Description

Technical Field

[0001] This utility model relates to the field of paper stacking equipment technology, and in particular to a paper conveying and stacking mechanism. Background Technology

[0002] In industries such as paper processing, printing, and packaging, paper stacking mechanisms are key equipment for achieving automated production. Their core function is not only to stably transport paper to the palletizing and sorting stages, but also to ensure that the paper maintains a neat arrangement before palletizing, thereby improving the efficiency and quality of subsequent palletizing. Traditional paper stacking mechanisms typically employ a single conveyor channel design, where paper, after being cut, is directly transported along a fixed path to the stacking station; these mechanisms suffer from the following technical bottlenecks:

[0003] Lack of automatic alignment: Existing stacking mechanisms rely solely on simple limit plates or conveyor wheels to constrain the paper, failing to actively adjust the paper's position before stacking. When the paper shifts due to factors such as cutting errors, conveyor speed fluctuations, or mechanism vibrations, it cannot be corrected by the mechanism's own structure, resulting in uneven edges of the stacked paper, or even tilting or collapsing.

[0004] Limited conveying path and lack of flexibility: Existing stacking mechanisms are mostly single-channel conveyors, which are difficult to adapt to paper handling of different specifications and conveying requirements. For example, when paper needs to be stacked in layers, it is impossible to switch conveying paths to achieve paper classification and conveying, resulting in low subsequent stacking efficiency.

[0005] Therefore, a paper conveying and stacking mechanism is provided to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a paper conveying and stacking mechanism to address the shortcomings of existing technologies, thereby solving the technical problems of existing stacking mechanisms lacking automatic alignment functions and having a single conveying path during the paper conveying and stacking process.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A paper conveying and stacking mechanism includes a support frame, the support frame is equipped with a paper feeding table for conveying paper and a first limiting plate placed above the paper feeding table, and a paper feeding channel is formed between the paper feeding table and the first limiting plate.

[0009] The support frame is provided with a first conveyor and a second conveyor. Both the first conveyor and the second conveyor are connected to the outlet of the paper feeding channel. An adjustment component is installed at the outlet of the paper feeding channel to control the connection between the first conveyor and the paper feeding channel or between the second conveyor and the paper feeding channel.

[0010] It also includes a first alignment conveying unit and a second alignment conveying unit for conveying paper and adjusting and aligning the paper during the conveying process. The beginning end of the first alignment conveying unit is connected to the end end of the first conveying table, and the beginning end of the second alignment conveying unit is connected to the end end of the second conveying table.

[0011] It also includes a fixed frame, which is equipped with a first stacking component that connects to the end of the first alignment conveyor and a second stacking component that connects to the end of the second alignment conveyor. Both the first and second stacking components are used to stack the paper that has been aligned.

[0012] The beneficial effects of this invention are as follows: In use, paper is fed into the paper feeding channel. During feeding, the adjusting component controls the connection between the initial end of the first conveyor and the outlet of the paper feeding channel, or between the initial end of the second conveyor and the outlet of the paper feeding channel. Specifically: when the first conveyor is connected to the paper feeding channel, the second conveyor is disconnected, and the first conveyor feeds the paper to the top surface of the first conveyor, which continues to feed the paper. After operating the adjusting component, the second conveyor is connected to the paper feeding channel, while the first conveyor is disconnected, and the second conveyor feeds the paper to the top surface of the second conveyor, which continues to feed the paper. With the cooperation of the first conveyor, the second conveyor, and the adjusting component, layered feeding of the paper is achieved, enabling not only classified stacking but also improved efficiency in subsequent palletizing and stacking.

[0013] In addition, after the paper is conveyed to the first alignment conveyor and the second alignment conveyor respectively, the first alignment conveyor and the second alignment conveyor also convey the paper, and adjust the position of the paper during the conveying process to align the paper in a straight line array. After alignment, the paper is then conveyed to the first stacking component and the second stacking component respectively. Both components operate simultaneously to stack the adjusted paper. Adjusting and aligning the paper before stacking prevents the stacked paper from tilting or collapsing, thus improving the stacking effect of this stacking mechanism. Attached Figure Description

[0033] The following is a detailed description of a paper conveying and stacking mechanism according to the present invention, with reference to the accompanying drawings.

