Description

Technical Field

[0001] This utility model relates to stirring device technology, and more particularly to a two-component polyurethane stirring rod. Background Technology

[0002] The role of the stirring rod is particularly crucial when processing two-component polyurethane materials. Two-component polyurethane materials typically consist of two components, A and B. These two components maintain independent chemical properties before mixing, but once mixed, a chemical reaction occurs, producing a polyurethane product with specific properties. Therefore, ensuring thorough and uniform mixing of components A and B is a core step in the processing of two-component polyurethane materials.

[0003] Traditional two-component polyurethane stirring rods often suffer from poor mixing uniformity and unsatisfactory mixing effects in practical applications, and may also lead to increased production costs and waste of resources. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to propose a two-component polyurethane stirring rod, which solves the problems of poor stirring uniformity, unsatisfactory stirring effect, and potential increase in production costs and waste of resources associated with traditional two-component polyurethane stirring rods.

[0005] To achieve this objective, the present invention adopts the following technical solution: a two-component polyurethane stirring rod, comprising a stirring rod body, a first spiral protrusion structure, a triangular prism protrusion, and a second spiral protrusion structure, wherein:

[0006] The first spiral protrusion structure, the triangular prism protrusion, and the second spiral protrusion structure are distributed sequentially from top to bottom on the stirring rod body;

[0007] The first spiral protrusion structure forms a threaded feeding area on the body of the stirring rod;

[0008] The triangular prism protrusion forms a rapid stirring zone on the main body of the stirring rod;

[0009] The second spiral protrusion structure forms a rapid discharge zone on the main body of the stirring rod.

[0010] Furthermore, in the rapid stirring zone, the bottom of the triangular prism protrusion is mounted on the stirring rod body, the top of the triangular prism protrusion has an arc-shaped structure, the projected area of ​​the bottom of the triangular prism protrusion on the stirring rod body is S1, and the projected area of ​​the top of the triangular prism protrusion on the stirring rod body is S2. <S2。

[0011] Furthermore, the triangular prism protrusion includes n positive protrusions and n negative protrusions. Along the same axial line, m positive protrusions are evenly distributed at intervals. In another layout along the same axial direction, m negative protrusions are evenly distributed at intervals, where n>m.

[0012] m positive protrusions and m negative protrusions constitute a stirring sub-mechanism, and z stirring sub-mechanisms are evenly distributed on the stirring rod body, z*m=n.

[0013] Furthermore, in the stirring mechanism, m forward protrusions and m reverse protrusions are arranged alternately along the same axial direction.

[0014] Furthermore, in the threaded feeding area, the first spiral protrusion structure is mounted around the stirring rod body, and the cross-sectional dimension of the first spiral protrusion structure gradually decreases from the bottom to the top.

[0015] Furthermore, in the rapid discharge zone, the second spiral protrusion structure is mounted around the main body of the stirring rod, but the second spiral protrusion structure is not continuous, but presents an intermittent spiral shape.

[0016] Furthermore, in the axial direction, the lengths of the threaded feeding zone, the rapid stirring zone, and the rapid discharge zone are all equal to 1 / 3 of the length of the stirring rod body.

[0017] Furthermore, the stirring rod body also includes a horizontal protrusion located at the top of the stirring rod body and disposed on the outer wall of the stirring rod body, with one end of the first spiral protrusion structure fixedly connected to the bottom of the horizontal protrusion.

[0018] Furthermore, the stirring rod body also includes a mounting port, which is connected to the power output end of the drive motor; the connection between the stirring rod body and the drive motor is detachable.

[0019] Furthermore, in the threaded feeding area, the main body of the stirring rod is cylindrical;

[0020] In the rapid mixing zone and the rapid discharge zone, the main body of the mixing rod is conical in shape, and the diameter of the cone in both zones gradually decreases from top to bottom.

[0021] The technical solution provided by this utility model can include the following beneficial effects: When the drive motor starts, the main body of the stirring rod rotates, and the two materials are conveyed forward along the axial direction through the first spiral protrusion structure. The two materials are quickly and thoroughly mixed through the triangular prism protrusion, and the uniformly mixed material is pushed out to the discharge port through the second spiral protrusion structure. Through the unique protrusion structure, the main body of the stirring rod can achieve high-speed and thorough mixing of the two materials, thereby improving the uniformity of stirring and enabling continuous and stable feeding of materials, avoiding material blockage or interruption, and improving production efficiency. This technical solution solves the problems of poor stirring uniformity and unsatisfactory stirring effect of traditional two-component polyurethane stirring rods, which may also lead to increased production costs and waste of resources.

[0031] The following is in conjunction with the appendix Figure 1-4 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0032] In a preferred embodiment of this application, a two-component polyurethane stirring rod includes a stirring rod body 1, a first spiral protrusion structure 21, a triangular prism protrusion 22, and a second spiral protrusion structure 23.

