Description

Paper feed positioning mechanism of paper cutter

Technical Field

The utility model relates to a paper cutter technical field specifically is a paper feed positioning mechanism of paper cutter.

Background

In the production process of paper and packaging paper boards, facial tissue needs to be cut according to a certain specification. A paper cutter is a device that cuts tissue. The paper cutter includes frame and cutter, and the frame is provided with the horizontally workstation, and the cutter rear is provided with the baffle that the opposite paper goes on fixing a position. The face paper to be cut is placed on the workbench in order, then the face paper is pushed forwards, and the face paper is positioned forwards and backwards through the baffle plate, so that the cutting size of the face paper is determined; the cutter falls down and the complete facial tissue is cut. When the cutter conveys the paper, the paper needs to be manually put on the workbench and manually aligned, and then the paper is pushed to the cutter to complete the cutting of the paper. Hidden safety hazards are hidden in manual paper pushing, after workers push paper for a long time, attention is not focused, accidents occur easily, manual paper pushing needs to be carried out manually to align, the regularity of manual alignment cannot be guaranteed, and the cutting of corners of finally produced paper is not in place, so that the product quality is affected.

The existing Chinese patent with the publication number of CN210456732U discloses a paper feeding positioning device of a paper cutting machine, which comprises a bottom plate, wherein a paper cutting mechanism is arranged on the bottom plate, the paper cutting mechanism comprises a door frame and a paper cutter which is arranged on the door frame and can move vertically, a first positioning plate and a first hydraulic pushing mechanism are arranged on the input side of the paper cutting mechanism, a first push plate is arranged at the end part of a push rod of the first hydraulic pushing mechanism, and the first push plate and the first positioning plate are perpendicular to each other; the output side of the paper cutting mechanism is provided with a second positioning plate which is parallel to the paper cutting mechanism, and the two sides of the output side of the paper cutting mechanism are provided with a lifting plate and a second push plate. Adopt above-mentioned structure, through a plurality of locating plates, realize the accurate location of input paper, avoid artifical manual propelling movement paper to take place the incident, reduced the safety risk, can all reach the purpose of accurate cutting to different papers according to the size of input paper and the size that needs cut out, corresponding regulation locating plate position simultaneously.

However, in practical application, the above scheme has the following problems: in order to ensure that the size of each stack of paper is consistent, four edges of the paper need to be cut in the cutting process, the paper feeding positioning device in the scheme can only cut and position one edge of the paper, the edge of the paper still needs to be manually changed to cut after the single edge of the paper is cut, time and labor are wasted, and the requirement for cutting the paper cannot be met.
