The Corrugated Cardboard Production Line Main Machine Details

ZJ-V5B hydraulic shaftless mill roll stand

Adopt hydraulic drive to complete the paper clamping, loose, move for the medium, left and right，the lifting of the paper adopts hydraulic drive.
Brake adjustable adopts multipoint braking system.
Every stand matched two sets paper trolley , and they can load the paper on the both sides at the same time.

RG-1-900 paper preheater

Preheat roller accord the pressure container national standards, and enclose the pressure container certificates and inspection certificate.
Each roller surface after grinding precision grinding and dealing with hard chrome plating, Surface friction is small, durable.
Electromotion adjustment angle, and angle can rotation adjustment the preheat area in the range of 360°.

SF-320C fingerless type single facer
