[0038] like Figure 2 and Figure 3 As shown, the conveying device 5 includes a conveyor belt 51 and a conveyor belt roller 52. The conveyor belt rollers 52 are arranged at both ends of the conveyor belt 51. The head end of the conveyor belt 51 is arranged below the transverse crank slider cutter 43, and the tail end of the conveyor belt 51 is connected to the inlet of the frying device 6.

[0039] like Figure 2 and Figure 3 As shown, the frying device 6 includes an oil pan 61, a tumbling frame 62, a scooping net 63, and a fried dough sticks discharge hopper 64.

[0040] like Figure 2As shown in FIG. 5 , the transmission device 7 includes a motor 71, the noodle feeding device 1 is connected to the motor 71 through a worm sprocket mechanism 72, the dividing device 4 is connected to the motor 71 through a cutting roller sprocket mechanism 73 and a cutting roller pulley mechanism 74, the powder sweeping device 2 is connected to the forming device 3 through a brush roller pulley mechanism 75, the forming device 3 is connected to the dividing device 4 through a roller roller pulley mechanism 76, the conveying device 5 is connected to the dividing device 4 through a conveying pulley mechanism 77, the frying device 6 is connected to the conveying device 5 through an oil pan pulley mechanism 78, and the tumbling frame 62 and the scoop net 63 are connected through a tumbling frame sprocket mechanism 79.

[0041] The working principle of this embodiment is as follows:

[0042] 1. Put the fermented dough into the dough feeding hopper 11, and press the irregular dough into two long strips through the screw conveyor 12. On the one hand, it is convenient to brush the surface of the dough with flour later. On the other hand, because the two worms rotate in opposite directions, the pressing and shaping of the dough can be enhanced to make it more uniform.

[0043] 2. The dough embryo is squeezed out from the two discharge ports of the dough embryo discharge channel 13 and naturally falls to the powder sweeping device 2. The raw powder stored in the raw powder funnel 21 is evenly applied to the outer surface of the dough embryo through the rotation of the brush roller 22, which can prevent the dough embryo from sticking in the subsequent device and reduce the surface humidity of the dough embryo, making the outer surface more crispy when fried;

[0044] 3. The dough with the flour is pressed into a single-layer thin dough by the rolling roller 31. The annular grooves at both ends of the rolling concave roller 311 and the annular protrusions at both ends of the rolling convex roller 322 cooperate with each other to limit the deformation of the dough during extrusion, so that the rolling effect can be achieved according to the predetermined rolling requirements.

[0045] 4. Two single-layer thin dough embryos are merged through the dough embryo discharging hopper 41 and fall into the cutting drum 42, and are stacked into double-layer dough embryos under the extrusion of the cutting drum 42. At the same time, the three circular cutters on the cutting drum 42 can divide a whole piece of dough embryo into four dough embryo strips with equal widths, and the four circular protrusions on the cutting drum 42 can make indentations in the middle of the dough embryo strips and make the double-layer dough embryos adhere to each other, simulating the step of squeezing by chopsticks in the actual manual production of fried dough sticks;

[0046] 5. The cut double-layer dough strips are cut by the horizontal crank slider cutter 43 during the falling process. At this time, the stopper 81 on the frame 8 can better cooperate with the cutter head of the cutter 431. At the same time, a knife groove 82 is provided on the side wall of the frame 8 to ensure that the cutter 431 does not deviate, thereby cutting the continuous dough strips into dough strips of predetermined length.

[0047] 6. The cut dough pieces of the fried dough sticks fall onto the conveyor belt 51 and are placed horizontally, and are transported to the next process by the conveyor belt 51. The operator can also directly take out the dough pieces of the fried dough sticks and store them for later use.

[0048] 7. After passing through the conveyor belt 51, the dough of the fried dough sticks will fall into the oil pan 61, and will be turned over and guided by the four rolling racks 62 in the oil pan 61. Finally, after being scooped out by the scoop net 63 and controlled by oil, the dough sticks will fall into the fried dough stick discharging hopper 64.

[0049] 8. The power source of this machine is only one motor 71. The motor 71 first transmits power to the cutting roller 42 in the dividing device 4 through the cutting roller sprocket mechanism 73 and the cutting roller pulley mechanism 74. The dividing device 4 transmits power to the two groups of rollers 31 of the forming device 3 and the two brush rollers 22 of the powder sweeping device 2 in sequence through the roller roller pulley mechanism 76 and the brush roller pulley mechanism 75 upward. The dividing device 4 transmits power to the horizontal crank slider cutter 43 and the conveying mechanism 5 in sequence through the crank slider pulley mechanism 433 and the conveying pulley mechanism 77 downward. Then the conveying mechanism 5 transmits power to the rolling frame 62 and the scoop net 63 through the oil pan pulley mechanism 78 and the rolling frame sprocket mechanism 79; because the transmission direction of the noodle entry device 1 is different from that of the motor 71, the worm sprocket mechanism 72 includes a group of bevel gears for changing the transmission direction of power, thereby transmitting the power to the screw conveyor 12 in the noodle entry device 1.
