Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical mixing equipment technology, specifically to an epoxy resin mechanical mixing equipment with an anti-overflow structure. Background Technology
[0002] Epoxy resin, as a high-performance polymer material, is widely used in adhesives, composite materials, coatings, and many other fields. Its molding quality is closely related to the uniformity and stability of the mixing process. In the production and processing of epoxy resin, mechanical mixing equipment is the core equipment for achieving uniform mixing of resin with curing agents, fillers, and other components; its performance directly affects the final performance of the product.
[0003] Material spills not only waste raw materials and increase production costs, but also adhere to equipment surfaces, floors and surrounding facilities, making subsequent cleanup tedious, consuming a lot of manpower and resources, and potentially causing safety hazards such as equipment corrosion and short circuits.
[0004] To mitigate overflow issues, some existing equipment has attempted to use manual monitoring of the feed rate or simple liquid level alarm devices, but the results have been unsatisfactory. Manual monitoring relies on the operator's experience and judgment, resulting in delayed response and low accuracy, making it difficult to adapt to the needs of continuous production. Simple liquid level alarm devices can only issue warnings when the liquid level is too high and cannot actively intervene in the feeding process, thus failing to fundamentally prevent material overflow. Furthermore, the feeding structure of existing equipment is mostly fixedly connected to the mixing tank, and the feeding position is fixed. When the liquid level in the mixing tank changes, the relative position of the feed inlet and the liquid surface cannot be adjusted, further exacerbating the risk of overflow. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides an epoxy resin mechanical mixing device with an anti-overflow structure, which can effectively solve the problems in the prior art.
[0006] This utility model provides an epoxy resin mechanical mixing device with an anti-overflow structure, including a mixing tank. A cover plate is fixed to the top of the mixing tank, and a power end is provided in the middle of the top of the cover plate. A feeding structure is provided on one side of the cover plate. The feeding structure includes a movable plate disposed inside the mixing tank and an anti-overflow component fixed to one side of the movable plate. The anti-overflow component includes a lower funnel fixed to the movable plate, a blocking ring disposed inside the lower funnel, and a float rod fixed to the bottom of the blocking ring. Multiple sets of side float rods are fixed to the bottom end of the movable plate, and multiple sets of overflow holes are opened on the side wall of the lower funnel.
[0007] Furthermore, an inner groove is provided on the side wall of the mixing tank, and a protrusion is integrally fixed on the outer side of the moving plate, which is disposed in the inner groove.
[0008] Furthermore, a feed pipe is fixed to the top of the cover plate, the feed pipe is located at the top of the lower funnel, the outer side of the lower funnel is a flange structure, and a round hole is also opened in the middle of the moving plate. The lower funnel and the moving plate are fixedly connected by a bottom nut.
[0009] Furthermore, the power end includes a drive motor fixed to the top of the cover plate, a drive shaft connected to the output of the drive motor, and a stirring blade fixed to the outside of the drive shaft. The depth of the inner tank inside the mixing tank is less than the depth of the stirring blade.
[0010] Furthermore, the lower funnel is a hollow funnel shape that is wider at the top and narrower at the bottom. A circular hole is provided at the bottom of the lower funnel, and the float rod is placed inside the circular hole. A locking bolt is fitted on the outer side of the top of the lower funnel.
[0011] Furthermore, the plugging ring has an inverted bowl-shaped structure, and its outer area is larger than the area of the overflow hole on the lower funnel.
[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: The feeding structure of the equipment innovatively incorporates an anti-overflow component consisting of a lower funnel, a blocking ring, and a float rod, which, together with the overflow hole on the side wall of the lower funnel, forms an active anti-overflow mechanism. When material accumulates in the lower funnel, causing the liquid level to rise, the float rod moves upward under buoyancy, causing the inverted bowl-shaped blocking ring to rise synchronously until it covers the overflow hole, blocking further material from entering the lower funnel. When the liquid level drops, the float rod causes the blocking ring to fall back, the overflow hole reopens, and feeding resumes, achieving automatic start / stop and anti-overflow control of the feeding process. Simultaneously, multiple sets of side float rods at the bottom of the moving plate can rise and fall synchronously with the overall liquid level in the mixing tank, adjusting the height of the moving plate and the anti-overflow component as a whole, further improving the anti-overflow adaptability. This structure fundamentally avoids material overflow, reduces raw material waste, lowers equipment cleaning costs, and reduces safety risks caused by overflow.
[0013] In this device, the matching relationship between the depth of the inner tank and the depth of the stirring blades is optimized, ensuring that the depth of the inner tank is less than the depth of the stirring blades. This guarantees that the stirring blades can cover the entire mixing tank, including the inner tank area, when rotating, avoiding the problem of insufficient material mixing in the inner tank area of traditional equipment. Simultaneously, the drive motor drives the drive shaft and stirring blades to rotate stably, forming a highly efficient mixing flow field. This ensures that the epoxy resin and each component material are in full contact and uniformly mixed, significantly improving the stability and consistency of product quality.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments 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. Obviously, 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 embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0022] The present invention will be further described below with reference to the embodiments.
