[0036] When the printer completes printing and the printing paper monitoring module detects that the printing paper is not taken away within a set time, the recycling rubber roller group 161 is triggered to reverse to recycle the printing paper into the recycling cavity 162.

[0037] The recycling assembly provided by the embodiment has a simple structure and is convenient to recycle.

[0038] Further, the recycling cavity 162 is connected with a paper shredding device.

[0039] In specific implementation, the recycling cavity 162 is connected with a paper shredding device (not shown in the figure), and the paper shredding device is used to shred the recycled printing paper.

[0040] Further, one side of the recycling rubber roller group 161 is provided with a first guide structure 163.

[0041] In particular implementation, as shown in Figure 2 , the first guiding structure 163 is arranged on one side of the recycling rubber roller group 161. The cross-sectional shape of the first guiding structure 163 includes but is not limited to an arc shape, and the concave surface of the arc shape faces the side of the recycling rubber roller group 161. Through the guidance of the first guiding structure 163, the recycled printing paper enters the recycling cavity 162.

[0042] Further, the anti-pulling assembly 13 includes an anti-pulling rubber roller group 131, a driving device, a gap 132, and a storage space 133, wherein:

[0043] The anti-pulling rubber roller group 131 is arranged at the paper outlet 12; the anti-pulling rubber roller group 131 is connected with the driving device;

[0044] The paper path between the anti-pulling rubber roller group 131 and the printing assembly 11 is provided with the gap 132; the gap 132 is connected with the storage space 133; the storage space 133 can accommodate the printing paper 20 arched from the gap 132.

[0045] In particular implementation, as shown in Figure 1 , Figure 2 and Figure 3 , the anti-pulling assembly 13 includes an anti-pulling rubber roller group 131, a driving device, a gap 132, and a storage space 133, wherein:

[0046] The anti-pulling rubber roller group 131 is arranged at the paper outlet 12; the anti-pulling rubber roller group 131 is connected with the driving device; the driving device is a motor or the like for driving at least one rubber roller (such as a rubber roller) in the anti-pulling rubber roller group 131 to rotate;

[0047] The paper path between the anti-pulling rubber roller group 131 and the printing assembly 11 is provided with the gap 132; the length of the gap 132 perpendicular to the paper feeding direction needs to be greater than the width of the printing paper 20; the gap 132 is connected with the storage space 133; the storage space 133 can accommodate the printing paper 20 arched from the gap 132.

[0048] In operation, the printing paper 20 is sent to the printing assembly 11 by the printer body 10 for printing, and the front end of the printed printing paper 20 is sent to the anti-pulling rubber roller group 131 and is blocked by the anti-pulling rubber roller group 131. At this time, when the paper continues to be sent to the anti-pulling rubber roller group 131, the printing paper 20 is arched from the gap 132 to the storage space 133 (as shown in Figure 3 ) until the printing is completed; when the printing is completed, the anti-pulling rubber roller group 131 is started, the anti-pulling rubber roller group 131 clamps the front end of the printing paper 20, and continues to move the printing paper 20 to the side of the paper outlet 12 until the printed printing paper 20 is sent out.

[0049] The anti-pulling assembly 13 composed of the anti-pulling rubber roller group 131, the driving device, the gap 132 and the storage space 133 in the embodiment can realize the effect of storing the printing paper 20 during printing and outputting the printing paper 20 after printing, and has a simple structure and is practical.

[0050] Preferably, the anti-pulling rubber roller group 131 is provided with a printing paper detection sensor. When the printing paper detection sensor detects that the front end of the printing paper 20 enters or approaches the anti-pulling rubber roller group 131 during printing, the anti-pulling rubber roller group 131 starts to rotate and clamps the front end of the printing paper 20. The printing paper detection sensor includes but is not limited to the existing thermistor sensor, reed switch sensor, photoelectric sensor and the like. The detection of whether the printing paper exists or not by the printing paper detection sensor is a common technology in the field of printers, and the structure and principle for realizing the detection of the printing paper will not be described herein.

[0051] In specific implementation, as shown in the figure, Figure 2 a cutter assembly 14 is arranged between the printing assembly 11 and the anti-pulling assembly 13. The cutter assembly 14 is used for cutting the printing paper in a roll or in a continuous form. The cutter assembly 14 includes but is not limited to the existing integrated cutter and split cutter for cutting the printing paper.

[0052] Further, the anti-pulling rubber roller group 131 of the anti-pulling assembly 13 and the recycling rubber roller group 161 of the recycling assembly are the same rubber roller group.

[0053] In specific implementation, as shown in the figure, Figure 2 the recycling assembly and the anti-pulling assembly 13 have substantially the same structure as in the above embodiment, and the difference lies in that the anti-pulling rubber roller group 131 of the anti-pulling assembly 13 and the recycling rubber roller group 161 of the recycling assembly are the same rubber roller group. That is, the anti-pulling rubber roller group 131 and the recycling rubber roller group 161 are the same rubber roller group. The printing paper 20 enters from the paper inlet 15, is printed by the printing assembly 11, then passes through the cutter assembly 14, and the front end of the printing paper 20 continues to move to the side of the paper outlet 12 in the paper path. When the front end of the printing paper 20 is blocked by the anti-pulling rubber roller group 131 (i.e., the recycling rubber roller group 161), the printing rubber roller of the printing assembly 11 continues to feed the paper, the middle part of the printing paper 20 is arched at the gap 132, and after the printing is completed and the printing paper is cut by the cutter assembly 14, the anti-pulling rubber roller group 131 (i.e., the recycling rubber roller group 161) starts to feed the printing paper to the paper outlet 12, and finally the anti-pulling rubber roller group 131 (i.e., the recycling rubber roller group 161) clamps the end of the printing paper 20.

[0054] When the printing paper 20 is not taken away within a set time, the anti-pulling rubber roller group 131 (i.e., the recycling rubber roller group 161) reverses to recycle the printing paper 20 into the recycling cavity 162.

[0055] In this embodiment, by sharing a set of rubber rollers, the number of parts used is reduced, thereby reducing the production cost of printing paper.

[0056] Furthermore, the notch 132 is provided with an arc-shaped second guide structure 1321.

[0057] In practice, the notch 132 is provided with an arc-shaped second guide structure 1321. The arc-shaped structure can better guide the protective layer of the printing paper 20 into the storage space 133.

[0058] Furthermore, a movable guide plate 134 is provided on the side of the notch 132 near the printing assembly 11.

[0059] In specific implementation, such as Figure 2 , Figure 3 As shown, a movable guide plate 134 is provided on the side of the notch 132 near the printing assembly 11; the movable guide plate 134 is provided with a connecting part 1341, which is movably connected to the side wall of the printer body 10 housing via the connecting part 1341. When the middle of the printing paper 20 is inserted into the storage space 133, the free end of the movable guide plate 134 is arched by the printing paper 20, which can increase the width of the notch 132 in the paper feeding direction, so that the middle of the printing paper 20 can enter the storage space 133 and exit more smoothly.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
