Description

Technical Field

[0001] This utility model relates to the technical field of kitchen equipment, and in particular to a fully automatic vegetable cutter. Background Technology

[0002] Traditional food processing relies on manual cutting of vegetables. In large restaurants and canteens, this often requires significant manpower, resources, and time. While some automated food cutting equipment exists on the market, a notable example is the multi-functional cutting machine disclosed in Chinese Patent Publication No. CN113386198A on September 14, 2021. This machine includes a base plate fixed between a left guard plate and a right guard plate assembly. A food trough is fixedly connected to the center of the top of the base plate. A rear side plate is fixedly connected to the rear end of the left and right guard plate assemblies. 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. Pressing down the pusher assembly's rocker arm retracts the spring, pulling the pushing mechanism back. Pushing up the pusher assembly's rocker arm activates the spring, pushing the food towards the cutting disc. The existing automatic food cutting equipment has the following problems: 1. When the equipment is working, the spring rod extends horizontally and then retracts into the machine body, increasing the overall size and footprint of the equipment. 2. The pusher assembly has a complex structure. Referring to the power mechanism of the feeding device of a food cutting machine disclosed in Chinese Patent Publication No. CN214238553U, manual rotation of the rocker arm is required to activate automatic feeding. 3. The existing automatic food cutting equipment is too simple in design, has low safety performance, lacks safety switches, and allows easy contact with the blades and pusher components, increasing the risk of accidents. 4. However, existing automatic food cutting equipment cannot adjust the cutting mechanism within the fruit and vegetable cutter to cut fruits and vegetables to different thicknesses, or adjustment requires disassembling the entire cutting mechanism, which is cumbersome, time-consuming, and labor-intensive. 5. When the vegetable slicing knife is slicing vegetables, there is a thickness difference between the blade and the surface of the cutting disc. The blade and the cutting disc will make intermittent contact with the vegetables. Therefore, the push plate and the slider will jerk. The push plate and the vegetables will move backward, making the cutting uneven and noisy. Utility Model Content

[0003] The purpose of this invention is to provide a fully automatic vegetable cutter that is compact in structure, highly automated, and efficient in cutting vegetables.

[0004] The purpose of this utility model is achieved as follows:

[0005] A fully automatic vegetable cutter is characterized by comprising a main unit housing and a cutting box, the cutting box being fixedly connected to the front of the main unit housing; the main unit housing is equipped with a feeding trough, a cutting motor, and an automatic feeding mechanism; and the main unit housing has a vegetable dispensing opening corresponding to the feeding trough.

[0006] The cutting box contains a cutting blade that rotates around a horizontal axis. The front end of the feeding trough is connected to the inner cavity of the cutting box, and the bottom of the cutting box has a discharge port. The cutting motor drives the cutting blade to rotate and cut vegetables.

[0007] The automatic feeding mechanism includes a feeding motor, a lead screw, a nut slider, a feeding plate, a first guide shaft, and a feeding spring. The feeding motor drives the lead screw to rotate. The lead screw and the first guide shaft are horizontally mounted inside the main housing. The nut slider is horizontally slidable inside the main housing and threadedly connected to the lead screw. The feeding plate is horizontally slidable on the first guide shaft and slides horizontally within the feed groove. One end of the feeding spring abuts against the feeding plate, and the other end abuts against the main housing. The nut slider and the feeding plate abut against each other back and forth. When the feeding motor drives the lead screw to rotate in the reverse direction, the reverse rotation of the lead screw causes the nut slider to slide backward, which in turn causes the feeding plate to slide backward, compressing the feeding spring. When the feeding motor drives the lead screw to rotate in the forward direction, the forward rotation of the lead screw causes the nut slider to slide forward. The nut slider no longer presses against the feeding plate and no longer obstructs the sliding of the feeding plate. The feeding spring returns to its elastic deformation, pushing the feeding plate forward, and the feeding plate pushes the material forward. This fully automatic vegetable cutter utilizes a pusher spring and a pusher plate to automatically push the material forward. It also uses a pusher motor and a nut slider to drive the pusher plate backward. Furthermore, it utilizes a cutting motor and a cutting blade to achieve automatic cutting. Compared with existing technologies, this invention has a high degree of automation, high cutting efficiency, small size, compact structure, and small volume.

[0024] The fixed housing is equipped with a fifth micro switch, and the housing cover is equipped with a top post for triggering the fifth micro switch.

[0025] The cutting knife includes a movable cutting disc, a fixed cutting disc, movable blades, fixed blades, an adjusting nut, a locking bolt, and an external threaded cylinder. The movable cutting disc and the fixed cutting disc are coaxially mounted together. The movable blades and the fixed blades are respectively located on the rear surfaces of the movable cutting disc and the fixed cutting disc. The external threaded cylinder is located at the center of the movable cutting disc. The central bushing of the fixed cutting disc passes through the external threaded cylinder. The adjusting nut is threadedly connected to the external threaded cylinder. The locking bolt is movably mounted on the adjusting nut, passes through the adjusting nut, and extends into the central bushing of the fixed cutting disc.

