The operating procedures of the hot melt coating machine are the key to ensuring the safe and efficient operation of the equipment. Following the operating procedures can ensure the safe and efficient operation of the hot melt coating machine. At the same time, it can also extend the service life of the equipment and improve the coating quality.

1、 Equipment preparation and inspection

Ensure equipment condition: Before operation, it is necessary to ensure that the hot melt coating machine is in good working condition and check whether all components are intact, including the heating system, coating head, control system, etc. If any abnormalities occur, the operation should be stopped immediately and repairs should be carried out.

Check supporting facilities: Ensure that power, gas, and other supporting facilities are functioning properly, and ensure the energy supply required for equipment operation.

Check the set parameters: Check whether the temperature control, pressure control, flow control and other parameters of the hot melt coating machine are normal. Generally, they do not need to be reset, but if necessary, they should be adjusted according to the equipment manual.

2、 Startup and Glue Addition

Start the device: Turn on the device power and start the hot melt coating machine. Turn the power switch to the ON position and wait for the temperature of all heating systems to reach the set temperature.

Add hot melt adhesive: Place clean and dry hot melt adhesive into the glue storage bin, quickly close the lid to prevent foreign objects from entering.

3、 Adjustment and coating

Connect the air source: Connect the air source to the quick connector of the electric needle valve nozzle combination and adjust the pressure to the desired value.

Adjust the coating head: Adjust the position of the coating head according to the coating requirements to ensure even coating.

Adjust coating parameters: Adjust coating speed and pressure as needed to ensure coating quality. During the coating process, it is necessary to closely observe the coating effect. If any abnormal situation occurs, the operation should be stopped immediately and the cause should be investigated.

4、 Shutdown and Cleaning

Turn off the device: After coating is completed, turn off the power supply of the hot melt coating machine and cut off the external power supply.

Cleaning the site: Clean the surface of the equipment and components such as the coating head filter screen to ensure the cleanliness and dryness of the equipment. Put the remaining hot melt adhesive back into the adhesive storage tank and close the lid of the tank.

5、 Safety precautions

Wear protective equipment: Operators should wear safety gloves, goggles, long sleeved work clothes and other protective equipment to avoid being burned by high-temperature liquid hot melt adhesive or high-temperature component surfaces.

Avoid touching high-temperature components: During equipment operation, do not touch high-temperature components such as nozzle assemblies to avoid burns.

Environmental requirements: Avoid operating equipment around volatile and explosive materials or gases, and avoid using it in environments with low or high temperatures. In addition, try to use it in areas without fast flowing air to prevent wire drawing.

Non professionals are not allowed to operate: Non professionals are not allowed to operate the hot melt coating machine at will to avoid safety accidents or equipment damage.

6、 Maintenance and upkeep

Regular inspection: Regularly inspect the wear and tear of various components of the equipment, including the heating system, coating head, control system, etc. If there is wear or damage, it should be replaced or repaired in a timely manner.

Cleaning equipment: Regularly clean the surface of the equipment and components such as coating heads and filters to ensure the cleanliness and dryness of the equipment. At the same time, clean up any foreign objects or residual hot melt adhesive that may exist inside the equipment.

Maintenance: Conduct regular maintenance according to the equipment manual, including replacing vulnerable parts, inspecting the electrical system, etc. Ensure long-term stable operation of the equipment.
