Description

Technical Field

[0001] This utility model relates to the field of modifier mixing technology, and in particular to an automatic mixing device for modifiers. Background Technology

[0002] Modifiers are functional additives added during material processing or synthesis to improve certain physical, chemical, or mechanical properties of materials. Their mechanism of action typically involves physical interactions or chemical reactions with the molecular structure or morphology of the material, thereby altering its properties. For example, in metal smelting, modifiers can improve the strength and toughness of metals by refining grains and purifying the microstructure; in plastics or rubber products, modifiers can improve their weather resistance, wear resistance, or processing performance. Modifiers are widely used in metallurgy, chemical industry, building materials, polymer materials, and other fields, and are important auxiliary materials for improving material performance and extending service life.

[0003] In industries such as metallurgy, building materials, and chemicals, modifiers are crucial additives for improving the performance of base materials. The precision of their formulation and the uniformity of their mixing directly affect the performance and stability of the final product. Currently, existing modifier mixing devices generally suffer from several shortcomings: Firstly, the lack of pretreatment of the modifier raw materials prevents effective crushing and sieving of agglomerated materials added to the mixing tank, resulting in uneven particle size distribution of the modifier and hindering thorough mixing. Secondly, existing devices often employ a single agitator design, limiting the mixing range to the center of the tank and failing to effectively reach materials accumulated around the perimeter, leading to mixing dead zones and localized accumulation. Therefore, current technologies still suffer from limited mixing effects and poor homogeneity in practical applications, making it difficult to meet the process requirements for formulating high-performance modifiers.

[0004] Based on this, we propose an automatic mixing device for modifiers to solve the problems mentioned above. Utility Model Content

[0009] Optionally, a stirring motor is installed on the top of the mixing tank, and a feed inlet is provided on the top side of the mixing tank near the stirring motor. The feed inlet is matched with the structure of the discharge hopper, and the feed inlet and the discharge hopper are connected by a plug-in fit. A stirring cavity is provided inside the mixing tank, and a spiral stirrer is connected inside the stirring cavity through a bearing.

[0024] 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.

[0025] Example: Refer to Figures 1 to 5This utility model provides an embodiment of an automatic mixing device for a modifier, comprising a mixing tank 1, a drive base 2 installed at the bottom of the mixing tank 1, and a feeding assembly 3 at the top of the mixing tank 1. The feeding assembly 3 includes a material screening box 4, a feeding hopper 5 at the top of the material screening box 4, two sets of crushing shafts 6 connected to the inside of the feeding hopper 5 via bearings, a transmission component 7 on one side of the feeding hopper 5, the transmission component 7 being connected to the two sets of crushing shafts 6 via transmission, a feeding trough 8 at the top of the material screening box 4, a discharge plate 9 inclinedly arranged on one side of the material screening box 4, a discharge port 10 extending through the side of the material screening box 4 near the discharge plate 9, a screening screen 11 inclinedly arranged inside the feeding trough 8, the installation angle of the screening screen 11 matching the structure of the discharge plate 9, and a motor drive box 12 arranged on the outside of the material screening box 4, the motor drive box 12 being connected to the transmission component 7 via a transmission belt. The bottom of the mixing tank 4 is also equipped with a discharge hopper 13. The modifier mixing device works in conjunction with the crushing shaft 6, the transmission component 7 and the motor drive box 12. When the motor drive box 12 is powered on and drives the two sets of crushing shafts 6 to rotate inside the feed hopper 5, the agglomerated modifier put into the feed hopper 5 can be crushed. The crushed modifier can fall into the material screening box 4. The material screening box 4 works in conjunction with the discharge plate 9, the discharge port 10, the screening screen plate 11 and the discharge hopper 13 to screen the modifier falling into the material screening box 4. When the particle size of the modifier meets the mixing requirements, it can pass through the screening screen plate 11 and be discharged into the mixing tank 1 through the discharge hopper 13 and the feed port 15. When the particle size of the modifier does not meet the mixing requirements, it can be filtered out by the screening screen plate 11 and discharged outward along the inclined installation angle of the screening screen plate 11 and the discharge plate 9.

[0026] A stirring motor 14 is installed on the top of the mixing tank 1. An inlet 15 is located on the top side of the mixing tank 1 near the stirring motor 14. The inlet 15 is structurally matched with the discharge hopper 13, and the inlet 15 and discharge hopper 13 are connected by a plug-in joint. A stirring cavity 16 is provided inside the mixing tank 1. A spiral stirrer 17 is connected to the inside of the stirring cavity 16 via bearings. The spiral stirrer 17 is connected to the output end of the stirring motor 14 via a transmission connection. Positioning plates 18 are also provided at the four corners of the bottom of the mixing tank 1. The spiral stirrer 17 installed inside the mixing tank 1 is connected to the output end of the stirring motor 14 via a transmission connection. When the stirring motor 14 is powered on, the spiral stirrer 17 can stir the contents of the mixing tank 1. The modifier is mixed and stirred. A circular groove 19 is provided at the bottom of the mixing tank 1. A first transmission base plate 20 is connected to the inside of the circular groove 19 through a bearing. A second transmission base plate 21 is installed at one end of the first transmission base plate 20. The second transmission base plate 21 is located at the bottom of the inner cavity of the mixing tank 1. The second transmission base plate 21 is connected to the spiral stirrer 17 through a bearing. Stirring blades 22 are installed on both sides of the top of the second transmission base plate 21. By adding stirring blades 22 on both sides of the top of the second transmission base plate 21, the raw materials accumulated at the bottom and side wall areas of the mixing tank 1 can be fully stirred and flowed, avoiding local accumulation and mixing dead corners. This ensures that the modifier is evenly distributed in the entire mixing tank 1, achieving the purpose of high mixing uniformity and stable mixing effect.

