Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer technology, and in particular to a paper feeding device for a self-service printer. Background Technology
[0002] A printer is a computer output device used to print computer-processed results onto various media, the most common being paper, especially A4 paper. Mainstream self-service printers include a printing system and a paper transport system. The paper transport system is responsible for moving paper from the input tray to the printing position and then to the output tray. Specifically, the input device includes a paper tray (for holding the paper to be printed), paper feed rollers (made of rubber, which use friction to feed the paper one sheet at a time, preventing multiple sheets from being fed), and a separator (which works with the paper feed rollers to separate the paper). The guide rollers and positioning mechanism guide the paper to move smoothly, using sensors to detect the paper position and ensure the print head is aligned with the paper. The output device includes the output rollers and output tray, which deliver the printed paper.
[0003] In existing technology, paper feed trays can generally only store about 200 sheets of paper. If there are too many sheets of paper and they are stacked too thickly, it can easily lead to multiple sheets being rolled up or paper jams during paper feeding. Utility Model Content
[0004] The purpose of this invention is to provide a paper feeding device for a self-service printer that increases paper storage capacity and reduces the probability of multiple pages being wound up or paper jams, and has high compatibility with existing self-service printers.
[0005] To achieve the above objectives, this utility model provides a paper feeding device for a self-service printer, including a printer body and a paper feeding tray disposed below the printer body. The paper feeding tray includes a support base and a paper storage slot disposed within the support base. One side of the support base is open, and the paper storage slot is slidably connected to the support base along the opening. The height of the paper storage slot on the side with the opening is greater than the height of the paper storage slot on the side opposite to the opening. A first baffle is disposed at the top position of the paper storage slot on the side with the opening, and a second baffle is disposed at the top position of the paper storage slot on the side opposite to the opening. The width of the first baffle is greater than the width of the second baffle. A spring support member is placed inside the paper storage slot.
[0006] Preferably, a limiting plate is provided on one side of the support base opposite to the opening, and the horizontal plane of the limiting plate is lower than the highest horizontal plane of the paper storage trough.
[0007] Preferably, the paper storage trough is provided with an observation port on the side wall of the opening.
[0008] Preferably, the spring support includes a support plate and a plurality of compression springs fixedly disposed on the bottom surface of the support plate. The support plate is in contact with the inner peripheral wall of the paper storage tank, and the bottom end of the compression spring is in contact with the inner bottom wall of the paper storage tank.
[0009] Preferably, the top surface of the support base is in contact with the bottom surface of the printer body.
[0010] Preferably, both the first baffle and the second baffle are made of elastic materials.
[0011] Preferably, the height of the support base is 0.6-0.8 times the width of the paper storage trough.
[0012] Preferably, the paper storage slot has slots on both sides, and the slots are in contact with the bottom inner wall of the printer body.
[0013] Therefore, the present invention adopts the above-mentioned paper feeding device for a self-service printer, and the beneficial effects are as follows:
[0014] This invention uses a large-sized paper storage slot to hold A4 paper, increasing the paper storage capacity. During the process of transferring the A4 paper to the printer body, the spring support automatically pushes the A4 paper upward to ensure stable transmission. In addition, the first and second baffles made of elastic material guide the A4 paper to move along a preset trajectory, reducing the probability of multiple pages of A4 paper getting wound or paper jams. It has high compatibility with existing self-service printers.
[0015] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0024] like Figure 1-4 As shown, a paper feeding device for a self-service printer is applicable to A4 paper printing scenarios and can be used with self-service printers of models such as Canon GX5580, GX5080, GX6080, GX7080, GX3080, G5080, G6080, and G7080. The specific structure is as follows:
[0025] The printer includes a rectangular printer body 1 (39cm long × 38cm wide × 40cm high), with a paper tray 2 located below it. The paper tray 2 includes a support base 3 and a paper storage slot 4. The support base 3 is made of wood and has overall dimensions of 39cm long × 38cm wide × 15.8cm high. A rectangular opening 5 is located on its left side, through which the paper storage slot 4 is connected to the support base 3 in a pull-out sliding manner. A limiting plate 6 (10cm long × 8cm wide) is located on the right outer wall of the support base 3. The upper surface of the limiting plate 6 is higher than the top right side of the paper storage slot 4 and lower than the top left side of the paper storage slot 4, cooperating with the bottom of the printer body 1 to form a paper transport reference surface.
[0026] The paper storage tray 4 is made of wood, measuring 39cm in length and 22.6cm in width (the height is 0.69 times the width, conforming to the preferred proportions). The left side is 20cm high, and the right side is 15cm high. A first baffle 7 is located at the top of the left side, and a second baffle 8 is located at the top of the right side. The width of the first baffle 7 is greater than the width of the second baffle 8, and both are made of silicone elastic material. A rectangular observation opening 9 (10cm long x 5cm high) is located in the middle of the left side wall for easy viewing of remaining paper. A long, narrow slot 10 (6mm deep) is located at the top of each of the front and rear side walls, fitting into the inner bottom wall of the printer body 1.
[0027] The spring support includes a support plate 11 (29.7cm long × 21cm wide) made of wood. A compression spring 12 (2cm in diameter × 5cm in height) is fixed to each of the four corners of the bottom surface of the support plate 11. The bottom end of the compression spring 12 abuts against the inner bottom wall of the paper storage slot 4. The support plate 11 can slide up and down along the inner wall of the paper storage slot 4 and can hold 1500-2000 sheets of A4 paper.
[0028] In actual use, when loading paper, the paper storage tray 4 is pulled out from the left opening 5 of the support base 3. 1500 sheets of A4 paper are neatly stacked on the support plate 11. The spring is compressed to a height of 3cm. After being pushed into the paper storage tray 4, the edge of the paper contacts and is limited by the first baffle 7 and the second baffle 8. As the printing process proceeds, the number of sheets of paper decreases. The spring force pushes the support plate 11 to gradually rise, always keeping the top layer of paper in effective contact with the paper feed roller of the printer body 1. When the remaining amount of paper is low, paper can be replenished in time through the observation port 9.
[0029] Therefore, the present invention adopts the above-mentioned paper feeding device for a self-service printer, which increases the paper storage capacity and reduces the probability of multiple pages of paper being wound in and paper jams, and has high compatibility with existing self-service printers.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
