[0001] This utility model belongs to the field of packaging machine technology, and more specifically, it relates to a microcomputer-controlled automatic packaging machine for weighing and sewing. Background Technology

[0002] The weighing and sewing automatic packaging machine is an automated packaging equipment widely used in the food, chemical, and agricultural product industries. It is used for the automatic weighing, bagging, and sewing of bulk materials, and is generally suitable for packaging granular, powdered, or pellet materials, achieving an efficient and precise packaging process.

[0003] Based on the above, the inventors have discovered the following problems: Most current automatic weighing and sewing packaging machines typically transport the packaging bags to the bottom of the sewing machine via a conveyor belt after weighing. However, the packaging bags are not protected during transportation, and they are prone to tilting and falling over during movement, causing material spillage and losses. At the same time, it is not convenient to adjust the height of the sewing machine, making it inconvenient to sew the edges of packaging bags of different heights.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a microcomputer-controlled weighing and sewing automatic packaging machine in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effectiveness of this microcomputer-controlled automatic weighing and sewing packaging machine are achieved through the following specific technical means:

[0012] Furthermore, a controller is mounted on one side of the mounting bracket.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By using electric cylinders, limit plates, and guide wheels in combination, a set of electric cylinders is activated to adjust the position of a set of limit plates. In turn, the set of limit plates can limit packaging bags of different sizes to the top of the conveyor belt, preventing the packaging bags from shifting and tipping over, thus avoiding the problem of material spillage. At the same time, the guide wheels can make the movement of packaging bags smoother and improve the transportation efficiency.

[0028] The limiting component includes an electric cylinder 8 installed on one side of the fixed plate 7. The output end of the electric cylinder 8 is connected to a limiting plate 9. A mounting groove 13 is provided on one side of the limiting plate 9. Several guide wheels 14 are installed inside the mounting groove 13 via a rotating shaft. By cooperating with the electric cylinder 8, the limiting plate 9 and the guide wheels 14, a set of electric cylinders 8 is activated to adjust the position of a set of limiting plates 9. Thus, a set of limiting plates 9 can limit packaging bags of different sizes to the top of the conveyor belt 2, preventing the packaging bags from shifting and tipping over, avoiding the problem of material spillage. At the same time, the guide wheels 14 can make the movement of the packaging bags smoother and improve the transportation efficiency.

[0029] The adjustment assembly includes a motor 15 mounted on the top of the support frame 10. The output end of the motor 15 passes through the support frame 10 and is connected to a threaded rod 16. A connecting plate 17 is threaded onto the threaded rod 16. One side of the connecting plate 17 is connected to a sewing machine 11. By cooperating with the motor 15, the threaded rod 16, the connecting plate 17, and the sewing machine 11, the motor 15 is started, which drives the threaded rod 16 to rotate. Under the limiting action of the guide rod 18, the threaded rod 16 drives the connecting plate 17 to move. This allows the position of the sewing machine 11 to be adjusted according to the height of the packaging bag, facilitating the sewing of packaging bags of different heights and improving the adaptability of the device.

[0030] The support frame 10 has a set of guide rods 18 installed at the top inner side, and the guide rods 18 pass through the connecting plate 17 and are connected to the bottom inner side of the support frame 10.

[0031] The storage tank 4 has a partition 19 installed inside, and a discharge pipe 20 is installed at the bottom of the partition 19. A solenoid valve 21 is installed on the discharge pipe 20.

[0032] The weighing chamber 6 is equipped with a discharge pipe 22 at its bottom, and a solenoid valve 23 is installed on the discharge pipe 22. A pressure sensor 24 is installed at the bottom of the storage tank 4 and is connected to the bottom of the weighing chamber 6.

[0033] The mounting bracket 1 has a controller 12 installed on one side.

[0034] The specific usage and function of this embodiment are as follows:

[0035] First, check the integrity of the device. Only after confirming it is correct can it be used. Material is added to the storage bin 4 through the feed pipe 5, accumulating on top of the partition 19. The packaging bag is placed at the bottom of the discharge pipe 22. Then, the controller 12 opens the solenoid valve 21, allowing the material to enter the weighing chamber 6 through the discharge pipe 20. The pressure sensor 24 measures the weight of the material inside the weighing chamber 6. When the weight reaches a predetermined value, the controller 12 automatically closes the solenoid valve 21 and opens the solenoid valve 23, allowing the material to enter the packaging bag through the discharge pipe 22. The conveyor belt 2 then transports the packaging bag. A set of electric cylinders 8 is activated to position a set of limit plates 9. The adjustment process allows a set of limiting plates 9 to keep packaging bags of different sizes at the top of the conveyor belt 2, preventing them from shifting or tipping over and avoiding material spillage. At the same time, the guide wheels 14 make the movement of the packaging bags smoother, improving the transportation efficiency. After being transported to the bottom of the sewing machine 11, the sewing machine 11 sews the edges of the packaging bags. When the height of the sewing machine 11 needs to be adjusted, the motor 15 is started. The motor 15 drives the threaded rod 16 to rotate. Under the limiting action of the guide rod 18, the threaded rod 16 drives the connecting plate 17 to move, thereby adjusting the position of the sewing machine 11 according to the height of the packaging bags. This facilitates sewing packaging bags of different heights and improves the adaptability of the device.
