Description

TECHNICAL FIELD

[0001] The utility model belongs to the appearance detection technical field of silk cake, specifically relates to a device for detecting the color of bright silk. BACKGROUND

[0002] Bright silk, also known as light silk or light surface silk, is a kind of high-gloss fiber obtained through special processing technology and formula treatment in synthetic fiber production. Compared with ordinary synthetic fiber, bright silk has a smoother and more flat surface, significantly enhancing the ability to reflect light, thus presenting a brighter and more dazzling gloss effect. Therefore, the color of bright silk is one of the important indicators for measuring its glossiness.

[0003] In the production process of bright silk, uneven dispersion of impurities or additives (such as TiO2 whitening agent) in polyester raw materials may cause unevenness of the fiber surface and internal structure, thus affecting the gloss effect; improper control of melt temperature may change the flowability and cooling and solidification characteristics of the polymer, leading to the formation of dark spots or dark rings inside the fiber; in addition, unreasonable design of spinneret shape or partial hole blockage may cause inconsistent fiber diameters, and uneven local stress during extrusion may further produce high-density areas, affecting the uniformity of gloss; insufficient stability of equipment operation may also cause quality problems during spinning, comprehensively leading to the generation of bright silk color defects (such as color silk). The existence of color silk not only directly affects the glossiness of bright silk, but also adversely affects the gloss of the subsequent woven fabric, seriously reducing the appearance quality and market competitiveness of the product. Therefore, the color detection of bright silk is crucial in its production process.

[0004] At present, the long filament industry generally uses external inspection machines to check the appearance quality of silk cakes. These existing external inspection machines are mainly designed for conventional silk silk cake products, and due to design limitations, they can usually only detect conventional appearance color problems of silk cakes, such as loose silk, sticking, poor forming, oil stains, etc., and cannot determine whether bright silk has color silk problems. In actual production process, in order to detect this specific problem, most rely on quality inspection personnel to use a handheld light source close to the surface of the silk cake to illuminate its interior, and observe whether there is color silk in the interior of the silk cake through the naked eye. This manual detection method is inefficient, time-consuming and labor-intensive, and has a negative impact on production efficiency.

[0005] Therefore, it is urgent to develop a device for detecting the color of bright silk to make up for the shortcomings of the prior art. UTILITY MODEL CONTENT

[0006] The utility model aims at solving the problems in the prior art and proposes a device for detecting the color of bright silk.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0008] A device for detecting the color of a bright filament includes a housing, a movable light source, a camera, and an image analysis system.

[0009] The mobile light source includes a high-intensity lamp and a telescopic mechanism. The telescopic mechanism extends vertically and its upper end is connected to the housing. The high-intensity lamp is located at the lower end of the telescopic mechanism, and a light shield is placed between the high-intensity lamp and the telescopic mechanism. The light intensity of the high-intensity lamp is 50-100 lumens. 50-100 lumens can illuminate the inside of the silk cake without causing overexposure due to excessive light intensity. The purpose of the light shield is to make the high-intensity lamp a "directional light source" to prevent the entire interior space of the housing from being illuminated by strong light, which would affect the shooting effect.

[0010] Camera a is located on the top wall of the enclosure;

[0011] Camera A sends the captured image of the silk cake to the image analysis system, which analyzes the image and outputs the detection results.

[0012] The telescopic mechanism extends downwards, bringing the strong light within 1cm of the silk cake. The inside of the silk cake will be illuminated by the strong light, and camera A can take a picture of the silk cake at this time. If dark spots or dark rings appear on the silk cake in the picture, it means that there are colored silk threads inside the silk cake, which is a defective product.

[0013] The device for detecting the color of a bright filament as described above also includes a switch a, which is connected to a high-intensity lamp.

[0014] The device for detecting the color of a bright filament, as described above, also includes camera b, camera c, camera d, and four fixed light sources;

[0015] Camera b is located on the bottom wall of the enclosure;

[0016] Camera c and two fixed light sources are located on the left side wall of the enclosure, and camera d and two other fixed light sources are located on the right side wall of the enclosure.

[0017] Cameras b, c, and d send the captured images of the silk cake to the image analysis system, which analyzes the images and outputs the detection results.

[0018] As described above, the device for detecting the color of a bright filament has fixed light sources symmetrically distributed vertically on the same side wall.

[0019] The device for detecting the color of a filament as described above also includes a switch b, which is connected to four fixed light sources.

[0020] The device for detecting the color of bright filament as described above also includes a feed guide device located below the housing;

[0021] The feeding guide device includes a conveyor belt and several pallets supported by it. The height of the pallets in the vertical direction is higher than the height of the bottom wall of the box. The pallets are arranged at intervals along the feeding direction, which is left and right. The feeding guide device is used to convey the yarn cake.

[0022] The device for detecting the color of bright yarn, as described above, also includes an alarm system; when the image analysis system outputs a non-compliant result, the alarm system issues an alarm signal. The image analysis system is typically linked to a sorting system; when the image analysis system outputs a non-compliant result, the sorting system removes the non-compliant yarn cake.

[0023] Beneficial effects:

[0024] This invention provides a device for detecting the color of glossy yarn, which can be used to detect whether colored yarns are present inside the glossy yarn cake, thereby improving the efficiency of colored yarn detection and saving manpower and resources. At the same time, this device can also be used to detect common color problems in the yarn cake, such as fuzz, dirt, and poor forming. Attached Figure Description
