On this basis, further purpose of the present invention provide corresponding two bottom knife rollers of a kind of stationary knife roller, both can effectively simplify machine frame for movement and form and reduce manufacturing cost, guarantee that again its operating space increases, manipulates more convenient, safer face tissue folding machine cutting roller group.
The objective of the invention is to be achieved through the following technical solutions:
A kind of face tissue folding machine cutting roller group, be characterized in that described cutting roller group comprises at least one stationary knife roller and at least one bottom knife roller, its axial direction of wherein said bottom knife roller upper edge is provided with the governor motion of at least three driven bed plate liftings spaced apart, and the other suction hole group that is provided with vacuum suction of each governor motion.
Wherein, above-mentioned governor motion comprises adjustment hole, the regulating block that is installed on the driven bed plate lifting in the adjustment hole that is arranged on the bottom knife roller, the adjustment screw that is installed on the made regulating block lifting between regulating block and the adjustment hole.
For realizing further purpose of the present invention, above-mentioned cutting roller group comprises a stationary knife roller and two bottom knife rollers that are positioned at its below, and described stationary knife roller is provided with two stationary knifes, this two stationary knife respectively with two bottom knife rollers of its below on the corresponding cooperation of bed plate.Wherein, for guaranteeing body paper reliability of cutting off and the neat that guarantees its section, above-mentioned two stationary knifes are splayed and are distributed on the stationary knife roller, make stationary knife roller, bottom knife roller when carrying out the cut-out of body paper, and corresponding stationary knife group and bed plate are the scissor type motion.
But the present invention is because the bottom knife roller structure that adopts the bed plate multiple spot to regulate, each section of each bed plate on the bottom knife roller all can be regulated respectively, thereby the stationary knife edge of a knife that the edge of a knife that makes each section bed plate is corresponding with it can closely cooperate, and form the shear pressure of uniformity, thereby effectively and reliably adapt to and compensate the edge of a knife shear pressure uneven problem of stationary knife because of being out of shape or being caused when relatively poor because of the uniformity of each bed plate.The edge of a knife shear pressure that fully guarantees stationary knife, bed plate is adjustable to optimum state, has both made stationary knife, bed plate is more durable and prolong its service life.Can under the situation of position that does not change double vacuum suction hole and size, regulate easily and reliably again.And it is good to have folding effect, advantage of high production efficiency.Simultaneously, further the certain rotor that adopts is provided with the structure of two stationary knifes, make the present invention can easily and reliably realize the structure of corresponding two bottom knife rollers of a stationary knife roller, both simplify the frame for movement composition of machine and reduced its production cost, effectively increase its operating space again, guarantee more convenient operation and safer.
Describe realization of the present invention in detail below in conjunction with accompanying drawing:
