Automatic saw teeth grinding device of band saw

Abstract

The invention discloses an automatic saw teeth grinding device of a band saw. The automatic saw teeth grinding device comprises a working framework for supporting and driving the band saw to rotate, a power device for providing power for the whole equipment, and a grinding system which is arranged in the working framework and is provided with a sand wheel and a sand wheel driving motor, wherein the grinding system is connected with a power shaft of a driving device through a warped rod, the middle part of the warped rod is movably arranged on the working framework through a bearing block, the power shaft is provided with an eccentric wheel, one end of the warped rod is positioned below the eccentric wheel, and the other end of the warped rod is connected with the grinding system through a push rod. The automatic saw teeth grinding device has the beneficial effects that the power converting effect is improved by utilizing a lever mode to drive the grinding system to work; the grinding system is separated from the power device when the band saw is not subjected to a grinding working procedure, so that idle work is prevented from being made.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a device capable of automatically grinding teeth of a woodworking band saw. Background technique [0002] In the prior art, some wood processing places such as lumber mills and furniture factories use band saws to carry out preliminary processing of wood, such as sawing logs into lengths and widths of specified sizes, and the band saws are generally ring-shaped and made of metal materials The ring belt structure with a certain width has a certain flexibility and can be hung on two rollers and rotate with the rotation of the rollers. One side of the band saw is a sawtooth cutting edge and the other side is smooth light edge. When in use, the band saw is installed on the two rollers of the band saw machine, and the motor drives the rollers to rotate to drive the band saw to rotate, and then push the log to the cutting edge of the band saw according to the line to be cut, and the log is co...
