[0001] The utility model relates to the technical field of high-speed mixer main shafts, in particular to a high-speed mixer main shaft structure. Background Art

[0002] High-speed mixer is a mechanical device used to mix two or more different substances evenly. It mainly uses high-speed rotating stirring blades to fully mix different substances, thereby achieving a uniform mixing effect. High-speed mixer has the advantages of efficient mixing, rapid stirring and strong adjustability.

[0003] During the use of the high-speed mixer, some materials tend to agglomerate and harden on the surface of the stirring blades, which requires staff to clean and maintain them regularly. In the existing high-speed mixers, the stirring blades are mostly fixed to the main shaft by bolts. When disassembling and assembling, specific tools are required to remove the bolts, and after installation, the bolts need to be tightened again. The operation process is relatively cumbersome, time-consuming and labor-intensive. In view of this, we propose a high-speed mixer main shaft structure to solve the above problems. Utility Model Content

[0006] Furthermore, the limiting sleeve is sleeved on the outside of the fixing rod, and the sliding block is a square block and is slidably connected to the inner wall of the limiting sleeve.

[0007] Furthermore, one end of the rotating rod away from the limiting sleeve extends to the center of the stirring blade set, and a sealing plug is clamped on the top of the stirring blade set.

[0008] Furthermore, an opening matched with the positioning block is formed on the surface of the clamping rod, and the movable rod is slidably connected to the inner wall of the installation cavity.

[0009] Furthermore, the connection cover is an L-shaped ring, and the stirring blade kit is installed on the top of the connection cover and fixed to the main shaft body through a limiting component.

[0014] The main shaft structure of the high-speed mixer can complete the installation of the stirring blade kit by installing the stirring blade kit on the connecting cover and then limiting the stirring blade kit through the limiting piece. During operation, it is only necessary to pull the rotating rod to make the clamping rod disengage from the positioning block, and then rotate the rotating rod to make the turntable drive the two connecting rods to deflect, so that the two limiting plates can move in relative or opposite directions. The stirring blade kit can be limited by the two limiting plates, thereby realizing the disassembly and assembly of the stirring blade kit.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 and Figure 2 A high-speed mixer main shaft structure includes a main shaft body 1, a mounting cavity 3 and a stirring blade kit 2, and a connecting cover 18 is fixedly installed on the surface of the main shaft body 1.

[0024] The mounting cavity 3 is located inside the spindle body 1 .

[0025] See also Figure 3 , Figure 4 and Figure 5 A limiting member for limiting the stirring blade kit 2 is arranged inside the installation cavity 3, and the limiting member includes a turntable 4 rotatably installed on the bottom wall of the installation cavity 3, and two limiting rods 5 are fixedly installed on the top of the turntable 4, and connecting rods 6 are rotatably installed on the surfaces of the two limiting rods 5, and a movable rod 7 is rotatably installed on the other end of the connecting rod 6, and a limiting plate 8 is fixedly installed on the other side of the movable rod 7. A limiting groove 9 adapted to the limiting plate 8 is also opened on the inner wall of the stirring blade kit 2, a fixing rod 10 is also fixedly installed on the top of the turntable 4, and a slider 11 is fixedly installed on the top of the fixing rod 10, and a limiting sleeve 12 is sleeved on the outside of the slider 11, and a rotating rod 13 extending to the outside of the main shaft body 1 is also fixedly installed on the top of the limiting sleeve 12, and two clamping rods 15 are fixedly installed on the surface of the limiting sleeve 12, and four L-shaped positioning blocks 16 are fixedly installed on the inner wall of the installation cavity 3.

[0026] Among them, pulling the rotating rod 13 upwards makes the limit sleeve 12 move upwards. When the clamping rod 15 is separated from the positioning block 16, the rotating rod 13 is rotated to make the limit sleeve 12 rotate, thereby making the turntable 4 rotate. When the turntable 4 rotates, the two connecting rods 6 will move toward the outside of the turntable 4, thereby making the two limit plates 8 move in opposite directions. When the limit plate 8 is inserted into the inside of the limit groove 9, the stirring blade kit 2 is limited. At this time, the two clamping rods 15 are inserted into the other two positioning blocks 16 to limit the turntable 4. The operation process is simple and does not require the use of tools, saving time and effort.

