Abstract

The utility model provides a dual-faced applying device for coiled metal-sheet material, which adopts the electric force to drive a plurality of groups rollers wheels and a roller type painting device. The coat curing oven adopts an assembling type oven. The surface coat of the coil material is drying solidified in the oven without the direct contact of the stove body. The utility model can spread identical or different color/colors or kind paint/paints on both surfaces of the coil material at the same time. The utility model has the advantages of low cost and high quality. The utility model can expeditiously change the color and the coat and is suitable for painting the metal shutters, easy open end of the two-piece cans and other products.

Description

Dual-surface Dual-colour applying device for coiled metal-sheet material

The utility model is a kind of metal sheet band coil painting device that is used for.Be particularly useful for the application of strip coiled materials such as large batch of aluminium alloy, copper alloy, iron sheet, tinplate, silicon steel sheet.

At present, generally adopt the Powder Electrostatic Coating Technology application, but adopt this technology to exist the cost height the application of aluminum alloy beancurd leaf curtain blade, the toning difficulty, to compare paint film appearance poor with similar solvent based coating.And can only be coated with a kind of color on the two sides of coiled material.Or the coating of same kind of kind.Employed painting device needs in advance strip to be passed each working region of finishing line when adopting traditional handicraft to produce, and front and back two volume coiled materials are connected from beginning to end.And with the rolling tube as power, the pulling strip move.When paint solidification, adopted the baker of making one.The painting device schematic diagram that Fig. 1 sprays paint for existing powder static electricity.1 cradle among the figure, 2 riveting sets, 3 sinks, 4 potchers, 5 electrostatic paintings and drying oven, 6 rolling tubes.

The utility model aims to provide and a kind ofly can be coated with two kinds of different colours or two kinds of different classes of coating on metal sheet band coiled material two sides respectively.Also can only be coated with one side.It is end to end not need to roll up coiled materials with two, and is equipped with assembled baker and the painting device that can reduce production costs significantly.

This device is by the storing mechanism feed mechanism device of tinting.Coating curing oven and receiving mechanism are formed.Of the present utility model being characterised in that: feed mechanism form by some groups of feeding rollers wheel and via motor transmission deceleration rear drive it.Coiled material moves under the drive of running roller.Tint device by colouring roller 18, and the even look roller 19 and the roller 20 of tinting are formed.Colouring roller 18 contacts with coating, and even look roller 19 places colouring roller 18 and tints between the roller 20.The device of tinting places up and down each one group of both sides of coiled material.The roller 20 of tinting is close to the surface of coiled material respectively.Colouring roller 18 with tint roller respectively by power drive.Can coat similar and different coating in two surfaces up and down at coiled material on demand.The coating curing oven is made up of the baking oven that one or several has same structure.Its structure as shown in Figure 3, Fig. 3 is the A-A sectional view among Fig. 2.Blow vent 32 is arranged at the bottom of baking oven housing 26 inner chambers, and each blow vent links to each other with breather line 33, the relative reflecting plate 27,31 that is equipped with radian between interior cavity wall and the blow vent.The reflecting plate inboard is equipped with two rows heating element heater 28,30 relatively.Coiled material 29 places in the space between two heating element heaters.Curing oven also can source of the gas of each baking oven configuration by the sky air source central gas supply that contracts.Under the driving of running roller, deliver to curing oven behind the coiled material coating, coiled material under the formed air curtain supporting of the air that transfers out from blow vent, move forward, and meanwhile under the baking of hot-air, the coating dry solidification.The utility model is compared with existing painting device to have and can be coated two kinds of different colors or different types of coating on the coiled material two sides respectively.It is strong, with low cost to have the coating quality high compactness.Colour changing is convenient, rapid when production operation, automaticity is high.Advantages such as the paint solidification time, comparable conventional device shortened 2～6 times, lacked so have drying tunnel, and floor space is little.

Be an embodiment of the present utility model below.

The application main technique of present embodiment is uncoiling---cleans---rinsing---phosphatization---rinsing---oven dry---roller coating---curing---rolling.For cooperating this production technology to be achieved, adopted painting device as shown in Figure 2.Each parts is among Fig. 2: 7, uncoiling frame, 8, coiled material, 9, running roller, 10, rinse bath, 11, running roller, 12, potcher, 13, running roller, 14, phosphatization groove, 15, running roller, 16, potcher, 17, running roller, 18, the dead small roller, 19, the gap bridge roller, 20, big coating roller, 21, travelling gear, 22, baking oven, 23, compressed air gas source, 24, running roller, 25, the rolling frame.After having finished operations such as cleaning, rinsing, phosphatization rinsing, oven dry by the drive of a series of running rollers after the uncoiling of metal sheet band coiled material, enter the operation of tinting.The roller component of tinting becomes two groups up and down, places coating according to the requirement of technology in coatings tank, makes the coating roller also be stained with coating by feeding roller and refining roller, and the coating roller can be adjusted by the needs of coiled material.Behind the coiled material coating, be sent to curing oven.Coiled strip is on the one hand because the effect of the motive force of running roller moves forward it, on the other hand because the supporting of curtain air and unlikely sinking.The gas outlet is equipped with at the top of baking oven, make air in baking oven after heating, form cross-ventilation.Dry solidification gradually in the process that coating moves in case.The coating on coiled material surface is solidified fully when leaving baking oven at last.By receiving mechanism it is packed up again.

Claims
