[0044] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0045] The overall structure of this case is as follows Figure 1 As shown, along the material conveying direction, a feeding mechanism 1, a blanking mechanism 2, a forming mechanism 3 and a discharging mechanism 4 are included in sequence, the forming mechanism 3 and the discharging mechanism 4 are installed on a workbench 9, the feeding mechanism 1 is installed on a frame on the workbench 9, and the blanking mechanism 2 is installed between the feeding mechanism 1 and the forming mechanism 3; when in use, after the rice is directly put into the feeding mechanism 1, the clumped rice is raked loose by the feeding mechanism 1 to complete the feeding, and then the blanking mechanism 2 guides and conveys the rice, and finally falls into the forming mechanism 3 in a quantitative manner to form the rice ball. After the forming is completed and the demoulding is completed, the discharging mechanism 4 conveys the final rice ball out. The overall work does not require manual intervention and has a high degree of automation, thereby realizing a series of automatic processing of rice balls such as feeding, blanking, pressing and discharging.

[0046] Regarding the feeding mechanism, in the field of food cold chain supply, the raw materials for the processing of sushi rice balls of various shapes are usually cooked rice, and different forming molds are usually used for pressing and forming. However, cooked rice is usually sticky and lumpy, which makes it extremely difficult to control the quantitative amount of rice when forming rice balls. Therefore, how to rake and loosen the cooked rice for quantitative output has become a technical problem that needs to be solved urgently by technicians in this field.

[0047] Accordingly, this case specifically proposes Figure 2-1 , 2-2 The feeding mechanisms shown in 2-3, 2-4, 2-5 and 2-6 can automatically rake and loosen the clumped rice during the conveying process to facilitate subsequent quantitative control.

[0048] The feeding mechanism 1 includes a feeding bin 11 and a rake bin 12 fixedly mounted on a frame, a top opening docking with the feeding bin 11 is opened on the rear side of the top surface of the rake bin 12, and a discharge port 120 is opened on the front side of the bottom surface of the rake bin 12, the rake bin 12 is provided with a feeding conveyor belt 121 arranged along its length direction, and a rotating rake 122, a gathering auger 123 and a fixed rake 124 are arranged above the feeding conveyor belt 121; the rotating rake 122 and the gathering auger 123 are both rotatably connected in the rake bin 12, and the rotating rake 122 is located on the rear side of the gathering auger 123, and the fixed rake 124 is fixedly mounted in the rake bin 12. In this way, after the clumping rice enters the rake and loosen bin 12 through the feed bin 11, it will be transported from the back to the front driven by the feed conveyor belt 121, and will be evenly and efficiently raked and loosened when passing through the rotating rake 122 and the fixed rake 124. Finally, the gathering auger 123 is responsible for leading the raked and loosened rice to the discharge port 120. Overall, it has the advantages of good rake and loosen effect, high work efficiency and good work stability.

[0049] A feeding drive unit 13 for driving a feeding conveyor belt 121 , a rotating harrow 122 , and a gathering auger 123 is installed on the side wall of the harrowing bin 12 .

[0050] The rotating rake 122 has a plurality of rake loosening teeth arranged along its radial direction, and the fixed rake 124 has a plurality of evenly distributed fixed teeth, and the movement trajectory of the rake loosening teeth passes through the gaps between adjacent fixed teeth. In this way, when the rice in a ball form passes through the area where the two are located, it will first contact the rake loosening teeth, and then be raked and conveyed forward under the guidance of the feeding conveyor belt 121 and the raking and loosening action of the rotating rake 122. As for the rice passing through the gaps between the rake loosening teeth, it will contact the fixed teeth, so that the rice adhering to the rake loosening teeth can be raked off by the fixed teeth, and finally, it can be ensured that after passing through the cross-arranged rotating rake 122 and the fixed rake 124, the rice in a ball form can be efficiently raked loose and spread on the feeding conveyor belt 121.

