Description

Technical Field

[0001] This invention relates to the fields of mechanical automation technology and food processing equipment technology, specifically a sushi rice spreading device. Background Technology

[0002] Sushi, a traditional Japanese delicacy, has rapidly gained popularity worldwide in recent years. Its preparation process requires extremely high standards for the evenness of rice spreading, thickness control, and hygiene. Traditional manual rice spreading relies on the chef's experience, which has problems such as low efficiency, high labor costs, and insufficient standardization. Against this backdrop, sushi rice spreading machines have emerged to replace manual operation through mechanical automation. Rice spreading equipment generally consists of a hopper, a mixing mechanism, a leveling mechanism, a cutting mechanism, and a conveying mechanism. However, traditional rice spreading equipment is large in size and the hopper is located at the top of the equipment. Workers need to use ladders or other tools to climb up to add rice, which poses safety risks such as slipping and falling. In addition, frequent climbing to add rice is physically demanding for workers. Prolonged high-intensity operation can easily cause workers to feel fatigued and reduce work efficiency. Moreover, as working time increases, fatigue accumulation may lead to operational errors. For example, during the process of climbing to add rice, due to limited operating space, poor visibility, and difficulty in accurately controlling body balance, workers are prone to spilling rice when pouring it into the hopper. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technical solutions, the present invention provides a sushi rice spreading device, which can effectively solve the technical problems mentioned in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a sushi rice spreading device, including a machine frame, on which a hopper, a stirring mechanism, a leveling mechanism, a cutting mechanism, a conveying mechanism, a lifting and turning mechanism and a material conveying mechanism are sequentially assembled; The hopper is used to receive materials, including rice for making sushi. The lifting and tilting mechanism is connected to the hopper and is used to drive the hopper to rise and fall vertically. After the hopper is lifted to a preset height, it tilts and tilts, causing the material in the hopper to pour onto the material conveying mechanism. The material conveying mechanism includes a conveying frame and a first conveying component assembled inside the conveying frame, and a first discharge chute for material discharge is provided at one end of the conveying frame; The mixing mechanism includes a mixing drive unit, a first mixing component, a mixing frame, a second mixing component, a second conveying component storage hopper, and a drive assembly. The first mixing component is mounted above the first material discharge trough. The mixing drive unit is used to drive the first mixing component to mix and disperse the material. The drive assembly is connected to the second conveying component and the second mixing component and is used to drive the second conveying component to operate to convey the material, and at the same time drive the second mixing component to mix and disperse the material. The leveling mechanism includes an upper pressure roller assembly, a lower pressure roller assembly, a first drive module, a second drive module, and a thickness adjustment assembly. The upper pressure roller assembly includes a first upper pressure roller and a second upper pressure roller, and the lower pressure roller assembly includes a first lower pressure roller and a second lower pressure roller. The material falls between the first upper pressure roller and the second upper pressure roller and is output between the first lower pressure roller and the second lower pressure roller. The thickness adjustment assembly is configured to adjust the distance between the first upper pressure roller and the second upper pressure roller, as well as between the first lower pressure roller and the second lower pressure roller. The conveying mechanism is used to convey the leveled material; The cutting mechanism is located above the conveying mechanism and cuts the material to a preset length during the material conveying process.

[0005] Furthermore, the lifting and tilting mechanism includes a track plate, a movable frame, a transmission assembly, and a driver. The track plate is provided with a lifting and tilting track. The transmission assembly is connected to the movable frame, and the driver is connected to the transmission assembly. The driver drives the transmission assembly to move the movable frame along the lifting and tilting track. The movable frame includes a lifting bracket, a connecting member, and a tilting bracket. The tilting bracket can rotate relative to the lifting bracket towards the material conveying mechanism with the connecting member as the rotation center, so as to pour the material in the hopper onto the material conveying mechanism. The lifting bracket is equipped with a first angle limiting block and a second angle limiting block at one end near the tilting bracket. The second angle limiting block is configured to limit the rotation angle range of the tilting bracket during the deflection process. The first angle limiting block limits the rotation angle range of the movable frame when the driver drives the movable frame to reset through the transmission component, and makes the hopper parallel to the horizontal plane.

