Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a steel structure profile spraying device. Background Technology

[0002] Steel structure refers to a structural form that can bear and transmit loads, made of steel plates and hot-rolled, cold-bent or welded profiles connected by connectors.

[0003] Steel structures are made by connecting profiles. Before use, the profiles need to be cut to the required length, and the surface of the profiles needs to be derusted, then a paint layer is sprayed for rust prevention, and the color needs to be matched for different occasions. Currently, most profile painting is done by brushing, which is slow and the paint layer thickness is uneven. Therefore, this application discloses a profile painting device for steel structures. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a steel structure profile painting device.

[0005] This utility model is achieved through the following technical solution: a steel structure profile painting device, including a frame, on which several rollers are spaced apart, one of which is connected to a pulley at its outer end, the pulley is connected to a main wheel via a conveyor belt, the main wheel is connected to the output shaft of a motor, the motor is mounted below the frame, a nozzle is provided directly above the roller connected to the pulley, the nozzle is connected to the lower part of the spray pipe, one end of the hose is connected to a quick connector at the lower end of the spray pipe, the other end of the hose is connected to a connector on the pump body, the pump body is connected to the paint tank through a pipe, and the spray pipe is connected to a support rod via a clamp, the support rod is vertically connected to the frame.

[0006] As a further improvement to the above solution, the pulley is connected to the middle roller among several rollers, so that one of the rollers is powered, and the powered roller in the middle can effectively transport the profile through directly below the nozzle.

[0007] As a further improvement to the above solution, the pipe connecting the pump body to the paint tank extends to the bottom of the paint tank, allowing the paint liquid inside the tank to be completely sucked up through the pipe, thus preventing the paint liquid at the bottom of the paint tank from not being sucked up.

[0008] As a further improvement to the above solution, a photoelectric sensor is snapped onto the support rod, and the photoelectric sensor is located on one side of the pulley. The photoelectric sensor detects that there is a conveyed profile on the roller connected to the pulley, and the photoelectric sensor sends a signal.

[0009] As a further improvement to the above solution, guide baffles are symmetrically arranged on both sides of the frame to prevent the profiles conveyed on the rollers from falling off and affecting the normal painting process of the profiles.

[0010] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The roller installed in the middle of the frame is driven by a motor to rotate. Multiple rollers support the profile and the profile is transported by powered rollers. At the same time, a photoelectric sensor transmits a signal to control the pump to work, drawing paint from the paint tank and spraying it from the nozzle onto the top and sides of the profile. The spraying speed is fast, the paint layer is uniform, and the spraying effect is good. Attached Figure Description

[0013] Figure 3 This is a schematic diagram of the installation structure for spray painting. Detailed Implementation

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

[0015] like Figures 1 to 3 As shown, a steel structure profile painting device includes a frame 1. Several rollers 2 are spaced apart on the frame 1. One of the rollers 2 is connected to a pulley 6 at its outer end. The pulley 6 is connected to a main wheel 4 via a conveyor belt 3. The main wheel 4 is connected to the output shaft of a servo motor 5. The servo motor 5 is installed below the frame 1. A nozzle 12 is arranged directly above the roller 2 connected to the pulley 6. The nozzle 12 is connected to the lower part of the spray pipe 11. The lower end of the spray pipe 11 is connected to one end of a flexible hose 10 via a quick-connect plug. The other end of the flexible hose 10 is connected to a connector on a pump body 9. The pump body 9 is connected to a paint tank 8 via a pipe. The paint tank 8 is located inside a side frame 7. The side frame 7 is connected to one side of the frame. The spray pipe 11 is connected to a support rod 14 via a clamp 13. The support rod 14 is vertically connected to the side frame 7.

[0016] As a further improvement to the above solution, the pulley 6 is connected to the middle roller 2 among a plurality of rollers 2, so that one of the rollers 2 is powered, and the powered roller 2 located in the middle can effectively convey the profile through the nozzle 12 directly below.

[0017] As a further improvement to the above solution, the pipe connecting the pump body 9 to the paint tank 8 extends into the bottom of the paint tank 8, which can suck up all the paint liquid in the paint tank 8 through the pipe, thus avoiding the paint liquid at the bottom of the paint tank 8 not being sucked up.

[0018] As a further improvement to the above solution, a photoelectric sensor 15 is snapped onto the support rod 14, and the photoelectric sensor 15 is located on one side of the pulley 6. The photoelectric sensor 15 detects that there is a profile being conveyed on the roller 2 connected to the pulley 6, and the photoelectric sensor 15 sends a signal.

[0019] As a further improvement to the above solution, guide baffles 16 are symmetrically arranged on both sides of the frame 1 to prevent the profiles conveyed on the rollers 2 from falling off and affecting the normal painting work of the profiles.

[0020] As a further improvement to the above solution, the top of the paint box 8 is provided with a feeding port, and a box cover 17 is threadedly connected to the feeding port.

[0021] The working principle of a steel structure profile painting device is as follows: First, the profile is placed on roller 2, supported by multiple rollers 2, and one end of the profile is placed on roller 2 connected to pulley 6. Then, the roller 2 installed in the middle of the frame 1 is driven to rotate by servo motor 5, and the profile is transported by the powered roller 2. At the same time, the photoelectric sensor 15 transmits signals to control the pump body 9 to work, drawing paint liquid from the paint tank 8 and spraying it from the nozzle 12 onto the top and sides of the profile, so that the profile is coated with paint during the conveying displacement. Then, the profile is flipped over, and the servo motor 5 is reversed to make the profile return to the original displacement and spray the original lower surface of the profile upward.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
