The structure of sealing machine

Generally, the sealing machine consists of a frame, a deceleration and speed regulation 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. The electric heating element is heated after being energized, causing the upper and lower heating blocks to heat up sharply, and is adjusted to the required temperature through the temperature control system. The imprinting wheel rotates, and the cooling system starts cooling as needed. The conveyor belt rotates. 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 running sealing belts and brought into the heating area. The heat of the heating block is transmitted to the sealing part of the bag through the sealing belt. The film is heated and melted, then passes through the cooling zone to lower the surface temperature of the film appropriately, and then is rolled by a knurling wheel (or printing wheel) to bond the upper and lower plastic films of the sealing part and press out a mesh pattern (or print logo) ), and then the sealed packaging bags are sent out of the machine by the guide rubber belt and conveyor belt to complete the sealing operation.
