Abstract
A flexible scrapper for coater is composed of a coating roller that may be dipped in size box, a flexible sponge scrapper at the central front of the coating roller, and a press rod to control the pressure of the flexible scrapper, and features uniform coating, high quality of coated layer and simple structure.
Description
The present invention relates to a kind of coating blade that is used on the coating machine, especially can make the uniform a kind of flexible scraper for coating of coating.
At present, the equipment that pressure sensitive adhesive backguy (being commonly called as aureate pullcord) is easily sealed off in employed production external packing is coating machine, and Fig. 1 is existing coating machine structured flowchart, is made up of to the base material wrap-up to apparatus for coating to drying device the base material pay-off again.In the production technology of pressure sensitive adhesive backguy, at first will be coated with adherent layer to substrate plastic film handles, carrying out pressure-sensitive adhesive coating again handles, this two procedures directly influences the quality quality of product, and the apparatus for coating decisive role of coating machine, existing apparatus for coating provides two kinds of topology views of critical piece by Fig. 2, Fig. 3, first kind shown in Figure 2, form by glue case 2, glue spreader 3 and metallic spatula 1, glue spreader is with the glue rotation counterclockwise, plastic film substrate 4 pastes the glue spreader walking clockwise, and metal scrapes nine will be with the glue spreader glue-line drawout of glue.Second kind shown in Figure 3, is made up of glue case 2, glue spreader 3 and metallic spatula 1 equally, and glue spreader is with the glue rotation counterclockwise, and plastic film substrate 4 pastes the glue spreader walking clockwise, and metallic spatula will be stained with the plastic film substrate glue-line drawout of glue.Above-mentioned two kinds of structures because the walking of the not high generation vibrations of mechanical precision and plastic film substrate is not steady, are required coating layer thicknesses when thin by it, usually can produce phenomenons such as crawling and holiday.
The purpose of this invention is to provide a kind of flexible scraper for coating, it is not only simple in structure, by debuging perfect square just, the more important thing is the quality that has improved the product coating.
The objective of the invention is to be realized by following technical scheme: it comprises the two side of interior cogged, bearing, the planker of two shore supports that are connected with sidewall, be placed with the glue case on the planker, it is characterized in that: glue spreader connects in two side, the glue spreader bottom impouring glue case, the glue spreader middle front part is equipped with shape with holes or non-poroid flexible scraper, flexible scraper connects with the depression bar that is connected the two side, the two side front middle part is equipped with threaded tuning knob, and tuning knob withstands the degree of tightness that depression bar is regulated flexible scraper and glue spreader.
Flexible scraper is selected sponge, rubber, nonwoven cloth material for use.
Flexible scraper is the circle that rectangle, semicircle, centre have circular hole.
The present invention compared with prior art has tangible advantage and good effect, has adopted such scheme can make the product coating evenly, does not produce holiday, has improved institute's coating thickness precision, and it is simple for structure.
, be described in detail as follows a kind of specific structural features and effect that is coated with the face flexible scraper that foundation the present invention proposes below in conjunction with accompanying drawing and preferred embodiment:
Fig. 1 is coated with face machine structured flowchart.
Fig. 2 is existing coating machine apparatus for coating critical piece view.
Fig. 3 is the another kind of apparatus for coating critical piece of an existing coating machine view.
Fig. 4 is a coating machine apparatus for coating flexible scraper critical piece topology view of the present invention.
Fig. 5 is the cutaway view of Fig. 4 of the present invention.
See also shown in the accompanying drawing 1, metallic spatula; 2, glue case; 3, glue spreader; 4, plastic film substrate; 5, flexible scraper; 6, depression bar; 7, sidewall; 8, tuning knob; 9, planker; 10, pillar.
In Fig. 4, interior cogged, bearing (prior art is not drawn) two side 7 connect the planker 9 that is supported by pillar 10, be placed with a rectangle glue case 2 on the planker 9, connect glue spreader 3 between the two side 7, glue spreader 3 bottom impouring glue casees 2, glue spreader 3 middle front parts are equipped with poroid flexible rectangle sponge flexible scraper 5, flexible scraper 5 is connected with depression bar 6, depression bar 6 two ends connect two side 7 respectively, sidewall 7 middle front parts are equipped with two threaded tuning knobs 8, tuning knob 8 withstands depression bar 6, regulates the degree of tightness between tuning knob 8 control flexible scrapers 5 and the glue spreader 3.
Fig. 5 is Fig. 4 A-A cutaway view, glue spreader 3 impouring glue casees 2, glue spreader 3 is rotated counterclockwise, and flexible scraper 5 rolls the glue that is stained with glue spreader 3 and scrapes evenly, glue spreader 3 contacts with the plastic film substrate 4 of clockwise walking, with the even coated of the glue on the glue spreader 3 on plastic film substrate 4.
