Sealing machine classification

Sealing machine classification

Generally, according to the mechanical properties of packaging materials, it can be divided into the following two categories:

Flexible container sealing

Flexible containers are bag containers made of flexible materials such as paper, plastic films and composite films. The sealing of such containers is more and more


Bags and fillings form a combined machine and are rarely used independently. Due to different materials, the sealing device is different.

①Paper bag sealing device: For paper materials, generally apply adhesive to the sealing part, and then apply mechanical pressure to seal.

②Plastic film bag and composite material film bag sealing device: Plastic bags or composite bags made of good thermoplastics are generally directly heated at the sealing place and mechanical pressure is applied to fuse the sealing.

③ Cup sealing device. For example: common soy milk cups, milk tea cups, etc .. The cup edge and the film are bonded by heating to seal the container.

Automatic filling and sealing machine

It is mainly used for the filling of plastic cups, plastic boxes and plastic bottles, and the production of composite film sealing products of corresponding materials. If frozen, juice, milk, yogurt, beverages, fast food and other materials are filled and sealed. It can be adapted to the filling of liquids and slurries of different viscosities, and can be adapted to packaging containers of different shapes and capacities.


① Screw cap sealing machine: The finished cap of this sealing machine is processed with internal thread in advance, and the thread is divided into single head and multiple heads. Multi-threads are used for medicine bottles and multi-threads for canned bottles. The machine relies on rotating the lid and presses it tightly against the mouth of the container.

②Roll pattern sealing machine: The finished cap of this type of sealing machine is mostly made of aluminum. There is no thread in advance. The aluminum cap is rolled with a roller to make the cap have the same thread shape as the thread of the bottle mouth to seal the container. When the cover is unsealed, the indentation along the periphery of the skirt is disconnected and cannot be restored, so it is also called "anti-theft cover". This machine is mostly used for sealing packaging of high-grade alcohol and beverages.

③Flanging and sealing machine: It first puts the cylindrical metal cap on the mouth of the bottle and rolls its bottom edge with a roller to deform it inward, tightly holding the flange of the bottle and sealing it. This machine is mostly used for sealing packaging of wide-mouth canned bottles.

④Gland sealing machine: It is a crown sealing machine specially used for beer, soft drinks and other beverages. Place the crown cap on the mouth of the bottle, the capping mold of the machine presses down, the corrugated periphery of the crown cap is squeezed and retracted, and is caught on the flange of the neck of the bottle mouth, resulting in a mechanical connection between the bottle cap and the bottle mouth This seals the bottle.

⑤ Stopper sealing machine: This sealing material is made of rubber, plastic, cork and other materials with a certain elasticity, and uses its own elastic deformation to seal the bottle mouth. When the machine is sealing, the bottle stopper is placed above the bottle opening, and the bottle stopper is pressed into the bottle opening by the vertical pressure of the bottle stopper to achieve the sealing packaging. The stopper seal can be used either as a separate seal or as a combined seal with the bottle cap.

⑥Crimping sealing machine: This machine is mainly used for sealing metal food cans. It uses a roller to wrap the can lid and the periphery of the can body flange by crimping, hooking, and compressing each other to achieve sealed packaging.

⑦ Desktop automatic aluminum foil sealing machine. This machine is mainly used in medicine, pesticide, food, cosmetics, lubricating oil and other industries. It is an ideal sealing device, and the sealing speed is fast, all stainless steel mold forming shell, easy to use, good sealing quality, continuous work and other characteristics, suitable for large Mass production, beautiful appearance.

⑧Hand-held aluminum foil sealing machine. The hand-held aluminum foil sealing machine is used for aluminum foil sealing operations of non-metallic packaging containers such as plastic glass in the pharmaceutical, chemical, food, beverage, cosmetics, lubricants and other industries. The machine uses the principle of electromagnetic field induction heating, which uses a high-frequency current to generate a magnetic field through the inductive coil. When the magnetic field lines pass through the sealing aluminum foil material, a large number of small eddy currents are generated instantly, causing the aluminum foil to heat itself at high speed, melting the sol compounded on the aluminum foil It is pasted on the seal of the sealant to achieve the purpose of rapid sealing.

⑨ Pneumatic vertical sealing machine. The pneumatic vertical sealing machine adopts the vertical sealing method, which improves the operator's working efficiency and the flatness of the sealing, and can reduce the labor intensity for overweight items. The machine has reasonable structure, stable quality and reliable performance. It can be operated manually and pedal-operated electrically. It is simple, convenient, efficient and practical. It is widely used in chemical, food, food, feed and other industries.

⑩ Electromagnetic induction sealing machine. The electromagnetic induction sealing machine uses the principle of electromagnetic induction to instantly generate high heat on the aluminum foil on the bottle mouth, and then fuse on the bottle mouth to achieve the function of sealing. The sealing speed is fast, which is suitable for the production of large quantities of products; the all-stainless steel mold forming shell is beautiful and generous; easy to use, and the sealing quality is good. continuously working. It is an ideal sealing equipment for industries such as medicine, pesticides, food, cosmetics, and lubricants.

According to the application of materials, it can be divided into the following common categories

Plastic bag sealing machine, milk tea sealing machine, vacuum sealing machine, plastic cup sealing machine, jelly filling sealing machine, juice beverage filling sealing machine, instant noodle sealing machine, eight treasure porridge filling sealing machine, coffee filling sealing machine, sand ice cream Filling and sealing machine, duck blood filling and sealing machine, nitrogen sealing machine, side dishes vacuum sealing machine, chili sauce sealing machine, tomato sauce sealing machine, fast food box sealing machine, wide mouth bottle sealing machine, mineral water beverage filling and spinning Capping machine, yogurt bottle filling machine, etc.
