Figure 4 The figure shows the structural diagram of the material receiving mechanism in the embodiment of the present application. Figure 5 Shown is a structural schematic diagram of the folding mechanism in an embodiment of the present application.

[0054] Please refer to Figures 2 to 5 The automatic box folding device includes a material receiving mechanism 100 and a folding mechanism 200.

[0055] Among them, the material receiving mechanism 100 includes a material receiving drive 110 and a first material suction component 120. The material receiving drive 110 is used to drive the first material suction component 120 to reciprocate between the first workstation and the second workstation along the material receiving direction JL. The first material suction component 120 is used to adsorb the position corresponding to the bottom side panel 014 on the first surface of the carton plate 01.

[0056] The flanging mechanism 200 includes a first flanging assembly 210 , a second flanging assembly 220 and a third flanging assembly 230 .

[0057] The first flanging assembly 210 includes a guide push plate 211 and two lifting members 212 located at the second station. The guide push plate 211 extends along the material connection direction JL, and the two lifting members 212 are respectively arranged on both sides of the guide push plate 211 along the first direction D1. The guide push plate 211 is located on the first side of the first suction assembly 120 in the second direction D2. The first direction D1 and the second direction D2 are perpendicular to each other and are parallel to the board surface of the carton board 01 at the second station; when the first suction assembly 120 moves from the first station to the second station, the guide push plate 211 passively pushes the rear side plate 011 of the carton board 01 to fold toward one side of the second surface of the carton board 01, and the two lifting members 212 synchronously and passively push the free ends of the left bottom adhesive wing 015 and the right bottom adhesive wing 016 of the carton board 01 to fold and tilt toward one side of the second surface of the carton board 01.

[0058] The second flanging assembly 220 includes two flanging driving members 221. After the rear side panel 011 is folded, the two flanging driving members 221 are used to respectively drive the left side panel 012 and the right side panel 013 of the carton panel 01 to fold along the second side of the second direction D2, and the left bottom adhesive flap 015 and the right bottom adhesive flap 016 of the carton panel 01 are simultaneously flipped toward the second side of the second direction D2.

[0059] The third flanging assembly 230 includes two flap driving components 231 and a front-flipping driving component 232. After the left side panel 012 and the right side panel 013 are folded, the two flap driving components 231 respectively drive the left sticky wing 018 and the right sticky wing 019 of the carton plate 01 to fold toward the side of the second surface of the carton plate 01; after the left sticky wing 018 and the right sticky wing 019 are folded, the front-flipping driving component 232 is used to drive the front side panel 017 of the carton plate 01 to fold toward the side of the second surface of the carton plate 01, and the left sticky wing 018 and the right sticky wing 019 are synchronously flipped toward the first side of the second direction D2.

[0060] It should be noted that the first surface of the carton board 01 is the outer surface of the pre-folding box 02 , which is usually a printed surface, and the second surface of the carton board 01 is the inner surface of the pre-folding box 02 .

[0061] It should be understood that the first material suction component 120 absorbs the first surface of the bottom side plate 014 of the carton plate 01, and when the material receiving drive 110 drives the first material suction component 120 to move along the material receiving direction JL, it will drive the carton plate 01 to move; the guide push plate 211 of the first flanging component 210 is relatively stationary, because the guide push plate 211 and the two lifting plate members 212 are both located at the second station, the guide push plate 211 is located on the first side of the first material suction component 120 in the second direction D2, and the two lifting plate members 212 are respectively provided on both sides of the guide push plate 211 along the first direction D1. Therefore, when the material receiving drive 110 drives the first material suction component 120 to move from the first station to the second station, the first material suction component 120 will drive the carton plate 01 to move synchronously from the first station to the second station, and the guide push plate 211 can push the rear side plate 011 of the carton plate 01 (the rear side plate 011 is located at the bottom side plate 01 When the left and right panels 012 and 013 are folded, the left and right panels 012 and 013 are pushed to fold over, thereby completing the first flanging operation. When the panel 01 reaches the second station, the two lifting members 212 passively push the left and right bottom adhesive flaps 015 and 016 of the panel 01 to flip over toward the second side of the panel 01, so that the free ends of the left and right bottom adhesive flaps 015 and 016 are not coplanar with the bottom side panel 014, and the free ends of the left and right bottom adhesive flaps 015 and 016 are at the side of the bottom side panel 014 away from the first suction assembly 120. In this way, when the left and right panels 012 and 013 are folded over in the next step, the left and right bottom adhesive flaps 015 and 016 may not interfere with the bottom side panel 014, thereby ensuring the normal progress of the next flanging operation.

