Technical Field

[0001] The utility model relates to the technical field of paper cutters, and more specifically, to a paper cutting mechanism of a paper cutter. Background Art

[0002] A paper cutter is a type of cutting machine and is widely used in paper processing. Since printing, packaging, book binding, and other production processes, from cutting materials to printed finished products and cutting of rough copies after binding, require paper cutters for cutting, paper cutters are important equipment for paper processing. Although existing paper cutters can automatically cut paper, in actual use, when workers use paper cutters to cut paper, after cutting one side of the paper, they need to take out the paper, then swap the uncut side of the paper under the cutter, fix the paper, and cut it again. This method is cumbersome and reduces the work efficiency of the workers, so it needs to be improved. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a paper cutting mechanism of a paper cutter, which has the advantage of being convenient for continuously cutting both sides of a paper.

The disc is fixedly mounted on the front end of the round shaft. The round block is fixedly mounted on the front of the disc and the front end of the round block extends to the inside of the square frame. The gasket is fixedly mounted in the middle of the bottom end of the pressure plate. The disc drives the round block to rotate, so that the square frame drives the pressure plate and the gasket to move downward to clamp the paper.

[0012] As a preferred technical solution of the utility model, it also includes:

[0013] The cutting mechanism is arranged above the frame and consists of a cylinder and a cutter;

[0014] The cylinder is fixedly mounted on the middle portion of the top end of the crossbar, and the bottom end of the cylinder passes through the crossbar. The tool is fixedly mounted on the bottom of the cylinder.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, the utility model provides a paper cutting mechanism of a paper cutting machine, comprising:

[0030] A bracket 1, a workbench 2 is provided on the top of the bracket 1, and a frame 3 is provided on the top of the workbench 2;

[0031] A driving mechanism, which is arranged above the frame 3;

[0032] A clamping mechanism, which is arranged below the workbench 2;

[0033] Among them, the driving mechanism includes a first brake motor 7, which is fixedly installed on the top of the right end of the frame 3. The other end of the output shaft of the first brake motor 7 is fixedly sleeved with a rotating shaft 8, and a gear 9 is fixedly installed on the top of the rotating shaft 8. A round rod 4 is fixedly installed between the tops of the inner walls on both sides of the frame 3, and a cross bar 5 is movably sleeved on the outer surface of the round rod 4. A tooth plate 6 is fixedly installed on the right end of the top of the cross bar 5, and the tooth plate 6 is meshed with the gear 9. The rotation of the gear 9 can enable the tooth plate 6 to drive the cross bar 5 to move forward or backward.

[0034] By starting the first brake motor 7, the rotating shaft 8 can drive the gear 9 to rotate. Since the outer surface of the gear 9 is meshed with the outer surface of the toothed plate 6, the rotation of the gear 9 can enable the toothed plate 6 to drive the cross bar 5 to move forward or backward.

[0035] Among them, there are:

[0036] The clamping mechanism is composed of a pressure plate 10, a vertical rod 11, a square frame 12, a second brake motor 13, a circular shaft 14, a circular disc 15, a circular block 16 and a gasket 21;

[0037] The pressure plate 10 is movably mounted on the inner wall of the frame 3. There are two vertical rods 11, which are fixedly mounted on both sides of the bottom of the pressure plate 10 respectively. The bottom end of the vertical rod 11 passes through the workbench 2. The square frame 12 is fixedly mounted on the bottom of the vertical rod 11. The second brake motor 13 is fixedly mounted on the bottom end of the workbench 2. The circular shaft 14 is fixedly sleeved on the other end of the output shaft of the second brake motor 13. The disc 15 is fixedly mounted on the front end of the circular shaft 14. The round block 16 is fixedly mounted on the front of the disc 15 and the front end of the round block 16 extends to the inside of the square frame 12. The gasket 21 is fixedly mounted in the middle of the bottom end of the pressure plate 10. The disc 15 drives the round block 16 to rotate, so that the square frame 12 drives the pressure plate 10 and the gasket 21 to move downward to clamp the paper.

[0038] By starting the second brake motor 13, the circular shaft 14 can drive the circular disc 15 and the circular block 16 to rotate, thereby squeezing the inner wall of the square frame 12, and then the square frame 12 can drive the vertical rod 11, the pressure plate 10 and the gasket 21 to clamp and fix the paper.

[0039] Among them, also include:

[0040] The cutting mechanism is arranged above the frame 3 and consists of a cylinder 17 and a cutter 18;

[0041] The cylinder 17 is fixedly mounted at the middle of the top end of the crossbar 5 and the bottom end of the cylinder 17 passes through the crossbar 5 , and the tool 18 is fixedly mounted at the bottom of the cylinder 17 .

[0042] By activating the air cylinder 17 , the cutter 18 can be moved downward, thereby being able to cut the paper.

[0043] Guide rods 19 are fixedly installed on both sides of the top of the cutter 18 , and the tops of the guide rods 19 pass through the cross bar 5 .

[0044] The design of the guide rod 19 can effectively limit the position of the tool 18, thereby making the tool 18 more stable when moving up and down.

[0045] Among them, fixed blocks 20 are fixedly installed on both sides of the top of the workbench 2. There are two fixed blocks 20, and the two fixed blocks 20 have the same size.

[0046] The design of the fixing block 20 can facilitate the staff to align the paper, thereby improving the cutting quality.

[0047] The width of the gasket 21 is the same as that of the pressing plate 10 , and the gasket 21 is made of rubber.

[0048] The soft nature of rubber can provide a certain cushioning effect when clamping paper, thereby avoiding indentations on the paper that affect its quality.

[0049] The outer surface of the round block 16 is slidably connected to the inner wall of the square frame 12 , and both the outer surface of the round block 16 and the inner wall of the square frame 12 are smooth.

[0050] The outer surface of the round block 16 and the inner wall of the square frame 12 are both smooth, so that the round block 16 can slide more smoothly inside the square frame 12.

[0051] The working principle and use process of this utility model:

[0052] First, the staff places the paper to be cut on the top of the workbench 2 and aligns it, and then starts the second brake motor 13. Due to the operation of the second brake motor 13, the circular shaft 14 will drive the circular disc 15 and the circular block 16 to rotate. Due to the rotation of the circular block 16, the inner wall of the square frame 12 will be squeezed, so that the square frame 12 can drive the vertical rod 11, the pressure plate 10 and the gasket 21 to move downward, and then the gasket 21 can press the paper tightly.

[0053] After the paper is fixed, the staff can then start the first brake motor 7. Due to the operation of the first brake motor 7, the rotating shaft 8 can drive the gear 9 to rotate. Since the outer surface of the gear 9 is meshed with the outer surface of the tooth plate 6, the rotation of the gear 9 can enable the tooth plate 6 to drive the cross bar 5 to move forward or backward, thereby enabling the tool 18 to move forward or backward. After adjusting the position of the tool 18, the staff can start the cylinder 17. Due to the operation of the cylinder 17, the tool 18 will move downward to cut the paper. When it is necessary to cut the other side of the paper, the staff can start the first brake motor 7 again to move the tool 18 to the top of the other side of the paper, and then start the cylinder 17 again to cut the paper, thereby achieving the effect of continuous cutting on both sides of the paper and improving the work efficiency of the staff.
