Description

TECHNICAL FIELD

[0001] The present application relates to the chain processing technical field, specifically to a chain processing device for uniform chain painting. BACKGROUND

[0002] In the field of chain processing, painting is one of the key processes to improve the corrosion resistance of the chain, prolong the service life and optimize the appearance. The chain painting equipment on the market is mainly divided into manual brushing and semi-automatic mechanical painting, but both have obvious technical defects:

[0003] Manual brushing relies on the experience of the operator, which not only has high labor intensity and low production efficiency, but also cannot guarantee the uniformity of the paint application, and is prone to local paint leakage and uneven paint layer, resulting in poor surface flatness of the chain and easy loss of protection effect due to paint layer falling off in subsequent use; at the same time, manual operation will cause paint waste and paint mist diffusion to pollute the working environment, which does not meet the green production demand.

[0004] Most of the semi-automatic mechanical painting equipment adopts immersion or single brushing structure. The chain surface is coated with too much paint after immersion, which is prone to sagging and accumulation, and additional paint scraping and drying processes are required, which is complicated and further affects the uniformity of the paint layer. The single brushing equipment has the problems of loose fit between the feeding brush and the chain and asynchronous transmission of the chain and paint supply, which leads to insufficient brushing of the chain side, gap and other parts, resulting in dead angles in painting. In addition, the existing equipment generally lacks paint anti-settling design, and the paint is prone to stratification and sedimentation after long-term standing, which makes the paint concentration on the chain uneven, affecting the protection performance and appearance consistency; and the equipment has poor adaptability and cannot meet the painting needs of different specifications of chains, and the operation flexibility is insufficient. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a chain processing device for uniform chain painting, which solves the problems mentioned in the background art.

The storage box and the feeding brush are connected through a discharge pipe.

[0008] When the air supply and extraction device is started, air is supplied to the air guide frame. As the air pressure increases, it first pushes the two feeding brushes to move relative to each other until they come into contact. At this time, the air supply and extraction device continues to supply air, and the excess gas enters the storage box to push the pressure plate down, so that the pressure plate squeezes the paint through the discharge pipe to immerse the feeding brush.

[0009] A connecting rope is wound around one side of the second gear. One end of the connecting rope extends into the storage box and is fixedly connected to the pressure plate. When the pressure plate moves down, the second gear rotates synchronously through the connecting rope, causing the chain meshing on its outer side to rotate and be painted.

[0011] An electric push rod is also fixedly installed on the side wall of the support frame, and the output end of the electric push rod is fixedly installed with the guide block.

[0012] Preferably, a connecting plate is fixedly provided on the base, a connecting column is rotatably provided through the connecting plate, the second gear is fixedly provided at the end of the connecting column, and the connecting rope is wrapped around the outside of the connecting column.

[0013] Preferably, a torsion spring is fixedly provided between the outer surface of the connecting column and the connecting plate.

[0014] Preferably, baffles are symmetrically and rotatably arranged at the connection between the air guide frame and the storage box, and when the two baffles are in a horizontal state, they are sealed and fitted together on opposite sides.

[0015] The baffle is rotatably mounted at the connection between the air guide frame and the storage box via a pin, and a coil spring is sleeved on the outer surface of the pin. When there is no external force, the coil spring keeps the baffle in a horizontal state.

[0016] Preferably, a rubber baffle is fixedly installed at the connection between the storage box and the discharge pipe, and a cross groove is formed through the rubber baffle.

[0017] Preferably, an air supply channel is fixedly provided on the outside of the storage box, one side of the air supply channel is connected to the air guide frame, and the feeding brush is slidably disposed on the other side of the air supply channel.

[0018] Preferably, a sliding rod is fixedly provided on the side of the feeding brush near the air conveying channel. The sliding rod passes through and extends into the interior of the air conveying channel. A sealing piston is fixedly provided at the end of the sliding rod. The sealing piston is slidably and sealingly disposed with the inner surface of the air conveying channel.

[0019] Preferably, both the feeding brush and the sliding rod are hollow, and the end of the sliding rod is connected to the interior of the feeding brush, the bottom end of the discharge pipe is connected to the interior of the sliding rod, and the bristles on the feeding brush are connected to the interior of the feeding brush.

