[0002] Shrinkage is an indicator of the change in fabric size after the fabric is soaked in water or washed and dried. It is one of the important wearing properties of the fabric. The main reason for shrinkage is that after the fabric is soaked in water, the fiber absorbs moisture and expands, making the diameter of the yarn thicker, the bending degree of the yarn in the fabric increases, and they are squeezed together. Although the fiber length increases, the expansion is very small, while the expansion in the diameter direction is very large, which causes the fabric to shrink. The fabric shrinkage tester is a machine widely used to measure the shrinkage and relaxation of various cotton, wool, linen, silk, chemical fiber fabrics, clothing or other textiles after washing.

[0023] See also Figures 1 to 4In the practical embodiment, a fabric shrinkage tester is provided. The fabric shrinkage tester will vibrate when conducting the test, and includes a bottom shell 1 and a tester body 2. The tester body 2 is a fabric shrinkage tester, which is a prior art, so it will not be explained in detail here. The four corners of the bottom of the bottom shell 1 are fixedly connected with a suction plate 3, which can fix the device to the ground by adsorption. A lifting mechanism is provided in the bottom shell 1, and the four lower ends of the lifting mechanism are fixedly connected with universal wheels 4 to facilitate the displacement of the device. The bottom of the bottom shell 1 is provided with four openings 5 ​​corresponding to the four universal wheels 4, and the upper surface of the bottom shell 1 is fixedly connected to the bottom of the tester body 2;

[0024] A mounting base 11 is fixedly connected to one side of the testing machine body 2, and two slots 12 are provided on one side of the mounting base 11. Insert blocks 13 are inserted in the two slots 12, and one end of the two insert blocks 13 is fixedly connected to a placement box 14 for holding detergent for fabric shrinkage test. A snap mechanism is provided in the mounting base 11, and both ends of the snap mechanism pass through the two slots 12. A slot 15 is provided on the upper side wall of the insert block 13, and one end of the snap mechanism is inserted in the slot 15. The placement box 14 can be used to store various detergents for fabric shrinkage test, which is easy to take, and the placement box 14 is firmly fixed, easy to disassemble, and easy to clean.

[0025] like Figure 2 and Figure 3 As shown: the buckle mechanism includes two sliding cavities 16 opened in the mounting seat 11, and sliders 17 are slidably connected in the two sliding cavities 16. The lower end of the slider 17 is fixedly connected with a card block 18, and the lower end of the card block 18 is inserted into the card slot 15. The upper end of the card block 18 is fixedly connected with a moving rod 19, and a compression spring 20 is fixedly connected between the slider 17 and the inner top wall of the sliding cavity 16. The upper ends of the two moving rods 19 penetrate the mounting seat 11 and are fixedly connected with a pull rod 21, which is firmly fixed. When it is necessary to remove the placement box 14, only the pull rod 21 needs to be pulled upward to drive the slider 17 fixed with the moving rod 19 to move in the sliding cavity 16, so that the card block 18 is separated from the card slot 15. At this time, the compression spring 20 is squeezed to generate elastic force. When the card block 18 is completely separated from the card slot 15, the insertion block 13 can be separated from the slot 12, so that the placement box 14 can be disassembled, and the disassembly is convenient for cleaning.

[0026] like Figure 4As shown: the lifting mechanism includes a stepper motor 6 fixed to the inner wall of the front end of the bottom shell 1, and the stepper motor 6 is connected to the control end of the test machine body 2 through a wire. The circuit involved is a prior art and can be fully implemented by a person skilled in the art. It is needless to say that the main shaft end of the stepper motor 6 is fixedly connected with a bidirectional screw rod 7, and two symmetrically arranged nut blocks 8 are threadedly connected to the bidirectional screw rod 7. The lower sides of the two nut blocks 8 are hingedly connected to two symmetrically arranged swing frames 9. The inner wall of the bottom shell 1 is slidably connected with a lifting plate 10, and the upper side of the lifting plate 10 is hingedly connected to the two swing frames 9. The universal wheel 4 is fixed to the lower side of the lifting plate 10. When it is necessary to make the test machine body 2 work more stably, the start The stepper motor 6 is driven to work, driving the bidirectional screw rod 7 to rotate. Since the bidirectional screw rod 7 is threadedly connected to the two nut blocks 8 respectively, at this time, the two nut blocks 8 are forced to move in opposite directions, thereby pulling the two swing frames 9 to swing, thereby driving the lifting plate 10 to move up in the bottom shell 1, and the universal wheel 4 can be moved up and retracted into the bottom shell 1, and the suction plate 3 is adsorbed and fixed to the ground, thereby improving the stability of the device during operation and preventing deviation. Secondly, if it is necessary to move the device, start the stepper motor 6 to reverse. Similarly, the universal wheel 4 can be pushed out of the bottom shell 1 to contact the ground until the suction plate 3 is lifted up and separated from the ground, which can facilitate the displacement of the device and is easy to operate.

[0027] like Figure 4 As shown: the lifting plate 10 is arranged in an I-shaped structure, and the four end side walls of the lifting plate 10 are slidably connected to the inner wall of the bottom shell 1, so that the displacement of the lifting plate 10 is more stable.

[0028] like Figure 4 As shown: the inner wall of the bottom shell 1 is fixedly connected to two vertically symmetrical positioning rods 23, and the two positioning rods 23 are both arranged to penetrate the lifting plate 10 to ensure that the lifting plate 10 moves straight up and down.

[0029] like Figure 2 As shown, the inner wall of the placement box 14 is fixedly connected with three partition plates 22 arranged at equal intervals, so as to facilitate the classification and storage of different washing reagents for fabric shrinkage test.

[0030] like Figure 4 As shown: the bottom wall of the bottom shell 1 is detachably connected to the ground suction plate 3 by means of threaded fixing, and the ground suction plate 3 can be detachably replaced.

[0031] Working principle: In this device, by adding a placement box 14 on one side of the testing machine body 2, it can be used to store various washing reagents for fabric shrinkage test, which is convenient to take. Secondly, when it is necessary to remove the placement box 14, just pull the pull rod 21 upward, which can drive the slider 17 fixed with the moving rod 19 to move in the slide cavity 16, so that the block 18 is separated from the card slot 15. At this time, the compression spring 20 is squeezed to generate elastic force. When the block 18 is completely separated from the card slot 15, the insert block 13 can be separated from the slot 12, so that the placement box 14 can be disassembled, which is convenient for cleaning;

[0032] When the test machine body 2 is used to conduct a shrinkage test on the fabric, first, the stepper motor 6 is started to drive the bidirectional screw rod 7 to rotate. Since the bidirectional screw rod 7 is threadedly connected to the two nut blocks 8 respectively, at this time, the two nut blocks 8 are forced to move in opposite directions, thereby pulling the two swing frames 9 to swing, and then driving the lifting plate 10 to move upward in the bottom shell 1, the universal wheel 4 can be moved upward and retracted into the bottom shell 1, and the suction plate 3 is adsorbed and fixed to the ground, thereby improving the stability of the device during operation and preventing deviation.
