Shanghai launched a self-erecting bag making machine

Shanghai Light Industry Equipment (Group) Co., Ltd. Light Industry Machinery Factory has recently developed a SDL400 automatic bag making machine that functions to produce self-supporting bags.
The SDL400 automatic bag making machine successfully developed by the factory adopts the frequency converter to control the main motor. The material motor speed, the two AC servo motor control film pulling length, the pressure of the machine traction rubber roller and the whole gravity are all passed by the cylinder through the pressure regulating valve. It is controlled to achieve the purpose of flexible gas control plastic film. In the field of electrical appliances, computer-controlled servo motor and signal processing are used to make two servo motors achieve the same effect of stopping at the same time when traction, and the magnitude of the unwinding tension is controlled by decremental analog control of the current of the magnetic caliper brake. The man-machine interface system shows the most simple control features, makes the size of the bag unwinding tension, adopts the man-machine interface system exhibition and simple control features, so that the bag length, bag making speed, number of alarm bags, working methods, etc. Column data settings and display are entered and displayed through the touch screen.
In addition to producing self-supporting bags, the SDL400 automatic bag making machine can also produce self-sealing bags, three-side sealing bags, and bag making with high positioning accuracy, high bag making speed, good tension control, stable material discharge, low noise, and stable performance. The finished bag has a smooth appearance, is very scratchy, has a beautiful appearance, and has a high heat sealing strength. It is an ideal substitute for imported products in the flexible packaging industry. According to experts, the new products developed by the plant in recent years, the main performance indicators have reached the level of similar international products.
