[0025] Reference Figures 1 to 4 , several embodiments of a fully automatic bag-feeding packaging machine of the utility model are given below.

[0026] A fully automatic bag-feeding packaging machine comprises a frame 1, a circular station turntable 2 rotatably connected to the frame 1, and a plurality of cylinder grippers 3 arranged around the circular station turntable 2. A bag feeding mechanism 4, a bag opening mechanism 5, a feeding mechanism 6 and a bag sealing mechanism 7 are arranged circumferentially on the outer circumference of the circular station turntable 2. The bag feeding mechanism 4 is arranged perpendicular to the circular station turntable 2, and one end of the bag feeding mechanism 4 is cooperatively connected to the cylinder gripper 3. A coding mechanism 8 is arranged between the bag opening mechanism 5 and the feeding mechanism 6; the feeding mechanism 6 is relatively arranged directly above the cylinder gripper 3; a discharging conveyor belt 9 is arranged below the bag sealing mechanism 7; the circular station turntable 2 and the above-mentioned mechanisms are independently driven and pushed by their own motors and cylinders without a transmission connection relationship.

[0027] Specifically, the movement of the circular workstation turntable 2 is independently driven by a turntable motor installed at the bottom of the frame 1. The circular workstation turntable 2 is connected to the output shaft end of the driving motor and is arranged to rotate in a circle under the action of the driving motor; the cylinder gripper 3 is composed of two upper and lower clamping plates, and one end is linked to the cylinder. Under the action of the cylinder, the upper and lower clamping plates are closed to clamp the bag to complete the bag taking action. The finger surfaces of the upper and lower clamping plates are designed to be flat and long planes to match the bag-shaped characteristics of the prefabricated bags. At the same time, in order to ensure reliable bag clamping, a 2-3mm thick rubber sheet is attached to the finger surface of the clamping plate.

[0028] In this embodiment, the bag feeding mechanism 4 includes a feeding conveyor belt 41, a bag taking push rod 42 and a driving cylinder 43. The bag taking push rod 42 is installed on the feeding conveyor belt 41, and the bag taking push rod 42 is linked to the driving cylinder 43.

[0029] In this embodiment, the bag opening mechanism 5 includes a mounting support 51, a connecting rocker arm 52, and left and right bag opening nozzles 53. The connecting rocker arm 52 is movably connected to the mounting support 51, and the left and right bag opening nozzles 53 are located on the inner side of the connecting rocker arm 52 and fixedly connected. The left and right bag opening nozzles 53 make a linear movement towards or away from each other under the drive of the connecting rocker arm 52.

[0030] Specifically, after the packaging bags are neatly arranged, they are placed on the feeding conveyor 41. The driving cylinder 43 drives the bag taking push rod 42 to swing back and forth, and a single packaging bag is sucked, grasped, and transferred to the cylinder gripper 3. When the packaging bag is grabbed by the cylinder gripper 3 through the bag feeding mechanism 4 and reaches the bag taking position under the rotation of the circular station turntable 2, the cylinder action used to drive the bag opening mechanism 5 is controlled by the PLC system of the control mechanism 11, and the connecting swing rod 52 is driven to move apart from each other, so that the left and right bag opening suction nozzles 53 open and open the bag, completing the bag opening action. At the same time, in order to ensure reliable bag clamping, the left and right bag opening suction nozzles 53 use vacuum suction cups to quickly clamp the packaging bag. The bag taking and clamping action is a simple opening and closing action. The left and right bag opening suction nozzles 53 are symmetrical structures, so the power source of the bag opening mechanism 5 is designed as a pneumatic component. The opening and closing action of the left and right bag opening suction nozzles 53 is realized by the reciprocating motion of the push rod of the small cylinder and combined with the connecting swing rod 52 to realize the bag clamping and bag placing operations.

