Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing equipment, in particular to an automatic painting device for steel structure docking fasteners. Background Technique

[0002] In the field of steel structure buildings, docking fasteners play a crucial connecting role. However, there are many problems with traditional steel structure docking fasteners in terms of surface coating treatment. First of all, after the traditional steel structure docking fasteners are produced and demolded, it is necessary to apply an anti-rust paint film to strengthen the anti-rust effect of the structure. However, the traditional paint construction method generally uses manual brushing, which not only has a large labor intensity, but also has uneven coating thickness, and is prone to phenomena such as missed coating and running, affecting the protection effect and appearance quality. Moreover, due to the complex shape and structure of the steel structure docking fasteners, some corners and gaps are difficult to be fully covered by the paint, which is likely to become the starting point of corrosion. In actual use, this may lead to premature damage of the fasteners, affecting the overall stability and safety of the steel structure. Based on this, we designed an automatic paint equipment for steel structure fasteners to improve the integrity and efficiency during film covering. Content of the Utility Model

[0003] Aiming at the technical problems existing in the background technique, the utility model provides an automatic painting device for steel structure docking fasteners, which solves the problems of poor integrity and low working efficiency when applying anti-rust paint film to existing steel structure connectors.

Specific embodiments

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as upper, lower, left, right, front, rear, inner and outer that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0025] As Figures 1-6 shown, an automatic painting device for steel structure docking fasteners includes a fixed frame 1, a box body 5, and a stirring mechanism 6. The fixed frame 1 is a rectangular frame structure, and a box body 5 is arranged on the upper part of the fixed frame 1. The stirring mechanism 6 is arranged inside the box body 5. The stirring mechanism 6 includes a rotating drum 601, an auxiliary table 604, a tooth ring 602, an annular guide strip 603 and a first driving motor 2. The rotating drum 601 is connected to the bottom of the box body 5 through the auxiliary table 604. The tooth ring 602 on the outer wall of the rotating drum 601 is connected to the gear 11 on the output shaft of the first driving motor 2. The annular guide strip 603 is arranged inside the rotating drum 601. One end of the rotating drum 601 is provided with a feeding trough 8, and the other end of the rotating drum 601 is provided with a filtering trough 9.

[0026] It should be noted that after the steel structure fasteners are produced, in order to improve their corrosion resistance, an anti-rust layer needs to be applied to the surface of the steel structure fasteners. The existing coating method is generally achieved manually by soaking. This method requires a lot of labor and is not very efficient. Based on this, we have designed a device that can automate the film coating process to improve work efficiency. Inside the auxiliary table 604, there are several supporting rollers 605, and the supporting rollers 605 are connected to the outer wall of the rotating drum 601. Inside the box body 5, two partition plates 13 form an independent film coating chamber, and there are several through holes 606 on the rotating drum 601 inside the film coating chamber.

[0027] It should be further noted that our box body 5 is a rectangular cavity structure with openings at both ends, and a stirring mechanism 6 is arranged inside the box body 5. Among them, the rotating drum 601 is arranged inside the box body 5 through the auxiliary table 604, and two partition plates 13 inside the box body 5 form an independent film coating chamber, and paint is injected inside. During the rotation of the rotating drum 601, the film coating process of the internal steel structure fasteners is realized.

[0028] It should be further noted that in order to rotate the entire rotating drum 601, a first drive motor 2 is arranged outside the box body 5, and the output shaft of the first drive motor 2 is meshed and connected with the toothed ring 602 on the rotating drum 601 through a gear 11 to achieve driving.

[0029] It should be further noted that in order for the steel structure fasteners inside the rotating drum 601 to be guided from left to right when it rotates, a guiding strip 603 is designed inside the rotating drum 601, which can complete the guiding movement of the steel structure fasteners. Thus, when the steel structure fasteners pass through the film coating chamber, the paint enters from the through holes 606 of the rotating drum 601, and the automatic film coating is completed during the guiding process.

[0030] As Figures 1-6 shown, it also includes a spraying mechanism 7. The spraying mechanism 7 includes a rectangular opening 701, a spraying pipe 703, a second drive motor 702, a diversion pipe 704 and a diversion pump 705. The rectangular opening 701 is arranged on the box body 5, and a spraying pipe 703 is arranged inside the rectangular opening 701. Both ends of the spraying pipe 703 are connected to the second drive motor 702 through connectors to form a reciprocating swing mechanism. The spraying pipe 703 is connected to the film coating chamber through a diversion pipe 704 and a diversion pump 705; there are several spraying holes at the bottom of the spraying pipe 703.

[0031] It should be noted that, in order to improve the integrity of the coating on the steel structure fastening parts, we also designed a spraying mechanism 7. The coating solution inside the coating chamber is exported through a diversion pump 705, and then enters the spray pipe 703 through a diversion pipe 704. For the convenience of use, our diversion pipe 704 can be made of a flexible pipe, so as to achieve automatic spraying.

[0032] It should be further noted that, in order to increase the spraying range, we connect the spray pipe 703 to the fixed ear on the rectangular opening 701 through a connector, and then drive it through a second driving motor 702, so as to achieve left and right swinging under the action of the second driving motor 702.

[0033] As Figure 1 , Figure 5 and Figure 6 shown, a protective cover 4 is arranged on the outer wall of the gear 11; the filter tank 9 is a rectangular cavity structure with an upper opening, and a number of sieve holes are arranged at the bottom of the filter tank 9, and a collection tank 12 is arranged below the filter tank 9; a feed hopper 10 is arranged on the outer wall of the box body 5, and the feed hopper 10 is communicated with the coating chamber.

[0034] It should be noted that we set a filter tank 9 on the upper part of the fixing frame 1 to receive the steel structure fastening parts exported by the rotating drum 601. By allowing it to stand for a period of time, the coating remaining on the surface is collected into the collection tank 12 at the bottom, so as to achieve recycling.

[0035] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present utility model.
