Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, and in particular to a rust-proof spraying treatment device for the surface of metal parts. Background Technology

[0002] In modern industrial production, metal parts are widely used in various fields due to their excellent mechanical properties. However, metal parts are highly susceptible to corrosion from environmental factors during use, reducing their service life and performance. Therefore, rust-proofing spraying is a crucial step in ensuring the quality of metal parts. Currently, rust-proofing spraying equipment for metal parts faces the following main problems in practical applications:

[0003] On the one hand, existing rust-preventive spraying equipment mostly uses fixed spraying tables, making it difficult to achieve multi-angle, all-around spraying after metal parts are placed on them. During the spraying process, some parts have blind spots, resulting in uneven coating, reduced rust prevention effect, and impact on the protective performance and service life of metal parts. On the other hand, some spraying equipment with part rotation functions has a complex structure, relying on additional drive motors, transmission mechanisms, and other components. This not only increases equipment costs and maintenance difficulty but also occupies a large amount of installation space, hindering large-scale production applications. Furthermore, in existing equipment, the conveying and rotation control of parts are often independent during the spraying process, lacking an effective linkage mechanism, resulting in low spraying efficiency and failing to meet the demands of efficient and automated production.

[0004] Therefore, how to design a rust-proof spraying treatment device that is simple in structure, low in cost, and capable of achieving all-round uniform spraying of metal parts has become a problem that urgently needs to be solved by those skilled in the art. The rust-proof spraying treatment device for metal parts proposed in this utility model solves the above-mentioned problems in the prior art by innovatively designing the spraying table structure and using the meshing transmission of gears and racks to realize the automatic rotation of parts on the spraying table through gear and rack meshing transmission.

[0034] Please see Figure 1-7 This utility model provides a technical solution: a metal parts surface anti-rust spraying treatment device, including a base 1, a metal parts conveyor belt 3 installed on the upper end of the base 1, a spraying chamber 2 fixedly connected to the upper end of the base 1, and a metal parts adjusting assembly. The metal parts adjusting assembly is disposed on the base 1 and includes a limiting block 20, which is fixedly connected to the belt surface of the metal parts conveyor belt 3. A metal parts spraying table 21 is provided inside the limiting block 20, and a connecting shaft 22 is rotatably connected to the upper end of the metal parts spraying table 21. A gear 2 is fixedly connected to the surface of the connecting shaft 22. 4. A metal part support platform 23 is fixedly connected to the upper end of the connecting shaft 22. A rack 5 and a first guide plate 8 are provided on the inner wall of the spraying chamber 2. Multiple first connecting frames 4 and multiple second connecting frames 7 are fixedly connected to the opposite sides of the rack 5 and the first guide plate 8, respectively. The multiple first connecting frames 4 and multiple second connecting frames 7 are all fixedly connected to the inner wall of the spraying chamber 2. A second guide plate 6 for limiting the metal part spraying platform 21 is fixedly connected to the lower end of the rack 5 and the first guide plate 8. The front sides of the rack 5, the first guide plate 8 and the two second guide plates 6 are all bent outwards. The rack 5 meshes with the gear 24.

[0035] Multiple sets of limit blocks 20, metal parts spraying tables 21, connecting shafts 22, metal parts support tables 23, and gears 24 are all installed on the metal parts conveyor belt 3.

[0036] A spraying machine 9 is installed at the upper end of the spraying chamber 2. The spraying machine 9 has a paint tank and a paint pump installed inside. A paint pipe is connected between the inlet end of the paint pump and the paint tank. Two paint connecting pipes 11 are fixedly connected to the outlet end of the paint pump. A spray pipe 12 is fixedly connected to the end of each of the two paint connecting pipes 11 away from the spraying machine 9. A nozzle is fixedly connected to the surface of each of the two spray pipes 12.

