Description

Technical Field

[0001] This invention relates to the technical field of packaging box production, and more specifically to an automated packaging box production system. Background Technology

[0002] Packaging boxes typically consist of a lid and a base that fit together. Both the lid and base are semi-box-shaped components made up of an inner box and wrapping paper. The inner box includes a rectangular base and two long side panels and two short side panels perpendicular to the edge of the base, forming a rectangular box structure enclosed by the base, the two long side panels, and the two short side panels. The structure of the wrapping paper when laid flat is similar to [the previous description]. Figure 1 As shown, it includes a bottom surface 1, two long side surfaces 2, two long bent surfaces 3, two short side surfaces 4, and two short bent surfaces 5. The two sides of the long side surfaces 2 are integrally formed with ears 6. The dimensions of the bottom surface 1 of the packaging paper match the dimensions of the bottom plate of the inner box, the dimensions of the long side surfaces 2 of the packaging paper match the dimensions of the long side plates of the inner box, and the dimensions of the short side surfaces 4 of the packaging paper match the dimensions of the short side plates of the inner box.

[0003] When assembling the half-box, the operator needs to glue and fix the bottom surface 1 of the packaging paper to the bottom of the inner box base plate, fold the two long side surfaces 2 upwards, and glue and fix the long side surfaces 2 to the outer wall of the long side plate. Then, fold the long bent surface 3 downwards and glue and fix the long bent surface 3 to the inner wall of the long side plate. Then, fold the support lug 6 and glue and fix it to the outer wall of the short side plate. Then, fold the short side surface 4 upwards and glue and fix the short side surface 4 to the outer wall of the short side plate. Then, fold the short bent surface 5 downwards and glue and fix the short bent surface 5 to the inner wall of the short side plate. This completes the assembly of the half-box. However, this manual operation method is labor-intensive and inefficient in mass production. Summary of the Invention

[0004] The present invention aims to provide an automated production system for packaging boxes, which can realize the automated mass production of half-box components, thereby saving manpower and improving production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: 1) An automated production system for packaging boxes, comprising a gluing section, a box-setting section and a forming section arranged sequentially along the conveying direction, wherein the gluing section includes a feeding structure and a coating structure arranged sequentially along the conveying direction, the coating structure being a glue machine for applying glue to the upper surface of the packaging paper, and the feeding structure being used to feed the packaging paper sheet by sheet to the glue machine. The box-setting section includes a first conveyor with a conveyor belt. The feed end of the first conveyor is connected to the discharge end of the glue machine. The first conveyor is equipped with an inner box placement structure and a pressing structure along the conveying direction. The inner box placement structure is used to place the inner box on the packaging paper so that the bottom of the inner box is bonded to the bottom surface of the packaging paper. The pressing structure is used to press the inner box and the packaging paper together to obtain the folded part. The forming section includes a folding structure and a shaping structure arranged sequentially along the conveying direction. The folding structure is connected to the discharge end of the first conveyor. A second conveyor with a conveyor belt is connected between the folding structure and the shaping structure. The folding structure is used to fold the part to be folded so that the packaging paper and the inner box are completely bonded to obtain a half-box part. The shaping structure is used to press and shape the half-box part.

[0006] In this invention, the feeding structure of the gluing section first continuously feeds packaging paper to the glue machine. After the glue machine completes the gluing operation on the upper surface of the packaging paper, the glued packaging paper moves from the discharge end of the glue machine to the first conveyor connected to it. It moves towards the folding structure with the conveyor belt of the first conveyor. During the process of the packaging paper moving towards the folding structure, the packaging paper passes through the inner box placement structure and the pressing structure in sequence. The inner box placement structure places the inner box on the packaging paper to initially bond the bottom of the inner box to the bottom surface of the packaging paper. Then, the pressing structure presses the inner box and the packaging paper to strengthen the bond between them, resulting in a folding part composed of the inner box and the packaging paper.

[0007] Subsequently, the folding piece continues to move towards the folding structure along the conveyor belt of the first conveyor. After the folding piece enters the folding structure, the folding structure folds the packaging paper of the folding piece, so that each part of the packaging paper is completely bonded to the corresponding part of the inner box, thus forming a half-box. Then, the formed half-box enters the second conveyor connected to the discharge end of the folding structure and moves towards the shaping structure along the conveyor belt of the second conveyor. After the half-box enters the shaping structure, the shaping structure presses and shapes the half-box, improving the adhesion between the packaging paper and the inner box, thus completing the production of the half-box.

[0008] In summary, the above methods can achieve automated mass production of semi-box-shaped parts, thereby saving manpower and improving production efficiency.

[0009] 2) An automated packaging box production system according to 1), wherein: The glue machine has a feeding platform at the feeding end. The feeding structure includes a worktable located on the side of the glue machine's feeding platform. The worktable is used to stack and place packaging paper. A first support and a second support are sequentially mounted above the worktable along the transport direction. A first gripper is provided on the first support, which can move horizontally back and forth between the worktable and the feeding platform and can be raised and lowered. The first gripper is used to grip the packaging paper and transfer it to the feeding platform. A first motor is installed on one side of the second bracket. A rotating rod is fixedly connected to the output end of the first motor. The rotating rod is rotatably connected to the other side of the second bracket. Two support blocks are fixedly connected to the rotating rod. A roller is inserted between the two support blocks and rotatably connected. A second motor is fixedly connected to the side of any support block away from the other support block. The output end of the second motor is fixedly connected to the end of the roller. A roller wheel is fixedly connected to the roller. The side of the roller wheel can abut against the top of the feeding platform.

[0010] In this invention, before production starts, the operator stacks multiple sheets of packaging paper on the workbench to form a stack, the first gripper is suspended above the stack, and the roller is suspended above the feeding table. After production starts, the first gripper moves downward to grab a single sheet of packaging paper, then lifts up and moves towards the feeding table to transfer the packaging paper to the feeding table so that the packaging paper is located below the roller; After the packaging paper is in place, the first motor drives the rotating rod to rotate, causing the two blocks to swing downwards synchronously. The roller shaft, roller wheel, and second motor swing downwards synchronously with the blocks until the roller wheel comes into contact with the packaging paper on the feeding table. At this time, the first motor stops running, the first gripper releases the packaging paper and moves back to its original position, the second motor starts and drives the roller shaft to rotate, causing the roller wheel to rotate. The packaging paper is fed into the glue machine by the friction between the roller wheel and the packaging paper, and the glue machine applies glue to the upper surface of the packaging paper. Once the current packaging paper is fed, the second motor stops running, and the first motor drives the rotating rod to rotate and reset, which in turn drives the support block, roller shaft and roller wheel to swing back to their original positions. This completes the feeding of a single sheet of packaging paper. By repeating the above process, packaging paper can be continuously fed to the glue machine, which then continuously applies glue to the packaging paper, thus achieving automated feeding and gluing, saving manpower and improving production efficiency.

