Description

Technical Field

[0001] This application relates to the technical field of food processing machinery, and in particular to a detachable and washable two-stage shearing and grinding assembly for a soymilk maker. Background Technology

[0002] Soy milk makers are mainly used to automatically process soybeans and other legumes through a built-in high-speed motor and grinding components, quickly producing smooth and palatable raw or cooked soy milk that can be consumed directly.

[0003] Existing soymilk makers include a body, a base, and a lid. The body is fixed to the base, which houses a heating element. A motor is fixed to the lid, and a rotating shaft, fixedly connected to the motor's output shaft, is located on its lower surface. A funnel-shaped shell is also fixed to the lower surface of the lid, with a liquid inlet on its side wall and a stationary grinding head fixed to its bottom. The rotating shaft vertically passes through and rotates with the stationary grinding head. A movable grinding head is fitted and fixed on the rotating shaft, positioned above the stationary grinding head with a grinding gap between them. Both the movable and stationary grinding heads have liquid outlets, and a shearing blade is connected to the bottom of the rotating shaft.

[0004] During operation, water and soybeans are first added to the machine body according to the specified ratio. After the motor starts, the rotating shaft drives the moving grinding head and shearing blade to rotate at high speed: the shearing blade cuts the soybeans while simultaneously driving the mixed slurry to rotate at high speed. Under the action of centrifugal force, the slurry climbs upward along the inner wall of the machine body, enters the shell through the inlet, and then flows into the grinding gap between the moving grinding head and the stationary grinding head through the outlet of the moving grinding head, where it is finely ground under the action of relative rotation. The ground slurry flows back into the bottom of the machine body through the outlet of the stationary grinding head, and this cycle is repeated until the pulping process is completed.

[0005] Regarding the aforementioned technologies, since the grinding components such as the moving grinding head, stationary grinding head, and housing are all fixedly installed and difficult to disassemble, the soybean residue left over during the pulping process is easily trapped in the grinding gaps and narrow places such as the liquid outlet. Conventional rinsing is not enough to completely remove it, resulting in the drawback of inconvenient cleaning of soybean milk makers. Summary of the Invention

A bolt is disposed on the shearing blade, and the bolt penetrates the bottom wall of the slide groove and is threadedly connected to the connecting pipe.

[0012] By adopting the above technical solution, the shearing blade is fixed to the connecting pipe by bolts. At the same time, the bolts push the sliding plate upward, so that the inclined surface of the limiting rod abuts against the inclined surface of the fixed plate, thereby limiting the retraction of the fixed rod and realizing the linkage locking between the moving grinding head and the shearing blade.

[0018] By adopting the above technical solution, the inclined structure can automatically push the locking rod back during the installation of the guide shell, and automatically lock in after the locking groove is aligned, achieving the effect of "pushing in and locking", thus improving assembly efficiency.

[0019] Optionally, a conveying pipe is fixedly provided on the side wall of the guide shell, and the conveying pipe is connected to the interior of the guide shell; the conveying assembly includes a rotating rod and a spiral blade, the rotating rod is disposed on one side of the rotating shaft, and the length direction of the rotating rod is parallel to the length direction of the rotating shaft, the end of the rotating rod near the machine cover is rotatably connected to the machine cover, and the end of the rotating rod away from the machine cover extends into the conveying pipe; the spiral blade is fixedly disposed on the circumferential side wall of the rotating rod along the length direction of the rotating rod, and the spiral blade is located inside the conveying pipe; a rotating assembly for driving the rotating rod to rotate is provided at the machine cover.

[0023] Optionally, a protective shell is fixedly provided on the lower surface of the cover, the main gear and the driven gear are both located inside the protective shell, and the rotating rod and the rotating shaft both pass through the protective shell and are rotatably connected to the protective shell.

[0024] By adopting the above technical solution, the protective shell can effectively prevent soybean residue or slurry from entering the gear meshing area, avoid jamming or wear, and improve the service life and reliability of the transmission system.

[0025] Optionally, the bottom end of the conveying pipe is a closed structure, and an inlet is provided on the side wall of the bottom end of the conveying pipe. A filter screen is fixedly installed at the inlet of the conveying pipe.

