Single Facer

Model:SF20NA

Effective width:1400-2000mm


Specification:

1.The machine adopts external-suction fingerless type design; the maximum mechanical speed is 200 m/min;

2.The assembly of upper and lower corrugating rollers is installed or removed in a whole set, so it can be replaced rapidly. The diameter of the upper corrugating roller is 314 mm and that of the lower corrugating roller is 326 mm; the material of the upper and lower corrugating rollers is 48CrMo, treated with medium frequency, and with surface ground and chromium plated with a hardness of more than HRC58;

3.The ascent and descent of the upper corrugating roller and pressure roller and the movement of the glue applicator are controlled pneumatically;

4.All bearings of the upper and lower corrugating rollers and pressure roller are lubricated with high-temperature lubricating grease;

5.The surfaces of glue roller, doctor roller, pre-heating roller, and other paper guide rollers, etc. are ground, polished, and plated with hard chromium;

6.The diameter of the glue roller is 254 mm and the glue roller unit can be laterally removed as a whole; the design of the glue roller seat is optimized;

7.The machine is installed with an automatic PLC glue adjustment system (the gap between the glue roller and the doctor roller can be automatically adjusted according to the machine speed); the production speed is measured by and the produced length is calculated by the machine;

8.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;

9.An independent drive box with tri-shaft transmission through a universal joint can insulate power vibration and oil immersion lubrication can reduce noise, so the operation stability is enhanced;

10.There is a face paper pre-heating roller and a conditioning steam injector for core paper installed in the machine; a paper guide roller is added between the conditioning steam injector and the upper corrugating roller to reduce the contact area between the core paper and the corrugating roller and thus to lengthen the service life of the corrugating roller;

11.The whole surface of the doctor roller is immersed into a small glue pan so as to effectively lengthen the service life of the doctor roller by dint of the self lubrication and temperature lowering functions of the glue; the glue pan is made of stainless steel;

12.An electric glue partition device is provided to give convenient and rapid paper width adjustment;

13.The lateral movement of related roll stands is controlled in an interlock manner through the main control cabinet;

14.Complete protection net shields are provided for power and operation parts to ensure personal safety.
