Description

Technical Field

[0001] The invention belongs to the technical field of fabric performance detection devices, and in particular relates to a nylon fabric impact wear performance detection device and method. Background Art

[0002] Compared with pure cotton fabric, nylon fabric has high strength and good wear resistance, and is a commonly chosen fabric for sports and outdoor clothing. In order to ensure the wearing performance of nylon fabric, corresponding impact and wear performance testing items are required during its research and development and production.

[0003] The impact and wear performance test of clothing fabrics is to evaluate its performance when subjected to impact and wear by subjecting the fabrics to specific impact and wear tests. Specifically, the fabrics are fixed on the test platform and subjected to multiple impacts and frictions by the impact block, and then the impact and wear performance is evaluated according to the damage of the fabrics. However, since the test environment of the test equipment cannot be different from the actual wearing environment, the test results and the actual wearing effect are deviated. In view of the existence of the above problems, patent number CN118641400A discloses a method and equipment for testing the impact and wear performance of clothing fabrics, which can adjust the hardness of the test platform according to the test requirements, so that the fabrics can be tested according to the actual use conditions, and the accuracy of the fabric impact and wear test is improved. In fact, the performance of the fabrics under different wearing conditions, such as tight or loose conditions, when subjected to external impact or wear is also different. In addition, the current test of the impact and wear performance of fabrics is generally carried out by cutting fabric fragments for multiple repetitive test operations, which cannot continuously realize the performance test of the fabrics to be tested, and the efficiency is low and the application effect is poor.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Example 1

[0032] This embodiment provides a nylon fabric impact wear performance detection device, including a frame 1;

[0033] The device structure also includes a fabric feeding and receiving roller group 3 and a guide drum 4 for conveying the fabric to be tested, which are arranged at both ends of the frame 1. The fabric feeding and receiving roller group 3 is a component for conveying fabrics well known to those skilled in the art, and its structure includes a roller carrying the fabric to be tested and a transmission structure for driving the roller to rotate, such as Figure 1 As shown, in this embodiment, the installation positions of the two rollers of the fabric feeding and receiving roller group 3 are located at one end of the frame 1 and the two are on the same horizontal line. The guide drum 4 is located at the other end of the frame 1, and is used to receive and guide the fabric to be tested. The part where the fabric to be tested bypasses the guide drum 4 is used as the part for impact wear performance detection.

[0034] The device structure also includes a fabric positioning unit 5 arranged on the outside of the guide drum 4 for positioning the fabric to be tested. In the present embodiment, the fabric positioning unit 5 includes a positioning rod 51 arranged on the guide drum 4 near the input end and the output end of the fabric to be tested. An anti-slip portion 57 is provided on the inner side of the positioning rod 51. The fabric to be tested passes through the gap between the positioning rod 51 and the guide drum 4. The positioning rod 51 can fix the fabric to be tested on both sides of the guide drum 4.

[0035] The structure of the device also includes an impact wear detection unit 2 arranged near the guide drum 4 for performing impact wear detection on the fabric to be tested transmitted through the guide drum 4. The impact wear detection unit 2 in this embodiment is a detection device well known to those skilled in the art, which can realize impact testing and wear testing on the fabric to be tested.

[0036] Specifically, Figure 2 As shown, the guide drum 4 is provided with an adjustment unit, and the end of the guide drum 4 close to the fabric to be tested is a movable structure. The structure of the guide drum 4 includes a mounting seat 41, a rotating shaft 43 penetrating the middle of the mounting seat 41, and a shield 44 arranged on one side of the mounting seat 41. The movable structure is an adjustment roller 42 eccentrically arranged on the rotating shaft 43. When in use, when the adjustment roller 42 is not adjusted, its outer side surface is on the same horizontal line as the outer side of the mounting seat 41. At this time, the fabric to be tested is close to the outer side of the adjustment roller 42, and the two sides are fixed by positioning rods 51. At this time, the close-fitting wearing state of the fabric to be tested can be simulated. After the rotation shaft 43 is controlled by an external driving source to rotate 180°, the adjustment roller 42 is driven to rotate 180°. Since the adjustment roller 42 is eccentrically arranged on the rotating shaft 43, the radius of the adjustment roller 42 on the side of the fabric to be tested becomes smaller, and the adjustment roller 42 is not close to the fabric to be tested. At this time, the loose wearing state of the fabric to be tested can be simulated.

