Hot melt adhesive coater - use and daily maintenance 1

1、 Safety Quan matters during installation of hot melt adhesive coater

1. When installing the hot melt adhesive coater, a correct and effective grounding wire must be connected. Any he equipment using high voltage electricity needs to have a grounding wire. When the grounding wire is not used, the components with insulator protection on the Ren He hot melt adhesive coater may still form a voltage conductor and have the risk of electric shock. 2. According to the load required by the hot melt adhesive coater and its auxiliary peripheral equipment, check whether the used power line and insulation protection meet the regulations, and the load of the conductor must be higher than the rated power of the hot melt adhesive coater. 3. Ensure that the external voltage connected to the hot melt adhesive coater conforms to the hot melt adhesive coater itself. For example, the hot melt adhesive coater equipment with single-phase 220V voltage standard will damage the spraying equipment of the hot melt adhesive coater if 380V power supply is used. For example, the hot melt adhesive coater equipment with single-phase 220V voltage standard cannot meet the design performance of the equipment if power supply lower than 220V is used, It may also damage the hot melt adhesive coater. When wiring, ensure that its power line is correctly connected to the position of the external circuit breaker. 4. Ensure that the hot melt adhesive coater operates under the specified voltage. If the voltage used is different from that specified, the hot melt adhesive coater may be burned.

2、 Safety Quan matters during daily operation of hot melt coater

1. Avoid operating the hot melt adhesive coater around volatile and explosive raw materials or gases. Inflammables and explosives shall not be stored around the spraying equipment of the hot melt adhesive coater. 2. Do not operate the hot melt adhesive coater without proper protection device, good insulator or good protection panel. When maintenance is required, only specially Ye trained personnel can dismantle the coater for maintenance. 3. Do not operate the hot melt adhesive coater in the surrounding environment where the temperature is lower than 0 ℃ and higher than 50 ℃. 4. Try to use it when there is no fast flowing air. Because when the hot melt adhesive nozzle combination is exposed to the rapidly circulating air, the rapid cooling will affect the hot melt adhesive flow of the nozzle combination, which is easy to produce wire drawing phenomenon.

5. When adding hot melt adhesive, it should be added before Zui less than one third of the hot melt adhesive in the hot melt adhesive pot, so as to avoid adding adhesive when there is no hot melt adhesive in the hot melt adhesive pot, which will affect the normal production. 7. The amount of supplementary glue shall not exceed 80% of the total volume of the hot-melt glue pot.
