[0002] A vermicelli dough mixer is a core piece of equipment specifically designed for making vermicelli. Its main function is to mix starch (such as sweet potato, potato, cassava, etc.) with water and additives (such as alum, edible alkali) into a uniform dough, providing the basic raw materials for subsequent extrusion molding.

[0003] Spiral mixing is a common mixing method in noodle and dough mixing machines. The spiral hook is driven by the transmission device to rotate in the mixing cylinder. The raw materials are continuously pushed, pulled, kneaded and pressed in the cylinder to fully mix them and prevent them from hardening and clumping.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN222815160U discloses "a bidirectional stirring hook for a dough mixer", which includes: a transmission pulley: a rotating shaft is coaxially fixed thereon, and a transmission gear is coaxially fixed on the other side of the rotating shaft; a first stirring hook: the first stirring hook is in the shape of a double-arm spiral, a first fixed seat is fixed at the upper end of the first stirring hook, the projection of the first fixed seat is circular, a first rotating shaft is coaxially fixed to the first fixed seat, a first gear is coaxially fixed to the first rotating shaft, and the first gear meshes with the transmission gear.

[0040] 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.

[0041] Please see Figures 1-6 This utility model provides the following technical solution: a noodle and dough mixer anti-caking stirring paddle, comprising: two spaced transmission rods 1, a stirring paddle body 3 with a spiral structure mounted on the transmission rods 1, and a linkage assembly 4 that drives the two transmission rods 1 to rotate synchronously. It also includes a detachable connection structure, which comprises: two fixed discs 2 spaced apart on the transmission rods 1, fixed blocks 31 fixed at both ends of the stirring paddle body 3, a positioning screw 5 fixed to the fixed blocks 31 and passing through a positioning notch 21, and a locking nut 6 threadedly connected to the positioning screw 5 to lock the stirring paddle body 3. The fixed discs 2 are provided with positioning notches 21. With the above solution, when the noodle and dough mixer is started, the power system (usually a geared motor) drives the two transmission rods 1 to rotate synchronously through the linkage assembly 4. Under the drive of the transmission rods 1, the two fixed discs 2 fixed on them rotate accordingly, and then through the tight connection between the positioning screw 5 and the locking nut 6, the stirring paddle body 3 is driven to make a spiral trajectory movement.

[0042] The main body 3 of the spiral structure plays a core role in the rotation process: its spiral blades form a specific angle with the material contact surface. When it rotates, on the one hand, it generates an axial pushing force on the raw material, so that the material reciprocates and circulates along the axis of the transmission rod 1 in the mixing chamber, avoiding local accumulation of raw material; on the other hand, the radial stirring action of the spiral blades continuously shears and disperses the agglomerated raw material. Combined with the cross stirring area formed by the synchronous movement of the two transmission rods 1, a multi-dimensional three-dimensional stirring flow field is constructed in the chamber.

[0043] The positioning notch 21 on the fixed plate 2 and the positioning screws 5 of the fixing blocks 31 at both ends of the impeller body 3 form a precise limiting structure, ensuring that the impeller body 3 maintains stable axial positioning when rotating at high speed, and avoiding deviation of the stirring trajectory due to loosening. The threaded fastening design of the locking nut 6 ensures that the impeller body 3 can be disassembled and maintained, while eliminating the fit gap between the fixed plate 2 and the impeller body 3 through pre-tightening force, so that the stirring load is evenly transmitted to the transmission rod 1, and improving the fatigue resistance of the overall structure.

[0044] When the raw materials enter the mixing chamber, they first form convective mixing under the rotation of the double helical mixing paddle body 3. The rigid connection between the positioning screw 5 and the fixed plate 2 ensures that the paddle maintains a stable working angle when shearing high-viscosity dough. The continuous rotation of the helical blades constantly breaks down the intermolecular forces inside the dough, gradually breaking large clumps into uniform particles. At the same time, the spaced distribution of the two transmission rods 1 forms a mixing blind zone compensation, so that the raw materials near the side wall of the chamber can also be continuously turned over by the scraping action of the edge of the helical blades, ultimately achieving no dead angle anti-clumping mixing throughout the entire chamber.

[0045] The mixing paddle body 3 is detachably installed between two fixed plates 2 and fixed by positioning screws 5 and locking nuts 6. This ensures the stability of the mixing paddle body 3 while also facilitating its disassembly for maintenance, replacement of parts, or cleaning of adhering flour.

[0046] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown in the figure, in this embodiment, the positioning notches 21 of the two fixed disks 2 are distributed at a 180° angle. After adopting the above scheme, specifically, from the perspective of the attached figure, the upper positioning notch 21 is located on the left side, while the lower positioning notch 21 is located on the right side. This design has the following effects:

[0047] The positioning notches 21 are symmetrically distributed at a 180° angle on the two fixed disks 2, so that when the fixed blocks 31 at both ends of the mixing paddle body 3 are inserted into the notches by the positioning screws 5, a strictly centrally symmetrical positioning structure is formed. This design eliminates the radial eccentric force that may be generated by traditional single-sided positioning, and ensures that the axis of the mixing paddle body 3 is completely coaxial with the transmission rod 1 when rotating at high speed. This avoids problems such as paddle vibration or uneven material mixing caused by installation deviation. Even when facing the resistance load of high-viscosity dough, the symmetrical positioning structure can also uniformly decompose the shear force to the two fixed disks 2 through bidirectional limiting action, thereby reducing the bending moment load borne by the transmission rod 1.

