[0041] Please refer to Figures 1 to 2 , Figures 4 to 5 and Figures 7 to 8, a hollow cavity 34 is provided inside the support frame 3, and a transfer plate 5 is connected to the hollow cavity 34. The transfer plate 5 slidably penetrates through the hollow cavity 34. A through hole 51 is provided on the transfer plate 5, and the through hole 51 communicates the feeding port 33 with the screen 11;

[0042] In this embodiment, the top inside the feeding port 33 is tapered, so as to ensure that the flour can stably enter the feeding port 33. An auxiliary feeding mechanism 4 is provided on the support frame 3 and extends to the feeding port 33, and the auxiliary feeding mechanism 4 is used for auxiliary feeding of the flour bags at the feeding port 33;

[0043] Please refer to Figures 5 to 6 , the auxiliary feeding mechanism 4 includes a lifting rod 41, a fixing plate 42, a lifting member 43 and a moving member 44. The lifting rod 41 is U-shaped, and a reinforcing rib is provided in the lifting rod 41 to ensure the lifting strength of the lifting rod 41. The lifting rod 41 is used for bending and lifting the flour bag placed at the feeding port 33, so that the flour at the front section of the flour bag is poured into the feeding port 33;

[0044] There are two fixing plates 42, and the two fixing plates 42 are respectively fixedly installed at the feeding port 33, and the two fixing plates 42 are respectively slidably sleeved on the outer sides of both ends of the lifting rod 41. There are two lifting members 43, and the two lifting members 43 are located on the feeding table surface 32, and the two lifting members 43 are used for driving both ends of the lifting rod 41.

[0045] The lifting member 43 includes a connecting seat 431, a connecting support rod 432, a rotating support rod 433, a fixing seat 434, a moving block 435, a lifting member 45 and a buffer member 46. The connecting seat 431 is fixedly installed at one end of the top of the lifting rod 41. One end of the connecting support rod 432 is rotatably connected to the connecting seat 431 through a rotating shaft, and the other end of the connecting support rod 432 is rotatably connected to the rotating support rod 433 through a rotating shaft. One end of the rotating support rod 433 is rotatably connected to the fixing seat 434 through a rotating shaft, and the fixing seat 434 is fixedly installed on one side of the moving block 435. At the same time, in this embodiment, preferably two connecting support rods 432 are provided, and both ends of the two connecting support rods 432 are rotatably connected to the rotating support rod 433 and the connecting seat 431 respectively. The moving block 435 is slidably connected to the feeding table surface 32, and the moving block 435 is connected to the moving member 44;

[0046] The lifting member 45 is installed on the moving block 435, and the lifting member 45 is used for driving the rotating support rod 433. The buffer member 46 is installed between the lifting rod 41 and the limiting plate.

[0047] The lifting member 45 includes a first electric push rod 451, a pushing seat 452, a pushing support rod 453 and a pushing shaft 454. The first electric push rod 451 is fixedly installed on the moving block 435, and the output end of the first electric push rod 451 is fixedly connected to the pushing seat 452. There are two pushing support rods 453. One ends of the two pushing support rods 453 are rotatably connected to the pushing seat 452 through a rotating shaft, and the other ends of the two pushing support rods 453 are rotatably connected to the pushing shaft 454. The pushing shaft 454 fixedly penetrates through the rotating support rod 433.

[0048] The buffer member 46 includes a buffer spring 461 and a connecting plate 462. The connecting plate 462 is fixedly sleeved on the top of one end of the lifting rod 41. The two ends of the buffer spring 461 are respectively fixedly connected to the connecting plate 462 and the limiting plate, and the buffer spring 461 is sleeved on the outside of the lifting rod 41;

[0049] On one side of the support platform 3 and at the bottom of the transfer plate 5, there is a transfer conveying mechanism 7. The transfer conveying mechanism 7 processes the agglomerated flour and then guides it to the vacuum discharge pipe 2.

