Description
Technical field
The invention belongs to slab processing equipment technical field, more particularly to a kind of quick vertical veneer of toe joint continuously splices machine
And its splicing process.
Background technology
With expanding economy, requirement of the people to house and furniture finishing material is higher and higher, and the demand of timber is got over
Come it is bigger, in traditional timber processing industry, usually all be using pure plank as building and ornament materials, due to whole trees quilt
It is processed into that the part of timber is limited, so that the utilization rate that result in trees is relatively low.
The appearance of wood plywood solves the problems, such as that trees are processed into that pure plank utilization rate is low, its structure is veneer layer through upper
Glue, drying, compacting form, it is disadvantageous in that process is numerous and diverse, cost is higher, is unsuitable for large-scale production.So occur
Finger-jointed plate jigsaw, finger-jointed plate jigsaw be by log successively through blocking, deburring, drying, broach, docking form finger-jointed plate, Ran Houzai
Finger-jointed plate jigsaw will be spliced into after finger-jointed plate gluing, the appearance of finger-jointed plate jigsaw is so that the utilization rate of trees has obtained greatly carrying
Height, and production process is simple.
By retrieval, Application No. 201410204046.5 discloses a kind of solid wood sheet and its board-splicing process, wherein
A kind of solid wood sheet includes upper and lower two layers of ply, and layer of non-woven fabric, upper and lower two layers of timber are laid between two layers of ply

Step is as follows：
1) stock up, veneer slab working width:1000-1550mm, processes thickness：1.0-4.0mm；
2) trimming, is delivered to broach mechanism by conveyer belt and positions, and both-end broach mechanism acts at the same time after positioning, before veneer
Rear end carries out broach trimming at the same time, ensures that the notch of slab is smooth and uniform；
3) dock, the slab that broach mechanism completes is sent to docking mechanism by conveyer belt, in the adjustment gap block in docking mechanism
Portion W types catch is to completing the head of broach trimming slab and carrying out gap correction, nothing with the afterbody of another broach trimming slab
Woven fabric carries out gluing by glue spreader, transmission round brush, and motor drives synchronous pulley to roll, and synchronous pulley drives synchronous belt to lead
Non-woven fabrics docks slab after introduction drive fixture draws gluing, and pressure roller presses the non-woven fabrics after gluing, right
Non-woven fabrics is cut off by cutter along clamp edges after the completion of connecing, and then repeatedly docking acts；
4) hot-forming, hot pressing cylinder rotates, and drives the hot wafering in clamping band, and continuous hot-press is carried out to the seam crossing of veneer,
Hot pressing is completed, and veneer is continued to send out by front and rear hot pressing cylinder, and it is Workpiece length-bevel grinding face width × 2 to send out distance, to ensure
Follow-up veneer is accurately positioned, process velocity 13m-25m/min；
5) either encoder determines that final cutoff length carries out veneer with scissors or saw blade cutting mode and cuts to Photoelectric Detection,
Form the vertical veneer of full-length.
6. a kind of quick vertical veneer of toe joint according to claim 5 continuously splices the splicing process of machine, it is characterised in that
For in splicing process step 3):Glue used is white glue with vinyl, phenol glue, urea-formaldehyde glue, the one or more of melamine glue.
7. a kind of quick vertical veneer of toe joint according to claim 5 continuously splices the splicing process of machine, it is characterised in that
For in splicing process step 4)：Hot-forming mode of heating is electromagnetic heating, high-frequency heating, ultrasonic Wave heating, conduction oil
One or more in circulating-heating.
8. a kind of quick vertical veneer of toe joint according to claim 7 continuously splices the splicing process of machine, it is characterised in that
Hot-forming middle 100-120 DEG C of hot wafering temperature range.
9. a kind of quick vertical veneer of toe joint according to claim 8 continuously splices the splicing process of machine, it is characterised in that
The temperature of hot wafering is 110 DEG C.
10. a kind of quick vertical veneer of toe joint according to claim 5 continuously splices the splicing process of machine, its feature exists
In for the docking mode in splicing process step 3) using nailing docking：Completed as splice point, docking at each tooth angle position
Afterwards, docking site is subjected to quick nailing with automatic plastic Martin's rifle group, veneer is firmly spliced.
