Description

Convex disc cutter

Technical Field

The utility model belongs to the technical field of the cutter, more specifically say, relate to a protruding disc sword.

Background

The circular knife is one of the important parts of the splitting machine. The choice of slitter blades is generally determined by the type and thickness of the slit material. The slitting patterns of the slitting machine blades generally include square-blade slitting and circular-blade slitting. The cutting of the circular cutter mainly comprises two modes of cutting by an upper circular cutter and a lower circular cutter and extruding-type cutting by a circular cutter. The cutting with the circular cutter is the main cutting mode for cutting thick films, composite thick films, paper and other materials. The extrusion type cutting mode of the circular cutter can cut thin plastic films, thick paper, non-woven fabrics and the like, and is a convenient cutting mode.

Several patents have been disclosed in the art of disc cutters, such as the flat disc cutter shown in fig. 1, for example, chinese patent No. 201510401721.8 discloses a slitting disc blade; chinese patent No. 201510401724.1 discloses a slitting disc cutter; chinese patent No. 201510401724.1 discloses a slitting disc knife or the like. However, for some special products, a novel convex disc cutter needs to be designed for cutting so as to meet the use requirement.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 2 to 3, the convex disc cutter of the present embodiment includes a cutter body 100, a mounting hole 110 is formed in the center of the cutter body 100, the cutter body 100 is sleeved on a cutter shaft through the mounting hole 110, a cutting edge 120 is formed on the circumferential edge of the cutter body 100, the cutting edge 120 may be formed by means of laser cutting, machine tool grinding, etc., and the central portion of the cutter body 100 is bulged upward to form a convex surface 130. Compared with the flat disc cutter structure in the prior art, the central part of the cutter body of the embodiment is bulged upwards to form a circular convex surface, so that for some products needing cutting angles, on one hand, cutting can be completed quickly; meanwhile, the blades are distributed on the cutter shaft at intervals, the round convex surface 130 and the spacer bush are mutually abutted, axial acting force is generated, the blades can be effectively prevented from shaking, and cutting is more stable.

On the basis of the above structure, the circular convex surface 130 is an inclined plane, the inclination is 3 to 5 °, and the inclination of the inclined plane may preferably be 5 °. In addition, the convex surface 130 may be an arc surface with an arc of 3-5 °.
