Description

Technical Field

[0001] This utility model relates to the technical field of high-speed printer accessories, specifically a high-speed printer paper output table. Background Technology

[0002] The output table is one of the important components of a digital printer. Its main function is to feed the printed paper from the printer into the receiving table. For example, the utility model patent with announcement number CN201284160Y, entitled "Printing Machine Output Table", includes a frame, a conveyor belt, and a suction fan. The conveyor belt is set on the frame, and the suction fan is set at the bottom of the frame.

[0003] The paper output table typically has two sets of conveyor belts, with a suction module between them. Suction holes are evenly distributed on the suction module. When the suction fan draws air, it adheres the paper to the surface of the conveyor belts. Under the high-speed transmission of the conveyor belts, the paper is quickly fed into the receiving table. Due to the insufficient rigidity of the paper, the output paper speed varies, resulting in misalignment when the paper is fed into the receiving table, making it difficult to guarantee paper output stability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a paper output table for a high-speed printer that can improve the rigidity of paper so that the paper can be better aligned.

[0005] The technical solution of this utility model is to provide a high-speed printer output table with the following structure: including a frame, a conveying assembly disposed on the frame, and a suction fan disposed below the frame; the conveying assembly includes two conveyor belts, and the frame is provided with three suction modules evenly spaced along its width direction, with a gap adapted to the conveyor belt between adjacent suction modules, and the conveyor belt is disposed within the corresponding gap; the suction modules extend along the conveying direction of the conveyor belt, and the height of the upper surface of the suction module is lower than the height of the upper surface of the conveyor belt; a plurality of suction holes are evenly distributed on the suction module, penetrating its upper and lower ends, and the lower end of the suction hole is connected to the suction port of the suction fan.

[0006] With the above structure, the paper output table of the high-speed printer of this invention has the following advantages compared with the prior art:

[0007] This invention features three spaced-apart suction modules on a frame, with the upper surface of the suction modules lower than the upper surface of the conveyor belt. When the suction fan draws air, it adsorbs the paper onto the upper surface of the conveyor belt. Because the upper surface of the suction module is lower than the upper surface of the conveyor belt, the paper is bent into a W shape. This improves the rigidity of the paper, ensures the stability of the paper output, and also ensures that the paper is aligned when it enters the receiving table.

[0008] Preferably, each end of the frame is connected to a paper tray, and the frame is equipped with a spacing adjustment component that corresponds to each paper tray. The spacing adjustment component is used to adjust the spacing between the two paper trays. The spacing adjustment component can adjust the spacing between the two paper trays according to the size of the paper, thereby accommodating the paper output shape of different paper sizes and ensuring that the paper receiving table collects the paper neatly.

[0009] Preferably, the spacing adjustment assembly includes a fixing plate and a fastening bolt. The tray plate is connected to the fixing plate, and the fixing plate is slidably connected to a frame. The frame has a guide groove extending along its width and passing through its upper and lower ends. The connecting end of the fastening bolt passes through the guide groove from bottom to top and connects to the fixing plate. The spacing between the two tray plates can be easily adjusted by adjusting the positions of the two fixing plates on the frame. After adjusting the positions of the fixing plates, the fixing plates are then fixed by tightening the fastening bolt to prevent them from sliding.

[0010] Preferably, the conveying assembly further includes a drive motor mounted on the bottom of the frame. The drive wheels of the two conveyor belts are connected by a shaft, and the drive motor is driven by the shaft to drive the two conveyor belts to rotate synchronously. Using the same drive motor for both conveyor belts not only saves equipment costs but also ensures synchronous transmission of the two conveyor belts, preventing paper misalignment during transport.

[0011] Preferably, both ends of the shaft are connected to the frame via bearings. This reduces friction during shaft rotation, resulting in smoother shaft transmission.

[0012] Preferably, the bottom of the platform is provided with an air suction chamber that communicates with multiple air suction holes, and a cover plate with an opening is connected to the air suction chamber, with the air suction port of the blower connected to the opening of the cover plate.

