When the power is turned on, all mechanisms begin to operate. The heating elements heat up rapidly, causing the upper and lower heating blocks to reach the desired temperature. The temperature control system adjusts the temperature to the required level. The stamping rollers rotate, and the cooling system activates as needed. The conveyor belt rotates, and the speed is adjusted to the required speed by the speed regulating device.
When a package containing goods is placed on the conveyor belt, the sealing portion of the bag is automatically fed between the two rotating sealing belts and carried into the heating zone. The heat from the heating blocks is transferred to the sealing portion of the bag through the sealing belts, softening the film. The film then passes through the cooling zone, where its surface temperature is appropriately reduced. Afterward, it is rolled by the knurling rollers (or printing rollers), which adhere the upper and lower plastic films of the sealing portion and press out a mesh pattern (or printed markings). Finally, the sealed bag is conveyed out of the machine by the guide rubber belt and the conveyor belt, completing the sealing operation.
A sealing machine is a mechanical device used to seal packaging containers. It is primarily used for product preservation and to prevent loss of contents. Suitable for containers made of paper, plastic, glass, metal, and other materials, it is widely used in the food, pharmaceutical, chemical, and cosmetic industries.
