[0002] Copper rod rolling mill is a kind of equipment used to produce copper rods, which is widely used in industries such as wire and cable, electrical equipment and machinery manufacturing.

[0003] The existing copper rod rolling mill adopts a double-shaft double-roller structure, in which one roll gear shaft is fixedly connected to the external transmission mechanism as the input gear shaft, and meshes with the other driven roll gear shaft to form a primary transmission gear mechanism. On the one hand, this transmission mechanism has poor transmission stability and low load-bearing capacity. On the other hand, when the roll size needs to be changed and the input gear shaft needs to be replaced, the roll gap needs to be adjusted by rotating the eccentric seat outside the driven roll shaft to adjust the spacing between the two rolls. The adjustment speed is slow, the adjustment range is small, and the operation of replacing the gear shaft is difficult.

[0004] In view of this, how to provide a copper rod rolling mill that can partially or completely solve the above problems is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0014] Furthermore, it also includes a box body, the input gear shaft, the lower gear shaft, the upper gear shaft, the first eccentric seat and the second eccentric seat are arranged in the box body, and the first adjusting screw rod and the second adjusting screw rod extend out of the box body.
