Towel Three-dimensional Packaging Plastic Packaging Machine Design And Key Technology Research

With the development of society and the improvement of people's living standards,towels are must for life.The use of towels is becoming more widely,and the demand is increasing yearly.With the improvement of the current production process,the production efficiency of towels has been greatly improved,and domestic towel products are exported overseas.At the same time,people pay more and more attention to the packaging of towels.However,the development of domestic packaging machinery cannot keep up with the development of the production of towels,and the packaging requirements for towels cannot be fully met.The common packaging modes currently on the market are pillow packaging(also known as sleeve packaging)and L-shaped packaging.These two packaging modes are not suitable for three-dimensional towel packaging with high thickness and the packaging has corners.The project originated from the enterprise cooperation project,and designed a new type of towel packaging and laminating mechanism for the enterprise,namely the three-dimensional multiple towels packaging and laminating machine.This paper first studies the packaging principle of the towel packaging machine,and carries on the modular analysis design according to the setting requirements of the towel shape "cuboid".The main research contents are as follows:1)Explain the research status at domestic and abroad and related research results,study the common towel packaging mode,analyze and compare the two main packaging modes,according to the towel packaging process and functional requirements,based on the modular design concept,the towel The packaging plastic package is divided into three large blocks,and based on that,the principle analysis design of each module is carried out.The design mechanism is a rotary packaging plastic package.2)Because of the soft body characteristics of the towel,it is easy to loosen and deform during transport pushing,which affects the packaging effect.Therefore,a pre-compression mechanism is added to the mechanism,and the relationship between the deformation amount of the towel and the pressure is obtained through the test.3)Analyze and summarize the traditional packaging filming methods,and propose a new packaging film adsorption traction filming method.The negative pressure adsorption pressure of the film is studied to ensure the traction tension of the film,and the film is in a tight state when the package is wrapped,so that the compressed towel is smoothly wrapped into the rotating mechanism,and the packaged film has no wrinkles.Improve the packaging efficiency of the towel machine,and the beautiful and uniformity of the towel after packaging.4)Based on packaging requirements,sealing mode is selected for this design analysis.Towels and plastic films are flammable and have a strict heat sealing temperature.Therefore,the heat seal model was established,and the professional ANSYS software was used to optimize the heat sealing temperature and heat scaling time of the film.The heat sealing effect is ensured without damaging the towel body.5)Use ANSYS and ADAMS to perform motion simulation on the mechanism to ensure the rationality of the mechanism design and ensure no interference.Reliability analysis of frequent high-speed start-up discs.Comprehensively ensure the design and simulation of the laminator to censure that the towel three-dimensional packaging laminator can achieve the "cuboid"three-dimensional type packaging shape effect,and the packaging effect is well.The packaging mechanism designed by the thesis is expected to change the development of traditional packaging machines,achieve continuous high-speed packaging,improve packaging efficiency,and increase the scale of enterprises.
