[0061] Specifically, in this embodiment, the central axis of the safety light curtain 19 coincides with the central axis of the winding roller 20.

[0062] Specifically, in this embodiment, the winding roller mechanism includes a winding roller 20, a right winding fixed seat 21, a left winding fixed seat 3, and a winding motor 15; a printing paper winding baffle 16 is provided on the winding roller 20, and the printing paper winding baffle 16 is a perforated circular plate, which is used to block the printing paper during the printing paper winding process; the right winding fixed seat 21 penetrates through the right mounting plate 14, the right end of the winding roller 20 is connected to the winding motor 15 through a coupling, and the winding motor 15 is fixed to the outside of the right mounting plate 14 by bolts.

[0064] Specifically, in this embodiment, the pressure roller 22 is a hollow roller, and its surface is a rubber coating.

[0065] During the test, since the printing paper is smooth and the driving friction is relatively small, it is easy to cause deviation during the winding process. The rubber roller can absorb and reduce the vibration generated during machine operation, thereby reducing damage to the paper. The friction coefficient of the rubber roller is moderate, which can provide sufficient friction to keep the paper wound stably without damaging the paper. Therefore, the pressure roller is a hollow roller, and the surface coating is rubber, which reduces the weight of the pressure roller while increasing the friction between the printing paper and the pressure roller, ensuring the stability of the printing paper winding.

[0066] Specifically, in this embodiment, the safety grating 19 is respectively connected to the transverse movement motor 18, the pressure roller adjustment motor 11, and the winding motor 15.

[0067] Specifically, in this embodiment, the winding guiding device further includes a push switch for emergency stop of the motor; the push switch includes a first switch connected to the pressure roller adjustment motor 11, a second switch connected to the winding motor 15, and a third push switch connected to the transverse movement motor 18.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
