[0002] The printer should output paper smoothly throughout the process. In the process of outputting paper, the tail end of the paper is easy to curl up and contact the print head, so that ink sticks to the paper. Although the existing paper output structure can flatten the tail end of the paper, it has a complex structure, has a large paper output resistance, and requires a large space. Utility Model Content

[0003] The embodiment of the present application provides a printer paper output auxiliary structure and a printer to solve the problems existing in the related technology. The technical solution is as follows:

[0004] In a first aspect, an embodiment of the present application provides a printer paper output auxiliary structure, including:

[0005] The paper feed shaft is installed inside the printer and transports the printing paper in the printer to the paper output end of the printer;

[0006] The paper output shaft is installed on the paper output end of the printer, and the paper feed shaft transports the printing paper to the paper output shaft;

[0007] Paper output star wheel, which is installed on the printer, cooperates with the paper output shaft to output paper;

[0008] The paper output driven wheel is installed on the paper output end of the printer. The printing paper is transported to the paper output driven wheel through the paper output shaft, and the printing paper is output through the paper output driven wheel to make the printing paper flat and reduce the paper output resistance.

[0009] In one embodiment,

[0010] When the paper feed shaft delivers one end of the printing paper to the paper output end, the paper output star wheel presses the end of the printing paper away from the paper feed shaft.

[0011] In one embodiment,

[0012] The paper ejection driven wheel is located above the side of the paper ejection shaft away from the printer, and the height of the paper ejection driven wheel is higher than the height of the paper ejection shaft.

[0013] In one embodiment,

[0014] When the printing paper is output from the printer, the paper output driven roller fits against the printing paper to keep the printing paper flat and reduce the paper output resistance.

[0015] In one embodiment, it further includes:

[0016] The driving assembly is installed on the printer and is connected to the paper output shaft to move the paper output shaft.

[0017] In one embodiment,

[0018] The paper output driven wheel is located on the outer side of the paper output shaft, and the paper output star wheel is located on the inner side of the upper part of the paper output shaft.

[0019] In a second aspect, an embodiment of the present application provides a printer, including:

[0028] By setting the paper output star wheel, paper output shaft and paper output driven wheel, the printing paper is leveled during the paper output process. When the printing paper is separated from the paper feed shaft, the driven wheel replaces the paper feed shaft to level the paper tail, so as to prevent the tail end of the printing paper from curling up and contacting the print head assembly, reduce the paper output resistance, and improve the printing quality of the printer. At the same time, by setting the paper output structure on the original printer to the paper star wheel, paper output shaft and paper output driven wheel structure, the occupied space is greatly reduced.

[0035] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0036] Figure 1-Figure 2 A structural diagram of a printer paper output auxiliary structure according to an embodiment of the present application is shown.

[0037] like Figure 1-Figure 2 As shown, the auxiliary structure may include:

[0038] A paper feed shaft 3 is installed inside the printer, and the paper feed shaft 3 transports the printing paper 1 in the printer to the paper output end of the printer;

[0039] The paper output shaft 7 is installed on the paper output end of the printer, and the paper feed shaft 3 delivers the printing paper 1 to the paper output shaft 7;

[0040] A paper discharge star wheel 5 is installed on the printer, and cooperates with a paper discharge shaft 7 to discharge paper;

[0041] The paper ejection driven wheel 6 is installed on the paper ejection end of the printer. The printing paper 1 is transported to the paper ejection driven wheel 6 via the paper ejection shaft 7. The printing paper 1 is output via the paper ejection driven wheel 6 to flatten the printing paper 1 and reduce the paper ejection resistance.

[0042] In this embodiment, the paper discharge shaft 7, the paper discharge star wheel 5 and the paper discharge driven wheel 6 are all provided in a group, which saves the space of the printer. The paper feed shaft 3 conveys the printing paper 1 to the paper discharge shaft 7. The distance between the paper feed shaft 3 and the paper discharge shaft 7 is less than the length of the printing paper 1. The paper feed shaft 3 and the paper discharge shaft 7 convey the printing paper 1 in the same direction. The printing paper 1 is conveyed to the paper discharge shaft 7 through the paper feed shaft 3. The printing paper 1 conveys the leading end of the printing paper 1 to the paper discharge shaft 7 through the paper feed shaft 3. When the leading end of the printing paper 1 contacts the paper discharge shaft 7, the trailing end of the printing paper 1 is located at the paper feed shaft 3. When the leading end of the printing paper 1 passes through the paper discharge shaft 7, the paper discharge shaft 7 rotates to make the printing paper 1 continue to move.

[0043] When the leading end of the printing paper 1 contacts the paper output shaft 7, the paper output star wheel 5 contacts the printing paper 1, and the paper output star wheel 5 presses the leading end of the printing paper 1 to prevent the leading end from tilting and causing paper jams, and assists the printing paper 1 to continue moving;

[0044] When the front end of the printing paper 1 is transported to the paper ejection driven wheel 6, under the action of friction, the paper ejection driven wheel 6 rotates in contact with the surface of the printing paper 1, reducing the paper ejection resistance and making the paper ejection smoother;

[0045] When the tail end of the printing paper 1 is completely separated from the paper feeding shaft 3, the paper feeding shaft 3 cannot play the role of flattening the tail end of the printing paper 1. At this time, the printing paper 1 is flattened by the paper discharge star wheel 5 and the paper discharge driven wheel 6;

[0046] By setting the paper discharge star wheel 5, the paper discharge shaft 7 and the paper discharge driven wheel 6, the printing paper 1 is leveled during the paper discharge process. When the printing paper 1 is separated from the paper feed shaft 3, the driven wheel 6 levels the tail end of the printing paper 1 to prevent the tail end of the printing paper 1 from being lifted up and contacting the print head assembly 4, thereby reducing the paper discharge resistance and improving the printing quality of the printer. At the same time, by setting the paper discharge structure on the original printer to the paper discharge star wheel 5, the paper discharge shaft 7 and the paper discharge driven wheel 6 structure, the occupied space is greatly reduced.

