Paper folding machine conveyer belt compression roller device

Abstract

The invention discloses a paper folding machine conveyer belt compression roller device and belongs to the field of printing mechanical equipment. The paper folding machine conveyer belt compression roller device comprises a roller body and a bracket, wherein the roller body is arranged above a conveyer belt of the output folded paper of a paper folding machine; the bracket comprises two parts, and the two parts are arranged on the two sides of the conveyer belt; the shafts at the two ends of the roller body are rotatably connected with the top end of the bracket on the two sides of the conveyer belt; the roller body comprises an end part and a middle part; both the end part and the middle part are cylinder structure horizontally arranged and are fixedly connected; the diameter of the middle part is less than that of the end part; and the end part is rotatably connected with the upper surface of the conveyer belt. The paper folding machine conveyer belt compression roller device can effectively planish folded paper, prevents the folded paper from being worn and polluted, and also has the drying function to provide convenience for the following binding procedure.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to a conveyor belt pressure roller device for a folding machine. Background technique [0002] The high-speed rotary folding machine used by the printing factory folds the paper and outputs it from the conveyor belt 1 to prepare for the next binding procedure. [0003] Because the paper folded by the folding machine is often not smooth enough, such as the crease is too high or the edge is lifted, it will bring difficulties to the subsequent binding work. In addition, if the moisture content of the folding paper is too high, or if there is part of the ink that has not dried out, it is easy to smudge the paper during binding and make the machine difficult to operate. [0004] In the prior art, the roller bodies used to flatten paper are mostly metal roller bodies or rubber roller bodies, which are heavy, and the diameter of the middle part of the roller body is the same as...

AI Technical Summary

Problems solved by technology

[0003] Because the paper folded by the folding machine is often not flat enough, such as the creases are too high or the edges are lifted, which brings difficulties to the subsequent binding work

In addition, if the moisture content of the folding paper is too high, or if there is part of the ink that has not dried out, it is easy to smudge the paper during binding and make the machine difficult to operate

[0004] In the prior art, the roller bodies used to flatten paper are mostly metal roller bodies or rubber roller bodies, which are heavy, and the diameter of the middle part of the roller body is the same as that of both ends, and the paper is easy to be dirty during the paper pressing process. Also prone to paper abrasion
