[0031] Specifically, the rotation of the output end of motor 41 is used to control the rotation of guide roller 45, so as to drive steel strip to transmit, and guide wheel 44 limits the upper side of steel strip and assists transmission.
[0032] Cold rolling mechanism 6 includes second L-shaped plate 64 and first L-shaped plate 63 fixedly connected to the upper side of workbench 1, the one side of first L-shaped plate 63 is bearing connected with second rotating shaft, and the outer side of second rotating shaft is sequentially fixedly connected with second roller, third roller and lower prefabricated roller 61, first roller is connected with second roller by belt, the upper side of second rotating shaft is equipped with third rotating shaft, the two ends of third rotating shaft are bearing connected with fixed frame 2 and the outer side is fixedly connected with upper prefabricated roller 67.
[0033] Specifically, the rotation of the output end of the motor 41 can also drive the second rotating shaft and the fourth rotating shaft to rotate, thereby driving the lower prefabricated roller 61 and the lower forming roller 66 to rotate. At the same time, the second rotating shaft and the fourth rotating shaft drive the first rotating shaft and the third rotating shaft to rotate, thereby driving the upper forming roller 62 and the upper prefabricated roller 67 to rotate.
[0034] The fourth rotating shaft is connected to one side bearing of the second L-shaped plate 64, and the outer side of the fourth rotating shaft is sequentially fixedly connected with the fourth roller and the lower forming roller 66.