[0062] After the rear side panel 011 is folded, the two flipping driving members 221 of the second flipping assembly 220 respectively drive the left side panel 012 and the right side panel 013 of the carton panel 01 to flip along the second side of the second direction D2, and the left bottom adhesive wing 015 and the right bottom adhesive wing 016 of the carton panel 01 will be synchronously flipped along the second side of the second direction D2 to complete the second flipping operation.

[0063] After the left side panel 012 and the right side panel 013 are folded, the two flap driving parts 231 of the third flanging assembly 230 respectively drive the left sticky flap 018 and the right sticky flap 019 of the carton plate 01 to fold toward the second side of the carton plate 01, so that the free ends of the left sticky flap 018 and the right sticky flap 019 are inclined toward the side close to each other, and how to fold the left sticky flap 018 and the right sticky flap 01 to the inner side of the left side panel 012 and the right side panel 013, so that when the front side panel 017 is folded in the next step, the left sticky flap 018 and the right sticky flap 01 will not interfere with the left side panel 012 and the right side panel 013, thereby ensuring the normal progress of the next flanging operation. After the left adhesive wing 018 and the right adhesive wing 01 are folded, the front driving member 232 drives the front side plate 017 of the carton plate 01 to fold toward one side of the second side of the carton plate 01, and the left adhesive wing 018 and the right adhesive wing 019 will be synchronously flipped toward the first side of the second direction D2 to complete the third flanging operation.

[0064] In the automatic box folding device provided by this embodiment, the reciprocating movement of the material receiving mechanism 100 and the automated flipping action of the folding mechanism 200 are coordinated to achieve the folding of the carton board 01 into the pre-folded box 02, replacing manual folding, reducing labor intensity, and improving folding efficiency. In addition, the first flanging assembly 210, the second flanging assembly 220, and the third flanging assembly 230 of the folding mechanism 200 complete the folding of the rear side panel 011, the left side panel 012, the right side panel 013, the front side panel 017, the left bottom adhesive flap 015, the right bottom adhesive flap 016, the left adhesive flap 018, and the right adhesive flap 019 according to a preset trajectory and timing. The mechanical structure ensures the accuracy of the action, avoiding the problems of skewed folding edges and misaligned adhesive flaps caused by differences in experience during manual folding, and ensuring uniform and stable folding quality. Each flanging component has a clear division of labor: the first flanging component 210 realizes passive folding of the rear side panel 011 through the guide plate 211; the second flanging component 220 completes the folding of the left side panel 012, the right side panel 013, the left bottom adhesive wing 015, and the right bottom adhesive wing 016 of the carton panel 01 through two flanging driving components 221; the third flanging component 230 completes the folding of the left adhesive wing 018 and the right adhesive wing 019 through two flanging driving components, and completes the folding of the front side panel 017 through the front flanging driving component 232; the structure of each flanging component is reasonably distributed, the overall structure of the device is simple, the material receiving mechanism 100 and the folding mechanism 20 are modularly arranged and act independently, which can reduce component interference, can be targeted for maintenance, and is highly convenient to maintain.

[0065] Figure 6 The figure shows a schematic diagram of the three-dimensional structure of the automatic box folding device provided in an embodiment of the present application. Figure 7 Shown Figure 6 A partial enlarged view of Figure 8 Shown is a schematic top view of the structure of the automatic box folding device provided in an embodiment of the present application.

