Description

Technical Field

[0001] The utility model relates to the field of paint mixing equipment, in particular to a paint mixing device. Background Art

[0002] Paint, traditionally known as varnish in China, is a viscous liquid that is applied to the surface of an object to be protected or decorated and can form a firmly attached continuous film with the coated object. It is usually based on resin, oil, or emulsion, with or without pigments and fillers, and with corresponding additives, and is prepared with organic solvents or water.

[0003] A Chinese patent discloses a coating mixing device, with the publication number CN214319963U. The problem to be solved is that in the existing coating stirring process, most of the stirring is done manually. During the stirring process, uneven force is applied, which leads to uneven stirring between the coatings, poor mixing effect, and poor coating quality. However, when the coating is stored, the coating often agglomerates, which easily affects the final mixing effect (if agglomeration occurs when the coating is mixed in proportion, the proportion of a certain part of the material will be reduced, and the final mixed liquid product is not in the ideal proportion). In addition, when mixing the coating, since the coating itself is relatively viscous, it is easy to be adsorbed on the inner wall of the mixing barrel, and manual cleaning is required, which increases the workload of the staff. Therefore, it is very necessary to design a coating mixing device. Utility Model Content

[0038] During operation, when various coatings are poured from the feed hopper 4 into the housing 1, the lumps in the coatings are crushed or stirred by the crushing roller 31, and then enter the mixing barrel 6 for full mixing, to ensure that the ratio of each component in the final finished emulsion is the set ratio (there will be no ratio deviation due to agglomeration, and the agglomerates cannot be fully stirred in the mixing barrel 6, but can be broken by the crushing roller 31), thereby improving the quality of the finished emulsion.

[0039] like Figure 4 and Figure 5 As shown, the left part of the partition 2 is inclined downward, a pair of crushing rollers 31 are arranged on the middle surface of the partition 2, and a discharge port 33 is opened on the right part of the partition 2; the feed hopper 4 is located just above the left part of the partition 2; when the coating is poured from the feed hopper 4, it flows to the right along the inclined part of the left part of the partition 2, and the agglomerates entrained by the liquid are crushed when passing through the crushing roller 31;

In addition, a discharge hopper 34 is installed at the discharge port 33, and the discharge hopper 34 guides the coating from the upper cavity to the mixing barrel 6 (if there is only a discharge port 33 but no discharge hopper 34, the emulsion in the upper cavity will directly flow horizontally on the bottom surface of the partition 2, and the provision of the discharge hopper 34 can guide the emulsion).

[0043] Furthermore, if Figure 4 As shown, an inclined baffle 35 is provided on the surface of the right portion of the partition 2 and at the rear side of the discharge port 33 to allow the emulsion to flow out of the discharge port 33 better.

[0049] Specifically, a plurality of cylinders B14 are fixed on the bottom surface of the partition 2, and the output shaft of the cylinder B14 is a connecting rod 15, and a bracket 10 is suspended at the lower end of the connecting rod 15; a first motor 11 is fixed on the bracket 10, and the output shaft of the first motor 11 is a stirring shaft 12, and a plurality of stirring rods 13 are provided on the stirring shaft 12; the bracket 10 is driven up and down by the cylinder B14, thereby realizing the up and down movement of the stirring shaft 12 and the stirring rod 13.

[0050] like Figure 4 and Figure 5 As shown, a cleaning mechanism 7 is also provided at the mixing barrel 6. Specifically, the cleaning mechanism 7 includes an annular frame 71, an annular scraper 72, and a nozzle 74; wherein the annular frame 71 is fixedly provided along the barrel mouth of the mixing barrel 6, and a plurality of cylinders A73 are installed circumferentially on the annular frame 71, and the plurality of cylinders A73 are connected to the annular scraper 72, and the annular scraper 72 is in contact with the inner wall of the mixing barrel 6. In addition, a plurality of nozzles 74 are also provided circumferentially on the annular frame 71, and the nozzles 74 are connected to the water pump 76 via a water pipe 75. The annular scraper 72 is driven by the cylinder A73 to scrape and clean the inner wall of the mixing barrel 6, and the cleaning water is sprayed out through the nozzle 74.

[0051] In this embodiment, a fixing rod 16 is welded on the circumference of the outer wall of the mixing barrel 6, and the fixing rod 16 is installed on the inner wall of the box body 1 through a damping member 17. The damping member 17 has a variety of designs, for example, the damping member 17 includes a spring and a long tube, one end of the long tube is hinged on the inner wall of the box body 1, and the other end of the long tube is inserted with the fixing rod 16; a spring is sleeved at the joint between the fixing rod 16 and the long tube, and there are protrusions on the fixing rod 16 and the long tube, and the two ends of the spring are respectively against the protrusions of the fixing rod 16 and the long tube. When working, the fixing rod 16 can move in extension and contraction in the long tube and is subjected to the force of the spring, which plays a damping role.

[0052] Furthermore, the bottom of the mixing barrel 6 has an integrated material pipe 8 , the mixing barrel 6 is placed on the inner bottom plate of the box body 1 , and the material pipe 8 passes through the inner bottom plate of the box body 1 ; a closing valve 9 is provided on the pipe 8 .

The air extractor 21 forms a negative pressure in the lower chamber, which is conducive to the smooth flow of the emulsion in the upper chamber to the mixing barrel 6 in the lower chamber; the air filter box 23 filters the emulsion substances.

[0055] When the paint mixing device is used, paint is added to the interior of the box 1 through the feed hopper 4, and the paint is crushed and decomposed through the decomposition component 3; the crushing situation can be observed by opening the cover plate 5 and the lumps can be cleaned to avoid the material jamming phenomenon; the decomposed paint will enter the mixing barrel 6, and the first motor 11 drives the stirring rod 13 to stir the paint in the mixing barrel 6 through the stirring shaft 12 to make it fully blended; the cylinder B14 uses the connecting rod 15 to adjust the height of the bracket 10, which can change the stirring position of the stirring rod 13 and stir the materials at different heights in the mixing barrel 6; the mixing barrel is fixed by the fixing rod 16 and the damping 17. 6 plays a supporting and shock absorbing role. Heating by the heating tube 18 can improve the activity of the paint, increase the mixing effect, and improve the mixing quality. The paint odor generated during mixing can be sucked out by the vacuum pump 21 (the vacuum pump 21 can also create a negative pressure in the lower cavity, which is conducive to the smooth leakage of materials from the upper cavity to the lower cavity), and the odor is discharged into the air filter box 23 through the air guide pipe 22 for filtering treatment to avoid polluting the air environment. Opening the closing valve 9 can allow the mixed paint to pass through the material pipe 8 into the collecting barrel 26 for storage. The connection effect between the pillars 24 can be increased through the connecting plate 25, thereby improving stability.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
