Description

Technical Field

[0001] The invention relates to the technical field of powder coating grinders, in particular to a production device for powder coatings with a grinding function. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coatings are divided into two categories: thermoplastic and thermosetting. Thermoplastic powder coatings have poor coating film appearance (gloss and leveling) and poor adhesion to metal, so they are rarely used in the field of automotive painting. Automotive painting generally uses thermosetting powder coatings. Thermosetting powder coatings use thermosetting synthetic resins as film-forming substances. During the drying process, the resin first melts and then solidifies into a smooth and hard coating film after chemical cross-linking. The film appearance, various mechanical properties and corrosion resistance formed by this type of coating can meet the requirements of automotive finishing;

[0003] In the process of producing powder coatings, the raw materials need to be proportioned and then ground. After grinding, the powder needs to be sieved to remove oversized particles and ensure that the powder is uniform. The powder coating then needs to be cooled in time to prevent friction from generating heat during the grinding process, which may cause thermal degradation of the resin or other components in the powder coating, resulting in particle adhesion or aggregation, and affecting the fluidity and uniformity of the powder.

The sliding cross bar is connected to the sliding frame through a connecting mechanism. The sliding frame drives the sliding cross bar to move back and forth, and the powder coating after screening in the docking frame is turned over. The coating is turned over during the working process of coating powder screening, which saves energy consumption.

[0040] A material unloading mechanism 6 for unloading materials is arranged at the upper end of the grinder body 1, and the material unloading mechanism 6 includes a material storage shell 61 fixedly connected to the upper end of the grinder body 1, a support connecting plate 62 is fixedly connected to one side of the material storage shell 61, a second motor 63 is fixedly arranged on one side of the support connecting plate 62, a gear 64 is fixedly connected to the output end of the second motor 63, a dividing plate 65 is rotatably connected inside the material storage shell 61, the dividing plate 65 is in a cross shape, and the dividing plate 65 divides the dividing plate 65 into eight chambers, a fixing ring 66 is fixedly connected to the upper end of the dividing plate 65, a fixing ring 66 is fixedly connected to the outer side of the dividing plate 65, and the dividing plate 65 is meshed with the gear 64 through the fixing ring 66.

[0041] A material blocking plate 611 is fixedly connected to the lower part of the material storage shell 61 , and a material leakage hole 612 for material leakage is opened on the material blocking plate 611 .

[0042] The working principle of the present invention is as follows: before grinding the powder coating, the raw materials with good proportion are poured into the storage shell 61, and the dividing plate 65 is evenly divided into eight parts. The raw materials are first poured into the chamber without the leakage hole 612. When the raw materials are higher than the dividing plate 65 and flow into the chamber with the leakage hole 612, the raw materials in the chamber above the leakage hole 612 flow into the feed channel 14 through the leakage hole 612, and are ground and crushed by the grinding assembly 13. When the raw materials in the chamber are completely ground and crushed, the control end controls the second motor 63 to drive the gear 64 to rotate, and the gear 64 drives the fixed ring 66 to rotate in the dividing plate 65 through the meshing teeth 67, so that another chamber is located above the leakage hole 612, and then the second motor 63 stops working, and then the raw materials enter the grinder body 1 through the feed channel 14 again, and the raw materials are quantitatively fed into the grinder body 1 to prevent the problem of grinding too much or too little raw materials at one time, prolonging the grinding time, and affecting the grinding accuracy.

