Loading depth fine adjusting device for tablet press

Abstract

A loading depth fine adjusting device for a tablet press comprises a worm, a worm support, a helical gear and a fixed thread bushing. The fixed thread bushing is sleeved on a piston rod of a lower hydraulic cylinder and fixedly mounted on the upper end face of a lower fixed plate, the outer periphery of the fixed thread bushing is provided with an external thread, an inner hole of the helical gear is provided with an internal thread, and the helical gear is screwed onto the fixed thread bushing through the internal thread on the helical gear. The worm is fixed onto the worm support which is fixedly mounted on the lower fixed plate, the worm is meshed with the helical gear, and the height of the helical gear is larger than or equal to that of the fixed thread bushing. The fine adjusting device is capable of precisely fine adjusting the distance between a lower moving plate and the lower fixed plate, and is simple in structure, reasonable in stress, simple and feasible in adjustment, high in control precision, wide in adjusting range, economical practical, and capable of overcoming the defects of the prior art.

Description

Technical field: [0001] The invention relates to a tablet press, in particular to a device for adjusting the filling depth of the tablet press. Background technique: [0002] At present, tablets are becoming more and more common, and the fields where tablets are used are expanding, and the market demand for tablets is increasing year by year. Tablets are made by pressing powder or granules through high-pressure molding with a tablet press. The existing tablet press machine can press granular and powdery raw materials into tablets of various shapes. It can press large-scale products, and at the same time it can have multiple tablets in one mold. It can be used in large-scale production industries. The mold is easy to replace and install, and the operation is simple and easy to learn. Existing tablet presses such as figure 1 As shown, it includes an upper fixed plate 1, an upper movable plate 2, a middle fixed plate 3, a lower movable plate 4, a lower fixed plate 5, four gui...
