Description

Technical Field

[0001] This utility model belongs to the field of fabric testing technology, and in particular relates to a fabric sample width calibration device. Background Technology

[0002] Fabric tensile testing is a physical testing method that measures the elongation and breaking characteristics of fabrics by applying tensile force. Fabric tensile testing has high requirements for the width of the fabric sample. GB / T3923.1-2013 requires the width of the fabric tensile sample to be accurate to 5cm±0.1cm. Excessive error will seriously affect the accuracy of the test.

[0003] Therefore, in order to ensure the dimensional accuracy of fabric samples, fabric samples are now all cut manually. First, a ruler is used to make a calibration line on the fabric sample, and the excess yarn outside the calibration line is removed. Due to measurement errors, the position of the calibration line cannot be guaranteed to be accurate. Moreover, the ruler needs to be used frequently during the removal process, which can easily generate cumulative errors and affect the dimensional accuracy of the fabric sample. In addition, the fabric sample is not fixed stably, which can easily lead to measurement deviation. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] A typical embodiment of this utility model is as follows: Figure 1As shown, a fabric sample width calibration device includes a base platform 1, which is a rectangular steel plate. In this embodiment, the base platform 1 is 200mm long, 80mm wide, and 10mm high. A horizontal bubble meter 2 is provided on the upper surface of the base platform 1 to ensure that the base platform 1 is placed horizontally during measurement and to reduce measurement errors.

[0023] A scale 3 is provided on both sides of the upper surface of the base platform 1. The scale 3 is marked along the width direction of the base platform 1. In this embodiment, the scale 3 is marked with 10~70mm. By setting the scale 3 on both sides of the base platform 1, the 5cm position of the fabric sample can be quickly found, which is convenient for calibrating the fabric sample.

[0024] On the upper surface of the base platform 1, there are symmetrical columns 4 at the set positions on both sides. In this embodiment, the two columns 4 are set directly opposite the 5cm position of the scale. A slide rail 5 is connected between the tops of the two columns 4. A marking pen is slidably connected on the slide rail 5 so that the marking pen can slide along the length of the slide rail 5, thereby using the marking pen to calibrate the fabric sample.

[0025] According to GB / T3923.1-2013, the width requirement for fabric tensile test specimens is 5cm ± 0.1cm. Since the width of the fabric specimen has a significant impact on the accuracy of the tensile test results, in order to ensure accurate cutting of the fabric specimen, a slide rail 5 is set above the fabric specimen at 5cm. A marking pen is slidably connected to the slide rail 5, so that the marking pen can be used to mark the fabric specimen at 5cm, so that the yarn of the fabric specimen can be removed.

[0026] A baffle 6 is provided on one side wall of the base platform 1. The baffle 6 is arranged parallel to the slide rail 5. The baffle 6 extends along the length of the base platform 1. The baffle 6 is perpendicular to the upper surface of the base platform 1, and the height of the baffle 6 is greater than the thickness of the base platform 1.

[0027] A magnetic fixing block 7 is placed on the base platform 1. The magnetic fixing block 7 is magnetic and can be attracted to the upper surface of the base platform 1. The magnetic fixing block 7 is cuboid and its width is less than 5cm to avoid interference with the marking pen.

[0028] When in use, first place the fabric sample on the upper surface of the base platform 1, with the end of the fabric sample abutting against the side wall of the baffle 6. Then place the magnetic fixing block 7 on the base platform 1, with the side wall of the magnetic fixing block 7 abutting against the baffle 6. Use the magnetic fixing block 7 to fix the fabric sample and prevent the fabric sample from moving.

[0029] The slide rail 5 includes two parallel tracks 51 spaced a predetermined distance apart. Both ends of the two tracks 51 are fixed to two columns 4. A slider 8 is positioned between the two tracks 51, and the slider 8 is slidably connected to the two tracks 51. Specifically, as shown... Figure 2As shown, grooves are provided on the opposite sidewalls of the two tracks 51. The grooves are opened along the length of the track 51. Protrusions are provided on the sidewalls of the slider 8. The protrusions are adapted to the grooves so that the protrusions can be placed in the grooves and can slide along the length of the grooves, thereby realizing the relative sliding between the slide rail 5 and the slider 8.

[0030] There are two sliders 8, namely a first slider 81 and a second slider 82. The first slider 81 has a mounting hole in the middle. A marker pen fixing clip 9 is fixed on the first slider 81. The marker pen fixing clip 9 includes a clamping ring 91, which is positioned opposite the mounting hole. An opening is provided on one side of the clamping ring 91. The clamping ring 91 extends outward from both sides of the opening to form an adjustment plate. An adjustment hole is provided on both adjustment plates. An adjustment bolt 92 passes through the two adjustment holes. One end of the adjustment bolt 92 is connected to an eccentric handle 93 through a pin. A pad is fitted on the adjustment bolt 92 and is positioned between the eccentric handle 93 and the adjustment plate.

[0031] It is known that only part of the bottom of the clamping ring 91 is fixedly connected to the first slider 81 to ensure that the clamping ring 91 can deform and clamp the marker pen.

[0032] When using it, first rotate the eccentric handle 93 counterclockwise to open the clamping ring 91. Then, with the pen tip facing down, pass it through the clamping ring 91 and the mounting hole in sequence. Adjust the distance between the pen tip and the upper surface of the base platform 1. Then, rotate the eccentric handle 93 clockwise to tighten the clamping ring 91 and clamp the pen.

[0033] By setting the marker pen fixing clip 9, the marker pen is fixed in place, preventing it from shaking during the marking process and affecting the accuracy of the marking.

[0034] An observation hole is provided in the middle of the second slider 82, and a magnifying glass 10 is provided above the second slider 82. The lens of the magnifying glass 10 is positioned directly opposite the observation hole, so that the edge yarn of the fabric can be observed through the magnifying glass 10, making it convenient to remove the edge yarn of the fabric.

[0035] Working principle

[0036] In use, first lay the fabric sample flat on the surface of the base platform and use the magnetic fixing block to fix the sample to prevent it from moving and affecting the calibration accuracy. Fix the marking pen to the first slider with the marking pen fixing clip, and adjust the distance between the marking pen and the fabric sample to ensure that the marking pen can leave a mark on the fabric sample during the movement. Slide the first slider along the length of the slide rail and use the marking pen to calibrate the sample width of 5cm to form a calibration line. Manually remove the excess yarn outside the calibration line until it is near the calibration line. At this time, the edge of the sample is under the magnifying glass. Observe the difference of several yarns between the edge of the sample and the marking line through the magnifying glass to confirm the number of yarns and remove them accurately to ensure that the width of the fabric sample is 5cm±0.1cm.

[0037] This invention features symmetrically arranged columns at a 5cm mark on the surface of a base platform, with a slide rail connected above the columns. A marker pen is slidably connected to the slide rail, allowing the marker pen to accurately mark the 5cm mark on the fabric sample. A magnifying glass is also slidably connected to the slide rail, enabling observation of the fabric edge and precise removal of the yarn at the fabric edge. This eliminates the need for repeated measurements and avoids the impact of inaccurate fabric sample calibration and immediate errors on the accuracy of the fabric tensile test structure.
