多頭高速壓片機多通道壓力檢測及廢品檢出（本科畢業(yè)論文設(shè)計）
摘 要

壓片機屬于制藥機械，是用于片濟(jì)藥品生產(chǎn)的專用設(shè)備。壓片機壓力檢測主要是對藥片重量和厚度的測定，從而判斷藥片是否合格。通常的壓力檢測系統(tǒng)不可以檢測每粒藥片，并且作為衡量產(chǎn)品質(zhì)量的方法，壓力與重量和厚度的關(guān)系并不是十分穩(wěn)定。因此，設(shè)計一套更加完善的壓力檢測系統(tǒng)具有十分重要的意義，實現(xiàn)在線剔除不合格產(chǎn)品。
本文研究了壓片機的工作原理、結(jié)構(gòu)特征、幾何參數(shù)、壓片機壓力檢測系統(tǒng)、壓片機沖頭和模具等部分的性能。通過對壓片機工作原理、結(jié)構(gòu)特征的研究，以及和國外同類產(chǎn)品的性能結(jié)構(gòu)比較，對不足之處做了相應(yīng)改進(jìn)，設(shè)計了壓片機工作原理圖和結(jié)構(gòu)圖。并提出了在高速壓片工況下檢測單藥片藥品壓力的簡便方法。

ABSTRACT

It is the pharmacy machinery to press one slice of machines, is used in slice helping dedicated device that medicines produced. It is mainly to the tablet weight and determination of thickness to press one slice of machine pressures and measure, thus judge whether tablets are qualified. The common pressure detection system can not measure each tablet, and is regarded as the method to weigh product quality, the relation between pressure, weight and thickness is not very steady. So, design a set of more complete pressure detection systems to have very important meanings, realize that rejects the subquality product online.
This text has studied the operation principle, structural characteristic, geometirc parameter of pigeonholing a machine, pigeonholed the detection system of a machine pressure, pigeonholed some performance such as a machine drift and mould. Through to pressing the research of a machine operation principle, structural characteristic, and compare with performance structure of the foreign like product, have improve the weak point correspondingly, has designed one slice of machine operation principle pictures and structure chart of pressing. Have got out of and measured the pressure simple and convenient method of single tablet medicines under the circumstances that the high speed presses one slice of operating modes.


Key words：Pressure machine，Pressure Monitoring，Tablet，Principle
