[0015] In order to protect the suction cup and avoid damaging the paper jam on the packaging box cover, the suction cup mechanism 1 includes a plurality of vacuum suction cups 101 and a suction cup plate 102. The plurality of vacuum suction cups 101 are installed on the suction cup plate 102. The suction cup plate 102 is connected to the four guide sleeves 104 through four guide rods 103. The four guide sleeves 104 are arranged on a pressing plate 105. The four guide rods 103 are sleeved with compression springs 106. The two ends of the compression springs 106 respectively abut against the suction cup plate 102 and the pressing plate 105. The pressing plate 105 is fixedly connected to a connecting plate 107 arranged at the output end of the double-rod lifting cylinder 2. A limited annular platform 108 is arranged after the four guide rods 103 extend out of the pressing plate 105. By arranging the compression springs, a protective effect of buffering the downward pressure can be played during the downward pressure process to avoid damage to the vacuum suction cup and damage to the paper jam on the box cover caused by excessive downward pressure and impact. In addition, the elastic buffer can more stably realize vacuum adsorption and stably adsorb on the paper jam on the box cover, which is convenient for stable adsorption and transmission to the conveyor belt.

[0016] In order to realize the automatic opening of the mechanism for pressing the stacked box cover jammed paper, a vertical cantilever rod 109 is provided on the feeding side of the bottom of the pressing plate 105, and the end of the vertical cantilever rod 109 is rotatably connected to a roller 110, and the end of the horizontal cantilever rod 111 is provided with a downward bending portion to facilitate the contact of the roller therewith, and the roller 110 can touch the horizontal cantilever rod 111, and the horizontal cantilever rod 111 is connected to the horizontal arm of the V-shaped bending swing arm 112, and the corner of the bending swing arm 112 is rotatably connected to the mounting plate 10 provided at the bottom of the cylinder frame 9 through a horizontal rotating shaft, and the inclined arm of the bending swing arm 112 is hinged to the pulling arm 113, and the end of the pulling arm 113 on the discharge side is hinged to an upper corner of a triangular pressing head 114, and a lower corner of the pressing head 114 is hinged to the horizontal hinged seat plate 1 15, a horizontal hinged seat plate 115 is horizontally fixedly connected to the bottom of the mounting plate 19, a pressing platform 116 is set at the third corner of the pressing head 114, and the pressing can be pressed on the top of the feeding side of the stacked packaging box cover jam 6, and the inclined arm end of the bending swing arm 112 is also connected to the horizontal hinged seat plate 115 near a corner of the lower side of the pressing head 114 through a reset spring 117, and an avoidance gap 118 is set at the suction cup plate 102 facing the roller 110, and the pressing plate is driven down by the double-rod lifting cylinder. When the roller contacts the cantilever rod and presses it down, the bending swing arm 112 is driven to swing, and then the bending swing arm 112 pulls the pulling arm to move. After the pulling arm moves to the left, it pulls the pressing head 114 to release the compressed box cover jam, and adsorbs the box cover jam under the adsorption action of the adsorption mechanism.

[0017] In order to realize single-layer ascending control, an electric lifting storage rack 10 is arranged on the storage rack 5, and the storage rack 10 includes a lifting plate 1001, and the two sides of the lifting plate 1001 are respectively connected to the two side wall panels of the door frame 20 through two pairs of lifting slider guide rail pairs 1002. The door frame 20 is fixedly connected to the bottom of the storage rack 5, and two side wall panels are installed with two chain transmission mechanisms 1003. The single-side chain of each chain transmission mechanism 1003 is fixedly connected to the side of the storage rack 10 through a clamping piece, and the chains on both sides rotate synchronously. The lifting plate 1001 is provided with a strip hole 1004, and also includes a plurality of limit rods 1005 arranged symmetrically on the left and right and arranged at the discharge end. The lower end of the limit rod 1005 is fixedly connected to the bottom plate of the storage rack 5, and the upper end movably passes through the strip hole 1004 and forms a storage for placing the box cover with the lifting plate 1001. The storage frame structure can store two symmetrically placed integrated box cover paper jams (the two sheets are not cut off). Through the storage rack of this structure, the box cover paper jams can be quickly stored. There are left and right side notches on the box cover paper jams. The notches are inserted into the limit card to absorb and lift the box cover paper jams. It needs to be lifted to a distance above the upper end of the limit rod to avoid damaging the box cover paper jams. The limit rods 1005 on the left and right sides are fixedly connected to an auxiliary support plate 1006. The auxiliary support plate 1006 is provided with a limit slot. The limit rod 1005 is inserted into the limit groove, and the auxiliary support plate 1006 is cantileveredly connected to the belt frame of the conveyor belt 8 through the L-shaped cantilever seat 1007. The short end of the cantilever seat 1007 is vertically fixedly connected to the end of the auxiliary support plate 1006, and the long end is horizontally fixedly connected to the belt frame of the conveyor belt 8. The auxiliary support plate 1006 is arranged to provide auxiliary limit support for the upper end of the vertically connected limit rod, so as to avoid inaccurate positioning of the top of the stacked too high jammed paper due to shaking, thereby affecting the precise position transmitted to the conveyor belt.

