[0002] Round bottom bags are also often called bottom seal bags, stand-up bags or standing bags. They are a popular design in modern packaging solutions. The bottom of this bag is round, which can make better use of the internal space than flat bags. It is especially suitable for powdered, granular or liquid products, and can be filled with more contents. Round bottom bags are widely used in various packaging scenarios due to their good self-supporting properties and high space utilization.

Vertically distributed brackets 8 are welded and fixed on both sides of the mounting plate 6, and a regulating component for adjusting the inclination angle of the rocker arm 9 is provided on the bracket 8. The conveyor belt 2 of this structure can reversely sleeve the round-bottom bag after production on the outside of the round seat 3. When the round seat 3 is transported to the position corresponding to the hot pressing plate 7 on the conveyor belt 2, the hydraulic cylinder 5 can drive the mounting plate 6 to rise and fall so that the hot pressing plate 7 can perform hot pressing treatment on the bottom of the round-bottom bag sleeved on the round seat 3, and after the hot pressing plate 7 completes the hot pressing, the regulating component on the bracket 8 can drive the rocker arm 9 to tilt in real time. When the rocker arm 9 tilts, it can drive the roller 10 to roll along the top of the round seat 3 to further smooth the bottom of the round-bottom bag to ensure that the bottom of the round-bottom bag is flat and wrinkle-free. The method of automatic smoothing of the bottom of the bag is more time-saving and labor-saving, and has higher efficiency. It can also achieve uniform standards for the flatness and shape of the bottom of each bag, solve the inefficiency and inconsistency of traditional manual operations, and reduce labor costs and pollution risks. The adjustment components on the bracket 8 include a cylinder 81, a push block 82, and a coupling 83. The cylinder 81 is fixed to the outside of the bracket 8 by bolts, and the push block 82 is fixed to the output end of the cylinder 81. A vertical opening is provided on the bracket 8, and the push block 82 extends to the inside of the bracket 8 through the vertical opening on the bracket 8. The coupling 83 is connected between one end of the push block 82 and the bottom end of the rocker 9. When the cylinder 81 of this structure is driven, the push block 82 will move vertically on the bracket 8. When the push block 82 moves vertically, the rocker 9 can be adjusted by the coupling 83. The bottom end is linked to achieve the function of adjusting the tilt angle of the rocker 9 in real time. The connection between the coupling 83, the push block 82 and the rocker 9 is hinged by a pin shaft, and a spring member 12 is also connected between the upper end of the coupling 83 and the upper end of the rocker 9. The rocker 9 of this structure will synchronously drive the spring member 12 to move when it moves, which is beneficial to improve the stability of the rocker 9 when it moves, so that the roller 10 has a better effect in smoothing.

The arc block 11 of this structure can be retracted and extended to both sides of the round seat 3 by the retracting rod 15 in the retracting hole 16. In this way, the arc block 11 can support some round bottom bags that need to be smoothed (such as round bottom bags made of canvas), which can further ensure the effect of smoothing the bottom of the round bottom bag.

[0019] Working principle: When using the special production line equipment for round bottom bags, firstly, a number of support rings 17 are fixed on the conveyor belt 2 by bolts at intervals and the round seat 3 is installed. Then, the arc block 11 is retracted and extended to both sides of the round seat 3 through the retracting rod 15 in the retracting hole 16 until the arc block 11 moves to a suitable position. Then, the round bottom bag after production is reversely sleeved on the outside of the round seat 3. When the round seat 3 is transferred to the position corresponding to the hot pressing plate 7 on the conveyor belt 2, the hydraulic cylinder 5 is started. When the hydraulic cylinder 5 is driven, it will drive the installation plate 6 to rise and fall. When the installation plate 6 rises and falls, it will bring The movable hot pressing plate 7 performs hot pressing treatment on the bottom of the round bottom bag mounted on the round seat 3, and when the hot pressing plate 7 is recovered upward to a suitable position after completing the hot pressing, the cylinder 81 of the regulating assembly on the bracket 8 is started. When the cylinder 81 is driven, it drives the push block 82 to move vertically on the bracket 8. When the push block 82 moves vertically, it generates a linkage with the bottom end of the rocker arm 9 through the coupling 83. When the rocker arm 9 is tilted, it drives the roller 10 to roll along the top of the round seat 3 to further smooth the bottom of the round bottom bag, so as to efficiently smooth the round bottom bags in batches, thereby completing a series of tasks.
