A cushion sheet production module configured to produce a cushion sheet and comprising a feeding direction to produce the cushion sheet, the cushion sheet comprising a first sheet and a buffer layer, the cushion sheet production module comprising:
- a first unreeling unit configured to unreel the first sheet at a first feeding speed, wherein the first sheet is continuously fed along the feeding direction after the first sheet is unreeled;
- a buffer layer feeding unit configured to unreel the buffer layer at a changing speed along the feeding direction, the buffer layer arranged above or below the first sheet and opposite to the first sheet, wherein a surface of the buffer layer facing the first sheet is coated with glue, or a surface of the first sheet facing the buffer layer is coated with glue, or the surfaces of the buffer layer and the first sheet facing each other are coated with glue, the glue configured to paste the first sheet and the buffer layer together;
- a cutting unit arranged behind the buffer layer feeding unit along the feeding direction, and configured to roll and cut the buffer layer during feeding the buffer layer, positions that the buffer layer are cut arranged on the buffer layer at intervals and set perpendicular to the feeding direction;
- and wherein
- the buffer layer is cut to be separated into a plurality of cushion units arranged in a row from beginning to end, each of the plurality of cushion units comprising a first end and a second end arranged along the feeding direction and opposite to each other, the second end of a previous cushion unit adjacent to the first end of a current cushion unit;
- a paper pressing unit arranged behind the cutting unit along the feeding direction and configured to roll and press against positions of the glue set on the first sheet and/or the buffer layer to paste the first sheet and the buffer layer;
- and wherein each cushion unit is sequentially fed to the paper pressing unit from the first end to the second end, and the plurality of cushion units are fixed on the first sheet after the plurality of cushion units is pressed against by the paper pressing unit;
- and wherein
- the changing speed comprises a second feeding speed and a third feeding speed, the third feeding speed equal to the first feeding speed and the second feeding speed smaller than the first feeding speed;
- and wherein
- a plurality of intervals is formed on the first sheet, each of the plurality of intervals arranged between the first end of the current cushion unit and the second end of the previous cushion unit;
- and wherein after the buffer layer is cut by the cutting unit, the buffer layer feeding unit is continuously fed at the second feeding speed, until one of the plurality of intervals is reserved on the first sheet, and when the first end of the current cushion unit is fixed on the first sheet, the buffer layer feeding unit is fed at the third feeding speed continuously and synchronously with the first sheet.
