Then, the relative position of the limiting baffle and the cutting blade is adjusted. The operator rotates the baffle screw, and the baffle screw drives the limiting baffle to slide along the groove of the baffle slide through the sliding bracket. Then, the operator pushes the paper to fit one end of the paper against the outer wall of the limiting baffle, realizing the positioning operation of the paper cutting length.

[0025] Based on the above structure, the rotation of the limiting screw 8 drives the two sets of limiting guide grooves 10 to slide synchronously through the connecting plate 9. The sliding of the limiting guide groove 10 drives the sliding block 13 at the top of the connecting seat 12 to slide along the groove of the limiting slide groove 14 through the connecting column 11. The sliding block 13 drives the limiting block 15 to fit against both sides of the paper, realizing the centering and limiting operation of the paper and preventing the paper from shifting during cutting.

[0026] In one embodiment, the limiting guide groove 10 is inclined.

[0027] In this embodiment, by setting an inclined limiting guide groove 10, it is beneficial for the limiting guide groove 10 to slide through the connecting column 11 to drive the sliding block 13 at the top of the connecting seat 12 to slide along the groove of the limiting slide groove 14, thereby realizing the control operation of the sliding block 13 sliding.

[0028] In one embodiment, two sets of sliding blocks 13 are provided, and the two sets of sliding blocks 13 are equidistantly distributed along the outer wall of the connecting seat 12.

[0030] In one embodiment, the sliding block 13 forms a sliding structure with the limiting guide groove 10 and the connecting post 11 and the limiting slide groove 14.

[0031] In this embodiment, the limiting guide groove 10 slides through the connecting column 11 to drive the sliding block 13 at the top of the connecting seat 12 to slide along the groove of the limiting slide groove 14. The sliding block 13 drives the limiting block 15 to fit against both sides of the paper, thereby achieving the centering and limiting operation of the paper and preventing the paper from shifting during cutting.

[0033] In this embodiment, the operator overcomes the elastic force of the spring 23 to drive the push block 22 to slide. The sliding of the push block 22 causes the limiting push plate 24 to fit tightly against one side of the paper, thereby achieving the flattening operation of the paper end face. Then, the relative position of the limiting baffle 20 and the cutting blade 6 is adjusted. The operator rotates the baffle screw 17, and the baffle screw 17 drives the limiting baffle 20 to slide along the groove of the baffle slide groove 19 through the sliding bracket 18.

[0037] In this embodiment, the sliding push block 22 drives the limiting push plate 24 to fit tightly against one side of the paper, thereby achieving the flattening operation of the paper end face.

[0038] In this embodiment of the automatic paper cutter with multi-point limiting, the operator first places the paper on the workbench 1. Then, the operator rotates the limiting screw 8. The rotation of the limiting screw 8 drives the two sets of limiting guide grooves 10 to slide synchronously through the connecting plate 9.

[0039] Then, the worker overcomes the elastic force of the spring 23 to drive the push block 22 to slide. The sliding of the push block 22 causes the limiting push plate 24 to fit tightly against one side of the paper, realizing the flattening operation of the paper end face. Next, the relative position of the limiting baffle 20 and the cutting blade 6 is adjusted. The worker rotates the baffle screw 17. The baffle screw 17 drives the limiting baffle 20 to slide along the groove of the baffle slide groove 19 through the sliding bracket 18. Then, the worker pushes the paper, making one end of the paper fit against the outer wall of the limiting baffle 20, realizing the positioning operation of the paper cutting length.
