Description

Technical Field

[0001] The present invention relates to the technical field of paper processing, and particularly to a paper production line integrating unwinding, folding, cutting, and stacking. Background Art

[0002] In the technical field of paper processing, the automation degree and processing accuracy of a paper production line directly affect product quality and production efficiency. Existing paper production lines usually need to complete multiple processes such as unwinding, folding, cutting, and stacking. Among them, the folding process is a key link, and its accuracy and adaptability are crucial for subsequent cutting and finished product quality. There are generally two major technical bottlenecks in the traditional paper production line during the paper folding process:

[0003] First, the folding accuracy is insufficient. Since the paper tape released from the reel paper is prone to deviation during the conveying process due to factors such as uneven tension and equipment vibration, resulting in position deviation of the left and right sides during folding, causing problems such as crooked folding and wrinkles; in addition, there is a lack of pre-positioning treatment for the paper tape during the folding process, and the folding action only relies on mechanical contact to forcibly bend, further exacerbating the folding error. Especially during high-speed production, the accuracy problem is more significant.

[0004] Second, the adaptability to paper tapes of different sizes is poor. The folding positions of existing paper folding mechanisms are mostly fixed structures and are difficult to flexibly adjust according to the width of the paper tape; when producing papers of different specifications (such as A4 paper, wrapping paper, etc.), it is necessary to stop the machine to replace the mold or re-adjust the equipment, which is time-consuming and laborious, and severely restricts the diversified production capacity of the production line. At the same time, for wide-width paper tapes, the traditional single-side folding method has low efficiency and cannot form paper tapes of multiple target sizes through one-time folding, resulting in the need for multiple cuts in the cutting process, which not only reduces production efficiency but also increases the cumulative risk of cutting errors.

[0005] In addition, when the paper tape is folded, it is prone to rebound due to the elastic deformation of the paper fibers, resulting in uneven folding lines and angle deviation, further affecting the subsequent cutting accuracy. Therefore, a paper production line integrating unwinding, folding, cutting, and stacking is provided to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a paper production line integrating unwinding, folding, cutting, and stacking for the deficiencies of the existing technology, so as to solve the technical problems of low folding accuracy of the existing paper production line and the inability to fold paper tapes of different sizes.

[0007] To achieve the above purpose, the technical solution of the present invention is as follows:

[0008] A paper production line integrating unwinding, folding, cutting, and stacking, comprising a paper feeding mechanism for controlling the rotation of a reel of paper to continuously release a paper tape, and a deviation rectifying mechanism for rectifying and aligning the released paper tape. It also includes a paper folding mechanism for folding the rectified and aligned paper tape, a cutting mechanism for cutting the folded paper tape into sheets, a paper conveying mechanism for conveying the sheets, and a stacking mechanism for stacking the conveyed sheets; the paper feeding mechanism, the deviation rectifying mechanism, the paper folding mechanism, the cutting mechanism, the paper conveying mechanism, and the stacking mechanism are connected in sequence according to the production process.

[0009] The paper folding mechanism includes a frame. The frame is equipped with a first indentation mechanism for conveying the unfolded paper tape and indentating its surface, and is also equipped with a right folding edge assembly and a left folding edge assembly arranged in sequence along the paper tape conveying direction. The left folding edge assembly and the right folding edge assembly are movably arranged on the frame, and the moving direction is the same as the width direction of the paper tape; the left folding edge assembly and the right folding edge assembly are respectively used for folding the left and right length edges of the unfolded paper tape, and the deviation rectifying mechanism is connected to the first indentation mechanism to rectify the paper tape during the conveying process.

[0010] The beneficial effects of the present invention: During production, after loading the reel of paper on the paper feeding mechanism, it is driven to rotate, thereby continuously releasing the paper tape. Subsequently, the paper tape passes through the deviation rectifying mechanism to rectify and align the paper tape, so that it is always conveyed in one direction and is conveyed to the subsequent cutting mechanism for cutting. Since the width of the paper tape is relatively long, before cutting the paper tape, it is necessary to first fold the width of the paper tape into a specified size, and then cut it through the cutting mechanism, so that multiple target-sized sheets can be obtained by single cutting, improving the cutting accuracy and efficiency. After the cutting mechanism cuts the folded paper tape into sheets, it is conveyed onto the paper conveying mechanism and then continues to be conveyed through the paper conveying mechanism and is stacked into a paper stack on the stacking mechanism, completing the production of the sheets.

[0011] Among them, the first indentation mechanism drives the unfolded paper tape to be continuously conveyed. After being conveyed onto the right folding edge assembly, since the right length edge of the paper tape reaching the right folding edge assembly is in a folded state, during the continuous conveying of the paper tape, it can gradually transition from the unfolded state to the state where the right length edge is in a folded state; the right length edge of the paper tape after folding is conveyed onto the left folding edge assembly. Since the left length edge of the paper tape reaching the left folding edge assembly is in a folded state and the right length edge of the paper tape located on the right folding edge assembly is in a folded state, during the continuous conveying of the paper tape, the paper tape with the right length edge in a folded state can be gradually transitioned to the paper tape with both the left and right length edges in a folded state, realizing automatic and continuous paper folding processing and improving the folding efficiency.

[0012] Secondly, during the continuous transportation of the paper tape in the unfolded state, the first indentation mechanism performs indentation processing on the paper surface, thereby pressing out dotted or linear traces on the surface of the paper tape, which facilitates avoiding the situation of the paper tape being folded crooked during subsequent paper folding, further improving the folding efficiency and accuracy. Moreover, by controlling the positions of the left folding edge component and the right folding edge component, the folding positions of the left and right length edges of the paper tape can be adjusted, so as to fold the paper tape into different states; according to paper tapes of different widths, the folding positions can be adjusted to achieve folding processing of paper tapes of different widths, significantly enhancing the product adaptability of this production line and meeting the diverse production requirements.

Detailed implementation mode

[0056] The following describes in detail a paper production line integrating uncoiling, folding, cutting, and stacking of the present invention with reference to the accompanying drawings.

[0057] As Figure 1As shown in the figure, an embodiment of a paper production line integrating unwinding, folding, cutting, and stacking of the present invention includes a paper feeding mechanism 1 for controlling the rotation of the reel paper 100 to continuously discharge the paper tape 200, and a deviation rectifying mechanism 2 for rectifying the discharged paper tape 200. The deviation rectifying mechanism 2 is connected to the paper outlet end of the paper feeding mechanism 1. After the reel paper 100 is installed on the paper feeding mechanism 1, it is driven to rotate, thereby continuously discharging the paper tape 200. Subsequently, the paper tape 200 passes through the deviation rectifying mechanism 2, and the paper tape 200 is rectified to always be conveyed in one direction. Among them, the paper production line further includes a paper folding mechanism 3 for folding the rectified paper tape 200 and a cutting mechanism 5 for cutting the folded paper tape 200 into paper sheets. Since the width of the paper tape 200 is relatively long, before cutting the paper tape 200, the width of the paper tape 200 is first folded into a specified size (such as A4 paper, wrapping paper, etc.), and then cut by the cutting mechanism 5, so that multiple target-sized paper sheets can be obtained by single cutting, improving the cutting accuracy and efficiency. In addition, the paper production line further includes a paper conveying mechanism 6 for conveying the paper sheets and a stacking mechanism 7 for stacking the conveyed paper sheets. After the cutting mechanism 5 cuts the folded paper tape 200 into paper sheets, it is conveyed onto the paper conveying mechanism 6, and then continues to be conveyed through the paper conveying mechanism 6. Moreover, the paper conveying mechanism 6 has the function of adjusting and aligning the paper sheets, adjusting the paper sheets to an aligned state arranged in a straight line array. After alignment, it is conveyed onto the stacking mechanism 7 and stacked into a paper stack to complete the production of the paper sheets. The paper feeding mechanism 1, the deviation rectifying mechanism 2, the paper folding mechanism 3, the cutting mechanism 5, the paper conveying mechanism 6, and the stacking mechanism 7 are connected in sequence according to the production process.

[0058] As Figures 2 - 4 shown, the paper feeding mechanism 1 includes a first support frame 101 and a U-shaped frame 103 installed on the first support frame 101. First support shafts 102 with a horizontal axis are provided on the vertically extending columns on both sides of the U-shaped frame 103, and the first support shafts 102 are rotatably arranged with the first support frame 101. Under the action of the first support shafts 102, the U-shaped frame 103 can rotate around the horizontally arranged axis on the first support frame 101. Or the first support shafts 102 are fixedly arranged on the first support frame 101, and the first support shafts 102 are rotatably arranged with the U-shaped frame 103, which can also make the U-shaped frame 103 rotate on the first support frame 101. Among them, the paper feeding mechanism 1 further includes an air shaft 105 for supporting the reel paper 100. The non-inflated air shaft 105 is horizontally inserted into the central hole of the reel paper 100, and then the air shaft 105 is inflated to tightly press against the inner wall of the central hole, so as to fix the reel paper 100 on the air shaft 105. First placement grooves 104 are provided at the ends of the vertically extending columns on both sides of the U-shaped frame 103 (such as Figure 5As shown, both ends of the air shaft 105 are respectively placed in different first placement grooves 104. Since the reel paper 100 is relatively heavy, the U-shaped frame 103 is rotatably arranged on the first support frame 101 to facilitate lifting the reel paper 100 to a specified position for the paper feeding process. Specifically: first, insert the air shaft 105 into the central hole of the reel paper 100, and then place the reel paper 100 with the air shaft 105 between the upright columns vertically extending on both sides of the U-shaped frame 103. At this time, the reel paper 100 with the air shaft 105 is placed on the ground, and the ends of the upright columns vertically extending on both sides of the U-shaped frame 103 are at a low position (i.e., below the air shaft 105). Subsequently, control the U-shaped frame 103 to rotate counterclockwise around the horizontally arranged axis (the rotation direction is based on Figure 3 as a reference). The ends of the upright columns vertically extending on both sides of the U-shaped frame 103 swing around the axis of the first support shaft 102. During the swinging process, both ends of the air shaft 105 are respectively automatically placed in different first placement grooves 104. The U-shaped frame 103 continues to rotate counterclockwise, thereby lifting the air shaft 105 to lift the reel paper 100 to a specified position (such as Figure 2 shown), facilitating the feeding process of the reel paper 100.

