General structure of sealing machine

A general sealing machine is composed of components such as a frame, a deceleration and speed control transmission mechanism, a sealing and printing mechanism, a conveying device, and an electrical and electronic control system.

Connect the power supply, and each mechanism begins to work. After the electric heating element is energized, it heats up the upper and lower heating blocks rapidly, and is adjusted to the desired temperature through the temperature control system. The printing wheel rotates, and the cooling system starts to cool as needed. The conveyor belt rotates and is adjusted to the desired speed by the speed control device.

When the packaging containing items 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. The heat of the heating block is transmitted to the sealing part of the bag through the sealing belt, causing the film to melt and soften. Then, through the cooling zone, the surface temperature of the film is appropriately reduced. Then, through the rolling wheel (or printing wheel), the plastic film on the upper and lower parts of the sealing part is bonded and pressed to form a mesh pattern (or printed logo). Then, the sealed packaging bag is sent out of the machine by the guide rubber belt and the conveyor belt to complete the sealing operation.
