Description

Technical Field

[0001] This utility model relates to the field of stirrer technology, and in particular to a stirrer with a variable angle. Background Technology

[0002] In many fields such as modern chemical engineering, pharmaceuticals, food processing, and materials science, stirring is a crucial unit process. The main purpose of stirring is to ensure that substances of different components are thoroughly mixed and achieve a uniform dispersion, thereby guaranteeing the quality and performance stability of the product. To further improve stirring efficiency, the angle of the stirring blades can be adjusted, allowing for optimization of the stirring flow field based on actual conditions when dealing with materials of varying viscosities, densities, and flowability.

[0003] In the existing technology, most multi-blade agitators use an independent plug-in method to fix the blades to the main shaft or hub. If the bolts penetrate the base of a single blade to lock it, when replacement or maintenance is required, it is necessary to untie each blade one by one, which is time-consuming, laborious and increases the difficulty of the work.

[0004] To address this issue, we propose a variable-angle stirrer. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, most multi-blade agitators use an independent plug-in method to fix the blades to the main shaft or hub. For example, if bolts penetrate the base of a single blade to lock it, when replacement or maintenance is required, it is necessary to untie the fixing of each blade one by one, which is time-consuming, laborious and increases the difficulty of the work. Therefore, a variable angle agitator is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A variable-angle stirrer includes a mounting plate, a main shaft rotatably mounted on the mounting plate, and stirring blades arranged circumferentially along the main shaft. A stirring motor connected to the main shaft is fixedly mounted on the mounting plate. The variable-angle stirrer further includes: An angle adjustment mechanism includes a hub coaxially fixed to the bottom of the main shaft, a plurality of plug-in blocks symmetrically inserted into the hub, a fixed cylinder fixed to the side of each plug-in block away from the hub, a connecting shaft fixed to one end of the stirring blade, the connecting shaft coaxially inserted into and rotating in the fixed cylinder, a plurality of first bolt holes opened on the peripheral wall of the fixed cylinder, and a plurality of second threaded holes opened on the connecting shaft corresponding to the plurality of bolt holes, the stirring blade and the fixed cylinder being fixed in position by the plurality of bolts corresponding to the plurality of first threaded holes and the plurality of second threaded holes; The reinforcement mechanism includes a reinforcement plate movably disposed between the hub and the plug block, and a hole opened in the circumference of the hub for the reinforcement plate to slide. A spring plate is fixed on the circumferential wall of the hub. One end of the reinforcement plate and one end of the spring plate are fixed with the same protrusion. A disc is rotatably disposed on the hub coaxially. Multiple irregular blocks are fixed on the annular wall of the disc, which are pressed against the multiple protrusions under the rotation of the disc.

[0007] Furthermore, one protruding end of the protrusion is an arc-shaped surface, and the irregular block has the same shape as the protrusion and has a notch for accommodating the arc-shaped surface.

[0008] Furthermore, a drive rod connected to the hub is rotatably provided at the bottom of the hub, and a hexagonal actuating block is fixed at the bottom end of the drive rod.

[0009] Furthermore, the top surface of the hub is provided with a T-shaped groove for multiple insertion blocks to be inserted and removed.

[0010] Furthermore, each of the plurality of plug-in blocks is provided with a reinforcing groove on the side near the plurality of reinforcing plates for the plurality of reinforcing plates to be inserted and fixed.

[0011] Compared with the prior art, the advantages of this utility model are: 1. This solution triggers a chain reaction mechanism by turning a disc. When the irregular block makes a circular motion, the protrusion disengages from the notch of the irregular block. The spring plate releases its elastic force and drives the reinforcing plate to disengage from the reinforcing groove through the protrusion, realizing an automated disassembly process and significantly improving the disassembly and assembly efficiency before cleaning. 2. After loosening the fixing bolts, the blades can be freely rotated to the optimal working position before being locked in place, meeting the mixing needs of diverse materials and optimizing mixing efficiency and uniformity; 3. The disc drives the irregularly shaped block to make a circular motion, which causes the irregularly shaped block to squeeze the protrusion until the protrusion is stuck in the notch of the irregularly shaped block. At the same time, the protrusion drives the reinforcing plate to insert into the reinforcing groove of the plug-in block, realizing double reinforcement of the plug-in block, significantly enhancing the vibration resistance and stability of the device in high-intensity mixing operations, and ensuring reliable operation.

