Features For Vacuum Capping Machine

Vacuum Quality
In order to ensure the vacuum quality of the vacuum capping machine, it is necessary to control the following aspects:
Vacuum pump selection and quality: select the appropriate type and quality of vacuum pump to ensure that it has sufficient pumping speed and vacuum degree.
The tightness of the vacuum pipeline: the vacuum pipeline needs to have a good sealing performance to avoid gas leakage, which will affect the vacuum degree and the effect of vacuuming.
The quality of the vacuum tank: The vacuum tank needs to have sufficient volume and pressure resistance to ensure that it can withstand the pressure inside the bottle in a vacuum state.
Operator skills: Operators need to be proficient in the operation skills of the vacuum capping machine to avoid insufficient vacuum caused by operational errors.
Inspection and testing: Regularly inspect and test vacuum pumps, vacuum tanks, pipelines, etc. to ensure that the equipment operates normally and the vacuum degree meets the requirements. At the same time, a quality inspection is carried out on the bottle after vacuuming to ensure product quality and stability.
Vacuum Principle
The principal vacuum part of the vacuum capping machine mainly includes a vacuum pump, a vacuum pipeline, and a vacuum tank. Its workflow is as follows:
The vacuum pump works to draw out the air inside the bottle to form a certain degree of the vacuum state. The extracted air is sent to the vacuum tank through the vacuum pipeline so that the pressure in the vacuum tank is gradually reduced. When the pressure in the vacuum tank drops to a certain value, the vacuum pump will stop working. In the vacuum state, the capping machine will automatically screw the cap into the bottle mouth, and at the same time tightly seal the bottle mouth to ensure that the oxygen content in the bottle is reduced and the shelf life of the product is extended.
The vacuum part of the vacuum capping machine uses a vacuum pump to extract the air in the bottle, reducing the pressure in the bottle to a certain level, forming a vacuum state, and then capping. This ensures that the oxygen content in the bottle is reduced, extending the shelf life of the product while also ensuring product quality and stability.


Vacuum Pump
The vacuum pump on the vacuum capping machine is an important part responsible for extracting the gas in the bottle and forming a certain degree of the vacuum state. Common types of vacuum pumps include rotary vane pumps, gear pumps, Roots pumps, etc.
The rotary vane pump is the most common type of vacuum pump and works by drawing gas through the space between the rotating vanes and the pump casing. The pump has the advantages of fast pumping speed, good stability, and simple maintenance, so it is widely used in vacuum capping machines.
The gear pump pumps gas through the mutual meshing of two gears. It has the advantages of small size and fast pumping speed and is suitable for small vacuum equipment.
The Roots pump pumps gas through two mutually rotating impellers. It has the advantages of fast pumping speed and simple maintenance, but the cost is relatively high, and it is suitable for high-precision and high-demand vacuum equipment.

The vacuum pressure required by the vacuum capping machine is usually between -0.08 MPa and -0.095 MPa. This range is an ideal vacuum pressure, which can ensure that the air in the bottle is fully removed during the capping process, thereby ensuring the quality and shelf life of the product. However, the specifically required vacuum pressure will also be affected by the nature of the product itself and the type of bottle, and different products and bottles may require different vacuum pressures. In practical applications, it needs to be adjusted and optimized according to the actual situation.
The vacuum capping machine is suitable for various types of containers, such as glass bottles, plastic bottles, metal bottles, etc. Different containers have different shapes and sizes, but as long as they meet certain requirements, they can all be operated on the vacuum capping machine. Typically, the bottle needs to have a certain degree of rigidity and stability to ensure that it does not deform or collapse during the capping process. In addition, it is necessary to ensure that the size and shape of the bottle are suitable for the clamp of the machine to ensure stability and tightness. In actual application, it needs to be adjusted and optimized according to different bottle types to ensure the success of the operation and the quality of the effect.
Cleanliness and sanitation: The production workshop needs to maintain a good clean and hygienic environment, especially in the area around the vacuum capping machine, to prevent dust, pollutants, etc. from entering the machine, affecting the effect of operation and the quality of products.
Ventilation conditions: Since the vacuum capping machine needs to be vacuumed, the production workshop needs to have good ventilation conditions to ensure indoor air circulation when the machine is in operation and to discharge the exhaust gas generated in the exhaust pipe.
Energy and electricity: The vacuum capping machine needs to be connected to the power supply and compressed air supply system, and the production workshop needs to have stable and reliable electricity and air supply to ensure the normal operation of the machine.
Space and layout: The vacuum capping machine requires a certain operating space and layout arrangement to facilitate the operation and maintenance of the operator. Sufficient space needs to be allowed in the workshop to ensure that operators can move freely and easily enter and exit the area around the machine.
Operators: The operation of the vacuum capping machine requires professional technicians, and the production workshop needs to have corresponding talents and technical support to ensure the normal operation of the machine and the effect of the operation.
