AI Technical Summary

Technical Problem

Traditional sheet-fed machines lack automatic adjustment capabilities in their take-up mechanism, causing the stacked materials to tilt or collapse as the height increases, affecting work efficiency and posing safety hazards.

Method used

The automatic lifting mechanism driven by a motor monitors the position of the receiving base plate through photoelectric sensors, and the PLC controller controls the motor to make the receiving base plate move smoothly on the frame. Combined with the gear and chain transmission system, it realizes the precise lifting and lowering of the receiving base plate, ensuring that the materials are stacked neatly and stably.

Benefits of technology

This allows for neater and higher material stacking, reduces the number of stacking and handling operations, improves production efficiency, avoids tilting or collapse, and ensures safety.

Abstract

This utility model relates to the field of printing equipment, specifically to an automatic lifting mechanism for sheet-fed printing presses. A motor drives a rotating shaft, which in turn drives a first gear, which in turn drives a first chain. The first chain drives a second chain and a third chain. Since one end of each of the second and third chains is connected to a receiving base plate, the receiving base plate slides on the frame. A first photoelectric sensor and a second photoelectric sensor monitor the highest and lowest positions of the receiving base plate on the frame, respectively. A PLC controller receives the position information from the first and second photoelectric sensors and controls the motor, enabling the receiving base plate to move smoothly. This results in neater and higher material stacking, reducing the number of stacking and handling operations and improving production efficiency. This invention solves the problem of existing sheet-fed printing press receiving mechanisms lacking automatic adjustment capabilities, which are prone to tilting or collapsing as the stacking height increases.
