Three edge-sealing bag making machine in use process will appear many problems, in the process of using to learn through these problems to master the use of the machine, the machine can use time longer, we believe that in the process of use at the same time, you must have met these problems, the following to learn about these tricky problem together.

1. Problem 1: Bag warping occurs in the heat sealing of three-side sealing bag making machine. Reasons and solutions:

Reasons for heat sealing:

(1) the thickness of the composite film is inconsistent;

(2) the heat sealing temperature is too high or the heat sealing time is too long;

(3) in the longitudinal heat sealing part, the running track of the composite film is not straight;

(4) insufficient cooling;

(5) the curing time is not enough;

(6) The heat resistance of surface substrate film is poor;

(7) Improper tension matching control of the composite substrate in the composite process leads to residual stress after ripening and shaping, especially when the thickness of the composite film is thinner, such faults are more likely to occur.

Countermeasures adopted:

(1) Adjust the tension of the floating roller;

(2) choose the inner sealing base material with low temperature heat sealing;

(3) Adjust the heat sealing temperature to the appropriate temperature;

(4) Full cooling;

(5) Fully mature;

(6) Re-select the surface substrate film;

(7) adjust the tension of each part of the composite processing equipment, try to make the two kinds of composite base material shrinkage rate equal.

2, trilateral bag making machine in the manufacture of three side sealing bag in the process of the most problems is the bag making machine sealing brittle and brittle broken situation, this situation is particularly annoying, not the bag can not be used normally, and will cause a waste of resources, the following is to look at the reasons and solutions!

The reason:

(1) The heat sealing temperature is too high;

(2) too much pressure;

(3) the heat sealing time is too long;

(4) The edge of the sealing device on the bag-making machine is too sharp or the coated PTFE is damaged;

(5) the silicone rubber sealing at the bottom of bag-making machine is excellent;

(6) In the process of compounding and curing, part of the adhesive penetrates into the film. Due to the penetration effect of adhesive, the toughness (impact resistance) of the substrate decreases, and the brittleness increases.

(7) After cooling and placing the plastic composite bag, the heat sealing strength increases, but also tends to become brittle.

Countermeasures:

(1) According to the heat sealing characteristics of the material of the inner sealing layer, select the appropriate processing temperature, pressure and heat sealing time;

(2) Improve the surface state of the heat sealing knife on the bag-making machine to make the surface of the sealing device smooth;

(3) covered with ptfe cloth intact;

(4) Choose the appropriate hardness of silicone rubber pad.
