Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing material detection, in particular to a structural color cotton fabric fastness testing device. Background Art

[0002] In the printing and dyeing industry, structural colors have the advantages of high brightness, high saturation, bright colors, sun resistance, and not easy to fade. For example, in the patent document with application number 201910446201.7, a method for preparing a polydopamine structural color film is disclosed, and a fastness test method is specifically disclosed. It is disclosed that the polydopamine structural color film fabric sample is placed face up on 3000 mesh sandpaper, and a bleached cotton fabric strip of the same material is placed on the structural color fabric. A 50g weight is used to provide pressure, and the cotton fabric strip is slowly pulled horizontally for 5cm. The color fastness of the structural color fabric is judged by the amount of black particles adhered to the bleached cotton fabric strip.

[0003] In the above technical scheme, the testing method is relatively simple. For example, for structural color fabrics of different thicknesses and different printing and dyeing times, the required sandpaper mass and weight of the weight are different. When the cotton fabric strip continues to move relative to the structural color fabric, the weight cannot move with the cotton fabric, so it is impossible to extend the time that the cotton fabric strip is in contact with the structural color fabric under a certain pressure. Summary of the invention

[0004] The purpose of the invention is to provide a structural color cotton fabric fastness testing device.

[0005] The technical problem solved by the present invention is to solve the problem in the prior art that when a cotton fabric strip moves relative to a structural color fabric, the weight cannot move with the cotton fabric strip, and the diversity of the test cannot be achieved.

[0006] The present invention can be implemented through the following technical scheme: a structural color cotton fabric fastness testing device includes a test base plate, on which a first support assembly and a second support assembly for clamping and limiting weights are arranged, the height of the first support assembly is higher than the height of the second support assembly, and the first support assembly and the second support assembly are movable relative to the test base plate.

[0007] A further technical improvement of the present invention is that the first support assembly includes a first support cross bar and a second support cross bar, the first support cross bar is fixedly installed at the output end of the bottom cylinder, and the second support cross bar is fixedly installed at the output end of the weight moving telescopic rod, and the bottom cylinder and the weight moving telescopic rod are fixedly installed on the test base plate.

[0008] A further technical improvement of the present invention is that a second position-limiting support cross bar is fixed on the first support cross bar, the second position-limiting support cross bar is slidably connected to the second support cross bar, a first position-limiting support cross bar is fixed on the second support cross bar, and the first position-limiting support cross bar is slidably connected to the first support cross bar.

[0009] A further technical improvement of the present invention is that a limiting groove is provided on the second limiting support cross bar, a sliding base is slidably arranged on the second limiting support cross bar, and a stabilizing plate for individually clamping the weights is fixed between adjacent sliding bases.

[0010] A further technical improvement of the present invention is that a limiting base is fixedly installed on the sliding base, a clamping column is slidably arranged on the limiting base, and a clamping protrusion and a limiting protrusion for clamping the second limiting support cross bar are respectively fixedly installed at both ends of the clamping column, and a spring is fixedly installed between the limiting protrusion and the limiting base.

[0011] A further technical improvement of the present invention is that the test base plate is made of a material that can be connected magnetically, and a plurality of fixed suction cups for limiting the positions of the sandpaper and the structural color fabric are magnetically adhered to the test base plate.

[0012] A further technical improvement of the present invention is that the size of the stabilizing plate is smaller than the size of the first supporting cross bar, and the stabilizing plate divides the first supporting cross bar into three equal parts.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present application realizes the clamping function of the weights by utilizing the first supporting assembly and the second supporting assembly, so the clamping of multiple weights can be realized by utilizing the joint action of the first supporting assembly and the second supporting assembly. Therefore, when the present application is in use, separate tests can be performed simultaneously according to sandpaper and weights of different masses, and multiple test results can be obtained at the same time. Moreover, the first supporting assembly and the second supporting assembly in the present application are movable relative to the test base plate, so the weights can be moved by the movement of the first supporting assembly and the second supporting assembly, so as to prolong the time that the fixed part of the cotton fabric strip is in contact with the structural color fabric with a certain pressure.

[0015] 2. The present application utilizes the first supporting cross bar and the second supporting cross bar to move toward or away from each other, so as to clamp the weights according to their sizes, thereby achieving precise adjustment of the distance between the first supporting cross bar and the second supporting cross bar. When clamping weights of different sizes at the same time, the present application utilizes a stabilizing plate that can be adjusted between the first supporting cross bar and the second supporting cross bar, that is, the stabilizing plate can be used to achieve further adjustment of weights of different sizes. The present application utilizes the clamping function of the first supporting cross bar and the second supporting cross bar to avoid the tilting problem of the weight due to its own inertia when the cotton fabric strip moves.

