[0002] The paper feed tray, also known as the paper tray, paper cassette, or paper feeder, is a key component in a printer used to store and transport paper. It is one of the core components for the efficient operation of a printer, significantly improving printing convenience, stability, and versatility through automated paper feeding and intelligent design. Its value lies not only in saving time and labor costs but also in expanding the printer's functional boundaries by adapting to various paper types.

[0003] The printer paper tray is mainly used to store the paper to be printed, ensuring that the printer can quickly feed the paper into the printer one sheet at a time through mechanical or electronic control when needed, and ensuring that the paper enters the printer in the correct position and orientation to avoid printing misalignment or paper jams.

[0004] Printer paper trays typically have adjustable baffles and paper guides to accommodate different paper sizes, such as A4, A3, letter paper, and photo paper. However, current printers are generally designed for A3, A4, and A5 paper. For letter paper or photo paper, especially photo paper, which comes in various sizes, the baffles on existing printers cannot be precisely adjusted to fit the size of the photo paper. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the baffle of existing printers cannot be precisely adjusted to fit the size of photo paper.

[0006] To solve the above-mentioned technical problems, the present invention provides a printer paper feeding structure, comprising:

[0020] This utility model solves the above-mentioned existing problems and other existing problems not mentioned above, and brings at least the following innovative advantages:

[0021] This utility model relates to a printer paper feeding structure and printer. By setting a movable lead screw in the first paperboard and threading the lead screw to the second paperboard, the second paperboard can be pushed forward or backward by rotating the lead screw clockwise or counterclockwise. This allows for precise adjustment of the position of the second paperboard, thus solving the problem that the current printer's baffle cannot be precisely adjusted to accommodate different photo paper sizes.

[0022] This utility model relates to a printer paper feeding structure and printer. By setting a limiting plate for the third paperboard and connecting the limiting plate and the third paperboard with an elastic metal sheet, the locking teeth under the limiting plate and the second rack are engaged to position the third paperboard. When adjustment is needed, the limiting plate can be moved. At this time, the elastic metal sheet is elastically deformed, causing the locking teeth and the second rack to disengage, thus enabling the adjustment of the third paperboard.

[0028] In the accompanying drawings, the same reference numerals represent the same parts. It should be noted that the described embodiments are only some, not all, of the embodiments disclosed herein.

[0029] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure. Example 1

[0030] like Figures 1 to 3 As shown, the paper feeding structure of this utility model printer includes: a paper feed tray 1, Figure 1 and Figure 2 The paper tray 1 is shown to have a paper slot 2; the paper slot 2 has a first sliding groove 3; and a first baffle plate 4. Figure 2 The first guide plate 4 is shown to have a fixedly connected first slide bar 5, and the first guide plate 4 is installed inside the paper feeding slot 2. Figure 1 This demonstrates the slidable connection between the first slider 5 and the first groove 3; as shown. Figure 2 As shown, the first baffle plate 4 has a second groove 6 and a first connecting hole 7; the lead screw 8, Figure 1 The lead screw 8 is shown to be movably connected to the first connecting hole 7, and the lead screw 8 is arranged parallel to the first slide bar 5; one end of the lead screw 8 is at least partially outside the first stop plate 4; Figure 2 The lead screw 8 is shown to have two limiting members 12 that are either fixedly or detachably connected. These two limiting members 12 abut against both sides of the first baffle plate 4, meaning the lead screw 8 is movably connected to the first baffle plate 4 via the two limiting members 12; knob 9, Figure 1 and Figure 2 The knob 9 and the lead screw 8 are shown to be fixedly connected at the end outside the first stop plate 4; the second stop plate 10 is shown. Figure 2 The second guide plate 10 is shown to have a fixedly connected second slide bar 11, which is slidably connected to the second slide groove 6; the second guide plate 10 is threadedly connected to the lead screw 8; more specifically, as Figure 2 As shown, it also includes a nut, wherein the second baffle plate 10 has a second connecting hole 13, and a fixedly connected nut 14 is provided in the second connecting hole 13, and the nut 14 is threadedly connected to the lead screw 8.

[0031] in Figure 3 The following diagrams illustrate the application effects of this utility model. Figure 1 As shown, the paper feeding structure of this utility model printer has a movable screw 8 connected to the first paper stop 4 and threadedly connected to the second paper stop 10. This allows the second paper stop 10 to be pushed forward or backward by rotating the screw 8 clockwise or counterclockwise, thus achieving precise adjustment of the position of the second paper stop 10. This solves the problem that the current printer baffles cannot be precisely adjusted to suit different photo paper sizes.

[0032] like Figure 2As shown, the paper feeding slot 2 has a third sliding groove 15 on each side, and a synchronous gear 16 movably connected to the paper feeding box 1 is located at the middle position of the two third sliding grooves 15; it includes two third baffles 17, each of which has a third sliding strip 18 and a first rack 19 fixedly connected. Figure 1 The two third guide plate 17 are shown to be slidably mounted on both sides of the paper feeding slot 2 via the third slide bar 18 and the third slide groove 15; the first racks 19 of the two third guide plate 17 are respectively meshed with the synchronous gear 16. Figure 2 The paper feed trough 2 is shown to have a second toothed rack 20 fixedly connected to at least one side; Figure 1 and Figure 2 Each of the third baffle plates 17 is shown to be equipped with a limiting plate 21; the limiting plate 21 is located vertically above the second rack 20; the lower part of the limiting plate 21 has a fixed connecting tooth 22, which engages with the second rack 20. Figure 2 As shown, it also includes an elastic metal sheet 23, one end of which is fixedly connected to the third baffle plate, and the other end of which is fixedly connected to the limiting plate 21.

[0033] The paper feeding structure of this utility model printer sets a limiting plate 21 on the third paperboard 17 and connects the limiting plate 21 and the third paperboard 17 with an elastic metal sheet 23. The engagement between the locking teeth 22 below the limiting plate 21 and the second rack 20 achieves the positioning of the third paperboard 17. When adjustment is required, the limiting plate 21 can be moved. At this time, the elastic metal sheet 23 elastically deforms, causing the locking teeth 22 and the second rack 20 to disengage, thereby realizing the adjustment of the third paperboard 17. Example 2
