An automatic stop bidirectional paper cutter

Abstract

The invention discloses an automatic intermittent two-way paper cutting machine. The automatic intermittent two-way paper cutting machine comprises an unwinding roll, a longitudinal cutting mechanism,a pull roll, a transverse cutting mechanism and a paper conveying mechanism. The pull roll is connected with an intermittent mechanism. The intermittent mechanism comprises a driving gear, a shiftingshaft, a driven gear and a shifting rod. The intermittent mechanism and the transverse mechanism are connected with a transmission mechanism. A paper storage tank is arranged below the paper conveying mechanism. According to the automatic intermittent two-way paper cutting machine, automatic intermittency of the pull roll can be achieved through the pull ross. In the intermittent process, the transverse cutting mechanism conducts transverse cutting on paper sheets to prevent the paper sheets from being conveyed continuously, colliding with a transverse cutter and damaged by the transverse cutter in the transverse cutting process. Synchronous operation of the pull roll and the transverse cutting mechanism is achieved. The longitudinal cutting mechanism is provided with an automatic supporting device, and supporting shafts automatically support the paper sheets. Meanwhile, tensioning guide rolls are mounted on the automatic supporting device and can automatically tension the paper sheets in the automatic supporting process and facilitate better cutting by a longitudinal cutter.

Description

technical field [0001] The invention relates to the technical field of paper processing, in particular to an automatic stop bidirectional paper cutter. Background technique [0002] The paper slitter is a device that cuts the whole roll of paper according to the needs. For example, A4 paper and A3 paper are first cut by setting the paper slitter and then cut crosswise. In the prior art, the slitting components of the slitting machine are all fixed on the supporting rollers. When the paper is transported, the knife edge automatically cuts the paper along the longitudinal direction, and when it needs to be cut horizontally, the paper needs to be transferred to the horizontal slitter. On the cutting machine, this not only delays the working time, but also makes the operation inconvenient. [0003] In the prior art, for example, the Chinese patent publication number CN206416207U provides a single-watt vertical and horizontal paper cutter, which includes a support seat, and fixe...

Problems solved by technology

This application has a simple structure and has both horizontal and vertical cutting functions. However, if the paper feeding unit does not stop when the paper is sent to the cross-cutting mechanism after being slit by the slitting mechanism, the paper will be cut after the cross-cutting knife is cut. Continuing to feed, causing paper to wrinkle or subsequent cross-cutting to damage the paper
