Description

Box making machine and octagonal box preparation method Technical Field

[0001] This invention relates to the field of box-making technology, and in particular to a box-making machine and a method for preparing octagonal boxes. Background Technology

[0002] In the existing market, box-making machines used to prepare multi-corner boxes formed by a base plate and side plates generally adopt a horizontal structure. During preparation, the side plates after being sprayed with glue need to be erected to one side of the mold. The mold moves horizontally towards the forming station with the side plates. One of the side plates of the side plates needs to be fixed to one of the front sides of the mold first. Then, the base plate is moved up and attached to the lower surface of the mold. At the same time, the bottom edge of the side plate is aligned with the perimeter of the base plate. Finally, multiple circumferential pressure plates move inward horizontally to press the multiple side plates of the side plates onto the base plate.

[0003] However, it has the following problems:

[0004] (a) During molding, when the base plate is moved up and attached to the lower surface of the mold, interference may easily occur between the base plate and the side plate that has been fixed in advance, causing damage to the side plate or the base plate, or scraping the glue on the bottom edge of the side plate, causing the glue to overflow onto the mold, resulting in problems such as the box body being difficult to demold and the side plate not being properly attached to the base plate.

[0005] (ii) Since the side panel needs to be erected, it needs to be bent horizontally during molding. When the mold moves with the side panel, the two ends of the side panel hang down under the action of gravity, which can easily cause tearing of the side groove of the side panel. Summary of the Invention

[0006] In order to overcome at least one of the defects of the prior art, the present invention provides a box-making machine for preparing a multi-corner box formed by a base plate and a side plate. It adopts a vertical structure and prepares the multi-corner box by loading the base plate first and then pressing the side plate together. The machine has good bonding effect and high yield.

[0007] The technical solution adopted by this invention to solve its problem is:

[0008] A box-making machine for producing a polygonal box formed by a base plate and side plates, characterized in that it comprises: a side plate ejection module for ejecting side plates, a bottom edge gluing module for applying glue to the bottom edge of the side plates, a bottom plate ejection module for ejecting the base plate, and a forming module for bonding the base plate and side plates; wherein,

[0009] The molding module includes a cavity unit and a mold unit for loading the base plate. The mold unit is located above the cavity unit and moves up and down in the vertical direction.

[0010] The output end of the enclosure panel ejection module is connected to the input end of the bottom edge gluing module, and the output end of the bottom edge gluing module is connected to the input end of the cavity unit. The bottom plate ejection module is located on one side of the mold unit and is used to lift the bottom plate and transport it to the mold unit. The mold unit can press the bottom plate down toward the enclosure panel.

[0011] The box-making machine provided by this invention discharges the side panels through a side panel discharge module, applies adhesive to the bottom edge of the side panels through a bottom edge gluing module, discharges the bottom panel through a bottom panel discharge module, and bonds the bottom panel and side panels into a box through a forming module. During the bonding process, the bottom panel is upright while the side panels are flat. The bottom panel is first loaded onto the mold unit, and then the mold unit moves the bottom panel downwards and presses down on the side panels to bond the bottom edge of the bottom panel to the side panels. In this way, the multi-corner box is prepared by loading the bottom panel first and then pressing the side panels together, which solves the problem of interference between the bottom panel and the side panels, solves the problem of glue overflow, and achieves good bonding effect. On the other hand, since the bottom panel is upright and the side panels are flat, it can solve the problem of tearing of the side grooves of the side panels caused by the downward drooping of the two ends of the side panels under the action of gravity when they are bent horizontally, thereby improving the yield rate.

[0012] Furthermore, the mold unit includes a first slide, a mold, and a negative pressure device for adsorbing the base plate. The mold is disposed on the first slide, which is slidably disposed on a frame. A first driving device drives the first slide to move the mold. The negative pressure device is located on the end face of the mold corresponding to the base plate, and the end face is arranged vertically.

[0013] Furthermore, the first slide includes a connecting plate, a hollow tube, a first end cap, a second end cap, an air pipe connector, and a fixing sleeve. The first end cap and the second end cap are respectively sealed at both ends of the hollow tube. The air pipe connector is located at the first end cap, the negative pressure device is located at the second end cap, and the fixing sleeve is connected to the connecting plate. One end of the hollow tube connected to the first end cap is inserted into the fixing sleeve. The connecting plate is provided with a clearance hole corresponding to the hollow tube.

[0014] Furthermore, a shallow groove is formed inward on the end face to create a protrusion around the periphery of the end face, and the negative pressure device is located in the shallow groove.

[0015] Furthermore, the molding module also includes a support unit for clamping the enclosure plate to the mold unit. The support unit is located below the mold unit, and the mold unit presses down to pre-press the enclosure plate onto the support unit. The support unit is configured to move with the mold unit toward the cavity unit.

[0016] Furthermore, the supporting unit includes a second slide and two pallet assemblies for clamping the enclosure. The two pallet assemblies are spaced apart on the second slide, which is slidably mounted on a frame. A second drive device drives the second slide to move the two pallet assemblies.

[0017] Furthermore, the pallet assembly includes a first mounting base, a first pallet, a second pallet, and a third driving device. The first mounting base is disposed on the second slide, the first pallet is disposed on the first mounting base, the second pallet is rotatably disposed on the first pallet or the first mounting base, and the third driving device drives the second pallet to rotate relative to the first pallet so that an angle is formed between the second pallet and the first pallet for the corresponding corner of the enclosure.

[0018] Furthermore, the molding module also includes a pressing unit for pressing the enclosure, the pressing unit moving horizontally toward or away from the mold unit to press a portion of the bottom edge of the enclosure with a portion of the periphery of the base plate.

[0019] Furthermore, the pressing unit includes a third slide and a pressing roller for pressing the enclosure. The third slide is slidably mounted on a frame, and the pressing roller is rotatably mounted on the third slide. A fifth driving device drives the third slide to move the pressing roller.

