A fully automatic hot melt adhesive machine control structure

Abstract

The utility model discloses a fully automatic hot melt adhesive machine control structure, which belongs to the technical field of hot melt adhesive machines, and includes a hot melt machine body, wherein a plurality of metering pumps are fixedly installed on the outer side of the hot melt machine body, and the output ends of the plurality of metering pumps are respectively fixedly connected with throats. In the utility model, by respectively arranging a rotating box and an auxiliary controller on the side of each spray gun, the auxiliary controller can be used to control the heating network and the metering pump separately when the staff holds the spray gun to apply glue, so as to avoid the need for the staff to walk to the hot melt machine body to adjust the parameters when the parameters need to be adjusted. At the same time, after the auxiliary controller controls the heating network and the metering pump separately, the temperature and flow rate of the spray gun glue can be adjusted separately, so that the temperature and flow rate of the hot melt adhesive sprayed by each spray gun are different, so as to adhere materials with different requirements, thereby improving the practicality of the fully automatic hot melt adhesive machine control structure.
