[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a filling polishing roller according to an embodiment of the present invention. Figure 2 This is an exploded view of a filling polishing roller according to an embodiment of the present invention. The present invention provides a filling polishing roller, including a main shaft assembly 1, a polishing assembly 2, and a cylindrical filling assembly 3. The main shaft assembly 1 includes a main shaft 11, which forms a ventilation and water spray channel, and a first channel 11a connected to the ventilation and water spray channel is provided on its peripheral wall. The polishing assembly 2 is sleeved on the main shaft 11, and a cavity is formed between the polishing assembly 2 and the peripheral wall of the main shaft 11. The polishing assembly 2 has a second channel 2a opened relative to the first channel 11a. The filling assembly 3 is sleeved on the main shaft 11 and disposed in the cavity. The filling assembly 3 has a third channel 3a connecting the first channel 11a and the second channel 2a.

[0034] Specifically, when the filled polishing roller polishes the rice, it drives the main shaft 11 to rotate. The main shaft 11 drives the filling component 3 and the polishing component 2 to rotate, and a moist airflow is introduced into the main shaft 11. The moist airflow passes through the ventilation spray channel, the first channel 11a, the third channel 3a and the second channel 2a in sequence, and is sprayed out from the second channel 2a. Since a cylindrical filling component 3 is provided between the polishing component 2 and the main shaft 11, it can fill the cavity between the polishing component 2 and the main shaft 11, preventing the rice from entering the cavity and remaining in the cavity to deteriorate. By setting the filling component 3 to be cylindrical, the cylindrical filling component 3 is easy to insert into the cavity, and only a single filling component 3 needs to be fixed and positioned.

[0035] It should be understood that, in order to limit the rotation of the filling component 3 relative to the polishing component 2, and to avoid misalignment of the third channel 3a of the filling component 3 with the first channel 11a and the second channel 2a, therefore, as follows: Figure 1 and Figure 2 As shown, in one embodiment, the spindle assembly 1 further includes a first limiting structure 12, which is connected to the spindle 11 and to the polishing assembly 2 and the filling assembly 3, and is used to limit the rotation of the polishing assembly 2 and the filling assembly 3 relative to the spindle 11.

[0036] In this embodiment, by setting a first limiting structure 12, the first limiting structure 12 can restrict the polishing component 2 and the filling component 3 from rotating relative to the main shaft 11, thereby preventing the filling component 3 from rotating relative to the main shaft 11 and the polishing component 2.

[0037] It should be understood that the first limiting structure 12 can be a limiting pin, a limiting screw, or a limiting bolt 217 arranged radially along the main shaft 11.

[0038] In order to limit the two ends of the filling component 3, for this purpose, as follows: Figure 1 and Figure 2 As shown, in one embodiment, the spindle assembly 1 further includes a second limiting structure 13 and a third limiting structure 14, which are respectively disposed at both ends of the polishing assembly 2 to restrict the polishing assembly 2 and the filling assembly 3 from sliding along the axial direction of the spindle 11.

[0039] By setting the second limiting structure 13 and the third limiting structure 14, the axial positions of the polishing component 2 and the filling component 3 along the main shaft 11 can be limited.

[0040] It should be understood that the second limiting structure 13 and the third limiting structure 14 can be a limiting ring, a limiting protrusion, a limiting pin, a limiting screw, or a limiting screw, etc.

[0041] In order to polish the rice using polishing component 2, specifically, as follows: Figure 3 As shown, in one embodiment, the polishing assembly 2 includes a sleeve 21 and a polishing component 22. The sleeve 21 is sleeved on the spindle 11 and forms a cavity between it and the peripheral wall of the spindle 11. The polishing component 22 is disposed on the peripheral wall of the sleeve 21.

[0042] The polishing part 22 is fixed to the main shaft 11 via the sleeve 21, and the polishing part 22 polishes the rice. It should be understood that the polishing part 22 can be a polishing ridge, a polishing scraper, etc.

[0043] In order to move the rice relative to the main axis 11, for this purpose, such as Figure 2 and Figure 3 As shown, in one embodiment, one end of the polishing element 22 is spiral-shaped and the other end is straight-shaped, with the other end of the polishing element 22 arranged along the axial direction of the main shaft 11.

[0044] In this embodiment, when the rice enters the spiral end of the polishing member 22, the polishing member 22 polishes the rice while simultaneously pushing the rice to move axially relative to the main shaft 11. By setting the other end of the polishing member 22 to be straight, the straight polishing member 22 can prolong the contact time with the rice and improve the surface consistency of the polished rice.

