Description

Technical Field

[0001] The invention relates to the technical field of color fastness testing, in particular to a textile raw material dyeing performance testing device. Background Art

[0002] During the research and development or inspection process of textile fabrics, the dyeing performance needs to be tested to ensure that the fabric will not fade during use. There are many existing dyeing performance test methods, such as water immersion test, friction test, scrubbing test, etc. Among them, the friction test is to fix the friction standard white cotton cloth on the friction head, rub the dyed fabric according to regulations under a certain pressure, and evaluate the degree of staining of the standard white cloth under a standard light source.

[0003] In the prior art, a textile fabric color fastness detection device with publication number CN117309748A fixes the detection fabric through a detachable fixing unit, realizes rapid clamping of the fixing unit, and improves the fabric detection efficiency. At the same time, the power unit drives the staggered sliding of the friction head, so that the power unit and the friction head move more balanced, avoiding the vibration of the friction head and ensuring the detection accuracy of color fastness.

[0004] Although the test fabric can be quickly clamped, there are still some defects in the actual test process. Since the test device can only clamp the two ends of the test fabric, when testing the dyeing performance of some elastic fabrics, the tester needs to stretch the elastic fabric before clamping it. Otherwise, the friction head will move the elastic fabric together during the friction test, thereby affecting the test results. In addition, two people are required to cooperate when fixing the fabric to clamp the elastic fabric, which is not only time-consuming and labor-intensive, but also greatly reduces the detection efficiency of the device.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figure 1-7A textile raw material dyeing performance testing device shown in the figure comprises a test bench 1, a driving box 2 is fixedly connected to the top of the test bench 1, a friction mechanism 3 for rubbing the fabric is arranged on the front side of the driving box 2, the friction mechanism 3 is mainly composed of a motor, a test block and a reciprocating connecting rod mechanism, which is a mature mechanism in the prior art and will not be described in detail here, a placing plate 4 is fixedly connected to the top of the test bench 1, a fixing cavity 5 is provided at the bottom of the placing plate 4 and the top of the test bench 1, a pair of fixing plates 6 are fixedly connected to the top of the placing plate 4 and close to one side of the friction mechanism 3, a slide groove 7 is provided on the top of the placing plate 4 and is communicated with the fixing cavity 5, a U-shaped frame 8 is slidably connected to the inner side of the slide groove 7, a clamping block 9 is slidably connected between the inner side of the U-shaped frame 8 and the fixing plate 6, a moving groove 10 is provided on the inner side of the U-shaped frame 8 and the side wall of the fixing plate 6, a moving block 11 is fixedly connected to both sides of the clamping block 9 and is slidably connected to the inner side of the moving groove 10, an upper spring 12 is fixedly connected between the moving groove 10 and the moving block 11, and the setting of the upper spring 12 facilitates pushing the clamping block 9 to reset;

[0032] A threaded rod 13 is rotatably connected to the inside of the fixed cavity 5, and a sliding block 14 is threadedly connected to the outer wall of the threaded rod 13, and a right-angle block 15 is fixedly connected to the front side of the sliding block 14. The side walls of the clamping block 9 are fixedly connected to a bottom plate 16 and are arranged through the top of the placement plate 4. A telescopic plate 17 and a telescopic cylinder 18 are fixedly connected to the side close to the bottom plate 16, and the telescopic plate 17 is slidably connected to the inside of the telescopic cylinder 18. A pull block 19 is fixedly connected to the bottom of the telescopic cylinder 18, and an inclined groove 20 that fits the inclined surface of the right-angle block 15 is opened on the front side of the pull block 19;