[0059] To control the rotation of the reel paper 100 for paper feeding, a driven gear 106 is provided at one end of the air shaft 105, and driving gears 107 are provided on the upright columns vertically extending on both sides of the U-shaped frame 103. When both ends of the air shaft 105 are respectively placed in different first placement grooves 104, the driven gear 106 meshes with the driving gear 107, and the end of the air shaft 105 can rotate in the first placement groove 104. After controlling the rotation of the U-shaped frame 103 to lift the reel paper 100 to a specified position, then control the rotation of the driving gear 107. Under the transmission action of the driven gear 106, the rotation of the reel paper 100 can be controlled to perform the paper feeding process and continuously discharge the paper tape 200. The paper feeding mechanism 1 further includes a driving assembly 108 for controlling the rotation of the driving gear 107. Operating the driving assembly 108, under the transmission action of the driving gear 107 and the driven gear 106, the rotation of the reel paper 100 is controlled.

[0060] In this embodiment, in order to control the rotation of the U-shaped frame 103, a first rotating member 109 is rotatably provided at the end of the U-shaped frame 103 away from the first placement groove 104, and the axis of rotation of the first rotating member 109 is parallel to the axis of the first support shaft 102. The first support frame 101 is also movably provided with a swinging member 1010 disposed below the first rotating member 109. The axis of swing of the swinging member 1010 is parallel to the axis of rotation of the first rotating member 109. The swinging member 1010 is provided with a reduction gearbox 10101 and a first servo motor 10102, and the input shaft of the reduction gearbox 10101 is in transmission connection with the output shaft of the first servo motor 10102. A trapezoidal screw 1011 with a vertically arranged axis is provided on the output shaft of the reduction gearbox 10101. The rotating member 109 is provided with a trapezoidal nut 1012 for threaded connection with the trapezoidal screw 1011. Before controlling the U-shaped frame 103 to rotate counterclockwise to lift the web 100, the end of the U-shaped frame 103 away from the placement groove 104 is in a raised state. The first servo motor 10102 is operated, and after deceleration by the reduction gearbox 10101, the trapezoidal screw 1011 is driven to rotate, thereby controlling the trapezoidal nut 1012 to move downward along its axis on the trapezoidal screw 1011. At the same time, a downward traction force is applied to the rotating member 109 to make it move together. Since the rotating member 109 can only move (the movement trajectory of the rotating member 109 is an arc) around the axis of the support shaft 102 and rotates on the U-shaped frame 103 itself, the swinging member 1010 will swing clockwise, and the trapezoidal screw 1011 and the first servo motor 10102 will also swing clockwise to always adapt to the position of the rotating member 109. During the process of applying a downward traction force to the rotating member 109, a downward pulling force is applied to the end of the U-shaped frame 103 away from the placement groove 104, and the U-shaped frame 103 moves counterclockwise, causing the ends of the vertical columns extending vertically on both sides of the U-shaped frame 103 to be lifted, realizing the lifting of the web 100. In addition, when the web 100 needs to be replaced, the trapezoidal screw 1011 is controlled to rotate in the reverse direction. The ends of the vertical columns extending vertically on both sides of the U-shaped frame 103 will slowly descend, facilitating the removal of the air shaft 105 and the replacement of the web 100, and facilitating the loading of the web 100.

[0061] After controlling the rotation of the web reel 100 to continuously unwind the web tape 200, in order to facilitate the smooth conveyance of the web tape 200 to the next mechanism, the first support frame 101 is provided with a pair of sixth guide rollers 1013 arranged vertically and used for horizontally guiding the unwound web tape 200, and also provided with an overhead roller 1015 for continuously conveying the web tape 200, and a third pressure roller 1016 for pressing the web tape 200 against the overhead roller 1015. After the web reel 100 continuously unwinds the web tape 200, the web tape 200 first passes through the vertically arranged sixth guide rollers 1013 for guiding, and then passes between the overhead roller 1015 and the third pressure roller 1016. The third pressure roller 1016 presses the web tape 200 against the overhead roller 1015. Subsequently, the overhead roller 1015 is driven to rotate. Under the action of the frictional force generated between the surface of the overhead roller 1015 and the surface of the web tape 200, a pulling force is generated on the unwound web tape 200 to achieve the conveyance of the web tape 200. In addition, a second driving part 10151 for driving the rotation of the overhead roller 1015 is installed beside the first support frame 101, and a tensioning assembly 1014 for tensioning the web tape 200 during the conveyance process is installed between the overhead roller 1015 and the sixth guide roller 1013; after the web tape 200 passes through the vertically arranged sixth guide rollers 1013, it is wound around the tensioning assembly 1014, and then passes between the overhead roller 1015 and the third pressure roller 1016. During the conveyance of the web tape 200, the tensioning assembly 1014 is operated to keep the web tape 200 in a tensioned state all the time, and the tension remains constant. Under the action of the tensioning assembly 1014, not only can the situation of slipping during the conveyance of the web tape 200 through the overhead roller 1015 be prevented, but also the web tape 200 can be prevented from wrinkling, which affects the subsequent processing accuracy.

[0062] As Figures 5 - 6As shown in the figure, the driving component 108 includes a first rotating shaft 1081 rotatably arranged on the columns vertically extending on both sides of the U-shaped frame 103. One end of the first rotating shaft 1081 is fixedly provided with a driving gear 107. The driving component 108 further includes a first support plate 1082 installed on the columns vertically extending on both sides of the U-shaped frame 103. A second rotating shaft 1083 with an axis parallel to that of the first rotating shaft 1081 is rotatably arranged on the first support plate 1082. One end of the second rotating shaft 1083 is drivingly connected to the first rotating shaft 1081 through a first transmission component 1084. A third rotating shaft 1085 coaxial with the first support shaft 102 is rotatably arranged on the first support frame 101. The first support shaft 102 is hollow. One end of the third rotating shaft 1085 passes through the first support shaft 102 and is drivingly connected to the end of the second rotating shaft 1083 away from the first transmission component 1084 through a second transmission component 1086. The first support frame 101 is provided with a first driving motor 1087, and the output shaft of the first driving motor 1087 is drivingly connected to the end of the third rotating shaft 1085 away from the second transmission component 1086 through a third transmission component 1088. When it is necessary to drive the air-expansion shaft 105 to rotate for paper feeding, the first driving motor 1087 is operated. Under the driving action of the third transmission component 1088, the third rotating shaft 1085 is driven to rotate. Subsequently, through the transmission of the second transmission component 1086, the second rotating shaft 1083 is driven to rotate. Finally, through the transmission of the first transmission component 1084, the driving gear 107 is driven to rotate. In cooperation with the driven gear 106, the air-expansion shaft 105 is driven to rotate. In addition, since the first support shaft 102 is hollow and one end of the third rotating shaft 1085 passes through the inside of the first support shaft 102, when the first support shaft 102 rotates, it will not be interfered by the third rotating shaft 1085. The first transmission component 1084, the second transmission component 1086, and the third transmission component 1088 have the same structure and the same transmission method, and are all gear-to-toothed belt transmission structures.

[0063] As Figure 7As shown in the figure, the tensioning assembly 1014 includes a plurality of upper rollers 10141 rotatably arranged on the first support frame 101. The plurality of upper rollers 10141 are placed between the overhead roller 1015 and the sixth guide roller 1013 and are at the same level. A vertically arranged first guide rod 10142 is installed on the inner side wall of the first support frame 101. A lifting frame 10143 is slidably arranged up and down on the first guide rod 10142. A plurality of lower rollers 10144 are rotatably arranged on the lifting frame 10143 at the same level and below the upper rollers 10141. The section of the paper tape 200 between the overhead roller 1015 and the sixth guide roller 1013 is wound around the plurality of upper rollers 10141 and the plurality of lower rollers 10144, so that the movement track of the paper tape 200 is arranged in a wavy shape. A pressure sensor for detecting the tension of the paper tape 200 is provided between the upper roller 10141 and the first support frame 101, or between the lower roller 10144 and the lifting frame 10143. When the pressure sensor detects that the paper tape 200 is not tensioned, the lifting frame 10143 is controlled to move downward, and the upper roller 10141 and the lower roller 10144 move away from each other, so that the paper tape 200 wound around the upper roller 10141 and the lower roller 10144 can be tensioned. Moreover, the pressure sensor can adjust the position of the lifting frame 10143 in real time according to the detected different pressures, so that the paper tape 200 always maintains a fixed tension (the pressure detected by the pressure sensor remains consistent) when it is tensioned, preventing the paper tape 200 from being torn.

[0064] In this embodiment, in order to control the automatic up and down movement of the lifting frame 10143, a pair of third transmission gears 10145 arranged up and down are rotatably installed on the inner side wall of the first support frame 101. The third transmission gears 10145 arranged up and down are on the same straight line in the vertical direction. A second transmission belt 10146 is wound around the third transmission gears 10145 arranged up and down, and a part of the second transmission belt 10146 is fixedly arranged with the lifting frame 10143 through a connecting block 10148. The first support frame 101 is also equipped with a first driving part 10147 for driving one of the third transmission gears 10145 to rotate. When it is necessary to control the up and down movement of the lifting frame 10143, the first driving part 10147 is operated, so as to drive the third transmission gear 10145 to rotate, so as to drive the second transmission belt 10146 to move. The second transmission belt 10146 drives the lifting frame 10143 to move up and down on the first guide rod 10142, realizing the control of the tension of the paper tape 200, so that the paper tape 200 always remains in a tensioned state and the tension remains constant. Finally, the paper tape 200 is pulled out by the overhead roller 1015. In addition, both the first driving part 10147 and the second driving part 10151 are prior arts and can be driving components such as motors.

