Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating mixing technology, specifically to a coating mixing and stirring device. Background Technology
[0002] In the field of coating technology, a coating is defined as a continuous thin film that can firmly adhere to the surface of an object being coated. It mainly consists of resins, oils, or emulsions, with the addition of pigments and fillers, as well as appropriate additives, and is formulated with organic solvents or water to form a viscous liquid state. Before application, it is essential to ensure that the coating is thoroughly mixed; insufficient mixing will negatively impact the quality of the coating.
[0003] In the implementation of the embodiments of this disclosure, we have discovered at least the following problems in the field of coating technology: Currently, many large enterprises commonly use automated mixing devices to mix coatings; however, this approach is accompanied by high production costs and large space occupation, and the equipment structure is also relatively complex. In contrast, many small and medium-sized enterprises still rely on manual vertical stirring methods, inserting the stirring device into the mixing tank for mixing. The mixing effect of this method is not ideal, easily leading to coating accumulation at the bottom of the container and the formation of lumps. In addition, during the stirring process, coating may splash out from the tank opening, which not only affects the working environment but may also pose safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide a mixing and stirring device for coatings to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating mixing and stirring device, comprising a support frame and a mixing box rotatably mounted thereon. The support frame consists of a first longitudinal frame and a second longitudinal frame, which are respectively located on the left and right sides of the mixing box. A driven shaft is rotatably mounted on the first longitudinal frame and fixedly connected to the mixing box. A reduction gearbox is mounted on the second longitudinal frame. A first drive motor is mounted at the power input end of the reduction gearbox, and a gear transmission mechanism is mounted at the power output end of the reduction gearbox. A drive shaft is mounted at the output end of the gear transmission mechanism and connected to the bottom of the mixing box. Two spiral stirring paddles are mounted inside the mixing box and are arranged vertically. The spiral stirring paddles are driven by a second drive motor.
[0006] Preferably, a reinforcing rod is provided between the first longitudinal frame and the second longitudinal frame, and a reinforcing rib is provided at the connection between the reinforcing rod and the first longitudinal frame and the second longitudinal frame.
[0007] Preferably, the mixing tank is provided with a feeding door on its side wall, and the feeding door is provided with a handle.
[0008] Preferably, the upper end of the gear transmission mechanism is provided with a helical locking plunger, which is fixedly disposed at the upper end of the gearbox.
[0009] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a gear transmission mechanism and a reduction gearbox to drive the mixing tank to rotate, combined with a spiral stirring paddle installed inside the mixing tank, to achieve all-round and multi-angle mixing of the coating. This design overcomes the problem of coating clumping at the bottom of the container that is easily formed in traditional vertical stirring methods, ensuring the uniformity of coating mixing and thus improving the quality of the coating.
[0010] The device features a reasonable structural design and is easy to operate. The mixing tank rotates in a closed state, effectively preventing paint from splashing out of the tank opening during mixing, improving the working environment and reducing safety hazards. Additionally, a handle is provided on the feeding door for safe and convenient opening and feeding when needed.
[0011] Compared to automated mixing devices used by large enterprises, the mixing device of this invention has lower costs, a simpler structure, and is easier to maintain and service. Furthermore, it occupies a small area, making it suitable for use by small and medium-sized enterprises in limited production spaces, thus reducing production costs and space requirements.
[0012] By installing reinforcing rods and ribs between the first and second longitudinal frames, the stability of the support frame is enhanced, making the entire mixing device more stable and reliable during operation. Furthermore, the design of the spiral locking plunger improves the connection stability of the gear transmission mechanism, extending the service life of the equipment.
[0013] In summary, the coating mixing device provided by this utility model exhibits significant advantages in terms of mixing effect, operational safety, cost and space occupation, and structural stability, providing an efficient and economical mixing solution for small and medium-sized enterprises in the coating industry.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1 This utility model provides a technical solution: a coating mixing and stirring device, which includes a support frame 1 on which a rotatable mixing tank 2 is mounted. The support frame 1 consists of two longitudinal frames, namely a first longitudinal frame and a second longitudinal frame located on the left and right sides of the mixing tank 2. A driven shaft 3 is rotatably mounted on the first longitudinal frame and is fixedly connected to the mixing tank 2. A reduction gearbox 4 is mounted on the second longitudinal frame. The power input end of the reduction gearbox 4 is connected to a first drive motor 5, and its power output end is connected to a gear transmission mechanism 6. The output end of the gear transmission mechanism is connected to a drive shaft 7, which is connected to the bottom of the mixing tank 2. The mixing tank 2 is equipped with two spiral stirring paddles 11, which are arranged vertically and are driven by a second drive motor 12.