[0051] The fixed teeth are arranged obliquely downward toward the area where the rotating rake 122 is located, so as to cooperate with the loosening teeth to better loosen the clumped rice.

[0052] Affected by the rotating rake 122 and the fixed rake 124, the rice clumps will be unevenly spread on the feeding conveyor 121 after being raked loose. In order to concentrate the discharge and control the discharge amount of the loosened rice, the present invention also proposes a gathering auger, and the gathering auger 123 is a bidirectional auger symmetrical along the center. Thus, the purpose of gathering the discharged rice to the center of the discharge port 120 is achieved, and the discharge amount of the loosened rice is further controlled.

[0053] Regarding the feed drive unit 13 driving the feed conveyor 121, the rotating rake 122, and the gathering auger 123, considering that the rotating rake 122 and the gathering auger 123 both have a central axis rotatably connected to the rake loosening bin 12, and the feed conveyor 121 includes a driving shaft rotatably connected to the rake loosening bin 12, a driven shaft, and a conveyor belt wound therebetween, therefore, the final output target of the feed drive unit 13 is the central axis of the rotating rake 122, the central axis of the gathering auger 123, and the driving shaft of the feed conveyor 121, specifically:

[0054] The feed drive unit 13 includes a feed drive motor 131 and a feed transmission gear set 132. The housing of the feed drive motor 131 is fixedly mounted on the side wall of the harrowing bin 12. The output shaft of the feed drive motor 131 is connected to the central axis of the rotating harrow 122, the central axis of the gathering auger 123 and the driving shaft of the feed conveyor belt 121 through the feed transmission gear set 132.

[0055] The feed transmission gear set 132 includes gear 1 1321, gear 2 1322, gear 3 1323, gear 4 1324, gear 5 1325, gear 6 1326, gear 7 1327 and gear 8 1328, wherein the gear 1 1321 is fixedly sleeved on the output shaft of the feed drive motor 131, the gear 3 1323 is fixedly sleeved on the driving shaft of the feed conveyor belt 121, the gear 5 1325 is fixedly sleeved on the central axis of the gathering auger 123, the gear 8 1328 is fixedly sleeved on the central axis of the rotating rake 122, and the gear 2 1322, gear 4 1324, gear 6 1326 and gear 7 1327 are rotatably connected to the side wall of the rake loosening bin 12;

[0056] The gear two 1322, gear three 1323, and gear four 1324 are all double gears, the gear one 1321 is meshed with the large gear of gear two 1322, and the large gear of gear two 1322 is meshed with the small gear of gear three 1323, so as to realize the power transmission from the feed drive motor 131 to the feed conveyor belt 121; the large gear of gear three 1323 is meshed with the small gear of gear four 1324, and the large gear of gear four 1324 is meshed with gear five 1325, so as to realize the power transmission from the feed drive motor 131 to the gathering auger 124; the large gear of gear two 1322 is also meshed with gear six 1326, and the gear six 1326, gear seven 1327, and gear eight 1328 are meshed in sequence, so as to realize the power transmission from the feed drive motor 131 to the rotating rake 122.

[0057] In this way, gear three 1323, gear five 1325, and gear eight 1328 can rotate synchronously with the same rotation direction and the same or different speeds. Further, the conveying direction of the feed conveyor belt 121 can be opposite to the rotation direction of the rotating rake 122 and the gathering auger 123, so as to ensure the efficient raking and loosening of the rice and the subsequent centralized output.

