[0002] Fabric skew refers to the phenomenon that weft yarn is inclined relative to warp yarn direction in fabric. The inclination usually occurs in the weaving process, if the tension of weft yarn is uneven, the weft guiding mechanism is improperly adjusted or the loom is unstable, the weft yarn cannot keep perpendicular to warp yarn when entering the shed, thus the weft skew is generated. The fabric with weft skew will affect the appearance quality, wearing performance, processing performance, strength and durability of fabric. Therefore, the fabric needs to be detected by fabric weft skew detector to ensure that the weft skew problem is found in time, which helps to take corresponding measures to adjust and correct in the production process, avoids the weft skew leading to the distortion of fabric pattern and design, ensures the appearance quality of fabric and improves the visual effect and aesthetic degree of product.

The bottom outer wall of fabric skew detection appearance 1 is equipped with jack 5, and jack 5 is the structure for being connected with keyboard and other components. Fabric skew detection appearance 1 adopts the principle of spectral imaging, mainly utilizes the response difference of fabric warp and weft to different wavelength light to accurately identify warp and weft direction and position, and then calculates the weft skew angle. The bottom outer wall of fabric skew detection appearance 1 is further fixedly connected with connecting power cord 4, and connecting power cord 4 is a cable assembly for electrically connecting the device with the power supply. A pair of fixed fabric support rods 21 are arranged on the detection platform 11, and a mounting groove 12 is formed in the bottom of the fabric skew detection appearance 1, and a cylinder 13 for driving the clamping mechanism switch is arranged in the mounting groove 12.

[0027] As Figures 2 to 3 The support rod 21 is provided with a supporting mechanism for placing the fabric flat on the upper surface of the detection platform 11, and the supporting mechanism comprises a U-shaped bracket 2 arranged in the mounting groove 12, both ends of the U-shaped bracket 2 are movably penetrated through the detection platform 11 and are fixedly connected with the support rod 21, the support rod 21 is provided with a fixed support block 3, the fixed support block 3 is provided with a second inclined surface 31, and the support rod 21 is provided with a first inclined surface 22 abutting against the second inclined surface 31, the first inclined surface 22 and the second inclined surface 31 abut against each other, so that the horizontal movement can be realized.

[0028] In addition, as Figure 3As shown, the jacking mechanism further comprises a limiting slide plate 23 fixedly connected to the first inclined abutting surface 22, which ensures that the fixed jacking block 3 can only move horizontally up and down on the abutting rod 21. The middle part of the fixed jacking block 3 is provided with a sliding expansion groove 32 for clamping the limiting slide plate 23, and the inside of the sliding expansion groove 32 is provided with a reset spring 33, which enables the fixed jacking block 3 to automatically return to the original position on the abutting rod 21 after movement, thereby ensuring repeated use. One end of the reset spring 33 is fixedly connected to the inner wall of the sliding expansion groove 32, and the other end of the reset spring 33 is fixedly connected to the limiting slide plate 23.

[0029] It is worth noting that, as Figures 2 to 3 shown, the end of the limiting slide plate 23 away from the first inclined abutting surface 22 is fixedly connected with a limiting clamping block 24 for clamping the fixed jacking block 3, which is used to prevent the fixed jacking block 3 from being pulled out of the limiting slide plate 23, thereby ensuring that the maximum stroke of the fixed jacking block 3 on the limiting slide plate 23 is to clamp the limiting clamping block 24.

[0030] Further, as Figures 1 to 3 shown, the bottom of the fixed jacking block 3 is fixedly connected with an anti-skid abutting pad 34, which is made of rubber and serves to increase the friction between the bottom of the fixed jacking block 3 and the fabric, thereby ensuring that the fabric will not slide and cause the fixed jacking block 3 to be unable to be stretched straight when the bottom of the fixed jacking block 3 is moved to stretch.

[0031] Still further, as Figure 1 shown, the bottom end of the fabric weft skew detector 1 is fixedly connected with a plurality of support seats 7, and the top outer wall of the fabric weft skew detector 1 is provided with a plurality of linearly arranged buttons 6 for controlling the switch of the fabric weft skew detector 1.

[0032] In this embodiment, when the fabric weft skew detection device is used, as Figure 1As shown, first, the fabric is placed flat on the upper surface of the detection table 11. At this time, the air cylinder 13 in the mounting groove 12 can be started, and after the air cylinder 13 is started, the piston rod drives the U-shaped support 2 to move downward, and the two ends of the U-shaped support 2 drive the corresponding abutting rods 21 to move, and the abutting rods 21 drive the fixed supporting blocks 3 to move through the limiting sliding plates 23. Until the anti-skid pads 34 at the bottom of the fixed supporting blocks 3 tightly abut against the fabric on the detection table 11, and then the first inclined abutting surface 22 on the abutting rod 21 abuts against the second inclined abutting surface 31 on the fixed supporting block 3, so that the pair of second inclined abutting surfaces 31 horizontally slide away from the air cylinder 13, and the anti-skid pads 34 at the bottom of the second inclined abutting surfaces 31 after moving drive the fabric to be spread flat. Finally, the size of the pair of second inclined abutting surfaces 31 spreaded can be controlled according to the characteristics of the fabric, so as to ensure that the fabric will not be excessively straightened or loosened after being spread, so that the fabric weft skew detection instrument 1 can accurately detect the fabric according to the characteristics of the fabric, which is fast and convenient.
