Hot Filling Machine

The washing section of the filling machine responsible for washing bottles is a rotary bottle washing. It is primarily used for rinsing new bottles for beverages and drinking water. The main structure of the equipment that comes into contact with the rinsing medium and the external cover is made of stainless steel, including the stainless steel clamps. The machine has a simple structure that is easy to adjust, and the contact area with the bottle neck is minimal, reducing the risk of secondary pollution. Furthermore, the machine has a water collection tray to recycle the rinsing water.

The filling section is responsible for filling the material into the washed bottles provided by the bottle washing machine, using a pressure filling and negative pressure reflux method. This filling method is quick and responsive, and provides high precision filling. The filling valve has no spring, so the material does not come into contact with the spring and can be easily cleaned. To ensure the filling process and to address filling issues, the filling valve is designed to maintain a slight backflow of material when there is no bottle present or when the machine is stopped. The filling cylinder adopts a full-cylinder filling method to ensure the stability of pressure inside the cylinder.

The capping section is powered by a reduction gearbox which drives the turntable to rotate, causing the caps to be expelled from the hopper by the centrifugal force. A positive and negative cap separation device is situated at the outlet. If a negative cap is detected, it is automatically blown back into the hopper by an air current. Only positive caps can enter the chute and be conveyed to the cap feeding tray. The number of caps in the hopper is detected by photoelectric switches which control the cap conveyor and ensure that capping is performed effectively. To prevent accidents, an anti-reverse mechanism is installed on the chute, and a pair of photoelectric switches are positioned to stop the machine immediately if no cap is detected.
