Fully automatic CZ combination Purlin Machine (Model CZ):

A high-tech, programmable machine that produces both C and Z purlins with quick, automatic adjustments—ideal for flexible, precise output.

Leveling feed

The leveling mechanism in the machine is mainly composed of a feeding roller (guiding and feeding roll), a guiding roller (tracting and driving the material roll to feed at a certain speed), and leveling roller. Among them, the function of leveling the coil material is the leveling roller in the right picture. In this example, it is an upper ,3 lower 4 structure. For rolls of different materials, different thicknesses, and different hardness, other equipment is also equipped with an upper 2 lower 3 structure or no leveling structure (for example, the G550 material used by LG has a relatively hard hardness, and the roll can still maintain a good flatness, so no leveling mechanism was added to the design).

Pre-punching and pre-shearing

The function of the pre-shearing is to trim the end of the material roll to ensure that the end of the material roll is even, and the pre-shearing can also be cut to length according to production requirements. The advantage of pre-shearing is that there is no waste materi,al and the shearing speed is fast. The disadvantage is that it cannot produce short materials, and the shape of the plate is easy to open. (Slab shape opening: the opening means that the verticality of the profile section is greater than 90°, which is beyond the required range of the plate shape.)
