[0037] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0038] Example:

[0039] like Figures 1-6 As shown, a high-efficiency mixing device for powder coatings includes:

[0040] The mixing tank 1 has a discharge through hole at the bottom and symmetrical mounting grooves at the top. A mounting frame is fixedly sleeved on the bottom of its outer surface, and a support column is fixedly connected to the bottom end of its end.

[0041] The pneumatic tipping mechanism 2 is located at the bottom inner side of the mixing tank 1, and its input end is fitted with the inner side of the mounting groove on the top of the mixing tank 1.

[0042] The first connecting leg 4 is symmetrically located on the upper outer side of the surface of the mixing tank 1;

[0043] The mixing mechanism 5 is connected to the first connecting leg 4 by bolts and is located at the top of the mixing tank 1;

[0044] The exhaust filter mechanism 6 is bolted to the top of the mixing mechanism 5;

[0045] The cleaning mechanism 7 is detachably mounted on top of the mixing mechanism 5;

[0046] The discharge sealing mechanism 8 is fixedly located at the bottom of the mixing tank 1 and below the discharge through hole at the bottom of the mixing tank 1.

[0047] The working principle of the above technical solution is as follows:

[0048] During use, powder coating can be added to the inside of mixing tank 1. The pneumatic tipping mechanism 2 can deliver air from the bottom of the powder coating into the interior of mixing tank 1. At this time, the air can move upward from the inside of the powder coating and be discharged to the outside through the exhaust filter mechanism 6. The exhaust filter mechanism 6 can filter the powder coating carried by the air flow. The cleaning mechanism 7 can beat the exhaust filter mechanism 6 to clean the filtered powder coating, preventing excessive accumulation of powder coating and blockage, which would affect ventilation. At this time, the air flow can agitate the powder coating, and the stirring and mixing mechanism 5 can stably stir the powder coating during the agitation process, thereby efficiently stirring and mixing the powder coating. After stirring and mixing is completed, the discharge sealing mechanism 8 can be adjusted to discharge the stirred and mixed powder coating to the outside. The overall structure is simple and the operation is convenient and quick.

[0049] In another embodiment, such as Figure 4 As shown, the pneumatic tipping mechanism 2 includes an air supply end block 21 located at the bottom inner side of the mixing tank 1. An air outlet groove 22 is provided inside the air supply end block 21. A first guide slope 23 is provided on the inner side of the top of the air supply end block 21. A guide ring 24 is fixedly connected to the top of the air supply end block 21. A second guide slope 25 is provided on the inner side of the top of the guide ring 24. A first air supply pipe 26 is symmetrically provided on the top of the air supply end block 21. The inside of the guide ring 24 is in contact with the outer surface of the first air supply pipe 26. A second air supply pipe 27 is fixedly connected to the end of the first air supply pipe 26 away from the air supply end block 21. A third air supply pipe 28 is fixedly connected to the outer side of the second air supply pipe 27. The outer surface of the first air supply pipe 26 is in contact with the inner side of the mounting groove on the top of the mixing tank 1. An air pump is detachably connected to the other end of the third air supply pipe 28.

[0050] This allows the air pump to deliver gas into the gas delivery end block 21 through the third gas delivery pipe 28, the second gas delivery pipe 27, and the first gas delivery pipe 26. At the same time, the gas can be delivered into the mixing tank 1 through the gas outlet groove 22, so that the gas can move upward from inside the powder coating, thereby turning the powder coating and facilitating the mixing of the powder coatings.

[0051] In another embodiment, such as Figure 5 As shown, the mixing mechanism 5 includes a mounting top cover 51. The bottom edge of the mounting top cover 51 is symmetrically provided with limiting blocks 52. The outer surface of the limiting blocks 52 is in contact with the inner side of the mounting groove at the top of the mixing tank 1 and the outer side of the first air supply pipe 26. The top center of the mounting top cover 51 is provided with an output motor 53. The output end of the output motor 53 is provided with an output rod 54. The outer surface of the output rod 54 is symmetrically welded with mixing arms 55. The interior of the mounting top cover 51 is provided with a feeding channel 510 and an exhaust channel 511. The top of the mounting top cover 51 and above the feeding channel 510 is fixedly connected with a feeding frame 56. The interior of the feeding frame 56 is provided with a fixing slot 57. The inner side of the fixing slot 57 is movably inserted with a movable insert plate 58. The edge of the mounting top cover 51 is symmetrically provided with second connecting legs 59 that are adapted to the first connecting legs 4.

[0052] The top cover 51 is placed on top of the mixing tank 1 to facilitate the locking block 52 to engage with the inner side of the mounting groove at the top of the mixing tank 1. At the same time, the second connecting leg 59 can fit against the first connecting leg 4 and be fixed by bolts. Then, powder coating is added to the inside of the mixing tank 1 through the feeding frame 56. After the addition is completed, the movable insert plate 58 is inserted into the inner side of the fixing slot 57 to seal the feeding frame 56. Then, the pneumatic turning mechanism 2 turns the powder coating over, and the output motor 53 drives the output rod 54 to rotate the mixing arm 55, thereby further mixing the powder coating. The operation is convenient and quick.

[0053] In another embodiment, such as Figure 3 As shown, the exhaust filtration mechanism 6 includes a filter cloth 61 and a limiting fastening frame 62 that is bolted to the mounting top cover 51. The filter cloth 61 is located above the exhaust channel 511, and the limiting fastening frame 62 is located above the filter cloth 61. A rectangular channel 63 is provided inside the limiting fastening frame 62. The filter cloth 61 is made of a bag filter.