[0066] See also Figure 3 、 Figures 6 to 8 In some embodiments, the automatic box folding device further includes a loading mechanism 300 and a feeding mechanism 400; the loading mechanism 300 includes a paper tray 310 and a loading drive 320, the paper tray 310 is used to place multiple carton boards 01, and the loading drive 320 is used to drive the paper tray 310 to reciprocate along the loading direction; the feeding mechanism 400 includes a feeding drive 410 and a second suction component 420, the feeding drive 410 is used to drive the second suction component 420 to reciprocate between the paper tray 310 and the first suction component 120, and the second suction component 420 is used to adsorb the second side of the carton board 01.

[0067] In a specific embodiment (combined Figure 3 、 Figure 6 and Figure 8 The automatic box folding device shown in the figure) is provided with corresponding sensors at multiple key workstations and material picking positions to achieve automated and precise control. In the automatic box folding device, the loading direction is the up and down direction, and multiple paper box plates 01 stacked in the vertical direction are placed on the paper tray 310, and the loading mechanism 300 is located on one side of the receiving mechanism 200 along the second direction D2. The loading process is as follows: the loading drive 320 drives the paper loading tray 310 and the multiple paper box plates 01 placed thereon to rise. When the top paper box plate 01 reaches the material picking position, the loading sensor provided at the material picking position will send a loading signal to the feeding mechanism 400. After the feeding drive 410 receives the signal, the feeding drive 410 drives the second suction component 420 to move to the material picking position. After the second suction component 420 adsorbs the second side of the top paper box plate 01, the feeding drive 410 drives the second suction component 420 to move to the first station; at this time, the material receiving sensor provided at the first station sends a material receiving signal to the material receiving mechanism 100. After the material receiving mechanism 100 receives the material receiving signal, the material receiving drive 110 drives the first suction component 120 to move from the first station to the second station, and the folding mechanism 200 performs flanging and folding on the paper box plate 01 (the specific folding process is as described above and will not be repeated here). It should be noted that when the number of carton sheets 01 on the paper tray 310 is insufficient, the loading drive 320 can drive the paper tray 310 to descend, allowing the operator to replenish the carton sheets 01 on the paper tray 310, thereby ensuring a continuous supply of materials. The configuration of these sensors provides precise signal transmission for the coordinated operation of various mechanisms, ensuring the automated and efficient operation of the entire box folding process.

[0068] In this embodiment, the loading mechanism 300 achieves centralized storage of multiple carton boards 01 through the paper tray 310, which can load a large number of carton boards 01 in batches at one time, effectively increasing the logistics reserve for a single loading. The second suction component 420 of the feeding mechanism 400 establishes a stable automated transmission path between the paper tray 310 and the first suction component 120 of the receiving mechanism 100. Through precise adsorption action and displacement control, the carton boards 01 in the paper tray 310 are transferred to the receiving mechanism 200 in an orderly manner. This collaborative working mode enables the receiving mechanism 200 to continuously and stably obtain the carton boards 01 to be processed, completely getting rid of the production interruption problem caused by the traditional frequent manual loading. It ensures the automated and continuous operation of the entire folding process from the material supply link, significantly improving the overall operating efficiency of the equipment.

[0069] See also Figure 3 、 Figure 6 and Figure 8 In some embodiments, the automatic box folding device also includes a frame 500, the frame 500 is provided with a supporting plate 510, and the loading drive member 320 is installed on the supporting plate 510; the loading drive member 320 includes a loading motor 321, a loading nut 322 and a loading screw 323, the output shaft of the loading motor 321 is connected to the loading screw 323, and is used to drive the loading screw 323 to rotate; the loading nut 322 is installed on the supporting plate 510, the loading nut 322 is screwed to the loading screw 323, and the loading screw 323 is rotatably connected to the paper loading tray 310.

