[0066] The working process of the automatic bag opening mechanism is:

[0067] When the packaging bag 3 is in Figure 1When in the position shown, the bag cutting drive motor 1.1 is energized, and the output shaft of the bag cutting drive motor 1.1 drives the active wheel 1.141 to rotate; the active wheel 1.141 drives the first driven wheel 1.142 and the second driven wheel 1.143 to rotate respectively; thereby driving the bidirectional screw rod 1.2 to rotate; thereby driving the left transmission component fixing plate 1.13 and the right transmission component fixing plate 1.16 and the parts fixed thereon to move toward each other. During the process of moving toward each other, since the back knife assembly 1.8 and the knife assembly 1.10 thereon are respectively fixed with magnets I1.84 and magnets II1.107, due to the magnetic attraction of the magnets, the magnet fixing block I1.86 and the magnet fixing block II1.104 will be moved along the plug screw I1.81 and the plug screw respectively. The nail III 1.101 speeds up the speed of moving toward each other, and then is sucked together first, clamping the lower end of the packaging bag 3 for preliminary fixation; when the bag cutting drive motor 1.1 continues to move, the convex block 1.85 and the concave block 1.105 move toward each other until the concave and convex parts coincide with each other, and therefore the back knife assembly 1.8 and the knife assembly 1.10 can be kept in the same horizontal plane and kept in a clamped state. The bag cutting drive motor 1.1 continues to move, the back knife assembly 1.8 and the knife assembly 1.10 continue to maintain a central position and do not move, while the left transmission assembly fixing plate 1.13 and the right transmission assembly fixing plate 1.16 continue to move toward each other, and at this time the left transmission assembly fixing plate 1.13 and the right transmission assembly fixing plate 1.16 are respectively connected to the back knife assembly 1.8 and The knife and fork assembly 1.10 achieves relative movement; when the movement continues, until (roller I 1.87 hits the right slope guide block 1.7 and moves upward along the slope relative to the right slope guide block 1.7, that is, the back knife assembly 1.8 moves vertically upward relative to the right knife bar assembly 1.9, roller II 1.106 hits the left slope guide block 1.12 and moves upward along the slope relative to the left slope guide block 1.12, that is, the knife and fork assembly 1.10 moves vertically upward relative to the left knife bar assembly 1.17. This part of the action is intended to squeeze the material in the packaging bag 3 from the bottom upward to form a vacuum material-free part, which is convenient for cutting the packaging bag 3 at this position later. At the same time, the serrated blade 1.113 in the blade assembly 1.11 pushes the packaging bag 3 against When the movement continues, the left transmission assembly fixing plate 1.13 respectively presses against the screw IV 1.111 of the blade assembly 1.11, thereby indirectly pressing against the serrated blade 1.113 and causing it to move rightward relative to the cutting assembly 1.10, so that the serrated blade 1.113 passes through the packaging bag 3 and cuts the packaging bag 3; when the induction plate I 1.15 installed on the left transmission assembly fixing plate 1.13 moves to the second sensor 2.16, the second sensor 2.16 is triggered, and the bag cutting drive motor 1.1 stops rotating. (Then, the bag cutting drive motor 1.1 starts to rotate in the reverse direction, and the left transmission assembly fixing plate 1.13 stops rotating.)13 and the components fixed thereto begin relative motion with the right transmission assembly fixing plate 1.16 and the components fixed thereto. The serrated blade 1.113 retreats first due to the rebound force of the compression spring on the plug screw IV 1.111. As this motion continues, roller I 1.87 moves downward along the slope of the right ramp guide block 1.7, and roller II 1.106 moves downward along the slope of the left ramp guide block 1.12. Subsequently, the interlocking protrusions 1.85 and recesses 1.105 on the back knife assembly 1.8 and the cutter assembly 1.10 separate, until the induction plate I 1.15 moves to the position of the first sensor 2.15, at which point the bag cutting drive motor 1.1 stops. During the reverse rotation of the drive motor I 1.1 until it stops, at the moment magnet I 1.84 and magnet II 1.107 separate, the material in the packaging bag 3 begins to freely fall downward.

