[0002] Based on actual market demand and customer working conditions, sheet-fed bundling machines can replace manual bundling, freeing workers from heavy, repetitive labor. Compared to manual labor, they offer higher bundling efficiency, significantly reducing packaging costs for printing companies. Furthermore, since the vast majority of printing companies in China now use sheet-fed packaging, sheet-fed bundling machines meet customer needs and are more readily accepted. Moreover, the frame structure of sheet-fed bundling machines not only meets customers' needs for convenient transportation and handling but also minimizes floor space requirements. Finally, sheet-fed packaging and bundling machines can be used both standalone and in production lines, connecting to high-speed perfect binding lines and robotic arms to meet the automation and intelligent improvement needs of post-press processes. Summary of the Invention

[0042] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0043] This invention relates to a single-sheet paper packaging and bundling machine, such as... Figure 1 As shown, the equipment includes a feeding mechanism 1, a gripping mechanism 2, a paper feeding mechanism 3, a paper pulling mechanism 4, a trolley unit 5, a transition mechanism 6, and a frame 7. The frame 7 is used to support and connect the remaining structures except for the paper feeding mechanism 3. The integrated design of the frame 7 facilitates the hoisting and transportation of the equipment.

[0044] like Figure 2 As shown, the feeding mechanism 1 includes a first-stage feeding mechanism 8, a second-stage feeding mechanism 9, and a third-stage feeding mechanism 10. When used online, the first-stage feeding mechanism 8 and the second-stage feeding mechanism 9 will be reduced or modified according to the actual application scenario. Among them, the third-stage feeding mechanism 10 has a book-supporting mechanism 12 and a book-pushing mechanism 11 in sequence.

[0045] like Figure 3 As shown, the book-supporting mechanism 12 includes a vertical plate 40, a support rod 24 connected to the vertical plate 40, a plate 41 connected to the vertical plate 40, and the plate 41 is fixed to the three-section feeding mechanism 10 by a bracket 42.

[0046] like Figure 4 As shown, the left and right side baffles 14 of the book pushing mechanism 11 are connected to the left and right side guide cylinders 13 extending from the guide rod side. At the same time, the positioning plate 15 is connected to the guide rod extending side of the three-axis cylinder 16. The three-axis cylinder 16 is associated with the slide rail 39 through the fixing plate 38. The left and right slide rails 39 are respectively connected to the left and right profiles of the three-section feeding mechanism 10.

[0047] The working principle of feeding mechanism 1 is as follows: When using a single machine, a single package of books is placed into the first feeding mechanism 8, and then handed over to the third feeding mechanism 10 by the second feeding mechanism 9. The main function of the book pushing mechanism 11 is to tidy up loose and unpacked single packages of books. The main working principle of the book pushing mechanism 11 is as follows: Initially, the left and right baffles 14 are closed, preventing the single package of books from moving forward. When the conditions for two stacks of single packages of books to arrive are met, the left and right guide cylinders 13 drive the left and right baffles 14 to open to both sides, and the two stacks of single packages of books continue to move forward to the positioning plate 15. At this time, the left and right guide cylinders 13 also return the left and right baffles 14 to their original positions, presenting a closed mode. At the same time, the three-axis cylinder 16 drives the positioning plate 15 to push the two stacks of single packages of books back to the left and right baffles 14 in the opposite direction, giving a certain impact force to tidy up the loose and unpacked books. The positioning plate 15 returns to its position to perform a positioning function, and the two stacks of neatly packed single packages of books also reach the position of the positioning plate 15, preparing for the next cycle.

[0048] like Figure 5 As shown, the gripping mechanism mainly consists of a moving unit 17 and a book gripping unit 18;

[0049] like Figure 6 As shown, the frame 7 is welded from a steel frame and is generally divided into three layers: bottom frame 21, middle frame 22, and upper frame 23. The packaging paper is single-sheet kraft paper. The fixed frame 36 is directly connected to the upper frame 23. The left and right guide cylinders 13 are connected to the fixed frame 36 through cylinder brackets 37.

[0050] The main function of the feeding mechanism 1 is to supply the packaged individual books and periodicals to the designated location, completing the feeding process in the large packaging process.

