Generally, the sealing machine is composed of a frame, a speed-reducing and speed-regulating transmission mechanism, a sealing and printing mechanism, a conveying device and an electrical and electronic control system.
When the power is turned on, each mechanism starts to work. After the electric heating element is energized, the upper and lower heating blocks are heated rapidly, and the temperature is adjusted to the required temperature through the temperature control system. The impression wheel rotates, and the cooling system starts to cool as needed, and the conveyor belt transfers. And adjusted to the required speed by the speed regulating device.
When the package containing the items is placed on the conveyor belt, the sealing part of the bag is automatically sent between the two sealing belts in operation and brought into the heating zone. 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 by the knurling wheel (or printing wheel), so that the upper and lower plastic films of the sealing part are glued and pressed into a net pattern (or printed logo) ), 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.