This solves the problem of inconvenient cleaning of traditional fixed grinding assemblies. At the same time, the installation and disassembly of each component are convenient and do not affect the efficiency of the soy milk maker. 2. The linkage design of the fixed component and the limiting component combines the bolt installation of the shearing blade with the limit locking of the moving grinding head, eliminating the need for additional limiting operations, simplifying the assembly process, and effectively preventing the moving grinding head from loosening due to vibration during the operation of the soymilk maker, ensuring the stability of the grinding work; the setting of the second spring realizes the automatic reset of the sliding plate, which provides convenience for the disassembly of the moving grinding head and makes the overall disassembly and assembly process smoother. 3. The conveying components are synchronized with the rotating shaft through gear meshing, eliminating the need for a separate drive source and simplifying the equipment structure. Compared to the traditional centrifugal upward conveying method, the active conveying method of the spiral blades is more efficient and stable in conveying the slurry, ensuring the continuity of grinding. The filter screen can filter out large particles of soybeans, preventing the conveying components from clogging. The design of the liquid inlet position ensures the thorough circulation of the slurry, all of which together improve the grinding efficiency and the smoothness of the soy milk.

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0030] This application discloses a detachable and washable two-stage shearing and grinding assembly for a soymilk maker.

[0031] refer to Figure 1 The removable and washable dual-stage shearing and grinding assembly of the soymilk maker includes a cover 1. Below the cover 1 is a funnel-shaped guide shell 12, the upper port diameter of which is larger than the lower port diameter. A conveying pipe 7 is fixedly mounted on the side wall of the guide shell 12, and the conveying pipe 7 is vertically arranged.

[0032] refer to Figure 1 and Figure 2 A drive motor 11 is fixed to the upper surface of the cover 1. A rotating shaft 2 is vertically arranged below the cover 1, with its upper end penetrating the cover 1 and fixedly connected to the output shaft of the drive motor 11. A moving grinding head 21 is sleeved on the rotating shaft 2, and a shearing blade 22 is bolted to the bottom end of the rotating shaft 2. A stationary grinding head 13 is welded and fixed to the bottom end of the guide shell 12, with the rotating shaft 2 vertically penetrating the stationary grinding head 13 and rotatably connected to it. The moving grinding head 21 is located above the stationary grinding head 13, with a grinding gap between them. A first through hole 211 is formed through the moving grinding head 21, and a second through hole 131 is formed through the stationary grinding head 13.

[0033] After the drive motor 11 starts, it can drive the rotating shaft 2 to rotate at high speed around its own axis. When the rotating shaft 2 rotates, it will simultaneously drive the moving grinding head 21 and the shearing blade 22 to rotate. The shearing blade 22 first performs preliminary shearing and crushing of the soybeans. Then, the slurry entering the guide shell 12 flows from the first through hole 211 to the gap between the moving grinding head 21 and the stationary grinding head 13. The rotating moving grinding head 21 cooperates with the fixed stationary grinding head 13 to perform secondary fine grinding of the soybeans through the grinding gap between them. After fine grinding, the slurry flows into the machine body from the second through hole 131, forming a double-stage shearing and grinding effect, making the grinding of soybeans more thorough.

[0034] refer to Figure 2 , Figure 3 and Figure 4 The rotating shaft 2 has a sliding groove 23 inside along its own length direction, and a moving groove 24 connected to the sliding groove 23 is provided on the side wall of the rotating shaft 2. A fixing component 3 is provided on the rotating shaft 2 for detachably fixing the moving grinding head 21.

[0035] The fixing assembly 3 includes a fixing rod 31 and a first spring 32. The fixing rod 31 is slidably connected within the moving groove 24. A fixing plate 25 located within the sliding groove 23 is sleeved and fixed on the fixing rod. The first spring 32 is fixed between the fixing plate 25 and one side wall of the sliding groove 23, and the extension and retraction direction of the first spring 32 is parallel to the sliding direction of the fixing rod 31. The inner wall of the moving grinding head 21 has a fixing groove 212 that is adapted to be inserted into the fixing rod 31. One end of the fixing rod 31 facing the outside of the moving groove 24 has a guide slope that slopes from the middle to both sides.

[0036] When the moving grinding head 21 is fitted onto the rotating shaft 2, the inner wall of the moving grinding head 21 will first contact the guide slope of the fixed rod 31. As the moving grinding head 21 continues to move upward, the squeezing force of the inner wall on the guide slope will push the fixed rod 31 back into the moving groove 24 and the sliding groove 23. At the same time, it will drive the fixed plate 25 to squeeze the first spring 32, so that the first spring 32 is in a compressed state until the moving grinding head 21 slides to the position of the fixed groove 212 and the moving groove 24 are aligned. At this time, the rebound force of the first spring 32 will push the fixed plate 25 and the fixed rod 31 to return to their original positions, so that the end of the fixed rod 31 is inserted into the fixed groove 212, completing the initial snap-fit ​​fixation between the moving grinding head 21 and the rotating shaft 2. The entire installation process does not require manual adjustment of the fixed rod 31 and can be completed automatically by relying on the cooperation of the structure, making the operation convenient. After this, the guide shell 12 is fixed, and finally the shearing blade 22 is installed.

