[Abstract]:Automatic vacuum thermoforming packaging machine has been developed in recent years. It is widely used in multi-function and multi-purpose packaging machine. It has the advantages of strong performance, high production efficiency and wide adaptability. The shapes of the formed containers vary, and they can be widely used in various food and non-food packaging fields. However, at present, there is little research on the cutting process that affects the final appearance quality of the packaging. The purpose of this paper is to study the cutting technology and the cutting device of the special-shaped packaging, to analyze the technological parameters affecting the cutting of the special-shaped packaging, and to put forward a new type of cutting method-copying cutting. It is used to improve the appearance quality of the product and to improve the cutting efficiency. Objective and significance. This paper mainly investigates the development of automatic vacuum thermoforming packaging machine, the existing cutting technology of thermal forming packaging machine and the problems existing in the cutting device of thermal forming packaging machine, and clarifies the significance and importance of the subject research. The main techniques and methods of the research have been determined.

On this basis, the design of the blanking device for the special-shaped parts and the analysis of the influencing factors are carried out, and the design of the punching and cutting device for the special-shaped packaging parts is completed. The process parameters affecting the quality of punching are analyzed. The design of blanking blade, blanking tool template, punching auxiliary device and blanking integral device is completed, and the blanking pressure of the main parameters of blanking is calculated. The effects of pressing speed, material properties, plywood quality and cutting quality on the pressure cylinder needed for punching and cutting are briefly analyzed. Based on this, the thermoforming packaging machine with wide width and multi-die cavity is used to determine the effect of punching speed, material properties and plywood quality. The corresponding conveying device is designed, and the punching device design of the wide width multi-die cavity thermoforming packaging machine is completed. The cutting mechanism selection and device design of the special-shaped parts are completed. According to the action requirements of the actuator in the profiled cutting process of the special-shaped packaging, The design of clamping mechanism, copying mechanism and positioning angle mechanism are completed. The parametric design and kinematic analysis of clamping mechanism are carried out, and the rational verification of copying mechanism is carried out. Kinematic analysis and optimization design; determining copying cutting time, drawing working cycle diagram, estimating production efficiency. Whole model design. Based on Solidworks 3D design software platform, single set of fixed punching device for special-shaped package, In order to test the rationality of the whole device, the high efficiency punching and cutting device with wide width multimode cavity and the copying cutting device are used to create 3D model and assemble the whole machine model to verify the rationality of the whole device.
