Abstract
Description
A fully automatic bag-feeding packaging machine Technical Field
[0001] This utility model relates to the field of packaging equipment technology, and in particular to a fully automatic bag-feeding packaging machine. Background Technology
[0002] With the continuous improvement of industrial automation, the packaging industry has an increasing demand for efficient, precise, and stable packaging equipment. Fully automatic bag-feeding packaging machines, as an important type of packaging equipment, are widely used in the packaging of various materials because they can automatically complete processes such as bag picking, bag opening, metering, filling, and sealing.
[0003] However, existing fully automatic bag-packing machines still have certain shortcomings. For example, they simply open the packaging bag using suction cups, which are typically only used to pick up and lift the bag. Since the suction force relies on vacuum pressure or mechanical structure, its strength may be unstable due to environmental factors or different bag materials, potentially leading to weak adhesion, bag detachment, and ultimately affecting the continuity and stability of the packaging. Secondly, the suction cup height of traditional equipment is usually fixed and cannot be adjusted for different bag sizes. This makes it difficult for the suction cup to accurately adhere to the optimal position when dealing with bags of varying heights. A search revealed that the technical solution provided by utility model application number CN202120588610.3 also suffers from the aforementioned problems. Summary of the Invention
[0004] The purpose of this invention is to provide a fully automatic bag-feeding packaging machine that allows the suction cup and pressure plate to work together to form a dual protection mechanism. The suction cup is responsible for adsorbing the packaging bag, while the pressure plate provides auxiliary support, thereby ensuring that the packaging bag will not fall off due to insufficient suction during the opening process. The overall height of the suction cup can be adjusted within a certain range, so that the packaging machine can be used for packaging bags of various sizes, thus avoiding the need for frequent equipment replacement or complex adjustments.

The second base 9 has a third conveyor roller 10 rotatably connected to its inner surface, a second conveyor belt 11 driven by the outer surface of the third conveyor roller 10, and a fourth conveyor roller 12 rotatably connected to its inner surface. The first conveyor belt 4 has a first gear 13 fixedly connected to its outer surface, and the third conveyor roller 10 has a second gear 14 fixedly connected to its outer surface, ensuring that the first conveyor belt 4 and the second conveyor belt 11 are driven in opposite directions. The outer surface of the first conveyor roller 3 is rotatably connected to the first base 1, the outer surface of the second conveyor roller 5 is driven by the first conveyor belt 4, and the outer surface of the fourth conveyor roller 12 is driven by the second conveyor belt 11, facilitating the operation of the first conveyor belt 4 and the second conveyor belt 11. The inner surface of the second base 9 is in contact with the second cylinder 15 to avoid affecting the movement of the second base 9. The first gear 13 and the second gear 14 mesh to ensure that the first conveyor belt 4 and the second conveyor belt 11 are driven in opposite directions. There are four U-shaped frames 16, which are linearly distributed from left to right. The first motor 2 and the electric push rod 17 are both electrically connected to an external power source.
[0029] A guide rail frame 20 is fixedly connected to the upper end of the U-shaped frame 16. A second motor 21 is fixedly connected to the upper end of the guide rail frame 20. A lead screw 22 is fixedly connected to the output end of the second motor 21. A slider 23 is threadedly connected to the outer surface of the lead screw 22. A third cylinder 24 is fixedly connected to the outer surface of the slider 23. A pressure plate 25 is fixedly connected to the output end of the third cylinder 24. A limit groove 27 is provided on the outer surface of the guide rail frame 20. The inner surface of the limit groove 27 is adapted to the slider 23 to limit the movement of the slider 23. The outer surface of the lead screw 22 is rotatably connected to the guide rail frame 20. The second motor 21 is electrically connected to an external power source.
[0030] Working Principle: During operation, firstly, based on the size and height of the packaging bag, the second cylinder 15 is activated, driving the U-shaped frame 16 to move the suction cup 18 upwards. This allows the suction cup 18 to move to the opening position corresponding to the size of the packaging bag, accommodating packaging operations for various sizes of bags. Subsequently, the existing bag feeding technology transports the packaging bag to one side of the first conveyor belt 4 and the second conveyor belt 11. The second cylinder 15 is then activated, driving the second fixed plate 8 to move the second conveyor belt 11 above the second base 9 towards the first conveyor belt 4 with the cooperation of the rollers 26. Then, the first motor 2 is activated, driving the first conveyor roller 3 to rotate the first conveyor belt 4. Simultaneously, under the meshing action of the first gear 13 and the second gear 14, the first conveyor belt 4, the third conveyor roller 10, and the fourth conveyor roller 12 drive the second conveyor belt 11 to rotate in the opposite direction to the first conveyor belt 4. When the distance between the first conveyor belt 4 and the second conveyor belt 11 is sufficiently small... The packaging bag is placed between the first conveyor belt 4 and the second conveyor belt 11. At this time, the packaging bag will be conveyed between the first conveyor belt 4 and the second conveyor belt 11. When the opening of the packaging bag moves to the position of the suction cup 18, the first motor 2 is turned off and the electric push rod 17 is started to drive the suction cup 18 to adhere to both sides of the opening of the packaging bag. Then, the third cylinder 24 is started to drive the pressure plate 25 to extend outward. Then, the second motor 21 is started to drive the lead screw 22 to move the pressure plate 25 downward into the inside of the packaging bag under the action of the slider 23. Finally, the electric push rod 17 and the pressure plate 25 are retracted in sequence. With the assistance of the pressure plate 25, the two sides of the packaging bag can be opened to prevent the packaging bag from falling off due to insufficient suction of the suction cup 18. At the same time, the second cylinder 15 is retracted and the packaging bag is filled by the external filling equipment. After the filling is completed, the second cylinder 15 is restarted so that the filled packaging bag can continue to be transported to the subsequent sealing equipment.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
