[0035] The adjusting mechanism 3 is arranged on the supporting plate 14 and is used for adjusting the spraying position according to the height of the transported object.

[0036] The X-ray detection mechanism 2 includes a photoelectric camera 21 fixedly mounted on the lower wall of the support plate 14, a liquid storage tank 22 fixedly mounted on the lower wall of the support plate 14, an infusion tube 23 is provided below the liquid storage tank 22, an output end of the infusion tube 23 is connected to a nozzle 24, a drying mechanism 4 is provided directly above the nozzle 24, and the drying mechanism 4 is used to dry the paint at the marked position.

[0037] Among them, a solenoid valve is provided inside the infusion tube 23, and the photoelectric camera 21 controls the opening and closing of the solenoid valve after presenting the image to the central control board 15.

[0038] During actual inspection, the interior of the transport item can be illuminated by the photoelectric camera 21, and the image can be presented to the central control board 15. When foreign matter exists inside the transport item, the central control board 15 controls the solenoid valve in the infusion tube 23 to open, and then the paint in the liquid storage tank 22 is sprayed through the infusion tube 23 to the part of the transport item where the foreign matter exists, thereby automatically realizing foreign matter detection and marking of food and medicine.

[0039] The adjustment mechanism 3 includes a slide groove 31 provided on the support plate 14, a movable plate 32 is slidably installed in the slide groove 31, an electric telescopic rod 33 is fixedly installed below the movable plate 32, a baffle 35 is fixedly installed on the output end of the electric telescopic rod 33 through an L-shaped rod 34, a guide roller 37 is hingedly connected to the upper part of the movable plate 32 through a first hinge seat 36, two limit rods 38 are fixedly provided above the support plate 14, and an adjustment plate 39 is slidably installed on the two limit rods 38, and the guide roller 37 is in contact with the adjustment plate 39. Rolling, two extension rods 310 are fixedly installed under the adjustment plate 39, each extension rod 310 extends through and extends to the bottom of the support plate 14, and a stop block 311 is fixedly installed at the bottom of each extension rod 310. An adjustment block 313 is fixedly installed between the two extension rods 310 through a support rod 312, and the bottom of the adjustment block 313 is fixedly connected to the nozzle 24. A reset mechanism 5 is also provided under the support plate 14. The reset mechanism 5 is used to move the baffle 35 back to the initial position when the transport part continues to be transported after spraying.

[0040] The thicknesses of the two sides of the adjustment plate 39 are different, and the intersection of the two sides of the adjustment plate 39 with different thicknesses is inclined and smoothly arranged.

[0041] In view of the problem in the prior art that the spraying distance is different due to the difference in height between food and medicine, when the spraying distance is large, the paint is diffused, thereby reducing the accuracy of locating the foreign body part, the present invention sets an adjustment mechanism 3. Before spraying the mark, the transport part moves on the conveyor belt 12, and the transport part pushes the baffle 35 to move, and then drives the guide roller 37 to slide under the adjustment plate 39 through the electric telescopic rod 33 and the movable plate 32, so that the guide roller 37 moves from the position where the thickness of the adjustment plate 39 is larger to the position where the thickness is smaller, and further enables the adjustment plate 39 to move downward under the action of gravity, so that the abutment block 311 abuts against the upper surface of the transport part, thereby adjusting the height of the adjustment block 313 according to the height of the transport part, so that the distance between the nozzle 24 below the adjustment block 313 and the upper surface of the transport part remains unchanged, thereby avoiding the diffusion of the sprayed paint, so that the paint is sprayed more concentratedly on the transport part, and the accuracy of locating the foreign body parts of food and medicine is improved.

[0042] The reset mechanism 5 includes a fixed rod 51 fixedly connected to the electric telescopic rod 33. The top of the fixed rod 51 is hinged with a guide wheel 53 through a second hinge seat 52. The bottom of the support plate 14 is provided with a guide inclined plate 54. The guide wheel 53 rolls in contact with the guide inclined plate 54.