[0051] The main functions of the paper feeding mechanism 3 and the paper pulling mechanism 4 are to place single sheets of paper packaging paper into predetermined positions to complete the paper feeding process.

[0052] The gripping mechanism 2 mainly grips the books and periodicals from the predetermined positions of the three-section feeding mechanism and places them onto the predetermined positions on the packaging paper of the paper pulling mechanism 4. The trolley unit 5 and the gradient unit 6 mainly complete the book and periodical packaging and shaping function.

[0053] like Figure 7 As shown, the trolley unit 5 consists of a sinking mechanism 31, an upward pushing mechanism 32, a trolley traveling mechanism 33, a paper supporting mechanism 34, and a set of side pushing mechanisms 35.

[0054] like Figure 8 As shown, the structure of the paper feeding mechanism 3 is as follows: it includes a frame 43, which is the overall foundation and fixed frame of the paper feeding mechanism 3. The bearing support A51 is fixed by the support connector 50. The two ends of the drive shaft A56 are coaxially sleeved with the bearing support A51. The reducer 28 is coaxially sleeved with the drive shaft A56. The left and right double-row shaft chains 49 are coaxially sleeved with the two ends of the drive shaft A56. The sprocket A48 is coaxially sleeved with the pin and fixed on the frame 43. The lower end of the chain connector 44 is connected to the upper end of the left and right adjustment component 25 (one end of the left and right adjustment component 25 is equipped with a limit switch A52, and one end of the roller 54 is equipped with a limit switch B53). The upper end of the chain connector 44 matches and engages with one end of the chain 27. The other end of the chain 27 goes upward through the engaging sprocket 48 and the double-row shaft chains 49, and then goes vertically downward from the other side by a steel wire rope connected to and passing around the frame. The lower pulley of 43 is connected to the side of the chain connector 44. Thus, the left and right adjustment component 25 can move up and down through the action of the reducer 28, thereby realizing the function of feeding kraft paper. The left and right ends of the horizontal support 45 are fixed to the frame 43. One end of the cylinder connecting plate 47 is connected to the cylinder A46, and the other end of the cylinder connecting plate 47 is fixed to the horizontal support 45. The extended end of the cylinder A46 is connected to the nozzle connecting plate 71, thus realizing the up and down movement of the nozzle component 26 controlled by the cylinder A46. The two ends of the roller 54 are fixed to both sides of the frame 43. The hole on the short shaft 55 is coaxially sleeved on the long rod 61. It can be moved up and down along the long rod 61 by the handle 73. Because the kraft paper may curl at the edges, in order to allow the nozzle component to suck air smoothly, the roller 54 and the short shaft 55 play the role of pressing the edge of the kraft paper.

[0055] like Figure 9 , 10As shown, the paper pulling mechanism 4 has the following structure: it includes a large plate 72, which is fixed to the intermediate frame 22; left and right linear guide rails 59 are fixed to both sides of the large plate 72; clamping plates 30 are fixed to the sliders of the left and right linear guide rails 59; clamps 29 are fixed to the predetermined positions on clamping plates 30; long shaft supports A68 on the left and right sides are coaxially sleeved on both ends of long shaft 60; long shaft supports B69 on the opposite side are coaxially sleeved on both ends of long shaft 60; pulleys A58 are coaxially sleeved on both ends of long shaft 60 and both ends of transmission shaft A56; synchronous belt A57 is synchronously meshed with pulleys A58; the open end of synchronous belt A57 is fixed to clamping plate 30; the shaft end of motor A63 coaxially passes through one end hole of motor connecting block 74 and is coaxially sleeved with pulley B62; the other end of motor connecting block 74 is fixed to frame 43; and the pulleys on long shaft 60... A58 and pulley B62 are synchronously engaged by a synchronous belt. Motor A63 then drives clamp 29 to move back and forth, pulling the kraft paper to the predetermined position of the paper-pulling mechanism. Four brush cylinders 65 are fixed to frame 43 via connectors 64. Brushes 70 are installed at the extended ends of brush cylinders 65, enabling the brushes 70 to move up and down. After clamp 29 pulls a section of a single sheet of kraft paper from one end of the paper-pulling mechanism to the other, the sheet of kraft paper is laid flat on the large plate 72. The extended ends of brush cylinders 65 extend, and brushes 70 press against the single sheet of kraft paper, preventing it from rolling up or becoming misaligned. Tensioning support 66 and tensioning block 67 are fixed to frame 43. The lower end of long shaft support A68 is fixed to tensioning block 67, and adjusting bolts adjust the tension of synchronous belt A57.

