Description

Technical Field

[0001] The utility model relates to a staggered compact imaging system, belonging to the field of foreign fiber machines. Background Art

[0002] Foreign fibers are impurities in cotton. On bleached fabrics, they appear as red or blue spots, which have a great impact on the appearance of bleached fabrics. When removing foreign fibers, the foreign fibers are entangled with the internal silk threads of the cotton, and the cotton is difficult to flatten. A large amount of cotton has been entangled together, which increases the difficulty of separating the foreign fibers from the cotton, resulting in a large amount of cotton being removed when removing the foreign fibers, reducing the cotton yield.

[0003] The Chinese utility model patent with publication number CN201510729713.6 discloses a foreign fiber machine with the function of distinguishing and removing cashmere foreign fibers, wherein a controller is connected to a detection mechanism and a removal mechanism through a line; the driven end of the conveying mechanism is located below the outlet of the cashmere combing machine, and the active end is located above the transition plate and maintains a first set distance from the transition plate; the camera end face of the detection mechanism is parallel to the transition plate and maintains a second set distance from the transition plate; the solenoid valve and the air storage tank are located below the active end of the conveying mechanism and connected to the air inlet of the removal mechanism; the lighting mechanism is located above the transition plate, the lower end of the lamp box of the lighting mechanism maintains a third set distance from the transition plate, and the camera line of sight passes through the upper opening of the light source box; the removal mechanism outlet extends into the front end of the picking channel; the rear end of the picking channel is connected to the fan duct; the front end inlet of the suction channel is located below the removal mechanism, and the rear end duct is connected to the fan duct. The utility model can directly perform color setting comparison for sorting, does not require manual operation, has a simple structure, and has low processing and manufacturing costs. However, in the prior art, the distance between the detection area and the rejection area is fixed, and the time for the cotton flow to travel from the detection area to the rejection area varies with the speed of the cotton flow. If the rejection action is performed too early or too late, it is easy to fail to accurately remove foreign fibers in the cotton flow. In addition, in formal production and use, changes in cotton yield and cotton blending will also cause changes in the cotton flow speed, resulting in unstable foreign fiber removal effect.

[0004] Therefore, there is a need for a staggered compact imaging system to detect the flow velocity of foreign fibers. Utility Model Content

[0031] like Figure 1-7 As shown, a staggered compact imaging system in this embodiment includes two detection components 31, and the two detection components 31 are staggered along the cotton material conveying direction;

[0032] The detection assembly 31 includes a detection box 311, one side of the detection box 311 is open, a glass 312 is installed in the opening, a detection unit 313 and two lighting units 314 are arranged in the detection box 311, the two lighting units 314 are located on one side of the detection unit 313 close to the glass 312, and the two lighting units 314 are symmetrically arranged along the cotton material conveying direction, the lighting unit 314 is used to provide illumination, and the detection unit 313 is used to collect image information of foreign fibers;

[0033] The lighting unit 314 includes a first mounting frame 3141 and a lamp tube. The first mounting frame 3141 is fixedly disposed on the detection box 311, and the lamp tube is mounted on the first mounting frame 3141.

[0034] The detection unit 313 includes a second mounting frame 3131, a third mounting frame 3132, three cameras 3133 and three reflectors 3134. The second mounting frame 3131 and the third mounting frame 3132 are both fixedly mounted on the detection box 311. The reflectors 3134 are located on a side of the camera 3133 away from the glass 312. The three cameras 3133 are mounted side by side on the second mounting frame 3131. The three reflectors 3134 correspond to the three cameras 3133 one by one. The reflectors 3134 are mounted on the third mounting frame 3132.

[0035] The detection unit 313 further includes three cooling fans 3135, which correspond to the three cameras 3133 one by one, and the cooling fans 3135 are mounted on the second mounting frame 3131;

[0036] A light shielding plate 3136 is provided in the detection box 311, and the light shielding plate 3136 is located on a side of the camera 3133 close to the glass 312;

[0037] During operation, the side of the detection box 311 with an opening is fixedly set on the cotton material channel 2, and a backlight panel is set on the inner wall of the cotton material channel 2 away from the detection box 311. The cotton flows in the cotton material channel 2, and the lamp is lit to generate light. The light acts on the cotton and foreign fibers through the glass 312. At this time, the cotton and the foreign fibers show different colors. At the same time, the camera 3133 works, and the image information of the cotton and the foreign fibers is collected by the camera 3133 through the reflection of the reflector 3134. Since two detection components 31 are set, the foreign fibers in the cotton are collected twice at different positions. According to the distance between the two collection positions and the two collection times, the foreign fiber flow rate can be calculated, and according to the foreign fiber flow rate, the time for the subsequent foreign fiber removal action can be more accurately calculated, thereby improving the accuracy of foreign fiber removal, that is, improving the stability of the foreign fiber machine cleaning effect;

[0038] Moreover, the structure is more compact through staggered arrangement;

[0039] Of course, the color of the light generated by the lamp tube can be selected as purple, white or other colors according to actual work requirements. When two lamp tubes of different colors are used in the same detection box 311, the effect is better and it is easier to distinguish foreign fibers.

[0040] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
