Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to a glass packaging production line. Background Technology

[0002] Glass requires protection before transportation, such as being packed in cardboard boxes for external protection. For larger and heavier pieces of glass, one box can be used to package each piece of glass to further enhance protection. Current cardboard box packaging for glass involves multiple workstations, all of which require manual intervention, such as box support, glass packing, and box sealing. Manual packaging cannot guarantee consistent packaging quality for each box. Therefore, there is an urgent need to develop a dedicated production line for individually packaging each piece of glass in cardboard boxes to ensure uniform packaging quality and reduce labor costs. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a glass packaging production line that aims to ensure the uniformity of quality of each piece of glass packaging.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A glass packaging production line includes, sequentially arranged from upstream to downstream, a bottom paperboard feeding device, a bottom paperboard folding and forming device, a glass feeding device, a face paperboard short-side folding and bonding device, and a face paperboard long-side folding and bonding device. The bottom paperboard feeding device feeds bottom paperboards one by one into the bottom paperboard folding and forming device. The bottom paperboard folding and forming device folds the pre-reserved fold lines on the two long sides and two short sides of the bottom paperboard upwards and uses glue to bond the long and short sides of the bottom paperboard, thus forming a bottom paperboard with a structure for accommodating glass. The cavity; the glass feeding device is used to place the glass into the cavity; the short-side folding and bonding device for the face paper is used to cover the face paper onto the upper surface of the formed bottom paper, and to fold down the fold lines reserved on the two short sides of the face paper to form short-side folded edges, and to bond the short-side folded edges to the short sides of the bottom paper with glue; the long-side folding and bonding device for the face paper is used to fold down the fold lines reserved on the two long sides of the face paper to form long-side folded edges, and to bond the long-side folded edges to the long sides of the bottom paper with glue.

[0006] Beneficial effects:

[0007] This invention provides a glass packaging production line that integrates the processes of bottom paperboard feeding, bottom paperboard folding and forming, glass feeding, and face paperboard short-side folding and bonding by setting up a bottom paperboard feeding device, a bottom paperboard forming device, glass placement in the cavity of the bottom paperboard, face paperboard feeding, and face paperboard bonding to the bottom paperboard, thereby achieving continuous production and reducing the problem of inconsistent batch quality of glass packaging caused by human intervention.

[0025] This invention provides a glass packaging production line. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

[0026] Please see Figure 1 This invention provides a glass packaging production line, comprising, sequentially arranged from upstream to downstream, a bottom paperboard feeding device A, a bottom paperboard folding and forming device B, a glass feeding device C, a face paperboard short side folding and bonding device D, and a face paperboard long side folding and bonding device E; the bottom paperboard feeding device A is used to feed bottom paperboards 10 one by one into the bottom paperboard folding and forming device B; the bottom paperboard folding and forming device B is used to fold the pre-reserved folding lines on the two long sides and two short sides of the bottom paperboard 10 upwards, and use glue to bond the long sides and short sides of the bottom paperboard, so that the bottom paperboard 10 forms a structure for accommodating... The cavity of glass 20; the glass feeding device C is used to place glass 20 into the cavity; the short side folding and bonding device D of the face paperboard is used to cover the face paperboard 30 onto the upper surface of the formed bottom paperboard 10, and to fold down the fold lines reserved on the two short sides of the face paperboard 30 to form short side folded edges, and to bond the short side folded edges to the short sides of the bottom paperboard with glue; the long side folding and bonding device E of the face paperboard is used to fold down the fold lines reserved on the two long sides of the face paperboard 30 to form long side folded edges, and to bond the long side folded edges to the long sides of the bottom paperboard with glue.

[0027] In actual use, multiple bottom paperboards 10 are stacked at the bottom paperboard feeding station. The bottom paperboard feeding equipment A transports the bottom paperboards 10 to be bonded and formed one by one to the bottom paperboard folding and forming station. Since folding marks are pre-reserved on both the long and short sides of the bottom paperboard 10, at the bottom paperboard folding and forming station, the two long and two short sides on both sides can be folded upwards while the long and short sides at the four corners are bonded with glue. Then, it continues to be transported to the glass feeding station. Glass 20 is placed one by one into the cavity of the formed bottom paperboard. The bottom paperboard 10, with its open top, continues to be transported downstream until it reaches the face paperboard short side folding and bonding station. The face paperboard... The short-side folding and bonding equipment D conveys the face paperboard 30 one by one to the top of the open bottom paperboard 10, and covers the bottom paperboard 10 with the face paperboard 30. Then, the two short sides of the face paperboard 30 with the pre-made folding creases are folded down. The glue on the short side wall of the bottom paperboard 10 is used to glue the short sides of the face paperboard 30 and the bottom paperboard 10 together. Next, the carton is conveyed to the long-side folding and bonding station of the face paperboard. The long-side folding and bonding equipment E of the face paperboard 30 folds down on both sides. The glue on the long side wall of the bottom paperboard 10 is used to glue the long sides of the face paperboard 30 and the bottom paperboard 10 together. This allows the glass 20 to be loaded into the carton.

[0028] The aforementioned production line integrates the processes of feeding the bottom paperboard 10, forming the bottom paperboard 10, placing the glass 20 into the cavity of the bottom paperboard 10, feeding the top paperboard 30, and bonding the top paperboard 30 to the bottom paperboard 10 by using the bottom paperboard feeding equipment A, the bottom paperboard 10 folding and forming equipment B, the glass 20, the top paperboard 30, and the top paperboard 30 to the bottom paperboard 10. This achieves continuous production and can reduce the problem of inconsistent quality of glass 20 packaging batches caused by human intervention.

[0029] Please see Figure 2 In some embodiments, the bottom paperboard feeding device A includes a first frame A1, a feeding conveying mechanism A2 disposed on the first frame A1, a suction mechanism A3 connected to the feeding conveying mechanism A2, a feeding lifting mechanism A4 disposed on the first frame A1, and a feeding lifting platform A5 connected to the feeding lifting mechanism A4; the feeding lifting platform A5 is located below the suction mechanism A3, and the feeding lifting platform A5 is used to stack bottom paperboards; the feeding lifting mechanism A4 is used to drive the feeding lifting platform A5 to move up and down; the suction mechanism A3 is used to pick up the bottom paperboards on the feeding lifting platform A5 one by one, and the feeding conveying mechanism A2 is used to drive the suction mechanism A3 to reciprocate in the upstream and downstream directions.

