Description

Technical Field

[0001] The utility model belongs to the technical field of coating production equipment, and particularly relates to a stirring device for water-based coating production. Background Art

[0002] Water-based paints, due to their environmentally friendly and pollution-free properties, are widely used in a variety of fields, including construction, automotive, and home furnishings. Stirring is a key step in the production of water-based paints, ensuring uniform distribution of the paint's components and ensuring its quality and effectiveness. While various stirring devices exist, several technical challenges remain in their practical application.

[0003] Currently, most common water-based paint stirring devices use a single stirring mechanism, which fails to fully mix the paint and easily leads to localized accumulation of paint inside the tank, affecting the uniformity of the paint. Furthermore, traditional stirring devices tend to generate large shear forces during the stirring process, which may damage certain components in the paint and affect the paint's performance. To overcome these problems, there is an urgent need for a stirring device for water-based paint production that can effectively improve stirring efficiency and ensure stirring uniformity. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a stirring device for water-based paint production, which can effectively solve the problems of uneven stirring and low efficiency in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A stirring device for producing water-based paint, comprising a tank body, a motor frame provided on the top of the tank body, a motor provided on the top of the motor frame, an output end of the motor connected to a central shaft, and a spiral blade fixedly connected to the outer side surface of the bottom of the central shaft;

[0007] The central shaft is connected to a direction-changing mechanism;

[0008] The direction-changing mechanism includes a fixed tooth fixedly connected to the central shaft, and a linkage tooth rotatably connected to the central shaft, and a driven tooth meshed between the fixed tooth and the linkage tooth;

[0009] The bottom of the linkage teeth is connected with a stirring assembly.

[0010] Furthermore, the stirring assembly includes a top plate and a bottom plate sleeved on the central axis, and a second positioning shaft is inserted between the two ends of the top plate and the bottom plate, and the second positioning shaft is sleeved with a stirring blade.

[0011] Furthermore, the cross section of the stirring blade is configured to be drop-shaped, and disturbance plates are fixedly connected to both sides of the stirring blade at equal intervals along the height direction thereof.

[0012] Furthermore, a third through hole is formed through one end of the stirring blade, and the second positioning shaft passes through the third through hole.

[0013] Furthermore, a first through hole is opened through the top center of the top plate, a second through hole is opened through the top center of the bottom plate, and the first through hole and the second through hole are coaxially arranged, and the central axis passes through the first through hole and the second through hole.

[0014] Furthermore, the top of the top plate is symmetrically fixedly connected with a threaded column;

[0015] A positioning hole corresponding to the threaded column is formed through the upper end surface of the linkage tooth.

[0016] Furthermore, a sleeve sleeved on the central shaft is provided between the two driven teeth, and a first positioning shaft is symmetrically fixedly connected to the outer side of the sleeve, and the first positioning shaft is connected to the driven teeth.

[0017] Furthermore, a discharge pipe is fixedly connected to the outer side of the bottom of the tank body.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] First, the motor drives the central shaft to rotate. The spiral blades at the bottom of the shaft lift the paint inside the tank as it rotates, creating an upward and downward circulation within the tank. This ensures thorough mixing of the paint and prevents localized accumulation inside the tank. Furthermore, the spiral blade design improves mixing efficiency and ensures uniformity of the paint.

[0020] Secondly, a complex stirring motion is achieved through a direction-changing mechanism mounted on the central shaft, consisting of fixed, driven, and interlocking teeth. The rotation of the fixed teeth drives the driven teeth, which in turn drive the interlocking teeth in the opposite direction, thereby synchronously rotating the stirring assembly connected to their base. This design not only enhances stirring uniformity but also effectively avoids the problem of coating component disruption caused by a single stirring mechanism.

[0021] The stirring assembly design comprises a top plate and a bottom plate mounted on a central axis, connected by a second positioning shaft. These plates, combined with teardrop-shaped stirring blades and a disturbance plate, further enhance the stirring effect. The teardrop-shaped design of the stirring blades reduces resistance during stirring, improving stirring efficiency; the disturbance plate further agitates the paint, ensuring uniform mixing. The coaxial through-hole design of the top and bottom plates allows the central axis to pass through them stably, ensuring the stability of the stirring assembly during rotation.

[0022] Finally, by setting a discharge pipe at the bottom of the tank, it is convenient to discharge the paint after mixing, ensuring the smoothness of the entire production process. This design not only improves the mixing efficiency and effect during use of the device, but also improves the convenience of production operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0036] See Figure 1-4A stirring device for producing water-based paint includes a tank body 1, a motor frame 12 is provided on the top of the tank body 1, a motor 2 is provided on the top of the motor frame 12, the output end of the motor 2 is connected to the central shaft 3, and the bottom outer surface of the central shaft 3 is fixedly connected with a spiral blade 31; the motor 2 is firmly installed on the top of the tank body 1 through the motor frame 12, and drives the central shaft 3 to rotate through the output end; the spiral blade 31 at the bottom of the central shaft 3 lifts the paint inside the tank body 1 when rotating, so that the paint forms a circulation flow in the tank body 1; through the rotation of the central shaft 3, the paint is lifted to a high place and then flows back to the inner wall of the tank body 1, forming a uniform stirring effect.

