Abstract

A cutter for rubber driving belt forming relating to the rubber machinery consists of a base (1), a main drive device (2), a film unrolling device (6), a cord unrolling device (7), a building drum (3), a tailstock (4), a black board box (5), and a space included angle formed by disc knives (46)(47) arranged on the upper and lower parts of a black board box support, wherein the building drum contains an expansion drum. To carry out modern rubber V belt cutting is mainly like that: the disc knives which form the space included angel are used to cut the two side faces of a raw rubber belt barrel, and the expansion drum which is an auxiliary appliance for cutting V belt is used to fix the raw rubber belt barrel. The rubber V belt produced by the equipment has the advantages of high driving power, long service life, reduced labor intensity, and high rate of products meeting standards. The forming and cutting of the rubber driving belt can both be completed by the equipment.
