Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for color fastness testing, and in particular to a pretreatment device for color fastness testing of textiles and garments. Background Technology

[0002] Color fastness testing of clothing is an important test for evaluating the ability of textiles to resist fading or staining during processing, use or washing. For example, color fastness to perspiration testing is specifically conducted by placing strips of fabric cut to a fixed size from the garment as samples, immersing the samples in simulated perspiration, and then evaluating color changes and staining after drying.

[0003] Before testing the color fastness to sweat, the sample needs to be soaked in simulated sweat. The conventional method is to let the sample soak naturally in the solution for more than 15 minutes, or to use manual hammering to quickly wet the sample. After the sample is wetted, the excess water needs to be squeezed out manually with a plastic card. The entire pretreatment operation is inefficient. Utility Model Content

[0004] In view of this, embodiments of the present invention provide a pretreatment device for color fastness testing of textiles and garments, which pretreatments samples before color fastness testing to improve sample wetting efficiency. An embodiment of the present invention provides a pretreatment device for color fastness testing of textiles and garments, comprising: a sample stage with a groove on its upper surface for placing the sample; a roller pressing component, the roller pressing component including a spring seat and a pressure roller, the pressure roller being rotatably disposed in the groove, the spring seat connecting to the pressure roller and pulling the pressure roller taut, so that the pressure roller is in contact with the bottom of the groove; and a driving mechanism connected to the spring seat to drive the spring seat to reciprocate along the length of the groove, thereby driving the pressure roller to roll within the groove.

[0005] Furthermore, the spring seat includes a base plate, a top plate, a spring, and a bending rod. The spring is disposed between the base plate and the top plate, and the bending rod is disposed on the upper surface of the top plate for connecting the pressure roller. The base plate and the top plate are connected by the spring, which can provide a restoring force to pull the top plate.

[0006] Furthermore, one end of the top plate is provided with an extension portion integrally formed therewith and extending outward, and the bending rod is an L-shaped rod. The extension portion allows the bending rod to extend upward from the side of the sample stage to the position above the groove.

[0007] Furthermore, a first drainage hole and a second drainage hole are provided on the inner wall of the groove, which extends through the outer wall of the sample stage.

[0008] Furthermore, the groove is provided with an arched protrusion, which is used to assist in guiding the discharge of the squeezed solution.

[0009] Furthermore, at least two telescopic rods are provided between the bottom plate and the top plate.

[0010] Furthermore, the sample stage has a through groove extending from front to back, the drive mechanism is located within the groove, and the spring seat is slidably accommodated within the groove.

[0011] Furthermore, the pressure roller is rotatably connected to the bending end of the bending rod via a bearing.

[0012] Furthermore, the driving mechanism includes a servo motor, a lead screw, and a slide table. The slide table is threadedly connected to the lead screw. The servo motor is disposed at one end of the sample stage. The lead screw is connected to the output end of the servo motor. A guide groove for accommodating the lead screw is provided on the bottom wall of the slide groove. The slide table is slidably connected to the guide groove.

[0013] Furthermore, a lifting seat is rotatably mounted at the end of the bending rod. The lifting seat can rotate along the bending rod and abut against the upper surface of the sample stage, so that the pressure roller is away from the groove.

[0014] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The pretreatment device for color fastness testing of textiles and garments of this utility model uses a servo motor to drive the lead screw to move the slide table and spring seat back and forth, and cooperates with the pressure roller to automatically roll the sample, which significantly improves the wetting and squeezing efficiency and reduces manual intervention; the combination design of the spring seat and the telescopic rod ensures that the pressure roller presses down stably and avoids deviation. At the same time, the addition of rubber stripes and bearing structure on the surface of the pressure roller can both fit the sample rolling and reduce sample shrinkage caused by friction, ensuring the quality of pretreatment; the coordinated design of the boss in the groove and the first and second drainage holes effectively guides the rapid discharge of the solution after squeezing, avoiding residues that affect the test results; the linkage structure of the lifting seat and the bending rod simplifies the sample placement steps and makes operation convenient. This utility model integrates automation and multifunctionality, can be adapted to a variety of color fastness testing standards, and significantly improves pretreatment efficiency.