[0058] Regarding the feeding mechanism, it is necessary to receive the rice delivered by the feeding mechanism and output it quantitatively after proper squeezing. Specifically, Figure 3-1 , 3-2 , 3-3, 3-4, 3-5, 3-6 as shown:

[0059] The blanking mechanism 2 includes a front baffle 21 and a rear baffle 22 fixedly mounted on the frame, a pair of upper pressing wheels 23 and a pair of lower pressing wheels 24 rotatably connected between the front baffle 21 and the rear baffle 22, and a pair of shearing plates 26 slidably connected below the front baffle 21 and the rear baffle 22;

[0060] A material drop box is fixedly installed on the top of the front baffle 21 and the rear baffle 22, and a feed port 20 is provided in the material drop box, which is connected to the discharge port 120 in the rake loosening bin 12. The centers of the side wall wheel surfaces of the upper pressing wheel 23 and the lower pressing wheel 24 are both recessed inward, and the spacing between the pair of lower pressing wheels 24 is smaller than the spacing between the pair of upper pressing wheels 23, so that a gradually closing material drop channel is formed between the pair of upper pressing wheels 23 and the pair of lower pressing wheels 24, and the shear plate 26 is at the bottom of the material drop channel. In this way, the rice loosened by the feed mechanism can be received by the material drop mechanism, and the shear plate 26 can be used to control whether the material drop channel is discharged, thereby achieving the purpose of quantitative discharge.

[0061] A roller drive unit 25 for driving a pair of upper rollers 23 and a pair of lower rollers 24 to rotate is provided at the rear of the rear baffle 22. The roller drive unit 25 includes an upper motor 251 and a lower motor 252. The housing of the upper motor 251 is fixedly mounted on the frame and is located at the rear side of the upper roller 23. The output shaft of the upper motor 251 is connected to the two upper rollers 23 through a transmission gear, and the upper motor 251 drives the pair of upper rollers 23 to rotate synchronously in the opposite direction. The housing of the lower motor 252 is fixedly mounted on the frame and is located at the rear side of the lower roller 24. The output shaft of the lower motor 252 is connected to the two lower rollers 24 through a transmission gear, and the lower motor 252 drives the pair of lower rollers 24 to rotate synchronously in the opposite direction. Thus, the upper roller 23 and the lower roller 24 are used to perform gradual squeezing and folding.

[0062] A shearing drive unit 27 for driving a pair of shearing plates 26 to synchronously reciprocate in the opposite direction is provided at the rear of the rear baffle 22. The shearing drive unit 27 includes a shearing drive motor 271 and a crank slider mechanism 272. The housing of the shearing drive motor 271 is fixedly mounted on the frame, and the output shaft of the shearing drive motor 271 is connected to two sets of crank slider mechanisms 272. The sliders in the two sets of crank slider mechanisms 272 synchronously reciprocate in the opposite direction and are respectively fixedly connected to a pair of shearing plates 26. Thus, the blanking channel is closed when the shearing plates 26 are brought together, and the blanking channel is opened when the shearing plates 26 are separated.

[0063] Regarding the molding mechanism and the discharging mechanism, such as Figure 4-1 , 4-2 , 4-3, 4-4, 4-5, 4-6, 4-7, 4-8, 4-9 as shown:

[0064] The forming mechanism 3 includes a forming mold 31 rotatably connected to the workbench 9 and a forming press block 34 arranged above the forming mold 31 through a press block driving unit 35. A part of the forming mold 31 is located directly below the blanking channel, and the forming mold 31 rotates under the drive of the mold driving unit 33. A plurality of mold cavities 311 are opened in the forming mold 31. The shape of the forming press block 34 is adapted to the mold cavity 311, and the forming press block 34 is driven to reciprocate up and down by the press block driving unit 35. In this way, the mold driving unit 33 can drive the mold cavity 311 to be directly below the blanking channel. At this time, the blanking channel is opened for quantitative discharge, so that a certain amount of rice can fall into the mold cavity 311; thereafter, the mold driving unit 33 can drive the mold cavity 311 to move to the bottom of the forming block 34, and then the forming block 34 can be driven downward by the block driving unit 35 to press the rice ball into a predetermined shape. The forming process does not require human participation, and the automated forming effectively avoids a series of defects such as slow efficiency, high labor intensity, high labor cost, uneven product quality, and high food hygiene risks in manual pressing.

