Description

Technical Field

[0001] This utility model relates to the field of rice hulling machine technology, specifically to a rice hulling machine rubber roller gap adjustment device. Background Technology

[0002] In rice processing, the rice huller is one of the key pieces of equipment, its main function being to remove the husk from paddy rice and convert it into brown rice. The performance of the rice huller directly affects the hulling efficiency and the quality of the brown rice, and the gap between the rubber rollers is a core parameter in the operation of the rice huller. The size of the gap determines the squeezing and friction forces experienced by the paddy rice between the rollers, thus affecting the hulling effect and the integrity of the rice grains.

[0003] An appropriate gap between the rubber rollers ensures effective hulling of the rice while minimizing damage to the grains. If the gap is too large, the rice may not be fully hulled, resulting in a lower hulling rate; if the gap is too small, it may cause excessive compression of the grains, increasing the breakage rate and affecting the quality of the finished rice. Therefore, properly adjusting the gap between the rubber rollers is crucial for ensuring the efficient and stable operation of the rice huller and is an important step in improving the quality of rice processing.

[0004] However, after prolonged operation, the diameter of the rubber rollers in a rice huller gradually decreases due to continuous friction, leading to an increase in the gap between the two rollers. This change in gap makes the squeezing and friction forces exerted by the rollers on the rice unstable, thus affecting the hulling effect and the quality of the rice grains. Currently, the main method to solve this problem is for workers to manually adjust the brackets that fix the rubber rollers to restore the appropriate roller gap. However, this manual adjustment method has significant drawbacks: firstly, each adjustment requires specific adjustments based on the wear level of the rubber rollers, making the operation cumbersome and time-consuming; secondly, the precision of manual adjustment is difficult to guarantee, easily leading to inaccurate adjustments, which in turn affects the stable operation of the rice huller and the quality of rice processing.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0025] To address the technical problems in the background section, the following is provided: a rice huller rubber roller gap adjustment device.

[0026] Combination Figures 1-5 As shown, this utility model provides a rice huller rubber roller gap adjustment device, including a fixed box 1, which is fixed to the side wall of the suction pipe 8 and set on the top of the rice husk separation box 6. A feed hopper 7 is provided inside the fixed box 1, and a short plate 71 is connected to the bottom surface of the feed hopper 7. A movable gap adjustment mechanism 3 is connected between the bottom surface of the fixed box 1 and the top surface of the rice husk separation box 6. A discharge port 13 is opened on the bottom surface of the fixed box 1. The short plate 71 is set on the top of the gap adjustment mechanism 3. A movable rubber roller 2 is rotatably connected inside the gap adjustment mechanism 3, and one end of the movable rubber roller 2 is connected to... There is a first motor 21, which is fixed to the side wall of the gap adjustment mechanism 3. A fixed bracket 5 is fixed on the top surface of the rice husk separation box 6. There are two fixed brackets 5 mirror images of the vertical center line of the rice husk separation box 6. A fixed rubber roller 4 is rotatably connected between the two fixed brackets 5. A third motor 41 is connected to one end of the fixed rubber roller 4. The third motor 41 is fixed to the side wall of one of the fixed brackets 5. The bottom surface of the gap adjustment mechanism 3 is slidably connected to the top surface of the rice husk separation box 6. The movable rubber roller 2 is translated through the gap adjustment mechanism 3 to adjust the gap between the movable rubber roller 2 and the fixed rubber roller 4.

[0027] The above structure achieves the following effect:

[0028] By setting the movable rubber roller 2 inside the gap adjustment mechanism 3, and fixing the fixed rubber roller 4 on the top surface of the rice husk separation box 6, the gap between the movable rubber roller 2 and the fixed rubber roller 4 can be adjusted in a timely manner by moving the gap adjustment mechanism 3 horizontally on the top surface of the fixed box 1 and the rice husk separation box 6 when the gap between the fixed rubber roller 4 and the movable rubber roller 2 changes, thus improving the stability and convenience of the adjustment operation.