[0031] In this embodiment, the feeding mechanism 6 includes an annular conveyor belt 61, a feeding barrel 62 and a lower hopper 63. The feeding barrels 62 are arranged equidistantly on the annular conveyor belt 61, and one of the feeding barrels 62 close to one end of the circular workstation turntable 2 is sleeved with the lower hopper 63, and the lower feeding port of the lower hopper 63 is arranged opposite to the bag opening of the packaging bag.

[0032] Specifically, a plurality of feeding barrels 62 are provided, and the feeding barrels 62 are closely arranged on the circular conveyor belt. The bottom of the circular conveyor belt 61 is connected to a machine base for support. The entire discharge operation is controlled by the PLC system of the control mechanism 11. The same weight of materials is stored in each feeding barrel 62. When the circular conveyor belt 61 drives the feeding barrel 62 to rotate to the lower hopper 63, the material is released by the feeding barrel 62 and enters the packaging bag through the lower hopper 63. After the discharge is completed, the hopper rises to ensure the normal operation of the circular station turntable 2 and the cylinder gripper 3 to avoid interference therewith.

[0033] In this embodiment, a shaping mechanism 10 is arranged between the feeding mechanism 6 and the bag sealing mechanism 7, and the shaping mechanism 10 includes left and right bag-supporting plates 101, a bag-supporting cylinder 102 (not shown in the figure) and a bag-supporting bracket 103; the left and right bag-supporting plates 101 and the bag-supporting cylinder 102 (not shown in the figure) are fixedly connected to the bag-supporting bracket 103, and the left and right bag-supporting plates 101 swing towards or away from each other under the drive of the bag-supporting cylinder 102 (not shown in the figure).

[0034] Specifically, the left and right bag-supporting plates 101 on the shaping mechanism 10 keep the material stably open under the action of the bag-supporting cylinder 102 (not shown in the figure), and at the same time shape and arrange the packaging bag to facilitate the sealing of the packaging bag, thereby facilitating subsequent processing.

[0035] In this embodiment, the bag sealing mechanism 7 includes a heat sealing mounting base 71, left and right heat sealing heads 72 and a heat sealing cylinder 73. The heat sealing cylinder 73 (not shown in the figure) is fixedly mounted on one side of the heat sealing mounting base 71, and the heat sealing cylinder 73 (not shown in the figure) is transmission-connected to the left and right heat sealing heads 72 so that the left and right heat sealing heads 72 can swing towards or away from each other.

[0036] Specifically, the operation of the bag sealing mechanism 7 is controlled by the PLC system of the control mechanism 11. The heat sealing cylinder 73 (not shown in the figure) is used as a power source to drive the left and right heat sealing heads 72 to move. At the same time, the left and right heat sealing heads 72 are slidably connected with the heat sealing mounting base 71 through gear racks, so that the left and right heat sealing heads 72 move toward each other for heat sealing. The left and right heat sealing heads 72 use polyethylene sealing plates, and there are heating pipes on the plates to provide heat sources to the plates, so that the temperature is controlled within a certain range to ensure the heat sealing effect.

[0037] In this embodiment, a control mechanism 11 is further provided on the frame 1. The control mechanism 11 is located on one side of the bag feeding mechanism 4, and the control mechanism 11 is electrically connected to each of the above mechanisms to control the packaging machine to automatically complete the bag opening and packaging action.

[0038] Specifically, the control mechanism 11 controls the movement of the circular station turntable 2, and controls the movement of the bag feeding mechanism 4, the bag opening mechanism 5, the feeding mechanism 6, the shaping mechanism 10 and the heat sealing mechanism respectively. Through the control of the control mechanism 11, various motion control effects can be achieved; the control mechanism 11 includes a controller such as a PLC (programmable logic controller) (not shown), and an input device connected to the PLC, such as a touch screen; the PLC can be electrically connected to the motors and cylinders of the above-mentioned components in a common manner (such as a bus), so as to achieve a good electrical connection effect and achieve the effect of coordinated work of various mechanisms, thereby improving work efficiency.

[0039] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
