Description

Technical Field

[0001] This utility model relates to the field of powder coating machine technology, and in particular to a double-layer vibrating screen uniform powder coating mechanism and a powder coating machine. Background Technology

[0002] In food processing, coating is a common step. By coating the surface of materials with a layer of powder, the taste, color, and texture of the materials can be improved. However, excess powder often remains on the surface of the materials after coating. If it is not filtered out in time, it will not only affect the quality of the product but also result in the waste of the powder.

[0003] Currently, there are some devices on the market for filtering out excess powder from the surface of materials, but most of these devices have the following problems: First, the screening effect is not ideal, and it is impossible to effectively separate powders of different particle sizes, resulting in inconsistent quality of the recovered powder; second, the powder recovery efficiency is low, and it is impossible to realize the recycling of powder, which increases production costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as unsatisfactory screening effects, inability to effectively separate powders of different particle sizes, and inconsistent quality of recovered powders. The invention proposes a double-layer vibrating screen uniform powder feeding mechanism and a powder coating machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-layer vibrating screen uniform powder feeding mechanism and powder coating machine includes a machine body, a turntable is rotatably provided at the top of the machine body, two support frames are fixed at the top of the machine body, an installation frame is fixed between the two support frames, and a grid conveyor belt for conveying materials is provided inside the installation frame;

[0007] To remove excess powder from the material surface, a fixing plate is fixed to the top of the machine body. A U-shaped frame is fixed to the top of the fixing plate, and a material box is fixed to the top of the U-shaped frame. A circular frame for accommodating the material slides inside the material box. The circular frame is located below the grid conveyor belt. A first screen and a second screen for screening the material are fixed inside the circular frame. The first screen is located above the second screen, and the filtration radius of the first screen is larger than that of the second screen. A set of reciprocating components is provided inside the material box to drive the first screen and the second screen for screening.

[0008] To facilitate the return of the filtered powder to the turntable, a set of conveying components is installed inside the U-shaped frame;

[0009] And a synchronization component used in conjunction with the conveying component, the synchronization component being located between the material box and the U-shaped frame to drive the reciprocating component to move when the conveying component is started.

[0010] In one possible design, the conveying assembly includes a first rotating shaft and a second rotating shaft rotating within a U-shaped frame. Conveyor rollers are fixed to the surfaces of both the first and second rotating shafts, and a conveyor belt is drivingly connected to the surfaces of the two conveyor rollers. A third rotating shaft is fixed to the side end of the U-shaped frame and is fixedly connected to the first rotating shaft via a coupling. The conveyor belt is located below the second screen. A drive motor is fixed to the U-shaped frame and is fixedly connected to the first rotating shaft via a coupling.

[0011] The process involves starting a drive motor to rotate a third shaft, which in turn rotates a conveyor roller. The conveyor roller then drives a conveyor belt to transport the powder that has been sieved through the first and second screens onto the conveyor belt. The powder is then transported by the conveyor belt to a turntable for recycling.

[0012] In one possible design, the reciprocating assembly includes a first groove formed in the material box, a sliding plate sliding in the first groove, the sliding plate being fixed to the side end of the U-shaped frame, a groove formed in the sliding plate, a slider sliding in the groove, a third rotating shaft rotating in the first groove, a rotating rod fixed to the surface of the third rotating shaft, and the slider being fixed to the side end of the rotating rod.

[0013] The third rotating shaft rotates, which in turn drives the rotating rod to rotate. The rotating rod drives the slider to perform circular motion. When the slider moves in a circular motion, it drives the slide plate to perform reciprocating linear motion. The slide plate drives the return frame, the first screen and the second screen to perform reciprocating screening in the material box, and screens the powder onto the conveyor belt.

[0014] In one possible design, the synchronization assembly includes a timing belt, the side end of the first rotating shaft extends outward through the side end of the U-shaped frame, the side end of the third rotating shaft extends outward through the side end of the material box, a small timing pulley is fixed to the surface of the third rotating shaft, a large timing pulley is fixed to the surface of the first rotating shaft, and the timing belt drive is connected to the surfaces of the large timing pulley and the small timing pulley.

[0015] The first rotating shaft drives the large synchronous wheel to rotate, which in turn drives the small synchronous wheel to rotate via a conveyor belt. The small synchronous wheel can then drive the third rotating shaft to rotate.

[0016] In one possible design, two connecting rods are fixed inside the material box, and both connecting rods move outward through the U-shaped frame. The side ends of the two connecting rods are fixed with the same push plate.

[0017] The push plate is fixedly installed inside the U-shaped frame. When the first screen moves back and forth, the material on the first screen is pushed outward by the push plate, making it easy to remove the material.

[0018] In this application, the start-up drive motor drives the third rotating shaft to rotate, the third rotating shaft drives the conveyor roller to rotate, the conveyor roller drives the conveyor belt to transport, and the powder screened by the first screen and the second screen falls onto the conveyor belt and is transported by the conveyor belt to the turntable for recycling.

[0019] By driving the third rotating shaft to rotate, the third rotating shaft drives the rotating rod to rotate, and the rotating rod drives the slider to perform circular motion. When the slider moves in a circular motion, it drives the slide plate to perform reciprocating linear motion. The slide plate drives the return frame, the first screen and the second screen to perform reciprocating screening in the material box, and screens the powder onto the conveyor belt.

[0020] The first shaft drives the large synchronous pulley to rotate, which in turn drives the small synchronous pulley to rotate via a conveyor belt. The small synchronous pulley can then drive the third shaft to rotate.

