Description

Technical Field

[0001] This utility model relates to the field of valve-mouth packaging technology for powder materials, specifically a valve-mouth packaging bag injection mechanism. Background Technology

[0002] Currently, most powder materials are packaged using valve-sealed bags, which involves manual bag insertion, resulting in poor working conditions, high labor intensity, and low levels of modern factory automation. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a valve-mouth packaging bag injection mechanism that features automated control and high efficiency.

[0004] The technical solution of this utility model is: a valve-mouth packaging bag ejection mechanism, including a bag-taking device, a horizontal guide device, and an ejection device. The action of the bag-taking device is driven by a cam device, and the rotation of the cam device is driven by an electric motor. It can periodically pick up valve bags. The bag-taking device and the horizontal guide device work together. The valve of the valve-mouth packaging bag picked up by the bag-taking device is opened, and the valve of the packaging bag is kept open in the horizontal guide device until the ejection device ejects the valve-mouth packaging bag onto the discharge pipe.

[0005] Preferably, the cam device at the top of the frame drives the bag-picking device to complete the suction of the valve-mouth packaging bag within one rotation cycle.

[0006] Preferably, the cam device connects the first push rod and the second push rod via a connecting rod. The first push rod is hinged to the first push rod linkage shaft, which is connected to the rotating shaft. The output end of the rotating shaft is connected to the buffer cylinder swing arm, and both ends of the buffer cylinder are hinged to the buffer cylinder swing arm and the swing arm, respectively. The second push rod is connected to the output end of the second push rod linkage shaft. The movable horizontal guide plate and the extrusion roller mounted on the fixed plate of the extrusion roller are connected to the second push rod connecting shaft via an L-shaped connecting plate.

[0007] Preferably, the movable horizontal guide plate and the extrusion roller installed on the fixed plate of the extrusion roller are connected to the second push rod connecting shaft through an L-shaped connecting plate. After the bag is taken out, the extrusion roller squeezes the valve opening of the packaging bag tightly with the bag injection belt. At the same time, the cavity formed by the movable horizontal guide plate and the long horizontal guide plate keeps the packaging bag valve opening open.

[0008] Preferably, the bag-retrieving device is equipped with a buffer cylinder, which can reduce the inertial impact generated during the swing arm movement, and the buffer cylinder has built-in pressure, so no external pressure source is required.

[0009] Preferably, the swing arm and the parallel rod above the swing arm in the bag-retrieving device are respectively hinged to the suction cup fixing rod, and the resulting parallelogram structure ensures that the negative pressure suction cup installed on the suction cup fixing rod is always perpendicular to the valve opening packaging bag to be retrieved.

[0010] Preferably, the cavity formed by the long horizontal guide plate and the short horizontal guide plate in the horizontal guide device keeps the packaging bag valve open until the bag injection device injects the packaging bag from the valve onto the discharge pipe, and is connected to the connecting upright plate through the suspension bracket.

[0011] Preferably, the bag-shooting electric motor in the bag-shooting device is connected to the connecting plate via a motor bracket, and the second bag-shooting rubber wheel, which is mounted on the fixing plate of the second bag-shooting rubber wheel, is connected to the connecting plate via a suspension bracket. One end of the driving belt is installed on the bag-shooting electric motor, and the other end is installed on the lower part of the driving belt pulley. One end of the bag-shooting belt is installed on the upper part of the rotating belt pulley, and the other end is connected to the passive belt pulley. Attached Figure Description

[0018] like Figures 1 to 5 As shown, this embodiment provides a valve-mouth packaging bag injection mechanism, including a bag-taking device 5, a horizontal guide device 35, and an injection device 6. The action of the bag-taking device 5 is driven by a cam device 7, and the electric motor 8 drives the rotation of the cam device 7, which can periodically pick up the valve-mouth bag 4. The bag-taking device 5 and the horizontal guide device 35 work together. The valve-mouth packaging bag 4 picked up by the bag-taking device 5 has its valve opening open, and it is kept in the horizontal guide device 35 in the open state until the injection device 6 injects the valve-mouth packaging bag 4 onto the discharge pipe.

[0019] Cam connecting rod 20 connects first push rod 21 and second push rod 22. First push rod 21 is hinged to first push rod linkage shaft 29. First push rod linkage shaft 29 is connected to rotating shaft 36. Output end of transmission shaft 36 is connected to buffer cylinder swing arm 25. Both ends of buffer cylinder 23 are hinged to buffer cylinder swing arm 25 and swing arm 24 respectively. Second push rod 22 is connected to second push rod linkage shaft 30. Movable horizontal guide plate 11 and extrusion rubber wheel 12 installed on extrusion rubber wheel fixed plate 14 are connected to second push rod linkage shaft 30 through 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, which in turn drives the second push rod linkage shaft 30 to rotate. The L-shaped connecting plate 16, which connects the movable horizontal guide plate 11 and the bag squeezing wheel fixing plate 14, moves away from the long horizontal guide plate 9. At the same time, the cam connecting rod 20 drives the first push rod 21 to move. 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. This causes the suction cup fixing rod 19 to rotate downward through the swing arm 24, which is hinged to the buffer cylinder swing arm 25. When the cam device 7 reaches the low position 33 of the cam device rotation, the negative pressure suction cup 18 picks up the valve opening packaging bag 4.

[0021] As the cam device 7 continues to rotate to the high position 32, the L-shaped connecting plate 16, which connects the movable horizontal guide plate 11 and the bag squeezing wheel-fixed plate 14, returns to the initial position. The sucked-in valve-mouth packaging bag 4 is squeezed tightly onto the bag injection belt 27 by the bag squeezing wheel-12, while the opened valve mouth is held in the cavity formed by the movable horizontal guide plate 11 and the long horizontal guide plate 9.

[0022] The cam device 7 at the top of the frame 1 drives the bag-picking device 5 to pick up the valve-mouth packaging bag 4 within one rotation cycle.

[0023] The bag-taking device 5 is equipped 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 require an external pressure source.

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

[0025] The cavity formed by the long horizontal guide plate 9 and the short horizontal guide plate 10 in the horizontal guide device 35 keeps the packaging bag valve open until the bag injection device injects the packaging bag 4 from the valve onto the discharge pipe, and connects it to the connecting upright 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 plate 2 via the motor bracket 31. The second bag-shooting rubber wheel 13, which is installed on the fixing plate 15 of the second bag-shooting rubber wheel, is connected to the connecting plate 2 via the suspension bracket 3. One end of the driving belt 26 is installed on the bag-shooting electric motor 17, and the other end is installed on the lower part of the driving belt pulley 34. One end of the bag-shooting belt 27 is installed on the upper part of the driving belt pulley 34, and the other end is connected to the passive belt pulley 36.
