Each mold box 120 is cylindrical and is matched with the beverage box in shape, and the bottom of each mold box 120 is provided with a jack, so that the beverage box can be ejected out of the mold box 120 from the bottom, and demolding is realized.

The group package conveying apparatus further includes a stopping mechanism 200 and a jacking mechanism 300, the stopping mechanism 200 is used for controlling the movement or the rest of the mold box 120, namely, controlling whether the mold box 120 continues to run along with the conveying guide rail 110, and the jacking mechanism 300 is mainly used for ejecting the beverage box blocked in the inhibited state by the stopping mechanism 200 in the mold box 120 from the lower part, so that the jacking mechanism 300 is arranged on the machine frame 100 below the conveying guide rail 110 at the upstream of the stopping mechanism 200.

Each lifting rod 340 comprises a rod body 341 and a supporting plate 342, the bottom of the rod body 341 is fixed on the lifting plate 320, the supporting plate 342 is fixed on the top of the rod body 341, and as the lifting rod 340 pushes the beverage box out of the mold box 120 from the bottom, the supporting plate 342 is in contact with the bottom of the beverage box, the contact area is increased, and the beverage box is prevented from being pushed through by the lifting rod 340 in the jacking process.

Because the number of the lifting rods 340 on the lifting plate 320 is constant, as shown in fig. 6, the lifting rods 340 are arranged in five rows and eight columns at present, but the packing number of different products is different, that is, some products do not need to suck eight rows of beverage cups at a time, and at this time, the number of the beverage cups to be lifted at a time needs to be adjusted. Therefore, the jacking mechanism 300 further comprises a pair of slide rails 350 and a traverse driving mechanism 360, the pair of slide rails 350 is fixed on the jacking frame 310, and is arranged along the conveying direction of the mold box 120, a moving plate 370 is arranged on the slide rail 350 in a sliding way, the moving plate 370 is driven by the transverse moving driving mechanism 360 to move along the slide rail 350, the lift actuator 330 is fixed to the moving plate 370, so that the effective lift amount of the lift rod 340 can be controlled, as shown in fig. 5, if the distance between two adjacent rows of lift pins 340 is taken as a standard distance, in the state shown in the figure, the traverse driving mechanism 360 controls the lifting plate 320 to move three standard distances towards the moving direction of the mold box 120, that is, three rows of lifting rods 340 are located behind the blocking mechanism 200, that is, three rows of lifting rods 340 will not work, and after the lifting driving mechanism 330 drives the lifting plate 320 to lift, five rows and five columns of beverage boxes are lifted from the mold box 120.

Further, in order to more accurately control the traverse distance, the traverse driving mechanism 360 includes a traverse driving motor 361, a traverse lead screw 362 and a traverse lead screw sleeve 363, the traverse driving motor 361 is fixed on the jacking frame 310, the traverse lead screw 362 is rotatably connected on the jacking frame 310, the axial direction of the traverse lead screw is parallel to the length direction of the slide rail 350, the traverse driving motor 361 drives the traverse lead screw 362 to rotate, the traverse lead screw sleeve 363 is in threaded connection with the traverse lead screw 362, the moving plate 370 is fixedly connected with the traverse lead screw sleeve 363, so that the moving plate 370 is driven by the rotation of the traverse lead screw 362, and the traverse lead screw 362 is matched with the traverse lead screw sleeve 363 to accurately control the moving distance of the moving plate 370, thereby ensuring that the jacking rod 340 can be aligned with the jack of the mold box 120 after the moving plate 370 moves.

In the process that the jacking driving mechanism 330 drives the jacking plate 320 to ascend and descend, the jacking rod 340 needs to be ensured to be in a straight-up and straight-down motion mode, the moving plate 370 is generally rectangular, the four corners of the moving plate 370 are respectively fixed with the first sliding sleeves 380, the four corners of the jacking plate 320 are provided with the first sliding bars 390 corresponding to the first sliding sleeves 380, and the moving track of the jacking plate 320 is limited by the cooperation of the first sliding sleeves 380 and the first sliding bars 390, so that the jacking rod 340 is ensured to be capable of being straight-up and straight-down.