[0065] In this embodiment, a conveying platform 1017 for connecting with the deviation rectifying mechanism 2 is provided at the end of the conveying track of the paper tape 200. The conveying platform 1017 supports the paper tape 200 during the conveying process. After the paper tape 200 passes between the overhead roller 1015 and the third pressing roller 1016, it will be placed on the top surface of the conveying platform 1017. Under the action of the overpass of the conveying platform 1017, it is convenient to continuously convey the paper tape 200 to the subsequent deviation rectifying mechanism 2. In addition, a negative pressure chamber 1018 for generating a downward suction force on the paper tape 200 during the conveying process is provided between the conveying platform 1017 and the overhead roller 1015. An air extraction module 1019 for generating negative pressure in the negative pressure chamber 1018 is installed at the bottom of the negative pressure chamber 1018. The air extraction module 1019 can be a device such as a blower that can extract air. Before the paper tape 200 is placed on the top surface of the conveying platform 1017, it will pass above the negative pressure chamber 1018, and the negative pressure chamber 1018 generates a downward suction force on the paper tape 200 during the conveying process, ensuring that the paper tape 200 always adheres to the top surface of the conveying platform 1017 during the conveying process and preventing the paper tape 200 from floating, which may affect subsequent processing.

[0066] As Figure 8 shown, the paper folding mechanism 3 includes a machine frame 301. The machine frame 301 is equipped with a first indentation mechanism 4 for continuously conveying the unfolded paper tape 200 and performing indentation treatment on its surface. It is also equipped with a right edge folding assembly 303 and a left edge folding assembly 305 arranged in sequence along the conveying direction of the paper tape 200. The left edge folding assembly 305 and the right edge folding assembly 303 are respectively used for folding the left and right length edges of the unfolded paper tape 200. The machine frame 301 is equipped with a roller conveying assembly 306 placed at the end of the conveying track of the paper tape 200 and used for continuously conveying the folded paper tape 200. The deviation rectifying mechanism 2 is connected to the first indentation mechanism 4 to perform deviation rectifying treatment on the paper tape 200 during the conveying process.

[0067] The roller conveying assembly 306 is connected to the cutting mechanism 5. Before operating this paper folding mechanism 3, first lay the paper tape 200. The staff first passes the paper tape 200 through the deviation rectifying mechanism 2 and the first indentation mechanism 4 in sequence, then folds the right length edge of the end section of the paper tape 200 and allows the folded section to pass through the right edge folding assembly 303. Under the action of the right edge folding assembly 303, the right length edge of the paper tape 200 continuously transitions from the unfolded state to the folded state during the conveying process. Subsequently, the staff folds the left length edge of the end section of the paper tape 200, and after folding, allows it to pass through the left edge folding assembly 305. Under the action of the left edge folding assembly 305, the left length edge of the paper tape 200 continuously transitions from the unfolded state to the folded state during the conveying process (as Figure 17 shown), and the paper tape 200 passes through the roller conveying assembly 306 after being folded left and right twice, and the roller conveying assembly 306 clamps and conveys the folded paper tape 200.

[0068] When folding paper, the deviation rectifying mechanism 2, the first indentation mechanism 4 and the roller conveying assembly 306 are started simultaneously. The first indentation mechanism 4 drives the continuously conveying of the paper tape 200 in the unfolded state. During the conveying process, the deviation rectifying mechanism 2 monitors the position of the paper tape 200 in real time. When the conveying trajectory of the paper tape 200 deviates, the deviation rectifying mechanism 2 straightens the paper tape 200 to make the paper tape 200 always convey in one direction. After being conveyed onto the right folding edge assembly 303, since the right long side of the paper tape 200 reaching the right folding edge assembly 303 is in a folded state while the paper tape 200 located at the first indentation mechanism 4 is in an unfolded state, during the continuous conveying of the paper tape 200, it can gradually transition from the unfolded state to the state where the right long side is in a folded state, and the folding process is natural and smooth. Similarly, the right long side of the paper tape 200 is folded and then conveyed onto the left folding edge assembly 305. Since the left long side of the paper tape 200 reaching the left folding edge assembly 305 is in a folded state while the right long side of the paper tape 200 located at the right folding edge assembly 303 is in a folded state, during the continuous conveying of the paper tape 200, the paper tape 200 with the right long side in a folded state can be gradually transitioned to the paper tape 200 with both the left and right long sides in a folded state (as Figure 17 shown). Finally, the roller conveying assembly 306 clamps and conveys the folded paper tape 200 to the subsequent cutting mechanism 5 for cutting treatment.

[0069] In addition, during the process of the first indentation mechanism 4 continuously conveying the paper tape 200 in the unfolded state, it will indent the surface of the paper tape 200 to press out traces in the form of dotted lines or straight lines, so as to improve the folding efficiency and avoid the situation of the paper tape 200 being folded crookedly in the subsequent paper folding processes by the left folding edge assembly 305 and the right folding edge assembly 303.

[0070] In this embodiment, the left hemming component 305 and the right hemming component 303 can move horizontally along the width direction of the paper tape 200 on the frame 301. Specifically, at least two first threaded rods 302 and at least two second threaded rods 304 are rotatably installed on the frame 301. The length directions of the first threaded rod 302 and the second threaded rod 304 are both parallel to the width direction of the paper tape 200 during the conveying process. The right hemming component 303 is threadedly connected to the first threaded rod 302, and the left hemming component 305 is threadedly connected to the second threaded rod 304. When driving the multiple first threaded rods 302 to rotate synchronously, the right hemming component 303 can be controlled to move horizontally along the width direction of the paper tape 200 on the frame 301. Similarly, when driving the multiple second threaded rods 304 to rotate synchronously, the left hemming component 305 can be controlled to move horizontally along the width direction of the paper tape 200 on the frame 301. By controlling the positions of the left hemming component 305 and the right hemming component 303, the folding positions of the left and right length sides of the paper tape 200 can be adjusted, so as to fold the paper tape 200 into different states. Moreover, the positions of the two can also be adjusted according to the paper tape 200 with different widths, so as to fold the paper tape 200 with different widths.

[0071] In addition, a second indentation mechanism 41 with the same function as the first indentation mechanism 4 is provided between the right hemming component 303 and the left hemming component 305, and the second indentation mechanism 41 and the first indentation mechanism 4 are controlled separately. When it is necessary to fold only the right length side of the paper tape 200, the second threaded rod 304 is driven to rotate to control the left hemming component 305 to deviate from the conveying track of the paper tape 200, and the first indentation mechanism 4 only presses out an indentation on the surface of the paper tape 200, so as to fold only the right length side of the paper tape 200. Similarly, the first threaded rod 302 is driven to rotate to control the right hemming component 303 to deviate from the conveying track of the paper tape 200, and the second indentation mechanism 41 only presses out an indentation on the surface of the paper tape 200, so as to fold only the left length side of the paper tape 200.

[0072] Such as Figures 9 - 11As shown, the deviation correction mechanism 2 includes a base 201 and a bracket 202 arranged on the base 201. A pair of paper guide rollers 203 arranged in parallel and used to receive the paper tape 200 conveyed from the outside are provided on the top of the bracket 202. The axes of the paper guide rollers 203 are arranged horizontally and fixed to the top of the bracket 202. The paper guide rollers 203 are connected to the paper output end of the paper feeding mechanism 1. By running the paper feeding mechanism 1, the paper tape 200 can be continuously fed out, and then received by the paper guide rollers 203 and wound around the pair of paper guide rollers 203 to guide the paper tape 200. Among them, a third conveying roller 205 with an axis parallel to the axis of the paper guide roller 203 is rotatably provided on the top of the bracket 202, and the conveyed paper tape 200 is sequentially wound around the paper guide roller 203 and the third conveying roller 205; by driving the third conveying roller 205 to rotate, the paper tape 200 is conveyed under the action of the friction between the surface of the third conveying roller 205 and the surface of the paper tape 200, and is conveyed to the subsequent correction position to correct the paper tape 200.

[0073] In this embodiment, each paper guide roller 203 is provided with a pair of limiting members 204 for limiting the paper tape 200 during the conveying process, and the distance between the limiting members 204 is adjustable. The distance between the two limiting members 204 is adjusted according to the width of the paper tape 200, and the paper tape 200 wound on the paper guide roller 203 is limited by the limiting members 204, and in cooperation with the third conveying roller 205, the paper tape 200 is always conveyed in one direction.

[0074] In order to drive the third conveying roller 205 to rotate, a second driving motor 207 is installed on the top of the bracket 202, and the output shaft of the second driving motor 207 is connected to one end of the third conveying roller 205 through a fourth transmission component 208; the fourth transmission component 208 is an existing structure, which can be a gear and a toothed belt structure, and the second driving motor 207 is operated to drive the third conveying roller 205 to rotate under the transmission action of the fourth transmission component 208. A brush 206 for cleaning the surface of the paper tape 200 is installed beside the paper guide roller 203. When the paper tape 200 is wound on the paper guide roller 203, its surface will contact the bristles of the brush 206. In the process of driving the third conveying roller 205 to rotate to continuously convey the paper tape 200, the brush 206 automatically cleans the surface of the paper tape 200 to brush away the paper scraps or dust attached to its surface, so as to facilitate the subsequent processing of the paper tape 200.

