technical field

The invention relates to the field of printing transmission devices, in particular to a forward and reverse conversion transmission device of a unit gravure printing machine.

Background technique

Gravure printing, referred to as gravure printing, is one of the four printing methods. Gravure printing is a direct printing method. It directly impresses the ink contained in the gravure pits onto the substrate. The shades of the printed picture are determined by the size and depth of the pits. Unit type gravure printing machine During the working process, it is necessary to adjust the positive and negative rotation of the printing roller. The existing transmission device for the positive and negative conversion of the unit gravure printing machine mainly makes the input of the transmission device through the cooperation of multiple sets of clutches, couplings and gears. Shaft and output shaft rotate in the same direction, or rotate in opposite directions.

The existing forward and reverse conversion transmission device can only switch the steering in the stop state, and the separation and cooperation of the two sets of binding elements will not cause collision damage to the binding elements. Switching is performed, in which one group of binding elements that fit together is forcibly separated, while one of the other group of binding elements is rotating at a high speed, and the other binding element is in a stalled state, and the stationary binding elements cooperate with the high-speed rotating binding elements During the process, the high-speed rotating conjugate will have a strong collision with the stalled conjugate at the moment of contact, and then drive the stalled conjugate to rotate, and under the continuous push of the stalled conjugate, make the conjugate It can stably follow the high-speed rotation of the coupling drive, but in the non-stop state, each time the coupling will collide during the mating process, and the coupling will be easily damaged. For this reason, we propose a unit-type gravure printing machine. Forward and reverse conversion transmission.
