1. The machine is composed of a frame, a decelerating and speed-regulating transmission mechanism, a heating and radiating mechanism, a sealing and printing mechanism, a conveying device and an electrical and electronic control system.
2. Turn on the power, and all agencies start to work. After the electric heating element is energized, it heats up, so that the upper and lower heating blocks are heated up sharply and adjusted to the required temperature through the control system; the impression wheel rotates; the cooling system starts to cool as required; the conveyor belt is transferred and adjusted to the required speed by the speed control device.
3. When the package containing the items is placed on the conveyor belt, the sealing part of the bag is automatically sent to the two sealing belts in operation and brought into the heating zone, and the heat of the heating block is transferred to the sealing part of the bag through the sealing belt , The film is heated and melted, and then passed through the cooling zone to make the surface temperature of the film drop appropriately, and then rolled through the knurling wheel (or printing wheel), so that the upper and lower plastic films of the sealing part are bonded and pressed into a net pattern (or printing). Mark), and then the sealed packaging bag is sent out of the machine by the guiding rubber belt and the conveyor belt to complete the sealing operation.
