The two ends of the upper roller group 31 and the lower roller group 32 are rotatably connected to the support table 2 respectively. The slitting machine 3 is used for slitting the plate, and the slitting between the plates is achieved by the mutual rotation cooperation between the upper roller group 31 and the lower roller group 32. A straight slot 24 is opened on the support cover 22, and a movable plate 241 is provided in the straight slot 24. The upper roller group 31 is movably connected to the movable plate 241 and can move along the height direction of the movable plate 241. The lower roller group 32 is installed on the movable plate 241, wherein the spacing formed between the upper roller group 31 and the lower roller group 32 is changed by adjusting the movable plate 241 and cooperating with the notch, so that the upper roller group 31 can be adjusted up and down in the straight slot 24, so that the equipment can adapt to the needs of slitting plate processing of plates of different thicknesses;

[0030] Please refer to Figure 1-Figure 2 As shown, the movable plate 241 is threaded with a screw rod 242, one end of the screw rod 242 is rotatably connected to the support platform 2, and the other end is connected to a hand wheel 243 for transmission. The screw rod 242 is rotatably connected to the support cover 22, and the movable plate 241 rotates the hand wheel 243. A bevel gear is fixed on the hand wheel 243. The bevel gear can change the transmission direction of the force when the hand wheel 243 is rotated. The bevel gear meshes with the bevel gear on the screw rod 242 for transmission, so that the screw rod 2 can be driven when the hand wheel 243 is rotated. 42 is rotated to cooperate with the movable plate 241, so that the movable plate 241 slides up and down along the slide groove in the straight slot 24 to change the height of the movable plate 241, so that the height of the upper roller group 31 connected to the movable plate 241 is changed. Among them, the handwheel 243 drives the movable plate 241, which is an existing and conventional technology. The handwheel 243 can synchronously drive the movable plates 241 at both ends of the support platform 2 to perform synchronous height adjustment. The specific internal structure is the transmission of bevel gears and rotating shafts, which is an existing and conventional technology.

[0031] Please refer to Figure 2As shown, the movable plate 241 is provided with a plurality of arc grooves 2411, and the arc grooves 2411 are distributed along the length direction of the movable plate 241, and an adjustment block 2412 is provided in the arc groove 2411, and the adjustment block 2412 can move along the height direction of the arc groove 2411, and an adjustment screw rod 2413 is provided on the adjustment block 2412, and the adjustment screw rod 2413 is threadedly matched with the adjustment block 2412, and its two ends are rotatably connected to the movable plate 241, and a nut is fixed on the top of the adjustment screw rod 2413.

When the thickness and hardness of the plate are low, the plate only needs one upper roller shaft 3 11 can realize the stripping of the plate, and there is no need for the contact between the other upper rollers 311 for cutting the plate and the plate, which may cause the plate to be cut incorrectly. In this embodiment, the upper roller group 31 can be adjusted in height along the support cover 22. By setting each upper roller 311 to an adjustable structure, the distance between each upper roller 311 and the lower roller group 32 can be changed individually. The adjustment block 2412 is slidably adjusted and set in the arc groove 2411, and the adjustment block 2412 is matched with the adjustment screw rod 2413. When the adjustment screw rod 2413 is rotated, the height position of the adjustment block 2412 in the arc groove 2411 is changed, so that the height of the upper roller 311 rotatably connected to the adjustment block 2412 is changed. The hardness of the plate strip can be changed individually for each upper roller 311.

[0032] Please refer to Figure 1-Figure 2 As shown, the upper roller group 31 includes a plurality of upper roller shafts 311, and the plurality of upper roller shafts 311 rotate synchronously through a transmission belt 33.

Both ends of the guide rollers 21 are rotatably connected to the support platform 2. The guide rollers 21 provide guidance for the plate unwound by the uncoiler 1.

[0037] Working principle of this utility model:

[0038] The plate is unwound by the uncoiler 1 and transported to the side of the support platform 2 under the guidance of the guide roller 21;

[0039] The plate passes between the upper roller group 31 and the lower roller group 32. The upper roller shaft 311 in the upper roller group 31 rotates, and a plurality of upper cutting rollers 312 are fixed on the upper roller shaft 311. The lower roller shaft 321 in the lower roller group 32 rotates in the direction opposite to the upper roller shaft 311. A plurality of cutting grooves 322 are fixed on the lower roller shaft 321. The positions of the upper cutting rollers 312 and the cutting grooves 322 correspond one to one, so that the plate passes between the upper cutting rollers 312 and the cutting grooves 322 to be cut into strips.

[0040] The slit sheet material is conveyed to the cutting device via the conveyor belt 23 for cutting;

[0041] The cut sheets are finally unloaded via conveyor belt 23;

[0042] Among them, the upper roller group 31 and the upper roller shaft 311 in the upper roller group 31 can be adjusted. The adjustment principle of the upper roller group 31 is as follows: straight slots 24 are opened at both ends of the support cover 22, and a movable plate 241 is provided in the straight slot 24 which can be adjusted up and down. The movable plate 241 is equipped with a screw rod 242. The rotation of the screw rod 242 is driven by manually rotating the hand wheel 243. The screw rods 242 at both ends of the support cover 22 are rotated by rotating the hand wheel 243. While rotating, the screw rods 242 cooperate with the movable plate 241 to change the position of the movable plate 241 along the height direction of the straight slot 24, thereby changing the position of the upper roller group 31. The distance between the roller group 31 and the lower roller group 32 changes to adapt to plates of different thicknesses; the adjustment principle of the upper roller shaft 311 is: an arc groove 2411 is opened on the movable plate 241, and an adjustment block 2412 is provided in the arc groove 2411 which can be adjusted up and down. The adjustment block 2412 changes the height by adjusting the rotation of the screw rod 2413 to individually change the distance between one of the upper roller shafts 311 and the lower roller group 32. When the height of the individual upper roller shaft 311 changes, the tensioner 313 can ensure the tension of the conveyor belt 23 to ensure the normal operation of the upper roller group 31.
