When the direction of place plane passes through the workspace, the two sides of the filtering filter paper goes out with first gum outlet, described second
The distance of Jiao Kou is identical and is 1.5mm, so as to avoid or reduce glue drop glue, wire drawing phenomenon.As preferred embodiment,
Before starting the glue-injection machine, the gel quantity by the first glue regulating valve in the first glue rifle group to first gum outlet
It is adjusted, and the gel quantity of second gum outlet is adjusted by the second glue regulating valve in the second glue rifle group
Section.With glue regulating valve, (i.e. the first glue regulating valve, the second glue are adjusted the first glue rifle group, the second glue rifle group of this example
Valve), it is knob regulating valve, by rotation of adjustment knob regulating valve, the thickness that may be injected into tree lace on filtering filter paper is adjusted
Section, improves the effective rate of utilization of glue.
As preferred embodiment, before the glue-injection machine is started, by the first design temperature and the second design temperature typing
The glue-injection machine；Wherein, the glue-injection machine is also with the first temperature control device being arranged on below the first glue rifle group and arranged on institute
The second temperature control device below the second glue rifle group is stated, first temperature control device is used for the glue in the first glue rifle group
Water is heated to first design temperature, and second temperature control device is used to heat in the glue in the second glue rifle group
To second design temperature.First design temperature and second design temperature are 150 DEG C.Glue-injection machine is mainly by temperature
Block, plastic emitting pipette tips composition are risen, temperature rise deblocking temperature set temperature is 150 DEG C, so as to fulfill the first design temperature and the second setting temperature
The adjusting of degree.
As preferred embodiment, before the glue-injection machine is started, by glue-injection machine described in pneumatic parameter typing；Wherein, institute
Stating glue-injection machine also has glue feed system and a baric systerm, and the baric systerm is used for according to the pneumatic parameter to the glue
Water supply system exports corresponding air pressure so that the glue feed system is to the first glue rifle group and the second glue rifle group
Convey the glue of equivalent.Specifically, the end connection glue entrance of plastic emitting pipette tips, glue entrance are connected with glue feed system,
Baric systerm is interconnected with glue feed system, controls glue feed system to export glue by control pressure pressure size
Water, is delivered to gum-filling mechanism.Glue injection equipment control system opens the valve of glue feed system, together by input control signal
When set baric systerm air pressure size, under the influence of air pressure, glue is conveyed according to the time of setting, last glue
Filtering its surface is expelled to, filtering filter paper injecting glue process is completed by the action of glue-injection machine.
In filtering filter-paper filter in the production process, mainly made with folded form, form trough and wave crest, passed through
Different injecting glue starting points is set, realizes two kinds of different disconnected gluing methods：
As preferred embodiment, the tree lace is injected at the wave crest of filtering filter paper, and the disconnected glue gap is positioned at filtering
The trough of filter paper.It is thusly-formed trough to break glue method, the break injecting glue scope of glue method of trough is concentrated mainly on top half, i.e. crest portion
Point, and wave trough portion then disconnects injecting glue.Tree lace length L is less than filtering filter paper and rolls over high H, at the same the tree lace on the wave crest of front with it is anti-
Tree lace on surface wave peak produces a disconnected glue gap S along filtering filter paper direction.Tree lace length L is smaller, and glue gap of breaking is bigger, it is public
Formula is：H=L+S.
The trough breaks glue method during injecting glue, mainly carries out injecting glue by glue injection equipment control system, supplies glue
System exports glue and rolls over high H less than filtering filter paper to filtering its surface, control single-unit tree lace tree lace length L.Injecting glue is inputted to rise
Initial point, making the injecting glue starting point of glue, tree lace final position ensures tree lace without departing from top half since being rolled over high top half
It is uniformly distributed on wave crest, and injecting glue is then disconnected in trough.Ensure filtering filter paper tree lace it is firm in the case of, the length of tree lace
Degree sets shorter, and breaking glue gap S will be bigger, and the effective area for filtering filter paper filtering is bigger, and air drag is with regard to smaller.
Since tree lace is located on wave crest, be with the filtering filter-paper filter without disconnected glue in appearance as, design to product, production tool
There is versatility.
As another preferred embodiment of disconnected gluing method, the tree lace is injected at the trough of filtering filter paper, the disconnected glue
Gap forms wave crest and breaks glue method positioned at the wave crest of filtering filter paper：
The break injecting glue scope of glue method of wave crest is concentrated mainly on the latter half, i.e. wave trough portion, and wave crest portions then disconnect note
Glue.Tree lace length L is less than filtering filter paper and rolls over high H, while the tree lace on the trough of front is filtered with the tree lace edge on reverse side trough
Filter paper direction produces a disconnected glue gap S.Tree lace length L is smaller, and breaking, glue gap is bigger, its formula is：H=L+S.
The wave crest breaks glue method by glue injection equipment control system progress injecting glue, glue feed system is exported glue to filtering
Its surface, control single-unit tree lace length L roll over high H less than filtering filter paper.Input injecting glue starting point, make the injecting glue starting point of glue from
Roll over high the latter half to start, tree lace terminal then disconnects injecting glue without departing from the latter half in wave crest.Ensureing to filter filter paper
Tree lace it is firm in the case of, the length of tree lace sets shorter, break glue gap S will be bigger, and filter filter paper filtering it is effective
Area is bigger, and air drag is with regard to smaller.The wave crest breaks glue method so that tree lace is hidden in trough, seems to have more from the appearance
Aesthetics, while reduce the thickness of tree lace so that the integral thickness for filtering filter paper has been reduced, and is had in volume more preferable
Advantage.
Both the above breaks gluing method in the case where ensureing filter firmness, reduces glue by the tree lace gluing method that breaks
Usage amount, disconnected glue gap L causes the effective area increase for filtering filter paper filtering, reduces the resistance of air filtration.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and replacement can also be made, these improve and replace
Also it should be regarded as protection scope of the present invention.
