[0002] The continuous casting machine drive roller (or continuous casting machine drive drum) is an important component of the continuous casting production line. It is mainly used to pull the billet and ensure that the billet maintains stable stretching and movement during the solidification process by transmitting power and controlling speed.

[0003] Specifically, during the continuous casting process, the molten metal is injected from the furnace into the mold and gradually solidifies into a cast billet. The drive roller system of the continuous casting machine contacts the surface of the billet and provides traction, so that the billet passes smoothly through the cooling zone, dividing zone and forming zone along the continuous casting line. The drive roller mainly performs the following key tasks: Pulling the billet: The drive roller system transmits external power to the billet, pushing the billet out from the inside of the casting machine; Control the billet speed: The speed of the driving roller controls the billet speed, ensuring the uniformity of stretching during the casting process and avoiding billet defects caused by uneven speed; Ensure a stable stretching process: the drive roller can maintain good contact with the surface of the billet to prevent the billet from breaking or deforming due to insufficient or excessive friction; Adjust the surface condition of the ingot: Appropriate roll pressure and rotation speed help to keep the surface of the ingot flat and smooth, reducing the occurrence of surface defects.

[0032] A servo motor 89 is fixedly installed inside the V-shaped seat assembly 21, the output end of the servo motor 89 is fixedly connected to the main shaft 86, the driving bevel gear 87 is fixedly sleeved on the outer periphery of the main shaft 86, one end of the synchronous screw 81 is fixedly connected to the driven bevel gear 88, and the driving bevel gear 87 is meshed and connected with the driven bevel gear 88.

[0033] The lifting cylinder 9 includes a contact roller 91 and a lifting seat 92. The lifting seats 92 are arranged on both sides of the contact roller 91 and are fixedly connected to the contact roller 91. The lifting seat 92 is transmission-connected to the mounting frame 3 through a ball screw nut pair.

[0035] The conveying device also includes support rollers 5, which are arranged at both ends of the conveyor belt 1 and are movably connected to the conveyor belt 1. Both ends of the support rollers 5 are rotatably connected to the fixed frame 31, one group of support rollers 5 is used to tension the upper part of the conveyor belt 1, and the other group of support rollers 5 is used to tension the lower part of the support rollers 5, thereby reducing the probability of slipping when the power roller 4 and the conveyor belt 1 are moving.

[0038] The working principle of the present invention is: first, the driving roller is placed on the conveyor belt 1, and then the conveyor belt 1 is driven by the power roller 4 to move, and the conveyor belt 1 then drives the driving roller thereon to move. However, the driving roller often has a large weight, which causes the conveyor belt 1 to be easily bent, and then the conveyor belt 1 cannot successfully transport the driving roller. Therefore, the synchronous lifting head 85 near both sides of the driving roller is controlled to move so that the synchronous lifting head 85 can tension the local conveyor belt 1 and the driving roller. At this time, the conveyor belt in contact with the driving roller can transmit the movement of the driving roller. This is a single stroke.

[0039] Next, the driving roller will be acted upon by the synchronous lifting head 85 and transferred to the next area of ​​the conveyor belt 1, and the driving roller will be transported again according to the above operation until multiple synchronous lifting heads 85 perform continuous activities of wave-like pushing transportation operations to transfer the driving roller.

[0040] In order to compensate for the insufficient movement or excessive stroke of the synchronous lifting head 85, the lifting seat 92 can be moved upward or downward at the same time to tighten or loosen the conveyor belt 1 to avoid the conveyor belt 1 slipping or the driving roller falling out, thereby realizing the continuous transportation operation of the driving roller.

[0041] In addition, since the support rollers 5 are arranged at both ends of the conveyor belt 1 and are movably connected to the conveyor belt 1, both ends of the support rollers 5 are rotatably connected to the fixed frame 31, one group of support rollers 5 is used to tension the upper part of the conveyor belt 1, and the other group of support rollers 5 is used to tension the lower part of the support rollers 5, thereby reducing the probability of slipping when the power roller 4 and the conveyor belt 1 are moving.
