Problems solved by technology

The edge of the upper knife is relatively thin, and the pulling of the sheet can only slightly drive the rotation of the upper knife. The rotation of the upper knife is mainly transmitted by the friction between the lower knife and the edge of the upper knife.

Abstract

The invention discloses a disc cutter trimming mechanism of a sheet extrusion machine. The mechanism comprises a lower disc cutter, a first rotating shaft, an upper cutter base, an upper cutter base positioning mechanism, an upper disc cutter, a second rotating shaft, a lower cutter base and a lower cutter base positioning mechanism, and is characterized in that an upper cutter acceleration mechanism is mounted on the upper cutter base, wherein a sheet following ring drives the upper disc cutter to rotate through a gear acceleration mechanism; and the gear acceleration mechanism enables the rotating linear velocity of the upper disc cutter to be quicker than the rotating linear velocity of the lower disc cutter. Compared with the prior art, the mechanism has the following beneficial effects: as the upper cutter acceleration mechanism is arranged, sheets are pulled to effectively drive the lower cutter and the upper cutter to rotate, the rotating linear velocity of the upper cutter is quicker than the passing linear velocity of the sheets, and the cutting of the cutter is facilitated; and the mechanism is simple in structure and excellent in use effect, effectively eliminates the slip phenomenon, and prevents the condition of incapability of cutting off the sheets due to no rotation of the upper cutter.

Description

technical field [0001] The invention relates to a sheet material trimming mechanism of a sheet extruding machine, more specifically to a disc cutter edge trimming mechanism of a sheet extruding machine. Background technique [0002] Extruded sheet production lines generally need to trim both ends of the sheet. At present, extruded sheet machines usually use a scratch knife or a disc cutter to trim the edges. [0003] The structure of the scratching knife is simple, but the cutting edge needs to leave a wider edge to cut, which will cause a large waste of material. [0004] The disc cutter is composed of an upper knife and a lower knife (such as figure 1 As shown), the upper knife and the lower knife rotate to cut off the sheet entering the knife edge. The sheet material entering the knife edge is in contact with the top surface of the lower knife. When the sheet material is pulled and passes through the knife edge, the sheet material drives the lower knife to rotate. Sinc...
