The device uses the principle of electromagnetic induction, and the aluminum foil on the bottle mouth instantaneously generates high temperature, and then the aluminum foil piece is fused on the bottle mouth to achieve the sealing function. It has good moisture-proof, mildew-proof and anti-counterfeiting effects, thus prolonging the storage time of articles.
Sealing machine features:
High-speed sealing, used with assembly line, suitable for the production of high-volume products (sealing);
2 sets of movements (main board), 2 sets of power amplifiers, which can output high-power current, meet high-speed sealing; equipment with automatic feeding device, more convenient for high-speed production; optional automatic aluminum foil-free bottle removal device, automatic sealing Bottle counter; high sealing efficiency (0-200 bottles / min), good sealing quality; equipment automatic start and stop work, continuous work, easy to operate; all stainless steel mold forming shell, beautiful and generous, equipment work is stable and reliable; non-contact heating, adapt The sealing of various plastic bottles and composite plastic bottles is in compliance with GMP standards; the materials of the sealed containers may be polypropylene (PP), polystyrene (PS), polyester (PET), polyethylene (PE), ABS and Glass, etc. (The company also provides various materials for induction aluminum foil film).
Everyone knows that packaging machinery has been used for a long time, especially in continuous working and overload situations, it is prone to some electrical faults and mechanical faults, such as sealing machine: the sealing is not strong, the machine stops and stops, the fuse is blown at the start, During the operation, the “beep†is emitted, the temperature is uncontrollable, the finished bag is deformed and bent at the seal, and bubbles or irregular marks appear on the seal of the seal.
The following small series introduces you how to deal with several common fault problems. Let's take a look at it.
1. The seal is not strong
Sealing is not one of the common failures of the continuous sealing machine. The sealing is not strong. There are three layers of meaning: 1 The sealing of the bag cannot be sealed; 2 Under the pressure of the sealing knife, although the bag is sealed, it is squeezed slightly or When peeling and peeling, the seal will be cracked again. 3 When the peeling test is carried out on the sealing part, half of the sealing is firm and half separated. The quality of the sealing of the bag is still unsatisfactory, because the contents are squeezed during storage and transportation. Easy to miss. This situation often occurs when the composite lining is OPP and blown PE.
There are mainly the following reasons for causing * kinds of faults.
(1) The heat sealing temperature is not enough:
Under normal circumstances, the composite bag with OPP as the lining, when the total thickness of the bag is 80-90μm, the heat sealing temperature should reach 170-180 °C; the total thickness of the composite bag with PE as the lining is 85-100μm. When the temperature is controlled, it is controlled at 180 to 200 °C. 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:
Sealing is not related to the speed of the sealing machine. If the speed is too fast, the seal will be transferred to the cold pressure for cooling in the future, and the heat seal quality requirement will not be achieved.
(3) The pressure of the cold-pressing rubber wheel is not suitable: there is one of the upper and lower sides of the cold-pressing rubber wheel, and the pressure between them should be moderate. When adjusting the pressure, only the spring should be clamped.
Well, the above is about the operating principle of the electromagnetic induction aluminum foil sealing machine and the whole content of the fault handling, I hope to be helpful to everyone.
About the operation principle and fault treatment of electromagnetic induction aluminum foil sealing machine
Electromagnetic induction aluminum foil sealing machine is widely used in the sealing of containers for medicines, liquid medicines, spices, detergents, milk, beverages, foods, chemical products, etc., and functions as sealing, anti-counterfeiting and anti-theft. The machine has reasonable design, reliable performance, convenient operation, high production efficiency, small area, light weight, low noise and low consumption. It is widely used in medicine, food, oil, daily chemicals, pesticides and other industries.
