Description

Technical Field

[0001] This invention relates to the field of steel structure processing equipment technology, and in particular to a high-efficiency spraying device for steel structure processing. Background Technology

[0002] Section steel is a type of strip steel with a specific cross-sectional shape and size, and is one of the four major categories of steel (plates, pipes, sections, and wires). Based on cross-sectional shape, section steel is divided into simple section steel and complex section steel (irregular-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beams, channel steel, rails, window frame steel, bent section steel, etc. Steel structures are structures composed of steel materials and are one of the main types of building structures. The structure mainly consists of beams, steel columns, steel trusses, and other components made of section steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Due to its light weight and ease of construction, it is widely used in large factories, stadiums, and high-rise buildings.

[0003] Patent CN112354762A discloses a steel structure spraying device. The key technical features of the device are: it includes a base and a spraying device. At least two sets of roller assemblies for sliding support of steel profiles are provided on the upper end of the base. The roller assemblies include a longitudinal limiting mechanism and a transverse limiting mechanism. The longitudinal limiting mechanism includes a bottom roller and a top roller. The bottom roller and the top roller are arranged opposite to each other. Multiple bottom rollers are arranged in parallel. The bottom roller assembly is fixed to the base by a mounting plate. This device can accommodate the clamping and transport of steel sections of different specifications by adjusting the distance between the longitudinal and transverse limiting mechanisms and themselves. During transport, a spraying device is used to spray the surface of the steel structure. The height of the spray gun can be adjusted to meet the spraying requirements. In addition, floating objects in the air during the spraying process can be collected by the spray floating object suction platform, optimizing the surrounding environment. However, this device has some drawbacks. First, when spraying steel structures, the device can only spray one side of the steel structure, and cannot achieve all-round spraying. Second, the device cannot spray the limited parts of the steel structure at the end of the transport and spraying process, thus preventing the entire product from being sprayed at once. Third, after the steel structure is sprayed, the paint surface requires a certain amount of time to dry, which prevents the finished product from being quickly unloaded, reducing production efficiency.

[0014] Furthermore, both the second drive device and the spraying device are mounted on the drive end of the lead screw slide.

[0015] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] Firstly, existing devices can only paint one side of a steel structure, failing to achieve omnidirectional painting. This new device, however, first places the end of the product to be painted onto the first mating device. Then, a conveyor motor drives a rotating disc towards the painting equipment, simultaneously moving a mechanical clamp on the disc. This clamps the other end of the product, thus loading and clamping it. This allows the device to fix the product according to its dimensions for painting, and is suitable for various applications. For different products, the conveyor motor continues to drive the product toward the spraying equipment. The first cooperating device 7 moves in coordination with the product. When one end of the product is directly below the spraying equipment, the spraying equipment is started to spray the product. During the spraying process, the drive motor drives the rotating disk to rotate, and the second cooperating device 8 operates synchronously, thereby driving the product on the mechanical fixture to rotate 360 ​​degrees, realizing 360-degree spraying of the product. By continuously conveying and rotating the product, after the entire product is sprayed, the product can be unloaded by the operation of the second drive device.

[0017] Secondly, in the existing technology, the device cannot complete the painting of the entire product in one go because it cannot paint the restricted parts of the steel structure when it is being transported and painted. In this device, after one end of the product is painted, the second drive device drives the mechanical clamp on the second drive device to clamp and fix the painted and dried end of the product. This allows the mechanical clamp on the first drive device to release the other end of the product, and then the entire product can be painted. After the entire product is painted, the second drive device can move the product to a position where it can be removed.

[0018] Thirdly, in the existing technology, after the steel structure is sprayed, the paint surface needs a certain amount of time to dry, which makes it impossible to quickly unload the sprayed product, thus reducing production efficiency. This device uses the operation of the conveyor motor to drive the product to continue moving forward, and one end of the sprayed product will be located at the air outlet of the fan. At this time, by starting the fan, the freshly sprayed product can be dried quickly, which can facilitate the subsequent rapid unloading operation and improve production efficiency.

