What is a wrapping paper tube?

1. Data paper slitting: The sand tube paper is determined to be the main paper with uniform thickness, low moisture content and smooth appearance, and impregnated paper is selected as the surface paper; according to the specifications and dimensions required to manufacture high-end paper tubes in Dongguan, the sand tube paper tube The large rolls and the large rolls of surface paper are placed in the slitting machine for slitting to obtain the required size of paper tape;

2. Reeling tube: the glued paper tape is wound into a tube on the active tube reeling machine;

3. Rough cutting: Put the Dongguan high-end paper tube on the resin-coated paper tube through the air dryer at a constant speed, and then roughly cut it into a certain length of paper tube section;

4. Fine cutting: Roughly cut the extruded paper tube according to the required specifications. After cutting, the end surface of the paper tube is chamfered, coated and processed, and then packaged to complete the seamless and high-grade appearance. Manufacture of paper tubes.

5. Paper tube drying: Put the rough cut paper tube section into the drying room for drying until the water content of the paper tube is less than 10%;

6. Paper tape gluing: How many layers of the main paper tape and the beveled surface paper tape are sequentially displaced layer by layer from top to bottom and placed in parallel on the paper tape gluing machine. Coat a layer of paper tube symmetrically with the upper surface of the surface paper tape with special glue;

7. Extrusion molding: After cooling the dried paper tube sections to room temperature, they are put into the molding die preheated to 150-280℃ to develop internal extrusion molding, so that the outer surface of the paper tube has been coated The resin is fully cured; the molding temperature of the mold is 150-280℃

8. Groove treatment: put the surface paper tape into the beveling machine to develop groove treatment on both sides of the tape; film paper tube

9. Surface coating: After the development of grinding treatment on the surface of the wound paper tube, the thermosetting resin is evenly coated on the surface
