Description

Technical Field

[0001] This utility model relates to the field of corrugated steel web processing technology, and in particular to a spraying device for corrugated steel web. Background Technology

[0002] Corrugated steel web is a type of steel structural member with a wavy cross section. Due to its advantages such as high strength, light weight, and good seismic performance, it is widely used in engineering fields such as bridges, factories, and high-rise buildings. In order to improve the corrosion resistance and service life of corrugated steel web, its surface needs to be sprayed during the processing to form a protective coating.

[0003] In the existing technology, when painting steel web plates, the steel web plates are usually hoisted onto a conveyor belt and transported to the spray booth for painting. During the entire painting process, multiple nozzles set in the spray booth spray simultaneously. However, during transportation, due to friction, placement position and other reasons, the steel web plates may deviate from their designated position, resulting in uneven painting.

[0004] The existing patent (publication number: CN219503024U) provides a corrugated steel web spraying device, including a spraying chamber, multiple spraying components, and a conveyor belt. It further includes: a roller assembly passing through the spraying chamber and spaced apart from the conveyor belt on both sides of the spraying chamber; the roller assembly includes multiple roller fixing columns, multiple intermediate rollers rotatably connected to the roller fixing columns at both ends, and two end rollers disposed on the roller fixing columns; the multiple intermediate rollers are arranged between the two end rollers, and the intermediate rollers and end rollers are located on the same plane to receive one end of the corrugated steel web; a chain plate surrounding the conveyor belt surface, with one end of the corrugated steel web abutting against the chain plate; and a limiting member surrounding both the intermediate rollers and end rollers, with the other end of the corrugated steel web abutting against the limiting member. This utility model effectively improves the problem in the prior art where the steel web may deviate during transportation, leading to uneven painting.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the nozzles of existing corrugated steel web coating devices are typically fixed and cannot adaptively adjust to the angle of the nozzles based on the crests and troughs of the corrugated steel web. This results in over-coating and sagging at the crests and under-coating or missed areas at the troughs, leading to poor coating uniformity and consequently affecting the protective effect on the surface of the corrugated steel web.

[0006] To address this, a spraying device for corrugated steel web plates is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a spraying device for corrugated steel web plates, which can solve the problem that the nozzles of existing corrugated steel web plate spraying devices are usually fixed and cannot adaptively adjust the angle of the nozzles according to the crests and troughs of the corrugated steel web plate. As a result, during the spraying process, the crests are prone to overspraying and sagging, while the troughs are prone to underspraying or missed spraying, resulting in poor spraying uniformity and affecting the protective effect of the corrugated steel web plate surface.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A spraying device for corrugated steel web plates includes a frame 1, an electric conveyor belt 2 is provided on the inner side of the frame 1, and a spraying mechanism 3 and a limiting mechanism 4 are provided on the top of the frame 1.

[0029] The spraying mechanism 3 includes a support frame 31, which is fixedly connected to the frame 1 on the side closest to the frame 1. An electric lifting rod 32 is fixedly connected to the top of the support frame 31. The output rod of the electric lifting rod 32 passes through the inside of the support frame 31 and is fixedly connected to a fixed frame 33. A servo motor 34 is fixedly connected to the right side of the fixed frame 33. A spraying pipe 35 is provided inside the fixed frame 33. The right side of the spraying pipe 35 passes through the right side of the fixed frame 33 and is fixedly connected to the output shaft of the servo motor 34. The left side of the spraying pipe 35 passes through the left side of the fixed frame 33 and is connected to an external paint pipe 36 through a rotary joint. The two sides of the surface of the spraying pipe 35 are rotatably connected to the inner wall of the fixed frame 33 through bearings. Multiple nozzles 37 are connected to the bottom of the spraying pipe 35. A PLC controller 38 is fixedly connected to the right side of the support frame 31.

