Driving tape-threading guide plate

Abstract

The invention discloses a driving tape-threading guide plate. The driving tape-threading guide plate comprises a swinging hydraulic cylinder and a swinging guide plate frame, the swinging hydraulic cylinder and the swinging guide plate frame are hinged to a straightener base, the head of a piston rod of the swinging hydraulic cylinder is hinged to the swinging guide plate frame, a telescopic hydraulic cylinder is installed in the swinging guide plate frame, the head of a piston rod of the telescopic hydraulic cylinder is in a transmission connection relationship with a telescopic guide plate, a scraper is fixed to the front end of the telescopic guide plate, phenolic aldehyde resin plates are laid on the upper surfaces of the swinging guide plate frame and the telescopic guide plate, multiple rows of roller chains are arranged in the swinging guide plate frame, each row of the roller chains is corresponding to a chain wheel, the side of the swinging guide plate frame is provided with a gear motor, the gear motor is in a transmission connection relationship respectively with the chain wheels by transmission shafts, and each one of chain links of all the rows of the roller chains is provided with a guide block by a pin shaft. The driving tape-threading guide plate has a simple structure and high cost performance and can improve a product yield and production benefits.

Description

technical field [0001] The invention belongs to the technical field of metallurgical steel rolling equipment, and relates to an active belt threading guide plate. Background technique [0002] In the continuous unwinding production line, the threading guide plate is located behind the uncoiler. When the unit is working, firstly, according to the outer diameter of the steel coil, the strokes of the swing hydraulic cylinder and the telescopic hydraulic cylinder are respectively controlled to make the telescopic guide plate in a suitable uncoiling position. When the uncoiler drives the coil to rotate, the scraper at the front end of the threading guide scrapes off the strip head, and the strip slides forward along the telescopic guide plate and the swinging guide frame on the threading guide, and passes through the pinch rollers of the straightening machine at the beginning to complete wear a belt. Usually, a layer of phenolic board with a thickness of about 10mm is laid on th...
