Description

Technical Field

[0001] This invention relates to the field of roller coating machines, and more specifically, to a coating material tray. Background Technology

[0002] In the field of coating application, the paint tray, as a core auxiliary tool for carrying paint and working with paint rollers for coating operations, is widely used in various scenarios such as building decoration, furniture manufacturing, and industrial equipment coating. Its main function is to provide a stable supply of paint to the paint rollers, ensuring that the paint rollers can evenly form a coating on the surface of the material to be coated after being dipped in paint. Therefore, the rationality of the tray's structure and its performance directly affect the efficiency of coating application and the quality of the coating. However, the mainstream traditional paint trays currently on the market generally suffer from the problem of air bubbles that are difficult to solve in actual applications. This problem has become a key bottleneck restricting the improvement of coating construction quality. Specifically, when the paint roller rolls and picks up paint in the paint tray, the rotation of the paint roller will have a significant driving effect on the paint inside the tray, causing the paint to flow rapidly within the tray cavity. Since the paint itself has a certain viscosity, there will be a violent impact and friction between the paint and the inner wall of the tray during the flow process. This impact can easily disrupt the stable state inside the paint, causing air to be drawn into the paint, and thus forming a large number of air bubbles inside the paint and at the interface where the paint contacts the inner wall. At the same time, during the process of the paint roller contacting and rolling with the paint, the relative movement between the fiber or sponge structure on its surface and the paint will further aggravate the generation of bubbles; the pores on the surface of the paint roller will adsorb some air when rolling. When these pores come into contact with the paint, the air is difficult to expel quickly and will remain in the paint in the form of bubbles or adhere to the surface of the paint roller. More importantly, traditional paint trays only have a single function of carrying paint and lack the structural design and functional modules to actively remove air bubbles from the paint. Once air bubbles are formed, they cannot be automatically broken or discharged by the tray's own structure, nor can they be eliminated by the normal rolling motion of the paint roller. These residual air bubbles adhere to the surface of the paint roller as it picks up the paint. When the paint roller applies the coating material, the air bubbles are transferred to the coating layer, ultimately causing defects such as pinholes, bulges, and sagging on the surface of the coating material. In addition, the presence of air bubbles also damages the uniformity of the coating, reduces the coating's adhesion, wear resistance, and corrosion resistance, seriously affects the appearance quality and service life of the coated product, increases the cost and workload of subsequent repair work, and causes great inconvenience to actual construction.

[0003] In summary, traditional paint trays cannot solve the problem of air bubbles generated during paint roller operation, making it difficult to meet the demands of modern paint application for high quality and high efficiency. There is an urgent need for a new type of paint tray that can actively remove air bubbles from the paint and ensure coating quality to overcome the above-mentioned defects. Summary of the Invention

The return pipes are located above the filter plate, and the first pipes are located below the filter plate.

[0009] Furthermore, a flow-enhancing component for improving the reflux effect is installed on the side of the container away from the second pipe. The flow-enhancing component includes multiple evenly distributed second floats, which are fixedly connected by lightweight connecting rods. Multiple evenly distributed telescopic connecting rods are fixedly installed on the lightweight connecting rods. The telescopic connecting rods are fixedly installed on the container. An energy storage mechanism is provided below one of the middle second floats, and an energy supply mechanism is provided on one side of the energy storage mechanism.

[0010] Furthermore, the energy storage mechanism includes an energy storage sleeve, which is fixedly installed on the inner side surface of the mounting plate. Both sides of the energy storage sleeve are provided with fan brackets, which are also fixedly installed on the inner side surface of the mounting plate.