[0011] 3) An automated packaging box production system according to 1), wherein: The inner box placement structure includes an inner box conveyor located on one side of the first conveyor. The inner box conveyor is used to transport the inner box towards the first conveyor. A third support is provided above the inner box conveyor. A second gripper is provided on the third support, which can move horizontally back and forth between the first conveyor and the inner box conveyor and can be raised and lowered. The second gripper is used to grip the inner box and transfer it to the top of the packaging paper.

[0012] 4) An automated packaging box production system according to 1), wherein: The pressing structure includes a fourth support mounted above the first conveyor, and a first pressure plate that can be raised and lowered is provided on the fourth support. The first pressure plate is used to press the inner box and the packaging paper together to form the folded part.

[0013] In this invention, in the initial state, the second gripper is suspended above the inner box conveyor, and the first pressure plate is suspended above the first conveyor. The first conveyor continuously transports the glued packaging paper towards the folding structure, so that the glued packaging paper passes through the inner box conveyor and the first pressure plate in sequence. When the glued packaging paper moves to the position corresponding to the inner box conveyor, the first conveyor stops running, the second gripper moves downward to grip the inner box, then lifts it and moves it towards the first conveyor, moving the inner box to the bottom surface of the packaging paper, and then lowers it until the bottom of the inner box is attached to the bottom surface of the packaging paper, so that the bottom of the inner box is initially bonded to the bottom surface of the packaging paper. Then the second gripper is lifted and reset above the inner box conveyor, and the first conveyor resumes operation.

[0014] When the packaging paper with the inner box attached moves along the conveyor belt of the first conveyor to the area below the first pressure plate, the first conveyor stops running again. The first pressure plate moves downward to abut against the top of the inner box, applying pressure to the inner box and the packaging paper, pressing them together to strengthen the bond between them, thus producing a foldable part composed of an inner box and packaging paper. Then the first pressure plate is raised and reset, and the first conveyor resumes operation. By repeating the above process, foldable parts can be produced continuously, thereby realizing automated mass production of foldable parts, saving manpower and improving production efficiency.

[0015] 5) An automated production system for packaging boxes according to 1), wherein: The folding structure includes a fifth support located between the first conveyor and the second conveyor. The fifth support is provided with a long side folding unit, a support ear folding unit and a short side folding unit from top to bottom. The long side folding unit is used to fold the long side and long curved surface of the packaging paper to bond it to the corresponding part of the inner box. The support ear folding unit is used to fold the support ear of the packaging paper to bond it to the corresponding part of the inner box. The short side folding unit is used to fold the short side and short curved surface of the packaging paper to bond it to the corresponding part of the inner box. The fifth support is also provided with a liftable lifting plate. The lifting plate has a long rectangular structure that matches the bottom surface size of the packaging paper. During the lifting process, the lifting plate can pass through the long side folding unit, the support ear folding unit and the short side folding unit in sequence. A sixth support is mounted above the fifth support. The sixth support is equipped with a second pressure plate that can be raised and lowered. The second pressure plate can simultaneously abut against the inner bottom surface of the inner box and the four inner side walls. The sixth support is also equipped with a folding gripping unit, which is used to transfer the part to be folded to the lifting plate and to transfer the half-box part to the second conveyor.

[0016] 6) An automated production system for packaging boxes according to 5), wherein: The long side folding unit includes two long side folding pieces arranged opposite each other on the fifth bracket. The two long side folding pieces are arranged along the width direction of the lifting plate. Each long side folding piece includes a first fixing strip, a first push piece, and a first push plate arranged sequentially from top to bottom on the fifth bracket. The first fixing strip, the first push piece, and the first push plate can all reciprocate along the width direction of the lifting plate. The first fixing strip, the first push piece, and the first push plate are in contact with each other in sequence. The opposite side of the two first fixing strips is arc-shaped, and the opposite side of the two first push plates can respectively abut against the two long sides of the lifting plate. The folding lug unit includes two folding lugs arranged opposite each other on the fifth bracket. The two folding lugs are arranged along the width direction of the lifting plate. Each folding lug includes a moving rod that can reciprocate along the width direction of the lifting plate. Two folding blocks are fixedly connected to the moving rod. The opposing sides of the two folding blocks can respectively abut against the two short sides of the lifting plate. The short-side folding unit includes two short-side folding components arranged opposite each other on the fifth bracket. The two short-side folding components are arranged along the length of the lifting plate. Each short-side folding component includes a second fixing strip, a second push plate, and a second push plate arranged sequentially from top to bottom on the fifth bracket. The second fixing strip, the second push plate, and the second push plate can all reciprocate along the length of the lifting plate. The second fixing strip, the second push plate, and the second push plate are in sequential contact with each other. The opposite side of the two second fixing strips is arc-shaped, and the opposite side of the two second push plates can respectively abut against the two short sides of the lifting plate.

[0017] In this invention, when the piece to be folded moves to the discharge end of the first conveyor along with the conveyor belt, the first conveyor pauses operation. The folding gripping unit grips the piece to be folded and transfers it to the lifting plate, aligning the bottom surface of the packaging paper in the piece to be folded with the top of the lifting plate. The second pressure plate descends and extends into the inner box of the piece to be folded, abutting against the inner wall of the inner box, clamping the piece to be folded between the lifting plate and the second pressure plate. Subsequently, the lifting plate and the second pressure plate descend, causing the piece to be folded to move downwards, sequentially passing through the long side folding unit, the lug folding unit, and the short side folding unit. At the same time, the first conveyor resumes operation until the next piece to be folded moves to its discharge end, at which point the first conveyor pauses operation again.

