Description

Technical Field

[0001] This utility model belongs to the field of ferrous metal spray painting technology, and in particular relates to a surface spray painting device for ferrous metal smelting and rolling products. Background Technology

[0002] A surface painting device for ferrous metal smelting and rolling is an automated equipment specifically designed for surface coating of ferrous metals such as iron and steel after rolling, forging, and forming processes such as sheet metal, pipes, and profiles. Through the coordinated operation of systems including atomized spraying, paint supply circulation, workpiece conveying and positioning, and exhaust paint mist treatment, it achieves uniform, efficient, and controllable surface painting. It also features paint recovery and safety protection functions to meet quality requirements such as corrosion resistance, decoration, and weather resistance. When recovering paint, surface painting devices for ferrous metal smelting and rolling often require filtration. However, existing surface painting devices for ferrous metal smelting and rolling mostly require multiple bolts for filter installation. This installation method necessitates users to disassemble the filters one by one using wrenches and other tools, which is time-consuming, labor-intensive, and severely impacts production efficiency. Therefore, a surface painting device for ferrous metal smelting and rolling is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a surface painting device for ferrous metal smelting and rolling products. By incorporating a disassembly assembly, specifically by grasping the filter screen and pushing it inwards, two locking blocks on either side press against a second locking block via an inclined surface. This causes a sliding rod to separate the limiting plate and compress a spring. Once the first locking block passes the second locking block, the spring returns to its original position, locking the second locking block and completing the filter screen fixation. This significantly improves maintenance efficiency, ensures filtration accuracy, and reduces the risk of product quality defects. It also solves the problem that existing surface painting devices for ferrous metal smelting and rolling products often require multiple bolts for filter screen installation. This installation method necessitates the user to use wrenches and other tools to disassemble the filter screens one by one, which is time-consuming, labor-intensive, and severely impacts production efficiency.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a surface painting device for ferrous metal smelting and rolling products, comprising a housing with an observation door on the front and a glass window on the front of the observation door. A handle is installed on the right side of the observation door. The ferrous metal products are placed inside the housing, and two filters are installed inside the housing. The device also includes: a recycling mechanism located at the bottom of the housing for recycling paint; and a clamping mechanism located inside the housing for clamping and fixing the ferrous metal products. During the painting process, workers can observe the ferrous metal products inside through the observation window.

[0006] Furthermore, the recycling mechanism includes a disassembly assembly located at the bottom of the housing. The disassembly assembly is used for quick disassembly of the top filter screen. The disassembly assembly includes two locking blocks, which are respectively installed on the left and right sides of the bottom filter screen. Sliding rods are slidably connected to the left and right sides of the housing. Springs are wound around the outer surfaces of the two sliding rods. The springs can automatically drive the locking blocks to fit tightly against the wedge-shaped surfaces of the locking blocks through elastic reset, eliminating the need for manual tightening of bolts and preventing the filter screen from loosening due to improper manual operation.

[0007] Furthermore, the recycling mechanism includes a painting assembly disposed on the top of the housing, the painting assembly being used to paint ferrous metal smelting products.

[0008] Furthermore, a knob is installed on the side of each of the two sliding rods that are far apart from each other, and a locking block is installed on the side of each of the two sliding rods that are close to each other. A limiting plate is installed on the outer surface of each of the two sliding rods. Both locking blocks are wedge-shaped, and both locking blocks are wedge-shaped. The inclined surfaces of both locking blocks are engaged with the inclined surfaces of both locking blocks. The limiting plate ensures that the spring is always compressed and reset along the axial direction of the sliding rod, avoiding jamming caused by lateral displacement of the spring and ensuring the success rate of locking the disassembly assembly. At the same time, the limiting plate limits the maximum sliding stroke of the sliding rod, preventing the locking block from disengaging from the box track due to excessive manual pulling of the sliding rod.

