Device for controlling material quantity stability

The utility model belongs to the technical field of mechanical equipment, and particularly relates to a device for controlling material quantity stability. The problems that an eccentric shaft of a vibration motor is damaged and a bolt slips due to the fact that the amplitude of the vibration motor is frequently debugged when the change of the material quantity is controlled by debugging the amplitude of the vibration motor are solved. The feeding device comprises a feeding groove and a feeding hopper arranged above the feeding groove, and a batching module for adjusting the material quantity through sliding is arranged at an outlet of the feeding hopper, so that the problem that an eccentric shaft and a bolt of a vibration motor are damaged due to the fact that the vibration motor is frequently debugged is avoided. 本实用新型属于机械设备技术领域，具体涉及一种控制料量稳定的装置。解决了控制料量变化的方式为调试振动电机的振幅，经常调试振动电机的振幅会损坏振动电机的偏心轴、螺栓滑丝的问题。本实用新型包括给料槽，以及安装给料槽上方的进料斗，其中，在所述进料斗的出口处配设有通过滑动调节料量的配料组块，其目的在于，避免经常调试振动电机导致振动电机的偏心轴、螺栓滑丝损坏。
