The utility model is just against the beneficial effect of roll-coater: by arranging the first applicator roll and second applicator roll of just reverse complementation rotation on coating machine, and make the rotating speed of the first applicator roll be greater than the rotating speed of the second applicator roll, thus it is good that the product effect surface made can be made to paint richness, flatness is good, be particularly suitable for the large-sized sheet material doing ornament materials, product percent of pass is up to 99%, and production efficiency will promote 20% than common coating machine; And the paint used is pure solid content UV paints, paint having no volatile substances, reduces human injury, energy-conserving and environment-protective, promotes operating efficiency.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the utility model is just described in further detail against roll-coater.
Refer to Fig. 1 and Fig. 2, one is just against roll-coater, for carrying out roller coating paint to the surface of furniture-plates sheet material, it comprises a workbench 10, one end of workbench 10 forms material loading end 11, and the other end forms transmission end 12, the top of workbench 10 be also provided with one for by sheet material 60 in the horizontal direction from material loading end 11 transmit towards transmission end 12 transmission crawler belt 20, sheet material 60 is arranged on the top of crawler belt 20, and the lower surface of sheet material 60 is close to the upper surface of crawler belt 20.
This coating machine also comprises the first applicator roll 30 and the second applicator roll 40 arranged in parallel interval, first applicator roll 30 is near transmission end 12, second coating 40 rollers are near material loading end 11, the upper surface of sheet material 60 can be close to the lateral wall of the first applicator roll 30 and the second applicator roll 40, first applicator roll 30 and the incorgruous rotation at work of the second applicator roll 40, to make sheet material 60 surface below the first applicator roll 30 and the second applicator roll 40 successively by with each roller coat in different directions one time, and, the rotating speed of the first applicator roll 30 is greater than the rotating speed of the second applicator roll 40, in the process that sheet material 60 transmits, the direction of the direction of the frictional force F1 between the first applicator roll 30 and sheet material 60 and the frictional force F2 between the second applicator roll 40 and sheet material 60 is incorgruous, wherein, first applicator roll 30 is contrary by the direction of transmitting with sheet material 60 with the direction of frictional force F1 between sheet material 60, therefore, can enable paint on the first applicator roll 30 and the second applicator roll 40 more fully roller coating on the surface of sheet material 60, thus ensure the paint thickness on sheet material 60 surface.
Preferably, for ensureing the problems such as sheet material 60 can not produce displacement in the process transmitted, card pauses, slippage, paint corrugate, the speed discrepancy of the first applicator roll 30 and the second applicator roll 40 can obtain an optimum value according to different sheet material 60 respectively by the test of limited number of time, thus the frictional force between the first applicator roll 30 and sheet material 60 is greater than the frictional force between the second applicator roll 40 and sheet material 60, therefore, all the time be there is stable frictional force by the process that transmits in sheet material 60, so can make sheet material 60 can evenly at the uniform velocity be transferred out.
First applicator roll 30 is identical with the second applicator roll 40 diameter, and its one end is coaxially fixed with the first travelling gear 13 and the second travelling gear 14, first travelling gear 13 and the second travelling gear 14 respectively and drives rotation respectively by the first motor 131 and the second motor 141.
In addition, the first electric light wheel 31 and the second electric light wheel 41 is respectively arranged with in the outside that the first applicator roll 30 is relative with the second applicator roll 40, first electric light wheel 31 and the second electric light wheel 41 are arranged with the first applicator roll 30 and tangent incorgruous rotation of the second applicator roll 40 respectively, 31 tangent angles are taken turns at the first applicator roll 30 and the first electric light, and second applicator roll 40 and the second electric light take turns 41 tangent angles and form V-type groove for holding paint respectively, one is provided with for exporting the paint efferent duct 50 of paint above V-type groove, paint and flow in described V-type groove through paint efferent duct 50, because the mobility of paint, and under the rotary action of applicator roll, paint evenly can be coated on the outer surface of the first applicator roll 30 and the second applicator roll 40.
To sum up, the utility model is just against roll-coater, by arranging the first applicator roll and second applicator roll of just reverse complementation rotation on coating machine, and make the rotating speed of the first applicator roll be greater than the rotating speed of the second applicator roll, thus cocoa completes the roll coating process to sheet material twice different directions simultaneously, make the product surface made paint richness good, flatness is good, be particularly suitable for the large-sized sheet material doing ornament materials, product percent of pass is up to 99%, and production efficiency will promote 20% than common coating machine; And the paint used is pure solid content UV paints, paint having no volatile substances, reduces human injury, energy-conserving and environment-protective, promotes operating efficiency.
Although carry out in conjunction with above specific embodiment description of the present utility model, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all like this substitute, improve and change be all included in the spirit and scope of attached claim.
