 3、The method of machine operation and maintenance 

1, The operation method

1) Turn on the main machine power, the vertical and horizontal sealing bin, the printer warms up to the  setting temperature, the horizontal shaft seal and other some sliding parts need to plus the some lubricating oil.

2) pay attention to regular checks clean vertical and horizontal bin and jugged seal parts.

3) Check the installation date of the ribbon, the packaging film is correct, the electric eye position is correct.

4) Open the printer switch date, the packaging film to the predetermined position, the starter motor, a system of four to five empty bag and then  stop to check these empty bags is qualified, if qualified  you can open trenching switch working properly.

5) cutting off fill switch first, then turn off electrical power to avoid clip, damage the blade 

2, Machine maintenance

1) Machine should have direct contact with food before the work area with a detergent wash after work, the machine outside and horizontal sealing jaw vertical sealing jaw wipe clean with a dry cloth, give each horizontal shaft seal sliding parts add a little lubrication oil.

2)  More than half of the volume  remaining packaging film should be removed after work, preventing  bending  under pressure for reel  frame.

3) keep in the optical head cleaning, electrical parts should be dust and moisture.

4) Always check all parts of the screw, without loosening.

5) gearbox for the first time (new machines) using a 40 hours to replace oil ,afterwards change after 1,000 hours.

Note: For your safety, please install the earth ground.

4) "Test" display the operating status of the packaging machine;

5) "traction" shows seal packaging machine in which the film clip or open state;

6) "eyemark location "  left or right to adjust the  packaing film when become bag offset 

2, press the "manual ", the screen display as shown:


1) Touch the "one film moving ": film pull and  Pulley  as required operation  one time;

2) Touch "one bag making": make an empty bag  then machine stop ;

3) Touch the "hor sealing” :the horizontal sealing jaw sealing action once;

4) Touch the "vertical sealing": the vertical sealing Jaw sealing action once;

5) Touch the " Cutter": cutter running according to the set time;

6) Touch "film sending": when touch film sending, stop touching film stop sending

7)Touch “aerating”:gas filling one time when touch one time

9) Touch the "one filling": the feeding part feeding operation one time then stopped;

10) Touch the "putting discharge": the start discharge material, at this time only the  materail plate dish  runing , other program does not operate, can received  material with container

3.Press "function", the screen display as shown:


1)"ON": touch the right, display "On"   packaging machine according  the set function to work

2) "Off": Touch the right ,display "Off"  according to the setting  function ,  the packaging machine stop work

4, Press the "Parameter" screen shown in Figure:

Press the "next page" to select the following three content set



1) "Cutter Delay": indicates  the waiting time  that from the film finish transporting to the cutter of  electromagnetic valve  before electrical connections  (unit: seconds) which is set to the number of horizontal  sealing after sealing,subject to the Cutter  energized and release again   ;

2) "cutting ": indicates a cutter solenoid valve  energized time (unit: seconds) which is set to the number of knife can cut packaging film, without influenc for next bag falling .

3) "hor  sealing": indicates horizontal seal solenoid valve  energized time (unit: seconds) according to the thickness of the packaging film and packaging speed to set,subjuect to the packaging film sealing firm and not leak ;

4) "ver sealing": indicates vertical sealing solenoid valve  energized time (unit: seconds) according to the thickness of the packaging film and packaging speed to set,subjuect to the packaging film sealing firm and not leak 

5) " length ": Indicates when no electric eye color packaging film executable length (unit: mm) length setting should be two color ponit center distance + 10mm; (since the film pulling belt slip and other reasons, may actually packing length will be differences with the setting length, might need to increase  the length of the bag for correct);

3.Replace the motor or damage parts

GFCI trip heater tablet, motors and other electrical leakageCheck  One by one   the electrical exclude leakage phenomenon

Seal roll not hot (temperature display environment)1. The heating tube or temperature controler  burn or damage

2. Solid State Relays damage

3.Eletric  breaks 1. Replace the parts

2. Replacing the solid state relay

3.Check the electric line

 1, temperature display OPEN

2,digital beating  repeatedly1. Thermocouple turnoff

2, loose or damaged1.Check the electric line

2. Tighten or replace thermocouple

  machine stop temperature is normal  after turn on temperature falling boot小Environmental voltage is low, resulting in reduced heating element power Reduce packaging speed or increase power supply

  Film pulling synchronous belt make film broken or slip


 the paper too much resistance

release film is too few

Bag Forming damage

1. Check the paper surface and the surface of the bag former  whether excessive stickiness

2. Adjust the film release  amount of film feeding motor 

1.Bag Former remake

 Can not control the cutting point or half cut bag 1. Packaging film edge wrinkle or  caused by the photoelectric light path malfunction quality problems

2. The sensitivity of the optical head is not adjusted well

3. Pulling flim    belt slippage

4.Transport film is not long enough1. Replace the packaging film

2. Re-adjust the sensitivity of the optical head

1.Bag length adjustment 

Bag forming poor 1. Fomrer is not adjusted well

1.Roll film transferred to left or right 1. Re   adjust former

1.After adjustment  fixed roll

 bag sealing leaks1. Back and front of the horizontal sealing rollers sealing mouth are not parallel to each other 

 2. Temperature is not enough 3.Insufficient pressure1. Carefully adjust the horizontal sealing roller sealing parallelism

2. Moderately elevated temperature

3.Appropriate increase in pressure within the specified range
