How to debug the tube filling and sealing machine

Before the use of the tube filling and sealing machine, the equipment must be tested as follows: 

• Check whether the actual operating speed of the equipment is the same as the speed of the initial debugging of the specification; 
• DETECT WHETHER THE LEISTER HEATER IS IN THE OPEN POSITION; 
• Test whether the compressed air supply pressure of the equipment meets the pressure requirements of the equipment when it is working normally; 
• Check whether the cooling water flows smoothly and whether the temperature of the cooling water is within the range required by the equipment; 
• Detect whether there is a phenomenon of dripping paste in the filling of the equipment, especially to ensure that the paste is not stuck in the upper part of the inner surface wall of the tube; 
• The inner surface of the hose should not be in contact with anything to avoid contamination of the inner surface wall of the hose; 
• Check whether the inlet air of the LEISTER heater is normal 
• Detect whether the temperature detector inside the heater is in the correct position

For each action produced by the equipment, one by one in the manual mode of the machine, to see if there is any abnormality.
After the above initial testing, let's look at some common specific questions:

Fact 1: 
Excessive melting is usually caused by high temperatures. At this time, it is necessary to check whether the actual temperature is the temperature required for the normal operation of the hose. 

The actual temperature on the temperature display should be relatively stable at the set temperature (normal deviation range is between 1°C and 3°C).

Fact 2: 
If there is an unevenness in the safety of the tail sealing, the height of the safety line can be compared with the left and right crosses through the two branches after sealing, and if there is an inconsistency between the left and right, it is necessary to adjust the balance of the fixed position of the heating head.   

Fact 3: 
There is a phenomenon of ears on one side: firstly, check whether the heating head is correctly placed in the nest of the heating head, and there is a card slot on the side of the heating head; The perpendicularity of the heating head to the hose underneath is then checked. 

Another possible cause of the phenomenon of ears on one side is the deviation of the parallelism of the two clamps. 

Deviations in the parallelism of the clamp can be detected by a spacer between 0.2 and 0.3 mm, or by manually sealing the plate so that the plate is closed and illuminated from the bottom up with a mobile phone light source to see the gap.

Fact 4: 
The end of the hose starts to crack in the middle of the hose, and if the heating head is not large enough, please replace it with a larger one. The size of the heating head is determined by inserting the heating head into the hose and then pulling it out, feeling a slight suction force when pulling it out.                 

Fact 5: 
"Eye bags" appear under the end sealing safety line: In this case, the height of the air outlet of the heating head is wrong, and the height of the heating head mechanism can be adjusted as a whole.                  

Fact 6: 
Hose cut tail with a depression in the middle: This problem is usually caused by the wrong size of the cup and the hose is stuck too tightly in the cup. The opposite is when the hose gets stuck too loosely in the cup and the tube is picked up by the inner heating head.

The size of the cup should be judged by the fact that the hose should be sufficiently jammed in the cup, but when the tail is clamped, the cup should not affect the natural change in the shape of the hose. 

Phenomenon 7

After cutting the tail, if there is a deviation between the left and right heights, you need to adjust the angle of the cutter to make it balanced.

The above list is only a few common tail sealing problems, tube filling and sealing machine users also have to analyze and solve specific problems according to the specific situation.
