The top of the guide roller 10 is slightly higher than the plane of the straightening table 1, so that the wire rod 8 is not worn by the front edge of the straightening table 1 during feeding, and baffle plates can be provided at both ends of the open groove 9 to prevent the wire rod 8 from deviating during feeding.

[0027] In addition, the feed straightening machine is also provided with an external industrial computer, which is electrically connected to the feed straightening machine as a whole, that is, the external industrial computer is electrically connected to the drive motor 14 to realize automatic start and stop of the drive motor 14; the external industrial computer is electrically connected to the electric slide rail 20, so as to control the fixed plate 31 to slide on the electric slide rail 20; the external industrial computer is electrically connected to the electric lifting rod 3, so as to control the height of the lifting base plate 4 to ensure that the feed height is flush with the straightening table 1; the external industrial computer is electrically connected to the electric slide rail 2 in the sliding groove 32, so as to realize the spacing adjustment between the pressing rollers 24; the external industrial computer is electrically connected to the electric slide rail 2 in the sliding groove 29, so as to control the movement of the limit rod 7 so as to adjust it according to the winding diameter of the wire rod bar 8, which is conducive to the placement of the wire rod bar 8; the feed straightening machine is automatically controlled by the external industrial computer to improve the feed straightening efficiency.

[0028] In addition, if the diameter of the wire rod 8 changes, the driving gear 16 and the driven gear 17 with a larger diameter can be replaced accordingly to ensure the stability of the meshing transmission and the straightening of the lower straightening wheel 19. The inner diameter of the straightening sleeve 30 is also changed with the diameter of the wire rod 8.

[0029] The specific working principle of the present invention is as follows: The drive motor 14 is started by the control of an external industrial computer, driving the rotation of the driving gear 16 and the driven gear 17 below, so that the pair of straightening wheels 19 below the driving gear 16 and the driven gear 17 can drive the wire rod 8 to feed. At the same time, by the control of an external industrial computer, the fixed plate 31 slides on the electric slide rail 20 in the long groove 18 to adjust the spacing between the straightening wheels 19, so that the straightening wheels 19 can straighten the wire rod 8. Then, the wire rod 8 enters the straightening seat 22 and is straightened again by the straightening sleeve 30. The wire rod 8 is further straightened by multiple pressing rollers 24 to enhance the straightening effect. Among them, the auxiliary straightening seat 21 shapes and supports the wire rod 8. In addition, as the wire rod 8 is fed, the height of the lifting base plate 4 is adjusted through the electric lifting rod 3, so that the wire rod 8 in the feeding trough 6 can be kept flush with the straightening table 1 during feeding, so as to better perform feeding and straightening.
