The use of Coating Machine
Composite machine for shoe materials, electronics industry, sponge, EVA, PE, cloth and other plastic.
Coating machine。Tension system
1, process requirements
Coating machine need to glue or ink substances evenly adhere to the aluminum foil, plastic film or fabric textile surface, the coating process requirements are relatively high, not only requires a high degree of uniform coating and to be able to achieve high-speed non-stop change to improve production efficiency.
2, the program advantages
By the frequency converter to complete the tension control at all levels, the use of tension sensors to achieve tension control, the system is simple and stable. Use the PLC or the synchronization controller to control the speed of the drive roller and the line speed signal as the other frequency converter.
S350 closed-loop tension control (sense of vector control) easy to achieve acceleration and deceleration in the process of constant tension, saving installation tension
Roller space, reduce the cost of machinery, while high-precision control to ensure a high degree of uniform coating effect.
Double-position retractable roll with pre-drive function, to meet the high-speed non-stop automatic roll change, improve production
What are the precautions for the use of the coating machine?
3) set the coating work and related parameters (coating speed, length, gap length, roll ratio, etc.), and then connected to the compressed air (adjust the pneumatic control box pressure regulator to the pneumatic pressure of 0.2 ~ 0.3Mpa between);
4) Start the dry fan and dry the temperature controller.
5) Turn on automatic correction and tension controller power supply.
6) the temperature of each section of the equipment have reached the required temperature;
7) to the coating device hopper feeding, while starting the coating machine, for coating.
1.3 Shutdown procedures
1) Confirm that the coated pole piece has been wound and then stopped.
2) turn off the equipment heater power, until the temperature dropped to 60 degrees Celsius below, stop the drying fan and other fans;
3) Stop the compressed air.
4) Disconnect the power supply from the cabinet and the control cabinet.
1) the operator must undergo pre-job training and qualified by the assessment before induction, and should strictly abide by the operating procedures.
2) In addition to the necessary maintenance personnel, the non-authorized personnel to operate the device or change the setting parameters.
3) The roll ratio is set in the range of 1.3 to 1.5.
4) Make sure that the dry fan has been activated before starting the air heater.
5) When adjusting the gap between the coating roller and the back roller, the slurry on the coating roller should be wiped off and the back roller is not jammed. It is necessary to ensure that the rollers are parallel and the gap is uniform (there must be a gap).
6) After resetting the parameters, be sure to press the Insert button to change the parameters.
7) immediately after the shutdown of each class with alcohol or acetone cleaning hopper, scraper, coating roller and roller, the surface shall not be scratched and damaged.
8) Keep the back roller cylinder and straight rails clean and lubricated.
9) machine bearing parts to be regularly lubricated, the gear box to be regularly replaced or added.
10) in the process of running the problem must be immediately recorded and notify the relevant departments in order to deal with in a timely manner.
11) always do the equipment 5S work, to maintain equipment and the surrounding environment clean and tidy.
This procedure is only applicable to ST350-III type pole piece coating machine.
Coating process Operating procedures Process requirements:
1) the first coating length deviation ≤ 1mm, coating gap deviation ≤ 1mm.
2) the second side and the first side of the maximum dislocation ≤ 0.5mm.
