Air suction counting dividing device for paperboard stacking machine

Abstract

The invention belongs to the technical field of paper processing machinery and relates to an air suction counting dividing device for a paperboard stacking machine in the production of a corrugated board. The air suction counting dividing device for the paperboard stacking machine is characterized in that a fixed air suction box and a movable air suction box which are arranged below a conveying belt of the stacking machine are fixedly connected with a lighter stand; and the end part of the lighter stand at the end at which the movable air suction box is arranged is connected with a cylinder piston. When a cylinder receives a per paperboard counting command sent by a front segment transverse cutting machine to extend and retract, an exhaust opening of the movable air suction box is higher than the conveying belt of the stacking machine to be connected with a conveyed paperboard to suck a paperboard and ensure the paperboard to stop until the space between the paperboard and a previous paperboard stack reaches a required spacing, or the exhaust opening of the movable air suction box is lower than the conveying belt of the stacking machine to be separated from the paperboard without influencing the normal conveying of the paperboard. The specific paperboard is stopped or lowered by an air suction mode and the sucking-stopping separate stacking is implemented, so that the distance between the previous and next paperboard stacks is opened and the aim of accurately counting in stacks (or dividing) is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of paper product processing machinery, and relates to a cardboard stacking machine in the production of corrugated cardboard, in particular to a cardboard stacker suction counting and sorting device. Background technique [0002] At present, the counting and sorting of cardboard stacking machines mainly adopt the lifting roller (rod) method, that is, the cardboard is conveyed forward along the conveyor belt on the conveyor belt, and the lifting roller (rod) is placed under the cardboard, and the number of sheets is issued by the front cross-cutting machine ( or separate) signal, the lifting roller (rod) lifts up according to the sheet number (or separate) signal delay, and lifts the cardboard away from the conveyor belt. There is no lifting part on the front conveyor belt, the cardboard continues to move forward with the conveyor belt, and the rear lifting part stops moving forward because the cardboard leav...

AI Technical Summary

Problems solved by technology

[0003] However, because the lifting roller (rod) cannot accurately lift the designated cardboard, and it is difficult to control the lifting of the cardboard at the proper position of the cardboard, there is a certain error in the counting, and it is impossible to ensure accurate order separation: often the previous stack and the last stack of the same order The counting of a stack is inaccurate, and the counting of individual orders is inaccurate during the acceleration and deceleration of the production process
