Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to a side-flip cover easy-to-change paper printer. Background Technology

[0002] In related technologies, currently available lottery printers (such as thermal ticket printers) typically have their paper tray located behind the printhead, and paper changing is achieved through a flip-up top cover. Users must fully lift the top cover to access the internal paper roll. However, because the top cover's rotation axis is located behind the paper tray, when the top cover is open, it directly obstructs the space above the paper tray, leading to the following drawbacks:

[0003] 1) Limited operating space: Users need to lift the top cover to a near-vertical angle (e.g., greater than 90°) to obtain enough space for paper changing. In a narrow counter environment, it is easy to collide with obstacles. When loading paper by lifting the top cover from above, the top cover is above the paper roll, which can easily block the operating space for paper changing.

[0004] 2) Low paper changing efficiency: When loading paper, the user's view is blocked by the lifted cover, which can easily cause paper misalignment.

[0005] In summary, the technical problems existing in the relevant technologies need to be improved. Summary of the Invention

[0030] Figure 1 This is a schematic diagram of the structure of a side-flip easy-to-change paper printer provided in an embodiment of this application. The printer includes a side-flip mechanism 100 and a main body mechanism 200.

[0031] The side-flipping mechanism 100 is rotatably mounted on one end of the main body 200 via the rotating connector 12. The side-flipping mechanism 100 rotates about the axis of the rotating connector 12 to open or close the functional area of ​​the main body 200.

[0032] In some embodiments, such as Figure 1 and Figure 2 As shown, the side-flipping mechanism 100 includes a flipping plate 23, a paper guide roller 13, and a movable buckle 11;

[0033] One side of the flip cover 23 is rotatably connected to the main body mechanism 200 via a rotating connector 12, and the other side is provided with a movable buckle 11; when the flip cover 23 is in the closed position, the movable buckle 11 forms a fastening connection with the corresponding side of the main body mechanism 200.

[0034] The paper guide roller 13 is fixed to the inside of the flip cover plate 23 by fasteners to restrict the direction of the paper.

[0035] The main structure includes a paper feeding device 24, a main control module 25, a paper tray 27, a paper shortage detection device 26, a paper out detection device 28, a button module 29, and a paper loading bearing 30.

[0036] The paper feeding device 24 has a rotating shaft mounting hole on one side and a fastening interface on the other side. The fastening interface is used to fasten with the movable buckle 11, and the rotating shaft mounting hole is used to cooperate with the rotating connector 12.

[0037] The paper bag 27 is connected to the paper feeding device 24 via a hinge assembly, and the paper bag 27 is used to load paper.

[0038] The main control module 25 is located below the paper feeding device 24 and is physically isolated from the paper feeding device 24 by a metal isolation plate. It is used to handle all control processes, including paper feeding, printing operation, status monitoring, and abnormal handling.

[0039] The paper running out detection device 26, the paper shortage detection device 28, and the key module 29 are arranged around the paper bag 27 to monitor the paper status and receive user input.

[0040] Paper bearings 30 are rotatably mounted on both sides of the paper bag 27 to cooperate with the paper bag 27, support and fix the paper.

[0041] In some embodiments, the movable buckle 11 is an elastic buckle, and the paper feeding device 24 has a wedge-shaped guide groove at the corresponding position to guide the movable buckle 11 into the fastening interface to complete the locking. The fastening direction of the movable buckle 11 is perpendicular to the paper feeding direction to avoid accidental opening of the cover due to vibration and to improve the convenience of paper replacement. Optionally, the paper feeding device 24 is used to feed paper and heat-print information characters on the paper, and may include, but is not limited to, a rubber roller, a stepper motor, a paper guide roller, a branding device, and a paper guiding structure. The paper guide roller is used to control the height of the paper so that the detection results of the photoelectric components (such as the paper shortage detection device 26 and the paper shortage detection device 28) are correct. The paper guiding structure has a concave design, and the high edges on both sides can limit the paper's travel path from deviating. The branding device is used to press anti-counterfeiting marks (such as raised QR codes and microtext) on the paper to improve the anti-counterfeiting level. The paper feeding device 24 has a built-in cutter for cutting the paper so that the printed paper is of uniform length.

[0042] In some embodiments, the rotating connector 12 is a rotating shaft; both ends of the rotating shaft are inserted into the rotating shaft mounting holes of the main body mechanism 200 for fixation; the connecting part of the side flip cover mechanism 100 is sleeved on the middle part of the rotating shaft 12, and the side flip cover mechanism 100 covers the paper feed port of the paper feeding device 24.

[0043] In some embodiments, the paper shortage detection device 28 is a photoelectric sensor, which is located at the bottom of the paper storage compartment of the paper bag 27.

[0044] In some embodiments, the paper sack 27 is located in the rear half of the main body 200 and is used to hold unprinted paper, such as lottery ticket rolls.

[0045] In some embodiments, the button module 29 includes at least one mechanical button or capacitive touch button; the button module 29 is disposed on the side wall or top of the paper bag 27 and is used to trigger the paper printing process and verify the paper printing effect.

[0046] In some embodiments, the main control module 25 controls the operation of the paper printing function, which includes data communication, paper feed control, heating printing, and paper detection. Optionally, the main control module 25's workflow is to acquire and verify data, then precisely control the paper feed device 24, turn the print head on and off according to the printing data content, and control the heating / impact sequence of the print head. The print head is located directly above the paper feed path of the paper feed device 24, forming a printing pressure zone together with the rubber roller in the paper feed device 24. At the same time, the main control module 25 maintains the normal operation of the printing process, confirms the completion of printing data, ticket cutting, and ticket dispensing.

[0047] In some embodiments, the inner sides of the two side walls are provided with axial grooves, and the end of the paper bearing 30 is embedded in the axial grooves; the axial grooves form a circumferential limit on the paper bearing 30, so that the paper bearing 30 maintains stable rotation in the paper bag.

[0048] In some embodiments, the paper depletion detection device 26 is a photoelectric sensor, disposed on one side of the two side walls and located below the axial groove.

[0049] The following is a detailed introduction and explanation of the solution of the present invention, using a specific lottery ticket printing scenario as an example:

[0050] When the aforementioned side-flip easy-paper printer is used for lottery printing, its operation is as follows: After power-on, the main control module 25 initializes each module; the paper status is detected by the paper detection device (including the paper low detection device 26 and the paper out detection device 28, etc.), and the paper is fed and printed by the printing module (including the paper feeding device 24, the paper guide roller 13, and the paper tray 27, etc.). When a paper shortage or paper jam is detected, the fault light of the button module 29 stays on, indicating that normal lottery printing cannot continue. At this time, the user opens the flip cover 23, loads the paper into the paper tray 27, and fixes the paper by the paper loading bearing 30. Then, the user closes the flip cover 23 to realize the paper replacement operation and eliminate the corresponding fault. When the main control module 25 has a communication abnormality, the fault light of the button module 29 enters a slow frequency flashing mode, indicating that lottery printing cannot continue. When the power indicator light of the power module goes out, the printer stops working.

[0051] This application provides a side-flip easy-to-change paper printer, which includes a side-flip mechanism and a main body mechanism. The side-flip mechanism is rotatably mounted on one end of the main body mechanism via a rotating connector. The side-flip mechanism rotates around the axis of the rotating connector to open or close the functional area of ​​the main body mechanism. This application enables the application of a side-flip mechanism on the printer, allowing the flip cover to rotate to the side of the printer when opened, avoiding the problem of overhead space obstruction. This ensures that the user's line of sight to the printer's paper tray is unobstructed when changing paper, improving paper changing efficiency and accuracy, and reducing paper loading error rate.
