In addition, straight edges are likely to appear on both ends of the material after rolling, resulting in low yield and low processing efficiency, which is not conducive to improving the competitiveness of the enterprise.

[0026] The first bending roller 2 is sleeved with a soft rubber layer, and the second bending roller 3 is made of a hard material. The second bending roller 3 and the first bending roller 2 are arranged in close contact.

[0027] Through the soft-hard matching structure setting, the second bending roller 3 can bend the material on the soft rubber layer through the matching of the soft rubber layer.

[0028] The curling mechanism with a pre-pressing structure further comprises two sets of bending adjustment components, which are respectively arranged at two ends of the second bending roller 3 .

[0029] By setting the bending adjustment component, the second bending roller 3 can change the relative distance with the first bending roller 2 through the bending adjustment component, thereby changing the arc size of the pre-bending of the material.

[0030] The bending adjustment assembly includes a bending locking piece 4, a bending push block 5 and a bending swing adjustment piece 6.

[0032] The roller driving mechanism comprises a first active roller 7 , a second active roller 8 and a third driven roller 9 , and the first active roller 7 , the second active roller 8 and the third driven roller 9 are parallel to each other.

[0033] The first active roller 7, the second active roller 8 and the third driven roller 9 are arranged in a triangle when viewed from the end direction.

[0034] The roller driving mechanism includes a driving motor 10 and a linkage gear set 11. The moving end of the driving motor 10 is connected to the linkage gear set 11. The linkage gear set 11 is respectively connected to the first active roller 7, the second active roller 8 and the first bending roller 2. The driving motor 10 can simultaneously drive the first active roller 7, the second active roller 8 and the first bending roller 2 to rotate through the linkage gear set 11.

[0035] The first active roller 7, the second active roller 8 and the third driven roller 9 are all made of hard materials. Through the setting of the hard materials, the material can be effectively rolled into a circle according to the set shape, which solves the problem of error in the pressing curvature caused by the traditional use of soft rubber materials.

[0036] The rolling mechanism with a pre-pressing structure further comprises two sets of rolling adjustment components, which are respectively arranged at two ends of the third driven roller 9 .

[0037] By setting the curling adjustment component, the third driven roller 9 can change the relative distance between the first active roller 7 and the second active roller 8 through the curling adjustment component, so as to adjust the curvature of the material curling.

[0038] The curling adjustment component includes a curling locking piece 12, a curling push block 13 and a curling swing adjustment piece 14. The curling mechanism bracket 1 is provided with a curling groove 102 that cooperates with the curling push block 13. The curling locking piece 12 can lock the curling push block 13 in the curling groove 102. The curling swing adjustment piece 14 is connected to the third driven roller 9.

[0039] By setting the curling swing adjusting member 14, the relative angles between the third driven roller 9 and the first active roller 7 and the second active roller 8 can be adjusted, thereby further improving the flexibility of adjusting the third driven roller 9 and flexibly changing the curling curvature.

[0045] A guiding slope 17 is arranged on the rolling mechanism bracket 1, and the guiding slope 17 is arranged below the rolling roller mechanism. The guiding slope 17 can cooperate with the rolling roller mechanism to discharge the material.

[0046] The working process of the rolling mechanism with a pre-pressing structure provided in this embodiment is as follows: Compared with the existing rolling mechanism, the embodiment of the utility model provides the advantage of convenient feeding.

[0047] The operator places the steel bar into the pre-bending mechanism for pre-bending.

[0048] After the pre-bending is completed, the pre-bending mechanism sends the pre-bent material between the first active roller 7 , the second active roller 8 and the third driven roller 9 .

[0049] After the bending is completed, the material is separated from the rolling roller mechanism, falls onto the guide slope 17, and then enters the material receiving box.

[0050] The adoption of this mechanism can effectively solve the problems of low processing efficiency and poor user experience of the rolling mechanism in the prior art. By using this product structure, the pre-bending mechanism pre-bends the material so that the material has a certain curvature and can be smoothly fed into the rolling roller mechanism, which improves the processing experience of the processing personnel while improving the processing efficiency, which is beneficial to improving the competitiveness of the enterprise.
