A capping machine is a device used for sealing containers by securely fastening caps onto them, ensuring the integrity of the liquid or other products inside. The design principle of the capping machine involves a combination of rotation and pressure, using capping wheels or heads to apply rotational force to the cap, tightening it evenly onto the container. Linear capping machines operate with a linear motion to handle the caps, while automatic rotary capping machines use a rotating disk to automatically position the bottles and caps, enabling fast and accurate sealing. During operation, the machine adjusts the speed and pressure of the capping process according to set parameters and control systems, accommodating various bottle sizes and types. Capping machines are widely used in the food, beverage, pharmaceutical, and cosmetic industries, especially for high-volume production lines, offering an efficient and stable capping solution.
