Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for coating product production, and in particular to a powder coating premixing device. Background Technology

[0002] When using powder coatings, it is sometimes necessary to mix different powder coatings using a powder coating premixing device. Also, if the powder coatings become damp during storage, they may agglomerate, which can seriously affect their subsequent use.

[0003] Chinese utility model patent CN221062497U discloses a powder coating premixing device, relating to the field of coating premixing technology. The powder coating premixing device includes: a mixing chamber; a mixing mechanism connected to the mixing chamber, the mixing mechanism including a turntable; the turntable is rotatably connected inside the mixing chamber, and multiple cylindrical bosses are fixedly connected to the upper surface of the turntable, the cylindrical bosses being positioned near the edge of the turntable; a mixing mesh cover with an open top and concentrically arranged is fixedly connected to the upper surface of each cylindrical boss; the mixing chamber is connected to a drive assembly for driving the turntable. This powder coating premixing device has the advantage of good mixing effect.

[0004] However, the above-mentioned device is rather cumbersome when dumping raw materials. Powder coatings can easily fall between the mixing screen and the mixing chamber, preventing the aggregate from being ground and causing it to be collected directly. Furthermore, because the turntable rotates inside the mixing chamber, there is a gap between it and the inner wall of the mixing chamber. During the grinding process, some powder coatings can fall into the cavity below the turntable, clogging the gears and preventing the grinding mechanism from operating.

[0005] In view of this, there is a need to further improve a powder coating premixing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a powder coating premixing device that can quickly stir and grind agglomerated powder coatings, facilitating subsequent processing and making it easy to collect the ground powder coatings.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, a powder coating premixing device includes a support frame 1, a mixing box 2, and a first stirring component.

[0034] The mixing box 2 is mounted on the support frame 1; the mixing box is Y-shaped, with two openings at the upper ends of the mixing box 2 and the outlet at the bottom port; a cover 3 is provided at the two openings; and a first filter screen 4 is provided at the outlet.

[0035] In this embodiment, as Figure 2 As shown, a collection frame 5 is placed at the bottom of the support frame 1, directly below the first filter screen 4, to facilitate the collection of the sieved powder coating.

[0036] The first stirring component includes a first rotating shaft 6, a first stirring body 7, and a first motor 8; the first rotating shaft 6 is horizontally rotatably mounted on the support frame 1 and passes through the intersection of the three channels of the mixing box 2; as shown Figure 3 As shown, the first stirring body 7 is sleeved and fixed on the first rotating shaft 6 and located inside the mixing box 2; the first motor 8 is mounted on the support frame 1 and is used to drive the first rotating shaft 6 to rotate, thereby realizing the stirring and grinding operation of the powder coating in the mixing box 1.

[0037] In this embodiment, a powder coating premixing device further includes a second stirring component, which comprises a second rotating shaft 9, a second stirring body 10, and a second motor 11; as shown Figure 3As shown, the second rotating shaft 9 is horizontally rotatably mounted on the support frame 1 and passes through the lower two outer walls of the mixing box 2; the second stirring body 10 is sleeved and fixed on the second rotating shaft 9; the second motor 11 is used to drive the second rotating shaft 9 to rotate; with this configuration, the powder coating is stirred and ground in conjunction with the first stirring body 7, so that the agglomerated powder coating is re-stirred and ground into powder.

[0038] In this embodiment, bearing oil seal assemblies 12 are provided at the connection between the first rotating shaft 6 and the mixing box 2 and at the connection between the second rotating shaft 9 and the mixing box 2. These assemblies support the first rotating shaft 6 and effectively prevent powder coating from entering between the bearings and causing damage, thereby ensuring the normal operation of the first rotating shaft 6 and the second rotating shaft 9.

[0039] In this embodiment, the mixing box 2 is provided with a second filter screen 13, which is located between the first stirring member and the second stirring member. The aperture of the second filter screen 13 is larger than that of the first filter screen 4. This arrangement allows larger clumps of powder coating to continue to be stirred and ground by the first stirring member, while the remaining powder coating and smaller clumps of powder coating pass through the second filter screen 13. The smaller clumps of powder coating are further stirred and ground by the second stirring member and finally screened and collected by the first filter screen 4.

[0040] In this embodiment, the frame of the second filter screen 13 is hinged to the lower part of the mixing box 2. A locking member 14 is provided on the frame of the second filter screen 13. When there are many clumps and blockages on the second filter screen 13, the locking member 14 can be opened and the second filter screen 13 can be rotated to clean the blockages on the second filter screen 13.

[0041] Furthermore, in this embodiment, as Figure 4 As shown, the upper and lower surfaces of the frame of the second filter screen 13 are provided with sealing rings 15, which effectively improves the sealing between the second filter screen 13 and the mixing box 2.

[0042] When processing powder coatings that have been stored for a long time, the powder coatings are first poured into the mixing box 2 through the two openings. The first and second agitators are then started. The clumps of powder coatings are stirred and ground by the first agitator 7. After passing through the second filter screen 13, the smaller clumps are further stirred and ground by the second agitator 10. Finally, the fine powder coatings are collected by the collection frame through the first filter screen 4.

[0043] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