[0033] The first spiral protrusion structure 21, the triangular prism protrusion 22, and the second spiral protrusion structure 23 are distributed from top to bottom on the stirring rod body 1;

[0034] The first spiral protrusion structure 21 forms a threaded feeding area 31 on the stirring rod body 1;

[0035] The triangular prism protrusion 22 forms a rapid stirring zone 32 on the stirring rod body 1;

[0036] The second spiral protrusion structure 23 forms a rapid discharge zone 33 on the stirring rod body 1.

[0037] Specifically, the stirring rod body 1 is installed inside the rotating drum and rotates through the power output of the drive motor. The stirring rod body 1 includes a first spiral protrusion structure 21, a triangular prism protrusion 22, and a second spiral protrusion structure 23. These three protrusion structures are distributed sequentially from top to bottom. The first spiral protrusion structure 21 forms a threaded feeding area 31 on the stirring rod body 1; the triangular prism protrusion 22 forms a rapid stirring area 32 on the stirring rod body 1; and the second spiral protrusion structure 23 forms a rapid discharge area 33 on the stirring rod body 1. When the drive motor is started, the stirring rod body 1 rotates, and through the first spiral protrusion structure 21... The spiral protrusion structure 21 conveys the two materials forward along the axial direction, and the triangular prism protrusion 22 mixes the two materials quickly and thoroughly. The second spiral protrusion structure 23 pushes the uniformly mixed material out of the discharge port. Through the unique protrusion structure, the stirring rod body 1 can achieve high-speed and thorough mixing of the two materials, thereby improving the uniformity of mixing and enabling continuous and stable feeding of materials, avoiding material blockage or interruption, and improving production efficiency. This technical solution solves the problems of poor mixing uniformity and unsatisfactory mixing effect of traditional two-component polyurethane stirring rods, which may also lead to increased production costs and waste of resources.

[0038] In an optional embodiment, in the rapid stirring zone 32, the bottom of the triangular prism protrusion 22 is mounted on the stirring rod body 1, the top of the triangular prism protrusion 22 has an arc-shaped structure, the projected area of ​​the bottom of the triangular prism protrusion 22 on the stirring rod body 1 is S1, and the projected area of ​​the top of the triangular prism protrusion 22 on the stirring rod body 1 is S2. <S2。

[0039] Specifically, the projected area of ​​the triangular prism protrusion 22 gradually increases from the bottom S1 to the top S2. This design helps the stirring rod body 1 to form a more uniform fluid dynamic field during stirring, reducing dead zones and allowing materials to flow and mix more fully. Furthermore, since the top of the triangular prism protrusion 22 is an arc-shaped structure, the arc-shaped structure not only helps the stirring rod body 1 generate stronger shear and impact forces during stirring, thereby more effectively mixing and dispersing materials and improving stirring efficiency, but also helps reduce material residue on the stirring rod body 1, making cleaning and maintenance more convenient and quick.

[0040] In an optional embodiment, the triangular prism protrusion 22 includes n forward protrusions 221 and n reverse protrusions 222. Along the same axial line, m forward protrusions 221 are evenly distributed at intervals. In another arrangement along the same axial direction, m reverse protrusions 222 are evenly distributed at intervals, where n>m.

[0041] m positive protrusions 221 and m negative protrusions 222 constitute a stirring sub-mechanism, and z stirring sub-mechanisms are evenly distributed on the stirring rod body 1, z*m=n.

[0042] Specifically, each of the stirring sub-mechanisms has an equal number of forward protrusions 221 and reverse protrusions 222, both being m. There are z stirring sub-mechanisms distributed on the stirring rod body 1, and z*m=n. This means that the number of forward protrusions 221 and reverse protrusions 222 on the stirring rod body 1 is balanced. This design can expand the stirring range while ensuring the stirring force, ensuring that the material can be fully stirred in every corner of the rotating drum.

[0043] In an alternative embodiment, in the stirring mechanism, m forward protrusions 221 and m reverse protrusions 222 are arranged alternately along the same axial direction.

[0044] Specifically, in the same axial direction, one of the positive protrusions 221 is followed by one of the negative protrusions 222, and one of the negative protrusions 222 is followed by one of the positive protrusions 221. This design more effectively pushes and mixes materials. The alternating arrangement of the positive protrusions 221 and the negative protrusions 222 allows the stirring rod body 1 to generate more complex hydrodynamic effects during stirring, which helps to break the adhesion between materials and improve stirring efficiency and mixing uniformity. When the stirring rod body 1 rotates, it can also generate a more balanced stirring force, thereby reducing energy consumption and wear caused by local over-stirring.

[0045] In an alternative embodiment, in the threaded feeding area 31, the first spiral protrusion structure 21 is mounted around the stirring rod body 1, and the cross-sectional dimensions of the first spiral protrusion structure 21 gradually decrease from the bottom to the top.