[0011] Furthermore, the power supply mechanism includes a first slide rod, a ratchet is provided on one side of the lower end of the first slide rod, the ratchet is fixedly mounted on the transmission link, one end of the coil spring is fixedly mounted on the ratchet, a rotating sleeve is provided above the ratchet, a second ratchet tooth is slidably engaged inside the rotating sleeve, a spring is fixedly connected between the rotating sleeve and the second ratchet tooth, a plurality of evenly distributed first spring telescopic rods are slidably mounted on the side of the first slide rod away from the ratchet, the first spring telescopic rods are fixedly mounted on the inner wall of the receiving plate, a second fixed sleeve is fixedly connected to the telescopic end of the first spring telescopic rod through a bracket, rotating brackets are rotatably mounted on both sides of the rotating sleeve, the rotating brackets are fixedly mounted on the inner wall of the receiving plate, and a baffle is provided on the side of the second fixed sleeve near the first slide rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This solution, by setting up blocking and reflux components, can drive the liquid to reflux and absorb air bubbles, preventing air bubbles from remaining on the liquid surface and sticking to the paint roller, thus achieving efficient and rapid air bubble removal.

[0015] 2. This solution, by setting up a reflux component, can use the surface tension of the liquid to absorb air bubbles on the coating surface when the first float is driven up by the waves, which further increases the efficiency of air bubble removal. Moreover, no external equipment is required; the removal work can be carried out by the ripples generated by the rotation of the coating roller itself.

[0016] 3. This solution uses an outer reflux cylinder and an inner reflux cylinder. When the first float descends, it will cause the first reflux port to open and suck up the bottom layer of the coating, absorbing some sediments and residues. As the first float rises again, the liquid sucked up by the first reflux port will descend and generate negative pressure, increasing the suction at the second reflux port, thereby further increasing the efficiency of bubble absorption.

[0017] 4. This solution, by setting up a flow-enhancing component, allows the second float to rise and fall continuously as the waves drive it, absorbing the kinetic energy brought by the waves and converting it into the kinetic energy of the fan blades. This increases the fluidity of the liquid generated by the rotation of the paint roller, making its flow to the return components on both sides more efficient. The increased fluid flow efficiency allows air bubbles to flow quickly and not remain on the liquid surface, thus preventing them from sticking to the paint roller. Even if air bubbles do appear, the occurrence of them sticking to the surface of the paint roller will be reduced. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 10A paint container tray includes a fixed support 1, on which a return bucket 2 for collecting foam is fixedly installed. A container tray 3 for holding paint is fixedly installed at the upper end of the fixed support 1. The four corners of the container tray 3 are rounded. Return components 5 for foam return are installed on both sides of the inside of the container tray 3. Two blocking components 4 are provided inside the container tray 3 at positions corresponding to the return components 5. A flow booster component 6 for enhancing the return effect is installed on the side of the inside of the container tray 3 away from the second pipe. The flow booster component 6 includes multiple evenly distributed second floats 61. The multiple second floats 61 are fixedly connected to each other by lightweight connecting rods 611. Multiple evenly distributed telescopic connecting rods 612 are fixedly installed on the lightweight connecting rods 611. The telescopic connecting rods 612 are fixedly installed on the container tray 3. An energy storage mechanism 62 is provided below the middle second float 61. An energy supply mechanism 63 is provided on one side of the energy storage mechanism 62.

[0022] In actual use, first inject paint into the receiving tray 3 until the paint level is flush with the return component 5. Fill the return bucket 2 with paint. Then, slowly place the paint roller into the receiving tray 3, immersing the lower half of the roller in the paint. Then, use an external device to drive the paint roller to rotate. At this time, the paint roller will pick up paint from the receiving tray 3 and coat the material surface. When the paint roller rotates, the paint inside the receiving tray 3 will be carried along... Figure 10 The paint flows in a cyclical manner as shown. Because the paint roller rotates continuously, the paint on one side of the paint roller is continuously driven to move to the other side, which results in the liquid level on one side of the paint roller being lower than the liquid level on the other side. As the paint is driven by the paint roller to impact the inner wall of the receiving tray 3, a large amount of foam is easily generated. If this foam is not dealt with, it will stick to the paint roller and be driven to the material surface, which will result in many defects in the material surface due to incomplete coating. As the coating roller rotates and drives the coating to flow inside the container 3, the foam generated on the surface of the coating is pushed to the inner wall of the container 3 by the flowing liquid. As the coating continues to flow, the bubbles are blocked by the blocking component 4 and no longer flow to the side with a higher coating level, ensuring that no bubbles flow back to the side with a lower coating level. When the coating roller rotates, it continuously drives the coating to impact the inner wall of the container 3, which causes waves to be generated near the inner wall of the container 3. The wave intensity is higher near the inner wall than far from the inner wall of the container 3 due to the interference of the waves. When the coating roller rotates, it drives the return component 5 to work to collect the bubbles around the blocking component 4 and carry the bubbles into the return tank 2. The bubbles are eliminated inside the return tank 2 to avoid affecting the material. The rounded corners of the container 3 facilitate the flow of the coating and allow the bubbles to be blocked by the blocking component 4 and removed by the return component 5, preventing too many bubbles from remaining on the liquid surface and affecting the coating.