[0019] Fourth, when spraying products of different sizes, the distance between the spraying equipment and the first drive device needs to be adjusted according to the size of the product. At this time, the distance between the spraying equipment and the first drive device can be adjusted by starting the screw slide to drive the spraying device and the second drive device to move. This allows for effective and rapid spraying of the product, enabling spraying of products of different sizes and ensuring product quality.

[0020] Fifth, when the product is being loaded, the cooperating rollers provide support, facilitating the fixing of the product by mechanical clamps. When the product is being conveyed, the cooperating rollers provide both conveying and support. When the product is being unloaded, the cooperating rollers on the second cooperating device provide both conveying and support during unloading. When the product rotates, the operation of the direction-changing motor drives the cooperating rollers on the second and third changing gears to rotate synchronously by 90 degrees, so that the cooperating rollers and cooperating springs move in coordination during product rotation, thereby providing a stable support effect.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0036] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] This invention provides a high-efficiency spraying device for steel structure processing, including a lead screw slide 11, a worktable 1, a first drive device 2, a second drive device 3, a spraying device 5, a direction conversion device 6, a first mating device 7, and a second mating device 8. The lead screw slide 11 is mounted on the worktable 1, the first drive device 2 is mounted on the worktable 1, and the second drive device 3 is mounted on the lead screw slide 11. The first drive device 2 and the second drive device 3 have identical structures. The spraying device 5 is mounted on the lead screw slide 11, the direction conversion device 6 is mounted on the spraying device 5, and the first mating device 7 and the second mating device 8 have identical structures. The first mating device 7 is located near... The first driving device 2 is mounted on a direction conversion device 6 on one side, and the second cooperating device 8 is mounted on the direction conversion device 6 near the second driving device 3. The first cooperating device 7 and the second cooperating device 8 are symmetrically arranged. The first driving device 2 includes a driving assembly 21, a rotating assembly 22, and a conveying assembly 23. The driving assembly 21 is mounted on the worktable 1, the rotating assembly 22 is mounted on the driving assembly 21, and the conveying assembly 23 is mounted on the rotating assembly 22. This device can perform 360-degree spraying operations on products through the first driving device 2 and the second driving device 3, and is suitable for products of different sizes. At the same time, it can quickly unload the sprayed products, improving production efficiency.

[0038] Working principle: When spraying a product, the distance between the spraying equipment 53 and the first drive device 2 needs to be adjusted according to the required product size. This is done by starting the lead screw slide 11 to move the spraying equipment 5 and the second drive device 3, thus adjusting the distance between them. After size adjustment, the end of the product to be sprayed is placed on the first mating device 7. The conveyor motor 232 drives the rotating disk 222 towards the spraying equipment 53, simultaneously moving the mechanical clamp 4 on the rotating disk 222, causing the other end of the product to be clamped by the mechanical clamp 4. The product is clamped and loaded, and then the conveyor motor 232 continues to drive the product toward the spraying equipment 53. The first coordinating device 7 moves in coordination with the product. When one end of the product is directly below the spraying equipment 53, the spraying equipment 53 is started to spray the product. During the spraying process, the drive motor 212 drives the rotating disk 222 to rotate, and the second coordinating device 8 operates synchronously, thereby driving the product on the mechanical clamp 4 to rotate 360 ​​degrees. After one end of the product is sprayed, the conveyor motor 232 drives the product to continue moving forward, and the spraying... One end of the coated product will be located at the air outlet of the blower 9. At this point, the blower 9 is activated to dry the freshly coated product, quickly facilitating subsequent unloading. Simultaneously, the second drive device 3 operates, driving the mechanical clamp 4 located on it to clamp and fix one end of the dried product. This allows the mechanical clamp 4 on the first drive device 2 to release the other end of the product, enabling the entire product to be coated. After the entire product is coated, the second drive device 3 moves the product to a position where it can be removed. During loading, the cooperating roller 74 provides support, facilitating the product's fixation by the mechanical clamp 4. During product conveying, the cooperating roller 74 provides both conveying and support. During product unloading, the cooperating roller 74 on the second cooperating device 8 provides both conveying and unloading support. When the product rotates, the operation of the direction conversion motor 61 drives the cooperating roller 74 on the second conversion gear 63 and the third conversion gear 64 to rotate synchronously by ninety degrees, causing the cooperating roller 74 and the cooperating spring 72 to move in coordination during product rotation, thereby providing a stable support effect.