[0027] In addition, the limiting sleeve 12 is sleeved on the outside of the fixing rod 10, and the slider 11 is a square block and is slidably connected to the inner wall of the limiting sleeve 12, so that when the rotating rod 13 rotates, it will drive the limiting sleeve 12 to rotate through the slider 11, thereby rotating the turntable 4.

[0028] At the same time, an opening matched with the positioning block 16 is formed on the surface of the clamping rod 15 , and the movable rod 7 is slidably connected to the inner wall of the installation cavity 3 .

[0029] It is worth noting that by limiting the clamping rod 15 through the positioning block 16, the turntable 4 is not likely to automatically deflect and affect the stability of the stirring blade kit 2 after installation.

[0030] See also Figure 4 In this embodiment, one end of the rotating rod 13 away from the limiting sleeve 12 extends to the center of the stirring blade set 2, and a sealing plug 14 is clamped on the top of the stirring blade set 2.

[0031] The sealing plug 14 is used to seal the connection between the rotating rod 13 and the stirring blade set 2, so that the material is not easy to enter the inner side of the stirring blade, which increases the difficulty of subsequent cleaning.

[0032] See also Figure 4 In this embodiment, the connecting cover 18 is an L-shaped ring, the stirring blade kit 2 is installed on the top of the connecting cover 18 and is fixed to the main shaft body 1 through a limit assembly, and a sealing ring 17 is also fixedly installed on the inner side of the connecting cover 18. The sealing ring 17 is located between the outer wall of the stirring blade kit 2 and the inner wall of the connecting cover 18, and one side of the surface of the sealing ring 17 is inclined.

[0033] Among them, the tightness of the connection between the connecting cover 18 and the stirring blade kit 2 is improved by setting the sealing ring 17, and one side of the surface of the sealing ring 17 is inclined to facilitate the insertion of the stirring blade kit 2 into the interior of the connecting cover 18.

[0034] See also Figure 3 and Figure 6In this embodiment, two connecting grooves 21 are provided on the surface of the main shaft body 1, and the limit plate 8 is located on the inner wall of the connecting groove 21. The main shaft body 1 is rotatably mounted on the inner wall 22 of the mixing box through the bearing 20. A sealing sleeve 19 is also fixedly mounted at the connection between the main shaft body 1 and the inner wall 22 of the mixing box, and the main shaft body 1 is rotatably connected to the inner wall of the sealing sleeve 19.

[0035] The connection groove 21 is provided so that the existence of the limiting plate 8 makes it difficult for the stirring blade kit 2 to be connected to the connection cover 18 , while also facilitating the stirring blade kit 2 to be sleeved onto the surface of the main shaft body 1 .

[0036] In addition, the sealing sleeve 19 is provided to improve the sealing performance when the main shaft body 1 is connected to the inner wall 22 of the mixing box.

[0037] When the present embodiment is in use, the stirring blade kit 2 is placed on the surface of the connecting cover 18, and the rotating rod 13 is pulled upward to make the limiting sleeve 12 move upward. When the clamping rod 15 is separated from the positioning block 16, the rotating rod 13 is rotated to make the limiting sleeve 12 rotate, thereby making the turntable 4 rotate. When the turntable 4 rotates, the two connecting rods 6 will move toward the outside of the turntable 4, thereby making the two limiting plates 8 move in opposite directions. When the limiting plates 8 are inserted into the inside of the limiting groove 9, the stirring blade kit 2 is limited. At this time, the two clamping rods 15 are inserted into the other two positioning blocks 16 to limit the turntable 4, and then the sealing plug 14 is plugged. On the contrary, when the two connecting rods 6 move toward the inner side of the surface of the turntable 4, the two limiting plates 8 move in opposite directions. When the limiting plates 8 are separated from the limiting groove 9, the stirring blade kit 2 is no longer limited. Therefore, the stirring blade kit 2 can be removed for cleaning and maintenance. The operation process is simple and does not require the use of tools, which saves time and effort, and greatly improves the efficiency of cleaning and maintenance of the stirring blade kit 2.

[0038] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0039] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
