Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roughness laser detection, in particular to a textile fabric roughness laser detection device. BACKGROUND

[0002] Fabric roughness laser detection is a non-contact detection technology that uses laser technology to analyze the roughness of fabric surfaces, such as fiber arrangement density, texture fluctuations, and fiber gap size. The core principle is to use a specific light source (such as laser or near-infrared light) to illuminate the fabric surface, analyze the reflection, scattering, or absorption characteristics of the light, and combine the differences in the light signals captured by the sensor to quantitatively evaluate the roughness of the fabric surface (such as overall flatness and fiber distribution uniformity), and finally convert it into parameters that can be used for quality judgment (such as whether there are defects and whether the texture consistency meets the standards).

[0003] In the existing technology, the roughness laser detection of textile fabric requires more precision than the roughness laser detection of ordinary fabric. However, the current laser roughness detection has a big problem when detecting the roughness of dark fabric.

Through the linkage of the compression roller 5 and the fourth connecting shaft 28, after the liquid coating in the liquid conveying hole 29, it can be applied on the textile cloth through the second liquid outlet groove 31.

[0038] The outer side surface of the first connecting shaft 11 is fixedly connected with a barrel-shaped shell 12, the outer side surface of the first connecting shaft 11 is provided with a connecting frame 17, and the first connecting shaft 11 and the barrel-shaped shell 12 are rotationally connected, so that the arc-shaped pressing plate 18 can rotate.

[0039] The barrel-shaped shell 12 and the connecting frame 17 are fixedly connected on one side surface, the barrel-shaped shell 12 is internally provided with a hollow groove 19, and the connecting frame 17 and the barrel-shaped shell 12 are matched, so that when the barrel-shaped shell 12 rotates, the arc-shaped pressing plate 18 also rotates.

[0040] The hollow groove 19 is provided with a telescopic rod 13, one end of the telescopic rod 13 is fixedly connected with one side surface of a bottom plate 14, and the telescopic rod 13 can be telescopic in the barrel-shaped shell 12 through the design of the hollow groove 19, so as to lift the bottom plate 14 and drive the spring 16 to lift.

[0041] The bottom plate 14 is fixedly connected with a spring 16 on one side surface, and the other end of the spring 16 is fixedly connected with one side surface of the arc-shaped pressing plate 18. When the spring 16 is lifted by the bottom plate 14, the arc-shaped pressing plate 18 is also lifted, so as to pretreat the surface of the textile cloth.

[0042] The second connecting shaft 15 is provided with five groups on the outer side surface of the barrel-shaped shell 12, the material of the reflective layer 22 is barium sulfate (BaSO4) coating sheet, the five groups of second connecting shaft 15 are better matched with the arc-shaped pressing plate 18 for flattening, and the material of the reflective layer can better realize uniform laser scattering.

[0043] Working principle: first, the textile cloth to be detected is passed through the lower roller 2, then through the upper roller 3 and the pressing roller 5, and finally through the heating roller 6 and the external winding device for connection, so that the textile cloth is laid flat under the action of tension, and when the textile cloth is laid flat, the detection device is started, and the external winding device is started at the same time, driving the textile cloth to move, and the detection device is started at this time.

[0044] First, the device injects ethanol into the inside of the infusion hole 29, because the opening of the first liquid outlet groove 30 on the fourth connecting shaft 28 is small, a small amount of ethanol will flow out, and then seep out along the second liquid outlet groove 31, because the pressing roller 5 is in contact with the surface of the textile cloth, the ethanol will be evenly applied to the surface of the textile cloth with the rotation of the pressing roller 5, and then the textile cloth moves, when the cloth with ethanol moves to the first connecting plate 7, the cylindrical laser emitter 9 on the sleeve shell 8 emits laser, which is uniformly projected on the surface of the textile cloth, the light is reflected in a wide-angle diffuse reflection (not directional reflection) manner at an angle of forty-five to one hundred and twenty degrees, forming a uniform illumination without shadow and low contrast, then the textile cloth reflects the laser, and the dark cloth absorbs the energy of the laser, resulting in a large decrease in the reflected laser energy of the cloth; most of the energy that is not absorbed is diffusely reflected due to the roughness of the cloth surface (fiber gap, texture fluctuation), reducing the laser receiving rate of the first laser sensor 10, the ethanol applied to the surface of the cloth as an organic solvent can quickly dissolve oil stains, adhering small impurities, and take them away with volatilization, making the cloth surface clean, ensuring that the laser only interacts with the cloth fiber itself, excluding reactions with impurities (such as surface dust, fiber debris, etc. interference), thereby improving the detection effect of the first laser sensor 10, when the first laser sensor 10 detects that the cloth is dark textile cloth.

