Description

Technical Field

[0001] This application relates to the field of fiberboard nail processing technology, and in particular to a rust-proof coating device for fiberboard nail bodies. Background Technology

[0002] Fiberboard nails are fasteners manufactured through a heat treatment process, primarily used for connecting and securing wood panels to each other or to thin steel sheets. In modern construction, furniture manufacturing, and decoration industries, fiberboard nails are commonly used connectors, and their rust-resistant properties directly affect their safety and durability. Therefore, applying rust-proof paint to the nail body is a crucial step in the manufacturing process.

[0003] In related technologies, the traditional methods of rust-proofing coating for fiberboard nails mainly include manual brushing and unidirectional mechanical spraying or dipping. Manual brushing relies on manual operation, which is not only inefficient and difficult to meet the needs of large-scale production, but also results in uneven coating thickness and the tendency for missed coating, leading to poor rust prevention. Although mechanical spraying or dipping can improve production efficiency, the unidirectional coating method has obvious defects. For example, during spraying, some nails cannot be covered by the rust-proof paint due to the angle. After dipping, the rust-proof paint on the nail surface is unevenly distributed, which can easily lead to problems such as dripping and accumulation. Similarly, it is impossible to guarantee the uniformity and integrity of the coating, thereby reducing the rust prevention performance of the fiberboard nails.

[0004] Therefore, we propose a rust-proof coating device for fiberboard nail bodies to solve the above problems. Utility Model Content

A higher conveyor belt 6 is tensioned and sleeved on the multiple upper conveyor rollers 5. Rust-proof paint application felts 7 are fixedly connected to the outer surfaces of both the lower and upper conveyor belts 4 and 6. The lower and upper conveyor belts 4 and 6 respectively drive the corresponding rust-proof paint application felts 7 to rotate synchronously relative to each other. Utilizing the synchronous relative rotation of the two rust-proof paint application felts 7, the fiberboard nails can be conveyed horizontally in a straight line. Simultaneously, it can achieve all-round and uniform rust-proof paint coating on the fiberboard nail body. Compared with the traditional single-direction coating method, it avoids the problems of missed coating and uneven coating, effectively improving the coating quality and rust-proof effect, and increasing the coating efficiency. The rust-proof paint application felts... 7 can be made of polyester fiber felt. The uniform pore structure of polyester fiber felt can effectively store and release anti-rust paint, ensuring the uniformity and stability of the coating. It is suitable for high-intensity and long-term coating work. The space below the lower conveyor belt 4 in the coating box 2 is used to hold anti-rust paint. A drive assembly is set on the rear side of the coating box 2. The drive assembly is used to control the lower conveyor belt 4 and the upper conveyor belt 6 to rotate synchronously in opposite directions. The drive assembly includes two gears 8 and a motor 9. The rear end of one upper conveyor roller 5 and the rear end of one lower conveyor roller 3 both extend outside the coating box 2. The two gears 8 are fixedly installed on the rear end of the upper conveyor roller 5 and the rear end of the lower conveyor roller 3, respectively. The motor 9 is set at the rear end of the gears 8. The output shaft end of the motor 9 is fixedly connected to the rear end of the lower conveyor roller 3. The motor 9 can be used to drive the lower conveyor roller 3 to rotate. Under the meshing transmission of the two gears 8, the lower conveyor roller 3 and the upper conveyor roller 5 can rotate simultaneously, thereby realizing the synchronous relative rotation of the lower conveyor belt 4 and the upper conveyor belt 6. Figure 2 From the perspective of the upper conveyor roller 5, it rotates counterclockwise, while the lower conveyor roller 3 rotates clockwise.

[0024] In this embodiment, a support base 10 is fixedly installed on the rear outer wall of the paint box 2, and the motor 9 is fixedly installed on the support base 10, which can stably support the motor 9.

[0025] In this embodiment, a rust-preventive paint conveying assembly is provided on the rear side of the coating box 2. The rust-preventive paint conveying assembly is used to convey the rust-preventive paint to the surfaces of the two rust-preventive paint coating felts 7. The rust-preventive paint conveying assembly includes a conveying pump 11, a suction pipe 12, a discharge pipe 13, a U-shaped pipe 14, and two hollow liquid distribution plates 15. The conveying pump 11 is fixedly installed on the rear outer wall of the coating box 2. One end of the suction pipe 12 is fixedly connected to the suction end of the conveying pump 11, and the other end of the suction pipe 12 extends into the coating box 2 and is located below the lower conveyor belt 4. One end of the discharge pipe 13 is fixedly connected to the discharge end of the conveying pump 11, and the U-shaped pipe 14 is fixedly connected to the other end of the discharge pipe 13. One of the hollow liquid distribution plates 15 is fixedly installed on the rear outer wall of the coating box 2. Installed on the top inner wall of the coating box 2, another hollow liquid distribution plate 15 is installed and fixed inside the coating box 2 and located below the lower conveyor belt 4. Both ends of the U-shaped tube 14 extend into the corresponding hollow liquid distribution plate 15. Multiple anti-rust paint discharge holes 16 are arranged in an array on the side of the two hollow liquid distribution plates 15 that are close to each other. By using the operation of the conveying pump 11, the anti-rust paint at the bottom of the coating box 2 can be circulated to the two hollow liquid distribution plates 15, and then evenly distributed to the two anti-rust paint coating felts 7 through the anti-rust paint discharge holes 16, so as to realize the recycling of anti-rust paint, avoid the accumulation and waste of anti-rust paint, and reduce production costs. The end of the suction tube 12 located inside the coating box 2 is immersed in the anti-rust paint.

