The machine has the advanced microcomputer controlling system. All the parameters will display on LCD at real time.The temperature controlling system,tensility controlling system,erro-correcting controlling system,photoelectricity tailing system.The whole machine is run with the advanced three step driving system.Longitudinal-sealing device is made up of knockdown pressing structure and cooling componet.The cooling device is water-tank wind cooling automatic circling system.The center tensility is checked up by the floating roller.The compensate capacity is controlled by the microcomputer so as to ensure the nicety and siting precision of sidelong sealing.The cutting device ensures the order liness of the endlong sealing side.The hole-punching and tearing punching device;Pneumatic synchronism,different step delivering device can carry out N times sending;It can increase the heat sealing times and hole-punching times according to the demand of the customers;As we keep on researching and developing,the factory keeps down the rights of changing designs.