[0018] During the downward movement of the part to be folded, the specific operation modes of the lifting plate, the second pressure plate, the long side folding unit, the support lug folding unit, and the short side folding unit are as follows: (1) Before the folded part descends to the long side folding unit, the two first fixing bars in the long side folding unit move towards each other along the width direction of the lifting plate until the distance between the two first fixing bars is just enough for the lifting plate to pass through. Since the size of the lifting plate matches the bottom surface of the packaging paper, and the bottom surface of the packaging paper in the folded part is aligned with the top of the lifting plate, both the short and long sides of the packaging paper in the folded part extend out of the lifting plate. Since the distance between the two first fixing strips is just enough for the lifting plate to pass through, as the folded part continues to descend and pass through the first fixing strip, the long side of the packaging paper in the folded part is blocked by the arc surface of the first fixing strip and folds upward toward the outer wall of the long side plate of the inner box in the folded part. When the item to be folded descends to the top of its inner box and is level with the top of the first push plate, the lifting plate and the second pressure plate stop moving, the first fixing bar moves back to its original position, and the two first push plates move towards each other until they abut against the long side of the lifting plate, pressing the long side of the packaging paper against the outer wall of the long side plate of the inner box to make them stick together. Then the second pressure plate moves upward to detach from the piece to be folded, and the two first push plates move towards each other along the width of the lifting plate. Since the top of the inner box is flush with the top of the first push plate at this time, the long bending surface of the packaging paper folds upward along the long side and extends upward out of the first push plate. Since the top of the first push plate is in contact with the top of the first push plate, the first push plate can push the long bending surface to fold towards the middle of the inner box, so that the long bending surface is perpendicular to the long side plate of the inner box. Then the first push plate resets, and the second pressure plate moves downward to push the long folded surface downward until the second pressure plate is completely against the inner wall of the inner box. At this time, the long side of the packaging paper, the long side plate of the inner box, and the long folded surface of the packaging paper are held between the second pressure plate and the first push plate. The second pressure plate and the first push plate jointly apply pressure to the three, completing the adhesion between the long side of the packaging paper and the outer wall of the long side plate of the inner box, and the adhesion between the long folded surface of the packaging paper and the inner wall of the long side plate of the inner box. Then the first push plate resets, and the second pressure plate and the lifting plate together drive the part to be folded to continue to descend.

[0019] (2) After the long side of the packaging paper is folded upward and glued to the outer wall of the long side plate of the inner box, the tabs on both sides of the long side are folded upward to be perpendicular to the short side plate of the inner box and extend out of the lifting plate. When the piece to be folded descends to the tab folding unit, the lifting plate and the second pressure plate stop moving. The two moving rods move towards each other along the length of the lifting plate, driving the folding block to push the tabs of the packaging paper to fold to the outer wall of the short side plate of the inner box, and finally glue the tabs to the outer wall of the short side plate of the inner box. Then the folding block is reset, and the second pressure plate and the lifting plate together drive the piece to be folded to continue to descend.

[0020] (3) Referring to the operation mode of the lifting plate, the second pressure plate and the long side folding unit in (2), the operation mode of the second fixing strip, the second push piece and the second push plate in the short side folding unit corresponds one-to-one with the operation mode of the first fixing strip, the first push piece and the first push plate in the long side folding unit. Finally, the short side of the packaging paper is bonded to the outer wall of the short side plate of the inner box, and the short folded surface of the packaging paper is bonded to the inner wall of the short side plate of the inner box, so as to obtain the bonded half box part.

[0021] Subsequently, the lifting plate and pressure plate rise and reset. While the folding gripping unit transfers the folded half-box part from the lifting plate to the second conveyor, it also transfers the next part to be folded to the lifting plate. By repeating the above process, half-box parts can be produced continuously, thereby realizing the automated mass production of half-box parts, saving manpower and improving production efficiency.

[0022] 7) An automated production system for packaging boxes according to 6), wherein: The height of the first conveyor belt is the same as the height of the second conveyor belt. The folding gripping unit includes a first movable frame that can reciprocate along the arrangement direction of the first conveyor, the lifting plate, and the second conveyor. The bottom of the first movable frame is provided with four clamping blocks. The clamping blocks can move toward or away from the center of the first movable frame. The clamping blocks have clamping grooves on their sides. The four clamping grooves can simultaneously abut against the upper half of the four corners of the inner box. The side of the first movable frame facing the second conveyor is provided with two first clamping plates that can move toward or away from each other. The side of the two first clamping plates facing each other can abut against the two sides of the half-box component respectively. When the four clamping blocks are above the first conveyor, the two first clamping plates are above the lifting plate.

[0023] In this invention, in the initial state, the height of the lifting plate is flush with the conveyor belts of the first and second conveyors. The first movable frame is suspended above the discharge end of the first conveyor. When the part to be folded moves to the discharge end of the first conveyor, the four clamping blocks move simultaneously toward the center of the first movable frame. The clamping slots of the four clamping blocks simultaneously abut against the upper half of the four corners of the inner box of the part to be folded, thereby firmly clamping the part to be folded without contacting the glued packaging paper. While the four clamping blocks are clamping the part to be folded, the two first clamping plates above the lifting plate move toward each other. If there is a glued half-box-shaped part on the lifting plate at this time, the two first clamping plates can clamp the lifting plate. The half-box-shaped component on the plate is then moved horizontally towards the second conveyor by the first moving frame, which drives four clamping blocks to clamp the component to be folded and move it towards the lifting plate. At the same time, it drives two first clamping plates to clamp the half-box-shaped component and move it towards the second conveyor. When the component to be folded moves to the lifting plate, the half-box-shaped component moves to the conveyor belt of the second conveyor. At this time, the clamping blocks and first clamping plates reset and release the component to be folded and the half-box-shaped component respectively, completing the placement of the component to be folded and the half-box-shaped component. Then, the first moving frame drives the clamping blocks and first clamping plates to reset. By repeating the above process, the component to be folded can be transferred and placed on the lifting plate at the same time as the glued half-box-shaped component is transferred and placed on the second conveyor. By transferring the component to be folded and the half-box-shaped component at the same time, the production efficiency is improved.

[0024] 8) An automated production system for packaging boxes according to 1), wherein: The fixed structure includes a seventh bracket set below the discharge end of the second conveyor. The seventh bracket is equipped with a liftable placement plate and four side pressure plates that can move toward or away from the center of the placement plate. The placement plate and the four side pressure plates can simultaneously abut against the bottom and four outer side walls of the semi-box-shaped part. A discharge channel is fixedly connected to the seventh bracket. The discharge channel is located on the side of the placement plate away from the second conveyor. The discharge channel extends downward at an inlet at the upper end and an outlet at the lower end. An eighth support is mounted above the seventh support. The eighth support is equipped with a liftable third pressure plate that can simultaneously abut against the inner bottom surface and four inner side walls of the half-box part. The eighth support is also equipped with a shaping gripping unit, which is used to transfer the half-box part to the placement plate and to transfer the shaped half-box part to the discharge channel.