[0039] Preferably, the drive assembly 21 includes a drive base 211, a drive motor 212, a first pulley 213, a second pulley 214, a transmission belt 215, and a fixed frame 216. The drive base 211 is mounted on the workbench 1, the drive motor 212 is mounted on the drive base 211, the first pulley 213 is mounted on the output end of the drive motor 212, the fixed frame 216 is mounted on the side end of the drive base 211, the second pulley 214 is sleeved on the fixed frame 216 and rotatably connected to the fixed frame 216, and the transmission belt 215 is sleeved on the first pulley 213 and the second pulley 214. When the rotating assembly 22 needs to run, the drive motor 212 drives the first pulley 213 on the output end of the drive motor 212 to rotate. The rotation of the first pulley 213 drives the second pulley 214 to rotate on the fixed frame 216 through the transmission belt 215, thereby driving the rotating assembly 22 to rotate, which facilitates subsequent product rotation spraying operations.

[0040] Preferably, the rotating assembly 22 includes a rotating telescopic rod 221 and a rotating disk 222. There are two rotating telescopic rods 221, which are symmetrically arranged on the second pulley 214. The rotating disk 222 is located at the ends of the two rotating telescopic rods 221. When the product is sprayed in a 360-degree manner, the second pulley 214 is driven to rotate on the fixed frame 216 by the operation of the drive motor 212. The rotation of the second pulley 214 drives the two rotating telescopic rods 221 to rotate, and the rotation of the two rotating telescopic rods 221 drives the rotating disk 222 to rotate, thereby realizing the 360-degree rotating spraying operation of the product.

[0041] Preferably, the conveying assembly 23 includes a conveying seat 231, a conveying motor 232, a first helical gear 233, a second helical gear 234, a conveying block 235, a conveying channel 236, a conveying screw 237, and a conveying sleeve 238. The fixed frame 216 has a conveying groove. The conveying seat 231 is located on the side of the fixed frame 216. The conveying motor 232 is mounted on the conveying seat 231. The first helical gear 233 is located on the output end of the conveying motor 232. The conveying channel 236 is located within the conveying groove and extends out of the groove at one end.

The second helical gear 234 is located at one end of the conveying screw 237 and meshes with the first helical gear 233. The conveying sleeve 238 is sleeved on the conveying screw 237 and is threadedly connected. One end of the conveying sleeve 238 passes through the conveying screw 237. The conveying channel 236 is internally connected to the rotating disk 222 and is rotatably connected to the rotating disk 222. The conveying sleeve 238 is slidably fitted to the conveying channel 236. When conveying products, the conveying motor 232 drives the lower end of the first helical gear 233 on the output end of the conveying motor 232. The rotation of the first helical gear 233 drives the second helical gear 234 to rotate. The rotation of the second helical gear 234 drives the conveying screw 237 to rotate on the conveying block 235. The conveying sleeve 238 is threadedly connected to the conveying screw 237 and is limited by the conveying sleeve 238, thereby driving the conveying sleeve 238 to move on the conveying screw 237. The movement of the conveying sleeve 238 drives the rotating disk 222 to move, thereby driving the product on the rotating disk 222 to move towards the spraying device 5. The two rotating telescopic rods 221 cooperate to extend and retract, thereby realizing the conveying of the product to the spraying device 5, where the spraying device 5 performs the spraying operation on the product.

[0042] Preferably, it also includes a mechanical clamp 4. The rotating disk 222 is provided with a fixing groove 223. There are two mechanical clamps 4. The two mechanical clamps 4 are respectively set in the fixing groove 223 on the rotating disk 222 of the first driving device 2 and the fixing groove 223 on the rotating disk 222 of the second driving device 3. The mechanical clamps 4 can play a good role in fixing the product during the product spraying operation.

