Description

" Air-Uplift " pressure type veneer patcher

Technical field

The utility model relates to a kind of Pneumatic stamping machinery mended by replacing a damaged part for rounding defect of veneer.

Background technology

Usual glued board, by the odd number multilayer rotary cut venner of more than three layers, forms by the crisscross gummed of machine direction.Two face plies are called face base plate, and intermediate layer veneer is called central layer or middle plate, and face base plate and central layer, middle plate are referred to as veneer.

Face base plate is general thinner, and usual thickness, within 1mm, often selects comparatively famous and precious, the better timber rotary-cut of material to form.Along with wildwood is day by day rare, the utilization rate that famous and precious timber is used as face base plate requires to improve constantly, and the past is direct must be gradually reduced the method that defect part is all dismissed along machine direction.The natural defects such as some oil sacs on the base plate of face, little knot and tiny spot, along with the raising of glued board quality requirement, the amount of repairing also constantly increases, and a face base plate is repaired and often has even tens places of a few place.

Between the general 1.5-3.6mm of central layer (middle plate) thickness, forming as poplar, Eucalyptus rotary-cut how by fast growing wood, in recent years, fast growing wood average diameter is more and more less, bending timber with small diameter rotary-cut veneer out, the ratio of the oval hole of edge " V " font gap and centre that area is larger is inevitable more, and for improving the utilization rate of timber, the workload of single board repair is increasing.

Current veneer mainly relies on and manually mends by replacing a damaged part at home, artificial cutter cuts out with the defect part of the mode of cutting-up by veneer, and by overlap below defect of veneer, do not become the waste single boards of whole (being commonly called as burr plate), cutting-up becomes the sticking patch with cutouts same shape simultaneously, fill up in veneer, paper using adhesive tape bonding.It is large that central layer manually mends labour intensity by replacing a damaged part, and efficiency is very low.

Several veneer patcher tools of current domestic minority manufacturer production, all also exist certain use limitation.

The first is hole making drill formula veneer patcher, with can with reference to Baidu's video " automatic single-plate patching machine ", the principle of this machine, saw blade to be fixed on centered by vertical direction turning cylinder circumferentially, during use, saw blade also presses down vertically along the radial rotary of turning cylinder, is gone by the defect saw on veneer, uses the same method on other saw head, saw out sticking patch (the patch excesssive gap under same saw head saw of appropriate clearance cooperation, unavailable), manually to fill up and bonding.This method because there are burr not to be suitable for face base plate, the repairing of be only applicable to central layer worm channel, dying for the sake of honour because perforate and patch shapes be circle, for central layer edge gap, inapplicable compared with defects such as oblong holes.

The second is automatic patching machine, can with reference to Baidu's video " HWB Fully-automatic veneer patching machine ", this machine primary structure is a middle die, respectively there is the drift that a hydraulic jack drives up and down, during work, defect of veneer part is aimed at upper punch, the pressing mold parallel with the upper punch direction of motion is pushed down veneer downwards and is avoided it to move under the driving of cylinder, upper punch stamping-out defect part is also ejected die and is fallen, blown away by the blower fan normally opened, cut in advance and inserted the veneer strip of automatic delivering mechanism, be fed forward to suitable position, low punch is stamping-out upwards, sticking patch good for stamping-out is just in time delivered in the made hole of veneer, pressing mold rises, complete single board repair.

The advantage of the method that this stamping-out is repaired is that punching is repaired and automatically completes, without adhesive tape bonding.Its limitation is filled up automatically due to it on the one hand, and low punch must be plane, and its blanking pressure is much bigger compared with the blanking pressure of arcwall face drift, therefore its drift size at present maximum accomplish 150mm*90mm.This method is only applicable to central layer, because be friction tight cause, generally also can not fall down without paper self-adhesive tape is bonding.Also manually tape-stripping will be used after the mending by replacing a damaged part of the less gap of edge.Although middle long and narrow defect can overlappingly continuously be repaired, for the larger gap of edge and the oval hole of wide middle still still helpless.It is also inapplicable for the panel that Thickness Ratio is thinner, because face base plate is thin, the contact surface between sticking patch and hole is little, fills and is easy to fall down.That this machinery requirement cuts as far as possible long wide small width veneer bar in advance for stamping-out sticking patch on the other hand, burr plate can not get effective utilization, and central layer length is generally no more than 1270mm, calculate by stamping-out length 150mm, a slice veneer strip rushes 8 sticking patch, it is bonding that linking between veneer strip with veneer strip needs manually to carry out paper self-adhesive tape, affects the smooth and easy and convenient of workflow.The third aspect is because of its complex structure, and current this machine generally only has one group of punch die, at most also only accomplishes two groups of punch dies, has higher requirement to working service, and cost is relatively also costly.

