Description

Technical Field

[0002] In the papermaking industry, the paper aligner is one of the key equipment, which is used to sort and position the paper to ensure that the quality and specifications of the paper meet the production requirements. Through the synergy of precise mechanical movement and electronic control system, the paper aligner can achieve efficient and accurate paper sorting and output;

[0003] It has been found in actual use that the existing paper finishing machine rotating structure has the following shortcomings:

[0004] When the rotating structure of the existing paper finishing machine drives the paper pile to rotate, due to the weight of the paper pile, the paper pile is prone to inertia during rotation, and the rotating table is prone to end jump and eccentricity, which affects the stability of the rotating motion. When used for a long time, it will cause backlash and shorten the life of the rotating structure of the whole machine.

[0005] In addition, after the rotation, when the paper pile is blown, the gap between the paper pile and the rotating support mechanism is small, and the air volume cannot blow through a large area to contact the bottom of the paper pile, making the blowing effect unsatisfactory and resulting in poor paper arrangement;

[0006] Therefore, the present application provides a paper finishing machine rotation drive mechanism to drive the hydraulic rotary support table rotation structure to meet the needs. Utility Model Content