[0034] like Figure 1-4As shown, an embodiment of the paper conveying and stacking mechanism of this utility model includes a support frame 601 and a support frame 602 mounted on the support frame 601. The support frame 602 is equipped with a paper feeding table 603 for conveying paper, and a plurality of conveying modules are arranged on the top surface of the paper feeding table 603. A first limiting plate 606 is arranged above the paper feeding table 603 for limiting the paper during the conveying process, and a paper feeding channel 607 is formed between the top surface of the paper feeding table 603 and the bottom surface of the first limiting plate 606. The inlet of the paper feeding channel 607 is connected to the paper outlet of a cutting mechanism (not shown in the figure). After the cutting mechanism cuts the paper strip into sheets, the sheets are fed into the paper feeding channel 607, and the plurality of conveying modules on the paper feeding table 603 are controlled to rotate to achieve continuous conveying of paper. In addition, during the conveying process, the first limiting plate 606 limits the paper to prevent the paper from deviating from or leaving the conveying track.

[0035] The conveying module includes a second rotating rod 604 arranged laterally with its axis perpendicular to the paper conveying direction. The second rotating rod 604 is rotatably mounted on the paper feeding table 603 and is equipped with several conveying wheels 605. After the paper is fed into the paper feeding channel 607, the paper is placed on the several conveying wheels 605. By driving the second rotating rod 604 to rotate, the several conveying wheels 605 can be rotated synchronously, thus conveying the paper.

[0036] Furthermore, the support frame 602 is provided with a first conveyor 608 connected to the outlet of the paper feeding channel 607, and a second conveyor 6010 connected to the outlet of the paper feeding channel 607. Both the first conveyor 608 and the second conveyor 6010 are used to convey paper, and the conveying direction of the first conveyor 608 can be consistent with the conveying direction of the paper feeding table 603. The conveying direction of the second conveyor 6010 is arranged obliquely upward relative to the conveying direction of the paper feeding table 603. The top surfaces of the first conveyor 608 and the second conveyor 6010 are provided with the conveying modules as described above. An adjustment component is installed at the outlet of the paper feeding channel 607 to control the selective connection between the first conveyor 608 and the paper feeding channel 607 or the second conveyor 6010 and the paper feeding channel 607.

[0037] By setting an adjustment component, the connection between the initial end of the first conveyor 608 and the outlet of the paper feeding channel 607, or the connection between the initial end of the second conveyor 6010 and the outlet of the paper feeding channel 607, can be controlled. Specifically: when the first conveyor 608 is connected to the paper feeding channel 607, the second conveyor 6010 is disconnected from the paper feeding channel 607, and the paper feeding platform 603 conveys the paper to the top surface of the first conveyor 608, and then the paper continues to be conveyed through the conveying module set on the top surface of the first conveyor 608; after running the adjustment component, the connection between the second conveyor 6010 and the paper feeding channel 607 can be controlled, while the first conveyor 608 is disconnected from the paper feeding channel 607, and the paper feeding platform 603 conveys the paper to the top surface of the second conveyor 6010, and then the paper continues to be conveyed through the conveying module set on the top surface of the second conveyor 6010. With the cooperation of the first conveyor 608, the second conveyor 6010, and the adjusting components, the paper is conveyed in layers to different positions for stacking. This not only enables classified stacking but also improves the efficiency of subsequent stacking.

[0038] A second limiting plate 609 is provided above the first conveyor 608, and a third limiting plate 6011 is provided above the second conveyor 6010. The first limiting plate 606, the second limiting plate 609, and the third limiting plate 6011 have the same function: to limit the paper and prevent it from deviating from or leaving the conveying track during the conveying process.

