For achieving the above object, a kind of rolling cutting knife device, comprise frame, cutter rack and cut-off knife, cut-off knife is arranged on cutter rack; Cutter rack is provided with the cutter mechanism of more than a group; Described cutter mechanism comprises drive unit, gear wheel, pinion, connecting rod and cut-off knife arm plate; Drive unit is located in frame, and drive unit drives gear wheel motion; Gear wheel is meshed with pinion; Pinion is articulated in frame by arm shaft; One end of connecting rod is articulated in frame, and the other end of connecting rod is articulated on cutter rack; One end of cut-off knife arm plate is connected on pinion, and the other end of cut-off knife arm plate is articulated on cutter rack.
Further, described drive unit is cylinder, and described gear wheel is sector gear; Frame is provided with the first a fixed pivot axis and the second a fixed pivot axis; The cylinder body of cylinder is articulated on the first rigid bearing, and the piston rod of cylinder is articulated in the middle part of sector gear; Sector gear is articulated on the second a fixed pivot axis away from one end of the gear teeth.
Further, described knife rest comprises tool holder body and pendulum pawl, and pendulum pawl is fixed in tool holder body; The other end of connecting rod is articulated on pendulum pawl.
Further, cut-off knife arm plate is positioned at the front of connecting rod.
Further, frame is provided with the 3rd a fixed pivot axis, one end of connecting rod is articulated on the 3rd a fixed pivot axis.
The beneficial effects of the utility model are:
(1) in the utility model, gear wheel motion is driven by drive unit, gear wheel drives cut-off knife arm sweep by pinion, cutter rack motion is moved by cut-off knife arm strip, thus drive cut-off knife motion, to realize driving cutter rack to swing fast, finally reach the object that cut-off knife cuts off raw material, this improves the movement velocity of cut-off knife.
(2) owing to being provided with connecting rod, cut-off knife arm plate and cutter rack, above-mentioned three parts constitute brace and connecting rod framework, ensure that the blade of cut-off knife is little as far as possible with the variable angle of material strip in the process cutting off material strip, thus reach best fracture effect.
(3) adopt the motion of air cylinder driven sector gear, swinging back and forth of sector gear can be realized easily, thus realize that cut-off knife moves back and forth cut action.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As depicted in figs. 1 and 2, rolling cutting knife device comprises the cutter mechanism of frame (not shown), cutter rack, cut-off knife 1 and more than a group.
Frame is installed the first a fixed pivot axis 13, second a fixed pivot axis 15 and the 3rd a fixed pivot axis 8.According to the view directions of Fig. 1 and Fig. 2, the second a fixed pivot axis 15 is positioned at the lower left of the first a fixed pivot axis 13, and the 3rd a fixed pivot axis 8 is positioned at the upper left side of the first a fixed pivot axis 15, and the 3rd a fixed pivot axis 8 is positioned at the top of the second a fixed pivot axis 13.
Cutter rack comprises cutter rack body 3 and pendulum pawl 14, and cutter rack body 3 is fixed on the front end of pendulum pawl 14; Cut-off knife 1 is fixed on cutter rack body 3.
In the present embodiment, cutter mechanism is two groups.Described cutter mechanism comprises drive unit, gear wheel, pinion 6, connecting rod 9 and cut-off knife arm plate 4.
Described drive unit is cylinder 12, and the cylinder body of cylinder 12 is articulated on the first a fixed pivot axis 15.In the present embodiment, gear wheel is sector gear 7, and one end of sector gear 7 has the gear teeth, and sector gear 7 is articulated on the second a fixed pivot axis 15 away from one end of the gear teeth, and the piston rod of cylinder 12 is articulated in the middle part of sector gear 7 by the first bearing pin 10.Frame is provided with arm shaft 5, and all cutter mechanisms share described arm shaft 5, and according to the view directions of Fig. 1 and Fig. 2, arm shaft 5 is positioned at the left side of the 3rd a fixed pivot axis; Pinion 6 is articulated on arm shaft 5, and pinion 6 is meshed with sector gear 7.One end of connecting rod 9 is articulated in the 3rd a fixed pivot axis 8, and the other end of connecting rod 9 is articulated by the second bearing pin 11 and pendulum pawl 14.One end of cut-off knife arm plate 4 is fixed on pinion 6, and the other end of cut-off knife arm plate 4 is articulated on cutter rack body 3 by the 3rd bearing pin 2.
The operation principle of above-mentioned rolling cutting knife device is: when the piston rod of cylinder 12 travels forward, sector gear 7 is promoted around the second a fixed pivot axis 13 forward rocking motion by cylinder piston rod, sector gear 7 drives cut-off knife arm plate 4 to rotate around arm shaft 5 by pinion 6, allow the other end forward rocking motion of cut-off knife arm plate 4, under the effect of connecting rod 9, pendulum pawl 14, cutter rack body 3 travels forward fast, thus drive cut-off knife 1 to travel forward fast, reach the object of fast shut-off raw material, make the quality that cuts good.
When the piston rod of cylinder 12 moves backward, cut-off knife 1 is driven to move backward by sector gear 7, pinion 6, cut-off knife arm plate 4, cutter rack body 3.
As said process, cylinder moves repeatedly, then cut-off knife can be driven to move back and forth.
In the present embodiment, owing to being provided with connecting rod 9, cut-off knife arm plate 4, pendulum pawl 14 and cutter rack body 3, above-mentioned four parts constitute brace and connecting rod framework, ensure that the blade of cut-off knife is cutting off change little as far as possible with the angle of material strip in the process of material strip, thus reach best fracture effect.
