Description
Technical field
The utility model relates to a kind of means of woodworking longitudinal sawing machine, relates in particular to the backstop device structure that means of woodworking longitudinal sawing machine prevents that timber from rebounding.
Background technology
Be widely used the means of woodworking longitudinal sawing machine tool of the series such as straight-line trimming Vertical sawing machine, automatic single Vertical sawing machine and automatic multi-disc Vertical sawing machine in timber processing industry.Sawing direction while work due to means of woodworking longitudinal sawing machine saw blade, advance the direction of feed of timber contrary, and saw blade tangential velocity is often up to 75 meter per seconds with operator.Therefore, in actual timber sawing process, inevitably occur that sawing finished product timber, particularly seamed edge material are by reverse attack, and directive operator usually causes the even serious accident such as casualties of device damage.
The comparatively general means of woodworking longitudinal sawing machine with anti-bounce-back stop device on market, is, above the upper fixed seat front end that timber pressure roller and rotating saw blade are installed, timber conveyer belt, stop device is housed actively, and when timber is backward when feeding, upper stop device is lifted; When timber is subject to the reverse attack of saw blade and when counter motion, because the non-return claw of upper stop device is only to swing within the specific limits, thereby stoping timber reverse movement forward, upper stop device plays safeguard protection effect.But the anti-rebounding device of this structure, contact with the collision of upper stop device for fear of conveyer belt on the one hand and damage parts, between upper stop device pawl end and conveyer belt (or work top), still need to leave larger gap, be less than the reverse of this gap thickness timber and launch thereby can not stop; On the other hand, in the time of timber sawing surface imperfection, the stop device that is positioned at timber top is often surprisingly lifted, and does not have non-return effect; In addition stop device can not stop seamed edge material to fly out from the side.Therefore, this structure can not be stopped the generation of the human casualty accident that the reverse ejection of timber causes completely.
In order to overcome the deficiency of traditional anti-bounce-back backstop, the applicant once disclosed a kind of utility model patent " backstop of means of woodworking longitudinal sawing machine ", this backstop is except stop device is being installed above workbench, stop device under also installing on workbench, stops the bounce-back of timber in sawing process by the double action of upper and lower stop device.Although the security performance of the anti-bounce-back backstop of this structure is greatly improved, but still deposit not enough both ways: the one, the gap existing between adjacent upper stop device monodactyle still likely becomes the passage that timber seamed edge material oppositely launches, especially the out-of-flatness of Wood surface causes adjacent upper stop device to lift the inconsistent of angle, gap between adjacent upper stop device is strengthened, and added the probability of log bounce-back.Timber is in feeding process on the other hand, especially leave in the feed distance of stop device, feeding timber loses the anti-rebound effect of stop device completely, timber is under the high speed sawing effect of saw blade, still there is the possibility of oppositely launching, and existing upper stop device to the anti-bounce-back effect of wider timber a little less than, can not stop oppositely launching of timber completely, still there is certain potential safety hazard.
Utility model content
For the existing deficiency of above-mentioned prior art, technical problem to be solved in the utility model is to provide and a kind ofly can effectively stops sawing timber bounce-back, the safe and reliable anti-bounce-back safety device of means of woodworking longitudinal sawing machine.
In order to solve the problems of the technologies described above, the anti-bounce-back safety device of means of woodworking longitudinal sawing machine of the present utility model, comprise workbench, lower stop device is housed on this workbench, stop device is housed on the holder above workbench, wide stop device is also housed on holder, and this wide stop device is adjacent with upper stop device position; Above described workbench, be also provided with cambered surface stop device, this cambered surface stop device is positioned at the front side of saw blade.
In said structure, owing to being adjacent to be provided with upper stop device and wide stop device on holder, it is wide or while being staggered installation of that wide stop device monodactyle and upper stop device monodactyle do not adopt, both single inter-claw spaces are reported to the leadship after accomplishing a task to be blocked, thereby has stoped sawing timber seamed edge oppositely to launch from its gap.Again owing to being provided with cambered surface stop device above workbench, this cambered surface stop device is positioned at the front side of saw blade, the cambered surface stop device of installing that leans forward acts on feeding timber, makes again the whole timber can not feed reversing or oppositely launch, and can only do feed motion along workbench.Also, due to the double action of upper stop device and lower stop device, the timber of any thickness or seamed edge material all can not reversely be launched, can only be close to conveyer belt or work top feeding, side guard shield has stoped again seamed edge timber to fly out from the side simultaneously.Therefore the utlity model has the multiple anti-reverse effect of launching, effectively stop oppositely launching of sawing timber, use more safe and reliablely, fully guaranteed the safety of the person and equipment.
A kind of preferred embodiment of the present utility model, described upper stop device is formed by the horizontal closed assembly of some sheet pawls, and described wide stop device also formed by the horizontal closed assembly of some laminar pawls.The monolithic non-return claw width of described wide stop device is greater than the monolithic non-return claw width of stop device.This structure is effectively blocked the gap between the monodactyle of wide stop device and upper stop device, and the seamed edge material of any thickness all can not reversely be launched.
Another preferred embodiment of the present utility model, the front end of described cambered surface stop device is arcwall face, is provided with non-return tooth on this arcwall face.Between the cambered surface stop device in this structure and feeding timber, there is powerful reliable friction force, can stop the reverse movement of timber completely.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the anti-bounce-back safety device of the utility model means of woodworking longitudinal sawing machine is described in further detail.