Detailed Implementation

[0015] 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.

[0016] Reference Figures 1-4 A variable-angle stirrer includes a mounting plate 1, a main shaft 2 rotatably mounted on the mounting plate 1, and stirring blades 502 arranged circumferentially along the main shaft 2. A stirring motor 3 connected to the main shaft 2 is fixed on the mounting plate 1. The variable-angle stirrer also includes: Angle adjustment mechanism includes a hub 4 coaxially fixed to the bottom of the main shaft 2, a plurality of plug-in blocks 6 symmetrically inserted on the hub 4, a fixed cylinder 5 fixed on the side of the plug-in blocks 6 away from the hub 4, a connecting shaft 501 fixed at one end of the stirring blade 502, the connecting shaft 501 coaxially inserted and rotating in the fixed cylinder 5, a plurality of first bolt holes 503 are opened on the peripheral wall of the fixed cylinder 5, and a plurality of second threaded holes are opened on the connecting shaft 501 corresponding to the plurality of bolt holes 503. The stirring blade 502 and the fixed cylinder 5 are fixed in place by the plurality of bolts corresponding to the plurality of first threaded holes and the plurality of second threaded holes. In this embodiment, the knob fixing bolt 504 is turned to disengage it from the bolt hole 503. Then, the stirring blade 502 is gently moved so that it and the connecting shaft 501 can rotate freely inside the fixed cylinder 5 for angle adjustment. The fixing bolt 504 is then tightened and screwed into the corresponding bolt hole 503 to achieve a firm lock on the connecting shaft 501 and the stirring blade 502. By driving the main shaft 2 to rotate at high speed, the hub 4, with the power transmitted by the main shaft 2, drives the stirring blade 502 to rotate efficiently inside the container through the plug block 6, the fixed cylinder 5, and the connecting shaft 501. This achieves thorough and deep mixing of the material in all directions, ensuring that the mixing effect reaches the optimal state.

[0017] Reference Figure 2 and Figure 3 The reinforcement mechanism includes a reinforcement plate 702 movably disposed between the hub 4 and the plug block 6, and a hole opened on the circumference of the hub 4 for the reinforcement plate 702 to slide. A spring plate 704 is fixed on the circumferential wall of the hub 4. One end of the reinforcement plate 702 and one end of the spring plate 704 are fixed with the same protrusion 703. A disc 7 is coaxially rotatably disposed on the hub 4. Multiple irregular blocks 701 are fixed on the annular wall of the disc 7, which are pressed against the multiple protrusions 703 under the rotation of the disc 7. One end of the protrusion 703 is an arc-shaped surface. The irregular blocks 701 have the same shape as the protrusion 703 and have a notch for accommodating the arc-shaped surface.

[0018] In this embodiment, the disk 7 is driven to start rotating and enter the working state. Multiple irregularly shaped blocks 701 will move in a circular motion along the rotation trajectory of the disk 7. The irregularly shaped blocks 701 continuously compress the protrusions 703, causing them to shift until the protrusions 703 are engaged in the notches of the irregularly shaped blocks 701. Simultaneously, pressure is applied to the spring sheet 704, causing it to compress and deform. At the same time, the irregularly shaped blocks 701 will also drive the reinforcing plate 702 to smoothly insert into the pre-set reinforcing groove of the plug-in block 6, thereby achieving the reinforcement of the installed plug-in block 6. The double reinforcement effect greatly enhances its stability; conversely, when it is necessary to remove the reinforcement of the plug block 6, the disc 7 is rotated by turning it, and multiple irregular blocks 701 will make a circular motion along the rotation trajectory of the disc 7. Then the protrusion 703 will disengage from the notch of the irregular block 701, and at the same time the spring plate 704 will release the elastic force to drive the protrusion 703 to move. The reinforcement plate 702 moves and works along the trajectory of the protrusion 703 and moves away from the reinforcement groove, thereby removing the reinforcement of the plug block 6.