[0037] Example 2

[0038] In order to ensure that the gap distance between the fabric to be tested and the adjusting roller 42 can be adjusted according to the detection requirements, further Figure 2 As shown, the adjusting roller 42 is provided with an adjusting groove, and the outer side of the rotating shaft 43 is provided with a plurality of piston rods 48 that are movably matched with the adjusting groove. The adjusting unit includes connecting pieces 47 provided at the upper and lower ends of the adjusting roller 42, a telescopic cylinder 46 whose piston end is connected to the connecting piece 47, and a sleeve 45 that fixes the telescopic cylinder 46, and the sleeve 45 is sleeved on the rotating shaft 43. When in use, the telescopic cylinder 46 drives the connecting piece 47 to push the adjusting roller 42 to adjust its position in the adjusting groove, thereby changing the relative installation position of the adjusting roller 42 and the rotating shaft 43. At this time, after the rotating shaft 43 is controlled to rotate 180° by an external driving source, the radius reduction amount of the adjusting roller 42 toward the side of the fabric to be tested can be adjusted, that is, the gap distance between the adjusting roller 42 and the fabric to be tested can be adjusted. Such a design can further refine the degree of loose wearing state during fabric testing.

[0039] Example 3

[0040] On the basis of Example 1, in order to further ensure the positioning effect of the two positioning rods 51 on the fabric to be tested on both sides of the guide drum 4, as shown in FIG. Figure 1As shown, the fabric positioning unit 5 also includes a fan-shaped gear rod 53 arranged at the top of the positioning rod 51, a linkage gear rod 54 that is transmission-matched with the tooth portion of the fan-shaped gear rod 53, a mounting plate 56 that fixes the linkage gear rod 54, and a telescopic cylinder 2 55 whose piston end is connected to the mounting plate 56. The middle part of the fan-shaped gear rod 53 is axially connected to the frame 1, and the upper and lower ends of the frame 1 are provided with limit grooves 52 for the positioning rod 51 to move. When in use, the linkage gear rod 54 is driven to move horizontally by the telescopic cylinder 2 55, and the linkage gear rod 54 is transmission-matched with the tooth portion of the fan-shaped gear rod 53, which drives the fan-shaped gear rod 53 to swing and causes the positioning rod 51 connected to its other end to slide in the limit groove 52. In the process of the two positioning rods 51 approaching each other, the fabrics to be tested on both sides of the guide drum 4 are tightened, thereby improving the positioning effect.

[0041] Example 4

[0042] On the basis of Example 1, Figure 3-4 As shown, the structure of the impact wear detection unit 2 includes a detection host 21, a multi-axial translation unit 22 arranged on the detection host 21, and an impact wear detection component arranged on the multi-axial translation unit 22, wherein the multi-axial translation unit 22 can realize the position adjustment of the impact wear detection component in the horizontal and vertical directions, specifically, it can be a combination of multiple linear motors.

[0043] The impact wear detection assembly includes a base 23, a driving unit 25, an impact detection head 29 and a mounting frame 24 arranged on the base 23. The shape of the end of the mounting frame 24 that is not connected to the base 23 is adapted to the guide drum 4 and is symmetrically provided with a lifting rod 26 and a rotating rod 27 driven to rotate by the driving unit 25. A wear detection head 28 is provided on the lifting rod 26 and the rotating rod 27. The lifting rod 26 is a screw-nut assembly in this embodiment. The wear detection head 28 is connected to the screw through a nut. The nut and the screw are threadedly matched. By driving the screw to rotate, the nut drives the wear detection head 28 to achieve lifting and lowering displacement.

