Design of pneumatic table tennis packing production line

Abstract: Pneumatic systems are widely used in various types of production lines, especially for the installation and transmission of lightweight parts。 In this paper, a set of pneumatic table tennis packaging production line is designed according to the requirements of the three table tennis。 The design task includes a transmission device, and sorting table tennis device for obtaining the scheme, design and check, the standard parts selection, production line control, complete the design specification and drawings drawing structure。 Through this project, it can make the students have a more comprehensive and perceptual understanding of pneumatic system, mechanical structure and pneumatic control。 The main difficulty of this project is how to simplify the design of mechanical structure without affecting the performance。 And a simpler PLC program to control the system。 There is the strength of mechanical structure is also the focus of this project。

    The first chapter is the introduction of the main topics and some background information。 What's more, the actual application of pneumatic technology

The second chapter is mainly about the design and analysis of the blanking device, and the structure of some parts is checked and checked

The third chapter mainly carries on the comparative analysis to the material fetching device's plan, carries on some essential analysis and the computation to the device structure

The fourth chapter is the comparative analysis of the rotary cylinder is still under the scheme, analyzed the structure of the device。

The fifth chapter is the design of the pneumatic loop and the selection of the components。

The sixth chapter is mainly about the electrical control of the device, PLC selection, and the design of control procedures。
