How Sealing Machine Works | Sealing Machine

The working principle of the sealing machine is generally composed 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. After the electric heating element is energized, it heats up, so that the upper and lower heating blocks heat up sharply, and are adjusted to the required temperature through the temperature control system. The imprinting wheel rotates. And adjusted to the required speed by the speed control device. When the package containing the articles is placed on the conveyor belt, the sealing part of the bag of the sealing machine is automatically sent between the two sealing belts in operation and brought into the heating area, and the heat of the heating block is transmitted to the bag through the sealing belt. In the sealing part, the film is heated and melted, and then passes through the cooling zone to appropriately reduce the surface temperature of the film, 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 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. | Sealing Machine
