[0028] like Figure 1 , 2 As shown, an adaptive paper bridge device 1000 includes a printer bridge device 1010 and a paper feed bridge device 1020; the first output end 1500 of the printer bridge device 1010 is detachably connected to the second input end of the paper feed bridge device 1020, and the paper in the printer paper outlet passes through the printer bridge device 1010 and the paper feed bridge device 1020 for output and printing; a channel selection mechanism is provided at the front end of the paper feed bridge device 1020 to transport papers of different sizes or types to different channels.

[0029] In this embodiment, the adaptive paper bridge device 1000 in the present application includes a printer bridge device 1010 and a paper feed bridge device 1020. It should be noted that the printer bridge device 1010 is fixed to the printer, and the paper feed bridge device 1020 is fixed to the binder. The two can be detachably connected. There is no specific limitation. The first output end 1500 of the printer bridge device 1010 and the second input end of the paper feed bridge device 1020 are detachably connected; preferably, the printer bridge device 1010 and the paper feed bridge device 1020 are seamlessly overlapped to prevent gaps at the connection, paper jams, and affect subsequent printing work. It should be supplemented that the first input end 1200 of the printer bridge device 1010 is connected to the printer paper outlet, and the second output end of the paper feed bridge device 1020 is connected to the binder. The channel selection mechanism is arranged at one end adjacent to the printer bridge device 1010. The channel selection mechanism can transport the paper to different channels according to the type and size of the paper.

[0030] like Figure 1 , 3As shown, specifically, the specific structure of the printer bridge device 1010 includes a first input end 1200, a conveying part 1300, a first output end 1500 and support plates 1100 on both sides; wherein the first input end 1200 includes a paper feed baffle 1210, a paper feed bottom plate 1220 and one end of the support plate 1100 connecting the two on both sides; the first output end 1500 includes a paper discharge baffle, a paper discharge bottom plate and the other end of the support plate 1100 connecting the two on both sides.

[0031] Furthermore, the specific structure of the paper feed bridge device 1020 includes an upper plate 1600, a lower plate and side plates connecting the two on both sides; it should be additionally explained here that the end of the overall structure formed by the upper plate 1600, the lower plate and the side plates adjacent to the printer bridge device 1010 is the second input end, and the end away from the printer bridge device 1010 is the second output end. The upper plate 1600 includes a guide shaft 1610, a guide piece 1620, a coupling, a rotating electromagnet 1630, and a driven transmission assembly; the guide shaft 1610 is arranged on the side plate at one end connected to the printer bridge device 1010; the guide piece 1620 is fixedly connected to the guide shaft 1610, and the guide piece 1620 is suitable for matching with the opening structure 1530; the rotating electromagnet 1630 is connected to one end of the guide shaft 1610 through a coupling, and the rotating electromagnet 1630 is fixedly installed on the side plate, and the rotating electromagnet 1630 can drive the guide shaft 1610 and the guide piece 1620 to rotate within a preset angle; the driven assembly is arranged in the middle of the upper plate 1600; the lower plate is provided with a motor 1640 and an active transmission assembly, and the upper plate 1600 and the lower plate cooperate to complete the paper conveying. By installing a channel selection mechanism on the paper feed bridge device 1020, different types of paper can be classified and transported, mainly into cover paper and text paper, which solves the need to separate the two manually or in other ways in the later stage, simplifies the process of the printing process, and effectively improves the overall printing efficiency. It should also be pointed out that the shape of the guide plate 1620 only needs to be able to guide the paper normally and ensure that the paper can be smoothly transported in the upper and lower channels. It should be pointed out here that the specific structure of the upper channel and the lower channel can be in many ways. This article only gives a relatively simple solution. A partition can be installed between the upper plate 1600 and the lower plate to block and distinguish the upper and lower channels. Those skilled in the art can also choose a more complex solution as long as it is reasonable. It will not be elaborated in this article.

[0032] Specifically, the channel selection mechanism in the embodiment of the present application only lists a mechanism that guides and selects paper by rotating the electromagnet 1630 to drive the guide shaft 1610, but the present application should not be limited to this. Implementers in this field can select other guide structures from the existing technology, so they will not be repeated in this article.