[0013] Preferably, the stand, suction module, suction holes, and suction chamber are integrally molded. This reduces the number of processing steps and saves production costs. Attached Figure Description

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown;

[0023] This utility model discloses a paper output table for a high-speed printer: including a table frame 1, a conveying assembly 2 disposed on the table frame 1, and a suction fan 3 disposed below the table frame 1.

[0024] The conveying assembly 2 includes two conveyor belts 21. The platform 1 is provided with three suction modules 31 that are evenly spaced along its width direction. There is a gap between two adjacent suction modules 31 that is adapted to the conveyor belts 21. The conveyor belts 21 are set in the corresponding gaps. The suction modules 31 extend along the conveying direction of the conveyor belts 21, and the height of the upper surface of the suction modules 31 is lower than the height of the upper surface of the conveyor belts 21. Several suction holes 32 are evenly distributed on the suction modules 31, penetrating its upper and lower ends. The lower end of the suction holes 32 is connected to the suction port of the suction fan 3.

[0025] This invention features three spaced suction modules 31 on a frame 1, with the upper surface of the suction modules 31 positioned lower than the upper surface of the conveyor belt 21. When the suction fan 3 draws air, it adsorbs the paper onto the upper surface of the conveyor belt 21. Because the upper surface of the suction modules 31 is lower than the upper surface of the conveyor belt 21, the paper is bent into a W shape. This improves the rigidity of the paper, ensures the stability of the paper output, and also ensures that the paper is aligned when it enters the receiving table.

[0026] The two ends of the frame 1 are respectively connected to a paper tray 11. The frame 1 is provided with a spacing adjustment component 12 corresponding to the paper tray 11. The spacing adjustment component 12 is used to adjust the spacing between the two paper trays 11, so as to meet the paper output shape of different sizes of paper and ensure that the paper receiving table collects paper neatly.

[0027] The spacing adjustment assembly 12 includes a fixed plate 121 and a fastening bolt 122. The support plate 11 is connected to the fixed plate 121. The fixed plate 121 is slidably connected to the frame 1. The frame 1 is provided with a guide groove 13 that extends along its width direction and passes through its upper and lower ends. The connecting end of the fastening bolt 122 passes through the guide groove 13 from bottom to top and is connected to the fixed plate 121.

[0028] The distance between the two support plates 11 can be easily adjusted by adjusting the position of the two fixing plates 121 on the frame 1. After adjusting the position of the fixing plates 121, the fixing plates 121 can be fixed by tightening the fastening bolts 122 to prevent the fixing plates 121 from sliding.

[0029] The conveying assembly 2 also includes a drive motor 22 mounted on the bottom of the frame 1. The drive wheels of the two conveyor belts 21 are connected by a shaft 23, and the drive motor 22 is connected to the shaft 23 for driving the two conveyor belts 21 to rotate synchronously. The two conveyor belts 21 are driven by the same drive motor 22, which not only saves equipment costs but also ensures that the two conveyor belts 21 are driven synchronously, preventing the paper from shifting during conveying.

[0030] The two ends of the shaft 23 are connected to the frame 1 through bearings 24, which can reduce the friction when the shaft 23 rotates and make the shaft 23 rotate more smoothly.

[0031] The bottom of the stand 1 is provided with a suction chamber 33 that is connected to multiple suction holes 32. A cover plate 34 with an opening is connected to the suction chamber 33, and the suction port of the suction fan 3 is connected to the opening of the cover plate 34.

[0032] The stand 1, suction module 31, suction hole 32 and suction chamber 33 are integrally molded, which can reduce the processing steps of the product and save production costs.

[0033] The paper feed end of the paper output table is also equipped with an electrostatic brush holder 4, on which an electrostatic brush 5 is installed to remove static electricity and prevent paper from sticking together.

[0034] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope of the claims.