[0056] like Figure 11 As shown, the structure of the left and right adjustment assembly is as follows: it includes a bearing support B79 installed on the left and right adjustment frame 76, which is the basic frame; a linear guide rail 77 is fixed on the bearing support B79 and connected to the slide plate 82; a lead screw support plate 75 is connected to the bottom of the slide plate 82; a lead screw B83 is coaxially sleeved with the center hole of the lead screw connector 78 and sequentially coaxially sleeved with the left bearing support B79 and one end of the coupling A84; and a light shaft 80 is sequentially coaxially sleeved with the right bearing support B79 and the center hole of the handwheel 81. Thus, the kraft paper on the slide plate 82 can be adjusted left and right by adjusting the handwheel 81.

[0057] The main function of the paper pulling mechanism 4 and the paper feeding mechanism 3 is to supply materials for single-sheet kraft paper packaging. When the left-right adjusting component 25 is lowered to its lowest position, a stack of kraft paper packaging is placed on it. Then, the left-right adjusting component 25 is raised to the allowable position of the limit switch A52. The cylinder A46, through the nozzle connecting plate 71, lowers the nozzle assembly 26 to a predetermined position, holding the top single sheet of kraft paper in place. The cylinder A46 then lifts one side of the single sheet of kraft paper on the nozzle assembly 26 through the nozzle connecting plate 71, separating it. After the clamp 29 connects with the single sheet of kraft paper on the nozzle assembly 26, it moves to the other side of the paper pulling mechanism 4 under the combined action of the linear guide rail 59 and the synchronous belt A57, thus laying the single sheet of kraft paper flat on the predetermined position of the large plate 72 in the paper pulling mechanism 4. These steps are repeated to complete the supply of materials for single-sheet kraft paper packaging.

[0058] The gradient mechanism 6 mainly consists of a side plate adjustment assembly, a height adjustment assembly, and a roller conveyor line. As the semi-formed book 98 moves forward with the gradient roller conveyor line, the side plate adjustment assembly can adjust the opening and closing size according to the book specifications, and the height adjustment assembly can adjust the height position according to the book specifications.

[0059] like Figure 12 , 13 As shown, the left and right sides of the side panel adjustment assembly are symmetrical, and the explanation is based on one side. The side panel adjustment assembly includes a base plate 92, which is fixed to the bottom frame 21. The upper end of the fixed bend 89 is connected to the fixed plate 85, and the lower end of the fixed bend 89 is fixed to the base plate 92. Flange bearings 96 are fixed to the four corners of the fixed plate 85, and guide shaft supports 97 are fixed to the four corners of the adjustment base plate 86. The guide shaft 95 is coaxially sleeved with the flange bearings 96 and the guide shaft supports 97. One end of the connecting block A93 and the connecting block B94 is fixed to the adjustment base plate 86, and the other end is connected to the side gradient pressure plate 88, the side pressure plate 87, the side guard 90, and the side top gradient pressure plate 100. The side strip 91 is fixed to... On the flange 90, the motor C99 is fixed on the fixing plate 85. The lead screw end of the motor C99 extends from the center hole of the fixing plate 85. The lead screw nut assembly 101 is fixed on the adjusting base plate 86. The lead screw end of the motor C99 is coaxially sleeved with the center hole of the lead screw nut assembly 101 and extends from the center hole of the adjusting base plate 86. Thus, under the power of the motor C99, the opening and closing distance between the two side gradient pressure plates 88, the side pressure plate 87, and the flange 90 can be adjusted. The guide patch 102 is fixed on the inlet side of the side gradient pressure plate 88. The semi-formed book 98 is located between the guide patch 102 and the side upper gradient pressure plate 100.

[0060] like Figure 14 , 15As shown: The height adjustment assembly includes a floating plate 124, which is fixed to the intermediate frame 22. Flange bearings 126 are respectively installed at the four corners of the floating plate 124. Shaft supports 123 are installed on the track floating plate 133.

