How do hot melt adhesive machines work? Briefly describe the working principle of the hot melt adhesive machine
The hot melt glue machine is composed of a hot melt heating system, a pressure system, and a spraying system, and its working principle follows the sequential cooperation process of these three systems. Heating System The hot melt heating system converts electrical energy into thermal energy through an electric heating device and uses a high-precision PLC intelligent temperature control system to achieve precise temperature control. This system is mainly used to heat solid hot melt adhesive to a molten state. The inner wall of the glue tank is coated with Teflon , which can effectively prevent material carbonization, ensuring that the hot melt adhesive has good flow characteristics and reducing the risk of blockage. The precision of temperature control will directly affect the stability of adhesive viscosity and provide an important foundation for subsequent spraying or coating processes. Pressure System The pressure system generates stable pre...
