Description

Two-way blade paddle-type epoxy flooring material mixing device Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically to a two-way blade paddle-type epoxy flooring material mixing device. Background Technology

[0002] Epoxy flooring materials are widely used in industrial plants, commercial spaces, and other settings due to their excellent wear resistance, chemical corrosion resistance, and ease of application. The material typically consists of an epoxy resin base (containing resin, fillers, pigments, additives, etc.) and a curing agent. A mixing device is required to ensure uniform mixing of the multiple components, guaranteeing the mechanical strength, surface smoothness, and service life of the floor coating.

[0003] Among various mixing equipment, paddle mixers have become the mainstream choice for small and medium-sized epoxy flooring construction (such as on-site operations with a single mixing volume of ≤50L) due to their simple structure, low manufacturing cost, convenient maintenance, and strong adaptability to container shapes. Compared with high-performance mixing devices such as turbine and planetary mixers, paddle mixers are suitable for outdoor construction scenarios with frequent relocation due to their low equipment cost and portable operation.

[0004] However, traditional paddle mixers, due to their flat blades, can only generate axial flow and lack radial shear force for particulate fillers with large density differences. This results in the inability to effectively break up agglomerates, often leading to bottom sedimentation and uneven coloring of the mixed material. This negatively impacts the mechanical properties of the final floor coating. Furthermore, the rotation of the flat blades easily causes swirling, resulting in the material only undergoing circular motion without turbulent mixing, necessitating extended mixing time to ensure thorough mixing.

[0005] In the prior art, such as the inclined paddle mixer with shear blades disclosed in Chinese patent application number 202420185790.4, a paddle blade with serrated blades is provided, which can generate turbulence and improve the mixing effect when rotating. However, compared with straight blades, it will generate greater resistance when rotating. If it is used directly as the paddle blade, the energy consumption is high and the production cost is high in the initial macroscopic mixing stage of materials. Summary of the Invention

[0006] To address the aforementioned technical problems, the bidirectional blade paddle-type epoxy flooring material mixing device provided by this utility model can improve mixing efficiency and reduce energy consumption through bidirectional blade and forward / reverse rotation control.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model provides a bidirectional paddle-type epoxy flooring material mixing device, including a stirring shaft, a drive mechanism, multiple paddle blades, and a mixing container.

The drive mechanism is fixed to the mixing container. The mixing container has a cavity. The stirring shaft extends into the cavity. The paddle blades are fixed to the stirring shaft. The paddle blades are located within the cavity. The paddle blades have a flat plate structure. The two sides of the paddle blades are respectively a straight pushing blade and a serrated dispersing blade. The straight pushing blade is linear. The serrated dispersing blade is provided with several spaced serrations. When the stirring shaft rotates clockwise, the straight pushing blade moves toward and separates the material. When the stirring shaft rotates counterclockwise, the serrated dispersing blade moves toward and separates the material.

[0009] The bidirectional blade-type epoxy flooring material mixing device provided by this utility model preferably has 2 to 4 blades; the blades are evenly distributed circumferentially along the axis of the stirring shaft; and the straight thrust blades of each blade face the same direction in the direction of rotation of the stirring shaft.

[0017] Example 1:

[0018] The bidirectional paddle-type epoxy flooring material mixing device provided in Embodiment 1 of this utility model, as shown in Figures 1 and 2, includes a stirring shaft 1, a drive mechanism 2, multiple paddle blades 3, and a mixing container 4. The stirring shaft 1 is fixed on the drive mechanism 2. The drive mechanism 2 can drive the stirring shaft 1 to rotate clockwise or counterclockwise along the axis of the stirring shaft 1. The drive mechanism 2 is fixed on the mixing container 4. The mixing container 4 has a cavity 41. The stirring shaft 1 extends into the cavity 41. The paddle blades 3 are fixed on the stirring shaft 1. The paddle blades 3 are located inside the cavity 41. The paddle blades 3 have a flat plate structure. The two sides of the paddle blades 3 are respectively a straight pushing blade 31 and a serrated dispersing blade 32. The straight pushing blade 31 is straight. The serrated dispersing blade 32 is provided with a number of serrated teeth 321 distributed at intervals. When the stirring shaft 1 rotates clockwise, the straight pushing blade 31 moves toward and separates the material. When the stirring shaft 1 rotates counterclockwise, the serrated dispersing blade 32 moves toward and separates the material.

