The technical scheme of the utility model is: a kind of roller machine liquid storage dish device that is coated with; Comprise liquid storage dish body, Agitation Tank, circulating pump composition; It is characterized in that said liquid storage dish body is made up of fluid injection groove, work nest, overflow launder, cooling chamber; Said cooling chamber is positioned at the work nest below, and the work nest bottom is the square wave structure; The fluid injection groove is positioned at the work nest top, and dividing plate lower surface and fluid injection trench bottom between fluid injection groove and work nest leave the slit; Overflow launder is positioned at work nest one side, is provided with overfall at overflow launder and work nest junction simultaneously; Be provided with cleaning refluxing opening and collecting pipe in the work nest bottom, on the fluid injection groove, be provided with and clean liquid injection port and coating liquid injection port, be provided with condensed water inlet and floss hole, be provided with the coating refluxing opening at the overflow launder end face at cooling chamber.
During roller coat, coating circulates through Agitation Tank, valve, circulating pump, coating liquid injection port, fluid injection groove, work nest, overfall, coating refluxing opening, valve, Agitation Tank.During cleaning, cleaning fluid (pure water) is through cleaning fluid pipeline, valve, cleaning liquid injection port, fluid injection groove, work nest, cleaning refluxing opening, collecting pipe, valve, injection waste collection jar.
Compared with prior art, the beneficial effect of the utility model is:
1) liquid storage dish body is designed with cooling chamber and is positioned at work nest below, makes coating in the work nest keep the temperature of setting through circulation condensed water in cooling chamber, has avoided because of the influence of on-the-spot coating temperature to film quality;
2) work nest and cooling chamber coupling part are the square wave structural design, have increased the heat exchange contact area of the two, have promoted the heat exchange effect;
3) dividing plate lower surface between fluid injection groove and work nest and fluid injection trench bottom leave the slit; Guarantee that coating flows into work nest between the slit of fluid injection trench bottom dividing plate; Rather than the injection groove dividing plate that overflow falls into work nest from eminence, reduced the existence of coating surface bubble in the work nest;
4) be provided with the overfall of controlling coating liquid level in the work nest in work nest one side, the coating that overflows simultaneously injects the overflow launder that is close to work nest and finally flows back to Agitation Tank through overfall, has guaranteed the constant of the interior coating liquid level of work nest;
5) be provided with cleaning refluxing opening and collecting pipe at the trough place, bottom of work nest one side, automatic flushing and discharging of waste liquid to fluid injection groove and work nest when being convenient for changing coating variety reclaim, and reduce waste liquid and possibly cause environmental pollution.
