Sealing machine working principle and structure introduction

The general sealing machine is composed of a frame, a speed reduction transmission mechanism, a sealing printing mechanism, a conveying device and an electrical and electronic control system.

When the power is turned on, each mechanism starts to work, and the heating element is heated after being energized, so that the upper and lower heating blocks are heated up sharply, and the temperature is controlled to the required temperature by the temperature control system, the printing wheel rotates, and the cooling system starts to cool as needed, and the conveyor belt is sent, And adjusted by the speed control device to the required speed.

When the package containing the article is placed on the conveyor belt, the sealing portion of the bag is automatically fed between the two sealing tapes in operation and brought into the heating zone, and the heat of the heating block is transferred to the sealing portion of the bag through the sealing tape. The film is melted by heat, and then passed through the cooling zone to appropriately lower the surface temperature of the film, and then rolled by a knurling wheel (or a printing wheel) to bond the upper and lower plastic films of the sealing portion and press the mesh pattern (or printed logo) ), the sealed bag is sent out of the machine by the guiding rubber belt and the conveyor belt to complete the sealing operation.