[0023] Example: Epoxy resin mechanical mixing equipment with an anti-overflow structure, see attached document. Figure 1 - Appendix Figure 5The system includes a mixing tank 1, a cover plate 13 fixed to the top of the mixing tank 1, a power end 2 provided in the middle of the top of the cover plate 13, a feeding structure 3 provided on one side of the cover plate 13, the feeding structure 3 including a movable plate 31 provided in the mixing tank 1 and an anti-overflow component 33 fixed to one side of the movable plate 31, the anti-overflow component 33 including a lower funnel 331 fixed on the movable plate 31, a blocking ring 332 provided in the lower funnel 331 and a float rod 333 fixed to the bottom of the blocking ring 332, a number of side float rods 34 fixed to the bottom of the movable plate 31, and a number of overflow holes 334 opened on the side wall of the lower funnel 331;
[0024] An inner groove 11 is formed on the side wall of the mixing tank 1, and a protrusion 32 is integrally fixed on the outer side of the moving plate 31. The protrusion 32 is set in the inner groove 11. The equipment optimizes the matching relationship between the depth of the inner groove 11 and the depth of the stirring blade 23 in the mixing tank 1, so that the depth of the inner groove 11 in the mixing tank 1 is less than the depth of the stirring blade 23. This ensures that the stirring blade 23 can cover the entire area of the mixing tank 1, including the inner groove 11 area, when rotating, avoiding the problem of insufficient material mixing in the inner groove 11 area of traditional equipment. At the same time, the drive motor 21 drives the drive shaft 22 and the stirring blade 23 to rotate stably, forming a highly efficient stirring flow field, ensuring that the epoxy resin and each component material are in full contact and uniformly mixed, significantly improving the stability and consistency of product quality.
[0025] A feed pipe 12 is fixed to the top of the cover plate 13. The feed pipe 12 is located at the top of the lower funnel 331. The outer side of the lower funnel 331 has a flange structure, and a round hole is also opened in the middle of the moving plate 31. The lower funnel 331 and the moving plate 31 are fixedly connected by a bottom nut 335. The protrusion 32 fixedly on the outer side of the moving plate 31 forms a sliding fit structure with the inner groove 11 of the side wall of the mixing tank 1. This provides a stable guide for the lifting and lowering of the moving plate 31 and avoids the material entering the gap from affecting the movement accuracy, thus improving the stability of the overall structure. The lower funnel 331 adopts a hollow funnel-shaped structure that is larger at the top and smaller at the bottom, which facilitates the rapid introduction of materials. Its outer flange structure is fixedly connected to the moving plate 31 by a bottom nut 335. The connection is firm and easy to disassemble, which facilitates later maintenance and cleaning. The locking bolt 336 on the outer side of the top of the float rod 333 can be adjusted according to actual production needs to adjust the installation height of the float rod 333, thereby setting different anti-overflow trigger liquid levels to adapt to the mixing needs of epoxy resin materials of different viscosities and batches, thus improving the versatility of the equipment.
[0026] The power end 2 includes a drive motor 21 fixed to the top of the cover plate 13, a drive shaft 22 connected to the output of the drive motor 21, and a stirring blade 23 fixed to the outside of the drive shaft 22. The depth of the inner trough 11 in the mixing tank 1 is less than the depth of the stirring blade 23. The feed pipe 12 at the top of the cover plate 13 is precisely connected to the top of the lower funnel 331 to form a stable feeding channel, ensuring efficient material introduction. The automatic start-stop function of the anti-overflow component 33 replaces the traditional manual monitoring feeding method, reducing human intervention and the labor intensity of operators. At the same time, it avoids the lag and error rate of manual operation, making the feeding process and the mixing process work together, improving the overall production efficiency and adapting to the needs of continuous industrial production.
[0027] The lower funnel 331 is a hollow funnel shape that is larger at the top and smaller at the bottom. A round hole is opened at the bottom of the lower funnel 331, and the float rod 333 is placed in the round hole. The float rod 333 is placed on the outer side of the top of the lower funnel 331 and a locking bolt 336 is fitted on it. The plug ring 332 has an inverted bowl-shaped structure, and the outer area is larger than the area of the overflow hole 334 on the lower funnel 331. The feeding structure 3 of the equipment innovatively sets up an anti-overflow component 33 composed of the lower funnel 331, the plug ring 332, and the float rod 333, which, together with the overflow hole 334 on the side wall of the lower funnel 331, forms an active anti-overflow mechanism. When the liquid level rises due to material accumulation in the lower funnel 331, the float rod 333 moves upward under buoyancy, causing the inverted bowl-shaped blocking ring 332 to rise synchronously until the blocking ring 332 covers the overflow hole 334, blocking the material from continuing to enter the lower funnel 331. When the liquid level drops, the float rod 333 causes the blocking ring 332 to fall back, and the overflow hole 334 reopens to resume feeding, realizing automatic start / stop and overflow prevention control of the feeding process. At the same time, the multiple sets of side float rods 34 at the bottom of the moving plate 31 can rise and fall synchronously with the overall liquid level in the mixing tank 1, driving the moving plate 31 and the overflow prevention component 33 to adjust their overall height, further improving the overflow prevention adaptability. This structure fundamentally avoids material overflow, reduces raw material waste, lowers equipment cleaning costs, and reduces the safety risks caused by overflow.
[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