[0029] In this embodiment, the gap adjustment mechanism 3 includes a main push assembly 31, a side support assembly 32, a sliding guide plate 33, and a second limiting plate 34. The main push assembly 31 is disposed on the bottom surface of the fixed box 1. A side support assembly 32 is connected to one side of the main push assembly 31. Two sets of side support assemblies 32 are mirror images of the vertical centerline of the main push assembly 31. The movable rubber roller 2 is rotatably connected between the two sets of side support assemblies 32. The sliding guide plate 33 is slidably attached to the top surface of the rice husk separation box 6. The second limiting plate 34 has an inverted L-shaped structure. The second limiting plate 34 is fixed to the top surface of the rice husk separation box 6. Two second limiting plates 34 are mirror images of the vertical centerline of the rice husk separation box 6. The sliding guide plate 33 is slidably inserted between the two second limiting plates 34. The bottom end of the side support assembly 32 is connected to the inside of the sliding guide plate 33.

[0030] The main push assembly 31 on the bottom surface of the fixed box 1 pushes the two sets of side support assemblies 32 to move horizontally, thereby causing the movable rubber roller 2 to move horizontally to adjust the gap. At the same time, the two sets of side support assemblies 32 are connected to the sliding guide plate 33. The sliding guide plate 33 guides the horizontal movement inside the two second limit plates 34, further realizing the guiding and horizontal movement of the movable roller, and further ensuring the guidance and stability of the gap adjustment.

[0031] In this embodiment, the main push assembly 31 includes a second motor 311, a screw 312, a push plate 313, and a fixing block 314. The second motor 311 is fixed to the bottom surface of the fixing box 1. The rotating end of the second motor 311 is connected to the screw 312. The fixing block 314 is fixed to the bottom surface of the fixing box 1. One end of the screw 312 is rotatably connected to the inside of the fixing block 314. The outer wall of the screw 312 is threaded with the push plate 313. The push plate 313 slides against the bottom surface of the fixing box 1. Two sets of side support assemblies 32 are respectively fixed to the two side walls of the push plate 313.

[0032] By driving the screw 312 to rotate, the push plate 313 can be moved horizontally, allowing for adjustment of the push plate 313 over a small distance, resulting in precise and stable adjustment operations.

[0033] In this embodiment, the side support assembly 32 includes a sleeve 321, a second toothed plate 325, a movable bracket 326, and a guide plate 327. The sleeve 321 is fixed to the side wall of the push plate 313. The second toothed plate 325 is inserted into the sleeve 321. The bottom surface of the second toothed plate 325 is connected to the movable bracket 326. The movable rubber roller 2 is rotatably connected inside the movable bracket 326. The bottom surface of the movable bracket 326 is connected to the guide plate 327, which is inserted into the sliding guide plate 33.

[0034] In this embodiment, the side support assembly 32 further includes a first rotating shaft 322, a first gear 323, and a second gear 324. The first rotating shaft 322 is rotatably connected to the side wall of the sleeve 321. The first gear 323 and the second gear 324 are sleeved on the outer wall of the first rotating shaft 322. A first toothed plate 11 is fixed on the bottom surface of the fixed box 1. The top of the first gear 323 is meshed with the bottom surface of the first toothed plate 11. One side of the second gear 324 is connected through the inside of the sleeve 321. One side of the second gear 324 is meshed with the second toothed plate 325. The second toothed plate 325 is slidably inserted into the inside of the sleeve 321. The guide plate 327 is slidably inserted through the inside of the sliding guide plate 33.

[0035] When the push plate 313 is pushed to make the two sets of side support components 32 move the movable rubber roller 2 horizontally, the first gear 323 meshes with the first toothed plate 11 to drive the second gear 324 to rotate and drive the second toothed plate 325 to rise and fall. Thus, while adjusting the gap by horizontal movement, the gap can also be adjusted by rising and falling, thereby achieving oblique adjustment. This ensures that the adjustment is made in the direction of the axis connecting the movable rubber roller 2 and the fixed rubber roller 4, further improving the stability and accuracy of the gap adjustment. Example 2

[0036] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0037] The gap adjustment mechanism 3 also includes a flat tilting component 35 and a long plate 36. The flat tilting component 35 is connected to the top surface of the push plate 313 and is connected through the inside of the fixed box 1. The top of one side of the flat tilting component 35 is set at the bottom of the short plate 71, and the bottom of one side of the flat tilting component 35 is connected to the long plate 36. The bottom of the long plate 36 is set at the top of the gap between the movable rubber roller 2 and the fixed rubber roller 4.

