Description
Technical Field
[0001] This utility model relates to the field of mixing equipment technology, specifically a high-efficiency and energy-saving multi-axis linkage mixing equipment for coating mixing. Background Technology
[0002] During the mixing process of paint, a stirring device is needed to mix the paint evenly, so that the mixed paint can be sprayed or coated on the object.
[0003] For example, patent CN222900786U discloses a mixing and stirring device for processing coatings, including a mixing cylinder, stirring plates with different inclination angles, and vertical rods and stirring rods that rotate in the opposite direction to the stirring plates. It can stir and mix the coatings in different directions and positions, which can greatly improve the mixing effect and efficiency of the liquid. At the same time, the connecting plate can scrape the bottom of the mixing cylinder to prevent sedimentation and accumulation. However, when using the stirring device, because the stirring device can clean the bottom of the cylinder, it neglects the side walls of the cylinder, resulting in coatings adhering to the side walls of the cylinder. It also cannot stir the upper and lower layers or different positions, affecting the uniformity of the stirring.
[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing high-efficiency, energy-saving, multi-shaft linkage mixing equipment for coatings. Utility Model Content
[0005] The purpose of this utility model is to provide a high-efficiency and energy-saving multi-axis linkage mixing device for coating mixing, so as to solve the problem mentioned in the background art that when using the mixing device, the mixing device can clean the bottom of the cylinder but neglects the side wall of the cylinder, resulting in coating adhering to the side wall of the cylinder, and the inability to mix the upper and lower layers and different positions, thus affecting the uniformity of mixing.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving multi-shaft linkage mixing device for coating mixing, comprising a mixing drum, a drive cover installed on the top of the mixing drum, a top cover installed on the top of the drive cover, a drive motor installed on the top of the top cover via a bracket, and a discharge port provided at the bottom of the mixing drum; a quadrangular prism installed at the output end of the drive motor, a stirring shaft sleeved on the outer wall of the quadrangular prism, and a first stirring blade installed on the outer wall at the bottom end of the stirring shaft; and a cleaning mechanism for cleaning the inner wall of the mixing drum provided at the bottom of the drive cover.
[0007] Furthermore, the cleaning mechanism includes a protective sleeve, which is fixedly connected to the bottom of the drive cover. A U-shaped frame is installed inside the protective sleeve, and the stirring shaft is rotatably connected to the inner wall of the U-shaped frame. A first bevel gear is installed on one side of the U-shaped frame, and second bevel gears mesh with each other on the upper and lower sides of the first bevel gear.
[0008] Furthermore, the interior of the second bevel gear on one side is fixedly connected to the stirring shaft, and the interior of the U-shaped frame is rotatably connected to a rotating shaft. The second bevel gear on the other side is fixedly connected to the outer wall of the rotating shaft, and scrapers are fixedly connected to both sides of the bottom end of the rotating shaft. The inner wall of the rotating shaft is rotatably connected to the outer wall of the stirring shaft.
[0009] Furthermore, the drive cover is equipped with a stirring mechanism for multi-directional stirring of materials. The stirring mechanism includes a cross connecting rod, which is fixedly connected to the outer wall of the stirring shaft. A gear ring is installed at the bottom of the cross connecting rod, and the gear ring is rotatably connected to the inside of the drive cover. Three sets of internal gears are meshed on the inner side of the gear ring.
[0010] Furthermore, a rotating column is fixedly connected inside the internal gear, and four sets of second stirring blades are installed on the outer wall of the rotating column. The rotating column is rotatably connected to the drive cover.
[0011] Furthermore, screws are installed around the inside of the top cover, and the threaded end of the screws is threadedly connected to the drive cover.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This coating mixing equipment uses a high-efficiency and energy-saving multi-shaft linkage mixing device. When the mixing shaft rotates, not only does the first mixing blade at its bottom perform preliminary mixing of the coating, but it also drives the rotating shaft and rotating column to rotate through the gear transmission of the mixing mechanism. The scraper on the rotating shaft rotates in the opposite direction to the first mixing blade, stirring the material in the opposite direction, making the material more uniformly mixed. The second mixing blade on the rotating column works in conjunction with the first mixing blade to achieve uniform mixing of the upper and lower layers of the mixing drum. This enables the mixing components at different positions to work together, greatly improving the mixing uniformity of the coating.
[0013] Furthermore, during the mixing process, the scraper cleans the inner wall of the mixing drum to prevent the coating from adhering to the drum wall and ensure the cleanliness of the mixing container. On the other hand, the counter-current movement of the scraper and the first mixing blade creates convection, which increases the shear force of the material, allowing the material to be mixed more thoroughly during the mixing process, thereby further improving the mixing effect.
[0014] Furthermore, the top cover and the drive cover are firmly connected by screws, which enables the components to operate stably during the stirring process. At the same time, the cooperation between the four-sided prism and the stirring shaft, as well as the meshing between the gears, not only allows the drive motor to drive the stirring shaft smoothly, but also helps to quickly disassemble the top cover to inspect and repair the internal parts of the drive cover.

Detailed Implementation
[0022] 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.