[0047] The paper discharge shaft 7 is matched with a set of paper discharge star wheels 5 and a set of driven wheels 6, which saves the internal space of the printer and reduces the paper discharge resistance. At the same time, the paper discharge driven wheel 6 is smaller in size and saves more space than the traditional paper discharge structure.

[0048] like Figure 1-Figure 2 As shown, in one embodiment,

[0049] When the paper feed shaft 3 conveys one end of the printing paper 1 to the paper discharge end, the paper discharge star wheel 5 presses the end of the printing paper 1 away from the paper feed shaft 3 .

[0050] In this embodiment, when the leading end of the printing paper 1 reaches the paper discharge star wheel 5, the paper discharge star wheel 5 presses the paper head to prevent the paper head from tilting up and causing paper jam and assists the printing paper 1 to continue moving.

[0051] like Figure 1-Figure 2As shown, in one embodiment,

[0052] The paper discharge driven wheel 6 is located above the side of the paper discharge shaft 7 away from the printer, and the height of the paper discharge driven wheel 6 is higher than the height of the paper discharge shaft 7 .

[0053] In this embodiment, since the height of the paper output driven wheel 6 is higher than the paper output shaft 7, the printing paper 1 will generate an upward force during the paper output process. When the tail end of the printing paper 1 is completely separated from the paper feed shaft 3, this force will prevent the tail of the paper from curling up and hitting the print head.

[0054] like Figure 1-Figure 2 As shown, in one embodiment,

[0055] When the printing paper 1 is output from the printer, the paper output driven wheel 6 is in contact with the printing paper 1 to keep the printing paper 1 flat and reduce the paper output resistance.

[0056] In this embodiment, when the front end of the printing paper 1 is transported to the paper ejection driven wheel 6, under the action of friction, the paper ejection driven wheel 6 rotates in contact with the surface of the printing paper 1, thereby reducing the paper ejection resistance and making the paper ejection smoother.

[0057] When the rear end of the printing paper 1 is completely separated from the paper feed shaft 3, the paper feed shaft 3 cannot play a role in flattening the rear end of the printing paper 1. At this time, the printing paper 1 is flattened by the paper discharge star wheel 5 and the paper discharge driven wheel 6.

[0058] like Figure 1-Figure 2 As shown, in one embodiment, it also includes:

[0059] The driving assembly is installed on the printer, and the driving assembly is connected to the paper output shaft 7 to make the paper output shaft 7 move.

[0060] In this embodiment, the paper output shaft 7 and the paper feed shaft 3 are both driven by a driving component, which may be a driving motor, a gear set or other components that can drive the paper output shaft 7 to rotate. In this solution, the paper output shaft 7 is driven to rotate by a driving motor.

[0061] In one embodiment,

[0062] The paper discharge driven wheel 6 is located on the outer side of the paper discharge shaft 7 , and the paper discharge star wheel 5 is located on the outer side of the upper part of the paper discharge shaft 7 .

[0063] In this embodiment, when the printing paper 1 is output, the paper output star wheel 5 and the paper output driven wheel 6 are respectively located on both sides of the printing paper 1. The paper output star wheel 5 assists one side of the printing paper 1. The paper output star wheel 5 presses one side of the front end of the printing paper 1 to prevent the front end from tilting and causing paper jams, and assists the printing paper 1 to continue moving;

[0064] The paper output driven wheel 6 assists one side of the printing paper 1. When the tail end of the printing paper 1 is completely separated from the paper feed shaft 3, the paper feed shaft 3 cannot flatten the tail end of the printing paper 1. At this time, the paper output driven wheel 6 flattens the tail end of one side of the printing paper 1.

[0065] Figure 1-Figure 2 FIG. 2 shows a structural diagram of a printer according to an embodiment of the present utility model. Figure 1-Figure 2 As shown, the printer may include:

[0066] A printer paper output auxiliary structure as described in any one of the above embodiments; and

[0067] A paper separation block 2 is installed inside the printer and is located on one side of the paper feeding shaft 3;

[0068] The print head assembly 4 is installed inside the printer, and the print head assembly 4 is located between the paper output shaft 7 and the paper feed shaft 3.

[0069] In this embodiment, in the initial state, the printing paper 1 is located in the printer, and the printing paper 1 is located above the paper separation block 2. After the printer is started, the paper separation block 2 separates the printing paper 1 and transports it separately to the paper feed shaft 3. The paper feed shaft 3 transports the printing paper 1 to the paper output shaft 7. During the transportation process, the print head assembly 4 prints the printing paper 1, and transports it to the paper output shaft 7 after printing.

[0070] like Figure 1 As shown, in one embodiment,

[0071] The printer has a cavity for storing the printing paper 1, the cavity is connected to the inside of the printing paper 1, and the print head assembly 4 is located in the cavity.

[0072] In this embodiment, the printing paper 1 is stored in the cavity of the printer. When it is needed, the paper separation block 2 transports the printing paper 1 to the paper feeding shaft 3 separately. The printing paper 1 can be placed in the cavity regularly.
