Description

Technical Field

[0001] This utility model is a paper pressing structure for a printer, belonging to the field of printers. Background Technology

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed, and noise. There are many types of printers. According to whether the printing element strikes the paper, they are divided into impact printers and non-impact printers. According to the structure of the printed characters, they are divided into full-character printers and dot-matrix character printers. The paper clamping structure of a printer is a mechanism that presses the printing paper to make it flatter, thereby avoiding poor printing results caused by paper wrinkles.

[0003] In existing printer paper clamping structures, a paper receiving pad is used to press the paper edge. After clamping, a linear motor rail is activated, causing the smoothing rod to slide over the paper. The smoothing rod smooths out wrinkles on the paper surface. However, because paper has elasticity, after the smoothing rod presses over the wrinkles, there is a reset phenomenon, resulting in a small amount of wrinkles still remaining at the paper wrinkles, which affects the printing effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a paper pressing structure for a printer to solve the problems mentioned in the background art.

An electric heating roller is rotatably connected to the bottom of the lifting plate.

[0013] The beneficial effects of this utility model are:

[0014] A small amount of water is atomized and sprayed onto the paper surface through an atomizing nozzle. This results in a small amount of atomized moisture on the paper surface, slightly softening the wrinkles. Activating the micro push rod moves the lifting plate downwards, causing the heating roller to press the paper firmly. As the paper passes over the heating roller, the roller smooths and heats the paper surface, drying the small amount of atomized moisture and smoothing out the wrinkles.

[0024] Please see Figures 1-5This utility model provides a technical solution: a printer paper pressing structure, including a first mounting frame 1 and a second mounting frame 3.

The top of the conveying block 8 is provided with a conveying groove, and the inside of the conveying groove is provided with a conveyor belt body 9. The conveyor belt body 9 is an existing device. When the paper is on the conveyor belt body 9, the conveyor belt body 9 can convey the paper to the printing area.

[0027] Please see Figures 1-5 The conveying component includes a first motor 5 and a second motor 551. One side of both the first motor 5 and the second motor 551 is fixedly connected to the inner sidewall of the second mounting block 4. The output end of the first motor 5 is fixedly connected to a conveying rod 51 via a coupling. One end of the conveying rod 51 is fixedly connected to a first conveying roller 53. One end of the conveying rod 51 is rotatably sleeved with the second mounting block 4. A first gear 52 is fixedly sleeved on the outer wall of the conveying rod 51. A second gear 54 is meshed with one side of the first gear 52. A second conveying roller 55 is fixedly sleeved on one side of the second gear 54. One end of the second conveying roller 55 is rotatably sleeved with the second mounting block 4. Starting the first motor 5 can drive the conveying rod 51 and the first conveying roller 53 to rotate, which in turn can drive the second conveying roller 55 to rotate through the first gear 52 and the second gear 54, thereby conveying the paper.

[0028] Furthermore, the output end of the second motor 551 is fixedly connected to a rotating rod 552 via a coupling. One end of the rotating rod 552 is fixedly connected to a second rotating roller 556. The outer wall of the second rotating roller 556 is provided with a water outlet hole 63. A third gear 553 is fixedly sleeved on the outer wall of the rotating rod 552. A fourth gear 554 is meshed on one side of the third gear 553. A first rotating roller 555 is fixedly sleeved on one side of the fourth gear 554. A humidifying component is provided inside the second rotating roller 556. The second motor 551 drives the rotating rod 552 and the second rotating roller 556 to rotate, which in turn drives the first rotating roller 555 to rotate through the third gear 553 and the fourth gear 554. Thus, when the paper is in contact with the first rotating roller 555 and the second rotating roller 556, it can play an auxiliary role in conveying the paper, and in this process, the paper will be smoothed.

[0029] Specifically, the humidifying component includes a bearing 6 embedded in the inner wall of the second rotating roller 556.

A water inlet pipe 64 is rotatably sleeved on the inner wall of the second rotating roller 556. One end of the water inlet pipe 64 extends into the interior of the water spray pipe 61. The water inlet pipe 64 is rotatably connected to the water spray pipe 61. One end of the water inlet pipe 64 extends into the interior of the water tank 65. The water tank 65 is fixedly connected to the water inlet pipe 64. Water inside the water tank 65 enters the interior of the water spray pipe 61 through the water inlet pipe 64. Then, a small amount of water can be atomized and sprayed onto the paper surface through the atomizing nozzle 62. As a result, there will be a small amount of atomized water on the paper surface, and the wrinkled parts will soften slightly.

[0030] Specifically, the water inlet pipe 64 has an "L" shaped structure, and the top of the water injection pipe 66 is equipped with a sealing cap, so that the water inside the water tank 65 can enter the interior of the spray pipe 61 through the water inlet pipe 64.

[0031] Please see Figures 1-2 The drying and flattening component includes a support plate 7, one side of which is fixedly connected to one side of a water tank 65. A micro push rod 71 is fixedly connected to the bottom of the support plate 7, and a lifting plate 72 is fixedly connected to the push rod head of the micro push rod 71. An electric heating roller 73 is rotatably connected to the bottom of the lifting plate 72. The electric heating roller 73 can be electrically heated. Activating the micro push rod 71 can drive the lifting plate 72 to move downward, thereby causing the electric heating roller 73 to press the paper. When the paper passes through the electric heating roller 73, the electric heating roller 73 smooths and heats the surface of the paper, thereby drying the trace amount of atomized moisture on the surface of the paper, and heating and smoothing the wrinkled parts, thereby hardening the paper to a certain extent, and thus preventing the wrinkled parts from returning to their original position.

[0032] Working principle: The first motor 5 can drive the conveying rod 51 and the first conveying roller 53 to rotate, which in turn drives the second conveying roller 55 to rotate through the first gear 52 and the second gear 54, thereby conveying the paper. The second motor 551 drives the rotating rod 552 and the second rotating roller 556 to rotate, which in turn drives the first rotating roller 555 to rotate through the third gear 553 and the fourth gear 554. Thus, when the paper is in contact with the first rotating roller 555 and the second rotating roller 556, it can play an auxiliary role in conveying the paper, and in this process, the paper will be smoothed out.

[0033] Water is injected into the water tank 65 through the water injection pipe 66. The water inside the water tank 65 can enter the spray pipe 61 through the water inlet pipe 64. A small amount of water can be atomized and sprayed onto the paper surface through the atomizing nozzle 62. As a result, there will be a small amount of atomized water on the paper surface, and the wrinkled parts will soften slightly. Activating the micro push rod 71 can drive the lifting plate 72 to move downward, thereby causing the heating roller 73 to press the paper. When the paper passes through the heating roller 73, the heating roller 73 smooths and heats the surface of the paper, thereby drying the small amount of atomized water on the paper surface, and the wrinkled parts will be heated and smoothed, thereby hardening the paper to a certain extent, and the wrinkled parts will no longer return to their original position.
