Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and particularly relates to a paper outlet tray of a printer for preventing blockage. Background Art

[0002] A printer is one of the output devices of a computer, and is used to print the processing results of the computer on relevant media. An inkjet printer is one of them. An inkjet printer uses an inkjet head to guide tiny ink droplets to set positions, so as to spray patterns and characters on other media.

[0003] The printed paper will be output from the paper outlet to the tray. Once the user does not take out the printed paper in time, the paper is likely to accumulate at the paper outlet. When too much paper accumulates, it will affect the discharge of subsequent paper, resulting in the printer being unable to work properly. In addition, the paper will also accumulate under the print head, causing friction between the print head and the paper. These frictions will damage the needles of the print head, making it unable to spray ink correctly, and further resulting in the printer being unable to print normally.

[0004] Therefore, a paper outlet tray of a printer for preventing blockage is proposed. Content of the Utility Model

[0026] Such as Figures 1 to 5As shown in the figure, a paper outlet tray for a printer that prevents blockage includes a fixed frame 1. A tray assembly 2 is arranged on the surface of the fixed frame 1. A bottom box 3 is fixedly connected to the bottom surface of the fixed frame 1. An L-shaped placement plate 4 is slidably connected to the inner wall of the bottom box 3. A pressing assembly 5 for limiting the paper is arranged on the right side wall of the bottom box 3. An auxiliary paper feeding assembly 6 is arranged on the rear side wall of the bottom box 3. More specifically, the fixed frame 1 is fixedly installed at the paper outlet of the printer through bolts. The printed paper is continuously output from the paper outlet, and the paper will continuously stack on the surface of the tray assembly 2. When the tray assembly 2 detects that the stacked paper reaches the preset weight, it will rotate downward, so that the right end of the paper slides into the inside of the L-shaped placement plate 4. The right end of the paper is pressed by the pressing assembly 5, and then the auxiliary paper feeding assembly 6 operates to press down the paper, so that the part of the paper staying on the surface of the tray assembly 2 also falls into the inside of the L-shaped placement plate 4. Then the printed paper can be collected by the L-shaped placement plate 4, and the L-shaped placement plate 4 can be pulled forward to take out the paper.

[0027] The tray assembly 2 includes a motor 201, and the motor 201 is fixedly installed on the surface of the fixed frame 1. The output end of the motor 201 is fixedly connected to a rotating shaft 202. A supporting plate 203 is fixedly connected to the surface of the rotating shaft 202. A first pressure sensor 204 is arranged on the surface of the supporting plate 203. It should be noted that the paper output from the paper outlet will move to the surface of the first pressure sensor 204. The paper continuously stacks, and the first pressure sensor 204 is used to detect the weight of the paper. When the detected stacked weight reaches the preset value, the motor 201 operates to drive the rotating shaft 202 to rotate, thereby driving the supporting plate 203 to rotate downward, so that the paper on the surface of the supporting plate 203 can slide downward into the inside of the L-shaped placement plate 4.

[0028] The pressing assembly 5 includes a first electric push rod 501, and the first electric push rod 501 is fixedly installed on the right side surface of the bottom box 3. The telescopic end of the first electric push rod 501 is fixedly connected to a connecting plate 502. A fixed seat 506 is fixedly connected to the bottom surface of the connecting plate 502. A support rod 503 is movably inserted into the inner wall of the fixed seat 506. A pressing plate 504 is fixedly connected to the end of the support rod 503. A chute 505 is formed through the right side surface of the bottom box 3, and the inner wall of the chute 505 is slidably connected to the surface of the support rod 503. A second pressure sensor 507 is fixedly installed on the top of the inner wall of the fixed seat 506. More specifically, through the operation of the first electric push rod 501, the connecting plate 502 is driven to move downward, thereby pulling the support rod 503 to slide along the inner wall of the chute 505, so that the pressing plate 504 descends and presses on the right end of the paper, preventing the paper from slipping when the auxiliary paper feeding assembly 6 pushes the paper, so that the paper can be stacked neatly. The second pressure sensor 507 can detect the pressure of the pressed paper to ensure that the paper is pressed with an appropriate pressure.

[0029] The auxiliary paper feeding component 6 includes a second electric push rod 601, and the second electric push rod 601 is fixedly installed on the back surface of the bottom box 3. The telescopic end of the second electric push rod 601 is fixedly connected to a connecting rod 602, and the end of the connecting rod 602 is fixedly connected to a slider 603. A limiting groove 604 is formed through the back surface of the bottom box 3, and the inner wall of the limiting groove 604 is slidably connected to the surface of the slider 603. A roller 605 is rotatably connected to the front surface of the slider 603. It should be noted that by operating the second electric push rod 601, the connecting rod 602 is driven to move, thereby pushing the slider 603 to move along the inner wall of the limiting groove 604, which can drive the roller 605 to move. By pushing the paper downward with the roller 605, the part of the paper staying on the surface of the pallet component 2 can be pressed into the L-shaped placing plate 4, so as to ensure that the paper completely enters the L-shaped placing plate 4.

[0030] The second electric push rod 601 is inclined towards the lower left. More specifically, by arranging the second electric push rod 601 obliquely, the roller 605 can be controlled to move towards the lower left, and then the part of the paper remaining on the surface of the pallet component 2 can be pushed into the L-shaped placing plate 4.

[0031] A baffle is fixed to the right side of the top surface of the fixed frame 1. It should be noted that by arranging the baffle, the right side of the paper is limited, preventing the paper from moving onto the surface of the fixed frame 1, thus affecting the accuracy of the pressure detected by the first pressure sensor 204.

[0032] In summary: The fixed frame 1 is fixedly installed at the paper outlet of the printer through bolts. The printed paper is continuously output from the paper outlet and will be continuously stacked on the surface of the pallet component 2. When the pallet component 2 detects that the stacked paper reaches the preset weight, it will rotate downward, causing the right end of the paper to slide into the L-shaped placing plate 4. The right end of the paper is pressed tightly by the pressing component 5, and then the auxiliary paper feeding component 6 operates to press down the paper, so that the part of the paper staying on the surface of the pallet component 2 also falls into the L-shaped placing plate 4. Then the printed paper can be collected by the L-shaped placing plate 4, and the paper can be taken out by pulling the L-shaped placing plate 4 forward. In use, it realizes the effect of facilitating the automatic feeding and storage of the stacked paper at the paper outlet of the printer, avoiding the situation that the paper accumulates at the paper outlet and affects the normal operation of the printer, thus ensuring the smooth operation of the printer.
