Product Description High-speed NCR Paper Coating Machine LineProduct DescriptionStable tension control is to ensure the normal operation of the equipment, due to the high speed of the machine, the low quantitative base paper, the machine speed chain is from the SIEMENS PLC and module to achieve automatic, closed-loop, digital control, with the rotary encoder, proximity switch and the tension sensor, it can achieve high-precision closed-loop control; tension control accuracy is of 0.5kg or less to reduce the probability of paper breaking during the production process and improve productivity and yield. Detailed PhotosThe unwinding unit consists of a stand, pneumatic shaft and tension sensor, tension controller, and pneumatic brakes and these also constitute a tension automatic control system.The rack is equipped with an adjustable frame, the position of the base paper can adjusted in coating machine.Through the PLC, it can get constant tension, automatic control, and adjustable tension. Air knife coater is mainly composed by the eagle beak knife, feeding roll, pressing roll, metering rod, backing roll, air separator, draft fan for separator, high-pressure fan and frame, etc.This coating device is characterized by a short distance between the air knife backing roll and the feeding roll, and the coated paper is less water migrated and wrinkled after the metering rod. It has the advantages of a compact structure, wide application range, convenience to adjust the coating weight, and so on.Air knife (eagle beak type) Composed of the up and bottom lip plates, air knife body, air distribution tube. Up and bottom lips are made of 304 stainless steel, through multiple precision processing. The shape of the air knife blade can make high-speed airflow along the breast roll tangent direction, with the merit of good quality coating, less spray, and so on.Air knife adjustmentThe knife gap can be adjusted between 0.3-1.0mm. The air gap between the knife and the backing roll and angle can be adjusted by adjusting the frame, and air pressure can be adjusted to control the coating weight.Air knife backing roll During the coating process, the paper with excess coating color wraps around the backing roll, and the roll surface becomes the supporting surface for the paper to bear the airflow. The cooperation between the air flow and the air knife is used to meter the coating amount. Air knife backing roller Φ270mmx1400mm, roll body is seamless steel pipe, surface hard chrome plated.The feeding rollΦ216mmx1400, the roll made of seamless steel pipe, hard chrome plated treatment, with single drive of the three-phase asynchronous motor.Metering rod The metering rod device mainly plays the role of the pre-metering of coating amount, by scrap exceeding color on the paper to reduce the air knife metering burden and reduce the color splash. Metering rod diameter Φ50mm, chrome plated, with drive motor.Color tray The paint tray is made of stainless steel, there are two trays, a feeding roll tray, and a backing roll tray, respectively for storage and recovery of coating color.Air separator device Due to high speed and high wind pressure, in order to prevent the coating splash phenomenon, design the color splash recovery device. The power of the air-separating fan is 2.2Kw.High-pressure fan Select a special series of energy-saving coating fans, with a fan power 7.5Kw. The fan is characterized by high wind pressure, low noise, and wind pressure stable.The frameBox-type structure, welded, the coater is separated. CF drying and CB drying, 2 sets of oven boxes separately, mainly composed of oven box, fans, heat exchanger and air duct, etc.I choose the burners, the air stove is a direct-fired type, with no heat exchange equipment, and the system automatically controls the switch, gas and energy efficiency is high.
