Design Of Casing Measuring Machine And Research Of Related Key Technology

Casing measuring machine is designed to measure the length of casing,this machine can be used on hog, sheep and beef casings. The field of application is broad,while there is no the corresponding equipment in the domestic. The imported equipment is very expensive, lacking of technical support. At present, workers in the domestic casing manufacturers measure the casing by manual measuring in most situations , the efficiency is low and it brings measurement error. Because the casing does not have unified measuring tool, both parties are easy to cause disputes for the metrical length is not consistent. For meeting the objective market demands of the auto-measure of casing, the topic group independently developed casing measuring machine.The main research content of the paper is the mechanical system design and manufacture, and the control system research and development. The mechanical structure mainly includes body, head, shield, driving wheel and measuring wheel. By combining PLC, touch screen and motor driver as the control system, we increase the stability, reliability of the system.Here is the following work mainly:Firstly,the market demands and the requirements of manufacturers, the whole structure plan of the casing measuring machine is drown up in this paper. Secondly, in order to overcome the slip and errors in the measurement of the length of the casing, tooth groove and toggle switch of measuring wheel have been designed. 3D model of every spare part of the casing measuring machine was set up using SolidWorks project software.Meantime,the relative relation between the movement parts is analyzed.Then,the entire machine assembly body model is established,the interference examination and the assembly sequence rationally was made.And assembly animation is produced.Thirdly, in order to guarantee the control process with high precision, high stability and high reliability. Through the configuration software, user interface shows simple and intuitive, and the operator is convenient to use.Fourthly, when the mechanical and control system software and hardware design is completed, the casing measuring machine was installed and tested, The practical application results show that the system has attained its design requirements.Casing measuring machine has a novel design and a reliable function. The length of the casings can be controlled to within 1 cm, It realizes the automatic and accurate measure. The success of casing measuring machine fills the gap while there is no related measuring equipment about casing. It would contribute to casings market standardization and it has good values of practicality and spread.
