The unwinding adopts double stations to automatically change the roll without stopping, which has high production efficiency and can adapt to the requirements of different coating surfaces.
The slit extrusion die has high coating precision, and the coating error is less than 0.5 silk. The coating head and the dry glue detection are in the same system.
The oven adopts a large arc design, and there is no gap between the two. Sections 1-12 use top air supply. The hot exhaust gas is circulated into the air duct after being supplemented with fresh air, which greatly saves energy and reduces the emission of exhaust gas; the temperature control of the oven adopts a digital temperature control system, and SCR is used for adjustable power control, which reduces the impact on the power grid due to high-power electric heating. impact. According to the needs of the production process, it can be adjusted to low power operation, thereby greatly reducing energy consumption.
The adjustment mechanism of the squeegee for sizing the copper tape conductive adhesive. The scraper can be quickly adjusted up and down, back and forth, and the elevation angle, which improves the uniformity of the coating.
The laminating compound is manufactured by our company's "Chaos Mixing Energy-saving Extrusion Technology Patent" which has won the Science and Technology Progress Award. It has the characteristics of low energy consumption, excellent extrusion efficiency, good plasticizing effect and high production capacity.
Precise tension section control system makes the substrate run more smoothly. Reduce staff configuration (3-4 people can be used for the whole machine).
Touch panel is cleat and easy for operation.
Two motors control two rolls which makes power stable and rotation more smooth.
Electrical parts are from Germany Siemens, more stable.
Sheet processed by full auto programmable control, separation distance ±1mm.
Unwind part and rewind part are in the two sides of machines.
Hydraulic cylinder is imported from UAS, high-precision hydraulic station, pressure is stalbe.
EPC system for both unwind and rewind part, keep material straight.
Main rolls are made of special steel, high hardness, high pressure tolerance.
