Description

Technical Field

[0001] This utility model belongs to the field of powder coating processing technology, and specifically relates to a powder coating sieving device. Background Technology

[0002] Powder coating is a solvent-free solid powder coating, mainly composed of resin, pigment, filler and additives. It is applied to the surface of the workpiece by electrostatic spraying or fluidized bed dip coating and then cured at high temperature to form a coating. During production, storage or transportation, the powder may be mixed with impurities or clump due to moisture or temperature changes. Sieving can ensure the purity of the coating and avoid defects such as particles and pinholes in the coating.

[0003] For example, Chinese patent CN211436897U discloses a powder coating sieving device, including a filter box.

[0004] The aforementioned powder coating sieving device effectively achieves high filtration efficiency by setting up structures such as stirring rods and filter screens. However, this patent still has some shortcomings that need to be improved. Relying solely on the stirring rods to disperse lumpy powders in the filter box, the stirring rods are unable to provide sufficient shearing and impact forces, which can easily lead to clumping and incomplete dispersion, resulting in poor dispersion and reduced sieving efficiency.

[0015] Example refer to Figures 1 to 4 The powder coating sieving device described in this embodiment includes a filter box 1. A filter screen 2 is fixedly connected to one side of the filter box 1. A guide pipe 3 is fixedly connected to the top of the filter box 1. A guide hopper 4 is fixedly connected to the top of the guide pipe 3. A first stirring component 5 is provided on one side of the guide pipe 3. A second stirring component 6 is provided inside the filter box 1 above the first stirring component 5. A power component 7 is provided on one side of the filter screen 2. Tensioning components 8 are provided on both sides of the power component 7. A door 11 is fixedly connected to one side of the filter box 1.

A bearing seat 53 is fixedly connected to one side of the top of the filter box 1. A shaft 52 is rotatably connected to the filter box 1 through the bearing seat 53. One side of the shaft 52 is fixedly connected to one side of the first stirring rod 51. When the shaft 52 rotates, it drives the first stirring rod 51 to rotate synchronously inside the feed pipe 3. The spiral blades can not only break up powder agglomerates, but also push the powder downward to avoid blockage of the feed pipe 3 and improve feeding efficiency.

[0017] refer to Figure 1-2 The second mixing assembly 6 includes a second mixing rod 61, which is rotatably connected to the filter box 1 above the filter screen 2. The second mixing rod 61 is located below the first mixing rod 51. A third mixing rod 62 is rotatably connected to both sides of the second mixing rod 61 inside the filter box 1. A drive gear 63 is fixedly connected to one side of the second mixing rod 61, and a driven gear 64 is fixedly connected to one side of the third mixing rod 62. The drive gear 63 and the driven gear 64 are meshed together. When the second mixing rod 61 rotates, the drive gear 63 drives the driven gears 64 on both sides to rotate in opposite directions, so that the second mixing rod 61 and the third mixing rod 62 form opposing mixing forces, which enhances the shearing and impact on the clumps and completely breaks up the stubborn clumps.

[0018] refer to Figure 1 The power assembly 7 includes a motor 71, which is fixedly connected to one side of the filter box 1. The output end of the motor 71 is fixedly connected to a drive sprocket 72. The drive sprocket 72 is driven by a chain 74 and connected to a driven sprocket 73. One side of the drive sprocket 72 is fixedly connected to one side of the second stirring rod 61, and one side of the driven sprocket 73 is fixedly connected to one side of the shaft 52. After the motor 71 is started, the drive sprocket 72 drives the chain 74 and the driven sprocket 73 to rotate, realizing the same power source to drive two sets of stirring assemblies, reducing equipment energy consumption. The adjustable speed function of the servo motor 71 can adjust the stirring speed according to the degree of powder agglomeration, improving applicability.

[0019] refer to Figure 3The tensioning assembly 8 includes a fixing block 81, which is fixedly connected to the filter box 1 on both sides of the chain 74. An assembly block 82 is fixedly connected to one side of the fixing block 81, and a spring 83 is fixedly connected to one side of the assembly block 82. A transmission block 84 is fixedly connected to one side of the spring 83, and a tension wheel 85 is rotatably connected to one side of the transmission block 84. One side of the tension wheel 85 is in contact with one side of the chain 74. A guide rod 86 is fixedly connected to the transmission block 84 on one side of the spring 83, and one side of the guide rod 86 is slidably connected inside the fixing block 81. When the chain 74 is slack, the spring 83 pushes the transmission block 84 and the tension wheel 85 to move toward the chain 74. The tooth groove of the tension wheel 85 meshes with the chain 74 to prevent slippage, and the guide rod 86 prevents the transmission block 84 from shifting, ensuring a stable tensioning effect.

[0020] refer to Figure 1 Inside the filter box 1, a guide seat 9 is fixedly connected to the lower side of the filter screen 2. One side of the guide seat 9 has a slope structure. A discharge pipe 10 is fixedly connected to the filter box 1 to the lower side of the motor 71. After qualified powder falls into the guide seat 9, it slides quickly along the slope to the discharge pipe 10 to avoid residue. At the same time, the slope structure makes it easy to clean the powder residue at the bottom of the filter box 1, reducing the difficulty of maintenance.

[0021] Operating principle and advantages: First, turn on the motor 71. The motor 71 drives the driven sprocket 73 to rotate via the drive sprocket 72 and chain 74. The driven sprocket 73 drives the shaft 52 and the first stirring rod 51 to rotate inside the feed pipe 3. At the same time, the drive sprocket 72 drives the second stirring rod 61 to rotate. The second stirring rod 61 drives the third stirring rods 62 on both sides to rotate in opposite directions through the meshing of the drive gear 63 and the driven gear 64. Then, the powder coating to be sieved is poured into the feed hopper 4. The powder enters the feed pipe... After passing through the feed pipe 3, the powder is initially broken up by the rotating first stirring rod 51 and pushed into the filter box 1. Under the opposing stirring of the second stirring rod 61 and the third stirring rod 62, the stubborn lumps of the powder falling into the filter box 1 are completely broken up. The qualified fine powder falls through the filter screen 2 into the bottom guide seat 9, slides along the slope of the guide seat 9 to the discharge pipe 10, and is discharged to the storage equipment. After the sieving is completed, the motor 71 is turned off, the box door 11 is opened, and the impurities and unbroken lumps remaining on the filter screen 2 are cleaned, making maintenance convenient.