[0006] Furthermore, the conveyor frame is composed of multiple quick-assembly plates with a quick-assembly structure. The quick-assembly structure consists of splicing protrusions and splicing grooves on the opposite surfaces of adjacent quick-assembly plates. The splicing protrusions can be quickly embedded into the splicing grooves to achieve the splicing of adjacent quick-assembly plates. The conveyor frame is also equipped with a first transmission rod, a locking component, and multiple connecting rods. At least two connecting rods are provided with snap-fit ​​grooves, and the locking component is provided with snap-fit ​​holes. The diameter of the snap-fit ​​holes is smaller at the top and larger at the bottom. The locking component is assembled on the outside of the conveyor frame, and the connecting rods can pass through the snap-fit ​​holes. The first transmission module is detachably assembled on the conveyor frame. The first transmission module includes a first driving roller, a first driven roller, and two frames. The first driven roller is connected to one of the frames. During assembly, the first driving roller is sleeved on the first transmission rod of the conveyor frame, and the frame is sleeved on the connecting rod of the conveyor frame through the perforations thereon, so that the first driven roller is assembled on the side away from the first driving roller. The first conveyor belt is sleeved on the outside of the first driving roller and the first driven roller of the first transmission module. The locking member is pressed down so that the locking groove of the connecting rod is locked at the upper end of the locking hole of the locking member, so that the conveyor frame is connected to the first transmission module.

[0007] Furthermore, the first stirring assembly is detachably mounted on the conveyor frame; The first stirring assembly includes a first stirring rod, a first transmission unit, and a stirring drive unit. A second transmission rod for driving the first stirring rod to rotate is also provided on the conveyor frame. The output end of the first transmission unit is connected to the first stirring rod, and the stirring drive unit is connected to the input end of the first transmission unit. The stirring drive unit drives the first stirring rod to rotate by driving the first transmission unit, so as to disperse and stir the material.

[0008] Furthermore, the stirring rack is detachably mounted on the machine frame, and the second stirring assembly is mounted inside the stirring rack. The second stirring assembly includes a second stirring rod and at least two third stirring rods, and the surface of the third stirring rods is uniformly provided with a plurality of columnar stirring sections. An opening is provided at the bottom of the mixing rack, and the second conveying component is located at the bottom of the mixing rack; The second conveying assembly includes a second conveyor belt and a second transmission module. The length of the second conveyor belt is less than the length of the mixing frame, so that a second material drop trough is formed at the bottom of the mixing frame in the area not covered by the second conveyor belt. The storage hopper is located directly below the second discharge chute to receive the material falling from the second discharge chute.

[0009] Furthermore, a first driven gear set and a second driven gear set are mounted on the side of the mixing rack. The drive assembly includes a drive motor, a transmission gear set, and a transmission shaft mounted on the frame. The transmission gear set is linked with the first driven gear set and the second driven gear set respectively through the transmission shaft. The second stirring rod is connected to the second driven gear set, and the third stirring rod is connected to the first driven gear set. The drive motor drives the transmission gear set to rotate, and the transmission shaft transmits power synchronously to the first and second driven gear sets to drive the second and third stirring rods to rotate synchronously to disperse and stir the material. The second transmission module includes a second driving roller and a second driven roller. The second driving roller and the second driven roller are rotatably connected to the machine frame. The second driving roller is connected to the first driven gear set, so that the second conveying component and the second stirring component operate synchronously, realizing the simultaneous conveying of materials and the dispersing and stirring of the materials. The first conveying component is parallel to the length direction of the machine frame, and the second conveying component is parallel to the width direction of the machine frame. When the rice is conveyed along the first conveying component, the first stirring component stirs and disperses the rice in a first direction.

[0010] Furthermore, an opening is provided at the bottom of the storage hopper to form a third discharge chute, and a leveling mechanism is provided directly below the third discharge chute to receive the material falling from the third discharge chute. The upper pressure roller assembly and the lower pressure roller assembly are detachably mounted on the machine frame. The upper pressure roller assembly includes a first upper pressure roller and a second upper pressure roller, and the lower pressure roller assembly includes a first lower pressure roller and a second lower pressure roller. The first drive module is used to drive the first upper pressure roller and the second upper pressure roller to rotate in opposite directions, and the second drive module is used to drive the first lower pressure roller and the second lower pressure roller to rotate in opposite directions. The fuselage frame is equipped with two symmetrically distributed mounting brackets that are fixed relative to the fuselage frame. The fuselage frame is also equipped with two symmetrically distributed swing arm brackets that can rotate relative to the fuselage frame. The first upper pressure roller and the first lower pressure roller are mounted on two mounting brackets, and the second upper pressure roller and the second lower pressure roller are mounted on two swing arm brackets. The thickness adjustment component drives the swing arm brackets to deflect around their connection point with the machine frame towards or away from the mounting brackets, so as to drive the second upper pressure roller and the second lower pressure roller to move synchronously, thereby changing the distance between the first upper pressure roller and the second upper pressure roller, as well as between the first lower pressure roller and the second lower pressure roller.

[0011] Furthermore, it also includes a material discharge plate located directly below the leveling mechanism. The material discharge plate has a discharge port, the input end of which receives the material squeezed by the leveling mechanism, and the output end connects to the cutting mechanism.

[0012] Furthermore, the cutting mechanism includes a cutting drive unit, a transmission component, and a cutting blade. The output end of the transmission component is connected to the cutting blade, and the cutting drive unit is connected to the input end of the transmission component. The cutting drive unit drives the cutting blade to move axially by driving the transmission component.