[0027] Both sets of stirring blades 22 are equipped with guide sliders 23 at their tops. An annular guide groove 24 is provided at the top of the inner cavity of the mixing tank 1. The annular guide groove 24 matches the structure of the guide slider 23, and the annular guide groove 24 and guide slider 23 are in sliding fit. Through the sliding fit structure between the annular guide groove 24 and guide slider 23, the tops of the stirring blades 22 rotating on both sides of the inner cavity of the mixing tank 1 can be guided and limited. This effectively prevents the stirring blades 22 from shaking or deviating during high-speed rotation, thus ensuring that the stirring blades 22 work stably along a predetermined trajectory. This ensures that the modifier raw materials inside the mixing tank 1 can be evenly agitated and stirred. The output end of the drive base 2 is connected to a third transmission base plate 25, which matches the structure of the circular groove 19. The third transmission base plate 25 is fixedly connected to the first transmission base plate 20. The top four corners of the drive base 2 are also provided with positioning slots 26. Through the fixed connection structure between the third transmission base 25 and the first transmission base 20, when the drive base 2 is powered on, the rotational power can be transmitted from the third transmission base 25 to the second transmission base 21 and the stirring blades 22. This can drive the stirring blades 22 on both sides of the inner cavity of the mixing tank 1 to rotate stably, which can fully stir the modifier raw materials gathered on the edge and corner of the tank. The positioning slots 26 and the positioning plates 18 are matched in structure. The positioning slots 26 and the positioning plates 18 are engaged. Through the engagement structure between the positioning slots 26 and the positioning plates 18, the mixing tank 1 and the drive base 2 can be quickly and accurately positioned and stably connected. This can ensure that the mixing tank 1 remains stable during the operation of the spiral agitator 17 and the stirring blades 22.

[0028] Working Principle: The modifier mixing device designed in this scheme mainly consists of a mixing tank 1, a drive base 2, and a feeding assembly 3. The feeding assembly 3 includes a material screening box 4 and a feeding hopper 5. The raw material modifier first enters the device through the feeding hopper 5. Two sets of crushing shafts 6 are installed inside the feeding hopper 5, which are driven by the transmission component 7 and the motor drive box 12. When the motor drive box 12 is powered on, the crushing shafts 6 rotate at high speed inside the feeding hopper 5, which can crush the lumpy modifier. This crushing process effectively prevents lumpy materials from entering the mixing tank 1 and causing uneven mixing, and also ensures that the particle size distribution of the modifier is uniform during subsequent mixing, thereby improving the stability of the mixing effect. Consistency is ensured by the pulverized modifier falling into the material screening box 4. Through the coordinated action of the discharge plate 9, discharge port 10, screening screen 11, and discharge hopper 13, the material screening box 4 can achieve particle screening and flow direction control. When the particle size of the modifier meets the mixing requirements, it can smoothly pass through the screening screen 11 into the discharge hopper 13 and be discharged into the mixing tank 1 through the feed port 15. When the particle size does not meet the requirements, large particles or unpulverized materials will be blocked by the screening screen 11 and discharged along the inclined angle between the screening screen 11 and the discharge plate 9, realizing automatic rejection and recycling. This screening process ensures that the raw materials entering the mixing tank 1 are all particles that meet the mixing requirements, effectively improving the mixing uniformity and avoiding the generation of local insufficient mixing or mixing dead zones, while reducing manual intervention and rework.

[0029] The modifier mixing device designed in this scheme allows the modifier raw material entering the mixing tank 1 to be initially stirred by a spiral stirrer 17 driven by a stirring motor 14. The spiral stirrer 17 is connected to the output end of the stirring motor 14. When the stirring motor 14 is powered on, the spiral stirrer 17 rotates inside the mixing tank 1, causing the added modifier raw material to be agitated and uniformly stirred. This initial stirring breaks up the layered distribution formed during the material feeding process, allowing the material to flow fully inside the mixing tank 1, significantly improving the mixing uniformity. To further eliminate mixing dead zones, a circular groove 19 and a first transmission base plate 20 are provided at the bottom of the mixing tank 1. The second transmission base plate 21 and stirring blade 22, along with the guide slider 23 and annular guide groove 24, ensure that the stirring blade 22 maintains stable operation during rotation, avoiding mixing dead zones caused by swaying. The third transmission base plate 25 is fixedly connected to the first transmission base plate 20. When the drive base 2 is powered on, it can drive the two sets of stirring blades 22 to rotate on both sides of the inner cavity of the mixing tank 1, which can stir the modifier raw materials that accumulate at the edge and corner of the tank. This multi-layer stirring structure can effectively prevent local accumulation or mixing dead zones, ensuring that the modifier is evenly distributed throughout the tank, thereby significantly improving the mixing effect and material homogeneity.
