding rollers 10. A synchronization mechanism 11 is movably inserted between the upper parts of the rear walls of the two support frames 7, and a protective cover 12 is movably inserted through the rear end of the synchronization mechanism 11.

[0027] In this embodiment, the synchronization mechanism 11 includes electric push rods 111, and there are two electric push rods 111. Synchronization wheels 112 are respectively and fixedly connected to the rear parts of the outer surfaces of the two electric push rods 111 in an inserted manner. A synchronization belt 113 is commonly sleeved between the middle parts of the outer surfaces of the two synchronization wheels 112. The output ends of the two electric push rods 111 are fixedly connected with second fixing blocks 114. The middle parts and the rear parts of the outer surfaces of the two electric push rods 111 are respectively and movably connected to the rear wall of the two support frames 7 and the rear cover wall of the protective cover 12 in an inserted manner through bearings; the electric push rods 111 and the driver 9 are both electrically connected to the controller 4. Polygonal blocks are arranged on the opposite surfaces of the second fixing blocks 114 and the first fixing blocks 8; polygonal card slots are respectively formed in the front end and the rear end of the fabric winding and unwinding roller 10. The support frame 7 is arranged in an inclined structure, and the outer surface of the guide roller 6 does not contact the inner wall of the inlet and outlet 5.

[0028] By the above solution: First, the fabric winding and unwinding roller 10 with a roll of silk fabric is clamped on the first fixing block 8, and then the electric push rod 111 extends to push the second fixing block 114 forward, so that the second fixing block 114 is inserted into the fabric winding and unwinding roller 10 to clamp and fix it, so as to realize the rapid clamping of a roll of silk fabric, and it is also convenient to perform air permeability detection on a roll of silk fabric. Then, the driver 9 drives the fabric winding and unwinding roller 10 on the right side to rotate, and through the synchronous transmission between the synchronous belt 113 and the two synchronous wheels 112, the fabric winding and unwinding roller 10 on the left side can be driven to rotate together. One side can unwind a roll of silk, and the other side can wind up the released silk fabric, so that the detection speed can be increased by the winding and unwinding of the silk fabric, the overall testing efficiency of the testing device is improved, and the operation of the testing device is made more concise.

[0029] In this embodiment, filter nets 13 are respectively and fixedly connected to the left part and the right part of the lower box wall of the test box 1 in an inserted manner. Four electric telescopic rods 14 are fixedly connected to the middle part of the lower box wall of the test box 1. An air outlet cover 15 is fixedly connected among the output ends of the four electric telescopic rods 14 in an inserted manner. An air pump 16 is fixedly connected to the middle part of the lower end of the air outlet cover 15 in an inserted manner. A test tube 17 is fixedly connected to the middle part of the upper box wall of the test box 1 in an inserted manner. A pressure sensor 18 is fixedly connected to the middle part of the right end of the test tube 17 in an inserted manner; the electric telescopic rods 14, the air pump 16 and the pressure sensor 18 are all electrically connected to the controller 4. A dust filter cover is threadedly connected to the lower part of the outer surface of the air pump 16. The test tube 17 is located directly above the air outlet cover 15.

[0030] Through the above solution: First, start the electric telescopic rod 14 to make it extend and push the air outlet cover 15 upward, so that the air outlet cover 15 presses tightly against the upper box wall of the test box 1, thereby limiting and fixing the test position of the silk fabric. Then, start the air pump 16 to generate suction, so that the air passes through the filter screen 13 and the filter cover on the air pump 16 to filter out dust, and then blows the air to the silk fabric through the air outlet cover 15, so that the air passes through the silk fabric and enters the test tube 17. The air pressure sensor 18 monitors the air pressure value in the test tube 17 in real time, and the air permeability of the silk fabric can be tested through the air pressure value. During the test, by feeding and rewinding the silk fabric, the test position of the silk fabric can be quickly changed, which is convenient for testing the air permeability of various parts of the silk fabric, enabling the test device to meet the test requirements and improve the detection accuracy.

[0031] It should be noted that during use, first, the fabric winding and unwinding roller 10 with a roll of silk fabric is stuck on the first fixing block 8, and the other fabric winding and unwinding roller 10 is stuck on another first fixing block 8. Then, both fabric winding and unwinding rollers 10 are installed and fixed through the synchronization mechanism 11, which can realize the quick clamping of a roll of silk fabric. One end of the roll of silk fabric passes through the left import and export 5 and enters the test box 1, and then passes through the right import and export 5 and is fixed on the right fabric winding and unwinding roller 10. At this time, the controller 4 can be used to control the start of the electric telescopic rod 14 and the air pump 16, and the air permeability of the silk fabric entering the test box 1 can be tested. After the test is completed, the controller 4 controls the electric telescopic rod 14 to contract and controls the driver 9 to start, so that the driver 9 cooperates with the synchronization mechanism 11 to release the untested silk fabric while rewinding the tested silk fabric, and with the guidance of the guide roller 6, it is convenient to test the air permeability of different positions of the silk fabric, enabling the test device to have a flexible and variable test ability, so that the test results of this test method can truly reflect the overall air permeability of the silk fabric, thereby improving the detection accuracy and subsequent product quality control decisions.
