Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, specifically to a high-efficiency coating quality-improving grinding machine. Background Technology

[0002] In the coatings processing industry, the grinding process is central, playing a decisive role in the final quality and performance of the coatings. High-quality grinding ensures that the coatings have good dispersibility, fineness, and uniformity. These characteristics directly affect the coatings' performance in practical applications, such as film smoothness, gloss, adhesion, and weather resistance. One of the main raw materials for coatings is sericite, a layered potassium-containing aluminosilicate.

[0003] A high-efficiency coating quality-improving grinding machine, disclosed in publication number CN 216125696 U, includes a housing. A casing is mounted on the top of the housing, and a discharge port is located at the bottom. A grinding seat is positioned at the top of the inner cavity of the housing, with an insertion hole in the center. The grinding seat is funnel-shaped and has a heating plate on its upper surface. Heating wires are inserted into the inner cavity of the heating plate. An inclined scraper is welded to the outer wall of the grinding seat, contacting the outer wall of the heating plate. A motor bracket is located at the bottom of the inner cavity of the housing, and a grinding motor is mounted on the bracket. This high-efficiency coating quality-improving grinding machine rationally integrates the grinding and heating functions of coatings into a single device. While grinding coatings, it can simultaneously heat coatings that become viscous in winter, effectively improving grinding efficiency and quality.

[0004] However, the above-mentioned grinding mill still has some shortcomings in use. On the one hand, it lacks a pretreatment function for the coating. When there is agglomeration in the coating, directly entering the grinding stage will lead to a significant decrease in grinding efficiency and make it difficult to grind the agglomerated coating to the required fineness, affecting the overall quality of the coating. On the other hand, it lacks an efficient screening mechanism after grinding, making it impossible to quickly and accurately screen out coatings that meet the particle size requirements, resulting in a large amount of substandard coatings being mixed into the finished product, reducing the product qualification rate. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency coating quality-improving grinding machine. It solves two problems: firstly, the lack of pre-treatment for coatings leads to a significant decrease in grinding efficiency when coatings contain agglomerates, making it difficult to grind the agglomerated coatings to the required fineness, thus affecting the overall quality of the coatings; secondly, the lack of an efficient screening mechanism after grinding prevents the rapid and accurate screening of coatings that meet particle size requirements, resulting in a large amount of substandard coatings being mixed into the finished product, reducing the product's pass rate.

[0006] This utility model provides the following technical solution: a high-efficiency coating quality improving grinding machine, including a grinding box, a connecting block fixedly connected between the inner walls of the grinding box, a grinding groove opened on the connecting block, a grinding cone rotatably connected to the inner top wall of the grinding box, a first motor fixedly connected to the upper surface of the grinding box, the output end of the first motor extending into the interior of the grinding box and fixedly connected to the grinding cone, and a pre-crushing component provided on the upper surface of the grinding box;

[0021] Example 1: A high-efficiency coating quality improving grinding machine includes a grinding box 1, a connecting block 2 fixedly connected between the inner walls of the grinding box 1, a grinding groove opened on the connecting block 2, a grinding cone 3 rotatably connected to the inner top wall of the grinding box 1, a first motor 4 fixedly connected to the upper surface of the grinding box 1, the output end of the first motor 4 extending into the interior of the grinding box 1 and fixedly connected to the grinding cone 3, and a pre-crushing component provided on the upper surface of the grinding box 1;

[0022] The grinding box 1 has two connecting plates 5 fixedly connected to its inner side walls. Each connecting plate 5 has a set of movable grooves 6 on its surface. Each movable groove 6 has a connecting rod 7 slidably fitted inside it. The top of each set of connecting rods 7 is fixedly connected to a mounting plate 8. Mounting frames 9 are mounted on the two mounting plates 8. Filter plates 10 are fixedly installed between the inner walls of the mounting frames 9.

