Description

Ultra-wide conveying line and cleaning machine

Technical Field

Background

Before leaving the factory, the surfaces of the sheets and the films need to be cleaned by using a cleaning machine, and the cleaning machine adheres to impurities such as dust on the sheets by using a rubber roller. Besides the main body for realizing the cleaning function, the cleaning machine is also provided with conveying lines on two sides for conveying sheets and films. The width of the disposable cleaning sheet of the existing cleaning machine is limited, so that the width of the cleaning machine is required to be increased for cleaning large-size sheets and films, and the width of a conveying line is also required to be increased.

Most of the existing conveyor lines are belt conveyor lines or roller conveyor lines, and the limiting factor of the width of the conveyor lines is that the length of the transmission shafts is limited. When the driving shaft is too long, bending is easily generated in the middle part of the driving shaft, and if the driving shaft is simply thickened, excessive assembly space is occupied, and a narrow sheet is not adapted. If the driving shaft is simply lengthened, the assembly difficulty is high, the conventional fixing hole is not matched, and if the conventional fixing hole is matched with the diameter of the driving shaft, the conventional fixing hole is difficult to pass through and is easy to wear, and dust is generated; if the fixing hole is too large, a gap is easily generated, so that the driving shaft is easy to shake.
