Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of food and drug processing equipment, and particularly to a telescopic positioning shaft structure. BACKGROUND

[0002] The whole particle machine is a machine for processing uneven material into target particles. The whole particle machine is internally provided with a rotating part. When the material enters the gap between the rotating part, it will be subjected to strong extrusion force and shearing force, thereby being broken into smaller particles. The whole particle machine is mainly applied in the fields of pharmacy, food, and chemical industry.

[0003] The rotating part needs to be supported at both ends of the central shaft to ensure reliable rotation. Since the whole particle machine needs to be cleaned and maintained frequently, the door cover at one end of the rotating part needs to be frequently disassembled. When the rotating part is reassembled, the rotating part needs to be positioned. However, the existing rotating part positioning shaft structure is not telescopic, which causes the rotating part and the positioning shaft structure to be rigidly connected, resulting in inconvenience in reassembling the rotating part.