[0020] Furthermore, the molding module also includes two swing arm units for supporting the baffle, which are located on both sides of the input end of the cavity unit. The swing arm units are configured to flip relative to the mold unit to bend the baffle upward.

[0021] Furthermore, the swing arm unit includes a rotating base and a swing plate. The rotating base is rotatably mounted on a frame, and the swing plate is mounted on the rotating base. A sixth drive device drives the rotating base to cause the swing plate to swing.

[0022] Furthermore, the molding module also includes a demolding unit for demolding the prepared polygonal box and a flipping unit for flipping the prepared polygonal box. The demolding unit is located at the output end of the cavity unit, and the flipping unit is located at the output end of the cavity unit.

[0023] Furthermore, it also includes a beveled edge gluing device for applying glue to the beveled edge of the enclosure and a back adhesive application device for applying glue to the back of the enclosure, both of which are located at the output end of the enclosure discharge module.

[0024] Furthermore, the bottom edge gluing module includes a clamping and pulling device, a bottom edge gluing device, and a transfer device. The clamping and pulling device is used to clamp one end of the enclosure and pull the enclosure to move downwards towards the transfer device. The transfer device is used to transport the gluing-completed enclosure to the cavity unit.

[0025] Based on the same concept, this invention also discloses a method for preparing a multi-faceted box, applied to the box-making machine described above, comprising:

[0026] The enclosure is unloaded and conveyed to the bottom edge gluing module;

[0027] In the bottom edge gluing module, glue is applied to the bottom edge of the enclosure and then conveyed to the input end of the cavity unit in the molding module.

[0028] After the base plate is unloaded, it is erected and conveyed to the mold unit in the forming module;

[0029] After the base plate and the surrounding plate are both conveyed to the forming module, the box is unloaded.

[0030] In the molding module, the mold unit moves the base plate downwards and presses down on the surrounding plate to bond the lower edge of the base plate to the surrounding plate.

[0031] In summary, the box-making machine and multi-corner box preparation method provided by the present invention have the following technical effects:

[0032] 1) The enclosure panel is ejected via the enclosure panel ejection module, the bottom edge of the enclosure panel is glued via the bottom edge gluing module, the bottom plate is ejected via the bottom plate ejection module, and the bottom plate and enclosure panel are bonded together to form a box via the forming module. During the bonding process, the bottom plate is upright while the enclosure panel is flat. The bottom plate is first loaded onto the mold unit, and then the mold unit moves the bottom plate downwards and presses down on the enclosure panel to bond the bottom edge of the bottom plate to the enclosure panel. In this way, the multi-corner box is manufactured by loading the bottom plate first and then pressing the enclosure panel together, which solves the problem of interference between the bottom plate and the enclosure panel, solves the problem of glue overflow, and achieves good bonding effect. On the other hand, since the bottom plate is upright and the enclosure panel is flat, it can solve the problem of tearing of the side groove of the enclosure panel caused by the two ends of the enclosure panel drooping downwards under the action of gravity when the enclosure panel is bent horizontally, thus improving the yield rate.

[0033] 2) The base plate is adsorbed onto the end face of the mold by a negative pressure device, so that the base plate can move together with the mold. Its overall structure is simple and low cost.

[0034] 3) The supporting unit can be used to clamp the side panel to the mold unit facing the cavity unit, so that the front of the polygonal box is glued under the action of the mold unit and the supporting unit. As the mold unit and the supporting unit continue to move towards the cavity unit, the side of the polygonal box is glued in the cavity unit. The pressing unit moves towards the mold unit, so that the rear of the polygonal box is glued under the action of the pressing unit. Its overall structure is simple and the operation is concise.

[0035] 4) The swing arm unit can be used to support and bend the side panel. The swing arm unit can also be used to complete the initial bonding of the sides of the polygonal box, and then complete the final bonding in the cavity unit. It can be better suited for the preparation of polygonal boxes made of MDF material.

[0036] 5) Apply adhesive to the beveled edge of one end of the enclosure using the beveled edge gluing device, and apply tape to the back of one end of the enclosure using the back adhesive applicator. This provides more adhesion for the preparation of the multi-corner box, improves the strength of the multi-corner box, and prevents the multi-corner box from cracking due to the glue not drying or secondary handling.

[0037] 6) In the bottom edge gluing module, the panel is moved by pulling, which makes it easy to check whether the panel is broken and avoids the panel from arching during the movement, thus facilitating the bottom edge gluing operation. Attached Figure Description

[0058] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0059] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0061] Referring to Figure 1, the present invention discloses a box-making machine for preparing a multi-cornered box formed by a base plate and a side plate. The box-making machine includes: a side plate feeding module 2 for feeding the side plate 6, a bottom edge gluing module 3 for gluing the bottom edge of the side plate 6, a bottom plate feeding module 4 for feeding the base plate 5, and a forming module 1 for bonding the base plate 5 and the side plate 6.

[0062] The molding module 1 includes a cavity unit 11 and a mold unit 12 for loading the base plate 5. The mold unit 12 is located above the cavity unit 11 and moves up and down in the vertical direction. The output end of the side panel discharge module 2 is connected to the input end of the bottom edge gluing module 3. The output end of the bottom edge gluing module 3 is connected to the input end of the cavity unit 11. The base plate discharge module 4 is located on one side of the mold unit 12 and is used to lift the base plate 5 and transport it to the mold unit 12. The mold unit 12 can press the base plate 5 down toward the side panel 6.