[0024] In the description of this utility model, it should be noted that the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0025] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please refer to Figure 1-2The present invention provides a pretreatment device for color fastness testing of textiles and garments, including: a sample stage 100, a roller pressing component 200 and a driving mechanism 300; wherein the upper surface of the sample stage 100 is provided with a groove 11 for placing the sample, the groove 11 is a long rectangular groove, since the size of the sample participating in the color fastness test is specified, the size of the groove 11 can be adapted to accommodate a variety of samples.

[0027] The roller pressing component 200 includes a spring seat and a pressure roller 26. The spring seat is slidably mounted on the sample stage 100, and the pressure roller 26 is mounted on the spring seat. The pressure roller 26 is cylindrical and its length is adapted to the width of the groove 11 so that the coverage of the area inside the groove 11 by the pressure roller 26 during the rolling process meets the requirements. Rubber stripes can also be added to the surface of the pressure roller 26. On the one hand, the compressible deformation capability of the rubber stripes can be used to make the pressure roller 26 roll against the sample surface.

[0028] In the actual implementation process, the entire device needs to be immersed in the solution, so the sample cloth strip is not easy to slip in the groove 11 when it is wet.

[0029] Please see Figure 2 The sample stage 100 has a through groove 12, and the drive mechanism 300 is located in the groove 12. The spring seat is slidably accommodated in the groove 12. The spring seat includes a base plate 21, a top plate 22, a spring 24 and a bending rod 25. The spring 24 is located between the base plate 21 and the top plate 22. The bending rod 25 is located on the upper surface of the top plate 22 for connecting the pressure roller 26. The base plate 21 and the top plate 22 are connected by the spring 24.

[0030] This design allows the spring 24 to provide restoring force to change the position of the top plate 22, and the movement of the top plate 22 drives the movement of the bending rod 25 connected to it, further causing the pressure roller 26 on the bending rod 25 to press down onto the inner wall of the groove 11 to contact the sample.

[0031] It should be noted that at least two telescopic rods 23 are provided between the base plate 21 and the top plate 22. The telescopic rods 23 are common sliding combination rods of male and female rods, which are used to guide between the base plate 21 and the top plate 22 to ensure that the top plate 22 will not move and deviate from the base plate 21 when pulled by the restoring force of the spring 24.

[0032] The telescopic rods 23 can also be distributed in a rectangular pattern at the four corners of the base plate 21 and the top plate 22 to improve the relative stability of the base plate 21 and the top plate 22.

[0033] Please see Figure 4In this embodiment, since the spring seat is located inside the slide groove 12, in order to allow the bending rod 25 to extend out of the mounting roller 26, an extension 2201 is integrally extended from one end of the top plate 22. The bending rod 25 is an L-shaped rod, and the extension 2201 allows the bending rod 25 to extend upward from the side of the sample stage 100 to the position above the groove 11.

[0034] Viewed from one end of the sample stage 100, the bending rod 25 extends upward from the side of the sample stage 100 to the top of the sample stage 100, thereby enabling the pressure roller 26 to be positioned parallel to the groove 11.

[0035] Furthermore, a bearing 2601 is provided at the axis of the pressure roller 26. The bearing 2601 is rotatably connected to the bending end of the bending rod 25. The bearing 2601 can improve the rotational flexibility of the pressure roller 26 relative to the bending rod 25, so as to avoid the pressure roller 26 making hard contact with the sample and causing the sample to wrinkle.

[0036] Please see Figure 3 In this embodiment, the drive mechanism 300 includes a servo motor 31, a lead screw 32, and a slide 33. The servo motor 31 is disposed on one end of the sample stage 100. The slide 33 is threadedly connected to the lead screw 32. The lead screw 32 is connected to the output end of the servo motor 31. A guide groove 13 for accommodating the lead screw 32 is provided on the bottom wall of the slide groove 12. The slide 33 is slidably connected to the guide groove 13.

