The frame 2 includes a frame facade 3, a frame column 4, a frame upper platform 5 and a frame lower platform 6. The motor 1 is fixed on the frame facade 3 of the frame 2, and also includes a waste storage bin 17. The waste storage bin 17 is arranged at the lower part of the frame 2. It also includes a transmission system, a slide 11, a cutter 13, a column 15, and a spring 16. The upper and lower parts of the column 15 are respectively connected to the frame upper platform 5 and the frame lower platform 6 of the frame 2. The slide 11 passes through the column 15 and is located between the frame upper platform 5 and the frame lower platform 6. The spring 16 is arranged at the lower part of the slide 11 and on the frame lower platform 6. The cutter 13 is vertically fixed to the slide 11, and the transmission system drives the slide 11 to move downward.

[0044] The upper and lower parts of the upright posts 15 are respectively connected to the upper platform 5 and the lower platform 6 of the frame 2, so that a stable track for the slide 11 to move up and down is provided.

[0045] The cutter 13 is fixed vertically in the slide 11. Figure 1 It can be seen that the blade of the cutter 13 faces downward. The downward movement of the slide 11 will inevitably drive the cutter 13 to cut the paper material.

[0046] The motor 1 is fixed to the frame vertical surface 3 of the frame 2 by means of screws.

[0047] As a preferred embodiment, Figure 1 , Figure 4 , Figure 6 As shown, the transmission system includes a driving wheel 7, a driven wheel 8, and a cam 9. The driving wheel 7 is connected to the output shaft end of the motor 1, and the driven wheel 8 and the cam 9 are connected through a rotating shaft 10. The driven wheel 8 and the rotating shaft 10 are concentric, and the hole of the cam 9 for the rotating shaft 10 to pass through is not in the center of the cam 9. The driven wheel 8 and the cam 9 are fixedly connected, the driving wheel 7 is meshed with the driven wheel 8, and both ends of the rotating shaft 10 are fixed on the frame 2, and the cylindrical surface of the cam 9 is in contact with the slide 11.

[0048] The driven wheel 8 and the cam 9 are fixedly connected, which can be welded or pinned, to ensure that the two rotate synchronously with the driving wheel 7. There is a certain transmission ratio between the driving wheel 7 and the driven wheel 8 to ensure smooth cutting.

[0049] The hole of the cam 9 for the rotating shaft 10 to pass through is arranged to ensure that when the farthest end column of the cam 9 rotates downward to the lowest point, the slide 11 is driven to the cutter 13 to complete the cutting of the paper material.

[0050] like Figure 1 , Figure 6 As shown, the frame 2 is provided with holes for fixing the two ends of the rotating shaft 10 .

[0051] As a preferred embodiment, Figure 1 , Figure 6 As shown, the slide 11 is provided with a mounting hole for the cutter 13 , the lower portion of the mounting hole matches the inclined surface of the blade of the cutter 13 , and the lower opening of the mounting hole is smaller than the upper opening.

[0052] As a preferred embodiment, Figure 1 , Figure 6 As shown, a cutter cover plate 19 is provided at the position where the cutter 13 mounting hole is provided on the slide 11 , and the cutter cover plate 19 is fixed to the upper surface of the slide 11 by screws 20 to fix the cutter 13 .

[0053] As a preferred embodiment, Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the contact between the cylindrical surface of the cam 9 and the slide 11 means that the cylindrical surface of the cam 9 is in contact with the cutter cover plate 19, and the slide 11 is driven to move downward during the rotation of the cam 9.

[0054] As a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, a mounting hole is provided at the lower part of the lower platform 6 of the frame corresponding to the cutter 13, and a protective gasket 14 is installed.

[0055] As a preferred embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, a protective gasket bracket 22 is provided at the lower part of the protective gasket 14 , and the protective gasket bracket 22 has a corresponding threaded hole. The adjusting screw 21 is used to adjust the height of the protective gasket 14 up and down through the threaded hole of the protective gasket bracket 22 .

[0056] The protective gasket 14 is elastic to prevent damage to the cutter 13. The adjusting screw 21 is used to slightly adjust the height of the protective gasket 14 through the threaded hole of the protective gasket bracket 22 to avoid errors and ensure smooth cutting and flat cutting surface.

[0057] As a preferred embodiment, Figure 4 As shown, a sheath 23 is provided at the contact point between the column 15 and the slide 11 .

[0058] The sheath 23 is wear-resistant. Of course, the sheath 23 is sleeved on the outer surface of the column 15.

[0061] When the micro switch 18 detects that the light paper material entering from the inlet and outlet 12 reaches the preset position, the motor 1 starts, and the power is transmitted to the slide 11 through the driving wheel 7, the driven wheel 8, and the cam 9, driving the slide 11 to move downward to cut the paper material.

[0062] After the cutting is completed, the motor 1 drives the driven wheel 8 and the cam 9 to continue to rotate, and the compressed spring 16 drives the slide 11 downward and the cutter 13 upward.

[0063] The rack facade 3, rack columns 4, rack upper platform 5 and rack lower platform 6 of the rack 2 are an integrated structure.

[0064] The frame 2 is made of aluminum, but can also be made of other materials with better performance.

[0066] As a preferred embodiment, Figure 1 , Figure 2 , Figure 5 , Figure 7 As shown, the number of the columns 15 is 2-4.

[0067] Of course, the number of the column 15 can also be one. If the number of the column 15 is one, the stability of cutting paper materials is not good.

[0068] Of course, the device can also be used to cut other materials comparable to paper materials.