[0070] by Figure 3 As an example, the specific embodiment shown in FIG. Figure 6 and Figure 8 In this automatic box folding device, when the feeding mechanism 300 is operating, the feeding motor 321 is activated, and the output shaft of the feeding motor 321 drives the feeding screw 323 to rotate synchronously. Because the feeding screw 322 is mounted on the carrier plate 510, the feeding screw 323 is threadedly connected to the feeding nut 322, and the feeding nut 322 is mounted on the carrier plate 510, the feeding nut 322 is stationary relative to the carrier plate 510. The rotating feeding screw 323 will produce an upward or downward movement along the axial direction, thereby driving the connected paper tray 310 to move synchronously along the feeding direction (up and down direction). It should be noted that the movement direction of the paper tray 310 is determined by the direction of rotation of the feeding motor 321: if the feeding motor 321 drives the paper tray 310 to rise when rotating forward, the paper tray 310 will correspondingly descend when rotating reversely; conversely, if the paper tray 310 descends when rotating forward, the paper tray 310 will rise when rotating reversely. This transmission structure achieves precise bidirectional control of the paper tray through the forward and reverse rotation of the motor, ensuring a stable and reliable loading process.

[0071] In this embodiment, the supporting plate 510 of the frame 500 provides a stable installation foundation for the feeding mechanism 300, and the feeding drive 320 adopts a "motor-screw-nut" transmission structure. The feeding motor 321 drives the feeding screw 323 to rotate, and the feeding screw 323 and the feeding nut 322 are screwed together to convert the rotational motion into a smooth linear motion of the paper tray 310. This transmission method has high precision and controllable stroke, and can accurately adjust the feeding position of the paper tray 310. In addition, the transmission parameters of the feeding screw 323 (such as speed and stroke) can be flexibly adjusted by the feeding motor 321, which is convenient for optimizing the feeding rhythm according to the actual folding box requirements. The precise feeding action can accurately match the adsorption rhythm of the feeding mechanism 400, avoid the failure of the second suction component 420 to pick up the material due to the position deviation of the paper tray 310, ensure the seamless connection of the feeding-feeding link, and further improve the automation coordination efficiency of the overall device.

[0072] See also Figure 6 and Figure 8 In some embodiments, the feeding mechanism 300 further includes four limiting units, which are respectively arranged around the four sides of the paper loading tray 310. Each limiting unit includes at least one limiting baffle 330. The limiting baffle 330 is installed on the supporting plate 510, and the limiting baffle 330 abuts against the outer edge of the paper box plate 01.

[0073] In specific implementation, each limiting unit includes at least one limiting baffle 330. By adjusting the installation position of the limiting baffle 330 (such as moving along the preset adjustment hole of the supporting plate 510), it can adapt to the limiting requirements of carton boards 01 of different sizes.

[0074] In this embodiment, four limiting units are arranged around the paper loading tray 310, and the limiting baffle 330 can limit the displacement and rotation of the paper box plate 01 on the paper loading tray 310 by abutting against the outer edge of the paper box plate 01. In this way, even if the paper loading tray 310 shakes slightly during the reciprocating motion, or is slightly misaligned during stacking, the limiting baffle 330 can constrain the paper box plate 01 to the preset material picking area through physical limitation, thereby preventing the paper box plate 01 from sliding or deviating from the edge of the paper loading tray 310, ensuring that the second suction component 420 of the feeding mechanism 400 can accurately absorb the target paper box plate 01, and reducing the probability of material picking failure. In addition, the four limiting units can circumferentially regularize the multi-layer carton boards 01 stacked on the paper tray 310, ensuring that the edges of each layer of carton boards 01 are aligned, avoiding posture deviation of a single carton board 01 during adsorption due to skewed stacking, and reducing the crease misalignment problem caused by the poor initial posture of the carton board 01 during subsequent folding of the folding mechanism 200, thereby indirectly improving the folding quality of the pre-folded box 02.

[0075] See also Figure 6In some embodiments, the feeding drive 320 further includes a telescopic rod 340 , one end of the telescopic rod 340 is connected to the carrier plate 510 , and the other end of the telescopic rod 340 is connected to the paper tray 310 .

