Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and more specifically, to a detachable fixing device for the stirring paddle of a double-mouth stuffing mixer. Background Technology

[0002] As a core piece of equipment in the food processing industry, such as the production of dumplings, buns, and meatballs, the stability of the mixing paddle of the double-mouth filling mixer directly affects the uniformity of the filling mixture and the processing efficiency. Currently, most double-mouth filling mixers on the market use a motor to drive the rotating shaft and mixing paddle to rotate and mix the filling.

[0003] Existing structures are inconvenient to move, and traditional impeller fixing devices mostly use welding or integrated structures, making it difficult to disassemble and clean the impeller blades.

[0004] A search revealed that Chinese patent CN219355907U discloses a double-auger mixing machine for even mixing. This mechanism uses a control panel to activate a motor that drives a connecting drum, causing two mixing devices to rotate and mix. The mixing blades on the drum surface are arranged in a cross pattern for thorough and even mixing. Furthermore, the mixing blades are detachable, allowing for installation or removal from the nut surface via threads on the connecting rod, facilitating cleaning after use. This design is highly practical. Additionally, a reinforcing plate on the machine's outer casing helps mitigate vibrations during operation. A storage box on the outer casing provides convenient storage for tools and other items. Finally, the pulleys at the bottom of the support plate can be secured with a foot brake when moved to a designated location, preventing the machine from shifting.

[0005] However, in actual use, the mixing blade is detachable only through the threaded connection of the connecting rod and the nut. Since the filling itself has a certain degree of stickiness, the sticky filling will adhere tightly to the surface of the mixing blade during high-speed rotation. As the mixing blade moves synchronously, it will generate additional torque along the tangential direction of the mixing blade's rotation, which will continuously act on the threaded connection between the connecting rod and the nut, causing relative rotation between the nut and the connecting rod, resulting in loosening. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a detachable fixing device for the mixing paddle of a double-mouth mixing machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A detachable fixing device for the mixing paddle of a double-mouth stuffing mixer includes a mixing shaft. Two fixing discs are fixedly mounted on the surface of the mixing shaft. Multiple limiting strips are fixedly mounted on the surface of the mixing shaft. Two arc-shaped sleeves are fitted on the surface of the limiting strips. Multiple disassembly components are provided on the surface of the arc-shaped sleeves.

[0009] The disassembly assembly includes multiple internally threaded rings fixedly disposed on the surface of the arc-shaped sleeve. The internal threads of the multiple internally threaded rings are connected to threaded posts. A connecting ring is fixedly disposed on the surface of the threaded posts. The surface of the connecting ring is provided with multiple threaded holes. The surface of the internally threaded rings is provided with multiple threaded grooves. The internal threads of the threaded holes and threaded grooves are all threadedly connected to the interior of the threaded holes and threaded grooves.

[0010] A stirring rod is fixedly installed at one end of the threaded column, and multiple stirring paddles are fixedly installed on the surface of the stirring rod.

[0011] By adopting the above technical solution, the positioning and installation of the arc sleeve on the stirring shaft can be completed quickly, laying a stable foundation for the subsequent assembly of components. Secondly, it can ensure the stability of the stirring rod and stirring paddle during operation, and also enable quick disassembly for easy maintenance and replacement.

[0012] As a further description of the above technical solution: the two fixed discs are fixedly disposed on both sides of the limiting strip, and a guide groove is provided on the surface of one of the arc-shaped sleeves;

[0013] A guide bar is inserted into the inside of the guide groove, and the guide bar is fixedly connected to the surface of another arc-shaped sleeve.

[0014] By adopting the above technical solution, the axial displacement of the arc sleeve on the stirring shaft can be precisely limited, avoiding the arc sleeve from shifting during stirring operations, ensuring the overall structural stability. Moreover, the guide groove and guide strip can be inserted and matched to quickly align the two arc sleeves, reducing positioning deviations during assembly and greatly improving the assembly efficiency of the arc sleeve.

[0015] As a further description of the above technical solution: a plurality of connecting blocks are fixedly provided on the surface of the arc-shaped sleeve, and the surface of the connecting blocks is provided with mounting grooves, and a second bolt is threaded into the mounting grooves;

[0016] The stirring paddle is made of food-grade stainless steel, and the threaded column and stirring rod are integrally formed.

[0017] By adopting the above technical solution, the two arc-shaped sleeves can be firmly locked, preventing them from loosening when the stirring shaft rotates at high speed, thus ensuring the safety and stability of the device operation.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. The disassembly component of this utility model, from the perspective of disassembly operation, uses the threaded engagement of the internal threaded ring and the threaded column, combined with the threaded hole on the connecting ring, the threaded groove on the internal threaded ring, and the combination structure of the first bolt. During disassembly, only the first bolt needs to be unscrewed, and then the threaded column needs to be unscrewed from the internal threaded ring to separate the stirring rod and the stirring paddle. Moreover, in terms of connection stability, the threaded connection itself has reliable fastening, and the second fixation of the connecting ring and the internal threaded ring by the first bolt can effectively prevent the threaded column from loosening during the stirring operation, ensuring the stable operation of the stirring rod and the stirring paddle, and guaranteeing the efficiency and quality of mixing fillings. At the same time, this component can easily replace the stirring rod and stirring paddle of different specifications according to the actual mixing needs, improving the adaptability of the device to different fillings and different mixing scenarios, extending the service life of the overall device, and bringing users an efficient and flexible user experience.

