Description

Technical Field

[0001] This utility model relates to the field of feeder technology, and more specifically, to an auxiliary feeder for high-hardness powder coatings. Background Technology

[0002] In the production process of high-hardness powder coatings, because the powder may clump during storage, or other additives need to be added to the powder during reprocessing, the powder is often initially stirred by an auxiliary feeder before being processed, and then conveyed to the processing end by an auger for post-processing.

[0003] However, the existing equipment does not apply the paint evenly and precisely enough, and it is not possible to break up the clumps of paint during application, which leads to a decrease in the quality of the produced paint.

[0004] A search revealed that Chinese patent CN220484436U discloses a powder coating auxiliary feeder. This structure uses a PLC controller to flexibly control the opening and closing of a one-way valve, enabling on-demand coating transfer and resulting in more uniform coating. When it is necessary to crush lumpy particles in the coating, the PLC controller starts the motor, which drives the spiral rotating blade and pulley. Through belt transmission, the motor sequentially drives the second rotating rod, the second bevel gear, the first bevel gear, the first rotating rod, and the cam. The cam squeezes the vibrating screen, and the spring elasticity causes it to vibrate, breaking up the coating lumps. Combined with the cam's tapping action, this improves production efficiency. Simultaneously, the belt rotation mixes and transfers the coating. Furthermore, the controller is detachably connected and fixed to the front end of the feeder, displaying the operating status of the one-way valve. The support rod is attached to the bottom of the feeder for protection. The overall solution has good effects in coating transfer, mixing, crushing, and equipment protection.

[0005] However, in actual use, this structure uses a cam to squeeze the vibrating screen and uses the elasticity of the spring to make it vibrate and break up the paint blocks. Combined with the cam's tapping to improve production efficiency, larger pieces of paint tend to accumulate on the screen, gradually clogging the screen's mesh. This makes it difficult for subsequent paint to pass through the screen smoothly for screening, reducing the overall efficiency of the feeder. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-hardness powder coating auxiliary feeder includes a feeder housing, with multiple support legs fixedly installed on the outside of the feeder housing, a conveying frame passing through the top of the feeder housing, a material leveling frame passing through the top of the conveying frame, and a material leveling mechanism installed inside the material leveling frame.

[0009] The material equalization mechanism includes a first motor fixedly installed on one side of the material equalization frame. A rotating shaft is fixedly installed at the output end of the first motor. Multiple crushing blades are fixedly installed on the outside of the rotating shaft. L-shaped stirring rods are installed on both sides of the crushing blades. Multiple stirring scoops are fixedly installed on the outside of the L-shaped stirring rods.

[0010] The inner wall of the conveying frame is fixedly provided with multiple U-shaped frames, and multiple springs are fixedly provided inside the U-shaped frames. A screening plate is fixedly provided at one end of each spring. One end of the rotating shaft passes through the material distribution frame and is rotatably connected to the inner wall of the material distribution frame. One end of the L-shaped stirring rod is connected to the rotating shaft. The cross-section of the screening plate is set to be arc-shaped.

[0011] By adopting the above technical solutions: the support legs provide stable support for the feeder housing, ensuring stable equipment operation; the crushing blades can crush large pieces of paint; the L-shaped stirring rod and stirring scoop can evenly distribute the paint, improving the quality of paint pretreatment; and the stirring scoop can send the large particles of paint screened out back to the equalization frame for further processing, achieving recycling and reducing waste.

[0012] As a further description of the above technical solution: a small motor is fixedly installed on one side of the conveying frame, a rotating rod is fixedly installed at the output end of the small motor, a cam is fixedly installed at the output end of the rotating rod, a guide groove is opened on the surface of the screening plate, a guide strip is slidably installed inside the guide groove, and the guide strip is fixedly connected to the conveying frame.

[0013] By adopting the above technical solution, the cam squeezes the screening plate, which, in conjunction with the action of the spring, makes the screening plate vibrate up and down, effectively screening the coating, ensuring screening effect and efficiency, providing stable guidance for the vibration of the screening plate, preventing the screening plate from shifting or shaking during vibration, enhancing the stability and reliability of the screening process, and improving the service life and maintenance convenience of the equipment.