[0013] Furthermore, the conveying mechanism includes a third conveyor belt, a third transmission module, and a second conveying drive unit. The output end of the third transmission module is connected to the third conveyor belt, and the second conveying drive unit is connected to the input end of the third transmission module. The second conveying drive unit drives the third transmission module to move the third conveyor belt.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By setting up a lifting and tilting mechanism and a material conveying mechanism, the lifting and tilting mechanism is connected to the hopper and is used to drive the hopper to rise and fall vertically. After the hopper is lifted to a preset height, it tilts and tilts, so that the material in the hopper is poured onto the material conveying mechanism. The input end of the material conveying mechanism receives the material poured by the lifting and tilting mechanism, and the output end is connected to the stirring mechanism to output the material to the stirring mechanism. Workers no longer need to climb to add materials; they can simply place the rice into the liftable hopper from the ground. This significantly reduces the probability of accidents such as slipping and falling. In addition, the lifting and turning mechanism and the material conveying mechanism have automated and made the feeding process continuous, greatly shortening the feeding time and improving the overall production efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1-16 As shown, the present invention provides a sushi rice spreading device, including a machine frame 1000, on which a hopper 1001, a stirring mechanism, a leveling mechanism 500, a cutting mechanism 600 and a conveying mechanism 700 are sequentially mounted. The hopper 1001 is used to receive materials, including rice for making sushi. The stirring mechanism is used to stir and disperse the material. After the stirring mechanism stirs and disperses the material, the material falls into the leveling mechanism 500. The leveling mechanism 500 is used to press the material to a preset thickness and then output it to the conveying mechanism 700. The conveying mechanism 700 is used to convey the leveled material; The cutting mechanism 600 is located above the conveying mechanism 700. During the process of conveying materials by the conveying mechanism 700, the material is cut according to a preset length. The device also includes a lifting and tilting mechanism 100 and a material conveying mechanism 200. The lifting and tilting mechanism 100 is connected to the hopper 1001 and is used to drive the hopper 1001 to rise and fall vertically. After the hopper 1001 is lifted to a preset height, it tilts the hopper so that the material in the hopper 1001 is poured onto the material conveying mechanism 200. The material conveying mechanism 200 receives the material poured out by the lifting and tilting mechanism 100 at its input end and is connected to the stirring mechanism at its output end, for outputting the material to the stirring mechanism.

[0019] In one embodiment, the lifting and tilting mechanism 100 includes a track plate 104, a movable frame 109, a transmission assembly, and a driver 105. The track plate 104 is provided with a lifting and tilting track 106, which is used to guide the movable frame 109 to perform vertical lifting and to achieve a 90° tilting action. The output end of the transmission assembly is connected to the movable frame 109, and the driver 105 is connected to the input end of the transmission assembly. The driver 105 drives the movable frame 109 to move along the lifting and tilting track 106 by driving the transmission assembly. The movable frame 109 includes a lifting bracket 112 and a tilting bracket 110. One end of the tilting bracket 110 is rotatably connected to the lifting bracket 112 via a coupling 113. The lifting bracket 112 is equipped with a first roller group 103 that slides in cooperation with the lifting and tilting track 106. The tilting bracket 110 is equipped with a second roller group 102 that slides in cooperation with the lifting and tilting track 106. The first roller group 103 consists of at least two mutually symmetrical first rollers, and the second roller group 102 consists of at least two mutually symmetrical second rollers. The first rollers and the second rollers are configured to slide along the lifting and tilting track 106. The lifting and tilting track 106 consists of a lifting section and a tilting section. The lifting section is straight to ensure that the movable frame 109 moves linearly in the vertical direction. The first half of the tilting section is an arc-shaped groove, and the second half is a straight groove. After the movable frame 109 completes vertical lifting in the lifting section, it enters the tilting section. The radius of curvature of the arc-shaped groove is set so that the second roller group 102 is guided and constrained by the arc-shaped groove track after entering the arc-shaped groove and changes its direction of movement according to a predetermined trajectory. As the second roller group 102 slides in the arc-shaped groove, the tilting bracket 110 begins to deflect relative to the lifting bracket 112 with the movable joint 113 as the rotation center. This deflection process continues until the movable frame 109 is guided by the arc-shaped groove. After a 90° flip, the second roller group 102 enters the straight groove of the flip section and continues to slide along the straight groove until it reaches the end of the straight groove. At this time, since the flip support 110 and the lifting support 112 are rotatably connected by the movable joint 113, and after the second roller group 102 slides to the end in the straight groove of the flip section, the movement of the flip support 110 is restricted by the flip section track. Therefore, under the pushing action of the lifting support 112, its other end is deflected relative to the lifting support 112 towards the side closer to the material conveying mechanism 200 with the movable joint 113 as the rotation center, thereby realizing the accurate pouring of the material in the hopper 1001 onto the material conveying mechanism 200. In addition, the lifting bracket 112 is equipped with a first angle limiting block 114 and a second angle limiting block 115 at one end near the tilting bracket 110. The second angle limiting block 115 is configured to limit the rotation angle range of the tilting bracket 110 during the deflection process. Specifically, when the tilting bracket 110 deflects, its side will abut against the second angle limiting block 115 to limit the rotation angle range of the tilting bracket 110. The rotation angle range is set to ensure that the material will not remain in the hopper 1001 due to the tilting angle being too small during the pouring process, and to prevent the material from spilling outside the material conveying mechanism 200 due to the tilting angle being too large. The first angle limiting block 114 plays a role when the driver 105 drives the movable frame 109 to reset through the transmission component. During this process, the second roller group 102 enters the arc groove and slides. At the same time, it is pulled by the gravity of the hopper 1001. The tilting bracket 110 deflects again relative to the lifting bracket 112 with the movable joint 113 as the rotation center. At this time, the side of the tilting bracket 110 will abut against the first angle limiting block 114, thereby limiting its rotation angle range and making the hopper 1001 parallel to the horizontal plane.