[0075] Furthermore, the deviation rectifying mechanism 2 further includes a swing frame 209. The initial end of the swing frame 209 is close to the support 202. The base 201 is provided with a fixed shaft 2010 arranged vertically in the axial direction, and the middle position of the initial end of the swing frame 209 is rotatably connected to the fixed shaft 2010. By setting the fixed shaft 2010, the swing frame 209 can swing back and forth on the base 201 around the axis of the fixed shaft 2010. The initial end and the terminal end of the swing frame 209 are respectively provided with a second deviation rectifying roller 2012 and a first deviation rectifying roller 2011 at the same height, and the axes of the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 are both parallel to the axis of the third conveying roller 205; the heights of the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 are lower than the height of the third conveying roller 205. During the conveying process, the paper tape 200 passes under the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 and is in close contact with their surfaces. During the process of driving the third conveying roller 205 to rotate to continuously convey the paper tape 200, the paper tape 200 is first conveyed downward, then passes under the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012, from the initial end to the terminal end of the swing frame 209, and finally conveyed upward to be conveyed to the first indentation mechanism 4. During the conveying process, the paper tape 200 is always in a taut state; during the process of the paper tape 200 being conveyed along the above trajectory, the position of the continuously conveyed paper tape 200 is sensed by a sensor (not shown in the figure). When it is sensed that the paper tape 200 is deflected, the swing frame 209 is controlled to swing around the axis of the fixed shaft 2010. Under the frictional force when the surface of the paper tape 200 is in close contact with the surfaces of the two deviation rectifying rollers (i.e., the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012), the conveying direction of the paper tape 200 can be adjusted to straighten it, thereby realizing the deviation rectifying process and preventing errors from occurring during the subsequent paper folding process of the paper tape 200.

[0076] In this embodiment, in order to control the swing of the swing frame 209, the deviation rectifying mechanism 2 further includes an adjustment cylinder 2015 arranged horizontally. The base 201 is provided with a first fixing member 2016, and the end of the swing frame 209 is provided with a second fixing member 2017. The end of the adjustment cylinder 2015 is hinged to the first fixing member 2016 through a hinge shaft, and the end of the telescopic rod of the adjustment cylinder 2015 is hinged to the second fixing member 2017 through a hinge shaft. The hinge shafts on the first fixing member 2016 and the second fixing member 2017 are both arranged vertically. After the sensor senses that the paper tape 200 is deflected during the conveying process, the adjustment cylinder 2015 is operated to control the telescopic movement of its telescopic rod, so as to drive the swing frame 209 to swing back and forth around the axis of the fixed shaft 2010, and correct the deviation of the paper tape 200. A first protective housing 2018 for protecting the paper tape 200 is installed below the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012. The first protective housing 2018 is fixedly arranged at the bottom of the base 201. Since the height positions of the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 are set relatively low, under the action of the first protective housing 2018, the paper tape 200 is isolated from the ground, preventing the paper tape 200 from contacting the ground when it is not in a taut state (before the paper tape 200 is continuously conveyed, the staff needs to manually pass the paper tape 200 under the first deviation rectifying roller 2011 and the second deviation rectifying roller 2012 for loading), so that the paper tape 200 will not be attached with dust.

[0077] Further, during the process of the adjustment cylinder 2015 controlling the swing of the swing frame 209, in order to improve the stability of the swing frame 209 during swinging, a second guiding part 2014 and a first guiding part 2013 are respectively installed at the initial end and the end of the swing frame 209. There are at least two second guiding parts 2014 and first guiding parts 2013, and they are symmetrically arranged based on the fixed shaft 2010, that is, the second guiding part 2014 is symmetrically arranged based on the fixed shaft 2010, and the first guiding part 2013 is symmetrically arranged based on the fixed shaft 2010. By respectively installing the second guiding part 2014 and the first guiding part 2013 at the initial end and the end of the swing frame 209, the swing frame 209 can be more stable during swinging.

[0078] The first guiding part 2013 includes a first guide rail 20131 installed on the base 201. The swinging frame 209 is provided with a first fixing block 20132, and the first fixing block 20132 is rotatably provided with a first roller 20133. The first roller 20133 can roll within the first guide rail 20131. Secondly, the second guiding part 2014 includes a second guide rail 20141 installed on the swinging frame 209. The base 201 is provided with a second fixing block 20142, and the second fixing block 20142 is rotatably provided with a second roller 20143. The second roller 20143 can roll within the second guide rail 20141. When the swinging frame 209 swings, it drives the first roller 20133 and the second guide rail 20141 to move around the axis of the fixed shaft 2010. At this time, the first roller 20133 rolls within the first guide rail 20131, and the second roller 20143 rolls within the second guide rail 20141, realizing the guiding of the swinging frame 209 and improving the stability during swinging. In addition, both the first guide rail 20131 and the second guide rail 20141 can be set as arc-shaped guide rails with a curvature, and the center point of the curvature coincides with the axis of the fixed shaft 2010. By setting the arc-shaped guide rails, the guiding effect on the swinging frame 209 is improved.

[0079] As Figures 12 - 15 shown, the right folding edge assembly 303 includes a support frame 3031 threadedly connected to the first threaded rod 302. The support frame 3031 is equipped with a first support plate 3032 and a second support plate 3033 that are arranged in sequence along the conveying direction of the paper tape 200 and are used to support the paper tape 200 during the folding process. The first support plate 3032 is arranged obliquely from bottom to top, and the second support plate 3033 is arranged obliquely from top to bottom. The end of the first support plate 3032 at the higher position is connected to the starting end of the second support plate 3033 at the higher position. A turning roller 3034 for turning the paper tape 200 during the folding process is rotatably provided between the two ends of the connection. The turning roller 3034 is arranged horizontally and perpendicular to the conveying direction of the paper tape 200. A folding edge guiding inclined block 3035 for guiding the right length edge of the paper tape 200 to be bent is arranged beside the right end of the turning roller 3034. During the continuous conveying of the paper tape 200, the paper tape 200 first passes through the first support plate 3032 to be conveyed from bottom to top. Under the turning action of the turning roller 3034, the paper tape 200 then passes through the second support plate 3033 to be conveyed from top to bottom. During the process of turning from the first support plate 3032 to the second support plate 3033, under the guiding action of the folding edge guiding inclined block 3035, the right length edge of the paper tape 200 is bent and folded, gradually transitioning from the unfolded state to the state where the right length edge is in a folded state, thus realizing the continuous folding process.

[0080] In addition, a limiting lever 3036 for limiting the paper tape 200 with its right long side in a folded state is provided on the right side of the second supporting plate 3033. After the right long side of the paper tape 200 is folded, it is limited by the limiting lever 3036 during the conveying process to prevent deviation. A number of third supporting rods 3037 arranged in an array along the conveying direction of the paper tape 200 are provided on the limiting lever 3036, and each third supporting rod 3037 is provided with a paper pressing and limiting piece 3038 for flattening the folded edge of the paper tape 200. During the process of the folded paper tape 200 being conveyed, the folded edge passes between the paper pressing and limiting piece 3038 and the surface of the second supporting plate 3033. Under the action of the pressure applied by the paper pressing and limiting piece 3038, the folded edge of the paper tape 200 is flattened, improving the folding effect; the paper pressing and limiting piece 3038 also has the function of limiting and guiding the paper tape 200, improving the conveying efficiency.

[0081] The right folding edge assembly 303 and the left folding edge assembly 305 are symmetrically arranged one after the other based on the conveying track of the paper tape 200. The folding edge guiding inclined block 3035 on the right folding edge assembly 303 is arranged beside the right end of the turning roller 3034, while the folding edge guiding inclined block 3035 on the left folding edge assembly 305 is arranged beside the left end of the turning roller 3034. Therefore, the left long side of the guiding paper tape 200 is bent and then folded, gradually transitioning from the state where the right long side is folded to the state where both the left and right long sides are folded.

[0082] As Figure 16 shown, the roller conveying assembly 306 includes a first supporting frame body 3061 installed on the frame 301. The first supporting frame body 3061 is rotatably provided with a first conveying roller 3062 whose axis is horizontally arranged and perpendicular to the conveying direction of the paper tape 200. A first fixing frame 3063 is also provided. The first fixing frame 3063 is rotatably provided with a first pressing roller 3064 for pressing the paper tape 200 against the first conveying roller 3062. The first fixing frame 3063 can rotate on the first supporting frame body 3061, thereby driving the first pressing roller 3064 to approach or move away from the first conveying roller 3062. The first conveying roller 3062 receives the folded paper tape 200. After the paper tape 200 passes between the first conveying roller 3062 and the first pressing roller 3064, the first fixing frame 3063 is controlled to rotate to drive the first pressing roller 3064 to approach the first conveying roller 3062, pressing the paper tape 200 against the first conveying roller 3062 through the first pressing roller 3064. Subsequently, the first conveying roller 3062 is driven to rotate. Under the action of the frictional force generated between the surface of the first conveying roller 3062 and the surface of the paper tape 200, a pulling force is generated on the paper tape 200, thereby realizing the continuous conveying of the paper tape 200.

[0083] In addition, the first support frame 3061 is also rotatably provided with a second conveying roller 3066 and a third threaded rod 3067 whose axes are parallel to the axis of the first conveying roller 3062. A number of control components 3068 are arranged on the third threaded rod 3067, and each control component 3068 is provided with a second pressing roller 3069 for flattening the paper tape 200 in a folded state. The control component 3068 is used to control the second pressing roller 3069 to approach or move away from the second conveying roller 3066. After the paper tape 200 in a folded state is conveyed by the first conveying roller 3062, it passes between the second conveying roller 3066 and the second pressing roller 3069. Subsequently, the control component 3068 is operated to control the second pressing roller 3069 to approach the second conveying roller 3066, and the paper tape 200 is pressed tightly against the second conveying roller 3066, thereby realizing the flattening process of the paper tape 200. The first pressing roller 3064 and the second pressing roller 3069 are set to be movable to facilitate the staff to lay the paper tape 200 in advance. Secondly, according to the different sizes of the paper tape 200 in a folded state, the third threaded rod 3067 can be driven to rotate to control the positions of the control components 3068, so as to adjust the flattening position and align the outermost second pressing roller 3069 with the edge of the paper tape 200 in a folded state.