[0039] In this embodiment, the support frame 601 is further equipped with a first alignment conveying section 6014 and a second alignment conveying section 6015 for conveying paper and adjusting the paper alignment during the conveying process. The initial end of the first alignment conveying section 6014 is connected to the end of the first conveying table 608, and the initial end of the second alignment conveying section 6015 is connected to the end of the second conveying table 6010. After the paper is conveyed to the first conveying table 608 and the second conveying table 6010 respectively, the first conveying table 608 and the second conveying table 6010 continue to convey the paper to the first alignment conveying section 6014 and the second alignment conveying section 6015 respectively. The first alignment conveying section 6014 and the second alignment conveying section 6015 also convey the paper, and adjust the position of the paper during the conveying process to align the paper in a straight line array, so that the paper stacks are neat after subsequent stacking.

[0040] Furthermore, the support frame 601 is provided with a fixed frame 701, which is equipped with a first stacking component 702 for connecting to the end of the first alignment conveyor 6014, and a second stacking component 703 for connecting to the end of the second alignment conveyor 6015. The first stacking component 702 and the second stacking component 703 are arranged vertically and are both used to stack the adjusted paper. The first alignment conveyor 6014 and the second alignment conveyor 6015 adjust and align the paper on different conveying paths, and then convey it to the first stacking component 702 and the second stacking component 703 respectively. Both operate simultaneously to stack the conveyed paper. The specific stacking method is described below.

[0041] The first alignment conveying unit 6014 and the second alignment conveying unit 6015 have the same structure and operate in the same way, such as Figure 5-6 As shown, the first alignment conveying unit 6014 includes a support base 60141 and a support platform 60142 mounted on the support base 60141. The support platform 60142 is used to support the paper during the adjustment process. The support base 60141 has a first pulley 60143 rotatably mounted at its initial end and a second pulley 60144 rotatably mounted at its end. The first pulley 60143 is located near the middle of the initial end of the support base 60141, and the initial end of the support base 60141 is connected to the end of the first conveyor table 608. The second pulley 60144 is located near the edge of the end of the support base 60141, so that the arrangement of the first pulley 60143 and the second pulley 60144 is inclined based on the paper conveying direction. A conveyor belt 60145 for inclined conveying of paper is wound around the first pulley 60143 and the second pulley 60144, and the upper half of the conveyor belt 60145 is inclinedly placed on the top surface of the support platform 60142. After the first conveyor 608 conveys the paper to the support platform 60142, the bottom surface of the paper contacts the upper half of the conveyor belt 60145. After controlling the conveyor belt 60145 to move, the paper can be conveyed along the inclined direction.

[0042] A positioning rod 60146 is provided on the edge of the support base 60141 near the second pulley 60144 for positioning and aligning the paper during the adjustment process. The length direction of the positioning rod 60146 is parallel to the paper conveying direction of the corresponding conveying module. During the process of conveying the paper along the inclined direction by the conveyor belt 60145, each piece of paper contacts the positioning rod 60146 one by one. The positioning rod 60146 blocks the side of the paper to achieve uniform positioning, thereby adjusting the position of the paper and aligning it along the length direction of the positioning rod 60146, arranging the paper in a linear array.

[0043] In addition, a protective plate 601413 is provided above the positioning rod 60146 to protect the paper during the adjustment process; the protective plate 601413 prevents the paper from tilting during the adjustment and alignment process, or from deforming after the paper comes into contact with the positioning rod 60146 during the conveying process.

[0044] A guide rod 60147 with its axis arranged laterally and perpendicular to the paper conveying direction is provided on the support frame 601. The support seat 60141 is laterally slidably disposed on the guide rod 60147. By controlling the support seat 60141 to slide laterally on the guide rod 60147, the positions of the conveyor belt 60145 and the positioning rod 60146 are adjusted to accommodate paper of different sizes.