[0020] In this embodiment, the hopper 1001 is detachably connected to the tilting bracket 110. This design facilitates the assembly and disassembly of the hopper 1001 and subsequent cleaning. Specifically, a support bracket perpendicular to the tilting bracket 110 is fixedly installed at the end of the tilting bracket 110 away from the connector 113 and close to the hopper 1001. L-shaped locking brackets 1002 are symmetrically mounted on both sides of the support bracket. During assembly, the hopper 1001 is first placed stably on the support bracket, ensuring that the bottom of the hopper 1001 is tightly fitted with the upper surface of the support bracket. Then, the longitudinal height of the locking bracket 1002 is adjusted. The hopper 1001 is clamped on both sides by the locking bracket 1002 and the supporting bracket. Finally, it is locked with bolts and nuts, thereby achieving a tight connection between the hopper 1001 and the tilting bracket 110. It is worth noting that the locking bracket 1002 is provided with a waist hole 1003, and the supporting bracket is provided with a connector 1004. The connector 1004 has a bolt hole that communicates with the waist hole 1003. After adjusting the locking bracket 1002 to a suitable height position, it is locked with bolts and nuts, thereby achieving a tight connection between the locking bracket 1002 and the supporting bracket. This design can adapt to hoppers 1001 of different heights.

[0021] In one embodiment, the transmission assembly includes a drive wheel 108, a driven wheel 101, and a transmission chain 107. The transmission chain 107 is wrapped around the drive wheel 108 and the driven wheel 101 to form a closed power transmission circuit. The lifting bracket 112 is equipped with a connector 111, which is configured to be locked to the transmission chain 107 by bolts, so that the lifting bracket 112 can move up and down as the transmission chain 107 moves cyclically. The driver 105 is driven to connect to the drive wheel 108 and is used to drive the drive wheel 108 to rotate around its own axis. When the drive wheel 108 rotates, it drives the transmission chain 107 to move cyclically, and the transmission chain 107 in turn drives the driven wheel 101 to rotate around its own axis, while driving the lifting bracket 112 to move up and down. The tilting bracket 110 moves up and down under the pushing or pulling action of the lifting bracket 112.

[0022] The material conveying mechanism 200 includes a conveying frame 201 and a first conveying component assembled inside the conveying frame 201. In this embodiment, the conveying frame 201 is assembled from multiple quick-release plates 204 by a quick-connect structure. The quick-release plates 204 are made of food-grade silicone material. The quick-connect structure consists of splicing protrusions 206 and splicing grooves 212 on the opposite surfaces of adjacent quick-release plates 204. The splicing protrusions 206 can be quickly embedded into the splicing grooves 212 to achieve a stable splicing of adjacent quick-release plates 204. The assembled conveying frame 201 is then fixed. The conveyor frame 201 is fixedly mounted on the machine frame 1000, and one end of the conveyor frame 201 is provided with a first discharge slot 215 for material discharge. In addition, the conveyor frame 201 is also provided with a first transmission rod 205, a locking member 214 and a plurality of connecting rods 207. At least two connecting rods 207 are provided with snap-fit ​​grooves 208, and the locking member 214 is provided with snap-fit ​​holes 213. The diameter of the snap-fit ​​hole 213 is smaller at the upper end and larger at the lower end. The locking member 214 is mounted on the outside of the conveyor frame 201, and the connecting rods 207 can pass through the snap-fit ​​hole 213.