[0030] Preparation: The operator can manually stack multiple bottom cardboard sheets on the loading lifting platform A5. To facilitate loading, the loading lifting platform A5 is initially located at the bottom of the first frame A1. Subsequently, the loading lifting mechanism A4 operates, raising the loading lifting platform A5 and the bottom cardboard sheets on it to a set height before stopping. Next, the loading conveying mechanism A2 drives the suction mechanism A3 located above the bottom cardboard sheets to absorb the topmost stacked bottom cardboard sheets, and moves the suction mechanism A3 and the bottom cardboard sheets along the X-axis (i.e., downstream direction) to provide bottom cardboard sheets for the next bottom cardboard sheet folding and forming process.

[0031] In some embodiments, the feeding and conveying mechanism A2 includes an X-axis helical rack A21 extending along the X-axis direction and disposed on the first frame A1, a conveying gear A22 meshing with the X-axis helical rack A21, a conveying motor A23 fixedly connected to the center of the conveying gear A22, and a conveying frame fixedly connected to the conveying motor A23; a transverse beam A25 extending along the X-axis direction is disposed on the conveying frame, and the suction mechanism A3 is fixedly connected to the transverse beam A25. Specifically, when the conveying motor A23 rotates, it drives the conveying gear A22 to rotate synchronously, thereby enabling the conveying frame connected to the conveying motor A23 to move synchronously along the X-axis direction. Since the conveying frame is fixedly connected to the transverse beam A25, and the suction mechanism A3 is disposed on the transverse beam A25, the suction mechanism A3 and the bottom cardboard on the suction mechanism A3 can be synchronously driven to move along the X-axis direction; after the bottom cardboard is fed, the entire feeding and conveying mechanism A2 is reset by the reverse rotation of the conveying motor A23.

[0032] In some embodiments, the conveyor frame includes an upper frame A241, a lower frame A242, and a middle partition A243. The upper frame A241 and the lower frame A242 are arranged vertically, and the middle partition A243 is located between the upper frame A241 and the lower frame A242. A feeding guide rod A244 is provided between the upper frame A241 and the lower frame A242, and the two ends of the feeding guide rod A244 are respectively connected to the conveyor belt. The upper frame A241 and the lower frame A242 are fixedly connected; a feeding guide cylinder A245 is also sleeved in the feeding guide rod A244, and the feeding guide cylinder A245 is fixedly connected to the middle partition plate A243; a feeding conveying cylinder A26 with its output end facing downward is also provided on the upper frame A241, and the output end of the feeding conveying cylinder A26 is fixedly connected to the middle partition plate A243; the transverse beam A25 is provided on the middle partition plate A243. Specifically, when the feeding lifting platform A5 rises to the set position, it stops operating. That is to say, the bottom cardboard will stop rising after it rises to the set position. The output end of the feeding conveying cylinder A26 extends downward, driving the middle partition A243 to move down synchronously under the guidance of the feeding guide rod A244. This causes the transverse beam A25 and the suction mechanism A3, which are fixed to the middle partition A243, to move down synchronously, so that the suction mechanism A3 can fully contact the upper surface of the bottom cardboard and ensure the adsorption of the bottom cardboard.

[0033] In some embodiments, two transverse beams A25 are configured, symmetrically arranged along the X-axis, and each transverse beam A25 is equipped with a suction mechanism A3. Multiple suction mechanisms A3 are arranged along the X-axis on each transverse beam A25, and each suction mechanism A3 is a vacuum suction cup. In this embodiment, the base cardboard is rectangular, with the long side extending along the X-axis and the short side extending along the Y-axis. The two transverse beams A25 are located above the base cardboard, and the multiple vacuum suction cups on the two transverse beams A25 are used to suction the base cardboard to ensure effective suction. Specifically, the transverse beams A25 can move along the Y-axis, thereby adjusting the position of the suction mechanism A3 relative to the base cardboard, meaning the suction mechanism A3 can feed base cardboard with different short side lengths.

[0034] In some embodiments, the first frame A1 is further provided with two X-axis feeding guide rails A11 extending along the X-axis direction. The two X-axis feeding guide rails A11 are symmetrically arranged along the X-axis direction, and X-axis feeding sliders A12 are slidably arranged on each of the two X-axis feeding guide rails A11. The inner sidewalls of the X-axis feeding sliders A12 located on both sides are fixedly connected to the corresponding outer sidewalls of the upper frame A241. By utilizing the cooperation of the X-axis feeding guide rails A11 and the X-axis feeding sliders A12, the conveyor frame can move smoothly back and forth along the X-axis direction of the first frame A1, while avoiding vibration of the bottom paperboard on the suction mechanism A3.

[0035] In some embodiments, the loading lifting mechanism A4 includes a loading lifting motor A41, a loading connecting rod A42 connected to the output end of the loading lifting motor A41, and two loading screw lifters A43 that are transmittedly connected to both ends of the loading connecting rod A42. The two loading screw lifters A43 extend along the Y-axis and are respectively fixed to the corresponding outer side wall of the loading lifting platform A5. The loading lifting motor A41 drives the two loading screw lifters A43 on both sides to operate synchronously, thus ensuring the smooth rising or falling of the loading lifting platform A5. Specifically, the loading screw lifter A43 is existing technology, mainly comprising a lifting body, a screw, and a screw nut. The lifting body contains a meshing worm gear and a worm, and the screw nut is threadedly connected to the screw. When the loading lifting motor A41 operates, it drives the screw nuts on both sides to move synchronously up or down on the screw, thereby raising or lowering the entire loading lifting platform A5.

[0036] In some embodiments, the first frame A1 is further provided with a Z-axis loading guide rail A13 extending along the Z-axis direction. The Z-axis loading guide rail A13 is located on the side of the loading screw lift A43. A Z-axis loading slider A14 is slidably mounted on the Z-axis loading guide rail A13, and the inner sidewall of the Z-axis loading slider A14 is fixedly connected to the corresponding outer sidewall of the loading lifting platform A5. Similarly, the cooperation of the Z-axis loading guide rail A13 and the Z-axis loading slider A14 can improve the stability of the loading lifting platform A5 when it rises or falls.

