TRANSMISSION MECHANISM FOR THREE NEEDLE SEWING MACHINE OF LONGITUDINAL TYPE CYLINDER BED

摘要

relates to the design of a vertical cylinder powertrain samchim bed sewing machine , two output power of the machine spindle delivered to the eccentric wheel is installed upstream of coaxial and two species cantilever swing arm set and one of the machine through the transverse axis arrangement , whereby each decorated by driving the upper shaft of the needle bar drive shaft installed in the front end by a cantilever that interaction occurs each other this stable sewing operation prevents the vibration of the machine bed , and will be done , so that favorable sewing tasks at the same time driving at high speed , the transmission mechanism is working stroke of the needle bar linkage to the drive shaft can be adjusted in a timely manner in accordance with the sewing water thickness was .