[0045] To drive the conveyor belt 60145, a first splined shaft 60148 with its axis parallel to the axis of the guide rod 60147 is also provided on the support frame 601. A first transmission gear 60149 and a second transmission gear 601410 are rotatably provided on the support base 60141. The second transmission gear 601410 is coaxially arranged with and fixed to the second pulley 60144 (or the first pulley 60143). The first transmission gear 60149 is coaxially arranged with and slidably arranged with the first splined shaft 60148. A transmission toothed belt 601411 is wound around the first transmission gear 60149 and the second transmission gear 601410. When the first splined shaft 60148 rotates, it drives the first transmission gear 60149 to rotate. Furthermore, under the transmission action of the transmission belt 601411 and the second transmission gear 601410, the second pulley 60144 (or the first pulley 60143) is driven to rotate, thereby driving the conveyor belt 60145. Additionally, when the control support 60141 slides laterally on the guide rod 60147, the first transmission gear 60149 can slide on the first splined shaft 60148. After adjusting the position of the first transmission gear 60149, the first splined shaft 60148 can still drive the first transmission gear 60149 to rotate.

[0046] At the end of the support base 60141, a guide lip plate 601412 is provided, which connects to the first stacking component 702 (the first alignment conveying part 6014 connects to the first stacking component 702). The guide lip plate 601412 is used to guide the adjusted paper to the first stacking component 702 for stacking. The protective plate 601413 is equipped with a fixing frame 601414, which has several limiting rods 601415 for preventing the paper from falling off the support platform 60142. The limiting rods 601415 are used to limit the paper placed on the support platform 60142, so that the paper can be accurately conveyed between the protective plate 601413 and the support platform 60142 and contact the positioning rod 60146 during the inclined conveying process.

[0047] like Figure 7 As shown, the adjusting component includes a second rotating shaft 6012 rotatably mounted on the support frame 601 and whose axis is parallel to the axis of the second rotating rod 604. The second rotating shaft 6012 is provided with a guide plate 6013 for switching the paper feeding direction. The initial state of the guide plate 6013 is that its top surface is flat. The end of the guide plate 6013 near the paper feeding channel 607 is not in contact with the top surface of the first conveyor table 608. At this time, the second conveyor table 6010 is disconnected from the paper feeding channel 607, and the paper feeding table 603 can transport the paper to the top surface of the first conveyor table 608. When it is necessary to switch the conveying direction, the second rotating shaft 6012 is controlled to rotate, so as to drive the guide plate 6013 to rotate together. When the end of the guide plate 6013 near the paper feeding channel 607 rotates to contact the top surface of the first conveyor table 608, the top surface of the guide plate 6013 is inclined. Under the bridging effect of the guide plate 6013, the second conveyor table 6010 is connected to the paper feeding channel 607, while the first conveyor table 608 is disconnected from the paper feeding channel 607, thus realizing the switching of the paper conveying direction.

[0048] In this embodiment, the top surface of the paper feeding table 603 is formed with a second waste outlet 6016 for discharging waste paper. A third rotating shaft 6017, with its axis parallel to the axis of the second rotating rod 604, is rotatably disposed within the second waste outlet 6016. The third rotating shaft 6017 is equipped with a second baffle plate 6018 for blocking and guiding waste paper into the second waste outlet 6016. When no waste paper is detected, the surface of the second baffle plate 6018 is flush with the top surface of the paper feeding table 603. Simultaneously, the second baffle plate 6018 blocks the second waste outlet 6016. During the paper conveying process by the conveyor wheel 605, the paper continuously passes over the surface of the second baffle plate 6018 without obstructing the paper during conveying. When damaged or non-compliant paper is detected, the third rotating shaft 6017 is controlled to rotate counterclockwise (rotation direction is...). Figure 2Based on the reference, the second baffle plate 6018 is tilted up at the end near the feed inlet of the paper feeding channel 607, thereby opening the second waste outlet 6016. The second baffle plate 6018 blocks the damaged or non-compliant paper during the conveying process and guides it to the second waste outlet 6016. The damaged or non-compliant paper is discharged to the bottom of the paper feeding table 603 (i.e., discharged from the paper feeding channel 607) for collection through the second waste outlet 6016. When qualified paper is detected, the third rotating shaft 6017 is controlled to rotate to drive the second baffle plate 6018 to reset.

