Reel unwinding and printing printing without serial axis fixed unit

Abstract

The invention relates to the field of web printing and coating production. The technical solution is: roll material unwinding and printing without string axis fixed unit, characterized in that the unit includes a base, left and right wall panels vertically fixed on the left and right sides of the base, and the two ends are respectively rotatably positioned on The transfer tray on the left and right wall panels, the transposition power motor that drives the transfer tray to rotate, the first left clamping head that is coaxially installed on the transfer tray and spaced apart to clamp the A-axis roll material and the first right clamping machine head, the second left clamping machine head and the second right clamping machine head, which are coaxially installed on the transfer plate and spaced apart to clamp the B-axis roll material, the first bridge transmission mechanism and the second Two bridge transmission mechanism. The unit can adapt to rolls of different widths without manual shafting, which greatly reduces the labor intensity of the staff, and drives the rolls to rotate through bilateral transmission. It has reasonable structure, reliable operation, convenient operation, and is suitable for automation applications and production. Features of high efficiency.

Description

technical field [0001] The invention relates to the field of roll material printing and coating production, in particular to a roll material unwinding and printing non-series axis fixing unit. Background technique [0002] In the current roll material printing machine, the unwinding and rewinding of the material is done manually by first passing the air expansion shaft through the shaft hole of the entire roll material, and then using a rickshaw to lift and lower the two ends of the air expansion shaft on the discharge frame. Then blow air to the air shaft to fix the air shaft and the roll material, so as to realize discharging and receiving. In addition, in order to ensure continuous printing in the production process, it is necessary to replace the old roll material that is about to run out with new roll material; therefore, two unwinding shafts for alternate unwinding are generally installed on the unwinding frame of the printing machine, referred to as A axis and B axis...

AI Technical Summary

Problems solved by technology

[0003] Due to the large size and wide format of coiled materials in industries such as wood-based panels, home furnishing, flooring, packaging, and decoration, the corresponding roll material positioning air shaft has a large width and heavy weight, and the AB shaft does not stop for refueling during the production process. Large, manual shaft loading and unloading is very labor-intensive, and it is easy to damage the parts; in addition, the existing roll material drive is unilateral drive, that is, the drive motor drives one end of the air shaft to rotate; the string shaft type The overall setting of the air expansion key on the air shaft has a better fixing effect during the rotation process with a large torque. The disadvantage is that it needs to be assembled manually, and the labor intensity caused by frequent disassembly of the air shaft is very high.
