DETAILED DESCRIPTION

[0020] Embodiment 1

[0023] When the present embodiment is used, when the material is in the shape of a strip, the worker sequentially passes the material through the auxiliary conveying assembly and between the roller c22 and the lower pressing roller 191. During the conveying process, the lower pressing roller 191 will rise and fall according to the thickness of the material, and the spring b18 will allow the lower pressing roller 191 to always be in sliding contact with the upper end surface of the material during the lifting and lowering process of the lower pressing roller 191, so that the material can be conveyed stably and the friction between the material and the device can be reduced, thereby reducing the maintenance cost of the device. When the cross-section of the material is circular or rectangular, the worker sequentially passes the material through the auxiliary conveying assembly and between the two clamping tables 20, so that the two clamping tables 20 can be clamped.

[0024] Embodiment 2

[0025] like Figure 1-Figure 4As shown, the feeding device of a rolling mill proposed in this embodiment, compared with the first embodiment, in this embodiment, also includes a lifting plate 12, wheels 13, a motor b14, a screw b15 and a push rod 27, the motor b14 is arranged on the base frame 1, the screw b15 is vertically rotatably arranged on the base frame 1, the motor b14 is drivingly connected to the screw b15, the base frame 1 has a movable groove 101, the lifting plate 12 is slidingly arranged on the movable groove 101, the lifting plate 12 is drivingly connected to the screw b15, a plurality of wheels 13 are arranged at the bottom of the lifting plate 12, and the push rod 27 is arranged on the base frame 1.

[0026] In this embodiment, after the feeding device has conveyed all the materials, the worker can control the motor b14 to drive the screw rod b15 to rotate, and the screw rod b15 drives the lifting plate 12 to descend until the multiple wheels 13 are in contact with the ground. Then the worker pushes the push rod 27 to move the feeding device to a position where it will not hinder others.

When the material is conveyed in a bent direction, it is often difficult for the rolling mill to roll higher quality materials. The worker places the material on the device with the bending direction facing downward. When the material is conveyed to the auxiliary conveying component, the motor a3 drives the bevel gear a4 to rotate, and the bevel gear a4 drives the screw a6 to rotate through the bevel gear b5.