[0009] Furthermore, the painting assembly includes two C-shaped water pipes, both of which are installed on the left and right sides of the housing. A water storage tank is installed at the bottom of the housing, and an arc-shaped plate is installed inside the water storage tank. A guide block is installed at each of the four corners of the arc-shaped plate. The arc-shaped plate is arc-shaped, and the side of each of the four guide blocks closest to the center of the arc-shaped plate is sloped. The arc-shaped design that fits the side wall of the housing can evenly distribute the water flow on both sides of the inside of the housing, forming a water curtain barrier that effectively intercepts the paint mist splashed during the painting process and prevents the paint mist from adhering to the inner wall of the housing and being difficult to clean.

[0010] Furthermore, a water pump is installed on the back of the housing, and a water pipe is installed on the top of the water pump. The top of the water pipe is connected to the housing. A nozzle is installed inside the housing, and the water pipe is connected to the top of the nozzle. A water inlet is installed on the right side of the water storage tank. The nozzle adopts a high-pressure atomizing nozzle design, which can break the paint into fine droplets of 5-10μm, so that the paint can be evenly covered on the surface of the ferrous metal smelting product.

[0011] Furthermore, the clamping mechanism includes a motor, which is mounted on the right side of the housing. The output end of the motor is fixedly connected to a threaded rod via a coupling. Two internal threaded blocks are threadedly connected to the outer surface of the threaded rod. Guide rails are slidably connected to the top of the two internal threaded blocks. The top of each guide rail is fixedly connected to the inner wall of the housing. The threads on the outer surface of the threaded rod are arranged in opposite directions. Anti-corrosion spray can be sprayed on the surface of the threaded rod. In addition, the staff can perform regular maintenance on the threaded rod.

[0012] Furthermore, each of the two internally threaded blocks has an L-shaped frame 1 installed at its bottom. An L-shaped frame 2 is rotatably connected to the side of each L-shaped frame 1 that is close to each other. A knob 2 is located on the right side of the L-shaped frame 2 on the right side. Locking bolts are threaded onto the side of each L-shaped frame 1 that is far from each other. Two guide rails 1 are located on the side of each L-shaped frame 1 that is close to each other. The top right side of the L-shaped frame 1 on the left side is fixedly connected to the guide rail 1, and the bottom left side of the L-shaped frame 1 on the right side is fixedly connected to the guide rail 1. Two guide rails are provided on one side of the L-shaped frame two that are close to each other. The top right side of the L-shaped frame two on the left is fixedly connected to the guide rail two, and the bottom left side of the L-shaped frame two on the right is fixedly connected to the guide rail two. The two guide rails one and the two guide rails two are arranged in a cross arrangement. The locking bolts are high-strength internal hex bolts (made of No. 45 steel, galvanized), which can provide sufficient locking force. After the L-shaped frame two clamps the ferrous metal product, the relative position of the L-shaped frame two and the L-shaped frame one can be fixed by tightening the locking bolts.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting up a disassembly component, specifically involves holding the filter screen and pushing it inward. The first locking block on both sides presses the second locking block through the inclined surface, causing the sliding rod to drive the limiting plate to separate and compress the spring. After the first locking block passes the second locking block, the spring resets and drives the second locking block to lock, thus completing the filter screen fixation. This greatly improves maintenance efficiency, ensures filtration accuracy, and reduces the risk of product quality defects.

[0015] 2. This utility model, by setting up a clamping mechanism, specifically involves starting a motor to drive the reverse-threaded rod to rotate, causing two internal threaded blocks to approach along the guide rail, which in turn drives L-shaped frame one and L-shaped frame two to approach simultaneously. The guide rail one and guide rail two on both sides are inserted into the corresponding sliding grooves to complete the clamping of the ferrous metal smelting product. The two inner L-shaped frames two are fixed with locking bolts. When flipping is required, the locking bolts are removed, and the knob two is held to drive the L-shaped frames two to flip the ferrous metal smelting product. By flipping, the ferrous metal smelting product can be painted more efficiently, and the cleaning efficiency is also higher.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] 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 scope of protection of the present utility model.

