DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] AsFigure 1 The adjustable spacing leather roll slitting device in the embodiment shown comprises a rack 1, a feeding roller 2, a collecting roller 3, a driving motor 4, a slitting roller 5, a plurality of slitting cutters 6 and a plurality of supporting rollers 7. The feeding roller 2 and the collecting roller 3 are respectively rotationally arranged on the two sides of the rack 1. The driving motor 4 is arranged on the side of the collecting roller 3 and is in transmission connection with the feeding roller 2 through a chain 8 and a sprocket 9. The driving motor 4 drives the rotation of the collecting roller 3, so as to wind the leather from the feeding roller 2 onto the collecting roller 3.

[0019] The slitting roller 5 is arranged on the top of the rack 1 at a position between the feeding roller 2 and the collecting roller 3. The plurality of slitting cutters 6 are adjustably arranged on the slitting roller 5 at intervals. The plurality of supporting rollers 7 are arranged side by side on the rack 1 and are located on the lower side of the slitting roller 5. During the winding of the leather, the plurality of slitting cutters 6 on the slitting roller 5 slit the leather, so as to slit the whole leather into a plurality of narrow strips.

[0020] A first guide roller 10 is arranged above the feeding roller 2 on the rack 1. A second guide roller 11 is arranged above the collecting roller 3 on the rack 1. The first guide roller 10 and the second guide roller 11 both play a guiding and transition role of the leather, so as to ensure the smooth operation of the leather.

[0021] As shown in Figure 2 The slitting cutter 6 comprises a first clamping block 61, a second clamping block 62, a blade 63 and a fixing bolt 64. The first clamping block 61 and the second clamping block 62 are respectively clamped on the circumferential surfaces of the slitting roller 5. The blade 63 is arranged on the second clamping block 62 and faces the side of the leather. During the movement of the leather, the blade 63 slits the leather.

[0022] A plurality of first through holes 51 are arranged at equal intervals on the slitting roller 5. Second through holes are arranged on the corresponding positions of the first clamping block 61 and the second clamping block 62. The fixing bolt 64 penetrates the first through holes 51 and the second through holes to lock the first clamping block 61 and the second clamping block 62 on the slitting roller 5. By adjusting the positions of the first clamping block 61 and the second clamping block 62 in different first through holes 51, the distance between the two slitting cutters 6 can be changed, so as to change the slitting width.