[0050] Specific implementation process: When the staff places the opening of the bagged flour facing the feeding port 33. In this embodiment, the staff puts the first half of the bagged flour into the feeding port 33. At this time, the lifting rod 41 is located at the bottom of the bagged flour. Then, the staff only needs to hold both ends of the tail of the bagged flour. Subsequently, the two first electric push rods 451 operate. When the first electric push rod 451 operates, its output end pushes the rotating support rod 433 to rotate through the pushing support rod 453. The rotating support rod 433 rotates around its connection point with the fixed seat 434. When the rotating support rod 433 rotates, it drives the lifting rod 41 to move through the connecting support rod 432. Due to the limiting effect of the lifting rod 41 on the fixing plate 42, both ends of the lifting rod 41 are synchronously stressed and move upward. During the upward movement of the lifting rod 41, the bagged flour is lifted through the horizontal section of the lifting rod 41, and at the same time, the flour continuously falls into the feeding port 33 from the opening. During this process, although the negative pressure dust removal cover 31 is provided, there is still a lot of flour flying at the feeding port 33. Therefore, through this setting, it is avoided that the staff is too close to the feeding port 33. At the same time, by the reciprocating extension and retraction operation of the output ends of the two first electric push rods 451, when the bagged flour is almost half emptied, the staff can easily pour out the remaining flour in the bag;

[0051] On the other hand, with the arrangement of the lifting rod 41 in the present invention, after the staff pours a bag of flour into the feeding port 33, the lifting rod 41 moves along the feeding port 33 through the moving member 44, so as to evenly distribute the flour at the feeding port 33, the through hole 51 and on the screen 11, enabling the flour to quickly enter the feeding hopper 1 and finally enter the vacuum discharge pipe 2 from the feeding hopper 1;

[0052] Meanwhile, in this embodiment, the lifting rod 41 is provided. When there is agglomerated flour, in order to prevent large agglomerated flour, through the movement of the lifting rod 41, the large agglomerated flour on the screen 11 is initially broken up and dispersed, which is convenient for the transfer plate 5 to subsequently move the agglomerated flour.

[0053] Please refer to Figure 2 , a moving and adjusting mechanism 6 is provided on the support platform 3. When there is agglomerated flour at the through hole 51, the moving and adjusting mechanism 6 moves the agglomerated flour by adjusting the position of the transfer plate 5;

[0054] The moving and adjusting mechanism 6 includes a second electric push rod 61 and a matching block 62. The second electric push rod 61 is fixedly installed on the outside of the support platform 3, and the output end of the second electric push rod 61 is fixedly connected to the matching block 62. A moving port is provided on the support platform 3 corresponding to the position of the matching block 62. The matching block 62 slidably penetrates through the moving port, and the matching block 62 is fixedly connected to the transfer plate 5;

[0055] Specifically: after each bag of bagged flour is poured into the feeding hopper 1 from the feeding port 33, there is still a lot of agglomerated flour remaining on the screen 11. At this time, the second electric push rod 61 operates, and the transfer plate 5 is pushed through the matching block 62. Then the transfer plate 5 is pushed along the transfer and conveying mechanism 7 until the through hole 51 of the transfer plate 5 deviates from the screen 11. At the same time, the transfer plate 5 keeps the upper part of the screen 11 closed, and the through hole 51 of the transfer plate 5 moves to the processing material port 35. Then the transfer plate 5 pushes the agglomerated flour into the transfer and conveying mechanism 7;

[0056] As a supplementary explanation, in this embodiment, when the through hole 51 of the transfer plate 5 is in communication with the feeding port 33, the transfer plate 5 synchronously keeps the processing material port 35 closed to prevent the flour at the processing material port 35 from overflowing from the processing material port 35.

[0057] Please refer to Figures 8 to 12 , the transfer and conveying mechanism 7 includes a fixed hopper 71 and a movable hopper 72. The fixed hopper 71 is fixedly installed at the bottom of one end of the support platform 3, and a processing material port 35 is provided on the support platform 3 corresponding to the fixed hopper 71. The bottom of the fixed hopper 71 is communicated with a transfer pipe 73, and the other end of the transfer pipe 73 is communicated with the vacuum discharge pipe 2. An electromagnetic valve 74 is provided on the transfer pipe 73;

[0058] A connecting piece 8 is provided inside the fixed hopper 71 , and the connecting piece 8 is connected to the movable hopper 72 . The movable hopper 72 is provided with a plurality of discharge holes 721 .

[0059] The connecting member 8 includes a top rod 81, a bottom rod 82, a synchronous housing 83, a rotating motor 84 and a swinging member 85. Two top rods 81 and two bottom rods 82 are provided respectively. The two top rods 81 are fixedly installed at the top of the fixed hopper 71, and the two bottom rods 82 are fixedly installed inside the processing material port 35. Two connecting springs 86 are respectively sleeved on the outer sides of the top rod 81 and the bottom rod 82. Support blocks 87 are slidably connected to the two bottom rods 82, and the two sides of the support blocks 87 are in contact with the connecting springs 86.

