| 1.Brief Introduction to the Machine¡¡¡¡ FH-58 tobacco leaf and vegetable leaf sewing machine adopts the method of complex feeding with single straight machine needle, crochet hook catching thread and upper and lower conveyor belts.It is easily operated, making chain type thread trace.Because our machines adopt special upper feeding framework, autorotation driving device and free-exalting swaging device, any kinds of tobacco leaves and vegetable leaves can¡¯t be damaged, which can¡¯t be accomplished by ordinary sewing machines.Besides, huge lower conveyor belt feeding device can feed the materials to the upper feeding framework so that the chain type sewing can be done.With the upper feeding framework and lower feeding conveyor belt, the upper and lower feeding amounts accord with each other perfectly.At the time of height overlapping sewing and climbing sewing, rapid feeding, stable needle gauge and level beautiful thread trace can be achieved.When sewing thick materials, the performance is excellent with easy operation.Meanwhile, it can be adjusted according to certain requirements of sewing techniques.Stems and leaves of all kinds of crops, such as tobacco leaves, vegetable leaves, radish leaves, dried sweet potato, capsicum and other fresh vegetables products, can be sewn in chain style. This thread trace is easily dismantled with a slight pull.As for drying and air drying of crops, it can substitute handwork because the efficiency is scores of times higher than that of handwork, thus liberating labor force to a great extent and bringing benefits to the peasants. 2. It is suitable for the in-line sewing of tobacco leaves, vegetable leaves, radish leaves, dried sweet potato, capsicum and other fresh vegetables products. 3. Main Traits Adopting the method of complex feeding with the upper and lower conveyor belts and free-exalting presser foot, it can ensure the thread trace sewing of tobacco leaves, vegetable leaves and other fresh vegetables products within the rating range of any needle gauge.The noise of the machine is reduced and the life span is lengthened by adopting the advanced hi-tech techniques such as double reduction gearbox, eccentric driving thrust framework and one-way thrust framework. 4.Tips for Use and Maintenance 1) Rust preventive oil and dust on the new or long stored machines should be removed before use.Inpour several drops of sewing machine oil onto the running and gliding parts and keep the machine running for several minutes. 2) When running, the machine runs counterclockwise in the direction of the dynamo. 3) The choice of needle and thread should be proportional to the materials to be sewn. 4) Remove the dust on the machine and lubricate wholly with oil every four hours of working. 5) Main Technique Specifications