[0023] Example 2: The difference between this example and Example 1 is that the pre-crushing component includes a crushing box 11 fixedly installed on the top of the grinding box 1. Two crushing rollers 12 are rotatably connected between the two inner side walls of the crushing box 11. The bottom of the crushing box 11 is connected to a discharge pipe 13. The bottom end of the discharge pipe 13 is located above the grinding tank, which facilitates the pre-crushing treatment of the agglomerated coating and ensures the subsequent grinding effect.

[0024] Example 3: The difference between this example and Example 1 is that a second motor 14 is fixedly connected to one side of the crushing box 11. The output end of the second motor 14 extends into the interior of the crushing box 11 and is fixedly connected to one of the crushing rollers 12. One end of each of the two crushing rollers 12 extends into the exterior of the crushing box 11 and is fixedly fitted with a gear 15. The two gears 15 mesh with each other. The rotation of the second motor 14 can simultaneously drive the two crushing rollers 12 to crush the paint.

[0025] Example 4: The difference between this example and Example 1 is that a rotating rod 16 is rotatably connected between the two inner side walls of the crushing box 11. Two eccentric wheels 17 are fixedly sleeved on the surface of the rotating rod 16. A long plate 18 is fixedly connected between the bottom ends of each set of connecting rods 7. The position of the eccentric wheel 17 corresponds to the long plate 18. A first spring 19 is sleeved on the surface of each connecting rod 7. A third motor 20 is fixedly connected to the side of the crushing box 11. The output end of the third motor 20 extends into the interior of the crushing box 11 and is fixedly connected to the rotating rod 16, which can make the filter plate 10 vibrate up and down, resulting in a better filtration effect on the coating.

[0026] Example 5: The difference between this example and Example 1 is that two T-shaped blocks 21 are fixedly connected to the lower surface of the mounting frame 9. The upper surfaces of the two mounting plates 8 are provided with mounting grooves 22 that match the T-shaped blocks 21. A set of through holes 23 are provided on the sides of the two mounting plates 8. A locking rod 24 is slidably fitted inside each through hole 23. A set of locking grooves 25 that match the locking rods 24 are provided on the surfaces of the two T-shaped blocks 21. A second spring 26 is fitted on one outer end of each locking rod 24. A short plate made of iron is fixedly connected to one outer end of both sets of locking rods 24. Magnets 28 are fixedly connected to the sides of the two mounting plates 8, which facilitates the quick installation and disassembly of the mounting frame 9 and the filter plate 10, and makes it easy to remove unqualified coatings after grinding.

[0027] Example 6: The difference between this example and Example 1 is that the surface of the crushing box 11 is provided with a protective door 27 by a hinge, the protective door 27 is provided with a handle, and a collection box is placed on the bottom wall of the inside of the crushing box 11 to facilitate the collection and removal of the filtered paint.

[0028] In summary, this high-efficiency coating grinding machine, when in use, involves adding the coating to be ground into the grinding chamber 11. The rotation of the second motor 14 and the transmission of two gears 15 cause the two grinding rollers 11 to pre-crush the coating, preventing it from clumping and affecting subsequent grinding efficiency. The pre-crushed coating falls into the grinding trough, where the rotation of the first motor 4 drives the grinding cone 3 for further grinding. The ground coating falls onto the filter plate 10 of the mounting frame 9 for filtration and sieving. Simultaneously, the rotation of the third motor 20 drives the rotating rod 16 and the eccentric wheel 17 to rotate, causing the eccentric wheel 17 to squeeze the long plate 18. The pressure pushes the filter plate 10 up and down to vibrate through the elastic force of the first spring 19, which improves the screening and filtration effect of the coating. The filtered coating falls into the collection box for collection. When it is necessary to process the unqualified coating, open the protective door 27 and pull the two locking rods 24 outward to disengage them from the locking groove 25. Then the mounting block 9 and the filter plate 10 can be removed from the two mounting plates 8, and the unqualified coating inside can be taken out for re-grinding. It is convenient and quick. When using this grinder, the coating can be pre-treated to ensure the grinding effect, and the ground coating can be quickly screened.
