Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt instruments, in particular to a hot-melt adhesive machine. Background Art

[0002] As a device widely used in industrial fields such as packaging, assembly, and other operations requiring bonding, the basic working principle of a hot-melt adhesive machine is to melt solid hot-melt adhesive into a liquid state through a heating device, and then transport the liquid hot-melt adhesive to the application position for bonding. Most of the existing hot-melt adhesive machines on the market mainly rely on gravity or simple mechanical structures to control the flow rate of the molten colloid.
