Description

Technical Field

[0001] This invention belongs to the field of scratch resistance testing technology, and more specifically, relates to a scratch resistance testing device for fabrics used in daily life. Background Technology

[0002] After fabric is produced, it needs to undergo a scratch resistance test to determine its scratch resistance. However, different fabrics have different scratch resistance requirements in different environments, but current testing methods mostly involve handheld scratch testing tools or using machines (such as the testing instrument at the following website: https: / / www.zhihu.com / zvideo / 1625877673145769984?utm_id=0) to replace manual testing. During the testing process, the fabric needs to be fixed in place beforehand, and it is impossible to fix or loosen the fabric synchronously according to the movement of the tool, which is inconvenient for handling the fabric and has limitations.

[0003] In view of the shortcomings of the existing technology, a fabric scratch resistance test device that can overcome the shortcomings of the existing technology is designed to facilitate the fixing and loading of materials, eliminate the need for manual pre-fixation, and simultaneously pull the sides of the fabric from multiple directions to improve the test accuracy, thus simulating the scratch resistance of everyday fabrics. Summary of the Invention

The sliding frame is slidably mounted on the rack. A switch electrically connected to the first cylinder is mounted on the sliding frame. A fixing member suitable for triggering the switch is slidably mounted on the sliding frame. One end of the fixing member protrudes downward to form a needle for insertion into the fabric on the test section. A connecting spring surrounding the fixing member is connected between the rear part of the fixing member and the sliding frame. The second cylinder is mounted on the upper right side of the sliding frame. A push-pull bracket that slides on the protruding end of the fixing member is connected to the piston rod of the second cylinder.

[0009] Preferably, it further includes a cylinder three, a smoothing brush, an elastic element, a guide rod, and a guiding mechanism. The cylinder three is mounted on the worktable. A smoothing brush suitable for smoothing the fabric on the test section is slidably mounted on the piston rod of the cylinder three. An elastic element, which is a spring, is connected between the smoothing brush and the piston rod of the cylinder three. The guide rod is connected to the upper part of the smoothing brush. The worktable is provided with a guiding mechanism for limiting the guide rod so that the smoothing brush only contacts the fabric once during reciprocating movement.

[0010] Preferably, the guiding mechanism includes a guide rail, a check plate, and a torsion spring. The guide rail is located on the upper rear side of the worktable. A check groove with its ends connected is opened on the upper front side of the guide rail. The check groove is vertically arranged, and the guide rod slides within the check groove. One end of the check groove is inclined and hinged to a check plate that contacts and cooperates with the guide rod. The check plate contacts and cooperates with the inclined end of the check groove.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. It should be understood that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] One embodiment: A fabric scratch resistance testing device simulating daily use, such as... Figures 1-3 As shown, the device includes a worktable 1, a cylinder 21, a connecting block 22, a sliding rod 23, a testing tool 01, a rack 41, a motor 43, a gear 44, a cam roller 45, and a right-angle reversing device 46. The upper side of the worktable 1 has a protruding testing section 10 for supporting the fabric and providing a support point during testing. The cylinder 21 is mounted on the upper left side of the worktable 1. The connecting block 22 is connected to the piston rod of the cylinder 21. The sliding rod 23 is slidably disposed on the upper part of the connecting block 22 and is used to support the testing tool 01. The rack 41 is slidably disposed on the upper part of the connecting block 22. Between the worktable 1 and the sliding rod 23, the motor 43 is installed on the upper left side of the worktable 1. The output shaft of the motor 43 is connected to a gear 44 that meshes with the toothed part 42 of the rack 41. Multiple convex rollers 45 are provided, and each of the multiple convex rollers 45 has serrations arranged on it to pull the fabric apart. The multiple convex rollers 45 are arranged in a square distribution around the test section 10. The multiple convex rollers 45 are synchronously driven by a right-angle commutator 46. One end of one of the convex rollers 45 is connected to the output shaft of the motor 43 to serve as the initial power source for driving the other convex rollers 45.

[0031] The operator can apply the corresponding technical solutions in this device to the scratch resistance test according to the specific situation. When it is necessary to use this device to assist in the fabric scratch resistance test, firstly, place the fabric to be tested on the test section 10, control the cylinder 21 to drive the connecting block 22 to move the sliding rod 23 to the right to adjust the position of the test tool 01 on the sliding rod 23, and then control the motor 43 to drive the gear 44 to rotate and mesh with the rack 41. The rack 41 will drive the test tool 01 to move down through the sliding rod 23, so that the test tool 01 contacts the fabric. At the same time, the motor 43 will drive the convex roller. Rotating at 45°, all the convex rollers 45 will rotate synchronously under the action of the right-angle reversing device 46. This allows the test tool 01 to automatically pull the fabric apart through the teeth on the convex rollers 45 when it comes into contact with the fabric, resulting in high synchronization. Then, the cylinder 21 can be controlled to drive the sliding rod 23 to move the test tool 01 back and forth for testing. Because the fabric is pulled apart, the test tool 01 can effectively contact the fabric, improving the accuracy of the test and preventing the fabric from being wrinkled, resulting in high stability. This allows the physical characteristics of the fabric to be tested through mechanical stress, thereby analyzing the fabric's scratch resistance.