The blocking mechanism 200 mainly has the function of blocking the mold box 120 on the conveying guide rail 110 so that the mold box 120 does not move along with the conveying guide rail 110 any more, thereby ensuring that the jacking rod 340 can smoothly penetrate into and move out of the mold box 120, the blocking mechanism 200 comprises a blocking frame 210, a blocking plate 220 and a blocking driver 230, the blocking frame 210 is in a door shape, spans over the conveying guide rail 110 and is fixed on the rack 100, the blocking driver 230 is fixed on a cross beam of the blocking frame 210, and the blocking plate 220 is driven by the blocking driver 230 to block on the running line of the mold box 120. The two second sliding sleeves 240 are further fixed on the blocking frame 210, the two second sliding sleeves 240 are respectively located on two sides of the blocking driver 230, the blocking plate 220 is connected with two second sliding rods 250, the two second sliding rods 250 are in sliding fit with the corresponding second sliding sleeves 240, the blocking driver 230 drives the cylinder for blocking by utilizing the fit of the second sliding rods 250 and the second sliding sleeves 240, the blocking driving cylinder comprises a cylinder body 231 and a piston 232, the cylinder body 231 is fixed on the blocking frame 210, the piston 232 is fixedly connected with a connecting plate 260, the connecting plate 260 is fixedly connected with the two second sliding rods 250, the driving force of the blocking driver 230 is better transmitted to the two second sliding rods 250 through the connecting plate 260, and the pushing force is transmitted to the blocking plate 220 through the second sliding rods 250. The movement track of the limiting blocking plate 220 can only move along a straight line direction, and the limiting blocking plate 220 is perpendicular to the conveying direction of the die box 120, so that the die box 120 is kept at uniform positions after being blocked, the sucking disc mechanism can conveniently suck the die box, and the limiting blocking plate can be distributed and matched with the jacking rod 340 of the jacking mechanism 300. For the reverse operation of the blocking plate 220, the second sliding rod 250 and the blocking driver 230 can be vertically downward perpendicular to the moving direction of the mold box 120, but this way can make the second sliding rod 250 and the blocking driver 230 bear large lateral force, which easily causes the second sliding rod 250 and the blocking driver 230 to deform, and affects the normal operation of the blocking plate 220, so the invention sets the reverse operation of the blocking plate 220 to be obtuse angle with the moving direction of the mold box 120, i.e. obliquely inserts the blocking mold box 120, so that the lateral force of the second sliding rod 250 and the blocking driver 230 can be increased, and the lateral deformation range of the second sliding rod 250 and the blocking driver 230 can be reduced.

When the automatic lifting device is used, the number of beverage boxes which need to be sucked up in sequence is determined according to the boxing requirement, then the transverse moving driving motor 361 drives the transverse moving screw 362 to transfer, the driving moving plate 370 transversely moves to a proper distance, and the number of the beverage boxes which can be lifted up by one-time lifting is controlled to be equal to the number of the beverage boxes which can be sucked up. When the machine is formally started to operate, the conveying guide rail 110 drives the mold box 120 to move, the blocking driver 230 drives the blocking plate 220 to obliquely block the mold box 120 downwards, the mold box 120 is blocked by the blocking plate 220, the mold box 120 is in a static state relative to the machine frame 100, at the moment, the jacking driving mechanism 330 is started to drive the jacking plate 320 to drive the jacking rod 340 to move upwards, the jacking rod 340 is inserted into the mold box 120 from a jack at the bottom of the mold box 120 to jack up the beverage box from the bottom, so that the beverage box is separated from the mold box 120, then the suction cup mechanism descends from the upper part to suck the beverage box, after the suction cup sucks the beverage box, the jacking driving mechanism 330 drives the jacking plate 320 to descend, the jacking rod 340 withdraws from the mold box 120, the blocking driver 230 drives the blocking plate 220 to recover, the conveying guide rail 110 drives the mold box 120 to continue to move forwards, after the empty mold box 120 is moved out of the lower part of the blocking device, the blocking driver 230 is started again to enable the blocking plate 220 to block the mold box 120 with the beverage box, the above process is repeated, and the operation is repeated in a reciprocating manner. After the grouped packaging box conveying device is adopted, the beverage box can be separated from the die box 120 by the jacking mechanism 300 before the suction disc mechanism sucks the beverage box, so that the friction force between the beverage box and the die box 120 is eliminated, the phenomenon that the suction disc mechanism pulls the beverage box after sucking the beverage box is avoided, and the sucking process is smoother.
