what is the sealing machine Part 1

The sealing machine is the equipment that seals the container filled with a certain material. After putting the products into the packaging container, in order to keep the product sealed, maintain product quality, and avoid product loss, it is necessary to seal the packaging container. This operation is Finished on the sealing machine.
The sealing machine refers to the machine that seals the container after the packaging container is filled with the product. There are many materials used to make packaging containers, such as paper, plastic, glass, ceramics, metals, composite materials, etc. The shape and physical properties of packaging containers are also different.
Generally, according to the mechanical properties of packaging materials, it can be divided into the following two categories:
Flexible container closure
Sealer

Flexible containers are bag-like containers made of flexible materials, such as paper, plastic film, and composite film. The sealing of this type of container is mostly combined with bag making and filling, and it is rarely used independently. Due to different materials, the sealing device is also different.
¢ÙPaper bag sealing device: For paper materials, the adhesive is generally applied to the sealing part, and then mechanical pressure is applied to the sealing.
¢Ú Sealing device for plastic film bags and composite film bags: Plastic bags or composite bags made of good thermoplastics are generally directly heated at the seal and applied mechanical pressure to fuse the seal.
¢ÛCup type container sealing device. For example: common soy milk cups, milk tea cups, etc.. The rim of the cup 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. Filling and sealing of jelly, fruit juice, milk, yogurt, beverage, fast food and other materials. 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.
type
¢ÙCapping and sealing machine: The finished cap of this type of sealing machine is processed with internal threads in advance. The threads are divided into single-end and multi-end. Single-thread threads are mostly used for medicine bottles, and multiple threads are used for canned bottles. This machine relies on rotating the cap to compress it to the mouth of the container.
¢ÚKnurling sealing machine: The finished caps of this type of sealing machine are mostly made of aluminum without thread beforehand. The aluminum cap is rolled with a roller to make the cap appear with the same thread shape as the bottle mouth thread and seal the container. When the cover is unsealed, the indentation along the periphery of the skirt is broken, and cannot be restored, so it is also called "anti-theft cover". This machine is mostly used for sealing and packaging high-end wines and beverages.
¢ÛPiping sealing machine: It first puts the cylindrical metal cap on the bottle mouth, rolls the bottom edge with a roller to make it inverted and deformed, and tightly buckles the flange of the bottle mouth to seal it. This machine is mostly used for sealing and packaging wide-mouth cans and bottles.
¢Ü Capping sealing machine: It is a crown cap sealing machine specially used for beverages such as beer and soda. Put the crown cap on the bottle mouth, press the machine's capping mold, the corrugated periphery of the crown cap is squeezed and contracted, and it gets stuck on the flange of the neck of the bottle mouth, causing the mechanical hooking between the bottle cap and the bottle mouth. Thus, the bottle is sealed.
¢ÝPressing plug sealing machine: This kind of sealing material is a bottle stopper made of rubber, plastic, cork and other materials with 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 mouth, and the vertical pressure of the bottle stopper is pressed into the bottle mouth to realize the sealing and packaging. The plug seal can be used as a single seal or as a combined seal with the bottle cap.
¢ÞCrimping sealing machine: This machine is mainly used for sealing metal food cans. It uses rollers to crimp, hook and press the periphery of the can cover and the can body flange to achieve hermetic packaging.
¢ß Desktop automatic aluminum foil sealing machine. This machine is mainly used in medicine, pesticide, food, cosmetics, lubricating oil and other industries. It is the ideal sealing equipment, and the sealing speed is fast. Mass production, beautiful appearance.
¢àHand-held aluminum foil sealing machine. This hand-held aluminum foil sealing machine is used for the aluminum foil sealing operation of plastic glass and other non-metallic packaging containers in the pharmaceutical, chemical, food, beverage, cosmetics, lubricant and other industries. The machine adopts the principle of electromagnetic field induction heating. It uses high-frequency current to generate a magnetic field through the inductance coil. When the magnetic line of force passes through the sealing aluminum foil material, a large number of small eddy currents are instantly generated, causing the aluminum foil to heat up at high speed and melt the sol compounded on the aluminum foil. Paste on the seal of the sealing object to achieve the purpose of rapid sealing.
¢áPneumatic vertical sealing machine. The pneumatic vertical sealing machine adopts a vertical sealing method, which improves the working efficiency of the operator and the flatness of the sealing, and can reduce the labor intensity for overweight items. The machine is reasonable in structure, stable in quality, reliable in performance. It can be operated manually or electric by foot. It is simple, convenient, efficient and practical. It is widely used in chemical, grain, food, feed and other industries.
¢â 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 it on the bottle mouth to achieve the function of sealing. The sealing speed is fast, suitable for mass production; the all-stainless steel mold forms the shell, which is beautiful and generous; it is easy to use and the sealing quality is good. continuously working. It is an ideal sealing equipment for the industries of medicine, pesticide, food, cosmetics, lubricants and so on.
