Description

Printer paper feed bracket

Technical Field

The utility model relates to the technical field of printer paper feeding, in particular to a printer paper feeding bracket.

Background technique

A printer is a piece of computer hardware that outputs documents or geometric figures in a digital format of some common specification.

An inkjet printer is a printer that sprays ink onto paper. An inkjet printer usually consists of an inkjet print head, a mechanical system, an ink supply device, a paper feed device, and a circuit system. When in use, the user will place the paper on the paper feed tray in the paper feed device. When printing starts, the mechanical system will first transport the paper on the paper feed tray to the bottom of the inkjet print head. The inkjet print head will spray different colors of ink onto the paper according to the requirements of the image or text through the control of the circuit system to form an image or text.

The paper feed bracket on the existing printer only has two raised blocks on the bracket for positioning and guiding the paper. The position of the raised blocks is fixed. For paper with the same width and the distance between the two raised blocks, the deviation of the paper from the guide will be reduced during printing. For paper with different widths and the distance between the two raised blocks, the deviation of the paper from the guide will be increased during printing, which will cause the paper to tilt when entering the printer, thus causing the printer to jam and further reduce the speed of paper printing. To this end, we propose a printer paper feed bracket.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-7, the utility model provides a technical solution:

Embodiment 1,

A printer paper feed bracket, comprising:

A printer body 1, a paper feed bracket 2 is slidably connected to the surface of the printer body 1, and is used to carry paper entering the printer;

The adjusting component 3 is arranged on the surface of the paper feed bracket 2. The adjusting component 3 guides the paper of different sizes on the paper feed bracket 2 so that the paper does not tilt when entering the printer, thereby preventing the tilted paper from entering the printer and causing a paper jam in the printer;

The auxiliary component 4 is arranged on the side of the adjusting component 3, and the auxiliary component 4 can assist the paper on the paper feed bracket 2 to enter the printer.

The adjustment component 3 includes two identical slide rails 5 for carrying the sliding of a slider 6. The two slide rails 5 are fixedly connected to the surface of the paper feed bracket 2 to provide support points for the operation of the slide rails 5. A slider 6 is slidably connected to the surface of the slide rail 5 to drive the sliding of a slide plate 7. The surface of the slider 6 is fixedly connected to a slide plate 7 to drive the sliding of a spring 10 and an adjustment plate 11. A slider 2 8 is fixedly connected to the surface of the slide plate 7 to cooperate with the slider 6 to drive the slide plate 7 to slide in the slide rail 2 9. The surface of the slider 2 8 is slidably connected to a slide rail 2 9 to carry the sliding of the slider 2 8. The slide rail 2 9 is fixedly connected to the surface of the paper feed bracket 2 to provide a support point for the operation of the slide rail 2 9.

The surface of the slide plate 7 is fixedly connected with three identical springs 10, which provide a buffering force for the adjustment plate 11 to guide and fix the paper, thereby preventing the two adjustment plates 11 from exerting too much force on the paper, making it difficult for the paper to enter the printer. The surface of the three springs 10 is fixedly connected with an adjustment plate 11, which is used to guide and fix the paper on the paper feed bracket 2.

A support plate 12 is fixedly connected to the surface of the slider 28 for driving the slider 28 to slide. A tooth groove 13 is provided on the surface of the support plate 12. A circular gear 14 is meshingly connected to the surface of the tooth groove 13. The rotation of the circular gear 14 can drive the movement of the support plate 12 under the action of the tooth groove 13. A connecting shaft 15 is fixedly connected to the surface of the circular gear 14. The rotation of the connecting shaft 15 can drive the rotation of the circular gear 14. One end of the connecting shaft 15 is slidably connected to the surface of the paper feed bracket 2. The other end of the connecting shaft 15 is fixedly connected to a rotating knob 16. Rotating the rotating knob can drive the rotation of the connecting shaft 15.

The user manually turns the rotary knob, which drives the connection shaft 15 to rotate. The rotation of the connection shaft 15 can drive the rotation of the circular gear 14. The rotation of the circular gear 14 can drive the movement of the two support plates 12, thereby driving the slider 28 to slide in the slide rail 29. The slider 28 can drive the slide plate 7 and the slide plate 16 to slide, thereby driving the spring 10 and the adjustment plate 11 on the surface of the slide plate 7 to guide the paper of different sizes to prevent the paper from tilting when entering the printer.

Embodiment 2:

The auxiliary component 4 includes a second connecting shaft 17, which provides a support point for the rotation of the pressing plate 18 after being pressed by the paper. The surface of the second connecting shaft 17 is slidably connected with the pressing plate 18, which is used to drive the movement of the rack 20. The two ends of the second connecting shaft 17 are fixedly connected to the surface of the paper feed bracket 2, providing a support point for the operation of the second rotating shaft. The surface of the pressing plate 18 is fixedly connected with a second spring 19. After the number of papers gradually decreases, the second spring 19 can restore the pressed pressing plate 18 to its original position. One end of the second spring 19 is fixedly connected to one end of the pressing plate 18, and the other end of the second spring 19 is fixedly connected to the surface of the paper feed bracket 2, providing a support point for the operation of the second spring 19.

The surface of the pressing plate 18 is fixedly connected to two identical racks 20 for driving the rotation of a circular gear 21. The surfaces of the two racks 20 are meshingly connected with a circular gear 21. The rotation of the circular gear 21 can drive the rotation of a connecting shaft 3 22. The surface of the circular gear 21 is fixedly connected to a connecting shaft 3 22. The rotation of the connecting shaft 3 22 can drive the rotation of a paper pickup roller 23. The surface of the connecting shaft 3 22 is fixedly connected to a paper pickup roller 23. The rotation of the paper pickup roller 23 can assist paper in entering the printer.

A square hole 24 matching the pickup roller 23 is provided on the surface of the pressing plate 18. Initially, the square hole 24 is located directly above the pickup roller 23 and is higher than the horizontal height of the pickup roller 23. When the pressing plate 18 is pressed downward, the square hole 24 falls to the vicinity of the pickup roller 23, and the pickup roller 23 is driven to rotate, thereby assisting the transmission of paper.

After the adjusting component 3 guides the paper, the gravity of the printed paper will cause the pickup roller 23 on the auxiliary component 4 to rotate, which can drive the bottom paper into the pickup wheel in the printer, preventing paper jams when the paper first enters the printer, thereby increasing the printing speed of the printer.
