The Printed Thick Cardboard Gift Paper Boxes Products Are Scrapped Immediately, Which May Be The Problem Of The Plastic Mesh Roller On The Compound Machine

The printed Thick Cardboard Gift Paper Boxes products are scrapped immediately, which may be the problem of the plastic mesh roller on the compound machine

I believe that many enterprises have encountered a similar phenomenon: hard printing of good film semi-finished products, but in the composite process "failure", it is regrettable. At this time, some soft bag factory will be attributed to the workers on the operation, in fact, you have not thought, may be the problem of composite machine plastic mesh roller.

1, soft bag factory in the purchase of dry compound machine, if there is no requirement, the original machine with the glue roller is generally between 80 lines and 120 lines, suitable for ordinary compound bag glue composite and single component adhesive use.

If the quality requirements of composite bags are relatively high, the composite machine should make a reasonable choice on the cable roller, determine the line number of the cable roller, in order to control the amount of glue and coating uniformity, improve the quality of composite bags.

2, there are many kinds of cable roller, only two kinds of dry compound machine for flexible packaging: one is conical, namely: pyramid (four pyramid type) and edge type, namely: truncated pyramid (four prism type).

At present, the dry compound machine for flexible packaging basically uses the four pyramid type cable roller. However, a certain number of mesh roller hole depth should also be in a certain range, the deeper the mesh of the mesh roller, the greater the capacity of the mesh, the more adhesive transfer, the service life of the mesh roller will become short, therefore, when choosing the mesh roller should pay attention to the depth of the mesh, can be directly consulted with the manufacturer of the production of the mesh roller.

3, the production form of cable roller, basically can be divided into two kinds: one is electric carving; The other is extruded by special equipment. In the way of production, the mesh of different cable roller is different, and the form of use is different.

In the use of scraper compound machine, should be strictly adjusted scraper Angle, but also control the amount of glue. General manufacturers basically use special equipment extrusion. The line number of the cable roller should be selected correctly according to the quality requirements of the packaging bag.

4, the specific selection method: the daily production of ordinary composite bag can use a single component adhesive, you can use 80 line -120 line on the glue roller.

The production of general composite packaging bags, the use of two-component adhesive, generally can choose 120 line -160 line of cable roller. Do their own high-grade packaging bags, in the compound requirements are more strict, the use of two-component polyurethane adhesive can generally choose 160 line-200 line of wire roller.

To sum up, conditional enterprises can spare some different network roller for use, after use, be sure to clean the net hole of the network roller to prevent blocking, such as long-term need not use bristle brush and ethyl ester repeatedly cleaning, and finally clean with dry cloth, otherwise cause blocking network after ethyl ester cleaning not to use a special washing solution for cleaning.