[0063] In the above solution, the enclosure panel 6 is ejected through the enclosure panel ejection module 2, the bottom edge of the enclosure panel 6 is glued through the bottom edge gluing module 3, the bottom plate 5 is ejected through the bottom plate ejection module 4, and the bottom plate 5 and enclosure panel 6 are bonded together to form a box through the forming module 1. During the bonding process, the bottom plate 5 is upright while the enclosure panel 6 is flat. The bottom plate 5 is first loaded onto the mold unit 12, and then the mold unit 12 carries the bottom plate 5 downward and presses down on the enclosure panel 6 so that the lower edge of the bottom plate 5 is bonded to the enclosure panel 6. In this way, the multi-corner box is prepared by loading the bottom plate 5 first and then pressing the enclosure panel 6, which solves the problem of interference between the bottom plate 5 and the enclosure panel 6, solves the problem of glue overflow, and achieves good bonding effect. On the other hand, since the bottom plate 5 is upright while the enclosure panel 6 is flat, it can solve the problem of tearing of the side groove of the enclosure panel caused by the two ends of the enclosure panel 6 hanging down under the action of gravity when it is bent horizontally, thus improving the yield rate.

[0064] Preferably, the box-making machine further includes an oblique edge gluing device 7 and a back adhesive applicator 8. Both the oblique edge gluing device 7 and the back adhesive applicator 8 are located at the output end of the side panel discharge module 2. During the output of the side panel 6 from the side panel discharge module 2, the oblique edge gluing device 7 applies glue to the oblique edge of one end of the side panel 6. After the side panel 6 stops, the back adhesive applicator 8 applies adhesive tape to the back of one end of the side panel 6. More preferably, the oblique edge gluing device 7 and the back adhesive applicator 8 are arranged adjacent to each other to perform both oblique edge gluing and back adhesive tape application on the same end of the side panel 6. This provides greater bonding force, improves the strength of the multi-cornered box, and prevents cracking caused by undried glue or secondary handling.

[0065] It should be noted that the inventive concept of this invention does not lie in the specific structure of the side panel ejection module 2, the bottom edge gluing module 3, the bottom plate ejection module 4, the beveled edge gluing device 7, and the back adhesive applicator 8. Therefore, this invention does not limit the specific structure of the side panel ejection module 2, the bottom edge gluing module 3, the bottom plate ejection module 4, the beveled edge gluing device 7, and the back adhesive applicator 8, as long as they meet their respective functions. The side panel ejection module 2, the bottom edge gluing module 3, the bottom plate ejection module 4, the beveled edge gluing device 7, and the back adhesive applicator 8 can refer to the relevant structures in existing multi-functional box-making machines, and this invention will not elaborate on them.

[0066] As an example, referring to Figure 2, the bottom edge gluing module 3 includes a clamping and pulling device 31, a bottom edge gluing device 32, and a transfer device 33. The clamping and pulling device 31 is used to clamp one end of the enclosure plate 6 and pull the enclosure plate 6 downwards towards the transfer device 33; while the clamping and pulling device 31 pulls the enclosure plate 6, the bottom edge gluing device 32 applies glue to the bottom edge of the enclosure plate 6; the transfer device 33 is used to transport the enclosure plate 6, which has completed bottom edge gluing, oblique edge gluing, and backside gluing, to the molding module 1. Specifically, the transfer device 33 transports the enclosure plate 6 between the mold unit 12 and the support unit 13.

[0067] The enclosure panel 6 is moved by pulling, which makes it easier to check whether the enclosure panel 6 is broken and avoids the enclosure panel 6 from arching during the movement, and facilitates the application of glue to the bottom edge.

[0068] This embodiment does not limit the specific structure of the clamping device 31, the bottom edge gluing device 32, and the transfer device 33. Any currently known structure can be used to achieve its corresponding function.

[0069] As a further example, referring to Figure 3, the clamping and pulling device 31 includes a fourth mounting base 311, a fifth slide block 312, a lower clamping jaw 313, an upper clamping jaw 314, a cylinder 315, and a tenth driving device 316. The fifth slide block 312 is slidably mounted on the fourth mounting base 311 via a slide rail. The lower clamping jaw 313 is fixed to the fifth slide block 312. The upper clamping jaw 314 is rotatably connected to the lower clamping jaw 313. The two ends of the cylinder 315 are respectively connected to the lower clamping jaw 313 and the upper clamping jaw 314. The cylinder 315 drives the upper clamping jaw 314 to rotate to clamp the enclosure 6. The tenth driving device 316 drives the fifth slide block 312 to slide to pull the enclosure 6 below the transfer device 33. The tenth driving device 316 can be a motor driving a two-phase transmission belt assembly to drive the fifth slide block 312 to slide relative to the fourth mounting base 311; or, the tenth driving device 316 can be other known driving devices. This invention does not specifically limit the tenth driving device 316.

[0070] Referring to Figures 4 and 5, in this embodiment, the molding module 1 further includes: a support unit 13, a pressing unit 14, a swing arm unit 15, a demolding unit 16, and a box-flipping unit 17. The cavity unit 11, the mold unit 12, the support unit 13, the pressing unit 14, the swing arm unit 15, the demolding unit 16, and the box-flipping unit 17 can all be installed on the frame 18.

[0071] It should be noted that the frame 18 may include multiple sub-frames, which may be independent of each other or connected. Each unit may be installed on different sub-frames, or multiple units may be installed together on the same sub-frame. That is, frame 18 is a general term used to complete the relative positioning and installation of each unit; it is not limited to all units being installed on a specific overall frame. Furthermore, some relatively independent units may be installed directly on the ground. For example, mold unit 12 and support unit 13 may be installed simultaneously on one sub-frame, while cavity unit 11, pressing unit 14, swing arm unit 15, and demolding unit 16 may be installed simultaneously on another sub-frame, and box-flipping unit 17 may also be installed directly on the ground. For ease of description and simplification, this embodiment will uniformly describe that cavity unit 11, mold unit 12, support unit 13, pressing unit 14, swing arm unit 15, demolding unit 16, and box-flipping unit 17 are all installed on frame 18.

