Plate sealer

Plate sealer is a machine that seals the container filled with packing materials. After the product is put into the packaging container, it is necessary to seal the packaging container in order to keep the product sealed, maintain the product quality and avoid the loss of the product. This operation is done on the sealer. General sealing machine consists of frame, speed-reducing transmission mechanism, sealing and printing mechanism, conveying device and electrical and electronic control system. When the power supply 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 by the temperature control system. The impression wheel rotates, and the cooling system starts to cool as required. The conveyor belt turns and is adjusted to the required speed by the speed control device. When the package filled with articles is placed on the conveyor belt, the sealing part of the bag is automatically sent between two sealing belts in operation and brought into the heating zone. The heat of the heating block is transmitted to the sealing part of the bag through the sealing belt, so that the film is melted by heat, and then the surface temperature of the film is appropriately reduced through the cooling zone. Then, the plastic film on the upper and lower parts of the sealing part is bonded by a roller Hua Lun (or a printing wheel) and pressed into a net pattern (or printed logo), and then sealed by a guide rubber belt and the conveyor belt.
