Classification by characteristics of packaging material

[aminaas1575]

Filling machines are diverse due to different packaging containers, packaging materials and filling processes, and there are many classification methods.

2.1 Classification by the main form of movement of packaging containers
2.1.1 Rotary filling machines

The container to be filled is sent to the filling machine by conveyor system or manually, and the container is driven by the rotary table of the filling machine to continuously fill. When the container turns almost one circle, it is filled, and then sent to the seaming machine by the rotary table for seaming, as shown in Figure 1.

This type of filling machine is most widely used in food and beverage industry, such as soda, juice, beer and milk filling. This machine is mainly composed of liquid feeding jamaica number data system (i.e. feeding system), container feeding system, filling valve, large rotary table, transmission system, machine body, automatic control and other parts. Among them, the filling valve is the key to ensure the normal operation of the filling machine.

2.1.2 Linear filling machine

The filling container moves in a straight line and is filled in rows. Each time a row of empty containers is sent, it is pushed forward by the rolling plate. When it is sent to the bottom of the filling pipe, the valve opens for filling, and the operation is carried out in intervals, as shown in Figure 2.

Compared with the rotary filling machine, this type of filling machine has a simpler structure and is easy to manufacture, but it occupies a large area and moves at intervals. The improvement of productivity is also subject to certain limitations. Therefore, it is generally used only for filling airless liquid materials, which has great limitations.
