Description

Technical Field

[0001] This utility model belongs to the technical field of scanner paper tray structure, and in particular relates to a structure for improving the distortion of scanner paper tray. Background Technology

[0002] When feeding paper into the printer, the paper needs to be placed correctly in the paper tray with the printed side facing down. Align one end of the paper according to the arrow or label. Many types of printers will have corresponding icons or instructions to guide users on how to place the paper. For printers with multiple paper trays, each tray is usually marked as a different paper source, such as standard paper tray (number one).

[0003] Because the printer's paper tray is installed at an angle, the paper will move in the tilted direction. If there is a large amount of paper and it cannot be positioned, the paper may enter the printer at an angle, causing the printed pattern or text to be tilted. If a large amount of paper enters at once, it may cause a paper jam at the printer's paper feed, requiring manual cleaning, or it may also damage the printer. Utility Model Content

[0004] The purpose of this invention is to provide a structure that improves the distortion of the scanner's paper feed tray. By pulling the telescopic rod, the paper is placed on the rotating plate, and at the same time, the rotating block 2 is rotated so that the two moving plates are positioned according to the size of the paper and have an aligning effect. After positioning, the telescopic rod is released, and the pulley applies downward pressure to the paper to prevent the paper from falling all at once. This solves the problem that existing paper, when there are many pieces, cannot be positioned properly, which may cause the paper to enter the printer at an angle, resulting in tilted printed patterns or text. If a large number of pieces of paper enter at once, it may cause paper jams at the printer's paper feed.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a structure for improving the distortion of the paper feed tray in a scanner. It includes a printer, with a support rod fixedly connected to the right side of the printer. A support plate is fixedly connected to the top of the support rod, and a rotating plate is contacted at the top of the support plate. A telescopic rod is positioned above the rotating plate. A rotating hole is formed on the front of the rotating plate, and a small bidirectional threaded rod contacts the inner wall of the rotating hole. A second rotating block is fixedly connected to the front of the second rotating block, and a pulley is positioned above the second rotating block. A first movable block is threadedly connected to the outer surface of the second rotating block, and a movable plate is fixedly connected to the top of the first movable block. Specifically, by setting the second rotating block, the paper is placed on the rotating plate by pulling the telescopic rod, while simultaneously rotating the second rotating block. This allows the two movable plates to position the paper according to its size, achieving a sorting effect. After positioning, the telescopic rod is released, causing the pulley to apply downward pressure to the paper, preventing excessive paper drop at once. The pulley also makes paper extraction smoother, protecting the printer and facilitating paper positioning and sorting.

[0007] Furthermore, a baffle is fixedly connected to the top of the rotating plate, and a rotating rod is rotatably connected to the front of the rotating plate via a pin. A rotating rod is rotatably connected to the side of the rotating rod away from the rotating block via a pin. A fixing block is fixedly connected to the right side of the printer, and the fixing block is rotatably connected to the rotating rod via a pin. A rotating block is rotatably connected to the left side of the rotating plate via a pin. There are two baffles, symmetrically arranged around the telescopic rod. This invention, by setting the rotating rod, specifically the support rod, allows the support plate to support the bottom of the rotating plate. The setting of the rotating rod and the rotating rod itself restricts the rotation plate, reduces the impact of gravity on the rotating plate, prevents twisting or breakage, protects it, extends the service life of the device, and makes the device easy to fold, improving overall convenience.

[0008] Furthermore, a connecting post is fixedly connected to the bottom of the telescopic rod, a connecting rod is fixedly connected to the bottom of the connecting post, and a sliding block is fixedly connected to the bottom of the connecting rod. A rotating groove is formed on the inner wall of the sliding block, and the inner wall of the rotating groove is rotatably connected to the pulley via a pin. There are several sliding blocks arranged in a horizontal array. There are two connecting posts arranged symmetrically. A sliding hole is formed on the top side of the sliding block away from the pulley. The pulley can apply pressure to the paper while making the paper easier to pull out, effectively preventing the risk of paper jams caused by excessive paper falling.

[0009] Furthermore, a first moving groove is provided on the top of the rotating plate, and a limiting block is fixedly connected to the inner wall of the moving groove. A second moving groove is provided on the side of the top of the rotating plate away from the limiting block, and a sliding rod is fixedly connected to the inner wall of the moving groove. The second moving block is slidably connected to the outer surface of the sliding rod. The sliding rod can limit the second moving block and make the second moving block move more smoothly.

[0010] Furthermore, the inner wall of the movable plate is provided with a slot, and a fixed post is fixedly connected to the inner wall of the slot. A spring is sleeved on the outer surface of the fixed post, and the inner wall of the sliding hole contacts the outer surface of the fixed post. The spring allows the sliding block to be reset better under its action, and at the same time, it can also put pressure on the paper.

[0011] Furthermore, there are two connecting rods, which are symmetrically arranged around the limiting block. The bottom of the sliding block is in contact with the bottom of the inner wall of the sliding hole. The connecting rods can connect several sliding blocks so that they can move synchronously.

