Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a fluorescent whitening agent detection device. Background Art

[0002] Fluorescent brighteners are widely used in papermaking, textiles, plastics, detergents and other fields. They can absorb invisible ultraviolet light and convert it into blue or purple light with longer wavelengths, which complements the yellow light of the object itself, making the object look whiter, brighter and more colorful.

[0003] Most fluorescent whitening agent detection devices achieve the effects of detection and shooting by setting up a detection box with detection modules, cameras and other components inside. The images captured by the camera will be transmitted to the data analysis system.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-Figure 14As shown, a fluorescent whitening agent detection device comprises a detection box 1 with a box door 2, the box door 2 is hingedly connected to the detection box 1 by a hinge, a lock matched with the detection box 1 is installed on the box door 2, and a handle is installed on the outer side of the box door 2 to facilitate the staff to open or close the box door 2, a sliding plate 3 is slidably provided inside the detection box 1, and two detachable sample storage barrels 4 are symmetrically provided on the upper end of the sliding plate 3, and the sample storage barrels 4 are used to store samples, and then slide into the detection box 1 with the sliding plate 3 to reach the detection area inside the detection box 1, and a barrel cover 6 matched with the sample storage barrel 4 is connected to the upper end of the sliding plate 3 through a rotating shaft 5, and the rotating shaft 5 is connected to the sliding plate 3 A torsion spring 26 is provided at the rotating connection. When the barrel cover 6 is covered on the sample barrel 4, it can effectively prevent the fluorescent whitening agent from flying during the movement of the sample barrel 4 driven by the sliding plate 3. A support frame 7 matching the sliding plate 3 is provided on the bottom surface of the detection box 1. A driving component is provided on the inner side of the support frame 7 for first driving the sliding plate 3 to slide into the detection box 1 and then driving the rotating shaft 5 to deflect so that the barrel cover 6 is opened. The driving component starts to drive the sliding plate 3 to move into the detection box 1 until one end of the sliding plate 3 abuts against the inner wall of the detection box 1. At this time, it reaches the detection area, and then the driving component is operated to drive the rotating shaft 5 to rotate so that the barrel cover 6 is opened, so as to prepare for subsequent detection;

[0040] It also includes a snap-on assembly that cooperates with the driving assembly. A plug-in column 21 is fixedly provided at the lower end of the two sample barrels 4. The plug-in column 21 is coaxially arranged with the sample barrel 4. The lower ends of the two plug-in columns 21 movably penetrate the sliding plate 3 and the outer surface is provided with a snap-on groove that cooperates with the snap-on assembly. When the snap-on assembly is snap-fitted with the snap-on groove, the plug-in column 21 is restricted from being pulled out upward. When the snap-on assembly is driven by the driving assembly, it will gradually disengage from the snap-on groove, releasing the limiting fixation of the plug-in column 21, making it convenient for the staff to quickly disassemble the sample barrel 4 for cleaning and replacement.