[0084] The first support frame 3061 is provided with a first guiding roller 3065 disposed between the first conveying roller 3062 and the second conveying roller 3066, and is also provided with a second guiding roller 30610 for guiding the folded paper tape 200 to the subsequent cutting mechanism 5. The paper tape 200 in a folded state is wound around the first conveying roller 3062, the first guiding roller 3065, the second conveying roller 3066, and the second guiding roller 30610 in sequence along the conveying direction, and is guided during the conveying process, so that the paper tape 200 is conveyed along a specified direction.

[0085] As Figures 18 - 19 shown, the first indentation mechanism 4 includes a second support frame 401 and a fourth conveying roller 403 rotatably provided on the second support frame 401. The fourth conveying roller 403 is used for continuously conveying the paper tape 200; the second support frame 401 is also provided with a second fixing frame 404 and a number of third guiding rollers 402. The third guiding rollers 402 are used to receive the paper tape 200 sent by the deviation rectifying mechanism 2 and guide the paper tape 200 to be wound around the fourth conveying roller 403. The second fixing frame 404 is rotatably provided with a pressing roller 405 for pressing the paper tape 200 tightly against the fourth conveying roller 403. The paper tape 200 sent by the deviation rectifying mechanism 2 is received and guided by the third guiding rollers 402, so as to be guided to be wound around the fourth conveying roller 403, and passes between the fourth conveying roller 403 and the pressing roller 405. The paper tape 200 is pressed tightly against the fourth conveying roller 403 by the pressing roller 405. Subsequently, the fourth conveying roller 403 is driven to rotate, and under the action of the frictional force generated between the surface of the fourth conveying roller 403 and the surface of the paper tape 200, a pulling force is generated on the paper tape 200, thereby realizing the conveying of the paper tape 200.

[0086] During the conveying process, in order to indent the surface of the paper tape 200, a fourth threaded rod 407 with an axis parallel to the axis of the fourth conveying roller 403 is rotatably provided on the second support frame 401. A number of indentation parts 408 for indenting the surface of the paper tape 200 are installed on the fourth threaded rod 407. Below the indentation parts 408, there is a support roller 406 for supporting the paper tape 200 to be indented. The paper tape 200 during the conveying process passes through between the indentation parts 408 and the support roller 406. When indentation is required, the indentation parts 408 are operated to contact the surface of the paper tape 200 to be indented, and at the same time, they are supported by the support roller 406. During the conveying process of the paper tape 200, dotted or linear traces are pressed out on the surface of the paper tape 200, which is convenient for the subsequent paper folding process of the paper tape 200. In addition, there are a number of indentation parts 408. The same number of indentation parts 408 as the number of traces to be pressed are operated, and multiple traces can be pressed out simultaneously. By driving the fourth threaded rod 407 to rotate, the position of the indentation parts 408 can be adjusted, so as to adjust the position of the indentation to adapt to paper tapes 200 of different sizes.

[0087] In this embodiment, the second support frame 401 is further provided with a fourth guide roller 4010, which is used to guide the indented paper tape 200 to the right folding edge assembly 303 or the left folding edge assembly 305 for paper folding processing. The paper tape 200 passes through the third guide roller 402, between the indentation parts 408 and the support roller 406, between the fourth conveying roller 403 and the pressing roller 405, and the fourth guide roller 4010 in sequence. A second protective housing 4011 for protecting the paper tape 200 during the conveying process is installed beside the fourth guide roller 4010, to prevent the paper tape 200 from falling and contacting the ground and sticking to stains during the process of replacing the new paper tape 200 (the paper tape 200 is in a relaxed state during the laying process). The second support frame 401 is provided with a control panel 4012 for controlling the operation of the indentation parts 408 and the rotation of the fourth threaded rod 407. By operating the control panel 4012, the fourth threaded rod 407 can be rotated a specified number of turns, so as to adjust the indentation parts 408 to a specified position. And, it can also control the operation of the indentation parts 408 to contact the surface of the paper tape 200 for continuous indentation processing.

[0088] As Figure 20As shown, the indentation part 408 includes a first support base 4081 and a threaded sleeve 4082 installed on the first support base 4081. The threaded sleeve 4082 is threadedly connected to the fourth threaded rod 407. After controlling the rotation of the fourth threaded rod 407, under the cooperation of the threaded connection with the threaded sleeve 4082, the first support base 4081 is controlled to move along the axis of the fourth threaded rod 407. Among them, a limit housing 4089 is fixedly provided on the first support base 4081, and the second support frame 401 is provided with a limit cross beam 409 for contacting the limit housing 4089. When the fourth threaded rod 407 rotates counterclockwise (the rotation direction is based on Figure 19 ), the limit cross beam 409 is blocked by the limit housing 4089 to prevent the fourth threaded rod 407 from driving the first support base 4081 and the threaded sleeve 4082 to rotate together when rotating. By blocking the limit housing 4089 with the limit cross beam 409, the first support base 4081 can only move along the axis of the fourth threaded rod 407. In addition, the limit housing 4089 can also slide along the axis of the fourth threaded rod 407 on the limit cross beam 409, which can also play a role in limiting the first support base 4081.

[0089] A movable arm 40810 is rotatably provided at the bottom of the first support base 4081 through a pin. The axis of the pin on the first support base 4081 is parallel to the axis of the fourth threaded rod 407. Under the action of the pin, the movable arm 40810 can move around the axis of the pin. One end of the movable arm 40810 is provided with a second support shaft 40811 whose axis is parallel to the axis of the fourth conveying roller 403. A convex gear 40812 for contacting the surface of the paper tape 200 during conveying to make an indentation is rotatably provided on the second support shaft 40811. During the rotation of the fourth conveying roller 403 to convey the paper tape 200, the movable arm 40810 moves to drive the convex gear 40812 to move towards the direction close to the paper tape 200, so that the convex teeth on the circumference of the convex gear 40812 contact the surface of the paper tape 200. Under the action of the frictional force between the convex gear 40812 and the surface of the paper tape 200, the convex gear 40812 rolls on the surface of the paper tape 200 to press out a dotted line-shaped trace, and the paper tape 200 is automatically indented.

[0090] In order to control the movement of the movable arm 40810 on the first support base 4081, a pressing cylinder 40813 for pressing the movable arm 40810 to make the convex gear 40812 contact the surface of the paper tape 200 is installed on the first support base 4081. An installation member 40814 is provided at one end of the movable arm 40810 away from the second support shaft 40811. A second spring 40815 for applying a force to the movable arm 40810 to separate the convex gear 40812 from the surface of the paper tape 200 is provided between the installation member 40814 and the first support base 4081. After the pressing cylinder 40813 operates, the telescopic rod of the pressing cylinder 40813 extends to press the movable arm 40810, making the convex gear 40812 contact the surface of the paper tape 200. At this time, the second spring 40815 is compressed; after the telescopic rod of the pressing cylinder 40813 contracts, under the action of the thrust applied by the second spring 40815 to the movable arm 40810, the movable arm 40810 is pushed to reset, separating the convex gear 40812 from the surface of the paper tape 200, thereby stopping the indentation process.

[0091] In this embodiment, the threaded sleeve 4082 is rotatably arranged with the first support base 4081. A sliding chamber 4083 is formed inside the first support base 4081. An electromagnet 4084 that can move in a direction close to or away from the threaded sleeve 4082 is arranged in the sliding chamber 4083. After being energized, the electromagnet 4084 moves in a direction close to the threaded sleeve 4082 to attract it, and after being powered off, the electromagnet 4084 moves in a direction away from the threaded sleeve 4082 to separate from it. When the electromagnet 4084 separates from the threaded sleeve 4082, the fourth threaded rod 407 is controlled to rotate, driving the threaded sleeve 4082 to rotate together, so that the threaded sleeve 4082 idles on the first support base 4081, and thus the first support base 4081 cannot be controlled to move along the axis of the fourth threaded rod 407 (that is, the position of the indentation part 408 cannot be adjusted); since there are multiple indentation parts 408 on the fourth threaded rod 407, when only the position of one indentation part 408 needs to be adjusted, the electromagnet 4084 in this indentation part 408 is energized (the electromagnets 4084 in other indentation parts 408 are not energized), so that the electromagnet 4084 attracts the threaded sleeve 4082. After the fourth threaded rod 407 rotates, the threaded sleeve 4082 on this indentation part 408 will not idle (the threaded sleeves 4082 on other indentation parts 408 will idle), and thus the position of this indentation part 408 can be controlled to move along the axis of the fourth threaded rod 407 to achieve position adjustment. In addition, the positions of multiple indentation parts 408 can also be adjusted simultaneously. When the position of a certain indentation part 408 needs to be adjusted, the electromagnet 4084 is energized.

[0092] After the electromagnet 4084 is powered off, in order to separate the electromagnet 4084 from the threaded sleeve 4082, a third fixing member 4085 is provided on the top of the first support seat 4081. A second guide rod 4086 is slidably arranged on the third fixing member 4085, and the bottom end of the second guide rod 4086 is fixedly arranged with the electromagnet 4084. Under the action of the second guide rod 4086, the electromagnet 4084 can slide up and down on the third fixing member 4085 (that is, move in the direction of approaching or departing from the threaded sleeve 4082). A limit block 4087 is arranged at the top end of the second guide rod 4086, and a first spring 4088 for applying an upward thrust to the limit block 4087 to drive the electromagnet 4084 to reset is arranged between the limit block 4087 and the third fixing member 4085. When the electromagnet 4084 is powered on, the electromagnet 4084 moves in the direction of approaching the threaded sleeve 4082, so as to attract the threaded sleeve 4082. At this time, the first spring 4088 is compressed; when the electromagnet 4084 is powered off, under the action of the compressed first spring 4088, an upward thrust is applied to the limit block 4087, so as to drive the electromagnet 4084 to reset in the direction of departing from the threaded sleeve 4082, realizing the separation of the electromagnet 4084 from the threaded sleeve 4082.

