What are the types of cap assembly machines?

Sealing machine is the machine that seals the container after the packaging container is filled with products. There are many materials used to make packaging containers, such as paper, plastic, glass, ceramic, metal, composite materials, etc. The form and physical properties of the packaging containers vary, so do the forms of sealing and the sealing devices used. Today, there are more and more types of sealing machines. The range of applications in society is also getting wider and wider.

This passage is going to talk about the followings of the cap assembly machine:

1) Basic working principle of cap assembly machine

When the quantitative packaging scale into automatic operation, the weighing control system to open the feeding door to start feeding, the feeding device for fast, slow two-stage feeding mode; when the weight of the material reaches the fast feeding set value, stop fast feeding, keep slow feeding; when the weight of the material reaches the final set value, close the feeding door, complete the dynamic weighing process; at this time, the system detects whether the bag clamping device in the predetermined state, when the bag has been clamped When the bag has been clamped, the system will send a control signal to open the unloading door of the weighing hopper, the material will enter the bag, and the unloading door of the weighing hopper will be closed automatically when the material is finished. After the bag is dropped, the bag is sewn and transported to the next station. This cycle runs automatically.

2) What are the types of cap assembly machines?

①Screw cap sealing machine. This kind of capping prior processing of internal threads, threads have a single head or multi-head. For example, medicine bottles mostly use single-head thread, and cans mostly use multi-head thread. The machine is dependent on the rotation of the cap, and will be pressed in the mouth of the container.

②Rolling sealing machine. This kind of sealing cap is mostly made of aluminum and has no threads beforehand. The aluminum cap is rolled with a roller to make the threads appear exactly the same shape as the threads of the bottle mouth, and the container is sealed. This kind of cap will break the indentation along the skirt perimeter when opening and sealing, and cannot be recovered, so it is also called 'anti-theft cap'. This machine is mostly used for high-grade wine and beverage sealing and packaging.

③Rolling edge sealing machine. It is first set the barrel-shaped metal cap on the bottle mouth, roll the bottom edge with a roller, so that it turns inward and deformed, clasp the bottle mouth flange and seal it. This machine is mostly used for sealing and packaging of wide-mouth cans, etc.

④Capping and sealing machine. It is specially used for beer, soft drink and other beverage crown cap sealing machine. The crown cap is placed on the mouth of the bottle and the press cap die of this machine is pressed down, the corrugated periphery of the crown cap is squeezed inward and stuck on the flange of the neck of the bottle mouth, causing a mechanical hook-up between the cap and the bottle mouth, thus sealing the bottle.

⑤ Pressed stopper sealer. This kind of sealing material is made of rubber, plastic, cork and other materials with certain elasticity to seal the bottle mouth by using its own elastic deformation. When sealing, the cork is placed above the mouth of the bottle and pressed into the mouth of the bottle through the vertical pressure on the cork to achieve sealing. The cork seal can be used as a stand-alone seal or as a combination seal together with the bottle cap.

(6) Rolled edge sealing machine. This machine is mainly used for sealing metal food cans. It uses rollers to seal the perimeter of the lid and the flange of the can by curling, hooking and pressing each other to achieve sealing packaging.
