Abstract
A discontinuous coating device comprises a measurement pump, a valve, an extruding mouth, a controller, a back roller and a material-storing jar, wherein the material-storing jar, the measurement pump, the valve and the extruding mouth are sequentially communicated in series, a discharge opening of the extruding mouth is aligned to a coating roller face, and the controller is respectively connected with the valve and a coating roller in an electrical mode. Coating fluid is accurately quantitated through the measurement pump, is conveyed to a feeding pipeline system, enters a cavity body of the extruding mouth through a three-way switching valve, flows out of a lip portion of the extruding mouth through a flat channel of the extruding mouth, and is coated on a support body, and therefore coating is formed on the support body. When the controller switches the fluid to be changed and discharged in the material-storing jar through the valve, the back roller moves away from the extruding mouth, a coating process is stopped, blank space is reserved on the support body, and discontinuous coating is achieved. The discontinuous coating device can carry out discontinuous coating on the support body, the thickness of the coating can be predetermined, and the coating process is simple, few in error, uniform in thickness, and high in precision.
Description
Technical field
The utility model relates to the apparatus for coating technical field, relates in particular to a kind of interruption apparatus for coating.
Background technology
At present, the apparatus for coating that can be interrupted is to combine (such as Fig. 1) by comma scraper 1, applicator roll 2, back flow roll 3 and hopper 4.Coating fluid sticks to rotary coating roller 2 surfaces, takes the gap location of comma scraper 1 and applicator roll 2 to from hopper 4, scrapes off unnecessary feed liquid by comma scraper 1, so, at the liquid coating of applicator roll surface formation even thickness.When the back flow roll 3 of applicator roll 2 and backwards rotation contacts, coating is transferred on the support 5 that surrounds on the back flow roll 3, form coating section 6; When applicator roll 2 separated with back flow roll 3, the coating transfer process was interrupted, and formed clear band 7 at support, left and closing motion by control applicator roll 2 and back flow roll 3, realized being interrupted coating.
Above-mentioned interruption apparatus for coating, by two of scraper roller coat and reverse roll transfer coated coating process independently, larger on coating weight (with the weight of coating liquid on the unit are) impact, the coating uniformity can not accurate be controlled, and coating target coating weight thickness can not pre-determine before coating, can only after the coating test, just can reach the target coating weight through repeatedly adjusting, so that cost is higher.
The utility model content
The purpose of this utility model is to design a kind of novel interruption apparatus for coating that can evenly be coated with, and addresses the above problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of interruption apparatus for coating, comprise applicator roll, storage tank, comprise measuring pump, valve, extrusion nozzle and controller, the connection of connecting successively of described storage tank, described measuring pump, described valve and described extrusion nozzle, the discharging opening of described extrusion nozzle is aimed at the applicator roll roll surface, and described controller is electrically connected with described valve and described applicator roll respectively.
Described valve is three-way switch valve, and described three-way switch valve one end is communicated with described measuring pump, and an end is communicated with described extrusion nozzle, and the other end is communicated with described storage tank, and described measuring pump, described three-way switch valve and described reserves tank form the closed-loop path.
Described controller is controlled the switching direction of described three-way switch valve.
Described applicator roll can move left and right, and described controller is controlled described applicator roll action.
Described extrusion nozzle comprises cavity, flat channel and extruding lip, and described cavity is communicated with by described flat channel and described extruding lip, and described extruding lip is described extrusion nozzle discharging opening.
Described extruding lip is vertical with the tangent line of described applicator roll roll surface.
The beneficial effects of the utility model can be summarized as follows:
1. interruption apparatus for coating coating process of the present utility model is simple;
2. interruption apparatus for coating of the present utility model makes coating more even;
3. interruption apparatus for coating of the present utility model can accurately be determined coating weight in advance.
Description of drawings
Fig. 1 is that prior art is interrupted the coating technique work sheet.
Fig. 2 is that the utility model is interrupted apparatus for coating coating state.
Fig. 3 is that the utility model interruption apparatus for coating is not coated with state.
The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The coating process of interruption apparatus for coating of the present utility model as shown in Figure 2, comprise storage tank 6, measuring pump 1, valve 2, extrusion nozzle 3, back flow roll 4 and controller 5,4 of extrusion nozzle 3 and back flow rolls leave a gap, when extrusion nozzle 3 and back flow roll 4 near the time, fix as required the width in described gap, support passes through between described gap.Support surrounds on the back flow roll 4, and back flow roll 4 drives support when rotating and travels forward, by the gap between extrusion nozzle 3 and the back flow roll 4.When needing to form the coating section, the coating fluid is transported to the feed pipe-line system by measuring pump 1, controller 5 by-pass valve controls 2 and extrusion nozzle 3 conductings, the coating fluid imports the cavity 7 of extrusion nozzle 3 through valve 2, flow out extruding lip 9 in the flat channel 8 by extrusion nozzle 3, be coated on the support, form coating at support.
The not coating process of interruption apparatus for coating of the present utility model as shown in Figure 3, when controller 5 by-pass valve controls 2 are got back to storage tank 6 during with the direct fluid reflux line, fluid no longer imports extrusion nozzle 3, fluid in the flat channel 8 of extrusion nozzle 3 stops to flow to extruding lip 9, liquid film fracture between extrusion nozzle 3 and the support, while back flow roll 4 outwards mobile and extrusion nozzle 3 separates, and coating process interrupts, support formation one clear band of advancing.
Above-mentioned Fig. 2 and Fig. 3 interprocedual form discontinuous interruption coating every repeating at support, realize being interrupted coating.
Interruption apparatus for coating of the present utility model is controlled coating section and clear band length by the time of the folding relative motion of control extrusion nozzle 3 and back flow roll 4, and the realization fixed length is interrupted coating.Simultaneously, input the flow of the fluid of extrusion nozzle by the control measuring pump, accurately control coating weight, coating weight makes it.
More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement etc., all should be included within the protection domain of the present utility model.