[0023] In one embodiment, the first conveying component includes a first conveyor belt 202, a first transmission module, and a conveying drive component. The output end of the first transmission module is connected to the first conveyor belt 202, and the conveying drive component is connected to the input end of the first transmission module. The conveying drive component drives the first transmission module to move the first conveyor belt 202. The first transmission module is detachably mounted on the conveyor frame 201. The first transmission module includes a first driving roller 305, a first driven roller 209, and two frames 210. The first driven roller 209 is connected to one of the frames 210. During assembly, the first driving roller 305 is sleeved on the first transmission rod 205 of the conveyor frame 201, and the frame 210 is sleeved on the connecting rod 207 of the conveyor frame 201 through the through holes 211 provided thereon. The first driven roller 209 is mounted on the side away from the first driving roller 305 to achieve modular installation. It is worth noting that since the outer diameter of the first driven roller 209 and the first driving roller 305 is greater than the thickness of the frame 210, the first conveyor belt 202 will not touch the frame 210 when it is sleeved on the outside of the first driving roller 305 and the first driven roller 209. The first conveyor belt 202 is made of food-grade silicone material and is sleeved on the outside of the first driving roller 305 and the first driven roller 209 of the first transmission module. It is used to carry the material to be conveyed. Then, the locking member 214 on the conveyor frame 201 is pressed down so that the locking groove 208 of the connecting rod 207 is locked into the upper end of the locking hole 213 of the locking member 214, thereby realizing a stable connection between the conveyor frame 201 and the first transmission module. The conveying drive assembly includes a drive gear, a driven gear, and a first conveying drive unit 216. The driven gear is connected to the first transmission rod 205 of the conveying frame 201. The first conveying drive unit 216 drives the drive gear to rotate. The drive gear meshes with the driven gear and drives the first transmission rod 205 to rotate, thereby driving the first conveyor belt 202 to move.

[0024] The stirring mechanism includes a first stirring assembly 300 mounted above the first material discharge trough 215. In this embodiment, the first stirring assembly 300 is detachably mounted on the conveyor frame 201. The conveyor frame 201 is also provided with a second transmission rod 203 for driving the first stirring rod 304 to rotate. The first stirring assembly 300 includes a first stirring rod 304, a transmission unit, and a stirring drive unit 301. The output end of the transmission unit is connected to the first stirring rod 304, and the stirring drive unit 301 is connected to the input end of the transmission unit. The stirring drive unit 301 drives the first stirring rod 304 to rotate by driving the transmission unit, thereby stirring and dispersing the material located on the first conveyor belt 202. The material that has completed this action falls from the first material discharge trough 215. In one embodiment, the transmission unit includes a driving pulley, a driven pulley 302, and a transmission belt 303. The first stirring rod 304 is an auger and is mounted on the second transmission rod 203 of the conveyor frame 201. The driven pulley 302 is connected to the second transmission rod 203. The transmission belt 303 is mounted on the driving pulley and the driven pulley 302. The stirring drive unit 301 drives the driving pulley to rotate, and the driving pulley drives the driven pulley 302 to rotate through the transmission belt 303, thereby driving the first stirring rod 304 to rotate and realizing the dispersion and stirring of the material.

