Abstract

The utility model provides a new paint roller coating device, which can feed the paint to the working surface of a roller continuously and uniformly, adopting an air-intake small hole and the electromagnetic piston pump of the exhaust valve of a small rubber tube to provide pressure source for a sealed container. The output quantity of the paint of an elastic paint output device is controlled via an adjusting valve under the air pressure, and the paint can be diverted to the working surface of the roller continuously and uniformly; the paint can be coated on objects by that the roller is pushed. The new paint roller coating device of the utility model which adopts the operational mode of the outer feeding of the roller has low operating pressure and high work efficiency, preventing the paint spitting to pollute the environment, and the feeding quantity is easy to master.

Description

Power-driven rolling dauber

The utility model relates to a kind of improved electronic coating roller coating apparatus, is specially adapted to toward the device than coated coating on the large tracts of land object.

Present domestic cylinder is coated with apparatus for coating and uses extensively at aspects such as building, shipbuildings, and its major defect is that cylinder needs repeated multiple times to stop coated work, and removes be stained with coating.Therefore one, efficient is low, two, coating is inhomogeneous will repeatedly roll repeatedly.In recent years external existing electronic roll-on device emerges, and reduces labor intensity greatly, has improved operating efficiency.As Xi Erka (searc), the Warner lattice (POWER ROLLER) of the U.S., but these products all adopt feed working method in the cylinder.Major defect one, the big operating pressure (15-32 pound/inch of needs ²), want high to the seal request of device is corresponding.Two, because coating must often be full of cylinder inside, the feed situation is difficult to grasp, and splash pollutes to neighbouring surface easily.Three, coating quality is required height, the coating that viscosity is big need dilute the back to be used.The pressure source of these products all adopts aluminium casting electromagnetism diaphragm pump in addition, and material and technological requirement to diaphragm and plate valve in fast turn-around also are very high, could guarantee its working life like this.

The purpose of this utility model is that a kind of improved electronic paint roller coating device will be provided, and it can solve above-mentioned defective preferably, accomplishes at low operating pressure (1-1.5kg/cm ²) under coating is fed on the working face of cylinder continuously equably, cylinder is not had seal request, coating quality is required low, the operator can hold coating quality rapidly, prevents that the coating splash from polluting and wasting.Adopt improved electromagnetic piston pump in addition, simplified structure has improved reliability, has reduced manufacturing cost.

Task of the present utility model is finished as follows: from the next coating of defeated material flexible pipe, enter elastic coating follower on the rolling stand through control valve, because the line gap mouth of the pressure spreading elastic coating follower of coating, be stranded on the splashproof lip, coating is stained with equably and is bonded on the cylinder working face when promoting cylinder, and coated is on the coated article body thereupon.The operator just can continuous operation hold coating quality as long as regulate the coating inlet amount like this.Owing to adopt the outer feed working method of cylinder, need not to increase the pressure that coating is extruded into skin-surface in the cylinder, therefore cylinder there is not seal request, quality and viscosity to coating are less demanding, so operating pressure can reduce greatly, reduced the seal request of this device is also corresponding, as long as the discharge pressure of coating satisfies coating delivery head and the required pressure of spreading elastic coating follower.

The electromagnetic piston pump that pressure source of the present utility model adopts is to constitute like this: radially along accounting for some air inlet apertures on the position of piston bottom dead centre, replace the air inlet plate valve at cylinder wall.Air bleeding valve adopts small rubber hose to be enclosed within on the cylinder valve body that occupies exhaust hole, finish the air inlet program at the piston lower dead point position, finish the program of calming the anger at upper dead center position, utilize the effect of alternating electromagnet and return spring, promote the reciprocating motion of the pistons that polytetrafluoroethylene (PTFE) is made, simple and reliable for structure, the teflon piston long working life, the small rubber hose transposing makes things convenient for expense extremely low.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the structure chart of this device.

Fig. 2 is the longitudinal sectional view of this device pressure source electromagnetic piston pump.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

When this device pressure source electromagnetic piston pump 1 to airtight container 2 input compressed air, after this container was set up operating pressure, coating was promptly along the elastic coating follower 7 of defeated material flexible pipe 3 fast changeable on control valve 4 input rolling stands 5.Because the tubulose elastic coating follower main body 7-1 spreading that the pressure of coating is made elastomeric material, coating flows out line gap mouth 7-2 place and enters in the U-shaped groove of splashproof lip 7-3, promote cylinder 6 this moment, fine hair on the cylinder 6 promptly is stained with coating, transfers with regard to coated on the coated article body.

Coating can not leak from line gap mouth 7-2 when the elastic force of elastic coating follower main body 7-1 should guarantee that control valve 4 cuts out.Coating maximum demand when elastic coating follower 7 maximum output flows should equal cylinder 6 work.

The working face of elastic coating follower 7 is the stream that spatters that the effect one of splashproof lip 7-3 can prevent coating, and two can be used as the middle storage stationary point before coating enters cylinder 6, guarantee the even of cylinder 6 working face coating.

The operator can handle control valve 4 according to the coated situation, and control enters the coating content of cylinder 6 working faces, obtains good coated quality.

The pressure source of this device is to be provided by electromagnetic piston pump 1.With reference to Fig. 2, radially account for some air inlet aperture 1-5 at cylinder 1-4 along piston 1-3 lower dead point position, when moving forward, piston 1-3 promptly seals air inlet aperture 1-5 under the promotion of alternating electromagnet 1-1, air compresses at once in the cylinder, when piston 1-3 arrived upper dead center position, compressed air promptly backed down the small rubber hose 1-7 that is wrapped on the valve body 1-6 in the aperture of exhaust valve 1-6 and enters airtight container 2.Because the effect alternating electromagnet 1-1 of alternating current discharges, piston 1-3 gets back to lower dead point position under return spring 1-2 effect, and the working in reciprocating mode of going round and beginning again like this provides compressed air to airtight container 2.
