Two sets of straightening rollers 220 are provided, and one end of each set of straightening rollers 220 is connected by a transmission gear 230. In order to address the problem of diverse specifications of scrap steel bars, the multi-wheel rotor 221 in the straightening rotor section 200 adopts a multi-diameter wheel design to adapt to different straightening requirements of scrap steel bars. The two sets of straightening rollers 220 work in sync with the transmission gear 230. The scrap steel bars are pulled and transported by the relative rotation of the two sets of straightening rollers 220.

The second pulley 513 is fixedly mounted on the shaft end extending from the shaft seat block 511; The transmission belt 514 is connected and installed on the first pulley 311 and the second pulley 513 to realize the transmission connection with the drive unit 300, so that the shaft 512 rotates synchronously with the straightening wheel 220 at the lower end.

[0032] The friction groove 515 is formed on the shaft column 512 to increase the friction between the scrap steel bars and ensure that the scrap steel bars are smoothly discharged.

The inner diameter of the multiple sets of inlet pipes 420 corresponds to the size of the working position for straightening the reinforcing bars formed between the multi-wheel rotors 221 of the upper and lower sets of straightening wheel components 220. For example... Figure 7 As shown, the inner diameter of the pipes decreases from left to right, with the pipe on the far left having the largest inner diameter and the pipe on the far right having the smallest inner diameter, to accommodate different specifications of scrap steel bars and improve the applicability of the lifting device.

[0036] Working principle: When the drive motor 330 is started, the power is reduced by the gearbox 310 and then transmitted to the mounting shaft 222 of the lower straightening wheel component 220, which drives the lower multi-wheel rotor 221 to rotate. The upper multi-wheel rotor 221 rotates synchronously through the transmission gear component 230. At the same time, the shaft column 512 of the guide shaft component 510 is driven to rotate via the belt drive.

[0037] The scrap steel bars are introduced from the inlet pipe 420 of the steel bar inlet 400 and enter the working position of the multi-wheel rotor 221 of the upper and lower straightening roller assembly 220. Under the rotation of the multi-wheel rotor 221, the steel bars are stretched and straightened. After straightening, the steel bars enter the outlet section and are stably exported under the cooperation of the friction groove surface 515 of the outlet shaft assembly 510 and the elastic pressure roller 522 of the lower pressure roller frame assembly 520.
