Description

Technical Field

[0001] The utility model relates to the field of clothing production, in particular to a friction tester used for fabric color fastness detection. Background Art

[0002] Existing textiles (such as bed sheets, carpets, curtains and clothing fabrics, etc.) need to be tested for color fastness by friction testing with a friction tester to prevent the above-mentioned textiles from fading after friction with other fabrics and sticking to other fabrics (i.e., fading test), especially some denim fabrics. However, there are some problems with the existing testing method when testing fabrics on the laying process, as follows: (1) Wrinkles are easily formed after laying. When the fabric moves back and forth under the counterweight state, if wrinkles appear within the range of motion, it is easy for the fabric to get stuck or become difficult to move, which in turn causes the load force on the drive motor end to be too large, causing damage, etc.; (2) Some existing elastic fabric tests During the test, due to its elastic effect, the fabric was laid flat during the laying process. However, due to the elasticity during the actual operation, the corresponding position was in a pulling state, resulting in jamming, edge warping and friction. The tested fabric showed local dyeing on one side, serious dyeing around the circle but no dyeing in the middle, etc., which could not truly simulate the actual situation; (3) The existing fabric laying is time-consuming and difficult to operate. The two sides of the fabric are passed through the gap between the clamp and the platform. Due to the small gap and large resistance, it is difficult to pass the fabric through and it is not easy to flatten it. More importantly, the height between the clamp and the platform cannot be adjusted, which makes it difficult to apply thick and thin fabrics and has a small scope of application.

[0003] In summary, the existing friction tester needs to be further improved and upgraded. Utility Model Content

[0015] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The technical solution of the utility model provides a friction tester for fabric color fastness testing, which has a simple structure, is easy to implement and has low cost, and solves the problem that the existing fabric to be tested is time-consuming and difficult to lay, and wrinkles are easily formed after laying, resulting in frequent high load on the drive motor end and uneven dyeing of the tested fabric; in the utility model, the first clamping member and the second clamping member are both movably connected to the support seat, wherein the first clamping member can be hinged on the support seat to flip and open the table top of the material discharge table, so that the fabric can be directly laid flat on the table top of the material discharge table without any resistance, which is simple to operate, can be applied to any thickness of fabric and has extremely high material discharge efficiency; in addition, a fabric adjusting member is provided between the first clamping member and the second clamping member, which drives the fabric to be tested to be horizontally tensioned along the length direction of the support seat by fixing the two ends and adjusting the middle end, so that the fabric to be tested can always be kept in a taut state, ensuring that the tested fabric can be evenly dyed after friction, and avoiding the load phenomenon at the drive motor end, and at the same time, it can more accurately simulate the actual situation of fabric friction, making the test result more accurate.

[0017] (2) In the present technical solution, the first clamping member and the second clamping member are respectively located above and below the support seat. Such a structural design can save space to a certain extent. In addition, in this method, by controlling the movable displacement of the first clamping member, the entire table top of the unloading table can be quickly opened, which is convenient for rapid loading and unloading, and the testing efficiency is higher and more convenient.

[0018] (3) In the present technical solution, the second clamping member is a small cylinder disposed under the support seat, which is automatically controlled by the cylinder and has certain reliability and stability, and can ensure that the fabric to be tested will not loosen or detach after being held, thereby ensuring the stability of the test process.

[0019] (4) In the present technical solution, the fabric adjusting member is arranged on the side of the support seat through the installation principle of the pulley, so that the fabric adjusting member, the first clamping member and the second clamping member form a triangular structure. The fabric to be tested will be directly tensioned on the fabric adjusting member after being constrained. At this time, it is only necessary to rotate the fabric adjusting member to pull the fabric to be tested to continue to be tensioned horizontally. The operation is simple and can quickly and effectively drive the fabric to be tested to be tensioned and deformed.

[0020] (5) In the present technical solution, the cross-section of the fabric adjusting member is in the shape of a "cam". When the fabric adjusting member is rotated to pull the fabric to be tested and deform it, the protruding part of the cam will support the fabric to be tested, causing the fabric to be tested to tilt upward away from the surface of the unloading table. During the tilting process, the fabric is pulled and gradually begins to be stretched and deformed. When the deformation is completed, the supporting effect of the cam structure fails, and the fabric to be tested is laid flat on the surface of the unloading table again. This structural design method can make the fabric to be tested in a non-contact state with the surface of the unloading table during the process of being pulled and stretched, thereby reducing a certain amount of friction resistance and making the deformation effect more uniform and not interfered with.

