Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and a preferred embodiment.

Referring to fig. 1, the present embodiment provides a roller surface dust sucking and discharging device for a polarizer production line, which includes a forward and reverse rotation motor 32, a tank chain 33, a slide rail module, a cylinder 35, a suction nozzle 37, and a dust collector (not shown). The slide rail module includes a slide rail 361 and a slide block 362. Tank chain 33 and slide rail module pass through support 31 and locate the top of roller, and slide rail 361 is parallel with the roller, and positive and negative rotation motor 32 passes through the reciprocal rotation of speed reducer drive tank chain 33 positive and negative direction. The tank chain 33 is driven to rotate by driven rollers arranged on the support through driving rollers connected with the output shaft of the speed reducer. The cylinder 35 is fixed on the sliding block 362 and the tank chain 33 through a bracket 34; the suction nozzle 37 is fixedly mounted obliquely downwards on the cylinder piston rod, the discharge opening of the suction nozzle 37 is connected with a dust collector through a dust collecting hose (not shown in the figure), and the suction opening of the suction nozzle 3 faces the tip of the roller shaft scraper and is used for sucking dust on the surface of the roller.

In this embodiment, the suction nozzle 37 is connected to the cylinder piston rod by a rack and pinion mechanism. The gear-rack mechanism comprises a gear motor 383, a gear 382 and a rack 381, a gear shaft is fixed on a cylinder piston rod through a connecting rod, the gear 382 is driven to rotate by the gear motor 383, the rack 381 is fixed above the suction nozzle 37 in parallel, the rack 381 is connected with the connecting rod in a sliding mode, and the gear 382 is meshed with the rack 381 to form a gear-rack transmission pair. The suction nozzle 37 may be a hard nozzle made of High Density Polyethylene (HDPE), and includes a cylindrical cavity with a large rear end and a small front end, and the large cylindrical cavity and the small cylindrical cavity are transitionally connected through a tapered cavity.
