The invention relates to the technical field of coal mine safety detection equipment, and provides a mining intrinsic safety type aerial fog spraying controller which comprises a rod tail seat, the top of the rod tail seat is connected with a telescopic rod piece, the top of the telescopic rod piece is connected with a handle pipe, the outer side of the handle pipe is connected with a handle cover, and the top of the handle pipe is connected with a first mounting plate. The two ends of the top of the first mounting plate are connected with connecting rods, the tops of the two connecting rods are connected with a shell, the outer side of the shell is connected with a control panel, a gas cylinder is connected between the two connecting rods, the top of the shell is connected with a second mounting plate, one end of the top of the second mounting plate is connected with an electromagnetic valve, and the outlet end of the electromagnetic valve is connected with a movable connector. The outlet end of the movable connector is connected with a smoke outlet nozzle, and the other end of the top of the second mounting plate is connected with a heating head. The technical defects of a traditional aerial fog spraying controller are comprehensively overcome through the height-adjustable telescopic rod piece, the direction-flexible spraying head, the uniform heat source design, the real-time monitoring system and safe and portable operation.

This invention discloses a packaged food sorting device and method, belonging to the field of food bottle and can sorting technology. The packaged food sorting device includes two vision inspection devices fixed to the front and back surfaces of a frame. The frame surface is provided with a conveying assembly for distributing bottles and cans in a stepped manner in front of the vision inspection devices. The frame surface is also provided with an interception assembly for intercepting bottles and cans in front of the vision inspection devices. The interception assembly includes two intercepting rods disposed on the surface of a connecting block. By setting the conveying assembly, the bottles and cans are raised to different heights as they pass through the first and second lifting sections, allowing multiple bottles and cans to be distributed in a stepped manner in front of the vision inspection devices. The vision inspection devices inspect the tops and sidewalls of the bottles and cans at an angle, avoiding mutual obstruction and enabling simultaneous inspection of multiple bottles and cans without creating blind spots.

The utility model discloses a model surface flaw detection device for 3D printing, and belongs to the technical field of model surface flaw detection devices for 3D printing, and the technical scheme is characterized in that the model surface flaw detection device comprises a placing assembly, the top of the placing assembly is fixedly connected with a frame, and a plurality of first acrylic plates are arranged in the frame; a detection assembly is arranged in the frame; the detection assembly comprises a first servo motor, the bottom of the first servo motor is fixedly connected with a hollow plate, the bottom of the hollow plate is provided with an adjusting groove, and the interior of the hollow plate is fixedly connected with a second servo motor. The problems that in the prior art, some models may have cavities, most existing camera structures are straight-up and straight-down structures, under the condition that the models are detected, after one side is detected, manual adjustment is needed again, and the workload is increased are solved.

This utility model discloses a glassware appearance inspection device, belonging to the field of glassware inspection technology. It includes a base, on which an inspection box is fixedly installed. Support rods are installed at the four corners of the inspection box, and a movable plate is slidably installed on each support rod. An electric turntable is installed on the movable plate, and a rotating rod is connected to the turntable. A placement plate is installed on the rotating rod, and fixed plates are symmetrically installed on the placement plate. In this glassware appearance inspection device, the movement of the support plates compresses a spring. The glassware to be inspected is then placed on the placement plate. Releasing the pull rod causes the spring force to be transmitted through the support plate to the fixing sponge, thus clamping and fixing the glassware on the placement plate. After closing the protective door and turning on the electric turntable and inspection light, the glassware can be inspected from all angles, avoiding blind spots in the inspection.