[0037] In some embodiments, the first frame A1 is further equipped with a bottom cardboard positioning sensor A15. The bottom cardboard positioning sensor A15 is used to sense the position of the topmost bottom cardboard placed on the loading lifting platform A5, and the bottom cardboard positioning sensor A15 is electrically connected to the loading lifting motor A41 through a control mechanism. Specifically, the loading lifting platform A5 and multiple stacked bottom cardboards rise synchronously. After the position of the topmost bottom cardboard is captured by the bottom cardboard positioning sensor A15, the control mechanism drives the loading lifting motor A41 to stop running. Subsequently, the output end of the loading conveying cylinder A26 extends downward to drive the suction mechanism A3 to move down and suck up the topmost bottom cardboard. Then, the output end of the loading conveying cylinder A26 retracts upward, driving the suction mechanism A3 and the bottom cardboard to rise, and under the action of the loading conveying mechanism A2, they move in the X-axis direction.

[0038] In some embodiments, the first frame A1 is further equipped with an upper limit sensor A18 and a lower limit sensor A19. The distance between the upper limit sensor A18 and the lower limit sensor A19 is the travel distance of the feeding lifting platform A5. The bottom cardboard positioning sensor A15 is located between the upper limit sensor A18 and the lower limit sensor A19. By using these two limit sensors, the travel distance of the feeding lifting platform A5 is limited, thereby ensuring the accuracy of the movement of the feeding lifting platform A5 and the bottom cardboard stacked on it in the Z-axis direction. Specifically, the positions of the upper limit sensor A18, the lower limit sensor A19, and the bottom cardboard positioning sensor A15 relative to the first frame A1 are all adjustable, making the operation of the bottom cardboard feeding device more precise. Furthermore, by adjusting the height of each sensor relative to the first frame A1, the bottom cardboard feeding device can feed bottom cardboard of different thicknesses.

[0039] Please see Figure 3 In some embodiments, the bottom cardboard folding and forming equipment B includes a second frame B1, a long-side flip plate B2 extending along the length of the second frame B1, a short-side flip plate B3 extending along the width of the second frame B1, a pressing mechanism B4 disposed on the second frame B1, an adsorption mechanism B5 connected to the pressing mechanism B4, and a folding mechanism B6 and a glue spraying mechanism B7 disposed at the four corners of the second frame B1; the long-side flip plate B2 is symmetrically arranged along the length of the second frame B1, and the long-side flip plate B2 is used to fold the two long sides of the bottom cardboard upwards; the short-side flip plate B3 extends along the width of the second frame B1... The components are symmetrically arranged in the direction of the angle, and the short side flip plate B3 is used to fold the two short sides of the bottom paperboard upwards; the height of the long side flip plate B2 is greater than the height of the short side flip plate B3; the adsorption mechanism B5 is used to adsorb the bottom paperboard to be folded, and the pressing mechanism B4 is used to drive the adsorption mechanism B5 down, so that the bottom paperboard adsorbed on the adsorption mechanism B5 contacts the long side flip plate B2 and the short side flip plate B3; the four glue spraying mechanisms B7 are all used to spray glue on the corners of the long side after folding upwards, and the four folding mechanisms B6 are all used to fold the corners of the long side after folding upwards again to form an adhesive edge parallel to the short side of the bottom paperboard.

[0040] After being fed, the bottom cardboard enters the folding and forming process. The upstream feeding conveyor A2 and suction mechanism A3 transport the bottom cardboard to below the adsorption mechanism B5. The pressing mechanism B4 drives the adsorption mechanism B5 downwards, bringing it into contact with the upper surface of the bottom cardboard and adsorbing it. Then, the upstream feeding conveyor A2 and suction mechanism A3 reset (i.e., move upstream). Subsequently, the pressing mechanism B4, adsorption mechanism B5, and the bottom cardboard continue to move downwards until the long side of the bottom cardboard contacts the long side flap B2. Under the action of the long side flap B2... The pre-creased long side is folded upwards. Then, the bottom cardboard continues to move downwards to the side of the glue spraying mechanism B7 and the folding mechanism B6. The glue spraying mechanism B7 and the folding mechanism B6 operate, spraying glue on the four corners of the long side and folding the long side again. After completing the above operations, the folding mechanism B6 resets. Subsequently, the pressing mechanism B4 continues to move downwards, using the short side flip plate B3 to fold the pre-creased short side upwards, so that the folded short side is bonded to the four corners of the long side sprayed with glue. To improve the bonding effect, the pressing mechanism B4 pauses at the positions of the long side flip plate B2 and the short side flip plate B3 before resetting upwards. Specifically, in this embodiment, the short side flip plate B3 is a profile.

[0041] In some embodiments, the pressing mechanism B4 includes a molding mounting base B41 disposed on the second frame B1, a pressing motor B42 disposed on the molding mounting base B41, a pressing gear B43 drivenly connected to the output end of the pressing motor B42, a pressing rack B44 meshing with the pressing gear B43, and a pressing bracket B45 fixedly connected to the pressing rack B44; the pressing rack B44 extends vertically, and the adsorption mechanism B5 is disposed on the pressing bracket B45. Specifically, the rotation of the pressing motor B42 drives the pressing gear B43 to rotate, and under the guidance of the pressing rack B44, the pressing rack B44 and the pressing bracket B45 rise or fall synchronously.

[0042] In some embodiments, the pressing bracket B45 is provided with a Z-axis forming guide rail B46 extending along the Z-axis direction, and the forming mounting base B41 is provided with a Z-axis forming slider that is slidably connected to the Z-axis forming guide rail B46; the second frame B1 is also provided with a guide forming cylinder B47, through which a guide forming rod B48 passes, and the lower end of the guide forming rod B48 is fixedly connected to the pressing bracket B45. Because the bottom paperboard of this embodiment has a large width, the pressing bracket B45 is relatively long, i.e., has a large volume. The cooperation of the Z-axis forming guide rail B46 and the Z-axis forming slider, and the guide forming cylinder B47 and the guide forming rod B48, improves the stability of the pressing bracket B45's movement.

[0043] In some embodiments, the adsorption mechanism B5 includes an adsorption cylinder with its output end facing downwards, and a first suction cup connected to the output end of the adsorption cylinder. Specifically, a certain gap still exists between the bottom cardboard that moves from upstream to below the adsorption mechanism B5 and the first suction cup. To ensure adsorption of the bottom cardboard, the extension of the output end of the adsorption cylinder drives the first suction cup downwards, causing the first suction cup to adhere to the upper surface of the bottom cardboard. Then, a vacuum is created by using a vacuum pump to form a vacuum in the first suction cup, thus securely adsorbing the bottom cardboard.

