Corrugating Single Facer

Sfm25n positive pressure cassette type single facer

Effective width：1400-2500 mm

Specification：

1.Maximum mechanical speed is 250m/min.

2.The diameter of the corrugating rollers is F380 mm. The diameter of the pressure roller is F520 mm. The diameter of the surfaces of glue roller is F302 mm, The diameter of the doctor roller is F170mm.

3.The machine adopts positive pressure air cushion paper guide, with high utilization of heat energy, and good quality of corrugated shaping。

4.Corrugated roller adopts positive pressure cassette type. It’s under the pressure roller, so as to lower the center of gravity of the machine. It’s smooth when under high-speed operation, and reduces vibration, so it’s more stable and smooth during operation. Corrugated roller exchange is saver and faster.

5.Corrugated roller, pressure roller and glue roller adopts individual driving reduction box, to isolate vibration. The oil immersion lubrication and high precision gear driving ensure stable and reliable during operation.

6.Corrugated roller sets get in and out hydraulic automatically, so as to exchange different flutes rapidly.

7.Individual glue section could move out from the main machine, and it’s easy to clean and maintain. An electric glue partition device is provided to give convenient and rapid paper width adjustment. 

8.The glue roller has low speed auto-rotate function, so as to avoid the glue dry on the glue roller.

9.A frequency conversion motor is used to supply power, realizing stepless speed adjustment and reliable and synchronous interlock with the following devices. The frequency converter used is an international famous brand product with stable and reliable performance and low failure rate.

10.All bearings of the upper and lower corrugated rollers, and pressure roller adopt high temperature grease, so as to guarantee long life and smooth running of the rollers.

11.The opening and closing of corrugated rollers, pressure rollers, glue rollers, and the locking of corrugated roller set are all hydraulic controlled.

12.There is a face paper pre-heating roller and core paper pre-heating roller in this machine. The pre-heating cylinder could rotate automatically and it is equipped with a manual braking device. There is a conditioning steam injector for core paper installed in the machine.

13.This machine is PLC controlled, and displayed by big color touch-screen. Machine status is displayed by animated image, to achieve strong failure diagnosis ability and operation guiding..

14.The gap adjustment between corrugated roller and pressure roller are hydraulic controlled, and the gap adjustment between corrugated roller and glue roller are electric controlled.

15.The machine is equipped with an automatic plc glue adjustment system.