[0023] Example 1: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6This utility model provides the following technical solution: a high-efficiency and energy-saving multi-shaft linkage mixing device for coating mixing, including a mixing drum 1, a drive cover 2 installed on the top of the mixing drum 1, a top cover 3 installed on the top of the drive cover 2, a drive motor 4 installed on the top of the top cover 3 via a bracket, and a discharge port provided at the bottom of the mixing drum 1; a quadrangular prism 9 is installed at the output end of the drive motor 4, a stirring shaft 5 is sleeved on the outer wall of the quadrangular prism 9, and a first stirring blade 6 is installed on the outer wall at the bottom end of the stirring shaft 5; a cleaning mechanism for cleaning the inner wall of the mixing drum 1 is provided at the bottom of the drive cover 2; the cleaning mechanism includes a protective sleeve 10, and the protective sleeve 1... The protective sleeve 10 is fixedly connected to the bottom of the drive cover 2. A U-shaped frame 11 is installed inside the protective sleeve 10. The stirring shaft 5 is rotatably connected to the inner wall of the U-shaped frame 11. A first bevel gear 13 is installed on one side of the U-shaped frame 11. A second bevel gear 12 meshes with the upper and lower sides of the first bevel gear 13. The interior of the second bevel gear 12 on one side is fixedly connected to the stirring shaft 5. A rotating shaft 14 is rotatably connected inside the U-shaped frame 11. The second bevel gear 12 on the other side is fixedly connected to the outer wall of the rotating shaft 14. Scrapers 8 are fixedly connected to both sides of the bottom end of the rotating shaft 14. The inner wall of the rotating shaft 14 is rotatably connected to the outer wall of the stirring shaft 5.
[0024] When using the device for stirring, such as Figure 1 and Figure 2 As shown, firstly, the drive motor 4 is started. After the drive motor 4, which is installed on the top of the top cover 3, is started, its output end will drive the quadrangular prism 9 to rotate, as shown. Figure 5 As shown, since the outer wall of the quadrangular prism 9 is fitted with a stirring shaft 5, the rotation of the quadrangular prism 9 will cause the stirring shaft 5 to rotate synchronously through the interaction between the prisms on the quadrangular prism 9 itself and the stirring shaft 5. Figure 3 As shown, a first stirring blade 6 is installed on the outer wall of the bottom end of the stirring shaft 5. Therefore, when the stirring shaft 5 rotates, the first stirring blade 6 rotates accordingly, performing preliminary stirring of the coating material in the stirring drum 1. When the stirring shaft 5 rotates, as... Figure 6As shown, since the U-shaped frame 11 is rotatably connected to the stirring shaft 5 and is directly fixed to the drive cover 2, and the second bevel gear 12 on one side is fixedly connected to the stirring shaft 5, when the stirring shaft 5 rotates, it will drive the second bevel gear 12 on one side to rotate synchronously. At this time, the U-shaped frame 11 will not rotate, and the rotation of the second bevel gear 12 will drive the first bevel gear 13 meshing with it to rotate. The first bevel gear 13 then meshes with the second bevel gear 12 on the other side, thereby driving the second bevel gear 12 on the other side to rotate. Shaft 14 is fixedly connected, so when the second bevel gear 12 rotates, it will drive the rotating shaft 14 to rotate synchronously. The two second bevel gears 12 will reverse direction under the action of the first bevel gear 13, so that the rotation direction of the stirring shaft 5 and the rotating shaft 14 is opposite. Since the bottom end of the rotating shaft 14 is equipped with a scraper 8, when the rotating shaft 14 rotates, it will drive the scraper 8 to clean the inner wall of the stirring drum 1. Since the scraper 8 and the first stirring blade 6 on the stirring shaft 5 rotate in opposite directions, the scraper 8 and the first stirring blade 6 will stir in opposite directions when they move, which can make the material more evenly stirred.
[0025] Example 2: Please refer to Figure 3 and Figure 4 Based on Embodiment 1, a stirring mechanism is also disclosed, the specific structure of which is as follows: The stirring mechanism includes a cross connecting rod 15, which is fixedly connected to the outer wall of the stirring shaft 5. A gear ring 16 is installed at the bottom of the cross connecting rod 15, and the gear ring 16 is rotatably connected to the inside of the drive cover 2. Three sets of internal gears 17 are meshed on the inner side of the gear ring 16. A rotating column 18 is fixedly connected inside the internal gear 17. Four sets of second stirring blades 19 are installed on the outer wall of the rotating column 18, and the rotating column 18 is rotatably connected to the drive cover 2. Screws 20 are installed around the inside of the top cover 3, and the threaded end of the screws 20 is threadedly connected to the drive cover 2.
[0026] When the stirring shaft 5 rotates, as Figure 3 As shown, since the cross connecting rod 15 is fixedly connected to the outer wall of the stirring shaft 5, the rotation of the stirring shaft 5 will drive the cross connecting rod 15 to rotate. A gear ring 16 is installed at the bottom of the cross connecting rod 15, and the gear ring 16 is rotatably connected to the inside of the drive cover 2. Therefore, the rotation of the cross connecting rod 15 drives the gear ring 16 to rotate within the drive cover 2. Figure 3 and Figure 4As shown, since three sets of internal gears 17 are meshed on the inner side of the gear ring 16, when the gear ring 16 rotates, it drives the three sets of internal gears 17 to rotate through the meshing action with the internal gears 17. Since the internal gears 17 have rotating columns 18 installed inside, the rotation of the internal gears 17 will drive the rotating columns 18 to rotate. Since four sets of second stirring blades 19 are installed on the outer wall of the rotating columns 18, when the rotating columns 18 rotate, the second stirring blades 19 rotate accordingly. At this time, the first stirring blades 6 and the second stirring blades 19 cooperate with each other to achieve uniform stirring of the upper and lower layers of the mixing drum 1, realizing multi-axis linkage stirring of the coating in the mixing drum 1, improving the mixing uniformity and stirring efficiency of the coating. Since screws 20 are installed around the inside of the top cover 3, and the threaded end of the screws 20 is threaded to the drive cover 2, by tightening the screws 20, the top cover 3 and the drive cover 2 can be firmly connected to ensure the stability of the equipment structure.
