The punching and positioning device for the upper and lower rail brackets of the rotary tablet press and its components

Abstract

The invention provides a punching positioning device for an upper guide rail support and a lower guide rail support of a rotary tablet machine and components of the upper guide rail support and the lower guide rail support. By setting the upper guide rail support, the lower guide rail support, a rotary plate for mounting and fixing the upper guide rail support and the lower guide rail support and a substrate for mounting the rotary plate, the punching positioning device for the upper guide rail support and the lower guide rail support of the rotary tablet machine and the components of the upper guide rail support and the lower guide rail support can realize accurate positioning, the machining precision of the upper guide rail support, the lower guide rail support and the components of the upper guide rail support and the lower guide rail support is high, and thus under the working condition, the upper guide rail support, the lower guide rail support and the components of the upper guide rail support and the lower guide rail support can realize coordinated combination and assembly, so that tablets formed through pressing are unified in specifications and high in qualified rate; moreover, due to high precision of components and parts machined by the positioning device, in the production and assembling process, the components and parts are higher in interchangeability, and the requirements of industrialized production and maintenance are better met.

Description

technical field [0001] The invention relates to a punching and positioning device for an upper and lower guide rail bracket of a rotary tablet press and its components, and belongs to the technical field of tablet press component processing. Background technique [0002] Rotary tablet press is mainly used for tablet processing in the pharmaceutical industry to press granular media into round, special-shaped or tablets with text, symbols or graphics, and is the basic equipment suitable for mass production. [0003] The rotary tablet press includes a machine base, a driving device, a turntable, a feeding mechanism, a die, an upper and lower guide rail, a tablet discharge guide mechanism, and an upper and lower pressing wheel; among them, the driving device, the feeding mechanism, the upper and lower guide rails, the tablet discharging guide mechanism, and the upper and lower pressing wheels Fixedly connected to the frame, the punching die includes an upper punch, a lower punch...

AI Technical Summary

Problems solved by technology

However, in the tablet production process, the high-speed rotary tablet press is often due to the uncoordinated assembly of the upper and lower guide rail brackets and the assembly of the guide rail bracket series components, which causes the movement trajectory of the upper punch and the lower punch to deviate from the design trajectory, resulting in a gap between the cyclic actions. The incoordination of the conversion causes the sound of the whole machine to run abnormally, and the parts are damaged, which in turn leads to the failure of the final compressed tablet

In addition, in the production and assembly process of the rotary tablet press in the prior art, the interchangeability between the parts is poor, which cannot meet the requirements of industrial production and maintenance.
