Description

Technical Field

[0001] This utility model belongs to the field of printer technology, specifically relating to a paper heat dissipation device for printers. Background Technology

[0002] While printer paper itself doesn't require special heat dissipation measures, in certain situations, such as during printing, the paper may be affected by the printer's heat generation. During continuous high-volume printing, components inside the printer, such as the fuser assembly, continuously generate heat, which can be conducted to the paper, causing its temperature to rise. Additionally, in some high-speed printers, the paper's rapid movement and friction with internal components during fast printing can also lead to a temperature increase.

[0003] If the paper is not cooled down quickly, it will inevitably affect the quality of the print. For inkjet printers, high temperature will cause the paper fibers to expand, and the ink absorption and drying will be uneven, resulting in smudging and blurring of text and images.

[0004] Laser printers rely on high-temperature fusing. Overheating the paper can cause excessive toner fusing, resulting in jagged edges on the image and potentially damaging the paper's surface coating, affecting color reproduction and gloss. Therefore, after printing, the paper needs to be cooled down quickly to ensure print quality.

[0005] However, most printers currently available do not have a heat dissipation and cooling structure for the paper. After printing, the heat on the surface of the paper mainly relies on natural cooling, which takes a long time. If a large number of printed papers are stacked, the heat in the middle of the paper is not easy to dissipate, which will affect the printed content. Summary of the Invention

[0006] The purpose of this invention is to provide a paper cooling device for printers that can cool the paper on both sides during the paper feeding process, ensuring uniform heat dissipation and avoiding heat accumulation caused by uneven heat dissipation.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] A printer paper heat dissipation device includes a mounting plate with a U-shaped structure. Two hollow rollers are arranged on the inner side of the mounting plate. A rotating shaft is fixedly connected to each end of the two hollow rollers. The other end of the rotating shaft is rotatably connected to the mounting plate. A plurality of air outlet holes are opened on the side wall of the hollow rollers. A transmission component is arranged on the side wall of the mounting plate. The rotating shaft on the right side is hollow. An air supply component is arranged on the top surface of the mounting plate.

[0009] The transmission assembly includes a motor fixedly connected to the left side wall of the mounting plate. The output shaft of the motor is fixedly connected to one of the rotating shafts. Gears are fixedly connected to the side walls of the two rotating shafts on the right side, and the two gears mesh with each other.

[0010] The air supply assembly includes an air pump mounted on the top surface of the mounting plate. The output end of the air pump is fixedly connected to a guide pipe, and the guide pipe is connected to the right rotating shaft.

[0011] The right-side rotating shaft end face is rotatably connected to a connector, which is connected to the guide pipe.

[0012] Two L-shaped mating plates are fixedly connected to the top surface of the mounting plate.

[0013] The air outlets are arranged in a ring array.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model discloses a printer paper heat dissipation device. Through the cooperation of the mounting plate, hollow roller, transmission component and air supply component, the paper can be cooled on both sides after printing is completed and during the paper feeding process. This ensures uniform heat dissipation and avoids heat accumulation caused by uneven heat dissipation, which would affect the clarity of the printed content, thereby effectively improving its heat dissipation efficiency.

[0021] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-3As shown, a printer paper heat dissipation device includes a mounting plate 1, which has a U-shaped structure. Two hollow rollers 2 are arranged on the inner side of the mounting plate 1. The two ends of the two hollow rollers 2 are respectively fixedly connected to a rotating shaft 3. The other end of the rotating shaft 3 is rotatably connected to the mounting plate 1. Several air outlet holes 4 are opened on the side wall of the hollow rollers 2. A transmission component is arranged on the side wall of the mounting plate 1. The right rotating shaft 3 has a hollow structure. An air supply component is arranged on the top surface of the mounting plate 1.

[0023] like Figure 1 and Figure 2 As shown, the transmission assembly includes a motor 5 fixedly connected to the left side wall of the mounting plate 1. The output shaft of the motor 5 is fixedly connected to one of the rotating shafts 3. Gears 7 are fixedly connected to the side walls of the two rotating shafts 3 on the right side, and the two gears 7 mesh with each other. The transmission assembly is used to drive the hollow rollers 2 on both sides to rotate in opposite directions, so as to not only dissipate heat from the paper, but also to provide auxiliary conveying function for the paper, thereby effectively improving its heat dissipation effect.

[0024] like Figure 1 and Figure 2 As shown, the air supply assembly includes an air pump 8 mounted on the top surface of the mounting plate 1. The output end of the air pump 8 is fixedly connected to a guide pipe 9, and the guide pipe 9 is connected to the right rotating shaft 3.

[0025] Specifically, the air pump 8 is a miniature air pump, which is small in size and produces enough air supply for paper heat dissipation. Moreover, when dissipating paper heat, only one sheet of paper is cooled at a time. Therefore, uniform heat dissipation can be achieved through airflow.

[0026] like Figure 2 As shown, a connector 10 is rotatably connected to the end face of the right-side rotating shaft 3, and the connector 10 is connected to the guide tube 9. The use of connector 10 for connection allows for convenient docking with the guide tube 9, and also makes operation more convenient during later maintenance.

[0027] like Figure 1 As shown, two L-shaped mating plates 6 are fixedly connected to the top surface of the mounting plate 1. The mating plates 6 are used to fix the mounting plate 1 in a suitable position on the printer. The position, number, and angle of the mating plates 6 are not limited to those in this solution. Users can flexibly adjust them according to the size of the printer. Moreover, this connection method is a mature existing technology, so it will not be described in detail in this solution.

[0028] like Figures 1-3 As shown, the air outlets 4 are arranged in a ring array. When the airflow is evenly ejected from the air outlets 4, the airflow around the hollow roller 2 is in a uniform flow state, and the contact surface between the airflow and the paper is also in a uniform state, thereby improving the heat dissipation efficiency.

[0029] The working principle of this utility is as follows: First, the mounting plate 1 is fixed at the paper output position of the printer so that the gap between the two hollow rollers 2 corresponds to the paper output position of the printer. When it is necessary to dissipate heat from the paper, the motor 5 is started first. The output shaft of the motor 5 drives the upper hollow roller 2 to rotate through the rotating shaft 3. The upper hollow roller 2 drives the upper gear 7 to rotate. Since the upper gear 7 meshes with the lower gear 7, the two hollow rollers 2 rotate relative to each other to transport the paper.

[0030] At the same time, the air pump 8 is started, and the air pump 8 delivers airflow through the guide pipe 9 to the inside of the hollow roller 2. The airflow is discharged from the air outlet 4. When the paper passes through the hollow rollers 2 on both sides, the airflow blown out from both sides can be used to uniformly dissipate heat from the paper, effectively avoiding heat accumulation.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
