Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically to a graded circulating grinding device for topcoat. Background Technology

[0002] Topcoat, also known as final coat, is the last layer of paint applied in a multi-layer coating process. It has good resistance to external conditions, as well as necessary color and decoration, and protects the base coat. During the production of topcoat, it needs to be ground. However, most grinding equipment is difficult to grind topcoat thoroughly, and the grinding of topcoat is either too simple or the contact area with topcoat is too small, resulting in insufficient grinding.

[0003] A search for the above-mentioned problems revealed that among the currently disclosed technologies, such as the raw material grinding device for producing acrylic polyurethane topcoat disclosed in CN217568874U, the topcoat is placed into a grinding box. First, the topcoat enters the cavity of the circular groove of the grinding box. The grinding block is rotated and installed in the circular groove. The material in the cavity is ground by the rotation of the grinding block. After grinding, the raw material falls through the discharge port onto the circular platform below. Then, the material on the circular platform is manually scraped into the grinding groove on the side. The side of the circular groove is equipped with a telescopic rod. The telescopic rod drives the grinding wheel to move down into the grinding groove and rotates it through a motor, thereby grinding the raw material in the grinding groove a second time.

[0004] However, after the first grinding is completed, when the raw material falls onto the lower circular platform, the grinding box may vibrate due to the operation of the motor, causing the material to deviate as it falls, making it difficult for it to fall completely onto the circular platform. Furthermore, the material may fall onto the telescopic rod or grinding wheel during its fall, resulting in some waste of the raw material. Utility Model Content

[0005] This invention proposes a graded circulating grinding device for topcoat, which solves the problem in related technologies where the paint may shift during the pouring process when grinding the paint for the second time, making it difficult for the paint to fall accurately onto the round table for secondary grinding.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-5 As shown in the figure, this embodiment proposes a graded circulating grinding device for topcoat, including a grinding box 1, connecting rods 2, a grinding container 3, a grinding assembly, a feeding assembly, a positioning assembly, and an abrasive assembly. The grinding box 1 has a feed inlet at its top. Two connecting rods 2 are provided, each fixedly installed on the inner wall of the grinding box 1. The grinding container 3 is disposed inside the grinding box 1 and fixedly installed between the two connecting rods 2. The grinding assembly is located at the top of the grinding box 1 for grinding the topcoat. The feeding assembly is mounted on the connecting rods 2, and the positioning assembly is mounted on the feeding assembly. The abrasive assembly is installed inside the grinding box 1 to perform secondary grinding of the topcoat. A feed cylinder 4 is fixedly installed at the feed inlet. The topcoat is placed into the grinding box 1 through the feed cylinder 4 and can be ground once by the grinding assembly. After grinding, the topcoat can be flowed onto the abrasive assembly through the feeding assembly and positioning assembly. The topcoat can be ground a second time by the abrasive assembly. After grinding, the topcoat can fall into the collection box 6 because a collection box 6 is slidably installed on the inner bottom wall of the grinding box 1 and the collection box 6 is located directly below the abrasive roller 403.

[0030] In this embodiment, reference Figure 2The grinding assembly includes a motor 101, a rotating shaft 102, and a grinding wheel 103. The motor 101 is mounted on the top of the grinding box 1, the rotating shaft 102 is fixedly mounted on the output end of the motor 101, and the grinding wheel 103 is fixedly mounted on the side of the rotating shaft 102.

[0031] In this embodiment, reference Figure 2 and Figure 3 The grinding assembly also includes a slide rail 104, a fixing plate 105, a scraper 106, and bolts 107. The slide rail 104 is fixedly installed on the side of the rotating shaft 102, and the fixing plate 105 is fixedly installed on the top of the slide rail 104. The fixing plate 105 has a threaded hole. The scraper 106 is slidably installed on the slide rail 104, and the top of the scraper 106 has a threaded hole. The bolts 107 are adapted to the threaded holes of the scraper 106 and the fixing plate 105. By starting the motor 101, the grinding wheel 103 is placed in the grinding box 1 and contacts the bottom of the grinding box 1. Therefore, the motor 101 drives the rotating shaft 102 and the grinding wheel 103 to rotate and grind in the grinding box 3. The slidable scraper 106 is in the grinding box 3, so that the paint in the grinding box 3 can be evenly spread and smoothed, making the grinding more uniform.