[0072] Referring to Figures 4 and 5, in this embodiment, the supporting unit 13 is used to clamp the surrounding plate 6 to the mold unit 12. The supporting unit 13 is located below the mold unit 12 and is configured to move with the mold unit 12 toward the cavity unit 11, that is, the supporting unit 13 can also move up and down in the vertical direction; the pressing unit 14 is used to press the surrounding plate 6. The pressing unit 14 moves in the horizontal direction toward or away from the mold unit 12 to press a part of the bottom edge of the surrounding plate 6 with a part of the periphery of the base plate 5; the swing arm unit 15 is used to support the surrounding plate 6. The two swing arm units 15 are located on both sides of the input end of the cavity unit 11. The swing arm units 15 are configured to flip relative to the mold unit 12 to bend the surrounding plate 6 upward; the demolding unit 16 is used to demold the prepared polygonal box. The demolding unit 16 is located at the output end of the cavity unit 11; the flipping unit 17 is used to flip the prepared polygonal box. The flipping unit 17 is located at the output end of the cavity unit 11.

[0073] It should be noted that the base plate 5 and the surrounding plate 6 can be made of cardboard or MDF. The multi-angled box can specifically be a pentagonal box, a hexagonal box, an octagonal box, etc. For ease of understanding, this invention will be specifically described using an octagonal box made of MDF as an example. In this case, the swing arm unit 15 can also have another function: after bending the surrounding plate 6, the swing arm unit 15 can also clamp the surrounding plate 6 onto the mold unit 12 to press a part of the bottom edge of the surrounding plate 6 with a part of the periphery of the base plate 5.

[0074] It should be noted that in other embodiments, when preparing an octagonal box made of cardboard, since the cardboard partition 6 does not need to be bent in advance, the swing arm unit 15 is not required. Instead, the partition 6 can be constrained by the input end of the cavity unit 11 for bending. Of course, having the swing arm unit 15 is preferable.

[0075] In summary, in the molding module 1, firstly, the base plate 5 is loaded onto the mold unit 12, and the surrounding plate 6 can be moved between the mold unit 12 and the supporting unit 13. At this time, both the supporting unit 13 and the swing arm unit 15 can support the side of the surrounding plate 6 away from the mold unit 12. Specifically, both the supporting unit 13 and the swing arm unit 15 can support the bottom surface of the surrounding plate 6. Then, the mold unit 12 moves towards the cavity unit 11 with the base plate 5, pre-pressing the surrounding plate 6 onto the supporting unit 13 to achieve initial clamping of the surrounding plate 6. At this time, the supporting unit 13 can press the bottom edge of the surrounding plate 6 near the middle position to the lower periphery of the base plate 5, so that the front edge of the polygonal box is bonded under the action of the mold unit 12 and the supporting unit 13. Then, the mold unit 12 and The supporting unit 13 continues to move toward the cavity unit 11 (i.e., continues to descend), while the swing arm unit 15 flips to bend the surrounding plate 6 and clamps the surrounding plate 6 on both sides of the mold unit 12, pressing a portion of the bottom edge of the surrounding plate 6 with a portion of the periphery of the base plate 5. This allows the sides of the polygonal box to be initially bonded under the action of the swing arm unit 15, at which point the lower half of the polygonal box is roughly formed. Finally, as the mold unit 12 and the supporting unit 13 continue to move, the sides of the polygonal box are completely bonded in the cavity unit. At the same time, the pressing unit 14 moves toward the mold unit 12, allowing the rear of the polygonal box to be bonded under the action of the pressing unit 14. This achieves the preparation of the polygonal box by first loading the base plate 5 and then pressing the surrounding plate 6. Its overall structure is simple and the operation is concise.

[0076] Referring to Figure 6, in this embodiment, the cavity unit 11 includes two sets of opposing cavity components 111 and a cavity 112 formed by the two cavity components 111 to accommodate the prepared polygonal box. The cavity component 111 includes a fourth slide 1111, two forming cavity pillars 1112 and a seventh driving device 1113. The fourth slide 1111 is slidably mounted on the frame 18, and the two forming cavity pillars 1112 are spaced apart on the fourth slide 1111. Specifically, the fourth slide 1111 is slidably mounted on the frame 18 in the horizontal direction via a slide rail, and the forming cavity pillars 1112 extend in the vertical direction. Preferably, the forming cavity pillars 1112 are right-angled structures composed of two rectangular rods. The seventh driving device 1113 drives the fourth slide 1111 to move the forming cavity pillars 1112, thereby adjusting the size of the cavity 112 to adapt to the preparation of polygonal boxes of different specifications and to avoid interference with the demolding unit 16. When applied to the preparation of an octagonal box, the two-cavity assembly 111 can be specifically used to complete the thorough bonding of the two vertical sides of the octagonal box.

[0077] Preferably, the seventh drive device 1113 is a cylinder, with its fixed end connected to the frame 18 and its output end connected to the fourth slide block 1111. Of course, the seventh drive device 1113 can also be a hydraulic cylinder, an electric push rod, or other known drive devices. This invention does not specifically limit the seventh drive device 1113.

[0078] Referring to Figure 7, in this embodiment, the mold unit 12 and the supporting unit 13 are slidably mounted on the frame 18 via the same set of slide rails to better control the consistency and clamping accuracy of the synchronous operation of the mold unit 12 and the supporting unit 13. Specifically, the mold unit 12 is located above the supporting unit 13. When the mold unit 12 is in its highest initial position, there is a gap between the mold unit 12 and the supporting unit 13 so that there is enough space to place the enclosure 6 between the mold unit 12 and the supporting unit 13. The first driving device 101 is mounted on the frame 18 and drives the mold unit 12 to rise and fall. The second driving device 102 is also mounted on the frame 18 and drives the supporting unit 13 to rise and fall.

[0079] As an example, both the first drive device 101 and the second drive device 102 can be driven by a motor and a belt to drive the mold unit 12 and the support unit 13 respectively, so as to accommodate the large stroke of the mold unit 12 and the support unit 13.

