Technical Field

[0001] This utility model belongs to the technical field of topcoat processing agitators, specifically relating to an agitator for preparing polyurethane topcoat. Background Technology

[0002] Polyurethane topcoat is a high-performance coating, mainly divided into two-component and one-component types. It has excellent protective and decorative properties. During the preparation of polyurethane topcoat, a stirrer is required for stirring.

[0003] Different raw materials have different specific gravities and will stratify. When the raw materials are stirred, they will move in a circular motion. It is difficult to improve the stratification of raw materials during stirring, which makes it difficult to ensure that the upper and lower layers of raw materials are fully mixed, resulting in low stirring efficiency and poor quality.

[0004] Therefore, a stirrer for preparing polyurethane topcoat is proposed. Summary of the Invention

[0005] This invention provides a stirrer for preparing polyurethane topcoat, the purpose of which is to solve the problems mentioned above.

[0006] This utility model embodiment provides a stirrer for preparing polyurethane topcoat, including a base; a support leg disposed on the top of the base; a stirring tank disposed on the top of the support leg; and an outer material turning assembly disposed inside the stirring tank. The outer material turning assembly includes: a fixing ring disposed at the bottom of the stirring tank; six sets of support units disposed at equal intervals around the top of the fixing ring, each support unit consisting of a support column one and a support column two; a guide platform disposed on the top of each of the six sets of support units; a flow groove opened at the center of one side of the outer wall of the guide platform; an arc surface opened on one side of the outer wall of the guide platform near the outer side of the flow groove; a support plate disposed above the stirring tank; a motor disposed on the top of the support plate; a rotating rod fixed to the output end of the motor; and a stirring head disposed on the outer wall of the rotating rod.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides a stirrer for preparing polyurethane topcoat, including a base 1. Five support legs 2 are evenly spaced around the top of the base 1. A stirring tank 3 is positioned at the top of each support leg 2. A fixing ring 41 from an outer raw material turning assembly 4 is placed at the bottom of the stirring tank 3. Six sets of support units are arranged around the top of the fixing ring 41. Each support unit consists of a first support column 42 and a second support column 43. The first and second support columns 42 and 43 are of different lengths. A guide platform 44 is positioned at the top of the first and second support columns 42 and 43. A flow channel 4 is formed on the outer wall of the guide platform 44 near the inner wall of the stirring tank 3 at its center. 5. Both the guide platform 44 and the flow channel 45 are spiral-shaped. The six guide platforms 44 are staggered in the circumferential direction. Through the spiral guide platforms 44 and the flow channel 45, the polyurethane topcoat raw material in the mixing tank 3 can flow upward along the inner wall of the mixing tank 3 under the action of stirring force. This helps to make the raw material on the lower outer side of the mixing tank 3 flow upward. Through the step-like upward flow, the raw material is turned over from bottom to top, which facilitates the full mixing of the raw material. An arc surface 46 is opened on one side of the outer wall of the guide platform 44 near the outer side of the flow channel 45. The arc surface 46 fits the inner wall of the mixing tank 3 to avoid gaps and ensure the stability of the upward flow of the polyurethane topcoat raw material.

[0026] A support plate 5 is provided above the base 1. An external lifting drive mechanism is provided on one side of the support plate 5. The external lifting drive mechanism is a cylinder. The support plate 5 is driven to rise and fall by the drive end of the cylinder, which can make the stirring head 8 on the support plate 5 rise and fall and move, thereby fully mixing the raw materials at different heights in the mixing tank 3. A motor 6 is provided at the top center of the support plate 5. A rotating rod 7 is fixedly connected to the output end of the motor 6 on one side. A stirring head 8 is provided on the outer wall of the rotating rod 7. A discharge valve 10 is fixedly connected at the bottom center of the mixing tank 3.

[0027] To achieve thorough mixing of the raw materials on the lower outer side of the mixing tank 3, in this embodiment, the control motor 6 pulls the rotating rod 7 to rotate at high speed through its output end on one side. The stirring head 8 on the rotating rod 7 rotates at high speed synchronously. The stirring head 8 disperses and mixes the raw materials in the mixing tank 3. Under the action of the stirring force, the raw materials flow in a circular motion. During the flow, the raw materials flow along the inner wall of the mixing tank 3. Under the action of the flow channel 45, the polyurethane topcoat raw materials flow spirally upward along the flow channel 45. Through the six staggered guide platforms 44, the lower layer of raw materials gradually flows upward. Through the step-like upward flow, the raw materials are turned over from bottom to top, which facilitates thorough mixing of the raw materials and avoids the problem of uneven mixing caused by stratification when different raw materials have different specific gravities.

[0028] Example 2

[0029] Reference Figure 1 , Figure 3 and Figure 4 Based on the above embodiments, this utility model embodiment also proposes a stirrer for preparing polyurethane topcoat, including a rotating rod 7. The bottom end of the rotating rod 7 is provided with an upper disc 91 of the inner raw material turning assembly 9. The bottom of the upper disc 91 is provided with a corrugated pipe 92. The bottom of the corrugated pipe 92 is provided with a lower ring 93. Five guide pillars 94 are circumferentially and evenly spaced near the outer side of the corrugated pipe 92 at the top of the lower ring 93. The top of the guide pillars 94 is provided with a pillar head. By limiting the pillar head, the guide pillars 94 are prevented from falling off the upper disc 91. The guide pillars 94 pass through the upper disc 91. A turning hole 95 is opened at the center of the bottom of the rotating rod 7. A through hole communicating with the turning hole 95 is opened at the center of the bottom of the upper disc 91. By setting the through hole, the raw material in the middle of the lower layer inside the mixing tank 3 can enter the turning hole 95. A discharge port 96 is opened on the outer wall of the rotating rod 7 near the top.

[0030] To achieve thorough mixing of the lower middle material inside the mixing tank 3, in this embodiment, the support plate 5 is driven to rise and fall by the drive end of the external cylinder, and the inner material turning component 9 rises and falls synchronously. When the inner material turning component 9 moves downward, the lower ring 93 first contacts the bottom of the mixing tank 3, and the material in the lower middle of the mixing tank 3 is covered by the corrugated pipe 92. As the inner material turning component 9 continues to move downward, under the pressure of the upper disc 91, the material in the corrugated pipe 92 enters the turning hole 95 under pressure and flows upward along the rotating rod 7, and finally is discharged through the discharge port 96. The material in the lower middle is flowed from bottom to top to the upper center of the mixing tank 3, which facilitates thorough mixing of the material and avoids the problem of uneven mixing caused by stratification when different materials have different specific gravities.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