[0025] This embodiment also includes a mixing frame 401, a second conveying assembly, a storage hopper 410, and a drive assembly that are detachably mounted on the machine frame 1000. The mixing mechanism also includes a second mixing assembly 400 mounted inside the mixing frame 401. The drive assembly is connected to the second conveying assembly and the second mixing assembly 400 and is used to drive the second conveying assembly to operate to convey materials, and at the same time drive the second mixing assembly 400 to mix and disperse the materials. In one embodiment, the second stirring assembly 400 includes a second stirring rod 402 rotatably connected to the stirring frame 401 and at least two third stirring rods 403; the second stirring rod 402 is of the auger type, and the surface of the third stirring rod 403 is uniformly provided with a plurality of columnar stirring sections 404; The bottom of the mixing rack 401 is provided with an opening, and the second conveying component is located at the bottom of the mixing rack 401. Its input end receives the material falling from the first material drop trough 215, and its output end is connected to the storage hopper 410, which is used to further convey the material processed by the second mixing component 400 to the storage hopper 410. The second conveying assembly includes a second conveyor belt 405 and a second transmission module. The second conveyor belt 405 is made of food-grade silicone material. The length of the second conveyor belt 405 is less than the length of the mixing frame 401, so that a second material discharge trough is formed at the bottom of the mixing frame 401 in the area not covered by the second conveyor belt 405. The storage hopper 410 is made of food-grade silicone material and is located directly below the second material discharge trough to receive the material falling from the second material discharge trough. To drive the second stirring assembly 400, a first driven gear set 413 and a second driven gear set 414 are mounted on the side of the stirring frame 401. The drive assembly includes a drive motor 406, a transmission gear set 408, and a transmission shaft 407 mounted on the body frame 1000. The transmission gear set 408 is linked to the first driven gear set 413 and the second driven gear set 414 through the transmission shaft 407. Each synchronous gear of the first driven gear set 413 is linked through a first synchronous belt 412, and each synchronous gear of the second driven gear set 414 is linked through a second synchronous belt 411. The second stirring rod 402 is connected to one of the synchronous gears of the second driven gear set 414, and the third stirring rod 403 is connected to two of the synchronous gears of the first driven gear set 413. The drive motor 406 drives the transmission gear set 408 to rotate, and the transmission shaft 407 transmits power synchronously to the first driven gear set 413 and the second driven gear set 414 to drive the second stirring rod 402 and the third stirring rod 403 to rotate synchronously to disperse and stir the material. The second transmission module has the same structure as the first transmission module, including a second active roller, a second driven roller 409 and a frame 210. The second active roller and the second driven roller 409 are rotatably connected to the machine frame 1000. The second active roller is connected to one of the synchronous gears of the first driven gear set 413, so that the second conveying component and the second stirring component 400 operate synchronously, realizing the simultaneous transmission of materials and the dispersing and stirring of materials. It is worth noting that the first conveying component is parallel to the length direction of the machine frame 1000, and the second conveying component is parallel to the width direction of the machine frame 1000. When the rice is conveyed along the first conveying component, the first stirring component 300 stirs and disperses the rice in a first direction. When the rice is conveyed along the second conveying component, the second stirring component 400 stirs and disperses the rice in a second direction. Through the stirring and dispersing actions in two different directions, the rice can be processed in all directions and from multiple angles, thereby making the rice more evenly dispersed.

