[0018] like Figure 1 As shown, the utility model provides a pulping machine for paper towel production, comprising a mixing barrel 1, a feeding pipe 2, a discharging pipe 3, a first motor 4, a fixed shaft 5 and two groups of crushing knives 6. The first motor 4 drives the two groups of crushing knives 6 to rotate to stir and crush the shredded paper.

[0019] An annular sliding groove is provided on the top of the mixing barrel 1. The cross-section of the annular sliding groove is convex. Two sliding plates 1.1 of corresponding shapes are slidably connected in the annular sliding groove. An annular plate 1.2 is connected to the lower sides of the two sliding plates 1.1. A second motor 1.3 is connected to the mixing barrel 1. The second motor 1.3 drives the annular plate 1.2 to rotate through a first transmission mechanism. The first transmission mechanism includes a meshing gear 1.4 and a gear sleeve 1.5. The gear 1.4 is connected to the output shaft of the second motor 1.3. The gear sleeve 1.5 is sleeved and fixed on the outer side of the annular plate 1.2. The gear 1.4 is driven to rotate by the second motor 1.3. The gear 1.4 gear drives the gear sleeve 1.5, and the gear sleeve 1.5 drives the annular plate 1.2 to rotate.

[0020] A rotating plate 7 is connected to the lower side of the annular plate 1.2, and fixed plates 7.2 are connected to both sides below the rotating plate 7. The two fixed plates 7.2 are arranged opposite to each other, and a bearing seat is connected to each fixed plate 7.2. A rotating screw rod 7.3 is inserted in each bearing seat, and a threaded sleeve 7.4 is threadedly driven on each screw 7.3. The lower side of the threaded sleeve 7.4 is connected to a vertical shaft 9, and two groups of fixed knives 10 are connected to each vertical shaft 9. The threaded sleeve 7.4 is threadedly driven by the screw rod 7.3, and the threaded sleeve 7.4 drives the vertical shaft 9 to move, thereby driving the fixed knife 10 to move.

[0021] Two sliding grooves 7.1 are provided on the lower side of the rotating plate 7. The two sliding grooves 7.1 are symmetrically arranged. A sliding plate 8 is slidably connected in each sliding groove 7.1. The sliding plate 8 is connected to the threaded sleeve 7.4.
