Gluing and cleaning method of PUR hot melt adhesive laminating machine

The PUR hot-melt adhesive coating laminating machine uses 100% solid hot-melt adhesive that does not contain harmful ingredients. After being heated into a liquid state, it is uniformly and regularly coated on the surface of the work to achieve the purpose of adhesion. . According to different processing objects, different coating forms such as dispensing, spraying and rolling, and fiber coating can be selected respectively. Due to the simple operation of the equipment, reliable and fast bonding, high processing efficiency, uniform coating consumption, low glue consumption, no pollution to the environment, and compliance with current environmental protection requirements, it has been used for shoemaking, packaging, leather goods, paper boxes, accessories, and building materials. , Sports equipment, sanitary products, toys, electronics, electrical appliances, leather, furniture and other industries are increasingly selected as supporting production equipment.

Cleaning method Coating knife head cleaning: After the equipment is heated, wipe it with dry gauze.

Roller cleaning: wipe the stainless steel roller with clean dry gauze dipped in 75% alcohol, if there is glue on the surface, use dry gauze dipped in 1620 solvent/ethyl acetate solvent to wipe;

The glue on the surface of the rubber roller must not be treated with organic solvents, so as not to damage the rubber roller, it should be removed with a strong curing adhesive.
The outer surface of the equipment; cleaning method: use a clean dry gauze dipped in 75% alcohol to wipe.
Change batch cleaning: Clean the glue box and hose of PUR hot melt adhesive coating laminating machine (applicable to changing glue model and coating method): After emptying the original glue, add the new glue 2~3Kg, and heat it until it is completely melted. Empty, then add a new type of glue, after completely melted, drain at least 1Kg to start formal production.

Coating knife head cleaning (applicable to changing glue model and coating method): After the equipment is heated, use dry gauze to wipe.

Roller in the coating compound position: Use clean dry gauze to wipe the dust on the surface. If glue is found on the surface, do not use organic solvents to avoid damage to the rubber roller. Use a strong curing adhesive to remove it.

Cleaning the corona device: After confirming that the power is turned off, wipe it with a clean dry gauze dipped in 75% alcohol.

Non-fixed cycle cleaning of PUR hot melt adhesive coating laminating machine: the coating head of PUR hot melt adhesive coating laminating machine must be cleaned when the coating method and glue category level change, and the coating head must be removed before the glue is solidified. , Use dry gauze dipped in solvent to wipe the head clean. When the equipment is shut down during the production process, the overflow glue must be wiped off with clean gauze when the equipment is turned on. Clean the filter screen of the PUR hot melt adhesive coating and laminating machine for half a month. Cleaning the filter screen of the coating head of the PUR hot melt adhesive coating laminating machine.

Production has been suspended for more than one month, and all coating equipment must be cleaned according to the contents and requirements of the above daily, before and after batch change, half a month and non-fixed cycle cleaning before being put into use; for PUR hot melt adhesive coating laminating machine glue After emptying the original glue, add about 30Kg of white mineral oil to dissolve the residual glue. After emptying, add about 30Kg of white mineral oil to dissolve it again, and wait for it to be used after being completely emptied.
