Description

Technical Field

[0001] The utility model belongs to the technical field of paper cutters, in particular to a paper cutter convenient for positioning. Background Technique

[0002] The paper cutter is a traditional product used to meet the paper cutting requirements in the later stage of printing. It has developed from a mechanical paper cutter to a tape-controlled paper cutter, and then to a microcomputer-programmed, color-display, fully-image-operated, visually-guided processing, and computer-aided cutting external programming and editing production data cutting system, which shortens the production preparation time. And when the product is processed, positioning is required. The existing paper cutter drives a positioning plate through an installed driving component to clamp the product, so as to achieve the effect of automatic positioning and ensure the processing accuracy. Although the processing accuracy of the device is ensured to a certain extent, installing multiple driving components to drive the positioning plate increases the manufacturing and use costs of the device.

[0003] After retrieval, a Chinese patent document (authorized announcement number CN213674365U), a paper cutter convenient for positioning, includes an operating table. The operating table is fixedly connected with a bracket, and a cutting component is connected to the bracket. The operating table is connected with a first positioning component and a second positioning component. The first positioning component includes a first cylinder and a first positioning plate. The first cylinder is horizontally fixedly connected to the operating table, and the first positioning plate is vertically arranged and fixedly connected to the piston rod of the first cylinder. The second positioning component includes two second cylinders and two second positioning plates. The second cylinders are horizontally fixedly connected to the operating table and perpendicular to the length direction of the first cylinder, and the second positioning plates are fixedly connected to the piston rods of the second cylinders. Although this patent ensures the processing accuracy of the device to a certain extent, installing multiple driving components to drive the positioning plate increases the manufacturing and use costs of the device.

Therefore, the control mode and circuit connection of the present utility model will not be explained in detail. And the drawing ratio is for reference only and can be adjusted to a certain extent according to the actual use situation.

[0029] Working principle

[0030] When in use, the paper cutting machine that is convenient for positioning places the product to be processed on the base 1, starts the driving motor 21 to drive the linkage block 24 on the side of the first lead screw 23 to adjust. The adjustment of the linkage block 24 drives the push plate 22 to move horizontally, so as to drive the product to move. Start two hydraulic rods 5 to drive the cutter 12 at the bottom of the linkage plate 6 to descend, so as to process the product. The adjustment of the linkage plate 6 drives the mounting box 7 at the top of the auxiliary plate 8 to move in linkage. The adjustment of the mounting box 7 drives the positioning plate 10 at the bottom of the auxiliary rod 9 to position and fix the product, ensuring the processing accuracy. After the processing is completed, start the hydraulic rod 5 to drive the cutter 12 and the positioning plate 10 to reset. Start the driving motor 21 to drive the push plate 22 to move in linkage, and blow the processed product to the blanking plate 34. Start the stepping motor 31 to drive the movable block 36 on the side of the second lead screw 37 to adjust, so as to drive the blanking plate 34 to perform the blanking operation on the processed product. During the blanking process, the connecting rod drives the cleaning brush 388 to move horizontally, so as to achieve the effect of automatically cleaning the shredded paper scraps.
