[0030] Preparation: The operator can manually stack multiple bottom paperboards on the loading lifting platform A5. In order to facilitate the operator to load materials, the initial state of the loading lifting platform A5 is located at the bottom of the first frame A1. Then, the loading lifting mechanism A4 operates, driving the loading lifting platform A5 and the bottom paperboard on the loading lifting platform A5 to rise to the set height and then stop operating; then, the loading conveying mechanism A2 drives the suction mechanism A3 located above the bottom paperboard to absorb the bottom paperboard stacked on the top layer, and drives the suction mechanism A3 and the bottom paperboard to move along the X-axis direction (i.e., the downstream direction) to provide bottom paperboard for the next bottom paperboard folding and forming process.

[0031] In some embodiments, the loading conveying mechanism A2 includes an X-axis bevel rack A21 extending along the X-axis direction and arranged on the first frame A1, a conveying gear A22 meshing with the X-axis bevel 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 arranged 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 will drive the conveying gear A22 to rotate synchronously, so that the conveying frame connected to the conveying motor A23 can be synchronously moved along the X-axis direction. Since the conveying frame is fixedly connected to the transverse beam A25, and the suction mechanism A3 is arranged on the transverse beam A25, it can synchronously drive the suction mechanism A3 and the bottom paperboard on the suction mechanism A3 to move along the X-axis direction; when the bottom paperboard is loaded, the entire loading conveying mechanism A2 is reset by the reverse rotation of the conveying motor A23.

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

[0033] In some embodiments, the transverse beams A25 are provided in two numbers, and the two transverse beams A25 are symmetrically arranged along the X-axis direction, and the suction mechanism A3 is provided on the two transverse beams A25, and the suction mechanism A3 on each transverse beam A25 is arranged in multiple numbers along the X-axis direction, and the suction mechanism A3 is a vacuum suction cup. In this embodiment, the bottom paperboard is rectangular, and the long side extends along the X-axis direction, and the short side extends along the Y-axis direction. The two transverse beams A25 are located above the bottom paperboard, and the bottom paperboard is adsorbed by the multiple vacuum suction cups on the two transverse beams A25 to ensure the adsorption effect. Specifically, the transverse beam A25 can move along the Y-axis direction, so that the position of the suction mechanism A3 provided thereon relative to the bottom paperboard can be adjusted, that is, the suction mechanism A3 can load bottom paperboards with different short side lengths.

By utilizing the cooperation of the X-axis loading guide rails A11 and the X-axis loading sliders A12, the conveying frame can be reciprocated stably along the X-axis direction of the first frame A1, and the vibration of the bottom paperboard on the suction mechanism A3 can be avoided.

[0035] In some embodiments, the feeding lifting mechanism A4 includes a feeding lifting motor A41, a feeding connecting rod A42 connected to the output end of the feeding lifting motor A41, and two feeding screw lifters A43 connected to the two ends of the feeding connecting rod A42, the two feeding screw lifters A43 extend along the Y-axis direction, and the two feeding screw lifters A43 are respectively fixed to the outer side walls corresponding to the feeding lifting platform A5. The feeding screw lifters A43 on both sides are driven to run synchronously by a feeding lifting motor A41 to meet the smooth rise or fall of the feeding lifting platform A5. Specifically, the feeding screw lifter A43 is a prior art, which mainly includes a lifter body, a screw and a screw nut, and a meshing worm gear and a worm are arranged in the lifter body, and the screw nut is threadedly connected to the screw.

Similarly, the cooperation between the Z-axis loading guide rail A13 and the Z-axis loading slider A14 can improve the stability of the loading lift platform A5 when it rises or falls.

[0037] In some embodiments, the first frame A1 is further provided with a bottom paperboard in-place sensor A15, which is used to sense the position of the top bottom paperboard placed on the loading lifting platform A5, and the bottom paperboard in-place sensor A15 is electrically connected to the loading lifting motor A41 through a control mechanism. Specifically, the loading lifting platform A5 and a plurality of stacked bottom paperboards rise synchronously, and after the position of the top bottom paperboard is captured by the bottom paperboard in-place sensor A15, the control mechanism drives the loading lifting motor A41 to stop running, and then the output end of the loading conveying cylinder A26 extends downward to drive the suction mechanism A3 to move downward and absorb the top bottom paperboard, and then the output end of the loading conveying cylinder A26 contracts upward to drive the suction mechanism A3 and the bottom paperboard to rise, and under the action of the loading conveying mechanism A2, they move in the direction of the X axis.

