Description

Technical Field

[0001] The utility model relates to the technical field of high-adhesion waterborne coating production, in particular to a high-adhesion waterborne coating grinding device. Background Art

[0002] When producing plastic toys, it is necessary to coat the surface of the plastic toys with a coating to improve the aesthetics and wear resistance of the plastic toys. In order to ensure the adhesion of the coating to the substrate, make the coating layer more firm, and prevent peeling and cracking, high-adhesion waterborne coatings are often used.

[0003] When producing high-adhesion waterborne coatings, in order to ensure that the high-adhesion waterborne coatings can be evenly and continuously adhered to the surface of the substrate, a grinding device is used to grind the high-adhesion waterborne coatings to reduce the particle size in the high-adhesion waterborne coatings. Most of the existing grinding devices perform grinding operations by placing a grinding disc in a tank and contacting the materials at the bottom of the tank. However, the contact between the materials and the grinding disc in such an operation is limited, and because the materials are dissolved in water, as the grinding disc rotates, some materials will centrifuge and tend to move upward along the tank wall, making it difficult for the materials to come into full contact with the grinding disc, and thus resulting in a longer time required for the entire grinding process. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art and propose a high-adhesion waterborne coating grinding device.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: Design a high-adhesion waterborne coating grinding device, including a base.

The first external gear is coaxially installed on the first drive shaft, and a number of second external gears are engaged with the side surface of the first external gear.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Refer to Figures 1-4 , a high-adhesion water-based paint grinding device, including a base 1. A placement groove 3 is provided in the middle of the base 1, and the placement groove 3 penetrates through one side of the base 1, so that a paint bucket filled with paint to be ground can be placed in the placement groove 3; Self-locking universal wheels 2 are installed at the bottom corners of the base 1 to facilitate the movement of the base 1. During use, the base 1 can be pushed close to the paint bucket filled with paint to be ground, so that the paint bucket can be more conveniently placed in the placement groove 3.

[0025] As Figure 1 and Figure 3 shown, a cover plate 4 is provided above the placement groove 3. The cover plate 4 corresponds to the placement groove 3, that is, the cover plate 4 corresponds to the paint bucket placed in the placement groove 3. The top of the cover plate 4 is connected to a support seat 6 through a connecting seat 5. One end of the support seat 6 is arranged on the linear drive module 7, and the linear drive module 7 is fixed on the support frame 8, and the support frame 8 is fixed on the base 1. In the actual use process, the linear drive module 7 is one of a linear motor, an electric push rod, and a hydraulic cylinder. The linear drive module 7 is vertically arranged, so as to drive the cover plate 4 to rise and fall, thereby covering the cover plate 4 on the paint bucket filled with paint to be ground;

[0026] After the cover plate 4 is placed on the paint bucket filled with the paint to be ground, a first driving shaft 10 is installed at the center of the bottom of the cover plate 4. The first driving shaft 10 penetrates through the cover plate 4 and is connected to a driving motor 15. The driving motor 15 is fixed on the support base 6. The first driving shaft 10 is rotatably connected to the cover plate 4. A plurality of first support rods 16 arranged at intervals and with their ends bent in an "L" shape are provided on the side surface of the first driving shaft 10. The ends of the first support rods 16 are fixed on the first driving shaft 10. The first driving shaft 10 will extend into the paint bucket. In this way, after the first driving shaft 10 rotates, the first support rods 16 can stir the paint.

[0027] A number of second driving shafts 12 arranged at intervals are provided along the bottom edge of the cover plate 4. The second driving shafts 12 are rotatably connected to the cover plate 4. A number of second support rods 19 arranged at intervals and with their ends bent in an "L" shape are provided on the side surface of the second driving shafts 12. The ends of the second support rods 19 are fixed on the second driving shafts 12. And a number of second grinding blocks 20 arranged at intervals are installed on the side of the second support rods 19 away from the second driving shafts 12. Among them, a number of first grinding blocks 17 arranged at intervals are installed on the side of the first support rods 16 away from the first driving shaft 10. The first grinding blocks 17 are in clearance fit with the second grinding blocks 20 and are arranged staggeredly, so that the grinding blocks are arranged in a cylindrical shape in the paint bucket. In this way, more paint can come into contact with the grinding blocks, so as to perform better and more sufficient grinding operations during grinding.

[0028] Specifically, as Figure 4 shown, a cavity 9 is correspondingly opened in the cover plate 4. The top of the second driving shaft 12 penetrates into the cavity 9. And a first external gear 11 is provided in the middle of the cavity 9. The first external gear 11 is coaxially installed on the first driving shaft 10. And a number of second external gears 13 are meshed on the side surface of the first external gear 11. The second external gears 13 are coaxially installed on the second driving shafts 12. When the driving motor 15 drives the first driving shaft 10 to rotate, the meshing between the external gears can make the second driving shafts 12 also rotate self - sufficiently. It can not only stir the paint in the paint bucket, but also make the first grinding blocks 17 and the second grinding blocks 20 rotate alternately continuously, so as to grind the paint located between the first grinding blocks 17 and the second grinding blocks 20. In the actual use process, the radius of the first external gear 11 and the radius of the second external gear 13 are different, that is, the number of teeth of the first external gear 11 and the second external gear 13 are different. Optimally, the number of teeth of the second external gear 13 is greater than that of the first external gear 11, so that there is a speed difference between the first driving shaft 10 and the second driving shaft 12. In this way, the grinding blocks can rotate alternately at a higher frequency, so as to further improve the grinding efficiency.

[0029] Furthermore, as Figure 1 and Figure 3As shown, a spiral blade 18 is installed at the bottom of the first drive shaft 10. As the grinding continues, the spiral blade 18 will also rotate with the first drive shaft 10, so that the paint at the bottom of the paint bucket can be conveyed upward, thereby preventing particles from depositing at the bottom of the paint bucket and causing insufficient grinding.

[0030] Furthermore, as Figure 4 shown, an annular internal gear 14 is rotatably installed along the inner wall of the cavity 9. The internal gear 14 meshes with the second external gear 13. Since the specifications of the second external gears 13 are the same, while ensuring the normal self-rotation of the second external gear 13, support is provided for the rotation of the second external gear 13.

[0031] It should be noted that after the cover plate 4 is covered on the paint bucket, a baffle 21 is installed along the bottom edge of the cover plate 4. At this time, the baffle 21 will wrap around the periphery of the paint bucket, thereby preventing the paint from splashing out of the paint bucket after the support rod rotates.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
