Description

Multi-blade band saw
Technical field
The utility model relates to a kind of band sawing machine, relates in particular to a kind of multi-blade band saw.
Background technology
Existing band sawing machine has only a pair of saw wheel usually, and a saw blade is installed, and is used for forming a saw kerf on timber, and its sawmilling efficient is lower.In order to solve the problem of sawmilling inefficiency, a kind of many saw blades circular sawing machine appears again in the market, this saw can once form a plurality of saw kerfs on timber, be partitioned into polylith timber, its sawmilling efficient is than higher, but because saw blade is limited by intensity, its thickness is thicker, swage set is wasted timber than broad, and timber utilization rate is lower.
The utility model content
The purpose of this utility model is to provide a kind of sawmilling efficient height, swage set narrower, can save timber, improve the multi-blade band saw of timber utilization rate.
For this reason, multi-blade band saw of the present utility model, comprise up and down saw wheel, up and down saw wheel supporting seat and be arranged at saw blade strainer between the up and down saw wheel supporting seat, described up and down saw wheel is at least two pairs, wherein the first upper wheel axle of first pair of up and down saw wheel and first time saw wheel axle are major axis, other each to up and down saw wheel axially being arranged in order along the first saw wheel axle, and its upper wheel axle and following saw wheel axle are hinged with the described first upper wheel axle and first time saw wheel axle respectively by the last connecting rod and the lower link of equal in length, form at least one four-bar mechanism around the described first upper wheel axle and first time saw wheel axle swing, swinging end at described lower link is hinged with support bar, the other end of this support bar is articulated on the support, is provided with the support bar length adjustment device in the middle of the support bar.
Because adopt bands for band as cutting tool, saw blade is thinner, the cutting swage set is narrow, can effectively save timber, improves the utilization rate of timber; At least two pairs of saw wheels are set at least two bands for bands can be installed, form at least two swage sets simultaneously, improve sawmilling efficient; Upper wheel axle and following saw wheel axle are hinged with the described first upper wheel axle and first time saw wheel axle respectively by the last connecting rod and the lower link of equal in length, form at least one four-bar mechanism around the described first upper wheel axle and first time saw wheel axle swing, make at other each saw blade keeping parallelism to installing on the saw blade installed on the saw wheel and the first pair of saw wheel, the assurance swage set is parallel, and, can regulate the distance between the swage set by regulating the length of support bar; Other each to up and down saw wheel along axially being arranged in order of the first saw wheel axle, saw blade is cut in the timber successively, reduce the cutting resistance of timber.