[0080] Of course, the first driving device 101 and the second driving device 102 may also adopt other driving methods, such as motor-driven lead screw and slider structure, motor-driven gear and rack structure, motor-driven sprocket and chain structure, long cylinder, long oil cylinder, etc. The present invention does not specifically limit the first driving device 101 and the second driving device 102.

[0081] Referring to Figures 8 to 10, in this embodiment, the mold unit 12 includes a first slide 121, a mold 122, and a negative pressure device 123 for adsorbing the base plate 5. The mold 122 is disposed on the first slide 121, which is slidably mounted on the frame 18. The first driving device 101 drives the first slide 121 to move the mold 122. The negative pressure device 123 is located in the mold 122 on the end face 1221 corresponding to the base plate 5. Thus, the base plate 5 is adsorbed onto the end face 1221 of the mold 122 by the negative pressure device 123, which is convenient and quick.

[0082] Preferably, the mold 122 is detachably mounted on the first slide 121. The mold 122 has an end face 1221 and a circumferential side face 1222 adapted to the prepared polygonal box. The end face 1221 is arranged vertically and is parallel to the moving direction of the mold unit 12.

[0083] Specifically, the first slide block 121 includes a connecting plate 1211, a hollow tube 1212, a first end cap 1213, a fixing sleeve 1214, a second end cap 1215, and an air pipe connector 1216. The first end of the hollow tube 1212 is provided with the first end cap 1213, and the second end of the hollow tube 1212 is provided with the second end cap 1215. The negative pressure device 123 is a negative pressure suction cup, which is located on the first end cap 1213 and connected to the hollow tube 1212. The second end cap 1215 is provided with the air pipe connector 1216, which is also connected to the hollow tube 1212. The air pipe connector 1216 can be connected to an external negative pressure pump or other devices via an air pipe. The connecting plate 1211 is slidably mounted on the frame 18 via a slide rail and is connected to the belt in the first drive device 101. The fixing sleeve 1214 is fixedly connected to the outside of the connecting plate 1211 by bolts. The second end of the hollow tube 1212 is inserted into the fixing sleeve 1214 and fixed by the fixing sleeve 1214. The air pipe connector 1216 protrudes towards the inside of the connecting plate 1211 for air pipe installation. The interior of the mold 122 is hollow. The end face 1221 of the mold 122 is provided with a first through hole 1223 and the back face of the mold 122 is provided with a second through hole 1224. The first through hole 1223 and the second through hole 1224 are both connected. The diameter of the first through hole 1223 is smaller than the diameter of the second through hole 1224. The hollow tube 1212 is inserted into the second through hole 1224, and a part of the first end cap 1213 is inserted into the first through hole 1223. The negative pressure suction cup is located at the first through hole 1223.

[0084] In this way, the negative pressure airflow acts on the negative pressure suction cup through the air pipe connector 1216 and the hollow tube 1212. The hollow tube 1212 is directly used as a channel to guide the negative pressure airflow. The overall structure is simple and facilitates the movement of the mold 122.

[0085] Specifically, the end face 1221 is recessed inward to form a shallow groove 12211 so that a protrusion 12212 is formed around the end face 1221. The negative pressure device 123 is located in the shallow groove 12211. Specifically, the negative pressure device 123 is located at the center of the shallow groove 12211. The width of the protrusion 12212 is preferably between 3 mm and 20 mm.

[0086] Thus, the shallow groove 12211 corresponds to the middle part of the base plate 5, and the protrusion 12212 corresponds to the edge of the base plate 5. When the negative pressure device 123 adsorbs the base plate 5, the shallow groove 12211 avoids the middle part of the base plate 5 from any support other than the negative pressure device 123, thereby preventing the edge of the base plate 5 from warping. This allows the edge of the base plate 5 to make full contact with the protrusion 12212 with precise positioning, ensuring the bonding effect between the base plate 5 and the surrounding plate 6.

[0087] Referring to Figure 11, in this embodiment, the supporting unit 13 includes a second slide 131 and two support plate assemblies 132 for clamping the enclosure 6. The two support plate assemblies 132 are spaced apart on the second slide 131, which is slidably mounted on the frame 18. The second driving device 102 drives the second slide 131 to move the two support plate assemblies 132. In this way, the two support plate assemblies 132 can better clamp the enclosure 6.

[0088] Preferably, in this embodiment, the pallet assembly 132 includes a first mounting base 1321, a first pallet 1322, a second pallet 1323, and a third driving device 1324. The first mounting base 1321 is disposed on the second slide 131, the first pallet 1322 is disposed on the first mounting base 1321, the second pallet 1323 is rotatably disposed on the first pallet 1322, and the third driving device 1324 drives the second pallet 1323 to rotate relative to the first pallet 1322 so that an angle is formed between the second pallet 1323 and the first pallet 1322 for the corner of the corresponding enclosure 6.

[0089] In another preferred embodiment, the second tray 1323 can also be rotatably disposed on the first mounting base 1321 so that the second tray 1323 can be flipped relative to the first tray 1322.

[0090] More preferably, the third driving device 1324 is a cylinder, with its fixed end rotatably mounted on the first mounting base 1321 and its output end rotatably mounted on the second support plate 1323. The cylinder can drive the second support plate 1323 to flip during extension and retraction. Of course, the third driving device 1324 can also be a hydraulic cylinder, an electric push rod, or other known driving devices; this invention does not specifically limit the third driving device 1324.

