[0002] Printing technology plays an important role in various fields, bringing great convenience and promotion to people's lives and social development. Common printing technologies require the use of printing paper, and the production of printing paper requires steps such as shredding, steaming, impurity removal, papermaking, water squeezing, drying and cutting. Among them, paper cutting requires the use of a paper slitting device.

[0003] Existing paper slitting devices usually place a heavy object on the paper to fix the paper, and then use a slitting cutter to slit the paper. Then the staff takes the slit printing paper away for subsequent slitting.

[0004] The existing paper slitting device has the following problems: when slitting paper, the unevenness of the paper and the instability of the slitting tool will cause the paper cut to be uneven and cause errors, and manual labor is required to transport the paper forward. After the slitting is completed, paper scraps will be generated, and manual cleaning is time-consuming and laborious. For this reason, we propose a slitting device for printing paper production.

Then the staff controls the motor 13 through the single chip computer 17 to rotate the active dial 12. When the round pin 121 on the active dial 12 enters the radial groove 112 of the driven groove wheel 11, the driven groove wheel 11 does not move because the inner concave locking arc 111 of the driven groove wheel 11 is stuck by the outer convex locking arc 122 of the active dial 12. When the active dial 12 is rotated until the round pin 121 enters the radial groove 112 of the driven groove wheel 11, the driven groove wheel 11 is driven by the round pin 121 to rotate. , and when the round pin 121 leaves the radial groove 112 on the other side, the concave locking arc 111 of the driven groove wheel 11 is caught by the convex locking arc 122 of the active dial 12, and the driven groove wheel 11 is stationary again until the round pin 121 enters another radial groove 112 again, and the above movement is repeated.
