Double-cutter disc cutting machine and control method thereof

Abstract

The invention discloses a double-cutter disc cutting machine and a control method thereof, and belongs to the technical field of stone machining mechanical equipment. The double-cutter disc cutting machine comprises a rack, a track, two circular saw blades arranged on the two sides of the track and a control main body used for controlling the circular saw blades to rotate, wherein the rack comprises two stand columns which are arranged on the track in a front-back mode and are perpendicular to the track, the two control bodies are installed on the stand columns in the direction parallel to the track, and a first lifting device and a second lifting device which are used for controlling the two control bodies to ascend and descend respectively are fixedly installed on the stand columns; the control method comprises the following steps: starting a cutting machine, and adjusting the circular saw blades to designated transverse positions; setting a cutting mode of the cutting machine, and starting cutting; after cutting is completed, keeping the saw blades rotating continuously, and lifting the saw blades to complete one-time cutting operation. The double-cutter disc cutting machine has the beneficial effects that by controlling the rotating speed of the saw blades and the lifting speed of the saw blades, the saw blades are not prone to being broken, and the working efficiency is not affected.

Description

technical field [0001] The invention relates to the technical field of stone processing machinery and equipment, in particular to a double-knife disc cutting machine and a control method thereof. Background technique [0002] Existing mines have widely used mining and quarrying machinery for mining stone materials. From the initial single saw machine with a single saw blade to the development of a single saw machine with multiple saw blades at both ends of the main shaft, the quarry machine is becoming more and more popular. It is convenient and the quarrying efficiency is gradually improved. However, the properties of the stones mined by the current quarrying machines are not exactly the same during the mining process. The stones in a certain part of the mine may have higher or lower hardness than the stones in another part. At this time, when the saw blade cuts the stones Stones with different hardness will have different resistance effects. During the cutting process, th...

Problems solved by technology

[0004] In order to overcome the existing stone quarry in the prior art, the hardness of a certain part of the stone in the mine mined by the quarry may be higher or lower than that of another part during the mining process, and the existing quarry cannot cut the stone in the cutting process. Adjusting the rotation speed of the saw blade and the feed movement in the downward direction may easily cause the saw blade to break and reduce the working efficiency during operation.