[0037] A first guide frame 13 is fixedly connected to the right side of the inner wall of the spraying chamber 2. A first drive motor 14 is fixedly connected to the front end of the first guide frame 13. A threaded rod 15 is fixedly connected to the output end of the first drive motor 14. The threaded rod 15 is rotatably connected to the first guide frame 13. Two first movable blocks 16 are threadedly sleeved on the surface of the threaded rod 15. Both first movable blocks 16 are slidably connected to the first guide frame 13. Two spray pipes 12 are fixedly connected to the corresponding first guide frames 13. The opening of the first guide frame 13 faces downward.

[0038] A second guide frame 17 is fixedly connected to the left side of the inner wall of the spraying chamber 2. A guide rod 18 is fixedly connected to the inner wall of the second guide frame 17. Two second movable blocks 19 are slidably sleeved on the surface of the guide rod 18. Both second movable blocks 19 are slidably connected to the second guide frame 17. Two spray pipes 12 are fixedly connected to the corresponding second movable blocks 19 respectively. The opening of the second guide frame 17 faces downward.

[0039] The upper end of the spraying chamber 2 is provided with a through groove 10 for placing the paint connecting pipe 11.

[0040] Multiple anti-slip strips are fixedly connected to the surface of the metal parts conveyor belt 3, and multiple anti-slip strips are also fixedly connected to the lower end of the metal parts spraying table 21.

[0041] When using the device, the metal parts are placed on the metal parts support platform 23 and move towards the spraying chamber 2 along with the metal parts conveyor belt 3; the anti-slip strips on the surface of the metal parts conveyor belt 3 cooperate with the anti-slip strips at the lower end of the metal parts spraying platform 21 to increase friction and ensure that the parts are stable and do not slip during the conveying process.

[0042] When the metal parts spraying station 21 moves into the spraying chamber 2 along with the conveyor belt, the gear 24 on the connecting shaft 22 gradually contacts and meshes with the rack 5 on the inner wall of the conveyor belt. Since the rack 5 is fixed to the inner wall of the conveyor belt and its position is fixed, the gear 24 is forced to rotate around the connecting shaft 22 during the movement with the conveyor belt, thereby driving the metal parts support station 23 and the parts to rotate synchronously.

[0043] The front sides of the rack 5, the first guide plate 8, and the two second guide plates 6 are all bent outward to form a guiding structure, which allows the gear 24 to smoothly engage and disengage, avoiding impact. The meshing length between the gear 24 and the rack 5 can be adjusted by changing the conveyor belt speed or the rack length to control the number of rotations of the parts, achieving 360° no-dead-angle spraying.

[0044] The limiting block 20 is fixed to the surface of the metal parts conveyor belt 3, and the limiting block 20 is made of flexible material, which makes it easy to limit the lateral position of the metal parts spraying station 21 and prevent the parts from shifting; the rack 5 and the second guide plate 6 at the lower end of the first guide plate 8 limit the metal parts spraying station 21 from below, ensuring that the gear 24 and the rack 5 always maintain the correct meshing posture and avoid the spraying station shaking.

[0045] The paint pump inside the sprayer 9 draws in the anti-rust paint from the paint tank through the paint pipe, pressurizes it, and then delivers it to the spray pipe 12 through the paint connection pipe 11, and finally sprays it out from the nozzle to form a mist coating.

[0046] The first drive motor 14 drives the threaded rod 15 to rotate. Since the two first movable blocks 16 are threadedly connected to the threaded rod 15 and slidably engaged with the first guide frame 13, when the threaded rod rotates, the two first movable blocks 16 move along the first guide frame 13, driving the spray pipe 12 fixed thereto to move up and down, so as to achieve spray coating coverage on the upper surface and sides of the part.

[0047] The guide rod 18 is fixed to the inner wall of the second guide frame 17, and the two second movable blocks 19 can slide along the guide rod 18. When the conveyor belt drives the parts to move, the second movable blocks 19 slide passively on the guide rod 18 with the nozzle 12 to adapt to the position changes during the parts conveying process and ensure that the left nozzle is always aligned with the side of the parts.

