Example 1:

as shown in fig. 1 and fig. 2, the present embodiment provides an automatic feeding box opening device, which includes an overturning material taking mechanism 10 fixed on a frame 50, a material forming stopper 40 and a bottom folding mechanism;

the inverted take off mechanism 10 is positioned between the bottom folding mechanism and the materials storage location and near the lower left of the materials storage location so that the inverted take off mechanism 10 can remove unformed cartons 70 from the materials storage location. The turnover material taking mechanism 10 comprises an absorbing mechanism 11 and a rotating mechanism 12, and the rotating mechanism 12 is fixedly connected with the absorbing mechanism 11, so that the rotating mechanism 12 can drive the absorbing mechanism 11 to approach the carton on the material storage place when turning. When the rotating mechanism 12 drives the suction mechanism 11 to overturn to be parallel to the carton placed in the material storage place, the rotating mechanism 12 stops rotating, the suction mechanism 11 sucks the carton, and then the carton overturns anticlockwise along the original path.

The material forming stopper 40 is disposed between the turnover material taking mechanism 10 and the material storage location, and is disposed above the turnover material taking mechanism 10, and in the process from the carton box suction to the carton box completion, the material forming stopper 40 abuts against the material forming action part 60 of the turned unformed carton box 70, and it should be noted that: here the unformed carton has been creased as required for carton formation to facilitate opening of the unformed carton 70. As shown, the material forming action 60 is on the outside edge of the fold in the unformed carton 70. The unformed carton 70 is impacted against the stock forming stop 40 by a relatively large impact force, and eventually the unformed carton opens along the crease.

Operational scenario 1 of the reverse material extraction mechanism 10:

when the unformed carton 70 needs to be taken, the turnover material taking mechanism 10 turns over to the material storage place, and when the suction mechanism 11 of the turnover material taking mechanism 10 turns over to be in contact with the unformed carton 70 (paperboard), the rotating mechanism 12 stops acting, and the suction mechanism 11 generates suction force on the paperboard, so that the paperboard is firmly attached to the suction mechanism 11.

Operational scenario 2 of the reverse material extraction mechanism 10:

when the unformed carton 70 is securely gripped by the inverting picker mechanism 10, the inverting picker mechanism 10 carries the unformed carton 70 down the original inverting path. Because the size of the carton is larger than that of the suction mechanism 11, the outer side part of the crease of the unformed carton 70 is supported against the material forming stopper 40 in the overturning process, so that the carton is opened and formed. The inverting take off mechanism 10 then inverts the formed carton to the initial position. Finally, the suction mechanism 11 removes suction to the formed carton.

In some specific embodiments, the suction device 11 includes a suction cup 111 and a fixing plate 112, the suction cup 111 is fixed on the fixing plate 112, and the fixing plate 112 is fixedly connected to the rotating device 12. When the suction cup 111 is turned to abut against the carton, the suction cup 111 pushes the carton by the impact of the turning, and pushes out the air in the cup to form vacuum, thereby sucking the carton by the action of atmospheric pressure, and when the taking is completed, the vacuum state in the suction cup 111 is released, thereby loosening the carton without adhering to the suction cup 111. Wherein the suction cups 111 are generally used in plurality.

In some specific embodiments, the rotating mechanism 12 includes a rotating mechanism 121, a first cylinder 122, a rotating rod 123, and a rotating link 124.

The cylinder body of the first cylinder 122 is vertically installed on the rack 50, the bottom of the first cylinder is provided with a base, and the base is provided with 4 screw holes for being fixedly connected with the rack 50 along the vertical direction, so that the base and the rack 50 fix the first cylinder 122 on the rack 50 in a threaded manner.

One end of the rotating mechanism 121 is fixedly connected with the absorbing mechanism 11, the end of the rotating mechanism 121 far away from the absorbing mechanism 11 is fixedly connected with the rotating rod 123, one end of the rotating connecting piece 124 is hinged to the piston of the first cylinder 122, and the other end of the rotating connecting piece is fixedly sleeved on the rotating rod 123, therefore, when the first cylinder 122 acts, the piston of the first cylinder 122 can drive the rotating rod 123 to rotate by a corresponding angle, the rotating rod 123 drives the rotating mechanism 121 to turn over when rotating, and the absorbing direction of the absorbing mechanism 11 is tangent to the rotating direction of the rotating mechanism 121.