[0020] Preferably, a transmission rod is rotatably arranged inside the storage box, the transmission rod passes through the pressure plate, a spiral blade is fixedly arranged on the bottom outer surface of the transmission rod, a spiral groove is opened on the outer surface of the transmission rod, and a protrusion is fixedly arranged inside the pressure plate, the protrusion extends into the spiral groove and is fitted against its inner wall.

[0021] Beneficial effects

[0022] This invention provides a chain processing device for uniformly coating chains. Compared with the prior art, it has the following advantages:

[0023] (1) The chain processing device that allows the chain to be painted evenly uses air pressure to drive two feeding brushes to move synchronously relative to each other and clamp the chain. The tight fit between the chain and the feeding brush ensures that there are no dead corners in the painting on both sides and gaps of the chain. At the same time, the pressure plate moves down at a constant speed under air pressure to provide stable pressure for the paint. The hollow feeding brush enables the paint to penetrate evenly, avoiding paint accumulation or missed coating. The spiral blades in the storage box rotate synchronously with the pressure plate as it moves down, continuously stirring the paint, effectively preventing paint sedimentation and stratification, ensuring consistent paint concentration, and ultimately making the paint layer on the chain surface uniform in thickness and high in flatness.

[0024] (2) The chain processing device that allows the chain to be painted evenly achieves an automated process of "feeding brush clamping - paint supply - chain rotation - painting completion - equipment reset" through the linkage design of the air supply and extraction equipment and the mechanical structure. No manual intervention is required in the painting process, which greatly reduces labor intensity. During the painting process, the pressure plate moves down and the chain rotates synchronously. The paint supply and chain transmission rhythm are precisely matched to avoid unnecessary waiting. Compared with manual painting and traditional semi-automatic equipment, the production efficiency is increased by more than 30%. During the chain replacement stage, the air supply and extraction equipment quickly releases the feeding brush, and the electric push rod adjusts the gear spacing to achieve rapid loading and unloading of the chain, further shortening the process cycle.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-8This invention provides a technical solution: a chain processing device for uniformly coating chains, comprising a base 1 and a support frame 2 fixedly mounted on the base 1. A storage box 3 for holding paint is fixedly mounted on the support frame 2. The storage box 3 has a pressure plate 4 inside which the paint is squeezed out. The storage box 3 stores paint to provide raw material for coating. Its internal space and the pressure plate 4 form a sealed cavity to ensure that the air pressure can effectively push the pressure plate 4 to squeeze the paint. The pressure plate 4 moves downward at a uniform speed under the action of air pressure, generating stable pressure on the paint, so that the paint is continuously and uniformly output through the discharge pipe 9, avoiding uneven coating thickness caused by inconsistent paint supply. The base 1 is equipped with gear 5 and gear 6 for limiting and supporting the chain. The symmetrical arrangement of gears 5 and 6 forms a chain support and meshing structure. The tooth profile of the gears matches the chain pitch, both limiting the chain to prevent it from shifting or falling off during painting, and driving the chain to move at a uniform speed through gear rotation, ensuring that every part of the chain makes full contact with the application brush 7, avoiding localized paint leakage. The storage box 3 is symmetrically equipped with two application brushes 7. When closed, the two brushes fit against both sides of the chain, cooperating with the chain's rotation to... The chain is now fully coated with paint in all directions, with no dead corners. The top of the storage box 3 is connected to and fixedly installed with an air guide frame 8, which is a pressure distribution and buffer chamber. The top of the air guide frame 8 is connected to an air inlet 801, which is connected to an external air supply and extraction device to achieve stable gas input. One side of the feeding brush 7 is connected to the air guide frame 8. The storage box 3 and the feeding brush 7 are connected through a discharge pipe 9. One side of the gear 6 is wrapped with a connecting rope 10, one end of which extends into the storage box 3 and is fixedly connected to the pressure plate 4.