[0026] In this embodiment, a cleaning port is provided on the front side wall of the paint coating box 2, and a cleaning door 17 is fixedly installed on the front side wall of the paint coating box 2 by screws. The cleaning door 17 is adapted to the cleaning port to facilitate cleaning the inside of the paint coating box 2.

[0027] In this embodiment, a feed inlet 18 is provided on the left side wall of the coating box 2 to facilitate the placement of fiberboard nails between two anti-rust paint coating felts 7. An inclined discharge channel 19 is fixedly installed on the right side wall of the coating box 2 to discharge the fiberboard nails coated with anti-rust paint.

[0028] In this embodiment, multiple evenly distributed electric heating strips 20 are fixedly installed on the top inner wall of the discharge channel 19. The heat generated by the electric heating strips 20 can be used to heat and dry the fiberboard nailing machine coated with anti-rust paint, thereby accelerating the drying and solidification of the anti-rust paint.

[0029] In this embodiment, a residual discharge pipe 21 is fixedly connected to the bottom right side of the paint box 2, and a residual discharge valve 22 is fixedly installed on the residual discharge pipe 21 to facilitate the discharge of anti-rust paint for replacement.

[0030] In this embodiment, an observation window 23 located above the cleaning door 17 is fixedly installed on the front side wall of the paint coating box 2, which allows for convenient observation of the working conditions inside the paint coating box 2.

[0031] In this embodiment, it should be noted that the motor 9, the delivery pump 11, and the electric heating strip 20 are all commercially available, and their wiring connection methods and control methods are mature technologies in this field and have been fully disclosed, so they will not be described in detail here.

[0032] With the above structure, the fiberboard nail anti-rust coating device provided in this application operates by simultaneously starting the motor 9 and the conveying pump 11. The output shaft of the motor 9 drives the lower conveyor roller 3, which is fixedly connected to it, to rotate. Under the meshing transmission of the two gears 8, the lower conveyor roller 3 and the upper conveyor roller 5 can rotate simultaneously, thereby realizing the synchronous relative rotation of the lower conveyor belt 4 and the upper conveyor belt 6. This causes the two anti-rust coating felts 7 to rotate with the lower conveyor belt 4 and the upper conveyor belt 6 respectively. At the same time, when the conveying pump 11 is running, the suction pipe 12 carries the anti-rust coating material to the nail body. The anti-rust paint contained in the paint box 2, located below the lower conveyor belt 4, is drawn up and transported through the discharge pipe 13 and U-shaped pipe 14 to two hollow liquid distribution plates 15. The anti-rust paint entering the hollow liquid distribution plates 15 is discharged from multiple anti-rust paint discharge holes, and can then be evenly discharged onto two anti-rust paint coating felts 7, keeping the anti-rust paint coating felts 7 always wet. Unused anti-rust paint drips back to the bottom of the paint box 2 and is drawn back by the suction pipe 12 for recycling, avoiding waste of anti-rust paint, reducing production costs, and maintaining the continuity of the painting process. By inserting the fiberboard nails into the space between two anti-rust paint coating felts 7 through the feed port 18 on the left side of the paint box 2, and using the upper conveyor belt 6 and the lower conveyor belt 4 to drive the corresponding anti-rust paint coating felts 7 to rotate, the two anti-rust paint coating felts 7 can form a clamping and conveying structure for the fiberboard nails. Under the action of friction, the fiberboard nails are stably and horizontally conveyed in a straight line. At the same time, the anti-rust paint impregnated on the two anti-rust paint coating felts 7 is evenly coated on the surface of the nail body, thus realizing the all-round and dead-angle-free painting process of the fiberboard nails. Compared with the traditional unidirectional painting, it ensures the uniformity and integrity of the coating. The fiberboard nails coated with anti-rust paint are discharged through the discharge channel 19 on the right. Multiple electric heating bars 20 are turned on. The electric heating bars 20 at the top of the discharge channel 19 generate heat, which can preliminarily dry the fiberboard nails during the discharge process, accelerate the curing of the anti-rust paint, and effectively shorten the waiting time for subsequent processing.