[0056] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0057] Example 1, as Figures 1 to 16 As shown, a fully automatic vegetable cutter includes a main unit box 2 and a cutting box 3. The cutting box 3 is fixedly connected to the front of the main unit box 2. The main unit box 2 is provided with a feeding trough 45, a cutting motor 5 and an automatic pushing mechanism 4. The main unit box 2 is provided with a vegetable feeding port 21 corresponding to the feeding trough 45.

[0058] The cutting box is equipped with a cutting blade 6 that rotates around a horizontal axis. The front end of the feeding trough 45 is connected to the inner cavity of the cutting box 3. The bottom of the cutting box 3 is equipped with a discharge port 33. The cutting motor 5 drives the cutting blade 6 to rotate and cut vegetables.

[0059] The main unit 2 includes a chassis and a support frame 40 located inside the main unit 2.

[0060] The automatic feeding mechanism 4 includes a feeding motor 42, a lead screw 43, a nut slider 44, a feeding plate 46, a first guide shaft 48, and a feeding spring 47. The feeding motor 42 is mounted on a support frame and drives the lead screw 43 to rotate. The lead screw 43 and the first guide shaft 48 are horizontally mounted on a support frame 40 inside the main unit housing 2. The nut slider 44 is horizontally slidably mounted on the support frame 40 inside the main unit housing 2 and is threadedly connected to the lead screw 43. The feeding plate 46 is horizontally slidably mounted on the first guide shaft 48 and slides horizontally within the feed groove 45. The nut slider 44 and the feeding plate 46 abut against each other. One end of the feeding spring 47 abuts against the feeding plate 46, and the other end of the feeding spring 47 abuts against the support frame 40. When the feeding motor 42 drives the lead screw 43 to rotate, the rotation of the lead screw 43 causes the nut slider 44 to slide backward, which in turn causes the feeding plate 46 to slide backward, and the feeding spring 47 is compressed. When the pusher motor drives the lead screw to rotate in the forward direction, the forward rotation of the lead screw drives the nut slider to slide forward. The nut slider no longer pushes against the pusher plate 46, and the nut slider no longer blocks the sliding of the pusher plate 46. The pusher spring 47 restores its elastic deformation and pushes the pusher plate 46 forward, and the pusher plate 46 pushes the material forward.

[0061] This is a more specific technical solution of the present invention.

[0062] The push spring 47 is sleeved on the first guide shaft 48.

[0063] A second guide shaft 416 is horizontally arranged on the support frame 40, and a nut slider 44 is horizontally slidably arranged on the second guide shaft 416. The first guide shaft, the lead screw, and the second guide shaft 416 are arranged side by side, and the nut slider 44 is located on one side of the pusher plate. Therefore, the present invention has a compact structure and small size.

[0064] The nut slider 44 has a first micro switch 410 and a second micro switch 49 at the beginning and end of its sliding stroke, respectively. When the nut slider 44 touches the first micro switch 410 and the second micro switch 49, the first micro switch 410 and the second micro switch 49 will be triggered, the first micro switch 410 or the second micro switch 49 will disconnect the circuit of the pusher motor and send a signal to the controller 23, and the pusher motor will stop working.

[0065] A third micro switch 411 is provided at the end of the sliding stroke of the pusher plate 46. When the pusher plate 46 touches the third micro switch 411, the third micro switch 411 will be triggered, the third micro switch 411 will disconnect the circuit of the cutting motor and send a signal to the controller 23.

[0066] The shape of the pusher plate 46 is adapted to the shape of the feed trough 45.

[0067] The pusher plate 46 is provided with a first hook block 413, and the nut slider 44 is provided with a second hook block 414 corresponding to the first hook block 413. The second hook block 414 is located in front of the first hook block 413, and the first hook block 413 and the second hook block 414 abut against each other.

[0068] The controller 23 is located on the top of the main unit 2.

[0069] The bottom of the main unit 2 is equipped with support feet 1.

[0070] The top surface of the main unit 2 is provided with a vegetable inlet 21 corresponding to the feeding trough 45.

[0071] The top surface of the main unit 2 is provided with a feeding cover 22 for opening or closing the vegetable feeding port 21.

[0072] The feeding cover is rotatably connected to the main unit 2, and a fourth micro switch is provided at the corresponding position of the feeding cover on the main unit 2. When the feeding cover closes the vegetable inlet 21, the feeding cover triggers the fourth micro switch 419, which connects the circuit of the cutting motor. When the feeding cover rotates open, the feeding cover does not trigger the fourth micro switch 419, which disconnects the circuit of the cutting motor and sends a signal to the controller 23, stopping the cutting motor from working.

[0073] The cutting box 3 includes a fixed shell 32 and a cover 31. The rear side of the fixed shell 32 is connected to the front end of the feed trough 45. The cutting blade 6 is rotatably disposed inside the fixed shell 32. The cover 31 is rotatably connected to the front side of the fixed shell 32. The cover 31 can be opened and closed on the fixed shell 32.