[0026] The storage hopper 410 has an opening at its bottom to form a third material discharge chute. A leveling mechanism 500 is positioned directly below the third material discharge chute to receive the material falling from it. The leveling mechanism 500 includes an upper pressure roller assembly and a lower pressure roller assembly, which are detachably mounted on the machine frame 1000 to facilitate replacement with upper and lower pressure roller assemblies of different sizes. To drive the upper and lower pressure roller assemblies, a first drive module and a second drive module are mounted on the machine frame 1000. The upper pressure roller assembly includes a first upper pressure roller 502 and a second upper pressure roller 503. The pressure roller 501 and the lower pressure roller assembly include a first lower pressure roller 503 and a second lower pressure roller 504. The first upper pressure roller 502, the second upper pressure roller 501, the first lower pressure roller 503, and the second lower pressure roller 504 are all made of food-grade silicone material. The first drive module is used to drive the first upper pressure roller 502 and the second upper pressure roller 501 to rotate in opposite directions, and the second drive module is used to drive the first lower pressure roller 503 and the second lower pressure roller 504 to rotate in opposite directions. The material falls between the first upper pressure roller 502 and the second upper pressure roller 501 and is output between the first lower pressure roller 503 and the second lower pressure roller 504. The fuselage frame 1000 is equipped with two symmetrically distributed mounting brackets 525 that are fixed relative to the fuselage frame 1000. The first upper pressure roller 502 and the first lower pressure roller 503 are mounted on the two mounting brackets 525 in an up-down distribution layout, and both the first upper pressure roller 502 and the first lower pressure roller 503 are configured to be able to rotate relative to the mounting brackets 525 around their own axis. In addition, the fuselage frame 1000 is also equipped with two symmetrically distributed swing arm brackets 505 that can rotate relative to the fuselage frame 1000. The second upper pressure roller 501 and the second lower pressure roller 504 are installed on the two swing arm brackets 505 in an up-down distribution layout, and both the second upper pressure roller 501 and the second lower pressure roller 504 are configured to rotate relative to the swing arm brackets 505 around their own axis. The first drive module includes a third driven gear set 523, a third synchronous belt 524, and a first power drive unit 510. The third driven gear set 523 includes multiple synchronous gears, two of which are respectively mounted on a fixed bracket 522 and a swing arm bracket 505. These two synchronous gears are configured to rotate relative to the fixed bracket 522 and the swing arm bracket 505 around their own axes. The synchronous gears of the third driven gear set 523 are linked together through the third synchronous belt 524. The first upper pressure roller 502 and the second upper pressure roller 501 are respectively connected to the synchronous gears in the third driven gear set 523. The first power drive unit 510 transmits power to the first upper pressure roller 502 and the second upper pressure roller 501 through the third driven gear set 523 and the third synchronous belt 524. It is worth noting that in order to make the first upper pressure roller 502 and the second upper pressure roller 501 rotate in opposite directions, an intermediate transition gear is set so that the power changes direction during transmission, thereby making the first upper pressure roller 502 and the second upper pressure roller 501 rotate in opposite directions. The second drive module includes a fourth driven gear set 515, a fourth synchronous belt 516, and a second power drive unit 512. The fourth driven gear set 515 includes multiple synchronous gears, two of which are respectively mounted on a fixed bracket 522 and a swing arm bracket 505. These two synchronous gears are configured to rotate relative to the fixed bracket 522 and the swing arm bracket 505 around their own axes. The synchronous gears of the fourth driven gear set 515 are linked together through the fourth synchronous belt 516. The first lower pressure roller 503 and the second lower pressure roller 504 are respectively connected to the synchronous gears of the fourth driven gear set 515. The second power drive unit 512 transmits power to the first lower pressure roller 503 and the second lower pressure roller 504 through the fourth driven gear set 515 and the fourth synchronous belt 516. Similarly, in order to make the first lower pressure roller 503 and the second lower pressure roller 504 rotate in opposite directions, an intermediate transition gear is provided so that the power changes direction during transmission, thereby making the first lower pressure roller 503 and the second lower pressure roller 504 rotate in opposite directions. The leveling mechanism 500 also includes a thickness adjustment component, which is configured to drive the swing arm bracket 505 to deflect. When the swing arm bracket 505 deflects around its connection point with the machine frame 1000 in a direction closer to or further away from the mounting bracket 525, it will drive the second upper pressure roller 501 and the second lower pressure roller 504 to move synchronously. This movement causes the distance between the first upper pressure roller 502 and the second upper pressure roller 501 and between the first lower pressure roller 503 and the second lower pressure roller 504 to change. Specifically, when the swing arm bracket 505 deflects towards the mounting bracket 525, the distance decreases, and when it deflects away from the mounting bracket 525, the distance increases, thereby adjusting the thickness of the rice after it is formed to meet the production needs of different specifications of rice products. To achieve the above objectives, one end of the swing arm bracket 505 is rotatably connected to the fuselage frame 1000 via a pivot 520. Furthermore, the fuselage frame 1000 is provided with a waist hole 1003 for the swing arm bracket 505 to rotate. This waist hole 1003 can guide the movement trajectory of the swing arm bracket 505 and limit the maximum rotation angle range of the swing arm bracket 505. The thickness adjustment assembly includes a third power drive unit 509, a connecting shaft 508, and a set of symmetrically distributed connecting components. The connecting components include connecting pieces 507 and transmission brackets 506. The connecting pieces 507 are respectively assembled at both ends of the connecting shaft 508 and connected to it. One end of the transmission bracket 506 is rotatably connected to the connecting piece 507 through a rotating shaft 526, and the other end is rotatably connected to the swing arm bracket 505 through a rotating shaft 526. It is worth noting that during the thickness adjustment process, the swing arm bracket 505 rotates around the rotating shaft 520 as the rotation center, while the transmission bracket 506 needs to be adjusted accordingly according to the movement posture of the swing arm bracket 505. The rotating shaft 526 can provide multiple degrees of freedom of rotation, so that the transmission bracket 506 can flexibly adapt to the movement of the swing arm bracket 505 and ensure the smoothness of power transmission. The third power drive unit 509 transmits power to the connecting piece 507 through the connecting shaft 508. Under the action of power, the connecting piece 507 pushes the swing arm bracket 505 to deflect relative to the machine frame 1000 with the rotating shaft 520 as the rotation center through the transmission bracket 506, thereby adjusting the distance between the first upper pressure roller 502 and the second upper pressure roller 501 and the first lower pressure roller 503 and the second lower pressure roller 504, and thus adjusting the thickness of the rice after it is formed. To solve the problem of synchronous belt tension caused by the movement of the second upper pressure roller 501 and the second lower pressure roller 504, in this embodiment, the waist hole 1003 on the machine frame 1000 is designed to be inclined upward, and the swing arm bracket 505 near the third power drive unit 509 is set as a hollow frame structure, and an active groove 519 penetrating its side is provided on the swing arm bracket 505. The following assembly is performed on the swing arm bracket 505: a movable rod 518, a fixed rod 511, and a spring are assembled. The fixed rod 511 is fixed relative to the swing arm bracket 505. The movable rod 518 is configured to move inside the swing arm bracket 505. Specifically, both ends of the movable rod 518 are located inside the movable groove 519 and can move along the movable groove 519. The tension wheel 517 is sleeved on the outside of the movable rod 518 and rotatably connected to it. The fixed rod 511 is provided with a through hole 211. The movable rod 518 is equipped with a lifting rod. The spring is sleeved on the lifting rod, and the lifting rod passes through the through hole 211. Under the action of the spring force, the movable rod 518 is subjected to a vertically downward force. When the swing arm bracket 505 deflects, and the tension of the timing belt changes due to the movement of the second upper pressure roller 501 and the second lower pressure roller 504, the spring force will drive the movable rod 518 to move in the movable groove 519, automatically adjusting the contact position between the tensioning wheel 517 and the timing belt to maintain a suitable tension of the timing belt. At the same time, since the waist hole 1003 is tilted upward, the roller shafts of the second upper pressure roller 501 and the second lower pressure roller 504 will move along the waist hole 1003, and the trajectory of the movable rod 518 moving in the movable groove 519 is the same as the direction of the upward tilting waist hole 1003 on the machine frame 1000. Furthermore, the machine frame 1000 is equipped with two spaced-apart baffles 521, and the baffles 521 are detachably connected to the machine frame 1000 to facilitate subsequent adjustment of the spacing between the two baffles 521. One side of the baffle 521 has a first arc surface, which is in contact with the roller shafts of the first upper pressure roller 502 and the first lower pressure roller 503. The other side has a second arc surface. When the second upper pressure roller 501 and the second lower pressure roller 504 move to their maximum displacement value, their... The roller shaft will be in contact with the second arc surface. It is worth noting that the roller shafts of the second upper pressure roller 501 and the second lower pressure roller 504 do not necessarily have to be in contact with the second arc surface. The baffle 521 can block the material. During the operation of the equipment, the material can only fall between the first upper pressure roller 502 and the second upper pressure roller 501 under the obstruction of the baffle 521. Furthermore, the distance between the two baffles 521, as well as the specifications of the upper pressure roller assembly and the lower pressure roller assembly, together determine the width of the rice forming.

