This utility model discloses a vegetable drying conveyor belt cleaning device, which relates to the field of vegetable conveying technology. The device includes a support frame, with a conveyor belt for transporting vegetables mounted inside the support frame. A mounting frame is fixedly installed on one side of the bottom of the support frame. It also includes a high-temperature sterilization mechanism, which includes a cleaning roller mounted inside the mounting frame. By using a water pump, spray plate seat, cleaning roller, conveying pipe, motor, and heating pipe in conjunction, the device achieves contact cleaning of the conveyor belt surface. This solves the problem of the conveyor belt in the drying room generating sugary sap and adhesive force that causes vegetable debris to stick, easily leading to conveyor belt contamination. Simultaneously, the heating pipe, in conjunction with the spray plate seat, enables the use of high-temperature water to disinfect and sterilize the cleaning roller.

The utility model relates to a dust removal device for semiconductor lead frame processing. The dust removal device comprises a fixed seat, adjusting assemblies are arranged on the side wall of the fixing base. The fixing base is provided with a dust collection assembly through an adjusting assembly. The fixing base is provided with a sealing assembly through a dust collection assembly. Multiple groups of fixing bolts are arranged in the middle of the fixing seat; the adjusting assembly comprises a sliding plate, a first servo motor, a first lead screw, a second servo motor and a second lead screw. The first servo motor is fixedly connected to the top of the fixed seat; the first lead screw is fixedly connected to the transmission end of the first servo motor. Through the above structure, the dust collection assembly covers the semiconductor lead frame and carries out dust removal, the semiconductor lead frame processing dust removal structure is formed, the function of removing dust on the surface of the semiconductor lead frame is achieved, and the problem that dust falls on the semiconductor lead frame to cause smudginess of the semiconductor lead frame is solved; the cleanliness of the surface of the semiconductor lead frame is improved, and the situation that the yield is reduced due to the fact that dust adheres to the semiconductor lead frame is reduced.
