A kind of coupling surface paint application device
Technical field
The utility model belongs to the coating machine field, relates in particular to a kind of coating unit that petroleum pipeline connects coupling surface paint that is used for.
Background technology
Box cupling is that petroleum pipeline is gone into the well and connected requisite heavy connection.In box cupling was produced, the coated technique of coupling surface paint mainly adopted spraying and applies two kinds.At present, most enterprises all adopt spraying coating process, and when spraying because the paint atomizing, so highly volatile, not only the utilization rate and the rate of recovery are lower, and the paint that atomizes in the spraying process can cause severe contamination to environment, directly influence the healthy of operating personnel.Though and the employing coating processes can reduce above-mentioned defective, coating efficiency is lower, and the uniformity coefficient that applies is relatively poor, influences the quality of coupling surface paint application.
Summary of the invention
The utility model aims to provide a kind of simple and practical, can guarantee coupling surface paint application quality, improves the paint utilization rate, reduces the coupling surface paint application device of environmental pollution.
For this reason, the solution taked of the utility model is:
A kind of coupling surface paint application device is characterized in that, is made up of drive roll, driven voller, paint case, belt pulley, motor and reductor; Be set side by side with a drive roll and a driven voller in paint case upper edge, drive roll one end connects big belt pulley, and big belt pulley is connected reductor and motor through belt with small belt pulley.
Said drive roll and driven voller and paint case junction are inlaid with bearing holder (housing, cover).
Said big belt pulley diameter is ¢ 150mm, and the small belt pulley diameter is ¢ 15mm.
Method for using of the utility model and effect are:
Before the coating, earlier box cupling is placed between drive roll and the driven voller, behind the starter motor, drive roll relies on the frictional force of the body of roll will drive the box cupling uniform rotation, and the painter is dipping in even brushing of the paint that paint in the case and gets final product at coupling surface with covering with paint or varnish.Because box cupling is in rotary state all the time, can make more evenly putting in place of paint application, the oil droplet of drippage can directly be fallen in the paint case; Both avoided the atomizing volatilization of paint, reduced pollution, oil dripping is reclaimed fully environment; Improve the utilization rate of paint, reduce applying cost.
Description of drawings
Accompanying drawing is a coupling surface paint application apparatus structure stereogram.
Among the figure: motor 1, reductor 2, small belt pulley 3, belt 4, big belt pulley 5, drive roll 6, box cupling 7, driven voller 8, paint case 9, bearing holder (housing, cover) 10.
The specific embodiment
Visible by accompanying drawing, the coupling surface paint application device of the utility model mainly is made up of motor 1, reductor 2, small belt pulley 3, belt 4, big belt pulley 5, drive roll 6, driven voller 8 and 9 in case of paint.
Upper edge at 9 two broad sidewalls of paint case is symmetrily processed with two connecting holes respectively side by side; All be inlaid with bearing holder (housing, cover) 10 in four connecting holes; Drive roll 6 is installed in respectively in the bearing holder (housing, cover) 10 separately with driven voller 8 two ends; Distance between drive roll 6 and the driven voller 8 confirms according to the diameter of box cupling 7, and in general the diameter that is slightly less than box cupling 7 of the distance between drive roll 6 and driven voller 8 axis gets final product.
Be fixedly connected a big belt pulley 5 in the outer end of drive roll 6, big belt pulley 5 flexibly connects small belt pulley 3 through belt 4, and small belt pulley 3 is installed on the reductor 2 that is connected with motor 1.
Selecting motor 1 rotating speed for use is 1200r/min, and reductor 2 gearratios are 10:1, and big belt pulley 5 diameters are ¢ 150mm, and small belt pulley 3 diameters are ¢ 15mm.
