PE Sheet Pipe Internal Heat Pressure Sealing Technology Research And Key Components Design

With the introduction of "Made in China 2025",China’s manufacturing industry has been transformed from big to strong,in which the light industry has a pivotal role in "Made in China",and tends to develop towards high efficiency,high quality,low energy consumption and environmental friendliness.The thesis combined with the technical needs of the cooperative enterprise Zhejiang Rigo Intelligent Machinery Co.,Ltd.to design a double-hose filling and sealing machine on the basis of the single-hose filling and sealing machine for the technical problems of low efficiency and low speed of sealing,from single-hose to double-hose filling and sealing machine,not simply replacing one filling head with two filling heads,but higher technical requirements for the design framework of the whole machine,transmission,handling,etc.The internal heat sealing part of the filling machine was optimized and designed to achieve the following research results and conclusions:1.On the basis of the existing single-hose filling and sealing machine of the cooperative enterprise,the three-dimensional modeling software was used to establish the threedimensional model of the double-hose filling and heating sealing machine,analyze the working principle of the filling and heating sealing machine as well as the process flow of heating and sealing,theoretically analyze the shortcomings of the existing equipment,and clarify the main research content and research objectives of the subject.2.In order to ensure the fast and stable operation of the heating and sealing mechanism,the heating,sealing,tail shearing and topping mechanisms are designed,and the fluid simulation analysis of the heating mechanism is based on the fluid simulation software,and the specific parameters are given to determine the heating time.3.Based on the mechanism principle and process analysis of heating and sealing tail shearing,the working cycle diagram of the heating and sealing tail shearing mechanism is optimized.Combined with the cam mechanism design theory,the cam profile curve and structure size of the driving cam of each mechanism are designed.4.The tail seal cylinder and cam splitter are selected,the tail seal mechanism is simulated statically and dynamically to obtain the displacement,velocity,acceleration and other parameters of key components,and to analyze whether the tail seal mechanism can complete the action without interference within the specified time,so as to verify the rationality of the tail seal model.The heating and sealing parts of the double hose filling and heating and sealing machine designed in this paper can complete the heating and sealing work within the working time,which improves the production efficiency of the filling and heating and sealing machine to a certain extent and reduces the production cost of the enterprise,and has high practical value.