[0038] In some embodiments, the first frame A1 is further provided 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 moving stroke of the loading lifting platform A5, and the bottom paperboard in-place sensor A15 is located between the upper limit sensor A18 and the lower limit sensor A19. The two limit sensors are provided to limit the moving stroke of the loading lifting platform A5, thereby ensuring the movement accuracy of the loading lifting platform A5 and the bottom paperboard stacked on the loading lifting platform A5 in the Z-axis direction. Specifically, the positions of the upper limit sensor A18, the lower limit sensor A19, and the bottom paperboard in-place sensor A15 relative to the first frame A1 can be adjusted, so that the operation of the bottom paperboard feeding device is more accurate, and the bottom paperboard feeding device can feed bottom paperboards of different thicknesses by adjusting the height of each sensor relative to the first frame A1.

[0040] After loading, the bottom paper board enters the folding and forming process, and is transported to the bottom of the adsorption mechanism B5 by the feeding conveying mechanism A2 and the suction mechanism A3 located upstream, and the adsorption mechanism B5 is driven to move downward by the pressing mechanism B4, and the adsorption mechanism B5 is brought into contact with the upper surface of the bottom paper board. After the bottom paper board is adsorbed, the feeding conveying mechanism A2 and the suction mechanism A3 located upstream are reset (i.e., move in the upstream direction); subsequently, the pressing mechanism B4, the adsorption mechanism B5 and the bottom paper board continue to move downward until the long side of the bottom paper board contacts the long side flap B2, and under the action of the long side flap B2 , so that the long side with pre-creases is folded upwards; then the bottom paperboard continues to move down to the side of the glue spraying mechanism B7 and the folding mechanism B6, the glue spraying mechanism B7 and the folding mechanism B6 are operated, the four corners of the long side are sprayed with glue and the long side is folded again, and the folding mechanism B6 is reset after the above operations are completed; then, the pressing mechanism B4 continues to move down, and the short side with pre-creases is folded upwards by using the short side flap B3, so that the folded short side is bonded to the four corners of the long side sprayed with glue. In order to improve the bonding effect, the pressing mechanism B4 will pause at the position of the long side flap B2 and the short side flap B3 and then reset upwards. Specifically, the short side flap B3 in this embodiment is a profile.

[0041] In some embodiments, the pressing mechanism B4 includes a forming mounting seat B41 disposed on the second frame B1, a pressing motor B42 disposed on the forming mounting seat B41, a pressing gear B43 drivingly 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 is vertically extended, 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 are synchronously raised or lowered.

[0042] In some embodiments, the pressing bracket B45 is provided with a Z-axis forming guide rail B46 extending in the direction of the Z-axis, and the forming mounting seat B41 is provided with a Z-axis forming slider slidably connected to the Z-axis forming guide rail B46; the second frame B1 is also provided with a guide forming cylinder B47, and a guide forming rod B48 runs through the guide forming cylinder B47, and the lower end of the guide forming rod B48 is fixedly connected to the pressing bracket B45. Since the format of the bottom paperboard of this embodiment is large, the length of the pressing bracket B45 is long, that is, the volume is large, and the cooperation of the Z-axis forming guide rail B46 and the Z-axis forming slider, the guide forming cylinder B47 and the guide forming rod B48 is used to improve the moving stability of the pressing bracket B45.

[0043] In some embodiments, the adsorption mechanism B5 includes an adsorption cylinder with an output end facing downward, and a first suction cup connected to the output end of the adsorption cylinder. Specifically, there is still a certain gap between the bottom paperboard moving from the upstream to the bottom of the adsorption mechanism B5 and the first suction cup. In order to ensure the adsorption of the bottom paperboard, the first suction cup is driven downward by the extension of the output end of the adsorption cylinder, so that the first suction cup is attached to the upper surface of the bottom paperboard, and then the first suction cup is vacuumed by a vacuum device, so that the bottom paperboard can be firmly adsorbed.

