[0022] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0023] like Figure 1-4 In an embodiment of the present application, the present application provides an intermittent paper picking mechanism, including: a mounting assembly 10, a driving assembly 20, an elastic support assembly 30, a driving gear assembly 40, a driven gear assembly 50 and a paper picking assembly 60, and each part is described in detail below.

[0024] like Figure 1-4 In an embodiment of the present application, an intermittent paper picking mechanism provided by the present application includes:

[0025] The mounting assembly 10 is used to mount the driving gear assembly 40 on the mounting surface; the mounting assembly 10 is disposed on the mounting surface;

[0026] A driving assembly 20, used to drive the driving gear assembly 40 to move on the mounting assembly 10; the driving assembly 20 is disposed on the mounting surface and close to the first end of the mounting assembly 10;

[0027] An elastic support assembly 30, used for elastically supporting the driving gear assembly 40 to move on the mounting assembly 10; the elastic support assembly 30 is disposed at the second end of the mounting assembly 10;

[0028] The driving gear assembly 40 is used to be controlled by the driving assembly 20 to move; the driving gear assembly 40 is disposed on the mounting assembly 10 and is intermittently connected to the driving assembly 20;

[0029] The passive gear assembly 50 is used to be controlled by the active gear assembly 40 to rotate; the passive gear assembly 50 is disposed on the mounting surface and is intermittently connected to the active gear assembly 40;

[0030] The paper picking assembly 60 is used to be controlled by the passive gear assembly 50 to rotate and pick up paper; the paper picking assembly 60 is disposed on the mounting surface and is intermittently connected to the passive gear assembly 50 .

[0031] When the intermittent paper picking mechanism is used to complete the paper feeding work inside the printer, the mounting assembly 10 is set on the mounting surface of the printer, the driving assembly 20 is connected to the controller of the printer, the active gear assembly 40 is connected to the driving motor on the printer, and the paper picking assembly 60 is close to the paper bin of the printer, and the paper in the paper bin contacts the paper picking assembly 60. When paper picking is required, the controller on the printer sends a control signal to the driving assembly 20, and the driving assembly 20 drives the active gear assembly 40 to move toward the passive gear assembly 50 on the mounting assembly 10. When the active gear assembly 40 moves to the first position on the mounting assembly 10, the active gear assembly 40 is connected to the passive gear assembly 50. At this time, the driving motor on the printer works and drives the active gear assembly 40 to rotate, and then the active gear assembly 40 drives the passive gear assembly 50 to rotate; when the passive gear assembly 50 rotates to a preset angle, the passive gear assembly 50 is connected to the paper picking assembly 60, and at this time, the paper picking assembly 60 rotates and outputs the paper in the paper bin. When paper picking is not needed, the controller on the printer sends a control signal to the driving assembly 20, the driving assembly 20 stops driving the driving gear assembly 40, the elastic support assembly 30 drives the driving gear assembly 40 to reset and separate from the passive gear assembly 50, the passive gear assembly 50 loses the driving force and stops driving the paper picking assembly 60 to rotate, and the paper picking assembly 60 stops picking paper. The driving assembly 20 and the elastic support assembly 30 respectively press against both sides of the driving gear assembly 40, thereby limiting its movement on the mounting assembly 10.

[0032] like Figure 1-4 In the embodiment of the present application, the mounting assembly 10 includes: a mounting shaft 11, and the mounting shaft 11 is arranged on the mounting surface. Specifically, the mounting shaft 11 is arranged on the mounting surface of the inner wall of the printer.

[0033] like Figure 1-4 In the embodiment of the present application, the driving assembly 20 includes: a support plate 21, a baffle 22, a guide rod 23, a buckle 24, an electromagnet 25, a spring 26, a support rod 27 and a retaining ring 28, wherein the first end of the guide rod 23 is connected to the baffle 22 and the second end passes through the through hole on the support plate 21, the buckle 24 is fastened to the second end of the guide rod 23, the electromagnet 25 is arranged on the support plate 21 and is opposite to the baffle 22, the first end of the support rod 27 is connected to the support plate 21 and the second end passes through the mounting surface, the retaining ring 28 is fastened to the second end of the support rod 27, the baffle 22 is close to the first end of the mounting shaft 11 in the mounting assembly 10, and is tightly against the driving gear assembly 40, the spring 26 is sleeved on the guide rod 23, and the two ends are respectively tightly against the support plate 21 and the baffle 22.