[0029] Please see Figures 1-8As shown, this utility model is a surface painting device for ferrous metal smelting and rolling products, including a box body 1, an observation door 111 installed on the front of the box body 1, a glass window 112 installed on the front of the observation door 111, a handle 113 installed on the right side of the observation door 111, ferrous metal smelting products 114 disposed inside the box body 1, and two filters 115 disposed inside the box body 1, and also includes a recycling mechanism 2, which is disposed at the bottom of the box body 1 and is used to recycle the paint, and a clamping mechanism 3, which is disposed inside the box body 1 and is used to clamp and fix the ferrous metal smelting products 114. The recycling mechanism 2 includes a disassembly component 21. Located at the bottom of housing 1, the disassembly assembly 21 is used for quick disassembly of the top filter screen 115. The disassembly assembly 21 includes two locking blocks 211, which are respectively installed on the left and right sides of the bottom filter screen 115. Sliding rods 212 are slidably connected to both the left and right sides of housing 1. Springs 213 are wound around the outer surfaces of both sliding rods 212. The recycling mechanism 2 includes a painting assembly 22, located at the top of housing 1. The painting assembly 22 is used for painting the ferrous metal smelting product 114. A knob 214 is installed on the side of the two sliding rods 212 that is far apart from each other, and a locking block 215 is installed on the side of the two sliding rods 212 that is close to each other. Limiting plates 216 are installed on the outer surface of the slide bar 212. Two locking blocks 1 211 and two locking blocks 215 are wedge-shaped. The inclined surfaces of the two locking blocks 1 211 and the two locking blocks 215 are engaging surfaces. The painting assembly 22 includes two C-shaped water pipes 221, which are installed on the left and right sides of the housing 1. A water storage tank 228 is installed at the bottom of the housing 1. An arc-shaped plate 222 is installed inside the water storage tank 228. A guide block 223 is installed at each of the four corners of the arc-shaped plate 222. The arc-shaped plate 222 is arc-shaped, and the side of each guide block 223 closest to the center of the arc-shaped plate 222 is inclined. A water pump 224 is installed on the back of the housing 1. A water pipe 225 is installed on the top of the water pump 224, and the top of the water pipe 225 is connected to the housing 1. A nozzle 226 is installed inside the housing 1, and the top of the water pipe 225 is connected to the nozzle 226. A water inlet 227 is installed on the right side of the water storage tank 228. Specifically, when the filter screen 115 is held and pushed inward, the first locking block 211 on both sides squeezes the second locking block 215 through the inclined surface, causing the slide rod 212 to drive the limiting plate 216 to separate and compress the spring 213. When the first locking block 211 passes the second locking block 215, the spring 213 returns to its original position and drives the second locking block 215 to lock, thus fixing the filter screen 115. This greatly improves maintenance efficiency, ensures the filtration accuracy, and reduces the risk of product quality defects.

[0030] The clamping mechanism 3 includes a motor 311, which is mounted on the right side of the housing 1. The output end of the motor 311 is fixedly connected to a threaded rod 312 via a coupling. Two internal threaded blocks 314 are threadedly connected to the outer surface of the threaded rod 312. Guide rails 313 are slidably connected to the tops of the two internal threaded blocks 314, and the tops of the guide rails 313 are fixedly connected to the inner wall of the housing 1. The threads on the outer surface of the threaded rod 312 are arranged in opposite directions. An L-shaped frame 315 is mounted at the bottom of each of the two internal threaded blocks 314. Both L-shaped frames 315 are rotatably connected to each other on their adjacent sides. A knob 317 is located on the right side of the L-shaped frame 318. Locking bolts 319 are threaded onto the opposite sides of the two L-shaped frames 315. Two guide rails 320 are located on the adjacent sides of the two L-shaped frames 315. The top right side of the left L-shaped frame 315 is fixedly connected to guide rail 320, and the bottom left side of the right L-shaped frame 315 is fixedly connected to guide rail 320. Two guide rails 321 are provided on one side of the L-shaped frame 318 that are close to each other. The top right side of the L-shaped frame 318 on the left is fixedly connected to the guide rail 321, and the bottom left side of the L-shaped frame 318 on the right is fixedly connected to the guide rail 321. The two guide rails 320 are arranged in a cross configuration, and the two guide rails 321 are also arranged in a cross configuration. Specifically, the starting motor 311 drives the threaded rod 312 with a reverse thread to rotate, and the two internal thread blocks 314 move closer along the guide rail 313, thereby driving the L-shaped frame 318 to rotate. 5. The L-shaped frame 2 318 approaches simultaneously, and the guide rails 1 320 and 2 321 on both sides are inserted into the corresponding slots to clamp the ferrous metal product 114. The two inner L-shaped frames 2 318 are fixed with locking bolts 319. When flipping, the locking bolts 319 are removed, and the knob 2 317 is held to drive the L-shaped frame 2 318 to flip the ferrous metal product 114. By flipping, the ferrous metal product 114 can be painted more efficiently, and the cleaning efficiency is also higher.

