1. What is a plastic bagBag sealing machine
Plastic bag sealing machine is a kind of plastic bag sealing machine suitable for medicine, pesticide, food, daily chemical , Lubricating oil and other industries of aluminum foil bags, plastic bags, sealing machinery for composite bags, can seal plastic films of various materials (PE, PP, aluminum film, etc.). The plastic bag sealing machine has the advantages of firm sealing and high efficiency; simple and compact structure, small size; beautiful appearance, advanced technology, low power consumption; convenient operation and maintenance.
Second, the principle and structure of the plastic bag sealing machine
1. The plastic bag sealing machine consists of a frame, a deceleration and speed control transmission mechanism, a heating and cooling mechanism, It is composed of sealing and printing mechanism, conveying device and electrical and electronic control system.
2. Turn on the power, and the agencies start working. After the electric heating element is energized, it heats up, so that the upper and lower heating blocks heat up rapidly and are adjusted to the required temperature through the control system. The imprinting wheel rotates, and the cooling system starts to cool according to the needs. The conveyor belt is rotated and adjusted to the required speed by the speed regulating device. .
3. When the package with the items is placed on the conveyor belt, the sealing part of the bag is automatically sent to the two sealing belts in operation and brought into the heating area, and the heat of the heating block passes through the sealing belt. Transfer it to the sealing part of the bag to make the film melted and softened by heat, and then pass through the cooling zone to make the surface temperature of the film drop appropriately, and then roll it through a knurling wheel (or printing wheel) to bond and press the upper and lower plastic films of the sealing part. The mesh pattern (or printed logo) is produced, and then the sealed packaging bag is sent out of the machine by the guiding rubber belt and the conveyor belt to complete the sealing operation.
Three. PlasticHow to use the bag sealing machine
1. Inspection and preparation before starting the machine
strong>
(1) The sealing machine adopts 220V single-phase AC power supply and is equipped with a three-pin socket grounded on the shell. Before use, check whether the voltage of the power supply is combined with the requirements, whether the wiring is firm, and whether the bottom line is connected.
(2) Adjust the height of the sealing machine according to the working conditions of the operator.
(3) Check whether the lubrication of each rotating part is good, and inject an appropriate amount of lubricating oil.
(4) If it is used for the first time or if the use interval is too long, the electric heating tube may be damp and the insulation resistance will decrease (normal). It should be preheated at a low temperature for half an hour before normal operation.
(5) Adjust the height and front and rear positions of the conveyor table of the automatic film sealing machine according to the size and filling volume of the packaging bag. For height adjustment, use a random special meniscus wrench to loosen the bridge gear nut, adjust it properly and then tighten it; adjust the position of the sealing width positioning frame according to the sealing size.
2. Power on operation
(1) Press the power switch of the plastic bag sealing machine first, and the indicator light in the button is on.
(2) Rotate the speed control knob to adjust the required running speed of the conveyor belt.
(3) Press the heating switch, the indicator light in the button is on, and then rotate the knob under the temperature controller to make the pointer point to the desired temperature value. At this time, the green light in the temperature controller is on, and the ironing head starts to heat up. When the temperature reaches the specified value, the green light is off and the red light is on, and the sealing machine can start to work.
(4) Press the fan switch as required (thin layer material needs to be cooled), the indicator light in the button is on, and the cooling fan is started.
3. Shutdown operation
(1) In order to prolong the service life of the sealing tape, the heating switch must be cut off (the button indicator light is off) before the machine is shut down. The temperature of the ironing head drops, let the sealing tape continue to run for a while.
(2) After about half an hour, the fan switch and power switch can be disconnected, the whole machine will stop, and the indicator light in the button will be off at this time.