[0019] The bidirectional blade-type epoxy flooring material mixing device provided in Embodiment 1 of this utility model involves feeding materials into the cavity 41 of the mixing container 4. The driving mechanism 2 drives the stirring shaft 1 to rotate, thereby causing the paddle blades 3 to move within the cavity 41. The paddle blades 3 move different materials within the cavity 41, thus achieving mixing of different materials. Unlike existing technologies, in this embodiment, the driving mechanism 2 can drive the stirring shaft 1 to rotate clockwise and counterclockwise. During clockwise rotation, the stirring shaft 1 rotates clockwise, and the straight, propelling blades 31 of the paddle blades 3 break through the liquid material, causing the paddle blades 3 to move. With low resistance, the material can be quickly mixed in the cavity 41. After rotating forward for a certain period of time, the drive mechanism 2 reverses, and the stirring shaft 1 rotates counterclockwise, driving the serrated dispersing blades 32 of the paddle blades 3 to break the liquid material. After the serrations 321 on the serrated dispersing blades 32 come into contact with the material, they can drive the material to move in different directions, thereby forming turbulence and improving the mixing effect between the materials. Therefore, this embodiment can use forward rotation with lower energy consumption in the initial mixing and reverse rotation with better mixing effect in the later mixing, thus ensuring mixing efficiency while saving energy.

[0020] The bidirectional blade paddle-type epoxy flooring material mixing device provided in Embodiment 1 of this utility model addresses the problem of high energy consumption in existing paddle mixers by improving mixing efficiency and reducing energy consumption through bidirectional blade and forward / reverse rotation control.

[0021] To achieve different effects when the stirring shaft 1 rotates forward and backward, in this embodiment, the number of paddle blades 3 is 2 to 4; the paddle blades 3 are evenly distributed circumferentially along the axis of the stirring shaft 1; in the direction of rotation of the stirring shaft 1, the orientation of the straight propulsion blades 31 of each paddle blade 3 is consistent. When the stirring shaft 1 rotates forward, all paddle blades 3 are first in contact with the material in front (in the direction of movement of the paddle blades 3) by the straight propulsion blades 31; when the stirring shaft 1 rotates backward, all paddle blades 3 are first in contact with the material in front by the serrated dispersing blades 32.

[0022] As a preferred embodiment, in this embodiment, the drive mechanism 2 includes a motor 21 and a frequency converter; the output shaft of the motor 21 is connected to the stirring shaft 1 via a transmission; the frequency converter can control the speed and direction of the output shaft of the motor 21. The electrical connection between the frequency converter and the motor 21 is existing technology and will not be described in detail here. Operators can control the rotation direction and speed of the motor 21 by controlling the frequency converter, thereby realizing the direction and speed control of the stirring shaft 1.

[0023] As a preferred embodiment, in this embodiment, the inner wall of the cavity 41 is provided with an anti-stick coating; the bottom of the cavity 41 is conical; the stirring shaft 1 is vertical; and the stirring shaft 1 is disposed on the conical axis of the cavity 41. The purpose of the anti-stick coating is to make the cavity 41 easy to clean and reduce the residue after material discharge; the conical bottom is coaxial with the stirring shaft, which can guide the material to converge towards the center, and achieve mixing without dead corners in conjunction with stirring, thereby improving the uniformity of the material after stirring.

[0024] As a preferred embodiment, in this embodiment, the apex angle of the serration 321 is 30° to 60°; the dimension of the serration 321 perpendicular to the extension direction of the paddle blade 3 is the height of the serration 321; the distance between the straight flow-pushing blade 31 and the dispersing blade of the serration 321 is the width of the paddle blade 3; the height of the serration 321 is 1 / 10 to 1 / 5 of the width of the paddle blade 3. The geometric parameters of the serration 321 are the preferred solution in this embodiment, with the aim of ensuring that the shear force and turbulence intensity are adapted to the properties of the epoxy material while improving the dispersion efficiency and avoiding excessive wear of the serration 321.

[0025] In summary, this utility model provides a bidirectional paddle-type epoxy flooring material mixing device, relating to the technical field of mixing devices. It includes a mixing shaft, a drive mechanism, multiple paddle blades, and a mixing container. The mixing shaft is fixed to the drive mechanism. The drive mechanism can drive the mixing shaft to rotate clockwise or counterclockwise along the axis of the mixing shaft. The drive mechanism is fixed to the mixing container. The mixing container has a cavity. The mixing shaft extends into the cavity. The paddle blades are fixed to the mixing shaft. The paddle blades are located within the cavity. The paddle blades have a flat plate structure. The two sides of the paddle blades are respectively a straight pushing blade and a serrated dispersing blade. The straight pushing blade is linear. The serrated dispersing blade has several spaced serrations. When the mixing shaft rotates clockwise, the straight pushing blade moves towards and separates the material. When the mixing shaft rotates counterclockwise, the serrated dispersing blade moves towards and separates the material.