[0018] Specifically, to further enhance the stability and reliability of the entire device, the designers added a reinforcing rod 8 between the first and second longitudinal frames. This reinforcing rod 8 not only connects the two longitudinal frames but also adds reinforcing ribs at its connection with the first and second longitudinal frames. The presence of these reinforcing ribs further improves the strength and stability of the entire device structure, ensuring stable performance during long-term operation.
[0019] Furthermore, to facilitate the addition of coatings or other materials during the mixing process, a feeding door 9 was thoughtfully designed on the side wall of the mixing tank 2. This feeding door 9 not only allows users to easily add the required materials at any time during mixing but also considers user convenience. To further enhance user ease of operation, a handle 10 was specially designed on the feeding door 9. This handle 10 makes opening and closing the feeding door 9 easier and less strenuous, greatly improving user convenience. Through these detailed design features, the entire device has not only improved performance but also optimized the user experience.
[0020] To further improve the mixing effect, two spiral agitators 11 are installed inside the mixing chamber 2, arranged vertically. These two spiral agitators 11 are driven by a second drive motor 12, ensuring efficient and uniform mixing. Finally, to ensure the stability and reliability of the gear transmission mechanism 6, a spiral locking plunger 13 is added to its upper end. This plunger is fixedly installed at the upper end of the reduction gearbox 4, thereby ensuring the stable operation of the entire transmission system.
[0021] This design utilizes a gear transmission mechanism 6 and a reduction gearbox 4 to drive the mixing tank 2 to rotate. Combined with the spiral stirring paddle 11 installed inside the mixing tank 2, it achieves all-round, multi-angle mixing of the coating. This design effectively overcomes the problem of coating clumping at the bottom of the container, which is common in traditional vertical mixing methods, ensuring the uniformity of coating mixing and thus improving the quality of the coating.
[0022] Working Principle: During operation, the core drive system of this device consists of a first drive motor 5, a reduction gearbox 4, and a gear transmission mechanism 6. The first drive motor 5, after being reduced in speed by the reduction gearbox 4, transmits power to the gear transmission mechanism 6. The reduction gearbox 4 is designed to reduce the motor's output speed and increase torque to accommodate the greater force required during the stirring process.
[0023] The gear transmission mechanism 6 converts the output power of the reduction gearbox 4 into rotational motion, and transmits this rotational motion to the mixing tank 2 through the drive shaft 7.
[0024] The mixing tank 2 is connected to the first longitudinal frame via the driven shaft 3 and to the gear transmission mechanism 6 via the drive shaft 7. When the gear transmission mechanism 6 rotates, the drive shaft 7 drives the mixing tank 2 to rotate.
[0025] This rotary design overcomes the problem of paint clumping at the bottom of the container, which is common with traditional vertical mixing methods. The rotation of the mixing tank causes the paint to constantly change position within the tank, thus achieving all-around mixing.
[0026] The mixing tank 2 is equipped with spiral agitators 11, which are driven by an additional second drive motor 12. The design of the spiral agitators enables the coating to generate strong vortices and shear forces during the mixing process, further promoting the mixing of the coating.
[0027] There are two agitators arranged one above the other, which ensures that the coating in the mixing tank is fully mixed at all levels.
[0028] A reinforcing bar 8 and reinforcing ribs are provided between the first and second longitudinal frames. These structural elements improve the stability and durability of the device.
[0029] A feeding door 9 is provided on the side wall of the mixing tank 2 to facilitate the addition of coatings into the mixing tank. A handle 10 is provided on the feeding door 9 to make operation more convenient.
[0030] The upper end of the gear transmission mechanism 6 is provided with a spiral locking plunger 13, which is used to fix the connection between the gear transmission mechanism and the reduction gearbox 4, so as to ensure the stability and reliability of the transmission.
[0031] In summary, this coating mixing device achieves comprehensive, multi-angle mixing of the coating through the synergistic action of a rotary mixing tank and a spiral mixing blade. This design not only improves the mixing uniformity of the coating but also ensures its high quality. Furthermore, the device features a rational structural design, is easy to operate, and possesses high practicality and application value.
