Description

Technical Field

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

[0002] In industrial production, material mixing is an indispensable part of many processes and is widely used in industries such as chemicals, food, pharmaceuticals, and building materials. As a key piece of equipment for achieving uniform material mixing, the mixer's efficiency and mixing quality directly affect the stability of subsequent production processes and the quality of the final product. Therefore, optimizing the performance of mixers has always been a key research focus in the industry.

[0003] Currently, most mixers on the market use manual feeding or simple mechanical conveying for material loading. Manual feeding is not only labor-intensive but also difficult to precisely control the amount of material fed each time, easily leading to imbalances in the material ratio due to human error and affecting the mixing effect. While simple mechanical conveying reduces manual intervention, it often lacks a quantitative control mechanism, easily resulting in over- or under-feeding of material, causing material waste or insufficient mixing. Furthermore, during the material mixing process, traditional mixers often use unidirectional rotating blades. Under centrifugal force, material tends to gather towards the edge of the shell, resulting in differences in the degree of mixing between the center and the edge. This makes it difficult to achieve uniform mixing of all materials, especially for highly viscous or unevenly sized materials, thus limiting the mixing efficiency and quality improvement of mixers.

[0004] In response to this technical problem, this application proposes an automatic feeding device for a mixer. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding device for a mixer. Through the cooperation of a reciprocating container and a flip-top, it achieves automatic quantitative feeding of materials, improving automation and accuracy, and reducing waste and manual operation. The reverse-rotating stirring blades and stirring ring solve the problem of material accumulation and improve the uniformity of mixing.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic feeding device for a mixer includes a top cover and a housing. The outer wall of the top cover is fixedly connected to the upper side of the housing. A bottom shell is fixedly connected to the lower side of the housing. A support leg is fixedly connected to the lower outer wall of the bottom shell. A stirring assembly is provided on the lower side of the top cover. A motor is provided on the upper side of the top cover. A rotating shaft is fixedly connected to the rotating end of the motor.

A support frame is fixedly connected to the upper side of the feeding port. A feeding assembly is provided on the outer wall of the support frame.

[0008] Furthermore, the stirring assembly includes a stirring blade fixedly connected to the lower outer wall of the rotating shaft, a toothed ring rotatably connected to the lower outer wall of the top cover, a connecting rod fixedly connected to the lower side of the toothed ring, and a stirring ring fixedly connected to the lower side of the connecting rod.

[0009] Furthermore, the feeding assembly includes a container slidably connected inside the support frame, and a container is fixedly connected to the upper side of the support frame.

[0010] Furthermore, the feeding assembly includes a container slidably connected inside the support frame, a container fixedly connected to the upper side of the support frame, and a reciprocating lead screw provided on the left outer wall of the container.

[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] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an automatic feeding device for a mixer, comprising a top cover 7 and a housing 6. The outer wall of the top cover 7 is fixedly connected to the upper side of the housing 6. A bottom shell 13 is fixedly connected to the lower side of the housing 6. A support leg 10 is fixedly connected to the lower outer wall of the bottom shell 13. A stirring blade 12 is provided on the lower side of the top cover 7. A gear ring 16 is rotatably connected to the lower outer wall of the top cover 7. A connecting rod 9 is fixedly connected to the lower side of the gear ring 16. A stirring ring 8 is fixedly connected to the lower side of the connecting rod 9. A motor 1 is provided on the upper side of the top cover 7. A rotating shaft 11 is fixedly connected to the rotating end of the motor 1. A sprocket 17 is fixedly connected to the rotating end of the motor 1. A feeding port is opened on the right side of the outer wall of the top cover 7. A support frame 4 is fixedly connected to the upper side of the feeding port. A container 21 is provided on the outer wall of the support frame 4. A container 3 is fixedly connected to the upper side of the support frame 4.

[0026] Specifically, the device is mainly used for mixing materials, so it is often necessary to control the amount of material entering during use to improve the mixing effect. Therefore, an automatic quantitative feeding device was designed. Starting the motor 1 will drive the rotating shaft 11 and stirring blade 12 on the lower side to stir. In addition, the motor 1 will drive the sprocket 17 and chain 2 to rotate, thereby driving the sprocket 5 to rotate. The sprocket 5 will drive the bevel gear 20 and bevel gear 18 to rotate, which will drive the reciprocating screw 22 to rotate. Due to the nature of the reciprocating screw 22, the container 21 will move back and forth on the reciprocating screw 22. When the reciprocating screw 22 moves to the left, the flip cover 19 will rotate downward under the lower baffle of the support frame 4 due to gravity, causing the material inside to fall out. The container 21 has a certain length on the right side, and when it moves to the left, it will block the lower side of the container 3 to prevent the material from falling out and entering the feeding port. When the container 21 slides to the right, it will fill the lower side of the container 3 with material. Traditional devices tend to push materials to the outer wall 6 during mixing, making it difficult for them to mix with the materials in the middle. Therefore, a side-mixing structure was designed. When the rotating shaft 11 rotates, it drives the large gear 14 to rotate, which in turn drives the small gear 15 and the gear ring 16 to rotate. A connecting rod 9 is fixed to the lower side of the gear ring 16, which drives the mixing ring 8 to rotate. Because of the additional small gear 15, the mixing blade 12 and the mixing ring 8 can rotate in opposite directions, thus ensuring that the internal materials are fully mixed. A baffle is fixed to the lower side of the top cover 7, and the feed port passes through the top cover 7 and the baffle to prevent the transmission between the gears from jamming. The side rotation of the gear ring 16 is on the outer edge of the baffle, which does not affect the transmission between the internal gears, nor does it affect the connection of the connecting rod 9 on the lower side.

