The output end of the electric push rod 3 is connected to a bag expansion mechanism 4. The bag expansion mechanism 4 includes a C-shaped plate 401 connected to the output end of the electric push rod 3. A chute 402 is opened on the inner side of the upper end of the C-shaped plate 401. One side of the C-shaped plate 401 is connected to a stepping motor A 403. The output end of the stepping motor A 403 is connected to a rotating rod 404. Two symmetrically arranged threaded grooves are opened on the outer peripheral side of the rotating rod 404. The rotating rod 404 is threadedly connected to two symmetrically arranged moving blocks 405. The lower end of the moving block 405 is connected to an opening block 406. One end of the moving block 405 away from the opening block 406 is connected to a slider 407. The slider 407 is slidably connected to the chute 402. A bag mouth opening mechanism 5 is provided in the middle of the lower end of the C-shaped plate 401.
[0021] Specifically, the bag mouth opening mechanism 5 includes a contact plate 501 connected to the middle of the lower end of the C-shaped plate 401. A fixed block 502 is connected to the lower end of the contact plate 501. Through holes 508 are formed through both sides of the fixed block 502. An arc-shaped groove 507 is formed at the lower end of the fixed block 502. The arc-shaped groove 507 is set at 90°. A stepping motor B503 is connected to the middle of the lower end of the fixed block 502. The output end of the stepping motor B503 is connected to a rotating shaft 504. The rotating shaft 504 is connected to a rotating plate 505. A guide post 506 is connected to the upper end of the rotating plate 505. The guide post 506 is slidably connected to the arc-shaped groove 507. The mounting assembly 2 includes a mounting plate 201 connected to the U-shaped plate 1. Two symmetrically arranged mounting screw holes 202 are formed at the upper end of the mounting plate 201. The rotating rod 404 passes through the through hole 508. The outer diameter of the rotating rod 404 is smaller than the inner diameter of the through hole 508. The rotating rod 404 is rotatably connected to the C-shaped plate 401 through a bearing.

[0022] Working principle: First, power is supplied to the electric push rod 3. At this time, the output end of the electric push rod 3 indirectly drives the bag mouth opening mechanism 5 to move downward. At this time, the rotating plate 505 is inserted into the bellows bag. Next, the power supply to the electric push rod 3 is cut off. Next, power is supplied to the stepping motor B503. At this time, the output end of the stepping motor B503 drives the rotating shaft 504 to rotate, thereby driving the rotating plate 505 to perform a rotating action. At this time, the rotating plate 505 drives the guide post 506 to slide in the arc-shaped groove 507. When the rotating plate 505 rotates 90°, at this time, the guide post 506 rotates 90°. At this time, the guide post 506 is limited. At this time, the power supply to the stepping motor B503 is cut off. Next, the power supply to the electric push rod 3 is supplied again, and the power supply to the stepping motor A403 is supplied. At this time, the output end of the stepping motor A403 drives the rotating rod 404 to rotate, thereby driving the moving block 405 to move. At this time, the moving block 405 drives the opening block 406 to perform a two-side moving action. At this time, the moving block 405 drives the slider 407 to slide in the chute 402. At this time, the bellows bag is opened. The utility model realizes that the middle of the bellows bag can be opened first and then the two-side opening action can be performed, which is convenient for opening the bellows bag and improves the work efficiency.