[0036] In this technical solution, automatic and uniform painting of the chain is achieved by pneumatically driving the linkage mechanical action. The core process is as follows: the air extraction equipment is filled with air → the feeding brush 7 is pushed to close and clamp the chain → the air pressure continues to increase to drive the pressure plate 4 to move down to supply paint → the pressure plate 4 is linked with the gear to drive the chain to rotate → the feeding brush 7 completes the all-round painting simultaneously. The cooperation of each structure ensures the uniformity of painting and the degree of automation.

[0037] As a further technical solution, a rubber baffle 18 is fixedly installed at the connection between the storage tank 3 and the discharge pipe 9, and a cross groove is opened through the rubber baffle 18. The cross groove is designed to close naturally when there is no pressure, preventing the paint from flowing back or leaking when not in operation; when the pressure plate 4 squeezes the paint, the paint pressure overcomes the elastic resistance of the rubber baffle 18 and flows evenly into the discharge pipe 9 through the cross groove, while also playing a buffering and pressure stabilizing role, making the paint output more stable.

[0038] When the air supply and extraction equipment is started, air is supplied to the air guide frame 8. As the air pressure increases, it first pushes the two feeding brushes 7 to move relative to each other until they come into contact. At this time, the air supply and extraction equipment continues to supply air. Excess gas enters the storage box 3 and pushes the pressure plate 4 down, so that the pressure plate 4 squeezes the paint through the discharge pipe 9 to immerse the feeding brush 7. When the pressure plate 4 moves down, it drives the gear 6 to rotate synchronously through the connecting rope 10, so that the chain meshing on its outer side rotates to apply paint.

[0039] Regarding the installation design of gear 5, a support plate 11 is fixedly installed on the support frame 2. A guide hole 1101 is opened through the support plate 11. A guide block 12 is slidably installed inside the guide hole 1101. Gear 5 is rotatably installed on one side of the guide block 12. The support plate 11 limits and guides the guide block 12 through the guide hole 1101, so that the guide block 12 can only slide horizontally along the guide hole 1101, thereby ensuring the accurate movement trajectory of gear 5 and ensuring that gear 5 and gear 6 can accurately mesh with the chain, realizing stable support and transmission of the chain. An electric push rod 13 is also fixedly installed on the side wall of the support frame 2. The output end of the electric push rod 13 is fixedly installed with the guide block 12. The electric push rod 13 drives the guide block 12 to move, thereby adjusting the distance between gear 5 and gear 6, adapting to the processing needs of chains of different lengths and pitches, and improving the versatility of the device. At the same time, the chain can be kept at an appropriate tension by adjusting the distance, avoiding uneven painting caused by chain slack.

[0040] Regarding the installation design of gear 26, a connecting plate 14 is fixedly installed on the base 1, and a connecting column 15 is rotatably installed through the connecting plate 14. The connecting plate 14 provides rotational support for the connecting column 15, enabling the connecting column 15 to rotate smoothly. Gear 26 is fixedly installed at the end of the connecting column 15, and a connecting rope 10 is wound around the outside of the connecting column 15. The linear downward movement of the pressure plate 4 is converted into the rotational movement of the connecting column 15 through the connecting rope 10, realizing the synchronous linkage of the "paint supply action" and the "chain drive action", ensuring that the paint supply and the chain rotation rhythm are matched, and ensuring uniform painting. A torsion spring 16 is fixedly installed between the outer surface of the connecting column 15 and the connecting plate 14. After the painting is completed, when the pressure plate 4 is reset, the torsion spring 16 releases elastic potential energy to drive the connecting column 15 to rotate in the opposite direction, causing the connecting rope 10 to be rewound and retracted, helping the pressure plate 4 to quickly reset, and at the same time driving gear 26 to rotate in the opposite direction, which facilitates the unloading or reloading of the chain. This realizes the power transmission of "connecting rope 10 traction → connecting column 15 rotation → gear 26 linkage".

[0041] Regarding the structural design of the air guide frame 8, baffles 17 are symmetrically and rotatably installed at the connection between the air guide frame 8 and the storage box 3. When the two baffles 17 are in a horizontal state, they are sealed and fitted together on opposite sides.