[0032] Second embodiment: Based on the first embodiment, such as Figure 4 and Figure 5 As shown, it also includes a prismatic rod 31, a tool holder 35, a nut 32, a washer 33, and a compression spring 34. The prismatic rod 31 is slidably disposed at one end of the sliding rod 23 near the test section 10. The lower end of the prismatic rod 31 is provided with a tool holder 35 for supporting the test tool 01 in place of the sliding rod 23. The nut 32 is threadedly connected to the lower end of the prismatic rod 31. A washer 33 is placed on the upper side of the nut 32 and surrounds the prismatic rod 31. A compression spring 34 surrounds the prismatic rod 31 and connects the washer 33 and the sliding rod 23.

[0033] Tightening nut 32 causes washer 33 to move upward, pre-compressing spring 34. This adjusts the pressure applied outward by spring 34, allowing for convenient adjustment of the intensity when simulating natural pressure application, resulting in diverse usage methods. During testing, sliding rod 23 moves downward, driving blade holder 35 downward via prismatic rod 31, thus bringing test tool 01 into contact with the fabric. When test tool 01 contacts test section 10 through fabric, sliding rod 23 continues to move downward, compressing spring 34. Spring 34 adapts to deformation and applies pressure to prismatic rod 31, causing prismatic rod 31 to drive test blade downward via blade holder 35. As test blade reciprocates, prismatic rod 31 can slide upward on sliding rod 23 and apply downward pressure under the action of spring 34, simulating natural scratch resistance testing with good results.

[0034] like Figure 4 and Figure 5As shown, it also includes a buckle 36, a blade holder 35 rotatably mounted on a prismatic rod 31, and a plurality of blade slots on the blade holder 35 for supporting different types of testing tools 01. The testing tool 01 can be a short-bristled hard brush, a bladeless scraper, or a rod-shaped component, etc., to achieve the scratch resistance test of the fabric. The lower part of the prismatic rod 31 has a locking part 1 with the same number of blade slots and corresponding to each blade slot. The buckle 36 is slidably mounted on the prismatic rod 31, and the buckle 36 has a locking part 2 suitable for cooperating with the locking part 1; the locking part 1 is a locking hole, and the locking part 2 is a locking rod.

[0035] Different types of test tools 01 can be installed on the knife slot of the knife holder 35 by means of magnetic attraction or screw connection, so as to diversify the test and simulate the scratch resistance test of the fabric in different environments in daily life; move the buckle 36 forward to make the second snap-fit ​​part disengage from the first snap-fit ​​part, and then rotate the knife holder 35 to replace different test tools 01. After the replacement is completed, move the buckle 36 backward so that the second snap-fit ​​part cooperates with the first snap-fit ​​part to complete the fixation.

[0036] Three embodiments: Based on the two embodiments, such as Figure 3 and Figure 6 As shown, it also includes a sliding frame 51, a switch 54, a fixing member 52, a connecting spring 53, a second cylinder 56, and a push-pull bracket 55. The sliding frame 51 is slidably mounted on the rack 41. A switch 54 electrically connected to the first cylinder 21 is installed on the sliding frame 51. A fixing member 52 suitable for triggering the switch 54 is slidably mounted on the sliding frame 51. One end of the fixing member 52 protrudes downward to form a needle for insertion into the fabric on the test section 10. A connecting spring 53 surrounding the fixing member 52 is connected between the rear part of the fixing member 52 and the sliding frame 51. The second cylinder 56 is installed on the upper right side of the sliding frame 51. A push-pull bracket 55 that slides on the protruding end of the fixing member 52 is connected to the piston rod of the second cylinder 56.

[0037] The piston rod of the second control cylinder 56 extends to drive the push-pull frame 55 forward. When the push-pull frame 55 contacts the needle of the fixing member 52 during its forward movement, the fixing member 52 moves forward synchronously, and the connecting spring 53 is compressed. When the test cutter moves down, the rack 41 moves down, which drives the sliding frame 51 to move down, so that the needle on the fixing member 52 inserts into the fabric. Then the piston rod of the second control cylinder 56 retracts. At this time, the fabric is pulled open by the convex roller 45, so the fabric will pull the needle on the fixing member 52. When the fabric is torn during the test, the connecting spring 53 resets, and the fixing member 52 will move backward and reset under the action of the resetting connecting spring 53 and press the switch 54, so that the first cylinder 21 is automatically and synchronously closed to stop the test when the fabric is torn.

