Principle structure of plastic bag sealing machine
1. The machine is composed of a frame, a deceleration and speed regulation transmission mechanism, a heating and radiating mechanism, a sealing and printing mechanism, a conveying device, and an electrical and electronic control system.
2. turn on the power, and each organization starts to work. After the electric heating element is energized, it heats up, so that the upper and lower heating blocks are heated up sharply and adjusted to the required temperature through the control system; the impression wheel rotates; the cooling system starts to cool as needed; the conveyor belt is transferred and adjusted to the required speed by the speed control device .
3. When the package containing the articles 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 zone, and the heat of the heating block is transferred to the sealing part of the bag through the sealing belt , The film is heated and melted, and then passed through the cooling zone to make the surface temperature of the film drop appropriately, and then rolled through the knurling wheel (or printing wheel), so that the upper and lower plastic films of the sealing part are glued and pressed into a net pattern (or printing). Mark), 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.
How to use plastic bag sealing machine
1. Inspection and preparation before starting up:
①This machine adopts 220V single-phase AC power supply and is equipped with a three-pin socket with shell grounding. Before use, check whether the voltage of the power supply meets the requirements, whether the wiring is firm, and whether the bottom line is connected.
②Adjust the height of the sealing machine according to the operator’s working conditions.
③Check whether the lubrication of each rotating part is good, and inject proper amount of lubricating oil.
④If the heating tube is used for the first time or when the interval is too long, the electric heating tube may become damp and the insulation resistance may decrease (normal). It should be preheated at low temperature for half an hour before normal operation.
⑤Adjust the height and front and back 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 special meniscus wrench to loosen the bridge gear nut, adjust it properly and tighten it; adjust the position of the sealing width positioning frame according to the sealing size.
2. boot operation:
①Press the power switch of the plastic bag sealing machine first, and the indicator light inside the button is on.
②Turn the speed control knob to adjust the conveyor belt to the required running speed.
③Press the heating switch, the indicator light in the button is on, and then turn 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 perm head starts to heat up. When the temperature reaches the specified value, the green light is off The red light is on and the sealing machine can start working.
④Press the fan switch as needed (the thin layer of material needs to be cooled), the indicator light in the button is on, and the cooling fan is activated.
3. shutdown operation:
①In order to prolong the service life of the sealing tape, the heating switch must be turned off (the button indicator light is off) before stopping, the temperature of the ironing head will drop, and the sealing tape will continue to run for a period of time.
②After about half an hour, the fan switch and power switch can be turned off, and the whole machine stops. At this time, the indicator light in the button is off.
