Description

Technical Field

[0001] This utility model relates to the field of box opening structure, specifically a pre-opening suction cup mechanism for box adsorption. Background Technology

[0002] Existing cartoning machines, when handling boxes of similar width and height, typically use passive blocks or box conveyor clamps to impact and open the boxes. For example, Chinese patent CN115432235A discloses a pre-opening mechanism for an intermittent cartoning machine, including a box-picking rod mechanism, a pre-opening arm, a rotating disk, and a main shaft. The box-picking rod mechanism includes a suction cup, a suction cup arm, a suction cup arm central shaft, and a suction cup arm wheel. The rotating disk is mounted on the main shaft, which also has a main shaft center wheel and a main shaft front wheel. The rotating disk, main shaft center wheel, and main shaft front wheel rotate around the main shaft. The rotation of the main shaft center wheel drives the rotation of the suction cup arm wheel. The suction cup is fixed to the suction cup arm central shaft via the suction cup arm, and the suction cup arm central shaft is fixed to the center of the suction cup arm wheel. The rotation of the main shaft front wheel drives the pre-opening arm to rotate.

[0029] The box-removing transmission 12 includes a box-removing motor 121, a motor connecting rod 122, a motor connecting plate 123, a box-removing transmission shaft 124, and a box-removing outer shell 125. The box-removing motor 121 is disposed inside the box-removing outer shell 125. One end of the motor connecting rod 122 is movably connected to the motor connecting plate 123, and the other end is connected to the output shaft of the box-removing motor 121. One end of the box-removing transmission shaft 124 is connected to the motor connecting plate 123, and the other end passes through the connecting rod seat 111 and connects to the connecting rod A112. The box-opening transmission 21 includes an opening motor 211, an opening conveyor belt assembly 212, an opening lifting device 213, an opening guide rail 214, an opening cam 215, an opening cam seat 216, an opening negative pressure seat 217, and an opening fixing plate 218. The opening motor 211 is drivenly connected to the opening conveyor belt assembly 212, and the opening fixing plate 218 is drivenly connected to the opening guide belt assembly 212. Plate 218 is movably connected to the box-opening conveyor belt assembly 212. The box-opening lifting device 213 is connected to the box-opening guide rail 214. The box-opening cam 215 is disposed inside the box-opening guide rail 214. One end of the box-opening cam seat 216 is connected to the box-opening cam 215, and the other end is connected to the box-opening suction rod 222. The box-opening negative pressure seat 217 is movably disposed on the box-opening suction rod 222. The box-opening suction rod 222 is provided with a suction cup, and the suction cup is negatively connected to the box-opening negative pressure seat 217 through the inside of the box-opening suction rod 222.

[0030] Working mode: The box-picking motor 121 drives the motor connecting rod 122 to move the motor connecting plate 123. The angle of movement of the motor connecting plate 123 is transmitted to the connecting rod A112. The rotation of the connecting rod A112 drives the connecting rod C115, the transition rod 114, and the connecting rod B113 to move together, forming a linkage mechanism. This ensures that the box-picking negative pressure seat 118 moves back and forth at the obliquely upward (usually the material is supplied at the obliquely upward) and the box-opening suction component 22 below. During this process, the suction cup on the box-picking negative pressure seat 118 is continuously supplied with suction through the box-picking pressure supply source 116. When the box moves to the position of the suction cup on the box-opening positioning suction rod 221, the suction cup on the box-picking negative pressure seat 118 stops suction, and the box-opening positioning suction rod 221 then... The suction cup on 21 begins to adhere, and then the box-removing motor 121 drives the box-removing connecting rod 11 back to the initial position at the upper angle. The box-opening lifting device 213 rises, driving the box-opening cam 215 and the box-opening cam seat 216 in the box-opening guide rail 214 to rotate the box-opening suction rod 222 toward the box body. The box-opening negative pressure seat 217 draws air, causing the suction cup on the box-opening suction rod 222 to adhere to the box body. Then the box-opening lifting device 213 descends, and the box-opening suction rod 222 rotates back to its original position, so that the box body opens at 90°. The box-opening motor 211 rotates, driving the box-opening fixing plate 218 to move horizontally through the box-opening conveyor belt group 212, transferring the box body to the next process and then resetting it. The above steps are repeated in this way.
