Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a spraying device for strengthening the surface of chains. Background Technology

[0002] In industrial production, chains, as an important transmission component, are widely used in various mechanical equipment. To improve the wear resistance, corrosion resistance, and service life of chains, surface strengthening treatment is required, and spraying is a common and effective surface treatment method. The performance of spraying equipment used for chain surface strengthening directly affects the quality of the chains and production efficiency; therefore, developing high-performance, stable, and reliable spraying equipment is of significant practical importance.

[0003] Currently, in chain surface strengthening coating operations, common spraying equipment typically employs relatively conventional mechanical structures and technical principles. Generally, paint or coating materials are sprayed at a certain pressure through fixed nozzles, and then the chain's uniform movement on a conveyor belt achieves coating of the chain surface. Its basic principle is based on a simple pressure difference, where paint from a storage container is transported through pipes to the nozzle, forming a mist or linear paint stream that evenly covers the chain surface.

[0004] However, existing spraying equipment has a significant problem. Because it cannot adjust the paint flow rate, it's difficult to ensure uniform paint coverage at different locations such as chain links and chain connections during actual spraying. This results in some areas having excessively thick paint layers, causing runs, while others have too thin a layer, failing to achieve adequate protection. This severely impacts the surface quality and protective performance of the chain. Therefore, a spraying device for chain surface strengthening treatment is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a spraying device for strengthening the surface of chains, which aims to improve the problem in the prior art that the paint flow rate cannot be adjusted, resulting in some areas having excessively thick paint layers and sagging, while other areas have excessively thin paint layers and cannot achieve a good protective effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spraying device for strengthening the surface of a chain includes a protective shell, a hinge fixedly connected to the side wall of the protective shell, a base fixedly connected to the bottom of the protective shell, a rotating door fixedly connected to the side wall of the hinge, a handle fixedly connected to the side wall of the rotating door, and a connecting pipe fixedly connected inside the protective shell, with an adjustment component provided on the inner wall of the connecting pipe.

[0008] The adjusting assembly includes a second hollow column, the side wall of which is fixedly connected to the inner wall of the connecting pipe. A rotating disk is slidably connected to the inner wall of the second hollow column, and a fixed column is slidably connected to the inner wall of the rotating disk. A triangular rotating plate is fixedly connected to the outer wall of the fixed column. A hollow plate is fixedly connected to the inner wall of the second hollow column, and a support ring is fixedly connected to the side wall of the hollow plate. The outer wall of the fixed column is slidably connected to the inner wall of the hollow plate. A dispersing assembly is provided at the other end of the connecting pipe.

[0009] As a further description of the above technical solution:

[0010] The dispersion assembly includes a dispersion nozzle, the sidewall of which is fixedly connected to one side of the connecting pipe, and the dispersion nozzle is used to disperse the paint.

[0011] As a further description of the above technical solution:

[0012] A drive device is provided on the top of the protective shell, and a linkage rod is fixedly connected to the bottom of the drive device.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the linkage rod is rotatably connected to the inner wall of the protective shell, and a connecting rod is fixedly connected to the outer wall of the linkage rod.

[0015] As a further description of the above technical solution:

[0016] A support plate is fixedly connected to one side of the connecting rod, and a first hollow column is fixedly connected to the top of the support plate.

[0017] As a further description of the above technical solution:

[0018] A spring is installed inside the first hollow column, and one side of the spring is fixedly connected to the side wall of the first hollow column.

[0019] As a further description of the above technical solution:

[0020] The other end of the spring is fixedly connected to a retaining ball, and the outer wall of the retaining ball is slidably connected to the inside of the first hollow column.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, turning the rotating disc causes the triangular rotating plate to rotate. The triangular rotating plate rotates on the inner wall of the hollow plate, which achieves the effect of adjusting the paint flow rate. This solves the problem that the inability to adjust the paint flow rate leads to some areas having an excessively thick paint layer and causing dripping, while other areas have an excessively thin paint layer and cannot achieve a good protective effect. This improves the stability of the spraying equipment for strengthening the surface of the chain.

[0023] 2. In this utility model, the chain is taken out and then placed on the inner wall of the support plate. The pressure on the ball will cause the spring on the side wall to contract. At the same time, the spring generates a thrust to push the ball against the side wall of the chain, achieving the effect of stably clamping the chain. This solves the problem of unstable chain clamping, which causes the chain to shake and results in uneven chain coating. It improves the practicality of the spraying equipment for chain surface strengthening treatment. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a spraying device for strengthening the surface of a chain, including a protective shell 1. The protective shell 1 is made of high-strength stainless steel, which has excellent corrosion resistance and mechanical strength, and can effectively protect the internal components from the influence of the external environment. A hinge 5 is fixedly connected to the side wall of the protective shell 1. The hinge 5 is made of wear-resistant alloy steel to ensure the long-term stable opening and closing of the rotating door 4. A base 3 is fixedly connected to the bottom of the protective shell 1. A rotating door 4 is fixedly connected to the side wall of the hinge 5. The rotating door 4 is made of aluminum alloy, which has both lightweight and high strength characteristics, is easy to operate and durable. A handle 7 is fixedly connected to the side wall of the rotating door 4. A connecting pipe 9 is fixedly connected inside the protective shell 1. The connecting pipe 9 is made of corrosion-resistant polytetrafluoroethylene, which has good chemical stability and low friction coefficient to ensure smooth paint delivery. An adjustment component is provided on the inner wall of the connecting pipe 9.

