QUV-120 Coating Machine Part
  • ● The first coater is for effectively cleaning the printing powder
  • ● Base oil coater is for more even coating
  • ● Both coaters help to save UV oil’s consumption
A
Main transmission part, oil limiting roller and conveying belt are separately controlled by 3 convertors motor.
B
Papers are conveyed by imported Teflon net belt, which is ultraviolet-proof, sturdy and durable, and will not damage the papers.
C
Photocell eye senses Teflon net belt and automatically corrects deviation.
D
Machine’s UV oil solidification device is composed of three 9.6kw UV lights. Its overall cover will not leak UV light so that the solidification speed is very soon and the effect is very good.
E
Machine’s IR dryer is composed of twelve 1.5kw IR lights, which can dry oil-based solvent, water-based solvent, alcoholic solvent and blister varnish.
F
Machine’s UV oil leveling device is composed of three 1.5kw leveling lights, which can resolve UV oil’s stickiness, effectively remove product surface’s oil mark and smoothen and brighten the product.
G
Coating roller uses reserve-direction coating way; it is separately controlled by convertor motor, and via steel roller to control the oil coating amount.
H
Machine is equipped with two plastic cases in circular offering oil, one for varnish, and one for UV oil. UV oil’s plastic cases will automatically control the temperature; it has better effect when interlayer uses soya oil.
I
The rise & fall of UV light case is controlled by pneumatic device. When power is cut, or when conveying belt stops working, UV dryer will automatically lift up to prevent UV oil solidification device burn papers.
J
The strong suction device is composed of exhaust fan and air box which are under the UV oil solidification case. They can exhaust ozone and radiate the heat, so that paper will not be curl.
K
Digital display can automatically and accurately examine output of single batch.

Frequently Asked Questions (FAQ)
1. What paper size and thickness capabilities does the QUV-120 support?
The QUV-120 supports paper sizes ranging from a minimum of 350(W) x 400(L) mm up to a maximum of 1200(W) x 1200(L) mm. It handles paper thickness between 200 g/㎡ and 600 g/㎡.
2. What types of solvents can be dried using the machine's IR dryer?
The machine's IR dryer consists of twelve 1.5kw IR lights capable of effectively drying oil-based solvents, water-based solvents, alcoholic solvents, and blister varnish.
3. How does the QUV-120 protect paper from burning during power cuts or conveyor stops?
The UV light case features a pneumatic rise and fall control system. In case of a power outage or when the conveyor belt stops, the UV dryer automatically lifts up to prevent the solidification device from burning paper.
4. How does the machine handle ozone exhaust and heat dissipation?
It is equipped with a strong suction device consisting of an exhaust fan and an air box located underneath the UV oil solidification case. This setup efficiently exhausts ozone and radiates heat to prevent paper curling.
5. What features help optimize UV oil consumption and finish quality?
The QUV-120 utilizes a dual coater configuration—the first coater cleans printing powder while the base oil coater ensures even application. Combined with reverse-direction coating rollers, it significantly reduces UV oil consumption while producing a smoother, brighter result.
