Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cashmere production, in particular to a device for quickly picking out black stray hairs in cashmere. Background Art
[0002] Cashmere is milky white in color and yellowish overall, but there are very few black stray hairs in it. In order to improve product quality, the cashmere needs to be sorted before production to pick out the black stray hairs. The existing method is that workers spread the cashmere into a very thin layer under light and then pick them out with the naked eye. Since the black stray hairs are thin, they are difficult to find and the picking efficiency is low. Utility Model Content
[0003] In order to solve the above technical deficiencies, the utility model provides a device for quickly picking out black stray hairs in cashmere, which can quickly pick out the black stray hairs in the cashmere.
[0004] The utility model discloses a device for quickly picking out black stray hairs in cashmere. The device comprises a frame, two ends of the frame are provided with conveying rollers, a conveyor belt is wound around the conveying roller, a motor for driving the conveyor roller to rotate is provided on the frame, a mounting frame is vertically upwardly provided on the rear side of the frame, a heating lamp irradiating toward the conveyor belt and a thermal imager for downward detection are sequentially provided above the conveyor belt along the conveying direction of the conveyor belt, the rear end of the heating lamp is fixed on the mounting frame, a slide seat is provided on the rear side of the thermal imager, a slide rail is horizontally provided on the mounting frame, and the slide seat is slidably arranged on the slide rail.
[0005] During use, workers lay a very thin layer of cashmere on the conveyor belt, and the conveyor belt transports the laid cashmere. When the cashmere is transported under the heating lamp, it is irradiated by the heating lamp. Since the milky white cashmere absorbs less light and the black stray hair absorbs more light, there will be a temperature difference between the two after being irradiated by the heating lamp. When passing under the thermal imager, the thermal imager will display the temperature difference between the black stray hair and the surrounding cashmere, so that the black stray hair can be quickly detected. When black stray hair is detected, the conveyor belt is controlled to stop conveying, the thermal imager is moved away, and the black stray hair in the cashmere can be taken out.
[0006] To facilitate workers in laying cashmere on the conveyor belt, comb teeth are evenly arranged on the outer surface of the conveyor belt. The height of the comb teeth is 0.5 mm. A scraper is set on the mounting bracket on the side of the heating lamp away from the thermal imager. The lower side of the scraper is in contact with the comb teeth. Through the comb teeth and scraper, a thin layer of cashmere can be laid on the conveyor belt, and the laying uniformity is relatively consistent. After the inspection is completed, the cashmere on the conveyor belt can be removed with a comb.
[0007] Furthermore, in order to increase the temperature difference between the black stray hair and the creamy white cashmere after being irradiated by the heating lamp, the light emitted by the heating lamp is yellow light. Since creamy white cashmere is yellowish and reflects yellow light more strongly, the temperature difference between the black stray hair and the creamy white cashmere will be greater after being irradiated by yellow light, making it easier to distinguish them on the thermal imager.
[0008] The device for quickly selecting black stray hairs in cashmere obtained by the utility model has the beneficial effect that the cashmere laid on the conveyor belt is irradiated by a heating lamp and then detected by a thermal imager. The different light absorption rates of the black stray hairs and the milky white cashmere make the temperatures after irradiation different, so that the black stray hairs can be quickly detected. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic structural diagram of Example 1 of the present utility model;
[0010] Figure 2 For the utility model embodiment 1 Figure 1 A partial enlarged view of . DETAILED DESCRIPTION
[0011] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0012] Example 1:
[0013] like Figure 1 、 2 As shown, the utility model discloses a device for quickly picking black stray hair in cashmere, comprising a frame 1, conveying rollers 3 are provided at both ends of the frame 1, a conveyor belt 4 is wound around the conveyor rollers 3, a motor 2 is provided on the frame 1 to drive the conveyor rollers 3 to rotate, a mounting frame 5 is vertically arranged on the rear side of the frame 1, a heating lamp 9 irradiating toward the conveyor belt 4 and a thermal imager 7 for downward detection are sequentially arranged above the conveyor belt 4 along the conveying direction of the conveyor belt 4, the rear end of the heating lamp 9 is fixed on the mounting frame 5, the light emitted by the heating lamp 9 is yellow light, a slide 8 is provided on the rear side of the thermal imager 7, a slide rail 6 is horizontally provided on the mounting frame 5, the slide 8 is slidably set on the slide rail 6, comb teeth 11 are evenly arranged on the outer surface of the conveyor belt 4, the height of the comb teeth 11 is 0.5 mm, a scraper 10 is provided on the mounting frame 5 on the side of the heating lamp 9 away from the thermal imager 7, and the lower side of the scraper 10 is in contact with the comb teeth 11.
[0014] During use, workers use the comb teeth 11 and the scraper 10 to lay a very thin layer of cashmere on the conveyor belt 4, and the conveyor belt 4 transports the laid cashmere. When the cashmere is transported under the heating lamp 9, it is irradiated by the heating lamp 9. Since the milky white cashmere is yellowish, it reflects the yellow light more strongly, and the black stray hair absorbs more light. Therefore, the temperature of the two will be different after being irradiated by the heating lamp 9. When passing under the thermal imager 7, the thermal imager 7 will display the temperature difference between the black stray hair and the surrounding cashmere, so that the black stray hair can be quickly detected. When black stray hair is detected, the conveyor belt 4 is controlled to stop conveying, the thermal imager 7 is moved away, and the black stray hair in the cashmere can be taken out.