[0076] In this embodiment, the ends of the telescopic rod 340 are respectively connected to the carrier plate 510 and the paper tray 310, providing auxiliary support for the paper tray 310 as it reciprocates with the feeding screw 323. Furthermore, as the feeding screw 323 drives the reciprocating motion of the paper tray 310, the telescopic rod 340, through its linear telescopic properties, assists in correcting the motion trajectory, acting as a guide. This prevents the paper tray 310 from deflecting due to installation errors or component wear, ensures that the paper tray 310 always stays in the same material removal position, and ensures that it precisely interfaces with the second suction assembly 420 of the feeding mechanism 400, thereby improving the suction success rate.

[0077] See also Figures 7 to 9 In some embodiments, the automatic box folding device also includes a blanking mechanism 600, which includes a blanking cylinder 610. The blanking cylinder 610 is located on the first side of the guide plate 211 in the second direction D2. The blanking cylinder 610 is used to drive the pre-folding box 02 to move toward the second side of the second direction D2.

[0078] In this embodiment, the unloading cylinder 610 serves as a power source. After the folding mechanism 200 completes the folding of the pre-folding box 02, it can actively drive the pre-folding box 02 to move along the second side of the second direction D2, and move it out of the working area of ​​the folding mechanism 200 (such as the second workstation). This process does not require human intervention, so that the automatic folding device forms a complete automated process of "loading-folding-unloading", which can make room for the subsequent folding of the paper box board 01, avoid process stagnation caused by workstation occupation, and achieve precise matching of the folding rhythm of the unloading mechanism 600 and the folding mechanism 200, reduce the process interval time, and improve the overall folding efficiency of the device.

[0079] Furthermore, in this embodiment, the positioning of the unloading cylinder 610 (on the first side of the second direction D2 of the guide plate 211) forms a reasonable spatial coordination with the operating area of ​​the folding mechanism 200. Its driving direction is adapted to the placement of the pre-folding box 02 at the second station, enabling unloading to be completed without interfering with the subsequent operation of the folding mechanism 200. This coordinated layout reduces motion interference between mechanisms, reduces the risk of failure due to component collisions, and improves the overall operational stability of the equipment.

[0080] Figure 9 The figure shows the positional relationship structure diagram of the folding mechanism, the blanking mechanism and the receiving mechanism in the embodiment of the present application. Figure 10 The figure shows a schematic diagram of the connection structure between the tongue-folding cylinder and the tongue-folding part of the fourth flanging assembly in an embodiment of the present application.

[0081] See also Figure 2 、 Figures 7 to 10 In some embodiments, the carton board 01 further includes a cover plate 020 and two cover tongues 021. The cover plate 020 is connected to the side of the rear side plate 011 away from the bottom side plate 014, and the cover plate 020 is used to cover the seal of the pre-folding box 02; one cover tongue 021 is respectively connected to the side of the left side plate 012 away from the left bottom adhesive wing 015, and the other cover tongue 021 is connected to the side of the right side plate 013 away from the right bottom adhesive wing 016; the folding mechanism 200 further includes a fourth flanging component 240, and the fourth flanging component 240 is used to drive the two cover tongues 021 of the carton board 01 to fold along the first direction D1 toward the side close to each other.

[0082] In this embodiment, for the newly added cover plate 020 and two cover tongues 021 structure of the carton board 01, the fourth flange component 240 drives the cover tongue 021 to fold along the first direction D1 toward the side close to each other, so that the device can not only complete the folding of basic structures such as the front side panel 017, the rear side panel 011, the left side panel 012, and the right side panel 013, but also simultaneously realize the pre-folding of the cover tongue 021, providing a pre-forming basis for the subsequent sealing of the cover plate 020 and the final box formation, avoiding the additional process of manually folding the cover tongue 021 separately, and further improving the automation coverage.