[0030] In this embodiment: by setting up a frame 1, an electric conveyor belt 2, a spraying mechanism 3, and a limiting mechanism 4, during use, the frame 1 provides a supporting foundation for the electric conveyor belt 2, the spraying mechanism 3, and the limiting mechanism 4. The electric conveyor belt 2 can transport the corrugated steel web to be sprayed. The spraying mechanism 3 can automatically and flexibly adjust the spraying angle and spraying distance according to the crest and trough surface characteristics of the corrugated steel web, thereby effectively improving the uniformity of the coating thickness on the surface of the corrugated steel web and thus enhancing the protective effect on the surface of the corrugated steel web. The limiting mechanism 4 can precisely limit and constrain the position of the corrugated steel web during the transport process, avoiding the deviation of the corrugated steel web caused by factors such as workpiece placement deviation, ensuring that the corrugated steel web is always within the effective working range of the spraying mechanism 3, so that the coating can accurately cover the surface of the corrugated steel web.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the limiting mechanism 4 includes a fixed shell 41, which is located in front of the support frame 31. An adjusting motor 42 is fixedly connected to the right side of the fixed shell 41. A bidirectional screw 43 is fixedly connected to the output shaft of the adjusting motor 42. The left side of the bidirectional screw 43 extends through to the left side of the fixed shell 41. The side of the surface of the bidirectional screw 43 that is close to the inner wall of the fixed shell 41 is rotatably connected to the inner wall of the fixed shell 41 through a bearing.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, both sides of the surface of the bidirectional screw 43 are connected to internal thread blocks 44 by threads. The two internal thread blocks 44 are slidably connected to the inner wall of the fixed shell 41 on one side of the fixed shell 41. The bottom of the two internal thread blocks 44 is fixedly connected to the connecting plate 45. The bottom of the two connecting plates 45 is fixedly connected to the limiting plate 46. The two limiting plates 46 are located on both sides of the front side of the top of the electric conveyor belt 2.

[0033] Specifically, such as Figure 1 , Figure 4 As shown, support plates 47 are fixedly connected to both sides of the bottom of the fixed shell 41, and the bottom of the two support plates 47 are fixedly connected to the two sides of the front top of the frame 1 respectively.

[0034] In this embodiment: by setting a fixed shell 41, adjusting motor 42, bidirectional screw 43, internal threaded block 44, connecting plate 45, limiting plate 46 and support plate 47, in use, the distance between the two limiting plates 46 is adjusted according to the width specification of the corrugated steel web to be processed. By starting the adjusting motor 42, its output shaft drives the bidirectional screw 43 to rotate in the fixed shell 41 through the bearing. At this time, the two internal threaded blocks 44 connected by threads on both sides of the surface of the bidirectional screw 43 will slide synchronously towards or away from each other along the inner wall of the fixed shell 41 under the action of the threads. The two internal threaded blocks 44 will drive the two limiting plates 46 to move synchronously towards or away from each other through the two connecting plates 45 at the bottom, until the two limiting plates 46 are adjusted to the distance matching the width of the corrugated steel web, so as to achieve precise positioning of the corrugated steel web during the conveying process and avoid its deviation due to placement deviation and other factors. The fixed shell 41 can be supported and fixed by setting the support plate 47.

[0035] Specifically, such as Figure 5 As shown, the top of the support frame 31 has a through hole 5 that works with the electric lifting rod 32, and the output rod surface of the electric lifting rod 32 is slidably connected to the inner wall of the through hole 5.

[0036] Specifically, such as Figure 1 , Figure 3 , Figure 5 As shown, limiting rods 6 are fixedly connected to both sides of the top of the fixed frame 33. The top of the limiting rods 6 extends through to the top of the support frame 31. Sliding holes 7 that cooperate with the limiting rods 6 are provided on both sides of the top of the inner side of the support frame 31. The surface of the limiting rods 6 is slidably connected to the inner wall of the sliding holes 7.