[0046] Specifically, the spiral shape and gradually decreasing cross-sectional size of the first spiral protrusion structure 21 not only help the material to be conveyed upward along the spiral trajectory when the stirring rod body 1 rotates, but also make the material more effectively pushed, reducing the resistance and friction of the material during the feeding process, thereby improving the feeding efficiency. This structure also helps to reduce the risk of material accumulation and blockage at the top, ensuring that the material remains continuous and stable during the feeding process, and avoiding material blockage or interruption.

[0047] In an optional embodiment, in the rapid discharge zone 33, the second spiral protrusion structure 23 is mounted around the stirring rod body 1, but the second spiral protrusion structure 23 is not continuous, but presents an intermittent spiral shape.

[0048] Specifically, the discontinuous spiral shape allows the second spiral protrusion 23 to create intermittent squeezing and pushing effects on the material when the stirring rod body 1 rotates. This intermittent squeezing helps the material pass through the discharge port more quickly, thereby improving discharge efficiency. At the same time, the material does not form a continuous channel between the second spiral protrusions 23, thereby reducing material residue on the stirring rod body 1. This helps to keep the stirring equipment clean and reduce equipment failures caused by material residue.

[0049] In an optional embodiment, the lengths of the threaded feeding zone 31, the rapid stirring zone 32, and the rapid discharge zone 33 in the axial direction are all equal to 1 / 3 of the length of the stirring rod body 1.

[0050] Specifically, the mixing rod body 1 is divided into three equal-length regions, each capable of fulfilling its specific function. The threaded feeding zone 31 continuously and stably feeds materials into the mixing zone, the rapid mixing zone 32 utilizes a specially designed protruding structure to mix materials quickly and thoroughly, and the rapid discharge zone 33 ensures that materials can be discharged from the mixing equipment quickly and smoothly. This functional allocation makes the mixing process more efficient and orderly; and because each functional zone is of equal length and easily identifiable, it simplifies equipment maintenance. For example, when cleaning the mixing equipment, each functional zone can be cleaned specifically to ensure the cleanliness and hygiene of the equipment.

[0051] In an optional embodiment, the stirring rod body 1 further includes a horizontal protrusion 11, which is located at the top of the stirring rod body 1 and is disposed on the outer wall of the stirring rod body 1. One end of the first spiral protrusion structure 21 is fixedly connected to the bottom of the horizontal protrusion 11.

[0052] Specifically, the horizontal protrusion 11 serves as an extension of the stirring rod body 1, increasing the overall structural strength of the stirring rod body 1. In particular, during the stirring process, when the stirring rod body 1 is subjected to a large force or torque, the horizontal protrusion 11 provides additional support, preventing the stirring rod body 1 from deforming or being damaged. Furthermore, the horizontal protrusion 11 can drive the first spiral protrusion structure 21 to rotate together, thereby generating a stronger stirring and shearing effect on the material. This design helps to improve stirring efficiency, allowing the material to be mixed and dispersed more thoroughly.

[0053] In an optional embodiment, the stirring rod body 1 further includes a mounting port 12, which is connected to the power output end of the drive motor; the connection between the stirring rod body 1 and the drive motor is detachable.

[0054] Specifically, the detachable installation method allows the stirring rod body 1 to be easily installed and quickly disassembled when needed, simplifying the assembly and disassembly process of the stirring equipment, improving work efficiency, and since the stirring rod body 1 is detachable, it can be removed separately when cleaning, maintenance or replacement of the stirring rod is required, without the need for complex disassembly of the entire stirring equipment. This reduces maintenance costs and extends the service life of the equipment.

[0055] In an alternative embodiment, in the threaded feeding zone 31, the stirring rod body 1 is cylindrical in shape;

[0056] In the rapid mixing zone 32 and the rapid discharge zone 33, the shape of the mixing rod body 1 is a cone, and the diameter of the cone in these two zones gradually decreases from top to bottom.

[0057] Specifically, the cylindrical shape provides stable material conveying in the threaded feeding zone 31. Due to the uniform cross-section of the cylinder, the material can move smoothly downwards along the mixing rod body 1 under the push of the first spiral protrusion structure 21, reducing material blockage during conveying. The conical shape provides better mixing effect in the rapid mixing zone 32 and the rapid discharge zone 33. As the diameter of the cone gradually decreases from top to bottom, the material is subjected to stronger shear and extrusion forces during mixing, thereby improving the uniformity and efficiency of mixing. At the same time, the cone design can better adapt to the flow characteristics of the material. In the rapid mixing zone 32, the material is subjected to strong mixing action, and the cone shape helps the material to disperse around the mixing rod body 1, increasing the contact area for mixing. In the rapid discharge zone 33, the cone shape helps the material pass through the mixing rod body 1 better, reducing resistance during discharge.

[0058] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
