Design and Modelling of Coiler Mechanism for Mini Carding Machine

Carding is a very important process and the quality of the final yarn that we produce is very much dependent on the quality of carding and to maintain the quality of carded slivers are packaged in the form of coils. The sliver is very weak therefore the form of package should be such that it should adequate protection during handling and it should not get entangled or stretched during packaged formation. To maintain the sliver quality, the delivery speed of carding machine slightly lower than the coiler speed. This project is the outcome of the textile Industry need to design and validate a coiling mechanism for mini carding machine, as the delivery of mini carding machine doesn’t match with the existing coiling mechanism (as speed of coiling is very high). Mini carding machine needs slow speed coiling. Hence, there is a scope for designing the coiling mechanism as per the mini carding machine capacity. So that the sliver will get packaged more effectively in the sliver can. The mini-carding machine delivers 8kilograms of sliver in one hour. First the data accumulated from the existing coiler mechanism. Understood the working and design of mechanism. Mini carding machine thoroughly studied for understanding the coiler requirement. As per design data obtained and literature studied, coiler mechanism is designed and to validate the design a finite element analysis is carried out. For graphical representation 3d cad model is generated and to validate the design a finite element analysis is carried out. From the results it is observed that the design is safe for the given loading conditions.