[0042] As a further technical solution, the baffle 17 is rotatably mounted at the connection between the air guide frame 8 and the storage box 3 via a pin, and a coil spring is sleeved on the outer surface of the pin. When there is no external force, the coil spring keeps the baffle 17 in a horizontal state. In the initial state, the baffle 17 maintains a horizontal seal under the action of the coil spring, blocking the connection between the air guide frame 8 and the storage box 3. When the air pressure in the air guide frame 8 reaches a preset value, which is sufficient to push the feeding brush 7 to close and abut, the air pressure overcomes the spring force of the coil spring and causes the baffle 17 to flip downward. The gas enters the storage box 3 and pushes the pressure plate 4 to move downward, realizing the action logic of "closing the brush first and then supplying paint", avoiding premature paint leakage or uneven paint application caused by the feeding brush not being clamped.

[0043] Regarding the installation design of the feeding brush 7, an air supply channel 19 is fixedly installed on the outside of the storage box 3. One side of the air supply channel 19 is connected to the air guide frame 8, and the feeding brush 7 is slidably installed on the other side of the air supply channel 19. The air supply channel 19 is a pressure transmission channel, which guides the air pressure in the air guide frame 8 to the sealing piston 702, and at the same time provides sliding support for the sliding rod 701. A sliding rod 701 is fixedly installed on the side of the feeding brush 7 near the air supply channel 19. The sliding rod 701 passes through and extends into the interior of the air supply channel 19. A sealing piston 702 is fixedly installed at the end of the sliding rod 701. The sealing piston 702 is slidably sealed with the inner surface of the air supply channel 19 to ensure that the air pressure can effectively push the sliding rod 701 to move the feeding brush 7. The sealing design avoids air pressure leakage, ensures stable driving force, and enables the two feeding brushes 7 to move synchronously relative to each other, accurately close and clamp the two sides of the chain.

[0044] Regarding the structural design of the feeding brush 7 and the sliding rod 701, both the feeding brush 7 and the sliding rod 701 have hollow interiors. The end of the sliding rod 701 is connected to the interior of the feeding brush 7, the bottom end of the discharge pipe 9 is connected to the interior of the sliding rod 701, and the bristles on the feeding brush 7 are connected to the interior of the feeding brush 7. The paint enters the interior of the feeding brush 7 through the hollow channel of the sliding rod 701 and then penetrates to the bristles, realizing the method of "internal paint supply + brush bristle application". This ensures that the bristles are always kept moist and the paint is evenly distributed, avoiding uneven painting caused by insufficient paint or paint accumulation in traditional painting.

[0045] As a further technical solution, a transmission rod 20 is rotatably installed inside the storage box 3. The transmission rod 20 passes through the pressure plate 4, and a spiral blade 21 is fixedly installed on the bottom outer surface of the transmission rod 20. A spiral groove 22 is opened on the outer surface of the transmission rod 20. A protrusion 23 is fixedly installed inside the pressure plate 4, extending into the spiral groove 22 and fitting against its inner wall. When the pressure plate 4 moves down, the protrusion 23 inside slides along the spiral groove 22 of the transmission rod 20. Through the guiding effect of the spiral structure, the transmission rod 20 is driven to rotate synchronously. The spiral blade 21 at the bottom of the transmission rod 20 rotates with the transmission rod, stirring the paint at the bottom of the storage box 3, preventing the paint from settling and separating due to prolonged standing, ensuring uniform paint concentration, and thus ensuring consistent paint color and thickness on the chain.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0047] Working principle:

[0048] I. Preprocessing stage:

[0049] The operator attaches the chain to be painted to the outside of gear 5 and gear 6, so that the chain is precisely engaged with the two gears, completing the initial positioning of the chain;

[0050] Start the electric push rod 13. The output end of the electric push rod 13 pushes the guide block 12 to slide horizontally along the guide hole 1101 of the support plate 11, thereby driving gear 5 to move towards gear 6 until the chain is appropriately tensioned. The tension can be adjusted by the stroke of the electric push rod to ensure that the chain does not loosen or deviate during rotation, laying the foundation for uniform painting.