[0093] As Figures 21 - 23 shown, the cutting mechanism 5 includes a support housing 501 and a third support frame 502 installed on the support housing 501. An upper conveying roller 503 and a lower conveying roller 504 which are arranged up and down and used for clamping and conveying the paper tape 200 are rotatably arranged on the third support frame 502. The axes of the upper conveying roller 503 and the lower conveying roller 504 are horizontally arranged and are consistent with the width direction of the paper tape 200; the folded paper tape 200 passes between the upper conveying roller 503 and the lower conveying roller 504, and the paper tape 200 is clamped, and then the two are driven to rotate in opposite directions. Under the action of the friction force between the surfaces of the two and the surface of the paper tape 200, the continuous conveying of the paper tape 200 is realized. A plurality of soft rubber wheels 505 for increasing the friction force are arranged on the surface of the upper conveying roller 503. Under the action of arranging the plurality of soft rubber wheels 505, the friction force between the surface of the upper conveying roller 503 and the surface of the paper tape 200 is increased, and the situation of slipping will not occur during the process of conveying the paper tape 200. Soft rubber wheels 505 can also be arranged on the lower conveying roller 504 at the same time, and the anti-slip effect is more obvious.

[0094] Among them, the third support frame 502 is provided with a fixed seat 507 and a rotating roller 508 which are arranged up and down and placed on the conveying track of the paper tape 200, the upper conveying roller 503 and the lower conveying roller 504 are arranged up and down in the front, and the fixed seat 507 and the rotating roller 508 are arranged up and down in the back, and are arranged in sequence along the conveying track of the paper tape 200; the fixed seat 507 and the rotating roller 508 are on a straight line in the same vertical direction, and the fixed seat 507 is fixedly set on the third support frame 502, and the rotating roller 508 is rotatably set on the third support frame 502; a cutting knife pad 5071 is installed at the bottom of the fixed seat 507, and the rotating roller 508 is installed with a cutting knife 509 used to cooperate with the cutting knife pad 5071 to cut the conveyed paper tape 200 into paper segments.

[0095] The paper tape 200 passes through the upper conveying roller 503 and the lower conveying roller 504 and between the fixed seat 507 and the rotating roller 508 in sequence, and the paper tape 200 is uniformly conveyed by the upper conveying roller 503 and the lower conveying roller 504, and at the same time, the rotating roller 508 is driven to rotate clockwise (the rotation direction is Figure 23 As a reference), the rotating roller 508 rotates around its axis with the cutting knife 509 to rotate until it contacts the cutting knife pad 5071 on the fixed seat 507. The cutting knife 509 is responsible for applying force to the paper tape 200 for cutting, and the cutting knife pad 5071 is responsible for receiving the force, and the paper tape 200 is cut under the action of force transmission; the paper tape 200 is transported at a uniform speed, and the rotating roller 508 and the cutting knife 509 are continuously rotated, so that the paper tape 200 is continuously cut. In addition, when the size of the paper tape 200 needs to be adjusted, the rotation speed of the rotating roller 508 can be controlled. When the rotating roller 508 becomes faster, the cut paper becomes shorter, and when the rotating roller 508 becomes slower, the cut paper becomes longer.

[0096] A second support plate 506 for supporting and guiding the paper tape 200 is provided between the lower conveying roller 504 and the rotating roller 508; during the conveying process of the paper tape 200, the second support plate 506 accurately guides the paper tape 200 to between the fixed seat 507 and the rotating roller 508, and can also prevent the paper tape 200 from automatically falling off after cutting.

[0097] In order to drive the rotating roller 508 to rotate, the third supporting frame 502 is equipped with a second servo motor 5010, and the output shaft of the second servo motor 5010 is connected to one end of the rotating roller 508 through a fifth transmission component 5011; the fifth transmission component 5011 is an existing structure, which can be a gear and a toothed belt structure, and the second servo motor 5010 is operated to drive the rotating roller 508 to rotate at a constant speed under the transmission effect of the fifth transmission component 5011. In addition, the rotation speed of the rotating roller 508 can also be controlled by the second servo motor 5010, thereby controlling the size of the cut paper.

[0098] In this embodiment, the third support frame 502 is further provided with a guiding frame 5015. The guiding frame 5015 is used to connect with the paper folding mechanism 3. The paper folding mechanism 3 is used to fold the paper tape 200, and then convey the folded paper tape 200 to the cutting mechanism 5 for cutting into paper. The guiding frame 5015 is provided with a number of fifth guiding rollers 5016 for guiding the folded paper tape 200 between the upper conveying roller 503 and the lower conveying roller 504. A support table 5017 for supporting the paper tape 200 during the movement process is arranged between the guiding frame 5015 and the lower conveying roller 504. The guiding frame 5015 receives the folded paper tape 200 conveyed by the paper folding mechanism 3, and guides it through the fifth guiding rollers 5016. Then, the folded paper tape 200 passes above the support table 5017 and is supported by it, and then passes between the upper conveying roller 503 and the lower conveying roller 504 to continue the conveying process of the folded paper tape 200, so as to be conveyed between the fixed seat 507 and the rotating roller 508 for cutting. In addition, the staff can judge the conveying situation of the paper tape 200, that is, whether there is deviation or paper jamming, by observing the folded paper tape 200 passing above the support table 5017.

[0099] Furthermore, the third support frame 502 is further provided with a third conveying table 5012 for conveying the cut paper. The top surface of the third conveying table 5012 is provided with a number of first conveying modules. The first conveying modules and the second servo motor 5010 run simultaneously. After the paper tape 200 is cut into paper, the paper is conveyed through the number of conveying modules on the third conveying table 5012. Moreover, the conveying speed of the paper by the first conveying modules is greater than the conveying speed of the paper tape 200, so that the papers in the conveying process on the third conveying table 5012 are distributed at intervals, which is convenient for the subsequent paper stacking process.

[0100] The first conveying module includes a first rotating rod 5013 rotatably arranged on the third conveying table 5012 and having an axis parallel to the axis of the rotating roller 508. A number of first conveying wheels 5014 are arranged on the first rotating rod 5013. After the paper is placed on the number of first conveying wheels 5014, by driving the first rotating rod 5013 to rotate, a number of first conveying wheels 5014 are driven to rotate synchronously to realize the continuous conveying of the paper.

[0101] Such as Figures 23 - 24As shown, a waste discharge port 5018 for discharging waste paper is formed on the top surface of the third conveying table 5012. A fourth rotating shaft 5019 with an axis parallel to the axis of the rotating roller 508 is rotatably arranged in the waste discharge port 5018. A baffle plate 5020 for blocking waste paper and guiding it into the waste discharge port 5018 is arranged on the fourth rotating shaft 5019. When waste discharge is not required, the plate surface of the baffle plate 5020 is flush with the top surface of the third conveying table 5012. At the same time, the baffle plate 5020 blocks the waste discharge port 5018. During the process of the first conveying wheel 5014 conveying the paper, the paper continuously passes above the plate surface of the baffle plate 5020, and the paper during the conveying process will not be blocked. When it is detected that the paper is cut, the fourth rotating shaft 5019 is controlled to rotate to drive the end of the baffle plate 5020 close to the cutting knife 509 to tilt up, thereby opening the waste discharge port 5018. Moreover, the baffle plate 5020 blocks the cut paper during the conveying process, and after blocking, it guides the cut paper into the waste discharge port 5018, and the cut paper is discharged below the third conveying table 5012 through the waste discharge port 5018 for collection. When good paper is detected, the fourth rotating shaft 5019 is controlled to rotate to drive the baffle plate 5020 to reset.

[0102] In order to control the rotation of the fourth rotating shaft 5019, a second rotating member 5021 is installed at one end of the fourth rotating shaft 5019. The second rotating member 5021 is formed with a sliding groove 5022. When the fourth rotating shaft 5019 rotates, the second rotating member 5021 drives the sliding groove 5022 to rotate around the axis of the fourth rotating shaft 5019. An electric push rod 5023 with a length direction perpendicular to the length direction of the fourth rotating shaft 5019 is installed beside the third conveying table 5012. A push rod 5024 with a length direction parallel to the length direction of the fourth rotating shaft 5019 is installed at the end of the telescopic rod of the electric push rod 5023. The push rod 5024 is slidably placed in the sliding groove 5022. When the plate surface of the baffle plate 5020 is flush with the top surface of the third conveying table 5012, the sliding groove 5022 on the second rotating member 5021 is arranged vertically. When waste discharge is required, the electric push rod 5023 is operated, and the telescopic rod extends to drive the push rod 5024 to move. The push rod 5024 applies a thrust to the second rotating member 5021 and slides in the sliding groove 5022 to push the second rotating member 5021 to rotate counterclockwise (the rotation direction is based on Figure 24 as a reference), and the end of the baffle plate 5020 close to the cutting knife 509 can be controlled to tilt up to achieve waste discharge.

[0103] As Figures 25 - 26As shown in the figure, the paper feeding mechanism 6 includes a second support frame 601 and a fourth support frame 602 installed on the second support frame 601. The fourth support frame 602 is equipped with a paper feeding table 603 for feeding the paper. A number of second conveying modules are arranged on the top surface of the paper feeding table 603. Above the paper feeding table 603, there is a first limiting plate body 606 for limiting the paper during the conveying process. 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 body 606. The feeding port of the paper feeding channel 607 is connected to the paper outlet end of the cutting mechanism 5. After the cutting mechanism 5 cuts the paper tape 200 into papers, the papers are sent into the paper feeding channel 607, and then the rotation of a number of second conveying modules on the paper feeding table 603 is controlled to realize the continuous feeding of the papers. In addition, during the conveying process, the first limiting plate body 606 is used to limit the paper to prevent the paper from deviating or departing from the conveying track.

