The non-contact type high-precision coating machine is characterized in that the turning roll device comprises a first turning roll and a second turning roll; at least partial bottom of the material supplying device is in a shape of an inner cylindrical surface; the material supplying device is arranged above the first turning roll; a cylindrical surface film-drawing cavity is formed by the inner cylindrical surface of the material supplying device and a cylindrical roll surface of the first turning roll; a charging groove is formed in the upper part of the material supplying device; the bottom of the charging groove is provided with overflowing holes at intervals along the width direction of band steel and is communicated with the cylindrical surface film-drawing cavity. According to the non-contact type high-precision coating machine, the cylindrical surface film-drawing cavity is arranged to be contacted with the band steel with different speeds, so that on the one hand, high-precision coatings with the different thicknesses are formed by controlling a speed drawing die; on the other hand, adverse influences to equipment by an additional force and deformation generated by the contact of the equipment in the coating process are avoided, so as to be good for improving the stability of the coating process and further prolong the service life of the equipment.
Description
Technical field
The utility model relates to the technical field with the steel coating plant equipment, particularly the non-contact type high-precision coating machine.
Background technology
Coil Coating Products is the ultimate product of world today iron and steel enterprise sheet material deep processing, has lightweight, characteristics and the good Corrosion Protection such as attractive in appearance, is widely used in the industries such as building, light industry, household electrical appliances.In recent years, along with the development of these industries and the raising of the level of consumption, its market demand increases very fast, has therefore attracted domestic large quantities of enterprise to build or Bus in Color Coat Production Line under construction.
The technique of producing in the world coloured painted coat steel plate mainly contains rolling method, curtain stream method and powder and is coated with method.
Rolling method is a kind of comparative maturity of current production Coil Coating Products, and the production technology generally adopted.Yet roll coater is because the roller coat process need is adjusted the pressure between each roller, gap and could realize more satisfactory coating with the speed ratio with steel, in actual production process, these affect the factor of coating quality, again directly the tape steel rotate the impact of some the row accidentalia such as shake that cause due to applicator roll in coating procedure from body shape, with steel, thereby cause the undesirable of final coating product.
Curtain stream method is to adopt curtain stream coating machine that liquid coating is coated onto to belt steel surface, and the band steel be coated with can not stay roll marks, controls difficulty large.Because this technique controlling difficulty is larger, only, in the monarch Jin Chang of Nippon Steel application, be not promoted.
Powder painting method is a kind of new technology, in Europe, with Japan, has the number cover to adopt the color coating unit operation of powered guns technology, and its process speed is low, and production capacity is little.
The utility model content
Technical problem to be solved in the utility model is that being provided at coating procedure floating coat machine for the technical problem existed in above-mentioned prior art does not contact with the strip, and can improve the coating surface quality and make roller be out of shape little non-contact type high-precision coating machine.
The technical scheme that the utility model adopts is: the non-contact type high-precision coating machine, it comprises feeding device, the slewing rollers device, it is characterized in that described slewing rollers device comprises the first slewing rollers and the second slewing rollers, at least part of bottom of described feeding device is the inner cylinder face shape, described feeding device is installed in the oblique upper of the first slewing rollers, the cylindrical roll surface of the inner cylinder face of described feeding device and the first slewing rollers forms cylinder membrane chamber, top at feeding device is provided with charge chute, being interval with flowing hole in the bottom of charge chute along the strip width direction is connected with cylinder membrane chamber.
By technique scheme, the face that rolls of the inner cylinder face of described feeding device and the first slewing rollers leaves equally spaced gap and forms cylinder membrane chamber.
By technique scheme, the spacing of the face that rolls of the inner cylinder face of described feeding device and the first slewing rollers is 0.15-0.6mm.
By technique scheme, described charge chute is square.
By technique scheme, the radian in described cylinder membrane chamber is 45 ° ~ 90 °.
By technique scheme, the roll body of described the first slewing rollers and the second slewing rollers is steel rider.
The obtained beneficial effect of the utility model is: 1, by cylinder membrane chamber is set, with the band steel of friction speed, contact, form the high-accuracy coating of different-thickness by the control rate drawing-die; 2, because application head does not contact with the strip, therefore can not produce additonal pressure to band steel and slewing rollers, the roller distortion is little, and the glacing flatness of roller own is high, can realize that like this cylinder drawing-die cavity-coating layers evenly applies along the strip width direction, and the coating surface quality is high; Avoid again the additional force that produces due to the contact between equipment and the distortion harmful effect to equipment in coating procedure, be conducive to improve the stability of coating procedure, and then extension device service life; 3, the utility model simple in structure, easy to operate, maintain easily, investment cost is few.
The accompanying drawing explanation
The front view of the embodiment that Fig. 1 provides for the utility model.
The left view that Fig. 2 is Fig. 1.
In figure: 1, feeding device, 2, charge chute, the 3, first slewing rollers, the 4, second slewing rollers, 5, flowing hole, 6 cylinder membrane chambeies.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1:
The structural representation of the embodiment that Fig. 1 and Fig. 2 provide for the utility model, from two figure, the non-contact type high-precision coating machine comprises feeding device 1, the slewing rollers device, described slewing rollers device comprises the first slewing rollers 3 and the second slewing rollers 4, at least part of bottom of described feeding device 1 is the inner cylinder face shape, described feeding device 1 is installed in the oblique upper of the first slewing rollers 1, the cylindrical roll surface of the inner cylinder face of described feeding device 1 and the first slewing rollers 3 leaves equally spaced gap and forms cylinder membrane chamber 6, be provided with square charge chute 2 on the top of feeding device, being interval with flowing hole 5 in the bottom of charge chute 2 along the strip width direction is connected with cylinder membrane chamber.
