Electromagnetic induction aluminum foil sealing machine is widely used for sealing of containers such as medicines, liquid medicines, spices, detergents, milk, beverages, food, chemical products, etc., and 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 low consumption. Widely used, mainly used in medicine, food, oil, daily chemical, pesticide and other industries.
????The device is based on the principle of electromagnetic induction. The aluminum foil on the bottle mouth instantly generates high temperature, and then the aluminum foil is fused on the bottle mouth to achieve the sealing function. It has good moisture-proof, mildew-proof, and anti-counterfeiting effects, thereby prolonging the storage time of items.
????Sealing machine features:
?????High-speed sealing, used with the assembly line, suitable for the production of large-scale products in the assembly line (sealing);
2 sets of movements (main board) and 2 sets of power amplifiers in the machine, which 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; optional automatic aluminum foil bottle rejection device can be automatically sealed Bottle counter; high sealing efficiency (0-200 bottles / minute), good sealing quality; automatic start and stop of the equipment, continuous work, easy operation; full stainless steel mold shell, beautiful and elegant, stable and reliable equipment work; non-contact heating, adapt The sealing of various plastic bottles and composite plastic bottles meets GMP standards; the materials of the sealed containers can be polypropylene (PP), polystyrene (PS), polyester (PET), polyethylene (PE), ABS and Glass, etc. (At the same time, the company also provides induction aluminum foil films of various materials).
????Everyone knows that the packaging machinery has been used for a long time, especially under continuous work and overload conditions, it is prone to some electrical and mechanical failures, such as the sealer: the seal is not strong, the machine stops and stops, the fuse blows when starting, 'Squeak' sounds during operation, the temperature cannot be controlled, the finished bag is deformed and bent at the seal, and bubbles or irregular marks appear at the seal imprint.
?????The following editors introduce how to deal with some common problems. Let's take a look.
1. The seal is not strong
Insufficient sealing is one of the common failures of continuous sealing machines. Insufficient sealing has three meanings: ① The sealing of the packaging bag cannot be sealed; ② Under the pressure of the sealing knife, the bag is sealed, but it is squeezed or squeezed slightly. After peeling, the seal will crack again. ③ When peeling test is performed on the seal, half of the seal is strong and half is separated. The quality of the seal of such a packaging bag is still unsatisfactory because the contents are extruded during storage and transportation. Easy to miss. This situation often occurs when the composite lining is OPP and blown PE.
The main causes of the * failures are as follows.
(1) Insufficient heat sealing temperature:
Under normal circumstances, when the total thickness of the bag made of OPP is 80 ～ 90μm, the heat-sealing temperature must reach 170 ～ 180 ℃; the total thickness of the bag made of PE as the lining is 85 ～ 100μm At this time, 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) Heat sealing speed is too fast:
Closing the mouth is also related to the speed of the sealing machine. If the speed is too fast, the seal can be heated in the future by the traction roller and sent to the cold press for cooling treatment, which naturally fails to meet the heat seal quality requirements.
(3) The pressure of the cold-pressed rubber wheel is not suitable: there is one on the upper and lower sides of the cold-pressed rubber wheel, and the pressure between them should be moderate. You only need to clamp the spring when adjusting the pressure.