[0041] The outer side of the support frame 7 is provided with a motor 38 for driving the screw rod 9 to rotate, and the output shaft of the motor 38 is connected to one end of the screw rod 9 through a coupling. The outer side of the screw rod 9 is threadedly connected with a moving block 10 for driving the sliding frame to slide. The lower end of the sliding plate 3 is fixed with a mounting block 13, and the mounting block 13 is slidably connected to the sliding frame through a slide rail 16. The number of the slide rails 16 is two, and the two slide rails 16 are distributed in parallel and are respectively fixed on the upper end surfaces of the long plate 11 and the connecting plate 12. The cross section of the slide rail 16 is T-shaped, and the slide rail 16 is fixedly connected by a hexagon socket bolt. The slide rail 16 is formed with a countersunk hole for installing the hexagon socket bolt, so that the rear end of the hexagon socket bolt is embedded in the countersunk hole, and the lower end of the mounting block 13 is slidably provided with an L-shaped plate 17. The mounting block 1 The lower end of the mounting block 13 is formed with a sliding cavity for the sliding of the L-shaped plate 17, the upper end of the mounting block 13 is formed with a mounting cavity, the bottom surface of the mounting cavity is movably penetrated by a T-shaped mounting rod 18, the smaller end of the T-shaped mounting rod 18 is threadedly connected to the upper end of the L-shaped plate 17, a first spring 19 is provided between the larger end of the T-shaped mounting rod 18 and the bottom surface of the mounting cavity, the bottom surface of the detection box 1 is provided with a groove 34 that matches the L-shaped plate 17, the inner side of the sliding frame is fixedly provided with an extrusion plate 14 for extruding the L-shaped plate 17 into the groove 34, and the lower end of the rotating shaft 5 is provided with a transmission member that matches the sliding frame. When the L-shaped plate 17 is misaligned with the groove 34, the extrusion plate 14 cannot drive the L-shaped plate 17 to move downward, and the sliding frame drives the sliding plate 3 to slide into the detection box 1. When the sliding plate 3 abuts against the inner wall of the detection box 1, that is, reaches the detection area, the L-shaped plate 17 is aligned with the groove 34, and then the sliding frame continues to move, so that the extrusion plate 14 moves and squeezes the L-shaped plate 17 (refer to the attached manual Figure 4-6 ), so that the lower end of the L-shaped plate 17 is inserted into the groove 34, and when the sliding frame continues to move, the sliding frame and the mounting block 13 produce relative displacement. At this time, under the cooperation of the sliding frame and the transmission member, the rotating shaft 5 will be driven to rotate, thereby opening the barrel cover 6 to prepare for the subsequent sample detection.

[0042] Furthermore, the snap-on assembly includes a mounting shell 24 fixed to the lower end of the sliding plate 3, the mounting shell 24 is welded and fixed to the sliding plate 3 or fixedly connected by screws, one side of the mounting shell 24 is open and slidably provided with a snap-on plate 22, and the snap-on plate 22 is connected to the inner wall of the mounting shell 24 through a second spring 25.

[0043] Furthermore, a rectangular opening 15 cooperating with the moving block 10 is provided on one side of the long plate 11, and a limit piece cooperating with the moving block 10 is elastically connected to the lower end of the rectangular opening 15, and the limit piece includes a limit rod 35 movably penetrating the inner bottom surface of the rectangular opening 15 and a mounting hole provided on the inner bottom surface of the rectangular opening 15, and a pressure block 20 squeezed by the moving block 10 is provided at one end of the limit rod 35, and the pressure block 20 is hemispherical and connected to the inner bottom surface of the mounting hole through a fourth spring 36, and a limit hole 33 cooperating with the limit rod 35 is provided on the inner bottom surface of the detection box 1, and a baffle 8 is fixed on the inner bottom surface of the detection box 1 to limit the movement of the sliding frame so that the limit rod 35 is aligned with the limit hole 33. When the detection is completed, the driving assembly drives the sliding frame and the sliding plate 3 to move toward the outside of the detection box 1 (refer to the attached manual Figure 7 ), since the limiting rod 35 and the limiting hole 33 are in a misaligned state, the moving block 10 will not slide relatively in the rectangular opening 15. Therefore, when the screw rod 9 drives the moving block 10 to move, it drives the sliding frame to move. Since the barrel cover 6 is in an open state during the detection, and the lower end of the L-shaped plate 17 is stuck in the groove 34, the sliding frame will first release the squeeze on the transmission member when it moves, so that the rotating shaft 5 is reset under the action of the torsion spring 26, that is, the barrel cover 6 is deflected and closed, and the upper end of the sample storage barrel 4 is closed, and then as the sliding frame moves, the barrel cover 6 is deflected and closed. The movement of the frame will cause the extrusion plate 14 to gradually release the extrusion on the L-shaped plate 17, and then the L-shaped plate 17 will gradually disengage from the groove 34 under the reset action of the first spring 19, and then the sliding frame will continue to move, and with the cooperation of the connecting plate 12 and the L-shaped plate 17, it will drive the L-shaped plate 17, the mounting block 13 and the sliding plate 3 to move, that is, drive the sample storage barrel 4 to move toward the outside of the detection box 1. When the sliding member abuts against the baffle 8, the limiting rod 35 is aligned with the limiting hole 33, preparing for the subsequent sliding of the moving block 10 in the rectangular opening 15.

