[0007] Beating: Use 20% thick pulp for beating, and the beating degree after beating is 25-30°SR;

[0008] Screening: Use pressure screen to screen the pulp and separate impurities;

[0009] Web forming: set the web concentration to 0.3-0.321%, web pH value to 4.5-5.0, and the dryness after forming to 14-16%;

[0010] Pressing: Pressing is carried out in a four-roll three-press zone, and the pressing line pressure value is set. The dryness after pressing is 35-36%;

[0011] Drying: Place the paper sheets on a drying cylinder to dry;

[0012] Coating: Evenly apply the prepared coating on the dried paper surface to form a thin coating;

[0013] Drying and calendering: The coated paper is sent to the drying equipment for drying, and then calendered by the calender to make the paper surface smooth and high gloss;

[0014] Slitting and rewinding: Use slitting and rewinding device to slitting and rewinding the paper.

[0015] In this technical solution, a layer of special coating is applied on the basis, and then processed by calendering and other processes to make the surface of the paper have high gloss and excellent printing performance, thereby ensuring the printing quality of the tipping paper.

[0016] Furthermore, the rewinding device comprises a frame, on which are provided:

[0017] A rewinding roller, which is arranged at the tail end of the paper production line and is used to rewind the paper;

[0018] A slitting frame, which is arranged in front of the rewinding roller, and has a plurality of slitting knife groups arranged at intervals on the slitting frame, and the slitting knife groups are used to slit the paper being transported;

[0019] A knife rack, the knife rack is parallel to the slitting rack and spans above the paper, and a plurality of slitting knife groups are arranged on the knife rack, and the slitting knife groups on the knife rack are used to supply the slitting rack;

[0020] The auxiliary docking structure is used to assist the slitting knife group on the knife holder to slide onto the slitting frame.

[0021] In this technical solution, the cutting mechanism of most rewinding machines is currently fixed, which can only cut tipping paper of the same width, and has poor versatility. The present application can take the slitting knife group from the knife holder and dock it to the slitting frame through the auxiliary docking structure according to the needs, and then adjust the distance of the slitting knife group on the slitting frame according to the needs, so as to achieve the ability to cut paper of different widths.

[0022] Furthermore, the slitting knife assembly includes a knife disc and a knife rod, wherein the knife disc is fixedly arranged above the knife rod, one side of the knife rod is used for fixed connection with the slitting frame, and the other side of the knife rod is used for positioning connection with the knife frame.

[0023] Furthermore, a protrusion is provided on the side of the knife bar facing the slitting frame, and a positioning groove is provided on the protrusion. The shape of the positioning groove matches the first cross bar on the slitting frame. A fastening hole is also provided on the protrusion, and the fastening hole is used for a fastener to pass through to fix and seal the first cross bar in the positioning groove.

[0024] Furthermore, a positioning block is arranged on the side of the tool rod facing the tool holder, a guide groove having the same shape as the positioning block is opened on the tool holder, a magnetic block is arranged at the bottom of the guide groove, and a magnetic block is also arranged at the end of the positioning block.

[0025] In the technical solution, the knife rod is more stably positioned in the guide groove by magnetic attraction between the magnetic block at the bottom of the guide groove and the magnetic block at the end of the positioning block.

[0026] Furthermore, the guide groove has a size larger than the positioning block.

[0027] In the present technical solution, the size of the guide groove is larger than the positioning block, so that the positioning block of the tool rod can slide into the guide groove more easily, and when the positioning block slides out of the guide groove, it is flush with the lower side of the guide groove, so that the positioning groove on the protrusion on the other side of the tool rod can be stuck on the outside of the first cross bar after the adjustment.

[0028] Furthermore, the auxiliary docking structure includes a docking cylinder, the tool holder is slidably arranged on the frame, the docking cylinder is fixedly arranged on the frame, and the piston rod of the docking cylinder is fixedly connected to the tool holder to drive the tool holder to slide closer to or away from the slitting frame.

[0029] Furthermore, a lifting structure is provided on the slitting frame, and the lifting structure is used to drive the first cross bar to lift the slitting knife group up and down to approach or move away from the paper.

[0030] Furthermore, the lifting structure includes:

[0031] A lifting motor, wherein the lifting motor is fixedly arranged on the slitting frame;

[0032] A lifting screw rod is arranged on the side of the slitting frame perpendicular to the first cross bar and is rotatably connected to the slitting frame. The lifting screw rod is fixedly connected to the output end of the lifting motor. Both ends of the first cross bar pass through the slitting frame and are slidably arranged on the slitting frame up and down. A lifting nut is threadedly connected to the outer periphery of the lifting screw rod, and the lifting nut is fixedly connected to the end of the first cross bar.

[0033] In the technical solution, when the slitting knife group on the knife holder needs to be slid onto the slitting frame, the lifting motor is started to make the lifting nut slide upward on the lifting screw rod and move the first cross bar to the preset position. At this time, the docking cylinder is started to push the knife holder close to the slitting frame, and then the magnetic suction is manually resisted to make the positioning block and the positioning block of one of the slitting knife groups gradually slide outward along the slide-out guide groove, so that the positioning groove on the protrusion on the other side of the knife bar is stuck on the outside of the first cross bar after the height adjustment, and then the position of the slitting knife group in the transverse direction of the first cross bar is adjusted, and the first cross bar is fixed and blocked in the positioning groove with a fastener through the fastening hole, and multiple slitting knife groups are repeatedly moved to the first cross bar. Finally, the lifting motor is reversed to make the lifting nut slide downward on the lifting screw rod and move the first cross bar downward so that the knife disc of the slitting knife group contacts the paper and can cut the paper.

[0034] Furthermore, a tipping paper base paper is produced by adopting the above production process.

[0035] The beneficial effects of the present invention are:

[0036] 1. By coating a layer of special coating on the basis, and then undergoing calendering and other processes, the surface of the paper has high gloss and excellent printing performance, ensuring the printing quality of the tipping paper.

[0037] 2. This application can take the slitting knife group from the knife holder according to needs and dock it to the slitting frame through the auxiliary docking structure, and then adjust the distance of the slitting knife group on the slitting frame as needed to achieve the ability to cut paper of different width requirements.

[0038] 3. The magnetic block at the bottom of the guide groove and the magnetic block at the end of the positioning block are magnetically attracted to each other, so that the tool rod is positioned more stably in the guide groove.

[0039] 4. The guide groove is larger than the positioning block, so that the positioning block of the tool rod can slide into the guide groove more easily, and when the positioning block slides out of the guide groove, it is flush with the lower side of the guide groove, so that the positioning groove on the protrusion on the other side of the tool rod can be stuck on the outside of the first cross bar after the height is adjusted.