[0045] Firstly, the first connecting shaft 11 drives the barrel-shaped shell 12 to rotate counterclockwise, and the telescopic rod 13 in the hollow groove 19 slowly extends to drive the bottom plate 14 to lift; when the bottom plate 14 is lifted, the spring 16 is lifted synchronously, the arc-shaped pressing plate 18 rotates around the second connecting shaft 15 as the center, the opening angle of the arc-shaped pressing plate 18 becomes larger, and after the angle of the arc-shaped pressing plate 18 becomes larger, the outer surface of the arc-shaped pressing plate 18 contacts the surface of the textile fabric, the arc-shaped pressing plate 18 flattens the fabric, the fiber arrangement is more regular, the wrinkles are unfolded, the bulkiness is reduced, the laser can act more uniformly on the fabric surface, the signal fluctuation caused by the irregular microstructure is reduced, the repeatability and consistency of detection are improved, this design can significantly improve the detection effect, the core function is to improve the flatness and stability of the fabric surface, reduce the interference factors when the laser interacts with the fabric, and the spring 16 rebounds according to the hardness and tension of the fabric to prevent excessive pressure on the fabric. When flattening, the reflecting member 27 reflects the scattered laser on the surface of the fabric into the first laser sensor 10, improving the receiving rate of the first laser sensor 10 to laser energy.

[0046] After flattening, if it is detected during pretreatment that the fabric is dark fabric, the first linear laser emitter 23 on the second connecting plate 25 is started (the emitter is a near-infrared linear lamp), the emitted light is projected onto the reflecting lens 21 on the third connecting shaft 20, the reflecting lens 21 is a diffuse reflecting sheet, and due to the wavelength characteristics and strong penetration of the near-infrared linear lamp, it is more suitable for detecting dark fabric. After reflection, the light enters the second laser sensor 26 to complete detection, but if the near-infrared linear lamp is directly used for direct emission, the light will produce strong reflection at the convex part of the texture and shadow at the concave part, resulting in large local light intensity difference. The diffuse reflecting sheet has the characteristics of diffuse reflection (the light is uniformly scattered in all directions after irradiation), which can convert the direct light of the near-infrared linear lamp into diffuse light with multiple angles and low intensity difference. When this diffuse light irradiates the fabric surface, it covers multiple angles such as the convex, concave and side surfaces of the texture, weakens the local light difference caused by the height difference of the texture, and makes the light distribution on the fabric surface more uniform. In this way, it can avoid the distortion of the detection signal (such as reflectivity and absorbance) caused by local over-brightness / over-darkness, and it is especially suitable for detecting the dyeing uniformity of the fabric, the fiber density and other parameters sensitive to light uniformity.

[0047] The reflective layer 22 clamped in the reflecting lens 21 is a barium sulfate (BaSO4) coating sheet, which plays a role in guaranteeing the stability of the diffuse reflection performance and the consistency of the optical path parameters, and ultimately improves the precision of the detection system. If the cloth is light-colored cloth during pre-detection, the cloth will not be flattened, and then the cloth is detected by the second linear laser emitter 24 (low color temperature linear lamp) on the second connecting plate 25. Due to the weak light absorbance of light-colored cloth, the existing technology can achieve high-precision detection. Finally, the cloth with roughness after detection is heated by the heating roller 6 on the base 1, ethanol evaporates, and the detection is completed.