[0031] A specific application of this embodiment is as follows: In use, the user can first open the observation door 111 by holding the handle 113, and then place the ferrous metal smelting product 114 inside the two L-shaped frames 318. Then, the motor 311 is started to drive the threaded rod 312 to rotate. Since the threads on the threaded rod 312 are reversed, and the two internal thread blocks 314 are respectively set on the reversed threads, and the top guide rail 313 slides and limits the movement of the two internal thread blocks 314, when the threaded rod 312 rotates, it will drive the two internal thread blocks 314 to move closer together, and also drive the two L-shaped frames 315 to move closer together. At this time, the two L-shaped frames 318 will also move closer together along with the two L-shaped frames 315. As the pattern blocks 314 continue to move closer together, the guide rail 320 at the top of the left L-shaped frame 315 will insert into the groove of the right L-shaped frame 315, and the guide rail 320 at the bottom of the right L-shaped frame 315 will insert into the groove at the bottom of the left L-shaped frame 315. Then, the guide rail 321 at the top of the left L-shaped frame 318 will insert into the groove at the top of the right L-shaped frame 318, and the guide rail 321 at the bottom of the right L-shaped frame 318 will insert into the groove at the bottom of the left L-shaped frame 318. This clamps and secures the ferrous metal product 114. Once secured, this clamping method does not obstruct the front and back of the ferrous metal product 114, allowing for more comprehensive painting. In this process, the user can fix the two inner L-shaped frames 318 using locking bolts 319. Then, the user can inject paint into the water tank 228 through the water inlet 227. The water pump 224 can then be activated to fill the water tank 228 with paint through the water pipe 225, which then flows into the spray nozzle 226 to paint the fixed ferrous metal product 114. When the front is finished being painted, the locking bolts 319 can be turned to release the L-shaped frames 318, and the knob 317 can be held to rotate the L-shaped frames 318, flipping the ferrous metal product 114 to paint the back, preventing uneven coating and improving product quality. Subsequently... Paint adhering to the ferrous metal smelting product 114 is filtered through two screens 115 and then falls onto the curved plate 222. Because the curved plate 222 is semi-circular and the guide blocks 223 at its four corners are wedge-shaped, it guides the paint flow. Finally, the paint falls into the water tank 228 through the C-shaped water pipe 221, awaiting the next use. When the bottom screen 115 needs cleaning, the user pulls the slide bar 212 using knob 214, which in turn moves the limiting plate 216 fixed to the slide bar 212. At this time, the limiting plate 216 compresses the spring 213, and simultaneously the slide bar 212 moves the locking block 215 fixed to it. When the locking block 215 is no longer in contact with the locking block 211, the paint is cleaned.The filter screen 115 at the bottom can be pulled to detach it from the housing 1 for cleaning. Once cleaning is complete, the filter screen 115 can be held and pushed into the housing 1. The first locking block 211 on both sides of the filter screen 115 presses against the second locking block 215 via its inclined surface. The inclined surface of the second locking block 215 pushes the sliding rod 212, causing the limiting plates 216 to move away from each other. This compresses the spring 213. When the first locking block 211 and the second locking block 215 are no longer pressed together, the spring force of the spring 213 will cause the second locking block 215 to reset, thus fixing the bottom filter screen 115 in place. Additionally, the top filter screen 115 can be cleaned periodically by the operator.
