Description

Wave type paper feeder

Technical Field

The utility model relates to corrugated board processing equipment, in particular to a wave type paper feeder.

Background

In corrugated board processing production, it is necessary to feed corrugated boards stacked together one by one to the subsequent process using a paper feeder. In the paper feeding process, the paper feeding part of the paper feeder rubs the corrugated boards stacked on the lowest layer and the upper layer through the intermittent rotating paper feeding wheels, when the tail part of the lowest layer of corrugated boards is close to the paper feeding part, the paper feeding part of the paper feeder lifts the corrugated boards through the small liftable glue wheels, so that the corrugated boards are separated from the paper feeding wheels, and then the corrugated boards are clamped by the rollers on the later procedure to be extracted from the upper part of the paper feeding part. When the existing paper feeder is used for supporting the corrugated paper board, all the small rubber wheels are lifted at the same time so as to separate the corrugated paper board from the paper feeding wheels. However, when the size of the corrugated board is smaller, two problems can occur when the small rubber wheel is lifted at the same time, one is that the roller in the later procedure lifts up the small rubber wheel under the condition that the corrugated board is not clamped yet, so that the corrugated board and the paper feeding wheel are separated from contact, and paper feeding cannot be completed; a further problem is that the latter rollers, while gripping the board, have fallen without completely removing the corrugated board from the machine with the small glue wheel, resulting in repeated feeding of the paper by simultaneous contact of the wheel with the multi-layered board.