[0025] In this invention, when the half-box part moves to the discharge end of the second conveyor along the conveyor belt, the second conveyor stops running, the shaping and gripping unit grabs the half-box part and moves it to the placement plate, then the placement plate drives the half-box part to descend, and the four side pressure plates move toward the center of the placement plate until the placement plate and the four side pressure plates simultaneously abut against the bottom and four outer side walls of the half-box part, and the second conveyor resumes running until the next half-box part moves to its discharge end, at which point the second conveyor stops running again; The third pressure plate then moves downwards to abut against the inner wall of the half-box component. At this point, all parts of the half-box component are simultaneously clamped by the placement plate, side pressure plate, and third pressure plate. The placement plate, side pressure plate, and third pressure plate apply pressure to the half-box component, strengthening the adhesion between the packaging paper and the inner box, thus shaping the half-box component. Afterwards, the placement plate, side pressure plate, and third pressure plate are all reset. While the shaping and gripping unit moves the shaped half-box component from the placement plate to the discharge channel for discharge, it also moves the next half-box component to the placement plate. By repeating the above process, the half-box components can be shaped continuously, saving manpower and improving production efficiency.

[0026] 9) An automated production system for packaging boxes according to 8), wherein: The height of the second conveyor belt is flush with the height of the discharge channel inlet. The shaping gripping unit includes a second movable frame that can reciprocate along the arrangement direction of the second conveyor, the placement plate and the discharge channel inlet. The second movable frame is provided with two second clamping plates that can move towards or away from each other. The side of the two second clamping plates facing each other can abut against the two sides of the half-box part respectively. A push rod is fixedly connected to the side of the second movable frame facing the discharge channel. A push block is fixedly connected to the other end of the push rod. The push block can abut against the side of the half-box part on the placement plate facing the second conveyor.

[0027] In this invention, in the initial state, the height of the placement plate is flush with the height of the second conveyor belt and the discharge channel inlet. The second movable frame is suspended above the discharge end of the second conveyor. When a half-box-shaped component moves to the discharge end of the second conveyor, the two second clamping plates move towards each other until the half-box-shaped component is clamped between them. Then, the second movable frame moves horizontally towards the discharge channel inlet, causing the two second clamping plates to move the half-box-shaped component towards the placement plate, and simultaneously causing the push rod and push block to move towards the discharge channel inlet. If at this time there are any... Once the half-box part has been shaped, the pusher block can move it towards the discharge channel inlet. When the half-box part held by the second clamping plate moves to the placement plate, the shaped half-box part is pushed into the discharge channel by the pusher block. At this time, the second clamping plate resets and releases the half-box part to complete the placement. Subsequently, the second moving frame drives the second clamping plate, push rod and pusher block to reset. By repeating the above process, the shaped half-box part can be pushed into the discharge channel for discharge while the half-box part is being transferred and placed on the placement plate, thereby improving production efficiency.

[0032] In the gluing section of this embodiment, the coating structure is a glue machine 25 for applying glue to the upper surface of the packaging paper 24. Specifically, in the prior art, the glue machine 25 is a special equipment for gluing paper in the printing and packaging industry. It is used to apply glue to the surface of materials such as paper, cardboard, and wood veneer. Its working principle is to uniformly apply glue to the surface of the paper while conveying the paper to its discharge end by a glue roller.

A second cylinder 15 is fixedly connected to the top of the support 14 by bolts and nuts. The output end of the second cylinder 15 passes downward through the support 14 and is fixedly connected to a connecting... Block 16, the second cylinder 15 is used to drive the connecting block 16 to rise and fall. The connecting block 16 is equipped with a first gripper 17 on the side facing the feeding table 10. Thus, the first cylinder 13 drives the support 14 to drive the second cylinder 15, the connecting block 16 and the first gripper 17 to move horizontally back and forth between the worktable 9 and the feeding table 10. The second cylinder 15 drives the connecting block 16 to drive the first gripper 17 to rise and fall, so that the first gripper 17 can move horizontally back and forth and rise and fall between the worktable 9 and the feeding table 10. The first gripper 17 is a pneumatic suction cup for adsorbing and gripping the packaging paper 24. In the prior art, the pneumatic suction cup is an industrial device that uses compressed air as a power source and generates negative pressure through a vacuum generator to adsorb and transport objects. Its core principle is to use vacuum suction to tightly adsorb objects on the surface of the suction cup, and to realize the gripping, moving and releasing of objects through the control of the pneumatic system.

[0034] See Figure 4 and Figure 5 As shown, the second support 12 includes support plates disposed on both sides of the workbench 9. A rotating rod 23 is inserted between the two support plates and is rotatably connected to the support plates via bearings. A first motor 18 is installed on the side of one of the support plates away from the workbench 9 via bolts and nuts. The output end of the first motor 18 is fixedly connected to the end of the rotating rod 23. Two support blocks 19 are welded onto the rotating rod 23. A roller shaft 20 is inserted between the two support blocks 19 and is rotatably connected to the support blocks 19 via bearings. A second motor 21 is installed on the side of any support block 19 away from the other support block 19 via bolts and nuts. The output end of the second motor 21 is fixedly connected to the end of the roller shaft 20. A roller wheel 22 is keyed onto the roller shaft 20, and the side of the roller wheel 22 can abut against the top of the feed table 10.

[0035] In the gluing section of this embodiment, before production starts, the operator stacks multiple sheets of packaging paper 24 on the workbench 9 to form a stack. The first gripper 17 is suspended above the stack, and the roller 22 is suspended above the feeding table 10. After production starts, the first gripper 17 moves downward to grip a single sheet of packaging paper 24, then lifts it and moves it towards the feeding table 10, transferring the packaging paper 24 to the feeding table 10 so that the packaging paper 24 is located below the roller 22. After the packaging paper 24 is in place, the first motor 18 drives the rotating rod 23 to rotate, driving the two... The support block 19 swings downward synchronously, and the roller shaft 20, roller wheel 22 and second motor 21 swing downward synchronously with the support block 19 until the roller wheel 22 comes into contact with the packaging paper 24 on the feeding table 10. At this time, the first motor 18 stops running, the first gripper 17 releases the packaging paper 24 and moves back to its original position, the second motor 21 starts and drives the roller shaft 20 to rotate, which in turn drives the roller wheel 22 to rotate. The packaging paper 24 is fed into the glue machine 25 by the friction between the roller wheel 22 and the packaging paper 24, and the glue roller of the glue machine 25 applies glue to the upper surface of the packaging paper 24.

[0036] After the current packaging paper 24 is fed, the second motor 21 stops running, and the first motor 18 drives the rotating rod 23 to rotate and reset, driving the support block 19, roller shaft 20 and roller 22 to swing up and reset. This completes the feeding of a single sheet of packaging paper 24. Repeating the above process can continuously feed the packaging paper 24 to the glue machine 25. Then, the glue roller of the glue machine 25 applies glue to the upper surface of the packaging paper 24. At the same time, the glued packaging paper 24 is conveyed by the glue roller to the discharge end of the glue machine 25 and moves to the first conveyor 7 connected to the discharge end of the glue machine 25, so that the glued packaging paper 24 enters the box placement section.