[0034] This embodiment provides a friction tester for fabric color fastness testing, which has a simple structure, is easy to implement and has low cost, and solves the problem that the existing fabric A to be tested is time-consuming and difficult to lay, and wrinkles are easy to appear after laying, resulting in frequent high loads on the drive motor end and uneven dyeing of the tested fabric. It mainly adopts the following structure: support seat 1, control box 2, transmission assembly 3, movable plate 4 and fabric adjustment member 5; wherein,

[0035] The support seat 1 is in the shape of a long plate as a whole; a material unloading platform 11 is provided at the left end of the support seat 1 for the material A to be tested to be laid flat, and a fixing component for restraining the material A to be tested is provided on the unloading platform 11, and the fixing component includes a first clamping member 121 and a second clamping member 122. Among them, the first clamping member 121 is a rod-shaped body with a total length greater than the width of the unloading platform 11, one side of which is movably hinged to the support seat 1, and the other side is movably clamped to the support seat 1, and it can be suspended above the unloading platform 11 and straddled and parallel to the unloading platform 11; the second clamping member 122 is a cylinder, which is arranged below the support seat 1. When the fabric A to be tested is laid flat on the surface of the unloading table 11, one side of the fabric A to be tested is located in the gap between the first clamping member 121 and the unloading table 11, and the other side is below the support seat 1 and in the gap between the second clamping member 122 and the support seat 1. The first clamping member 121 presses one end of the fabric A to be tested onto the unloading table 11 through a top-down pressing force, and the second clamping member 122 holds the other end of the fabric A to be tested on the lower surface of the support seat 1 through a bottom-up holding force, thereby constraining the fabric A to be tested on the unloading table 11.

[0036] In this embodiment, the first clamping member 121 and the support seat 1 are respectively provided with mutually adaptable clamping parts (the clamping part is a groove structure, which is inserted into the two grooves through an external clamping block, and the first clamping member 121 and the support seat 1 can be fixed as a whole), and the first clamping member 121 and the support seat 1 are connected by the clamping connection of the clamping part to open or close the connection between the first clamping member 121 and the support seat 1; the first clamping member 121 and the support seat 1 are respectively provided with mutually adaptable hinge parts (the connection of the traditional hinge shaft and the hinge hole) The two are hingedly connected through a hinge part, so that the first clamping member 121 can swing to the upper position or the outer position of the support seat 1. When the first clamping member 121 swings and displaces only the upper position of the support seat 1, that is, the first clamping member 121 is arranged across the discharge table 11 and is parallel to it. When the first clamping member 121 swings and displaces only the outer position of the support seat 1, that is, the first clamping member 121 can be erected beside the support seat 1, opening the entire surface of the discharge table 11, so as to facilitate the subsequent rapid loading and unloading of the fabric A to be tested.

[0037] The movable plate 4 is suspended above the right end of the support base 1 through a supporting assembly 13 and is installed and connected to the transmission assembly 3; a detection fabric (not shown) is installed on the movable plate 4. The detection fabric can be a white dry cloth or a wet cloth according to the test requirements, and is fixed on the left side of the movable plate 4.

[0038] In this embodiment, the supporting assembly 13 is arranged on the right side of the support plate, and includes a slider 131 and a base 132 arranged on the support seat 1. The base 132 is two side walls, and the two side walls have relatively arranged sliding grooves. The slider 131 is slidably arranged in the sliding groove and is slidably connected to the base 132, and the movable plate 4 is hinged on the slider 131 so that it can be flipped and swung on the slider 131; when the slider 131 slides on the base 132, the slider 131 can drive the movable plate 4 to move back and forth along the length direction of the support seat 1.

[0039] The transmission assembly 3 is a connecting rod mechanism, which includes a first transmission rod 31 and a second transmission rod 32 which are hinged to each other, wherein the first transmission rod 31 is rotatably connected to the control box 2, and the second transmission rod 32 is hingedly mounted on the slider 131. The control box 2 controls the rotation of the first transmission rod 31, and the second transmission rod 32 is linked to drive the slider 131 to slide on the base 132, so that the movable plate 4 moves back and forth along the length direction of the support seat 1 above. Therefore, by controlling the operation of the control box 2, the movable plate 4 can be driven to move back and forth along the length direction of the support seat 1, so that the detection fabric on the movable plate 4 and the fabric to be detected A on the unloading table 11 are frictionally matched.

[0040] The fabric adjusting member 5 is mainly used to flatten the fabric A to be tested and make it taut. Otherwise, if the two ends of the fabric A to be tested are simply constrained and fixed and the friction test is continued, the testing process will still have a series of disadvantages like the existing tester. In this embodiment, the fabric adjusting member 5 is arranged between the first clamping member 121 and the second clamping member 122. When the fabric A to be tested is laid flat, it also needs to be laid on the fabric adjusting member 5, so that the fabric A to be tested laid flat on the unloading table 11 can be driven by the fabric adjusting member 5 to be horizontally tensioned along the length direction, so that the fabric A to be tested is in a taut state.

[0041] In this embodiment, the fabric adjusting member 5 and the first clamping member 121 are both rod-shaped and parallel to each other; wherein, through the installation principle of the pulley, the fabric adjusting member 5 is arranged on the side of the support seat 1 (i.e., between the first clamping member 121 and the second clamping member 122), so that the fabric adjusting member 5, the first clamping member 121 and the second clamping member 122 form a triangular structure, and when the fabric A to be tested is laid flat, the fabric A to be tested can pass through the fabric adjusting member 5 and enter the bottom of the support seat 1. At this time, the first clamping member 121 and the second clamping member 122 apply a force to the two ends of the fabric A to be tested, so that the fabric A to be tested is pressed against and tensioned on the fabric adjusting member 5, and at this time, the fabric adjusting member 5 only needs to be rotated to pull the fabric A to be tested horizontally to make it form a tight state.