[0044] In some embodiments, two pressing mechanisms B4 extend along the Y-axis, and each pressing mechanism B4 has two or more adsorption mechanisms B5, which extend along the X-axis. The pressing support B45 is provided with an X-axis forming guide rail B49 extending along the X-axis. The downstream adsorption mechanism B5 is slidably mounted on the X-axis forming guide rail B49 via an X-axis forming slider. Two upstream suction mechanisms A3 are provided. To ensure effective adsorption of the bottom paperboard, two pressing mechanisms B4 are also provided, utilizing multiple adsorption mechanisms B5 to adsorb the bottom paperboard. The X-axis forming guide rail B49 and X-axis forming slider allow the two downstream adsorption mechanisms B5 to move along the X-axis, enabling position adjustment for bottom paperboards of different lengths, thus accommodating the folding and forming of various bottom paperboard lengths.

[0045] In some embodiments, the second frame B1 is provided with a Y-axis forming guide rail B11 extending along the Y-axis direction. A Y-axis forming slider (the Y-axis forming slider is covered by a profile) is slidably disposed on the Y-axis forming guide rail B11. The Y-axis forming slider is fixedly connected to any of the pressing mechanisms B4. The pressing mechanism B4 is connected to a width adjustment drive mechanism B9, which drives the pressing mechanism B4 connected to it to move on the Y-axis forming guide rail B11. In this embodiment, the second frame B1 is provided with a profile, and any pressing mechanism B4 can move along the Y-axis direction, thereby adjusting the adsorption position for bottom paperboards of different widths, making it more adaptable. Specifically, the long side flap B2 located on the same side as the movable pressing mechanism B4 is also disposed on the profile of the pressing mechanism B4, so that when the pressing mechanism B4 is moved, the long side flap B2 on that side can be moved synchronously. Specifically, the width adjustment drive mechanism B9 can be a motor, connecting rod, or lead screw lift.

[0046] In some embodiments, multiple long-side flaps B2 are provided on each side, and the multiple long-side flaps B2 on the same side are on the same horizontal line; the upper part of each long-side flap B2 is bent outward and forms a guide portion B21. The guide portion B21 provides a guiding function for the bottom paperboard, so that the long side of the bottom paperboard can be smoothly folded upward by utilizing the gradually decreasing distance between the two long-side flaps B2.

[0047] In some embodiments, each of the long-side flaps B2 is provided with an oblong hole B22 extending along its width direction, and a locking element is provided in the oblong hole B22. This arrangement ensures that the long-side flaps B2 on the same side are on the same horizontal line, and that each long-side flap B2 can contact the long side of the base plate.

[0048] In some embodiments, the folding mechanism B6 includes a folding cylinder B61 with its output end extending along the Y-axis, and a folding plate B62 fixedly connected to the output end of the folding cylinder B61, the folding plate B62 extending along the Y-axis. Specifically, after the bottom cardboard moves to the side of the folding mechanism B6, the output end of the folding cylinder B61 extends, driving the folding plate B62 to move towards the long side of the bottom cardboard, and folding the corner position of the long side parallel to the short side, facilitating subsequent bonding of the short side with glue at the corner.

[0049] In some embodiments, the second frame B1 is further provided with a forming conveyor mechanism B8, which is located below the long-side flip plate B2 and the short-side flip plate B3, and is used to convey the formed bottom cardboard to the downstream. As described above, in order to improve the bonding effect of the long and short sides, the pressing mechanism B4 will pause for a period of time. After bonding is completed, the pressing mechanism B4 continues to move downward, so that the formed bottom cardboard moves below the long-side flip plate B2 and the short-side flip plate B3. The adsorption mechanism B5 releases the adsorption on the bottom cardboard, and the bottom cardboard falls freely onto the forming conveyor mechanism B8. The forming conveyor mechanism B8 conveys the formed bottom cardboard to the next downstream station.

[0050] Please see Figure 4In some embodiments, the glass feeding device C includes a third frame C1, a conveyor table C4, a glass placement rack C2, and a glass suction mechanism C3. The third frame C1 spans both sides of the conveyor table C4, and the glass placement rack C2 is located beside the third frame C1 and is used to place stacked glass 20. The glass suction mechanism C3 is disposed on the third frame C1 and can reciprocate along the length, width, and height directions of the third frame C1. The glass suction mechanism C3 is used to pick up the glass 20 on the glass placement rack C2 one by one and move it above the conveyor table C4. The conveyor table C4 has a formed bottom cardboard placed on it.

[0051] It should be noted that the glass 20 on the glass placement rack C2 in the attached figure is in an inclined state, while the glass 20 to be loaded is in a flat state.

[0052] The formed bottom cardboard is conveyed to the conveyor table C4. The control mechanism drives the glass suction mechanism C3 to move along the X and Y axes of the third frame C1 to above the glass placement rack C2. Then, it moves down along the Z axis of the third frame C1, using suction to pick up the uppermost glass 20 on the glass placement rack C2. Next, the glass suction machine and glass 20 rise along the Z axis of the third frame C1 and move along the X and Y axes of the third frame C1 until glass 20 is above the conveyor table C4. Subsequently, the glass suction mechanism C3 moves glass 20 down, releasing the suction on glass 20, allowing glass 20 to be placed into the inner cavity of the formed bottom cardboard on the conveyor table C4. Then, the glass suction mechanism C3 resets, and the bottom cardboard containing glass 20 continues to be conveyed downstream through the conveyor table C4.

[0053] Specifically, the X-axis drive, Y-axis drive, and Z-axis drive can adopt the first drive device, second drive device, and third drive device as disclosed in CN113172349A.

[0054] More specifically, a turning table (not shown in the figure) is also provided on the conveyor line between the glass feeding equipment C and the short side folding and bonding equipment D of the face paperboard. The turning table is used to rotate the bottom paperboard conveyed thereon by 90°.