[0014] As a further description of the above technical solution: the conveying frame is provided with a flow control mechanism. The control mechanism includes a fixed frame fixedly installed inside the conveying frame. Multiple electric telescopic rods are fixedly installed inside the fixed frame. A limit plate is fixedly installed at the output end of the electric telescopic rod. The limit plate is slidably connected to the fixed frame. An inclined plate is fixedly installed on one side of the limit plate.

[0015] By adopting the above technical solution, the position of the limit plate and the tilting plate can be flexibly adjusted by controlling the extension and retraction of the electric telescopic rod, and the size of the paint channel can be precisely changed to achieve precise control of paint flow rate, meet different production needs, have a high degree of automation, are easy to operate, and the flow rate can be adjusted remotely or automatically through the control system, reducing manual intervention and improving production efficiency.

[0016] As a further description of the above technical solution: a second motor is fixedly installed on one side of the feeder housing, a spiral rotating blade is fixedly provided at the output end of the second motor, a conveying pipe is provided through the bottom of the feeder housing, a sealing cover is hinged to one side of the material equalization frame, and a handle is fixedly provided on the top of the sealing cover.

[0017] By adopting the above technical solution, the second motor drives the spiral rotating blade to rotate, which can efficiently transport the processed coating from the feeder housing to the bottom conveying pipe, ensuring smooth and stable coating conveying and improving the overall feeding efficiency. The conveying pipe at the bottom of the feeder housing provides a clear channel for coating output, which is convenient for connection with subsequent production equipment, enabling the coating to be accurately delivered to the required position and ensuring the continuity of the production process. This not only ensures the coating conveying function, but also takes into account the convenience of operation and the sealing of the equipment, thus enhancing the practicality and reliability of the equipment.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. By setting up a material equalization mechanism, compared with the existing technology, the first motor drives the rotating shaft, which enables the crushing blades to effectively crush the blocky coating. The L-shaped stirring rod and stirring scoop rotate synchronously to mix the coating evenly, laying a good foundation for subsequent screening and conveying. Moreover, the cam squeezes the screening plate to generate vibration to achieve effective screening. Large particles of coating that do not meet the requirements are picked up by the stirring scoop and conveyed upwards, returning to the material equalization frame for crushing and stirring again. This cycle is repeated until the particle size requirements are met, which improves the processing efficiency. Furthermore, by recycling coatings that do not meet the particle size requirements, raw material waste is reduced and production costs are lowered. In addition, the screening plate is fixed by springs and guide bars, ensuring stable movement. The coordinated work of all components ensures the quality of coating processing and improves the overall performance of the equipment.

[0020] 2. By setting up a flow control mechanism, compared with existing technologies, the extension and retraction of the electric telescopic rod in the fixed frame drives the movement of the limit plate and tilting plate, flexibly changing the size of the coating channel and achieving precise control of the coating flow. The conveying volume can be adjusted according to actual production needs, improving the flexibility and adaptability of production. The second motor drives the spiral rotating blade to rotate, which can efficiently push the coating after screening and flow control to the bottom conveying pipe, ensuring the continuity and stability of coating conveying, improving production efficiency, and being suitable for a variety of high-hardness powder coatings with different properties. It can meet the needs of different production scenarios, improve the versatility and practicality of the equipment, and provide convenience for coating processing and application.

[0027] 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.

[0028] The embodiments disclosed in this application are as follows: Figure 1-5The high-hardness powder coating auxiliary feeder shown includes a feeder housing 1, multiple support legs 2 fixedly installed on the outside of the feeder housing 1, a conveying frame 3 through the top of the feeder housing 1, a material leveling frame 4 through the top of the conveying frame 3, and a material leveling mechanism inside the material leveling frame 4.

[0029] The material equalization mechanism includes a first motor 5 fixedly installed on one side of the material equalization frame 4. A rotating shaft 6 is fixedly installed at the output end of the first motor 5. Multiple crushing blades 7 are fixedly installed on the outside of the rotating shaft 6. L-shaped stirring rods 8 are installed on both sides of the crushing blades 7. Multiple stirring spoons 9 are fixedly installed on the outside of the L-shaped stirring rods 8.