[0042] In this embodiment, the outer surface of the fabric adjusting member 5 is provided with a convex strip along the length direction, that is, the cross-section of the fabric adjusting member 5 is in the shape of a "cam"; by rotating the fabric adjusting member 5, the protruding portion of the cam on the fabric adjusting member 5 abuts against the fabric A to be tested. Since the fabric A to be tested is in a tensioned state on the fabric adjusting member 5 at this time, the protruding portion will pull the fabric A to be tested to rotate with it, and the fabric A to be tested will be horizontally tensioned and deformed. In other embodiments, a simpler structural method may also be adopted: for example, the fabric adjusting member 5 is arranged between the first clamping member 121 and the second clamping member 122, and a buckle is provided on the fabric adjusting member 5. When the fabric A to be tested is laid on the fabric adjusting member 5, the fabric A to be tested and the fabric adjusting member 5 are fixed as one body through the buckle structure. At this time, the pulling effect can also be achieved by simply rotating the fabric adjusting member 5. However, such a simple structural method has certain disadvantages: that is, during the process of pulling the fabric A to be tested, the fabric A to be tested and the surface of the discharge table 11 are always in contact with each other (the existing surfaces of the discharge table 11 are all anti-slip surfaces, that is, the surface has friction particles for anti-slip), resulting in the fabric A to be tested always being subject to resistance during deformation, which seriously affects its deformation and tightening effect.

[0043] In order to solve the problem that the fabric A to be tested is always in contact with the surface of the unloading table 11 during the pulling process, resulting in the deformation of the fabric A to be tested being hindered; in this embodiment, a convex strip is provided on the outer surface of the fabric adjusting member 5 along the length direction, and the convex strip not only has the function of pulling the fabric A to be tested to deform, but also has a second function:

[0044] When the fabric adjusting member 5 rotates, the protruding part of the cam will support the fabric A to be tested, so that the fabric A to be tested will be lifted up away from the surface of the unloading table 11, and will gradually begin to be tensioned and deformed during the lifting process. When the deformation is completed, the supporting effect of the cam structure will fail, and the fabric A to be tested will be laid flat on the surface of the unloading table 11 again. Such a structural design can ensure that the fabric A to be tested is in a non-contact state with the surface of the unloading table 11 during the process of being pulled for tension and deformation, thereby reducing a certain amount of frictional resistance and making the deformation effect more uniform and free from interference.

[0045] The working principle and use process of this utility model:

[0046] First, fix the test fabric on the left end of the movable plate 4. Before testing the color fastness of the test fabric A, refer to Figure 1 First, flip the movable plate 4 to a certain angle and fix it through a bracket as shown in the figure; second, flip the first clamping member 121 to a certain angle around the hinge axis, so that the first clamping member 121 is erected beside the support seat 1, so as to realize that the table surface of the material discharge table 11 is completely open; third, one side of the fabric A to be tested is laid flat on the table surface of the material discharge table 11, and the other side is passed through the fabric adjustment member 5 to enter the bottom of the support seat 1; see Figures 2 to 4 , fourth, flip the first clamping member 121 around the hinge axis at a certain angle, so that the first clamping member 121 is suspended above the support seat 1 and parallel to the material discharge table 11, and rotate the first clamping member 121 at the same time until the protrusion on the first clamping member 121 is against the fabric A to be tested, so that one side of the fabric A to be tested is pressed on the table surface of the material discharge table 11 and kept fixed; fifth, slightly pull the other side of the fabric A to be tested, so that the fabric A to be tested is pressed against the rod surface of the fabric adjustment member 5 for tensioning, and at the same time control the operation of the cylinder, so that the other side of the fabric A to be tested is also pressed against the lower surface of the support seat 1 through the cylinder, so that the fabric A to be tested is completely constrained; see Figure 5 Finally, the first transmission rod 31 is controlled to rotate through the control box 2, and the second transmission rod 32 is linked to drive the slider 131 to slide on the base 132, so that the movable plate 4 is moved back and forth along its length direction above the support seat 1, so that the detection fabric on the movable plate 4 and the fabric A to be tested on the unloading table 11 are frictionally matched.

[0047] Therefore, in the utility model, the fabric can be directly laid flat on the surface of the material discharging table 11 without any resistance. The operation is simple, it is applicable to fabrics of any thickness and the material discharging efficiency is extremely high; and the fabric A to be tested can always be kept in a taut state, ensuring that the fabric can be evenly dyed after friction, and avoiding load phenomenon at the driving motor end. At the same time, it can also more accurately simulate the actual situation of fabric friction, making the test result more accurate.

[0048] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
