What is the working principle of hot melt adhesive dispensing equipment?

图片
  The working principle of hot melt glue dispenser mainly includes four core steps: heating and melting, pressure delivery, precise coating and cooling and curing. The following is a detailed description:   1. Heating and melting ● Solid glue conversion: Add solid hot melt glue (glue strips, glue particles or glue blocks) to a heating device (such as a glue tank or a melt tank), and heat it to a molten state through an electric heating element (such as a PID temperature control system) (usually the temperature range is 120℃~180℃, depending on the glue type). ● Temperature control: Equipped with a high-precision temperature control system to ensure stable fluidity of the glue liquid and avoid carbonization or deterioration. Some equipment supports segmented heating or oil bath insulation treatment (such as EVA glue needs to avoid open flame heating).   2. Pressure delivery ● Pressurized extrusion: The molten glue is pressurized by a gear pump, piston pump or air pressure ...