[0037] In this embodiment: by providing through hole 5, the output rod of electric lifting rod 32 can pass through support frame 31 for telescopic output; by providing limiting rod 6, the fixed frame 33 can be guided and limited, so that the fixed frame 33 can move up and down smoothly for adjustment; by providing sliding hole 7, the limiting rod 6 can pass through support frame 31 for up and down sliding.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, an oven 8 is provided on the rear side of the support frame 31. The two sides of the bottom of the oven 8 are fixedly connected to the two sides of the top of the frame 1. A drying device 9 is fixedly connected to the top of the inner wall of the oven 8.

[0039] Specifically, such as Figure 1 As shown, support legs 10 are fixedly connected to both sides of the bottom of the frame 1, and there are several support legs 10.

[0040] In this embodiment: by setting up an oven 8 and a drying device 9, the coating on the surface of the corrugated steel web plate can be dried in an auxiliary manner after spraying. By setting up support legs 10, the frame 1 can be stably supported.

[0041] Working principle: In use, firstly, the distance between the two limiting plates 46 is adjusted according to the width specification of the corrugated steel web to be processed. This can be achieved by starting the adjusting motor 42, which drives the bidirectional screw 43 to rotate within the fixed housing 41 via bearings. At this time, the two internally threaded blocks 44 connected by threads on both sides of the surface of the bidirectional screw 43 will slide synchronously towards or away from each other along the inner wall of the fixed housing 41 under the action of the threads. The two internally threaded blocks 44 will then drive the two limiting plates 46 to move synchronously towards or away from each other via the two connecting plates 45 at the bottom, until the distance between the two limiting plates 46 is adjusted to match the width of the corrugated steel web. It can achieve precise positioning during the conveying of corrugated steel web plates, preventing them from shifting due to placement deviations or other factors. The corrugated steel web plates to be sprayed are then smoothly placed on the electric conveyor belt 2 inside the frame 1, positioned between two limit plates 46. The controller then starts the electric conveyor belt 2, causing it to move the corrugated steel web plates towards the spraying area at a preset speed. When the corrugated steel web plates are about to enter the working range of the spraying mechanism 3, the spraying parameters are set via the PLC controller 38. Simultaneously, the left side of the spraying pipe 35 is stably connected to the external paint pipe 36 via a rotary joint. Then, the PLC controller 38 controls the electric lifting rod 32 to start, allowing... The output rod of the electric lifting rod 32 drives the fixed frame 33 to rise and fall synchronously. The limit rods 6 on both sides of the top of the fixed frame 33 slide synchronously along the sliding holes 7 on the top of the inner side of the support frame 31 to ensure that the lifting and falling process of the fixed frame 33 is smooth until the nozzle 37 at the bottom of the spray pipe 35 maintains the optimal spraying distance with the surface of the corrugated steel web. After the corrugated steel web enters the spraying area, the external paint pipe 36 delivers paint into the spray pipe 35. The paint is distributed to multiple nozzles 37 through the spray pipe 35 and atomized and sprayed out, evenly covering the surface of the corrugated steel web. During this process, the electric conveyor belt 2 continuously conveys the corrugated steel web, and the servo motor 34 can adjust the movement of the corrugated steel web according to the wave pattern. During the cycle, the rotation angle of the spraying pipe 35 is finely adjusted in real time under the control of the PLC controller 38 to ensure that the nozzle 37 always maintains an appropriate angle with the curved surface of the web. At the same time, the electric lifting rod 32 can finely adjust the height of the nozzle 37 as needed, thereby effectively improving the uniformity of the coating thickness on the surface of the corrugated steel web. The corrugated steel web after spraying is continued to be transported by the electric conveyor belt 2 to the oven 8 behind the support frame 31. At the same time, the drying equipment 9 on the top of the inner wall of the oven 8 is started to quickly dry and cure the coating on the surface of the corrugated steel web. Finally, the dried corrugated steel web is transported out of the oven 8 by the electric conveyor belt 2, thus completing the entire spraying process.

[0042] The above are merely preferred embodiments of the present utility model and are 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.
