Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The utility model provides Figures 1-11 The illustrated rice noodle cutting machine comprises a frame 1 with a central cavity, a feeding mechanism 2 disposed within the cavity, and a combing mechanism 3, a cutting mechanism 4, a positioning grating assembly 5, and a screening and guiding mechanism 7 sequentially arranged along the conveying direction of the feeding mechanism 2. A controller for operating the cutting machine is provided on the frame 1.

[0045] The screening and guiding mechanism 7 includes a guide frame 71 connected to both sides of the discharge end of the frame 1, and a scraper plate 75 installed in the through cavity. Two rollers 73 are rotatably installed between the two guide frames 71, and a conveyor belt 72 is connected between the two rollers 73. A number of evenly distributed screening holes are opened on the conveyor belt 72. A third motor 76 is fixed to one side of one of the guide frames 71, and one end of one of the rollers 73 is connected to the main shaft of the third motor 76. The scraper plate 75 is on the unloading side of the feeding mechanism 2, and the top end of the scraper plate 75 is curved to form a shoveling part 74 that cooperates with the feeding mechanism 2. The height of the conveyor belt 72 is lower than the height of the shoveling part 74.

[0046] Specifically, the feeding mechanism 2 includes two conveying rollers 22 rotatably installed in the through cavity, and a first motor 23 fixed on one side of the frame 1. A conveyor belt 21 is connected between the two conveying rollers 22. The first motor 23 is used to drive one of the conveying rollers 22 to rotate, and the shoveling part 74 is attached to the upper surface of the conveyor belt 21.

[0047] Specifically, the combing mechanism 3 includes a combing frame 31 mounted on the frame 1, a combing plate 32 is provided inside the combing frame 31, and a first adjusting screw 33 is screwed on the combing frame 31, and the bottom end of the first adjusting screw 33 is rotatably connected to the top of the combing plate 32, and the bottom of the combing plate 32 is provided with a plurality of arc-shaped material troughs distributed at equal intervals along its length direction.

[0048] Specifically, the cutting mechanism 4 includes a mounting frame 41 mounted on the frame 1, a lifting plate 43 is provided inside the mounting frame 41, and an electric push rod 42 is installed on the top of the mounting frame 41, the telescopic end of the electric push rod 42 is connected to the top of the lifting plate 43, and a cutting plate 44 is installed at the bottom of the lifting plate 43.

At this time, the external receiving box can be placed on the ground, and then the fragments are discharged into the external receiving box through the discharge slot 94 under the guiding action of the guide plate 93, thereby realizing the collection of the fragments and facilitating the centralized processing of the fragments.

[0054] At the same time, in this embodiment, Figures 1-6As shown, the frame 1 is also provided with an adjustment component 6 for moving and adjusting the positioning grating assembly 5, and the adjustment component 6 includes a mobile frame 61 that is slidably sleeved on the outside of the frame 1, and two fixed plates 62 fixed to the bottom of the frame 1, a rotatable screw rod 63 is installed between the two fixed plates 62, and a second motor 64 that drives the screw rod 63 to rotate is fixed to one side of one of the fixed plates 62, and the bottom of the mobile frame 61 forms a connecting block that is screwed to the screw rod 63 by a thread, and the infrared transmitter 51 and the receiver 52 are respectively installed on the opposite sides of the top of the mobile frame 61.

[0055] During the rice noodle cutting process, the positioning grating assembly 5 can be adjusted according to the requirements of the rice noodle cutting length, and the specific adjustment steps are as follows:

[0056] The second motor 64 drives the screw rod 63 to rotate, so that the screw rod 63 drives the movable frame 61 to move along the outside of the frame 1 through the connecting block. At this time, the movable frame 61 drives the infrared transmitter 51 and the receiver 52 to move synchronously, so that the positioning grating assembly 5 is away from or close to the cutting plate 44 to adjust the cutting length of the rice noodle, so that the cutting machine can meet the requirements of different cutting lengths, which is conducive to the fixed-length cutting of the rice noodle and improves the practicality of the cutting machine.

[0061] The rotating rod 82 is rotated by adjusting the disk 85, so that the rotating rod 82 drives the main gear 83 to rotate, and then the main gear 83 drives the guide rack 71 to rotate through the sub-gear 84 engaged therewith, so that the guide rack 71 drives the conveyor belt 72 to rotate, so as to adjust the conveyor belt 72 to the required guiding angle, thereby realizing the adjustment of the guiding angle, which is beneficial for guiding the cut rice noodles at different angles to facilitate the discharge of the cutting machine, and then the second adjusting screw 89 is rotated, so that the second adjusting screw 89 drives the locking block 86 to move until the locking teeth on one side of the locking block 86 engage with the convex teeth on the outer wall of the adjusting disk 85, thereby locking the rotating rod 82 to a limit, so that the conveyor belt 72 remains fixed after adjustment, and ensures stable guiding of the cut rice noodles.
