Step is as follows:
1) get the raw materials ready, veneer slab working width: 1000-1550mm, processes thickness: 1.0-4.0mm；
2) trimming, is delivered to comb mechanism by conveyer belt and positions, both-end comb mechanism action simultaneously behind location, will be single
Plate front and back end carries out comb trimming simultaneously, it is ensured that the otch smooth uniform of slab；
3) docking, the slab that comb mechanism completes delivers to docking mechanism by conveyer belt, the adjustment gap block in docking mechanism
Top W type catch to completing the head of comb trimming slab and carrying out gap correction with the afterbody of another comb trimming slab,
Non-woven fabrics carries out gluing by glue spreader, transmission round brush, and driven by motor synchronous pulley rolls, and synchronous pulley drives Timing Belt to make
Obtaining non-woven fabrics after traction seat drives fixture to draw gluing to dock slab, pressure roller carries out pressing to the non-woven fabrics after gluing,
Dock rear non-woven fabrics to be cut off along clamp edges by cutting knife, then repeat docking action；
4) hot-forming, hot pressing cylinder rotates, and drives the hot wafering in clamping band, the seam crossing of veneer is carried out Continuous Heat
Pressure, hot pressing completes, and front and back veneer is continued to send by hot pressing cylinder, sends distance for Workpiece length-bevel grinding face width degree × 2, with
Ensure that follow-up veneer is accurately positioned, process velocity 13m-25m/min；
5) Photoelectric Detection or encoder determine final cutoff length, carry out veneer with scissors or saw blade cutting mode and cut,
Form the vertical veneer of full-length.
A kind of vertical veneer of quick toe joint the most according to claim 5 splices the splicing process of machine continuously, it is characterised in that
For splicing process step 3) in: glue used be white glue with vinyl, phenol glue, urea-formaldehyde glue, melamine glue one or more.
A kind of vertical veneer of quick toe joint the most according to claim 5 splices the splicing process of machine continuously, it is characterised in that
For splicing process step 4) in: hot-forming mode of heating is Electromagnetic Heating, high-frequency heating, ultrasonic wave heating, heat conduction
One or more in oil circulating-heating.
A kind of vertical veneer of quick toe joint the most according to claim 7 splices the splicing process of machine continuously, it is characterised in that
Hot-forming middle hot wafering temperature range 100-120 DEG C.
A kind of vertical veneer of quick toe joint the most according to claim 8 splices the splicing process of machine continuously, it is characterised in that
The temperature of hot wafering is 110 DEG C.
A kind of vertical veneer of quick toe joint the most according to claim 5 splices the splicing process of machine continuously, and its feature exists
In, for splicing process step 3) in docking mode use nailing docking: each tooth angle position, as splice point, has been docked
Cheng Hou, carries out quick nailing by automatic plastic Martin's rifle group by docking site, is firmly spliced by veneer.