[0065] In order to facilitate the discharge after molding, the following demoulding methods are also proposed in this case:

[0066] A planar cam disc 32 is also fixedly mounted on the workbench 9. The bottom of the molding die 31 is accommodated in the planar cam disc 32. A demoulding slider 321 adapted thereto is provided in each mold cavity 311 of the molding die 31. A guide wheel 322 is rotatably connected to the bottom of the demoulding slider 321. A guide step 323 is also provided in the planar cam disc 32. With the rotation of the molding die 31, the movement track of the guide wheel 322 passes through the guide step 323. In this way, the position of the guide step 323 can be set as the demoulding and discharging position. When the demoulding slider 321 and the guide wheel 322 move to the demoulding and discharging position with the mold cavity 311, the guide wheel 322 will contact the guide step 323, thereby lifting the demoulding slider 321 to achieve demoulding, so as to facilitate the convenient material removal or discharging.

[0067] The mold driving unit 33 includes a mold driving motor 331, a transmission belt 332 and a central shaft 333. The housing of the mold driving motor 331 is fixedly mounted on the workbench 9, and the central shaft 333 is rotatably connected to the workbench 9. The central shaft 333 passes through the plane cam plate 32 from bottom to top and is fixedly connected to the molding mold 31. The transmission belt 332 sequentially passes around the mold driving motor 331 and the central shaft 333. In this way, the mold driving motor 331 can drive the central shaft 333 to rotate via the transmission belt 332, thereby achieving the purpose of driving the molding mold 31 to rotate.

[0068] The pressing block driving unit 35 includes a pressing block driving motor 350, a connecting rod 1 351, a connecting rod 2 352, a lever 353, a guide column 354, a guide sleeve 355 and a pressing block mounting plate 356. The shell of the pressing block driving motor 350 is fixedly mounted on the workbench 9, the middle part of the lever 353 is hinged on the workbench 9, the output shaft of the pressing block driving motor 350, the connecting rod 1 351, the connecting rod 2 352 and a section of the lever 353 are hinged in sequence, the other end of the lever 353 is hinged to the guide column mounting plate, the bottom end of the guide column 354 is mounted on the guide column mounting plate and is slidably connected to the guide column mounting plate, the guide sleeve 355 is fixedly connected to the workbench and is mounted on the guide column 354, the top end of the guide column 354 is fixedly connected to the pressing block mounting plate 356, and the forming pressing block 34 is connected below the pressing block mounting plate 356. In this way, after the pressing block driving motor 350 is turned on, the crank rocker mechanism formed by the connecting rod 1 351 and the connecting rod 2 352 can drive a section of the lever 353 to reciprocate and rise and fall, thereby driving the guide column 354 at the other end of the lever 353 to reciprocate and rise and fall along the guide sleeve, and finally achieving the purpose of driving the forming pressing block 34 to reciprocate and rise and fall, and with the help of the lever 354, the forming pressure and forming efficiency during rice ball forming can be effectively guaranteed. Compared with manual pressing, it effectively avoids a series of defects such as slow efficiency, high labor intensity, high labor cost, uneven product quality and high food hygiene risk.

[0069] Regarding the installation of the forming press block 34, a guide rod penetrating the press block mounting plate 356 is fixedly connected to the forming press block 34, and a spring is sleeved on the guide rod. The top of the guide rod is fixedly connected to a limit block, and the spring is pressed between the forming press block 34 and the bottom surface of the press block mounting plate 356. In this way, the pressure can be controlled by the spring. When the press block mounting plate 356 moves downward excessively or the downward pressure is too large, the action of the spring will be overcome, and a small relative movement will be generated with the forming press block 34, thereby offsetting part of the excessive downward pressure, and achieving the purpose of the spring controlling the forming pressure.

[0070] Regarding the discharging mechanism, Figure 4-9 As shown, the discharging mechanism 4 includes a discharging conveyor belt 41, a discharging pusher 42, a conveyor belt driving unit 43 and a pusher driving unit 44. The discharging conveyor belt 41 is horizontally arranged in front of the molding mold 31, and performs circumferential motion under the drive of the conveyor belt driving unit 43.
