Corrugated board production line double-face machine

Abstract

The invention discloses a corrugated board production line double-face machine and relates to the technical field of corrugated board production equipment. The corrugated board production line double-face machine comprises a thermal attaching device and a cooling device which are arranged sequentially in the paper discharge direction of a corrugated board production line. The thermal attaching device comprises an attaching support. A fixed frame is fixed to the top of the attaching support. A first transmission mechanism is rotationally connected in the fixed frame. A tensioning mechanism is arranged in the fixed frame. The cooling device comprises a conveying table. A second transmission mechanism is rotationally connected in the conveying table. A support box is fixed to the top of the conveying table. An air blasting mechanism is fixed to the top of the inner wall of the support box. According to the corrugated board production line double-face machine, through matched use of the cooling device and the air blasting mechanism, the heat dissipation speed of an attached corrugated board is increased, thus heat dissipation is more uniform, the warping phenomenon of the corrugated board during cooling is avoided, and work efficiency and production quality are improved.

Description

technical field [0001] The invention belongs to the technical field of corrugated cardboard production equipment, in particular to a double-sided machine for a corrugated cardboard production line. Background technique [0002] The double-facer is an important single machine in the corrugated cardboard production line. The main function of double-sided machine (also known as heating laminating machine) is to bond single-sided corrugated cardboard and face paper, heat and solidify, dry and cold-set to form high-quality three-layer, five-layer or seven-layer corrugated cardboard, and then The corrugated cardboard is passed to equipment such as a slitting and creasing machine to cut the cardboard; the performance of the double-facer plays a decisive role in the forming of the corrugated cardboard. [0003] The length of the conveyor belt on the existing double-facer machine is long and covers the upper surface of the cooling part of the double-facer machine as a whole, which i...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a double-sided machine for corrugated cardboard production line. By designing the double-sided machine, the length of the conveyor belt can be shortened, the heating method can be changed during bonding, and the heat dissipation speed and uniformity of heat dissipation can be improved. Increased energy consumption, heating on one side during hot lamination, uneven heating, inconsistent cooling speed during cooling, and the laminated corrugated cardboard is easy to warp the shell, which affects the quality of corrugated cardboard
