CE Certification HSY-120 Full-auto High Speed Varnishing & Calendering Machine Product, Products

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.

Varnishing & Coating System

Varnishing Machine Coating Unit

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.

Feeding & Heating Dryer System

Feeding and Dryer Unit

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.

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.

Conveying & Calendering Technology

Calendering Belt Conveying System
  • 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.

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).

Drying Tunnel & Stacking Unit

Drying Tunnel

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.

Paper Stacker Board

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.

Frequently Asked Questions (FAQ)

Q1: What heating system is used in the HSY-120 model?

The HSY-120 features an advanced electromagnetic heating system paired with internal quartz tubes, which optimizes heating efficiency while significantly saving electricity.

Q2: What is the maximum working speed and paper range supported?

The machine operates at speeds ranging from 25 to 80 meters per minute. It supports paper thickness between 200–800 g/㎡ and paper sizes from 350x400 mm up to 1200x1200 mm.

Q3: How many operators are required to run the High Speed Varnishing & Calendering Machine?

Only 1-2 operators are required to run the machine efficiently at maximum speed (80 m/min), reducing labor costs compared to manual machines which require up to 3 operators for lower speeds.

Q4: How does the electric heating dryer function?

The dryer utilizes 15 pieces of 1.5kw IR lights divided into two independently operated groups (9 pieces and 6 pieces). Coupled with air guiding boards and high-speed Teflon mesh belts, it ensures uniform and rapid drying during high-speed paper conveying.

Q5: How does HSY-120 handle automatic paper stacking?

Unlike manual machines, the HSY-120 includes a prolonged gap bridge board designed to synchronize with high-speed calendering operations, enabling smooth, full-page automatic paper stacking.

Q6: What structural improvements enhance the reliability of the coating unit?

The coating unit features a heightened/thickened wallboard, synchronous belts (replacing traditional chain drives to reduce noise), Teflon mesh belts for smoother transport, and worm gear scraper adjustments for easier maintenance.
