Problems solved by technology

[0004] The disadvantages of this method are: 1. The position where the rewinding dust paper powder is generated is only at the cutter, and the paper powder generated at the cutter is not removed in time; 2. The suction pipe or the suction cover cannot touch the paper surface. There is some distance from the paper surface, and the paper powder on the paper surface cannot be completely removed

Abstract

The invention relates to a paper powder collecting device and a rewinding machine. The paper powder collecting device is used for sucking and removing paper powder generated when a cutter cuts paper.The paper powder collecting device comprises a cutter cover and a paper powder guide transferring pipe, wherein the cutter cover is used for containing the cutter, the paper powder is collected into the cutter cover, and the cotter cover is provided with a through hole; and the paper powder guide transferring pipe is used for transferring the paper powder in the cutter cover, and one end of the paper powder guide transferring pipe is connected with the through hole. According to the paper powder collecting device and the rewinding machine, the cutter cover is arranged to store the cutter, so that the paper powder generated when the cutter cuts the paper is located in the cutter cover, and the situation that the paper powder leaks or falls onto the surface of the paper is avoided; and the paper powder guide transferring pipe is connected with the cutter cover, accordingly, the generated paper powder can be sucked and removed in real time, and the removal effect of the whole paper powdercollecting device is improved.

Description

technical field [0001] The present application relates to the technical field of papermaking, in particular to a paper powder collecting device and a rewinding machine. Background technique [0002] In the paper industry, the rewinding machine cuts large paper rolls into small paper rolls according to the order specifications. During the rewinding and slitting process, a large amount of cutting paper powder is produced, which falls on the paper surface, enters the small paper roll, and attaches to the paper sheet. Adhesive paper dust on the paper will lead to printing white spots, increase the number of printing wipes, and seriously affect the quality and efficiency of printing. [0003] Most of the existing dust and powder removal devices for rewinders install suction pipes or suction hoods on the entire width of the paper or at a certain distance from the paper surface to suck away the dust and paper powder. [0004] The disadvantages of this method are: 1. The position ...
