In various large restaurants or canteens, cutting vegetables often requires a lot of manpower and material resources, and also consumes a lot of time. There are also a small number of automatic food cutting equipment on the market. Existing automatic food cutting equipment, such as a multifunctional cutting machine disclosed in Chinese Patent Publication No. CN113386198A on September 14, 2021, includes a multifunctional cutting machine, including a bottom plate fixed to the bottom between the left guard plate and the right guard cover assembly, a food trough is fixedly connected to the top center of the bottom plate, a rear side plate is fixedly connected to the rear end between the left guard plate and the right guard cover assembly, and a motor drive box assembly is fixedly connected to the front end of the inner side of the left guard plate; a pusher assembly is fixedly connected to the outer side of the left guard plate, and a pushing mechanism corresponding to the food trough is fixedly connected to the output end of the pusher assembly; the rocker of the pusher assembly is pressed down, the spring contracts to retract the pushing mechanism, and the rocker of the pusher assembly is pushed up, and the spring rod will link the pushing mechanism, thereby pushing the food to move toward the knife disc. The above-mentioned existing automatic food cutting equipment has the following problems: 1. When the above-mentioned automatic food cutting equipment is working, the spring rod will extend horizontally and then retract into the body, resulting in the size of the entire automatic food cutting equipment becoming larger and occupying a larger area. 2. The structure of its pusher assembly is complicated. Referring to the power mechanism of a food cutting machine feeding device disclosed in Chinese Patent Announcement No. CN214238553U, it is necessary to manually rotate the rocker arm to start automatic feeding; 3. The above-mentioned existing automatic food cutting equipment is too simple in design, with low safety performance and no safety switch. It is easy for human hands to contact the knife and the pusher device, which is prone to accidents. 4. However, when the existing automatic food cutting equipment is in use, it is impossible to adjust the cutting mechanism in the fruit and vegetable cutting machine to cut fruits and vegetables of different thicknesses, or the cutting mechanism of the fruit and vegetable cutting machine needs to be disassembled as a whole when adjusting, which is cumbersome, time-consuming and labor-intensive. 5. Because there is a thickness difference between the blade of the cutting knife and the surface of the knife disc when the cutting knife is slicing vegetables, the blade of the cutting knife and the knife disc will intermittently contact the vegetables, so the push plate and the slider will be frustrated, the push plate and the vegetables will move back, the cutting will not be smooth, and there will be noise.

[0080] The slicing seam 64 is in an arc shape.

[0081] The controller 23 is provided with a forward button, a backward button, a reset button, and a switch button. When the vegetable cutter of the present invention is powered on and in standby mode, the user presses the reset button, and the push motor 42 drives the nut slider 44 to slide backward and return to the beginning of its stroke, so that the user can put vegetables into the feed slot again. When the vegetable cutter of the present invention is powered on and in standby mode, the user presses the forward button or the backward button, and the push motor 42 drives the nut slider 44 to move forward or backward and slide to the beginning or end of its stroke. The user can stop pressing at any time. After the user lets go, the push plate 46 stops sliding, thereby controlling the position of the push plate 46.

[0082] The working principle of the present invention is: When the vegetable cutter of the present invention is powered on and on standby, the user opens the feeding cover and then presses the back button, the pushing motor 42 drives the screw rod 43 to rotate in the opposite direction, the screw rod 43 rotates in the opposite direction to drive the nut slider 44 to slide backward, the nut slider 44 drives the pushing plate 46 to slide backward, the pushing spring 47 is compressed until the nut slider 44 touches the first micro switch 410, the first micro switch 410 disconnects the circuit of the pushing motor 42 and sends a signal to the controller 23, the pushing motor 42 stops, and then the user puts the vegetables into the feeding trough 45, and then cover the feeding cover, the fourth micro switch is triggered, and sends a signal to the controller 23, the user presses the switch button, the cutting motor 5 and the pushing motor 42 are started, the cutting motor 5 drives the cutting tool to rotate, the pushing motor 42 drives the screw rod 43 to rotate forward, the screw rod 43 rotates forward to drive the nut slider 44 to slide forward, the nut slider 44 no longer presses against the pushing plate 46, the nut slider 44 no longer blocks the pushing plate 46 from sliding, the nut slider 44 keeps sliding forward until the second micro switch 49 is triggered, and the fourth micro switch 49 is turned on. The second micro switch 49 disconnects the circuit of the push motor 42 and sends a signal to the controller 23, and the push motor 42 stops. At the same time, the push spring 47 pushes the push plate 46 to slide forward. The push spring 47 extends, and the push plate 46 pushes the vegetables in the feed trough 45 to slide forward. Since the cutting tool blocks the vegetables in the feed trough, the push plate 46 cannot slide forward quickly, and the vegetables in the feed trough 45 are gradually pushed into the cutting box 3. The cutting tool cuts the vegetables into slices, and the sliced ​​vegetables fall out of the cutting box 3 from the drop port. When the push plate 46 moves to the front end of the feed trough 45, the push plate 46 stops moving forward. At this time, all the vegetables in the feed trough are cut by the cutting tool. The push plate triggers the third microswitch 411, and the third microswitch 411 disconnects the circuit of the cutting motor and sends a signal to the controller 23. The cutting motor stops, and the controller 23 sends a signal to the push motor 42 at the same time. The push motor 42 drives the screw rod 43 to rotate in the opposite direction, and the nut slider 44 drives the push plate 46 to slide backward, making it convenient for the user to put vegetables into the feed trough again.

[0083] When the user wants to replace the cutting tool, he can rotate the locking knob, then open the shell cover 31, then unscrew the locking bolt 66, and then remove the slicing tool, then install the dicing tool 8 or the shredding tool 7 on the motor shaft of the cutting motor 5, re-tighten the locking bolt 66, fix the dicing tool 8 or the shredding tool 7, and then close the shell cover 31. The fifth microswitch 37 is triggered, and the fifth microswitch connects the circuit of the cutting motor 5 and sends a signal to the controller 23.

[0084] When the user wants to change and adjust the slice thickness of the cutting tool, he can rotate the locking knob to open the shell cover 31, then loosen the locking bolt 66, and then rotate the adjusting nut 65. The adjusting nut 65 rotates to drive the external threaded barrel 68, the movable knife disc 61, and the movable blade 62 to move forward or backward, while the fixed blade 63 remains in place, thereby changing the size of the slicing gap 64 between the movable blade 62 and the fixed blade 63, thereby adjusting the slice thickness.