[0043] After the raw material is ground by the grinding assembly 13, it falls into the sliding frame 27, and the first motor 24 drives the rotating disk 25 to rotate. The rotating disk 25 pushes and pulls the sliding frame 27 back and forth through the connecting rotating rod 26 to slide on the connecting long rod 22. The sliding frame 27 drives the screen 273 to move back and forth, so that the ground qualified raw material passes through the screen 273 and falls onto the inclined plate body 281. After the grinding is completed, the long rod 35 is held and pulled outward to disengage the plug plate 31 from the slot 272, and the upper rotating door 11 is opened. The screening mechanism 2 is pulled out of the grinder body 1 as a whole through the fixed plate 21, and then the long rod 35 is released, and the spring 33 pulls the fixed short plate 34 to move toward the connecting slide plate 32. , the fixed short plate 34 drives the long rod 35 to reset through the plug plate 31. After the screening mechanism 2 is pulled out as a whole, the larger particles of raw materials on the collecting screen 273 are cleaned. When the cleaning is completed, the long rod 35 is held and pulled outward, and the screening mechanism 2 is placed in the grinding machine body 1, and the long rod 35 is loosened to insert the plug plate 31 into the slot 272. The upper rotating door 11 is closed, so that the fixed plate 21 is located between the upper rotating door 11 and the blocking block and cannot move. In the process of the reciprocating movement of the sliding frame 27, the fixed column 274 is driven to reciprocate in the air chamber 29, and the external air is drawn into the air chamber 29 through the second one-way air inlet valve 291, and then the air is injected into the air injection pipe 292;

[0044] When the screened raw materials fall on the inclined plate body 281, they fall into the material receiving frame 52 along with the inclined surface of the inclined plate body 281. At this time, since one end of the insert plate 31 is inserted into the slot 272, the insert plate 31 drives the long rod 35 and the insert rod 36 to move back and forth with the sliding frame 27. The insert rod 36 drives the connecting slide rod 49 to move back and forth in the sliding groove 17 through the insertion hole 491. The connecting slide rod 49 drives multiple sliding cross bars 41 to move back and forth in the grinding machine body 1 through a sliding cross bar 41 and a connecting rod. The sliding cross bar 41 drives the scattering plate 44 through the connecting fixed rod 42. 4. The powder coatings falling into the material receiving frame 52 are pushed, pulled and stirred to mix the powders of the lower layer of coatings with the powders of the upper layer of coatings, so as to accelerate the heat dissipation of the powder coatings. The air in the air injection pipe 292 is injected into the connecting horizontal pipe 45 and the connecting vertical pipe 43 through the connecting hose 47, and then injected into the air hole 441 from the connecting vertical pipe 43, and then ejected downward from the air hole 441. Since a plurality of air holes 441 are provided, the air flow is dispersed, and only a slight air flow is blown out from the air hole 441 to blow the powder coatings in the material receiving frame 52. When the powder coatings are turned over, the powder coatings are blown to cool down.

[0045] When cooling the powder coating, the sliding cross bar 41 drives the convex plate 46 to move, and the convex plate 46 hits the vertical plate 282, causing the vertical plate 282 to vibrate. The vertical plate 282 transmits the vibration to the inclined plate body 281, causing the powder on the inclined plate body 281 to slide off the inclined plate body 281 quickly, preventing the coating powder from remaining on the inclined plate body 281.

[0046] After the grinding is completed, the lower rotating door 12 is opened. At this time, the H-shaped rod 54 is no longer in contact with the lower rotating door 12. Due to the weight of the material receiving frame 52 and the coating powder in the material receiving frame 52, when the lower rotating door 12 is opened, the material receiving frame 52 presses down the fixed cross bar 53 through the placement plate 51, and the fixed cross bar 53 pushes the two sliding rods 532 away through the rotating rod 531, the height of the placement plate 51 is reduced, and the placement plate 51 drives the material receiving frame 52 to separate from the scattering plate 44. At this time, the material receiving frame 52 is removed from the placement plate 51, and the powder coating that has been ground, screened and cooled is collected. When the material receiving frame 52 is placed on the placement plate 51 After that, close the upper and lower rotating doors 12, the lower rotating door 12 pushes the H-shaped rod 54 to move into the grinder body 1 by squeezing, the H-shaped rod 54 pushes the sliding rod 532 to slide, the sliding rod 532 squeezes and pushes the fixed cross bar 53 upward, the fixed cross bar 53 drives the placement plate 51 to rise, the placement plate 51 pushes the material receiving frame 52 to rise, so that the upper edge of the material receiving frame 52 fits with the inside of the grinder body 1, and the powder will not float out of the material receiving frame 52. The limit baffle 511 blocks the material receiving frame 52 to prevent the material receiving frame 52 from falling from the limit baffle 511 when the powder is cooled, so that the coating powder will spill out of the material receiving frame 52.

The protection scope of the present invention is defined by the claims.
