SJUV-760 Automatic Spot UV Coating Machine

SJUV-760 Automatic Spot UV Coating Machine

The automatic spot uv coating machine SJUV-760 is a new coating equipment with excellent performance, which integrates the advanced technologies at home and abroad. It can both local and overall coating, and has the advantages of high working speed, high gloss, thin and uniform coating layer. It is widely used in packaging decoration, book cover and other printing materials.

Product Parameter (Specification)

Product Feature And Application

The whole machine has a one-key acceleration function. After the main machine accelerates, the oven, paper delivery, feeder, and metering roller will all change according to the speed of the main machine.

1: Adopt high-speed offset press feeder to ensure fast and stable operation

2: Equipped with non-stop paper feeding device to ensure continuous production.

3: Use metering roller anilox roller to oil and then transfer to blanket.

4: The closed scraper is used to circulate the oil inside without outflow of oil, which can effectively reduce oil loss and volatilization.

5: Equipped with 18 IR lamps and 3 UV lamps, which are controlled separately.

6: Three roller design, tooth roller, plate roller, and anilox roller. Stable and durable, suitable for water-based, oily, blister oil, and uniform glazing effect.

Product Details

(1) Auto feeding

1: Adopt high-speed offset press feeder (12000 sheets/hour) to ensure fast and stable operation

2: Paper photoelectric control, automatic lifting

3: Double protection feeder lifting safety

4: Using the latest Pre-stacker design for Continuous paper feeding，greatly save paper time and reduce the labor intensity of operators.

(2) Coating section (basic oil coating head)

1: The anilox roller is used for oil supply, and the weight of oil is uniform. 80-120 mesh. You can choose different types of oil to achieve 3-10 grams of coating oil per square meter.

2: The closed scraper is used to circulate the oil inside without outflow of oil, which can effectively reduce oil loss and volatilization.

3: The main machine uses offset press to feed paper in its teeth, and paper of different thicknesses can work smoothly.

4: Photoelectric automatically control pressing to prevent oil on the back when there is no paper.

5: The plate roller is engraved with a network cable for easy alignment during plate pasting.

(3) IR Drying and UV Curing System

1: The length of the oven is 4300mm, which can effectively ensure the leveling and curing degree strength

2: Equipped with UV and IR systems, which are controlled separately and cannot be used at the same time.

3: 18 IR lamps and 3 UV lamps, IR lamps generally have a life of 2 years, UV lamps have a life of 800~1000H, and transformers have a life of more than one year .

4: The UV part adopts 8KW adjustable electronic light source, which has greatly improved safety performance than the traditional voltage source light source.The light source can adjust the brightness automatically as the change of machine's running speed, which can be changed from 30% to 100%. Thus the average energy consumption is saved by more than 30%.

5: Emergency stop or overheat protection device, when the emergency stop or the temperature inside exceeds 150 degrees, the protective cover will automatically rise to dissipate heat to prevent fire

6: Equipped with a ventilation system, under the UV curing box, there is a strong suction device composed of an exhaust fan and a wind box, which can extract ozone, dissipate heat and make the paper not easy to curl in the furnace, but can pass smoothly.

7: Equipped with automatic correction system, (double correction, double over-limit protection). The paper conveying adopts the imported Teflon conveyor belt, which can prevent ultraviolet rays, is strong and durable, does not support the paper, the electric eye detects the Teflon conveyor belt, and the automatic homing correction device

8: The whole process of suction to ensure that the coating products will not float and do not pile up paper. The oven is equipped with iron wire protection to prevent the paper from floating on the paper and cause a fire.

(4) Cooling system

After the paper dries out, it is quickly air-cooled to make the paper dry faster without anti-sticking.

(5) Automatic delivery system

1: Paper photoelectric control, automatic lifting

2: Double protection feeder lifting safety

3: Equipped with pneumatic paper flap function, you can set the number and time of the paper beat to ensure neatness

4: Disorderly paper automatic lowering function