[0055] Please see Figures 5-6In some embodiments, the short-side folding and bonding device D for the face paperboard includes a fourth frame D1, two short-side conveying mechanisms D2 disposed on the fourth frame D1, a long-side blocking mechanism D3, two short-side positioning mechanisms D4, two short-side gluing mechanisms D5, a face paperboard feeding mechanism D6, and two folding mechanisms D7; the short-side conveying mechanism D2 is used to convey the formed bottom paperboard downstream; the long-side blocking mechanism D3 is located downstream of the short-side conveying mechanism D2 and is used to contact the long side of the formed bottom paperboard located downstream; one of the short-side positioning mechanisms D4 is connected to a Y-axis drive mechanism, and the Y-axis drive mechanism is used to drive the short-side positioning mechanism D4 connected thereto and the... The short-side gluing mechanism D5 and the short-side conveying mechanism D2 on the same side as the short-side positioning mechanism D4 move toward the other short-side positioning mechanism D4, and make the two short-side positioning mechanisms D4 contact the corresponding short sides of the formed bottom paperboard respectively; the two short-side gluing mechanisms D5 are used to apply glue to the sidewalls of the corresponding short sides of the formed bottom paperboard when they reciprocate along the X-axis; the face paperboard feeding mechanism D6 is used to move the face paperboard 30 to the upper part of the formed bottom paperboard when it reciprocates along the X-axis; the two folding mechanisms D7 are used to fold the short sides of the face paperboard 30 toward the bottom paperboard respectively, and make the folded edge formed by the face paperboard 30 bond with the glue on the sidewall of the short side of the bottom paperboard.

[0056] Guided by the short-side conveying mechanism D2, the bottom paperboard continuously moves downstream until its long side (downstream / forward) contacts the long-side retaining mechanism D3. The long-side retaining mechanism D3 positions the bottom paperboard, ensuring it is against the edge and that the bottom and top paperboards 30 are conveyed to the correct positions. This prevents the bottom paperboard from being incorrectly positioned when the top and bottom paperboards are closed, thus reducing defects. Next, the two short-side positioning mechanisms D4 move upwards synchronously. Then, under the action of the Y-axis drive mechanism, one side of the short-side positioning mechanism D4, the short-side gluing mechanism D5, and the short-side conveying mechanism D2 move synchronously towards the other side of the short-side positioning mechanism D4 (Y-axis direction) until the short-side positioning mechanisms D4 on both sides abut against the sidewalls of the short sides of the bottom paperboard. The short-side positioning mechanism D4 then completes the bottom paperboard's positioning. The positioning of the short side of the cardboard, in conjunction with the aforementioned long side blocking mechanism D3, ensures the correct placement of the bottom cardboard. Subsequently, the face cardboard feeding mechanism D6 moves along the X-axis / upstream and places the face cardboard 30 on the bottom cardboard. Then, the face cardboard feeding mechanism D6 resets along the X-axis / downstream. The long side blocking mechanism D3 and the short side positioning mechanism D4 reset downwards. Subsequently, under the action of the two short side gluing mechanisms D5, glue is applied to the sidewalls of the short sides of the bottom cardboard. Next, under the action of the two folding mechanisms D7, the edges of the short sides of the face cardboard 30 are folded downwards and come into contact with the glue on the sidewalls of the short sides of the bottom cardboard. The folding mechanism D7 remains in operation, meaning that under the action of external force, the folded edges of the face cardboard 30 are kept in contact with the short sides of the face cardboard 30 for a period of time to ensure the adhesive bonding effect. Finally, all mechanisms are reset, and under the action of the short side conveying mechanism D2, the glued carton is conveyed downstream, waiting for the next bottom board to enter the short side folding station of the face board.

[0057] In some embodiments, a Y-axis slide rail D11 is provided on the fourth frame D1, and a Y-axis slider D12 is slidably disposed on the Y-axis slide rail D11. The Y-axis slider D12 is connected to a sliding frame D13. The Y-axis drive mechanism is used to drive the sliding frame D13 to reciprocate along the Y-axis direction. The short-side positioning mechanism D4 connected to the Y-axis drive mechanism, the short-side gluing mechanism D5 on the same side as the short-side positioning mechanism D4, and the short-side conveying mechanism D2 are all located on the sliding frame D13. The two short-side conveying mechanisms D2 are symmetrically arranged along the X-axis direction of the fourth frame D1, and each short-side conveying mechanism D2 includes multiple rotatable rotating rollers D21 and a conveying drive component for driving the multiple rotating rollers D21 to rotate synchronously. The multiple rotating rollers D21 located on the same side are spaced apart, and the multiple rotating rollers D21 are evenly distributed along the X-axis direction. To ensure the short sides of the bottom cardboard align correctly and that the feeding position of each bottom cardboard aligns with the feeding position of the top cardboard 30, a sliding frame D13 is provided. The corresponding short side aligning mechanism D4, short side conveying mechanism D2, short side gluing mechanism D5, and folding mechanism D7 are mounted on the sliding frame D13, enabling the mechanisms on one side to synchronously move the bottom cardboard towards the mechanisms on the other side. Specifically, the conveying drive can consist of a motor, sprocket, chain, or a motor, drive wheel, and synchronous belt, etc., to make multiple rotating rollers D21 rotate synchronously to transport the bottom cardboard. The conveying drive is a conventional setup and will not be described in detail.

[0058] In some embodiments, the short-side positioning mechanism D4 includes a positioning cylinder D41 with its output end facing upward, a positioning connecting plate D42 connected to the output end of the positioning cylinder D41, and multiple vertical plates D43 fixedly connected to the positioning connecting plate D42; the multiple vertical plates D43 extend vertically upward and are spaced apart, and the positioning cylinder D41 is used to drive the vertical plates D43 to move up and down in the gap formed between adjacent rotating rollers D21. When the short side of the bottom cardboard needs to be aligned, the output end of the alignment cylinder D41 extends upward, driving multiple vertical plates D43 to rise between the rotating rollers D21 via the alignment connecting plate D42, until the upper part of the vertical plates D43 is higher than the top of the rotating rollers D21, i.e., the vertical plates D43 are located beside the short side of the bottom cardboard. Then, during the movement of the sliding frame D13, the alignment of the short sides of the bottom cardboard can be achieved using the vertical plates D43 on both sides. After completing the above operation, the output end of the alignment cylinder D41 retracts downward, driving the multiple vertical plates D43 to move downward, providing clearance for the short side gluing mechanism D5 to apply glue to the short side wall of the bottom cardboard. Specifically, to improve the stability of the alignment connecting plate D42 and the multiple vertical plates D43 during rising and falling, guide rods E4 and sleeves can be provided.

[0059] In some embodiments, both short-side gluing mechanisms D5 include a long-side slide D51 mounted on the sliding frame D13, a glue gun D52 mounted on the long-side slide D51, and an adhesive drive for reciprocating the long-side slide D51 and the glue gun D52 along the X-axis. Specifically, the glue gun D52 is connected to the glue tank via a pipe. During the reciprocating movement of the glue gun D52 along the X-axis, the glue gun D52 can apply glue to the sidewall of the short side of the base cardboard once or twice, depending on the actual situation. That is, the glue gun D52 moves from the upstream position to the downstream position to perform the first glue application, and then returns from the downstream position to the upstream position to perform the second glue application.