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-5 As shown, the structural color cotton fabric fastness testing device includes a test base plate 1, on which a fixed suction cup 7 for fixing sandpaper and structural color fabric is arranged, that is, in the present application, the test base plate 1 is made of a metal material that can be adsorbed, and the fixed suction cup 7 is provided with a plurality of groups, which can clamp a plurality of groups of sandpaper and structural color fabric of different sizes, so the scope of application in the present application is relatively large, and it is convenient to use the device for operation.

[0025] In order to achieve the pulling of the cotton fabric strip, that is, to move the cotton fabric strip on the structural color fabric, the present application has a top support frame 4 fixedly installed on the test base plate 1, and the top support frame 4 is n-shaped, and a connecting support seat 6 is fixed on the top support frame 4, and a connecting telescopic rod 5 is fixedly installed on the connecting support seat 6, and a clamping module 2 is fixed at the output end of the connecting telescopic rod 5. The clamping module 2 is used to clamp and fix the cotton fabric strip, and then under the action of the connecting telescopic rod 5, the cotton fabric strip is driven to move laterally, thereby achieving relative movement of the cotton fabric strip and the structural color fabric, so as to realize the color fastness detection of the structural color fabric.

[0026] In order to apply a certain pressure to the cotton fabric strip, a weight limiting mechanism 3 for limiting support and replacing the weight is provided on the top support frame 4.

[0027] Therefore, in the present application, the weight limiting mechanism 3 includes a weight moving telescopic rod 32, which is fixedly mounted on the top supporting frame 4, and a pushing base 33 is installed at the end of the weight moving telescopic rod 32, wherein the pushing base 33 is provided with a first supporting assembly 34 and a second supporting assembly 35 for clamping and supporting the weight, wherein the supporting heights of the first supporting assembly 34 and the second supporting assembly 35 are different, that is, the weight is clamped in multiple layers to ensure the stability of the weight movement, or to ensure that when the cotton fabric strip moves, the weight will not be likely to tip over due to inertia, and the distance between the first supporting assembly 34 and the second supporting assembly 35 is fixed, further ensuring the stability of the weight when clamping.

[0028] In the present application, the first support assembly 34 and the second support assembly 35 have the same structure, and the first support assembly 34 is taken as an example for description.

[0029] Therefore, the first support assembly 34 includes a first support cross bar 342 and a second support cross bar 344, wherein the distance between the first support cross bar 342 and the second support cross bar 344 is adjustable, and the first support cross bar 342 and the second support cross bar 344 are used to place the weight, that is, the weight is placed between the first support cross bar 342 and the second support cross bar 344, and the second support cross bar 344 can be driven to move by moving the telescopic rod 32 with the weight, so the output end of the telescopic rod 32 for moving the weight is fixedly installed on the second support cross bar by pushing the base 33. Rod 344, and the second support cross bar 344 is slidably connected to the first support cross bar 342, so when it is necessary to drive the weight to clamp or move, it is necessary to use the weight to move the telescopic rod 32 to start the second support cross bar 344 to move in the direction of the first support cross bar 342, so that the weight can be driven to move in the moving direction of the cotton fabric strip, so that the time for the weight to act on a fixed position on the cotton fabric strip can be controlled, thereby ensuring the diversity of the test process of the color fastness of the structural color fabric and the accuracy of the test results.

[0030] In order to realize the relative sliding of the first support cross bar 344 and the second support cross bar 342, a second limit support cross bar 345 is fixed on the first support cross bar 342, and a first limit support cross bar 343 is fixed on the second support cross bar 344, wherein the first limit support cross bar 343 and the first support cross bar 342 are slidingly connected, the second limit support cross bar 345 and the second support cross bar 344 are slidingly connected, and the first support cross bar 342 is fixedly installed at the output end of the bottom cylinder 341, and the bottom cylinder 341 is fixedly installed on the top support frame 4. Therefore, when in use, the distance between the first support cross bar 342 and the second support cross bar 344 is controlled through the joint action of the bottom cylinder 341 and the weight moving telescopic rod 32, so as to facilitate the clamping and fixing of multiple weights at the same time, and to be able to perform sliding tests on multiple groups of cotton fabric strips on the structural color fabric at the same time. In addition, the present application utilizes the existence of the bottom cylinder 341, so that the first support cross bar 342 can be fixed according to the bottom cylinder 341. When the cotton fabric strip moves, the first support cross bar 342 and the second support cross bar 344 are respectively used to limit the position of the weight and to correct the inertial tilt of the weight when the cotton fabric strip moves, so as to ensure that the weight is placed more stably on the cotton fabric strip.

