Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, and in particular to a portable color fastness tester. Background Technology

[0002] Color fastness refers to the resistance of the color of textiles to various effects during reprocessing and use. The fastness grade is determined based on the color change of the sample and the staining of the undyed lining fabric. When testing color fastness, a rubbing fastness tester is used. First, the sample is fixed, and then the test white cotton cloth is fixed on the test head. The test head slides back and forth to rub the sample. The color fastness is judged based on the degree of staining of the test white cotton cloth.

[0003] A patent document with publication number CN221745843U discloses a textile rubbing color fastness tester. After placing the sample fabric on the top surface of the test platform, the circumference of the sample fabric hangs down along the test platform. Then, the circumference of the sample fabric is clamped by clamping parts at corresponding positions on the counterweight frame. After clamping is completed and the counterweight frame hangs freely, the counterweight frame is located at the middle position of the test platform height. At this time, under the action of the weight of the counterweight frame, a tensile force is always applied to the circumference of the sample fabric. When the sample fabric is rubbed and stretched by the test head, it will be stretched outward by the constantly applied tensile force, so that the sample fabric always remains in a flat state, avoiding wrinkles and ensuring test accuracy.

[0004] Although the aforementioned textile rubbing color fastness tester can solve the corresponding technical problems, the clamping plate of its clamping component is fixed by clamping bolts and threaded holes. However, in order to maintain the clamping stability and flatness of the sample fabric, the clamping component has multiple clamping bolts around the counterweight frame. This means that each time the sample fabric is clamped, multiple clamping bolts on the clamping component need to be rotated in sequence, which makes the operation process more complicated. This not only increases the labor intensity of the staff, but also reduces the efficiency of color fastness testing.

[0005] Therefore, a portable color fastness tester is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a portable color fastness tester to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] A portable color fastness tester, comprising:

[0009] The color fastness tester body has a test platform fixedly connected to its operating table for supporting the sample fabric. The top of the test platform is provided with a pressing component for pressing the sample fabric. A counterweight frame for keeping the sample fabric flat is slidably fitted on the surface of the test platform. A clamping component for holding the sample fabric is provided on the counterweight frame. Two clamping components are provided on the surface of the counterweight frame.

[0010] The clamping assembly includes a pair of clamping plates, which are located on both sides of the counterweight frame. The surface of the counterweight frame is provided with an adjusting member for driving the two clamping plates to move synchronously towards or away from each other. The surface of the counterweight frame is also provided with a guide member that is arranged opposite to the adjusting member and is used to limit the clamping plates.

[0011] As a preferred technical solution, the two upper clamping plates are located on the front and rear sides of the counterweight frame, respectively, and the two lower clamping plates are located on the left and right sides of the counterweight frame, respectively.

[0012] As a preferred technical solution, a rubber pad is fixedly connected to the side of the clamping plate near the counterweight frame, and the length of the rubber pad is smaller than the length of the clamping plate.

[0013] As a preferred technical solution, the adjusting component includes a bidirectional screw, with both ends of the bidirectional screw threaded through to one side of the corresponding clamping plate. A first protrusion is rotatably connected to the surface of the bidirectional screw, and one side of the first protrusion is fixedly connected to the counterweight frame.

[0014] As a preferred technical solution, a knob is fixedly connected to one end of the bidirectional screw.

[0015] As a preferred technical solution, the guide includes a guide rod, the two ends of which slide through to one side of the corresponding clamping plate, and a second protrusion is fixedly sleeved on the surface of the guide rod, one side of which is fixedly connected to the counterweight frame.

[0016] As a preferred technical solution, the guide rod and the first protrusion have the same diameter, and both ends of the guide rod and the end of the bidirectional screw away from the knob are fixedly connected to a stop block, the diameter of which is larger than that of the guide rod.

[0017] As a preferred technical solution, the pressing component includes a cover plate that is fastened to the top of the counterweight frame, and a test groove is provided on the top of the cover plate.

[0018] As a preferred technical solution, an eccentric block is rotatably connected to the top of the operating table of the color fastness tester body, and the top of the eccentric block contacts the bottom of the counterweight frame.

[0019] This utility model has at least the following beneficial effects:

[0020] This application utilizes an adjusting mechanism to move two clamping plates on the same horizontal line synchronously towards or away from each other. This allows the clamping plates to gradually move closer to or away from the counterweight frame, enabling simultaneous clamping or releasing of both sides of the sample fabric placed on the counterweight frame. Two vertically arranged clamping components can clamp or release the entire circumference of the sample fabric. Therefore, only the two adjusting mechanisms need to be operated to move the two pairs of clamping plates synchronously, effectively reducing the number of clamping or releasing steps for the sample fabric. This reduces the workload of the workers, improves the testing efficiency of the sample fabric, and further enhances the portability of the color fastness tester. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3This utility model provides a portable color fastness tester, including a color fastness tester body 100, a test platform 200 for supporting the sample fabric, a pressing component 300 for pressing the sample fabric, a counterweight frame 400 for keeping the sample fabric flat, and a clamping component 500 for holding the sample fabric. The test platform 200 is fixedly connected to the operating table of the color fastness tester body 100, the pressing component 300 is disposed on the top of the test platform 200, and the counterweight frame 400 slides... The movable sleeve is mounted on the surface of the test bench 200. Two clamping components 500 are provided on the surface of the counterweight frame 400. The clamping components 500 include a pair of clamping plates 510, which are located on both sides of the counterweight frame 400. The surface of the counterweight frame 400 is provided with an adjusting member 520 for driving the two clamping plates 510 to move synchronously towards or away from each other. The surface of the counterweight frame 400 is also provided with a guide member 530 that is arranged opposite to the adjusting member 520 and is used to limit the clamping plates 510.

