[0037] The drainage module 2 includes a guide groove 201 for guiding the flow of aluminum liquid. The guide groove 201 is connected to the liquid outlet of the external insulation furnace. After the aluminum liquid passes through the insulation furnace, it is transported through the guide groove 201.

[0038] The composite hot rolling module 1 comprises a hot rolling base 11, on which a rolling channel with a variable pitch is provided. The copper strip is introduced into the rolling channel, and the aluminum liquid is injected into the rolling channel to contact the copper strip. The aluminum liquid is cooled in the rolling channel and combined with the copper strip to form a composite strip. The thickness of the composite strip is controlled by adjusting the pitch of the rolling channel.

[0039] An adjustment mechanism is fixed to one end of the hot rolling base 11 facing the drainage module 2. The adjustment mechanism has a mobile platform that can move with multiple degrees of freedom. A casting nozzle 12 is fixed on the mobile platform. One end of the casting nozzle 12 is connected to the guide groove 201, and the other end of the casting nozzle 12 is connected to the rolling channel. The mobile platform with multiple degrees of freedom can accurately control the movement of the casting nozzle 12 to ensure the flow and distribution of the aluminum liquid, so that the aluminum liquid evenly covers the copper strip, avoids uneven thickness, and can reduce defects such as pores and inclusions in the composite strip.

At the same time, the casting nozzle 12 that moves with multiple degrees of freedom can ensure the flow and distribution of the molten aluminum, so that the molten aluminum can evenly cover the copper strip, avoid uneven thickness, and reduce defects such as pores and inclusions in the composite strip. In addition, by adding a heat preservation component to the auxiliary material unwinding module 3, the heat loss of the auxiliary material is reduced, the temperature of the auxiliary material is maintained, and the scrapping of the auxiliary material due to humidity and temperature is avoided.

[0043] In an optional example, in order to reduce the structural volume of the auxiliary material unwinding module 3, please refer to Figures 1 to 3 As shown, the expansion clamping mechanism 33 includes an expansion and telescopic cylinder 37 fixedly connected to the rotating platform 32 by bolt connection, the expansion and telescopic cylinder 37 is arranged along the rotation center line of the rotating platform 32, and the expansion and telescopic cylinder 37 is provided with a movable telescopic end 371 at one end away from the rotating platform 32, and the telescopic end 371 is drivingly connected to the expansion clamping end 35 and the heat preservation end 36, and is used for controlling the movement.

[0049] Specifically, in this example, by adding a heat insulation layer 38, there is no direct contact between the expansion block 352 and the auxiliary material coil, and the heat cannot be directly transferred to the clamping assembly, thereby avoiding heat accumulation in the clamping follower assembly 353 and improving the service life of the clamping follower assembly 353. In addition, through the cooperation of the driven cooling channel and the clamping connection cooling channel 3541, the coolant can circulate in the system to further take away excess heat, ensuring that the clamping follower assembly 353 operates at a lower temperature, thereby improving the reliability of the equipment, extending the service life of key components, and reducing maintenance costs.

[0062] Step 1: Accurately take each component of the aluminum matrix material according to the formula and place it in a melting furnace to melt it into liquid aluminum alloy;

[0063] Step 2: Heat the composite auxiliary material to 210-250° C. and place it on the auxiliary material unwinding module 3. The composite auxiliary material passes through the composite hot rolling module 1 in the form of a strip and is connected to the winding module 4.
