摘要

The present invention relates to a needle bar and a fabric pressing plate lifting device of the quilting machine.;More specifically, when the timing belt transmits the driving force of the main shaft to the cam, the thread presser and the needle lift rod connected to the cam are lifted and the lifter and the needle bar are lifted, and the fabric pressing plate is adjusted according to the speed at which the needle bar is lifted. To raise and lower, the fabric pressing plate is coupled to the lower end of the elevating rod and the elevating rod and the compression spring and elevating guide and " "The guide block of the type is composed of the support frame made by bending the steel plate," "The guide block of the rocker, which swings up and down only by a certain angle, is combined with the groove formed in the type guide block, so that the fabric pressing plate lifting rod can stably move up and down without shaking when the rocker operates.;Therefore, according to the present invention, the needle bar and the fabric pressing plate can be rotated at a high speed of 800rpm to 1400rpm or more, thereby maximizing productivity, reducing noise, and increasing durability.
