Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a spraying equipment for repairing a galvanized roller shaft. Background Art

[0002] Galvanized roller is a mechanical transmission device, mainly composed of bearings and rollers. It has high strength and corrosion resistance and is widely used in steel plate production lines in the fields of construction, home appliances, automobiles, etc. When the surface coating of the galvanized roller is worn or damaged, the exposed parts will easily rust, affecting the use effect. Therefore, the galvanized roller needs to be maintained regularly to improve performance and service life. At present, when doing maintenance work, most of them use manual spraying for repair. While there is a certain harm to human health, there are also differences in the repair effects under different technical levels; the few existing repair spraying equipment also have uneven spraying, and there are blind spots for spraying on galvanized rollers with lines or other concave and convex structures. Therefore, it is necessary to invent a galvanized roller repair spraying equipment that can replace manual repair spraying to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model describes a spraying equipment for repairing galvanized roller shafts, including a frame, the bottom of the frame is fixedly connected to a supporting leg, one end of the frame is fixedly connected to a fixed seat, and two supports are fixedly connected to the frame on the inner side of the fixed seat, the middle of the support is rotatably connected to a threaded block, the outer ring of the threaded block is connected to the motor transmission by gear meshing, the central thread of the threaded block is threadedly connected to a screw, one end of the screw passes through the fixed seat and is slidably connected to it, and the other end is fixedly connected to a first three-jaw chuck, and the other end of the frame is slidably connected to a second three-jaw chuck through a slide rail, the frame is located between the first three-jaw chuck and the second three-jaw chuck and is fixedly connected to a spray frame, and a spray gun is fixedly connected to the inside of the spray frame.

[0005] Furthermore, a material box is fixedly connected to the lower part of the frame, and the material box is fixedly connected to the input end of the pneumatic diaphragm pump through a pipeline, and the output end of the pneumatic diaphragm pump is connected to the spray gun through a material pipe.

[0006] Furthermore, at least three spray guns are fixedly connected to the inner side of the spray rack.

[0007] Furthermore, the motor and the pneumatic diaphragm pump are both controlled by a controller.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] The utility model moves the galvanized roller shaft that needs to be repaired by arranging a mechanism in which a screw and a screw block cooperate with each other, and then sprays and repairs it through a plurality of spray guns at different angles. The spraying is more uniform and there is no dead angle. The structure is simple and practical. The galvanized roller shaft that needs to be repaired can be firmly fixed by the first three-jaw chuck and the second three-jaw chuck, ensuring safety during the spray repair process. The three-jaw chuck can adapt to galvanized roller shafts of different diameters, which increases the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1 to 3 The spraying equipment for repairing a galvanized roller shaft shown in the figure includes a frame 1, a support leg 14 is fixedly connected to the bottom of the frame 1, a fixed seat 3 is fixedly connected to one end of the frame 1, two supports 13 are fixedly connected to the frame 1 on the inner side of the fixed seat 3, a threaded block 12 is rotatably connected in the middle of the support 13, the outer ring of the threaded block 12 is transmission connected to the motor 15 by gear meshing, a screw 2 is threadedly connected to the center of the threaded block 12, one end of the screw 2 passes through the fixed seat 3 and is slidably connected to it, and the other end is fixedly connected to the first three-jaw chuck 4, and the other end of the frame 1 is slidably connected to the second three-jaw chuck 7 through the slide rail 8, the frame 1 is located between the first three-jaw chuck 4 and the second three-jaw chuck 7 and is fixedly connected to a spray frame 6, a spray gun 601 is fixedly connected to the inner side of the spray frame 6, and the two ends of the galvanized roller shaft 5 to be repaired can be installed on the first three-jaw chuck 4 and the second three-jaw chuck 7.

[0016] In order to make spraying more convenient and to effectively utilize the paint, a material box 9 is fixedly connected to the lower part of the frame 1. The material box 9 is fixedly connected to the input end of the pneumatic diaphragm pump 10 through a pipeline, and the output end of the pneumatic diaphragm pump 10 is connected to the spray gun 601 through the material pipe 11.
