Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to an automatic paper cutter. Background Art

[0002] Paper cutter is a traditional product used to handle the paper cutting needs in the later stage of printing. It has developed from mechanical paper cutter to tape-controlled paper cutter, and then to microcomputer-controlled, color-displayed hydraulic double-digital paper cutter. Paper cutter is a kind of cutting machine with a wide range of uses, and can be used to cut paper, leather, plastic, cardboard and other materials. Paper cutter is mainly composed of control console, host, workbench, paper pusher, cutting device, etc.

[0003] When a traditional paper cutter cuts paper, if it needs to cut two, three or four sides of the paper, it is usually necessary to manually rotate the paper after cutting one side and then position it. The entire cutting process is cumbersome and inefficient. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic paper cutter to solve the problems raised in the above background technology.

The workbench is provided with a circular hole, in which a disc is installed for rotation by a stepping motor. Three pushers are also arranged on the workbench around the circular hole. The pushers are in a U-shaped structure, driven by a driving assembly arranged on the workbench, and adjacent pushers are arranged at right angles to each other.

[0007] As a further solution of the utility model: the driving assembly includes a pushing unit with the same number as the pushing member, the pushing unit includes a screw rod and a nut, a strip groove is opened on the workbench, the screw rod is rotatably set in the strip groove and is driven by a servo motor set in the strip groove, the nut is installed on the screw rod and slidably set in the strip groove, and the pushing member is fixedly installed on the nut.

[0008] As a further solution of the utility model: a movable disk is also installed on the disc through a telescopic unit, the height of the movable disk is higher than the height of the workbench, and the movable disk is symmetrically provided with rotating grooves, and a plurality of conveying rollers are arranged in parallel to rotate in the rotating grooves, and conveying belts are installed on the plurality of conveying rollers, and one of the conveying rollers is driven by a micro motor arranged in the movable disk.

[0009] As a further solution of the utility model: the telescopic unit includes a sleeve fixedly mounted on the disc, a boss movably inserted in the sleeve, and an elastic member installed between the boss and the sleeve, and the boss is fixedly mounted on the bottom surface of the movable disc.

[0010] As a further solution of the utility model: a support seat is fixedly arranged on the side of the cutting mechanism above the movable disk, a cylinder is installed on the support seat, and a pressure plate is fixedly installed on the telescopic end of the cylinder.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a disc, a stepping motor and three pushing members. When cutting the paper on multiple sides, the stepping motor drives the disc to rotate, and the paper cutting side can be automatically switched. When the three pushing members are driven to push in the direction of the paper, the pushing members on both sides of the paper can ensure that the paper is stacked neatly, and the pushing member on the side away from the cutting mechanism can push the paper toward the cutting mechanism and realize the paper cutting. The whole cutting process does not need manual assistance, which reduces the labor intensity of workers and improves the paper cutting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] Example 1

[0021] See also Figure 1-5 , an automatic paper cutting machine, comprising a workbench 1, a cutting mechanism 2 installed on the workbench 1 and a control console 3 installed on the cutting mechanism 2, the workbench 1 is provided with a circular hole, a circular disc 4 is installed in the circular hole by a stepper motor 17, three pushers 5 are arranged on the workbench 1 around the circular hole, the pushers 5 are in a "U"-shaped structure, the pushers 5 are driven by a driving assembly arranged on the workbench 1, and adjacent pushers 5 are arranged at right angles, by arranging the circular disc 4, the stepper motor 17 and the three pushers 5, when the paper is cut on multiple sides, the stepper motor 17 drives the circular disc 4 to rotate, and the paper cutting surface can be automatically converted, and when the three pushers 5 are driven to push in the direction of the paper, the pushers 5 on both sides of the paper can ensure that the paper is stacked neatly, and the pusher 5 on the side away from the cutting mechanism 2 can push the paper to the cutting mechanism 2 and realize the paper cutting, and the whole cutting process does not need manual assistance, which reduces the labor intensity of workers and improves the paper cutting efficiency.

[0022] Among them, the driving assembly includes the same number of pushing units as the pushing member 5, and the pushing unit includes a screw rod 7 and a nut. A strip groove 6 is opened on the workbench 1. The screw rod 7 is rotatably set in the strip groove 6 and is driven by a servo motor 8 set in the strip groove 6. The nut is installed on the screw rod 7 and slidably set in the strip groove 6. The pushing member 5 is fixedly installed on the nut.

[0023] In addition, a movable disk 9 is also installed on the disc 4 through a telescopic unit. The height of the movable disk 9 is higher than the height of the workbench 1, and a rotating groove is symmetrically opened on the movable disk 9. A plurality of conveying rollers 10 are arranged in parallel and rotate in the rotating groove. A conveying belt 11 is installed on the plurality of conveying rollers 10, and one of the conveying rollers 10 is driven by a micro motor arranged in the movable disk 9. Specifically, the telescopic unit includes a sleeve 12 fixedly mounted on the disc 4, a boss 13 movably inserted in the sleeve 12, and an elastic member installed between the boss 13 and the sleeve 12. The boss 13 is fixedly mounted on the bottom surface of the movable disk 9. The movable disk 9, the conveying roller 10 and the conveying belt 11 are arranged. After the paper is cut, the conveying belt 11 can drive the paper to move on the movable disk 9, so as to adjust the position of the paper again. The arrangement of the telescopic unit can reduce the friction resistance between the paper and the surface of the workbench 1 before the paper is cut, and further facilitate the adjustment of the position of the paper by the conveying belt 11.

[0024] Example 2

[0025] This embodiment is improved on the basis of embodiment 1, specifically:

[0026] See also Figure 2A support seat 14 is fixedly arranged on the side of the cutting mechanism 2 above the movable disk 9, and a cylinder 15 is installed on the support seat 14. A pressing plate 16 is fixedly installed at the telescopic end of the cylinder 15. The telescopic cylinder and the pressing plate 16 are arranged so that when the cutting mechanism 2 cuts the paper, the cylinder 15 can drive the pressing plate 16 to press the paper downward in the vertical direction. After being pressed down, the paper is laid flat on the workbench 1, which effectively avoids the phenomenon of uneven cutting surface caused by the arching of the paper.
