Description

Technical Field

[0002] As is well known, coating dispersion equipment is a key piece of equipment used in coating production to uniformly disperse solid particles such as pigments and fillers into base materials (such as resins and solvents), break particle agglomeration, reduce particle size, and achieve system homogenization.

[0003] In existing paint dispersion devices used for paint production, the top opening of the tank is usually exposed to meet the lifting requirements because the height of the stirring components needs to be adjusted. However, this design has a drawback: the high-speed rotating stirring components will cause the paint to form a vortex, which can easily cause the paint to splash from the exposed opening, resulting in waste of raw materials, increased cleaning burden on the equipment and environment, and reduced production efficiency.

[0013] 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.

[0014] Please refer to Figures 1-4. A paint dispersion device for paint production includes a base plate 1, a support base 2, a sealing mechanism 3, and a stirring assembly 11. One end of the support base 2 is connected to the top of the base plate 1, and the other end is connected to the bottom of a housing 18. A discharge assembly is located at the center of the bottom of the housing 18. The sealing mechanism 3 includes a semi-circular plate 4, a connecting block 5, a telescopic cylinder 6, a T-shaped block 7, a T-slot 8, and a positioning block 9. One end of the telescopic cylinder 6 is connected to the top of the base plate 1, and the other end is connected to one end of the T-shaped block 7. One end of the connecting block 5 is connected to the semi-circular plate 4. The T-slot 8 is formed on the connecting block 5, and the other end of the T-shaped block 7 extends into the T-slot 8. The semi-circular plate 4 is located at the top of the housing 18, and a positioning slot is formed at the top of the housing 18. One end of the positioning block 9 is connected to the semi-circular plate 4. The other end extends into the positioning groove. There are two sealing mechanisms 3. The stirring assembly 11 includes a square plate 12, a motor 13, a transmission column 14, a dispersing disc 15, a handle 16, and a long rod 19. The motor 13 is located on the top of the square plate 12. The output end of the motor 13 is connected to the transmission column 14. The dispersing disc 15 is located at the bottom of the transmission column 14. The transmission column 14 passes through the semi-circular plate 4. The handle 16 is located on the top of the square plate 12. One end of the long rod 19 is connected to the bottom of the square plate 12, and the other end of the long rod 19 contacts the top of the semi-circular plate 4.

[0015] Working principle: As shown in Figure 1, the equipment is placed in the designated position and is stably supported by the alloy steel base plate 1. After the external mains power is connected to power the equipment, 17 simultaneously starts two telescopic cylinders 6, driving the semi-circular plate 4 to rise upward, so that the semi-circular plate 4 separates from the top of the box 18, forming a gap for raw material input. At this time, the staff needs to manually hold the semi-circular plate 4 to prevent the positioning block 9 from shifting after separating from the positioning groove on the top of the box 18. After the paint material to be dispersed is poured into the box 18 through the above-mentioned gap, the telescopic cylinder 6 is controlled to reset, so that the semi-circular plate 4 falls back to the top of the box 18: the positioning block 9 is re-embedded in the positioning groove, and the silicone sealing ring at the top of the box is pressed and tightly fitted to the bottom of the semi-circular plate 4; at the same time, the semi-circular holes of the two semi-circular plates 4 are joined to form a complete circular hole, and the sealing ring inside the hole is fitted to the outer wall of the transmission column 14. The double sealing design can effectively prevent paint from splashing during stirring. During the dispersion operation, the worker holds the handle 16 and starts the motor 13 on the square plate 12. The motor output drives the transmission column 14 to rotate, which in turn drives the dispersion disc 15 at the bottom to rotate at high speed. The serrated structure on the surface of the dispersion disc 15 can shear and crush the paint in the box 18 to achieve particle dispersion. By lifting the handle 16 up and down, the transmission column 14 and the dispersion disc 15 can be driven to rise and fall synchronously (the long rod 19 contacts the top of the semi-circular plate 4, which can limit the lowest descent position of the stirring component 11 and avoid the dispersion disc 15 from colliding with the bottom of the box 18), thereby uniformly stirring the materials at different heights in the box. It should be noted that the circular hole formed by the two semicircular plates 4 is adapted to the transmission column 14. The sealing ring inside the circular hole is made of wear-resistant elastic material (such as food-grade silicone). Its inner diameter is slightly smaller than the outer diameter of the transmission column 14. While ensuring a tight fit with the outer wall of the transmission column 14 to achieve a seal, it does not hinder the rotational movement of the transmission column 14. Moreover, the sealing ring has a certain elastic deformation space. When the transmission column 14 is raised and lowered by the handle 16, the sealing ring can adaptively adjust its fit with the movement of the transmission column 14, which maintains the sealing effect and does not affect the smoothness of the raising and lowering movement. In addition, when the transmission shaft rotates, high-temperature grease can be applied to the inner wall of the sealing ring in advance, which reduces the frictional wear between the sealing ring and the transmission column 14 and enhances the sealing performance. The mixing component 11 mentioned in the text is a small structure that can be easily handled by staff for extended periods. Staff need to hold the handle 16 while handling the mixing component 11, and two staff members can take turns handling it. The discharge component mentioned in the text uses a pneumatic butterfly valve, which is a common technology on the market and will not be described in detail here. After the work is completed, open the discharge component at the bottom of the box 18 to discharge the dispersed coating to the receiving equipment below. During the cleaning stage, start the telescopic cylinder 6 again through the controller 17 to lift the semi-circular plate 4, so that the positioning block 9 is disengaged from the positioning groove. One worker holds the handle 16 to fix the mixing component 11 to prevent it from falling accidentally. Another worker pushes the semi-circular plate 4 so that the T-shaped block 7 slides out along the T-shaped groove 8 of the connecting block 5. The semi-circular plate 4 can then be removed. After that, the mixing component 11 is separated from the box 18 so that it can be cleaned with external tools. This structure, through the symmetrically arranged sealing mechanism 3, not only seals the top of the box 18 and prevents paint splashing, but also ensures that the lifting and adjusting of the stirring assembly 11 is unobstructed through the sliding fit of the T-block and T-slot and the gap design between the semi-circular hole and the transmission column, thus balancing sealing performance and operational flexibility.

