The additives such as agent, coloring agent, agent for capturing are entered in static mixer 51 from the additive pipe 56 of wing passage, additive and gluing
Agent is atomization in static mixer 51 and is thoroughly mixed to form intermixture.
Static mixer 51 is provided with, additive was introduced in static mixer 51 before into mixing tube with adhesive,
Spiral spray device is provided with static mixer 51, additive can be fully atomized simultaneously with adhesive in static mixer 51
Be uniformly mixed to form intermixture, again intermixture be delivered in mixing tube 52 afterwards and be allocated, substantially increase additive with
The uniformity of adhesive mixing, it is not necessary to add more additives, it is ensured that the performance requirement of product, increased the conjunction of product
Lattice rate and reduce production cost.
Then intermixture is transported in mixing tube 52, mixing tube 52 is connected with applying glue spray gun 54, mixing tube 52 and applying glue
A plurality of communicating pipe is provided between spray gun 54, a three-way diverter valve 57 on every communicating pipe, is equipped with, mixing tube 52 is by intermixture
Applying glue spray gun 54 is delivered to after being assigned in every communicating pipe, applying glue spray gun 54 is provided with steam hole 12, steam hole 12 and steam
Allotter is connected, and is connected by pipeline between steam distributor and steam hole 12, and pipeline is provided with steam valve, works as nozzle during applying glue
After fully opening three seconds, steam valve is opened, and high steam is passed through in applying glue spray gun 54, when intermixture is entered in applying glue spray gun 54
Afterwards before applying glue spray gun 54 is sprayed, the intermixture that nozzle sprays is broken up atomization by high steam, then again from applying glue spray gun 54
Outlet sprays.
The nozzle assembly 2 that applying glue spray gun 54 is included fixed seat 1 and is connected with the fixed seat 1, nozzle assembly 2 include nozzle
21,1 one end of fixed seat is connected with blow-off pipe 4, intermixture and the blow-off pipe 4 of the adhesive that nozzle assembly 2 is sprayed and additive
Interior material fiber is mixed, and 1 side of fixed seat is provided with steam hole 12, and steam hole 12 is connected with high steam allotter,
The intermixture that nozzle 21 sprays is entered in fixed seat 1, and steam hole 12 sprays high steam and fully breaks up intermixture, greatly enhances
The atomizing effect of intermixture, can only be realized by increasing pressure to improve atomizing effect in prior art, and increase pressure
Power need by the outlet of nozzle do it is especially little, not only the outlet of higher pressure transient but also nozzle is less can be easy to make
Into blocking, cause production unstable, affect work efficiency, the present invention there be higher pressure but will by high steam
Intermixture is broken up to realize more preferable atomizing effect, so the outlet of nozzle avoids the need for being made thin little, so substantially reduces
Blocked probability, it is ensured that production is stablized and production efficiency.
Fixed seat 1 is additionally provided with diffuser cap 11 with 4 connection end of blow-off pipe, and 11 one end of diffuser cap is fixed in fixed seat 1, separately
One end is goed deep in blow-off pipe 4, and diffuser cap 11 is provided with a connection fixed seat 1 and the opening of blow-off pipe 4, opens on the inside of the diffuser cap 11
Multiple second are provided with mouthful to cut line groove, the intermixture Jing high steams that nozzle 21 sprays break up last from opening ejection, and second cuts
Wire casing can be such that intermixture sprays in the shape of a spiral to be further atomized, make atomizing effect more preferable.
Last applying glue spray gun 54 is ejected into intermixture in blow-off pipe 4 and is mixed with material fiber, and applying glue terminates.
High steam is passed through into after applying glue spray gun 54 while nozzle spurts in intermixture, high steam is by intermixture
Atomization is broken up, is sprayed in blow-off pipe 4 again afterwards, substantially increase the atomizing effect of intermixture, can be with the material in blow-off pipe 4
Fiber is sufficiently mixed, and timber intensity improves 30%-50%, improves the utilization rate of adhesive, can save adhesive 15% left
The right side, the applying glue uniformity improve 200%, will not produce gum spot, it is ensured that the performance requirement of product, increased the qualification rate of product, and
And when defibrator rotating speed and condition change, it is capable of the ratio of stability contorting adhesive and fiber.
In Process of Applying Glue, the spray-bonding craft also includes nozzle cleaning, and 57 other end of three-way diverter valve is also associated with water under high pressure
Allotter 55, is additionally provided with two-way valve between the high pressure water dispenser 55 and three-way diverter valve 57, after applying glue terminates or by
When production line breaks down hesitation, gluing agent injection valve is closed, adjust the position of three-way diverter valve 57, connect water under high pressure
Allotter 55 and applying glue spray gun 54, open two-way valve, and water under high pressure is finally sprayed into by being injected to communicating pipe in applying glue spray gun 54
To in delivery pipe 4, discharged by delivery pipe 4, pipeline and nozzle are cleaned the industrial chemicals remained in pipeline are poured
In blow-off pipe 4, it is ensured that there is no the adhesive of Thermocurable in passage, spray will not be blocked in next applying glue due to residue
Mouth.
After cleaning 60 seconds, stop water spray, nozzle is closed, prepare next applying glue.
Automatically cleaning can improve equipment normal operation rate to nozzle, and split run increases yield 13.7%, and it is clear that nozzle cleans reduction automatically
The loss of washed journey glue and waste, reduce pollution of the waste discharge to environment.
4 one end of blow-off pipe is connected with defibrator 58, and the other end is connected with drying machine 59, and material is ground by defibrator 58
It is ejected in blow-off pipe 4 into pulp fiber and is mixed with adhesive and other additives, then is transported to that drying machine 59 is interior to be carried out
It is dried, then carries out the processing and forming of sheet material.
Above content is with reference to specific preferred implementation further description made for the present invention, it is impossible to assert
The present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of without departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
