Blanking basic principle:

cereal is added into blanking hopper 1 by upper reaches machinery, falls into in box 4 behind blanking hopper 1, material roller 23 in box 4 is a plurality of feed bins 26 with its inside partition, first motor 5 is connected with the roller of material roller 23 through the gearbox, drives its rotation, and when feed bin 26 and the pan feeding mouth intercommunication at box 4 top, the material falls into feed bin 26, and after this feed bin 26 falls full of cereal, will not the blanking again, until material roller 23 rotates the back, new feed bin 26 and pan feeding mouth 4 intercommunication continue the blanking.

When the full grain bin 26 is rotated to communicate with the discharge opening, the grain falls onto the conveyor belt 3. Due to the same volume of the storage bin 26, the rotating speed of the first motor 5 is uniform, and the materials can be uniformly divided into multiple parts and conveyed by the conveying belt 3.

The function of the flap 6:

the turning plate 6 is used for changing the grain blanking mode, grains firstly fall onto the turning plate 6 and then fall onto the conveying belt 3 from the turning plate 6. The main purpose of the utility model is to change the grain blanking time.

Because the change trend of the communicated sectional areas of the bin 26 and the discharge port is increased and then decreased, grains can all fall onto the conveying belt in the process of increasing castings in the production process, the blanking speed is gradually increased until the blanking is completely finished, the grains which are not on the conveying belt are all in a conical structure and are not easy to gather together, and meanwhile, the conveying speed of the conveying belt 3 is not easy to control.

Baffle 6 can make cereal fall its top surface earlier, then opens baffle 6 fast, accomplishes the blanking fast, and the cereal can be piled up and put things in good order on the conveyer belt, makes things convenient for the processing of downstream processing equipment, and the blanking time is short simultaneously, and the regular speed that also helps adjusting conveyer belt 3 of blanking.

The opening and closing principle of the turning plate 6 is as follows:

the turning plates 6 are rotatably connected with the box body 4 through the main shaft 15, the turning plates 6 on the front side and the rear side of the main shaft 15 form a lever, under the condition of no external force, one side of each turning plate 6, which is positioned at the discharge port, can incline downwards due to gravity, the two turning plates 6 can integrally form an open state, and grains on the turning plates 6 fall onto the conveying belt 3 under the state.

When the other side of the push rod 8 is rotatably connected with the other side of the turning plate 6 through the auxiliary shaft 22 and the other side of the turning plate 6 is pressed down, the two turning plates 6 are integrally closed based on the lever tilting one side of the turning plate 6. In this condition the flap 6 will catch the grain falling above.

The driving principle of the flap 6 is as follows:

the cam 7 is connected with a roll shaft connecting shaft of the material roller 23 through a gear box 24, when the first motor 5 drives the roll shaft of the material roller 23 to rotate, the cam 7 rotates together through the transmission of the gear box 24, and in the rotating process of the cam 7, because the pinch roller 17 on one side of the push rod 8 is abutted against the edge of the cam 7, the push rod 8 is pushed to move along the vertical direction under the limit of the guide piece 19, so that the driving effect of opening and closing the turning plate 6 is achieved.

The adjusting principle of the flap 6 is as follows:

in order to achieve the beneficial effect of gathering and blanking, the plate 6 needs to be ensured to be closed all the time when receiving material, and after receiving material, the blanking and closing are completed rapidly before the next receiving material starts.

When the depression of the cam 7 is in contact with the pressing wheel 17, the push rod 8 is not pressed down by the cam 7, the turning plate 6 is opened to blank materials based on the turning plate opening and closing principle, when the pressing wheel 17 is in contact with other positions on the edge of the cam 7, the diameter of the cam 7 is increased, the push rod 8 is pressed down by the pressing wheel 17, the turning plate is closed based on the turning plate opening and closing principle, and the opening time of the turning plate 6 in one rotation period of the cam 7 is adjusted by adjusting the included angle between the two ends of the depression of the cam 7 and the wheel center.

The gear box 24 can adjust the rotation speed ratio between the roller shaft of the material roller 23 and the cam 7, so that when the material roller 23 rotates for one circle, the number of rotating circles of the cam 7 is equal to that of the bins 26, that is, the turning plate 6 can be opened and closed every time the bins 26 are blanked.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
