What are the classifications and applications of filling and packaging machinery?

Filling and packaging equipment refers to the mechanical equipment that fills liquid raw materials into packaging containers in predetermined quantities. It can be fluidized at a certain rate by its own net weight, and filled with high-viscosity raw materials, and can also be fluidized at a certain rate by working pressure, and filled with some viscous or semi-liquid materials. This filling machine is suitable for liquid filling of three kinds of packaging containers, such as plastic bottles, glass bottles and metal drums (including aluminum two-piece cans and tin cans), and is widely used in manufacturing.

Classification of filling and packaging equipment:

Filling machinery and equipment have various forms and classification methods due to differences in packaging containers, packaging products and filling processing techniques. More broadly; generally:

Classified by metrological verification method: liquid level meter volume filling machine, quantitative analysis filling machine, weighing filling machine;

Classification by filling method: atmospheric pressure filling machine, negative pressure filling machine, adiabatic process filling machine, working pressure filling machine;

Classified by packaging equipment: linear filling machine, disc filling machine.

exist:

1. Atmospheric pressure filling machine

Equipment for packing liquid raw materials into packaging containers under normal pressure. It is only suitable for filling liquid raw materials with high viscosity and no vapor, such as milk, soy sauce, daily chemical equipment, etc. It can be applied to packaging containers of various materials, such as glass bottles, plastic bottles, metal barrels, packaging bags, metal material barrels, etc. Quantitative analysis of volume, force filling. Atmospheric filling requires only one unsealed reservoir. For atmospheric filling machines that do not touch the utensils and filling valves, weighing-type filling machines with electronic devices can be used; for atmospheric filling machines where the utensils and filling valves are in contact and sealed, the filling machines often use materials Filling machine for quantitative analysis such as level device filling machine, organic waste gas manipulation liquid level meter or quantitative analysis cup, piston rod, etc.

Two, negative pressure and other liquid level meter filling machine

The negative pressure filling machine refers to the equipment that first sucks the indoor air into the packaging container to generate negative pressure, and then fills the liquid into the packaging container. According to the different filling methods, the negative pressure filling machine is divided into a gas pressure negative pressure filling machine and a force negative pressure filling machine.

The vacuum value adjustment during negative pressure filling should be moderate. Because the vacuum value is too high, the plastic flexible packaging (such as plastic bottles) will be deformed; if the vacuum value is too low, the liquid and bubbles in the filling valve and the exhaust pipe wall will not be affected. Can be sucked back, causing liquid to drip. The negative pressure filling machine has a faster filling speed, which can reduce the understanding and efficacy of liquid raw materials and residual gas in the vessel, and is beneficial to increase the shelf life of some liquid commodities. Beverages, fertilizers and chemicals.

3. Adiabatic process filling machine

The isobaric filling machine refers to the equipment that first inflates the packaging container so that the air pressure inside is the same as the air pressure in the liquid storage tank, and then fills the liquid into the packaging container.

4. Working pressure filling machine

The most common working pressure filling method is to pressurize the product, and the overflow tank communicates with the air. The equipment does not need bottle holders, chooses card bottles for filling, and does not need liquid storage tanks, but is equipped with a regulator on the filling wheel, one end of the distributor is connected to the centrifugal water pump installed in the liquid storage tank, and the other end is connected to Connect plastic hoses to each filling valve on the centrifugal water pump in the tank. The filling wheel is equipped with a ring-shaped precision positioning ring, and the positioning ring is punched with the same arc-shaped precision positioning groove as the total number of filling valves, and the axis of the positioning groove overlaps with the axis of the gate valve. When the PET bottle is transferred to the filling roulette, the water bottle holder enters the arc-shaped precise positioning groove from the head and neck of the roulette, and hangs on the annular precise positioning ring of the filling roulette. At this time, the core of the cork overlaps with the center of the filling valve. .The filling valve is lowered along the cam shaft with the rotation of the filling wheel, and the mouth of the filling vessel is sealed, which then promotes the gradual leakage of the filling valve.

The filling machine can be used in conjunction with different capping machines.