[0083] See also Figures 7 to 10 In some embodiments, the fourth flanging assembly 240 includes two folding tongue cylinders 241 and a folding tongue member 242. The fixed end of each folding tongue cylinder 241 is connected to the frame 500, and the movable end of each folding tongue cylinder 241 is correspondingly connected to a folding tongue member 242. The folding tongue member 242 is used to drive the free end of the cover tongue 021 to fold toward the bottom side panel 014 of the pre-folding box 02 located at the second workstation.

[0084] For specific implementation, see Figure 10 The tongue folding member 242 includes a telescopic cylinder 2421, a support rod 2422 and a swing rod 2423. The fixed end of the telescopic cylinder 2421 is arranged at the movable end of the folding tongue cylinder 241. The movable end of the telescopic cylinder 2421 is hinged to the swing rod 2423. The middle part of the swing rod 2423 is hinged to one end of the support rod 2422. The other end of the support rod 2422 is connected to the fixed end of the telescopic cylinder 2421. That is, the folding tongue member 242 is a connecting rod structure. When the folding tongue member 242 is working, the movable end of the telescopic cylinder 2421 moves telescopically. When the movable end of the telescopic cylinder 2421 moves, it can drive the other end of the swing rod 2423 to swing. When the folding tongue member 242 drives the free end of the cover tongue 021, the swing direction of the swing rod 2423 is v (see Figure 10 ), the swing angle can be from 90° to 60°.

[0085] In this embodiment, the folding tongue member 242 acts directly on the cover tongue 021, and cooperates with the movement and extension of the folding tongue cylinder 241 to drive the two cover tongues 021 of the carton plate 01 to fold along the first direction D1 toward the side close to each other. At this time, the cover tongue 021 flips 90°; thereafter, the tongue folding member 242 folds along the preset trajectory of "towards the bottom side plate 014", and the cover tongue 021 continues to flip a certain angle (such as 90°), that is, the flipping angle of the cover tongue 21 increases (a total of 180° flipped), thereby ensuring the folding effect of the cover tongue 21.

[0086] See also Figure 4 and Figure 5 In some embodiments, the lifting plate 212 includes an inclined panel 2121, a fixed plate 2122 and a spring member (not shown in the figure), the inclined panel 2121 forms an acute angle with the bottom side plate 014 of the carton board 01 in the second station, and along the second direction D2 from the first side to the second side, the inclined panel is tilted along the second station toward the first station; the fixed plate 2122 is located on the side of the inclined panel 2121 close to the first adsorption component 120, the spring member is arranged between the fixed plate 2122 and the inclined panel 2121, and the two ends of the spring member are respectively connected to the fixed plate 2122 and the inclined panel 2121.

[0087] In this embodiment, the inclined panel 2121 forms an acute angle with the bottom side panel 014 of the carton board 01 and is inclined along a preset direction (along the second direction D2 from the first side to the second side, the inclined panel is inclined along the second station toward the first station). When the first suction component 120 drives the carton board 01 to move from the first station to the second station, the left bottom adhesive wing 015 and the right bottom adhesive wing 016 will naturally contact the inclined panel 2121 and be lifted up a certain angle along the inclined panel 2121, so that the free ends of the left bottom adhesive wing 015 and the right bottom adhesive wing 016 are tilted up and are not in the same plane with the bottom side panel 014. In this way, when the subsequent second flanging component 220 drives the left side panel 012 and the right side panel 013 to fold, the left bottom adhesive wing 015 and the right bottom adhesive wing 016 are prevented from interfering with the bottom side panel 014, ensuring that the left side panel 012 and the right side panel 013 can be folded smoothly. Among them, the left bottom adhesive wing 015 and the right bottom adhesive wing 016 are lifted up by the inclined panel 2121. When the second flanging assembly 220 drives the left side panel 012 and the right side panel 013 to fold, the crease of the left side panel 012 close to the left bottom adhesive wing 015 and the crease of the right side panel 013 close to the right bottom adhesive wing 016 will pass through the inclined panel 2121, and this crease will produce a certain pressure on the inclined panel 2121. The spring part is acted upon by the inclined panel 2121 and compressed and deformed. At the same time, the inclined panel 2121 moves toward the direction close to the fixed plate 2122 under the action of this pressure, so that the inclined panel 2121 avoids space and does not interfere with the left side panel 012 and the right side panel 013, thereby avoiding accidental deformation of the left side panel 012 and the right side panel 013 due to the action of the inclined panel 2121 during the folding, improving the folding quality, and providing a good foundation for subsequent manual adhesion.

