It should be noted that the material mentioned in this embodiment is oil-immersed chili for preparing the hotpot condiment.

The bucket elevator 50 of the present invention lifts and pours the material into the spiral storage hopper 20, the spiral storage hopper 20 delivers the material into the multi-head scale 30 at a constant speed, the multi-head scale 30 accurately weighs the material and makes the weighed material fall into the material box 431 of the feeding and temporary storage device 40. If the weight of the material in each magazine 431 is the same, several magazines 431 can be charged. The whole process does not need manual operation, and the feeding efficiency is higher.

Batch charging temporary storage device 40:

as shown in fig. 3 to 5, the feeding temporary storage device 40 includes a feeding frame 41, the feeding frame 41 is disposed at the lower side of the multi-head scale 30, a transmission driving mechanism 42 is installed on the feeding frame 41, an output end of the transmission driving mechanism 42 is connected with a conveyor belt 43, a plurality of material boxes 431 are connected to the conveyor belt 43 through hinges, a guide rail 44 is installed on the feeding frame 41, the guide rail 44 surrounds and supports the plurality of material boxes 431, the guide rail 44 is provided with a notch 441, an opening and closing mechanism 45 is connected to the feeding frame 41, and the opening and closing mechanism 45 is located at the lower side of the notch 441 of the guide rail 44.

The feeding rack 41 is connected with a temporary storage rack 46, the temporary storage rack 46 is positioned at the lower side of the gap 441 of the guide rail 44, a plurality of temporary storage boxes 461 are arranged on the temporary storage rack 46, and the lower ends of the temporary storage boxes 461 are open; the two sides of the temporary storage frame 46 are provided with semi-closed frames 47, the two semi-closed frames 47 are sleeved on the lower sections of the temporary storage boxes 461 after being spliced, and the temporary storage frame 46 is connected with a discharging mechanism 48 for opening or closing the two semi-closed frames 47.

During operation, weighed materials are sequentially put into each material box 431 by the multi-head scale 30, and the conveyor belt 43 drives the material boxes 431 to move. When the magazine 431 moves to the area of the notch 441 of the guide rail 44, it is supported by the opening and closing mechanism 45. When the plurality of material boxes 431 filled with the materials are full on the opening and closing mechanism 45, the conveyor belt 43 stops for a period of time, and the opening and closing mechanism 45 descends, so that the plurality of material boxes 431 can be fed simultaneously, and the working efficiency is correspondingly improved. When the opening and closing mechanism 45 is lowered, the materials of the plurality of material cartridges 431 are respectively put into the plurality of temporary storage boxes 461. After the conveyor on the lower side of the buffer 46 is moved into position, the discharging mechanism 48 opens the two semi-closed frames 47, so that a plurality of buffer boxes 461 are discharged simultaneously.

The temporary storage rack 46 is provided with a material detection mechanism 511, and the material detection mechanism 511 is aligned with the lower end of the temporary storage box 461 and is used for detecting whether the temporary storage box 461 is in a discharging state or not.

Furthermore, the temporary storage rack 46 is provided with a plurality of anti-falling boxes 462, the anti-falling boxes 462 are opened towards one side of the gap 441 of the guide rail 44, and the lower parts of the anti-falling boxes 462 are communicated with the temporary storage box 461. When the material in the material box 431 is poured into the temporary storage box 461, the anti-falling box 462 can block the material to prevent the material from being scattered. The material enters the temporary storage box 461 through the anti-falling box 462, thereby ensuring the material to be scattered in the transferring process.

Specifically, the discharging mechanism 48 includes a discharging cylinder 481 installed on the temporary storage rack 46, two connecting rods 482 are hinged on a piston rod of the discharging cylinder 481, the connecting rods 482 are hinged with a lower section of the semi-closed frame 47, and an upper section of the semi-closed frame 47 is hinged with the outermost temporary storage box 461. When the piston rod of the discharging cylinder 481 extends, the two connecting rods 482 move to push the lower ends of the two semi-closed frames 47 to be spread in directions away from each other, so that the bottom opening of the temporary storage box 461 is exposed, and materials can be accurately thrown out from the temporary storage box 461 onto the conveying device.

In order to avoid interference, an opening is arranged at the upper section of the semi-closed frame 47, and a position-giving plate 471 is arranged at the opening at the upper section of the semi-closed frame 47. When the link 482 pushes the lower end of the semi-closed frame 47 to open, the semi-closed frame 47 rotates around the upper end hinge point. Since an opening is formed between the position-letting plate 471 and the semi-closed frame 47, the position-letting plate 471 does not block the semi-closed frame 47 from rotating, so as to avoid movement interference. When the semi-enclosed frame 47 is rotated to a proper position, the position plate 471 can be attached to the side surfaces of the plurality of temporary storage boxes 461, so as to seal the side surfaces of the temporary storage boxes 461.

In order to reduce the material scattering, the lower end of the semi-closed frame 47 is provided with a material baffle bent away from the other side of the semi-closed frame 47. The striker plate is arranged at the lower end of the semi-closed frame 47, so that when the two semi-closed frames 47 are opened, the striker plate can block materials, and the materials are prevented from spilling.