[0091] The first support plate 1322 and the second support plate 1323 are both elongated strips and have flat supporting surfaces. The first support plate 1322 can be supported under one side panel of the enclosure 6, and the second support plate 1323 can be supported under the other side panel of the enclosure 6. The first support plate 1322 and the second support plate 1323 can be unfolded in a plane or form an angle corresponding to the corner of the enclosure 6. Thus, before the mold unit 12 is pressed down, the surrounding plate 6 can be placed on the first tray 1322 and the second tray 1323, which are unfolded in a plane. After the mold unit 12 is pressed down, the first tray 1322 can clamp its corresponding side plate directly below the circumferential side 1222 of the mold 122. The third driving device 1324 drives the second tray 1323 to flip, and the second tray 1323 lifts its corresponding side plate upward and clamps it on the side of the circumferential side 1222 of the mold 122, thereby realizing the multi-purpose of the tray assembly 132. Taking the preparation of an octagonal box as an example, the two tray assemblies 132 can be specifically used to complete the bonding of the lower horizontal edge and the two lower oblique edges of the octagonal box.

[0092] Preferably, in this embodiment, the supporting unit 13 further includes a fourth driving device 133. Both pallet assemblies 132 are slidably mounted on the second slide block 131. The fourth driving device 133 drives the two pallet assemblies 132 to move closer or further apart to adjust the distance between the two pallet assemblies 132. Thus, by adjusting the distance between the two pallet assemblies 132, it is possible to adapt to the manufacture of polygonal boxes of different specifications. Specifically, the second slide block 131 is provided with a first guide rail 1311, and the first mounting seats 1321 of both pallet assemblies 132 are slidably mounted on the first guide rail 1311.

[0093] In another preferred embodiment, only one pallet assembly 132 may be slidably mounted on the second slide block 131. In this case, the fourth drive device 133 only drives the pallet assembly 132 to move, and can also adjust the distance between the two pallet assemblies 132. At this time, since one of the pallet assemblies 132 is stationary, it is necessary to adjust the position of the mold unit 12 and the cavity unit 11 accordingly. Alternatively, the stationary pallet assembly 132 may not have the function of clamping the two side plates.

[0094] Therefore, it is preferable that both pallet assemblies 132 are slidably mounted on the second slide block 131.

[0095] More preferably, the fourth driving device 133 includes a lead screw 1331 and a handle 1332, which are connected in a transmission manner. The lead screw 1331 is provided with a first threaded section and a second threaded section with opposite thread directions. The first threaded section and the second threaded section are respectively connected in a transmission manner to different pallet assemblies 132. The handle 1332 drives the lead screw 1331 to rotate, and the lead screw 1331 drives the two pallet assemblies 132 to move closer or further apart. Specifically, the first mounting base 1321 in the first pallet assembly 132 is provided with a first internal thread that mates with the first threaded section, and the first mounting base 1321 in the second pallet assembly 132 is provided with a second internal thread that mates with the second threaded section; the lead screw 1331 and the handle 1332 are both rotatably mounted on the first mounting base 1321, the end of the lead screw 1331 is provided with a first gear 1333, and the end of the handle 1332 is provided with a second gear 1334. The first gear 1333 and the second gear 1334 mesh to realize the manual adjustment of the gap between the two pallet assemblies 132.

[0096] Referring to Figures 5 and 12, in this embodiment, there are two pressing units 14, which are located on both sides of the input end of the cavity unit 11, so as to press the two ends of the surrounding plate 6 respectively, so that the back of the polygonal box is glued under the action of the pressing unit 14.

[0097] Specifically, the pressing unit 14 includes a third slide 141 and a pressing roller 142 for pressing the surrounding plate 6. The third slide 141 is slidably mounted on the frame 18, and the pressing roller 142 is rotatably mounted on the third slide 141. The fifth drive device 103 drives the third slide 141 to move the pressing roller 142. In this way, by using the rotatably mounted pressing roller 142 to press the surrounding plate 6, friction can be reduced, resulting in a better pressing effect. Taking the preparation of an octagonal box as an example, the two pressing rollers 142 can be specifically used to complete the bonding of the upper horizontal edge and the two upper inclined edges of the octagonal box.

[0098] Preferably, the fifth drive device 103 is a cylinder, with its fixed end connected to the frame 18 and its output end connected to the third slide 141. Of course, the fifth drive device 103 can also be a hydraulic cylinder, an electric push rod, or other known drive devices. This invention does not specifically limit the fifth drive device 103.

[0099] Referring to Figures 5 and 13, in this embodiment, the swing arm unit 15 includes a rotating base 151 and a swing plate 152. The rotating base 151 is rotatably mounted on the frame 18, and the swing plate 152 is mounted on the rotating base 151. The sixth driving device 104 drives the rotating base 151 to cause the swing plate 152 to swing. Specifically, the swing plate 152 is elongated and is specifically used to support the bottom edge of the surrounding plate 6. The rotating base 151 can also be used to support the surrounding plate 6 to prevent the surrounding plate 6 from tilting when it is laid flat. The rotation axis of the rotating base 151 is close to the input end of the cavity unit 11.

[0100] Thus, the swing arm unit 15 has two states: a flat state and an upward swing state. In the flat state, the swing plate 152 supports the lower part of the surrounding plate 6. In the upward swing state, the swing plate 152 clamps the surrounding plate 6 onto the mold unit 12. Taking the preparation of an octagonal box as an example, the two swing plates 152 can be specifically used to complete the initial bonding of the two vertical sides of the octagonal box.

[0101] Preferably, the sixth drive device 104 includes a swing arm motor 1041, an eccentric rod 1042, and a transmission rod 1043. The swing arm motor 1041 is mounted on the frame 18. One end of the eccentric rod 1042 is fixedly connected to the output shaft of the swing arm motor 1041, and the other end of the eccentric rod 1042 is rotatably connected to one end of the transmission rod 1043. The other end of the transmission rod 1043 is rotatably connected to the rotary seat 151, thereby realizing the drive of the rotary seat 151.

[0102] Of course, the sixth drive device 104 can also use other known drive devices such as a motor plus gear transmission to drive the rotary table 151. The present invention does not specifically limit the sixth drive device 104.

[0103] Preferably, the pressing unit 14 is located between the swing arm unit 15 and the cavity unit 11 to avoid interference between the pressing unit 14 and the swing arm unit 15.