[0104] Among them, the second conveying module includes a second rotating rod 604 with a horizontally arranged axis perpendicular to the conveying direction of the paper. The second rotating rod 604 is rotatably arranged on the paper feeding table 603, and a number of second conveying wheels 605 are provided on the second rotating rod 604. After the paper is sent into the paper feeding channel 607, the paper is placed on a number of second conveying wheels 605. By driving the rotation of the second rotating rod 604 to drive the synchronous rotation of a number of second conveying wheels 605, the paper can be conveyed.

[0105] Furthermore, the fourth support frame 602 is provided with a first conveying table 608 connected to the outlet of the paper feeding channel 607, and a second conveying table 6010 connected to the outlet of the paper feeding channel 607 is also provided. Both the first conveying table 608 and the second conveying table 6010 are used for conveying the paper. The conveying direction of the first conveying table 608 can be the same as that of the paper feeding table 603, and the conveying direction of the second conveying table 6010 is arranged obliquely upward relative to the conveying direction of the paper feeding table 603. The top surfaces of both the first conveying table 608 and the second conveying table 6010 are provided with the second conveying modules as described above. An adjusting component for controlling the selective connection between the first conveying table 608 and the paper feeding channel 607 or between the second conveying table 6010 and the paper feeding channel 607 is installed at the outlet of the paper feeding channel 607.

[0106] By setting the adjusting component, it is possible to control the connection between the initial end of the first conveying table 608 and the discharge port of the paper feeding channel 607, or the connection between the initial end of the second conveying table 6010 and the discharge port of the paper feeding channel 607; specifically: when the first conveying table 608 is connected to the paper feeding channel 607, the second conveying table 6010 is in a disconnected state from the paper feeding channel 607. The paper feeding table 603 conveys the paper to the top surface of the first conveying table 608, and then the second conveying module provided on the top surface of the first conveying table 608 continues to convey the paper. After operating the adjusting component, it is possible to control the connection between the second conveying table 6010 and the paper feeding channel 607, while the first conveying table 608 is in a disconnected state from the paper feeding channel 607. The paper feeding table 603 conveys the paper to the top surface of the second conveying table 6010, and then the second conveying module provided on the top surface of the second conveying table 6010 continues to convey the paper. With the cooperation of the first conveying table 608, the second conveying table 6010 and the adjusting component, the layered conveying of the paper is realized, and the paper is conveyed to different positions for palletizing and stacking, which can not only achieve classified stacking, but also improve the subsequent stacking efficiency. A second limiting plate body 609 is provided above the first conveying table 608, and a third limiting plate body 6011 is provided above the second conveying table 6010. The functions of the first limiting plate body 606, the second limiting plate body 609 and the third limiting plate body 6011 are the same, and all are used to limit the paper to prevent the paper from deviating or departing from the conveying track during the conveying process.

[0107] In this embodiment, the second support frame 601 is also provided with a first alignment conveying part 6014 and a second alignment conveying part 6015 for conveying the paper and aligning the paper during the conveying process. The initial end of the first alignment conveying part 6014 is connected to the end of the first conveying table 608, and the initial end of the second alignment conveying part 6015 is connected to the end of the second conveying table 6010. After the paper is respectively conveyed onto the first conveying table 608 and the second conveying table 6010, the first conveying table 608 and the second conveying table 6010 continue to convey the paper to be respectively conveyed onto the first alignment conveying part 6014 and the second alignment conveying part 6015. The first alignment conveying part 6014 and the second alignment conveying part 6015 also convey the paper, and adjust the position of the paper during the conveying process to adjust the paper to an aligned state arranged in a straight line array, which is convenient for subsequent palletizing and stacking of the paper to make the paper stack neat.

[0108] The stacking mechanism 7 includes a fixed frame 701 provided at the end of the second support frame 601. The fixed frame 701 is equipped with a first stacking member 702 for connecting to the end of the first alignment conveying section 6014, and a second stacking member 703 for connecting to the end of the second alignment conveying section 6015. The first stacking member 702 and the second stacking member 703 are arranged vertically and are both used for palletizing and stacking the adjusted papers. After the first alignment conveying section 6014 and the second alignment conveying section 6015 adjust and align the papers in different conveying paths respectively, they are respectively conveyed onto the first stacking member 702 and the second stacking member 703. The two operate simultaneously to perform palletizing and stacking processing on the conveyed papers. How to stack specifically will be described below.

[0109] The first alignment conveying section 6014 and the second alignment conveying section 6015 have the same structure and the same operating mode. As Figures 27 - 28 shown, the first alignment conveying section 6014 includes a second support base 60141 and a support platform 60142 installed on the second support base 60141. The support platform 60142 is used to support the paper during the adjustment process. Among them, a first pulley 60143 is rotatably provided at the initial end of the second support base 60141, and a second pulley 60144 is rotatably provided at its end. The first pulley 60143 is located at the middle position near the initial end of the second support base 60141. The initial end of the second support base 60141 is connected to the end of the first conveying table 608. The second pulley 60144 is located at the edge position near the end of the second support base 60141, so that the arrangement directions of the first pulley 60143 and the second pulley 60144 are inclined based on the conveying direction of the paper. A conveying belt 60145 for obliquely conveying the paper is wound around the first pulley 60143 and the second pulley 60144, and the upper half of the conveying belt 60145 is obliquely arranged on the top surface of the support platform 60142. After the first conveying table 608 conveys the paper onto the support platform 60142, the bottom surface of the paper contacts the upper half of the conveying belt 60145. After controlling the conveying belt 60145 to move, the paper can be driven to convey along the inclined direction.

[0110] A positioning rod 60146 for positioning and aligning the paper during the adjustment process is provided at the edge of the second support base 60141 near the second pulley 60144. The length direction of the positioning rod 60146 is parallel to the conveying direction of the paper by the corresponding second conveying module. During the process that the conveying belt 60145 drives the paper to convey along the inclined direction, the paper contacts the positioning rod 60146 one by one. The positioning rod 60146 blocks the side of the paper to achieve unified positioning, realize the position adjustment of the paper, and adjust the paper to be aligned along the length direction of the positioning rod 60146 and arranged in a linear array.

[0111] In addition, a protective plate 601413 for protecting the paper during the adjustment process is provided above the positioning rod 60146; under the action of the protective plate 601413, it is prevented that the paper warps during the adjustment and alignment process, or the paper deforms after contacting the positioning rod 60146 during the conveying process. A third guide rod 60147 with a horizontal axis and perpendicular to the conveying direction of the paper is provided on the second support frame 601, and the second support seat 60141 is slidably arranged horizontally on the third guide rod 60147; by controlling the second support seat 60141 to slide horizontally on the third guide rod 60147, the positions of the conveying belt 60145 and the positioning rod 60146 are adjusted to adapt to papers of different sizes.

[0112] In order to drive the conveying belt 60145 to move, a first spline shaft 60148 with an axis parallel to the axis of the third guide rod 60147 is further provided on the second support frame 601. The second support seat 60141 is rotatably provided with a first transmission gear 60149 and a second transmission gear 601410. The second transmission gear 601410 is coaxially arranged with and fixedly provided with the second pulley 60144 (or the first pulley 60143). The first transmission gear 60149 is coaxially arranged with and slidably provided with the first spline shaft 60148. A first transmission belt 601411 is wound around the first transmission gear 60149 and the second transmission gear 601410. When the first spline shaft 60148 is driven to rotate, the first transmission gear 60149 can be driven to rotate. Moreover, under the transmission action of the first transmission belt 601411 and the second transmission gear 601410, the second pulley 60144 (or the first pulley 60143) is driven to rotate, realizing the driving of the conveying belt 60145. In addition, when the second support seat 60141 slides horizontally on the third guide rod 60147, the first transmission gear 60149 can slide on the first spline shaft 60148. After the position of the first transmission gear 60149 is adjusted, the first spline shaft 60148 can still drive the first transmission gear 60149 to rotate.

[0113] At the end of the second support base 60141, there is a guiding lip plate 601412 (the first alignment conveying part 6014 is connected to the first stacking part 702) for connecting with the first stacking part 702. The guiding lip plate 601412 is used to guide the adjusted paper to the first stacking part 702 for stacking and piling. The protection plate 601413 is equipped with a third fixing frame 601414, and the third fixing frame 601414 is provided with a number of limiting rods 601415 for preventing the paper from separating from the support platform 60142; the limiting rods 601415 are used to limit the paper placed on the support platform 60142. During the process of inclined conveying of the paper, the paper can be accurately conveyed between the protection plate 601413 and the support platform 60142 and contact with the positioning rod 60146.

[0114] As Figure 29 Shown in the figure, the adjusting component includes a fifth rotating shaft 6012 rotatably arranged on the second support frame 601 and having an axis parallel to the axis of the second rotating rod 604. The fifth rotating shaft 6012 is provided with a paper guide plate 6013 for switching the paper conveying direction. The initial state of the paper guide plate 6013 is that its top surface is arranged flatly, and one end of the paper guide plate 6013 close to the paper feeding channel 607 does not contact the top surface of the first conveying table 608. At this time, the second conveying table 6010 and the paper feeding channel 607 are in a disconnected state, and the paper feeding table 603 can convey the paper to the top surface of the first conveying table 608; when it is necessary to switch the conveying direction, control the fifth rotating shaft 6012 to rotate to drive the paper guide plate 6013 to rotate together. When one end of the paper guide plate 6013 close to the paper feeding channel 607 rotates to contact the top surface of the first conveying table 608, the top surface of the paper guide plate 6013 is arranged obliquely. Under the bridging effect of the paper guide plate 6013, the second conveying table 6010 is connected to the paper feeding channel 607, and the first conveying table 608 and the paper feeding channel 607 are in a disconnected state, realizing the switching of the paper conveying direction.

