The U-wrap dual head paint coater has a base and a space for passing a strip through the upper surface of the base. And a first and a second strip upper surface applying roll unit for applying the paint of the strip in a state in which the first and second strip upper surface applying roll units are coated with the first and second strip upper surface applying roll units, And the upper surface of the base is selectively reciprocally movable on the upper surface of the base so as to selectively contact the upper surface of the strip in accordance with the color change of the paint applied on the upper surface of the strip.

Description

U-wrap dual-head paint coater of strip continuous color coating line {A STEEL STRIP COATING LINE}

The present invention relates to a coater apparatus for applying paint to upper and lower surfaces of a strip in a strip continuous color coating line, and more particularly to a coater apparatus for applying a paint to an upper surface of a strip, To a U-wrap dual-head paint coater of a strip continuous color coating line for selectively using a roll unit when arranging a plurality of nozzles in a single color to change the color of the paint.

Generally, CCL (continuous color coating line) that produces precoated metal (PCM) steel sheet is manufactured by pay off reel => Joiner (device connecting the top end of the preceding coil to the tail end of the trailing coil) =>> Entry accumulator => Cleaning section => Chemical coater => Chemical dryer => Prime coater (Chemical drying equipment) => Prime Oven => Prime Oven => Prime water quench => Finish coater => Finish Oven (top paint using hot air) => Finish water quench => Exit accumulator => Tension off reel (coil winding device).

On the other hand, the general appearance of the Prime coater and the Finish coater, which are important devices for producing CCL products, is exemplified by the S-Wrap type shown in FIG.

As shown in FIG. 4, the S-Wrap type coater is coated on the strip 200 surrounding the outer surface of a large BUR. This BUR supports the strip and maintains the strip 200 very smoothly. Therefore, the painting process can be done very precisely. The Coater is designed to be very easy to operate and it is easy to see the top and bottom strips.

However, in the case of finishing coater for top coating of iron plate, the kind and color of paint are changed according to the demand of the customer. In case of producing one product of finish coater (500) as in the past, There is a problem that the productivity and workability are deteriorated because the long line is stopped for the purpose of, for example, a roll cleaning work for removing residual paint on the screen 400 and a replacement work of paint.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to solve the above-mentioned problems, and it is therefore an object of the present invention to provide a method of manufacturing a strip, in which a plurality of upper surface coating roll units, The present invention provides a U-wrap dual-head paint coater of a strip continuous color coating line which can be expected to improve workability and productivity by directly using the opposite roll unit when changing the color of the paint in the process of applying paint.

Another aspect of the present invention is to provide a U-wrap dual-head paint coater of a strip continuous color coating line in which a plurality of roll units are installed so as to face each other on a horizontal line so as to be operated at the same level.

Another aspect of the present invention is to provide a U-wrap dual-head paint coater of a strip continuous color coating line which can be operated even by a single worker.

Another object of the present invention is to provide a U-wrap dual-color strip-continuous color coating line that can be installed at a relatively low investment cost without being limited by the installation position by reducing the space required for installing the equipment through the horizontal arrangement structure of the apparatus. Head paint coater.

Another aspect of the present invention is to provide a U-wrap dual-head paint coater of a strip continuous color coating line in which strips can pass horizontally through an arrangement of turning rolls.

In order to accomplish the above objects, the present invention provides a U-wrap dual-head paint coater of a strip continuous color coating line, comprising: a base; And a first and a second strip upper surface applying roll unit for applying the paint of the strip in the same structure as the first and second strip upper surface applying roll units, wherein the first and second strip upper surface applying roll units are provided with different colors of paint And the upper surface of the strip is selectively reciprocally movable on the upper surface of the base in a state that the upper surface of the strip is selectively contacted with the upper surface of the strip in accordance with the color change of the paint applied to the upper surface of the strip.

The first strip upper surface coating roll unit is provided on one side of the upper surface of the base, and includes a reciprocating unit for reciprocating forward and backward by the power of a driving cylinder, A pick-up roll in which the paint contained in the paint catch pan is buried, and an applicator roll which is in contact with one side of the pick-up roll and applies paint on the upper surface of the strip, desirable.

Preferably, first and second backup rolls for supporting the strip are installed in the space between the first and second strip upper surface coating roll units.

The strips 200 are horizontally arranged in the space between the first and second strip upper surface coating roll units 20 and 40 at the top and one side of the first and second strip top surface coating roll units 20 and 40, And the first to fourth turning rolls 60, 62, 64, and 66 that pass through the first to fourth turning rollers 60, 62, 64, and 66.

A guide table 80 is installed on one side of the first and second turning rolls 60 and 62 and the guide table 80 is rotated in a 90 ° direction through a worm reducer 82 provided at an upper end of the guide table 80 It is preferable to support the deflection of the strip 200 passing through the first to fourth turning rolls 60, 62, 64, 66.

The present invention is characterized in that a plurality of upper roll roll units for applying a paint to the top of a strip are arranged facing each other so as to apply paint to the upper surface of the strip with one roll unit, The roll unit located at the right side of the strip is directly brought into contact with the strip to apply the paint having the different color, so that the workability and the productivity can be improved by changing the color of the paint.

In addition, since the roll units are installed so as to face each other on the horizontal line so that they can be operated at the same level, the space required for equipment installation can be reduced, and the equipment can be installed at a relatively low investment cost without being limited by the installation position. It is possible to reduce the production cost by reducing the labor cost.