[0033] Preferably, the guide plate 1620 is quasi-triangular, and the longest side of the triangle is concave inward with a certain arc. Compared with the triangular guide plate 1620, the concave arc is more conducive to the transportation of paper than the straight line. Moreover, the corner with the largest angle of the quasi-triangle is the connection point fixedly connected to the guide shaft 1610, ensuring that its connection structure is stable and extending the service life of the device of the present application.

[0034] In one specific embodiment, the channel selection mechanism is a rotatable mechanism, which can transport the paper to different channels arranged in upper and lower layers by rotating at different angles, and the number of channels is two, the upper channel is the printer body paper feeding channel, and the lower channel is the printer cover paper feeding channel. The rotatable mechanism includes a guide shaft 1610 and a guide plate 1620; the guide plate 1620 is fixedly connected to the guide shaft 1610, and is used to limit the transmission direction of the paper, and the guide plate 1620 can rotate up and down with the guide shaft 1610.

[0035] In this embodiment, the channel selection mechanism can be rotated up and down, and can only be rotated to a certain angle to ensure that the paper can smoothly enter the upper and lower layered channels.

[0036] In one specific embodiment, the paper feed bridge device 1020 also includes a coupling and a rotating electromagnet 1630, the rotating electromagnet is controlled by a PLC, a coupling is provided at one end of the guide shaft 1610, the rotating electromagnet 1630 is connected to the guide shaft 1610 via the coupling, and the PLC and the rotating electromagnet 1630 are electrically connected.

[0037] like Figure 3 As shown, in this embodiment, the rotating electromagnet 1630 is installed at one end of the guide shaft 1610, and the two are connected and fixed by a coupling therebetween. It should also be noted that an electromagnetic relay is electrically connected between the rotating electromagnet and the PLC. Since the cover paper is usually the first page, the PLC only requires technical personnel in the field to compile a program in advance, and the rotating electromagnet can complete the rotation within a preset angle according to the instructions of the PLC and processed by the electromagnetic relay. Generally, the preset angle should be rotated at least 90° clockwise and counterclockwise to effectively play a guiding role.

[0038] like Figure 1-3 As shown, more specifically, the workflow of this application is divided into two types:

[0039] 1. The cover paper coming out of the printer paper outlet enters the printer bridge device 1010 from the first input end 1200, and is then transported to the first output end 1500 through the transport unit 1300. At this time, the rotating electromagnet 1630 starts to rotate from the preset position according to the preset instruction of the PLC, and the guide shaft 1610 drives the guide plate 1620 to rotate at a preset angle. The cover paper enters the paper feed bridge device 1020 from the second input end, is guided to the lower channel according to the guiding action, and continues to be transported from the second output end to the subsequent binder, and the rotating electromagnet 1630 returns to the preset position according to the preset instruction of the PLC.

[0040] 2. The text paper coming out of the printer paper outlet enters the printer bridge device 1010 from the first input end 1200, and is then transported to the first output end 1500 through the transport unit 1300. The rotating electromagnet 1630 is always in a preset position. The text paper enters the paper feed bridge device 1020 from the second input end, is guided to the upper channel according to the guiding action, and is continuously transported from the second output end to the subsequent binder.

[0041] In one specific embodiment, the first input end and the first output end are connected via a first conveying portion, the height of the first input end is higher than the front end height of the first conveying portion, and the rear end height of the first conveying portion is higher than the height of the first output end.

[0042] In this embodiment, by setting the first input end, the first conveying unit connection, and the first output end with gradually decreasing heights, the paper can be conveyed smoothly without obstruction, thereby solving the paper jam problem.

[0043] In one specific embodiment, an opening structure 1530 is provided on the first output end 1500 of the printer bridge device 1010 , and the guide plates 1620 can move up and down in the opening structure 1530 , and the number of the opening structures 1530 and the number of the guide plates 1620 correspond one to one.

