Embodiment Construction

[0020] A slitting device with a width of 250mm is used as an example to describe in detail, but it does not limit the scope of protection.

[0021] The slitting tool assembly is composed of a knife holder 1, a knife roller 3 with 4 sets of round knives 2 preset, a support roller 4 and a material rack 6, and the knife roller 3, material rack 6 and support roller 4 are fixed in parallel in sequence from bottom to top. On a pair of parallel vertical tool holders 1, the structure of the tool assembly is as attached figure 2 shown.

[0022] The tool holder 1 is composed of two parallel square steels with a distance of 250 mm, and the bottom end is provided with an installation structure matching the cutting equipment;

[0023] The support roller 4 is a nylon roller with a diameter of 100mm and a width of 200mm, and the surface is centered and circumferentially uniformly distributed with 4 groups of grooves 5 with a width of 6mm and a depth of 4mm, and the center interval is 50mm;...

Abstract

The invention belongs to the technical field of sheet machining. A principle of a motor driving a circular cutter to mechanically cut is adopted to solve the problems of low self-adhesion performance of self-adhesion damping rubber sheets and low slitting efficiency, so that the purpose of efficient slitting of coils of the self-adhesion damping rubber sheets is realized. A slitting cutter assembly comprises cutter frames (1), circular cutters (2) mounted on a cutter roller (3), and a support roller (4); and a transmission mechanism drives cutting edges of the circular cutters (2) to be in the direction opposite to the material operation direction. The slitting cutter assembly has the advantages that cutting surfaces are smooth, the slitting efficiency is high and, the wear of the circular cutters is low, and is suitable for sheet slitting, and in particular, suitable for slitting of the coils of the self-adhesion damping rubber sheets.

Description

technical field [0001] The invention belongs to the technical field of sheet material processing, and relates to the cutting technology of wide coils, in particular to the cutting tool technology. Background technique [0002] Damping technology loses mechanical energy through the shearing and tension-compression deformation of the damping layer, and reduces the resonance and noise of the structure. It is widely used in ships, aircraft, automobiles, machinery and other fields. Self-adhesive damping film is a rubber-based polymer material. It is used as a damping layer and a constrained layer to form a constrained damping structure. It is pasted on the surface of the shell component with severe vibration, and has a significant vibration and noise reduction effect. [0003] The currently used self-adhesive damping film coil is processed by molding, extrusion and other processes from mixed rubber. Its width is 180mm. Narrow strips, this cutting process has the problems of low ...
