[0034] The preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0035] An embodiment of the present invention provides a paper feeding mechanism and a printer. By adaptively changing the width of the paper feeding channel, the paper feeding channel can adapt to the paper feeding of labels of any size, thereby solving the technical problem that it is difficult for printers in the prior art to adapt to the printing of labels of different sizes.

[0036] As Figure 1-2 shown, the paper feeding mechanism of the embodiment of the present invention includes a paper bin 10, a feeding carriage 20, a first stopper 30, a second stopper 40, and a driving unit 50. The paper bin 10 is used to place the labels to be printed; the feeding carriage 20 is fixed to the paper bin 10 and extends in the width direction of the paper bin 10; the first stopper 30 is located inside the paper bin 10 and slidably sleeved on the feeding carriage 20; the second stopper 40 is disposed opposite to the first stopper 30 and slidably connected to the feeding carriage 20, and a paper feeding channel 41 is formed between the second stopper 40 and the first stopper 30; the driving unit 50 is connected to the first stopper 30 and the second stopper 40 and is used to drive the first stopper 30 and the second stopper 40 to slide along the feeding carriage 20.

[0037] Specifically, the paper feeding mechanism is provided with a paper bin 10, a feeding carriage 20, a first stopper 30, a second stopper 40, and a driving unit 50. The paper bin 10 can be used to place the labels to be printed. The feeding carriage 20 is fixed to the paper bin 10 and extends in the width direction of the paper bin 10. Both the first stopper 30 and the second stopper 40 are located inside the paper bin 10 and sleeved on the feeding carriage 20. The first stopper 30 and the second stopper 40 are disposed opposite to each other and form a paper feeding channel 41. The paper feeding channel 41 can allow the label to pass through and limit the two sides of the label. The driving unit 50 is connected to the first stopper 30 and the second stopper 40. By driving the first stopper 30 and the second stopper 40 to slide, the driving unit 50 can adjust the width of the paper feeding channel 41 between the first stopper 30 and the second stopper 40, so that the paper feeding channel 41 can allow labels of any size to pass through, and further enable the printer to adapt to the printing of labels of any size.

[0038] It can be understood that the paper bin 10 can be any bin structure for winding and accommodating labels.

[0039] It can be understood that the feeding carriage 20 can be a slide rail, a slide bar, etc. extending in the width direction of the paper bin 10, which are one or more frame structures for the first stopper 30 and the second stopper 40 to slide. The feeding carriage 20 can be disposed inside or outside the paper bin 10.

[0040] In one of the embodiments, as Figure 2-3As shown, the paper supply carriage 20 includes a first slide bar 21 and a second slide bar 22. The first slide bar 21 and the second slide bar 22 are arranged at intervals along the height direction of the paper bin 10 on the outside of the paper bin 10. The first stopper 30 and the second stopper 40 are respectively sleeved on the first slide bar 21 and the second slide bar 22. Specifically, by providing the first slide bar 21 and the second slide bar 22 that extend in the width direction of the paper bin 10, the first stopper 30 and the second stopper 40 can be slidably connected to the paper supply carriage 20.

[0041] In one embodiment, as Figure 1-2 shown in FIGS. 3 and 4, a paper supply slide hole 11 is provided on the side wall of the paper bin 10. The paper supply slide hole 11 extends in the width direction of the paper bin 10 and is located between the first slide bar 21 and the second slide bar 22. The first stopper 30 and the second stopper 40 are respectively fixed with a first sliding frame 31 and a second sliding frame 42. The first sliding frame 31 and the second sliding frame 42 pass through the paper supply slide hole 11 and are respectively slidably connected to the first slide bar 21 and the second slide bar 22. Specifically, the first stopper 30 and the second stopper 40 can be respectively slidably connected to the first slide bar 21 and the second slide bar 22 through the first sliding frame 31 and the second sliding frame 42. The paper supply slide hole 11 can provide vertical limits for the first sliding frame 31 and the second sliding frame 42 of the first stopper 30 and the second stopper 40, and realize the sliding connection between the first stopper 30 and the second stopper 40 and the bin body, thereby improving the stability when the first stopper 30 and the second stopper 40 slide.

[0042] In this embodiment, there are two paper supply slide holes 11, and the first sliding frame 31 and the second sliding frame 42 respectively slide in the two paper supply slide holes 11.