[0021] Beneficial effects: In this utility model, the double-layer vibrating screen uniform powder feeding mechanism and powder coating machine, by setting a first screen and a second screen, and the filtration radius of the first screen is larger than that of the second screen, can realize the classification and screening of excess powder on the surface of the material, effectively separate powder of different particle sizes, and improve the quality of recycled powder.

[0022] In this invention, the double-layer vibrating screen uniform powder feeding mechanism and powder coating machine, by setting a conveying component, can promptly send the screened powder back to the turntable for recycling, thereby improving the powder recycling efficiency and reducing production costs.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1: Refer to Figures 1-4 This invention relates to a double-layer vibrating screen uniform powder-dispensing mechanism and a powder-coating machine, which falls within the field of powder-coating machine technology. The mechanism includes a machine body 1, with a turntable 2 rotatably mounted on its top. Two support frames 5 are fixed to the top of the machine body 1, and a mounting frame 3 is fixed between the two support frames 5. The mounting frame 3 contains a grid conveyor belt 4 for conveying materials. Materials are placed on the grid conveyor belt 4, and the rotation of the grid conveyor belt 4 transports the materials to a designated location.

[0030] To remove excess powder from the material surface, a fixing plate 6 is fixed to the top of the machine body 1. A U-shaped frame 7 is fixed to the top of the fixing plate 6, and a material box 9 is fixed to the top of the U-shaped frame 7. A circular frame 10 for holding the material is slidably installed inside the material box 9. The circular frame 10 is located below the grid conveyor belt 4. A first screen 11 and a second screen 12 for screening the material are fixed inside the circular frame 10. The first screen 11 is located above the second screen 12, and the filtration radius of the first screen 11 is larger than that of the second screen 12. When the material falls from the grid conveyor belt 4, it first passes through the first screen 11. Larger particle sizes are trapped on the first screen 11, while smaller particle sizes fall through the first screen 11 into the second screen 12, further achieving the grading and screening of the powder.

[0031] The material box 9 is equipped with a reciprocating assembly, which drives the first screen 11 and the second screen 12 to perform screening. The reciprocating assembly includes a first groove 19 formed in the material box 9, a slide plate 21 sliding in the first groove 19, the slide plate 21 being fixed to the side end of the U-shaped frame 10, a groove 22 formed in the slide plate 21, and a slider 23 sliding in the groove 22. A third rotating shaft 15 rotates in the first groove 19, and a rotating rod 20 is fixed to the surface of the third rotating shaft 15. The slider 23 is fixed to the side end of the rotating rod 20. By driving the third rotating shaft 15 to rotate, the third rotating shaft 15 drives the rotating rod 20 to rotate, and the rotating rod 20 drives the slider 23 to perform circular motion. When the slider 23 moves in a circular motion, it drives the slide plate 21 to perform reciprocating linear motion. The slide plate 21 drives the U-shaped frame 10, the first screen 11, and the second screen 12 to perform reciprocating screening in the material box 9, thereby improving screening efficiency.

[0032] To facilitate the return of filtered powder to the turntable 2, a conveying assembly is installed within the U-shaped frame 7. The conveying assembly includes a first rotating shaft 14 and a second rotating shaft 141 rotating within the U-shaped frame 7. Conveyor rollers 13 are fixed to the surfaces of both shafts 14 and 141, and a conveyor belt 8 is connected to the surfaces of the two conveyor rollers 13. The conveyor belt 8 is located below the second screen 12. A drive motor 26 is fixed to the U-shaped frame 7 and is fixedly connected to the first rotating shaft 14 via a coupling. Starting the drive motor 26 drives the third rotating shaft 15 to rotate, which in turn drives the conveyor rollers 13 to rotate. The conveyor rollers 13 then drive the conveyor belt 8 to transport the powder that has passed through the first and second screens 11 onto the conveyor belt 8, where it is then conveyed to the turntable 2 for recycling.

[0033] To achieve linkage between the conveying and reciprocating components, a synchronization component is provided between the material box 9 and the U-shaped frame 7. The synchronization component includes a synchronization belt 18, a first rotating shaft 14 extending outwards through the side of the U-shaped frame 7, and a third rotating shaft 15 extending outwards through the side of the material box 9. A small synchronization pulley 17 is fixed to the surface of the third rotating shaft 15, and a large synchronization pulley 16 is fixed to the surface of the first rotating shaft 14. The synchronization belt 18 connects the surfaces of the large synchronization pulley 16 and the small synchronization pulley 17. When the first rotating shaft 14 rotates under the drive of the drive motor 26, the large synchronization pulley 16 rotates accordingly. The large synchronization pulley 16 drives the small synchronization pulley 17 to rotate via the synchronization belt 18, and the small synchronization pulley 17 drives the third rotating shaft 15 to rotate, thereby achieving synchronous movement between the conveying and reciprocating components.

[0034] Example 2: Reference Figures 1-4An improvement based on Example 1: Two connecting rods 25 are fixed inside the material box 9. Both connecting rods 25 extend outward and penetrate into the U-shaped frame 10. The side ends of the two connecting rods 25 are fixed with the same push plate 24. The push plate 24 is fixedly set inside the U-shaped frame 10. When the first screen 11 moves back and forth, the material on the first screen 11 is pushed outward by the push plate 24, making it convenient to remove the material.

[0035] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 26 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0036] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
