Description

Technical Field

[0001] The present invention relates to the technical field of powder coating grinders, and specifically to a production device for powder coatings with a powder cooling function. Background Art

[0002] Powder coatings are solid powder synthetic resin coatings composed of solid resins, pigments, fillers, and additives. Different from ordinary solvent-based coatings and water-based coatings, their dispersion medium is not solvent or water, but air. It has the characteristics of no solvent pollution, 100% film formation, and low energy consumption. Powder coatings are divided into two major categories: thermoplastic and thermosetting. The film appearance (gloss and leveling) of thermoplastic powder coatings is poor, and the adhesion to metals is also poor, 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 cures into a flat and hard film after chemical cross-linking. The film appearance, various mechanical properties, and corrosion resistance formed by this kind of coating can all meet the requirements of automotive finishing;

[0003] During the production process of powder coatings, it is necessary to mix the raw materials, then grind them, screen the powder after grinding to remove oversized particles to ensure the uniformity of the powder, and then cool the powder coatings in a timely manner to prevent heat generated by friction during the grinding process from causing thermal degradation of the resin or other components in the powder coatings, resulting in particle adhesion or aggregation, which affects the fluidity and uniformity of the powder.

The material receiving frame 52 is located directly below the material scattering mechanism 4. Four fixed crossbars 53 are slidably connected to the lower end of the placement plate 51, and two fixed crossbars 53 form a group.

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

[0041] A material blocking plate 611 is fixedly connected to the lower part inside the storage shell 61. Leakage holes 612 for leaking materials are formed in the material blocking plate 611.

[0042] Working principle of the present invention: Before grinding the powder coating, the proportioned raw materials are poured into the storage shell 61. The distribution plate 65 divides them into eight equal parts. First, the raw materials are poured into the chamber without the leakage holes 612. When the raw materials are higher than the distribution plate 65 and flow into the chamber with the leakage holes 612, the raw materials in the chamber above the leakage holes 612 flow into the feeding channel 14 through the leakage holes 612 and are ground and crushed by the grinding assembly 13. When the raw materials in this chamber are completely ground and crushed, the control end controls, and the second motor 63 drives the gear 64 to rotate. The gear 64 drives the fixed ring 66 to rotate in the distribution plate 65 through the meshing teeth 67, so that another chamber is located above the leakage holes 612. Then the second motor 63 stops working. Subsequently, the raw materials enter the grinding machine body 1 through the feeding channel 14 again, and the raw materials are quantitatively put into the grinding machine body 1, preventing the problem of grinding too much or too little raw materials at one time, lengthening the grinding time, and affecting the grinding accuracy;

[0043] After the raw materials are ground by the grinding assembly 13, they fall into the sliding frame 27. The first motor 24 drives the rotating disk 25 to rotate. The rotating disk 25 reciprocally pushes and pulls the sliding frame 27 to slide on the connecting long rod 22 through the connecting rotating rod 26. The sliding frame 27 drives the screen 273 to reciprocally move, so that the qualified ground raw materials pass through the screen 273 and fall onto the inclined plate body 281. After grinding is completed, hold the long rod 35 and pull it outwards to make the plug board 31 disengage from the slot 272, open the upper rotating door 11, and pull out the screening mechanism 2 as a whole from the grinding machine body 1 through the fixing plate 21. Then release the long rod 35, and the spring 33 pulls the fixed short board 34 to move towards the connecting sliding board 32. The fixed short board 34 drives the long rod 35 to reset through the plug board 31. After the screening mechanism 2 is pulled out as a whole, clean and collect the raw materials with larger particles on the screen 273. After cleaning is completed, hold the long rod 35 and pull it outwards, and put the screening mechanism 2 back into the grinding machine body 1. Release the long rod 35 to make the plug board 31 insert into the slot 272, close the upper rotating door 11, and make the fixing plate 21 located between the upper rotating door 11 and the blocking block and unable to move. During the reciprocating movement of the sliding frame 27, it drives the fixed column 274 to reciprocally move in the air chamber 29, extracts external air into the air chamber 29 through the second one-way intake valve 291, and then injects the air into the air injection pipeline 292;

[0044] After the sieved raw materials fall on the inclined plate body 281, they fall into the material receiving frame 52 along the inclined surface of the inclined plate body 281. At this time, since one end of the insertion plate 31 is inserted into the insertion slot 272, the insertion plate 31 drives the long rod 35 and the insertion rod 36 to reciprocate with the sliding frame 27. The insertion rod 36 drives the connecting sliding rod 49 to reciprocate in the sliding through groove 17 through the insertion hole 491. The connecting sliding rod 49 drives a plurality of sliding cross bars 41 to reciprocate in the grinding machine body 1 through a sliding cross bar 41 and a connecting rod. The sliding cross bar 41 drives the dispersing plate 44 to push and pull and stir the powder coating falling into the material receiving frame 52 through the connecting fixing rod 42, so that the lower layer of coating powder is mixed with the upper layer of coating powder, accelerating the heat dissipation of the powder coating. The air in the air injection pipeline 292 is injected into the connecting cross pipe 45 and the connecting vertical pipe 43 through the connecting hose 47, and then injected into the air holes 441 from the connecting vertical pipe 43 and sprayed downward from the air holes 441. Since there are a plurality of air holes 441, the air flow is dispersed, and only a slight air flow blows out from the air holes 441, blowing the powder coating in the material receiving frame 52, and blowing air to cool the powder coating when the powder coating is turned over;

[0045] When cooling the powder coating, the sliding cross bar 41 drives the convex plate 46 to move, and the convex plate 46 impacts the vertical plate 282, causing the vertical plate 282 to vibrate. The vertical plate 282 transmits the vibration feeling to the inclined plate body 281, so that the powder on the inclined plate body 281 quickly slides off the inclined plate body 281, 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 placing plate 51. The fixed cross bar 53 pushes the two sliding rods 532 away through the rotating rod 531, and the height of the placing plate 51 decreases. The placing plate 51 drives the material receiving frame 52 to separate from the dispersing plate 44. At this time, the material receiving frame 52 is removed from the placing plate 51, and the powder coating that has been ground, sieved, and cooled is collected. When the material receiving frame 52 is placed on the placing plate 51, the lower rotating door 12 is closed. The lower rotating door 12 pushes the H-shaped rod 54 to move into the grinding machine body 1 through extrusion. The H-shaped rod 54 pushes the sliding rod 532 to slide, and the sliding rod 532 squeezes and pushes the fixed cross bar 53 upward. The fixed cross bar 53 drives the placing plate 51 to rise, and the placing 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 grinding machine 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, preventing the material receiving frame 52 from falling off the limit baffle 511 when cooling the powder, resulting in the situation that the coating powder spills out of the material receiving frame 52.
