Description

Technical Field

[0001] This utility model relates to the field of diesel engine box manufacturing technology, specifically to a spraying equipment for producing lightweight, high-strength diesel engine boxes. Background Technology

[0002] Lightweight, high-strength diesel engines are a type of diesel engine that utilizes innovative design and cutting-edge technology to reduce its weight while maintaining or improving structural strength and power output. During the manufacturing process of diesel engines, a painting process is required. To ensure the quality of this painting process, the painting equipment used in diesel engine production employs a mixing device to agitate the paint. However, because this agitation directly mixes the paint stored in the paint storage structure, it takes time. To ensure a uniform paint concentration during spraying, after using up the uniformly concentrated paint and adding new paint, the equipment must be paused until the mixing process is complete before spraying can resume. Each restart requires additional time for adjusting equipment parameters and calibrating the spraying position, significantly delaying the entire processing schedule and severely reducing the efficiency of diesel engine painting.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese patent application number 202322619555.1, application date 2023-09-26) provides a spraying device for diesel engine production, including a processing table. The bottom of the processing table is equipped with support legs, vertical plates, a mixing cylinder, a stirring module, a feed hopper, a discharge pipe, a first control valve, a temporary storage tank, and a feed pipe. A discharge pipe is located at the bottom of the temporary storage tank, and a second control valve is installed on the discharge pipe. A spraying module is positioned between the lower ends of two vertical plates, and both vertical plates are welded and fixed to the processing table. This diesel engine spraying device not only meets the basic requirements for spraying diesel engines and ensures a uniform concentration of paint during spraying, thus guaranteeing the quality of the spraying process, but also allows the spraying structure to continuously obtain paint of uniform concentration, enabling continuous operation and ensuring the efficiency of the spraying process.

[0004] Resin is a key component in coating film formation, while solvent is used to adjust the viscosity and drying speed of the coating. If not stirred, the resin will separate from the solvent, affecting the coating performance and drying effect. During the use of the above-mentioned device, it is impossible to ensure that the raw materials can be mixed evenly, resulting in inconsistent color on the surface of the diesel engine box after spraying. Furthermore, it will reduce the adhesion between the coating and the surface of the diesel engine box, thereby reducing the protective effect of the coating on the engine box. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This lightweight, high-strength diesel engine box production spraying equipment adopts a novel structural design, the specific details of which are as follows: This lightweight, high-strength diesel engine box production spraying equipment, through its agitation components and ring gears, can ensure uniform mixing of internal raw materials, preventing sedimentation.

[0014] Furthermore, gear transmission allows for stable paint spraying, helping to maintain a constant coating thickness and appearance quality. In addition, the equipment is reliable in operation, reducing downtime due to malfunctions and increasing the effective operating time of the equipment.

[0015] This lightweight, high-strength diesel engine box production spraying equipment, through the installation of sliding blocks and limit rods, can maintain a stable pressure environment for the paint flow inside the spraying pipeline.

It can not only disperse the impact force from the outside and prevent the equipment from being deformed due to excessive local stress, but also ensure that the equipment structure remains stable. At the same time, it can reduce the damage of resonance to the stability of the equipment and extend the service life of the equipment. Attached Figure Description

Detailed Implementation

[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] Example 1: The spray gun 1, mixing tank 3, and top plate 2 can disperse external impact forces, preventing excessive local stress and deformation of the equipment. Figures 1-2 As shown: It includes a spraying frame 1 and a stirring assembly 11. A top plate 2 is fixedly connected to the upper end of the spraying frame 1, and a mixing tank 3 is fixedly connected to the upper surface of the top plate 2. A support frame 5 is fixedly connected to the inner wall of the mixing tank 3. Meanwhile, a spraying assembly 4 is fixedly connected to the lower end of the top plate 2. A ring gear 13 is fixedly connected to the inner wall of the mixing tank 3. The stirring assembly 11 is rotatably disposed inside the mixing tank 3, and a fixed gear 12 is fixedly connected to the surface of the stirring assembly 11. The fixed gear 12 and the ring gear 13 are meshed. A limit rod 19 is provided on the inner wall of the mixing tank 3 through a reciprocating sliding assembly. The limit rod 19 is symmetrically distributed about the center of the mixing tank 3, and a baffle 20 is slidably connected through the limit rod 19. Meanwhile, a sliding block 18 is fixedly connected to the surface of the baffle 20.

