HSY-120 Full-auto High Speed Varnishing & Calendering Machine

Short Description:

HSY-120 is an All-in-one Machine combines the paper finishing process of varnishing and calendering. Due to the increasing labor costs in China, we specifically develop a machine that connects a varnishing machine with a calendering machine; moreover, we automate it into a high speed one which can be operated by just one man.

With an automatic steel-belt-connector avoiding function, its maximum speed reach up to 80m/min! Compared with the traditional ones, its speed has been increased for about 50m/min. It helps printing & packaging companies to better improve their production & working efficiency.

ADVANTAGES

Enlarged steel roller (Φ600mm) & rubber roller diameter(Φ360mm)

Heightened machine height (feeding part can send maximally 1.2m high paper pile, increase efficiency)

Automatic belt avoiding function

Widen & extended dryer (increase working speed)

DETAILS

1. Automatic Paper Sheet Feeding Part

The feeding part’s height is raised to 1.2 meter, which prolongs 1/4 period of paper changeover. Paper pile can be 1.2 meters high. So that paper sheets can be easily delivered to the calendering machine right after they come from the printing machine.

2. Varnish Coating Part

By going through between the steel roller and rubber roller, paper sheets will be coated with a layer of varnish.
a. The wallboard of the coating part is heightened and thickened to be more matured and steady.
b. We replace the chain transmission structure with synchronous belts structure for a more stable operation state. It reduces noise, too.
c. Paper sheets are conveyed by Teflon mesh belts instead of the traditional rubber belts which help to raise the speed of the whole machine.
d. The overturn of scraper is adjusted by worm gear instead of screw which is easier in the cleaning of scraper.

3. Dryer

The electric heating dryer is composed of 15 pieces of 1.5kw IR lights, in two groups, one group has 9 pieces, one group has 6 pieces, working independently. It makes printing paper surface turn dried during the dryer. By the conveying of high speed running Teflon mesh belt, paper sheets can be delivered more stably without movement. In the dryer above the fans, there are air guiding boards that can lead the air to dry the paper effectively.

4. Automatic Connecting Plate

a. We use wide belt to convey paper sheets and it suitable for different sizes of sheets.
b. Under the belt there are air suction device which ensures the stable conveying of the sheets.

5. Calendering Part

Paper sheets will be calendered by a hot steel belt and go through the pressing between the belt and the rubber roller. As the varnish is sticky, it will keep paper sheets kind of slightly stick on the running belt without fall off in the middle; after cooling paper sheets will be easily took down from the belt. After calendered, paper will shine bright like a diamond.

We thicken the machine wallboard, and enlarge the steel roller, so during the high speed operation increase the heating between steel roller and steel belt. The oil cylinder of the rubber roller uses hydraulic motor in the calendering (other suppliers uses manual pump).

6. Drying Tunnel in the Calendering Part

Drying tunnel is widen and largen along with the enlarging of roller. The door open method is more humanized and is easy for viewing or adjustment.

7. Automatic Paper Stacker

It solves the problem that manual calendering machine cannot be equipped with automatic paper stacker and realize the full page paper stacking work.

In order to match up with the high speed running of calendering machine, we prolong the gap bridge board for convenient and fast paper stacking.
