Description

Technical Field

[0001] The present application relates to the field of mechanics, and in particular to a multi-wire magnetic suspension tension regulator. Background Art

[0002] At present, the multi-wire cutting machine technology uses the reciprocating motion of the diamond wire to cut hard and brittle materials. The main cutting materials are ceramics, sapphire crystals, silicon crystals, marble, magnetic materials, etc. The diamond wire is repeatedly wound by multiple sets of rollers to form multiple cutting lines, and the tension of each line must be uniform. Therefore, a tension regulator is needed to adjust the tension of the diamond wire. The tension adjustment technology currently used is mainly a swing arm tension regulator controlled by a servo motor. The main problem is uneven tension adjustment, which causes the diamond wire to break frequently during use.

[0003] In the marble cutting process, due to the large volume of marble, each diamond cutting wire needs to be more than 3 meters long, and usually 150 windings are required. Such a long diamond wire generates a lot of friction when it passes through four rollers, and then enters the pay-off wheel or take-up wheel through the tension regulator. The tension is difficult to adjust to be constant, so we proposed a multi-wire magnetic suspension tension regulator. Utility Model Content

[0004] The present application provides a multi-wire magnetic suspension tension regulator to solve the above-mentioned problems.

[0005] The present application provides a multi-wire magnetic suspension tension regulator, including diamond wires, which are staggered and overlapped on roller driven rollers and roller active rollers, and the diamond wires are also overlapped on the magnetic suspension tension regulator. The magnetic suspension tension regulator includes a bracket, a fixed magnet, a rotating shaft bearing, a guide wheel magnetic ring and a guide wheel. The fixed magnet and the guide wheel magnetic ring are each provided with a plurality of them, and the fixed magnets and the guide wheel magnetic rings are staggered, and the magnetic poles of the opposite surfaces of the fixed magnets and the guide wheel magnetic rings are the same. The outer side of the guide wheel magnetic ring is fixedly sleeved on the guide wheel, and a plurality of the diamond wires are correspondingly overlapped on each of the guide wheels, and a plurality of groups of guide wheels form a plurality of independent magnetic suspension tension adjustment mechanisms.

[0006] Preferably, a connecting circular hole is opened on the front side of the bracket, the interior of the connecting circular hole is fixedly connected to a fixed magnet, and a rectangular hole is also opened in the middle of the fixed magnet.

[0007] Preferably, a rotating shaft bearing is fixedly connected to the middle of the guide wheel magnetic ring, a rotating shaft is fixedly inserted into the middle of the rotating shaft bearing, and the rotating shaft is movably inserted into the rectangular hole.

[0008] Preferably, a groove is formed on the outer side of the guide wheel.

[0009] Preferably, the bracket connecting end of the magnetic suspension tension regulator is fixedly connected to the supporting frame.

[0010] Preferably, the middle parts of the roller driven roller and the roller active roller are fixedly plugged with a main shaft, and the main shaft is plugged into the support frame through a bearing.

[0011] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0012] In the structure provided by the embodiment of the present application, the upper ends of the multiple guide wheels of the magnetic levitation tension adjuster are respectively overlapped with a diamond wire. Since a guide wheel magnetic ring is provided between two fixed magnets, the repulsive force between the fixed magnets will push the guide wheel magnetic ring to move outward. Since the plug-in hole of the rotating shaft is rectangular, the rotating shaft can be displaced inside the rectangular groove, so that the diamond wire has space to buffer the displacement, thereby effectively avoiding the diamond wire from breaking due to excessive tension and effectively protecting the diamond wire.
