The invention discloses a
yarn clamping mechanism for a
spinning machine. The mechanism comprises a base, a lifting cylinder is arranged on the base, a lifting column is arranged in the lifting cylinder, a
hydraulic cylinder is arranged at the lower end of the lifting column, a foundation
bed is arranged at the upper end of the lifting column, a clamping frame with the hollow inner portion is arranged on the foundation
bed, a
yarn passing wheel is arranged in the clamping frame, a
yarn passing groove is formed in the wheel surface of the yarn passing wheel, a yarn clamping lifting hole with threads is formed in the upper end surface of the clamping frame, a yarn clamping lifting rod is internally connected with the yarn clamping lifting hole through the threads, a yarn clamping sliding rodis arranged at the lower end of the yarn clamping lifting rod, a yarn clamping installation hole is formed in the upper end of the yarn clamping sliding rod, the lower end of the yarn clamping lifting rod is fixed into the yarn clamping installation hole through a bearing, yarn clamping lifting grooves fixed to the clamping frame are formed in the two sides of the yarn clamping sliding rod, a yarn clamping support is arranged at the lower end of the yarn clamping sliding rod, a yarn clamping wheel is arranged at the lower end of the yarn clamping support, and a tensioning device is arranged on the foundation
bed. By means of the yarn clamping mechanism, yarn can be effectively clamped all the time, the use ratio of the
machine is improved,
machine halts are reduced, and clamping force onthe yarn and the tensioning degree of the yarn can be adjusted.
