Thin paper winding apparatus having reverse poking mechanism

Abstract

The invention relates to a flimsy winding device provided with a reverse pulling-apart mechanism, which comprises an upper roller and the reverse pulling-apart mechanism. Flimsy is close attached to the roller surface of the lower half of the upper roller and winds a paper tube along a preset transfer direction; the reverse pulling-apart mechanism is arranged below the upper roller and comprises a rotating shaft, at least a shifter lever and a drive mechanism; the shifter lever is arranged on the outer torus of the rotating shaft and comprises a rotating shaft connection end and a press touching end which extends from the outer torus of the rotating shaft in a protruding manner; the drive mechanism is used for driving the shifter lever to rotate around the rotating shaft; the rotation direction of the shifter lever is opposite to the transfer direction of the flimsy. When being driven to rotate to the truncation position by the drive mechanism, the press touching end of the shifter lever just leads the flimsy which passes through the space between the upper roller and the press touching end to be clamped and provides a pulling-apart force along the opposite direction to enable the flimsy to be pulled apart.

Description

technical field [0001] The invention relates to the design of a thin paper winding device, in particular to a thin paper winding device with a reverse pull-off mechanism. Background technique [0002] The paper tube of a general thin paper winding device is delivered to an upper roll by a conveyor, then pushed into a guide plate channel by a push rod, and then reaches a winding area, where the thin paper is wound on the paper tube. Paper becomes a roll of paper, such as a roll of toilet paper, etc., as disclosed in U.S. Patent No. 5,769,352. The rotating rod, that is, use a rotating rod whose rotating speed is slightly slower than the rotating speed of the winding wheel to break off the thin paper, and the rotating direction of this rotating rod is the same as the transmission direction of the thin paper. Or, some manufacturers also control the rotation speed of a rotating rod so that the relative speed is faster than the speed difference of the winding wheel to cause the t...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned existing tissue paper winding device, it must be noted that the rotation speed of the rotating rod cannot be the same as the rotation speed of the winding wheel, so as to cause a speed difference and cause the tissue paper to break, and if the tissue paper is made of high toughness material When it is made, if the speed difference between the rotating rod and the winding wheel is not large enough, it will not cause the thin paper to break

[0005] Furthermore, the rotation direction of the rotating rod in the existing tissue paper winding device is the same as the transmission direction of the tissue paper, and it cannot absorb the tissue paper, which does not help the tissue paper to be wound on the paper tube
