[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] See also Figures 1 to 4 , shown is a printer in an embodiment of the present invention, including a printer body 10, a paper box 410, a paper storage assembly 50, a driving assembly 60, a rotating shaft 300, an adsorption assembly 90 and a paper guide assembly 100.

[0039] The printer body 10 includes a paper storage cavity 30 and a paper cavity 40, wherein the paper storage cavity 30 is separated from the paper cavity 40 by a partition 20, wherein the paper storage cavity 30 is located above the paper cavity 40, wherein the paper box 410 is fixedly disposed in the paper cavity 40 and is located below one end of the partition 20, wherein the paper storage assembly 50 is slidably disposed in the paper storage cavity 30 and is located on the upper surface of the partition 20, wherein the driving assembly 60 is fixedly disposed on the partition 20, wherein the rotating shaft 300 is rotatably disposed on the inner wall of the paper storage cavity 30 and is higher than the top of the paper storage assembly 50, wherein the adsorption assembly 90 is fixedly disposed on the rotating shaft 300 and includes a mounting plate 91, a connecting plate 92, a dual-axis motor 93 and an adsorption wheel 94, wherein the mounting plate 91 is fixedly disposed on the outer circumference of the rotating shaft 300 On the circumferential surface, the mounting plate 91 is provided with a through mounting groove 95, the connecting plate 92 is fixedly mounted on the inner wall of the mounting groove 95, the dual-axis motor 93 is fixedly mounted on the side wall of the connecting plate 92, and the output end of the dual-axis motor 93 passes through the two side walls of the mounting plate 91 and is connected to the adsorption wheel 94, the paper guide assembly 100 is fixedly mounted on the outer circumferential surface of the rotating shaft 300, and is arranged at a preset angle to the adsorption assembly 90, wherein the driving assembly 60 drives the paper storage assembly 50 to move on the upper surface of the partition 20 so that the paper on the paper storage assembly 50 contacts the adsorption wheel 94, and the dual-axis motor 93 drives the adsorption wheel 94 to rotate so that the adsorption wheel 94 drives the paper to fall into the paper box 410 through the paper guide assembly 100.

[0040] It can be understood that the stacked paper is placed on the paper storage assembly 50. In the present embodiment, the paper storage assembly 50 is tilted, so the stacked paper is tilted on the paper storage assembly 50. At this time, the paper storage assembly 50 is driven by the driving mechanism 60 so that the outermost sheet of the stacked paper on the paper storage assembly 50 contacts the adsorption wheel 94 of the adsorption assembly 90. In a specific implementation, when the printer is in use, the first sheet of paper used is the paper on the paper box 410 in the paper chamber 40. When the paper in the paper box 410 is used up, it is only necessary to start the dual-axis motor 93, and the dual-axis motor 93 drives the paper box 410 to move the paper box 410 to the paper chamber 40. The suction wheel 94 drives the outermost layer of paper of the paper output assembly 50, and then the outermost layer of paper falls into the paper cavity 40 through the paper guide assembly 100, and falls into the paper box 410 in the paper cavity 40 to complete the paper filling. After the outermost layer of paper is gradually reduced, the driving mechanism 60 drives the paper storage assembly 50 to move, so that the paper stored on the paper storage assembly 50 is always in contact with the suction wheel 94, and then the suction wheel 94 can always drive the paper into the paper box 410, so that the printer does not need to change paper frequently, thereby effectively improving the working efficiency of the printer.

[0041] It is worth mentioning that when replenishing paper in the paper storage assembly 50, you only need to open one side of the printer body 11, then rotate the shaft 300, rotate the adsorption assembly 90 and the paper guide assembly 100 to the outside of the paper storage cavity 30, and then feed the stacked paper into the paper storage assembly 50. In this way, the printer can quickly replace paper and can store enough paper at one time, so as to achieve the purpose of not having to change paper frequently.

[0042] See also Figure 3 In this embodiment, the paper storage assembly 50 includes a paper storage box 51 and a slider 52. The slider 52 is fixed to the bottom of the paper storage box 51. The partition 20 is provided with a guide groove 21 adapted to the slider 52. The paper storage box 51 is in a 7-shaped structure, and an opening is arranged on one side close to the adsorption assembly 90.

[0043] It should be explained that the slider 52 can slide in the guide groove 21 , and thus the slider 52 is driven to move in the guide groove 21 by the driving assembly 60 , so that the paper storage box 51 moves slowly on the upper surface of the partition 20 .

[0044] See also Figure 3 In this embodiment, the side wall of the partition 20 close to the adsorption assembly 50 is connected to an extension plate 200, and a support shaft 210 is rotatably provided on the extension plate 200, and an auxiliary roller 220 is rotatably provided on the support shaft 210. For the specific structure, please refer to Figure 6 .

[0045] It should be explained that when the paper guide assembly 100 guides the paper brought out by the suction wheel 94 , the paper guide assembly 100 cooperates with the rotating auxiliary roller 220 to allow the paper to fall smoothly into the paper box 410 .

