[Abstract]:This paper is supported by the research and demonstration of key technology of wood-plastic composite materials (2012BAD32B04), the key project of science and technology support in the 12th Five-Year Plan, and the research on the forming technology and equipment of vegetable composites. In this paper, the application equipment of soybean protein-celery composite paper was designed and studied. The content and work of this paper are as follows: 1) according to the design requirements of packaging machine, technical parameters and special performance requirements of soybean protein-celery composite paper as packaging materials, the technological process of packaging machine is given. According to the technological process of the packing machine, the suitable packing form and sealing mode, discharging mode and heat sealing mode are determined, and then the overall layout of the packaging machine and the transmission scheme are drawn up. Finally, it is determined that the packaging machine is mainly composed of PLC control system, power motor, gear transmission system, feeding device, film feeding device, humidifying device, longitudinal seal longitudinal cutting device, transverse seal crosscutting device and finished product output device. Through the power of the motor, the wrapping paper is sent out by the feeding device, through the humidifying device, the longitudinal sealing and cutting device is used for longitudinal sealing and cutting, and the transverse sealing and cutting device for transverse sealing and cutting, After the transverse sealing is finished, PLC gives the signal to fill the material, and finally outputs the output device by the finished product. 2) in the aspect of the executing mechanism, the screw rod of the discharging device is studied and designed. The structure parameters of the screw rod are obtained by studying the movement of the material; the structure of the hot sealing roller and the transmission shaft are analyzed and designed; the structure composition of the film feeding device is reasonably designed. In the transmission system, the transmission system of longitudinal seal, longitudinal cutting mechanism and transverse seal are designed, and the transverse seal and transverse seal are designed in the transmission system, while ensuring the structure of each mechanism is simple, compact and easy to process. (3) in the transmission system, the transmission system of the longitudinal seal and longitudinal cutting mechanism is designed, and the transverse seal and transverse seal are designed. The transmission system of the output mechanism. The eccentric sprocket mechanism in transverse seal, cross-cut and output mechanism is studied and designed. It ensures the synchronization of the vertical seal and the transverse seal in the working process of the packing machine, and the accurate sealing, realizes the high precision and high speed packing requirement. (4) using the SolidWorks 3D drawing software to draw and assemble each part of the packing machine; The static analysis of the transmission shaft, a key component of the packaging machine, was carried out by using ANSYS software to verify the rationality of the design, and the thermal analysis of the vertical sealing roll was carried out, and the heat conduction effect of the heat sealing roll during the heating process was analyzed. Finally, the packaging machine is installed and debugged.
