Description
Technical field
The utility model relates to a kind of double hot melt adhesive film melt-spraying spinning plates.
Background technique
Hot melt adhesive film melt-spraying spinning plate is production low melting polyurethane hot-melt adhesive film crux component.
Hot-melt adhesive film production technology is as follows:
Low melting polyurethane particle --- squeezes out --- band hot melt adhesive film melt-spraying spinning template die head after screw extruder heating
--- disordered wet forming --- conveys heat-shaping by transmission net and reinforces --- spray crystallization solidification --- spinneret after heating and thermal insulation
Forming volume is rich.Hot-melt adhesive film production technology is mature at present, and product market competition is fierce, and improving yield reduces cost as master
Want the objective of the struggle.Hot melt adhesive from extruder pressurization squeezes into die head to former melt-spraying spinning plate basic structure under molten state as shown in Figure 1:
It assigns in the melt-spraying spinning plate of 200mm long, by a downward spinneret of row's micropore 0.3-0.5mm, then passes through micropore both sides
Compressed air is blown drawing and is refine in networking and shapes.Since spinneret amount is limited to micropore size and spray spinning plate length, specific yield
It is difficult to be promoted, causes production efficiency not catch up with the market demand, therefore there is improved spaces.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of double hot melt adhesive film melt-spraying spinning plate, Ji Nengda
To the technique requirement of spinneret, and spinneret amount can be improved, to promote yield.
To achieve the above object, the utility model provides following technical solution:
A kind of double hot melt adhesive film melt-spraying spinning plate, including plate body, electric heating tube and compressed air hose；The plate body it is upper
Surface has holding tank, offers two rows of spinneret orifices on the bottom surface of the holding tank；Mounting hole is offered in the plate body, it is described
Mounting hole is located between two rows of spinneret orifices, and electric heating tube is set in mounting hole；There are two the compressed air hose tools, and
Set on the lower surface of plate body, and it is located at the two sides of two rows of spinneret orifices, all has fumarole on each compressed air hose.
Preferably, it is the wind guide strip of triangle that the lower surface of the plate body, which has two sections, two rows of spinneret orifices respectively with
Two wind guide strips are corresponding up and down, and the lower end of spinneret orifice passes through wind guide strip.
Preferably, the joining place of the lower surface of the side wall and plate body of the wind guide strip has mounting groove, the compressed air
Pipe is set in mounting groove.
The advantages of the utility model are as follows: double spinneret orifice can effectively improve spinneret amount, with improving production efficiency；Simultaneously
Electric heating tube is set between two rows of spinneret orifices, can effectively promote spinneret quality, to meet the technique requirement of spinneret.
Detailed description of the invention
Fig. 1 is the schematic diagram of double hot melt adhesive film melt-spraying spinning plate provided by the present embodiment.
Specific embodiment
The double hot melt adhesive film melt-spraying spinning plate of the utility model is further described by Fig. 1.
A kind of double hot melt adhesive film melt-spraying spinning plate, including plate body 2, electric heating tube 3 and compressed air hose 4；The plate body 2
Upper surface there is holding tank 21, offer two rows of spinneret orifices 22 on the bottom surface of the holding tank 21；It is offered in the plate body 2
Mounting hole 23, the mounting hole 23 is located between two rows of spinneret orifices 22, and electric heating tube 3 is set in mounting hole 23, by plate
Body 2 heats, the spinneret quality of the two rows of spinneret orifices of raising, and in the present embodiment, the heating temperature of heating rod is 160 degree to 190 degree；Institute
It states there are two the tools of compressed air hose 4, and is connected with air compressor, and be set to the lower surface of plate body 2, and be located at two rows of sprays
The two sides of wire hole offer fumarole on air compressed pipe, the silk sprayed from spinneret orifice are blown drawing and refine into web forming.
Further, it is the wind guide strip 25 of triangle, two rows of spinneret orifices that the lower surface of the plate body 2, which has two sections,
It is corresponding up and down with two wind guide strips respectively, and the lower end of spinneret orifice passes through wind guide strip.Under the setting, spinneret orifice both can increase
Effective length improves the spinneret quality of spinneret orifice, and can play the role of guiding to the gas blown out out of compressed air hose 4, keeps away
Exempt to interfere with each other problem between air-flow when two compressed air hoses 4 work.
Further, the joining place of the lower surface of the side wall of the wind guide strip and plate body 2 has mounting groove 24, the compression
Air hose 4 is set in mounting groove 24, which being capable of the installation of constant compression air hose on the body.
When the utility model is used, being installed on the heating and thermal insulation die head 1 of hot melt adhesive.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
