Improvement of accelerated label conveying device in GDX1 soft packer

In order to prevent the thick labels from misalignment or out of position, via analyzing the working principle of label supplying system and the factors influencing the stability of label conveying and adopting toothed suction belt transmission technology, accelerated label conveying device in GDX1 soft packer was improved as following:1) A pair of gears were installed on the shafts of accelerating wheel and driven wheel separately to make them synchronously rotating in opposite directions, and the driven wheel was driven by gears instead of by friction. 2) Labels were conveyed via the engagement of driven wheel and accelerating wheel, for ensuring a steady conveying process, the clearance between the two wheels was set at 0.05 mm less than label's thickness. The results showed that after improvement, the running speed of GDX1 packer increased from 320 to 360 packets per minute, the machine efficiency raised by about 6.3 percentage points, and the labels were conveyed more steadily. The working surface of driven wheel was away from the bearing and sliding seat, cleaning and maintenance became more convenient. Meanwhile the maintenance period was prolonged from 2 to 4 hours above. The improved accelerated label conveying device was adaptive for labels of various thickness.
