Description

Technical Field

[0001] The utility model relates to a packaging bag pushing mechanism. Background Art

[0002] The secondary bagging machine is used for secondary packaging of materials with regular shapes after primary filling and vacuuming. Secondary packaging can effectively reduce the probability of damage caused by vacuum packaging during logistics and transportation to ensure the hygiene and quality of food. The traditional delivery and pushing bag process is complicated, and the pushing bag guidance is insufficient. After the bag is pushed into the bag, it is retracted immediately, which will cause the material bag to be pressed when it is transported to the heat sealing station, which will cause the heat sealing packaging to fail. Improvement is needed urgently. Utility Model Content

[0005] Furthermore, a square boost opening is provided on the upper surface of the bag pushing channel support plate at the pushing end of the bag pushing assembly, and a boost plate is arranged in the square boost opening. The end of the boost plate is driven by a boost cylinder to slide longitudinally to drag the material bag and the packaging bag to the next workstation.

[0006] Furthermore, the driving member is composed of a synchronous belt, a bag pushing motor and two pulleys, and the longitudinal pushing plate is fixedly connected to the synchronous belt and driven by the bag pushing motor to move longitudinally.

[0007] Furthermore, a bag pushing rubber block which is beneficial to pushing the bag is fixedly arranged at the end of the horizontal section of the bag pushing plate.

[0008] Furthermore, the bag supporting assembly includes a bag supporting plate extending into the packaging bag and supported on both lateral sides of the bag opening, and the top and side of the bag supporting plate close to the bag lifting assembly are fixedly connected with a bag pushing guide plate for easy guidance, and the bag pushing guide plates are all unfolded outward to be open.

[0009] Furthermore, the bag lifting assembly includes a bag lifting plate, and bag lifting cylinders for driving the bag lifting plate to rise and fall are arranged at the lower ends of both lateral sides of the bag lifting plate.

[0010] Furthermore, a detection switch for sensing whether a bag is being supported below is provided on the longitudinal frame located directly above the bag supporting assembly.

[0019] In an embodiment of the utility model, a square boosting opening E13 is provided on the upper surface of the bag pushing channel support plate at the pushing end of the bag pushing assembly, and a boosting plate E14 is arranged in the square boosting opening. The end of the boosting plate is driven by a boosting cylinder E15 to slide longitudinally to drag the material bag and the packaging bag to the next workstation, and the boosting cylinder is fixedly connected to the lower end surface of the boosting plate.

[0020] In the embodiment of the utility model, the driving member is composed of a synchronous belt E16, a bag pushing motor E17 and two pulleys E18. The longitudinal push plate is fixedly connected to the synchronous belt and is driven by the synchronous belt to move longitudinally through the bag pushing motor.

[0021] In the embodiment of the utility model, a bag pushing rubber block E19 which is beneficial to pushing the bag is fixedly provided at the end of the horizontal section of the bag pushing plate.

[0022] In an embodiment of the utility model, the bag supporting assembly includes a bag supporting plate E20 extending into the packaging bag and supported on both lateral sides of the bag opening. The top and side of the bag supporting plate close to the bag lifting assembly are fixedly connected with a bag pushing guide plate E21 for easy guidance. The bag pushing guide plates are all unfolded outward to be open.

[0023] In the embodiment of the utility model, the bag lifting assembly includes a bag lifting plate E22, and bag lifting cylinders E23 for driving the bag lifting plate to rise and fall are arranged at the lower ends of both lateral sides of the bag lifting plate.
