The stepper motor 72 of the device 7 starts to rotate, and the rotation of the stepper motor 72 drives the rotating table 76 to rotate 180 degrees. When the air suction plate 29 moves to the position of the laser sensor 512, the laser sensor 512 transmits the sensed signal to the PLC control module, and the PLC control module sends a control command to stop the action to the servo motor 510. At this time, the air suction plate 29 presses the limiting plate 1364 of the elastic limiting mechanism 136 of the packaging bag placement frame 13, and moves to the inside of the placement frame 132 until it penetrates into the inside of the placement frame 132 of the packaging bag placement frame 13. The air suction plate 29 sucks up a packaging bag, and then the PLC control module delays 0.5 seconds, a control instruction to start counterclockwise rotation is sent to the servo motor 510, and the screw rod 56 starts to rotate counterclockwise. Similarly, with the cooperation of the screw rod 56, the slider three 58 and the slider four 59, the slider three 58 and the slider four 59 slide towards each other. When the air suction plate 29 moves to the left and leaves the placement frame 132, the packaging bag adsorbed on the air suction plate 29 is separated from the middle position of the elastic limiting mechanism on the left and right fixed rods 134. At the same time, the PLC control module delays sending a control instruction to the stepper motor 72 of the rotating device 7 to rotate 180 degrees again. At this time, the air suction plate 29 rotates to the left position of the air hole. When the slider three 58 and the slider four 59 move towards each other to the limit position, the PLC control module sends a stop control instruction to the servo motor 512 of the same direction position device 5. At this time, the air suction plate 1 8 and the air suction plate 9 are in a close state. The air suction plate 9 sucks one side of the packaging bag, and the air suction plate 1 8 sucks the other side of the packaging bag at the same time. Then the PLC control module After a delay, the control command for the servo motor 510 to rotate clockwise again is sent. The slider 3 58 and the slider 4 59 move in opposite directions. When the air suction plate 1 8 and the air suction plate 9 move to the length of the diameter of the packaging bag, the PLC control module sends a stop control command to the servo motor 510. At this time, the packaging bag is in an open state. At the same time, the PLC control module sends a start control command to the servo motor of the linear module 1 2 and the servo motor of the linear module 2 3. At this time, the slider 1 22 installed on the linear module 1 2 moves to the front side, and the slider 2 32 on the linear module 2 3 moves upward, and drives the synchronous displacement device 5 to move upward. When the slider 1 22 moves forward to the limit position, the synchronous displacement device 5 is at the lower part of the dispensing machine discharge port. When the slider 2 32 moves upward to the limit position, the opened packaging bag just penetrates into the dispensing machine discharge port position, thus completing the automatic opening and pushing action of the packaging bag for casting material packaging.

[0018] The beneficial effects of the utility model are as follows: through the joint action of the linear module 1, the linear module 2, the synchronous displacement device, the rotating device, the air suction plate 1, the air suction plate 2 and the packaging bag placement frame, the automatic opening and pushing of the packaging bag is realized, which replaces the manual operation of opening and aligning the packaging bag, improves the work efficiency, and solves the problem that the complex mechanical opening and pushing mechanism is prone to malfunction.

[0035] like Figure 1-5As shown in the figure, the working process of the automatic opening and pushing device for packaging bags for casting material packaging is as follows: first, the packaging bags are neatly folded and placed in the placement frame 132 from the placement port 133 at the upper part of the packaging bag placement frame 13 for standby use; then, the exhaust fan and the solenoid valve are turned on, and at this time, the air suction plate 1 8 and the air suction plate 2 9 are in a negative pressure state; then, the servo motor 510 of the synchronous displacement device 5 is turned on, and under the clockwise rotation of the servo motor 510, the coupling 511 and the screw rod 56 are driven to rotate clockwise, and under the rotation of the screw rod 56, the air suction plate 1 8 and the air suction plate 2 9 are synchronized and moved in opposite directions through the cooperation with the slider 3 58 and the slider 4 59, and at the same time, the rotation is turned on. The stepper motor 72 of the device 7 starts to rotate, and the rotation of the stepper motor 72 drives the rotating table 76 to rotate 180 degrees. When the air suction plate 29 moves to the position of the laser sensor 512, the laser sensor 512 transmits the sensed signal to the PLC control module, and the PLC control module sends a control command to stop the action to the servo motor 510. At this time, the air suction plate 29 presses the limiting plate 1364 of the elastic limiting mechanism 136 of the packaging bag placement frame 13, and moves to the inside of the placement frame 132 until it penetrates into the inside of the placement frame 132 of the packaging bag placement frame 13. The air suction plate 29 sucks up a packaging bag, and then the PLC control module delays 0.5 seconds, a control instruction to start counterclockwise rotation is sent to the servo motor 510, and the screw rod 56 starts to rotate counterclockwise. Similarly, with the cooperation of the screw rod 56, the slider three 58 and the slider four 59, the slider three 58 and the slider four 59 slide towards each other. When the air suction plate 29 moves to the left and leaves the placement frame 132, the packaging bag adsorbed on the air suction plate 29 is separated from the middle position of the elastic limiting mechanism on the left and right fixed rods 134. At the same time, the PLC control module delays sending a control instruction to the stepper motor 72 of the rotating device 7 to rotate 180 degrees again. At this time, the air suction plate 29 rotates to the left position of the air hole. When the slider three 58 and the slider four 59 move towards each other to the limit position, the PLC control module sends a stop control instruction to the servo motor 512 of the same direction position device 5. At this time, the air suction plate 1 8 and the air suction plate 9 are in a close state. The air suction plate 9 sucks one side of the packaging bag, and the air suction plate 1 8 sucks the other side of the packaging bag at the same time. Then the PLC control module After a delay, the control command for the servo motor 510 to rotate clockwise again is sent. The slider 3 58 and the slider 4 59 move in opposite directions. When the air suction plate 1 8 and the air suction plate 9 move to the length of the diameter of the packaging bag, the PLC control module sends a stop control command to the servo motor 510. At this time, the packaging bag is in an open state. At the same time, the PLC control module sends a start control command to the servo motor of the linear module 1 2 and the servo motor of the linear module 2 3. At this time, the slider 1 22 installed on the linear module 1 2 moves to the front side, and the slider 2 32 on the linear module 2 3 moves upward, and drives the synchronous displacement device 5 to move upward. When the slider 1 22 moves forward to the limit position, the synchronous displacement device 5 is at the lower part of the dispensing machine discharge port. When the slider 2 32 moves upward to the limit position, the opened packaging bag just penetrates into the dispensing machine discharge port position, thus completing the automatic opening and pushing action of the packaging bag for casting material packaging.