[0019] Reference Figure 2 and Figure 3 Each of the multiple plug-in blocks 6 has a reinforcing groove on one side near the multiple reinforcing plates 702 for inserting and fixing the multiple reinforcing plates 702.

[0020] In this embodiment, the cooperation between the reinforcing plate 702 and the reinforcing groove enables the reinforcing plate 702 to be inserted into the pre-set reinforcing groove of the plug block 6 by the irregular block 701, forming a "mortise and tenon" mechanical interlocking structure. Together with the action of the protrusion 703 being inserted into the notch, it forms a double insurance, effectively preventing loosening and falling off due to vibration or external impact.

[0021] The implementation principle of a variable-angle stirrer according to an embodiment of this application is as follows: The plug-in block 6, equipped with a fixed cylinder 5, a connecting shaft 501, and a stirring blade 502, needs to be precisely embedded into the T-shaped groove. Then, with the help of the coordinated action of the actuating block 8 and the drive rod, the disc 7 is driven to start rotating and enter the working state. At this time, multiple irregular blocks 701 will make circular motion along the rotation trajectory of the disc 7. During this process, the irregular blocks 701 continuously squeeze the protrusions 703 to displace them until the protrusions 703 are stuck in the notches of the irregular blocks 701. At the same time, pressure is applied to the spring plate 704 to compress and deform it. Meanwhile, the irregular blocks 701 will also drive the reinforcing plate 702 to smoothly insert into the pre-set reinforcing groove of the plug-in block 6, thereby achieving a double reinforcement effect on the installed plug-in block 6, greatly enhancing its stability, and providing a reliable guarantee for the subsequent stable operation of the stirring blade 502 in high-intensity stirring operations.

[0022] Next, the angle of the stirring blade 502 is flexibly adjusted according to the characteristics of the material to be stirred. In specific operation, first loosen the fixing bolt 504, then gently move the stirring blade 502 so that it and the connecting shaft 501 can rotate freely inside the fixed cylinder 5. After carefully adjusting to the most suitable angle according to the actual working conditions, tighten the fixing bolt 504 and screw it into the corresponding bolt hole 503 to achieve a firm lock on the connecting shaft 501 and the stirring blade 502. After completing the above steps, the entire device is securely placed on the container to be stirred by the mounting plate 1. When the stirring motor 3 is started, its output shaft drives the main shaft 2 to rotate at high speed. The hub 4, with the power transmitted by the main shaft 2, drives the stirring blade 502 to rotate efficiently in the container through the plug block 6, the fixed cylinder 5 and the connecting shaft 501, thereby achieving full stirring of the material in all directions and at a deep level, ensuring that the stirring effect reaches the best state.

[0023] When the stirring blade 502 finishes stirring and needs to be cleaned, the disc 7 is rotated and put into operation by turning it. At this time, multiple irregular blocks 701 will move in a ring along the rotation trajectory of the disc 7. Then, the protrusion 703 will disengage from the notch of the irregular block 701. At the same time, the spring plate 704 will release its elastic force to move the protrusion 703. Subsequently, the reinforcing plate 702 will move along the trajectory of the protrusion 703 and move away from the reinforcing groove, thereby releasing the reinforcement of the plug block 6. The plug block 6 can then be pulled out of the T-slot. Then, the fixing bolt 504 is unscrewed from the bolt hole 503, and the connecting shaft 501 with the stirring blade 502 is taken out from the fixing cylinder 5, thus completing the disassembly of the stirring blade 502.

[0024] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

[0025] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