[0023] The reflux component 5 includes a first fixed sleeve 51, which is fixedly mounted on the receiving plate 3. A reflux inner cylinder 52 is fixedly mounted at the center of the first fixed sleeve 51. A reflux outer cylinder 53 is slidably fitted around the outside of the reflux inner cylinder 52. A first reflux port 521 is opened at the lower end of the reflux inner cylinder 52, and a second reflux port 522 is opened at the upper end of the reflux inner cylinder 52. A rotating ring 54 is rotatably fitted around the outside of the reflux outer cylinder 53. A matching slide rod 541 is fixedly mounted on one side of the rotating ring 54. A first float 55 is provided on one side of the reflux outer cylinder 53. A first hinge block 551 is provided between the first float 55 and the first fixed sleeve 51. The first hinge block 551 is fixedly mounted on the receiving plate 3, and a first float 55 is fixedly mounted on the first float 55. A V-shaped connecting rod 552 is rotatably mounted on a first hinge block 551 at its middle part. A second hinge block 553 is rotatably mounted on the end of the V-shaped connecting rod 552 away from the first float 55. The second hinge block 553 is sleeved on the outside of the sliding rod 541. The blocking component 4 includes a first mesh plate 41. A slide rail 411 is fixedly mounted on the bottom end of the first mesh plate 41. Both the slide rail 411 and the first mesh plate 41 are fixedly mounted on the receiving plate 3. A second mesh plate 42 is slidably mounted on one side of the first mesh plate 41. The second mesh plate 42 is slidably locked inside the slide rail 411. An inclined slider 421 is fixedly mounted on the top end of the second mesh plate 42. A spring 422 is fixedly connected between the second mesh plate 42 and the receiving plate 3.

[0024] When the paint roller descends, it first contacts the inclined slider 421. The inclined slider 421 is inclined, so it will move to both sides under the downward pressure of the paint roller. Finally, the second mesh plate 42 is in contact with both sides of the paint roller. The spring 422 can ensure that the second mesh plate 42 is in close contact with the paint roller. Since the paint roller and the blocking component 4 are both immersed in the paint, the liquid paint can play a lubricating role, reducing the friction between the second mesh plate 42 and the paint roller. In addition, the second mesh plate 42 and the first mesh plate 41 can also block air bubbles in the paint flow process.

