Abstract: Simulation studies were carried out on the shaft of carpet tufting machine to establish multi-parameter dynamic balancing equations based on Matlab. Through the analysis and comparison of reaction forces between link and spindle before and after dynamic balancing, the optimal parameter solution was acquired under the ideal state. According to the actual situation in the project, the optimum value was obtained by modifying some parameters, which not only made mechanism achieve a better balancing, but also enhanced the transmission of motion performance and improved the operating environment of spindle system.

Abstract: The needle bar transverse shifting will likely form the stop mark liked gap on the tufted carpet. This paper proposed the yarn feeding compensation scheme and illustrate implement method in detail. Through analysis the change in yarn feeding path and loop pile forming of carpet tufting machine, construct the mathematical model of length change of yarn feeding in path and usage of loop pile forming while needle bar shifting. According to the mathematical model for yarn feeding compensation, calculate the additional yarn feeding requirement. Base on jacquard control principle, dynamic control the yarn feed actuator to drive the yarn feed roller to delivery additional length yarn, and produce loop pile with predefined pile height, Test result show the compensation is feasible.

Abstract: During weaving tufting carpet, the improper stop position of tufting machine will result in stop mark, which influences the carpet quality. In this thesis, through theory analysis and experiment research, the influence rule on the stop position of tufting machine to loop yarn tension and to loop-height has been obtained, and a method of eliminating stop mark by stopping machine in high has been put forward. The technology experiment has proved that when it overlaps partly with high position signal, a fixed position of stopping tufting machine in high has been realized by sending out stop instruction and stopping the tufting machine by a brake cylinder, and the best result of eliminating stop mark has achieved.
