[0002] In the existing production and molding process of PVC plastic door curtain, the pressing of the plastic door curtain of PVC sheet is generally completed through the calendering part in the sheet material production line. During calendering, the sheet is rolled by three calender rollers. In production, due to Different product needs have different requirements for the forming thickness of PVC sheets, so it is often necessary to adjust the gap between the three calender rollers. In the existing adjustment device, each smooth roller is controlled by three screw screws at both ends of the smooth roller. Position adjustment, which is easy to cause product thickness error, and the adjustment process is not easy to operate, which affects product quality and production efficiency

Embodiment Construction
[0007] Describe the embodiment in detail in conjunction with the accompanying drawings, loosen the locking block 4, turn the handle 5, and the lead screw rotates 6 to drive the lever 7, the lever lifts the calender roller 2 to adjust the gap with the calender roller 1, and then tightens the lock block, that is, to fix the position of the calender roller 2, then loosen the locking block, turn the handle 5, and the lead screw 6 rotates, a shaft sleeve is installed on the lead screw, a bracket 8 is arranged on the shaft sleeve, and a calender roll 3 is installed on the bracket. The support moves horizontally, adjusts the gap with the calender roll 2, and then tightens the locking block, that is, fixes the position of the calender roll 3. During production, the PVC sheet is first calendered by calender roll 1 and calender roll 2, and then calendered by calender roll 2 and calender roll 3. The calendering effect of the product is good, the product error is small, and the product is ...
