AI Technical Summary
The paper feed mechanism of traditional printers is prone to misalignment when printing small-sized paper, which affects the printing quality.
Printers with anti-offset structures use a combination of a two-way threaded rod and a limiting plate. The position of the limiting plate is adjusted by a knob to fix the paper and prevent it from shifting.
This effectively prevents the paper from shifting on the cardboard, ensuring print quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer technology, and in particular to a printer with an anti-offset structure. Background Technology
[0002] A printer is an output device that converts digital information into physical form, such as visible content on media like paper, film, or cloth. It is an important peripheral for electronic devices such as computers, mobile phones, and tablets, and is widely used in many fields such as office, education, design, industrial manufacturing, and home entertainment.
[0003] During the printing process, paper must first be placed on the paper feed mechanism and then fed into the printer for printing. However, traditional printers often have a fixed paper feed mechanism. When printing smaller paper sizes, the paper may shift when placed on the paper feed mechanism, thus affecting the printing quality. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a printer with an anti-offset structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A printer with an anti-offset structure includes a printer body and a paper feeder. The paper feeder is installed at the paper inlet of the printer body. Both ends of the paper feeder have strip-shaped through grooves. Both ends of the back side of the paper feeder are fixedly installed with extension plates. A bidirectional threaded rod is rotatably arranged between the two extension plates. A knob is fixedly installed on one side of the bidirectional threaded rod. Both ends of the bidirectional threaded rod are slidably fitted with nut pairs. A connector is fixedly installed at one end of the nut pairs. The connector is movably located in the strip-shaped through groove. A limit plate is fixedly installed at one end of the connector.
[0007] Furthermore, in a preferred configuration, bearings are embedded and installed on the inner sides of both extension plates.
[0008] Furthermore, in a preferred configuration, the two ends of the bidirectional threaded rod are respectively connected to two bearings.
[0009] In addition, a preferred structure is that two grooves are provided at both ends of the inner side of the paperboard, and the two grooves are located at both ends of the strip-shaped through groove.
[0010] In addition, a preferred structure is that a silicone pad is installed on the inner side of the limiting plate, and sliders are provided at both ends of the bottom of the limiting plate. The two sliders are located at both ends of the connector, and the sliders slide within the groove.
[0011] Furthermore, a preferred configuration is that the bidirectional threaded rod is fitted with a threaded rod protective shell.
[0012] The beneficial effects of this utility model are as follows:
[0013] In this invention, rotating the knob drives the bidirectional threaded rod to rotate, causing the two limiting plates to move towards or away from each other. The position of the two limiting plates is adjusted according to the size of the paper. The two limiting plates limit the printing paper, preventing the paper from shifting on the paperboard, which is beneficial for the printer to print the paper. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-7A printer with an anti-offset structure includes a printer body 1 and a paper tray 2. The paper tray 2 is installed at the paper feed position of the printer body 1. Both ends of the paper tray 2 are provided with strip-shaped through grooves 21. Both ends of the back side of the paper tray 2 are fixedly installed with extension plates 22. A bidirectional threaded rod 5 is rotatably arranged between the two extension plates 22. A knob 4 is fixedly installed on one side of the bidirectional threaded rod 5. Both ends of the bidirectional threaded rod 5 are slidably fitted with nut pairs 8. A connector 6 is fixedly installed at one end of the nut pairs 8. The connector 6 is movably located in the strip-shaped through groove 21. A limit plate 3 is fixedly installed at one end of the connector 6.
[0024] Bearings 9 are embedded in the inner sides of both outer plates 22.
[0025] Meanwhile, the two ends of the bidirectional threaded rod 5 are connected to two bearings 9 respectively. When the bidirectional threaded rod 5 rotates, the outer extension plate 22 will not rotate under the action of the bearings 9.
[0026] Furthermore, two grooves 23 are provided at both ends of the inner side of the cardboard 2, and the two grooves 23 are located at both ends of the strip groove 21.
[0027] Meanwhile, a silicone pad 32 is installed on the inner side of the limiting plate 3. The silicone pad 32 prevents hard materials, such as the edge of the cardboard, from being worn. Slider 31 is provided at both ends of the bottom of the limiting plate 3. The two sliders 31 are located at both ends of the connector 6 respectively. The sliders 31 slide in the groove 23. The sliders 31 provide guidance for the movement of the limiting plate 3, and at the same time make the movement of the limiting plate 3 more stable.
[0028] Furthermore, a threaded rod protective shell 7 is installed on the outside of the bidirectional threaded rod 5, which protects the bidirectional threaded rod 5.
[0029] In this embodiment, rotating the knob 4 causes the bidirectional threaded rod 5 to rotate, causing the two nut pairs 8 to move towards or away from each other on the bidirectional threaded rod 5, which in turn causes the two limiting plates 3 to move towards or away from each other. The positions of the two limiting plates 3 are adjusted according to the size of the paper to be printed. When the two limiting plates 3 are adjusted to the required positions, the paper to be printed is placed on the paper tray 2. The paper will not shift under the restriction of the two limiting plates 3, which is beneficial for the printer to print the paper.
[0030] In this utility model, rotating the knob 4 drives the bidirectional threaded rod 5 to rotate, causing the two limiting plates 3 to move towards or away from each other. The position of the two limiting plates 3 is adjusted according to the size of the paper. The two limiting plates 3 limit the printing paper and prevent the paper from shifting on the paperboard 2, which is beneficial for the printer to print the paper.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
