[0038] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0039] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0040] Please refer to Figures 1-3 This embodiment provides a speed measuring module 100, which includes a speed measuring bracket 110, a speed measuring plate 120, a transmission belt 130, and at least two speed measuring gears 140 with different radii.

[0041] The speed measuring plate 120 is connected to the speed measuring bracket 110, and the speed measuring plate 120 is equipped with a speed measuring viewing area 121; all speed measuring gears 140 are rotatably connected to the speed measuring bracket 110, and all speed measuring gears 140 are spaced apart and located on the same side of the speed measuring plate 120; the transmission belt 130 is in transmission cooperation with all speed measuring gears 140, and one of the speed measuring gears 140 is used for transmission connection with the paper feeder;

[0042] All speed measuring gears 140 have a speed measuring mark 141 that is off-axis on the side near the speed measuring plate 120, and the rotation path of the speed measuring mark 141 on each speed measuring gear 140 passes through the speed measuring perspective area 121.

[0043] It should be noted that when configuring speed measuring mark 141, it can be set as a colored dot for easier observation.

[0044] Please refer to Figures 1-3 The working principle of the speed measuring module 100 is as follows:

[0045] The speed measurement module 100 is used in the paper feeder. Its purpose is to determine the actual paper feeding speed of the paper feeder and compare it with its theoretical speed during operation. This allows users or maintenance personnel to quickly determine whether there is an error in the paper feeding speed, so as to quickly identify the problem with the paper feeder and thus improve the efficiency and cost of maintenance.

[0046] Specifically, the speed measuring module 100 includes a speed measuring bracket 110, a speed measuring plate 120, a transmission belt 130, and at least two speed measuring gears 140 with different radii. All speed measuring gears 140 are rotatably connected to the speed measuring bracket 110, and are spaced apart and located on the same side of the speed measuring plate 120. The transmission belt 130 engages with all speed measuring gears 140, and one speed measuring gear 140 is connected to the paper feeder. The purpose is to ensure that during the operation of the paper feeder, power is transmitted from one speed measuring gear 140 to all speed measuring gears 140 via the transmission belt 130, enabling all speed measuring gears 140 to move in tandem. Furthermore, since the radii of each speed measuring gear are different and they do not directly contact each other, the linear velocities of each speed measuring gear 140 are different.

[0047] In addition, the speed measuring plate 120 is connected to the speed measuring bracket 110, and the speed measuring plate 120 is equipped with a speed measuring viewing area 121; and all the speed measuring gears 140 have a speed measuring mark 141 off-axis on the side near the speed measuring plate 120, and the rotation path of the speed measuring mark 141 on each speed measuring gear 140 passes through the speed measuring viewing area 121. Since the speed measuring viewing area 121 is provided on the speed measuring plate 120, and the speed measuring gears 140 are provided with speed measuring marks 141, and the rotation path of the speed measuring mark 141 on each speed measuring gear 140 passes through the speed measuring viewing area 121, during the operation of the paper feeder, one of the speed measuring gears 140 in the speed measuring module 100 will be driven to rotate, and then all the gears will be driven to rotate under the action of the transmission belt 130; thus, during the rotation of the gears, the speed of the paper feeder can be quickly determined by observing the number of visible speed measuring marks 141 in the speed measuring viewing area 121.

[0048] This speed measurement method utilizes the principle of visual persistence, linking multiple speed measuring gears 140 with different radii with the toothed belt of the paper feeder. Through the speed measuring viewing area 121 on the speed measuring plate 120, the number of speed measuring marks 141 on the continuously visible speed measuring gears 140 can be counted, thereby obtaining the actual rotation speed of the paper feeder, so as to determine whether the actual speed of the paper feeder has reached the requirement.

[0049] Therefore, the speed measuring module 100 is applied in the paper feeder, which can quickly measure the actual speed of the paper feeder, and thus make it easier to determine whether the actual speed matches the set theoretical speed. This makes it easier for maintenance personnel to perform maintenance, thereby improving maintenance efficiency and reducing maintenance costs.

[0050] Further, please refer to Figures 1-3In this embodiment, the speed measuring gear 140, which is used for transmission connection with the paper feeder, is provided with a first portion 142 and a second portion 143 along its axis. The first portion 142 is driven and engaged with the transmission belt 130, and the second portion 143 is used for transmission connection with the toothed belt of the paper feeder. That is, the speed measuring module 100 uses a method in which one of the speed measuring gears 140 meshes with the toothed belt in the paper feeder to achieve the transmission function.

[0051] Based on the above structure, when configuring the speed measuring perspective area 121, its purpose is to facilitate users or maintenance personnel to determine the speed of the paper feeder by observing the number of speed measuring marks 141 located in the speed measuring perspective area 121. Specifically, the speed measuring perspective area 121 includes a plurality of first speed measuring perspective holes 122 opened on the speed measuring plate 120. The axes of the plurality of first speed measuring perspective holes 122 are parallel and spaced apart from each other.

[0052] Each speed measuring gear 140 corresponds to a first speed measuring through hole 122, and the rotation path of the speed measuring mark 141 on each speed measuring gear 140 passes through the corresponding first speed measuring through hole 122.

[0053] Based on the above-mentioned setting of the speed measuring perspective area 121 as multiple first speed measuring perspective holes 122, and each speed measuring gear 140 corresponding to a first speed measuring perspective hole 122, the aperture size of each first speed measuring perspective hole 122 can be made consistent with the size of the corresponding speed measuring mark 141, so that the speed measuring mark 141 can be more clearly seen during the observation process.