[0060] In some embodiments, the adhesive drive includes an X-axis long-side helical rack D55 extending along the X-axis direction, an X-axis long-side gear D54 meshing with the X-axis long-side helical rack D55, and an adhesive drive motor D53 fixedly connected to the X-axis long-side gear D54. The adhesive drive motor D53 is disposed on the long-side slide D51, and the output end of the adhesive drive motor D53 is disposed downward. An X-axis long-side slide rail D56 extending along the X-axis direction is disposed on the fourth frame D1, and the long-side slide D51 is slidably disposed on the X-axis long-side slide rail D56. By utilizing the forward or reverse rotation of the adhesive drive motor D53, the long-side slide D51 is driven to reciprocate along the X-axis direction under the guidance of the X-axis long-side helical rack D55. The above structure can ensure the smooth movement of the long-side slide D51.

[0061] In some embodiments, the folding mechanism D7 includes a folding lifting cylinder D71 with its output end facing downward, a folding lifting pressure plate D72 connected to the output end of the folding lifting cylinder D71, a folding cylinder D73 disposed on the upper surface of the folding lifting pressure plate D72, and a folding plate D75 hinged to the output end of the folding cylinder D73 via a folding hinge seat D74. The folding lifting pressure plate D72 is used to press the face paper 30. The folding cylinder D73 is used to drive the folding plate D75 to contact the edge of the short side of the face paper 30, thereby causing the edge of the short side of the face paper 30 to fold downward. Specifically, after the face paper feeding mechanism D6 completes the feeding operation of the face paper 30, the output end of the folding lifting cylinder D71 extends downward, driving the folding lifting pressure plate D72 to move downward, and providing a downward pressing force for the face paper 30 and the bottom paper, thereby preventing displacement of the face paper 30 and the bottom paper 10. Subsequently, the short-side gluing mechanism D5 operates to apply glue to the sidewall of the short side of the bottom cardboard 10. Then, under the action of the folding cylinder D73, the folding plate D75 acts on the edge of the short side of the face cardboard 30, causing the edge of the short side of the face cardboard 30 to fold downwards, forming a folded edge. During the continuous folding of the folding plate D75, the folded edge remains in contact with the glue on the sidewall of the short side of the bottom cardboard 10, thus ensuring the bonding effect between the short sides of the face cardboard 30 and the bottom cardboard 10. Specifically, to improve the stability of the folding lifting pressure plate D72 and the folding plate D75 during their rise and fall, guide rods and sleeves can be installed.

[0062] In some embodiments, an auxiliary guiding mechanism D8 is also included, located between the two short-side conveying mechanisms D2. The auxiliary guiding mechanism D8 includes an auxiliary support D81 and auxiliary wheels D82 rotatably mounted on the auxiliary support D81. The bottom of the bottom cardboard is supported by the auxiliary guiding mechanism D8 to ensure that the bottom cardboard does not fall out of the gap between the two short-side conveying mechanisms D2 when the short side of the bottom cardboard is aligned.

[0063] In some embodiments, the long-side blocking mechanism D3 includes a blocking cylinder D31 with its output end facing upwards, and a blocking plate D32 fixedly connected to the output end of the blocking cylinder D31. The blocking plate D32 is located downstream of the short-side conveying mechanism D2, and is used to contact the downstream long side of the formed bottom paperboard. Specifically, by extending upwards or retracting downwards at the output end of the blocking cylinder D31, the blocking plate D32 is raised or lowered, so that the upper part of the blocking plate D32 is located on one side of the long side of the bottom paperboard, thereby limiting the downstream long side of the bottom paperboard or satisfying the need to avoid obstruction when the bottom paperboard is conveyed downstream.

[0064] In some embodiments, the paperboard feeding mechanism D6 includes a feeding cylinder D61 with its output end facing downwards, a feeding frame D62 fixedly connected to the output end of the feeding cylinder D61, a plurality of second suction cups D63 disposed on the feeding frame D62, and a feeding drive component D64 for driving the feeding frame D62 to reciprocate along the X-axis direction. Specifically, to facilitate the operation of the next paperboard long-side folding and bonding station, a transport mechanism is also provided between the paperboard feeding mechanism D6 and the fourth frame D1. This transport mechanism is used to transport the carton with the short side of the right paperboard 30 bonded downstream to facilitate the long-side folding process of the paperboard 30. In practical use, the downward extension of the output end of the feeding cylinder D61 drives the feeding frame D62 and the second suction cup D63 mounted on the feeding frame D62 to move downwards, contacting and adsorbing the face paper 30 located below the second suction cup D63. Then, the output end of the feeding cylinder D61 retracts upwards, causing the face paper 30 to rise. Under the action of the feeding drive component D64, the face paper 30 is conveyed towards the bottom paper. Specifically, the feeding drive component D64 can be a motor, gear, or rack and pinion. To improve the smoothness of the movement of the feeding frame D62, a guide rail E55 and a slider can also be provided.

[0065] In some embodiments, a loading lifting frame D65 is also provided below the loading rack D62. The loading lifting frame D65 is used to stack multiple sheets of paperboard 30 to be loaded. The loading lifting frame D65 is connected to a lifting drive component D66, which is used to drive the loading lifting frame D65 to rise to a set height. The loading lifting frame D65 and the lifting drive component D66 are provided to shorten the travel distance of the loading cylinder D61 and the feeding time of the paperboard 30. Specifically, the loading lifting frame D65 is initially positioned at its lowest point. The operator places multiple stacked sheets of paperboard 30 on the loading lifting frame D65, and uses the lifting drive component D66 to drive the loading lifting frame D65 to rise to the set position. Then, in conjunction with the extension or retraction of the output end of the loading cylinder D61, the sheets of paperboard 30 are loaded one by one. More specifically, the lifting drive component D66 can employ a combination of a motor and a lead screw jack. Two lead screw jacks are symmetrically arranged, and each lead screw jack is connected to the corresponding side wall of the loading lifting frame D65, thereby achieving smooth rising or falling of the loading lifting frame D65. In this embodiment, the loading cylinder D61 only has fully extended and fully retracted states. When the loading cylinder D61 descends, allowing the second suction cup D63 to complete the adsorption of the cardboard 30, the lifting drive component D66 operates, driving the loading lifting frame D65 and the multiple cardboard sheets 30 stacked on it to rise a short distance to accommodate the extension and retraction stroke of the loading cylinder D61.