[0048] The through channel 10 is located at the upper end of the conveyor belt to accommodate the paint connecting pipe 11, thereby preventing interference between the pipe and the moving parts of the conveyor belt and keeping the inside of the device clean.

[0049] Furthermore, by utilizing the traveling power of the metal parts conveyor belt 3, the parts are automatically rotated through the meshing of the gear 24 and the fixed rack 5. This design eliminates the need for an additional power source, reduces the number of components such as drive motors and couplings, lowers equipment costs, reduces maintenance points for the power source, and reduces energy consumption. For small and medium-sized enterprises in mass production scenarios, it can significantly reduce initial equipment investment and long-term operation and maintenance costs, and is especially suitable for workshop environments with limited budgets or space constraints.

[0050] When the metal parts move with the conveyor belt 3, the gear 24 meshes with the rack 5 to achieve 360° continuous rotation. Combined with the dynamic adjustment of the spray pipes 12 on both sides of the spray chamber 2, the blind spots of traditional fixed spraying, such as the top surface, sides, and edges, are completely eliminated.

[0051] The right-side spray nozzle 12 drives the threaded rod 15 through the first drive motor 14, which in turn drives the first movable block 16 to reciprocate, precisely covering the upper surface and sidewalls of parts of different heights; the left-side spray nozzle 12 passively adapts to the lateral displacement of the parts through the sliding cooperation of the guide rod 18 and the second movable block 19, ensuring that the side spraying distance is always kept within the optimal range, avoiding uneven coating thickness caused by spacing fluctuations, and improving product quality.

[0058] Support platform 23: directly supports metal parts, and rotates with connecting shaft 22 to achieve 360° rotation of parts, ensuring no dead angles in the spraying;

[0059] Connecting shaft 22: connects support platform 23 and gear 24, transmits the rotational power of the gear to the part, and realizes the rotation of the part;

[0060] Gear 24: meshes with the fixed rack 5, converting the linear motion of the conveyor belt 3 into its own rotational motion, and is the core transmission component for unpowered self-rotation;

[0061] Rack 5: Fixed to the inner wall of the spray chamber 2, it meshes with gear 24 to drive the rotation of the parts; the front end is bent to form a guide structure to ensure that the gear smoothly engages / disengages and avoids impact;

[0062] First guide plate 8: It is arranged in parallel with rack 5 and fixed to the inner wall of spray chamber 2 by second connecting frame 7, which helps to limit the lateral position of spray table 21 and enhance stability;

[0063] Second guide plate 6: Fixed to the lower end of rack 5 and first guide plate 8, it rigidly limits the spraying table 21 from below, ensuring that gear 24 and rack 5 always maintain the correct meshing posture and preventing the spraying table from shaking.

[0064] Sprayer 9: It has a built-in paint tank and paint pump. It draws in paint through the paint pipe and pressurizes it. The paint is then delivered to the spray pipe 12 through the paint connection pipe 11 to provide spraying power.

[0065] Paint connecting pipe 11: transmits paint to spray pipe 12, and is stored in the upper end of spray chamber 2 through through groove 10 to avoid interference with moving parts;

[0066] Spray nozzle 12 and spray head: atomize the paint and spray it out to cover the surface of the metal parts; the spray head angle can be adjusted according to the shape of the parts to ensure accurate spraying trajectory;

[0067] First guide frame 13: Installs first drive motor 14 and threaded rod 15, drives first movable block 16 to drive nozzle 12 to reciprocate vertically, covering the upper surface of part and sidewalls of different heights;

[0068] Second guide frame 17: Built-in guide rod 18, second movable block 19 drives the nozzle 12 to slide passively laterally, adapting to the position change during the part transportation process and ensuring a constant side spraying distance;

[0069] Channel 10: Receives paint connecting pipe 11, prevents pipe from contacting and wearing with moving parts of conveyor belt 3, keeps the inside of the device clean, and facilitates maintenance;

[0070] Anti-slip strips: Anti-slip strips (with rough surface treatment) are installed on both the conveyor belt 3 and the lower end of the spray table 21;
