Description

Technical Field

[0001] The utility model relates to the technical field of stirring shaft supports, and particularly relates to a stirring shaft support structure for shock absorption and noise reduction. Background Art

[0002] A mixing device utilizes a mixer to generate a certain cycle, enabling the gases, liquids, and even suspended particles in the solution within the mixing device container to be mixed and homogenized. The mixer generally includes a mixing shaft and mixing blades provided on the mixing shaft. One end of the mixing shaft is connected to a speed reduction mechanism, and the other end of the mixing shaft extends into the interior of the mixing device container. In order to prevent the extended end of the mixing shaft from shaking and being eccentric, a support structure needs to be provided to support and position the extended end of the mixing shaft.

[0003] For example, a support structure for the extended end of a mixing shaft provided in a Chinese patent application with the application number 201822196852.9 includes a fixed base, a movable base, a nylon bushing, and a cover plate. One end of the fixed base passes through the wall of the supporting mixing device container and is fixed. The other end of the fixed base is provided with a flange. The fixed base is provided with a through assembly hole. The movable base is provided with a through mounting hole, and a radially extending limiting mechanism is provided in the mounting hole. The extending length of the limiting mechanism is less than the thickness of the nylon bushing. The movable base is in transitional fit in the assembly hole of the fixed base and is position-limited. The nylon bushing is assembled in the mounting hole of the movable base. The cover plate is connected to the flange of the fixed base through a flange and cooperates with the limiting mechanism to limit the position of the nylon bushing. The technical solution has a simple structure and is convenient to use. Maintenance is carried out outside the mixing device container, effectively reducing the labor intensity of workers and ensuring the production safety of enterprises.

[0004] However, the following problems still exist in this technical solution: In this technical solution, the fixed base is fixed to the wall of the supporting mixing device container by circumferential full welding. When the fixed base is damaged, the fixed base cannot be disassembled from the wall of the mixing device container for replacement, making it impossible to continue to be used.

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0024] The present utility model provides a shock-absorbing and noise-reducing stirring shaft support structure as Figures 1-5 shown, including a fixed base 1 communicated with the bottom of the stirring device. A fixing mechanism 2 is provided at the bottom of the stirring device to facilitate the disassembly of the fixed base 1. The movable base 3 is threadedly connected inside the fixed base 1. The nylon base 4 is inserted inside the movable base 3. A rubber pad 5 is provided inside the nylon base 4. The stirring shaft inside the stirring device is inserted inside the rubber pad 5. A plurality of first threaded holes 6 are opened at the bottom of the movable base 3. A plurality of second threaded holes 7 are opened at the bottom of the nylon base 4. The same first bolt 8 is threadedly connected inside the connected first threaded holes 6 and second threaded holes 7;

[0025] As Figure 3 shown, the fixing mechanism 2 includes a fixing cylinder 201 fixedly arranged at the bottom of the stirring device. Plug rods 202 are inserted into both sides of the fixing cylinder 201. Plug holes 203 are opened on both sides of the top end of the fixing base 1. The plug holes 203 are adapted to the plug rods 202. Connecting plates 205 are fixedly arranged at the ends of the two plug rods 202 away from each other. Two springs 204 are fixedly arranged on the side of the connecting plate 205 close to the fixing base 1. The ends of the springs 204 away from the connecting plate 205 are fixedly connected to the fixing base 1. Handles 206 are fixedly arranged on the sides of the two connecting plates 205 away from each other;

[0026] Pull the handle 206. The handle 206 drives the connecting plate 205 to move. The plug rod 202 is pulled out of the fixing cylinder 201 by using the connecting plate 205. Then the fixing base 1 is inserted into the fixing cylinder 201. Release the handle 206. The spring 204 on one side of the connecting plate 205 drives the plug rod 202 to move by its own elasticity, and the plug rod 202 is inserted into the plug hole 203 to fix the fixing base 1 inside the fixing cylinder 201. Then rotate the movable base 3 and rotate the movable base 3 into the fixing base 1. Then insert the nylon base 4 into the movable base 3. Rotate the first bolt 8 and rotate the first bolt 8 into the first threaded hole 6 and the second threaded hole 7. The nylon base 4 is fixed on the movable base 3 through the first bolt 8. Insert the stirring shaft into the nylon base 4;

[0027] In the present utility model, the rubber pad 5 inside the nylon base 4 is widely used in aspects such as shock absorption, buffering, sound insulation and noise reduction due to its good stability and elasticity. The present utility model can shock-absorb the stirring shaft through the rubber pad 5, and can also prevent the sound generated during the rotation of the stirring shaft from disturbing the residents, and prolongs the service life of the present utility model.

[0028] When the fixing base 1 is damaged and needs to be replaced, pull the handle 206, and pull the plug rod 202 out of the plug hole 203 on the fixing base 1 by using the handle 206. Then pull the fixing base 1, and the fixing base 1 can be taken out of the fixing cylinder 201, which is convenient for replacing the fixing base 1 and prolongs the service life of the present utility model.

[0029] As Figure 5 shown, a fixing plate 9 is fixedly arranged at the bottom of the rubber pad 5. The bottom of the fixing plate 9 penetrates through the nylon base 4 and extends out of the bottom of the nylon base 4. A support plate 10 is fixedly arranged at the bottom of the fixing plate 9. Fourth threaded holes 11 are opened on both sides of the support plate 10. A plurality of fifth threaded holes 12 are opened at the bottom of the nylon base 4. The same second bolt 13 is threadedly connected inside the connected fourth threaded hole 11 and fifth threaded hole 12;

[0030] Due to the long-term friction between the stirring shaft and the rubber pad 5, the rubber pad 5 is prone to damage. When the rubber pad 5 needs to be replaced, rotate the second bolt 13 to turn the second bolt 13 out of the fourth threaded hole 11 and the fifth threaded hole 12, and use the support plate 10 to pull the rubber pad 5 out of the nylon base 4, then the rubber pad 5 can be replaced, which extends the service life of the present utility model.