[0012] This utility model has the following beneficial effects:

[0013] This invention features a second rotating block. Specifically, by pulling a telescopic rod, paper is placed on a rotating plate. Simultaneously, rotating the second rotating block positions the paper according to its size on both moving plates, thus achieving a sorting effect. After positioning, the telescopic rod is released, allowing the pulleys to apply downward pressure to the paper, preventing excessive paper drop at once. Furthermore, the pulleys make paper extraction by the printer smoother, protecting the printer and facilitating paper positioning and sorting.

[0014] This utility model, by setting a first rotating rod, specifically a support rod, enables the support plate to support the bottom of the rotating plate. The setting of the second rotating rod and the first rotating rod also restricts the rotating plate and reduces the influence of gravity on the rotating plate itself, preventing it from twisting or breaking, thus protecting it and extending the service life of the device. In addition, the device is easy to store, improving the overall convenience of the device.

A pulley 331 is provided above the rotating block 4. A movable... Block 42 is a movable plate 5 fixedly connected to its top. This utility model uses a rotating block 4 to place the paper on the rotating plate 12 by pulling the telescopic rod 3. At the same time, rotating the rotating block 4 allows the two movable plates 5 to position the paper according to its size and to achieve a sorting effect. After positioning, the telescopic rod 3 is released, and the pulley 331 applies downward pressure to the paper to prevent the paper from falling too much at once. At the same time, the pulley 331 makes the printer pick up the paper more smoothly, protects the printer, and facilitates the positioning and sorting of the paper.

[0026] A baffle 2 is fixedly connected to the top of the rotating plate 12. A rotating rod 21 is rotatably connected to the front of the rotating plate 12 via a pin. A rotating rod 22 is rotatably connected to the side of the rotating rod 21 away from the rotating block 4 via a pin. A fixing block 221 is fixedly connected to the right side of the printer 1. The fixing block 221 is rotatably connected to the rotating rod 22 via a pin. A rotating block 23 is rotatably connected to the left side of the rotating plate 12 via a pin. There are two baffles 2, which are symmetrically arranged with the telescopic rod 3 as the center. By setting the rotating rod 21, specifically the support rod 11, the support plate 111 supports the bottom of the rotating plate 12. The rotating rods 22 and 21 restrict the rotating plate 12, reduce the influence of gravity on the rotating plate 12, prevent it from twisting or breaking, protect it, extend the service life of the device, and make the device easy to fold, thus improving the overall convenience of the device.

[0027] The bottom of the telescopic rod 3 is fixedly connected to a connecting post 31, the bottom of the connecting post 31 is fixedly connected to a connecting rod 32, the bottom of the connecting rod 32 is fixedly connected to a sliding block 33, the inner wall of the sliding block 33 is provided with a rotating groove, the inner wall of the rotating groove is rotatably connected to the pulley 331 through a pin, there are several sliding blocks 33, the several sliding blocks 33 are arranged in a horizontal array, there are two connecting posts 31, the two connecting posts 31 are arranged symmetrically, and the top of the sliding block 33 is provided with a sliding hole on the side away from the pulley 331.

[0028] The top of the rotating plate 12 has a first moving groove, and a limiting block 43 is fixedly connected to the inner wall of the moving groove. The top of the rotating plate 12 has a second moving groove on the side away from the limiting block 43. A sliding rod 44 is fixedly connected to the inner wall of the moving groove, and a second moving block 45 is slidably connected to the outer surface of the sliding rod 44.

[0029] The inner wall of the movable plate 5 has a slot, and a fixed post 52 is fixedly connected to the inner wall of the slot. A spring 51 is sleeved on the outer surface of the fixed post 52, and the inner wall of the sliding hole is in contact with the outer surface of the fixed post 52.

[0030] There are two connecting rods 32, which are symmetrically arranged with the limiting block 43 as the center. The bottom of the sliding block 33 is in contact with the bottom of the inner wall of the sliding hole.

[0031] A specific application of this embodiment is as follows: By pulling the telescopic rod 3 upward, the paper is placed on the rotating plate 12. At the same time, the rotating block 4 is turned, causing the small bidirectional threaded rod 41 to rotate and simultaneously driving the two moving blocks 42 to move in opposite directions. Since the moving plate 5 is fixed to the top of the moving block 42, it will simultaneously drive the two moving plates 5 to move in opposite directions until the paper is positioned, thus achieving a paper-aligning effect. Then, the telescopic rod 3 is released. Due to the spring 51, the connecting rod 32 drives several pulleys 331 to reset. The pulleys 331 then apply downward pressure to the paper, preventing the paper from falling too much at once and flattening it to prevent bending during movement. Then, the printer 1 can be started to extract the paper. Due to the support rod 11, the support plate 111 can support the bottom of the rotating plate 12, reducing the pressure of the paper on the rotating plate 12 and preventing it from twisting or being damaged. At the same time, since the rotating rod 22 and the rotating rod 11 are connected to the printer 1 and the baffle 2 through the fixing block 221, the rotating rod 22 and the rotating rod 11 exert a diagonal pulling force on the baffle 2, further reducing the pressure on the baffle 2, protecting the device and extending its service life. At the same time, rotating the baffle 2 in the direction of the printer will rotate the rotating rod 22 and the rotating rod 11 until the rotating plate 12 is closed, making the overall use of the device more convenient.
