[0020] like Figure 1-2 As shown, an automatic bagging and packaging device includes a film conveying mechanism, a quantitative weighing mechanism, a film bag gripping and transferring mechanism, a bag sealing mechanism, and a feeding conveyor belt 1.

[0021] The film conveying mechanism includes an unwinding roller 2, several guide rollers 3 and a power roller group arranged in sequence. The power roller group includes a drive roller 4 and a driven roller 5. The drive roller 4 is driven to rotate by a motor. A film bag 6 connected end to end is wound on the unwinding roller 2. After being guided by the guide rollers 3, the film bag 6 passes between the drive roller 4 and the driven roller 5 in a downward state. A cutting tool 7 is provided at the bottom of the power roller group.

[0022] The film bag gripping and transfer mechanism includes a lateral movement mechanism, a clamping mechanism, and a suction cup mechanism. The lateral movement mechanism includes a lateral slide rail 8 and a lateral mounting plate 9 mounted on the lateral slide rail 8. The lateral mounting plate 9 is driven by a first drive mechanism to move on the lateral slide rail 8. The clamping mechanism includes a left gripper 10 and a right gripper 11 located at opposite ends of the lateral mounting plate 9. The right gripper 11 is fixedly connected to the lateral mounting plate 9. A small slide rail 12 is fixedly mounted on the lateral mounting plate 9, perpendicular to the lateral slide rail 8. A small slider 13 is mounted on the small slide rail 12, and a tension spring 14 is fixedly connected to the small slider 13. The tension spring 14 is fixedly connected to the lateral mounting plate 9. The left gripper 10 is fixedly mounted on the small slider 13. The suction cup... The mechanism includes a front clamping plate 15 and a rear clamping plate 16. A front slide rail 17 and a rear slide rail 18 are installed in the middle of the transverse sliding mounting plate 9. The front slide rail 17 and the rear slide rail 18 are parallel to the transverse sliding rail 8. A front slider 19 is installed on the front slide rail 17 and moves on the front slide rail 17 by a third drive mechanism. A rear slider 20 is installed on the rear slide rail 18 and moves on the rear slide rail 18 by a fourth drive mechanism. The front clamping plate 15 is fixedly connected to the front slider 19 and the rear clamping plate 16 is fixedly connected to the rear slider 20. Several vacuum suction cups 21 are installed on the inner side of the front clamping plate 15 and the inner side of the rear clamping plate 16, respectively. One end of the transverse sliding rail 8 is located below the power roller group and the other end is located above the feeding conveyor belt 1.

[0023] The quantitative weighing mechanism includes a weighing hopper 22 with a weighing function, and a discharge pipe 23 with a valve is provided at the lower end of the weighing hopper 22. The weighing hopper 22 has a weighing function, and each time it releases a set amount of material, which is fed into the membrane bag 6 through the material port 33 opened in the middle of the transverse mounting plate 9. The lower end of the discharge pipe 23 can be connected to a retractable corrugated pipe, and is driven to lift and lower by a drive mechanism such as a cylinder, so that the corrugated pipe can be directly inserted into the membrane bag 6 through the material port 33 to feed the material.

[0024] The film bags 6, connected end to end, are unwound from the unwinding roller 2 by the traction of the power roller group. The left gripper 10 and right gripper 11 activate, grasping both sides of the last film bag 6 and cutting it off using the cutting tool 7. Then, the transverse mounting plate 9 moves on the transverse slide rail 8 to directly below the weighing hopper 22. The front gripper 15 and rear gripper 16 clamp the bag opening, and the vacuum suction cup 21 creates a vacuum suction effect on both sides of the film bag 6. Then, the front gripper 15 and rear gripper 16 move in opposite directions, opening the bag opening. During this process, the left gripper 10 is pulled, causing the bag opening to widen. The feed pipe 23 is aligned with the bag opening, loading the film bag 6 with a set amount of material. The vacuum suction cup 21 returns to normal pressure, releasing the film bag 6. The front gripper 15 and rear gripper 16 reset, the left gripper 10 resets, and the bag opening shrinks. The transverse mounting plate 9 moves on the transverse slide rail 8, causing the film bag 6 to move onto the unloading conveyor belt 1. The left gripper 10 and the right gripper 11 release the film bag 6, and the unloading conveyor belt 1 transfers the packaged product.