[0048] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the width of the positioning notch 21 is matched with the diameter of the positioning screw 5. After adopting the above solution, when in use, after the positioning screw 5 passes through the positioning notch 21, the outer wall of the positioning screw 5 fits the inner wall of the positioning notch 21 to form a precise positioning structure, which greatly improves the stability of the installation of the stirring paddle body 3 and avoids radial vibration when it rotates at high speed.

[0049] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the linkage component 4 includes: a mounting plate 41, a rotating shaft 42 rotatably connected to the mounting plate 41 by bearings, a driving gear 43 fixed to the rotating shaft 42, and two driven gears 44 respectively fixed on two transmission rods 1 and meshing with the driving gear 43. The transmission rods 1 pass through the mounting plate 41. With the above scheme, when the power source drives the rotating shaft 42 to rotate, the driving gear 43 fixed on the rotating shaft 42 rotates synchronously. The rotational motion is transmitted to the two driven gears 44 through the gear meshing pair. Since the driving gear 43 meshes with the driven gears 44 on both sides at the same time, and the driven gears 44 are respectively fixed on the two transmission rods 1, a synchronous transmission structure of "one driving two" is formed.

[0050] The driven gears 44 on both sides drive the corresponding transmission rods 1 to rotate, and the transmission rods 1 drive the stirring paddle body 3 fixed on them to rotate.

[0051] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the fixed disk 2 and the transmission rod 1 are detachably connected. With the above solution, it is convenient to disassemble, repair or replace the damaged fixed disk 2 during use.

[0052] In addition, for different mixing scenarios, different fixing plates 2 can be disassembled and replaced according to the specifications and models of the mixing paddle body 3.

[0053] Optionally, by Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment, it further includes: a fixing flange 8 fixed to the transmission rod 1, and a fixing plate 2 connected to the fixing flange 8 by bolts. With the above solution, the fixing plate 2 is fixedly installed by the fixing flange 8 and bolts during use. While ensuring the stability of the installation of the fixing plate 2, it is also convenient to disassemble it, which facilitates the disassembly, repair or replacement of the damaged fixing plate 2, and also makes it convenient to disassemble and replace different fixing plates 2 according to the specifications and models of the mixing paddle body 3.

[0054] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, it further includes: a positioning pin 7 fixed to the outer wall of the transmission rod 1, and a pin hole 22 for the positioning pin 7 to pass through. With the above solution, in use, the positioning pin 7 and the pin hole 22 are used to position the installation position and installation direction of the fixed plate 2, so as to ensure the accuracy of the installation position of the stirring paddle body 3.

[0055] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the positioning pin 7 and the pin hole 22 are interference-fitted. After adopting the above solution, this tight fit provides a stable mechanical constraint on the fixed plate 2 during use, which greatly improves the stability of the fixed plate 2 installation and effectively avoids the fixed plate 2 from slipping when the transmission rod 1 rotates at a high speed, ensuring that the fixed plate 2 and the transmission rod 1 always rotate at the same speed and in the same direction.

[0056] Components not described in detail in this article are existing technologies.

[0057] The working principle and usage process of this utility model: When the noodle and dough machine is started, the power system drives the two transmission rods 1 to rotate synchronously through the linkage component 4. Under the drive of the transmission rods 1, the two fixed disks 2 fixed on them rotate accordingly. Then, through the fastening connection between the positioning screw 5 and the locking nut 6, the stirring paddle body 3 is driven to make a spiral trajectory movement.

[0058] The main body of the spiral-structured stirring paddle 3 plays a core role during rotation: its spiral blades form a specific angle with the material contact surface. When it rotates, it generates an axial pushing force on the raw material, causing the material to reciprocate and circulate along the axis of the transmission rod 1 in the stirring chamber, thus avoiding local accumulation of raw material.

[0059] On the other hand, the radial stirring action of the spiral blades continuously shears and disperses the agglomerated raw materials, and the cross stirring area formed by the synchronous movement of the double drive rods 1 creates a multi-dimensional stirring flow field in the cavity.

[0060] The positioning notch 21 on the fixed plate 2 and the positioning screws 5 of the fixing blocks 31 at both ends of the impeller body 3 form a precise limiting structure, ensuring that the impeller body 3 maintains stable axial positioning when rotating at high speed, avoiding deviation of the stirring trajectory due to loosening. The threaded fastening design of the locking nut 6 ensures that the impeller body 3 can be disassembled and maintained, while eliminating the fit gap between the fixed plate 2 and the impeller body 3 through pre-tightening force, so that the stirring load is evenly transmitted to the transmission rod 1, improving the fatigue resistance of the overall structure.

[0061] When the raw materials enter the mixing chamber, they first form convective mixing under the rotation of the double helix mixing paddle body 3. The rigid connection between the positioning screw 5 and the fixed plate 2 ensures that the paddle maintains a stable working angle when shearing high-viscosity dough. The continuous rotation of the helical blades constantly destroys the intermolecular forces inside the dough, gradually breaking large clumps into uniform particles. At the same time, the spaced distribution of the two transmission rods 1 forms a mixing blind zone compensation, so that the raw materials near the side wall of the chamber can also be continuously turned over by the edge scraping action of the helical blades, ultimately achieving no dead angle anti-clumping mixing in the entire chamber.

[0062] The mixing paddle body 3 is detachably installed between two fixed plates 2 and fixed by positioning screws 5 and locking nuts 6. This ensures the stability of the mixing paddle body 3 while also facilitating its disassembly for maintenance, replacement of parts, or cleaning of adhering flour.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
