Description
Technical field
The present invention relates to a kind of Coil Coating Products of changing different coating colors, coating type of can not shutting down and produce continuously applying device.
Background technology
The insider knows, so-called color painted steel strip (abbreviation Coil Coating Products) refers to by the continuous-output machine group at the resulting a kind of precoated shet goods of steel substrate external coating organic coating, the coloring that its existing organic polymer is good, mouldability, corrosion resistance and ornamental, the high strength and the workability energy that have again steel plate, be high technology content, the high value added product of steel industry, be widely used in the industries such as building, household electrical appliances, automobile and light industry.
The anti-corrosive properties of Coil Coating Products, durability, ageing resistance etc. depend primarily on the performance of coating, and its coating commonly used has epoxy coating, polyester coating, silicon modified polyesters coating, fluorocarbon resin coating, acrylate paint etc.At present, based on the rolling method of applying device shown in Figure 2 the coating that is Coil Coating Products produce in most widely used technology, account for 85%～90%.Referring to Fig. 1, shown in Figure 2, its coated technique process is: by the pretreatment of steel substrate 40 (also claiming steel band) process, namely pass through successively electrogalvanizing aluminium alloy layer 41, the steel band of coating chemical conversion layer 42 is advanced around guide roller 1 and coating backing roll 2, carrying roller 5 is by rotating the liquid primer base constantly picked in coating pond 9, coated roller 6 by applying coating to a side surface of steel substrate, then, enter the curing oven heated baking, solvent in coating is volatilized away fully, form primary coat 43 (also claiming priming paint), and solvent-laden waste gas is discharged and delivered to the incinerator processing, coating is cooling through shrend again after baking-curing, heated-air drying, then, the coating of changing coating pond is finish paint coating, and the steel band after just priming is repeated to above-mentioned steps, forms the rear Coil Coating Products that obtains of smart coating 44 (also claiming finish paint).
Along with developing rapidly and the reproducible raising of exploitation, painting color of new function coating of coatings industry, the variety of Coil Coating Products is increasing, need in the applying coating process of Coil Coating Products, change different painting colors and dissimilar color and the style requirement of coating to meet product, thereby most of coating production line need to repeatedly be changed the color of coating every day.The applying coating of steel band, baking operation continuously under high speed while producing due to Coil Coating Products, how can not shut down replacing coating is to improve Coil Coating Products production efficiency and quality problem in the urgent need to address.In addition, current coating pond can not be controlled liquid level, thereby can not control the band liquid measure of carrying roller, and the band liquid measure affects coating quality very little, too many and can drip extension, causes waste.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of just Coil Coating Products of replaceable different coating color, coating type of not shutting down to produce continuously applying device.
For solving the problems of the technologies described above, the technical solution used in the present invention is: Coil Coating Products is produced applying device continuously, comprise: frame, on frame, be disposed with guide roller and at least one pair of coating backing roll from bottom to top, but a side of each coating backing roll is provided with the painting roller mechanism that a set of along continuous straight runs moves, its structure comprises: the paint roller support that is arranged on the paint roller translation driving device on frame and is driven by the paint roller translation driving device, on the paint roller support, be provided with the application roll and the carrying roller that are parallel to each other, wherein, application roll is near corresponding coating backing roll; Below carrying roller, be provided with coating pond.
For certain coating backing roll, when guide roller is close to its below, this coating backing roll near a side of corresponding application roll along the line with the opposite side edge of this guide roller or with the angle of horizontal plane≤78 degree, when another coating backing roll was close to its below, this coating backing roll was near a side edge and the line on the mutually same side edge of described another coating backing roll and the angle of horizontal plane≤78 degree of corresponding application roll.
The difference of adjacent angle is not more than 5 degree in twos.
Described carrying roller staggers in the vertical direction mutually with corresponding application roll.
The line of centres between described carrying roller and corresponding application roll and the angle between horizontal plane are between 25～35 °, and the best is 30 °.
The top of described coating pond offers overfall.
The invention has the beneficial effects as follows: the painting roller mechanism that the present invention matches by least one pair of coating backing roll and each coating backing roll are set; a plurality of painting roller mechanism alternation during work; realized when the different coating colors of replacing, coating type apply shutting down, greatly improved production efficiency.In addition, by control, be positioned at coating backing roll and coating backing roll and the guide roller position relationship in the horizontal direction of upper and lower, make advancing of steel substrate very smooth and easy, and increased the time of contact of coating backing roll and steel substrate, make application roll have the sufficient time that paint is coated on steel band, improved coating quality.In addition, by coating pond top, offering the liquid level of overfall in controlling coating pond, thereby can control the band liquid measure of carrying roller, namely guarantee coating quality, avoid again dripping because coating content is on the high side and hung the waste caused.