[0044] Specifically, the guide shaft 1610 and the guide plate 1620 are welded and formed, and one side of the shaft is connected to the rotating electromagnet 1630 by a coupling. The rotating electromagnet 1630 is fixedly mounted on the side plate to realize the paper adaptive feeding function. The guide plate 1620 and the printer bridge paperboard are seamlessly overlapped: the guide plate 1620 is inserted into the opening structure 1530 of the paper output bottom plate and the paper output baffle, and can overlap 3-5mm; to ensure smooth passage of paper. The guide plate 1620 can automatically reverse according to the input requirements of the paper. When the cover paper is fed, the rotating electromagnet 1630 is activated, the guide plate 1620 is tilted upward, the cover paper is guided downward, and the paper is transported downward; when the main text is fed, the rotating electromagnet 1630 returns to its original position, the upper end of the guide plate 1620 is flush with the main text feeding bottom plate 1220, and the paper is input to the binder in parallel. The guide plate in the prior art is a sheet metal with a fixed arc and cannot be adjusted.

[0045] In one specific embodiment, opposing-type sensors are disposed on the upper and lower parts of the paper feed bridge device 1020 .

[0046] In this embodiment, the upper and lower plates are equipped with through-beam sensors to monitor the number of pages passing through and count them accurately. The original solution was a fiber optic sensor, which was not sensitive to dark-colored paper and sometimes could not detect it, but this was not the case with the through-beam sensor.

[0047] In one specific embodiment, a driven wheel and a driven shaft are arranged in the middle of the conveyor belt 1310; the driven shaft is arranged on the inner side of the support plate 1100, and the driven wheel is arranged between the driving wheels at both ends; and a tensioning adjustment plate is installed on the driven wheel, and a long hole 1320 is opened at the corresponding position of the large bottom plate.

[0048] In this embodiment, a tensioning adjustment plate is provided, and the hole opened is a long hole 1320, which can provide more installation space for implementers in this field during assembly, and is convenient for implementers to make adjustments when adjustments are needed later.

[0049] like Figure 1 As shown, in one of the specific embodiments, rotating shafts are arranged on both sides of the paper feed baffle 1210, a rotating shaft groove is arranged on the support plate 1100, and a plurality of gears are preset in the rotating shaft groove, and the paper feed baffle 1210 has a preset movable range.

[0050] In this embodiment, in order to adapt to and dock with various types of printer paper outlets, a paper feed baffle 1210 that can be finely adjusted up and down is provided so that it can be adjusted to a suitable position and paper jam is not easy to occur.

[0051] In one specific embodiment, the first input end 1200 and the first output end 1500 are connected through the first conveying part 1300, and the second input end and the second output end are connected through the second conveying part 1300; a first motor is arranged on one side of the first conveying part 1300; a second motor is arranged on one side of the second conveying part 1300; the second conveying part 1300 includes a second transmission shaft and a pickup roller; the second transmission shaft is arranged at the rear end of the channel selection mechanism and is transmission-connected with the second motor, the pickup roller is installed on the driving shaft, and the paper is transported out of the channel through the pickup roller; the first motor and the second motor are both electrically connected to the PLC. The first conveying part 1300 includes a first transmission shaft, a transmission belt, a driven shaft and a driven wheel; the first transmission shaft is transmission-connected with the first motor, the number is two, and they are respectively arranged at both ends of the first conveying part 1300, the transmission belt is sleeved on the first transmission shaft, the driven shaft is arranged between the two first transmission shafts, the driven wheel is installed on the driven shaft, and a tensioning adjustment sheet is installed on the driven wheel to adjust the tightness of the conveyor belt.

[0052] like Figure 1As shown, in one of the specific embodiments, it also includes a cover plate 1400, which is covered on the conveying part 1300, and the cover plate 1400 is movably connected to the conveying part 1300. A paper pickup wheel is arranged on the cover plate 1400, and the paper pickup wheel and the transmission belt are located on the same straight line.

[0053] like Figure 2 As shown, in this embodiment, a conveying part 1300 with a matching structure is covered on the conveying structure, and the cover plate 1400 can press the paper well by its own weight, so that the paper is not easily offset during conveyance, or floats out of the work process with the surrounding air flow during conveyance. The paper pickup wheel and the conveyor belt 1310 on the conveying part 1300 work together. At the same time, the cover plate 1400 protects the top of the conveying process, reduces the influence of the external environment on the paper during conveyance, and improves the rationality of the adaptive paper bridge device 1000 of the present application.

[0054] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
