Description

Technical Field

[0001] The utility model relates to the technical field of blanking devices, and particularly relates to a powder material blanking device for paint production. Background Art

[0002] Paint is coated on the surface of an object to be protected or decorated and can form a continuous film firmly attached to the object to be painted. During the production process of paint, many powder materials usually need to be added. However, the current blanking devices are not convenient for screening powder materials with larger particles or agglomerated ones, and are prone to blockage during blanking, thus making it inconvenient to quickly blank the powder materials.

[0003] After retrieval, the utility model with the patent publication number CN211366289U discloses a powder material blanking device for paint production, which can blank powder materials through a rectangular blanking pipe. And according to the baffle arranged on the inner wall near the top of the rectangular blanking pipe, the materials are preliminarily separated. Moreover, a retaining net is arranged on the inner wall of the rectangular support, which can effectively isolate and collect large particle impurities and the like of the materials. After screening, the materials fall into the feeding cylinder. Although it is convenient for screening powder materials, the large particle powder materials after screening need to be collected manually and then put into the blanking pipe for screening and blanking. Repeated screening and collection are likely to reduce the blanking efficiency of powder materials, thus affecting the production efficiency of paint. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0043] As Figures 1 to 5 shown, this embodiment proposes a powder material blanking device for coating production, including a material conveying cylinder 1, a spiral material conveying rod 2 rotatably connected in the material conveying cylinder 1, and further including a blanking cylinder 3, a blanking pipe 4, a filtering cone cylinder 5 and a rotating rubber rod 6.

[0044] Refer to Figure 1 、 Figure 2 and Figure 4, the rotating assembly includes a protective cover 7, a first motor 8, a rotating column 10, a rotating cylinder 11 and a compression spring 12. The protective cover 7 is detachably connected to the top end of the blanking cylinder 3. A plurality of fixing plates 23 are fixedly connected to the bottom end of the protective cover 7. Fixing screws 24 are threadedly connected between the plurality of fixing plates 23 and the outer side wall of the blanking cylinder 3, which facilitates the installation and disassembly of the protective cover 7 on the blanking cylinder 3. The first motor 8 is installed on the top end of the protective cover 7 through a protective frame 9. The rotating column 10 is fixedly connected to the output end of the first motor 8, and the rotating column 10 is rotatably connected through the protective cover 7. A plurality of rotating cylinders 11 are provided. The plurality of rotating cylinders 11 are all fixedly connected to the rotating column 10, and the rotating rubber rod 6 is slidably connected through the rotating cylinder 11. The compression spring 12 is fixedly connected between the rotating rubber rod 6 and the inner side wall of the rotating cylinder 11. Two limiting blocks 22 are symmetrically connected to the rotating rubber rod 6. A limiting groove for the limiting block 22 to slide is provided on the rotating cylinder 11, which facilitates the limitation of the movement of the rotating rubber rod 6 on the rotating cylinder 11. An inlet is provided on the protective cover 7. A protective plate 25 is rotatably connected through a driving seat at the inlet. Through the inlet, it is convenient for the powder material to enter the blanking cylinder 3. At the same time, through the protective plate 25, the inlet can be protected, so as to reduce the entry of external dust into the blanking cylinder 3, and at the same time, it can prevent the powder material from flying into the air during blanking. A rubber sleeve 27 is fixedly sleeved at the bottom end of the rotating column 10. A groove matching the rotating column 10 is provided on the rubber sleeve 27, which is convenient for grinding and hitting the material at the bottom of the filtering cone 5, so as to reduce the powder material remaining on the filtering cone 5;

[0045] By starting the first motor 8, the first motor 8 rotates the rotating column 10, which can drive the plurality of rotating cylinders 11 to rotate, so as to drive the plurality of rotating rubber rods 6 to rotate. At the same time, the rotating rubber rod 6 will move back and forth a certain distance in the rotating cylinder 11 through the compression spring 12 and the limiting block 22, so as to enable the rotating rubber rod 6 to repeatedly hit the filtering cone 5, thereby driving the powder material to shake back and forth a certain distance, and then facilitating the dispersion and pulverization of the powder material.

[0046] Reference Figure 3 And Figure 5 , the connecting assembly includes a connecting plate 13, a connecting cylinder 14, a connecting rod 15 and a connecting spring 16.

A connecting groove for the connecting strip 26 to slide is provided on the inner side wall of the connecting cylinder 14, which can increase the sliding stability of the connecting rod 15 on the connecting cylinder 14;

[0047] Through the cooperation of the connecting spring 16 and the connecting bar 26, the connecting rod 15 can move within the connecting cylinder 14. When the powder material drops onto the filtering conical cylinder 5, multiple connecting rods 15 will be impacted and move within multiple connecting cylinders 14 respectively. Due to the elasticity of the connecting spring 16, it is convenient for the multiple connecting rods 15 to move back and forth within the multiple connecting cylinders 14 respectively, so that the filtering conical cylinder 5 can move back and forth within the feeding cylinder 3 for a certain distance, thereby scattering the large-particle powder material on the filtering conical cylinder 5.

[0049] Through the base 17, it is convenient to stably support the feeding cylinder 3. Through the cooperation of the two support frames 18 and the two connecting frames 19, the feeding cylinder 1 can be stably supported.

[0050] Reference Figure 3 , one side of the feeding cylinder 1 is fixedly connected with a mounting frame 20, and a second motor 21 is installed on the mounting frame 20. The output end of the second motor 21 penetrates the side wall of the feeding cylinder 1 and is fixedly connected with the spiral feeding rod 2;

[0051] By rotating the spiral feeding rod 2 by the second motor 21, the powder material can be conveyed and discharged.

[0052] In this embodiment, when the powder material enters the feeding cylinder 3 through the feeding port, it will fall on the filtering conical cylinder 5 for filtering. At the same time, the first motor 8 is started, so that the rotating column 10 can drive multiple rotating cylinders 11 to rotate, so as to drive multiple rotating rubber rods 6 to rotate, thereby enabling the rotating rubber rods 6 to collide and strike the filtering conical cylinder 5, and then facilitating the filtering conical cylinder 5 to drive the powder material to shake and scatter. The scattered powder material will enter the feeding cylinder 1 through the feeding pipe 4, and then the second motor 21 is started to rotate the spiral feeding rod 2 by the second motor 21, so that the powder material can be conveyed and discharged.

[0053] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