[0020] 2. In this utility model, two fixed discs are fixed on both sides of the limiting strip, which can accurately limit the axial position of the arc sleeve on the stirring shaft, prevent the arc sleeve from shifting during stirring, and provide a stable foundation for the installation of subsequent components. The guide groove and guide strip are inserted and matched, allowing the two arc sleeves to be quickly positioned when they are connected, reducing installation deviation, improving assembly efficiency, and enhancing the overall stability of the arc sleeve to prevent shaking. Moreover, the combination of the connecting block, the mounting groove and the second bolt can firmly lock the two arc sleeves, ensuring that they do not loosen when the stirring shaft is running at high speed, and ensuring the safe operation of the device.

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.

[0028] The embodiments disclosed in this application are as follows: Figure 1-3 The detachable fixing device for the mixing paddle of the double-mouth mixing machine shown includes a mixing shaft 1, two fixing plates 2 are fixedly installed on the surface of the mixing shaft 1, multiple limiting strips 3 are fixedly installed on the surface of the mixing shaft 1, two arc-shaped sleeves 4 are sleeved on the surface of the limiting strips 3, and multiple disassembly components are provided on the surface of the arc-shaped sleeves 4.

[0029] The disassembly assembly includes multiple internally threaded rings 5 ​​fixedly disposed on the surface of the arc-shaped sleeve 4. The internal threads of the multiple internally threaded rings 5 ​​are connected to threaded posts 6. The surface of the threaded posts 6 is fixedly disposed with connecting rings 7. The surface of the connecting rings 7 is provided with multiple threaded holes 8. The surface of the internally threaded rings 5 ​​is provided with multiple threaded grooves 9. The threaded holes 8 and the threaded grooves 9 are all threadedly connected with first bolts 10.

[0030] A stirring rod 11 is fixedly provided at one end of the threaded column 6, and a plurality of stirring paddles 12 are fixedly provided on the surface of the stirring rod 11;

[0031] Two arc-shaped sleeves 4 are fitted onto the surface of the limiting strip 3. During installation, attention should be paid to the guide groove 13 on the surface of one of the arc-shaped sleeves 4. The guide strip 14, which is fixedly connected to the surface of the other arc-shaped sleeve 4, should be accurately inserted into the guide groove 13. Through the cooperation between the guide groove 13 and the guide strip 14, it is ensured that the two arc-shaped sleeves 4 can be precisely aligned to form a complete wrap around the limiting strip 3.

[0032] When maintenance or replacement of the stirring rod 11 and stirring paddle 12 is required, first unscrew the first bolt 10 that is threaded into the threaded hole 8 and the threaded groove 9, and then unscrew the threaded post 6 from the inside of the inner threaded ring 5. The threaded post 6, stirring rod 11 and stirring paddle 12 can then be removed from the arc-shaped sleeve 4 for subsequent maintenance or replacement.

[0033] Reference Figure 2-3 As shown, two fixed discs 2 are fixedly installed on both sides of the limiting strip 3, and a guide groove 13 is opened on the surface of one of the arc-shaped sleeves 4;

[0034] A guide bar 14 is inserted into the guide groove 13, and the guide bar 14 is fixedly connected to the surface of another arc-shaped sleeve 4;

[0035] After the device is assembled, the double-port mixing machine is started, and the mixing shaft 1 begins to rotate. Since the mixing shaft 1 is fixedly connected to the fixed plate 2 and the limiting strip 3, and the limiting strip 3 is fixed to the arc sleeve 4, and the arc sleeve 4 is connected to the threaded column 6 and the mixing rod 11 through the quick-release fixing assembly, the rotation of the mixing shaft 1 will sequentially drive the fixed plate 2, the limiting strip 3, the arc sleeve 4, the threaded column 6, and the mixing rod 11 to rotate, and finally cause the multiple mixing paddles 12 fixed on the surface of the mixing rod 11 to rotate, and perform mixing operations on the filling.

[0036] Reference Figure 4-5 As shown, multiple connecting blocks 15 are fixedly provided on the surface of the arc-shaped sleeve 4. The surface of the connecting block 15 is provided with an installation groove 16, and the interior of the installation groove 16 is threaded with a second bolt 17.

[0037] The stirring paddle 12 is made of food-grade 304 stainless steel, and the threaded column 6 and the stirring rod 11 are integrally formed.

[0038] After the two arc-shaped sleeves 4 are precisely aligned, they are secured using multiple connecting blocks 15 fixed to the surface of the arc-shaped sleeves 4. The second bolt 17 is threaded into the mounting groove 16 on the surface of the connecting block 15. By tightening the second bolt 17, the two arc-shaped sleeves 4 are stably fixed on the limiting strip 3, thus completing the installation and fixing of the arc-shaped sleeves 4.

