[0002] In the prior art, the S-type rubber four-roller calender is the key equipment for producing large-scale mine conveyor belts. It directly promotes the localization process of large-scale mine transportation in China. The cutter on the conveyor belt calender has always been a problem. In the past, the cutter After the top and bottom glue is applied, the excess part is cut off based on the edge of the belt core, and the maximum thickness of the conveyor belt core can reach 30mm. After the glue is attached, the thickness can reach 50mm, because the cutter cannot be positioned accurately , often cut to the belt core, but the thickness of the belt core is too thick, most of the material is very hard, the cutter cannot work, and the edge cutting effect is very bad

Embodiment Construction
[0010] Such as figure 1 and figure 2 As shown, the automatic cutter for the calender includes a blade 1, a knife rod 9, a cylinder 2, a linear bearing 3, a bracket 4, an infrared detection device 5, an electric push rod 6, a hand wheel 7 and a positive and negative screw rod 8, the blade 1 is installed on the front end of the cutter rod 9, the cylinder 2 is installed on the cutter rod 9, the linear bearing 3 and the infrared detection device 5 are installed on the bracket 4 respectively, and the electric push rod 6 is connected to the forward and reverse screw rod 8 through the connecting plate 10. At one end, the handwheel 7 is installed on the other end of the positive and negative screw rod 8. When working, when the upper film A passes through the gap between the 1# roller and the 2# roller, the lower film B passes through the gap between the 3# roller and the 4# roller. Before the film with a certain thickness is pasted on the belt core C, the infrared detection device 5...

The invention discloses an automatic cutter of a calender. The automatic cutter comprises blades, cutter rods, air cylinders, linear bearings, a support, an infrared detecting device, an electric push rod, a hand wheel and a double-way screw rod. The blades are mounted at the front ends of the cutter rods, the air cylinders are mounted on the cutter rods, the linear bearings and the infrared detecting device are respectively mounted on the support, the electric push rod is connected to one end of the double-way screw rod via a connecting plate, and the hand wheel is mounted at the other end of the double-way screw rod. When an upper rubber sheet and a lower rubber sheet are not attached to a belt core, extra rubber edges of the rubber sheets relative to the belt core are cut off by the aid of the automatic cutter of the calender. When in use, position of the belt core is detected by the infrared detecting device automatically, signals are sent to the electric push rod which accurately positions the upper rubber sheet and the lower rubber sheet, and then the extra rubber edges are cut off. Perfect centering attachment between the rubber sheets and the belt core are guaranteed, quality of the rubber products is guaranteed, and functions of the cutter are realized. The automatic cutter of the calendar is novel, compact and reasonable in structure.
