Capping machine is a kind of mechanical equipment for sealing bottle caps, which is mainly used in the production of food, beverage, pharmaceutical and other industries. Its working principle mainly includes the following steps:

Firstly, conveying bottles. At the beginning of the work, the bottle caps to be sealed need to be conveyed to the working position of the capping machine. Usually, the bottles are transported to the capping machine by conveyor belts and other transport equipment.

The second step is to position the bottles. Once the bottle reaches the working position of the capping machine, the sensors detect the presence of the bottle and position it in the appropriate position on the capping machine. This step is designed to ensure that the bottles will accurately receive the sealing operation of the capper.

The third step is the capping action. Once the bottle is properly positioned, the capping head of the capping machine will begin to rotate, placing the cap on the bottle opening. Subsequently, the capping head will apply appropriate pressure to tighten the cap and complete the sealing operation.

The fourth step is to output the finished product. The bottles after sealing will be sent out of the capping machine in turn, and when the whole sealing process is completed, the finished bottles will be ready for the next production process. At the same time, the capping machine will continue to accept new bottles, the cycle of sealing operations.

Overall, the capping machine completes the operation of sealing bottle caps through four steps: conveying, positioning, capping action and outputting finished products. Its working principle is simple and efficient, and it is one of the indispensable and important equipments in modern industrial production.
