Technical Field

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

[0002] Paper cutters are traditional products used to handle paper cutting needs in the post-printing phase. They have evolved from mechanical paper cutters to tape-controlled paper cutters, and further to cutting systems with microcomputer control, color display, full-image operation guidance, visual processing, and computer-assisted cutting, with external programming and editing of production data. These systems have shortened production preparation time, achieved higher cutting accuracy, reduced labor intensity, and made operations safer.

[0003] During the production process, in order to cut paper of corresponding thickness and achieve the best paper cutting effect, it takes a lot of time to manually replace the blade of the paper cutter, which has high labor costs. Therefore, we propose a CNC paper cutter. Utility Model Content

Therefore, the above terms should not be understood as limitations on the present invention.

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0032] Example:

[0033] See also Figures 1-6 The cam 7 is a kind of cam 7 that is fixed on the platform 1 of paper cutting machine, and the cam 7 of paper cutting machine is provided with the support 2 of the cam 7.

[0034] In an embodiment of the present application, a fixing groove 16 is provided on the paper cutter platform 1, and the fixing groove 16 is provided directly below the cutting frame 2. A cutting pad 17 is embedded in the fixing groove 16. The cutting pad 17 of different hardness is replaced according to the characteristics of the cut paper, which can not only protect the blade 5, but also achieve the best cutting effect.

[0035] In the embodiment of the present application, an elastic telescopic frame 19 is symmetrically fixed to the outer side of the bottom of the mounting frame 4, and a pressure rod 20 is fixed to the movable end of the bottom of the elastic telescopic frame 19, which can not only position the cutting point, but also prevent the blade 5 from accidentally cutting fingers, etc.

[0036] During the implementation process, the cutting blade 5 is fixedly installed in the mounting frame 4 through the cylinder bolt 9, and the spare blade 5 is placed in the blade holder 8 through the cylinder bolt 9. When the cutting blade 5 needs to be replaced, the control box 6 is controlled by the CNC track to move toward the cutting frame 2 until the mounting column 7 with the spare blade 5 is placed directly below the mounting frame 4, the idle blade holder 8 on the mounting column 7 is rotated to the top, and then the blade 5 on the mounting frame 4 moves down together with the mounting frame 4 until the blade 5 is inserted into the slot 12 of the blade holder 8. During the process of 12, the symmetrically distributed sponge pads 13 fixed at the bottom inner side of the slot 12 can protect the blade of the blade 5 until the output end of the cylinder bolt 9 is inserted into the limiting hole 11 of the blade 5, and the replaced blade 5 is stored on the blade holder 8. Then, the required blade 5 is rotated to the top by rotating the mounting column 7, and the tail end of the blade 5 is inserted into the mounting frame 4. The movable end of the cylinder bolt 9 on the mounting frame 4 is inserted into the mounting hole 10 of the blade 5, and the required blade 5 is installed and fixed in the mounting frame 4. The entire process is controlled by an external computer, without manual labor, saving time and effort.

[0037] It should be noted that, in the process of inserting the blade 5 into the slot 12 of the blade holder 8, in order to prevent the air squeezed by the blade 5 in the slot 12 from being unable to be released, thereby preventing the blade 5 from being smoothly stored and inserted, a first ventilation groove 14 is provided on both sides of the slot 12, and a second ventilation groove 15 is symmetrically provided on both sides of the blade 5. Therefore, when the blade 5 is inserted into the slot 12, the first ventilation groove 14 is connected to the second ventilation groove 15, and the compressed air in the slot 12 can be discharged through the first ventilation groove 14 and the second ventilation groove 15, thereby ensuring that the blade 5 is smoothly stored in the blade holder 8.

[0038] At the same time, the top of the second ventilation groove 15 passes through the top of the blade 5, but the bottom is located above the cutting edge of the blade 5, which ensures the cutting strength of the cutting edge of the blade 5.

[0039] In the embodiment of the present application, a fixed groove 16 is provided on the paper cutter platform 1, and the fixed groove 16 is provided directly below the cutting frame 2. A cutting pad 17 is embedded in the fixed groove 16. The cutting pad 17 of different hardness is replaced according to the characteristics of the cut paper, which can not only protect the blade 5 but also achieve the best cutting effect. At the same time, a buffer port 18 is provided on the outside of the fixed groove 16, which can facilitate personnel to remove the cutting pad 17 from the fixed groove 16 through the buffer port 18.

[0040] In the embodiment of the present application, an elastic telescopic frame 19 is symmetrically fixed to the outer side of the bottom of the mounting frame 4, and a pressure rod 20 is fixed to the movable end of the bottom of the elastic telescopic frame 19, which can not only position the cutting position, but also prevent the blade 5 from accidentally cutting fingers, etc. The inner side of the pressure rod 20 is made of stainless steel, and the outer side is made of rubber material with greater friction with the paper. By arranging two symmetrically distributed pressure rods 20 on the outer side of the blade 5, and the pressure rod 20 is fixed to the mounting frame 4 through the elastic telescopic frame 19, in the initial state, since the telescopic stroke of the elastic telescopic frame 19 is greater than the height of the blade 5, the pressure rod 20 is located below the blade 5. When the cutting work is in progress, the pressure rod 20 can contact the paper before the blade 5 during cutting, and press and limit the paper to be cut, so as to avoid the paper from shaking when the blade 5 is cutting. At the same time, the setting of the pressure rod 20 can also remind personnel to take their fingers out from under the blade 5 to avoid work injuries.

[0041] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