[0066] As can be seen from the above description, the bottom paperboard feeding device A and the top paperboard feeding mechanism D6 are composed of the same structure, which can reduce the complexity of the production line and simplify the production line.

[0067] Please see Figures 7-8 In some embodiments, the long-side folding and bonding device E for the face paperboard includes a fifth frame E1, a plurality of transport rotating rollers E2 extending laterally on the fifth frame E1, a transport rotating drive for driving the plurality of transport rotating rollers E2 to rotate synchronously, two upper guide components E3 disposed above the transport rotating rollers E2 and extending along the length direction of the fifth frame E1, guide rods E4 disposed on the lower surface of the corresponding upper guide components E3, and a long-side gluing mechanism E11 disposed outside the corresponding guide rods E4; the plurality of transport rotating rollers E2 are used to support and cover the bottom paperboard 10 on which the face paperboard 30 is disposed. The material is conveyed downstream; both upper guide components E3 are used to contact the upper surface of the face paper 30, and the two long-side gluing mechanisms E11 are used to apply glue to the sidewalls of the corresponding long side of the formed bottom paper 10; the vertical distance between the two guide rods E4 and the transport rotating roller E2 gradually decreases from upstream to downstream, and the distance between the two guide rods E4 is less than the width of the short side of the face paper 30. The two guide rods E4 are used to fold the long side of the corresponding side of the face paper 30 toward the bottom paper 10, and to bond the folded edge of the face paper 30 to the glue on the sidewall of the long side of the bottom paper 10.

[0068] In practical applications, the rotation of the transport roller E2 provides kinetic energy for the carton with the long side of the face paperboard 30 to be glued downstream. As the carton is gradually conveyed downstream, the guide rods E4 located on both sides of the carton, due to their shape, cause the portions on both sides of the long side of the face paperboard 30 to gradually fold downwards under the external force of the corresponding guide rods E4. Since the purchased face paperboard 30 has pre-formed pre-folding creases on both sides of the long side, these pre-folding creases can easily fold downwards and form folded edges under the external force of the guide rods E4. Before completing the folding of the folded edges, since the long side gluing mechanism E11 has already applied glue to the sidewalls of the long side of the bottom paperboard, the long side of the face paperboard 30 can be folded and glued simultaneously under the continuous rotation of the transport roller E2. Furthermore, the two upper guide components E3 provide installation positions for the guide rods E4 and can contact the upper surface of the face paperboard 30, providing a certain amount of kinetic energy for the downstream conveying of the face paperboard 30.

[0069] In the above-mentioned device, the transport roller E2 is used to transport the carton downstream; the long-side gluing mechanism E11 is used to apply glue to the long side of the bottom cardboard; the guide rod E4 allows the folding lines reserved on the long side of the face cardboard 30 to gradually fold downward as it is gradually transported downstream, and the glue on the long side of the bottom cardboard is used to bond the long side of the face cardboard 30 to the long side of the bottom cardboard; the upper guide component E3 provides an installation position for the guide rod E4 and provides kinetic energy for the carton to be transported downstream; the above-mentioned device has a simple structure and ingenious design.

[0070] Please see Figure 9 In some embodiments, the guide rod E4 includes a first connecting rod body E41, a curved rod body E42, and a second connecting rod body E43. The first connecting rod body E41 extends laterally and is fixedly connected to the two inner sidewalls of the upper guide assembly E3. The upper end of the curved rod body E42 is fixedly connected to the first connecting rod body E41, and the curved rod body E42 gradually slopes downward from upstream to downstream. The upper end of the second connecting rod body E43 is connected to the top inner wall of the upper guide assembly E3, and the lower end of the second connecting rod body E43 is connected to the curved rod body E42. To accommodate the shape of the upper guide frame E31, the first connecting rod E41 is provided. Since the upper end of the bent rod E42 is connected to the first connecting rod E41, and the lower end of the bent rod E42 is a free end, and the bent rod E42 also needs to provide downward pressure to the face paper 30, the lower end of the bent rod E42 needs to be fixed. Therefore, the second connecting rod E43 is provided to prevent the lower end of the bent rod E42 from tilting upward during the downward pressure on the face paper 30, thereby ensuring the downward pressure effect of the pre-folding crease of the face paper 30.

[0071] Please see Figure 8In some embodiments, both upper guide assemblies E3 include an upper guide frame E31 extending along the length of the fifth frame E1 and having an open lower portion, a plurality of upper guide rollers E32 laterally extended on the upper guide frame E31, and an upper guide rotation drive member E33 for driving the plurality of upper guide rollers E32 to rotate synchronously; the upper end of the bent rod E42 passes through the gap formed between two adjacent upper guide rollers E32 and connects to the first connecting rod E41; the upper end of the second connecting rod E43 passes through the gap formed between two adjacent upper guide rollers E32 and connects to the interior of the top of the upper guide frame E31. In this embodiment, the upper guide frame E31 is composed of side frames arranged symmetrically on the left and right, and multiple plates connecting the upper surfaces of the two side frames, which can meet the shape requirements of being hollow and open at the bottom, and can also reduce the weight of the upper guide frame E31. In practical applications, the two ends of the first connecting rod E41 are connected to the inner sidewalls of the two side frames, and the upper end of the second connecting rod E43 is connected to the lower surface of any plate. Specifically, the upper guide rotation drive component E33 can be composed of a guide rotation motor disposed on the upper surface of the board, a drive sprocket disposed on the output end of the guide rotation motor, a driven sprocket disposed at one end of multiple upper guide rollers E32 (the driven sprocket indicated by the upper guide rotation drive component E33 in the figure), and a guide rotation chain wound between the drive sprocket and the driven sprocket. The transport rotation roller E2 contacts the bottom cardboard, and the upper guide roller E32 contacts the top cardboard 30. The two cooperate with each other to achieve clamping and positioning of the carton in the vertical direction, as well as transmission and transportation.

[0072] In some embodiments, the fifth frame E1 is equipped with an upward lifting drive component, which includes an upward lifting motor E341, an upper connecting rod E342 connected to the output end of the upward lifting motor E341, and upper screw lifters E343 that are pulsatorically connected to both ends of the upper connecting rod E342. The two upper screw lifters E343 extend vertically and are respectively fixed to the corresponding outer side wall of the upper guide frame E31 via an upward lifting frame body E36. This configuration allows the upward lifting frame body E36 to drive the upper guide frame E31 to rise or fall, thereby enabling the guide rod E4 to adapt to the bonding of cartons of different thicknesses, i.e., enabling the long-side folding and bonding device E for the faceboard to adapt to the packaging of glass 20 of different thicknesses.

