The thick material sewing machine is indispensable in the production process of container bags. This kind of equipment can almost sew common packaging bags. Because the common sewing machine often has the phenomenon of machine jam, this phenomenon basically occurs in sewing relatively thick packaging bags. Using this kind of machine can basically avoid these problems.
Although this kind of container bag sewing machine is an upgrade of the ordinary version, it is inseparable from the four working mechanisms. Among them, the looseness, recovery and tightening mechanism of jumper mechanism are the key facilities in the equipment.
Each working cycle of jumper bar of heavy material sewing machine is responsible for the retraction and release of the surface thread. At the same time, it also cooperates with the cloth feeding mechanism to form the corresponding stitch.
The working characteristic of the thread take-up mechanism of heavy material sewing machine is that the thread take-up rod hole moves up and down, and the motion curve is like a branch leaf. When the thread take-up rod moves down, one is to supply thread to the descending needle; Second, when the shoe-making sewing machine's rotary hook catches the top thread, it supplies the top thread to the rotary hook until the top thread bypasses the shuttle center frame.
Only the cooperation between these equipments can produce qualified container bags.
