Description

The disposal route of coating of tape measurer surface

The present invention relates to a kind of disposal route of coating of tape measurer surface; particularly a kind of one deck aluminium foil film or plating glued membrane of pasting on tape measure chi embryo reached a kind of disposal route that has smooth surface and can protect the printing scale not to be worn the coating of tape measurer surface that disappears again after the mylar coating.

Produce and commercially available tape measure on the existing industry, color on its chi face and scale all are to stamp scale behind baking vanish again, cover one deck polish oil or light at last more from the teeth outwards and roll and form.This tape measure along with tape measure is drawn the increase of taking out number of times, can make the scale on the tape measurer surface fuzzy gradually in use for some time, even can't dimensioning, this is the shortcoming on this tape measure uses, if from production run, then needs improved place just more.For example:

1, general tape measurer surface all is that mode with baking vanish makes the chi face form level and smooth state attractive in appearance.General baking vanish technology is directly the chi embryo to be pulled out after immersing chi embryo (normally sheet steel) in the paint bath, this moment is because chi embryo section is a cambered surface, so when paint vehicle is dry gradually, can hoard at place, chi embryo two edges the error the when paint vehicle of this position can cause the scale printing on the length and inaccurate when causing measuring.In addition, the long-pending paint vehicle of thicker trip also can allow the chi embryo roll the back and produce the phenomenon that expands, and this will cause the smooth degree of tape measure stretching motion in the chi box indirectly.

2, the chi embryo is before soaking the cloth paint vehicle, and for meeting the baking vanish requirement, the chi embryo surface must be handled very smoothly, clean, baking vanish is adhered to easily and the frivolous light of lacquer painting, and these processes are time-consuming more uneconomical again.

3, the scale mark on the traditional tape measurer surface is to republish to make behind chi embryo baking vanish, because the slickness of chi embryo baking vanish face dies down printing adhesion, under the friction of pulling-down chi face repeatedly scale is come off or smudgy, this has directly influenced dimensional measurement and accuracy.

The disposal route that the purpose of this invention is to provide a kind of coating of tape measurer surface, this disposal route is easy, and the scale that makes tape measurer surface is durable in use.

For achieving the above object, the present invention is by the following technical solutions: disposal route comprises: the pros and cons of chi embryo is done to clean again with hot blast drying with solvent after the blasting treatment, coating binder on the chi embryo face therein then, and with the flash baking coated face to kissing the subsides state; Coating one deck aluminum foil film is fitted itself and chi embryo on coated face and through roll extrusion wheels then, sends in the baking box after the chi embryo of coating aluminium film is wound into the axle volume and dries; The chi embryo of oven dry stamps scale mark on coating face, coating binder on chi embryo two sides, and flash baking again is coated on transparent membrane on the pros and cons then, through roll extrusion wheels its and chi embryo are pressed into one, at last the chi embryo are wound into and go into baking oven behind the axle volume and toast and form.

The invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is an operational flowchart of the present invention.

Fig. 2 is a device arrangement plan of the present invention.

Fig. 1 shows: the surface of chi embryo (being generally steel) is given sandblast earlier or pearl hits processing, then its surface is cleaned, dried up; Then, coating adhesive on the chi embryo face therein, and its surface dried slightly, coating aluminium foil film on the glue face again, the baking box oven dry is sent in deburring, rolling; Chi embryo after the oven dry carries out the printing scale of coating face again, and the chi embryo of finishing printing is through the double spread bonding agent, and then the coating transparent adhesive film is sent into after deburring, rolling and dried the coating processing of promptly finishing tape measurer surface in the baking box in chi embryo tow sides.