[0032] In this embodiment, reference Figure 4 The feeding assembly includes a connecting frame 201, a feeding rack 202, and a feeding plate 203. There are two connecting frames 201, which are fixedly installed on the inner side wall of the grinding box 1. The feeding rack 202 is fixedly installed between the two connecting frames 201. There are two feeding plates 203, which are inclined and fixedly installed on both sides of the feeding rack 202. After grinding, a valve 5 is connected to the bottom of the grinding box 3. When the valve 5 is opened, the topcoat falls through the feeding rack 202 onto the feeding plate 203. The feeding plate 203 is inclined, which allows the topcoat to slide into the feeding box 301.

[0033] In this embodiment, reference Figure 4 The positioning assembly includes a feeding box 301, support rods 302, and positioning plates 303. The feeding box 301 is fixedly installed between two feeding plates 203. There are two support rods 302, which are fixedly installed on the inner side wall of the grinding box 1, and the feeding box 301 is fixedly installed between the two support rods 302. The positioning plates 303 are arc-shaped, and there are two positioning plates 303, which are fixedly installed at the bottom of the feeding box 301. The topcoat can directly enter the two abrasive rollers 403 for grinding through the feeding box 301. If it falls onto the positioning plates 303, it can flow into the two abrasive rollers 403 through the arc-shaped positioning plates 303.

[0034] In this embodiment, reference Figure 5The abrasive assembly includes a support plate 401, a rotating shaft 402, an abrasive roller 403, and a power assembly. The support plate 401 is fixedly installed on the grinding box 1. There are four rotating shafts 402, which are arranged in pairs. Each pair of rotating shafts 402 is rotatably installed on the support plate 401 and the inner side wall of the grinding box 1. There are two abrasive rollers 403, which are fixedly installed between each pair of rotating shafts 402. The power assembly is located on the grinding box 1.

[0035] In this embodiment, reference Figure 5 The power assembly includes a gear 404 and a second motor 405. There are two gears 404, which are fixedly installed on one of the rotating shafts 402 in each group and mesh with each other. The second motor 405 is installed on the side of the grinding box 1, and the output end of the second motor 405 is fixedly connected to one of the rotating shafts 402. When the second motor 405 is started, the second motor 405 drives the rotating shaft 402 to rotate, which drives one of the gears 404 to rotate. The gear 404 drives the other gear 404 and the rotating shaft 402 to rotate, thereby driving the two abrasive rollers 403 to rotate, so as to grind the paint that falls between the two abrasive rollers 403.

[0036] In this embodiment, when grinding the topcoat, the topcoat is first fed into the grinding box 3 through the feed cylinder 4. Then, the motor 101 is started, which drives the rotating shaft 102 and the grinding wheel 103 to rotate and grind inside the grinding box 3. After the topcoat is poured into the grinding box 3, the slidable scraper 106 is moved away from the bottom of the grinding box 3. Then, the bolt 107 is threaded into the threaded holes of the fixing plate 105 and the scraper 106 to fix it. During rotation, the scraper 106 can evenly spread the topcoat in the grinding box 3, thus making it evenly ground. After grinding is completed, the scraper 106 can be slid to contact the bottom of the grinding box 3, thereby opening the valve 5 and allowing the topcoat to fall. During rotation, the scraper 106 can be driven to scrape the topcoat to the valve 5, so that... As the paint falls, it slides through the feeding plate 203 into the feeding box 301. It should be noted that the gap between the feeding box 301 and the two abrasive rollers 403 is in the same vertical position, and the two positioning plates 303 and the two abrasive rollers 403 are in the same vertical position, so that the falling paint can fall between the two abrasive rollers 403. Then, the second motor 405 is started, which drives the rotating shaft 402 to rotate. The rotating shaft 402 drives one of the gears 404 to rotate, and the gear 404 drives the other gear 404 meshing with it and the rotating shaft 402 to rotate, thereby driving the two abrasive rollers 403 to rotate, so as to grind the paint that has fallen between the two abrasive rollers 403. After grinding, it can fall directly into the collection box 6 for collection.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
