The forming conveyor 6 comprises a forming frame 61 and a vertical conveyor 62. The forming frame 61 comprises a bottom plate 611 and a forming plate 612, wherein a positioning sucker 613 is arranged on the bottom plate 611, and the forming plate 612 is fixedly connected to the edge of the bottom plate 611 along the normal direction. The vertical transporter 62 is a rack and pinion mechanism in the prior art, and is similar to the pushing mechanism 12 in structure, and this embodiment will not be described in detail. When the paperboard is positioned at the second station, the forming frame 61 is also transported to the second station, and the positioning suction cup 613 on the bottom plate 611 adsorbs the bottom panel, so that the forming frame 61 supports the box body from the inside, and the forming is ensured to be successful.

In addition, the frame is fixedly connected with the outer stop rods 58 arranged along the X axis on two sides of the second station, and two ends of each outer stop rod 58 extend outwards to form a guide part, so that the front panel and the rear panel folded at the first station cannot fall back in the process of pushing the paperboard from the first station to the second station.

As shown in connection with fig. 12, the vertical forming device 7 is located directly below the second station, and includes a width adjustment mechanism 71, a length adjustment mechanism 72, and a die plate 73.

The width adjustment mechanism 71 is mounted on the frame and includes a first adjustment platform 711 and a width adjustment drive 712. The frame is provided with a guide rail arranged along the Y axis at each of the two ends of the first adjustment platforms 711, so that the two ends of the two first adjustment platforms 711 are slidably connected with the guide rail, respectively, and the two first adjustment platforms 711 are arranged along the X axis and translate along the Y axis. The width adjustment driver 712 adopts a conventional rack and pinion mechanism, and this embodiment will not be described in detail.

Each first adjustment platform 711 has two length adjustment mechanisms 72 mounted thereto, each length adjustment mechanism 72 including a second adjustment platform 721 and a length adjustment drive 722. Both second adjustment platforms 721 are slidably connected to the first adjustment platform 711 by guide rails disposed along X. Each second adjustment stage 721 is driven by a respective length adjustment drive 722 and is slid along the X-axis. The length adjustment driving mechanism adopts the existing gear rack mechanism, and this embodiment is not described in detail.

The four adjusting platforms are fixedly connected with a vertically arranged template 73 respectively, each template 73 comprises a long-side guide plate 731 and a wide-side guide plate 732, the long-side guide plates 731 are arranged along the X axis, and the wide-side guide plates 732 are arranged along the Y axis, so that the long-side guide plates 731 and the wide-side guide plates 732 jointly form a forming cavity; the mold plate 73 for molding one side of the swing cover has a gap between the long side guide 731 and the wide side guide 732 so that the swing cover passes through the molding cavity. Further, the inner tips of the long side guide 731 and the wide side guide 732 are each formed with a chamfer.

In this way, the forming frame 61 is then raised, the cartons are left in the forming cavity and clamped by the clamping device 8 and continue to descend.

In order to prevent the carton from being carried out during the lifting process of the forming frame 61, as shown in fig. 13, a clamping plate 74 is provided at the upper portion of the mold plate 73, an opening is provided at the upper end of the wide edge guide 732, the clamping plate 74 is rotatably connected with the mold plate 73 through a horizontal shaft parallel to the wide edge guide 732, and the clamping plate 74 is formed with a counterweight end 741 and a carton end 742 at both ends, wherein the carton end 742 penetrates through the opening and extends into the forming cavity, and the counterweight end 741 has a mass greater than the carton end 742. When the clamping plate 74 is not influenced by external force, the clamping box is abutted against the upper end of the opening and stretches into the forming cavity under the influence of the counterweight end 741; when the carton is slid down, the carton abuts the carton end 742, causing the carton end 742 to flip down and out of the forming cavity from the opening.

In order to ensure the dead time of the carton in the forming cavity, an interceptor 75 is arranged at the lower part of the template 73, and is used as an interception piston cylinder of the interceptor 75, the cylinder body of the interceptor is fixedly connected on the outer side of the template 73, and the telescopic rod of the interceptor piston cylinder penetrates through the template 73. When the telescopic rod is extended, the telescopic rod penetrates through the template 73 and is positioned in the forming cavity; when the telescopic rod contracts, the telescopic rod is positioned at the outer side of the forming cavity, so that interception of the carton is realized through telescopic of the telescopic rod.

As shown in fig. 14, the box clamping device 8 stands on the lower side of the vertical forming device 7. The box clamping device 8 includes a lifting table 81, a box clamping mechanism 82, and a box clamping lifting driver 83.

The clamping box lifting driver 83 adopts the existing synchronous belt mechanism, and the lifting table 81 is connected with the frame in a sliding manner through a vertically arranged guide rail and fixedly connected to the synchronous belt, so that the lifting table 81 is driven to lift. The box clamping mechanism 82 is mounted on the lifting table 81 through a pitch changing mechanism 84.

The pitch mechanism 84 includes a carriage 841 and a pitch drive 842. Both the two carriages 841 are slidably connected to the lifting table 81 via a guide rail provided on the X-axis, and have two screw portions with opposite screw directions as a bidirectional screw of the pitch-variable actuator 842. And two ends of the bidirectional screw rod are erected on the lifting table 81 and are connected with lifting rotation, and two threaded parts are respectively connected with two sliding frames 841 in a threaded manner, so that the two sliding frames 841 are driven to move along the X axis in opposite directions or move in opposite directions.

The two box clamping mechanisms 82 are mirror mounted on two carriages 841. The pod mechanism 82 includes a holding arm 821, a holding claw 822, and a mount plate 823. The holding arm 821 is fixedly connected to the carriage 841 and extends to a side away from the elevating table 81. Two holding claws 822 are formed with a holding portion 8221 at the adjacent one end and a weight portion 8222 at the adjacent other end, and the middle portions of the holding claws 822 are each rotatably connected to the distal ends of the respective holding arms 821 by a rotation shaft provided along the Y axis. The flat plate 823 is fixedly connected to the tail end of the holding arm 821 and is positioned below the weight portion 8222. So that when the holding jaw 822 is not subjected to an external force, the holding jaw 822 is turned over by the weight portion 8222 and presses the weight portion 8222 against the plate 823, with the holding jaw 822 being horizontal. When the two clamping claws 822 clamp the carton, the balancing weight increases the friction force between the clamping part 8221 and the carton body, thereby preventing the carton body from falling off.

In addition, in order to prevent the clamping portion 8221 from damaging the carton, a chamfer is formed at the upper edge of the clamping portion 8221.

The carton is thus brought out of the lower end of the forming chamber by the carton clamping mechanism 82 and placed on the outfeed device 9. The discharging device 9 is an existing conveyor belt conveyor, and this embodiment is not described in detail.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
