A first receiving groove 211 is provided on one side of the first connecting strip 21 facing the first upper groove 111, so that a first connecting groove 4 is formed between the first connecting strip 21 and the upper surface of the first connecting end 11. A first hot melt strip 22 is provided on the bottom surface of the first receiving groove 211. The first connecting groove 4 matches the second connecting end 12.

[0037] The second connecting structure 3 includes a second connecting strip 31 arranged on the first lower groove 121, and a second accommodating groove 311 is provided on the side of the second connecting strip 31 facing the first lower groove 121, so that a second connecting groove 5 is formed between the second connecting strip 31 and the upper surface of the second connecting end 12, and a second hot melt strip 32 is provided on the bottom surface of the second accommodating groove 311, and the second connecting groove 5 matches the first connecting end 11.

[0038] With the above structure, when the head and tail of two rolls of absorbent paper are connected together, since along the width direction of the absorbent paper body 1, one end of the absorbent paper body 1 is provided with a first connecting end 11, and the other end is provided with a second connecting end 12, the upper surface of the first connecting end 11 is provided with a first upper groove 111, and the lower surface of the second connecting end 12 is provided with a first lower groove 121, the first upper groove 111 is provided with a first connecting structure 2, and the first lower groove 121 is provided with a second connecting structure 3; the first connecting structure 2 includes a first connecting strip 21 provided on the first upper groove 111, a first connecting strip 21 provided on the first lower groove 121, and a second connecting strip 3 provided on the first lower groove 121. The connecting strip 21 is provided with a first receiving groove 211 on the side facing the first upper groove 111, so that a first connecting groove 4 is formed between the first connecting strip 21 and the upper surface of the first connecting end 11. The bottom surface of the first receiving groove 211 is provided with a first hot melt strip 22. The first connecting groove 4 matches the second connecting end 12. The second connecting structure 3 includes a second connecting strip 31 provided on the first lower groove 121. The second connecting strip 31 is provided with a second receiving groove 311 on the side facing the first lower groove 121, so that a second connecting groove 5 is formed between the second connecting strip 31 and the upper surface of the second connecting end 12. The bottom surface of the second receiving groove 311 is provided with a second hot melt strip 32, and the second connecting groove 5 matches the first connecting end 11. Therefore, the second connecting end 12 of the first roll of absorbent paper can be embedded in the first connecting groove 4 of the second roll of absorbent paper, and the first connecting end 11 of the second roll of absorbent paper can be embedded in the second connecting groove 5 of the first roll of absorbent paper. Then, the second connecting strip 31 of the first roll of absorbent paper is attached to the first connecting end 11 of the second roll of absorbent paper, so that the second hot melt strip 32 of the first roll of absorbent paper is attached to the lower surface of the first connecting end 11 of the second roll of absorbent paper, and the first connecting end 11 of the second roll of absorbent paper is attached to the second connecting groove 5 of the first roll of absorbent paper. A connecting strip 21 is attached to the second connecting end 12 of the first roll of absorbent paper, so that the first hot melt strip 22 of the second roll of absorbent paper is attached to the upper surface of the second connecting end 12 of the first roll of absorbent paper. The position is heated to melt the first hot melt strip 22 and the second hot melt strip 32. The second connecting structure 3 and the second connecting end 12 of the first roll of absorbent paper are then connected to the first connecting structure 2 and the first connecting end 11 of the second roll of absorbent paper in an interlaced manner.
