The paper feeding structure includes a first paper feeding assembly, a second paper feeding assembly and a paper feeding unit 3. The first paper feeding assembly is connected to the first unwinding structure 1. The second paper feeding assembly is connected to the second unwinding structure 2. The first paper feeding assembly is used to feed the paper from the first unwinding structure 1 to the paper feeding unit 3. The second paper feeding assembly is used to feed the paper from the second unwinding structure 2 to the paper feeding unit 3.

[0067] In this embodiment, the first paper feeding assembly includes a first driving wheel 4, a first driven wheel 5 and a first paper feeding track 6. The first driving wheel 4 and the first driven wheel 5 are arranged at one end of the first paper feeding track 6. The first driving wheel 4 and the first driven wheel 5 are used to clamp and feed the paper from the first unwinding structure 1 to the paper feeding unit 3.

[0068] In this embodiment, the first paper feeding assembly further includes a first detection unit. The first detection unit is used to detect the paper on the first paper feeding track 6.

[0069] In this embodiment, the first detection unit comprises a first sensor 7 and a second sensor 8; the first sensor 7 is used to detect whether the paper on the first paper feed track 6 passes through the head; the second sensor 8 is used to detect whether the paper on the first paper feed track 6 is in place.

[0070] In this embodiment, the second paper feed assembly comprises a second driving wheel 9, a second driven wheel 10 and a second paper feed track 11; the second driving wheel 9 and the second driven wheel 10 are arranged at one end of the second paper feed track 11; the second driving wheel 9 and the second driven wheel 10 are used to clamp the paper from the second unwinding structure 2 and feed it to the paper feed unit 3.

[0079] Then, the control center controls the second pressure roller assembly 19 to drive the second driven roller 10 to approach the second driving roller 9, and controls the second motor 15 to work, and the second unwinding structure 2 starts to supply paper. The paper supply process is the same as that of the first unwinding structure 1.

[0080] The third sensor 12 has the same effect as the first sensor 7, and the fourth sensor 13 has the same effect as the second sensor 8.

[0081] The embodiment can realize automatic paper changing process, and reduces downtime waiting time. When the second unwinding structure 2 supplies paper, workers can check the first unwinding structure 1 to see whether there is a paper jam or no paper phenomenon, and the second unwinding structure 2 is in working state during maintenance or paper changing, and does not affect the normal paper feeding process.

[0082] When the paper of the second unwinding structure 2 is used up, the paper of the first unwinding structure 1 is also replenished, so that the first unwinding structure 1 is switched to supply paper.

[0083] The embodiment has simple structure, convenient operation, does not affect normal paper supply, greatly reduces downtime, and greatly improves work efficiency.

[0084] It should be noted that the above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