[0039] If maintenance is required on internal components such as the arc sleeve 4 or the stirring shaft 1, after disassembling the stirring rod 11 and the stirring paddle 12, unscrew the second bolt 17 that is threaded into the mounting groove 16 of the connecting block 15, and then pull the guide strip 14 out of the guide groove 13. This will allow the two arc sleeves 4 to be removed from the surface of the limiting strip 3, and then the relevant components can be maintained.

[0040] The mixing paddle 12 is made of food-grade 304 stainless steel, which ensures that the filling will not be contaminated during the mixing process. At the same time, the threaded column 6 and the mixing rod 11 are integrally formed, which enhances the stability and durability during the mixing process.

[0041] Working principle of this utility model:

[0042] This utility model is a detachable fixing device for the mixing paddle of a double-mouth stuffing machine. When in use, the two fixing discs 2 are accurately fixed on both sides of the limiting strip 3 to ensure the accurate position of the arc sleeve 4 during subsequent installation.

[0043] Then, the two arc-shaped sleeves 4 are placed on the surface of the limiting strip 3. During the installation process, attention should be paid to the guide groove 13 opened on the surface of one of the arc-shaped sleeves 4. The guide strip 14 fixedly connected to the surface of the other arc-shaped sleeve 4 is accurately inserted into the guide groove 13. Through the cooperation of the guide groove 13 and the guide strip 14, it is ensured that the two arc-shaped sleeves 4 can be precisely connected to form a complete wrapping of the limiting strip 3.

[0044] Next, after the two arc-shaped sleeves 4 are precisely aligned, multiple connecting blocks 15 fixedly installed on the surface of the arc-shaped sleeves 4 are used for fixing. The second bolt 17 is threaded into the mounting groove 16 opened on the surface of the connecting block 15. By tightening the second bolt 17, the two arc-shaped sleeves 4 are stably fixed on the limiting strip 3, thus completing the installation and fixing of the arc-shaped sleeves 4.

[0045] Then, the threaded column 6 is threaded to the inside of the internal threaded ring 5 fixed on the surface of the arc sleeve 4. Then, the position of the connecting ring 7 is adjusted so that the multiple threaded holes 8 on the surface of the connecting ring 7 correspond to the multiple threaded grooves 9 on the surface of the internal threaded ring 5. Then, the first bolt 10 is threaded to the inside of the threaded holes 8 and the threaded grooves 9 respectively. By tightening the first bolt 10, a stable connection between the threaded column 6 and the internal threaded ring 5 is achieved. An elastic washer is provided between the connecting ring 7 and the threaded ring 5 to further enhance the anti-loosening effect of the threaded connection and adapt to long-term high-frequency stirring operation.

[0046] Since a stirring rod 11 is fixedly installed at one end of the threaded column 6, and multiple stirring paddles 12 are fixedly installed on the surface of the stirring rod 11, the stirring rod 11 and the stirring paddles 12 have completed their fixed installation with the arc sleeve 4, and the entire device is assembled.

[0047] After the device is assembled, the double-port mixing machine is started, and the mixing shaft 1 begins to rotate. Since the mixing shaft 1 is fixedly connected to the fixed plate 2 and the limiting strip 3, and the limiting strip 3 is fixed to the arc sleeve 4, and the arc sleeve 4 is connected to the threaded column 6 and the mixing rod 11 through the quick-release fixing component, the rotation of the mixing shaft 1 will sequentially drive the fixed plate 2, the limiting strip 3, the arc sleeve 4, the threaded column 6, and the mixing rod 11 to rotate, and finally cause the multiple mixing paddles 12 fixed on the surface of the mixing rod 11 to rotate. The mixing paddles 12 are arc-shaped, which can improve the uniformity of the filling mixture and perform mixing operations. Moreover, the mixing paddles 12 are made of food-grade 304 stainless steel, which can ensure that the filling will not be contaminated during the mixing process. At the same time, the threaded column 6 and the mixing rod 11 are integrally formed, which enhances the stability and durability during the mixing process.

[0048] When maintenance or replacement of the stirring rod 11 and stirring paddle 12 is required, first unscrew the first bolt 10 that is threaded into the threaded hole 8 and the threaded groove 9, and then unscrew the threaded column 6 from the inside of the inner threaded ring 5. The threaded column 6, stirring rod 11 and stirring paddle 12 can then be removed from the arc-shaped sleeve 4 for subsequent maintenance or replacement.

[0049] If maintenance is required on internal components such as the arc sleeve 4 or the stirring shaft 1, after disassembling the stirring rod 11 and the stirring paddle 12, unscrew the second bolt 17 threaded into the mounting groove 16 of the connecting block 15, and then pull the guide strip 14 out of the guide groove 13. This will allow the two arc sleeves 4 to be removed from the surface of the limiting strip 3, and the relevant components to be maintained.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
