Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a coating mixing machine. Background Technology

[0002] In the field of paint production, traditional paint mixing equipment has many limitations. Taking the paint mixer mentioned in the above reference case as an example, although it uses a drive motor to drive the stirring rod and stirring plate to mix the paint, the mixing method is relatively simple. Although the adjustment device under the stirring plate takes into account the adaptability to some extent, it still has obvious shortcomings in terms of the uniformity and efficiency of paint mixing.

[0003] Publication No. CN219849064U discloses a paint mixer, specifically relating to the paint production field. This application includes a mixer body and a paint tank. A drive motor is mounted on the surface of the mixer body, and a stirring rod is fixedly installed at the output end of the drive motor. A stirring disc is fixedly installed at the lower end of the stirring rod, and the stirring disc is located inside the paint tank. An adjustment device is provided on the lower surface of the stirring disc, comprising several sliding seats. The upper surface of each sliding seat is fixedly connected to the stirring disc, and a stirring plate is inserted inside the sliding seat. A rotating seat is fixedly connected to the center of the lower surface of the stirring disc, and a rotating rod is rotatably connected to the inner wall of the rotating seat. This application achieves the effect of improving the adaptability of the mixer and thus better mixing of paints by allowing the operator to adjust the exposed length of the stirring plate according to the specifications of the paint tank due to the adjustment device.

[0004] The above-mentioned problems still exist, specifically: On the one hand, the mixing components are often concentrated in the mixing pan area, which cannot achieve full mixing of the paint in the paint bucket from all directions and angles. This can easily lead to uneven mixing of paint components. Especially for some paint formulations containing multiple additives and requiring extremely high mixing uniformity, it is difficult to ensure the stability and consistency of product quality. This may cause problems such as uneven color and weak adhesion in actual use, affecting the final performance and market competitiveness of the paint. On the other hand, when facing the production process requirements of some special paints, such as some paints needing to be mixed and reacted in a specific temperature environment to achieve optimal chemical and physical properties, traditional mixers lack effective temperature control methods or the temperature control is uneven and inaccurate, which cannot meet the refined production needs of these special paints. This not only limits the expansion of paint product types, but also hinders enterprises from developing high-end and differentiated paint products, making it difficult to adapt to the increasingly diversified and high-quality market demands.

[0005] In view of this, we have studied and improved the existing structure and its shortcomings to provide a paint mixing machine that is more practical. Utility Model Content

[0032] Mixing tank 1:

[0033] The container is shaped like a container and is the main place for mixing coatings. Its internal space is used to hold coating raw materials, and the external structure is used to install and support other components. The interior is equipped with an inner tank 13, which forms a cavity with the inner wall of the mixing tank 1 to provide space for the installation of the electric heating ring 14, so as to realize the heating function of the coating and meet the temperature requirements of the specific coating mixing process.

[0034] Support leg 2:

[0035] Installed around the bottom of mixing tank 1, it serves to support and stabilize mixing tank 1, ensuring that the entire equipment is placed stably during operation and avoiding the impact of shaking or displacement on the coating mixing effect and the safety of the equipment.

[0036] Top cover 3:

[0037] It fits tightly against the upper end of the mixing tank 1 and is fixedly installed through the cooperation of the connector 8 and the mounting block 9, ensuring the sealing of the mixing tank 1 and preventing the paint from overflowing during the mixing process. At the same time, it provides an installation position for components such as the feed pipe 4.

[0038] Feed pipe 4:

[0039] Fixedly connected to one side of the upper end of the top cover 3, it serves as a channel for paint raw materials to enter the mixing tank 1. Operators can pour various paint raw materials into the mixing tank 1 in proportion through the feed pipe 4 to start the mixing process.

[0040] Water tank 5:

[0041] It is fixedly installed on the other side of the outer end of the mixing tank 1. A level gauge is set on one side of its outer end surface to monitor the water level in the water tank 5 in real time. There is a water injection tank 10 on one side of the upper end surface to facilitate the replenishment of water. A water pump 11 is installed in the center of the upper end and connected to the liquid delivery pipe 12.

[0042] Heating controller 6:

[0043] Installed on one side of the outer end surface of the mixing tank 1, and electrically connected to the electric heating ring 14, it is used to control the heating power and temperature of the electric heating ring 14. The operator can precisely adjust the working state of the electric heating ring 14 through the heating controller 6 according to the requirements of the coating mixing process, so that the coating can be mixed and reacted at a suitable temperature, ensuring the quality and performance stability of the coating.

[0044] Discharge pipe 7:

[0045] Fixedly connected to the lower end of the outer side of the mixing tank 1, it is the channel for discharging the mixed paint from the mixing tank 1. A rotary valve is fixedly installed at the outer end. By controlling the opening and closing of the rotary valve, the discharge can be controlled, making it convenient for operators to collect the paint into the corresponding container and complete the mixing and discharge process.

[0046] Connector 8 and mounting block 9:

[0047] The connector 8 is fixedly installed around the upper surface of the mixing tank 1, and the mounting block 9 is fixedly installed around the outer end of the top cover 3.