[0037] refer to Figure 2 , Figure 3 and Figure 4The slide 23 is also equipped with a limiting component 6 to restrict the retraction of the fixed rod 31 into the moving groove 24. The limiting component 6 includes a slide plate 61 horizontally disposed in the slide 23. The slide plate 61 is slidably connected to the rotating shaft 2 along the length of the slide 23, and the slide plate 61 is located below the fixed rod 31. A limiting rod 62 is welded and fixed to the side of the slide plate 61 facing the fixed rod 31. The length direction of the limiting rod 62 is parallel to the length direction of the rotating shaft 2. The end of the limiting rod 62 away from the slide plate 61 is set as an inclined surface. The lower surface of the fixed plate 25 is provided with an inclined surface adapted to the inclined surface of the limiting rod 62. A connecting pipe 26 is welded and fixed to the bottom wall of the slide 23. The connecting pipe 26 is located below the slide plate 61. The connecting pipe 26 has an internal thread. A bolt 27 is provided on the shearing blade 22. The bolt 27 penetrates the bottom wall of the slide 23 and is threadedly connected to the connecting pipe 26. A second spring 28 is also fixedly installed between the slide plate 61 and the bottom wall of the slide groove 23. The second spring 28 is sleeved on the outside of the connecting pipe 26.

[0038] When the bolt 27 on the shearing blade 22 is tightened, the bolt 27 will screw upward along the internal thread of the connecting pipe 26. The end of the bolt 27 will contact the sliding plate 61 and generate an upward thrust on it, pushing the sliding plate 61 to slide upward along the slide groove 23. The upward movement of the sliding plate 61 will drive the limiting rod 62 to move upward synchronously until the inclined surface of the limiting rod 62 is in contact with the inclined surface of the fixing plate 25. At this time, the limiting rod 62 forms an upward pushing force on the fixing plate 25, preventing the fixing plate 25 from driving the fixing rod 31 to retract into the moving groove 24, thereby achieving the limiting and locking of the fixing rod 31, making the fixing of the moving grinding head 21 more stable, and preventing the fixing rod 31 from retracting and the moving grinding head 21 from loosening due to vibration during the operation of the soy milk maker. When the bolt 27 is loosened, the rebound force of the second spring 28 will push the sliding plate 61 downward to reset, causing the limiting rod 62 to separate from the fixing plate 25, releasing the limiting of the fixing rod 31, and providing conditions for the disassembly of the moving grinding head 21.

[0039] refer to Figure 2 and Figure 5 The upper end of the flow guide shell 12 is welded and fixed to the two outer side walls. The connecting block 14 is provided with a slot 141. The lower surface of the cover 1 is welded and fixed with two fixing blocks 15. The side of the fixing block 15 is provided with a relief groove 151. The relief groove 151 penetrates the side wall of the fixing block 15. The connecting block 14 and the relief groove 151 are plugged and matched and correspond one to one. The fixing block 15 is provided with a snap-fit ​​component 4 that can snap and fix with the connecting block 14.

[0040] The snap-fit ​​assembly 4 includes a snap-fit ​​rod 41 and an auxiliary plate 42. The length direction of the snap-fit ​​rod 41 is parallel to the length direction of the rotating shaft 2. One end of the snap-fit ​​rod 41 passes through one side wall of the clearance groove 151 and extends into the clearance groove 151. The snap-fit ​​rod 41 is slidably connected to the fixing block 15. The end of the snap-fit ​​rod 41 located in the clearance groove 151 is snap-fitted into the snap-fit ​​groove 141. The end of the snap-fit ​​rod 41 away from the auxiliary plate 42 is provided with a bevel. The other end of the snap-fit ​​rod 41 is welded and fixed to the auxiliary plate 42. A third spring 16 is fixedly provided between the auxiliary plate 42 and the fixing block 15. The third spring 16 is sleeved on the outside of the snap-fit ​​rod 41. One end of the third spring 16 is welded to the auxiliary plate 42, and the other end is welded to the fixing block 15.

[0041] When installing the flow guide shell 12, align the connecting block 14 at the upper end of the flow guide shell 12 with the clearance groove 151 of the fixing block 15 and push it inward. The end of the connecting block 14 will contact the inclined surface of the clamping rod 41. The squeezing force pushes the clamping rod 41 to slide away from the clearance groove 151. The sliding of the clamping rod 41 will cause the auxiliary plate 42 to stretch the third spring 16, so that the third spring 16 is in a stretched state. When the connecting block 14 slides to the position where the clamping groove 141 and the clamping rod 41 are aligned, the rebound force of the third spring 16 will pull the auxiliary plate 42 and the clamping rod 41 to reset, so that the end of the clamping rod 41 is inserted into the clamping groove 141, thus completing the clamping and fixing of the flow guide shell 12 and the cover 1. When it is necessary to disassemble the flow guide shell 12, simply pull the auxiliary plate 42 outward to disengage the clamping rod 41 from the clamping groove 141, thereby releasing the clamping and removing the flow guide shell 12 from under the cover 1. The entire disassembly and assembly process does not require any additional tools and is simple and efficient.