[0028] The operator pushes the spray gun 1 to the appropriate position and uses a conveying device to transport the raw materials into the mixing tank 3. At this point, the operator starts the motor 6, and the output shaft 7 drives the agitator 11 to rotate inside the mixing tank 3, agitating the internal raw materials (e.g., ...). Figure 1 and Figure 3 As shown), this avoids situations where the coating is too thick or too thin due to excessively long or short local spraying time. Simultaneously, the bevel gear 15 causes the sliding block 18 to slide back and forth inside the mixing box 3, ensuring uniform spraying by the spray gun (as shown). Figure 6 As shown in the figure, the resulting coating has a uniform thickness and a smooth surface, improving the overall quality of the product.

[0029] In Example 2, unlike Example 1, the support frame 5, connecting plate 8, and fixing rod 9 ensure uniform mixing of the internal raw materials, preventing sedimentation and avoiding excessively thick or thin coatings due to excessively long or short local spraying times. Figures 3-5 As shown: A motor 6 is fixedly connected to the upper outer side of the mixing box 3, and a rotating shaft 7 is fixedly connected to the output end of the motor 6. The rotating shaft 7 is rotatably disposed inside the support frame 5. A connecting plate 8 is fixedly connected to the surface of the rotating shaft 7. The connecting plate 8 is rotatably disposed inside the mixing box 3. A fixing rod 9 is fixedly connected inside the connecting plate 8. A connecting frame 10 is fixedly connected to the surface of the fixing rod 9 near the lower end of the connecting plate 8. The connecting plate 8 is rotatably disposed inside the mixing box 3. An agitator 11 is rotatably disposed inside the connecting frame 10.

[0030] When the motor 6 rotates, it drives the output shaft 7 to rotate inside the support frame 5, and also drives the connecting plate 8 on the surface of the shaft 7 to rotate inside the mixing box 3 (e.g., Figure 3 As shown), the continuous rotation of the connecting plate 8 drives the fixed rod 9 fixed on the surface to rotate, causing the connecting frame 10 on the surface of the fixed rod 9 to drive the internal stirring assembly 11 to rotate inside the mixing box 3, and causing the fixed gear 12 on the surface of the stirring assembly 11 to mesh with the ring gear 13 on the inner wall of the mixing box 3 (as shown). Figure 4 and Figure 5 As shown), the agitator 11 rotates inside the connecting frame 10, thereby agitating the raw materials inside the mixing tank 3. This helps maintain a constant coating thickness and appearance quality, and the equipment operates reliably, reducing downtime and increasing the effective operating time of the equipment.

[0031] In Example 3, unlike Example 2, the transmission shaft 14, cylinder 16, and connecting rod 17 ensure a stable pressure environment for paint flow within the spraying pipeline. This stable pressure prevents pigment particles in the paint from agglomerating due to sudden pressure changes. Figures 6-7 As shown: A drive shaft 14 is rotatably installed inside the mixing tank 3, and bevel gears 15 are fixedly connected to both the surface of the drive shaft 14 and the surface of the rotating shaft 7. The reciprocating sliding assembly includes a cylinder 16 fixedly connected to the surface of the drive shaft 14. The cylinder 16 is rotatably installed inside the mixing tank 3, and one end of the connecting rod 17 is slidably connected to the cylinder 16. The other end of the connecting rod 17 is slidably connected to a sliding block 18. The sliding block 18 is slidably installed inside the mixing tank 3, and the surface of the sliding block 18 near the spraying assembly 4 is arc-shaped.

[0032] Both the drive shaft 14 and the rotating shaft 7 are equipped with bevel gears 15. As the rotating shaft 7 rotates, it drives the drive shaft 14 to rotate inside the mixing box 3 (e.g., ...). Figure 6As shown), it drives the cylinder 16 on the surface to rotate. As the cylinder 16 rotates, it drives the connecting rod 17 sleeved on the surface to slide on the surface. At the same time, it drives the sliding block 18 sleeved on the other end of the connecting rod 17 to slide back and forth inside the mixing box 3 under the constraint of the limiting rod 19 (as shown). Figure 7 As shown, the discharge port of the device is made anti-clogging and sliding to reduce the damage to the equipment caused by pressure fluctuations due to blockage, and to improve the stability and reliability of the equipment operation.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