The third type is hand lever punched patching machine, after completing patch and veneer punching respectively, more bonding by manually filling up blend compounds band.With reference to Baidu's video " rhombus punching veneer patcher ".Such machine operator still has certain labour intensity, and speed is fast not enough, and thicker veneer will just can sweep away several times, and by the restriction of blanking pressure, punch die can not do very large, and the scope of repairing is restricted.

Summary of the invention

In order to overcome the use limitation of existing veneer patcher, conscientiously alleviating the workload and labour intensity of manually mending veneer by replacing a damaged part, improving the popularity rate of veneer patcher tool, the veneer patcher that the utility model provides a kind of panel, central layer is all suitable for.

The technical solution adopted in the utility model is: adopt a kind of " Air-Uplift " pressure type veneer patcher, several groups of drifts and targeting part thereof are connected on upper spider, corresponding die is fixed in the upper plane of lower bearing bracket, drift is promoted by cylinder, when the two-position five-way gas circuit reversal valve of control cylinder replaces, cylinder piston rod stretches out, and drift pours die, realizes the stamping-out to veneer.Drift respectively stamping-out falls defect part and the sticking patch of the different sizes on veneer, by manually carrying out filling up and paper using adhesive tape bonding, completes single board repair.

The stamping-out face of drift is made into arc, greatly can alleviate blanking pressure, identical cylinder, and it is larger that its drift stamping-out area can do, and cylinder is less, and the speed performing piston flexible is faster.Current several bench teats test punch die minimum dimension 15*7.5 (mm) in type, maximum 350*160 (mm), can also accomplish larger if needed.The matched in clearance of die and drift controls in the less margin of tolerance, and the veneer edge that stamping-out goes out is bright and clean, does not have burr phenomenon.

For different plywood production technology requirements, in conjunction with the geometric features of defect of veneer, the drift of one or more difformities selected and size, is arranged in same frame.Drift can select olive shape, ellipse, rhombus, triangle or arbitrary shape.Particularly olive shape drift, to central layer edge " V " shape gap blanking portion length, stamping-out shape and defect close, also very close to middle slotted eye hole shape, and contraposition when pointed portion is convenient to fill up.

Because the breadth of veneer is larger, guiding can not be there is between drift and die, the utility model choice criteria ball guide pillar, do accurately to lead between cylinder and drift, for less drift two guide pillars, then use four guide pillars for larger drift, when preventing stamping-out, drift causes skew along cylinder piston rod axial rotation with because of side force.

The utility model utilizes many groups straight line laser light irradiation of being fixed on upper spider in positions such as the diagonal of die, is radiated on veneer, is convenient to stamping-out and quick and precisely locates during stamping-out.Cylinder execution speed is fast, and compared with therefore mending machinery by replacing a damaged part with other a few class existing, operating efficiency is higher.

Air compressor wide spectrum is easily purchased, low price, and natively there is air compressor general plywood factory, so the utility model selects air compressor machine can save user's equipment investment as power source.For the user that air compressor machine is distant, frame arranges small gas storage tank, the speed of stamping-out can be significantly improved.

The beneficial effects of the utility model are: one be solve central layer edge larger " V " shape gap and middle larger oval hole cannot the problem of Machine Repairing, two is solve panel tiny defect to lack the problem that efficient mechanical repairs.Pneumatic stamping-out speed is fast, and operating efficiency is high, and machine construction is simple, and cost is not high, is easy to promote, can alleviates veneer and mend labour intensity by replacing a damaged part, raise labour efficiency, improve timber utilization rate.
