Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The structure of the steering pinch roller with adjustable height and drop distance of the present invention includes a frame body 11, a lifting oil cylinder is arranged at the lower end of the frame body 11, a pinch roller 2 is arranged on the lifting oil cylinder, and a steering roller a 1 is arranged directly above the pinch roller 2. A steering roller b3 is set on one side of the feed roller 2, the roller neck of the steering roller b3 is connected to the bracket 4, the bracket 4 is installed with a guide table 5, the bottom of the bracket 4 is installed with a folding cylinder 7, and the end of the folding cylinder 7 is connected to the folding guide frame 8, One end of the folding guide frame 8 close to the guide table 5 is provided with a pressing roller 6, one side of the pressing roller 6 is provided with a pin shaft 10, and the pin shaft 10 is axially connected to the folding guide frame 8; A swinging oil cylinder 9 is provided, the swinging oil cylinder 9 is connected to the bottom of the bracket 4 , and a material guide plate is arranged on the frame body 11 .

The pinch roller 2 is axially provided with a rotating shaft, one end of the rotating shaft is connected to a rotating motor, and the rotating motor drives the pinch roller 2 to rotate, bearing seats are arranged at both ends of the rotating shaft, a rotating motor is installed on the bearing seat, and the bottom of the bearing seat is connected to a lifting oil cylinder, the bearing seat Embedded in the chute on both sides of the frame body 11, the pinch roller 2 slides up and down in the frame body 11 to meet the requirements of the opening degree. The lifting oil cylinder, the motor, the folding oil cylinder 7 and the swinging oil cylinder 9 are respectively electrically connected to the steering pinch roller control system.
