Description

Technical Field

[0001] The utility model relates to the field of textile sample detection, in particular to a textile sample detection clamping device with a lifting device. Background Art

[0002] Textile sample testing process: Cut 3 samples, each with a size of at least 10cm×10cm, ensure that moisture cannot diffuse to the edge of the sample, the sample should be flat and wrinkle-free, and ensure that the edge yarn will not fall off during the test.

[0003] The samples were placed in standard atmospheric conditions to adjust the humidity balance.

[0004] First, weigh the original mass m0 of the sample using an electronic balance. Use a micropipette to suck in an appropriate amount of grade 3 water, drop 0.2mL±0.01ml of water on the center of the sample, and ensure that all the water is absorbed. Immediately weigh the mass m of the sample after the water is wetted using an electronic balance. Then quickly hang it in a standard atmosphere. The sample should hang vertically and naturally. Weigh the mass mi every (3±0.2)min.

[0005] The test is stopped when the remaining moisture mass drops below 10% of the total water mass or after cumulative drying for 60 minutes.

[0006] Textile samples need to be hung on a test frame during testing. The clips on the existing test frame cannot be adjusted. When the pattern width is wide, after the clips clamp the fabric, both ends of the fabric are suspended in the air, which will cause wrinkles and affect the accuracy of the test. It is inconvenient to remove the clips when they are damaged.

[0007] Therefore, it is necessary to provide a clamping device for textile sample testing with a lifting device to solve the above technical problems. Utility Model Content

[0008] In order to solve the above technical problems, the utility model provides a clamping device for textile sample testing with a lifting device.

[0009] The utility model provides a clamping device for textile sample detection with a lifting device, comprising a base, a mounting frame and a lifting device, wherein an electronic balance is fixed on the top of the base, a mounting frame is fixed on the detection end of the electronic balance, a rotating shaft is installed on the top of the mounting frame, two A-shaped spring clips are movably installed on the rotating shaft, the A-shaped spring clips can move in a horizontal direction relative to the rotating shaft, and can meet the detection requirements of textile samples of different widths, and a lifting device for lifting the textile sample from a vertical state to a horizontal state is installed on the base.

[0010] Preferably, the lifting device comprises a mounting seat and a lifting cylinder obliquely fixed on the mounting seat, a Z-shaped lifting frame is fixed to the output end of the lifting cylinder, and the Z-shaped lifting frame is provided with a horizontal portion cooperating with the textile sample.

[0011] Preferably, a avoidance hole for preventing water from getting in the center of the horizontal portion is provided.

[0012] Textile sample clamping process: The textile sample to be tested for drying rate is clamped by two A-shaped spring clips. Under the action of the textile sample's own gravity, the textile sample will be in a vertical state. Then the output end of the lifting cylinder drives the Z-shaped lifting frame to move upward, and the Z-shaped lifting frame contacts the textile sample until the horizontal part contacts the textile sample. At this time, the textile sample is in a horizontal state, and then it is convenient to drip water on the textile sample. The dripping part is opposite to the avoidance hole to prevent water from sticking to the Z-shaped lifting frame. After the dripping is completed, the output end of the lifting cylinder drives the Z-shaped lifting frame to move downward, so that the textile sample is in a vertical state again under the action of its own gravity, and the water evaporation rate is detected by an electronic balance.

[0013] Preferably, the mounting bracket comprises a bottom plate fixed to the detection end of the electronic balance, and columns are embedded and fixed at both ends of the bottom plate, and the top of the column is provided with an arc groove matched with the rotating shaft.

[0014] Preferably, a horizontal plate is fixed between the two upright posts to make the mounting frame more stable as a whole.

[0015] Preferably, mounting portions cooperating with the arc groove are provided at both ends of the rotating shaft, and the diameter of the mounting portions is smaller than the diameter of the middle portion of the rotating shaft to prevent the rotating shaft from being displaced in the horizontal direction.

[0016] Compared with the related art, the utility model provides the following beneficial effects:

[0017] The A-shaped spring clip can rotate or slide relative to the rotating shaft. By adjusting the horizontal position of the A-shaped spring clip relative to the rotating shaft, it can adapt to the clamping of samples of different widths, avoid wrinkles on the fabric, and ensure the accuracy of the detection.

