[0027] In combination with Figures 6-7 , the use mode of the steamed bun blank cutting mechanism is as follows: (1) Figure 6The part structure schematic view of the steamed bun blank forming device where the steamed bun blank cutting mechanism is located, the steamed bun blank cutting mechanism is a component part of a whole steamed bun machine, the conveying belt 1-2 below the steamed bun blank forming device is used for conveying the dough column for making steamed bun blank forward, the support plate 1-1 at the bottom of the conveying belt 1-2 is driven by the driving mechanism of the steamed bun machine to move up and down, when the support plate 1-1 moves upward, the conveying belt 1-2 and the dough column above it are lifted up, so that the dough column is in contact with each shaping component of the steamed bun blank forming device, and finally the dough column forms a steamed bun blank.(2) When the dough column is conveyed to the position where the steamed bun blank cutting mechanism is located, the dough column has been shaped into the initial steamed bun blank shape by the plurality of die blocks, the two pairs of clamping rollers 500 in front, and the adjacent steamed bun blanks are initially cut into thin dough strips by the vertical extrusion block 600 and the steamed bun blank initial cutting clamp hand 100, at this time, the adjacent steamed bun blanks conveyed by the conveying belt are still connected by the dough strips, since the conveying belt is lifted up, the dough strips are in contact with the cutting edge of the pinch knife plate 31 in the right cutting knife assembly 3 of the steamed bun blank cutting mechanism, so as to cut the dough strips, at the same time, the two cutting knife assemblies 3 in front and behind of the steamed bun blank cutting mechanism are clamped in front and behind under the driving of the driving frame 2, so as to further break the cut dough strips, and the two cutting knife assemblies 3 clamped in front and behind can also shape the two sides of the steamed bun blank after cutting, and the die block 41 shapes the top surface of the steamed bun blank.

[0028] The effect of the steamed bun blank cutting mechanism is as follows: since the inner side of the pinch knife plate in the steamed bun blank cutting mechanism is curved outward into an arc shape, the steamed bun blank after cutting can be shaped while the dough strips connected between the steamed bun blanks are cut; in addition, since the cutting mode of the steamed bun blank cutting mechanism is to cut the dough strips by the cutting edge of the cutting knife while the two cutting knife assemblies 3 are clamped in front and behind under the driving of the driving frame 2, the dough strips can be pulled to the side of the cutting knife when being cut, compared with simple cutting, the cutting and pulling mode makes the dough strips break more completely.

A rotating support shaft 24 is further arranged on the first cross arm 21, which mainly plays a supporting role, a rotatable connecting rod frame 25 is arranged on the rotating support shaft 24, the connecting rod frame 25 is installed on the rotating support shaft 24 through a bearing, so that the connecting rod frame 25 can rotate, a vertical shaft 231 is arranged on each side of the second cross arm 23, the connecting rod frame 25 has a connecting rod part 251 on each side, an axle hole is arranged at the end of the connecting rod part 251, so that the end of the connecting rod part 251 is rotatably connected with the vertical shaft 231, the driving frame 2 further includes a swing rod 26 for driving the connecting rod frame 25 to swing, a roller 261 is arranged on the upper side of the end of the swing rod 26, the swing rod 26 is tightly connected between the connecting rod frame 25, and the swing rod 26 can drive the connecting rod frame 25 to swing when the swing rod 26 swings.

[0034] The working mode of the driving frame 2 of the steamed bun blank cutting mechanism is as follows: Figure 6 As shown, Figure 6 is a partial structure diagram of the steamed bun blank forming device where the steamed bun blank cutting mechanism is located, Figure 6 The steamed bun blank forming device in the figure is provided with a first longitudinal rod 401, a second longitudinal rod 402 and a third longitudinal rod 403, the first cross arm 21 in the driving frame 2 of the steamed bun blank cutting mechanism is installed on the third longitudinal rod 403, the third longitudinal rod 403 is a fixed rod, the first longitudinal rod 401 and the second longitudinal rod 402 can be driven by the driving mechanism of the steamed bun blank forming device to move close to each other, when the second longitudinal rod 402 moves, the roller 261 at the end of the swing rod 26 is driven to swing, the swing rod 26 is driven to swing, and under the action of the connecting rod frame 25, the two cutter assemblies 3 can be clamped in front of each other, when the first longitudinal rod 401 and the second longitudinal rod 402 are driven by the driving mechanism of the steamed bun blank forming device to move away from each other, the two cutter assemblies 3 are reset to move away from each other under the action of the reset spring between the two second cross arms 23 on the first guide rod 22.

[0035] Further, in another embodiment, as Figure 1 and Figure 4As shown, the die holder of the steamed bun blank cutting mechanism includes a second guide rod 42 movably arranged at one end outside the first horizontal arm 21, the second guide rod 42 is arranged in parallel with two second guide rods, a hole corresponding to the second guide rod 42 is arranged on the first horizontal arm 21, an end cover connected with the top of the first guide rod is arranged on the top of the first horizontal arm 21, the die block 41 is arranged at the bottom of the second guide rod 42, and the second spring 43 is sleeved on the second guide rod 42 and clamped between the die block 41 and the bottom surface of the first horizontal arm 21.

[0036] When the steamed bun blank on the conveyor belt lifted by the support plate at the bottom of the steamed bun machine contacts the bottom surface of the die block 41, the steamed bun blank can lift the die block 41 upward, the die block 41 moves upward together with the second guide rod 42, and the second spring 43 is compressed. After the steamed bun blank cutting mechanism completes the action of cutting the steamed bun blank, the conveyor belt lifted by the support plate at the bottom is lowered, the die block 41 is no longer subjected to upward resistance, and under the elastic action of the second spring 43, the die block 41 moves downward to return to the original position. Because the die block 41 can stretch up and down when subjected to force, the steamed bun blanks on the conveyor belt lifted by the support plate at the bottom are in soft contact with the die block 41, the die block 41 can adaptively shape the top surface of the steamed bun blank, avoid the steamed bun blank being flattened, and the travel of the conveyor belt moving up and down is more free.