[0037] The servo motor 31 is externally wrapped with a waterproof cover to make it suitable for use when immersed in a solution. At the same time, the end of the servo motor 31 that extends into the guide groove 13 needs to be mechanically sealed to improve its service life.

[0038] It should be noted that the slide table 33 is a rectangular part with threaded holes through it on both sides and threaded to the lead screw 32. Both ends of the slide table 33 are attached to the inner wall of the guide groove 13, so the slide table 33 will not deviate. In order to better connect the spring seat, screws or buckle structures can be added to the surface of the slide table 33 to connect it to the base plate 21.

[0039] The servo motor 31 is controlled to rotate forward and backward by a program to drive the slide table 33 to slide back and forth. When the excess water needs to be squeezed out after the sample is wetted, the water can be squeezed out by repeating the rolling action of the pressure roller 26.

[0040] To facilitate the removal of the sample after the sample stage 100 is removed and the sample is rolled to drain water, a first drainage hole 15 and a second drainage hole 16 are provided through the inner wall of the groove 11 facing the outer wall of the sample stage 100. The first drainage hole 15 and the second drainage hole 16 are respectively opened on the opposite inner sidewalls of the groove 11.

[0041] The first drainage hole 15 is located on the long side of the groove 11 and can be any shape suitable for drainage. The second drainage hole 16 is located on the short side of the groove 11. The second drainage hole 16 is a rectangular hole and the lower edge of the second drainage hole 16 is flush with the bottom wall of the groove 11.

[0042] This design allows the squeezed solution to drain easily along the flush-height holes, and facilitates drainage at both ends of the main drainage area.

[0043] Furthermore, an arc-shaped protrusion 14 is provided in the groove 11. The protrusion 14 is used to assist in guiding the discharge of the squeezed solution. The solution that overflows from the sample under the pressure of the pressure roller 26 flows along the arc-shaped surface of the protrusion 14 toward the end of the sample stage 100.

[0044] Please see Figure 4 To facilitate the placement of the sample into the groove 11, a lifting seat 27 is rotatably mounted on the end of the bending rod 25. The lifting seat 27 extends integrally into a rectangle in the direction away from the axis of the bending rod 25.

[0045] With this design, before use, the lifting seat 27 can be rotated so that one rectangular end of the lifting seat 27 abuts against the upper surface of the sample stage 100. This extends the distance between the bending rod 25 and the upper surface of the sample stage 100, thus raising the pressure roller 26 outside the groove 11, making it easier to place the sample into the groove 11.

[0046] The working principle of the above embodiment is as follows: When the sample needs to be wetted, the lifting seat 27 at the end of the bending rod 25 is rotated to abut against the surface of the sample stage 100, so that the pressure roller 26 is supported. The sample is placed in along the length direction of the groove 11. Then the lifting seat 27 is rotated and pulled by the restoring force of the spring 24. The top plate 22 connected to the spring 24 drives the bending rod 25 and the pressure roller 26 to press down into the groove 11 to contact the sample. Then the device is placed in the water box containing the solution so that the device is completely submerged. The servo motor 31 is controlled so that the servo motor 31 periodically drives the lead screw 32 to rotate back and forth. The lead screw 32 is threaded relative to the slide table 33 under rotation, so that the slide table 33 periodically slides back and forth along the length direction of the guide groove 13. The bottom plate 21 connected to the slide table 33 can slide back and forth in the slide groove 12, so that the pressure roller 26 rolls back and forth in the groove 11, so that the sample is continuously rolled until it is completely wetted during the soaking process, thereby improving the wettability.

[0047] After the sample is completely wetted, the device is removed and the rolling action is repeated. At this time, the saturated solution in the sample is squeezed out into the groove 11 by the rolling action of the pressure roller 26, and discharged along the arc direction of the protrusion 14 in the groove 11 and along the first drainage hole 15 and the second drainage hole 16, thus completing the pretreatment of the sample.

[0048] In this document, the directional terms such as front, back, top, and bottom are defined according to the positions of the components in the accompanying drawings and the positions between the components, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary accordingly depending on different methods of use and placement. The use of these directional terms should not limit the scope of protection claimed by this utility model.

[0049] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
