Application construction process of hot melt adhesive on refrigerated container

The invention provides an application construction process of a hot melt adhesive on a refrigerated container. The application construction process comprises the following steps that the hot melt adhesive is added into a melting cylinder; grease on the surface of a refrigerated container plate is removed; the position of the plate relative to a hot melt adhesive spraying station is sensed; the hot melt adhesive in the melting cylinder is heated to the set temperature, the hot melt adhesive is dissolved, and a hot melt adhesive melting conveying channel is heated to the set temperature; when the set temperature is reached, a gear pump in the hot melt adhesive spraying station is started to convey the hot melt adhesive; the hot melt adhesive is filtered through a filter screen, the hot melt adhesive passing through the filter screen is conveyed to a throat pipe, and the hot melt adhesive not passing through the filter screen enters the gear pump again through a return valve on a pipeline; and the hot melt adhes
