The driving mechanism 150 is used for driving the rolled piece 200 to lift back and forth along the vertical direction through the first guide 130, so that the rolled piece 200 moves up and down in the rolling mill body 120, the abrasion of the rolling mill body 120 when the rolled piece 200 is rolled is uniform, the service life of the rolling mill body 120 is prolonged, the condition of scratching the rolled piece 200 is avoided, and the quality of a rolled product is ensured.
It should be noted that, the second guide 140 is disposed above the first guide 130 and is fixedly connected with the rack 110, the first guide 130 and the second guide 140 are slidably matched along a vertical direction, and the first guide 130 can be close to or far away from the second guide 140 under the driving of the driving mechanism 150. Specifically, the first guide 130 and the second guide 140 together enclose a limiting cavity 170, and the limiting cavity 170 is used for limiting the rolled piece 200, so as to prevent the rolled piece 200 from being outwards shifted, and ensure that the rolled piece 200 moves towards the direction penetrating into the rolling mill body 120.