[0042] refer to Figure 1 and Figure 2 A conveying assembly 5 is provided at the conveying pipe 7 to convey the soybean milk to be ground at the bottom of the machine body into the guide shell 12. The conveying assembly 5 includes a rotating rod 51 and a spiral blade 52. The length direction of the rotating rod 51 is parallel to the length direction of the rotating shaft 2. The end of the rotating rod 51 near the machine cover 1 is rotatably connected to the machine cover 1, and the end of the rotating rod 51 away from the machine cover 1 extends into the conveying pipe 7. The spiral blade 52 is welded and fixed to the circumferential side wall of the rotating rod 51 along the length direction of the rotating rod 51, and the spiral blade 52 is located inside the conveying pipe 7. A rotating assembly 8 is provided at the machine cover 1 to drive the rotating rod 51 to rotate.

[0043] The rotating assembly 8 includes a main gear 81 fixedly sleeved on the upper end of the rotating shaft 2 and a driven gear 82 fixedly sleeved on the upper end of the rotating rod 51, with the main gear 81 and the driven gear 82 meshing. A protective shell 17 is welded and fixed to the lower surface of the cover 1, with both the main gear 81 and the driven gear 82 located inside the protective shell 17. The rotating rod 51 and the rotating shaft 2 both pass through the protective shell 17 and are rotatably connected to it.

[0044] When the drive motor 11 drives the rotating shaft 2 to rotate, it will synchronously drive the main gear 81 to rotate. The main gear 81 transmits power to the driven gear 82 and the rotating rod 51 through meshing with the driven gear 82, so that the rotating rod 51 rotates synchronously with the rotating shaft 2. The rotation of the rotating rod 51 will drive the spiral blades 52 in the conveying pipe 7 to rotate. When the spiral blades 52 rotate, they will generate spiral lift, which will continuously convey the slurry to be ground at the bottom of the machine body upward, and finally send it into the guide shell 12 to participate in grinding, realizing the active circulation and conveying of the slurry. At the same time, the protective shell 17 encloses the gear transmission structure, which can effectively prevent the slurry from splashing into the gear meshing point during the pulping process, causing component wear or jamming, and ensuring the stability and service life of the gear transmission.

[0045] refer to Figure 1 and Figure 2 The bottom end of the conveying pipe 7 is a closed structure, and an inlet 71 is provided on the side wall of the bottom end of the conveying pipe 7. A filter screen 72 is fixed at the inlet 71 of the conveying pipe 7. The closed structure at the bottom end of the conveying pipe 7 can prevent the slurry from leaking from the bottom end, while the inlet 71 is provided on the side wall of the bottom end, which allows the spiral blades 52 to more fully absorb the slurry at the bottom of the machine body, ensuring the thorough circulation of the slurry and preventing unground soybeans from remaining at the bottom of the machine body. When the slurry enters the conveying pipe 7 through the inlet 71, the filter screen 72 will filter the slurry, blocking large soybean particles that have not been sheared and crushed outside the conveying pipe 7, preventing large soybean particles from entering the conveying pipe 7 and causing the spiral blades 52 to get stuck or the conveying pipe 7 to get blocked, ensuring the normal operation of the conveying component 5. At the same time, it can also make the slurry particles entering the guide shell 12 more uniform, improving the subsequent grinding effect.

[0046] The implementation principle of the detachable and washable dual-stage shearing and grinding assembly for a soymilk maker in this embodiment is as follows: the moving grinding head 21 is detachably installed via the fixing component 3, and the flow guide shell 12 is detachably connected via the snap-fit ​​component 4, allowing the entire grinding assembly to be disassembled and cleaned, preventing soy residue residue. Simultaneously, the conveying component 5 facilitates the circulation and conveying of the soymilk, improving the grinding effect. The linkage locking structure between the fixing component 3 and the shearing blade 22 ensures the stability of the moving grinding head 21 during high-speed rotation; the inclined snap-fit ​​structure of the snap-fit ​​component 4 enables quick disassembly and assembly of the flow guide shell 12. The overall structure is ingeniously designed, easy to disassemble and assemble, and thoroughly cleaned, effectively improving the ease of use and cleaning of the soymilk maker.

[0047] The embodiments described in this specific implementation are 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.