[0046] For further information, see Figure 3 A guide plate 400 is fixedly connected to the inner wall of the paper cavity 40 at an angle. The guide plate 400 is located below the end of the partition 20 and above the paper box 410 .

[0047] It is understandable that before the paper falls into the paper box 410 , it is guided by the guide plate 400 so that the paper can fall into the paper box 410 more smoothly, thereby completing the filling of the paper smoothly.

[0048] See also Figure 5In this embodiment, the driving assembly 60 drives the paper storage assembly 50 to slide on the upper surface of the partition 20 through the first transmission assembly 70 and the second transmission assembly 80. The driving assembly 60 includes a driving motor 61 and an output shaft 62. The output end of the driving motor 61 is connected to the first transmission assembly 70 through the output shaft 62. The driving motor 61 drives the first transmission assembly 70, so that the first transmission assembly 70 drives the paper storage box 51 to slide on the partition 20 through the second transmission assembly 80. The first transmission assembly 70 includes a first bevel gear 71, a second bevel gear 72 and a transmission shaft 73. The first bevel gear 71 is fixed to the first transmission assembly 70. Connected to the output shaft 62, the second bevel gear 72 is meshed with the first bevel gear 71, one end of the transmission shaft 73 is fixedly connected to the bottom of the second bevel gear 72, and the other end is rotatably arranged in the partition 20, the second transmission assembly 80 includes a third bevel gear 81, a fourth bevel gear 82 and a transmission screw 83, the third bevel gear 81 is fixedly arranged on the transmission shaft 82, the fourth bevel gear 82 is meshed with the third bevel gear 81, one end of the transmission screw 83 is fixedly connected to the fourth bevel gear 82, and the other end is arranged on the inner wall of the partition 20, a support plate 22 is arranged in the partition 20, and the transmission screw 83 passes through the support plate 22.

[0049] It needs to be explained that the transmission screw 83 is specifically arranged in the guide groove 21, and the support plate 22 is used to support the transmission screw 83. During the specific implementation, the drive motor 61 is started, and the drive motor 61 drives the first bevel gear 71 through the output shaft 62. The first bevel gear 71 drives the transmission shaft 73 to rotate through the second bevel gear 72 meshing therewith. The rotating transmission shaft 73 drives the third bevel gear 81 to rotate, and the third bevel gear 81 drives the fourth bevel gear 82 meshing therewith to rotate, and the fourth bevel gear 82 drives the transmission screw 83 to rotate. The transmission screw 83 penetrates the slider 52, and the slider 52 is provided with an internal threaded hole compatible with the transmission screw 83. Therefore, when the transmission screw 83 rotates, the slider 52 will slide in the guide groove 21, and the slider 52 will drive the paper storage box 51 to slide on the upper surface of the partition 20.

[0050] See also Figure 4 In this embodiment, the paper guide assembly 100 includes a connecting rod 110, a rotating shaft 120 and a guide wheel 130 symmetrically fixed to the outer surface of the rotating shaft 300, the end of the rotating shaft 120 passes through the connecting rod 110, the guide wheel 130 is fixed to the rotating shaft 120, and a bearing 140 is provided at the place where the rotating shaft 120 passes through the connecting rod 110.

[0051] It should be explained that after the adsorption wheel 94 on the adsorption assembly 90 adsorbs the paper, the paper will slowly come into contact with the guide wheel 130, and then the guide wheel 130 will slowly rotate under the action of the paper and guide the paper so that the paper falls into the paper cavity 40 along the specified direction.

[0052] See also Figure 1 In this embodiment, a cover plate 11 is hingedly connected to the top of the printer body 10, and a first paper outlet 12, a second paper outlet 13 and an operation panel 14 are provided on the side wall of the printer body 10. The operation panel 14 is provided above the first paper outlet 12 and the second paper outlet 13. Figure 7 A door 15 is hingedly connected to the side wall of the printer body 10 . A handle 17 and a heat dissipation port 16 are provided on the side wall of the door 15 . The handle 17 is provided above the heat dissipation port 16 .

[0053] It can be understood that the compartment door 15 is opened, and then the shaft 300 is rotated to rotate the adsorption component 90 and the paper guide component 100 out of the paper storage cavity 30, and then the paper can be placed in the paper storage component 50 to complete the paper filling, and the compartment door can be conveniently opened through the handle 17, and the printer can be cooled through the heat dissipation port 16.

[0054] In summary, the printer in the above-mentioned embodiment of the present invention places the stacked paper in the paper storage assembly 50, and at this time, the paper storage assembly 50 is driven to move by the driving mechanism 60 so that the paper stored on the paper storage assembly 50 contacts the adsorption wheel 94. When the printer uses paper, it will first use the paper in the paper box 410. When the paper in the paper box 410 is used up, the dual-axis motor 93 drives the adsorption wheel 94 to rotate, and the adsorption wheel 94 guides the paper in the paper storage assembly 50 and drops it into the paper box 410 of the paper cavity 40 through the paper guide assembly 100, thereby completing the paper replenishment, and then the printer does not need to frequently replace the paper in the paper box, thereby improving the working efficiency of the printer, and by placing the paper in the paper storage assembly 50, convenient paper replacement can be completed.