[0033] A pair of top plates 21 are fixedly connected to the bottom of the U-shaped frame 8, a push plate 22 is fixedly connected to the side wall of the sliding block 14, and a gap is left between the push plate 22 and the top plate 21, a driving motor 23 is fixedly connected to the side wall of the test bench 1, and the output end of the driving motor 23 passes through the inner side of the fixed cavity 5 and is fixedly connected to the side wall of the threaded rod 13, and a plurality of lower springs 25 are fixedly connected between the inner side of the telescopic cylinder 18 and the side wall of the telescopic plate 17. Through the setting of the lower springs 25, it is convenient to pull the telescopic plate 17 and the U-shaped frame 8 to reset, and an extension rod 43 is fixedly connected to the side wall of the right-angle block 15;

[0034] When testing the dyeing performance on the elastic fabric, first fix the test white cloth on the test head on the friction mechanism 3, and then put the elastic fabric through the clamping block 9 and place it between the U-shaped frame 8 and the fixed plate 6, then control the drive motor 23 to start and drive the threaded rod 13 to rotate, thereby driving the threaded sliding block 14 to move, and at the same time drive the right-angle block 15 to insert into the inclined groove 20, and squeeze the inclined groove 20 through the inclined surface of the right-angle block 15. Since the pulling block 19 is fixed on the telescopic cylinder 18, and the telescopic cylinder 18 is fixed on the clamping block 9 on the fixed plate 6, it cannot slide left and right, so that the sliding of the right-angle block 15 gradually squeezes the pulling block 19 to slide downward, and at the same time drives the clamping block 9 to slide downward through the telescopic plate 17, the telescopic cylinder 18 and the bottom plate 16 to clamp and fix the two ends of the fabric, and at the same time drives the moving block 11 to slide downward inside the moving groove 10 to compress the upper spring 12;

[0035] Then the push plate 22 on the sliding block 14 moves to the side of the top plate 21, and then pushes the top plate 21 to drive the U-shaped frame 8 to slide in the slide groove 7, and at the same time drives the extension rod 43 to move to the inclined groove 20, maintaining the clamping effect of the clamping block 9 on the two ends of the fabric, and drives the telescopic plate 17 to slide on the inner side of the telescopic cylinder 18, and at the same time stretches the lower spring 25, so as to achieve the stretching treatment of the elastic fabric, which can be the elastic fabric stretched to avoid the elastic fabric from being driven to move when the test fabric pushes the friction. Finally, the sliding block 14 touches the travel switch 32, and then the travel switch 32 controls the driving motor 23 to be closed through the controller, and at the same time starts the friction mechanism 3 to drive the test fabric to move back and forth on the elastic fabric for testing, and then under a certain pressure, the dyed fabric is rubbed according to regulations, and then after the friction is completed, the test fabric is taken out, and the degree of staining of the standard white cloth is evaluated under the standard light source, so that the test of the dyeing performance of the elastic fabric can be completed, and then the driving motor 23 is controlled to reverse and repeat the above operation in the reverse direction, so that the clamping and fixation of the elastic fabric can be automatically released, and then the fabric can be taken out.

[0036] In order to improve the stability of the device during operation, a guide rod 24 is fixedly connected to the inner side of the fixed cavity 5 and passes through the inner wall of the sliding block 14. The sliding block 14 is slidably connected to the outer wall of the guide rod 24. Through the setting of the guide rod 24, it can play a guiding role in the process of the sliding block 14 moving when the threaded rod 13 rotates, avoiding the sliding block 14 from rotating with the threaded rod 13, thereby improving the stability of the device during operation.

[0037] In order to limit the sliding of the U-shaped frame 8, limiting grooves 26 are provided at both ends of the inner side of the slide groove 7, and limiting blocks 27 are fixedly connected to both sides of the U-shaped frame 8 and slidably connected to the inner side of the limiting grooves 26. Through the setting of the limiting grooves 26 and the limiting blocks 27, the sliding of the U-shaped frame 8 can be limited, thereby preventing the U-shaped frame 8 from falling off and improving the stability of the device during operation.

