Embodiment Construction

[0017] Such as figure 1 , 2 Shown: the synchronous pulley 17 on the traction roller shaft 21 is connected with the synchronous pulley 3 of the servo motor 1 by the synchronous belt 8, and only utilizes the power of the servo motor 1 to drive the traction drum installed on the traction roller shaft 21 to rotate, the servo The motor 1 is connected to the encoder by wires, and the action of the servo motor 1 is controlled by the encoder. The rotation speed of the traction roller is controlled by changing the rotation speed of the servo motor 1. Compared with the original method of controlling the rotation speed of the traction roller through a whole set of speed change mechanism, the present invention has the characteristics of simple structure, high control precision, convenient operation and fast response speed. . When working, the encoder sends instructions according to the obtained data, so that the servo motor can change its speed in time according to the actual situation ...

Abstract

A servo drive method and mechanism for the folding drive roller is disclosed. The belt wheel of drive roller is coupled with the belt wheel of servo motor via a synchronous belt, so the drive drum installed onto drive roller is driven by the servo motor connected electrically with a cooler for controlling it by the coder.

Description

technical field [0001] The invention relates to a printing machine, in particular to a servo driving method and a driving mechanism on a folding traction roller. Background technique [0002] The traction roller is a main component in the folding unit of the shaftless transmission tower newspaper machine. The traditional traction roller is shown in Figure 4 and 5: the power is transmitted to When the traction roller 21 needs to change the size of the traction force, that is, to adjust the differential speed with the printing unit, it is necessary to replace the two exchange gears 45, 46 of the differential gearbox 43 to ensure that the output shaft installed on the differential gearbox The rotating speed of bevel gear 47. The disadvantage of this structure is: the structure is relatively complicated, and a set of gears needs to be replaced every time the differential speed is adjusted, and the operation is cumbersome. Contents of the invention [0003] The purpose of the...