[0027] Reference Figures 2-4 A large gear 14 is fixedly connected to the upper outer wall of the rotating shaft 11, and the outer wall of the large gear 14 is rotatably connected to the lower outer wall of the top cover 7. A small gear 15 is rotatably connected to the bottom end of the top cover 7, and the outer wall of the small gear 15 meshes with the outer wall of the large gear 14. The outer wall of the small gear 15 meshes with the inner wall of the gear ring 16. A baffle is fixedly connected to the lower side of the support frame 4, and a flip cover 19 is rotatably connected to the lower side of the container 21. The outer wall of the flip cover 19 is set on the upper side of the baffle. A chain 2 is meshed with the outer wall of the second sprocket 17, and a first sprocket 5 is meshed with the inner wall of the other side of the chain 2. The outer wall of the first sprocket 5 is rotatably connected to the upper side of the top cover 7, and a second bevel gear 20 is fixedly connected to the upper side of the first sprocket 5. The upper outer wall of bevel gear 20 is meshed with bevel gear 18. The right side of bevel gear 18 is fixedly connected to reciprocating screw 22. The outer wall of reciprocating screw 22 is rotatably connected to the inside of support frame 4. The left outer wall of container 21 is sleeved on reciprocating screw 22.

[0028] Specifically, a large gear 14 is fixedly connected to the upper outer wall of the rotating shaft 11, and the outer wall of the large gear 14 is rotatably connected to the lower outer wall of the top cover 7. A small gear 15 is rotatably connected to the bottom end of the top cover 7, and the outer wall of the small gear 15 meshes with the outer wall of the large gear 14. At the same time, the outer wall of the large gear 14 meshes with the inner wall of the gear ring 16, forming a reverse transmission structure. A baffle is fixedly connected to the lower side of the support frame 4, and a flip cover 19 is rotatably connected to the lower side of the container 21. The outer wall of the flip cover 19 is set on the upper side of the baffle, and the flip cover 19 is realized through the baffle. Limit control; a chain 2 is meshed with the outer wall of sprocket 2 17, and a sprocket 5 is meshed with the inner wall of the other side of the chain 2. The outer wall of sprocket 5 is rotatably connected to the upper side of the top cover 7, and a bevel gear 20 is fixedly connected to its upper end. A bevel gear 18 is meshed with the outer wall of the upper side of bevel gear 20. A reciprocating screw 22 is fixedly connected to the right side of bevel gear 18. The outer wall of the reciprocating screw 22 is rotatably connected to the inside of the support frame 4. The outer wall of the container 21 on the left side is sleeved on the reciprocating screw 22, forming a complete feeding drive transmission chain.

[0029] Working principle: Starting motor 1 causes the rotating shaft 11 and the lower stirring blade 12 to rotate, thus stirring the material inside the shell. Simultaneously, motor 1 drives sprocket 17 to rotate, which in turn drives sprocket 5 to rotate synchronously via chain 2. Sprocket 5 drives bevel gear 20 to rotate, which meshes with bevel gear 18, thereby driving reciprocating screw 22 to rotate. Under the action of reciprocating screw 22, container 21 moves back and forth. When container 21 moves to the left, its lower flap 19 disengages from the baffle on the lower side of support frame 4 and rotates downwards under gravity, causing the internal material to fall into the feeding port. At the same time, the right side of container 21 blocks the lower side of the container 3, preventing material from continuously falling. When container 21 moves to the right, flap 19 is supported and closed by the baffle again, and container 21 moves to the lower side of container 3 to complete material filling, achieving automatic quantitative feeding. In addition, when the rotating shaft 11 rotates, it drives the large gear 14 to rotate. The large gear 14 meshes with the small gear 15, and the gear ring 16 rotates through the transmission of the small gear 15. The gear ring 16 drives the stirring ring 8 to rotate through the connecting rod 9. Due to the reversing effect of the small gear 15, the stirring ring 8 and the stirring blade 12 rotate in opposite directions, which prevents the material from being squeezed into the inner wall of the shell 6 and makes the material more fully mixed.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