[0018] When the A-shaped spring clip is damaged, the rotating shaft can be quickly removed from the arc groove. Since the A-shaped spring clip is sleeved on the rotating shaft, the A-shaped spring clip moves toward the installation portion, thereby removing the A-shaped spring clip from the end of the rotating shaft. A new A-shaped spring clip can be reinstalled from the end of the rotating shaft, and installation and disassembly are relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0029] Please refer to Figure 1-Figure 8 A clamping device for testing textile samples with a lifting device, the structure of which mainly includes a base 2, a mounting frame 3 and a lifting device 1. Specifically, the base 2 serves as the supporting foundation of the entire device, and an electronic balance 4 is fixedly installed on the top of the base 2. The electronic balance 4 is used to accurately measure the weight change of the textile sample to detect its water evaporation rate. The mounting frame 3 is fixed on the detection end (i.e., the weighing platform) of the electronic balance 4. The mounting frame 3, as an important component connecting the electronic balance 4 and the clamping mechanism, plays a role in stable support.

[0030] A rotating shaft 5 is installed at the top of the mounting frame 3. The rotating shaft 5 is the core rotating component of the clamping mechanism, and two A-shaped spring clips 6 are movably installed on it. The two A-shaped spring clips 6 are cleverly designed, and they can move freely in the horizontal direction relative to the rotating shaft 5 (there is a certain friction between the A-shaped spring clip 6 and the rotating shaft 5 when sliding relative to each other in the horizontal direction. When the Z-shaped lifting frame 9 lifts the textile sample, the A-shaped spring clip 6 will not move relative to the rotating shaft 5, avoiding wrinkles on the textile sample), so that the clamping position can be flexibly adjusted to meet the testing requirements of textile samples of different widths. In actual operation, the operator can easily clamp the textile sample to be tested by adjusting the spacing of the A-shaped spring clips 6.

[0031] A lifting device 1 is also installed on the base 2, and its main function is to lift the textile sample from a vertical state to a horizontal state for subsequent dripping treatment. Specifically, the lifting device 1 includes a mounting seat 7 and a lifting cylinder 8 obliquely fixed on the mounting seat 7. A Z-shaped lifting frame 9 is fixed to the output end of the lifting cylinder 8, and a horizontal portion 10 is provided on the Z-shaped lifting frame 9 to cooperate with the textile sample. When the output end of the lifting cylinder 8 moves upward, it will drive the Z-shaped lifting frame 9 to rise synchronously until the horizontal portion 10 contacts the textile sample, thereby lifting the textile sample from a vertical state to a horizontal state.

[0032] In order to prevent water from adhering to the Z-shaped support frame 9 during the dripping process and affecting the accuracy of the test result, an avoidance hole 11 is provided at the center of the horizontal portion 10. In this way, when dripping, the water droplets can directly pass through the avoidance hole 11 and drip onto the textile sample without adhering to the Z-shaped support frame 9.

[0033] The clamping process of the textile sample is as follows: First, the textile sample to be tested for drying rate is clamped by two A-shaped spring clips 6. Under the action of the textile sample's own gravity, it will naturally droop and be in a vertical state. Then, the lifting cylinder 8 is started, and its output end drives the Z-shaped lifting frame 9 to move upward. The end a of the Z-shaped lifting frame 9 first contacts the textile sample b near the middle position c (such as Figure 7 As shown in FIG. 1 ), the Z-shaped lifting frame 9 pushes the textile sample to deform. As the Z-shaped lifting frame 9 continues to move obliquely upward, the A-shaped spring clip 6 rotates relative to the rotating shaft 5, causing the upper part of the textile sample to gradually change from a vertical state to a horizontal state (as shown in FIG. 1 ). Figure 8As shown in the figure), until the textile sample is in a horizontal state (since the horizontal part 10 is in a horizontal state, the textile sample will be in a horizontal state after contacting the horizontal part 10), which is convenient for dripping treatment. The dripping part should be directly opposite the avoidance hole 11 to ensure that the water droplets can accurately drip on the textile sample and avoid water on the horizontal part 10. After the dripping is completed, the lifting cylinder 8 is started again, so that its output end drives the Z-shaped lifting frame 9 to move downward, so that the textile sample is in a vertical state again under the action of its own gravity. Finally, the water evaporation rate of the textile sample is detected by the electronic balance 4.

[0034] Regarding the specific structure of the mounting frame 3, it includes a bottom plate 12 fixed on the detection end (i.e., weighing platform) of the electronic balance 4. Columns 13 are embedded and fixed at both ends of the bottom plate 12, and the top of the column 13 is provided with an arc groove 14 that cooperates with the rotating shaft 5. The two ends of the rotating shaft 5 are provided with mounting parts 16 that cooperate with the arc groove 14, and the diameter of the mounting part 16 is smaller than the diameter of the middle part of the rotating shaft 5, so that the rotating shaft 5 can be prevented from being displaced in the horizontal direction, ensuring the stability of the clamping mechanism. In addition, a horizontal plate 15 is fixed between the two columns 13, which further enhances the overall stability of the mounting frame 3.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
