Description

Technical Field

[0001] This utility model relates to the field of paint spraying and mixing technology, and more specifically, to a raw material mixing device for water-based paint spraying. Background Technology

[0002] In the production and preparation of many coatings (such as putty powder, self-leveling coatings, etc.), the raw materials need to be transported to the top of the mixing tank in proportion and put into it, and then mixed and stirred.

[0003] Because existing mixed coatings use different raw materials with varying viscosity and solidity, multiple layers may appear during the mixing process, leading to a decrease in mixing speed. Furthermore, existing raw material mixing equipment is difficult to clean after mixing, and the raw materials remaining inside the mixing equipment not only waste resources but also require time-consuming and labor-intensive manual cleaning. Utility Model Content

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. This utility model utilizes a mixing rod, a scraper, a guide rod, and a guide plate. The curved mixing rod can mix and stir water-based coating raw materials of different layers. The scraper can clean the inner wall of the mixing tank when rotating and drive the raw materials downward according to the tilt direction. The guide rod can stir the raw materials at the bottom of the mixing tank to prevent the raw materials from sticking or settling at the bottom. The guide plate can drive the raw materials at the bottom to move upward in a spiral to avoid multi-layer phenomenon. This solves the problem of multi-layer phenomenon that occurs during the mixing process, which leads to a decrease in mixing speed.

[0018] 2. This utility model uses a scraper and a guide rod. The scraper can clean the raw materials adhering to the inner wall of the mixing tank, and the guide rod squeezes the raw materials to the discharge port when it rotates, thus avoiding the problem that the raw materials remaining inside the mixing equipment not only waste resources, but also require time and effort to clean manually.

[0029] Please see Figure 1-5 This utility model provides a technical solution:

[0030] A raw material mixing device for water-based coating spraying includes a mixing tank 1, a pouring tank 2, support legs 3, an output motor 4, a mixing mechanism 5, a filter screen 6, and a sealing mechanism 7. The pouring tank 2 is installed on the top of the mixing tank 1, the support legs 3 are distributed at the four corners of the bottom of the mixing tank 1, the output motor 4 is installed at the bottom of the mixing tank 1, and the output end of the output motor 4 is used in conjunction with the mixing mechanism 5. The filter screen 6 is installed on the top inside the mixing tank 1, and the mixing tank 1 has a discharge port inside. The sealing mechanism 7 is sleeved on the surface of the discharge port.

[0031] The mixing mechanism 5 includes a main rod 51, a mixing rod 52, a scraper 53, a guide rod 54, a crushing rod 55, and a guide plate 56. The bottom end of the main rod 51 is fixedly connected to the output end of the output motor 4. There are multiple mixing rods 52, and the multiple mixing rods 52 are distributed in three pairs around the mixing rods 52. One end of the mixing rod 52 is fixedly connected to the side of the main rod 51, and the other end of the mixing rod 52 is fixedly connected to the side of the scraper 53. The end of the scraper 53 away from the mixing rod 52 contacts the inner wall of the mixing tank 1. One end of the guide rod 54 is fixedly connected to the side of the main rod 51, and the other end of the guide rod 54 contacts the side of the mixing tank 1. The left side of the crushing rod 55 is connected to the right side of the main rod 51. The bottom end of the crushing rod 55 contacts the surface of the filter screen 6. The guide plate 56 is sleeved on the surface of the main rod 51.

[0032] Specifically, the mixing rod 52 is curved, the end of the scraper 53 that contacts the mixing rod 52 is inclined, and the bottom end of the scraper 53 is located in front of the top end of the scraper 53. The curved shape drives the raw materials of different layers to mix.

[0033] Furthermore, the guide rod 54 is arc-shaped, and the bottom of the guide rod 54 contacts the bottom of the mixing tank 1. When the guide rod 54 is in operation, it drives the raw material to flow to the outside of the mixing tank 1.

[0034] It is worth noting that the filter screen 6 is arc-shaped, and the bottom end of the rolling rod 55 contacts the arc-shaped surface, which allows the water-based coating to concentrate at the top edge of the filter screen 6.

[0035] It is worth noting that the guide plate 56 is spirally coiled on the surface of the main rod 51, and the spiral drives the water-based coating at the bottom to move upward, so that the raw materials inside the mixing tank 1 are mixed.

[0036] In addition, the sealing mechanism 7 includes a sleeve 71, an insert block 72, a bracket 73, a screw 74, and a rotating wheel 75. The sleeve 71 is fitted onto the surface of the discharge port, the insert block 72 is embedded inside the discharge port, the rear side of the sleeve 71 is fixedly connected to the front side of the insert block 72, the bracket 73 is fixedly connected to the bottom of the sleeve 71, and the screw 74 is fitted onto the surface of the bracket 73 and engaged with it. One end of the screw 74 contacts the bottom of the discharge port, and the other end of the screw 74 extends through to the outside of the bracket 73 and is fixedly connected to the rotating wheel 75, thus sealing the discharge port and preventing material leakage.

[0037] It must be said that the mixing tank 1 and the pouring tank 2 are fixedly installed with bolts and nuts to achieve the installation between the mixing tank 1 and the pouring tank 2. When cleaning, the pouring tank 2 is opened to clean the filter screen 6.

[0038] Working principle: The user pours water-based paint raw materials into the pouring tank 2. Various raw materials enter the top of the filter screen 6. Some larger solid particles are intercepted, while smaller ones flow through the filter screen 6 into the mixing tank 1. Then, the output motor 4 is started. The output end of the output motor 4 drives the main rod 51 to rotate. The rotation of the main rod 51 drives the mixing rod 52, the guide rod 54, the crushing rod 55, and the guide plate 56 to rotate. The rotation of the mixing rod 52 drives the scraper 53 to rotate. The mixing rod 52 stirs the inside, the scraper 53 cleans the paint adhering to the inner wall, and the guide rod 54 stirs the raw materials at the bottom to prevent them from sticking to the bottom. While stirring, the raw materials are guided to the outside. The crushing rod 55 crushes the solid raw materials as the main rod 51 rotates, causing the solid raw materials to break down and flow from the filter screen 6 into the mixing tank 1. Inside, the guide plate 56 guides the bottom material to the top, accelerating the mixing of the bottom and top materials. After mixing, the user does not need to turn off the output motor 4. The user rotates the screw 74 through the rotating wheel 75 to disengage the screw 74 from the discharge port. Then, the user pulls the sealing mechanism 7 out of the discharge port. After pulling it out, the material inside the mixing tank 1 flows out of the discharge port. As most of the material inside the mixing tank 1 flows out, some material will stick to the inside. The scraper 53 and the guide rod 54 will discharge the residual material on the inner wall of the mixing tank 1 from the discharge port. After the material inside is discharged, the user removes the bolts and nuts to disassemble the pouring tank 2. Then, the filter screen 6 is rinsed with water to clean it. After cleaning, the pouring tank 2 is installed with the bolts and nuts to complete the operation.