[0043] In one embodiment, as Figure 2-3 shown, the first sliding frame 31 and the second sliding frame 42 are provided with limit grooves 311, and the side wall of the paper bin 10 is slidably connected to the limit grooves 311. Specifically, by slidably connecting to the limit grooves 311, the side wall of the paper bin 10 can further improve the stability when the first stopper 30 and the second stopper 40 slide, and can realize the limit in the length direction of the first stopper 30 and the second stopper 40, thereby improving the stability of the first stopper 30 and the second stopper 40.

[0044] In this embodiment, the first sliding frame 31 and the second sliding frame 42 are provided with two limit edges, and a limit groove 311 is formed between the two limit edges. The two limit edges are respectively located on the inside and outside of the paper bin 10.

[0045] It can be understood that the driving unit 50 can be any driving device such as a cylinder, a hydraulic cylinder or a lead screw module that can drive the first stopper 30 and the second stopper 40 to slide.

[0046] In one embodiment, as Figure 2-3As shown, the first sliding frame 31 and the second sliding frame 42 are respectively provided with a first rack 312 and a second rack 421. Both the first rack 312 and the second rack 421 extend in the width direction of the paper bin 10. The driving unit 50 includes a driving member (not marked in the figure) and a gear 51. The gear 51 is rotatably connected to the paper bin 10 and is located between the first sliding rod 21 and the second sliding rod 22. The upper and lower sides of the gear 51 are engaged with the first rack 312 and the second rack 421. Specifically, when the driving member drives the gear 51 to rotate, it can drive the first rack 312 and the second rack 421 to approach or move away from each other, thereby driving the first sliding frame 31 and the second sliding frame 42 to approach or move away from each other, realizing the adjustment of the distance between the first stopper 30 and the second stopper 40, and finally realizing the adjustment of the paper feeding channel 41. Through the setting of the above structure, only one driving component needs to be set to drive the first stopper 30 and the second stopper 40 to move synchronously at the same time, thereby simplifying the structure of the paper feeding mechanism and reducing the production cost of the printer.

[0047] In this embodiment, the driving member is a motor.

[0048] In one of the embodiments, as Figure 2-3 shown, a first sliding limit groove 313 is provided on one side of the first sliding frame 31 close to the second sliding rod 22. The first sliding frame 31 is slidably connected to the second sliding rod 22 through the first sliding limit groove 313. Specifically, the first sliding frame 31 can form a sliding fit with the second sliding rod 22 through the first sliding limit groove 313, thereby improving the stability of the first sliding frame 31 and ensuring the stable sliding of the first sliding frame 31.

[0049] In one of the embodiments, as Figure 2-3 shown, a second sliding limit groove 422 is provided on one side of the second sliding frame 42 close to the first sliding rod 21. The second sliding frame 42 is slidably connected to the first sliding rod 21 through the second sliding limit groove 422. Specifically, the second sliding frame 42 can form a sliding fit with the first sliding rod 21 through the second sliding limit groove 422, thereby improving the stability of the second sliding frame 42 and ensuring the stable sliding of the second sliding frame 42.

[0050] In one of the embodiments, as Figure 1 and 4 shown, a feeding chute 12 is provided at the bottom of the paper bin 10. Sliding protrusions 32 are provided at the bottoms of the first stopper 30 and the second stopper 40. The sliding protrusions 32 are slidably connected to the feeding chute 12. Specifically, through the cooperation of the sliding protrusions 32 and the feeding chute 12, the first stopper 30 and the second stopper 40 can be further limited, thereby improving the stability of the first stopper 30 and the second stopper 40 when sliding.

[0051] In one of the embodiments, as Figure 1 and 3As shown, the sliding protrusion 32 is a tip protrusion. By setting the end of the sliding protrusion 32 to a tip structure, the contact area between the sliding protrusion 32 and the paper feeding chute 12 can be reduced, thereby making the sliding of the first stopper 30 and the second stopper 40 smoother.

[0052] The technical solution of the present utility model further provides a printer, including the above paper feeding mechanism. Specifically, by setting this paper feeding mechanism, the printer can be adapted to print labels of any size.

[0053] In this embodiment, the printer is provided with a receiving box, and the paper feeding mechanism is installed in the receiving box.

[0054] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