[0025] Furthermore, a bag opening heat-sealing mechanism is installed on the transverse mounting plate 9. This mechanism includes a front heating plate 24 and a rear heating plate 25. The front heating plate 24 is mounted on the front outer slider 26, which is mounted on the front slide rail 17 and driven to move along the front slide rail 17 by a fifth drive mechanism. The rear heating plate 25 is mounted on the rear outer slider 27, which is mounted on the rear slide rail 18 and driven to move along the rear slide rail 18 by a sixth drive mechanism. The front heating plate 24 and the rear heating plate 25 are staggered in height from the front clamping plate 15 and the rear clamping plate 16, and are connected to the front outer slider 26 or the rear outer slider 27 respectively using L-shaped connecting plates. The front heating plate 24 and the rear heating plate 25 are energized and heated to heat-seal the bag opening.

[0026] Furthermore, a vacuum tube 28 is installed on the transverse mounting plate 9. The vacuum tube 28 is driven to rise and fall by a lifting drive mechanism and is connected to a vacuuming device. After the membrane bag 6 is filled with material falling from the weighing hopper 22, the vacuum tube 28 is driven to descend and insert into the membrane bag 6 by the lifting drive mechanism. The front clamping plate 15 and the rear clamping plate 16 move closer together, making the bag opening smaller. The vacuum tube 28 evacuates the membrane bag 6. After the vacuuming is almost finished, the front heating plate 24 and the rear heating plate 25 in the bag opening heat sealing mechanism gradually move closer together, the vacuum tube 28 rises, and the front heating plate 24 and the rear heating plate 25 clamp the bag opening and heat it for heat sealing. To improve the shaping effect, a lifting support plate 31 can be set below the weighing hopper 22. The lifting support plate 31 is driven to move up and down by a cylinder. Once the membrane bag 6 is full of material, the lifting pallet 31 moves up and down repeatedly, tapping the lower end of the membrane bag 6 to make the material distribution in the membrane bag 6 more even, while accelerating air expulsion and promoting a faster vacuuming process. A cylinder can be used as the lifting drive mechanism.

[0027] Furthermore, the cutting tool 7 is driven to move by the seventh drive mechanism, and the direction of movement of the cutting tool 7 is parallel to the axis of the drive roller 4. After the left gripper 10 and the right gripper 11 grasp the two sides of the film bag 6 respectively, the cutting tool 7 moves to separate the grasped film bag 6 from the other film bags 6 and form a bag opening at the cut.

[0028] Furthermore, an automatic palletizing robot is provided at the end of the unloading conveyor belt 1. The automatic palletizing robot removes the film bag 6 from the end of the unloading conveyor belt 1 and transfers it to the palletizing area for palletizing.

[0029] Furthermore, a laser marking device 29 is provided on one side of the feeding conveyor belt 1. The laser marking device 29 marks the packaging bags containing the products.

[0030] Furthermore, the first drive mechanism is a cylinder, the third drive mechanism is a cylinder, the fourth drive mechanism is a cylinder, the fifth drive mechanism is a cylinder, the sixth drive mechanism is a cylinder, and the lifting drive mechanism is a cylinder. The cylinder drives the corresponding components to perform linear movement; alternatively, a drive mechanism capable of performing linear movement, such as an electric push rod, can be used.

[0031] Furthermore, a liquid addition pipe 30 is installed on one side of the feeding pipe 23, and the liquid addition pipe 30 is connected to a liquid storage tank via a metering pump. During the process of feeding material into the bag through the feeding pipe 23, other additives and other small materials can be added to the bag through the liquid addition pipe 30.

[0032] It is worth mentioning that the technical features of cylinders, motors, electric push rods, metering pumps, laser marking equipment, automatic palletizing robots, etc. involved in this patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field and should not be regarded as the inventive point of this patent. This patent will not be further elaborated in detail.

[0033] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
