The sealing machine is a machine that seals the container filled with the packaging material. After the product is packed into the packaging container, in order to keep the product sealed, maintain the quality of the product, and avoid product loss, the packaging container needs to be sealed. Finished on the sealing machine.
A sealing machine is a machine that seals a container after it is filled with a product. There are many materials for making packaging containers, such as paper, plastic, glass, ceramics, metal, composite materials, etc. The shapes 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 seal Flexible containers are bag containers made of flexible materials such as paper, plastic films, and composite films. The sealing of this type of container is mostly combined with bag making and filling, which is rarely used independently. Due to different materials, the sealing device is also different. ① Paper bag sealing device: For paper materials, generally apply adhesive to the sealing place, and then apply mechanical pressure to seal. ② Plastic film bag and composite material film bag sealing device: Plastic bags or composite bags made of good thermoplastics are generally heated directly at the seal and applied mechanical pressure to fuse the seal. ③ Mouth cup container sealing device. For example: common soy milk cups, milk tea cups, etc. By heating the cup edge and the film to make the container sealed.
Automatic Filling and Sealing Machine It is mainly used for the production of plastic cups, plastic boxes and plastic bottles as fillers and composite film sealing products of corresponding materials. If frozen, fruit juice, milk, yoghurt, beverages, fast food and other materials are filled and sealed. It can adapt to fillings of liquids and slurries of different viscosities, and can adapt to packaging containers of different shapes and capacities. kind ① Capping and sealing machine: The finished cap of this sealing machine is processed with internal threads in advance, and the threads are divided into single and multiple ends. Medicine bottles mostly use single-head threads, and canned bottles often use multiple-head threads. The machine relies on the rotary cap to compress it against the mouth of the container. ② Rolling Sealing Machine: The finished cap of this sealing machine is mostly made of aluminum, without any thread in advance. The aluminum cap is rolled with a roller to make the cap appear exactly the same thread shape as the bottle thread to 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 an “anti-theft cover”. This machine is mostly used for sealing packaging of high-grade alcoholic beverages. ③Squaring and sealing machine: It first puts the cylindrical metal cap on the bottle mouth, rolls the bottom edge with a roller, deforms it inwardly, and fastens the bottle mouth flange to seal it. This machine is mostly used for sealing and packaging of wide mouth canned bottles. ④ Gland Sealing Machine: It is a crown cover sealing machine specially used for beer, soda and other beverages. The crown cap is placed on the bottle mouth, and the gland die of the machine is pressed down, the corrugated periphery of the crown cap is squeezed and contracted, and it is stuck on the flange of the neck of the bottle mouth, which causes a mechanical hook between the bottle cap and the bottle mouth. This seals the bottle. ⑤Seal sealing machine: This sealing material is a stopper 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 mouth, and the bottle stopper is pressed into the bottle mouth by the vertical pressure of the bottle stopper to achieve sealing packaging. The stopper seal can be used as a separate seal or as a combined seal with a cap. ⑥Crimping and sealing machine: This machine is mainly used for sealing metal food cans. It uses a roller to curl the can lid and the periphery of the can body flange to each other by crimping, hooking, and pressing to achieve sealed packaging. ⑦Desktop 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 has a fast sealing speed. The housing is made of stainless steel mold. It is easy to use, has good sealing quality, and works continuously. Mass production, beautiful appearance. ⑧Hand-held aluminum foil sealing machine. This hand-held aluminum foil sealing machine is used for the aluminum foil sealing operation of non-metal packaging containers such as plastic glass in the pharmaceutical, chemical, food, beverage, cosmetics, lubricants and other industries. This machine adopts the principle of electromagnetic field induction heating. It uses high-frequency current to generate a magnetic field through the inductive coil. When the magnetic field lines pass through the sealed aluminum foil material, a large number of small eddy currents are generated instantaneously, causing the aluminum foil to heat itself at high speed and melt the sol compounded on the aluminum foil. It can be affixed to the sealing of the sealing material to achieve the purpose of rapid sealing. ⑨Pneumatic 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 has reasonable structure, stable quality, and reliable performance. It can be operated manually and can be pedal-operated. It is simple, convenient, efficient, and practical. It is widely used in chemical, food, food, feed and other industries. ⑩Electromagnetic 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 to the bottle mouth to achieve the sealing function. Fast sealing speed, suitable for mass production; full stainless steel mold shell, beautiful appearance; easy to use, good sealing quality. continuously working. It is an ideal sealing equipment for pharmaceutical, pesticide, food, cosmetics, lubricants and other industries.
