DETAILED DESCRIPTION

[0018] like Figures 1 to 5As shown, this embodiment provides a valve-mouth packaging bag shooting mechanism, including a bag picking device 5, a horizontal guide device 35 and a bag shooting device 6. The bag picking device 5 is driven by a cam device 7. The electric motor 8 drives the cam device 7 to rotate, and the valve bag 4 can be periodically sucked. The bag picking device 5 and the horizontal guide device 35 work together. The valve of the valve-mouth packaging bag 4 sucked by the bag picking device 5 is opened, and the valve of the packaging bag is kept open in the horizontal guide device 35 until the bag shooting device 6 shoots the valve-mouth packaging bag 4 onto the discharge pipe.

[0019] The cam connecting rod 20 is connected to the first push rod 21 and the second push rod 22 at the same time. The first push rod 21 is hinged to the first push rod linkage shaft 29, and the first push rod linkage shaft 29 is connected to the rotating shaft 36. The output end of the rotating shaft 36 is connected to the buffer cylinder swing arm 25. The two ends of the buffer cylinder are respectively hinged to the buffer cylinder swing arm 25 and the swing arm 24. The second push rod 22 is connected to the second push rod linkage shaft 30. The movable horizontal guide bent plate 11 and the bag squeezing rubber wheel 12 installed on the bag squeezing rubber wheel fixing plate 14 are connected to the second push rod linkage shaft 30 through the L-shaped connecting plate 16.

[0020] Initially, the electric motor 8 drives the cam device 7 to rotate, the cam connecting rod 20 drives the second push rod 22, and the second push rod 22 drives the second push rod linkage shaft 30 to rotate, and the L-shaped connecting plate 16 connecting the movable horizontal guide bent plate 11 and the bag squeezing rubber wheel-fixing plate 14 and the bag squeezing rubber wheel-12 moves in the direction away from the long horizontal guide bent plate 9. At the same time, the cam connecting rod 20 drives the first push rod 21 to move, and the first push rod 21 drives the buffer cylinder swing arm 25 to rotate downward through the first push rod linkage shaft 29 and the rotating shaft 36, so that the suction cup fixing rod 19 rotates downward through the swing arm 24 hinged to the buffer cylinder swing arm 25. When the cam device 7 reaches the cam device rotation low position 33, the negative pressure suction cup 18 sucks the valve port packaging bag 4.

[0021] The cam device 7 continues to rotate to reach the cam device rotation high position 32, and the L-shaped connecting plate 16 connecting the movable horizontal guide bent plate 11 and the bag squeezing rubber wheel-fixed plate 14 and the bag squeezing rubber wheel-12 returns to the initial position, and the sucked valve port packaging bag 4 is squeezed tightly onto the bag shooting belt 27 by the bag squeezing rubber wheel-12, and at the same time, the opened valve port is maintained in the cavity formed by the movable horizontal guide bent plate 11 and the long horizontal guide bent plate 9.

[0022] The cam device 7 on the top of the frame 1 drives the bag taking mechanism 5 to complete the suction of the valve port packaging bag 4 within one rotation cycle.

[0023] The bag taking device 5 is provided with a buffer cylinder 23, which can reduce the inertial impact generated when the swing arm 24 moves. The buffer cylinder 23 has built-in pressure and does not need an external pressure source.

[0024] The swing arm 24 in the bag taking device 5 and the parallel rod 28 above the swing arm are respectively hinged to the suction cup fixing rod 19, and the formed parallelogram structure can make the negative pressure suction cup 18 installed on the suction cup fixing rod 19 always perpendicular to the valve mouth packaging bag 4 to be sucked.

[0025] The cavity formed by the long horizontal guide curved plate 9 and the short horizontal guide curved plate 10 in the horizontal guide device 35 keeps the valve port of the packaging bag opened until the bag shooting device shoots the valve port packaging bag 4 onto the discharge pipe and is connected to the connecting vertical plate 2 through the suspension bracket 3.

[0026] The bag shooting electric motor 17 in the bag shooting device 6 is connected to the connecting vertical plate 2 through the motor bracket 31, the bag squeezing rubber wheel 2 13 installed on the bag squeezing rubber wheel 2 fixing plate 15 is connected to the connecting vertical plate 2 through the suspension bracket 3, one end of the active belt 26 is installed on the bag shooting electric motor 17, and the other end is installed on the lower part of the active pulley 34, one end of the bag shooting belt 27 is installed on the upper part of the active pulley 34, and the other end is connected to the passive pulley 36.