[0030] Multiple U-shaped frames 10 are fixedly installed on the inner wall of the conveying frame 3. Multiple springs 11 are fixedly installed inside the U-shaped frames 10. A screening plate 12 is fixedly installed at one end of the spring 11. One end of the rotating shaft 6 passes through the material equalization frame 4 and is rotatably connected to the inner wall of the material equalization frame 4. One end of the L-shaped stirring rod 8 is connected to the rotating shaft 6. The cross-section of the screening plate 12 is set to be arc-shaped.

[0031] Start the first motor 5, which is fixedly installed on one side of the uniform material frame 4. The output end of the first motor 5 drives the rotating shaft 6 to rotate. Since multiple crushing blades 7 are fixedly installed on the outside of the rotating shaft 6, the crushing blades 7 rotate along with the rotating shaft 6, crushing the larger pieces of paint that enter the uniform material frame 4, so that the particle size becomes smaller.

[0032] At the same time, the L-shaped stirring rod 8 fixed on the rotating shaft 6 also rotates. The multiple stirring spoons 9 on the outside of the L-shaped stirring rod 8 stir the coating, making the coating more evenly distributed in the uniform material frame 4, in preparation for subsequent screening and conveying.

[0033] Vibration causes the coating to be screened on the screening plate 12. Coating that meets the particle size requirements continues to be conveyed downward through the screening plate 12, while large particles of coating that do not meet the requirements remain on the screening plate 12. When the stirring spoon 9 passes above the screening plate 12, it uses its own shape and movement trajectory to scoop up the large particles of coating that remain on the screening plate 12. As the L-shaped stirring rod 8 rotates, it will carry the large particles of coating upward. During the upward movement, the large particles of coating will leave the surface of the screening plate 12 and be conveyed to a higher position in the uniform material frame 4. There, they will be crushed again by the crushing action of the crushing blade 7 and stirred by the stirring spoon 9, which will further reduce their particle size. The stirring spoon 9 will continue to stir, making the coating more uniform. After such repeated processing, the large particles of coating can finally reach the required particle size and enter the subsequent conveying process through the screening plate 12.

[0034] The large particles of paint remaining on the sieve plate 12 are conveyed upward by the stirring scoop 9 and processed again, realizing the recycling of paint that does not meet the particle size requirements, improving the processing efficiency and quality of paint, and reducing the waste of raw materials.

[0035] Reference Figure 2-3 As shown, a small motor 13 is fixedly installed on one side of the conveyor frame 3. A rotating rod 14 is fixedly installed at the output end of the small motor 13. A cam 15 is fixedly installed at the output end of the rotating rod 14. A guide groove is opened on the surface of the screening plate 12. A guide bar 16 is slidably installed inside the guide groove. The guide bar 16 is fixedly connected to the conveyor frame 3.

[0036] After being homogenized and crushed, the coating material enters the conveying frame 3 from the homogenizing frame 4. The small motor 13 on one side of the conveying frame 3 is started. The small motor 13 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the cam 15 to rotate.

[0037] As the cam 15 rotates, it continuously squeezes the screening plate 12. Since the screening plate 12 is fixed in the U-shaped frame 10 by the spring 11, and the guide strip 16 in the guide groove on the surface of the screening plate 12 is fixedly connected to the conveying frame 3, the screening plate 12 moves up and down reciprocally under the squeezing of the cam 15 and the elastic action of the spring 11.

[0038] Reference Figure 4-5 As shown, the conveying frame 3 is equipped with a flow control mechanism. The control mechanism includes a fixed frame 17 fixedly installed inside the conveying frame 3. Multiple electric telescopic rods 18 are fixedly installed inside the fixed frame 17. A limit plate 19 is fixedly installed at the output end of the electric telescopic rod 18. The limit plate 19 is slidably connected to the fixed frame 17. An inclined plate 20 is fixedly installed on one side of the limit plate 19.

[0039] By controlling the extension and retraction of multiple electric telescopic rods 18 within the fixed frame 17, the output end of the electric telescopic rods 18 drives the limiting plate 19 to slide within the fixed frame 17. The inclined plate 20 on one side of the limiting plate 19 moves with the limiting plate 19, changing the size of the channel through which the paint passes, thereby achieving control of the paint flow rate.

[0040] Reference Figure 1 , 5 As shown, a second motor 21 is fixedly installed on one side of the feeder housing 1, and a spiral rotating blade 22 is fixedly installed at the output end of the second motor 21. A conveying pipe 23 is provided through the bottom of the feeder housing 1. A sealing cover 24 is hinged to one side of the material equalization frame 4, and a handle 25 is fixedly installed on the top of the sealing cover 24.