[0034] In the embodiment of the present application, the second end of the support rod 27 is inserted into the inner wall mounting surface of the printer, and the retaining ring 28 is fastened to the second end of the support rod 27 and pressed against the inner wall, thereby preventing the support rod 27 from falling off the mounting surface. The support plate 21 is close to the inner wall of the printer, and the baffle 22 is pressed against the active gear assembly 40. The electromagnet 25 is connected to the controller of the printer. When in a natural state, the electromagnet 25 has no magnetism, and the two sides of the active gear assembly 40 are pressed against the baffle 22 and the elastic support assembly 30 respectively, and are in a balanced state, and the active gear assembly 40 and the passive gear assembly 50 are separated from each other; when paper needs to be taken, the controller sends a signal to the electromagnet 25, the electromagnet 25 generates magnetism, and attracts the baffle 22 to move toward the support plate 21, at which time the active gear assembly 40 moves to the first position under the elastic support of the elastic support assembly 30 and meshes with the passive gear assembly 50. When there is no need to take paper, the controller sends a signal to the electromagnet 25, the electromagnet 25 loses its magnetism, the baffle 22 loses the adsorption effect of the electromagnet 25, and moves away from the support plate 21 to the second position under the elastic action of the spring 26. At this time, the driving gear assembly 40 and the driven gear assembly 50 are separated from each other.

[0035] like Figure 1-4In the embodiment of the present application, the elastic support component 30 includes: a limit ring 31 and a clamping spring 32. A baffle 12 is provided on the second end of the mounting shaft 11. The limit ring 31 is sleeved on the second end of the mounting shaft 11 in the mounting component 10 and is clamped against the baffle 12. The clamping spring 32 is sleeved on the mounting shaft 11, and its two ends are respectively clamped against the driving gear component 40 and the limit ring 31. When the driving gear component 40 moves to the first position on the mounting shaft 11, the clamping spring 32 and the baffle 22 jointly clamp the driving gear component 40, stably keeping it at the first position, and stably meshing with the passive gear component 50; when the driving gear component 40 moves to the second position on the mounting shaft 11, the clamping spring 32 and the baffle 22 jointly clamp the driving gear component 40, stably keeping it at the second position, and separating from the passive gear component 50.

[0036] like Figure 1-4 In the embodiment of the present application, the active gear assembly 40 includes: a driving gear 41, the driving gear 41 is sleeved on the mounting shaft 11 in the mounting assembly 10, and is respectively pressed against the baffle 22 in the driving assembly 20 and the pressing spring 32 in the elastic support assembly 30. When the driving gear 41 moves along the mounting shaft 11 to a first position, the driving gear 41 is meshed with the passive gear assembly 50; when the driving gear 41 moves along the mounting shaft 11 to a second position, the driving gear 41 is separated from the passive gear assembly 50.

[0037] like Figure 1-4 In the embodiment of the present application, the passive gear assembly 50 includes: a dial support shaft 51, a dial gear 52, a dial 53 and a dial retaining ring 54, wherein the dial support shaft 51 is arranged on the mounting surface, the dial gear 52 and the dial 53 are both sleeved on the dial support shaft 51, and the two dial retaining rings 54 are respectively sleeved on both ends of the dial support shaft 51, and respectively correspond to the side walls of the dial gear 52 and the dial 53, and the dial 53 has a round pin and an outward convex arc.

[0038] like Figure 1-4In the embodiment of the present application, the paper picking assembly 60 includes: a paper picking roller 61, a paper picking roller core 62, a paper picking roller sleeve 63 and a groove wheel 64, wherein the paper picking roller 61 is arranged on the mounting surface, the paper picking roller core 62 is sleeved on the paper picking roller 61, the paper picking roller sleeve 63 is sleeved on the paper picking roller core 62, and the groove wheel 64 is sleeved on the paper picking roller 61 and has a radial groove 65 and an inner concave arc 66. When the dial 53 in the passive gear assembly 50 rotates to the third position, the round pin on the dial 53 enters the radial groove 65 and drives it to rotate; when the dial 53 rotates to the fourth position, the round pin disengages from the radial groove 65, and the outer convex arc on the dial 53 presses against the inner concave arc 66 to pause the movement of the groove wheel 64.

[0039] When picking up paper, the electromagnet 25 generates magnetism and attracts the baffle plate 22 to move toward the support plate 21. The driving gear 41 moves to the first position under the elastic support of the pressing spring 32 and meshes with the dial gear 52. The driving gear 41 drives the dial gear 52 and the dial 53 to rotate under the action of the driving motor. When the dial 53 rotates to its third position, the round pin on the dial 53 enters the radial groove 65 and drives the groove wheel 64 to rotate. At this time, the groove wheel 64 drives the paper pickup roller 61 to rotate, and then drives the paper pickup roller core 62 and the paper pickup roller sleeve 63 to rotate. The paper pickup roller sleeve 63 contacts the paper and drives it to move. When the dial 53 rotates to the fourth position, the round pin disengages from the radial groove 65, and the outer convex arc on the dial 53 presses against the inner concave arc 66 to suspend the movement of the groove wheel 64. At this time, the paper pickup roller sleeve 63 no longer drives the paper to move, and the paper stops moving.

[0040] The intermittent paper picking mechanism provided in the present application has a simple structure, low cost, and can ensure the stability and reliability of paper picking.