[0060] A synchronous block 88 is slidably connected between the two push rods 81, and both sides of the synchronous block 88 are in contact with the connecting spring 86;

[0061] The synchronous housing 83 is fixedly installed between two support blocks 87, and the movable hopper 72 is rotatably connected to the top of the synchronous housing 83. The rotating motor 84 is installed inside the synchronous housing 83, and the output end of the rotating motor 84 is fixedly connected with a rotating shaft 89. The top of the rotating shaft 89 is rotatably connected to the synchronous block 88, and the swinging member 85 is installed between the rotating shaft 89 and the movable hopper 72.

[0062] The swinging member 85 includes a heating shell 851, a rotating block 852 and a heating block 853. The heating shell 851 is sleeved on the outside of the rotating shaft 89, and the heating shell 851 is fixedly connected to the movable hopper 72. The rotating block 852 is fixedly sleeved on the outside of the rotating shaft 89, and the heating block 853 is fixedly installed on the outside of the rotating block 852, and the heating block 853 and the rotating block 852 are both located inside the heating shell 851, that is, in this embodiment, the rotating shaft 89 is fixedly connected to the movable hopper 72 through the heating shell 851.

[0063] Two protective baffles 9 are installed at the processing material port 35, and the two protective baffles 9 are used to protect the connection spring 86 at the top rod 81. A side plate 91 is fixedly installed on the outside of the protective baffle 9, and a stirring rod 92 is installed at the bottom of the side plate 91. The stirring rod 92 is located inside the movable hopper 72;

[0064] Specific implementation process: when the transfer plate 5 guides the block-shaped flour into the movable hopper 72 from the processing port 35 through the through hole 51, and the transfer plate 5 closes the top of the processing port 35 again, the rotating motor 84 is operated, and when the rotating motor 84 is operated, the rotating shaft 89 drives the movable hopper 72 to rotate relative to the fixed hopper 71 through the heating shell 851;

[0065] At this time, on the one hand, when the movable hopper 72 rotates, a centrifugal force is generated to break the agglomerated flour inside it. At the same time, the two stirring rods 92 fixed relative to the movable hopper 72 break the lumpy soft flour in the movable hopper 72.

[0066] On the other hand, when the rotating shaft 89 rotates, the rotating block 852 drives the heating block 853 to rotate synchronously. Since the heating block 853 is located at a part of the outer side of the rotating block 852, due to the connection of the top rod 81 and the bottom rod 82, the rotating block 852 swings, further causing the movable hopper 72 to swing relative to the inside of the fixed hopper 71. At the same time, in the state where the heating block 853 is heating, the agglomerated flour is further heated and crushed, so that the powdered flour enters the fixed hopper 71 from the plurality of discharge holes 721 at the movable hopper 72. When there is a large amount of flour accumulated in the fixed hopper 71, the solenoid valve 74 is opened. Subsequently, the flour is poured into the vacuum discharge pipe 2 and finally discharged and fed from the vacuum discharge pipe 2.

[0067] Embodiment 2

[0068] Please refer to Figures 2 to 4 , Embodiment 2 is a further supplementary description of Embodiment 1. Specifically, the moving member 44 includes a moving lead screw 441, a synchronous gear 442, a gear chain 443 and a synchronous motor 444. There are two moving lead screws 441. One end of the two moving lead screws 441 penetrates through the support frame 3, and the moving lead screw 441 is rotatably connected to the support frame 3. The two moving blocks 435 are respectively threadedly sleeved on the outer sides of the two moving lead screws 441. There are two synchronous gears 442. The two synchronous gears 442 are respectively fixedly sleeved on one end of the two moving lead screws 441. The synchronous motor 444 is fixedly installed on the outer side of the support frame 3, and the output end of the synchronous motor 444 is fixedly connected to one of the synchronous gears 442.

[0069] Thus, when synchronously driving the two moving blocks 435, the synchronous motor 444 runs to further rotate one of the synchronous gears 442. When one of the synchronous gears 442 rotates, the two synchronous gears 442 are synchronously rotated through the gear chain 443. At this time, the moving lead screws 441 rotate synchronously and in the same direction, and then respectively provide synchronous driving forces for the two moving blocks 435. And under the limiting action of the feeding table surface 32 on the moving blocks 435, the two moving blocks 435 move along or away from the support frame 3.