[0044] In some embodiments, the pressing mechanism B4 is provided with two extending in the Y-axis direction, the adsorption mechanism B5 on each pressing mechanism B4 is provided with two or more, and the two or more adsorption mechanisms B5 extend in the X-axis direction; the pressing bracket B45 is provided with an X-axis forming guide rail B49 extending in the X-axis direction, and the adsorption mechanism B5 located downstream is slidably provided on the X-axis forming guide rail B49 through an X-axis forming slider. The upstream suction mechanism A3 is provided with two. In order to ensure the adsorption effect on the bottom paperboard, the pressing mechanism B4 is also provided with two, and the bottom paperboard is adsorbed by multiple adsorption mechanisms B5. By providing the X-axis forming guide rail B49 and the X-axis forming slider, the two adsorption mechanisms B5 located downstream can move in the X-axis direction, and the positions of the bottom paperboards of different lengths can be adjusted to adapt to the folding forming of bottom paperboards of various 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, and a Y-axis forming slider (the Y-axis forming slider is blocked by the profile) is slidably provided on the Y-axis forming guide rail B11, and the Y-axis forming slider is fixedly connected to any of the pressing mechanisms B4; the pressing mechanism B4 is connected to the width adjustment driving mechanism B9, and the width adjustment driving mechanism B9 is used to drive the pressing mechanism B4 connected thereto to move on the Y-axis forming guide rail B11.

Specifically, the long side flap B2 located on the same side as the movable pressing mechanism B4 is also provided on the profile of the pressing mechanism B4, so that when the pressing mechanism B4 is moved, the long side flap B2 on this side can be driven to move synchronously. Specifically, the width adjustment driving mechanism B9 can be in the form of a motor, a connecting rod, and a screw lifter.

[0046] In some embodiments, the long edge flaps B2 are provided in plurality on each side, and the plurality of long edge flaps B2 on the same side are on the same horizontal line; the upper portion of each long edge flap B2 is bent outward and forms a guide portion B21. The guide portion B21 can provide a guide for the bottom paper board, so that the long edge of the bottom paper board can be smoothly folded upward by using the long edge flaps B2 on both sides with a gradually decreasing distance.

[0047] In some embodiments, each of the long edge flaps B2 is provided with a waist-shaped hole B22 extending along its width direction, and a locking member is provided in the waist-shaped hole B22. Through the above arrangement, it is ensured that the long edge flaps B2 on the same side are located on the same horizontal line, and that each long edge flap B2 can contact the long edge of the bottom paper board.

[0048] In some embodiments, the folding mechanism B6 includes a folding cylinder B61 whose output end extends along the Y-axis direction, and a folding plate B62 fixedly connected to the output end of the folding cylinder B61, and the folding plate B62 is extended along the Y-axis direction. Specifically, after the bottom paperboard 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 toward the long side of the bottom paperboard, and folds the corner position of the long side to be parallel to the short side, providing convenience for the subsequent bonding of the short side through the glue at the corner.

The long-side blocking mechanism D3 positions the bottom paperboard so that the bottom paperboard is close to the edge, ensuring that the bottom paperboard and the face paperboard 30 are conveyed to the set position in the correct position, thereby avoiding that when the face paperboard 30 is covered with the bottom paperboard, the incorrect position of the bottom paperboard affects the covering of the face paperboard 30 with the bottom paperboard, thereby reducing the production of defective products; then, the two short-side positioning mechanisms D4 move upward synchronously, and then, under the action of the Y-axis driving mechanism, the short-side positioning mechanism D4, the short-side gluing mechanism D5 and the short-side conveying mechanism D2 on one side are synchronously moved toward the direction of the short-side positioning mechanism D4 on the other side (in the Y-axis direction), until the short-side positioning mechanisms D4 on both sides respectively contact the side walls of the short sides of the bottom paperboard, and the bottom is realized through the short-side positioning mechanisms D4.

Specifically, the conveying drive member can be composed of a motor, a sprocket, a chain, or a motor, a transmission wheel, a synchronous belt, etc., so that multiple rotating rollers D21 rotate synchronously to realize the transportation of the bottom paperboard. The conveying drive member is a conventional setting and will not be described in detail.

