Precautions for installing and using the hot melt glue machine.
⒈ When installing the hot melt glue machine, a correct and effective grounding wire must be connected. Any equipment using high voltage electricity requires a grounding wire. When the grounding wire is not used, any component on the hot melt glue machine with insulator protection may still form a voltage conductor, causing the risk of electric shock.
⒉ According to the load required by the hot melt glue machine and its peripheral equipment, check whether the power cord used and the insulation protection meet the regulations. The load of the thermal melt glue machine line must be higher than the rated power of the hot melt glue machine.
⒊ Ensure that the voltage connected to the hot melt glue machine is consistent with the hot melt glue machine itself. For example, if the hot melt glue machine equipment with a single-phase 220v voltage standard uses a 380V power supply, the hot melt glue machine spraying equipment will be damaged. If the hot melt glue machine equipment with a single-phase 220v voltage standard uses a power supply lower than 220V, it cannot achieve the equipment design performance and may also damage the hot melt glue machine. When wiring, ensure that the power hot melt glue carbon cloth composite machine line is correctly connected to the external circuit breaker position.
⒋ Ensure that the hot melt glue machine operates at the specified voltage. If the voltage used is different from the specified voltage, the hot melt glue machine may be burned.
5. When operating the hot melt glue machine, do not place other debris on the machine body or use it as a cushioning device. Avoid operating the hot melt glue machine around volatile and explosive raw materials or gases. Do not store flammable and explosive items around the hot melt glue machine spraying equipment, hot melt glue guns.
The reflux valve device is very important in the hot melt glue machine system. Generally, it is rarely adjusted during use. Under normal circumstances, the hot melt glue machine manufacturer has adjusted it to the normal application pressure value before leaving the factory. The main function of the reflux valve device is to adjust the output pressure of the main engine of the hot melt glue machine. When the pressure value is large, the glue output is large, and when the pressure value is small, the glue output is relatively small. At the same time, it is also to protect the gear pump and the drive device to prevent the system from running under overpressure when the machine is shut down. Before adjusting the reflux valve, make sure that the hot melt glue machine, hot melt glue hose and hot melt glue gun are working at the set temperature, and then loosen the slotted screw on the reflux valve. Rotating it in reverse time is to reduce the pressure value, and rotating it in the forward time is to increase the pressure value. When increasing the pressure, remember not to lock the reflux valve to the bottom, otherwise it will be overloaded and cause the motor to burn or the gear pump to wear.
In short, there are many precautions for the use of hot melt glue machines. It is very important to choose a suitable hot melt glue machine for all users.
