Common Problems in Bag Making and Analysis of Causes

Bag machine failure, generally by controlling the display or alarm on the man-machine interface to find the point of failure; can also interface on the test page to test the fault to find the point of failure.

1), optoelectronic tracking can not keep up, the optical loss of shutdown alarm.

the reason:

A, photoelectric head and the distance between the film is too small or too large, the appropriate distance of about 10mm;

B, photoelectric and film is not vertical;

C, the film after sealing severely deformed elongated, wrinkling;

D, photoelectric frame is not locked, in the process of stringing bag;

E, photoelectric sensitivity is not adjusted well;

F, bright, dark pass is not set up;

G, unreasonable tracking line;

H, hot row with pressure material phenomenon;

I, photoelectric tracking range setting unreasonable.

2), printed bag size is not accurate, suddenly long suddenly short.

the reason:

A, printing or composite caused by bag length are not allowed;

B, traction roller with slip phenomenon;

C, hot row with pressure material phenomenon;

D, transverse sealing tension is too large;

E, expansion sleeve whether there is loosening

3), bags of travel material serious

the reason:

A, roller pressure imbalance;

B, the fuselage frame does not have the school level, the fuselage deformation distortion;

C, bag tension is too small;

D, film thickness uneven;

E, film composite uneven, take the unilateral

4), bag deformation Qiaojiao serious

the reason:

A, bag tension is too large;

B, bag temperature is too high;

C, hot row with pressure material phenomenon;

D, film composite tension uneven;

E, film thickness uneven;

5), the machine does not start up

the reason:

A, the main motor power phase;

B, the main motor Hall switch or proximity switch signal loss;

C, the main motor inverter or servo drive fault protection;

D, line break, poor contact and so on

6), traction cots do not drag material

the reason:

A, the rubber roller stuck, there is no pressure under the roller;

B, rubber roller and servo motor connected expansion sleeve loose;

C, servo motor drive fault self-protection;

D, Servo motor thermal overload;

E, line break, poor contact and so on

7), hot stitched with bubbles

the reason:

A, hot knife is not clean, sticky dirt;

B, hot knife deformation or damage;

C, hot pressing temperature is too low;

D, hot pressing pressure is too small;

E, silicone pad aging hard.

8), bag drawing

the reason:

A, put the gantry of the inclined bar and the "V" board is not included in the accumulation of dirt or velvet fabric;

B, before and after cutting the upper and lower feeding material to ease the folder too tight;

C, aluminum guide roller bearing damage stuck does not turn;

D, high-temperature hot cloth sticky glue, waste side of the dirt.

9), bag sealing is not strong

the reason:

A, sealing hot enough;

B, sealing hot pressure is too low;

C, hot row pressure is too small;

10), stand-alone bag hole punch hole at the bottom are not allowed

the reason:

A, film traction tension instability;

B, traction when there is pressure material phenomenon;

C, sealing hot temperature is too high, leading to serious deformation of the film;

D, Servo motor traction error.

11), the closure of the organ and stand-up bags of four and two layers of the intersection of hot and not hot

the reason:

A, temperature, pressure problems;

B, hot knife deformation problem;

C, independent pocket hot knife design is unreasonable;

D, hot knife pressure is not enough.

12), zipper hot seam wrinkled, it is difficult to see

the reason:

A, zipper is not hot prison;

B, zipper template too tight;

C, sealing hot temperature is too high;

D, tension is too large;

E, zipper sealing temperature and film sealing temperature does not match

13), zipper hot is not strong

the reason:

A, film and zipper does not match (material does not match, the temperature does not match);

B, film string against the (mainly for the albuginea);

C, Zipper hot knife is not smooth;

D, roll hot cloth with folds;

E, hot knife or hot cloth on the dirt

14), zipper can not open or from the opening

the reason:

A, zipper mounted anti, it will not open;

B, the temperature is too high and hot knife on the zipper slot is too shallow;

C, the zipper is squeezed by the rubber roller will appear from the opening phenomenon.