[0065] like Figure 20 , 21 As shown, the paper-supporting mechanism 34 has the following structure: it includes two parallel long plates 177, which are connected to the base plate 135 via linear guides. The long plates 177 are sliding sides. A shaft block 178 is installed at one end of each of the two long plates 177. A long shaft A179 is installed horizontally between the two shaft blocks 178. A bearing is provided at the connection between the long shaft A179 and the shaft block 178. A cylinder E1 is installed on one side of one of the base plates 135 via a pad 185. 83. Cylinder E183 is arranged parallel to the long plate 177; the cylinder body of cylinder E183 is fixed on the pad 185, the piston rod end of cylinder E183 is connected to one end of swing rod 184, the other end of swing rod 184 is connected to long shaft A179, the two ends of long shaft A179 are also connected to one end of two shaft connecting rods 181 respectively, the other ends of the two shaft connecting rods 181 are respectively connected to the two ends of pressure rod 180; each long plate 177 is also provided with a limit shaft 182.

[0066] like Figure 22As shown, the moving unit 17 includes a pad I185, which is mounted on the upper part of the upper frame 23. The slider E187 and the pad I185 are associated through a long linear guide rail 189, which is mounted on the guide rail base 186. The slider E187 is the sliding side. The bracket II188 is fixed on the lower surface of the slider E187. The linear guide rail B190 is fixed inside the bracket II188 through the pad. The lead screw B195 is mounted inside the bracket II188 using a conventional lead screw support. The synchronous pulleys I 193 and II 194 are fitted with synchronous belts. The lifting motor 191 provides power. The pulleys III 196 and IV 197 are fitted with synchronous belts. The reduction motor B192 provides power.

[0067] like Figure 23 As shown, the basic structure of the book gripping unit 18 is as follows: The entire book gripping unit 18 is connected to the linear guide rail B190 slider via the bent plate B204 and the pad II205, and then fixed to the moving unit 17 structure. The bent plate B204 and the pad II205 are respectively installed on the upper and lower sides of the plate E198. The bracket D199 and the slider F201 are both installed on the lower surface of the plate E198. The left and right guide rail brackets B200 are assembled by connecting them to the bracket D199 and the slider F201 with screws. The left and right claws... A202 is connected to the guide rail bracket B200 via the linear guide rail E206. The left and right claws A202 are sliding sides. The power to drive the linear guide rail E206 is provided by the left and right cylinders M207 and the motor H208 (motor H208 is mounted on the motor bracket B203). The pulleys I209 and II210 are connected by a synchronous belt to transmit power, driving the lead screw IV212 to rotate, which in turn drives the slider of the linear guide rail C212 to slide, thereby driving the opening and closing of the right half of the book gripping unit 18 mechanism.

[0068] The basic working principle of the gripping mechanism is as follows: The geared motor B192 provides power, utilizing the synchronous belt structure of pulleys III196 and IV197 connected to the synchronous belt, causing the slider E187 to move the entire book-gripping unit 18 to the left to the predetermined book-gripping position. Motor H208 provides power, utilizing the synchronous belt structure of pulleys 209 and II210 connected to the synchronous belt, which in turn drives the lead screw 211 to rotate. This, in turn, causes the slider of the linear guide C212 to open and close the gripper on the right side of the book-gripping unit 18, adjusting it to the appropriate opening and closing length for gripping the book. The lifting motor 191 provides power, utilizing the synchronous belt structure of pulleys I193 and II197 connected to the synchronous belt... The synchronous belt structure of 194 works as follows: the lead screw B195 rotates, and the linear guide rail B190 slider drives the book gripping unit 18, whose gripper opening and closing degree has been adjusted, to descend to the predetermined position for placing the book on the three-section feeding mechanism 10. Similarly, the book gripping opening and closing length is reduced until the grippers 202 on both sides can grab the book from the bottom. 191 provides power, and the entire gripper unit 18, along with the book, moves upward to a height where there is no interference in the horizontal direction. Then, the geared motor B192 provides power, and the whole unit moves to the right to the predetermined position for placing the book on the paper pulling mechanism. The book gripping unit 18, which is holding the book, moves downward as a whole, and the claws on both sides 202 open, placing the book on the predetermined position on the single sheet of paper laid flat on the paper pulling mechanism 4.

