Marking press for corrugated paper

Abstract

The invention provides a marking press for corrugated paper. The marking press comprises a longitudinal marking device, a prepressing wetting device, a front conveying device and a rear conveying device, wherein the longitudinal marking device comprises two upright columns arranged symmetrically, a cross rod, air cylinders, a pressing roll, pressing wheels and a supporting roll; the cross rod is arranged at the top ends of the two upright columns; the air cylinders are arranged on the cross rod; output rods of the air cylinders are connected with shaft sleeves; the pressing roll is rotationally mounted in the shaft sleeves; axial positions of the pressing wheels on the pressing roll are adjustable; the prepressing wetting device comprises two connecting rods arranged symmetrically, a rotating roll, prepressing wheels, spongy layers and first water spray pipes; the prepressing wheels are arranged on the rotating roll, and correspond to the pressing wheels one to one; axial positions of the prepressing wheels on the rotating roll are adjustable; the widths of prepressing wheels are greater than those of the pressing wheels; the spongy layers are arranged on the outer sides of rolling surfaces of the prepressing wheels; and water outlets of the first spray water pipes are formed above the rotating roll. The marking press is wide in application scope; pressing marks have various forms; the depths of the pressing marks are controllable; and no tearing can be caused at a pressing mark place in a marking process.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to a creasing machine for corrugated paper. Background technique [0002] Corrugated paper is a kind of paper product commonly used to make packing boxes. In the process of making packing boxes, the corrugated paper needs to be folded in half. Because the corrugated paper is relatively hard, it needs to be creased before folding it in half. [0003] In the existing corrugated paper creasing device, there are disadvantages such as shallow indentation, weak pressure, low forming efficiency, and the creasing process of the pressing wheel is easy to cause tearing on the indentation. [0004] The Chinese patent application No. 201330142456.7 discloses an improved structure of a corrugated cardboard production line, including a conveyor belt and a creasing machine. A nozzle is fixed in front of the two creasing wheels of the creasing machine at a position higher than the conve...

AI Technical Summary

Problems solved by technology

[0003] In the existing corrugated paper creasing device, there are shortcomings such as shallow indentation and weak pressure, and the forming efficiency is low. During the creasing process, the pressure wheel is easy to cause tearing on the creasing.

[0004] The Chinese patent application No. 201330142456.7 discloses an improved structure of a corrugated cardboard production line, including a conveyor belt and a creasing machine. A nozzle is fixed in front of the two creasing wheels of the creasing machine at a position higher than the conveyor belt. Each nozzle The pipes are respectively connected with the spraying device, which overcomes the defect that the cardboard is brittle and is prone to cracking near the creasing line. However, the wetting range and degree of wetting are not easy to control when spraying the corrugated paper. The infiltration effect of the fog is not good
