The utility model relates to PVC section bar technical field, and disclose a kind of PVC section bar milling groove tool, including workbench, the top of workbench is provided with recess, the inner wall of recess is fixedly connected with support leg, the top of support leg is fixedly connected with placing plate, cleaning mechanism is provided on the workbench, and the cleaning mechanism includes side plate, guide rail, linear motor, telescopic link, mounting bracket, first spring, cleaning roller.The utility model linear motor drives cleaning roller to move along section bar surface, cooperate the elastic compression of first spring, ensure that cleaning roller and section bar surface are closely attached, effectively wipe water vapor and attached impurity, avoid milling when chippings because of damp agglomerate and block cutter, hot air blower is sent hot air to the section bar surface after cleaning by air outlet pipe, accelerate residual water vapor evaporation, reduce section bar surface moisture content, solve chippings sticking problem from root when milling groove in damp environment, improve milling groove precision.

The invention relates to the technical field of wastewater treatment, and discloses industrial wastewater treatment equipment with a water quality detection function, which comprises an air flotation machine main body, a water quality detector mounted in the air flotation machine main body and a slag scraping assembly mounted on the air flotation machine main body, the slag scraping assembly comprises a conveying belt and a slag scraping plate fixedly installed on the conveying belt, a mounting frame is fixedly installed on the air flotation machine body, cylindrical scraping plates are rotationally installed on the side, located on the conveying belt, of the mounting plate and the mounting shell correspondingly, and the two cylindrical scraping plates make sliding contact with the upper side and the lower side of the conveying belt correspondingly; the cylindrical scraping plate is used for scraping off fixed particles on the surface of the conveying belt, due to the geometrical characteristics of the cylindrical scraping plate, part of scraped impurities can fall onto dross below, part of the scraped impurities can adhere to the cylindrical scraping plate, and when the dross scraping plate passes through one side of the cylindrical scraping plate, a first push plate and a second push plate on the dross scraping plate can push corresponding cross-shaped push plates to rotate, so that the dross can be scraped off. And different arc-shaped surfaces are updated for subsequent slag scraping.

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.
