The invention relates to a system used for manufacturing an aluminum plastic composite belt with adhesive layers of continuous distribution and provided with a channel. The aluminum plastic composite belt is formed by bonding the adhesive layers between an aluminum foil layer and a plastic film layer. The adhesive layers are distributed between the aluminum foil layer and the plastic film layer continuously. The system comprises an aluminum foil layer discharging device, a plastic film layer discharging device, a composite belt forming device, a drying device, a composite belt traction device and a composite belt winding device. The composite belt forming device comprises a working platform, a plastic film layer rolling device, an adhesive layer spraying device, a composite belt forming device and an adhesive supply device. The channel for adhesive to pass through is formed in the bottom of an adhesive storing device of the adhesive layer spraying device and penetrates through the whole length direction of the bottom of the adhesive storing device. Pressure of the pressure supply source connected with a pressure transmitting device of the adhesive supply device is formed by gas. The gas is nitrogen or inert gas. The system is simple in structure, low in cost and easy to maintain.
