Description
Technical field
The improvement of feed mechanism type of drive is fed the present invention relates to a kind of woodworking machinery, more particularly to means of woodworking longitudinal sawing machine.
Background technology
Means of woodworking longitudinal sawing machine is the woodworking machinery for carrying out ripping to timber by circular saw bit rotary motion, and carpenter indulges
Saw mainly includes the machineries such as multi-disc Vertical sawing machine, sawing machine and straight-line trimming Vertical sawing machine；By sawing timber quilt during work
Be pressed on feeding carrier bar, and with feeding carrier bar is slided along its guide rail make timber feeding feeding, timber push to saw blade with
Complete the ripping to timber；The saw cutting speed direction of saw blade and feeding feed direction in this feeding, sawing process
Conversely, timber is by the sawing of saw blade institute under the dragging effect of feeding carrier bar.
Existing means of woodworking longitudinal sawing machine, such as multi-disc Vertical sawing machine, the feeding carrier bar of sawing machine use track structure mostly,
The endless strand being made up of several end to end chain Slab elements is slidably supported on support work top, in feeding carrier bar
Top is provided with nip rolls, and be pressed in timber on feeding carrier bar by nip rolls, is driven by carrier bar and realizes feeding feeding.It is existing this
Plant in feeding clamp structure, driving that pressure roller is unpowered is simply passively compressed and acts on timber upper side, and timber is only arrived
From the effect of the admission motive force of lower section feeding carrier bar.But with means of woodworking longitudinal sawing machine process velocity, cutting-rate and processing
The raising of required precision, this carrier bar one side effect seems not enough to the drag force of timber, particularly when Wood surface is concavo-convex not
It is flat or when distorting, chain plate surface and the contact area between timber and contact fastness and can significantly reduce, it is easy to during carrier bar feeding
Causing timber can not only occur to be skidded along the transverse direction of feed direction with respect to the skidding of carrier bar, and this skidding, can also cut open
The torsion and longitudinal direction for cutting timber are skidded, and cause timber to clamp even stuck saw blade, saw blade speed is declined or can not be had
Effect sawing, has a strong impact on cutting-rate, and the damage of saw blade can be also caused when serious.
The content of the invention
For deficiencies of the prior art, the technical problems to be solved by the invention are to provide a kind of with stabilization
