Bottle packaging is very common and applied in the food and beverage industry, pharmaceutical industry, and daily chemical industry. The tightness of bottle packaging is very important as the products are needed to be stored well before consumers opening. Poorly sealed packaging can lead to leakage and pollution, product rot, and harm to the human body health. The coordination of the bottle cap and the bottle mouth, the structural design is an important condition to ensure the tightness.

What Should Be Paid Attention to During Cap Sealing?

1. Requirements for bottle mouth and bottle cap: The bottle cap is connected to the bottle mouth, and the bottle cap is firmly fixed on the bottle mouth. It is also very convenient to open and close the cap by unscrewing or other methods.

2. Some bottle caps have no lining structure, and their caps should have the characteristics of smoothness and uniformity at the sealing part in contact with the bottle mouth.

The inner seal, outer seal, and top seal of the bottle cap provide sealing capabilities. The bottle mouth and the sealing area produce a certain amount of deformation, and the constant amount of deformation exerts a certain force on the bottle mouth to achieve the sealing effect.

What Main Materials Will Be Used for Pharmaceutical Bottle Caps?

Most of the medicinal bottle caps are in direct contact with the drugs, so the medicinal bottle caps generally have the characteristics of barrier, moisture prevention, and pollution prevention. They must play an important role in preventing the escape of drugs in the bottle and preventing any foreign matter from entering the bottle. The integrated bottle cap uses plastic material as the main raw material.

Most of the pharmaceutical bottle caps use PE and PP as the main raw materials, and the common screw caps are commonly used. The screw caps achieve the function of sealing by matching the threads in the caps with the mouth of the bottle.

What Are the Applications of Capping Machines?

High-speed capping machine is mainly used in the pharmaceutical, industrial, chemical, and food industries. It is a special equipment for automatic capping of plastic bottles and glass bottles. Through automatic bottle feeding, automatic cap sorting, automatic cap ejection, automatic cap pressing, automatic cap screwing, automatic bottle ejection and other processes. It greatly improves labor productivity and avoids the artificial pollution caused by manual screwing in the past.

The Principle of Capping Machine

The bottle cap manager is arranged by the cap mechanism, and the mouth-up bottle caps are continuously sent to the cap drop track. The bottles will be transported from the other equipment of the assembly line to the bottle delivery track enter the cap drop area, and the bottles are clamped by the bottle clamping devices on both sides. The bottle cap is automatically put on when moving forward. The capping device presses the bottle cap to a pre-tightened state before screwing the cap. Under the action of three pairs of high-speed rotating wear-resistant rubber wheels, the bottle cap is tightly screwed on the bottle body.

Automatic capping machine is easy to operate, and the capping speed is accurate and fast. High speed capping machine can manually place the filled bottles on the conveyor belt, and the conveyor belt will automatically send the placed bottles to the capping mechanism to complete the capping accurately and quickly . It can also be used in connection with other machines. Taking pill counting as an example, a fully automatic filling and counting production line can be used. The granulator uses photoelectric counting to accurately count the granules into the bottle, and finally transport to the capping machine to complete the capping. The whole capsule counting line is fully automated, saving labor and high productivity.
