[0023] 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.

[0024] Regarding the molding mechanism and the discharging mechanism, such as Figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9 as shown:

[0025] The forming mechanism 3 includes a forming mold 31 rotatably connected to the workbench and a forming block 34 arranged above the forming mold 31 by a block driving unit 35. The forming mold 31 rotates under the drive of the mold driving unit 33. A plurality of mold cavities 311 are provided in the forming mold 31. The shape of the forming block 34 matches the mold cavity 311. The forming block 34 is driven by the block driving unit 35 to reciprocate up and down. In this way, the mold cavity 311 can be moved to the feeding position by the drive of the mold driving unit 33, and then a certain amount of rice can be put into the mold cavity 311. Thereafter, the mold cavity 311 can be driven by the mold driving unit 33 to move to the bottom of the forming block 34, and then the forming block 34 can be driven by the block driving unit 35 to press down, so that the rice ball of a predetermined shape can be pressed and formed. The forming process does not require manual participation. Through automatic forming, a series of defects such as low efficiency, high labor intensity, high labor cost, uneven product quality, and high food hygiene risk in manual pressing can be effectively avoided.

[0026] In order to facilitate the discharge after molding, the following demoulding methods are also proposed in this case:

[0027] A planar cam disc 32 is also fixedly mounted on the workbench. 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 collection or discharging.

[0028] 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, and the central shaft 333 is rotatably connected to the workbench. 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.

[0029] 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 installed on the workbench, the middle part of the lever 353 is hinged on the workbench, 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 installed 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.

[0030] 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.

[0031] Regarding the discharging mechanism, such as Fig. 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. The discharging pusher 42 is horizontally arranged above the molding mold 31. One end of the discharging pusher 42 is fixedly connected to a vertical rotating shaft, and the vertical rotating shaft is rotatably connected to the workbench and is connected to the pusher driving unit 44 through a crank rocker mechanism, so that the discharging pusher 42 is driven to swing back and forth through the pusher driving unit 44.

[0032] There are many specific implementation ways of the utility model. The above is only the preferred implementation mode of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the utility model, and these improvements should also be regarded as the protection scope of the utility model.