[0069] The basic working principle of the trolley unit 5 is as follows: the extension end of the sinking cylinder 139 extends, the sinking support plate 134 rises, and the book is placed in the predetermined position on the paper pulling mechanism 4. The extension and retraction of the extension end of the sinking cylinder 139 causes the sinking support plate 134 to drive the single sheet of paper and the book to descend. After the paper and the book descend, the extension end of the cylinder E183 in the paper supporting mechanism 34 extends, thereby adjusting the angle of the long shaft 179 and the swing rod 184, thereby adjusting the angle of the pressure rod 180 and the shaft connecting rod 181, so that the pressure rod 180 can press down the front side of the book wrapped with the single sheet of paper, which can prevent the single sheet of paper from sliding down and the book from tilting forward. In the side pushing mechanisms 35 on both sides, the motor provides power. The opening and closing size of the side pushing mechanisms 35 on both sides is adjusted according to the total width of the two stacks of books. The extension end of the cylinder IV174 retracts, causing the book pushing side plate 170 to drive the corner plate II. 173 extends to both sides of the two stacks of books; motor C176 provides power, causing the book-pushing side plate 170 to drive the corner plate I 172 to rise to the height of the books, and the cylinder D175 extends its extension end, driving the corner plate I... 172 Fold the back two sides of the single-sheet wrapping paper inward along the top rear side of the book; the motor V165 in the push mechanism 32 provides power to adjust the upper folding plate 157 to the height position of the book, and the cylinder 213 extends and retracts, which determines the extension and retraction of the upper folding plate 157. When the upper folding plate 157 extends, the back side of the single-sheet wrapping paper is folded along the top surface of the book, completing all the above steps, and the back side of the book is basically finished with the packaging action; the coupling connected to the extension end of the cylinder 214 is coaxially sleeved with the guide shaft I141 in the sinking mechanism 31. The retraction of the cylinder 214 causes the entire trolley traveling mechanism 33 to move forward, and then the discharge cylinder 151 extends, pushing out the upright plate 149 to push the half-packaged book and single-sheet wrapping paper to the gradient mechanism 6 to complete the remaining packaging.

[0070] The working principle of the single-sheet paper packaging and bundling machine of the present invention is as follows: a single package of books and periodicals passes through a first-stage feeding mechanism 8 and a second-stage feeding mechanism 9, and then enters a third-stage feeding mechanism 10. The book pushing mechanism 11 then aligns the loose books and periodicals. After aligning the books, the positioning plate 15 positions the gripping position for the double stack of books and periodicals. The support rod 24 in the book-supporting mechanism 12 is located between the transport rollers of the third-stage feeding mechanism to prevent the bottom layer of thin books and periodicals from getting stuck between the rollers during transport, thus affecting the gripping of the gripping mechanism 2. A stack of kraft paper placed on the left and right adjustment components 25 by the paper feeding mechanism 3 is sucked up by the suction nozzle component 26, and then the clamp 29 in the paper pulling mechanism 4 transfers the sucked-up kraft paper to the predetermined position along with the clamp plate 30. The moving unit 1... 7 drives the book-grabbing unit 18, which uses claws 20 to grab the two stacks of single-packaged books and periodicals at the predetermined positions of the three-section feeding mechanism 10 and transport them to the predetermined positions of the single kraft paper in the paper-pulling mechanism 4; the sinking mechanism 31 rises up to sink the two stacks of single-packaged books and periodicals on the kraft paper in the paper-pulling mechanism to the predetermined positions of the trolley unit 5. The pushing mechanism 32 and a set of side-pushing mechanisms 35 complete the double-sided half-packaging and top packaging of the large package. The paper-supporting mechanism 34 can provide support for the front of the packaging paper and prevent the books and periodicals from tilting forward during the sinking of the kraft paper. Then, the trolley traveling mechanism 33 hands over the half-packaged books and periodicals to the gradient mechanism 6; the gradient mechanism 4 completes the remaining packaging and plays a certain shaping role, and finally hands it over to the bundling machine to complete the crisscross bundling.