In some specific embodiments, the rotating mechanism 121 is configured as two turning rods and a limiting rod, a horizontal position of the turning rod is provided with a matching mounting hole, and the limiting rod is sleeved in the two turning rods through the mounting hole and riveted with the two turning rods.

In this embodiment, the operation by the first cylinder 122 is divided into two states:

state 1: when the first cylinder 122 acts to eject out, the rotating rod 123 rotates by a certain angle in a direction away from the first cylinder 122 by rotating the connecting piece 124, and the rotating rod 123 rotates to drive the rotating mechanism 121 and the absorbing mechanism 11 to rotate upwards, so that the absorbing mechanism 11 can absorb unformed cartons of the storage part 24.

State 2: after the suction mechanism 11 has finished sucking the unformed cartons 70, the first cylinder 122 is contracted, and the rotation of the rotating rod 123 drives the rotating mechanism 121 and the suction mechanism 11 to rotate downwards through a certain angle of the rotating connecting piece 124 in the direction of the first cylinder 122, so that the suction mechanism 11 can suck the unformed cartons from the storage member 24.

When the material storing member 24 is taken by the turnover material taking mechanism 10, the rotation blocking mechanism 21 and the material leakage preventing mechanism 22 are used together to assist the turnover material taking mechanism 10 to take only one carton at a time, so that interference of the remaining cartons of the material storing member 24 to taking is prevented.

In some specific embodiments, the rotation blocking mechanism 21 is disposed at the front end of the discharging end of the storing mechanism 20, and the rotation blocking mechanism 21 includes a second cylinder 211, a first rotating connector 212, a limiting block 213 with a through slot, a rotating column 214, and a rotating plate 215. The cylinder body of the second cylinder 211 is fixedly connected with the frame 50, and the limiting block 213 is fixedly connected with the frame 50. One end of the first rotating connecting piece 212 is hinged to the piston of the second cylinder 211, the other end of the first rotating connecting piece is fixedly connected to the lower end of the rotating column 214, the rotating column 214 is sleeved in the limiting block 213 through the through groove of the limiting block 213, and the rotating plate 215 is fixedly connected to the upper end of the rotating column 214, so that the rotating plate 215 abuts against the carton of the storage member 24, the carton of the storage member 24 does not affect other operations, and the working reliability of the device is improved.

When the piston of the second cylinder 211 is ejected, the first rotary connector 212 pushes the rotary column 214 to rotate by a certain angle, and the rotary column 214 drives the rotary plate 215 to rotate by a corresponding angle, so as to release a carton. At this time, the turn-over reclaiming mechanism 10 has already started to turn over and reclaim material upwards, and at the moment when the turn-over reclaiming mechanism 10 reclaims a carton, the piston of the second cylinder 211 is retracted, and the rotation blocking mechanism 21 rotates in the opposite direction along the original moving path, so as to fix the remaining cartons of the magazine 24.

The support guide bar 242 is fixedly connected to the frame 50, and the support guide bar 242 is provided with a fitting member 243 capable of moving relative to the support guide bar 242. The material support bars 241 are vertically arranged with the support guide bars 242, the material support bars 241 are sleeved in the sleeve-arranged fitting members 243 on the support guide bars 242, a rib extends upwards from the outer side surfaces of the material support bars 241, and the ribs of the two material support bars 241 are used for aligning the two sides of the carton, so that the carton is placed in order in the storage member 24. The material supporting rods 241 are sleeved in the movable sleeved matching members 243, so that the distance between the material supporting rods 241 can be adjusted by the material storage member 24 according to different sizes of the cartons, so as to store different sizes of the cartons.

When the carton is taken away, the piston of the third cylinder 223 is ejected out, the second rotary connecting piece 221 is pushed to make a downward circular motion around the hinge point of the second rotary connecting piece 221 and the storage piece 24, and then the second rotary connecting piece 221 drives the anti-leakage roller 222 to rotate upward to the initial position, so that the protrusion of the anti-leakage roller 222 abuts against the carton, and the carton is prevented from leaking from the bottom.

The second cylinder 211 and the third cylinder 223 are always synchronized in motion, that is, the rotation blocking mechanism 21 and the material leakage preventing mechanism 22 are synchronized in motion. When the piston of the second cylinder 211 is ejected, the piston of the third cylinder 223 is also ejected to push the second rotary connector 221, and the second rotary connector 221 drives the protrusion of the anti-leakage roller 222 to approach the storage member 24, so as to abut against the next carton to be taken away from the storage member 24.
