An automatic screw capping machine is generally contained in the second stage of the liquid bottle filling production line. After the raw materials and bottles enter the production line, they go through a series of production activities. The process includes bottle filing, bottle screw capping or press capping, bottle top side labeling, and bottle front and back labeling. The production process is very flexible. And you can add or reduce the production procedure to meet your needs. Shanghai NPACK is a company specializing in the production of liquid bottle filling lines for efficient production of filling lines.
What is an Automatic Screw Capping Machine?
The automatic screw capping machine was initially created to lower the expense of the manual screw cap. The complete system framework of an automatic screw capping machine comprises a conveyor system, a bottle alignment system, a screw cap mechanism, and a control unit. It can serve not just in the filling line but also as an individual screw capping machine. The automatic screw capping machine’s conveying system includes linear conveying systems and rotary conveying systems. Compared with these two conveying methods, the linear conveying system is more cost-effective. Meanwhile, the linear conveying system can also accommodate different types of bottles.
The screw cap device is mainly controlled by the screw cap system. It can screw the cap through the program control to move the cap to the bottlemouth position. Then the bottle cap can be rotated into the bottlemouth by a two-wheel, three-wheel, or four-wheel screw capping machine. Shanghai NPACK’s automatic screw caping machines can be changed for different types of caps to suit the customer’s product requirements.
How does an Automatic Screw Capping Machine work?
1. After the filling process is completed, the screw capping process will begin. The bottle will go into the capping station through the conveyor belt. Next the bottle cap is transported by the bottle cap lifting machine.
2. Bottle cap lifting machine: There is usually a station for automatic screw capping. The required bottle caps are poured into the bottle cap lifting machine before capping. The bottle cap lifting machine will convey the bottle caps one by one. When it is conveyed to the top of the conveyor, the bottle caps will be automatically sucked into the pipeline.
3. Capping devices: Generally, in-line and rotary capping devices can be selected according to your needs. You can also choose how many capping heads you need.
4. Bottle positioner and sensor: When the bottle reaches the capping position, it will automatically position, and the sensor will sense whether there is a bottle in time. Capping is done with bottles and not without bottles, which results in higher accuracy and reduced errors.
5. Capping device: It can be adjusted according to different needs. The capping force and angle can be adjusted to suit different types of bottles and caps.
6. Capping head: When the bottle is capped, the screw capping head will screw and cap the bottle mouth. Once the bottle screw capping is completed, the motor will stop running. Next the bottle with cap will enter the labeling process.
What types of bottles and caps are compatible with the machine?
Generally speaking, the automatic screw capping machine is suitable for all types of bottles. Automatic screw capping machines are actually designed to simulate manual capping action. It utilizes the principle of ergonomics.
The most common type of capping machine is the rotary cap. These rotary caps generally have a spiral groove on the inside of the cap, which can be opened and sealed by rotating. This type of rotary bottle cap also has certain benefits, such as being reusable. When we drink beverages or other bottled or canned products, we can re-tighten the cap if we don’t finish it to prevent air from entering and oxidizing.
Currently, on the market, the more common plastic type of screw cap has a single piece of the cap and a double piece of the cap. Single-piece caps generally do not have a gasket inside and rely on the folded edge or the inner plug for sealing. Double-piece caps have a gasket inside, which is a softer material. When the start of the seal can rely on the compression of the gasket, rebound force to seal. In addition to plastic anti-theft caps, it can also be seen in the aluminum cap, which is generally made of pure aluminum and very light in weight. The cost is also relatively low. There is also an ordinary spiked cap for condiments and ketchup, which is great for everyday use. Thanks to the pressure, they come out by squeezing them directly, and they don’t get our hands dirty.
Regarding the types of bottles we see daily, plastic bottles are still the majority. Our daily lives can’t be separated from all types of bottles. Many bottles can store drink water and food. Besides the most common plastic bottles, there are also glass bottles with screw caps, metal bottles, ceramic bottles, and paper bottles for short-term food storage.
What industries commonly use Automatic Screw Capping Machines?
Food and Beverage Industry
Automatic screw capping machines occupy a large part of the food and beverage industry market. It is a show in the progress of technology and the arrival of Industry 4.0. As the largest consumer of automatic screw capping machines, more and more automatic screw capping machines can be put into production. It will greatly improve production efficiency and production quality.
The scope of application of automatic screw capping machines is also relatively broad.
- Drinking water
- Carbonated beverages
- Fruit juices
- Sauces and condiments
- Dairy products
Automatic screw capping machines seal to a certain extent and significantly improve the freshness of the product. Whether in transportation or secondary consumption, it will be safe and not leak. It is more efficient and less error-prone than manual capping, which is very popular.
Pharmaceutical Industry
Pharmaceutical industry capping requirements will be relatively higher. Drug encapsulation and sealing must be good to prevent drug contamination. The sealing process must be aseptic throughout so that the drug can be used to its maximum effect.
Cosmetics and Personal Care Industry
Most of the cosmetics and care products are used in the screw cap method and also in the screw cap process to ensure the degree of sealing to prevent contamination. Creams, lotions, essences and more rely on automatic screw capping machines to improve efficiency.
Chemical Industry
The chemical industry uses many dangerous chemicals and corrosive liquids, and the danger of human operation is relatively high. Automated machines are also better at protecting personnel’s safety. Higher precision also prevents leaks and allows products to be handled correctly.
