Abstract
The utility model relates to a coater, comprising an anilox roller (1), a rubber roller (3) and a baking channel; the anilox roller (1) and the rubber roller (3) are correspondingly arranged and are provided with a clearance where the coating material can pass through; the baking channel sequentially comprises a low temperature baking channel (6) and a high temperature baking channel (9) along the conveying direction of the coating material; furthermore, the low temperature baking channel (6) is provided with at least an air outlet (8). Compared with the prior art, the utility model can eliminate or lighten the coating surface connecting film and problem of brume-shape generation, and improves the quality of the coating products.
Description
Technical field
The utility model relates to a kind of coating machine, particularly relates to a kind of coating machine with low temperature drying tunnel and high temperature drying tunnel.
Background technology
Liquid coating is coated on the base material can form the coated article with specific surface properties by coating machine, and this technology has been widely used in industrial every field.According to different coated products and coating process, coating machine can have various forms or structure, wherein a kind of coating machine comprises an anilox roll, and liquid coating is pressed certain surface linear velocity (as 150-200m/min) and certain coating weight (as 5-8g/m by anilox roll
2) evenly coat on the substrate surface, make coating be distributed in the whole surface of base material then, and it is even more good more to distribute, and makes the base material that scribbles coating pass through drying tunnel afterwards, with coated and dried, thus obtain coating evenly, surface-brightening, the coated article of conjunctiva not.
Domestic and international electrochemical aluminium coating machine adopts the anilox roll coating method more at present, be coated with material is entered drying tunnel 120-160 ℃ by normal temperature high temperature after the coating, the coating surface fast drying, produce surperficial conjunctiva, if air humidity big (particularly south), coating contact aqueous vapor, it is vaporific that coating is produced, and has a strong impact on product quality.
The content of utility model
The purpose of this utility model is exactly the above-mentioned deficiency that overcomes prior art, and a kind of novel coating machine is provided, and eliminates or alleviates case-hardening and produce vaporific problem, improves the quality of products.
Coating machine of the present utility model comprises anilox roll, rubber rollers and drying tunnel, anilox roll and rubber rollers are oppositely arranged, has the gap that coating material is passed through therebetween, described drying tunnel sequentially comprises low temperature drying tunnel and high temperature drying tunnel along the throughput direction of coating material, and described low temperature drying tunnel has at least one exhaust outlet.
In the low temperature drying tunnel, because temperature is lower, the dry tack free of coating is slow, the inside and outside rate of drying of coating is reached unanimity, in addition, because the low temperature drying tunnel has air discharge structure, can reduce the influence of environment (or air) humidity to the coating drying, it is vaporific to avoid coating to produce.So the utility model is compared with prior art, can improve the quality of products.
Describe the utility model in detail with embodiment with reference to the accompanying drawings.
Description of drawings
Fig. 1 is the partial schematic diagram of the utility model coating machine.
Each label is represented in the accompanying drawing: 1 anilox roll, 2 dancer rools, 3 rubber rollers, 4 levelling sections, 5 electrothermal tubes, 6 low temperature drying tunnels, 7 housings, 8 exhaust outlets, 9 high temperature drying tunnels.
The specific embodiment
As shown in the figure, coating machine of the present utility model comprises anilox roll 1, rubber rollers 3 and drying tunnel, anilox roll 1 and rubber rollers 3 are oppositely arranged, has the gap that coating material is passed through therebetween, described drying tunnel sequentially comprises low temperature drying tunnel 6 and high temperature drying tunnel 9 along the throughput direction of coating material, and described low temperature drying tunnel 6 has at least one exhaust outlet 8.
In the low temperature drying tunnel, because temperature is lower, the dry tack free of coating is slow, the inside and outside rate of drying of coating is reached unanimity, in addition, because the low temperature drying tunnel has air discharge structure, can reduce the influence of environment (or air) humidity to the coating drying, it is vaporific to avoid coating to produce.So the utility model is compared with prior art, can improve the quality of products.
On the basis of the above, the utility model can also have following modification:
1, has Far-infrared Heating mechanism in the described low temperature drying tunnel 6.Far-infrared Heating mechanism can make the inside and outside heating, drying simultaneously of coating, avoids the conjunctiva defective of coating surface better.
2, in above-mentioned modification 1, described Far-infrared Heating mechanism can have electrothermal tube 5.
3, on the basis of above-mentioned modification, described coating machine can have a vertical levelling section 4 in the downstream of anilox roll, and described low temperature drying tunnel 6 is in the downstream of described levelling section 4.Because of there is the site in anilox roll, make coating have the invisible site of naked eyes, greatly influence the quality of product.Levelling section 4 is set can eliminates the coating site, because liquid coating has certain fluidity, coating back base material rises with certain linear velocity, and the coating site is eliminated under gravity and capillary effect, can form the coating of surfacing, light.
4, have on the basis of a vertical levelling section 4 at coating machine, described low temperature drying tunnel 6 can be the part of described vertical levelling section 4, and this part is limited by a housing 7.This modification needn't be provided with a low temperature drying tunnel separately, but low temperature drying tunnel and levelling section are combined, thereby simplifies the structure, and has saved the space.
5, on the basis of modification 4, described exhaust outlet 8 is preferably disposed on the top of low temperature drying tunnel 6.This structure more helps getting rid of moisture or the moisture in the low temperature drying tunnel.
6, in order to regulate, a dancer rools 2 can be set at the lower end position of described levelling section 4 from the coated substrate of anilox roll output.
Above-mentioned just illustrative to the description of utility model with reference to drawings and Examples, and do not constitute qualification to it.Obviously, on basis of the present utility model, can carry out many modification, but not break away from claim of the present utility model essence required for protection.
