1¡¢Overview of laminating machine
Through the PE particles in the extruder inside the melt heated into melt, after the extruder die outflow, through the substrate appearance when condensation heat pressure, the two layers of information combined together to improve the tensile strength of the substrate, airtightness and moisture resistance of the plastic machinery and equipment, the profession is also known as extrusion compound machine, cast machine, extrusion cast machine, cast compound machine, film coating machine, etc.
2¡¢Laminating machine career use
(1) food: noodle strapping, ice cream packaging, milk powder packaging, tea packaging, melon bags, bread bags.
(2) Wooden products: tongue depressor packaging, ice spoon packaging, toothpick packaging.
(3) Paper: copper plate paper packaging, lightly coated paper packaging, copy paper (neutral paper).
(4) Life category: wet wipes bags, salt packaging, paper cups and papers.
(5) pharmaceutical packaging: medical device packaging, Chinese medicine packaging, pesticide packaging, veterinary packaging.
(6) other categories: test machine paper, aviation bags, bearing packaging, stainless steel information packaging, disposable travel supplies.
3¡¢Working principle
Film laminating machine process: put on the roll - preheating - corona - film lamination - cooling - cutting edge - winding up to improve the fastness of the combination with polar ink.
Film lamination: the molten plastic is extruded under the effect of the screw through the fixed shape of the extrusion outlet, the extruder screw host selects the ES580 vector control inverter, the controller according to the set film thickness, material width and material line speed automatically accounting for the screw host frequency.
Cooling: cooling the material to facilitate the next process. The cooling wheel uses ES580 open-loop vector control inverter, and the frequency is given directly by the controller according to the line speed.
Cutting edge:
(1) Remove the unprocessed part of the edge of the material
(2) Cutting edge speed and system line speed synchronization
Winding: the winding part uses the appearance of winding, driven by the drive roller to roll the winding roller, no need to account for the diameter of the roll. Drive rollers use ES580 open-loop vector control frequency converter, to A + B way to give speed, A frequency by the controller based on the line speed to give, B frequency through the tension swing reaction value for PID accounting to give (to get a higher response speed, can use ES850 to do closed-loop vector control).
4, laminating machine frequency control skills demand
(1) start and stop smoothly, the whole machine running line speed stable without fluctuations;
(2) closed-loop vector control with high accuracy of speed stability and fast response;
(3) support speed and torque control mode, torque control stability;
(4) low frequency large torque, control of permanent magnet synchronous motor start without rotation.
