spanish Electronic grade protective film coating machine

Functional features of the whole machine

1. The unwinding adopts active unwinding, equipped with automatic film cutting device, automatically cutting the material thickness range (12~100μm), and equipped with a closed-loop constant tension control system to maintain stable material tension, reliable operation, taper tension control, and controllable accuracy. High; equipped with automatic edge correction device;

2. Before coating the substrate, a special explosion-proof ion rod static eliminator is installed to ensure the safety and explosion-proof of the coating head; before coating, a double-sided contact dust removal device is installed to ensure the surface cleanliness of the coating material;

3. Main coating process: Micro-concave reverse coating and slit extrusion coating are used, which are suitable for quantitative glue application;

 4. The oven adopts a clamshell structure, which is safe and easy to clean, has good sealing performance, and is designed with no dead corners inside the oven;

5. The interior of the oven, air supply ducts, circulation fans and other parts that come into contact with hot air are all made of stainless steel;

 6. The first three sections of the oven adopt hot air inlet from the top, exhaust from the bottom, and no return air design; the oven in the rear section adopts the hot air from the top, exhaust from the bottom, circulating air design; external heating method. The 1~3# oven belongs to the solvent volatilization section, with a reserved concentration detection and alarm device detection hole; the oven fan stops alarm and fault display functions to facilitate maintenance;

7. Traction, unwinding, cooling, traction and rewinding are made of a whole set of steel plates to improve its strength and precision. The independent structure ensures the smooth operation of the whole machine;

8. Double-station closed-loop constant tension taper control center winding machine to maintain balanced winding tension. It is equipped with a pressure roller and an approach roller device to ensure the flatness of the winding end face; the unwinding shaft and the winding shaft are interchangeable;

9. The air inlet duct and exhaust duct adopt temperature-resistant soft joints to effectively prevent fan vibration from being transmitted to the oven operating materials;

10. Large square tube door-width rack design, with an effective height of 2.6 meters below the rack, which is convenient for setting up dust-free compartments and making full use of the space below the rack;

11. Double-frame design, air supply and exhaust ducts adopt temperature-resistant soft joints to effectively prevent fan vibration from being transmitted to the oven operating materials

12. The oven adopts a clamshell structure and is equipped with a high-temperature high-efficiency air filtration (H14) system, which is safe and easy to clean. It has good sealing and ensures that the air entering the oven is clean and dust-free. The filtration efficiency is 99%, reaching the thousand-level dust-free standard;

13. Tension control of the whole machine: PLC centralized control, touch screen control and monitoring of the working status of the whole machine, integrated design of machinery, electricity and gas, with complete safety protection functions, capable of intelligently identifying the working status of the whole machine and judging faults

14. The main transmission bearings of the whole machine are made of Japanese NSK brand or equivalent brands;

15. The surfaces of all transition aluminum rollers are hard-oxidized, and the diameter of the bearings at both ends is 17mm; the diameter of the oven roller bearings is 35mm;

All transition rollers are balanced with a partial weight of less than 5g to ensure flexible operation;

16. There are pull rope emergency stop switches in the pressing parts (traction, lamination, material storage);

17. The main transmission motor of the whole machine adopts Siemens Beide variable frequency motor + Japanese Koyo encoder, and the transmission synchronization is precise;

18. The program control adopts Siemens system, with Ethernet communication interface, which facilitates subsequent data reading to achieve digital management;