[0049] like Figure 8 As shown, the first stacking component 702 includes a clamping and conveying section 7021 for clamping and conveying the aligned paper and a stacking conveyor 7023 for supporting the paper stack. It also includes a paper stacking section 7022 for transporting the paper on the clamping and conveying section 7021 to the stacking conveyor 7023 for stacking, and a guide and limiting section 7024 for guiding and limiting the paper during the stacking process.

[0050] The clamping conveyor 7021 and the stacking conveyor 7023 are arranged vertically, and the paper stacking part 7022 is placed between the clamping conveyor 7021 and the stacking conveyor 7023. After the first alignment conveyor 6014 conveys the aligned paper to the clamping conveyor 7021, it is received by the clamping conveyor 7021. The clamping conveyor 7021 clamps and conveys the paper to the paper stacking part 7022. Then the paper stacking part 7022 stacks the paper one by one onto the stacking conveyor 7023 for stacking. During the stacking process, the stacking conveyor 7023 moves downward intermittently with the thickness of the paper stack, and the guide and limit part 7024 guides and limits the paper, so that the paper stack on the stacking conveyor 7023 remains neat and prevents the sides of the paper stack from deviating and collapsing.

[0051] like Figure 9 As shown, the paper stacking section 7022 includes a rotating shaft 70221 with its axis arranged laterally and its length direction perpendicular to the paper conveying direction. The rotating shaft 70221 is rotatably mounted on the fixed frame 701, and the rotating shaft 70221 is equipped with several paper conveying wheels 70222 for conveying papers to the stacking conveyor table 7023 for stacking. Each paper conveying wheel 70222 has several placement slots 70223 formed on it for placing papers. The placement slots 70223 are arranged in an equidistant rotating array around the axis of the rotating shaft 70221. The placement slots 70223 are arc-shaped, and one paper can be placed in one placement slot 70223. The rotating shaft 70221 drives the several paper conveying wheels 70222 to rotate counterclockwise at a uniform speed (rotation direction is...). Figure 9(Based on this), when the opening of one of the placement slots 70223 aligns with the paper output end of the clamping and conveying unit 7021, the clamping and conveying unit 7021 conveys the paper into the placement slot 70223. Then, the paper conveying roller 70222 drives the paper to rotate around the axis of the rotating shaft 70221 until the opening of the next placement slot 70223 aligns with the paper output end of the clamping and conveying unit 7021, at which point the next sheet of paper is conveyed into that placement slot 70223. This operation allows for continuous paper transport, as the paper is... The paper is transported from top to bottom, and the placement slot 70223 is arc-shaped. So when the paper conveying roller 70222 transports the paper to contact the top of the stacking conveyor 7023, the paper conveying roller 70222 continues to rotate. Under the action of the paper's own weight, the paper automatically detaches from the placement slot 70223 and is stacked one by one on the stacking conveyor 7023 for stacking. In addition, during the stacking process, the stacking conveyor 7023 moves downward intermittently according to the thickness of the paper stack, adapting to the change in the thickness of the paper stack.

[0052] like Figure 10 As shown, the clamping and conveying unit 7021 includes a first mounting frame 70211 mounted on a fixed frame 701. The first mounting frame 70211 is provided with a lower clamping part 70212 and an upper clamping part 70213 arranged vertically. Paper is placed between the lower clamping part 70212 and the upper clamping part 70213 to clamp it. After clamping, it is conveyed to the placement groove 70223 on the paper conveying roller 70222.