[0073] In some embodiments, the upper surfaces of the two upper guide frames E31 are further provided with upper nut seats E351, and an upper screw E352 is threadedly connected between the two upper nut seats E351. The end of the upper screw E352 is connected to a counter-drive motor (not shown in the figure). The thread on one side of the upper screw E352 is a forward thread, and the thread on the other side is a reverse thread. The upper screw E352 is used to drive the two upper nut seats E351 to move closer or further apart. The counter-drive motor drives the upper screw E352 to rotate. Since the upper screw E352 has two opposing threads, the two upper nut seats E351 can move closer or further apart. The above arrangement allows the two upper guide frames E31 to move closer or further apart, thereby making the long-side folding and bonding device E for faceplates adaptable to the packaging of glass 20 of different widths.

[0074] In some embodiments, the upper surfaces of the two upper guide frames E31 are further provided with upper first guide sleeves E353, and an upper first guide rod E354 is provided between the two upper first guide sleeves E353. The two ends of the upper first guide rod E354 are respectively fixed to the side walls of the upper lifting frame E36. The upper first guide sleeves E353 and the upper first guide rod E354 are provided to improve the stability of movement when the two upper guide frames E31 move closer or further apart.

[0075] In some embodiments, vertically extending upper second guide rods E345 are respectively provided on both sides of the fifth frame E1. Upper second guide sleeves E344 are slidably mounted on the upper second guide rods E345, and the upper second guide sleeves E344 are fixedly connected to the corresponding side walls of the upper lifting frame E36. Similarly, the above configuration is to improve the smoothness of movement of the upper lifting frame E36 during ascent or descent.

[0076] In some embodiments, two side guide components E5 are also included. These two side guide components E5 are respectively inserted into the gap formed by the transport rotating roller E2 and are used to contact the folded edge of the long side of the face paperboard 30. After the long sides of the bottom paperboard and the face paperboard 30 are glued together, the bonding effect of the glue between the long sides of the bottom paperboard and the face paperboard 30 is further improved by the guiding and squeezing action of the side guide components E5 located on both sides of the carton.

[0077] In some embodiments, both side guide assemblies E5 include a lower guide beam E51 extending along the length of the fifth frame E1, multiple side guide rollers E52 extending vertically and rotatably disposed on the upper surface of the lower guide beam E51, a lower lifting frame E53 fixedly connected to the lower surface of the two lower guide beams E51, and a lower lifting drive for driving the lower lifting frame E53 to rise or fall; the upper parts of the multiple side guide rollers E52 are inserted into the gaps formed by the transport rotating rollers E2. During the continuous downstream transport of the carton, the corresponding side guide rollers E52 rotate synchronously, thereby reducing the friction of the carton during transport. Furthermore, the lower lifting drive can drive the multiple side guide rollers E52 to rise or fall synchronously, thus adapting the long-side folding and bonding equipment E for the faceboard to the packaging of cartons / glass 20 of different thicknesses.

[0078] In some embodiments, the lower lifting drive includes a lower lifting motor E541, a lower connecting rod E542 connected to the output end of the lower lifting motor E541, and a lower lead screw lifter E543 that is transmittedly connected to both ends of the lower connecting rod E542; the two lower lead screw lifters E543 extend vertically, and are respectively fixed to the corresponding outer side wall of the lower lifting frame E53; the upper surface of the lower lifting frame E53 is also provided with a guide rail E55 extending along the width direction of the fifth frame E1, and the lower surfaces of the two lower guide beams E51 are respectively provided with sliders, which are slidably disposed on the guide rails E55. Specifically, the lower lifting drive has the same structure as the upper lifting drive, which can reduce the complexity of the long side folding and bonding equipment E for face paperboard, while meeting production requirements. In addition, the guide rails E55 and sliders allow the two lower guide beams E51 to move closer or further apart, enabling them to cooperate with the two upper guide components E3 located above, in order to meet the bonding requirements of cartons of different widths.

[0079] In this diagram, both the upper lifting motor E341 and the lower lifting motor E541 are handwheels.

[0080] In some embodiments, a lower guide sleeve E56 is provided on the lower lifting frame E53, and a lower guide rod E57 is slidably disposed in the lower guide sleeve E56, the lower guide rod E57 extending vertically. Similarly, the above arrangement is used to improve the stability of the lower lifting frame E53 when it rises or falls.

[0081] In this embodiment, the rotation mode of the transport rotating roller E2 and the transport timing belt E61 may include a transport rotating motor, a driving wheel / sprocket connected to the output end of the transport rotating motor, driven wheels / sprockets disposed on multiple transport rotating rollers E2 / transport timing belts E61, and a timing belt / synchronous chain wound between the driving wheel / sprocket and each driven wheel / sprocket. The rotation mode of the transport rotating roller E2 and the second transport roller is the prior art.

[0082] Please see Figure 10 In some embodiments, a plurality of rotatable synchronous transport belts E61 are further provided upstream of the fifth frame E1, and the conveying direction of the plurality of synchronous transport belts E61 is perpendicular to the conveying direction of the transport rotating roller E2; an edge guide rod E62 extending along the length direction of the fifth frame E1 is further provided upstream of any of the upper guide components E3, and the edge guide rod E62 is used to abut against the side wall of any long side of the formed bottom cardboard; the edge guide rod E62 is located above the synchronous transport belts E61. As described above, the upstream of the long side folding and bonding station of the face paperboard 30 is the short side folding and bonding station of the face paperboard 30. The direction of carton conveying is changed by the mutually perpendicular transport timing belt E61 and transport rotating roller E2. The carton conveyed to the end of the short side folding and bonding station of the face paperboard is guided by the side guide rod E62 and the transport timing belt E61 continues to convey the carton downstream, so that the carton can enter the long side folding and bonding station of the face paperboard in the correct position. The carton can enter the transport rotating roller E2 in the correct position and be conveyed to the guide rod E4.

[0083] In summary, this invention integrates the processes of bottom paperboard feeding, bottom paperboard forming, glass 20 feeding, and face paperboard short-side folding and bonding by using a bottom paperboard feeding device A, a bottom paperboard folding and forming device, a glass 20 feeding device, and a face paperboard short-side folding and bonding device D. This achieves continuous production and reduces the problem of inconsistent quality in glass 20 packaging batches caused by human intervention.