[0044] In this embodiment, the driving unit 25 includes a driving motor 251, a transmission wheel group 252, a bevel gear group 1 253, a transmission shaft 254 and a bevel gear group 2 255. The transmission wheel group 252 connects the two transmission shafts 254. The transmission wheel group 252 is preferably a pulley group. The driving shaft of the driving motor 251 is connected to a bevel gear of the bevel gear group 1 253. The other bevel gear of the bevel gear group 1 253 is connected to one of the transmission shafts 254. The bevel gear group 255 is two transmissions respectively used for transmission between one transmission shaft 254 and the lifting rod 26 and the other transmission shaft 254 and the rotating rod 27. When used, the driving motor 251 drives the bevel gear group 1 253 to rotate and then drives one transmission shaft 254 to rotate. After the transmission shaft 254 rotates, it drives the other transmission shaft 254 to rotate through the transmission wheel group 252. After the two transmission shafts 254 rotate, they respectively drive the lifting rod 26 and the rotating rod 27 to rotate through the bevel gear group 2 255.

[0045] When the impact wear detection unit 2 is used, the multi-axial translation unit 22 is first used to adjust the impact wear detection component to move in the vertical direction, so that the impact wear detection component is adjusted to a suitable test height, and then the multi-axial translation unit 22 is used to adjust the impact wear detection component to move in the horizontal direction so that it contacts the fabric to be tested on the guide drum 4. Subsequently, the driving unit 25 drives the lifting rod 26 and the rotating rod 27 to rotate back and forth. At this time, the lifting rod 26 rotates and drives the wear detection head 28 to move back and forth in the vertical direction to achieve a vertical movement wear test on the fabric to be tested. In addition, after the rotating rod 27 rotates, it drives the wear detection head 28 to reciprocate at a fixed point to achieve a fixed-point wear test. At the same time, the impact detection head 29 provided on the base 23 realizes the impact test of the fabric to be tested. It can be seen that the impact wear detection component provided in this embodiment can simultaneously realize a variety of different test forms, and the impact wear test for the fabric is more comprehensive.

[0046] Example 5

[0047] Based on Example 1, this embodiment provides a method for testing the impact and wear performance of nylon fabric using any of the above-mentioned devices, comprising the following steps:

[0048] Step 1: The fabric to be tested is input from the feeding end of the fabric feeding and receiving roller group 3, and is output from the receiving end of the fabric feeding and receiving roller group 3 after being guided by the guide drum 4, thereby completing the feeding of the fabric to be tested;

[0049] Step 2: first use the fabric positioning unit 5 to position the fabric to be tested at both ends of the guide drum 4, then use the adjustment unit to drive the active structure to fit closely with the fabric to be tested, simulating the close-fitting wearing state of the fabric to be tested, and then use the impact wear detection unit 2 to simulate the impact wear detection process of the fabric to be tested in the close-fitting wearing state;

[0050] Step 3: After completing step 2, the fabric feeding and receiving roller group 3 is used to drive the receiving end of the fabric feeding and receiving roller group 3 to reel in the fabric, while the feeding end of the fabric feeding and receiving roller group 3 feeds the fabric to be tested, so that the next position to be tested of the fabric to be tested reaches the guide drum 4;

[0051] Step 4: first use the fabric positioning unit 5 to position the fabric to be tested at both ends of the guide drum 4, then use the adjustment unit to drive the active structure to form a clearance fit with the fabric to be tested, simulating the loose wearing state of the fabric to be tested, and then use the impact wear detection unit 2 to simulate the impact wear detection process of the fabric to be tested in the loose wearing state;

[0052] Step 5: Repeat steps 3 and 4 to conduct continuous impact wear performance testing of the fabric to be tested.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