[0027] It also includes a material discharge plate 607 located directly below the leveling mechanism 500. The material discharge plate 607 has a material discharge port 606. The input end of the material discharge port 606 receives the material squeezed by the leveling mechanism 500, and the output end is connected to the cutting mechanism 600. The cutting mechanism 600 includes a cutting drive unit 601, a transmission component, and a cutting blade 605. The output end of the transmission component is connected to the cutting blade 605, and the cutting drive unit 601 is connected to the input end of the transmission component. The cutting drive unit 601 drives the cutting blade 605 to move axially by driving the transmission component. The transmission components in this embodiment include an eccentric shaft 602, a guide block 608, a movable block 603, a guide rod 609, and a push plate 604. The guide block 608 is fastened to the machine frame 1000. One end of the guide rod 609 is fastened to the movable block 603, and the other end passes through the guide block 608 and is connected to the push plate 604. An eccentric section is provided on the eccentric shaft 602. A hole adapted to the eccentric section is opened on the movable block 603. The eccentric shaft 602 is inserted into the hole. The cutting drive unit 601 is connected to the eccentric shaft 602. In the production process, the material begins to fall from the feed port 606. As the material continues to fall, when it reaches the appropriate position, the cutting drive unit 601 drives the eccentric shaft 602 to rotate. The eccentric motion of the eccentric section drives the movable block 603 to perform reciprocating linear motion. The reciprocating linear motion of the movable block 603 is transmitted to the push plate 604 through the guide rod 609. The push plate 604 then drives the cutting blade 605 to perform axial motion, ultimately cutting the material.

[0028] The conveying mechanism 700 includes a third conveyor belt 704, a third transmission module, and a second conveying drive unit 701. The output end of the third transmission module is connected to the third conveyor belt 704, and the second conveying drive unit 701 is connected to the input end of the third transmission module. The second conveying drive unit 701 drives the third transmission module to move the third conveyor belt 704. The third transmission module has the same structure as the first transmission module, including a third driving roller 702, a third driven roller 703, and at least two frames 210. The third conveyor belt 704 is made of food-grade silicone material and is sleeved on the outside of the third driving roller 702 and the third driven roller 703 of the third transmission module to carry the material to be conveyed. The second conveying drive unit 701 is connected to the third driving roller 702. By driving the third driving roller 702 to rotate, it drives the third conveyor belt 704 and the third driven roller 703 to rotate synchronously, thereby realizing the conveying of materials.

[0029] Compared to traditional technologies: By setting up a lifting and tilting mechanism 100 and a material conveying mechanism 200, wherein the lifting and tilting mechanism 100 is connected to the hopper 1001, and is used to drive the hopper 1001 to rise and fall vertically, and after the hopper 1001 is lifted to a preset height, it performs a tilting action, so that the material in the hopper 1001 is poured onto the material conveying mechanism 200. The input end of the material conveying mechanism 200 receives the material poured out by the lifting and tilting mechanism 100, and the output end is connected to the stirring mechanism, and is used to output the material to the stirring mechanism. Workers no longer need to climb to add materials; they can simply place the rice into the liftable hopper 1001 from the ground. This significantly reduces the probability of accidents such as slipping and falling. In addition, the lifting and turning mechanism 100 and the material conveying mechanism 200 automate and make the feeding process continuous, greatly shortening the feeding time and improving the overall production efficiency.
