The operation steps of the laminating machine usually include the following links
First, the preparation stage
Check the machine: Before operation, it is necessary to check in detail whether the parts of the laminating machine are normal, including power supply, hardware, lubrication system, etc., to ensure that there is no damage or abnormal. If there is a difference, should be timely contact maintenance personnel for maintenance.
Lubrication and cleaning before starting: routine inspection and lubrication before starting, cleaning the dust and debris on the surface and inside of the machine, etc., to ensure that the machine is in good working condition.
Second, preheating and material preparation
Turn on the power and preheat: turn on the power supply of the laminating machine, and turn on the heating switch such as the laminating wheel and the drying wheel to preheat. The preheating time is generally 5 to 10 minutes, depending on the machine model and process requirements. When preheating, set the temperature control to the temperature suitable for the process requirements.
Prepare the material: according to the nature and size of the material to be coated, prepare the corresponding coating glue, film and film and other materials. At the same time, the necessary cleaning treatment is carried out on the items that need to be covered to ensure the film effect.
3. Adjustment and setting
Arrange paper or articles: Stack the paper or articles to be coated neatly and place them in the feed roller of the laminator. Ensure that the paper or articles can pass through the various parts of the laminating machine.
Adjust the pull gauge: loosen the fastening screw of the pull gauge frame, adjust the position of the pull gauge according to the size and shape of the item to be coated, and ensure that the film and the print are just combined. After adjustment, tighten.
Select the appropriate film and film: according to the size of the film to be coated, select the appropriate size of the film, and install it on the appropriate position of the air shaft to fix.
Film threading and adjusting: According to the film threading mark, pass the film on the air shaft through the tube wheel, expansion wheel, bending wheel, drying wheel, laminating wheel and other parts, and wrap around the winding air shaft. After the film is worn, the tightness of the film needs to be adjusted to make its surface flat. It can be adjusted by leveling mechanism (such as pipe wheel, air shaft, etc.) and components such as expansion wheel and bending wheel.
Four, film operation
Gluing: Using the ceramic wheel gluing system, the glue is evenly coated on the film. The amount of glue should be adjusted according to the quality requirements of the paper or article.
Laminating and drying: start the laminating machine, the film is coated by the coating wheel, and then dried by the drying wheel and drying oven. At the same time, the paper or articles to be coated are sent by Feida, and after being pulled flat to remove powder, the film is fitted under the pressure of the fitting wheel and the rubber wheel.
5. Paper receiving and follow-up treatment
Paper cutting and receiving: Through the chain knife automatic slitting paper system and the pan knife cutting notch speed difference pulling paper system, the paper or articles after the film is cut and received.
Inspection and cleaning: The items after the film need to be inspected to ensure that the quality of the film meets the requirements. At the same time, the plastic chips on the film plate are removed to avoid affecting the next use.
Power off and maintenance: After the operation is complete, turn off the laminating machine power, and discharge the exhaust gas and waste liquid. Perform necessary cleaning and maintenance on the laminating machine to extend its service life.
These are the basic operation steps of the laminating machine. In actual operation, there may be slight differences due to factors such as machine model and process requirements.
