An Attempt to Produce Composite Board Paper from Corrugated Cardboard Production Line

Is it only possible to produce corrugated cardboard from a corrugated cardboard line? Faced with a huge amount of equipment, we are whimsical: to increase equipment utilization and give it new features, we must let "chicken into the water, duck shelves!"
Our company originally planned to set up a set of paperboard composite equipment. After inspection, we discovered that the working principle of the equipment was similar to that of the gluing and drying machines of the corrugated board line. Therefore, we performed a “Huang Ni Xiu Hu”. Try.
We know that the working principle of the compound paper machine is to prepare the composite base paper and face paper according to the required specifications, and install them on the non-shaft bracket respectively. After being preheated by the preheater, it is compounded, calendered, and then rotated. After drying in the drying cylinder, it is wound onto a roll of roll and finally rewinded to obtain the finished product. Obviously, the dryers of the corrugated line dryer and the compound paper machine work in different ways. The corrugated line dryer presses the conveyor belt through a plurality of pressure rollers so as to drive the cardboard to slide on the hot plate to finish drying and setting. Whether the composite paper passes the dryer is the key to the success or failure of this attempt. After testing more than 130g single-layer base paper can successfully pass through the drying tunnel, the next problem to be solved is the roll paper mechanism. We refer to the automatic paper roll holder for papermaking equipment. A paper roll holder is made at the end of the dryer near the main transfer wheel of the conveyor belt. The roll paper roll on the roll paper holder is driven by the rotation of the transfer wheel to do the reverse movement. Roll paper process.
After that, we installed base and face paper on the non-shaft bracket in front of the triple preheater. 105 glue was injected into the plastic box of the gluing machine, and the base paper was put down to put down the gluing machine ballast roller, and the compounded board paper would be glued. After being fed into a drying tunnel, it is rolled into a web by a roll-up mechanism. The test run was very successful and it worked well. We have repeatedly used different specifications of corrugated paper composite test, with 60g white glossy paper, 220g boxboard composite whiteboard paper results are satisfactory, rewinding for carton production can be comparable with professional manufacturers of similar products. Therefore, we believe that the biggest advantages of using corrugated-cord composite paper are: good flatness, uniform tension, moderate moisture content (water content tested below 12%), composite paper speed up to 300g below 300g can be increased to 80min; the disadvantage is the whole Larger running resistance, the main motor power is more than double the same yield of the compound paper machine.
It should be noted that before starting the machine, it is necessary to separate the drive and clutch of the vertical and horizontal cutters. Such as composite 1000g, the above board paper, according to customer requirements can be pushed on the clutch file directly vertical and horizontal cut film; composite paper according to production requirements, steam pressure, temperature, flexible control of the amount of glue and speed; after the dryer cutting machine If it is hindered from being removed, it is better to install four small wheels in the lower part, laying the track on the ground, and freely in and out according to production requirements; the angle and height of the roll holder can vary from device to device.

The above situation is for reference only if you are interested in not visiting. (Shan Xiaojing)