[0043] It is worth mentioning that after the spraying is completed, the baffle 35 can be driven to move upward by the electric telescopic rod 33, so that the baffle 35 no longer hinders the transportation of the transported object. At this time, the electric telescopic rod 33 will synchronously drive the guide wheel 53 to move upward, and under the action of the guide inclined plate 54, the electric telescopic rod 33 can be restored to the initial position. When the electric telescopic rod 33 drives the baffle 35 to move downward, the baffle 35 is moved back to the initial position, so that the spraying position can be readjusted according to the height of the transported object during the next transportation.

[0044] The drying mechanism 4 includes an air pipeline 41 fixedly installed above the adjusting block 313, an annular channel 42 is opened on the adjusting block 313, the air pipeline 41 is connected with the lower part of the adjusting block 313 through the annular channel 42, a rotating rod 44 is rotatably installed inside the air pipeline 41 through the mounting block 43, a plurality of fan blades 45 are fixedly installed on the rotating rod 44, a second motor 46 is provided at the bottom of the mounting block 43, the output shaft of the second motor 46 is fixedly connected to the rotating rod 44, a heating plate 47 is provided at a position below the mounting block 43 in the air pipeline 41, and a spiral belt 48 is fixedly installed on the rotating rod 44 through a connecting rod.

[0045] In view of the problem that the prior art cannot dry the paint, resulting in the paint sprayed on the surface of food and medicine being easily scratched, and the positioning effect of foreign objects being reduced, the present invention sets a drying mechanism 4. During the spraying process, the second motor 46 can drive the rotating rod 44 to rotate, and the fan blades 45 can further rotate to make the air above the air pipeline 41 flow to the bottom. The heating plate 47 heats the air so that the hot air can be sprayed on the spraying position of the transport part, and the paint at the spraying position is dried to prevent the paint from being scratched on the food surface and improve the positioning effect of foreign objects. At the same time, the rotating rod 44 will also drive the spiral belt 48 to rotate rapidly when rotating, so that the hot air is gathered between the spiral belts 48 when sprayed, so as to more fully contact with the paint, thereby improving the drying effect of the paint.

[0046] The present invention can be explained by the following operation mode:

[0047] During the inspection, the inside of the transported object is illuminated by the photoelectric camera 21, and the image is presented to the central control board 15. When there is a foreign object inside the transported object, the central control board 15 controls the electromagnetic valve in the infusion tube 23 to open, and then the paint in the liquid storage tank 22 is sprayed on the part of the transported object where the foreign object exists through the infusion tube 23;

[0048] Before spraying the mark, the transport part will push the baffle plate 35 to move, and then drive the guide roller 37 to slide under the adjustment plate 39 through the electric telescopic rod 33 and the moving plate 32, so that the guide roller 37 moves from the position where the thickness of the adjustment plate 39 is larger to the position where the thickness is smaller, and further the adjustment plate 39 is moved downward under the action of gravity, so that the abutment block 311 abuts against the upper surface of the transport part, so that the height of the adjustment block 313 is adjusted according to the height of the transport part, so that the distance between the nozzle 24 under the adjustment block 313 and the upper surface of the transport part remains unchanged, so as to avoid the diffusion of the sprayed paint, so that the paint is sprayed more concentratedly on the transport part;

[0049] During the spraying process, the rotating rod 44 is driven to rotate by the second motor 46, and the air above the air pipeline 41 flows to the bottom through the rotation of the fan blades 45. The heating plate 47 heats the air so that the hot air can be sprayed on the spraying position of the transport part, and the paint at the spraying position is dried to prevent the paint from being scratched on the food surface. At the same time, the rotating rod 44 will also drive the spiral belt 48 to rotate rapidly when rotating, so that the hot air is gathered between the spiral belts 48 when sprayed out, and is in more complete contact with the paint, thereby improving the drying effect of the paint and the positioning effect of foreign matter.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