[0043] Preferably, the spraying device 5 includes a spraying panel 51, a spraying frame 52, and a spraying equipment 53. The spraying panel 51 is mounted on the lead screw slide 11, the spraying frame 52 is mounted on the spraying panel 51, and the spraying equipment 53 is mounted on the spraying frame 52 with the spray nozzle facing downwards. When spraying a product, the end of the product to be sprayed is first placed on the first mating device 7. At this time, the conveyor motor 232 drives the rotating disk 222 to move towards the spraying equipment 53, simultaneously driving the mechanical clamp 4 on the rotating disk 222 to move, so that the other end of the product is clamped by the mechanical clamp 4, thereby realizing the loading and clamping of the product. This allows the device to spray products according to their required dimensions. The product is fixed and then sprayed. This process is applicable to different products. The conveyor motor 232 continues to drive the product toward the spraying equipment 53. The first cooperating device 7 moves in coordination with the product. When one end of the product is directly below the spraying equipment 53, the spraying equipment 53 is started to spray the product. During the product spraying process, the drive motor 212 drives the rotating disk 222 to rotate. The second cooperating device 8 operates synchronously, thereby driving the product on the mechanical clamp 4 to rotate 360 ​​degrees, realizing 360-degree spraying of the product. By continuously conveying and rotating the product, the entire product is sprayed. After the product is completed, the second drive device 3 unloads the product.

[0044] Preferably, the direction conversion device 6 includes a direction conversion motor 61, a first conversion gear 62, a second conversion gear 63, and a third conversion gear 64. The direction conversion motor 61 is mounted on the spraying panel 51. The first conversion gear 62 is mounted on the output end of the direction conversion motor 61. The second conversion gear 63 is mounted on the side end of the first conversion gear 62 and is rotatably connected to the spraying panel 51. The third conversion gear 64 is mounted on the other side of the first conversion gear 62 and is rotatably connected to the spraying panel 51. When the first mating device 7 and the second mating device 8 need to change angles, the direction conversion motor 61 drives the first conversion gear 62 on the output end of the direction conversion motor 61 to rotate. The rotation of the first conversion gear 62 drives the second conversion gear 63 and the third conversion gear 64 to rotate on the spraying panel 51, thereby driving the first mating device 7 and the second mating device 8 to rotate 90 degrees. By using gears to rotate in a coordinated manner, the first mating device 7 and the second mating device 8 can be rotated 90 degrees more accurately.

[0045] Preferably, the first mating device 7 is disposed on the second conversion gear 63, and the second mating device 8 is disposed on the third conversion gear 64. The first mating device 7 includes a mating block 71, a mating spring 72, a mating plate 73, and a mating roller 74. The mating block 71 is disposed on the second conversion gear 63. Two mating springs 72 are provided and symmetrically disposed on the mating block 71. The mating plate 73 is disposed on the two mating springs 72, and the mating roller 74 is disposed on the mating plate 73. When the product is being fed, the mating roller... Roller 74 provides support, facilitating the fixing of the product by the mechanical clamp 4. When the product is being conveyed, roller 74 provides both conveying and support. When the product is being unloaded, roller 74 on the second coordinating device 8 provides both conveying and unloading support. When the product rotates, the operation of the direction-changing motor 61 drives the roller 74 on the second and third changing gears 63 and 64 to rotate 90 degrees synchronously. This allows the roller 74 and spring 72 to move in coordination during product rotation, thus providing stable support.

[0046] Preferably, it also includes a fan 9, which is installed on the spraying panel 51 and located at the side of the spraying frame 52. After one end of the product is sprayed, the product continues to move forward by the operation of the conveyor motor 232. The sprayed end of the product will be located at the air outlet of the fan 9. At this time, the fan 9 is started to air dry the product that has just been sprayed, so that the sprayed product can be dried quickly for subsequent unloading operations. At the same time, the mechanical clamp 4 located on the second drive device 3 clamps and fixes one end of the sprayed and dried product, which allows the mechanical clamp 4 on the first drive device 2 at the other end of the product to release the product, and then the entire product is sprayed.

[0047] Preferably, the second drive device 3 and the spraying device 5 are both mounted on the drive end of the lead screw slide 11. Due to the different sizes of the products, when spraying products of different sizes, it is necessary to first adjust the distance between the spraying device 53 and the first drive device 2 according to the required product size. At this time, the distance between the spraying device 5 and the first drive device 2 can be adjusted by starting the lead screw slide 11 to drive the spraying device 5 and the second drive device 3 to move, thereby effectively and quickly spraying the product and ensuring the quality of the product.