[0104] Referring to Figures 5 and 14, in this embodiment, the demolding unit 16 includes two spaced demolding template components 161 and an eighth driving device 162. The two demolding template components 161 correspond to the two opposite sides of the prepared polygonal box, and the eighth driving device 162 synchronously drives the two demolding template components 161 to demold the prepared polygonal box from the cavity unit 11.

[0105] Specifically, the demolding template assembly 161 includes a second mounting base 1611, a demolding template 1612, and a demolding guide rail 1613. The second mounting base 1611 extends horizontally and is mounted on the frame 18 or on the ground. The demolding template 1612 slides horizontally on the second mounting base 1611 via the demolding guide rail 1613. The eighth drive device 162 includes a demolding motor 1621, a rotating rod 1622, and two demolding belts 1623. The demolding motor 1621 can be mounted on the frame 18 via a base or... The device is installed on the ground, with a rotating rod 1622 rotatably positioned between two second mounting bases 1611. The rotating rod 1622 is connected to the demolding template 1612 via a demolding belt 1623, and a demolding motor 1621 is connected to the rotating rod 1622. Thus, the demolding motor 1621 drives the rotating rod 1622 to rotate, and the rotating rod 1622 simultaneously drives the two demolding templates 1612 to slide via the two demolding belts 1623. The sliding of the demolding templates 1612 demolds the prepared polygonal box from the cavity unit 11.

[0106] Specifically, the demolding motor 1621 and the rotating rod 1622 can be connected by means of belt drive, gear drive, direct drive of coupling, etc.

[0107] Referring to Figures 5 and 15, in this embodiment, the flipping unit 17 includes a third mounting base 171, a flip plate 172, and a ninth driving device 173. The third mounting base 171 is vertically arranged and can be installed on the frame 18 or on the ground. The flip plate 172 is rotatably connected to the upper end of the third mounting base 171 and extends toward the cavity unit 11. Specifically, the rotation axis of the flip plate 172 is arranged horizontally. The ninth driving device 173 drives the flip plate 172 to flip the polygonal box by 90 degrees. In application, a conveyor belt can also be provided on one side of the flipping unit 17, so that the flipped polygonal box can fall into the conveyor belt and be sent away.

[0108] Preferably, the ninth drive device 173 is a cylinder, with its fixed end rotatably connected to the frame 18, the third mounting base 171, or a fixed base mounted on the ground, and its output end connected to the flap 172. Of course, the ninth drive device 173 can also be a hydraulic cylinder, an electric actuator, or other known drive devices; this invention does not specifically limit the ninth drive device 173.

[0109] This embodiment also discloses a method for preparing multi-cornered boxes using the aforementioned box-making machine, comprising the following steps:

[0110] Step A: The enclosure panel 6 is unloaded and conveyed to the bottom edge gluing module 3. Specifically, the enclosure panel unloading module 2 separates and outputs the enclosure panels 6 stored in the hopper one by one. During the output of a single enclosure panel 6, the oblique edge gluing device 7 applies glue to the oblique edge of one end of the enclosure panel 6. After the enclosure panel 6 stops, the back adhesive device 8 applies tape to the back of one end of the enclosure panel 6. Preferably, the oblique edge gluing and back adhesive tape application operations are performed on the same end of the enclosure panel 6.

[0111] Step B: In the bottom edge gluing module 3, glue is applied to the bottom edge of the enclosure 6, and it is then conveyed to the input end of the cavity unit 11 in the molding module 1. Specifically, Step B is performed after Step A. In Step B, the clamping and pulling device 31 is used to clamp the end of the enclosure 6 without backing glue and pull the enclosure 6 downwards towards the transfer device 33. While the clamping and pulling device 31 is pulling the enclosure 6, the bottom edge gluing device 32 applies glue to the bottom edge of the enclosure 6. The transfer device 33 is used to convey the enclosure 6, which has undergone bottom edge gluing, oblique edge gluing, and backing glue application, to the molding module 1. Preferably, the transfer device 33 uses multiple suction cups to convey the enclosure 6 horizontally to the bottom of the mold unit 12.

[0112] Step C: The base plate 5 is discharged and, after being erected, is conveyed to the mold unit 12 in the forming module 1. Specifically, the base plate discharge module 4 separates and outputs the base plates 5 stored in the hopper one by one, and erects the base plates 5. Then, the mold unit 12 adsorbs the erected base plates 5 onto its end face 121.

[0113] Step D: After the base plate 5 and the surrounding plate 6 are both conveyed to the forming module 1, the box is unloaded.

[0114] In the molding module 1, the mold unit 12 carries the base plate 5 downward and presses down on the surrounding plate 6 so that the lower edge of the base plate 5 is bonded to the surrounding plate 6.

[0115] Thus, the polygonal box is prepared through the above steps. When the polygonal box is formed at the forming module 1, the base plate is erected and the surrounding plate is laid flat. The polygonal box is prepared by loading the base plate first and then pressing the surrounding plate together, which makes the prepared polygonal box have a good bonding effect and a high yield.

[0116] In addition, this embodiment also discloses an octagonal box forming method using the above-mentioned forming module 1 to prepare an octagonal box. That is, a refined step scheme for preparing the octagonal box in step D above.

[0117] For ease of understanding, referring to the direction shown in Figure 18, the eight perimeters of the base plate 5 are defined as perimeter A, perimeter B, perimeter C, perimeter D, perimeter E, perimeter F, perimeter G, and perimeter H, respectively. The eight side plates of the enclosure plate 6 are defined as side plate a, side plate b, side plate c, side plate d, side plate e, side plate f, side plate g, and side plate h, respectively. When preparing the octagonal box, perimeter A and side plate a are bonded together to form the upper left diagonal edge of the octagonal box, perimeter B and side plate b are bonded together to form the left vertical side of the octagonal box, perimeter C and side plate c are bonded together to form the lower left diagonal edge of the octagonal box, perimeter D and side plate d are bonded together to form the lower horizontal edge of the octagonal box, perimeter E and side plate e are bonded together to form the lower right diagonal edge of the octagonal box, perimeter F and side plate f are bonded together to form the right vertical side of the octagonal box, perimeter G and side plate g are bonded together to form the upper right diagonal edge of the octagonal box, and perimeter H and side plate h are bonded together to form the upper horizontal edge of the octagonal box.

