Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pharmaceutical production equipment more specifically, relate to a kind of tablet discharge passage block detection equipment. BACKGROUND

[0002] The most common problem in tablet production is tablet jamming, which refers to the process of tablet discharge in the tablet discharge passage. Because the tablet container connected to the tablet discharge passage has been stacked full or the tablet discharge passage is too narrow to make the tablet stuck in the tablet discharge passage, so that the tablet cannot fall and jam. If such failure cannot be handled in time, the jammed tablet will be stacked along the tablet discharge passage into the feeding shoe, and the tablet will be broken by the stirring device and filled into the middle die hole. The middle die hole that should be filled with powder will be filled with broken tablets, which will cause the pressure overload of the tablet press during the pressing process, and damage the die and equipment.

[0003] The existing tablet jamming sensor needs to be inserted into the tablet discharge passage for detection. When the equipment is removed from the discharge chute, the tablet jamming sensor needs to be removed first, which affects the disassembly efficiency of the tablet press. At the same time, the dust generated during the operation of the tablet press covers the tablet jamming sensor, which interferes with the detection of the sensor and causes false alarm. Therefore, the existing tablet jamming sensor has relatively poor practicability.

[0004] In summary, how to improve the practicability of tablet jamming sensor is a problem that needs to be solved by the technical personnel in the field at present. UTILITY MODEL CONTENT
