Design And Development Of Threading Machine For Carrier Bags

This project is applied to the field of carrier bags threading.This operation is done by manpower at present,and manual operation will lead to a series of problems,such as low production efficiency,poor quality stability and easy to cause deformation and damage of bag body.At present,in carrier bags threading field,there is no packaging machine that can solve the problem of carrier bags threading.There is no carrier bags threading machine for production.Therefore,the development of the carrier bags threading machine will solve the bottleneck of carrier bags production,thereby saving production costs and improving production efficiency.According to the market demand,the design scheme of the carrier bags threading machine is carried out.The specific process flow is:the horizontal mechanical grabber grabs the rope and passes through the cladding institution for cladding rope,at the same time,the carrier bags is dragged forward by the conveyor belt,each block pushes a carrier bag;after cladding the rope,the rope continues to move forward,the crosswise gripper grips the rope after returning,after the rope head is conveyed to the air cylinder,at this point,the knife cut the rope;at this point the air cylinder is drawn from both sides of the carrier bag and kept open,at last the gripper on the cross guide grasps the cutted rope for threading operation.Cycle diagram is designed at the same time,and coordinating the movement of institutions in time and space.The process will reorganize the carrier bags threading mechanism and cladding rope mechanism,it is not only improves production efficiency,but also realizes higher level of production automation.On the basis of the design of the scheme,This subject uses computer aided software to establish and assemble the 3D model of parts and components.The machine is divided into several modules,such as threading mechanism,cladding rope mechanism,carrier bags transporting mechanism and so on.Among them,the threading mechanism is also divided into support part,threading part and rope cutting part;caldding rope institutions are divided into support parts,cladding rope machines,cladding machine fixed plates,etc.The carrier bags transport mechanism is mainly divided into carrier bags conveyor,feeding and receiving parts of carrier bags.After the establishment of each organization model,the assembly is completed,and the establishment of virtual prototype is completed.According to the principle of machine technology,the process of control system and the composition of control system are determined.The way of combining programmable logic controller and touch screen is adopted,to realize automatic control and operation process monitoring for machine.Motor and other control elements are selected according to the needs of institutions.Finally,the parts are processed and assembled according to the engineering drawings,The components of the control system are installed and connected.At last,a mechanism is assembled to prototype and debug the prototype.