[0031] Since the first support cross bar 342 and the second support cross bar 344 in the present application are relatively large in size, multiple sets of weights can be set between the first support cross bar 342 and the second support cross bar 344. However, the tests performed with different weights are also different, and the volumes of the weights are also different. The clamping stability of the weights by the first support cross bar 342 and the second support cross bar 344 cannot be guaranteed. Therefore, the present application provides an adjustable clamping assembly between two adjacent second limit support cross bars 345, and weights of another size can be stably clamped between the adjustable clamping assemblies.

[0032] Specifically, the adjustable clamping assembly includes a stabilizing plate 3413, a limiting groove 3410 is provided on the second limiting support cross bar 345, a sliding base 349 is slidingly arranged inside the limiting groove 3410, and adjacent sliding bases 349 are fixedly installed on the stabilizing plate 3413, that is, when in use, the stabilizing plate 3413 is used to slide inside the limiting groove 3410 to adjust the position of the stabilizing plate 3413. Therefore, in the present application, two groups of stabilizing plates 3413 can be provided, and the weights are placed between the two stabilizing plates 3413, and the weights are clamped by the two stabilizing plates 3413. Then, when the first support cross bar 342 moves, the weights are driven to adjust their position. The size of the stabilizing plate 3413 is smaller than the size of the first support cross bar 342, and the stabilizing plate 3413 divides the first support cross bar 342 into three equal parts.

[0033] In order to limit the position of the stabilizing plate 3413, a limiting base 346 is fixedly installed on the sliding base 349, and a clamping column 3411 is slidably arranged on the limiting base 346, wherein the two ends of the clamping column 3411 are respectively fixedly installed with a clamping protrusion 3412 for limiting connection with the second limiting support cross bar 345 and a limiting protrusion 348 for realizing the limiting function, and a spring 347 is fixedly installed between the limiting protrusion 348 and the limiting base 346. When in use, by applying pressure laterally on the limiting protrusion 348, the spring 347 is squeezed. At this time, the clamping protrusion 3412 is away from the second limiting support cross bar 345, and the sliding base 349 can slide inside the limiting groove 3410, thereby adjusting the position between the stabilizing plates 3413. After the adjustment is completed, the pressure applied to the limiting protrusion 348 is released, so that under the rebound action of the spring 347, the clamping protrusion 3412 is clamped on the second limiting support cross bar 345, thereby fixing the position of the stabilizing plate 3413.

[0034] When the present invention is used, firstly, the required sandpaper and structural color fabric are stacked and placed respectively through the fixed suction cup 7, so as to realize the laying of the base layer, and in this process, sandpaper and structural color fabric of different sizes and numbers can be laid, so as to realize the measurement of multiple measurement programs at the same time, and then multiple cotton fabric strips are placed on the test base plate 1, and the cotton fabric strips are clamped by the clamping module 2, and then the cotton fabric strips are moved and guided by the function of the connecting telescopic rod 5, and in this application, it is necessary to determine whether the weight and the cotton fabric strip need to continue to move at the same time. If necessary, the coordinated movement of the weight and the cotton fabric strip needs to be realized by the cooperation function of the weight moving telescopic rod 32 and the connecting telescopic rod 5; and when the weight and the cotton fabric strip do not need to move at the same time, the weight moving telescopic rod 32 stops working, and at this time, the movement of the cotton fabric strip can be controlled by only starting the connecting telescopic rod 5;

[0035] In the above technical solution, when it is necessary to clamp weights of different sizes, pressure is applied laterally to the limiting protrusion 348 so that the spring 347 is squeezed. At this time, the clamping protrusion 3412 is away from the second limiting support cross bar 345, so that the sliding base 349 can slide inside the limiting groove 3410, thereby adjusting the position between the stabilizing plates 3413 so that the distance between the stabilizing plates 3413 can be suitable for weights of corresponding sizes. After the adjustment is completed, the pressure applied to the limiting protrusion 348 is released, so that under the rebound action of the spring 347, the clamping protrusion 3412 is clamped on the second limiting support cross bar 345, thereby fixing the position of the stabilizing plate 3413.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
