The specific embodiment
Carry during work in the glue that rubber roll is immersed in lacquer disk(-sc), carry rubber roll glue is transferred on the applicator roll, applicator roll again with glue application to composite membrane, control roll is used for regulating submits to roller to transfer to the glue quantity of applicator roll, in order to control more accurately glue-spread.The direction of rotation of the applicator roll of this device is opposite with the traffic direction of composite, and the ratio of the linear velocity of the gap by regulating each roller, the speed of service of composite and applicator roll and utilize control roll can obtain required coating weight, the glued membrane of flat appearance.During the speed 100m/min of composite, the speed of carrying rubber roll is 120m/min, and the speed of applicator roll is 101m/min, the speed 5-10m/min of control roll.The coating weight of the tropical aluminium that such coating method is produced can reach the dried glue amount of 8-12g/m2, and the flat appearance of glued membrane can reach high compactness fully, and the sealing of solids content is reached reliable purpose.
The utility model in process of production, the speed of service of composite is very fast, for ensuring enough drying capacities, the baking oven of equipment generally is designed to 15-20m longbow shape drying tunnel, baking oven the inside tropical aluminium operation by the guide rolls support of actively operate.The first paragraph of baking oven and second segment adopt heated-air drying, can discharge a large amount of organic solvents like this.Consider that material is aluminium plastic composite material, the 3rd section of baking oven and the 4th section drying mode adopt hot blast to add the far-infrared ray drying mode, namely play the solidification to glue, be unlikely to again on the anti-sticking deflector roll of the plastic basis material melting on the tropical aluminium, the 5th section heat that directly siphons away in the baking oven of baking oven, in baking oven, blow a cold wind over, play the cooling effect to material for the 6th section.Temperature curve in the baking oven is 60 ℃, 120 ℃, 160 ℃, 200 ℃, 220 ℃.The solvent-laden hot blast of discharge is introduced the recovery chamber, reclaim mixed solvent, again mixed solvent is delivered to the useless mixed solvent of incinerator internal combustion, solvent becomes harmless water and carbon dioxide, and liberated heat draws to recycle between carriage return again dries glue.Enter at last solid particle footpath in the tail gas of atmosphere in PM2.5, reach the requirement of environmental protection.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model mainly is that what to solve by multiple roll coating is large coating weight problem, and the normally used coating method of our wrapping enterprise is single net roller coat cloth, and the net roller obtains anilox roll by several modes such as electric carving, laser carving, extruding rollers.The degree of depth of anilox roll, line number can determine the size of coating weight.But mesh is too dark, the too low meeting of line number causes crawling even, and the glue picture on the stock is the hills small hill one by one, can cause content poorly sealed, does not just reach the effect of sealing.
Specific implementation way of the present utility model is used the accurate coating method of 3 rollers exactly.Show that such as Fig. 1 individual heat-seal adhesive groove 1 is arranged, glue groove the inside fills a certain amount of heat-seal adhesive, and this heat-seal adhesive can only be used on tropical aluminium 6.Only having a rubber rollers to be immersed in the glue in the lacquer disk(-sc), this rubber roll glue is carried rubber roll.Carry rubber roll by cover AC frequency conversion servo system control and a driving, reach the purpose of accurate speed governing.Carrying rubber roll adhesive tape in the glue groove has a large amount of glue, and it is control roll by the roller that running runs into for the first time.Control roll and carry certain gap is arranged between the rubber roll, the gap between them is regulated gap, the left and right sides by precision lead screw and is reached uniformity.Control roll is opposite with the rotation direction of carrying rubber roll, and rotating speed differs 25 times, as when putting forward rubber roll speed and being 120m/min, the control roll rotating speed is 5-10m/min, and main purpose is to alleviate because the glue surface tension effects makes glue be the capable became uneven of wave carrying rubber roll.Control roll also is by an AC frequency conversion servo system control and drives.
Use procedure: the upper surface of carrying rubber roll is covered with the heat-seal adhesive of doses under the effect of control roll, glue can pass to applicator roll, and applicator roll and carry certain interval is arranged between the rubber roll is conveniently carried between rubber roll and the applicator roll without the friction running.Applicator roll is the dosage roller, the applicator roll surface is stained with thin and uniform heat-seal adhesive, heat-seal adhesive on the applicator roll is coated directly onto on the compound tropical aluminium surface, regulate applicator roll and carry rubber roll by precision ball screw, gap between applicator roll and the counter-pressure cylinder, the product of the coating weight that just can obtain wanting can be applied to the heat-seal adhesive that 12gsm does with the coating weight maximum on the aluminium of this coating method torrid zone, like this tropical aluminium and PVC seal, and tropical aluminium bubble-cap can reach the product of high dense seal effect.The content of product has high moistureproof, anti-oxidation, sun-proof, reaches the product of long-term shelf deposit.
As shown in Figure 2, tropical aluminium composite material consists of by four layers, is followed successively by from top to bottom nylon layer, compound adhesive water layer, composite layer and heat-sealing glue-line.
As shown in Figure 3, tropical aluminium composite material directly enters baking oven after finishing application step, and oven temperature is respectively 60 ℃ of first segments, 120 ℃ of second sections, 160 ℃ at the 3rd joint, 200 ℃ at the 4th joint, 220 ℃ at the 5th joint.It is finished product torrid zone aluminium composite material after the oven dry.
