This invention relates to a kind of heat insulating layer air discharging structure for fridge. It includes the inner casing forming certain storage space; the foaming liquid is infected between inner casing and outer casing to form heat insulating layer; the air discharging hole which discharges the air between inner casing and outer casing in the process of injecting foaming liquid; the blocking component which selectively discharges the air between inner casing and outer casing through air discharging hole in the process of forming heat insulating layer; the screen cover that screens the air discharging hole when injecting the foaming liquid. This invention can prevent inner casing deforming when foaming liquid injecting and solidifying.

The invention belongs to the technical field of a conveyer device, and relates to a roll cloth loading conveyor which has the technical proposal that a front bracket and a rear bracket are arranged along the vertical direction; an inclined bracket is connected between the upper ends of the front and the rear brackets; transmission shafts are respectively arranged at the upper end of the rear bracket and the lower end of the inclined bracket; the two ends of the transmission shafts are respectively provided with sprocket wheels, and the sprocket wheels arranged at the same side of the transmission shafts are respectively hung with a ring-shaped chain; material plates are articulated on the outer surface of the ring-shaped chains at intervals, and the ring-shaped chains are parallel to the transmission shafts; the transmission shaft on the rear bracket is provided with a driving wheel in a coaxial way, and the driving wheel is driven by a motor and a transmission device; the outer inclined plane of the inclined bracket arranged between the two transmission shafts is evenly distributed with pin rollers that are parallel to the transmission shafts and used for supporting the ring-shaped chains. The roll cloth loading conveyor has the advantages of being time-saving and labor-saving, high in conveying efficiency, and capable of conveying the roll cloth into a truck in a good condition.
