Abstract

The invention discloses a paper collecting device of an offset press. According to the paper collecting device, a conveying belt is arranged, a plurality of through holes are formed in the conveying belt, the conveying belt is driven by a first motor, a two-way lead screw is arranged above the conveying belt, two sliding blocks are arranged on the two-way lead screw in a sleeving mode, and pressing rollers are fixedly arranged at the bottoms of the two sliding blocks, so that when paper is conveyed on the conveying belt, downward pressure is applied by the pressing rollers, the situation that the conveying efficiency is affected due to displacement of the paper in the conveying process is avoided, a plurality of fans are arranged on the conveying belt and below the conveying belt, the fans can generate hot air to dry the paper, ink drying is accelerated, and ink permeation between the paper is prevented; and through arrangement of the two-way lead screw, the two-way lead screw can be driven by a second motor, and the two-way lead screw is driven by the second motor to rotate, so that the two sliding blocks move close to each other or move away from each other, the distance between the two pressing rollers can be adjusted, the two pressing rollers can adapt to paper of different sizes, and the applicability of the paper collecting device is enhanced.

Description

technical field [0001] The invention belongs to the technical field of paper delivery devices, and in particular relates to a paper delivery device of an offset printing machine. Background technique [0002] The function of the delivery device of the offset printing machine is to transfer the printed sheets from the printing part and transfer them to the delivery table, and then collide them and stack them neatly on the delivery table to prepare for the subsequent operation. Most of the existing printing machine conveying devices adopt belt or roller conveying mechanism, which are arranged under the newly printed paper according to a certain gap for conveying, but the conveying mechanism has the disadvantages of easily skewing the paper, staining the imprint and poor accuracy, etc. Therefore, it is generally collected manually. In the process of paper collection, mistakes are prone to occur, resulting in uneven paper, affecting subsequent operations, low work efficiency, ti...
