Packaging film wrinkling cause analysis and filming machine operating points

Analysis of Causes for Wrinkling of Decidual Film and Points for Operation of Film Forming Machine—

1. Analysis of cause of wrinkling of diaphragm

(1) The unilateral tension of the raw material or the tightness of the two sides of the raw material causes the paper surface to be uneven and cause wrinkling of the film.

(2) The difference in the temperature resistance of the raw materials causes the deformation of the decoiled film after entering the oven.

(3) The quality of the film mulching machine is different. The buckwheat film wrinkles are caused by the deceasing of the decidua film.

(4) The operculum wrinkles are caused by the poor operation skills of the aponeurosis staff or improper operation.

2, the operating point of the film machine

(1) Place the squeezing machine on the special stand and place it on a stable and firm work bench. Then make a special film for the diaphragm, the height is lower than the edge of the film machine 5 mm in height, the width is 1600 mm, and the length is more than 1 meter.

(2) Put the material of the film or the idle film machine on the iron roller in front of the film machine. After entering the film machine, the coating surface will face upwards.

(3) Adjust the pressure regulator hand wheel on the film machine, raise the rubber roller, and then pass the material out of the film roll of the film machine by 10 cm.

(4) If you need to take the film also need to pass the cold laminating film out of the film machine roller 10 cm, placed on the top of the consumables, PVC film Chao Chao, film and consumables on both sides of the road must be aligned.

(5) Adjust the position of the consumables on the platform so that the tightness of both ends of the consumables is basically the same on the film machine. Then adjust the pressure-adjusting hand wheel on the film machine, lower the rubber roller, and set it to the idle position. The pressure at both ends must be the same.

(6) If the machine is empty, the handwheel can be shaken to move the consumables forward. The shaking must be uniform and the walking speed must be uniform. If there is no wrinkle after 5 meters away, it means there is no quality problem for consumables.

(7) If film is needed, first fold the cold lamination film release paper inward to expose the glue surface on the PVC film. Then * hand wheel, first apply the glue surface to the consumables, and then add the cold lamination film as a whole. Turn to the rear of the rubber roller, and slowly open the cold film from the folding place. At this time, turn the rubber roller to rotate it forward. Remove the release paper slowly as the roller rotates, and keep the tightness of both sides consistent. A certain amount of effort until the end of cold weather.

(8) If the consumables are misaligned in the process of walking or filming, it means there is a problem with the operation and nothing to do with consumables.