[0038] By setting the flat-flipping component 35 at the bottom of the short plate 71 and the top of the gap between the two rubber rollers, the material is guided to ensure that the material stably enters the gap between the movable rubber roller 2 and the fixed rubber roller 4.

[0039] In this embodiment, the flat-flipping assembly 35 includes a slider 351, a connecting plate 352, a third toothed plate 353, a rotating rod 354, a third gear 355, and a second rotating shaft 356. The slider 351 is fixed to the top surface of the push plate 313. A sliding interface 12 is provided on the bottom surface of the fixed box 1. The slider 351 is slidably connected to the inside of the sliding interface 12. A connecting plate 352 is fixed to the top surface of the slider 351. A third toothed plate 353 is fixed to both sides of the connecting plate 352. A first limiting plate 14 is fixed inside the fixed box 1. Two first limiting plates 14 are mirror images of the vertical center line of the fixed box 1. A second rotating shaft 356 is fixed to both ends of the rotating rod 354. The second rotating shaft 356 is rotatably connected to the inside of the first limiting plate 14. A third gear 355 is sleeved on the outer wall of the second rotating shaft 356. The bottom of the third gear 355 is meshed with the top surface of the third toothed plate 353. A long plate 36 is fixed to the outer wall of the rotating rod 354.

[0040] When the push plate 313 moves the slider 351, the third toothed plate 353 translates and drives the third gear 355 to rotate, which in turn drives the rotating rod 354 to rotate and cause the long plate 36 to flip. This ensures that the bottom of the long plate 36 is always at the top of the gap between the movable rubber roller 2 and the fixed rubber roller 4, thus ensuring the accuracy of the feeding position after the gap is adjusted.

[0041] Working principle and usage process of this utility model:

[0042] First press Figures 1-5 The rice and other materials are fed into the hopper 7 and fall into the gap between the movable rubber roller 2 and the fixed rubber roller 4 through the short plate 71 and the long plate 36 in sequence. The first motor 21 and the second motor 311 drive the movable rubber roller 2 and the fixed rubber roller 4 to rotate, rolling the rice. The rolled rice then passes through the rice husk separation box 6 and the suction pipe 8 for further separation.

[0043] After a period of use, the gap between the fixed rubber roller 4 and the movable rubber roller 2 increases. To ensure the stability of the rice rolling and separation, the second motor 311 is started to drive the screw 312 to rotate. The screw 312 drives the push plate 313 to move horizontally, and at the same time drives the two sets of side support components 32 to move horizontally, moving the movable rubber roller 2 towards the fixed rubber roller 4, thereby adjusting the gap in the horizontal direction. While the sleeve 321 moves, the first gear 323 meshes with the first toothed plate 11 and rotates, causing the first rotating shaft 322 to drive the second gear 324 to rotate. The second gear 324 meshes with and drives the second toothed plate 325 to descend, moving the movable rubber roller 2 downward. This achieves the adjustment of the gap by moving the movable rubber roller 2 towards the fixed roller 4 in the inclined direction. The adjustment operation is efficient and precise.

[0044] During gap adjustment, the push plate 313 drives the slider 351 to move horizontally inside the sliding interface 12, the connecting plate 352 drives the third toothed plate 353 to move horizontally, the third toothed plate 353 drives the third gear 355 to rotate, so that the rotating rod 354 drives the long plate 36 to flip, keeping the bottom of the flipped long plate 36 in the middle position of the gap between the movable rubber roller 2 and the fixed rubber roller 4, thereby ensuring the accuracy of the feeding position and the stability of the rolling rice separation.