[0054] When the pneumatic material turning mechanism 2 is in use, the gas is discharged to the outside through the exhaust channel 511, and at the same time the filter cloth 61 can filter the powder coating carried by the gas, preventing the powder coating from being discharged to the outside, making operation convenient.

[0055] In another embodiment, such as Figure 3 As shown, the cleaning mechanism 7 includes a fixed mounting base plate 71, a mounting block 72 fixedly connected to the top of the fixed mounting base plate 71, a servo motor 73 provided at the top of the mounting block 72, a connecting cam 74 fixedly connected to the output end of the servo motor 73, a fixed base 75 fixedly connected to the top of the fixed mounting base plate 71, and a deflecting striking arm 76 movably connected inside the fixed base 75 via a connecting shaft. One end of the deflecting striking arm 76 is in contact with the filter cloth 61, and the other end of the deflecting striking arm 76 is in contact with the outer edge of the connecting cam 74.

[0056] The servo motor 73 can drive the connecting cam 74, so that when the connecting cam 74 rotates, it can cyclically press down one end of the deflecting striking arm 76, so that the deflecting striking arm 76 can deflect inside the fixed base 75. When the connecting cam 74 no longer presses down on one end of the deflecting striking arm 76, the other end of the deflecting striking arm 76 can strike downwards, thereby striking the filter cloth 61, so that the filter cloth 61 can filter and clean the powder coating attached to it. The operation is convenient.

[0057] In another embodiment, such as Figure 5As shown, the discharge sealing mechanism 8 includes a mounting base 81, which is located below the discharge through hole at the bottom of the mixing tank 1. The mounting base 81 has a discharge bottom hole 82 inside, and a third guide slope 83 is provided on the top inner side of the discharge bottom hole 82. A fixed mounting groove 84 is provided on the top of the mounting base 81, and a movable sealing plate 86 is movably inserted into the inner side of the fixed mounting groove 84. A fixed limiting arm 85 is symmetrically provided on one side of the mounting base 81, and a connecting limiting mechanism 87 is fixedly provided at one end of the movable sealing plate 86 near the fixed limiting arm 85.

[0058] The connecting limiting mechanism 87 can be adjusted to separate it from the fixed limiting arm 85, thus eliminating the connection limiting. Then, the connecting limiting mechanism 87 and the movable sealing plate 86 can be moved so that the movable sealing plate 86 can be disengaged from the inside of the fixed mounting groove 84, allowing the powder coating to be discharged to the outside through the third guiding inclined surface 83 and the discharge bottom hole 82, thus performing the discharge process. The operation is convenient.

[0059] In another embodiment, such as Figure 6 As shown, the connecting limiting mechanism 87 includes a fixed connecting block 871. A fixed mounting inner groove 872 is formed inside the fixed connecting block 871. Fixed guide grooves 873 are formed on both sides of the fixed connecting block 871, and the fixed guide grooves 873 communicate with the fixed mounting inner groove 872. A fixed through groove 874 is formed on the side of the fixed connecting block 871 away from the movable sealing plate 86, and the fixed through groove 874 communicates with the fixed mounting inner groove 872. The inner side of the fixed mounting inner groove 872... A fixing spring 875 is fixedly connected to the bottom end, and a connecting limiting block 876 is fixedly connected to the top end of the fixing spring 875. The outer surface of the connecting limiting block 876 slides and fits against the inner side of the fixing mounting inner groove 872, the fixing guide groove 873 and the fixing through groove 874 respectively. A connecting pressing block 877 is fixedly connected to the bottom end of the connecting limiting block 876 near the fixing through groove 874. A connecting handle 878 is fixedly connected to the side of the fixed connecting block 871 near the fixing through groove 874.

[0060] The connecting pressure block 877 can be pressed down to drive the connecting limit block 876 to move downward, compressing the fixing spring 875, so that the end of the connecting limit block 876 can be disengaged from the inside of the fixing limit arm 85, thus eliminating the connection limit. The overall structure is simple and the operation is convenient and quick.

[0061] The working principle of this utility model is as follows: First, the top cover 51 is placed on top of the mixing tank 1, allowing the limiting block 52 to engage with the inner side of the top mounting groove of the mixing tank 1. Simultaneously, the second connecting leg 59 engages with the first connecting leg 4 and is fixed with bolts. Then, powder coating is added to the mixing tank 1 through the feeding frame 56. After addition, the movable insert 58 is inserted into the inner side of the fixing slot 57 to seal the feeding frame 56. Then, the air pump delivers gas to the inside of the gas supply end block 21 through the third gas supply pipe 28, the second gas supply pipe 27, and the first gas supply pipe 26. Simultaneously, the gas is delivered into the mixing tank 1 through the gas outlet groove 22, allowing the gas to move upwards from the inside of the powder coating, thus agitating the powder coating and facilitating mixing. Then, the output motor 53 drives the output rod 54, causing the mixing arm 55 to rotate, thereby further stirring the powder coating and efficiently mixing it. After the powder coating is mixed, the connecting pressure block 877 is pressed down, causing the connecting limit block 876 to move downward, compressing the fixed spring 875. This allows the end of the connecting limit block 876 to disengage from the inside of the fixed limit arm 85, thus ceasing connection limiting. The connecting handle 878 is then pulled, causing the fixed connecting block 871 and the movable sealing plate 86 to move, allowing the movable sealing plate 86 to be pulled out from the inside of the fixed mounting groove 84. This allows the powder coating to be discharged to the outside through the discharge through hole and discharge bottom hole 82 at the bottom of the mixing tank 1. The overall structure is simple and the operation is convenient and quick.

[0062] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