[0025] When waves are generated, the waves will first push the first float 55 to rise to the crest position. When the first float 55 rises, it will drive the V-shaped connecting rod 552 to rotate around the first hinge block 551. At this time, the second hinge block 553 will slide along the matching slide rod 541 and the rotating ring 54 will be driven down by the V-shaped connecting rod 552. At this time, the return outer cylinder 53 will be driven down as well. Because the buoyancy of the return outer cylinder 53 is small, it will be pressed below the paint liquid surface. At this time, the second return port 522 will be exposed. Then the paint will quickly flow into the interior of the return inner cylinder 52 through the second return port 522. At this time, the first return port 521 is blocked. The air bubbles blocked at the position of the blocking component 4 will be carried by the fast-flowing paint through the second return port 522 into the interior of the return inner cylinder 52, and finally enter the interior of the return tank 2 through the return pipe 31. When the first float 55 is at the trough of the wave, due to surface tension, the first float 55 will be drawn down and descend along with the liquid. Its own weight will also cause it to fall. As the first float 55 descends from its initial position, the end of the V-shaped connecting rod 552 furthest from the first float 55 will rise. The V-shaped connecting rod 552 will then drive the sliding rod 541 and the rotating ring 54 to rise. The rotating ring 54 will then drive the return outer cylinder 53 to rise, exposing the first return port 521, which is located at the bottom of the inner part of the receiving plate 3. When 521 is opened, it can suck up some solid sediments deposited at the bottom of the container 3 and transport them to the inside of the return tank 2 through the first return port 521, the return inner cylinder 52, and the return pipe 31. The filter plate 21 can filter and separate the sediments and residues. The length of the first float 55 from the first hinge block 551 is greater than the length of the first hinge block 551 from the matching slide bar 541. By using the lever principle, the force generated by the first float 55 being driven by the waves can be smaller or amplified by the lever to drive the matching slide bar 541 to rise and fall. After the first return port 521 sucks up the bottom layer of the coating, the first float 55 is pushed to the crest of the wave again. At this time, the first fixed sleeve 51 descends again to block the first return port 521, and the second return port 522 leaks out. The coating that the first return port 521 just sucked up will continue to fall along the return pipe 31 under the action of gravity. The falling coating will cause a negative pressure to be generated inside the return pipe 31. The second return port 522 will generate suction due to the negative pressure. The second return port 522 can further suck up the air bubbles and the surface of the coating, further improving the efficiency of air bubble return.

[0026] A filter plate 21 is fixedly installed inside the return material bin 2. Two return pipes 31 corresponding to the return component 5 are fixedly installed on the lower surface of the receiving tray 3. The return pipes 31 are connected to the interior of the corresponding first fixed sleeve 51. A return pump 11 is fixedly installed on the fixed bracket 1. The input end of the return pump 11 is connected to the bottom of the return material bin 2 through the first pipe. The output end of the return pump 11 is connected to the interior of the receiving tray 3 through the second pipe. The return pipe 31 is located above the filter plate 21, and the first pipe is located below the filter plate 21.

[0027] When the reflux component 5 is working, a portion of the paint containing air bubbles is returned to the inside of the return tank 2 through the receiving tray 3. The filter plate 21 blocks the air bubbles above the filter plate 21, while the paint passes through the filter plate 21 and enters the bottom of the return tank 2. After losing the support of the liquid, the air bubbles will quickly burst. Then, the reflux pump 11 draws clean paint from the bottom of the return tank 2 through the first pipe and returns it to the side with the lower liquid level inside the receiving tray 3 through the second pipe. This can prevent insufficient paint and incomplete coating during continuous coating, and eliminate the generated air bubbles, turning them back into liquid paint for reuse, thus reducing paint loss.

[0028] The energy storage mechanism 62 includes an energy storage sleeve 621, which is fixedly installed on the inner side surface of the mounting plate 3. Fan brackets 622 are provided on both sides of the energy storage sleeve 621, and are also fixedly installed on the inner side surface of the mounting plate 3. Fan blades 623 are rotatably mounted inside the fan brackets 622. A transmission link 624 is fixedly connected between the two fan blades 623. The transmission link 624 is rotatably mounted in the middle of the energy storage sleeve 621. Coil springs 625 are provided on both sides of the energy storage sleeve 621, with one end of each coil spring fixedly installed on the energy storage sleeve 621. The energy supply mechanism 63 includes a first slide rod 631, with a second slide rod 636 slidably mounted inside the first slide rod 631. A ratchet 632 is provided on one side of the lower end of the first slide rod 631, and is fixedly installed on the transmission link 624. One end of each coil spring 625 is fixedly installed on the ratchet. On 632, a rotating sleeve 633 is provided above the ratchet 632. The rotating sleeve 633 has a second ratchet 6331 slidingly engaged inside. A spring is fixedly connected between the rotating sleeve 633 and the second ratchet 6331. Multiple evenly distributed first spring telescopic rods 635 are slidably installed on the side of the first slide rod 631 away from the ratchet 632. The first spring telescopic rods 635 are fixedly installed on the inner wall of the receiving plate 3. A second fixed sleeve 634 is fixedly connected to the telescopic end of the first spring telescopic rod 635 through a bracket. Rotating brackets 6332 are rotatably installed on both sides of the rotating sleeve 633. The rotating brackets 6332 are fixedly installed on the inner wall of the receiving plate 3. The side of the second fixed sleeve 634 near the first slide rod 631 has a baffle 6341. Multiple evenly distributed first ratchet teeth 6311 are fixedly installed at the lower end of the side of the first slide rod 631 near the ratchet 632.

