[0019] This application discloses a dough cutting machine. (Refer to...) Figure 1 , Figure 2 and Figure 3The dough cutting machine includes a base plate 1, with one end being the feeding end and the other end being the discharging end. The feeding end is equipped with a hopper 2 for storing dough and a discharge pipe 3 for discharging strips of dough. The discharge pipe 3 is conical in shape. This tapered design generates gradually increasing pressure on the dough, helping to expel large air bubbles and making the dough structure denser. It also guides the dough to form stable, regularly shaped (usually circular or near-circular) continuous strips, providing a morphological basis for subsequent cutting. The feeding end is equipped with a useful... The conveying component 4 conveys the dough in the hopper 2 toward the discharge pipe 3. A fixed frame 5 is connected to the discharge pipe 3. A cutting cylinder 51 is connected to the fixed frame 5. A cutting blade 52 is connected to the end of the piston rod of the cutting cylinder 51. A slot 521 is opened on the cutting blade 52 for the strip-shaped dough to pass through. A first cutting surface 522 and a second cutting surface 523 are respectively provided at the bottom of the cutting blade 52 and the bottom of the slot 521. The first cutting surface 522 and the second cutting surface 523 of the cutting blade 52 can cut the strip-shaped dough back and forth. A discharge component 6 is provided at the discharge end.

[0020] The slot 521 on the cutting blade 52 for the strip of dough to pass through, and the first cutting surface 522 and the second cutting surface 523 respectively provided at the bottom of the cutting blade 52 and the bottom of the slot 521, constitute a unique "double-edged" cutting structure. During cutting, when the strip of dough is stably and uniformly discharged through the hopper 2, the conveying component 4 and the discharge pipe 3, the cutting cylinder 51 drives the cutting blade 52 to move up and down reciprocally. When the cutting blade 52 descends, the first cutting surface 522 performs a cutting operation on the strip of dough, and then the strip of dough passes through the slot 521 of the cutting blade 52. When the cutting blade 52 rises, the second cutting surface 523 at the bottom of the slot 521 performs the next cutting operation on the strip of dough, and then the strip of dough passes under the cutting blade 52. This repetition ensures the consistency of the length and volume of the cut dough.

[0021] Conveying assembly 4 includes a shock absorber 41, a support 42, a conveying pipe 43, a fixed bearing 44, a rotating shaft 45, a screw conveyor blade 46, and a rotating motor 47. The shock absorber 41 is connected to the base plate 1, the support 42 is connected to the shock absorber 41, and the conveying pipe 43 is connected to the support 42. The conveying pipe 43 is arranged along the length of the base plate 1, with one end being a sealed end and the other end being an open end. The open end of the conveying pipe 43 is connected to the discharge pipe 3, and the fixed bearing 44 is connected to the sealed end of the conveying pipe 43. The rotating shaft 45 is connected to the fixed bearing 44. The axis of the rotating shaft 45 is collinear with the axis of the conveying pipe 43. The spiral conveying blade 46 is set on the rotating shaft 45. The side wall of the spiral conveying blade 46 rotates and fits against the inner wall of the conveying pipe 43. The rotating motor 47 is mounted on the shock absorber 41. The output shaft of the rotating motor 47 is coaxially connected to the rotating shaft 45 through a coupling. The conveying pipe 43 is provided with a feed inlet located at one end of the conveying pipe 43 near the rotating motor 47. The hopper 2 is connected to the feed inlet.

[0022] The design of the conveying assembly 4 (the spiral conveying blade 46 rotates inside the conveying pipe 43) ensures that the conveying process of dough from hopper 2 to discharge pipe 3 is continuous, stable and uniform. The design of the spiral conveying blade 46 rotating and fitting against the inner wall of the conveying pipe 43 minimizes the residue and blockage of dough in the conveying pipe 43, and ensures that the strip dough extruded from the outlet of discharge pipe 3 has a continuous and uniform cross section and density.

[0023] A guide rod 524 is connected to the cutting blade 52. The guide rod 524 is set in the vertical direction. There is one guide rod 524 at each end of the cutting blade 52. The fixing frame 5 has a guide hole for the guide rod 524 to pass through.

[0024] A linear bearing 53 is connected to the fixed frame 5. The linear bearing 53 is located in the guide hole, and the guide rod 524 slides through the linear bearing 53.

[0025] By setting the guide rod 524 and the linear bearing 53, the movement trajectory of the cutting blade is strictly limited, so that it can only perform strictly vertical up-and-down reciprocating motion under the drive of the cutting cylinder 51. This eliminates the lateral swaying or tilting that the cutting blade 52 may produce during the cutting process, ensuring the flatness of the cutting surface and the accuracy of the cutting dimensions.

[0026] The discharge assembly 6 includes a fixed plate 61, a transmission roller 62, a transmission belt 63, and a drive motor 64. The fixed plate 61 is connected to the base plate 1 and is arranged in a direction perpendicular to the base plate 1. The fixed plate 61 is arranged along the length of the base plate 1 and is provided on opposite sides of the base plate 1. The transmission roller 62 is connected between the two fixed plates 61 and is provided at both ends of the fixed plate 61. The transmission belt 63 is tensioned and wound between the two transmission rollers 62. One end of the transmission belt 63 is located below the discharge pipe 3. The drive motor 64 is mounted on the fixed plate 61 and the output shaft of the drive motor 64 is coaxially connected to the roller shaft of the transmission roller 62 through a coupling.

[0027] The surface of the cutting blade 52 is coated with a nano-ceramic coating to prevent sticking.

[0028] The implementation principle of a dough cutting machine according to an embodiment of this application is as follows: During operation, dough is filled into hopper 2 and compacted by an external extrusion device. Then, the rotary motor 47 and drive motor 64 are started. The rotary motor 47 drives the rotary shaft 45 and the spiral conveyor blade 46 to rotate, which is used to convey the dough to the discharge pipe 3. The drive motor 64 drives the transmission roller 62 and the transmission belt 63 to rotate, which is used to convey the cut dough. When the strip-shaped dough at the outlet of the discharge pipe 3 is stably and uniformly discharged for a certain period of time, the cutting cylinder 51 pushes the cutting blade 52 down. The first cutting surface 522 performs a cutting operation on the strip-shaped dough. Then the strip-shaped dough passes through the slot 521 of the cutting blade 52. When the cutting blade 52 rises, the second cutting surface 523 at the bottom of the slot 521 performs the next cutting operation on the strip-shaped dough. Then the strip-shaped dough passes under the cutting blade 52. This process is repeated to ensure the consistency of the length and volume of the cut dough.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