[0054] Furthermore, in order to improve the accuracy of the observation process, the distance from the speed measuring mark 141 on the speed measuring gear 140 to its axis can be the first distance, and the distance from the first speed measuring through hole 122 to the axis of its corresponding speed measuring gear 140 can be the second distance, with the first distance and the second distance being the same.

[0055] Further, please refer to Figures 1-3 In this embodiment, when configuring the speed measuring gear 140, the number of speed measuring gears 140 can be adjusted to adapt to the speed measuring requirements of different paper feeders. Based on this, this embodiment can adopt a setting method in which the speed measuring module 100 includes three speed measuring gears 140 (the three speed measuring gears 140 are A, B and C respectively). Thus, when the above-mentioned setting method of configuring the first test viewing hole is adopted, three first speed measuring viewing holes 122 (the three first speed measuring viewing holes 122 are D, E and F respectively) are opened on the speed measuring plate 120, and each first test viewing hole corresponds to one test gear.

[0056] Based on the above configuration, in this embodiment, the three speed measuring gears 140 are arranged in a triangular pattern. Correspondingly, the three first speed measuring through holes 122 are also arranged in a triangular interval to match the configuration of the three speed measuring gears 140.

[0057] Unlike the aforementioned arrangement of three speed-measuring gears 140 arranged in a triangle, other embodiments of this utility model are described below. Figure 4 When the speed measuring module 100 includes three speed measuring gears 140, the three speed measuring gears 140 are also arranged at intervals along a preset direction. Therefore, based on different arrangement methods of the speed measuring gears 140, that is, based on the three speed measuring gears 140 being arranged at linear intervals, the speed measuring perspective area 121 can include three second speed measuring perspective holes 123 arranged at intervals along a preset direction (the three second speed measuring perspective holes 123 are H, I, and J, respectively). Moreover, each speed measuring gear 140 corresponds to one second speed measuring perspective hole 123, and the rotation path of the speed measuring mark 141 on each speed measuring gear 140 passes through the corresponding second speed measuring perspective hole 123. That is, through the above-mentioned arrangement method, the speed measuring module 100 can arrange the three speed measuring gears 140 at intervals along a preset direction, and the three second speed measuring perspective holes 123 can be arranged at intervals along a preset direction, thereby corresponding to the arrangement method of the speed measuring gears 140.

[0058] In addition, please refer to Figure 5 When the speed measuring module 100 includes three speed measuring gears 140, and the three speed measuring gears 140 are arranged sequentially at intervals along a preset direction, the speed measuring perspective area 121 is a strip-shaped hole 124 extending along the preset direction.

[0059] In summary, based on the above-mentioned arrangement of the test gears and the speed measuring perspective area 121, it can be seen that the hole shape and distribution of the speed measuring perspective area 121 can be appropriately adjusted according to the arrangement of multiple test gears. For example, when the three test gears are arranged in a triangle, the speed measuring perspective area 121 can be three first speed measuring perspective holes 122 arranged in a triangle; when the three test gears are arranged linearly at intervals along a preset direction, the speed measuring perspective area 121 can be three second speed measuring perspective holes 123 arranged at intervals along the same direction, or it can be a strip hole 124 extending along the same direction.

[0060] Further, please refer to Figures 1-3 To improve the stability of the linkage process of multiple speed measuring gears 140, the speed measuring module 100 includes a tensioning wheel 150 that contacts the transmission belt 130.

[0061] Based on the above, it can be seen that the speed measuring module 100 provided in this embodiment can adjust the number of its speed measuring gears 140 and the style of the corresponding speed measuring transparent area 121 according to the corresponding paper feeder.

[0062] Based on this, please refer to Figures 1-9 In practical applications, we take the paper feeder of the printer with three theoretical speed values ​​of 200mm / s, 300mm / s and 400mm / s as examples.

[0063] The speed measuring module 100 includes three speed measuring gears 140, the radius ratio of the three speed measuring gears 140 is 1:1.5:2, and the speed measuring transparent area 121 adopts the setting of three first transparent holes; on this basis, the speed measuring module 100 is fixed on the paper feeder, and one of the speed measuring gears 140 contacts the toothed belt of the paper feeder.

[0064] like Figure 7 As shown, when the theoretical speed of the paper feeder is set to 200 mm / s, the number of speed measuring marks 141 that can be observed through the speed measuring plate 120 of the speed measuring module 100 is 1.

[0065] like Figure 8 As shown, the number of speed measuring marks 141 observed is 2;

[0066] like Figure 9 As shown, when the theoretical speed of the paper feeder is set to 400 mm / s, the number of speed measuring marks 141 that can be observed through the speed measuring plate 120 of the speed measuring module 100 is 3.

[0067] Therefore, if the actual rotational speed of the paper feeder, determined by the number of observed speed measuring marks 141, is inconsistent with the theoretical rotational speed of the paper feeder, it indicates that the paper feeder has a paper feeding speed error and needs to be adjusted. Thus, it can quickly measure the actual rotational speed of the paper feeder, thereby facilitating the determination of whether its actual rotational speed matches the set theoretical rotational speed. This makes it easier for maintenance personnel to perform maintenance, thereby improving maintenance efficiency and reducing maintenance costs.

[0068] Based on the above, this embodiment also provides a paper feeder, which includes the speed measuring module 100 as described above. Therefore, by employing the speed measuring module 100, the paper feeder can quickly measure its actual rotational speed, thus facilitating the determination of whether its actual rotational speed matches the set theoretical speed. This makes it easier for maintenance personnel to perform maintenance, thereby improving maintenance efficiency and reducing maintenance costs.

[0069] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
