There is not the automatic spray apparatus of intersection
The utility model relates to a kind of automatic spraying equipment, and the outer automatic spraying equipment of especially a kind of case is particularly suitable for spraying automatically outward with the case of doing container.
Though, box outer surface is sprayed, especially the case outer surface to container sprays, and has realized automation already, adopts automatic spraying equipment to reduce working strength of workers, and coating quality increases.But, be the netted spraying that intersects because existing automatic spraying equipment adopts, what be sprayed on that tank surface walks is sigmoid curve, makes sprayed surface blind area or overlay region must occur, and the film thickness of blind area is not enough, and the overlay region is then super thick.Therefore, the use of existing automatic spraying equipment, its paint consumption and hand spray are about the same, do not save to some extent.For this reason, designer of the present utility model has carried out sufficient observation, understanding and analysis to automatic spraying equipment, reaches a conclusion: the track of spraying is improper to be the basic reason that causes painting a large amount of wastes.
The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, and it is scientific and reasonable to propose a kind of spraying profile, overcomes blind area and overlay region, the nothing intersection automatic spray apparatus that paint is rationally used.
Realize the technical scheme of above-mentioned purpose: a kind of nothing intersection automatic spray apparatus, comprise spray gun, support and cart, vertical guide rail is arranged in the cart, cart places on the horizontal guide rail, it is characterized in that: be provided with the velocity compensation device reverse with large vehicle walking speed constant speed, the velocity compensation device is by guide rod, drive, transmission case and power set are formed, the output of power set connects drive, the bilateral symmetry of drive drives the guide rod of rightabout motion each other, guide rod is slidably supported in the transmission case, end at the different guide rods of a homonymy is fixed with spray gun through support, and the velocity compensation device places on the vertical guide rail of cart by its transmission case.
Power set are motor, the drive of motor in coupling spindle drives transmission case.
Drive is a duplex chain wheel, the chain two ends of walking around row's sprocket wheel are fixedly connected with two ends of the different guide rods of a side that are fixed with spray gun, the chain two ends of walking around another row's sprocket wheel are fixedly connected with two ends of the different guide rods of opposite side, and double-stranded bar is hidden in the guide rod of hollow out.
Drive is a gear, the inboard of drive both sides guide rod have can with the linear gear rack of gears engaged.
Power set are motor.
Power set are cylinder.
Power set are oil cylinder.
Spray gun fixing on the support of each guide rod is two.
Guide rod places in the protective cover, is provided with near switch in the guide rod one end protective cover that does not have spray gun.
Adopt such scheme, the tangible technique effect of the utility model is: 1, owing to introduce and the reverse velocity compensation device of large vehicle walking speed constant speed, offset the influence of large vehicle walking to spraying, spray gun for the horizontal direction of tank surface for static relatively, spray gun is only done the straight line spraying of vertical direction in tank surface, overcome the deficiency of existing intersection spraying technology, avoided blind area and overlapping superthick area, made paint be able to abundant reasonable use.2, show through theory calculating and measured data, adopt the utility model can save paint more than 15%, can be about about 1,500 ten thousand yuan of company's saving paint expense in 1 year, economic benefit improves greatly.3, because the utility model adopts two groups of spray gun alternations, make and respectively organize spray gun the process that cools is arranged, nozzle is unlikely to because of continuous operation causes high temperature deformation, and the accumulative total working life of spray gun significantly prolongs.
Below by embodiment, in conjunction with the accompanying drawings, be further described:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the A-A profile among Fig. 1.
Embodiment: in conjunction with Fig. 1 and Fig. 2, a kind of nothing intersection automatic spray apparatus comprises four spray guns 1, support 2, cart 10 and velocity compensation device.The velocity compensation device is by two guide rods 3, drive 6, transmission case 4 and power set are formed, power set are motor 8, the drive 6 that motor 8 drives in the transmission case 4 through coupling spindle 5, drive 6 is a duplex chain wheel, walk around one row sprocket wheel 6 a chain 13 two ends be fixed with spray gun (1-1 through support 2, two ends of the different guide rods 3 of side 1-2) are fixedly connected, two ends of the different guide rods 3 with opposite side in two ends of another root chain 12 of walking around another row's sprocket wheel 6 are fixedly connected, double-stranded bar (12,13) be hidden in the guide rod 3 of hollow out, guide rod 3 is slidably supported in the transmission case 4, and the greatest limit width between two supports 2 should equal the effective spraying width of two spray gun 1-2 on the guide rod 3.The velocity compensation device places on the vertical guide rail 9 in the cart 10 by its transmission case 4, cart 10 places on the horizontal guide rail 11, guide rod 3 places in the protective cover 7, isolate the pollution of paint, in the guide rod 3 one end protective covers 7 that do not have spray gun 1, be provided with near switch 14, be used for starter motor near switch 14, guarantee before spraying beginning, make two on the guide rod 3 spray gun 1-1 and 1-2 between be in the greatest limit width position.
Speed is set: the vertical spraying rate (also being the speed of service of velocity compensation device on the vertical guide rail direction) of at first setting spray gun 1, high computational according to casing once sprays required time, the effective width that once sprays with two spray guns 1 is the setting speed of travel of cart 10 divided by above-mentioned time gained speed V then, also is the speed of service of the guide rod 3 set of power set.
The course of work: be in the greatest limit width position shown in Fig. 1 by make two guide rods 3 near switch 14, according to above-mentioned setting speed, start simultaneously: 1, cart 10 is pressed setting speed V and is walked on horizontal guide rail 11; 2, motor 8 drives with big 10 garages through the both sides of duplex chain wheel 6 chain (12,13) symmetry and walks that speed equates but mutual heterodromous different guide rods, rightabout motion, both speed of walking to cart 10 with speed V of the spray gun 1-2 that is spraying are offseted, and spray gun 1-2 is in the horizontal direction for static relatively; On the other hand, the guide rod 3 that is fixed with spray gun 1-1 is moved with speed V to cart, promptly move in the horizontal direction with the speed of 2V; 3, spray gun 1-2 begins carrying out the straight line spraying of setting speed on the vertical direction of tank surface.When the straight line spraying of setting height is finished, spray gun 1-2 covered 2 times once effectively spray width, arrive preparation spraying position next time, at this moment, the motor counter-rotating of vertical spraying motor and velocity compensation device, spray gun 1-2 begins downward spraying, the straight line spraying of a beginning new round, overcome the appearance of blind area and overlapping superthick area, paint is fully utilized.
In the present embodiment, drive also can adopt gear drive except adopting chain gear transmission, the inboard of drive both sides guide rod open can with the linear gear rack of gears engaged.
Drive also can adopt other symmetry to drive the structure that the different guide rods in both sides are done rightabout motion each other.
Fixing spray gun number can be two on the different guide rods, also can be one or more, according to different spraying needs, is provided with according to circumstances.At this moment, the speed of service of guide rod and cart is adjusted accordingly according to different effective spraying width.
Power set can be existing power set such as gas motor, hydraulic motor, cylinder, oil cylinder.