[0088] Figure 11 The figure shows a schematic structural diagram of the positional relationship between the feeding drive member and the receiving drive member in an embodiment of the present application.

[0089] Combine Figure 6 、 Figure 7 and Figure 11In some embodiments, the feeding mechanism 300 is located on the side of the guide plate 211 away from the material receiving mechanism 200, and the material receiving direction and the feeding direction are both configured to be vertical; the feeding drive 410 includes a first transfer cylinder 411 and a second transfer cylinder 412, the fixed end of the first transfer cylinder 411 is connected to the frame 500, and the movable end of the first transfer cylinder 411 is connected to the fixed end of the second transfer cylinder 412, for driving the second transfer cylinder 412 to move along the second direction D2; the second suction assembly 420 includes at least one second suction cup, the second suction cup is used to adsorb the second side of the carton board 01, and the movable end of the second transfer cylinder 412 is connected to the second suction cup, for driving the second suction cup to move along the feeding direction; the material receiving drive 110 includes a material receiving cylinder, the fixed end of the material receiving cylinder is connected to the frame 500; the first suction assembly 120 includes at least one first suction cup, the first suction cup is used to adsorb the first side of the carton board 01, and the first suction cup is installed at the movable end of the material receiving cylinder.

[0090] In specific implementation, the first suction component 120 and the second suction component 420 can have multiple suction cups, and the multiple suction cups can be evenly distributed in a matrix. In this way, the adsorption force can be balanced, further reducing the risk of the carton board 01 falling off during the transfer process.

[0091] by Figure 3 As an example, the specific embodiment shown in FIG. Figure 6 、 Figure 7 and Figure 11 In this automatic box folding device, the feeding mechanism 400 operates as follows: the first transfer cylinder 411 drives the second transfer cylinder 412 to move in the second direction D2. The second transfer cylinder 412 drives the second suction assembly 420 connected thereto to move synchronously in the second direction D2. When the topmost carton board 01 reaches the pick-up position, the first transfer cylinder 411 drives the second transfer cylinder 412 to move along the first side of the second direction D2. The second transfer cylinder 412 drives the second suction cup to move vertically (descend) until it contacts the second surface of the carton board 01. The second suction cup generates negative pressure to absorb and fix the carton board 01. The second transfer cylinder 412 drives the second suction cup to move vertically (ascend) again, separating the carton board 01 from the underlying carton board 01. The first transfer cylinder 411 drives the second transfer cylinder 412 to move along the second side of the second direction D2 to a position above the first workstation. The second transfer cylinder 412 drives the second suction cup to transfer the carton board 01 to the first workstation.

[0092] In this embodiment, a double-layer drive structure is used in which the first transfer cylinder 411 drives the second transfer cylinder 412 to move along the second direction D2, and the second transfer cylinder 412 drives the second suction cup to move along the feeding direction. This achieves precise transfer of the carton board 01 in space, ensuring that the transmission path from the paper tray 310 to the material receiving mechanism 200 is efficient and stable. The first suction cup adsorbs the first side of the carton board 01, and the second suction cup adsorbs the second side of the carton board 01. The suction cup contacts the carton board 01 through negative pressure adsorption, and can closely fit the surface of the corrugated cardboard box board 01 (even if the surface is slightly uneven). This ensures that the carton board 01 is not easy to fall off or deflect during the transfer and processing process, thereby ensuring the accuracy of the subsequent folding process. Both the feeding mechanism 400 and the material receiving mechanism 100 adopt a combination of suction cup adsorption and cylinder drive. The suction cup is directly mounted on the movable end of the cylinder, and the overall structure is compact.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
