Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a paper feeding and air blowing regulating structure of a paper cutter. Background Art

[0002] A paper cutter is a machine used to handle paper cutting needs in the later stage of printing. The main principle is to use the movement of the tool to cut paper. Compared with traditional manual cutting, the paper cutter can shorten the production preparation time, increase the cutting accuracy, reduce the labor intensity, and make the operation safer.

[0003] The utility model patent application document with publication number "CN218748169U" discloses a precise measurement and positioning mechanism for a paper cutter, which is mainly composed of an operating table, a paper cutting mechanism, a paper cutter, an electric telescopic rod, a paper pusher, a mounting block and a laser ranging transmitter. The technical solution is provided with a mobile measurement and feeding assembly composed of an electric telescopic rod, a paper pusher, a laser ranging transmitter and a ranging receiver. While the electric telescopic rod drives the paper pusher to move, the laser ranging transmitter and the ranging receiver are used to measure the moving distance of the paper pusher. After reaching the set paper cutting length, the electric telescopic rod automatically stops moving, and then the paper cutting mechanism is controlled through the control panel, thereby achieving the effect of precise measurement of paper cutting.

[0004] The precise measurement and positioning mechanism of the paper cutter disclosed in the above document has the following defects: during the use of the push board of the precise measurement and positioning mechanism of the paper cutter, if there is static electricity on the push board or the paper, it is very likely that the paper debris after cutting will be adsorbed on the push board, affecting the subsequent use of the push board.

[0005] It can be seen from this that the existing paper cutting machine's push paper board cannot remove paper scraps, and it is necessary to improve the existing shortcomings and provide a paper feeding and blowing adjustment structure for the paper cutting machine. Utility Model Content