[0053] The lower clamping part 70212 and the upper clamping part 70213 have the same structure and are arranged symmetrically. The upper clamping part 70213 includes a first support rod 702131 whose axis is parallel to the axis of the rotating shaft 70221. Several first movable seats 702132 are laterally slidably provided on the first support rod 702131. Each first movable seat 702132 is rotatably provided with a third pulley 702133 and a fourth pulley 702134. The third pulley 702133 and the fourth pulley 702134 are respectively placed at the beginning and end of the first movable seat 702132 and arranged along the paper feeding direction. A paper feeding belt 702135 is wound around the third pulley 702133 and the fourth pulley 702134. The lower half of the paper feeding belt 702135 is in contact with the lower clamping part 70212.

[0054] When the paper is placed between the lower clamping part 70212 and the upper clamping part 70213, it is clamped by the paper feeding belts 702135 arranged vertically, and then the third pulley 702133 or the fourth pulley 702134 is driven to rotate. The paper feeding belts 702135 can transport the paper by moving.

[0055] In order to drive the paper feeding belt 702135 to move, the upper clamping part 70213 also includes a second spline shaft 702136 whose axis is parallel to the axis of the first support rod 702131. The second spline shaft 702136 is rotatably mounted on the first mounting frame 70211. The second spline shaft 702136 and the third pulleys 702133 on each of the first movable seats 702132 are coaxially arranged, and the second spline shaft 702136 and the third pulleys 702133 are slidably arranged. When the second spline shaft 702136 is driven to rotate, the third pulleys 702133 on each of the first movable seats 702132 will rotate simultaneously. In addition, when the first movable seats 702132 are controlled to slide laterally on the first support rod 702131 to adjust the spacing of each of the first movable seats 702132 to accommodate different sizes of paper, the third pulleys 702133 slide on the second spline shaft 702136 during the lateral sliding process.

[0056] like Figure 11 As shown, the stacking conveyor 7023 includes a second mounting frame 70231 that is movably mounted on a fixed frame 701. The second mounting frame 70231 is provided with a second support rod 70232 whose axis is parallel to the axis of the rotating shaft 70221. Several second movable seats 70233 for supporting the paper stack are slidably provided on the second support rod 70232. Each second movable seat 70233 is rotatably provided with a fifth pulley 70234 and a sixth pulley 70235. The fifth pulley 70234 and the sixth pulley 70235 are respectively located at the beginning and end of the second movable seat 70233 and arranged along the paper conveying direction. A support belt 70236 is wound around the fifth pulley 70234 and the sixth pulley 70235. The upper half of the support belt 70236 is placed above the second movable seat 70233 for conveying the stacked paper stack. The paper conveyor rollers 70222 transport the paper to the second movable seats 70233 for stacking, with the bottom of the paper stack contacting the upper half of the support belt 70236. After the paper is stacked, the fifth pulley 70234 or the sixth pulley 70235 is driven to rotate, and the support belt 70236 transports the paper stack for subsequent stacking. Furthermore, by adjusting the spacing between the second movable seats 70233, paper stacks of different sizes can be supported.

[0057] The second mounting frame 70231 is also rotatably provided with a third splined shaft 70237, whose axis is parallel to the axis of the second support rod 70232. The third splined shaft 70237 and the fifth pulleys 70234 on each of the second movable seats 70233 are arranged coaxially, and the third splined shaft 70237 and the fifth pulleys 70234 are slidably disposed. During the lateral sliding process, the fifth pulleys 70234 slide on the third splined shaft 70237, and the third splined shaft 70237 can drive the fifth pulleys 70234 in different positions.

[0058] like Figure 12 As shown, the guide limiting part 7024 includes a mounting frame 70241 mounted on a fixed frame 701. The mounting frame 70241 is provided with a left sliding seat 70242 and a right sliding seat 70243 that can slide towards or away from each other. The sliding direction of the left sliding seat 70242 and the right sliding seat 70243 is parallel to the axis of the rotation shaft 70221. The left sliding seat 70242 and the right sliding seat 70243 are respectively equipped with a left guide plate 70244 and a right guide plate 70245 for guiding the paper during the stacking process, and a stacking station 70246 is located between the left guide plate 70244 and the right guide plate 70245. The paper conveyor roller 70222 rotates, transporting the paper to the stacking station 70246 between the left guide plate 70244 and the right guide plate 70245, where it is stacked one by one onto the stacking conveyor 7023. During the stacking process, the left guide plate 70244 and the right guide plate 70245 guide the paper to keep the left and right sides of the paper stack neat. In addition, by controlling the left sliding seat 70242 and the right sliding seat 70243 to move closer or further apart, the spacing between the left guide plate 70244 and the right guide plate 70245 can be controlled to accommodate paper of different sizes.