[0038] Four embodiments: Based on the three embodiments, such as Figure 7As shown, it also includes a cylinder 61, a smoothing brush 62, an elastic element, a guide rod 64, and a guiding mechanism. The cylinder 61 is mounted on the worktable 1. The smoothing brush 62, which is suitable for smoothing the fabric on the test section 10, is slidably mounted on the piston rod of the cylinder 61. An elastic element, which is a spring, is connected between the smoothing brush 62 and the piston rod of the cylinder 61. The guide rod 64 is connected to the upper part of the smoothing brush 62. The worktable 1 is provided with a guiding mechanism for limiting the guide rod 64 so that the smoothing brush 62 only contacts the fabric once during reciprocating movement.

[0039] like Figure 7 and Figure 8 As shown, the guiding mechanism includes a guide rail 63, a check plate 65, and a torsion spring. The guide rail 63 is located on the upper rear side of the worktable 1. A check groove 631 with its ends connected is opened on the upper front side of the guide rail 63. The check groove 631 is vertically arranged, and the guide rod 64 slides within the check groove 631. One end of the check groove 631 is inclined and hinged to a check plate 65 that contacts and cooperates with the guide rod 64. The check plate 65 contacts and cooperates with the inclined end of the check groove 631. The torsion spring is connected between the check plate 65 and the guide rail 63.

[0040] Before testing the fabric, hold one end of the fabric and then control cylinder 3 61 to drive the smoothing brush 62 to move to the left to smooth the fabric, avoiding wrinkles from affecting the test. There is no need to smooth it manually, which improves work efficiency. When controlling cylinder 3 61 to drive the smoothing brush 62 to move to the right to reset, the smoothing brush 62 will reset along the check groove 631, thus avoiding messing up the fabric during reset.

[0041] like Figure 7 As shown, it also includes a support base 71 and a rotating frame 72. The support base 71 is located on the side of the workbench 1 where the cylinder 61 is installed. The rotating frame 72 is rotatably mounted on the support base 71 and is in contact with the smoothing brush 62. The rotating frame 72 is suitable for pressing the fabric on the test section 10.

[0042] like Figure 7 As shown, it also includes a magnetic block 73. The material of the test section 10 is a magnetic material. There are two magnetic blocks 73, which are opposite each other. Both magnetic blocks 73 are connected to the end of the rotating frame 72 used to press the fabric. The magnetic blocks 73 are magnetically attracted to the test section 10.

[0043] When the smoothing brush 62 moves to the left, it pushes the rotating frame 72. The rotating frame 72 first presses the fabric, and then the smoothing brush 62 smooths the fabric. When the smoothing brush 62 moves to the right, it releases the rotating frame 72. The rotating frame 72 will rotate in the opposite direction to reset under the action of the torsion spring to release the fabric. When the rotating frame 72 rotates, it will drive the magnetic block 73 to rotate to magnetically hold the test part 10, thereby improving the stability of the fabric fixation. When the rotating frame 72 rotates in the opposite direction, it will drive the magnetic block 73 to rotate in the opposite direction to disengage from the test part 10.

[0044] Five embodiments: Based on the four embodiments, such as Figure 1 and Figure 9 As shown, it also includes a first protective cover 81, a second protective cover 82, a flexible telescopic cover 83, and a brush 84. The first protective cover 81 is connected to the side of the workbench 1 where the cylinder 21 is installed. The sliding rod 23 and the rack 41 both slide through the first protective cover 81. The second protective cover 82 is connected to the side of the workbench 1 where the cylinder 56 is installed. The rack 41 and the smoothing brush 62 both slide through the second protective cover 82. The flexible telescopic cover 83 is connected between the rack 41 and the second protective cover 82. The second protective cover 82 is provided with a brush 84 whose bristles are interwoven with those on the smoothing brush 62.

[0045] The first protective cover 81, the second protective cover 82 and the soft telescopic cover 83 prevent the lint on the fabric from adhering to the parts, thus providing a protective function. The brush 84, together with the smoothing brush 62, can also prevent lint from adhering, and at the same time, the brush 84 can also clean the lint on the smoothing brush 62.

[0046] like Figure 7 As shown, it also includes a mechanical counter 9, which is connected to the workbench 1, and the connecting block 22 is in contact with the output end of the mechanical counter 9.

[0047] Each reciprocating movement of the connecting block 22 pushes the output of the mechanical counter 9 once, thereby automatically recording the number of reciprocating movements of the test tool 01, enabling testing and comparison.

[0048] Obviously, the embodiments described above are only some embodiments of the present invention, and not all embodiments. They only express the preferred implementation of the present invention and are described in a relatively specific and detailed manner, but should not be construed as limiting the scope of the present invention.

[0049] It should be noted that, for those skilled in the art, various modifications, additions or subtractions, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