[0037] In the box placement section of this embodiment, see Figure 6 As shown, the inner box placement structure includes an inner box conveyor 26 disposed on one side of the first conveyor 7. The inner box conveyor 26 is a belt conveyor with a conveyor belt, used to convey inner boxes 27 towards the first conveyor 7. A third support 28 is provided above the inner box conveyor 26. A second gripping member 30 is provided on the third support 28, which can move horizontally back and forth between the first conveyor 7 and the inner box conveyor 26 and can be raised and lowered. Specifically, a first linear motor 29 is fixedly connected to the third support 28 by bolts and nuts. A third cylinder is fixedly connected to the slide of machine 29 by bolts and nuts. The output end of the third cylinder is fixedly connected to a second gripper 30. The first linear motor 29 is used to drive the third cylinder and the second gripper 30 to move horizontally back and forth between the first conveyor 7 and the inner box conveyor 26. The third cylinder is used to drive the second gripper 30 to lift and lower, so that the second gripper 30 can move horizontally back and forth between the first conveyor 7 and the inner box conveyor 26 and can be lifted and lowered. The second gripper 30 is a pneumatic suction cup used to adsorb and grip the inner box 27.

[0038] The pressing structure includes a fourth support 31 mounted above the first conveyor 7. The fourth support 31 is equipped with a liftable first pressure plate 32. The first pressure plate 32 is used to press the inner box 27 and the packaging paper 24 together to form the folded part. Specifically, a fourth cylinder is fixedly connected to the fourth support 31 by bolts and nuts. The output end of the fourth cylinder is fixedly connected to the top of the first pressure plate 32 by bolts and nuts. The fourth cylinder is used to drive the first pressure plate 32 to rise and fall.

[0039] In the box-setting section of this embodiment, in the initial state, the second gripper 30 is suspended above the inner box conveyor 26, and the first pressure plate 32 is suspended above the first conveyor 7. The first conveyor 7 continuously conveys the packaging paper 24 that has been glued in the gluing section, so that the glued packaging paper 24 passes through the inner box conveyor 26 and the first pressure plate 32 in sequence. When the glued packaging paper 24 moves to the position corresponding to the inner box conveyor 26, the first conveyor 7 stops running, the second gripper 30 moves down to grip the inner box 27, then lifts it and moves it towards the first conveyor 7, and moves the inner box 27 to the bottom surface 1 of the packaging paper 24. Then it descends until the bottom of the inner box 27 is attached to the bottom surface 1 of the packaging paper 24, so that the bottom of the inner box 27 is initially bonded to the bottom surface 1 of the packaging paper 24. Then the second gripper 30 releases the inner box 27 and moves back to its original position, and the first conveyor 7 resumes operation.

[0040] When the packaging paper 24 with the inner box 27 attached moves along the conveyor belt of the first conveyor 7 to below the first pressure plate 32, the first conveyor 7 stops running again, and the first pressure plate 32 moves down to abut against the top of the inner box 27, applying pressure to the inner box 27 and the packaging paper 24, pressing the inner box 27 and the packaging paper 24 to strengthen the adhesion between them, thereby producing a foldable part composed of the inner box 27 and the packaging paper 24. Then the first pressure plate 32 is raised and reset, and the first conveyor 7 resumes operation. By repeating the above process, foldable parts can be produced continuously, and the foldable parts produced can be transported by the first conveyor 7 to the folding structure connected to the discharge end of the first conveyor 7, so that the foldable parts can enter the forming section.

[0041] In the folding structure of the forming section in this embodiment, see... Figure 7 , Figure 8 and Figure 9As shown, the folding structure includes a fifth support 33 located between the first conveyor 7 and the second conveyor 8. The fifth support 33 is provided with a long side folding unit 34, a support ear folding unit 35 and a short side folding unit 36 ​​from top to bottom. The fifth support 33 is also provided with a liftable lifting plate 37. The lifting plate 37 has a long rectangular structure that matches the size of the bottom surface 1 of the packaging paper 24. The longer side of the lifting plate 37 is called the long side, and the shorter side is called the short side. Specifically, a fifth cylinder 47 is fixedly connected to the fifth support 33 by bolts and nuts. The fifth cylinder 47 is located below the short side folding unit 36. The output end of the fifth cylinder 47 is fixedly connected to the bottom of the lifting plate 37. The fifth cylinder 47 is used to drive the lifting plate 37 to rise and fall. During the rising and falling process, the lifting plate 37 can pass through the long side folding unit 34, the support ear folding unit 35 and the short side folding unit 36 ​​in sequence.

[0042] A sixth support is mounted above the fifth support 33. The sixth support is equipped with a second pressure plate 45 that can be raised and lowered. Specifically, a sixth cylinder 46 is fixedly connected to the sixth support by bolts and nuts. The output end of the sixth cylinder 46 is fixedly connected to the top of the second pressure plate 45. The sixth cylinder 46 is used to drive the second pressure plate 45 to rise and fall. The second pressure plate 45 can simultaneously abut against the inner bottom surface 1 and the four inner side walls of the inner box 27. The sixth support is also equipped with a folding gripping unit 38. The folding gripping unit 38 is used to transfer the part to be folded to the lifting plate 37 and to transfer the half-box type part to the second conveyor 8.

[0043] See Figure 9 As shown, the long side folding unit 34 includes two long side folding members arranged facing each other on the fifth bracket 33. The two long side folding members are arranged along the width direction of the lifting plate 37. The long side folding members include a first fixing bar 39, a first push plate 40, and a first push plate 41 arranged sequentially from top to bottom on the fifth bracket 33. The first fixing bar 39, the first push plate 40, and the first push plate 41 can all reciprocate along the width direction of the lifting plate 37. Specifically, the fifth bracket 33 is fixedly connected by bolts and nuts to a first folding cylinder 42 for driving the first fixing bar 39 to reciprocate along the width direction of the lifting plate 37, and a first folding cylinder 42 for driving the first fixing bar 39 to reciprocate. A second folding cylinder 43, which reciprocates along the width direction of the lifting plate 37, and a third folding cylinder 44, which drives the first push plate 41 to reciprocate along the width direction of the lifting plate 37, are provided. The output ends of the first folding cylinder 42, the second folding cylinder 43, and the third folding cylinder 44 are fixedly connected to the first fixing strip 39, the first pusher 40, and the first push plate 41, respectively. The first fixing strip 39, the first pusher 40, and the first push plate 41 are attached to each other in sequence. The opposing sides of the two first fixing strips 39 are arc-shaped, and the opposing sides of the two first push plates 41 can respectively abut against the two long sides of the lifting plate 37.

