[0035] The straightened copper strip first passes through the gaps between the two first conveying rollers 62 and the gaps between the two second conveying rollers 63, at this time, the first conveying rollers 62 and the second conveying rollers 63 rotate relative to the top of the first conveying support plate 61, and play a role in supporting and guiding the copper strip. Moreover, the gaps between the two first conveying rollers 62 support the upper and lower end faces of the copper strip, and the gaps between the two first conveying rollers 62 support the left and right end faces of the copper strip, so that the copper strip has better support during conveying.

[0036] Similarly, the straightened copper strip will then pass through the gaps between the plurality of third conveying rollers 72, at this time, the third conveying rollers 72 rotate relative to the top of the second conveying support frame 71, and play a role in supporting and guiding the copper strip.

[0037] Principle and method of use of the utility model:

[0038] First, the copper strip to be straightened is transmitted to the inside of the copper strip heating groove 54, and then the heat generated by the first heating plate 52 and the second heating plate 53 can be transmitted to the surface of the copper strip. The plasticity of the copper strip is significantly enhanced at high temperature, the internal stress is reduced after heating, and the external force required for straightening is reduced.

Each second supporting roller shaft 32 is also driven by the second bevel gear 34 to rotate, and at the same time, each second straightening wheel 33 starts to rotate. At this time, when the copper strip is located between the two first straightening wheels 24 and the two second straightening wheels 33, each first straightening wheel 24 and second straightening wheel 33 can straighten the horizontal or vertical end face of the copper strip.

[0040] Finally, the straightened copper strip will first pass through the gap between the two first conveying rollers 62 and the gap between the two second conveying rollers 63. At this time, the first conveying roller 62 and the second conveying roller 63 rotate relative to the top of the first conveying support plate 61, which supports and guides the copper strip. Moreover, the gap between the two first conveying rollers 62 supports the upper and lower end faces of the copper strip, and the gap between the two first conveying rollers 62 supports the left and right end faces of the copper strip, so that the copper strip has better support during conveying.