[0044] Further, the transmission member includes a housing 23 and a transverse plate 27 slidably arranged inside the housing 23, the transverse plate 27 is connected to the inner bottom surface of the housing 23 through a third spring 29, the transverse plate 27 is rotatably connected to the rotating shaft 5 through a bearing, the torsion spring 26 is located between the transverse plate 27 and the sliding plate 3, a spiral groove 30 is opened at the lower end of the outer surface of the rotating shaft 5, a sleeve 32 is fixedly provided on the inner bottom surface of the housing 23, and a convex block 31 matching the spiral groove 30 is provided on the inner wall of the sleeve 32, an extrusion block 28 for extruding the clamping plate 22 so that the clamping plate 22 is separated from the clamping groove is provided at the upper end of the housing 23, and a flange 28 for engaging with the housing 23 is opened on one side of the moving block 10. The lower end surface cooperates with the slope 37. When in use, the sliding frame moves toward the inside of the detection box 1 and drives the sliding plate 3 to reach the detection area. The sliding frame continues to move to squeeze the shell 23, thereby driving the shell 23 and the cross plate 27 to rotate as a whole, and then drives the rotating shaft 5 to rotate, so that the barrel cover 6 is deflected and opened. When the sliding frame moves toward the outside of the detection box 1 until it abuts against the baffle 8, the screw rod 9 continues to rotate to drive the moving block 10 to slide in the rectangular opening 15. The movement of the moving block 10 causes the slope 37 to gradually squeeze the lower end of the shell 23, so that the shell 23 moves upward (refer to the attached manual). Fig.14 ), the upward movement of the shell 23 drives the sleeve 32 to move upward, thereby causing a relative displacement between the sleeve 32 and the rotating shaft 5, and under the cooperation of the protrusion 31 and the spiral groove 30, the rotating shaft 5 is rotated. At the same time, the upward movement of the shell 23 drives the extrusion block 28 to move upward, and the upward movement of the extrusion block 28 squeezes the clamping plate 22, so that the clamping plate 22 moves into the mounting shell 24, thereby disengaging the clamping plate 22 from the clamping groove, that is, when the sliding plate 3 drives the sample storage barrel 4 to move toward the outside of the detection box 1, on the one hand, the barrel cover 6 is opened, and on the other hand, the clamping plate 22 is disengaged from the clamping groove, thereby releasing the limit fixation of the sample storage barrel 4, thereby facilitating the disassembly and replacement of the sample storage barrel 4.

[0045] Furthermore, the plug-in column 21 is square, which effectively prevents the sample storage barrel 4 from rotating. The snap-in groove is annular, so that the plug-in column 21 does not need to deliberately adjust the orientation of the snap-in groove during the plug-in process, and the snap-in plate 22 can be snapped into the snap-in groove. The lower end edge of the plug-in column 21 is chamfered to facilitate the plug-in column 21 to quickly pass through the through hole reserved on the sliding plate 3.

[0046] Furthermore, an ultraviolet lamp and a camera are provided inside the detection box 1. Ultraviolet rays have special optical properties. When irradiated to a substance containing a fluorescent whitening agent, the fluorescent whitening agent will absorb the energy of the ultraviolet rays and then re-emit it in the form of visible light, producing an obvious fluorescence phenomenon. The camera is responsible for capturing this fluorescence phenomenon. Through a highly sensitive image sensor, the camera can accurately record the fluorescent image emitted by the object under ultraviolet irradiation. A controller and a display screen are provided on the outside of the detection box 1. The ultraviolet lamp and the camera are electrically connected to the controller respectively, and the display screen is electrically connected to the controller. The controller analyzes the data and then the detection structure is displayed through the display screen.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
