This utility model discloses a multifunctional interactive display rack for community cultural activities, relating to the field of display rack technology. It includes a display rack body, a mounting frame, and a fixing mechanism. The mounting frame is mounted on the display rack body and includes a first mounting frame and a second mounting frame. The first mounting frame is used to mount advertising boards, and the second mounting frame houses a display screen. Both are equipped with transparent panels and openable / closable covers. The covers are suspended and fixed by a first adjustable telescopic rod. The fixing mechanism includes a ring frame, a second adjustable telescopic rod, and pressure blocks. A positioning plate is inserted into a fixing slot and locked by a threaded locking rod to press and fix the advertising board, avoiding the use of adhesives. The second mounting frame also has an interactive operating table, electrically connected to the display screen, enabling residents to operate and interact. This device can stably display information about community cultural activities, combining dynamic display and interactive functions, and the advertising boards are easy to replace.

The invention belongs to the technical field of metal processing, and particularly discloses a plasma cutting device for metal material processing, which comprises a mounting frame, first frame bodies are fixedly connected to the tops of the two sides of the mounting frame, a second frame body is slidably connected between the two first frame bodies, and a third frame body is slidably connected to the outer part of the second frame body. And a cutting gun is fixedly connected to the exterior of the third frame body, an air pressure supply mechanism is arranged on one side of the exterior of the mounting frame, a dust cleaning mechanism is arranged on one side of the mounting frame, and the air pressure supply mechanism is used for reducing air pressure in the dust cleaning mechanism, so that negative-pressure dust suction of the dust cleaning mechanism is achieved. Through operation of the vibration dust discharging mechanism, vibration can be continuously generated and transmitted to the interior of the offcut storage box, so that dust in the offcut storage box can be conveniently vibrated off through vibration force, dust accumulation and hardening are avoided, and then the service life of the device box body can be prolonged.

The utility model discloses a medicine residue recycling treatment device for yellow finish machining equipment in the technical field of yellow finish machining, which is reasonable in structure, a turntable is arranged at the bottom of a sealing cover in a rotating connection manner, and a mounting hole in a filter bag is butted with a screw rod on the turntable in a sliding manner, so that the filter bag can be fixed on the turntable. According to threaded connection between the positioning head and the screw rod, after the filter bag is installed on the screw rod, the positioning head is rotated to be tightened, then the filter bag can be installed and fixed, the fixing base on the sealing cover is installed and fixed at the output end of the air cylinder, and the filter bag is placed into medicine residues before being installed and fixed. When the filter bag is rotated, the air cylinder descends the filter bag into the filter cartridge on the recovery box, the positioning head is inserted into the positioning hole in the filter cartridge, the motor drives and controls the filter cartridge to rotate at a high speed and synchronously drives the filter bag on the turntable to rotate, and the filter bag is subjected to rotary centrifugal treatment, so that medicine residues in the filter bag are effectively separated.

The utility model discloses a circuit board developing mechanism and belongs to the technical field of circuit board developing. A circuit board developing mechanism comprises a machine frame and a conveying belt which is fixedly installed on the machine frame and used for conveying a circuit board, an ash cleaning box used for cleaning floating ash and a developing box used for spraying liquid medicine are sequentially installed on the machine frame in the moving direction of the conveying belt, and the circuit board developing mechanism further comprises a partition plate fixedly installed in the middle of the top wall in the developing box. Connecting plates are symmetrically arranged at the bottom of the spacing plate in a sliding mode, and limiting blocks used for clamping a circuit board are arranged on the two sets of connecting plates in a lifting mode. According to the utility model, the circuit board can be turned over in the developing process through the spacing plate, the connecting plate and the limiting block which are matched with each other and the driving of the driving piece, so that the condition of manual turning over is reduced, the condition of non-uniform contact between liquid medicine and the circuit board is avoided, the production efficiency is improved, and the production precision is improved.