[0059] In this embodiment, the front and rear sides of the stacking station 70246 are respectively provided with a paper stop bar 70247 and a pusher plate 702413 for limiting the paper during the stacking process. A pair of third rotating rods 70248 are provided and fixedly mounted on the left sliding seat 70242 and the right sliding seat 70243, respectively. The pusher plate 702413 is movably mounted on the mounting frame 70241, and reciprocates in the direction of approaching or moving away from the stacking station 70246 to push the paper stack neatly. During the stacking process at the stacking station 70246, the pusher plate 702413 reciprocates in the direction of approaching or moving away from the stacking station 70246, pushing the paper stack into contact with the pusher plate 702413, thereby aligning the front and rear sides of the paper stack and making the paper stack neat.

[0060] During the guiding process via the left guide plate 70244 and the right guide plate 70245, to prevent paper jams, a third rotating rod 70248 and a fourth rotating rod 70249 are rotatably provided on the left sliding seat 70242 and the right sliding seat 70243, arranged vertically and with their axes parallel to the paper conveying direction. Both the third rotating rod 70248 and the fourth rotating rod 70249 are equipped with a seventh pulley 702410, and a paper guide belt 702411 is wound around the vertically arranged seventh pulley 702410. Both the left guide plate 70244 and the right guide plate 70245 have openings 702412 formed on them, which are used to allow a section of the side of the paper guide belt 702411 to pass through near the stacking station 70246. After the paper guide belt 702411 on the left sliding seat 70242 passes through the opening 702412, a section of its side near the stacking station 70246 is flush with or protrudes from the inner wall of the left guide plate 70244. Similarly, after the paper guide belt 702411 on the right sliding seat 70243 passes through the opening 702412, a section of its side near the stacking station 70246 is flush with or protrudes from the inner wall of the right guide plate 70245. During the process of guiding the paper through the left guide plate 70244 and the right guide plate 70245, the left and right sides of the paper contact the surfaces of different paper guide belts 702411. After driving the left and right paper guide belts 702411 towards the stacking station 70246, a downward force is applied to the paper, improving the guiding effect and preventing paper jams.

[0061] In order for the pusher plate 702413 to reciprocate in the direction of moving closer to or away from the stacking station 70246, the mounting frame 70241 is fixedly provided with a guide seat 702414. The guide seat 702414 is provided with a slider 702415 that can slide in the direction of moving closer to or away from the stacking station 70246. The pusher plate 702413 is fixedly provided with the slider 702415. The slider 702415 is formed with a receiving groove 702416. The mounting frame 70241 is rotatably provided with a fifth rotating rod 702417 whose axis is parallel to the sliding direction of the left sliding seat 70242 (or the right sliding seat 70243). The fifth rotating rod 702417 passes through the receiving groove 702416. The fifth rotating rod 702417 is provided with a cam 702418 placed in the receiving groove 702416 and used to push the slider 702415 to slide. When the fifth rotating rod 702417 drives the cam 702418 to rotate, the cam 702418 swings around the axis of the fifth rotating rod 702417 in the receiving groove 702416. The swing end of the cam 702418 contacts the inner wall of the receiving groove 702416, which can apply different directional thrusts to the slider 702415 (towards or away from the stacking station 70246), thereby driving the slider 702415 to reciprocate on the guide seat 702414 in the direction of approaching or away from the stacking station 70246. At the same time, it also moves the pusher plate 702413 to push the sides of the paper stack together.

[0062] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