[0044] The lug folding unit 35 includes two lug folding pieces arranged opposite each other on the fifth bracket 33. The two lug folding pieces are arranged along the width direction of the lifting plate 37. Each lug folding piece includes a moving rod 48 that can reciprocate along the width direction of the lifting plate 37. Specifically, a fourth folding cylinder 50 is fixedly connected to the fifth bracket 33 by bolts and nuts. The output end of the fourth folding cylinder 50 is fixedly connected to the moving rod 48. The fourth folding cylinder 50 is used to drive the moving rod 48 to reciprocate along the width direction of the lifting plate 37. Two folding blocks 49 are welded on the moving rod 48. The opposing sides of the two folding blocks 49 can respectively abut against the two short sides of the lifting plate 37.

[0045] The short side folding unit 36 ​​includes two short side folding members arranged opposite each other on the fifth bracket 33. The short side folding members are arranged along the length direction of the lifting plate 37. Each short side folding member includes a second fixing bar 51, a second push plate 52, and a second push plate 53 arranged sequentially from top to bottom on the fifth bracket 33. The second fixing bar 51, the second push plate 52, and the second push plate 53 can all reciprocate along the length direction of the lifting plate 37. Specifically, a fifth folding cylinder for driving the second fixing bar 51 to reciprocate along the width direction of the lifting plate 37 is fixedly connected to the fifth bracket 33 by bolts and nuts. The sixth folding cylinder drives the second push plate 52 to reciprocate along the width direction of the lifting plate 37, and the seventh folding cylinder drives the second push plate 53 to reciprocate along the width direction of the lifting plate 37. The output ends of the fifth folding cylinder, the sixth folding cylinder, and the seventh folding cylinder are fixedly connected to the second fixing bar 51, the second push plate 52, and the second push plate 53, respectively. The second fixing bar 51, the second push plate 52, and the second push plate 53 are in sequence attached to each other. The opposing sides of the two second fixing bars 51 are both arc-shaped, and the opposing sides of the two second push plates 53 can respectively abut against the two short sides of the lifting plate 37.

[0046] In the folding structure of the forming section of this embodiment, when the part to be folded moves to the discharge end of the first conveyor 7 along with the conveyor belt of the first conveyor 7, the first conveyor 7 stops running. The folding gripping unit 38 grips the part to be folded and transfers it to the lifting plate 37, aligning the bottom surface 1 of the packaging paper 24 in the part to be folded with the top of the lifting plate 37. The second pressure plate 45 descends and extends into the inner box 27 of the part to be folded, abutting against the inner wall of the inner box 27, clamping the part to be folded between the lifting plate 37 and the second pressure plate 45. Then the lifting plate 37 and the second pressure plate 45 descend, driving the part to be folded to move downwards, passing through the long side folding unit 34, the support ear folding unit 35 and the short side folding unit 36 ​​in sequence. At the same time, the first conveyor 7 resumes running until the next part to be folded moves to its discharge end, at which point the first conveyor 7 stops running again.

[0047] During the downward movement of the part to be folded, the specific operation modes of the lifting plate 37, the second pressure plate 45, the long side folding unit 34, the support lug folding unit 35, and the short side folding unit 36 ​​are as follows: (1) Before the folded part descends to the long side folding unit 34, the two first fixing bars 39 in the long side folding unit 34 move towards each other along the width direction of the lifting plate 37 until the distance between the two first fixing bars 39 is just enough for the lifting plate 37 to pass through.

[0048] Since the size of the lifting plate 37 matches the bottom surface 1 of the packaging paper 24, and the bottom surface 1 of the packaging paper 24 in the folded part is aligned with the top of the lifting plate 37, the short side 4 and long side 2 of the packaging paper 24 in the folded part both extend out of the lifting plate 37. Since the distance between the two first fixing strips 39 is just enough for the lifting plate 37 to pass through, as the folded part continues to descend and pass through the first fixing strips 39, the long side 2 of the packaging paper 24 in the folded part is blocked by the arc surface of the first fixing strips 39 and folds upward toward the outer wall of the long side plate of the inner box 27 in the folded part.

[0049] When the item to be folded descends to the top of its inner box 27 and is level with the top of the first push plate 41, the lifting plate 37 and the second pressure plate 45 stop moving, the first fixing strip 39 moves back to its original position, and the two first push plates 41 move towards each other until they abut against the long side of the lifting plate 37, pressing the long side 2 of the packaging paper 24 against the outer wall of the long side plate of the inner box 27 to make them stick together.

[0050] Then the second pressure plate 45 moves upward to detach from the part to be folded, and the two first push plates 40 move towards each other along the width direction of the lifting plate 37. Since the top of the inner box 27 is flush with the top of the first push plate 41 at this time, the long bending surface 3 of the packaging paper 24 extends upward from the first push plate 41 after the long side 2 is folded upward. Since the top of the first push plate 40 is in contact with the top of the first push plate 41, the first push plate 40 can push the long bending surface 3 to fold towards the middle of the inner box 27, so that the long bending surface 3 is perpendicular to the long side plate of the inner box 27.

[0051] Then the first push plate 40 resets, and the second pressure plate 45 moves downward to push the long bending surface 3 downward until the second pressure plate 45 is completely against the inner wall of the inner box 27. At this time, the long side 2 of the packaging paper 24, the long side plate of the inner box 27, and the long bending surface 3 of the packaging paper 24 are held between the second pressure plate 45 and the first push plate 41. The second pressure plate 45 and the first push plate 41 jointly apply pressure to the three, completing the adhesion between the long side 2 of the packaging paper 24 and the outer wall of the long side plate of the inner box 27, and the adhesion between the long bending surface 3 of the packaging paper 24 and the inner side wall of the long side plate of the inner box 27. Then the first push plate 41 resets, and the second pressure plate 45 and the lifting plate 37 together drive the part to be folded to continue to descend.

[0052] (2) After the long side 2 of the packaging paper 24 is folded upward and glued to the outer wall of the long side plate of the inner box 27, the ears 6 on both sides of the long side 2 are folded upward to be perpendicular to the short side plate of the inner box 27 and extend out of the lifting plate 37. When the piece to be folded descends to the ear folding unit 35, the lifting plate 37 and the second pressure plate 45 stop moving. The two moving rods 48 move towards each other along the length of the lifting plate 37, driving the folding block 49 to push the ears 6 of the packaging paper 24 to fold to the outer wall of the short side plate of the inner box 27, and finally glue the ears 6 to the outer wall of the short side plate of the inner box 27. Then the folding block 49 is reset, and the second pressure plate 45 and the lifting plate 37 together drive the piece to be folded to continue to descend.