When the short side of the bottom paperboard needs to be positioned, the output end of the positioning cylinder D41 extends upward, and drives the plurality of vertical plates D43 to rise between the rotating rollers D21 through the positioning connecting plate D42, until the upper part of the vertical plate D43 is higher than the top of the rotating roller D21, that is, the vertical plate D43 is located beside the short side of the bottom paperboard, and then during the movement of the sliding frame D13, the vertical plates D43 on both sides can be used to position the short sides of the bottom paperboard.

Specifically, when the face paper board feeding mechanism D6 completes the feeding operation of the face paper board 30, the output end of the folding lifting cylinder D71 extends downward, drives the folding lifting plate D72 to move downward, and provides a downward pressure to the face paper board 30 and the bottom paper board, thereby preventing the face paper board 30 and the bottom paper board 10 from displacement. Then the short edge gluing mechanism D5 operates to glue the side wall of the short edge of the bottom paperboard 10; then, under the action of the folding cylinder D73, the folding plate D75 acts on the edge position of the short edge of the face paperboard 30, and drives the edge position of the short edge of the face paperboard 30 to fold downward to form a folded edge. During the continuous flipping of the folding plate D75, the folded edge is always in contact with the glue on the side wall of the short edge of the bottom paperboard 10, thereby ensuring the bonding effect of the short edge of the face paperboard 30 and the short edge of the bottom paperboard 10.

Specifically, the upward extension or downward contraction of the output end of the material blocking cylinder D31 drives the material blocking plate D32 to rise or fall, so that the upper part of the material blocking plate D32 is located on one side of the long side of the bottom paperboard, thereby realizing the limitation of the long side of the bottom paperboard located downstream, or satisfying the avoidance when the bottom paperboard is conveyed in the downstream direction.

[0065] In some embodiments, a loading lifting frame D65 is further provided below the loading frame D62, and the loading lifting frame D65 is used to stack multiple face paperboards 30 to be loaded; the loading lifting frame D65 is connected to a lifting drive D66, and the lifting drive D66 is used to drive the loading lifting frame D65 to rise to a set height. In order to shorten the moving stroke of the loading cylinder D61 and shorten the suction time of the face paperboard 30, the loading lifting frame D65 and the lifting drive D66 are provided. Specifically, the initial position of the loading lifting frame D65 is located at the lowest point. The operator places the stacked multiple face paperboards 30 on the loading lifting frame D65, and uses the lifting drive D66 to drive the loading lifting frame D65 to first rise to the set position, and then cooperate with the extension or contraction of the output end of the loading cylinder D61 to meet the feeding of the face paperboards 30 one by one.

The two guide rods E4 are respectively used to fold the long sides of the corresponding sides of the face paperboard 30 toward the bottom paperboard 10, and make the folded edges formed by the face paperboard 30 bond with the glue on the long side walls of the bottom paperboard 10.

[0068] In actual application, the rotation of the transport rotating roller E2 provides kinetic energy for the carton to be glued on the long side of the face paperboard 30 to be transported downstream. In the process of gradually transporting the carton downstream, the guide rods E4 located on both sides of the carton, due to the shape of the guide rods E4, make the parts on both sides of the long side of the face paperboard 30 gradually fold downward under the external force of the corresponding guide rods E4. Since the purchased face paperboard 30 will form pre-folding marks on both sides of the long side in advance, under the external force of the guide rods E4, the pre-folding marks can be easily folded downward and form a folding edge. Before the folding of the folding edge is completed, since the long side gluing mechanism E11 has glued the side wall of the long side of the bottom paperboard, the long side of the face paperboard 30 can be folded and glued at the same time under the continuous rotation of the transport rotating roller E2. In addition, the two upper guide components E3 are used to provide an installation position for the guide rods E4 on the one hand, and can contact the upper surface of the face paperboard 30 on the other hand, and provide a certain amount of kinetic energy for the face paperboard 30 to be transported downstream.

In order to adapt to the shape of the upper guide frame E31, the first connecting rod body E41 is provided. Since the upper end of the bending rod body E42 is connected to the first connecting rod body E41, the lower end of the bending rod body E42 is a free end, and the bending rod body E42 also needs to provide downward pressure for the surface cardboard 30, so the lower end of the bending rod body E42 needs to be fixed, so the second connecting rod body E43 is provided to prevent the lower end of the bending rod body E42 from warping up during the process of pressing down on the opposite cardboard 30, thereby ensuring the downward pressure effect of the pre-folding mark of the opposite cardboard 30.