See Fig. 1, Fig. 2, the present invention at first will put in order the steel chi embryo 1 of volume and send into sand-blasting machine 2, chi embryo 1 pros and cons be done sandblast or pearl hits processing, make the chi embryo surface be processed into the rough surface with fine shrinkage pool, make the tackifier of coating be easy to adhere to; Sandblast chi embryo 1 is later sent in the ablution groove 3 immediately, will be cleaned removal by the dust of the chi embryo surface of sandblast with volatile solvent in the ablution groove 3; Chi embryo 1 after cleaning is through hot blast drying, and one side wherein is through coating machine 4 coated with adhesive, this coated face again through one rapidly dryer 5 its lip-deep tackifier is dried to tacky state; Chi embryo 1 after the above-mentioned gluing is during through one group of rolling wheel 6 and another is bonding by the aluminium foil axle volume 7 aluminium foil films 70 of drawing, and the chi embryo 1 that is stained with aluminium foil film 70 is furled axle volume 17 to send into baking box 8 bakings immediately; The axle volume 17 of drying is promptly drawn to tap into into printing machine 9 subsequently carries out the printing of scale mark, the pros and cons of the chi face that is completed for printing is through the coated with adhesive respectively of two coating machines 4 up and down ' when locating, and connects down through dryer 5 rapidly ' coated face is baked to the optimum adhesion state; Rolling up the transparent membrane 100 of pulling out at 10 places by the transparent membrane axle of upper and lower side is then affixing to it on top and bottom of chi face through 6 ' time of another group rolling wheel, the chi face of transparent membrane 100 collects axle volume 18 to send into oven dry in the baking box 8 again in the coating, the chi face that oven dry is finished is final chi face, and can carry out work such as relevant cutting of next stage, punching, riveting chi head and assembling.

In the processing procedure of above-mentioned chi face, coating aluminium foil film becomes before the transparent membrane must be muciform colloid flash baking to kissing the state of subsides on coated face through dryer rapidly 5 behind the coating binder on the chi face, and bake out temperature at this moment is comparatively suitable with 60 ℃; In addition, the aluminium foil film becomes behind the transparent membrane to send in the baking box 8 with 60 ℃～80 ℃ temperature with the chi embryo of reel harvesting and gives drying in the coating.The purpose of this program is to make stickup aluminium foil film become the tackifier energy full solidification drying of transparent membrane on the chi embryo, because the hardening agent of adding about 10% in the tackifier, this hardening agent can quicken the speed of its curing through heated baking, makes viscose glue fully the aluminium foil film be become transparent membrane and chi embryo to fit; Relevant temperature control comprises that also the chi embryo dries up the chi surface temperature after cleaning in the technology, generally is by a hot blast tunnel 12, up and down the cleansing solution on the chi face is dried up with 20 ℃～30 ℃ hot blasts.

In addition, in the relevant handling procedure of chi face, the thickness of this aluminium foil film is about 0.006mm～0.008mm, electroplates glued membrane then its thickness is between 0.012mm～0.015mm if use instead, and the thickness of coating transparent membrane is also between 0.006mm～0.012mm; Its film tow sides of aluminium foil film as printing surface are respectively that one side is a cloudy surface for bright one side.For printing is adhered to easily, the scale after the printing is distinguished easily and aesthetic property is considered, thus bonding with its bright when coating aluminium foil film with the chi embryo, with the face of cloudy surface as the printing scale; Except temperature in baking box is controlled between 60 ℃～80 ℃, all the other are controlled at about 60 ℃ in the process of coating roll extrusion, wherein each group rolling wheel also all remains on 60 ℃ of temperature, carry out speed control in the whole procedure at 30M/min～60M/min, can carry out deburring work simultaneously when in addition, each rolling chi embryo or axle are rolled up.

Advantage of the present invention:

1, through the chi face of aluminium foil film coating, its surface smoothing, the color homogeneous surpasses the smooth of general baking vanish face Degree, and color is than baking vanish face homogeneous more;

2, on the chi face coating transparent mylar, the scale of having protected simultaneously the chi face and being printed thereon Line is not damaged by any nip. On the other hand, the polyester of thickness between 0.006mm～0.012mm The chi face definition that film also allows the chi face still possess transparent brilliance after long-term shrinking used, prior That graduation mark is still possessed best interpretation resolution.

3, the chi face that produces of the present invention is because viscose glue coating homogeneous, and the thickness of aluminium foil book film and mylar is also controlled homogeneous, therefore, the chi surface evenness is good, do not have the chi face of generally making and to hoard the situation of baking vanish in chi embryo two sidelines with baking vanish, certainly do not have the problem that scale mark is exaggerated or dwindles yet, and do not have the phenomenon that expands or block the chi cover plate after batching and occur.

In a word, the present invention be a kind ofly can produce accurate tolerance, finished surface is good and scale mark is not disappeared by friction, can prolong the disposal route of the tape measure of ruler tenure of use again.