[0045] In order to propel the rice along the axial direction of the main shaft 11, for this purpose, as follows: Figure 1 and Figure 2 As shown, in one embodiment, the filler polishing roller further includes a helical propeller 4, which is sleeved on the main shaft 11.

[0046] By setting up a screw propeller 4, which has a spiral-shaped pushing screw, the rice can be pushed to move along the axial direction of the main shaft 11.

[0047] During use, it was found that the polishing component 22, near the rice feed end, experienced the fastest abrasion. This component 22 was the first to wear out and fail, causing premature failure of the polishing roller. Therefore, as... Figure 2 As shown, in one embodiment, the polishing assembly 2 further includes a reinforcing rib 23, which connects the polishing part 22 and the sleeve part 21, and is disposed at one end of the polishing part 22 near the screw propeller 4.

[0048] By setting reinforcing ribs 23, the end of the polishing part 22 closest to the rice feed can be reinforced, which can extend the life of one end of the polishing part 22, and thus extend the life of the entire polishing roller.

[0049] If the sleeve 21 and the polished part 22 are a single piece, their lengths are relatively long, increasing the difficulty of machining. Therefore, as follows: Figure 2 and Figure 3 As shown, in one embodiment, the sleeve component 21 includes a first sleeve 211 and a second sleeve 212, both of which are sleeved on the main shaft 11; the polishing component 22 includes a plurality of first polishing ridges 221 and a plurality of second polishing ridges 222, which are respectively disposed on the first sleeve 211 and the second sleeve 212.

[0050] In this embodiment, the sleeve 21 is split into a first sleeve 211 and a second sleeve 212, and the polishing part 22 is split into a first polishing ridge 221 and a second polishing ridge 222. These parts are processed separately and then spliced ​​together, which avoids the difficulty of processing due to excessive length. Moreover, if the sleeve 21 and the polishing part 22 are partially damaged, only a single section of the sleeve needs to be replaced, saving costs.

[0051] The first polishing rib 221 is spiral-shaped, the second polishing rib 222 is spiral-shaped at one end near the first polishing rib 221 and straight at the other end, and the other end of the second polishing rib 222 is arranged along the axial direction of the main shaft 11.

[0052] In order to form a cavity, for this purpose, such as Figure 3 and Figure 4As shown, in one embodiment, the sleeve 21 further includes a first end ring 213, a second end ring 214, a third end ring 215, and a fourth end ring 216. The first end ring 213 and the second end ring 214 are respectively disposed at both ends of the first sleeve 211 and sleeved on the main shaft 11. The first sleeve 211, the first end ring 213, and the second end ring 214 are combined with the main shaft 11 to form a first cavity. The third end ring 215 and the fourth end ring 216 are respectively disposed at both ends of the second sleeve 212 and sleeved on the main shaft 11. The second sleeve 212, the third end ring 215, and the fourth end ring 216 are combined with the main shaft 11 to form a second cavity. The filling assembly 3 includes a first filling cylinder 31 and a second filling cylinder 32. The first filling cylinder 31 is built into the first cavity, and the second filling cylinder 32 is built into the second cavity.

[0053] By setting the first end ring 213, the second end ring 214, the third end ring 215, and the fourth end ring 216, a first cavity and a second cavity can be formed by respectively surrounding the first sleeve 211, the second sleeve 212, and the main shaft 11. By placing the first filling cylinder 31 inside the first cavity, the axial direction of the first filling cylinder 31 can be limited. By placing the second filling cylinder 32 inside the second cavity, the second filling cylinder 32 can be limited.

[0054] In order to circumferentially position the first sleeve 211, the second sleeve 212, the first filling cylinder 31, and the second filling cylinder 32, for this purpose, as follows: Figure 2 As shown, in one embodiment, the main shaft 11 has a first keyway (not shown in the figure), the screw propeller 4 has a second keyway (not shown in the figure) relative to the first keyway, the first end ring 213 and the first filling cylinder 31 have a third keyway (not shown in the figure) relative to the first keyway, and the first limiting structure 12 is a limiting key. The first limiting structure 12 is disposed in the first keyway, the second keyway and the third keyway to restrict the screw propeller 4, the first filling cylinder 31 and the first sleeve 211 from rotating relative to the main shaft 11.