[0053] (3) Referring to the operation mode of the lifting plate 37, the second pressure plate 45 and the long side folding unit 34 in (2), the operation mode of the second fixing strip 51, the second push piece 52 and the second push plate 53 in the short side folding unit 36 ​​correspond one-to-one with the operation mode of the first fixing strip 39, the first push piece 40 and the first push plate 41 in the long side folding unit 34. Finally, the short side 4 of the packaging paper 24 is bonded to the outer wall of the short side plate of the inner box 27, and the short bending surface 5 of the packaging paper 24 is bonded to the inner wall of the short side plate of the inner box 27 to obtain the bonded half box part.

[0054] Subsequently, the lifting plate 37 and the second pressure plate 45 rise and reset. While the folding gripping unit 38 transfers the folded half-box part from the lifting plate 37 to the second conveyor 8, it also transfers the next part to be folded to the lifting plate 37. By repeating the above process, half-box parts can be continuously produced. The half-box parts are then transported to the shaping structure by the second conveyor 8.

[0055] To achieve the function of the folding gripping unit 38 in the above process, see [link / reference]. Figure 8 and Figure 10As shown, the height of the conveyor belt of the first conveyor 7 is flush with the height of the conveyor belt of the second conveyor 8. The folding gripping unit 38 includes a first movable frame 54 that can reciprocate along the arrangement direction of the first conveyor 7, the lifting plate 37, and the second conveyor 8. Specifically, a second linear motor 55 is fixedly connected to the sixth bracket by bolts and nuts. The slide of the second linear motor 55 is fixedly connected to the first movable frame 54. The second linear motor 55 is used to drive the first movable frame 54 to reciprocate along the arrangement direction of the first conveyor 7, the lifting plate 37, and the second conveyor 8. The bottom of the first movable frame 54 is provided with four clamping blocks 56. The clamping blocks 56 can move toward or away from the center of the first movable frame 54. Specifically, the bottom of the first movable frame 54 is fixedly connected to four first clamping cylinders 58 by bolts and nuts. The output ends of the four first clamping cylinders 58 are respectively fixedly connected to the four clamping blocks 56. 58 is used to drive the clamping block 56 to move toward or away from the center of the first moving frame 54; the clamping block 56 has a clamping groove 57 on its side, and the four clamping grooves 57 can simultaneously abut against the upper half of the four corners of the inner box 27. The first moving frame 54 is provided with two first clamping plates 59 that can move toward or away from each other on the side facing the second conveyor 8. Specifically, two extension blocks 60 are welded to the side of the first moving frame 54 facing the second conveyor 8. The two extension blocks 60 are respectively fixedly connected to the second clamping cylinders 61 by bolts and nuts. The output ends of the two second clamping cylinders 61 are respectively fixedly connected to the two first clamping plates 59. The two second clamping cylinders 61 are used to drive the two first clamping plates 59 to move toward or away from each other; the side of the two first clamping plates 59 facing each other can abut against the two sides of the half box part. When the four clamping blocks 56 are above the first conveyor 7, the two first clamping plates 59 are above the lifting plate 37.

[0056] The folding gripping unit 38 operates as follows: In the initial state, the height of the lifting plate 37 is flush with the conveyor belts of the first conveyor 7 and the second conveyor 8. The first moving frame 54 is suspended above the discharge end of the first conveyor 7. When the part to be folded moves to the discharge end of the first conveyor 7, the four clamping blocks 56 move simultaneously toward the center of the first moving frame 54. The clamping slots 57 of the four clamping blocks 56 simultaneously abut against the upper half of the four corners of the inner box 27 in the part to be folded, thereby firmly clamping the part to be folded without contacting the glued packaging paper 24. While the four clamping blocks 56 are clamping the part to be folded, the two first clamping plates 59 located above the lifting plate 37 move toward each other. If there are glued half-box parts on the lifting plate 37 at this time, the two first clamping plates 59... The first moving frame 54 then moves horizontally toward the second conveyor 8, which in turn moves the four clamping blocks 56 to clamp the part to be folded toward the lifting plate 37. At the same time, it moves the two first clamping plates 59 to clamp the half-box part toward the second conveyor 8. When the part to be folded moves to the lifting plate 37, the half-box part moves to the conveyor belt of the second conveyor 8. At this time, the clamping blocks 56 and the first clamping plates 59 reset and release the part to be folded and the half-box part respectively, completing the placement of the part to be folded and the half-box part. Then, the first moving frame 54 moves the clamping blocks 56 and the first clamping plates 59 to reset. By repeating the above process, the half-box part that has been glued can be transferred to the second conveyor 8 at the same time as the part to be folded is transferred to the lifting plate 37. By transferring the part to be folded and the half-box part at the same time, the production efficiency is improved.

[0057] In the shaping structure of the molding section in this embodiment, see... Figure 11 , Figure 12 and Figure 13 As shown, the shaping structure includes a seventh bracket 62 located below the discharge end of the second conveyor 8. The seventh bracket 62 has a liftable placement plate 63. Specifically, a first shaping cylinder is fixedly connected to the seventh bracket 62 by bolts and nuts. The output end of a second shaping cylinder 66 is fixedly connected to the bottom of the placement plate 63. The first shaping cylinder is used to drive the placement plate 63 to rise and fall. The seventh bracket 62 also has four side pressure plates 65 that can move towards or away from the center of the placement plate 63. Specifically, four side pressure plates 65 are fixedly connected to the seventh bracket 62 by bolts and nuts. The output ends of the four second shaping cylinders 66 are fixedly connected to the four side pressure plates 65 respectively. The second shaping cylinders 66 are used to drive the side pressure plates 65 to move toward or away from the center of the placement plate 63. The placement plate 63 and the four side pressure plates 65 can simultaneously abut against the bottom and four outer side walls of the semi-box part. The seventh bracket 62 is welded with a discharge channel 67. The discharge channel 67 is located on the side of the placement plate 63 away from the second conveyor 8. The discharge channel 67 extends downward at an inlet at the upper end and an outlet at the lower end.

[0058] An eighth support is mounted above the seventh support 62. The eighth support has a liftable third pressure plate 68. Specifically, a third shaping cylinder 69 is fixedly connected to the eighth support by bolts and nuts. The output end of the third shaping cylinder 69 is fixedly connected to the top of the third pressure plate 68. The third shaping cylinder 69 is used to drive the third pressure plate 68 to rise and fall. The third pressure plate 68 can simultaneously abut against the inner bottom surface 1 and the four inner side walls of the half-box part. The eighth support is also equipped with a shaping gripping unit 64. The shaping gripping unit 64 is used to transfer the half-box part to the placement plate 63 and to transfer the shaped half-box part to the discharge channel 67.

