After the paper box produced by the box gluing machine is glued and formed, the bonded part cracks. Cause analysis of degumming of carton in box gluing machine is as follows.

1.Cause analysis of degumming of carton in box gluing machine: the viscosity of the glue is not enough, and the amount of glue is insufficient.

Solution: Glue boxes generally use white latex, which is diluted with water during use, which also reduces the viscosity. When the viscosity is not enough, the glue with higher concentration can be redistributed. If the amount of glue is insufficient, the gap between the rubber wheel and the glued surface of the cardboard can be increased, and the amount of glue can be increased.

2. Cause analysis of degumming of carton in box gluing machine:the temperature of the box gluing machine workshop affects the viscosity of the glue (especially in summer and winter).

Solution: Control the temperature of the paste box workshop at about 20°C through temperature adjustment devices such as air conditioners to ensure the normal viscosity of the glue.

3. Cause analysis of degumming of carton in box gluing machine:before using the white latex, it is not carefully checked, resulting in the use of expired or deteriorated glue.

Solution: Before using the white latex, it should be properly stored and sealed. Its shelf life is generally 1 year.

4. Cause analysis of degumming of carton in box gluing machine:the white latex used does not match the cardboard.

Solution: As there are many types and grades of white latex on the market, white latex should be selected according to the specific characteristics of the product.

5. Cause analysis of degumming of carton in box gluing machine:the glued part of the carton which producted by box gluing machine is glazing or coated to prevent the glue from penetrating into the cardboard.

Solution: Before gluing the carton, install a cardboard edging device to grind the glued part of the carton before gluing to eliminate the influence of glazing or laminating. If possible, you can also use hot melt glue instead of white latex, and use the temperature of the hot melt glue to melt the glazing film to facilitate the bonding of the glue.

6. Cause analysis of degumming of carton in box gluing machine:after the paper box which producted by box gluing machine is glued, the pressure on the glued part at the folding part is not enough, the machine speed is too fast, and the pressure time is not enough, so that the glue can not penetrate into the cardboard in time, reducing the bonding effect.

Solution: Increase the pressure of the crimping roller, appropriately reduce the machine speed, and extend the pressing time.