[0068] When drive motor I 1.1 finally stops, sensor plate II 2.17 on the extruder mechanism 2 is located at sensor IV 2.20, and the cam followers 2.21 on both sides of the concave back plate 2.1 are located at the top of the concave back plate 2.1 groove. At this time, when drive motor I 1.1 stops, drive motor II 2.13 begins to rotate, driving the connecting plate 2.8 downward through the vertical screw rod 2.11 connected to it. At the same time, the cam followers 2.21 move along the groove track near the oblique edge and center of the ratchet block 2.2. As the cam follower 2.21 moves to the bottom, the sensing piece II 2.17 moves to the position of the third sensor 2.19, and the driving motor II 2.13 stops. Due to the compression spring built into the horizontal guide rod 2.5, the cam follower 2.21 moves along the bottom of the groove to the side away from the center. The arm fixing plate 2.4 and the components above it move outward and also move to the side away from the center. The material inside the packaging bag 3 has been squeezed out through the cut. 30 seconds later, the system immediately starts to reverse its motion, moving the cam follower 2.21 upward along the groove track away from the center. When the cam follower 2.21 contacts the ratchet block 2.2, it pushes the ratchet block 2.2 away and continues to move upward along the groove track until the sensor plate 2.17 moves to the position of the fourth sensor 2.20 again. At this time, the cam follower 2.21 has also moved to the top of the groove, and the drive motor 2.13 stops.

[0077] A grabbing sensor 7.5 and a discharging sensor 7.4 are fixedly installed in the hook bracket 7.3. The grabbing sensor 7.5 and the discharging sensor 7.4 are electrically connected to the hook rotating component. When the rotating hook 7.6 needs to remove the material on the picking and throwing mechanism 7, the rotating motor 7.8 drives the rotating hook 7.6 to rotate to the grabbing sensor 7.5, the rotating motor 7.8 stops rotating, the material on the picking and throwing mechanism 7 is removed, and the rotating shaft of the rotating motor 7.8 is locked and cannot rotate relative to each other; when the rotating hook 7.6 unloads the material, the rotating motor 7.8 drives the rotating hook 7.6 to rotate to the discharging sensor 7.4, the rotating motor 7.8 stops rotating, and the material is unloaded.

[0078] The automatic storage and retrieval device also includes a material storage piece 3, which has a material insertion hole 3.1 dug inside. The material insertion hole 3.1 is adapted to the chain hook 6.2 and the rotating hook 7.6, and the material storage piece 3 is hung on the chain hook 6.2 or the rotating hook 7.6 through the material insertion hole 3.1.

[0079] The working principle of the present invention is that when the moving motor 7.1 is energized, the material taking and throwing mechanism 7 is moved to a designated set of conveying and storage mechanisms 6 through the screw rod 7.2, and the moving motor 7.1 stops. At this time, the conveying motor 6.6 starts, driving the chain to rotate, and the bag of stored material 3 closest to the material taking and throwing mechanism 7 is inserted into the end of the rotating hook 7.6 through the material insertion hole 3.2. Since each rotating hook 7.6 is equipped with an induction sheet 6.10, when the next induction sheet 6.10 moves to the sensor 6.9 and triggers the sensor 6.9, the conveying motor 6.6 stops rotating. At this time, the stored material 3 has been separated from the chain hook 6.2 and entered the corner of the rotating hook 7.6, waiting for the next operation instruction. When the command is given, the moving motor 7.1 is energized, and the material taking and throwing mechanism 7 is moved to the specified position through the screw rod 7.2, and then the rotating motor 7.8 is energized to drive the rotating hook 7.6 to rotate. When the rotating hook 7.6 passes the grabbing sensor 7.5, the rotating motor 7.8 is powered off. During this rotation process, the stored material 3 has slid down along the downward inclined end of the rotating hook 7.6, and then the rotating motor 7.8 rotates in the opposite direction. When it passes the unloading sensor 7.4, it stops rotating and waits for the next instruction to complete a working process.