[0059] In the shaping structure of the forming section of Embodiment 1, when the half-box part moves to the discharge end of the second conveyor 8 along with the conveyor belt of the second conveyor 8, the second conveyor 8 stops running. The shaping gripping unit 64 grips the half-box part and moves it to the placement plate 63. Then, the placement plate 63 drives the half-box part to descend, and the four side pressure plates 65 move toward the center of the placement plate 63 until the placement plate 63 and the four side pressure plates 65 simultaneously abut against the bottom and four outer side walls of the half-box part. At the same time, the second conveyor 8 resumes running until the next half-box part moves to its discharge end, at which point the second conveyor 8 stops running again.

[0060] Subsequently, the third pressure plate 68 moves downwards to abut against the inner wall of the half-box component. At this time, all parts of the half-box component are simultaneously clamped by the placement plate 63, the side pressure plate 65, and the third pressure plate 68. The placement plate 63, the side pressure plate 65, and the third pressure plate 68 apply pressure to the half-box component, strengthening the adhesion between the packaging paper 24 and the inner box 27 in the half-box component, thus shaping the half-box component. Then, the placement plate 63, the side pressure plate 65, and the third pressure plate 68 are all reset. While the shaping and gripping unit 64 transfers the shaped half-box component from the placement plate 63 to the discharge channel 67 for discharge, it also transfers the next half-box component to the placement plate 63. By repeating the above process, the half-box components can be shaped continuously.

[0061] To achieve the function of the shaping and grasping unit 64 in the above process, see [link to relevant documentation]. Figure 12 and Figure 13As shown, the height of the conveyor belt of the second conveyor 8 is flush with the height of the inlet of the discharge channel 67. The shaping and gripping unit 64 includes a second movable frame 70 that can reciprocate along the arrangement direction of the second conveyor 8, the placement plate 63, and the inlet of the discharge channel 67. Specifically, a third linear motor is fixedly connected to the eighth bracket by bolts and nuts. The slide of the third linear motor is fixedly connected to the second movable frame 70. The third linear motor is used to drive the second movable frame 70 to reciprocate along the arrangement direction of the second conveyor 8, the placement plate 63, and the inlet of the discharge channel 67. The second movable frame 70 is provided with two movable parts that can move towards or away from each other. The two moving second clamping plates 71 can abut against the two sides of the half-box-shaped part respectively. Specifically, two clamping plate cylinders 72 are fixedly connected to the second moving frame 70 by bolts and nuts. The output ends of the two clamping plate cylinders 72 are fixedly connected to the two second clamping plates 71 respectively. The two clamping plate cylinders 72 are used to drive the two second clamping plates 71 to move towards or away from each other. A push rod 73 is welded to the side of the second moving frame 70 facing the discharge channel 67. A push block 74 is welded to the other end of the push rod 73. The push block 74 can abut against the side of the half-box-shaped part on the placement plate 63 facing the second conveyor 8.

[0062] The operation mode of the shaping and gripping unit 64 is as follows: In the initial state, the height of the placement plate 63 is flush with the height of the conveyor belt of the second conveyor 8 and the inlet of the discharge channel 67. The second moving frame 70 is suspended above the discharge end of the second conveyor 8. When a half-box-shaped part moves to the discharge end of the second conveyor 8, the two second clamping plates 71 move towards each other until the half-box-shaped part is clamped between them. Then, the second moving frame 70 moves horizontally towards the inlet of the discharge channel 67, driving the two second clamping plates 71 to move the half-box-shaped part clamped in the placement plate 63, and at the same time driving the push rod 73 and the push block 74 to move towards the inlet of the discharge channel 67. If the placement plate 63 is placed at this time, the two second clamping plates 71 move towards the placement plate 63, and at the same time drive the push rod 73 and the push block 74 to move towards the inlet of the discharge channel 67. If there is a shaped half-box on plate 63, push block 74 can push the shaped half-box to move towards the inlet of discharge channel 67. When the half-box held by the second clamping plate 71 moves to the placement plate 63, the shaped half-box is pushed into the discharge channel 67 by the push plate. At this time, the second clamping plate 71 resets and releases the half-box to complete the placement. Then the second moving frame 70 drives the second clamping plate 71, push rod 73 and push block 74 to reset. By repeating the above process, the shaped half-box can be pushed into the discharge channel 67 for discharge while the half-box is being transferred and placed on the placement plate 63, thereby improving production efficiency.

[0063] In summary, in this embodiment, the gluing section first applies glue to the upper surface of the packaging paper 24, and then the glued packaging paper 24 is sent to the box placement section, where the inner box 27 is placed on the upper surface of the packaging paper 24, so that the bottom of the inner box 27 is bonded to the bottom surface 1 of the packaging paper 24 to form a folding part. The folding part is then sent to the forming section, where the folding structure bonds the various parts of the packaging paper 24 to the corresponding positions of the inner box 27 to form a half-box part. The shaping structure in the forming section then presses and shapes the half-box part to improve the bonding strength between the packaging paper 24 and the inner box 27. Finally, the shaped half-box part is discharged, thereby realizing the automated mass production of half-box parts, saving manpower and improving production efficiency.

[0064] Example 2 differs from Example 1 in that it includes two production lines, each including a gluing section, a box-setting section, and a molding section. The two production lines can simultaneously produce half-box parts 80 and also include a belt conveyor 75. The outlets 67 of the molding sections of the two production lines are all facing the conveyor belt of the conveyor and are arranged sequentially along the conveying direction.

[0065] See Figure 14 As shown, in this embodiment, along the conveying direction of the discharge conveyor 75, the outlets of the two discharge channels 67 are defined as the first outlet 76 and the second outlet 77, respectively. The top surface of the conveyor belt of the discharge conveyor 75 is divided in half along its conveying direction into the first conveying area 78 and the second conveying area 79. The first outlet 76 and the second outlet 77 are both located above the discharge conveyor 75 and both face the first conveying area 78.

[0066] A V-shaped guide rod 81 is provided between the first outlet 76 and the second outlet 77. The two ends of the guide rod 81 are fixedly connected to the side of the discharge conveyor 75 away from the discharge channel 67 by bolts and nuts. The maximum distance between the guide rod 81 and the side of the discharge conveyor 75 away from the discharge channel 67 is equal to the width of the first conveying area 78. The guide rod 81 can guide the semi-box-shaped parts 80 that fall into the first conveying area 78 from the first outlet 76 to the second conveying area 79. The workpieces output from the second outlet 77 are conveyed along the first conveying area 78. In this way, while expanding the production capacity through dual production lines, the risk of semi-box-shaped parts 80 output from the two discharge channels 67 accumulating and getting stuck in the same area is reduced.