[0118] Referring to Figures 4, 5, and 16 to 18, the steps of this octagonal box forming method include:

[0119] Step S1: Loading the base plate 5 and the surrounding plate 6: Load the base plate 5 into the mold unit 12. Specifically, after the base plate 5 is erected, the negative pressure device 123 adsorbs the base plate 5 onto the end face 1221 of the mold 122. Load the surrounding plate 6 into the input end of the cavity unit 11 and position the surrounding plate 6 between the mold unit 12 and the support unit 13. Specifically, both the support unit 13 and the swing arm unit 15 can be supported below the surrounding plate 6.

[0120] Step S2: Complete the bonding of the lower horizontal edge in the octagonal box: The mold unit 12 presses down with the base plate 5, and the mold unit 12 pre-presses the surrounding plate 6 onto the supporting unit 13. Specifically, referring to Figures 4 and 18, the first driving device 101 is activated, and the mold 122 presses down to clamp the side plate b onto the first support plate 1322 in the two supporting units 13, so that the periphery D and the side plate b are bonded together.

[0121] Step S3: Complete the bonding of the two lower beveled edges in the octagonal box: After step S2 is completed, the second support plate 1323 in the supporting unit 13 flips to clamp the lower beveled edges in the octagonal box. Specifically, referring to Figures 16 and 18, the third drive device 1324 is activated, and the third drive device 1324 drives the second support plate 1323 to flip, lifting the side plate c and the side plate e to clamp them into the mold 122, so that the periphery C and the side plate c are bonded together, and the periphery E and the side plate e are bonded together.

[0122] Step S4: Complete the initial bonding of the two vertical sides in the octagonal box: The swing arm unit 15 bends both ends of the surrounding plate 6 upwards and clamps the surrounding plate 6 onto the mold unit 12. Specifically, referring to Figures 16 and 18, the sixth drive device 104 is activated, and the sixth drive device 104 drives the swing plate 152 to flip upwards. The two swing plates 152 bend both ends of the surrounding plate 6 respectively, lifting the side plate b and the side plate f to clamp them onto the mold 122, so that the periphery B and the side plate b are bonded together, and the periphery F and the side plate f are bonded together.

[0123] Preferably, steps S3 and S4 are performed simultaneously, but they can also be performed sequentially.

[0124] Step S5: Complete the bonding of the two vertical sides of the octagonal box: The mold unit 12 and the supporting unit 13, along with the bottom plate 5 and the surrounding plate 6, continue to press down to enter the cavity unit 11, where the bonding of the two vertical sides of the octagonal box is completed. Specifically, referring to Figures 17 and 18, the first driving device 101 and the second driving device 102 are activated synchronously, so that the mold unit 12 and the supporting unit 13 can press down simultaneously to enter the cavity 112 of the cavity unit 11. In the cavity unit 11, after being squeezed again by the cavity components 111 on both sides, the peripheral B and the side plate b are bonded more thoroughly, and the peripheral F and the side plate f are bonded more thoroughly. After that, the left and right swing plates 152 are reset.

[0125] Step S6: Complete the bonding of the two upper inclined edges and the upper horizontal edge in the octagonal box: The pressing unit 14 moves toward the mold unit 12, and the pressing unit 14 pre-presses the two ends of the surrounding plate 6 onto the mold unit 12, thus completing the preparation of the octagonal box. In step S6, preferably, one pressing unit 14 first moves toward the mold unit 12 to complete the bonding of one upper inclined edge and the upper horizontal edge in the octagonal box, and then the other pressing unit 14 moves toward the mold unit 12 to press the other upper inclined edge in the octagonal box, and the adhesive tape on the back of the subsequently pressed upper inclined edge is attached to the upper horizontal edge.

[0126] Specifically, referring to Figures 17 and 18, firstly, the right-side pressing unit 14 operates. After the right-side fifth driving device 103 is activated, it drives the right-side pressing roller 142 to move horizontally to the left. The right-side pressing roller 142 pushes against side plate g and side plate h, clamping them sequentially into the mold 122, so that periphery G and side plate g are bonded together, and periphery H and side plate h are bonded together. Then, the left-side pressing unit 14 operates first. After the left-side fifth driving device 103 is activated, it drives the left-side pressing roller 142 to move horizontally to the right. The left-side pressing roller 142 pushes against side plate a, clamping it into the mold 122, so that periphery A and side plate a are bonded together. The left-side pressing roller 142 continues to move horizontally to the right, so that the adhesive tape on the back of side plate a is bonded to side plate h. In this way, the bonding of the two upper oblique edges and the upper horizontal edge in the octagonal box is completed, and the overall preparation of the octagonal box is completed.

[0127] Step S7: Demolding the prepared octagonal box: Referring to Figure 5, after step S6 is completed, the mold unit 12 and the supporting unit 13 continue to press down until the box-flipping unit 17 supports the bottom of the octagonal box. The supporting unit 13 continues to detach from the octagonal box, and the two cavity assemblies 111 move outward to detach from the octagonal box. Then the demolding unit 16 is activated, and the eighth driving device 162 drives the two demolding templates 1612 to move outward to demold the octagonal box from the mold 122.

[0128] Step S8: Flip the demolded octagonal box: After step S7 is completed, the ninth drive device 173 is started. The ninth drive device 173 drives the flip plate 172 to flip, and the flip plate 172 rotates the octagonal box 90 degrees so that the bottom plate 5 in the octagonal box faces down.

[0129] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
