The tube filling and sealing machine
presses the start button during the operation, the transfer wheel and the filling machine are started, and then the conveyor start button is pressed, and the filling conveyor of the filling machine is started. After the bottles enter the conveyor belt, the bottles are equally spaced into the bottle tray lifting mechanism by passing the wheels. When the pallet detects the pressure, the tray piston presses the tray lift mechanism and the tray begins to rise with the bottle. During the rise time of the tray, the larger rise time is 6S. If the pressure is detected in the centering of the liquid inlet, the tray stops rising, and then the gas valve opens to start filling the bottle with CO2. The larger inflation time is 6S.
Filling and sealing machine when detecting defective products
tube filling and sealing machine
1. When the defective product is a burst bottle
In the normal filling process, when the larger tray time rises by 6S, the pressure is not detected in the centering of the filling nozzle (the bottle is bursting, the height is insufficient), then the tray starts to fall, and the defective product light is on, and the tray is lowered. Time 6S. The tray is lowered and waiting to enter the next cycle. At the same time, the defective detector is activated.
2. When the defective product is broken
After the normal filling process, when the large inflation time is 6S, the air valve does not detect the air pressure (broken bottle, CO2 is not full), then the CO2 is stopped, and the bottle tray starts to fall, the defective product light is on, and the tray falling time is 6S, the tray is lowered to wait for the next cycle, and the defective detector is started.
This machine is mainly composed of fluid conveying (ie feeding system), container conveying (ie bottle feeding system), filling valve, large turntable, transmission system, body, automatic control and so on.
Filling method of filling and sealing machine
1) Normal pressure method
The atmospheric pressure method is also called the pure gravity method, that is, under normal pressure, the liquid material flows into the packaging container by its own weight. Most free-flowing, non-liquid-liquid materials can be filled by this method, such as white wine, fruit wine, milk, soy sauce, vinegar, etc.
2) Isobaric method
The isostatic method is also called pressure gravity filling method, that is, under the condition of above atmospheric pressure, the packaging container is first inflated to form an air pressure equal to that in the liquid storage tank, and then the self-weight of the liquid to be poured is flown in. Inside the packaging container. This method is commonly used for the filling of carbonated beverages such as beer, soda, sparkling wine, and the like. Filling with this method can reduce the loss of CO2 contained in such products, and can prevent excessive foaming during the filling process and affect product quality and quantitative accuracy.
3) Vacuum method
The vacuum method is filled at sub-atmospheric pressure and can be carried out in two ways.
a) Differential pressure vacuum
That is, the liquid storage tank is at normal pressure, and only the packaging container is evacuated to form a vacuum, and the liquid material is flowed to complete the filling by the pressure difference between the liquid storage tank and the container to be filled. This method is commonly used in China.
b) gravity vacuum
That is, the liquid in the liquid storage tank is in a vacuum, and the packaging container firstly draws air to form a vacuum equal to that in the liquid storage tank, and then the liquid material flows into the packaging container by its own weight. Due to the complicated structure, it is less used in China. The vacuum filling method is widely used, and it is suitable for filling liquid materials with a slightly higher viscosity, such as oils and syrups. It is also suitable for filling liquid materials containing vitamins, such as vegetable juice, fruit juice, etc. The formation of vacuum in the bottle means that the contact between the liquid material and the air is reduced, and the shelf life of the product is prolonged. The vacuum method is also suitable for filling the toxic materials. Such as pesticides, etc., to reduce the spillover of toxic gases and improve working conditions.
