Optionally, the number of the supporting frames 820 and the number of the pressing wheels 830 are multiple, the supporting frames 820 are sequentially arranged along the axial direction of the supporting shaft 810, and one pressing wheel 830 is correspondingly installed on one supporting frame 820.

As for the pinch roller driving module 900, please refer to fig. 7 and 8, it is connected to the supporting shaft 810, and is used for driving the supporting shaft 810 to rotate so as to make each pinch roller close to the conveying roller 700 at a proper time, and further press the printing medium onto the conveying roller, thereby preventing the printing medium from swinging during the movement process; the pinch roller driving module 900 is further configured to drive the supporting shaft 810 to rotate so that each pinch roller is timely away from the conveying roller 700, and thus the front end of the printing medium is allowed to pass through the conveying roller 700 and abut against the front barrier 500, thereby completing the positioning process. In this embodiment, the pressure wheel driving module 900 includes a pressure wheel cylinder 910 and a swing arm 920; wherein, the body of the pinch roller cylinder 910 is rotatably mounted to the mounting beam 610, i.e. indirectly mounted to the base 100; one end of the swing arm 920 is rotatably connected with the telescopic rod of the pinch roller cylinder 910, and the other end is fixedly connected with the support shaft 810. Then, the main body of the pressing wheel cylinder 910, the telescopic rod of the pressing wheel cylinder 910, the swing arm 920 and the mounting beam 610 (or the base) together form a crank rocker mechanism, that is, the telescopic rod of the pressing wheel cylinder 910 is controlled to extend and retract, so that the supporting shaft 810 can be driven to rotate, and then the pressing wheels 830 are driven to be close to or far away from the conveying roller 700. It can be understood that, in other embodiments of the present invention, the pressing wheel driving module may also be other structures such as a motor, as long as it can drive the supporting shaft to rotate, which is not described in detail herein.

Next, taking a conveying manner in which the double printing mediums travel side by side as an example, the operation process of the conveying apparatus provided by the embodiment of the present invention will be briefly described with reference to the drawings.

In the initial state, the first axis Y is parallel to the width direction, the front baffle 500 is close to the base 100, the conveying roller driving module is in the non-operating state, and the pressing wheel 830 is far away from the conveying roller 700.

When the printing medium needs to be conveyed, the turnover power mechanism 340 is started to enable each balance 211 to rotate around the first axis Y; simultaneously, the two deflection power mechanisms 231 in the two deviation-correcting conveying modules 200 are started to make the balance wheels 211 of the two deviation-correcting conveying modules 200 deflect reversely, and the balance wheels 211 in each deviation-correcting conveying module 200 gradually approach the end baffle 400 adjacent to the balance wheels along the conveying direction X. Then, two printing mediums are respectively placed on the balance set 210 of the two deviation-correcting conveying modules 200, and the two printing mediums are driven by the balance 211 and are abutted by the end baffle 400 and the front baffle 500 to complete the positioning process. Then, the pinch roller driving module 900 drives each pinch roller 830 to approach the conveying roller 700 and press the printing medium against the conveying roller 700. Next, the front barrier driving module 600 drives the front barrier 500 away from the base 100, the conveying roller driving module drives the conveying roller 700 to rotate, and the printing medium is driven by the conveying roller 700 to leave the conveying device. Then, the front barrier driving module 600 drives the front barrier 500 to approach the base 100, the pinch roller driving module 900 drives each pinch roller 830 to move away from the conveying roller, and the conveying roller driving module stops operating.

The principle of conveying a single printing medium is different from that of the double printing medium in that only the swing power mechanism 231 in one deviation-correcting conveying module 200 needs to be started, or the swing power mechanisms 231 in the two deviation-correcting conveying modules 200 are started simultaneously, and the swing wheels in the two deviation-correcting conveying modules 200 are ensured to have the same deflection direction, and other operation actions are basically the same as those of the double printing medium, which is not described herein again.

The embodiment of the utility model provides a conveyor includes base 100, the transport module 200 of rectifying, turnover drive module 300, both ends baffle 400, preceding baffle 500 and preceding baffle drive module 600. The deviation rectifying conveying module 200 includes a balance wheel set 210, a mounting frame set 220, and a deviation driving module 230, wherein the balance wheel set 210 includes a plurality of balance wheels 211 arranged at intervals along the conveying direction X. The epicyclic driving module 300 is used for driving each balance 211 to rotate around the first axis Y so as to enable the medium carried on the balance set 210 to move along the conveying direction X; the deflection driving module 230 is used for driving each balance 211 in the oscillating wheel set 210 to deflect around the second axis Z, so that the medium is continuously close to the end baffle 400 in the process of advancing to the front baffle 500, and the medium is positioned under the joint abutting action of the front baffle 500 and the end baffle 400.

Compare with conveyor on the existing market, this conveyor passes through the beat action of balance 211 and makes the medium accomplish the location process, and need not to newly increase the neat module of independent bat in addition in the base top, so the embodiment of the utility model provides a conveyor is favorable to the miniaturized demand of firm.

It should be understood that even though there are multiple sets of the balance sets 210 in the same deviation rectification conveying module in the present embodiment, in other embodiments of the present invention, there may also be one set of the balance sets 210 in the same deviation rectification conveying module, and accordingly, there is one first connecting arm 2341, and at this time, the connecting rod 233 may be indirectly connected to the first connecting arm 2341 through the second connecting arm 2342, or may be directly connected to the first connecting arm 2341 in a rotating manner.

Based on the same inventive concept, the utility model also provides a printing device, this printing device includes the conveyor that the above-mentioned embodiment provided, so this printing device also can effectively solve the technical problem that traditional printing device is unfavorable for the miniaturization.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; within the idea of the invention, also technical features in the above embodiments or in different embodiments can be combined, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