[0033] The adjustment assembly includes a second hollow column 15, the side wall of which is fixedly connected to the inner wall of the connecting pipe 9. A rotating disk 20 is slidably connected to the inner wall of the second hollow column 15. The rotating disk 20 is made of hard anodized aluminum alloy, which has high surface hardness and wear resistance, ensuring long-term stability. A fixed column 19 is slidably connected to the inner wall of the rotating disk 20. The fixed column 19 is made of quenched steel, which has high strength and wear resistance and can withstand large mechanical stress. A triangular rotating plate 18 is fixedly connected to the outer wall of the fixed column 19. The triangular rotating plate 18 is made of high-strength nylon, which has self-lubricating and impact resistance, and can achieve smooth rotation adjustment. A hollow plate 16 is fixedly connected to the inner wall of the second hollow column 15. A support ring 17 is fixedly connected to the side wall of the hollow plate 16. The support ring 17 is made of wear-resistant copper alloy, which reduces friction loss when the fixed column 19 slides. The outer wall of the fixed column 19 is slidably connected to the inner wall of the hollow plate 16. A dispersion assembly is provided at the other end of the connecting pipe 9.

[0034] Specifically, the connecting pipe 9 is connected to the spraying pipeline, serving as a key channel for paint delivery. Then, the operator operates the rotating disc 20, which slides within the inner wall of the second hollow column 15, achieving smooth rotation. The rotation of the rotating disc 20 causes the fixed column 19, which slides synchronously on its inner wall, to further push the triangular rotating plate 18 on the outer wall, causing it to rotate precisely around its axis. During this process, the fixed column 19 slides along the interior of the hollow plate 16 under force. Through the limiting effect of the hollow plate 16, the movement of the fixed column 19 is effectively constrained, thus achieving a stable motion state. Ultimately, this achieves the effect of regulating the paint flow rate, enabling the spraying equipment to precisely control the paint output according to actual needs, ensuring spraying uniformity and process quality.

[0035] Reference Figure 1 , Figure 2 and Figure 4The dispersion assembly includes a dispersion nozzle 10, which is made of high-hardness tungsten carbide material, possessing excellent wear resistance and corrosion resistance. It can withstand the impact of high-speed paint and achieve uniform dispersion, ensuring consistent spraying results. The side wall of the dispersion nozzle 10 is fixedly connected to one side of the connecting pipe 9. The dispersion nozzle 10 is used to disperse the paint. A drive device 2 is provided on the top of the protective shell 1, and a linkage rod 6 is fixedly connected to the bottom of the drive device 2. The linkage rod 6 is made of quenched alloy steel, possessing high strength and wear resistance, and can withstand large torque and mechanical stress. The outer wall of the linkage rod 6 is rotatably connected to the inner wall of the protective shell 1, and a connecting rod 8 is fixedly connected to the outer wall of the linkage rod 6. The connecting rod 8 is made of high-strength stainless steel. It has excellent tensile strength and corrosion resistance, ensuring the stability and reliability of transmission. A support plate 11 is fixedly connected to one side of the connecting rod 8, and a first hollow column 12 is fixedly connected to the top of the support plate 11. A spring 13 is set inside the first hollow column 12. The spring 13 is made of high elasticity stainless steel wire, which has excellent fatigue resistance and corrosion resistance, and can maintain elasticity and work stably for a long time. One side of the spring 13 is fixedly connected to the side wall of the first hollow column 12, and the other end of the spring 13 is fixedly connected to a ball 14. The ball 14 is made of bearing steel with surface hardening treatment, which has high hardness and wear resistance, and can firmly lock the chain and reduce wear. The outer wall of the ball 14 is slidably connected to the inside of the first hollow column 12.

[0036] Specifically, when using the spraying equipment for chain surface strengthening treatment, the drive device 2 first drives the linkage rod 6 to rotate. The rotation of the linkage rod 6 drives the connecting rod 8 on the side wall to rotate synchronously through the connecting rod 8 on its outer wall, thereby ensuring the coordinated operation of the entire transmission system. When clamping the chain, the chain is first placed on the inner wall of the support plate 11. When the chain contacts the support plate 11, it will feel pressure, which will then drive the locking ball 14 to move. The movement of the locking ball 14 will compress the spring 13 on the side wall, causing it to contract. When the chain position is stable, the spring 13 releases its elasticity, pushing the locking ball 14 out, so that its outer wall is firmly locked onto the side wall of the chain, thereby achieving the effect of stable chain clamping, ensuring the stability of the chain during the spraying process, and improving the quality and efficiency of surface strengthening treatment.

[0037] Working principle: When using the spraying equipment for strengthening the chain surface, the drive device 2 first drives the linkage rod 6 to rotate. The rotation of the linkage rod 6 drives the connecting rod 8 on the outer wall to rotate. The rotation of the connecting rod 8 drives the connecting rod 8 on the side wall to rotate. At the same time, when clamping the chain, the chain is first placed on the inner wall of the support plate 11. Then, after feeling the pressure, the locking ball 14 drives the spring 13 on the side wall to contract. Finally, the spring 13 releases the elastic force, pushing out the locking ball 14, so that its outer wall is locked on the side wall of the chain, achieving the effect of stable chain clamping.

[0038] Next, connect the connecting pipe 9 to the spraying pipe, then turn the rotating disk 20. At the same time, the rotating disk 20 slides on the inner wall of the second hollow column 15. The rotation of the rotating disk 20 causes the fixed column 19 sliding on its inner wall to slide. Then, the sliding of the fixed column 19 causes the triangular rotating plate 18 on the outer wall to rotate. When the fixed column 19 is under force, it slides inside the hollow plate 16 to limit its movement and make it a stable motion, thus achieving the effect of adjusting the paint flow rate.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
