[0004] However, it still has the following disadvantages in actual use:

[0005] The existing new weighing powder packaging machine detects the weight of the powder inside the powder packaging bottle through a weight sensor during use, and displays the relevant data on a digital display screen, so that the staff can know the weight of the powder inside the powder packaging bottle by watching the digital display screen. At the same time, the staff needs to use their feet to operate the foot valve to control the electric valve, so as to adjust the powder discharge state. In this way, the staff needs to work highly concentratedly and the skills of the staff are limited, which will cause the electric valve to open and close in time, resulting in excessive or insufficient powder discharge, which will reduce the packaging quality of the powder.

[0006] 2. In the existing new weighing powder packaging machine, when in use, the electric valve connected to the side wall of the discharge pipe is opened, so that the powder in the storage hopper falls downward into the inside of the powder packaging bottle, and the powder packaging bottle moves with the downward movement of the weighing platform, which will cause the lower end of the discharge pipe to have poor contact with the powder packaging bottle, and the powder will float due to the influence of external wind, thereby increasing the waste of powder and causing damage to the surrounding working environment.

[0007] To this end, we provide an automatic weight check device for a powder packaging machine to solve the above problems. Utility Model Content
