Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the tracking roller 2 and the cross arm 4 are arranged in the front and rear direction, and the cross arm 4 has a material shaft 3 at a horizontal end portion and a guide shaft 5 at a vertical end portion. A lower cutter arm 13 is arranged on the machine frame 1 below the front part of the cross arm 4, the upper end of the lower cutter arm 13 is hinged on the machine frame 1 through a first pin shaft 15, and a first driving cylinder 12 is arranged between the lower cutter arm 13 and the machine frame 1. The middle part of the lower cutter arm 13 is hinged with a connecting rod 7, one end of the connecting rod 7 extends out from the rear part of the lower cutter arm 13, a film connecting rubber roller 6 is arranged at the extending end of the connecting rod 7, and a second driving cylinder 16 for driving the connecting rod 7 to rotate is arranged on the lower cutter arm 13. Keep away from the lower cutter arm 13 one end of hinged end and have second round pin axle 8, have the deflector roll on the second round pin axle 8, articulated on that section second round pin axle 8 between deflector roll and lower cutter arm 13 have linking arm 10, and there is cutting knife 17 in the linking arm 10 outer end, there is the third actuating cylinder 11 that is used for driving linking arm 10 pivoted on the cutter arm 13 down. The material shaft 3, the film connecting rubber roller 6 and the guide roller are all parallel to each other and are positioned in the same vertical layer.
The first pin 15 is fixed with a short plate 14 extending radially outwards, and the first driving cylinder 12 is hinged between one end of the short plate 14 far away from the first pin 15 and the frame 1.