[0048] Water inlet tank 10:

[0049] Located on one side of the upper surface of water tank 5 is the inlet for replenishing water into water tank 5. When the water level in water tank 5 is insufficient, the operator can easily add water through the water filling tank 10 to ensure the normal water supply function of water tank 5 and meet the water demand during equipment operation.

[0050] Water pump 11 and infusion pipe 12:

[0051] The water pump 11 is installed at the center of the upper end of the water tank 5. The suction generated by its operation draws water out of the water tank 5 and delivers it to the designated location through the infusion pipe 12. The other end of the infusion pipe 12 is fixedly connected to the upper end of the top cover 3, which can introduce water into the mixing tank 1 to achieve functions such as cleaning the mixing tank 1, ensuring the cleanliness and normal operation of the equipment, and meeting the requirements of water vapor environment in some coating mixing processes.

[0052] Inner tank 13 and electric heating ring 14:

[0053] The inner tank 13 is placed inside the mixing tank 1, and the cavity formed by the inner wall of the mixing tank 1 is used to install the electric heating ring 14. The electric heating ring 14 is arranged around the center of the cavity. When the power is turned on, heat is generated. The heat is transferred to the coating inside the tank through the wall of the inner tank 13, so that the coating can be kept within a suitable temperature range during the stirring and mixing process, which meets the strict temperature requirements of some coating mixing processes, promotes better mixing reaction of coating components, and improves coating quality.

[0054] Rotating rod 15, stirring blade 16, driven gear disc 17, rotary motor 18, and drive gear disc 19:

[0055] Four rotating rods 15 are arranged around the inside of the mixing tank 1, with their lower ends extending into the bottom surface of the mixing tank 1 and fixedly mounted with driven gear discs 17. A rotary motor 18 is installed in the center of the bottom surface of the mixing tank 1, with its output end extending into the bottom surface of the mixing tank 1 and fixedly mounted with a drive gear disc 19. The drive gear disc 19 contacts and meshes with the outer ends of the four driven gear discs 17. When the rotary motor 18 is started, the drive gear disc 19 rotates, causing the four driven gear discs 17 to rotate synchronously, thereby causing the four rotating rods 15 to rotate around their own axis inside the mixing tank 1. The stirring blades 16 are fixedly mounted on both sides of the outer end of the rotating rods 15. As the rotating rods 15 rotate, the stirring blades 16 rotate rapidly, thoroughly mixing the coating in the mixing tank 1. The four sets of stirring components apply stirring force to the coating from multiple directions, ensuring that the various components of the coating can be fully integrated, achieving an efficient and uniform mixing effect, and improving the mixing quality and production efficiency of the coating.

[0056] Working principle: First, the mixing tank 1 is stably placed in a suitable working position using the support feet 2. The top cover 3 is fixedly engaged with several mounting blocks 9 around its outer perimeter and several connectors 8 around the upper surface of the mixing tank 1, ensuring a tight seal and preventing paint overflow during mixing. The operator pours the paint raw material into the mixing tank 1 through the feed pipe 4. Simultaneously, the water level in the water tank 5 can be observed through the level gauge on one side of the outer surface of the water tank 5. If the water level is insufficient, water can be added to the water tank 5 through the water filling tank 10 for subsequent replenishment. The system provides water for heating or other operations, and starts the rotary motor 18. The output of the rotary motor 18 drives the fixedly mounted drive gear disk 19 to rotate. Since the outer end of the drive gear disk 19 is in contact with and meshed with the outer ends of the driven gear disks 17 at the lower ends of the four rotating rods 15 arranged around the inside of the mixing tank 1, the rotation of the drive gear disk 19 will drive the four driven gear disks 17 to rotate synchronously, thereby causing the four rotating rods 15 to rotate around their own axis inside the mixing tank 1. As the rotating rods 15 rotate, the stirring blades 16 fixedly mounted on both sides of their outer ends also rotate rapidly. During the rotation, the stirring blades 16 will stir the mixing tank 1. The coating inside is thoroughly stirred and mixed. Because the stirring components are arranged in four groups, this multi-directional stirring ensures that the coating is subjected to stirring force in all directions, resulting in a more uniform and efficient mixing effect. This ensures that all components of the coating are fully integrated. When the mixing of the coating requires a certain temperature condition, the electric heating rings 14 can be activated via the heating controller 6. The mixing tank 1 has an inner tank 13 inside, which forms a cavity with the inner wall of the mixing tank 1. Several electric heating rings 14 are arranged around the center of the cavity. When the electric heating rings 14 are energized, they generate heat, which is transferred through the wall of the inner tank 13. The coating is fed into the tank to maintain a suitable temperature range during the mixing process. This helps some coating components to mix and react better, improving the quality and performance stability of the coating. Especially for coating formulations that require specific temperature conditions to achieve the best mixing effect, heating-assisted mixing is a very important step. After the coating is fully mixed in the mixing tank 1 to achieve the expected mixing effect, the rotary valve fixedly installed at the outer end of the discharge pipe 7 is opened, and the coating is discharged from the mixing tank 1 through the discharge pipe 7. The operator can collect the discharged coating into the corresponding container, completing the entire coating mixing and discharge process.
