Description

Metal base coating machine

Technical field

This utility model is related to technology for coating field, and more particularly, to one kind is for coating slurry on metal base Metal base coating machine.

Background technology

In prior art, printing technology except product description, packing box, etc. on paper printing matter prevailing in addition to, in gold Belong to and being also widely used on base material.In a lot of concrete applications, because silk-screen technology is generally not suitable for consecutive production, because This, it usually needs it is covered with function of glue coating on metal base using coating machine, typically using applicator roll, glue is transferred to gold Belong on base material, however, generally more than 10 μm of the coating thickness of Printing techniques of the prior art and extrusion forming technology, Then it is difficult to ensure that the homogeneity of coating thickness less than 10 μm, bubble easily occurs, lacks material or lead to metal forming to be crumpled etc. and ask Topic.And with industrial expansion, the overlay film coating of metal base also requires that more and more thinner, or even coating layer thickness is required to be only 1 μm, And existing metal base coating machine is unable to reach this technical requirements.

Utility model content

The purpose of this utility model is to overcome the shortcomings of what above-mentioned prior art existed, provides a kind of microthin coating, thickness Degree high precision, uniform, the imperforate metal base coating machine of film.

This utility model solves its technical problem and be employed technical scheme comprise that：A kind of metal base coating machine, including machine Head roller, applicator roll, bottom roller, blade groove is set near applicator roll, the top layer of described applicator roll is plastic layer, the outer surface of plastic layer The array of upper evenly distributed grid, is respectively arranged with scraper in the upper and lower of applicator roll, and described scraper arranges plastic cement cutting edge, institute State the flow regulator that blade groove is arranged with coating.

Described applicator roll is by Motor drive.

Described scraper arranges angle regulator.

Two stage speed change gear drive group is set between described motor and applicator roll.

The trellis depth of described applicator roll is less than 10 μm.

Compared with prior art, the beneficial effects of the utility model are：

This utility model application gravure application, controls coating layer thickness with grid, and multiple independent grids ensure that coating Uniformity, effectively prevent coating process occur bubble, lack material phenomenon, be particularly well-suited to be formed on metal base thickness Ultra-thin coating, and its structure is simple, easily operated.

Brief description

Fig. 1 is the side structure schematic view of this utility model metal base coating machine.

Fig. 2 is the applicator roll structural representation of this utility model metal base coating machine.

Specific embodiment

Embodiment of the present utility model is described below in detail, the example of described embodiment is shown in the drawings, wherein ad initio To the element that same or similar label represents same or similar element or has same or like function eventually.Below by ginseng The embodiment examining Description of Drawings is exemplary, is only used for explaining this utility model, and it is not intended that to of the present utility model Limit.

Of the present utility model description in it is to be understood that term " in front and back ", " on ", D score, "left", "right", " hang down Directly ", the orientation of instruction such as " level ", " interior ", " outward " or position relationship are based on orientation shown in the drawings or position relationship, are only For the ease of description this utility model with simplify description, rather than instruction or the hint device of indication or element must have specific Orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.

In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace Dress ", " being connected ", " connection " should broadly understood, for example, it may be being fixedly connected.Can also be to be detachably connected, or integratedly Connect；Can be to be mechanically connected or electrically connect；Can be to be joined directly together it is also possible to be indirectly connected to by intermediary, It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition Language is in concrete meaning of the present utility model.

Referring to Fig. 1-2, a kind of this utility model metal base coating machine, including head roller 1, applicator roll 2, bottom roller 3, close Applicator roll arranges blade groove 4, and the top layer of applicator roll is plastic layer thus becoming coating rubber roll, and the outer surface of plastic layer is uniformly arranged The array of row grid（Not shown）, it is respectively arranged with scraper in the upper and lower of applicator roll（Not shown）, scraper setting plastic cement sword Mouthful, or, all using plastic cement product, blade groove is arranged with the flow regulator 5 of coating to whole scraper.

Applicator roll is driven by motor 8, arranges two stage speed change gear drive group 7 between motor and applicator roll.Scraper arranges angle Degree adjusting means 9, the trellis depth of applicator roll is less than 10 μm.

The head length-width ratio of metal base coating machine is 1500：460, power side by speed reducing ratio be 1：5 motor provides Power, from motor after one-level speed change, then by helical gear 44：34 teeth reach as two stage speed change, the power after speed change Coating rubber roll, makes coating rubber roll speed can reach 169m/min, rotating speed can reach 375r/min, with this simultaneously by the pump housing glue Through pipeline suction blade groove inner chamber from plastic container, there are two groups of flow regulators below blade groove, rotation flow is adjusted Handle 6 controlling the size of glue flow and the size of flow velocity, accordingly even when pump housing pressure is excessive also can preferably control Glue quantity, enables glue quantity to reach a stationary value, so that glue can uniformly be distributed on coating rubber roll, makes to be applied Coating can uniformly be stablized.

When controlling coating film thickness it is ensured that the flow that limited of volume control device is constant, the regulation spiral shell at governor motion two ends Bar, the end cap being rotated further by handpiece operation side after being adjusted to certain position enables scraper body to reach the adjustment of different angles, So that institute's coating layer can reach the demand of different clients.About coating layer thickness uneven when, can according to institute's coating layer not Depth information with position makees the fine setting in left and right direction to scraper, can carry out the adjustment of different azimuth during adjustment simultaneously, when reaching During the ideal value of required adjustment, directly fixed with soket head cap screw after stable and be allowed to can be mass.

When glue overflows inner chamber, drive glue to rotate through upper blade with roller by coating rubber roll, make glue on coating rubber roll Coating can uniformly be distributed in each grid of roller, scrapes off unnecessary glue through lower coating blade piece again after rotation, makes upper blade piece More uniform during upper coating.The glue now overflowing and scraping off flows to glue feed basin, then enters in plastic container by glue feed basin, Enable to recycle, reduces cost.

While there has been shown and described that embodiment of the present utility model, it will be understood by those within the art that： Multiple changes, modification, replacement can be carried out to these embodiments in the case of without departing from principle of the present utility model and objective And modification, scope of the present utility model is limited by claim and its equivalent, in changing of being made without creative work Enter, should be included within protection domain of the present utility model.
