Detailed Description

OPP film lamination is to keep the gloss of sheet surface, pull resistant and waterproof. It is often used to laminate portable paper bag, poster, book cover and catalog. OPP film and glue are expensive, the production speed is too slow and glue lamination cost is comparatively high, so our company uses mid –wave quartz lamp and highly efficient heat energy electro thermal heating to speed up the curing speed. The whole machine has ratio continuously running system and high speed inverter principle, worm wheel deceleration, gear wheel, synch-belt and chain transmission of each lamination roller to guarantee the same speed and improved lamination speed to lower the working cost and improve productivity. Standard equipments: Automatic stream feeder Suction head is controlled by rotary air valve of simple and reliable structure without maintenance for a long time. Scientific design of suckers and governing foot cam wheel can guarantee precise work and durable running. Sheet-forwarding suckers adopt high security straight-line guide rail. Sensitive mechanical and electrical double sheet detector will detect multi-sheet, no sheet or inclined sheet automatically. Max loading height:1050mm(41.3),with emergency stop and protection board against foreign objects. Coating unit Coating unit is of two-roller separate motor driving which can be running at high speed and can be controlled with main machine at same speed. Recycling glue supply system suitable for different glues. Meeting with emergency, OPP film will stop gluing. Before gluing, OPP film will be flattened by a flattening shaft to avoid OPP film looseness. wrinkle and inclination. Remaining OPP film auto reused device and film micro adjustment mechanism. Curing device Hot air supplied by the electric fans above the reflecting hood through six IR lamps and six electro thermal tubes, having even hot air distribution on the OPP film Hot air blown by front fans through six front radiating electro-thermal tubes can make even hot air distribution on OPP film and it can make glues dry in a short time. The impregnate inside the box can be exhausted through upper pipe extended outside. The heat-off device inside the curing box is used to guard against touching and ensure room time. The impregnate inside the box can be exhausted through upper pipe extended outside. The heat-off device inside the curing box is used to guard against touching and ensure room temperature. Aluminum guiding tube can be adjusted separately to make OPP film tense and horizontal. Laminating unit Before lamination, OPP film will go through twisted shaft to avoid film looseness, wrinkle and inclination. Laminating unit uses automatic temperature control electro thermal roller whose temperature is steady. Laminating pressure is adjusted by hydraulic cylinder (Japan make)and manual pump to get even pressure on left and right sides. Automatic cutter Round and rotary cutter whose speed can be micro adjusted. The speed of electronic system automatic adjustment cutter will be the same with main machine. There is a sheet rolling mechanism to roll the sheet continuously and separately on the cutter without the need to have extra space. Manual delivery table. Auto control Safe and dependable motor speed adjustment by inverter. PLC control provides easy operation and easy maintenance. OPTIONAL EQUIPMENTS： Automatic delivery： Mechanical double side sheet trimmer and forced sheet flattening and balancing device to avoid the inertial stroke when releasing thick sheet to ensure smooth and neat delivery. Emergency indication lamp and safety detection system can inform emergent conditions to operators. Non-stop mechanism for feeder and delivery: Semi auto auxiliary table for sheet feeding to pre-pile out of fedder,hight:900mm(35.4’’),to be pushed in by a dolly. When the delivery auxiliary table starts ,the main machine decrease automatically to improve production efficiency.