[0038] In order to improve the stability of the clamping fabric, a plurality of protrusions 28 are fixedly connected to the bottom of the clamping block 9, and a recessed groove 29 is provided on the inner side of the U-shaped frame 8 and the top of the placement plate 4 and at a position corresponding to the protrusion 28;

[0039] By setting the groove 29 and the protrusion 28, when the clamping block 9 clamps the two ends of the fabric, the fabric can be squeezed into the groove 29 through the protrusion 28, thereby increasing friction and improving the clamping force.

[0040] In order to improve the stability during the fabric testing process, an adjustment slot 30 is provided on the top of the test bench 1, and an adjustment plate 31 is fixedly connected to the U-shaped frame 8 next to the adjustment slot 30;

[0041] When the push plate 22 pushes the top plate 21 to move and stretch the elastic fabric, it will drive the adjustment plate 31 to slide in the adjustment groove 30, thereby ensuring that when the subsequent friction mechanism 3 rubs the fabric, the bottom of the fabric is always in a supported state to avoid affecting the normal detection of the test device.

[0042] In order to improve the degree of automation of the device, a travel switch 32 is slidably connected to the bottom of the fixed cavity 5 and the moving track of the sliding block 14 relative to the position, and the travel switch 32 is electrically connected to the drive motor 23 and the motor on the friction mechanism 3 through the controller. A bottom groove 33 is opened through the front side of the test bench 1, and a rectangular rod 34 is slidably connected to the inner side of the bottom groove 33, and the side wall of the rectangular rod 34 is fixedly connected to the setting of the travel switch 32;

[0043] By setting the travel switch 32, when the driving motor 23 drives the sliding block 14 to move and stretch the fabric, after the sliding block 14 touches the touch end of the travel switch 32, the signal is transmitted to the controller through the travel switch 32, and then the controller controls the driving motor 23 to turn off, and controls the motor of the friction mechanism 3 to start, so as to realize automatic testing of the device and improve the degree of automation of the device.

[0044] In order to be able to adjust the opening position according to the elasticity of different elastic fabrics, a rack 35 is fixedly connected to the side wall of the test bench 1 and located above the bottom groove 33, a rectangular frame 36 is slidably connected to the outer wall of the rectangular rod 34, a tooth block 37 meshing with the rack 35 is fixedly connected to the top of the rectangular frame 36, a screw 38 is fixedly connected to the front side of the rectangular rod 34, an extrusion ring 39 is threadedly connected to the outer wall of the screw 38, and the side wall of the rectangular frame 36 is in contact with the side wall of the extrusion ring 39, and a return spring 40 is fixedly connected between the side wall of the rectangular frame 36 and the outer wall of the rectangular rod 34;

[0045] When the elasticity of different fabrics at the root needs to adjust the expansion position, first rotate the extrusion ring 39 to move spirally outward on the outer wall of the screw 38, thereby gradually releasing the extrusion on the rectangular frame 36, and then the elastic force of the return spring 40 pushes the rectangular frame 36 to slide outward, so that the tooth block 37 slides out of the meshing position with the rack 35, thereby releasing the position restriction of the rectangular rod 34, and the rectangular rod 34 can be pushed to adjust the position of the control drive motor 23 to close. After the adjustment is completed, rotate the extrusion ring 39 in the opposite direction and move spirally inward, thereby squeezing the rectangular frame 36 and pushing the tooth block 37 to slide into the rack 35, so that the tooth block 37 and the rack 35 mesh with each other, and at the same time compress the return spring 40, thereby achieving the fixation of the position of the rectangular rod 34.

[0046] In order to be able to accurately adjust the position of the travel switch 32 according to the stretched position of different fabrics, a pointer 41 is fixedly connected to the top of the tooth block 37, and a scale plate 42 is fixedly connected to the top of the rack 35. When the sliding rectangular rod 34 adjusts the position of the travel switch 32, the position of the pointer 41 sliding on the scale plate 42 can be observed, and then the position of the fabric stretched after adjustment can be determined to improve the accuracy of the test.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
