Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: an automatic sheet discharging device of an open mill comprises a base 1, two slide rails 2 are symmetrically arranged on the base 1, the device further comprises a shell 3, the bottom of the shell 3 is connected with the slide rails 2 in a sliding manner, a driving motor 4 is arranged on the base 1, a working shaft of the driving motor 4 is connected with a lead screw 6 which is rotatably supported on the base 1 through a shaft coupling 5, a nut block 7 is connected on the lead screw 6, the nut block 7 is connected with the inner wall of the shell 3 through a connecting frame 8,

The utility model discloses the automatic work process of piece device down of mill is as follows: after the rubber material on the open mill is supplemented and mixed, and the performance of the rubber material meets the process requirements, the device is started through a control system, firstly, a driving motor 4 is controlled to work to drive a lead screw 6 to rotate, the lead screw 6 drives a shell 3 to integrally move in the horizontal direction relative to a base 1 through a nut block 7, a circular cutter 15 and a sheet cutter 22 are close to a roller of the open mill, meanwhile, a roller motor 11 is started, and the roller motor 11 drives a driving roller 9 to rotate so as to drive a friction conveying belt 12 to act;

the shell 3 stops after moving to the limit position close to the roller of the open mill, the control system controls the first swing cylinder 18 to act, the first swing cylinder 18 can drive the first swing frame 17 to swing, and further drives the first swing square shaft 13 and the two first swing arms 14 thereon to swing, after the first swing arms 14 swing in place, the circular cutter 15 on the first swing arms just contacts with the film on the roller of the open mill and cuts the film in the width direction,

meanwhile, the control system controls the second swinging cylinder 24 to act, the second swinging cylinder 24 can drive the second swinging frame 23 to swing, so that the second swinging shaft 20 and the sheet-shaped cutter 22 on the second swinging shaft are driven to swing, the sheet-shaped cutter 22 can cut on the roller of the open mill to cut off the film wound on the roller, after the film is cut off, the second swinging cylinder 24 acts reversely, and the sheet-shaped cutter 22 returns; under the action of self-weight, the end of the film naturally hangs down and falls onto the friction conveyor belt 12, and because a certain friction force exists between the film and the friction conveyor belt 12, under the action of the friction force, the wide strip film can be stripped from the roller of the open mill by the friction conveyor belt 12 and is conveyed to the next process at the far end; in the above process, the two circular cutters 15 always cut the film;
