An automatic slitting machine, wherein the slitting machine comprises a machine frame, an unwinding device, a slitting device, a shaft return device, a transmission device and a winding device;
- wherein the unwinding device comprises an unwinding frame and an unwinding shaft;
- the unwinding shaft is mounted on the unwinding frame, and the unwinding shaft is configured for mounting a parent roll;
- the rotation of the unwinding shaft drives the parent roll to release adhesive paper;
- the slitting device comprises an upper circular cutter and a lower circular cutter;
- one side of the machine frame is a slitting region, the upper circular cutter and the lower circular cutter are both provided in the slitting region;
- the upper circular cutter sheathes and fixes a plurality of slitting cutters;
- the slitting cutters are tangent to the lower circular cutter, and the adhesive paper passes between the slitting cutter and the lower circular cutter;
- the shaft return device comprises a transverse moving seat, a shaft return chain, a guide rod and a push plate, wherein one side of the machine frame is a shaft release region;
- the transverse moving seat moves linearly with respect to the shaft release region and the slitting region;
- the shaft return chain moving synchronously and in the same direction is provided at both sides of the shaft release region;
- an edge of the transverse moving seat is engaged with the shaft return chain, and the height of the transverse moving seat is lower than an upper part of the shaft return chain;
- a limiting member is fixed in the shaft return chain by several links;
- two ends of a winding shaft are respectively placed between two adjacent limiting members corresponding to two of the shaft return chains, moving the winding shaft to the transverse moving seat with the running of the shaft return chain;
- the guide rods are fixed on both sides of the slitting region;
- the guide rod is provided in an inclined manner, and the upper end of the guide rod is engaged with the edge of the transverse moving seat;
- the lower end of the guide rod is recessed downwards to form a limiting groove;
- the winding shaft in the transverse moving seat sliding down the guide rod to the rotating shaft at the two ends thereof is respectively caught in the limiting groove of the two guide rods, and the push plate moves relative to the limiting groove to push out the winding shaft located in the limiting groove;
- the transmission device comprises a moving seat and a driving shaft;
- the driving shaft is connected to the moving seat, and the driving shaft rotates relative to the moving seat;
- a spline hole is provided on the axis of the driving shaft;
- the moving seat is located on a side edge of the slitting region and moves relative to the guide rod, and moves until the spline hole is fitted outside a first spline at an end of the winding shaft;
- the winding device comprises a flat insert plate, a breaking blade and an inclined insert plate, wherein the flat insert plate is close to a lower end of the guide rod, and the flat insert plate moves horizontally above the limiting groove;
- the breaking blade is located above the flat insert plate after being reset, and the breaking blade moves vertically and parallelly to the flat insert plate;
- the inclined insert plate is provided obliquely above the limiting groove;
- and the inclined insert plate moves along an inclination angle thereof relative to the limiting groove.