In order to ensure smooth passage of the magazine 431 through the opening region of the rail 44, the end of the rail 44 facing the magazine 431 is formed in an arc shape. When magazine 431 moves out of or into guide rail 44, magazine 431 passes through the arc position of the end of guide rail 44, thereby avoiding guide rail 44 from being stuck to magazine 431 and ensuring that magazine 431 can pass through the end of guide rail 44 smoothly.

Specifically, transmission actuating mechanism 42 includes drive motor, and drive motor's output is connected with the transmission reduction gear, and drive motor and transmission reduction gear install in throwing material frame 41, and the output of transmission reduction gear is connected with driving pulley 421, still rotates on throwing material frame 41 to be connected with driven pulley 422, and conveyer belt 43 transmission is connected between driving pulley 421 and driven pulley 422. The driving motor drives the transmission reducer to act, and the transmission reducer drives the driving pulley 421 to rotate, so that the transmission belt 43 continuously moves between the driving pulley 421 and the driven pulley 422. The driving belt wheel 421 and the driven belt wheel 422 are located in the same horizontal plane, so that the conveying belt 43 moves in the horizontal plane, and the material box 431 is kept opening and closing upwards under the limiting effect of the conveying belt 43 and the guide rail 44, so that the materials are prevented from being scattered.

Furthermore, a plurality of tension pulleys 423 are installed on the feeding frame 41, and the tension pulleys 423 are in transmission connection with the conveyor belt 43. The tensioning wheel 423 can tension the conveyor belt 43, and ensures that the position of the magazine 431 on the conveyor belt 43 is determined, so that the magazine 431 can accurately transfer materials at the position of the notch 441 of the guide rail 44.

Specifically, the opening and closing mechanism 45 comprises an opening and closing cylinder 451, the opening and closing cylinder 451 is hinged to the feeding rack 41, a piston rod of the opening and closing cylinder 451 is hinged to an opening and closing plate 452, the other end of the opening and closing plate 452 is hinged to the feeding rack 41, and the opening and closing plate 452 is located on the lower side of a notch 441 of the guide rail 44. When the piston rod of the opening/closing cylinder 451 is raised, the opening plate 452 is pushed up, and the opening plate 452 supports the magazine 431. When all the material boxes 431 on the opening plate 452 are filled with the materials, the piston rod of the opening cylinder 451 descends, the opening plate 452 rotates downwards, and all the material boxes 431 in the area of the notch 441 of the guide rail 44 rotate downwards to pour out the materials.

The material put into the material box 431 can be hot pepper for preparing hot pot material, thereby avoiding manual ingredients.

At this time, the second lift shaft 58 is located on the upper side of the first lift shaft 57, and the second lift shaft 58 slides in the guide chute 59, and the opening of the lift bucket 56 is upward and lifted upward. When the second lifting shaft 58 moves to the bent section of the guide chute 59, the first lifting shaft 57 continues to rise, which inevitably drives the elevator bucket 56 to turn, so that the material in the elevator bucket 56 can be sufficiently dumped. When the chain 52 is driven in reverse by the lift drive mechanism 55, the lift bucket 56 resumes an open upward direction and descends. In the whole process, the elevator bucket 56 is only turned over when the material is poured, so that the material in the elevator bucket 56 is prevented from being spilled.

The smooth transition of the guide chute 59 ensures that the second lifting shaft 58 smoothly transitions from the vertical section of the guide chute 59 to the bent section, and accordingly ensures that the lifting bucket 56 can pour materials stably.

The bi-directional motor 551 can drive the main shaft to rotate in forward and reverse directions so that the chain 52 can move in forward and reverse directions. Accordingly, the bucket 56 can be raised and lowered without tipping over.

The two ends of the second lifting shaft 58 are also connected with bearings, so that the bearings roll in the guide sliding grooves 59, and the moving smoothness of the second lifting shaft 58 is improved.

Further, as shown in fig. 8, a detection mechanism 511 for detecting the position of the lift bucket 56 is mounted on the lift frame 51, and the detection mechanism 511 is connected to the drive sprocket shaft 53. The sensing mechanism 511 determines the position of the elevator car 56 by sensing the number of rotations of the drive sprocket shaft 53 to facilitate sensing whether the elevator car 56 is at the highest or lowest point.

In order to ensure safety, the lifting frame 51 is connected with a rotating shaft box cover 512, the driving chain wheel shaft 53 and the detection mechanism 511 are both positioned in the rotating shaft box cover 512, and a handle is arranged on the rotating shaft box cover 512. The shaft box cover 512 can protect the driving sprocket shaft 53 and the shaft box cover 512, and avoid the situation that the lifting bucket 56 descends to exceed the limit position to crush the driving sprocket shaft 53 or the detection mechanism 511 when the equipment fails.

Specifically, the lift bucket 56 includes a lift frame 561, and a bucket 562 is disposed in the lift frame 561. Charging bucket 562 is replaceable, and is convenient for lifting and pouring different materials.