[0016] To facilitate real-time observation of the dispersion state of the coating inside the chamber 18 (such as the degree of particle breakage and the uniformity of material mixing), this embodiment adds an observation window 10 to the front of the chamber 18. The observation window 10 is made of high-transmittance, wear-resistant glass and is embedded in the reserved installation groove on the front of the chamber 18 through a sealing ring. This ensures both clear observation and a sealed fit with the chamber 18, preventing the coating from leaking through gaps during dispersion. At the same time, the installation height of the observation window 10 covers the main stirring area inside the chamber 18, allowing operators to intuitively grasp the dispersion progress of materials at different heights without moving equipment. This provides an accurate basis for adjusting stirring parameters (such as raising and lowering the dispersion plate 15 and controlling the stirring time), further improving the convenience of operation and the controllability of the dispersion effect.

[0017] To improve the convenience and accuracy of equipment operation, this embodiment integrates a controller 17 on the top of the base plate 1. The controller 17 is electrically connected to the two telescopic cylinders 6 via wires, enabling synchronous control of the telescopic cylinders 6. The controller 17 has clear operation buttons (such as up, down, and stop) and status indicator lights on its surface. Operators do not need to manually adjust individual cylinders; they can control the coordinated movement of the two telescopic cylinders 6 with a single button press through the controller. This ensures that the semicircular plate 4 remains horizontally synchronized during the lifting and lowering process, avoiding structural displacement or sealing failure caused by inconsistent movement of the cylinders on both sides. In addition, the controller 17 has a built-in overload protection module. When the telescopic cylinder 6 is obstructed (such as when the positioning block 9 is stuck), it can automatically cut off the power and trigger an alarm, which simplifies the operation process and provides a guarantee for the safe operation of the equipment.

[0018] To further improve the overall support stability of the equipment and avoid the displacement or shaking of the box 18 caused by vibration generated during dispersion operations, the layout of the support base 2 has been optimized in this embodiment. Several support bases 2 are set along the connection surface between the bottom plate 1 and the box 18, and all support bases 2 are symmetrically distributed (e.g., evenly distributed on both sides with the central axis of the box 18 as the axis of symmetry). This symmetrical layout can evenly distribute the gravity load of the box 18 and the internal materials to each support point of the bottom plate 1, effectively balancing the reaction force generated by the high-speed rotation of the stirring component 11 during dispersion, preventing the bottom plate 1 from tilting or the support base 2 from deforming due to excessive force on one side. At the same time, the connection between the support base 2 and the bottom plate 1 and the box 18 adopts a reinforced welding process, which further enhances the structural rigidity and provides a stable support foundation for the box 18, ensuring the smooth operation of the equipment throughout the dispersion operation.

[0019] To further improve the engagement stability and sealing reliability of the sealing mechanism, this embodiment optimizes the fit precision of the positioning block 9 and the positioning groove. The two adopt perfectly matched structural dimensions and shapes. Specifically, the cross-sectional profile of the positioning block 9 (such as rectangle, trapezoid, etc.) is perfectly matched with the inner cavity shape of the positioning groove, and the outer diameter of the positioning block 9 is slightly smaller than the inner diameter of the positioning groove (leaving a small assembly gap to ensure smooth insertion). This precise matching design enables the positioning block 9 to form a tight mechanical engagement after being inserted into the positioning groove, effectively limiting the horizontal displacement of the semi-circular plate 4 and preventing loosening of the engagement due to vibration during dispersed operations. At the same time, the silicone sealing ring embedded in the positioning groove is pressed by the positioning block 9. The tight fit between the two further enhances the sealing effect and prevents the coating from leaking from the gaps. Thus, while improving the engagement stability, the sealing performance of the sealing mechanism is also taken into account.

[0020] To further enhance the structural strength and load-bearing capacity of the base plate 1, ensuring its stable support for the upper support base 2, the housing 18, and the entire dispersion mechanism (including the dynamic load generated during the operation of the stirring assembly 11), in this embodiment, the base plate 1 is specifically made of alloy steel. Due to its high strength and high toughness, alloy steel can not only withstand the overall weight of the equipment and the vibration and impact forces during dispersion operations, but also effectively resist deformation or bending that may occur during long-term use. This avoids problems such as tilting of the support base 2 and shaking of the housing 18 caused by deformation of the base plate 1. Furthermore, alloy steel has excellent fatigue resistance, adapting to frequent start-stop operations and long-term high-intensity operation scenarios, providing a solid foundation for the overall structural stability of the equipment and extending its service life.
