Full-automatic bilateral upper and lower shaft multi-blade woodworking sawing machine

Abstract

The invention relates to a woodworking machine, and provides a full-automatic bilateral upper and lower shaft multi-blade woodworking sawing machine which is reasonable in structural design and high in sawing accuracy. The distance between saw blades is adjustable and can be relatively adjusted according to the diameter of different raw wood, the use value of the raw wood is high, raw materials are slightly wasted, and boards of various specifications can be processed according to the actual requirement. The machine comprises a machine body, left and right spindle boxes which are respectively arranged on the two longitudinal sides of the machine body and can longitudinally slip along the machine body, and left and right saw shaft assemblies rotatably arranged on the left and right spindle boxes, wherein each of the left and right saw shaft assemblies comprises an upper saw shaft and a lower saw shaft which are respectively arranged at the upper and lower positions of each of the left and right spindle boxes; the same number of saw blade groups are arranged on each independent upper saw shaft and lower saw shaft; each saw blade group comprises a first saw blade, a second saw blade and a combined saw blade; and distance adjusting devices for adjusting the distance between the first saw blade and the second saw blade and the distance between the second saw blade and the combined saw blade are respectively arranged on each upper saw shaft and each lower saw shaft.

Description

technical field [0001] The invention relates to a woodworking machine, in particular to a fully automatic double-side up-down axis multi-piece woodworking sawing machine. Background technique [0002] Double-sided upper and lower axis multi-piece woodworking sawing machine is currently the main production equipment widely used in sawing woodworking materials. It is a sawing equipment for sawing logs into sheet-like plates of a certain thickness for further processing into products. [0003] Such as figure 1 , the existing multi-piece woodworking sawing machine with double-sided upper and lower shafts generally includes a bed 1', a left headstock 11', a right headstock 12', a left saw shaft assembly, a right saw shaft assembly, and the left and right main shafts Boxes 11' and 12' are symmetrically arranged on both longitudinal sides of the bed 1, and are arranged on the guide rail 13' of the bed 1' that can be moved longitudinally inward or outward by the drive motor 2', and...

[0003] like figure 1 , the existing multi-piece woodworking sawing machine with double-sided upper and lower shafts generally includes a bed 1', a left headstock 11', a right headstock 12', a left saw shaft assembly, a right saw shaft assembly, and the left and right main shafts Boxes 11' and 12' are symmetrically arranged on both longitudinal sides of the bed 1, and are arranged on the guide rail 13' of the bed 1' that can be moved longitudinally inward or outward by the drive motor 2', and the left saw shaft assembly is installed On the left headstock 11', the right saw shaft assembly is installed on the right headstock 12', and the left and right saw shaft assemblies respectively include an upper saw shaft 3' and a lower saw shaft 4', and the upper and lower The saw shafts are respectively installed at the upper and lower positions of the left and right spindle boxes at a certain angle staggered from front to back. Each independent upper and lower saw shafts are equipped with the same number of saw blade groups 5', and the upper and lower relative saw blade groups 5' 'Installed on the same vertical plane, the ends of the upper and lower saw shafts away from the saw blade group extend outwards and pass through the left and right spindle boxes respectively, and are driven by the motor through the pulley 6' and the belt. The above-mentioned traditional The woodworking sawing machine can only adjust the distance between the outermost saw blade 51A' on the left saw shaft assembly and the outermost saw blade 51B' on the right saw shaft assembly by adjusting the longitudinal distance between the left headstock 11' and the right headstock 12'. The distance between the saw blades on the left and right saw shaft assemblies is relatively fixed and cannot be adjusted. In actual use, it is impossible to make relative adjustments according to the size and shape of different logs, and it is impossible to saw the best log. The location of the sawing road and the low cutting precision cannot make the best use of wood, resulting in waste of raw materials and reducing the use value of logs, and can only be cut according to the size set by the machine tool, and cannot be processed according to actual needs. Plates with standard plate thickness cannot meet the needs of production, and the production cost is high
