[0002] The mixing blades of zero-gravity mixers are difficult to maintain or replace once damaged.

[0003] The main reason is that the stirring blades and connecting structure in the zero-gravity mixer are the same as those in most mixers. They are fixedly connected to the rotating shaft by welding, or the connection between the stirring blades and the shaft may be cumbersome. However, when the stirring blades and connecting structure are damaged during the mixing process, the stirring blades need to be maintained or replaced. But when the stirring blades and connecting structure are an integrated structure, it is difficult to remove the stirring blades from the shaft for maintenance or replacement.

[0004] Therefore, it is necessary to achieve the disassembly and assembly of the stirring blades and the main shaft while maintaining a high-strength connection between the stirring blades and the main shaft. Utility Model Content

The second screw passes through the external base and is threadedly connected to the external plate, and the external plate and the external base are fixedly connected.

[0008] The top of the outer plate is also interference-fitted into the rear frame. The first screw passes through the rear frame and is threadedly connected to the outer plate, thus fixing the outer plate to the rear frame.

[0009] As a preferred technical solution of this utility model, the bottom of the outer plate is trapezoidal in shape.

[0010] As a preferred technical solution of this utility model, the front end of the rear frame is fixedly connected with a stirring blade, and the top end of the rear frame is provided with an external protrusion ring, in which the first screw is inserted.

[0025] 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.

[0026] Please see Figure 1-4 A dual-shaft structure for stirring in a zero-gravity mixer includes two main shafts 1. One end of each shaft passes through the mixer housing and connects to a motor inside the power chamber. The other end is movably mounted on the mixer housing via a bearing. When the zero-gravity mixer starts, the motor inside the power chamber rotates, driving the two main shafts 1 to rotate. Simultaneously, stirring blades 3 follow the rotation to mix the materials. An external base 2 is fixedly installed on the outer side of the main shafts 1. An external plate 32 is inserted into the external base 2. The top of the external plate 32 is inserted into a rear frame 31. The front end of the rear frame 31 is fixedly connected to the stirring blades 3. An external protruding ring 34 is formed at the top of the rear frame 31. A first screw 35 is provided inside the external protruding ring 34 and is inserted into the external plate 32. The bottom of the external plate 32 is trapezoidal in shape. The outer end is inserted into the inclined slot 21 through an interference fit, which enhances the connection strength between the outer plate 32 and the outer base 2. The top of the outer plate 32 is also inserted into the rear frame 31 through an interference fit. Compared with the completely fixed connection between the outer plate 32 and the outer base 2, when the stirring blade 3 or the outer plate 32 is damaged or needs maintenance, the second screw 23 can be removed from the fixed ring frame 22, and the outer plate 32 can be pulled out from the inclined slot 21. Then the first screw 35 can be removed from the outer protruding ring 34, so that the stirring blade 3 together with the rear frame 31 and the outer plate 32 can be separated from each other. When the stirring blade 3 or the outer plate 32 is damaged or needs maintenance, the stirring blade 3 or the outer plate 32 can be removed for maintenance or replacement. The maintenance and replacement of the stirring blade 3 or the outer plate 32 is more flexible, avoiding the need to replace the entire matching main shaft 1.

[0027] Furthermore, the external convex ring 34 is threadedly connected to the first screw 35, and the top end of the first screw 35 is placed outside the external convex ring 34. At the same time, the first screw 35 is threadedly connected to the outer plate 32, which can place the connection between the rear frame 31 and the outer plate 32 on the back of the stirring blade 3, so as to avoid affecting the stirring effect of the stirring blade 3.

[0028] Furthermore, the external base 2 has an inclined slot 21 inside, and a fixing ring frame 22 is fixedly installed on the top of the external base 2. The fixing ring frame 22 has a second screw 23 inside.

[0029] Furthermore, the bottom end of the external plate 32 is inserted into the inclined slot 21, and the bottom of the external plate 32 is provided with a mating threaded hole 33, and the second screw 23 is threadedly connected to the mating threaded hole 33.

[0030] Furthermore, the bottom width of the external board 32 is smaller than the top width of the external board 32, which makes it easier for the external board 32 to be inserted into the angled slot 21.

[0031] Furthermore, the inclined slot 21 is tilted within the external base 2, and the external plate 32 is also tilted and inserted into the inclined slot 21. This tilted design allows the external plate 32 to better engage with the external base 2, enhancing the stability of the connection. When a large impact force is generated during stirring, the tilted engagement method can better disperse the force and prevent the external plate 32 from easily coming off.

[0032] Furthermore, the stirring blade 3 has an outwardly extending trapezoidal structure, and every two stirring blades 3 on the same side are parallel to each other. This shape design can increase the contact area between the stirring blade 3 and the material, thereby improving the stirring efficiency when the stirring blade 3 is stirring.

[0033] Furthermore, the external base 2 and the main shaft 1 are integrally molded, resulting in a high connection strength between them. After the external base 2 and the main shaft 1 are formed as a whole, the stirring blade 3, when inserted into the external base 2, is equivalent to being indirectly inserted into the main shaft 1, creating a near-integral structure. This design ensures a high connection strength between the two. After the integral molding, the stirring blade 3, when inserted into the external base 2, is equivalent to being indirectly inserted into the main shaft 1, guaranteeing the stability and reliability of the stirring structure. During the stirring process, it can better withstand the impact and friction of materials, extending the service life of the equipment.

[0034] Working principle: This utility model discloses a dual-shaft structure for mixing in a zero-gravity mixer. When the zero-gravity mixer is started, the motor inside the power chamber starts to run, driving the two main shafts 1 to rotate. At the same time, the mixing blades 3 follow the rotation to mix the materials. When one of the mixing blades 3 or the outer plate 32 is damaged or needs maintenance, the second screw 23 is removed from the fixed ring frame 22, the outer plate 32 can be pulled out from the inclined slot 21, and the first screw 35 is removed from the external protruding ring 34, so that the mixing blade 3 together with the rear frame 31 and the outer plate 32 are separated from each other. When the mixing blade 3 or the outer plate 32 is damaged or needs maintenance, the mixing blade 3 or the outer plate 32 can be removed for maintenance or replacement.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