[0115] As Figure 30As shown, the first stacking member 702 includes a clamping and conveying portion 7021 for clamping and conveying the adjusted and aligned paper, and a stacking and conveying table 7023 for supporting the paper stack. It also includes a paper stacking portion 7022 for transporting the paper on the clamping and conveying portion 7021 to the stacking and conveying table 7023 for stacking, and a guiding and limiting portion 7024 for guiding and limiting the paper during the stacking process. The clamping and conveying portion 7021 and the stacking and conveying table 7023 are arranged vertically, and the paper stacking portion 7022 is disposed between the clamping and conveying portion 7021 and the stacking and conveying table 7023. After the first alignment and conveying portion 6014 conveys the adjusted and aligned paper to the clamping and conveying portion 7021, it is received by the clamping and conveying portion 7021. The clamping and conveying portion 7021 clamps and conveys the paper to the paper stacking portion 7022. Subsequently, the paper stacking portion 7022 stacks the paper one by one onto the stacking and conveying table 7023 for palletizing and stacking. And during the stacking process, the stacking and conveying table 7023 moves downward intermittently as the thickness of the paper stack increases. The guiding and limiting portion 7024 guides and limits the paper to keep the paper stack on the stacking and conveying table 7023 neat and prevent the side of the paper stack from deviating and collapsing.

[0116] As Figure 31 shown, the paper stacking portion 7022 includes a rotating shaft 70221 with a horizontal axis and a length direction perpendicular to the paper conveying direction. The rotating shaft 70221 is rotatably arranged on the fixed frame 701, and a number of paper transporting wheels 70222 for transporting the paper to the stacking and conveying table 7023 for stacking are installed on the rotating shaft 70221. A number of second placing grooves 70223 for placing the paper are formed on each paper transporting wheel 70222. The number of second placing grooves 70223 is arranged in an equidistant rotational array around the axis of the rotating shaft 70221. The second placing groove 70223 is arc-shaped. One second placing groove 70223 can place one piece of paper. The rotating shaft 70221 drives a number of paper transporting wheels 70222 to rotate counterclockwise at a constant speed (the rotation direction is based on Figure 31(taking [a certain reference] as the benchmark), when the notch of one of the second placement slots 70223 is aligned with the paper outlet end of the clamping and conveying part 7021, the clamping and conveying part 7021 conveys the paper into the second placement slot 70223. Subsequently, the paper conveying wheel 70222 drives the paper to rotate around the axis of the rotating shaft 70221. After the notch of the next second placement slot 70223 is aligned with the paper outlet end of the clamping and conveying part 7021, the next piece of paper is conveyed into this second placement slot 70223. Operating in this way, the paper can be continuously conveyed. Since the paper is conveyed from top to bottom and the second placement slot 70223 is arc-shaped, when the paper conveying wheel 70222 conveys the paper until it contacts the top of the stacking and conveying platform 7023, the paper conveying wheel 70222 continues to rotate. Under the action of the self-gravity of the paper, the paper automatically disengages from the second placement slot 70223 and is stacked one by one on the stacking and conveying platform 7023 for palletizing and stacking. Moreover, during the palletizing and stacking process, the stacking and conveying platform 7023 moves downward intermittently as the thickness of the paper stack increases to adapt to the change in the thickness of the paper stack.

[0117] As Figure 32 shown, the clamping and conveying part 7021 includes a first mounting frame 70211 installed on the fixed frame 701. The first mounting frame 70211 is provided with a lower clamping part 70212 and an upper clamping part 70213 arranged vertically. The paper is placed between the lower clamping part 70212 and the upper clamping part 70213 to clamp it, and after being clamped, it is conveyed into the second placement slot 70223 on the paper conveying wheel 70222. The lower clamping part 70212 and the upper clamping part 70213 have the same structure and are symmetrically arranged up and down. Among them, the upper clamping part 70213 includes a first support rod 702131 whose axis is parallel to the axis of the rotating shaft 70221. A number of first movable seats 702132 are slidably arranged horizontally 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 the end of the first movable seat 702132 and are arranged along the paper conveying direction. A paper conveying belt 702135 is wound around the third pulley 702133 and the fourth pulley 702134. The lower half of the paper conveying belt 702135 contacts the lower clamping part 70212.

[0118] After 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 up and down, and then the third pulley 702133 or the fourth pulley 702134 is driven to rotate, and the movement of the paper feeding belt 702135 can convey the paper. In order to drive the movement of the paper feeding belt 702135, the upper clamping part 70213 further 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 arranged on the first mounting frame 70211. The second spline shaft 702136 and the third pulleys 702133 on each first movable seat 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 first movable seat 702132 can be driven to rotate simultaneously; in addition, when controlling the first movable seat 702132 to slide horizontally on the first support rod 702131 to adjust the distance between the first movable seats 702132 to adapt to papers of different sizes, during the horizontal sliding process, the third pulleys 702133 slide on the second spline shaft 702136.

[0119] As Figure 33 shown, the stacking and conveying table 7023 includes a second mounting frame 70231 that is movably arranged up and down on the 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. A plurality of second movable seats 70233 for supporting the paper stack are slidably arranged horizontally on the second support rod 70232. A fifth pulley 70234 and a sixth pulley 70235 are rotatably arranged on each second movable seat 70233. The fifth pulley 70234 and the sixth pulley 70235 are respectively placed at the front end and the rear end of the second movable seat 70233 and are 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 conveying wheel 70222 transports the paper to each second movable seat 70233 for stacking. And the bottom of the paper stack contacts the upper half of the support belt 70236. After the paper stacking is completed, the fifth pulley 70234 or the sixth pulley 70235 is driven to rotate, and under the action of the support belt 70236, the paper stack is conveyed to facilitate subsequent stacking processing. In addition, by adjusting the distance between the second movable seats 70233, paper stacks of different sizes can be supported.

[0120] The second mounting frame 70231 is also rotatably provided with a third spline shaft 70237 whose axis is parallel to the axis of the second support rod 70232. The third spline shaft 70237 and the fifth belt pulleys 70234 on each of the second movable seats 70233 are coaxially arranged, and the third spline shaft 70237 and the fifth belt pulleys 70234 are slidably arranged. During the lateral sliding process, the fifth belt pulley 70234 slides on the third spline shaft 70237, and the third spline shaft 70237 can drive the fifth belt pulleys 70234 at different positions.

[0121] As Figure 34 shown, the guiding and limiting portion 7024 includes a mounting frame 70241 installed on the fixed frame 701. The mounting frame 70241 is provided with a left sliding seat 70242 and a right sliding seat 70243 that can slide in directions approaching or separating from each other. The sliding directions of the left sliding seat 70242 and the right sliding seat 70243 are parallel to the axis of the rotating shaft 70221. Among them, a left guiding plate 70244 and a right guiding plate 70245 for guiding the paper during the stacking process are respectively installed on the left sliding seat 70242 and the right sliding seat 70243, and a stacking station 70246 is located between the left guiding plate 70244 and the right guiding plate 70245. The paper transport wheel 70222 rotates to transport the paper to the stacking station 70246 between the left guiding plate 70244 and the right guiding plate 70245, and stacks them one by one on the stacking conveyor table 7023 for palletizing and stacking. During the stacking process, the paper is guided by the left guiding plate 70244 and the right guiding plate 70245, so that the left and right sides of the paper stack remain neat. In addition, by controlling the left sliding seat 70242 and the right sliding seat 70243 to approach or separate from each other, the distance between the left guiding plate 70244 and the right guiding plate 70245 is controlled to adapt to papers of different sizes.

[0122] In this embodiment, a paper blocking rod 70247 and a paper pushing plate 702413 for limiting the paper during the stacking process are respectively arranged on the front and rear sides of the stacking station 70246. There are a pair of third rotating rods 70248 which are respectively fixedly arranged on the left sliding seat 70242 and the right sliding seat 70243. The paper pushing plate 702413 is movably arranged on the mounting frame 70241, and the paper pushing plate 702413 reciprocates in a direction approaching or departing from the stacking station 70246 to push the paper stack into neatness. During the process of palletizing and stacking the paper at the stacking station 70246, the paper pushing plate 702413 reciprocates in a direction approaching or departing from the stacking station 70246, and pushes the paper stack into contact with the paper pushing plate 702413, thereby pushing the front and rear sides of the paper stack to be aligned and making the paper stack neat. The mounting frame 70241 is provided with a reciprocating control mechanism 702414 for controlling the paper pushing plate 702413 to reciprocate in a direction approaching or departing from the stacking station 70246.

[0123] During the guiding process by the left guiding plate 70244 and the right guiding plate 70245, in order to prevent paper jams, the third rotating rod 70248 and the fourth rotating rod 70249 which are arranged vertically and axially parallel to the paper conveying direction are rotatably provided on the left sliding seat 70242 and the right sliding seat 70243 respectively. The third rotating rod 70248 and the fourth rotating rod 70249 are both provided with seventh belt pulleys 702410, and a paper guiding belt 702411 is wound around the vertically arranged seventh belt pulleys 702410; openings 702412 are formed on both the left guiding plate 70244 and the right guiding plate 70245, and the openings 702412 are used for a section of the side of the paper guiding belt 702411 close to the stacking station 70246 to pass through. After the paper guiding belt 702411 on the left sliding seat 70242 passes through the opening 702412, a section of its side close to the stacking station 70246 is flush with the inner side wall of the left guiding plate 70244 or protrudes from the inner side wall of the left guiding plate 70244; similarly, after the paper guiding belt 702411 on the right sliding seat 70243 passes through the opening 702412, a section of its side close to the stacking station 70246 is flush with the inner side wall of the right guiding plate 70245 or protrudes from the inner side wall of the right guiding plate 70245. During the process of guiding the paper by the left guiding plate 70244 and the right guiding plate 70245, the left and right sides of the paper are respectively in contact with the surfaces of different paper guiding belts 702411. After driving the paper guiding belts 702411 on the left and right sides to move towards the stacking station 70246, a downward force can be applied to the paper, improving the guiding effect and preventing paper jams.

[0124] In summary, it can be seen that the present invention has the excellent characteristics described above, enabling it to enhance the efficiency that has never existed in the prior art during use and having practicality, thus becoming a product with extremely high practical value.