[0041] The operator opens the hinged sealing cover 24 on one side of the uniform material frame 4 through the handle 25, pours the high-hardness powder coating into the uniform material frame 4, and then closes the sealing cover 24 to prevent the coating from overflowing during subsequent processing.

[0042] Start the second motor 21 on one side of the feeder housing 1. The second motor 21 drives the spiral rotating blade 22 to rotate. The coating material after screening and flow control enters the feeder housing 1. The spiral rotating blade 22 rotates and conveys the coating material to the bottom conveying pipe 23. Finally, the coating material is conveyed to the place where it is needed through the conveying pipe 23.

[0043] Working principle of this utility model:

[0044] This utility model is an auxiliary feeder for high hardness powder coating. When using the device, the operator opens the sealing cover 24 hinged on one side of the uniform material frame 4 through the handle 25, pours the high hardness powder coating into the uniform material frame 4, and then closes the sealing cover 24 to prevent the coating from overflowing during subsequent processing.

[0045] At the same time, the first motor 5, which is fixedly installed on one side of the uniform material frame 4, is started. The output end of the first motor 5 drives the rotating shaft 6 to rotate. Since multiple crushing blades 7 are fixedly installed on the outside of the rotating shaft 6, the crushing blades 7 rotate along with the rotating shaft 6, crushing the larger pieces of paint that enter the uniform material frame 4, so that the particle size becomes smaller.

[0046] At the same time, the L-shaped stirring rod 8 fixed on the rotating shaft 6 also rotates. The multiple stirring spoons 9 on the outside of the L-shaped stirring rod 8 stir the coating, making the coating more evenly distributed in the uniform material frame 4, in preparation for subsequent screening and conveying.

[0047] After being homogenized and crushed, the coating material enters the conveying frame 3 from the homogenizing frame 4. The small motor 13 on one side of the conveying frame 3 is started. The small motor 13 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the cam 15 to rotate.

[0048] As the cam 15 rotates, it continuously squeezes the screening plate 12. Since the screening plate 12 is fixed in the U-shaped frame 10 by the spring 11, and the guide strip 16 in the guide groove on the surface of the screening plate 12 is fixedly connected to the conveying frame 3, the screening plate 12 moves up and down reciprocally under the squeezing of the cam 15 and the elastic action of the spring 11.

[0049] This vibration causes the coating to be screened on the screening plate 12. Coating that meets the particle size requirements continues to be conveyed downward through the screening plate 12, while large particles of coating that do not meet the requirements remain on the screening plate 12. When the stirring spoon 9 passes above the screening plate 12, it uses its own shape and movement trajectory to scoop up the large particles of coating that remain on the screening plate 12. As the L-shaped stirring rod 8 rotates, it will carry the large particles of coating upward. During the upward movement, the large particles of coating will leave the surface of the screening plate 12 and be conveyed to a higher position in the uniform material frame 4. There, they will be crushed again by the crushing action of the crushing blade 7 and stirred by the stirring spoon 9, which will further reduce their particle size. The stirring spoon 9 will continue to stir, making the coating more uniform. After such repeated processing, the large particles of coating can finally reach the required particle size and enter the subsequent conveying process through the screening plate 12.

[0050] The large particles of paint remaining on the sieve plate 12 are conveyed upward by the stirring spoon 9 and processed again, realizing the recycling of paint that does not meet the particle size requirements, improving the processing efficiency and quality of paint, and reducing the waste of raw materials.

[0051] Next, by controlling the extension and retraction of multiple electric telescopic rods 18 within the fixed frame 17, the output end of the electric telescopic rods 18 drives the limiting plate 19 to slide within the fixed frame 17. The inclined plate 20 on one side of the limiting plate 19 moves with the limiting plate 19, changing the size of the channel through which the paint passes, thereby achieving control of the paint flow rate.

[0052] Then, the second motor 21 on one side of the feeder housing 1 is started. The second motor 21 drives the spiral rotating blade 22 to rotate. After screening and flow control, the paint enters the feeder housing 1. The spiral rotating blade 22 rotates and conveys the paint to the bottom conveying pipe 23. Finally, the paint is conveyed to the place where it is needed through the conveying pipe 23.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