[0037] A direction-changing mechanism 4 is connected to the central shaft 3. The direction-changing mechanism 4 includes a fixed tooth 41 fixedly connected to the central shaft 3 and a linkage tooth 43 rotatably connected to the central shaft 3. A driven tooth 42 meshes between the fixed tooth 41 and the linkage tooth 43. The rotation of the fixed tooth 41 drives the driven tooth 42 to rotate, and the driven tooth 42 further drives the linkage tooth 43 to rotate in the opposite direction, thereby achieving a complex stirring motion. The rotation of the linkage tooth 43 drives the stirring assembly 5 connected to the bottom thereof to rotate synchronously, thereby fully stirring the paint near the inner wall of the tank body 1.

[0038] The bottom of the linkage tooth 43 is connected to the stirring assembly 5 .

[0039] See Figure 4 The stirring assembly 5 includes a top plate 51 and a bottom plate 53 which are sleeved on the central axis 3, and a second positioning shaft 52 is inserted between the two ends of the top plate 51 and the bottom plate 53, and a stirring blade 54 is sleeved on the second positioning shaft 52; the top plate 51 and the bottom plate 53 are connected together through the second positioning shaft 52 to form a stable supporting structure; the stirring blade 54 is fixed between the top plate 51 and the bottom plate 53 through the second positioning shaft 52. As the stirring assembly 5 rotates, the stirring blade 54 rotates in the tank body 1 to stir the paint.

[0040] See Figure 4 The cross-section of the stirring blade 54 is set to a water drop shape, and the two sides of the stirring blade 54 are fixedly connected with disturbance plates 542 at equal intervals along its height direction; the water drop shape design of the stirring blade 54 is conducive to reducing the resistance during stirring and improving the stirring efficiency; the disturbance plates 542 are arranged at equal intervals on both sides of the stirring blade 54, which can further disturb the paint during the stirring process and improve the uniformity of stirring.

[0041] See Figure 2-4 A third through hole 541 is formed at one end of the stirring blade 54, and the second positioning shaft 52 passes through the third through hole 541; the stirring blade 54 is connected to the second positioning shaft 52 through the third through hole 541, ensuring that the stirring blade 54 remains stable during rotation.

[0042] See Figure 2-4A first through hole 511 is opened through the center of the top of the top plate 51, and a second through hole 531 is opened through the center of the top of the bottom plate 53. The first through hole 511 and the second through hole 531 are coaxially arranged, and the central axis 3 passes through the first through hole 511 and the second through hole 531; through the coaxial through hole arrangement of the top plate 51 and the bottom plate 53, the central axis 3 can stably pass through the top plate 51 and the bottom plate 53, thereby ensuring the stability of the stirring assembly 5 during the rotation process.

[0043] See Figure 3-4 The top of the top plate 51 is symmetrically fixedly connected with a threaded column 512; the upper end surface of the linkage tooth 43 is penetrated by a positioning hole 431 corresponding to the threaded column 512; through the cooperation between the threaded column 512 and the positioning hole 431, the top plate 51 can be firmly installed on the linkage tooth 43, realizing the effective connection between the stirring assembly 5 and the changing mechanism 4.

[0044] See Figure 2-3 A sleeve 44 is provided between the two driven teeth 42 and is sleeved on the central shaft 3. The outer side of the sleeve 44 is symmetrically fixedly connected with a first positioning shaft 441, and the first positioning shaft 441 is connected to the driven teeth 42; the sleeve 44 is connected to the driven teeth 42 through the first positioning shaft 441 to achieve stable transmission of the driven teeth 42; the setting of the first positioning shaft 441 helps to improve the connection strength and stability between the driven teeth 42 and the sleeve 44.

[0045] See Figure 1 The outer side of the bottom of the tank body 1 is fixedly connected with a discharge pipe 11; the discharge pipe 11 is fixedly connected to the outer side of the bottom of the tank body 1, which facilitates the discharge of the paint after the stirring is completed, thereby ensuring the smoothness of the entire production process.

[0046] The working principle of this utility model is:

[0047] When the paint in the tank body 1 is stirred, the motor 2 drives the central shaft 3 connected to its output end to rotate, and the spiral blade 31 provided at the bottom of the central shaft 3 rotates synchronously. When the spiral blade 31 rotates, the paint inside the tank body 1 is lifted, and the lifted paint flows from the center of the tank body 1 to the inner wall of the tank body 1;

[0048] The rotation of the central shaft 3 drives the fixed teeth 41 connected thereto to rotate synchronously. The fixed teeth 41 drive the linkage teeth 43 to rotate in the opposite direction through the driven teeth 42. The rotation of the linkage teeth 43 drives the stirring assembly 5 connected to its bottom to rotate synchronously.

[0049] When the stirring assembly 5 rotates, the stirring blade 54 rotates near the inner wall of the tank body 1 and stirs the paint near the inner wall of the tank body 1;

[0050] Furthermore, with the cooperation of the spiral blade 31 and the stirring blade 54 , the paint in the tank body 1 can be stirred evenly and efficiently.

[0051] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
