Description

Clear useless device of cardboard Technical Field The invention relates to the technical field of corrugated paper production equipment, in particular to a paperboard waste removing device. Background The composition mechanism of the corrugated paper printing production linkage line generally comprises a paper feeding unit, a plurality of printing units, a slotting unit, a die cutting unit and the like, wherein the units work together in a unified and coordinated mode under the action of a power system and a transmission system, and a series of processing operations such as paper feeding, printing, slotting, die cutting and the like of corrugated paper boards are completed together. In the production process, when corrugated paper printed products pass through the procedures of die cutting, slotting and the like, in order to accelerate the die cutting speed of corrugated paper, the current die cutting unit adopts an incomplete cutting mode, namely, after die cutting, all corrugated paper printed products are adhered with rim charge through fine toothed blocks. Therefore, a waste removal process is also required after the die-cutting is completed. In order to separate each adhered corrugated paper printing product from rim charge and clean rim charge scraps, in the prior art, a patent with the publication number CN113878657B discloses an independent multi-stage waste cleaning device and method for a corrugated paper printing production linkage line, wherein a first waste cleaning mechanism, a second waste cleaning mechanism and a third waste cleaning mechanism are respectively arranged on a frame and are sequentially arranged above a paperboard conveying mechanism along the paperboard conveying direction, the first waste cleaning mechanism and the third waste cleaning mechanism are respectively wind-type waste cleaning mechanisms, the second waste cleaning mechanism is a brush type waste cleaning mechanism, and a waste blocking plate is further arranged between the first waste cleaning mechanism and the second waste cleaning mechanism. The method comprises the steps of firstly carrying out wind power to remove most waste paper scraps through a first waste removing mechanism, isolating the waste paper scraps through a waste baffle, then carrying out further cleaning through a brush type second waste removing mechanism to separate the waste paper scraps adhered to the surface of the paperboard, and then removing the separated waste paper scraps through wind power through a third waste removing mechanism. However, in the actual production process, the adhesion strength of the toothed blocks between the corrugated paper printed matters with different specifications is different, and the situation that the adhesion is more tight can occur due to uneven die cutting pressure or the characteristics of paper per se in part of the corrugated paper printed matters, the existing combined mode of wind power waste removal and brush waste removal is difficult to effectively cut off the intractable adhesion points, so that the adjacent corrugated paper printed matters are still easy to be involved in each other in the subsequent conveying or stacking process, the flatness and the separation efficiency of the products are not only influenced, but also the edge breakage or deformation of the printed matters can be caused due to forced pulling, and the defective rate is increased.
