Description

Technical Field

[0001] This utility model belongs to the field of fabric testing, and more specifically, it relates to a tooling for testing the bending performance of fabrics. Background Technology

[0002] Fabric bending performance testing is a test that evaluates the bending performance of a fabric by measuring its deformation at different bending radii. This test can effectively determine the stiffness of the fabric and verify the quality of the raw materials. Currently, traditional fabric bending performance testing usually uses the inclined plane method, where the sample is placed on a horizontal platform, and a sample pressure plate is used to push the sample along the long axis of the platform, causing the fabric to bend under its own weight. The bending length is then measured to evaluate the fabric's bending performance. However, since different fabric samples have uniform thickness, the sample pressure plate usually relies on its own weight to press the fabric sample on the horizontal platform. Therefore, the sample pressure plate cannot be adjusted according to the thickness of the fabric sample, and the fabric cannot make close contact with the sample pressure plate. This causes slippage during the movement of the fabric sample, resulting in errors in the bending length measurement and affecting the accuracy of the bending length measurement under the fabric's own weight, thus affecting the correct evaluation of the fabric's bending performance.

The device includes a threaded push rod 8, a platform base 10 welded to the front side of the housing 2, a long through groove near the top of the front side of the housing 2, a transparent window 5 bonded to the through groove of the housing 2, a through hole on the upper side of the push frame 7, a threaded adjusting rod 17 rotatably connected to the through hole of the push frame 7, an adjusting knob 12 welded to the top of the threaded adjusting rod 17, a guide post 14 welded to the upper side of the baffle 22, a threaded rotating rod 16 rotatably connected to the housing 2 at both the left and right ends, a knob 9 welded to the right side of the threaded rotating rod 16, and a rubber gasket 15 bonded to the lower side of the sample pressure plate 11.

[0023] In this embodiment, the rear side of the pusher frame 7 is provided with a protruding plate, and the center of the protruding plate is provided with a threaded through hole that runs from front to back. The outer side of the threaded push rod 8 is threadedly engaged with the threaded through hole of the protruding plate of the pusher frame 7. The protruding plate of the pusher frame 7 is inserted into the long through groove of the housing 2. The pusher motor 1 drives the pusher frame 7 to move left and right along the long through groove of the housing 2 through the threaded push rod 8, so that the sample pressure plate 11 drives the sample fabric placed on the platform seat 10 to move automatically. The upper side of the pusher frame 7 is provided with three sets of through holes from left to right, and the guide post 14 is inserted into the through hole at the leftmost end of the pusher frame 7.

[0024] In this embodiment, the front side of the sample pressure plate 11 is printed with scale marks to facilitate the measurement personnel to observe the bending length of the sample fabric. A threaded hole is provided at the center of the upper side of the sample pressure plate 11. Two sets of cylindrical protrusions are provided on the upper side of the sample pressure plate 11. The outer side of the threaded adjustment rod 17 is threadedly engaged with the threaded hole of the sample pressure plate 11. The two sets of protrusions on the upper side of the sample pressure plate 11 are respectively inserted into two sets of through holes near the right end of the push frame 7. During the rotation of the threaded adjustment rod 17, the sample pressure plate 11 is driven to move vertically up and down along the through holes of the push frame 7. The distance between the sample pressure plate 11 and the platform seat 10 is flexibly adjusted according to the thickness of the sample fabric to ensure that the rubber pad 15 on the lower side of the sample pressure plate 11 is in stable compression contact with the sample fabric, so that the sample pressure plate 11 pushes fabrics of different thicknesses to move stably horizontally along the platform seat 10 through the rubber pad 15.

[0025] In this embodiment, the outer side of the rotating rod 6 is provided with an external tooth structure, and an inclined plate 21 is welded to the outer side of the rotating rod 6. The front side of the inclined plate 21 is attached to the rear side of the transparent window 5. A mark is printed at the center of the front side of the inclined plate 21. The mark of the inclined plate 21 is aligned with the angle mark on the front side of the housing 2, so that the measuring personnel can observe the tilt angle of the inclined plate 21 through the transparent window 5 and the mark of the inclined plate 21.

[0026] In this embodiment, a rack 20 is welded to the center of the upper side of the slide table 18. The rack 20 is meshed with the external tooth structure of the rotating rod 6. A threaded through hole is provided at the center of the right side of the slide table 18. Both the left and right sides of the threaded through hole of the slide table 18 are provided with through holes that pass through to the left and right. The guide rod 19 is inserted into the through hole of the slide table 18. A threaded rotating rod 16 is meshed with the threaded through hole of the slide table 18. The threaded rotating rod 16 drives the rack 20 welded to the upper side of the slide table 18 to slide left or right along the guide rod 19. The rack 20 drives the inclined plate 21 welded to the rotating rod 6 to flip up and down through the external tooth structure of the rotating rod 6, and quickly changes the tilt angle of the inclined plate 21 according to different measurement standards.

[0027] In this embodiment, the baffle 22 has an L-shaped structure. A spring 13 is welded to the upper side of the L-shaped structure of the baffle 22, and a pusher frame 7 is welded to the top of the spring 13. During the horizontal movement of the pusher frame 7, the spring 13 pushes the lower side of the baffle 22 tightly against the upper side of the platform seat 10 through its own elastic force, so that the right side of the baffle 22 pushes the left end of the sample fabric synchronously during the movement, preventing the sample fabric from slipping and stopping sliding on the upper side of the platform seat 10, and ensuring that the sample fabric extends stably from the right end of the platform seat 10 along with the sample pressure plate 11.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In this invention, when performing fabric bending degree testing, the knob 9 is first manually turned. The knob 9 drives the slide 18, which is engaged with the outer side of the threaded rotating rod 16, to move left and right along the guide rod 19. Since the rack 20 on the upper side of the slide 18 is engaged with the outer tooth structure of the rotating rod 6, the rotating rod 6 drives the inclined plate 21, which is welded to the outer side, to rotate up and down, so that the mark of the inclined plate 21 aligns with the corresponding angle mark of the measuring standard on the machine housing 2. Then, the sample fabric is placed on the upper side of the platform seat 10, with the left end of the sample fabric adhering to the right side of the contact baffle 22. Then, the adjustment knob 12 is manually turned, which drives the threaded adjustment rod 17 to rotate. The threaded adjustment rod 17 drives the sample pressure plate, which is engaged with the outer side. 11 moves vertically downward along the through hole of the pusher 7, so that the rubber pad 15 bonded to the lower side of the sample pressure plate 11 adheres to the upper side of the sample fabric. Then, the controller 4 controls the pusher motor 1 to start through the wire. The pusher motor 1 drives the threaded pusher rod 8 to rotate. The threaded pusher rod 8 drives the pusher 7, which is rotated on the outer side, to move to the right along the long through groove of the housing 2. The pusher 7 drives the sample fabric squeezed by the baffle 22 and the sample pressure plate 11 to move synchronously to the right along the platform seat 10. The sample fabric extends out of the platform seat 10. The extended part of the sample fabric bends downward by its own weight until the right end of the sample fabric is aligned with the mark of the inclined plate 21. At this time, the length of the sample pressure plate 11 movement is observed to evaluate the degree of bending of the sample fabric.