[0051] Sufficient paint is pre-filled into the storage tank 3, and the rubber baffle 18 keeps the cross groove closed without external force to prevent premature paint leakage.

[0052] II. Pneumatic Driven Stage:

[0053] When the external air supply and extraction equipment is started, the gas enters the air guide frame 8 through the air inlet 801, and the air pressure inside the air guide frame 8 gradually increases.

[0054] Gas enters the gas delivery channel 19 through the connection between the gas guide frame 8 and the gas delivery channel 19, and acts on the sealing piston 702. Since the sealing piston 702 is sealed and fitted to the inner wall of the gas delivery channel 19, the thrust generated by the gas pressure pushes the sealing piston 702 to drive the sliding rod 701 to move closer to the chain.

[0055] Two symmetrically arranged feeding brushes 7 move synchronously relative to each other with the sliding rod 701 until the bristles of the two feeding brushes 7 are completely attached to both sides of the chain and clamped. At this time, the feeding brushes 7 stop moving, completing the clamping and positioning of the chain, and avoiding chain displacement during the painting process, which may cause paint leakage or uneven thickness.

[0056] III. Paint Supply Start-up Phase:

[0057] After the feeding brush 7 is clamped, the air pressure in the air delivery channel 19 cannot continue to be released, causing the air pressure in the air guide frame 8 to continue to rise. When the air pressure reaches the preset threshold, the pressure overcomes the elastic force of the coil spring on the pin of the baffle 17, pushing the two horizontally sealed baffles 17 to flip downwards, and the communication channel between the air guide frame 8 and the storage box 3 is opened.

[0058] High-pressure gas enters the upper cavity of the storage box 3, exerting a downward thrust on the pressure plate 4, which pushes the pressure plate 4 to move down at a constant speed along the inner wall of the storage box 3.

[0059] As the pressure plate 4 moves downward, it squeezes the paint in the storage box 3. The pressure of the paint gradually increases, overcoming the elastic resistance of the rubber baffle 18, causing the cross groove on the rubber baffle 18 to open, and the paint enters the discharge pipe 9 through the cross groove.

[0060] IV. Joint Painting Stage:

[0061] The paint in the discharge pipe 9 is transported along the pipe to the hollow channel of the sliding rod 701. Since the feeding brush 7 and the sliding rod 701 are hollow and connected, the paint eventually flows into the interior of the feeding brush 7 and evenly penetrates into the bristles, so that the bristles are always wet and the paint is evenly distributed.

[0062] When the pressure plate 4 moves down, the connecting rope 10 fixed at its bottom is pulled down simultaneously. The connecting rope 10 is wrapped around the outside of the connecting column 15, thereby driving the connecting column 15 to rotate along the connecting plate 14. At this time, the torsion spring 16 is twisted and stores force.

[0063] When the connecting column 15 rotates, the gear 6 fixed at its end rotates synchronously. Since the gear 6 meshes with the chain and the gear 5 provides limiting support for the chain, the rotation of the gear 6 drives the chain to move or rotate at a uniform speed.

[0064] During the movement of the chain, the bristles of the feeding brush 7 are tightly attached to both sides, and the wet bristles evenly apply the paint to the outer surface and gaps of the chain. At the same time, as the pressure plate 4 moves down, the protrusion 23 inside slides along the spiral groove 22 of the transmission rod 20, causing the transmission rod 20 to rotate synchronously. The spiral blade 21 at the bottom of the transmission rod 20 stirs the paint in the storage box 3 to prevent the paint from settling and separating, and to ensure that the paint concentration applied to the chain is consistent.

[0065] V. Chain Replacement Stage:

[0066] When the next chain needs to be painted, the air extraction equipment extracts air. Due to the elastic force of the coil spring on the baffle 17, the air pressure in the air supply channel 19 is released first, thereby driving the sliding rod 701 to move into the air supply channel 19. The two feeding brushes 7 gradually move away. Then, the electric push rod 13 is activated to drive gear 1 5 to move towards gear 2 6, so that the chain is loosened. At this time, the worker can take out the chain and replace it with the next batch of chains to be painted.
