Description
Technical field:
The present invention relates to the woodworking machinery technical field, is the full-automatic endless finger joint machine of a kind of vertical box pin joint of big section timber lath specifically, is used for the veneer that the integrated timber production and processing uses or the continuous spreading special equipment of big section timber structure beam column edge-gluing veneer; Be particularly suitable for the processing of big section timber buildings manufacture of materials, length dimension changes arbitrarily to be set, and linear measure longimetry is accurately consistent, and automaticity height, cost be low to be fit to all kinds of large, medium and small scale enterprise.
Background technology:
Along with the raising of economy and living standards of the people, people have proposed the requirement of " the green inhabitation " to the environment of depending on for existence, will be soon inhabitation targets based on the modern wood structure building construction of engineered wood prepared material.But because the over-exploitation of forest and the enforcement of global wildwood protected project, big footpath level log constantly reduces and price stiffened, consumes wood structure from every profession and trade, and furniture manufacturing industry can be converted to that to consume small dimension wood be main from consuming big footpath material fully.The forest intermediate cutting makes the small dimension wood surplus, big footpath material is in short supply, in order to utilize artificial forest wood, thinnings, brush wood fully, and path softwood especially, alleviate forest decay and solve the timber imbalance between supply and demand, in order to reduce pressure, reach the big usefulness of small wood, the purpose of the excellent usefulness of bad material, people have begun the recycling research of timber, promptly utilize small wood, tailing two ends mill teeth, carry out finger again, make furniture with integrated timber or structure material for building.Timber structure is recycling as renewable resource, be spliced into column, bow beam integrated timber through reprocessing raising stress, fire prevention, anticorrosion, mothproof processing, obtain bigger development and use in developed country, generally be used for large stadiums such as recreation ground, grand theater, stadium, library, can have substituted the reinforcing bar cement structures fully, it is having significant advantage aspect fire-protection rating, shock strength, comfortable safety, the low-carbon economy.
At present domestic finger joint machine commonly used (also have be called grafting machine) is various in style, different, and semi-automatic branch is automatically arranged on the performance, and specification mostly is confined in 80 millimeters of 8 meters of the processing lengths, 150 millimeters of width, thickness.The processing specification is generally determined to make by contract for future delivery, operation principle is that the tooth punching gluing batten that the width and thickness equal length differs is delivered on the workbench, horizontal sliding presses horizontal press mechanism work top level to compress to having then, one end maintains static the afterburning extruding of other end oil cylinder and finishes spreading work, but can only change the buting iron position when user's production and processing length variations in its effective range realizes, the outstanding shortcoming of Cun Zaiing like this: the one, several end to end mortise battens are arranged in every section fixed length, it is when feed length reaches the buting iron position and by customized cut-off, because batten quantity uneven in length in every section is indefinite, seam quantity difference is bigger, size is uneven in length behind two ends application of force extruding spreading, need that sawing again is flush to cause waste, uniformity is poor; The 2nd because extruding force applies from an end, when big section plank is tight by the horizontal extrusion of last pressure the longitudinal pressure transmission fluctuation that is affected bigger, cause finger seam tightness degree to differ poor stability; The 3rd, owing to the limitation that length changes, can not two planks of random length of temporary needs be docked, poor for applicability; The 4th, each order specification requirement is not quite similar, and the machine overall dimension difference is bigger, and versatility is poor.
The more advanced endless finger joint machine of woodworking machinery mostly is comprehensive processing unit in the world, existing mortise mill teeth function has tenon tooth gluing function to push the spreading function in addition again, it is that the two generous identical planks that will treat spreading are sent in the middle of the lathe, two groups of clamp mechanism clamp plank respectively and make the end to keep certain distance, the mortise unit head Milling Process tenon tooth that moves both vertically then, unit head withdraws from the back to the box pin joint gluing, and two groups of clamp mechanism relative motions are closely finished spreading processing with wooden tooth extruding.But its weak point is: the one, and complexity coefficient is big, geometric accuracy height, manufacturing cost height; The 2nd, the wood chip dust discharge of mill teeth processing is not mingled with in the gluing when thorough, causes to be expressed to make seam not tight in the tenon tooth; The 3rd, fairly simple mill teeth coating process is comprehensively become complex device, stop platform probability and maintenance cost and strengthen, cause finger production efficiency not high; The 4th, when profile of tooth changes tool changing cumbersome, thereby occupation rate of market is very low very low.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and the full-automatic endless finger joint machine that provides a kind of all size, different section timber spreading to produce mainly solves problems such as existing finger joint machine production efficiency is low, crudy fluctuates greatly, the scope of application is little, popularization difference.
