[0002] In the process of industrial production, it is often necessary to count and pack the products on the assembly line. Due to the defects of missed counting, wrong counting, high labor intensity and low packing efficiency in the traditional manual operation process, more and more automated operations are being used as the level of automation control continues to improve. As an important part of the automated packaging process, the use of automatic product packing can play a very significant role in improving product quality and production efficiency, eliminating operational errors and reducing labor intensity.

[0003] In order to ensure the packing effect of articles, the Chinese patent document with announcement number CN105857756A discloses an automatic weighing and packing device for powdered active products, which is composed of a roller conveyor line, a feeding weighing device, a vibration platform, an auxiliary device, and a finished product packaging table.

[0004] However, although it uses a shaking piece installed in the gap between the rollers for vibration, it requires additional power design, and the shaking piece and the roller that conveys the material are designed independently and do not work in conjunction, resulting in a complex structural design and easy interference with the roller during operation, thus causing malfunctions. Summary of the invention

[0005] In order to solve the technical problems raised in the background technology, the present invention provides a mechanism for leveling boxed bulk materials.
