Share the working principle of the hot melt sealing machine

Hot-melt sealing machine is a hot-melt plastic bottle and cap sealing equipment, which is widely used in the sealing of plastic bottles such as glucose, antibiotics, fat emulsion, oral liquid, nutrient solution, and biological preparations.

The hot melt sealing machine is a machine that seals the container filled with packaging. After the product is put into the packaging container, in order to keep the product sealed, keep the product quality, and avoid product loss, the packaging container needs to be sealed. This operation is done on a sealer.

Generally, the sealing machine is composed of a frame, a deceleration and speed-regulating transmission mechanism, a sealing and printing mechanism, a conveying device and an electrical and electronic control system.

The following editor will briefly introduce the working principle of the hot melt sealing machine to you, as shown below: When the power is turned on, each mechanism starts to work.

When the temperature is required, the imprinting wheel rotates, and the cooling system starts to cool according to the needs, and the conveyor belt is rotated and adjusted to the required speed by the speed regulating device.

When the package containing the articles is placed on the conveyor belt, the sealing part of the bag is automatically sent between the two sealing belts in operation and brought into the heating zone, and 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 and softened, and then passed through the cooling zone to make the surface temperature of the film drop appropriately, and then 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.
