Operation principle and trouble shooting of electromagnetic induction sealing machine for aluminum foil

Electromagnetic induction aluminum foil sealing machine is widely used for sealing containers of medicine, liquid medicine, perfume, detergent, milk, beverage, food, chemical products, etc it plays the role of sealing, anti-counterfeiting and anti-theft This machine has reasonable design, reliable performance, convenient operation, high production efficiency, small area, light weight, low noise and small consumption It is widely used in medicine, food, oil, daily chemical, pesticide and other industries The equipment uses the principle of electromagnetic induction to produce high temperature at the moment of the aluminum foil on the bottle mouth, and then fuse the aluminum foil on the bottle mouth to achieve the sealing function It has good moisture-proof, mildew proof and anti-counterfeiting functions, thus prolonging the storage time of articles Features of sealing machine: high speed sealing, used with assembly line, suitable for production (sealing) of assembly line mass products; Two sets of movement (main board) and two sets of power amplifiers in the machine can output high-power current to meet high-speed sealing; the equipment is equipped with automatic bottle feeding device, which is more convenient for high-speed production; it can be equipped with automatic aluminum foil free bottle removal device and automatic bottle sealing counter; the sealing efficiency is high (0-200 bottles / min), and the sealing quality is good; the equipment is automatically started and stopped, continuously working, and easy to operate; all stainless steel mold forming The shell is beautiful and generous, and the equipment works stably and reliably; it is non-contact heating, suitable for the sealing of various plastic bottles and composite plastic bottle mouths, meeting GMP standards; the materials of sealed containers can be polypropylene (PP), polystyrene (PS), polyester (PET), polyethylene (PE), ABS and glass, etc (the company also provides induction aluminum foil film of various materials)     We all know that the packaging machinery has been used for a long time, especially in the case of continuous work and overload, it is easy to have some electrical and mechanical faults, such as the sealing machine: the sealing is not firm, the machine goes and stops, the fuse blows at the start, the "squeak" occurs during operation, the temperature cannot be controlled, the finished product bag at the sealing is deformed and bent, the air bubble or air bubble appears at the sealing knife's imprint Irregular marks, etc Next, I will introduce how to deal with some common problems Let's take a look 1 The sealing is not firm The sealing failure is one of the common failures of the continuous sealing machine, which has three meanings: ① the sealing part of the packaging bag cannot be sealed; ② under the pressure of the sealing knife, although the opening of the bag is sealed, the sealing will crack again if the bag is slightly squeezed or torn; ③ when the sealing part is peeled, half of the sealing is firm and half of the sealing is separated, so the sealing quality of the packaging bag is still not good Lattice, because the contents are easy to be missed during the storage and transportation This situation often occurs when the composite lining is OPP and blow molded PE The main causes of * kinds of faults are as follows (1) Insufficient heat sealing temperature: in general, when the total thickness of the compound bag made of OPP is 80-90 μ m, the heat sealing temperature should reach 170-180 ℃; when the total thickness of the compound bag made of PE is 85-100 μ m, the temperature should be controlled at 180-200 ℃ As long as the total thickness of the bag is increased, the heat sealing temperature must be increased accordingly (2) Hot sealing speed is too fast: the sealing failure is also related to the speed of sealing machine If the speed is too fast, and the sealing part is not heated yet, it will be sent to the cold pressing part by the traction roller for cooling treatment, which naturally fails to meet the quality requirements of the heat sealing (3) Improper pressure of cold pressing rubber wheel: there is one above and one below the cold pressing rubber wheel, and the pressure between them should be moderate Only clamp the spring when adjusting the pressure Well, the above is all about the operation principle and troubleshooting of the electromagnetic induction aluminum foil sealing machine I hope it can help you.
