Description

Technical Field

[0001] The utility model belongs to the technical field of medicine production equipment, and specifically relates to a medicine rejecting device. Background Art

[0002] The packaged medicines are inspected by weighing them to determine whether their weight is within the normal range. If the weight of the medicine is not within the normal range, it will be kicked out of the conveyor belt by the blowing head when passing through the blowing head, completing the quality inspection of the medicine.

[0003] When the conveyor belt is changed to transport medicines of other shapes, it is necessary to raise the height or adjust the blowing direction to better remove unqualified medicines. In the existing technology, the blowing head is generally fixed on one side of the conveyor belt, and the position of the blowing head is relatively fixed to the position of the conveyor belt. When adjusting the blowing head, it is necessary to remove the fixings, raise the height, adjust the blowing direction, and finally fix the blowing head with the fixings. The operation is complicated in the process of adjusting and fixing the blowing head, and it is impossible to achieve convenient and flexible adjustment of the blowing height and position.
