Description

Technical Field

[0001] This invention relates to the field of cork paper slitting technology, and in particular to a cork paper rewinding and slitting device and a hard-bonded cork paper. Background Technology

[0002] The paper (usually cork-colored or opaque white) used to wrap around the filter tip and attach the filter rod to the end of the cigarette stick. The printing ink and coating of the tipping paper must be non-toxic and meet food hygiene standards. The tipping paper must also have a certain degree of water resistance and wet strength. After the tipping paper is processed and manufactured, it needs to be slit and wound according to the specifications and dimensions customized by the customer. After being cut by multiple slitting discs, the width of each strip of tipping paper meets the requirements.

[0003] However, during the slitting process of tipping paper, the paper dust remaining on the slitting disc not only serves to insulate and store heat, but also affects the cut edge formation when cutting the tipping paper. Furthermore, the paper dust adheres to the slit tipping paper, resulting in significant residual paper dust when the paper is directly rewound after slitting. Subsequent processes require another cleaning process. The residual paper dust on the slitting disc mainly originates from two sources: first, paper dust falling from the blades directly adheres to the blades when the slitting disc comes into contact with the tipping paper; second, paper dust falling from the cutting edge falls into the slitting groove of the lower linkage roller, where the paper dust... When a large amount of paper dust adheres to the cutting groove, the bottom edge of the slitting disc extending into the cutting groove will be contaminated with the paper dust. During actual slitting, most of the paper dust generated at the cutting edge of the cork paper falls into the cutting groove of the linkage roller. Some of the paper dust in the cutting groove will fall off naturally as the linkage roller rotates. However, if the paper dust remaining in the cutting groove is not discharged in time, it will accumulate more and more, causing the bottom edge of the slitting disc to be directly contaminated with paper dust. This paper dust will reach the cutting edge of the cork paper as the slitting disc rotates, affecting the slitting and cleaning winding effect of the cork paper. Therefore, a cork paper rewinding and slitting device is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a tipping paper rewinding and slitting device. This device solves the problem that during the tipping paper slitting process, the residual paper dust on the slitting disc not only serves to insulate and store heat, but also affects the cut formation when cutting the tipping paper. Furthermore, the paper dust adheres to the slit tipping paper, resulting in a significant amount of residual paper dust when the tipping paper is directly rewound into a tube after slitting, requiring repeated cleaning in subsequent processes.

Both the inner and outer support layers are made of natural pulp, and the fluffy pulp layer is made of pulp containing hard fibers.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the tipping paper rewinding and slitting device unwinds the tipping paper body from the unwinding roller during the slitting process. A tensioning and pressing assembly is provided, and one end of the tipping paper body passes sequentially through an adjusting roller, a fixed pressure roller, another fixed pressure roller, and an adjusting roller before finally being retracted onto the take-up roller.

In this invention, the tipping paper rewinding and slitting device is equipped with a blade cleaning component. After slitting, debris remains on the surface of the cutting blade. Cleaning wiping cotton blocks are provided on both sides of the cutting blade. Under the pushing action of the compression spring, the cleaning wiping cotton blocks can contact the two sides of the cutting blade to clean the debris on the cutting blade. After a period of cleaning, the conveyor motor runs and drives the conveyor roller to rotate, which drives the cleaning wiping cotton blocks to adjust their position. The clean cleaning wiping cotton blocks will quickly contact the cutting blade. The replacement process does not require stopping the operation of the cutting equipment, and it is also convenient to quickly replace the cleaning wiping cotton blocks. In this invention, the tipping paper rewinding and slitting device includes a position adjustment component. During the slitting process, when the slitting width needs to be adjusted, the drive motor rotates, causing the rotating lead screw to rotate, thereby adjusting the position of the cutting disc and achieving the adjustment of the slitting width. The movement of the connecting rod causes the synchronous drive rod to move, which in turn moves the L-shaped moving plate, enabling the cleaning and wiping cotton blocks on both sides to move, ensuring that the cleaning and wiping cotton blocks are always located on both sides of the cutting disc, achieving synchronous adjustment.
