Cleaning the drawdown blade coater is a key step to ensure efficient operation of the equipment and mass production. Below are detailed cleaning methods and recommendations based on what you have provided.
1. Measurement part cleaning: Measurement part should be cleaned immediately after each shutdown, especially the material scattered on the material plate to ensure that the parts are kept clean and avoid corrosion and affect the next production.
2. Heat seal body cleaning: In order to ensure that the sealing texture is clear, the heat seal body needs to be cleaned frequently to ensure its normal function.
3. Photoelectric tracking light head cleaning: regularly clean the electric eye to ensure accurate cursor tracking and avoid affecting the production mass due to small errors.
4. Electric control box cleaning: Regularly clean the dust in the electric control box to prevent the occurrence of electrical failures such as poor contact.
1. Spreader knife head cleaning: Use dry gauze to wipe the Spreader knife head after heating to ensure cleanliness and readiness.
2. Stainless steel roller and outer surface cleaning: Use dry gauze dipped in 75% alcohol to wipe the outer surface of stainless steel roller, corona device and equipment. If glue residue is found on the surface of stainless steel roller, use dry gauze dipped in 1620 solvent or ethyl acetate solvent to wipe to ensure thorough cleaning.
Regularly clean the roller, pay special attention to remove the cloth scraps, paper scraps or carbide that may be generated in the operation of the hot-melt adhesive coater. Raise the silicone wheel, run the roller slowly, and fine-tune the glue amount of the working object to make the debris pass through the gap smoothly.
1. Glue Tank and Spreader Roller Cleaning: Use ethyl acetate for deep cleaning. Pad 3-4 films in the glue tank, swirl/spin the Spreader roller slowly, apply the wash solution with a paint brush and let stand for 5-10 minutes. Brush the surface of the roller with a metal brush 2-3 times to ensure complete removal of residue. Finally use ethyl acetate and a fine copper wire brush for final cleaning until the roller is completely clean.
2. Cleaning cycle: Determine the cleaning Frequency according to the product Appearance and production volume. It is generally recommended to carry out a thorough cleaning every week or two weeks to ensure the stable operation of the equipment and the mass of the product. Through the above detailed cleaning steps and methods, the various components of the drawdown blade coater can be effectively protected, prolong the life of the equipment, improve the production efficiency, and ensure the safety of the product mass and operation. Regular cleaning and maintenance can not only reduce machine failure, but also improve the overall production efficiency and product conformity.