[0055] By setting keyways and limit keys, the rotation of the screw propeller 4, the first filling cylinder 31, and the first sleeve 211 relative to the main shaft 11 is restricted.

[0056] It should be understood that, in order to enable the first filling cylinder 31 to be slidably installed into the first sleeve 211, in one embodiment, the first end ring 213 and the first sleeve 211 are detachably connected, and the detachable connection can be a spiral, screw, or snap-fit ​​connection, etc.

[0057] When the first filling cylinder 31 needs to be installed, the first end ring 213 is removed, and then the first filling cylinder 31 is inserted into the first sleeve 211 from the first end ring 213. After installation, the first end ring 213 is connected to the first sleeve 211.

[0058] It should be understood that, in order to limit the circumferential movement of the first filling cylinder 31 and the first sleeve 211, therefore, as Figure 2 and Figure 3 As shown, in one embodiment, the sleeve 21 further includes a limiting bolt 217, the threaded end of which passes through the second end ring 214 and connects to the first filling cylinder 31.

[0059] By setting a limiting screw, the first filler can be circumferentially limited from the second end ring 214.

[0060] It should be understood that, in order to limit the axial movement of the screw propeller 4, the polishing assembly 2, and the filling assembly 3, for this purpose, such as Figure 1 and Figure 2 As shown, in one embodiment, the second limiting structure 13 is a fixing ring disposed at one end of the screw propeller 4 away from the polishing assembly 2. The second limiting structure 13 is fixedly connected to the main shaft 11. The third limiting structure 14 is disposed on the second sleeve 212 away from the limiting nut. The limiting nut is sleeved on the main shaft 11 and connected to the main shaft 11. The axial direction of the screw propeller 4, the polishing assembly 2 and the filling assembly 3 is limited by the second limiting structure 13 and the third limiting structure 14.

[0061] The limit nut and the main shaft 11 can be connected by threads, or they can be fixed by fitting together. Alternatively, the limit nut can be fixed by connecting the main shaft 11 with a screw passing through it.

[0062] To facilitate the installation of the second filling cylinder 32 into the second cavity, in one embodiment, the third end ring 215 is detachably connected to the second sleeve 212, and the third end ring 215 and the second sleeve 212 can be connected by screws, bolts and clips.

[0063] When the second filling cylinder 32 needs to be installed, remove the third end ring 215, insert the second filling cylinder 32 into the second sleeve 212 from the third end ring 215, and then connect the third end ring 215 to the second sleeve 212.

[0064] In order to position the second filling cylinder 32 and the second sleeve 212 circumferentially relative to the main shaft 11, in one embodiment, the third end ring 215 has a blind hole at the head of the limiting bolt 217 and is fitted onto the head of the limiting bolt 217 through the blind hole; the main shaft assembly 1 also includes a fixing screw (not shown in the figure), which passes through the third limiting structure 14 and is connected to the fourth end ring 216, so as to realize the positioning and fixing of the third limiting structure 14, the second filling cylinder 32 and the second sleeve 212 relative to the main shaft 11 circumferentially.

[0065] It should be understood that the first channel 11a, the second channel 2a, and the third channel 3a can be slots, holes, etc. Specifically, for example... Figure 2 and Figure 3 As shown, in one embodiment, there are multiple first channels 11a, which are distributed circumferentially along the main shaft 11. Each first channel 11a includes multiple spaced first through holes 11a1, which are distributed axially along the main shaft 11. The third channel 3a is a through groove, which extends along the arrangement direction of the multiple first through holes 11a1 and corresponds to the multiple first through holes 11a1. The second channel 2a is a through groove, and the third channel 3a is arranged relative to the third channel 3a and matches the size of the third channel 3a.

[0066] Specifically, in this embodiment, by setting multiple first through holes 11a1, fluid can be sprayed from various parts of the main shaft 11 in the axial and circumferential directions, which can ventilate and humidify the rice during polishing; by setting a third channel 3a, which covers multiple first through holes 11a1, multi-pore retention is achieved, reducing the number of stuck holes; by setting the size of the second channel 2a to match the size of the third channel 3a, the smooth flow of fluid can be ensured.

[0067] It should be understood that the first sleeve 211 and the second sleeve 212 are both provided with a second channel 2a, and the first filling cylinder 31 and the second filling cylinder 32 are both provided with a third channel 3a.

[0068] This utility model also relates to a rice polishing machine, including the aforementioned filled polishing roller.