[0029] When the liquid flows, a large wave will first be generated at the position of the second float 61. The second float 61 will also be driven up and down by the wave. When the second float 61 and the lightweight connecting rod 611 rise, they will drive the second slide rod 636 and the first slide rod 631 to rise synchronously. At this time, the first ratchet 6311 will cooperate with the ratchet 632 to drive the ratchet 632 to rotate. The second ratchet 6331 will be pushed into the interior of the rotating sleeve 633 by the ratchet 632. During descent, the first ratchet 6311 will not drive the ratchet 632 to rotate. The ratchet 632 is stuck by the second ratchet 6331 and cannot rotate. When the ratchet 632 is driven to rotate, it will drive the coil spring 625 to compress. After the second slide bar 636 rises and falls a certain number of times, the coil spring 625 is compressed to its maximum state and cannot be compressed further. At this time, when the second float 61 and the lightweight connecting rod 611 are driven to rise again by the waves, the second slide bar 636 will be blocked by the lightweight connecting rod 611. The first slide rod 631 is disengaged from its interior and held in place by the first ratchet 6311 and ratchet 632. When the second slide rod 636 rises, it causes the first slide rod 631 to move away from the ratchet 632, thereby compressing the first spring telescopic rod 635. The first ratchet 6311 and ratchet 632 become ineffective. When the first spring telescopic rod 635 is compressed, it causes the second fixed sleeve 634 and baffle 6341 to move away from the rotating sleeve 633. At this time, the rotation... The sleeve 633 can rotate around the rotating bracket 6332. At this time, the ratchet 632 loses all its locking function and rotates rapidly under the action of the coil spring 625. The ratchet 632 will drive the transmission link 624 and the fan blade 623 to rotate rapidly. The rotation of the fan blade 623 can push the paint, further increasing the flow of the paint and increasing the flow rate of the paint to both sides. This can drive the air bubbles to move quickly to both sides of the receiving plate 3, preventing them from sticking to the surface of the paint roller and further increasing the air bubble removal rate.

[0030] A plurality of evenly distributed push blocks 6361 are fixedly installed on one side of the second slide rod 636. The interior of the first slide rod 631 is provided with a plurality of second slots 6313 corresponding to the push blocks 6361. The second slide rod 636 is provided with a plurality of evenly distributed sliding grooves 6362. Two symmetrical spherical protrusions 6363 are slidably engaged inside the sliding grooves 6362. A spring 6364 is fixedly connected between the two spherical protrusions 6363. The second slide rod 636 is fixedly installed on the lightweight connecting rod 611. The upper interior of the first slide rod 631 is provided with a plurality of evenly distributed first slots 6312 at the position corresponding to the spherical protrusions 6363.

[0031] When the coil spring 625 is compressed to its maximum state, the first slide rod 631 cannot rise. Under the action of tension, the spherical protrusion 6363 of the second slide rod 636 compresses the spring 6364 from the inside of the first slot 6312 into the inside of the sliding groove 6362, losing its engagement with the first slot 6312. Furthermore, the rise of the second slide rod 636 can also cause the push block 6361 to disengage from the inside of the second slot 6313. In turn, the push block 6361 will push the first slide rod 631 to move, thereby limiting the force. When the coil spring 625 releases its force and returns to its initial state, the second float 61 and the lightweight connecting rod 611 descend, which will cause the second slide rod 636 to lock the first slide rod 631 again. The first spring telescopic rod 635 pushes the second fixed sleeve 634 and the baffle 6341 again to stop the rotating sleeve 633 from rotating, making it easy to use continuously.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