[0018] In order to improve the adsorption and stratification effect and avoid the adhesion of two adjacent stacked box cover paper jams, nozzles 11 are arranged on both sides of the pressing head 114. The nozzles 11 are connected to the jet valve 13 through the universal joint tube 12. The jet valve 13 is installed on the cantilever beam 4. The jet valve 13 is connected to a pressurized air source. After releasing the pressing head, the nozzle is used to blow air to separate the two adjacent box cover paper jams to avoid the adsorption of multiple paper jams due to adhesion. The universal joint tube can quickly realize the rapid orientation positioning of the nozzle, find the best jet position adjustment, and adapt to the rapid conversion and adjustment of box cover paper jams of different sizes.

[0019] When a paper jam occurs and is transported to the conveyor belt, the jammed paper on the box cover is suspended by an adsorption mechanism and then transported to the conveyor belt. However, the jammed paper end of the box cover cannot be quickly attached to the conveyor belt for transportation after being suspended on the side of the conveyor belt, which affects the entry stability. In this regard, a guide pressing roller 14 is suspended on the discharge side of the cantilever beam 4, and the four corners of the wheel frame top plate of the guide pressing roller 14 are hung on the cantilever beam 4 through four suspension ropes 15. The guide pressing roller 14 is located above the feed end of the conveyor belt 8 and the lowest part of the wheel surface of the guide pressing roller 14 maintains a 1-1.5mm distance from the top surface of the conveyor belt 8. By setting a guiding guide pressing roller, it can The box cover jam at one end is quickly introduced into the limiting slot on the conveyor belt and the roller presses it onto the conveyor belt for transportation, so that it can be smoothly transported after the suction cup is released, and the stability of the box cover jam entering the conveyor belt is improved to avoid the end of the box cover jam hitting the limiting structure on the conveyor belt and causing damage. Flexible paper sheets are also provided on both sides of the entry end of the limiting slot to avoid wear during the lowering process of the front end of the jam. The guide pressing roller connected by the flexible rope can play a buffering role to avoid the box cover jam caused by excessive force and damage due to hard connection. Under the gravity of the guide pressing roller, the box cover jam is kept pressed tightly with the conveyor belt.

[0020] In order to safely deliver the cardboard on the packaging box cover and avoid it from being scratched on the limit rod, a flexible paper baffle 16 bent toward one side of the conveyor belt is provided on the storage rack 10 below the guide pressing roller 14. The flexible paper baffle can play an auxiliary supporting transition role when one end of the cardboard on the box cover that is adsorbed and pushed (the end before entering and the end hanging after the suction cup puts down the cardboard) is suspended and bent, so as to avoid the decorative smooth surface at the bottom of the cardboard on the box cover from being scratched against the top of the limit rod to cause damage or scratches, thereby improving the transportation safety, and cooperating with the guide pressing roller, it can play a better role in directional movement. A curved guide flexible cardboard 17 is overlapped on one side of the output of the guide pressing roller 14, and the guide flexible cardboard 17 is connected to a pressing block 18 provided on the conveyor belt 8. The pressing block 18 is fixedly connected to the belt frame of the conveyor belt 8 through a frame and maintains a gap with the belt. This structure can play a guiding role in introducing the upwardly bent cardboard under the pressing block 18, so as to avoid bending and colliding upward on the pressing block after passing through the guide pressing roller 14, causing the cardboard to bend.

[0021] Principle of use: When in use, the stacked box cover paper jams are placed in the storage frame structure, and the adsorption mechanism is controlled by the lifting cylinder and the pushing cylinder to adsorb the box cover paper jams toward the feeding side. After adsorption, the lifting height is higher than the limit rod, and the pushing mechanism is controlled to move the adsorbed and lifted box cover paper jams forward, and the head end of the box cover paper jams is embedded in the gap between the guide pressing roller and the conveyor belt.