[0027] The two upper clamping plates 510 are located on the front and rear sides of the counterweight frame 400, respectively, and the two lower clamping plates 510 are located on the left and right sides of the counterweight frame 400, respectively. By using the two pairs of upper and lower clamping plates 510, the sample fabric can be clamped around its circumference, so as to apply tension to the sample fabric around its circumference in conjunction with the counterweight frame 400.

[0028] Among them, a rubber pad 511 is fixedly connected to the side of the clamping plate 510 near the counterweight frame 400. The length of the rubber pad 511 is smaller than the length of the clamping plate 510. The rubber pad 511 can increase the friction between the clamping plate 510 and the sample cloth, which helps to improve the stability of the clamping plate 510 in holding the sample cloth.

[0029] The adjusting component 520 includes a bidirectional screw 521 that is perpendicular to the corresponding clamping plate 510. Both ends of the bidirectional screw 521 are threaded through to one side of the corresponding clamping plate 510. The surface of the bidirectional screw 521 is rotatably connected to a first protrusion 522 via a bearing. One side of the first protrusion 522 is fixedly connected to the counterweight frame 400. By rotating the bidirectional screw 521, the two clamping plates 510 on it can be driven to move synchronously towards or away from each other under the action of the screw thread.

[0030] One end of the bidirectional screw 521 is fixedly connected to a knob 523, which allows the hand to easily rotate the bidirectional screw 521.

[0031] The guide member 530 includes a guide rod 531 arranged parallel to the corresponding bidirectional screw 521. The two ends of the guide rod 531 slide through to one side of the corresponding clamping plate 510. A second protrusion 532 is fixedly sleeved on the surface of the guide rod 531. One side of the second protrusion 532 is fixedly connected to the counterweight frame 400. When the clamping plate 510 moves, it can slide on the surface of the guide rod 531, which can guide the clamping plate 510, so that the clamping plate 510 can move stably along the axial direction of the bidirectional screw 521 and prevent the clamping plate 510 from rotating synchronously with the bidirectional screw 521.

[0032] The guide rod 531 has the same diameter as the first protrusion 522, and both ends of the guide rod 531 and the end of the bidirectional screw 521 away from the knob 523 are fixedly connected to a stop block 540. The diameter of the stop block 540 is larger than that of the guide rod 531. The stop block 540 can limit the movement of the clamping plate 510 and prevent the clamping plate 510 from moving excessively and slipping off the bidirectional screw 521 or the guide rod 531.

[0033] The pressing component 300 includes a cover plate 310 that is fastened to the top of the counterweight frame 400. The top of the cover plate 310 is provided with a test groove 320. The pressing component 300 can press the sample fabric on the counterweight frame 400, thereby further improving the stability of the sample fabric placed on the counterweight frame 400.

[0034] The color fastness tester body 100 has an eccentric block 600 rotatably connected to the top of its operating table via a rotating shaft. The top of the eccentric block 600 contacts the bottom of the counterweight frame 400. The eccentric block 600 provides auxiliary support to the counterweight frame 400, allowing it to be raised to a certain height. This facilitates bringing the clamping assembly 500 close to the sample fabric for clamping. After clamping the sample fabric, the eccentric block 600 is rotated to disengage from the counterweight frame 400, thus freeing the counterweight frame 400 from constraint. At this point, a tensile force can be applied to one circumference of the sample fabric through the counterweight frame 400.

[0035] It should be noted that the color fastness tester body 100 mentioned above is the composition of the power box, mounting platform, connecting arm and test head of a textile rubbing color fastness tester disclosed in the existing announcement number CN221745843U. It is prior art, so it will not be described in detail in this technical solution.

[0036] The working principle of this utility model is as follows: First, the sample cloth is placed on top of the counterweight frame 400, with the circumference of the sample cloth hanging down along the counterweight frame 400. Two sides of the sample cloth are inserted into the gap between the upper clamping plate 510 and the counterweight frame 400. The upper knob 523 is rotated, causing the corresponding bidirectional screw 521 to rotate. Under the action of the screw, the bidirectional screw 521 causes the two clamping plates 510 on its surface to move towards each other. The clamping plates 510 cause the corresponding rubber pads 511 to move until the upper rubber pad 511 is tightly against the surface of the sample cloth. Similarly, the other two sides of the sample cloth are inserted into the gap between the lower clamping plate 510 and the counterweight frame 400, and the lower knob 523 is rotated until the lower clamping plate 510 is tightly against the surface of the sample cloth. The rubber pad 511 below is pressed tightly against the surface of the sample fabric to complete the clamping operation of the sample fabric; then, the pressing component 300 is fastened to the top of the test platform 200, so that the cover plate 310 presses the sample fabric; then, the eccentric block 600 is moved so that the eccentric block 600 is disengaged from the bottom of the counterweight frame 400, the counterweight frame 400 is unrestrained, and under the gravity of the counterweight frame 400, a tensile force is applied to one circumference of the sample fabric, so that the sample fabric always remains flat; finally, the test white cotton cloth is assembled on the test head of the color fastness tester body 100, and the color fastness tester body 100 drives the test head to reciprocate and slide rub the sample fabric in the test groove 320, so that the color fastness of the sample fabric can be judged according to the dyeing condition of the test white cotton cloth.

[0037] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
