| The roving process for a spinning factory of spinning process,but any enterprise will have a large number of roving roving bobbin or unqualified remaining tail,unqualified roving roving including uneven adhesion,roving unevenness mostly appeared in drawing fault,roving adhesion is because of wool with felting in the process of transportation,or placed in the fiber to produce mutual transmission,although the amount is not large,can also cause difficulties for fine spinning,roving as if these waste material treatment for enterprises is a big waste,if you continue to use,will cause the difficulty of repair to the finishing process is finishing,design and development of a fully automatic roving unwinding conditioning machine,most of the roving unwinding and can continue to be used in spinning,if the entire batch of roving drafting errors,but also from the combing needle reuse,bobbin The rest can be returned through synthesis of a large winding roving,do so to improve the efficiency and quality of the use of spinning,has practical application value.Through to the domestic and foreign textile equipment investigation,there is no roving unwinding conditioning machine or similar function device in the spinning process,as long as there is unqualified or the remaining tail roving bobbin as back hair,then developed a roving unwinding conditioning machine to reduce roving consumption,eliminate waste,but also improve the in the textile industry equipment intermediate process has important significance.This paper designs the Fully Automatic Roving-Rewind Machine and the core work includes the mechanical part design,control system design and research of roving process unevenness.The way to work of the machine and the design part mainly including the overall framework,roller,clamping arm,transmission mechanism,and auto-alignment machine.The overall framework of the machine made by Shandong Ruyi textile group,the auto-alignment machine is derived from the eliminated PB32-Combing machine made in Italy,and other parts come from FR2A-Roving frame which has eliminated.After collect all parts,the machine can debugging and use.The design of the control system mainly includes the design and installation of main circuit and control circuit,control circuit of programmable controller PLC,servo device,selection and installation of the servo motor.Programmable controller PLC program design and debugging is the difficulty of design,program contains the control of the machine,the self regulating expression control,control of automatic stop,command set to receive and control of other conditions.Study on the process of roving evenness,is on the design and verification of roving unwinding machine using the following.The design is completed,Shandong Ruyi spinning factory as long as there are no uniform tops,will be in the unwinding of roving unwinding machine,from low to high count wool wool products supporting products,the success of the unwinding machine design is verified from high to low a wool wool products are all products.The operator love to use,because the unwinding machine is easy to use,easy to operate,it is more important to improve the efficiency of uneven product reuse,but also reduce the consumption and the income of employees is also a corresponding increase.Shandong Ruyi spinning mill equipment capacity is 36 thousand pounds,according to the use of the past two years,the average of a class(8 hours)about 10 kilograms of unevenness,the unevenness of roving unwinding,need to design 4 spindles can meet in unwinding.If equipment capacity expansion,can be expanded in accordance with the corresponding multiples.Through various product validation,this machine has been used in the production and has obtained the good effect... |