[0074] The fixed shell 32 is provided with a locking knob 38 for locking or unlocking the shell cover 31, and the shell cover 31 is provided with a locking pin 35. The locking knob 38 is provided with a locking groove 34 corresponding to the position of the locking pin 35. One end of the locking groove 34 is provided with an inlet, and the locking pin 35 slides into the locking groove 34 through the inlet.

[0075] A fifth micro switch 37 is provided on the fixed housing 32, and a top post 36 for triggering the fifth micro switch 37 is provided on the housing cover. When the housing cover is closed, the top post 36 on the housing cover triggers the fifth micro switch, which connects the circuit of the cutting motor 5. When the housing cover is opened, the fifth micro switch 37 is not triggered, the fifth micro switch 37 disconnects the circuit of the cutting motor 5, and sends a signal to the controller 23, causing the cutting motor to stop working.

[0076] The vegetable cutting knife 6 includes a movable blade disc 61, a fixed blade disc 67, a movable blade 62, a fixed blade 63, an adjusting nut 65, a locking bolt 66, and an external threaded cylinder 68. This utility model's vegetable cutting knife is a slicing knife; however, it can also be a shredder 7 or a dicer 8. The movable blade disc 61 and the fixed blade disc 67 are coaxially mounted together. The movable blade 62 and the fixed blade 63 are respectively located on the rear surface of the movable blade disc 61 and the rear surface of the fixed blade disc 67. The threaded cylinder 68 is located at the center of the movable cutter head 61. The central bushing 610 of the fixed cutter head 67 passes through the threaded cylinder 68. The adjusting nut 65 is threadedly connected to the threaded cylinder 68. The locking bolt 66 is movably mounted on the adjusting nut 65. The locking bolt 66 passes through the adjusting nut 65 and extends into the central bushing 610 of the fixed cutter head 67. There is a gap between the movable blade 62 and the fixed blade 63 to form a slicing slit 64. The movable cutter head 61 is axially movable on the fixed cutter head 67.

[0077] The center hole of the movable cutter head 61 is fitted onto the outer side of the external threaded cylinder 68 and is interference-fitted with the external threaded cylinder 68.

[0078] The adjusting nut 65 includes an inner ring 613 and an outer ring 612 that are connected to each other and disposed inside and outside. The inner sidewall of the outer ring 612 is provided with an internal thread. The outer ring 612 is threadedly connected to the external threaded cylinder 68. The end face of the inner ring 613 abuts against the end face of the central bushing 610. The locking bolt 66 passes through the inner ring 613 and abuts against the end face of the central bushing 610.

[0079] The inner end face of the locking bolt 66 is provided with a locking screw 69 for threaded connection with the screw hole 52 on the motor shaft 51, and the inner end face of the locking bolt 66 abuts against the end face of the central bushing 610. The locking bolt fixes the adjusting nut 65, the movable cutter head 61, and the fixed cutter head 67 to the motor shaft 51.

[0080] The adjusting nut 65 is a plastic nut, which is easily deformed. Therefore, when the adjusting nut 65 is assembled with the locking bolt, the adjusting nut 65 can overcome the obstruction of the first anti-loosening buckle 614 and be forcibly pressed into the inner ring.

[0081] The inner wall of the inner ring of the adjusting nut 65 is provided with a first anti-loosening buckle 614, and the outer wall of the locking bolt 66 is provided with a second anti-loosening buckle 613 corresponding to the first anti-loosening buckle 614. The first anti-loosening buckle 614 and the second anti-loosening buckle 613 are in anti-loosening engagement. This structure can effectively prevent the locking bolt 66 from being lost.

[0082] The inner wall of the external threaded cylinder 68 is provided with a limiting step 615, and the outer wall of the central bushing 610 is provided with a limiting protrusion ring 611. The limiting protrusion ring 611 cooperates with the limiting step 615. The limiting protrusion ring is used to block the adjusting nut and the movable cutter head from moving outward, thereby limiting the size of the cutting slit adjusted by the adjusting nut 65.

[0083] The end face of the inner ring 613 abuts against the limiting protrusion 611.

[0084] The suture 64 of the slice is arc-shaped.

[0085] The controller 23 is equipped with a forward button, a reverse button, a reset button, and a power button. When the vegetable cutter is powered on and in standby mode, the user can press the reset button, causing the pusher motor 42 to drive the nut slider 44 to slide backward, returning to the beginning of its stroke, making it convenient for the user to put vegetables into the feeding trough again. When the vegetable cutter is powered on and in standby mode, the user can press the forward or reverse button, causing the pusher motor 42 to drive the nut slider 44 forward or backward, sliding to the beginning or end of its stroke. The user can stop pressing the button at any time. After the user releases the button, the pusher plate 46 stops sliding, thereby controlling the position of the pusher plate 46.

[0086] The working principle of this utility model is as follows:

[0087] When the vegetable cutter of this utility model is powered on and in standby mode, the user opens the feeding cover and then presses the reverse button. The pusher motor 42 drives the lead screw 43 to rotate in the opposite direction. The reverse rotation of the lead screw 43 drives the nut slider 44 to slide backward. The nut slider 44 drives the pusher plate 46 to slide backward, and the pusher 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 pusher motor 42 and sends a signal to the controller 23, stopping the pusher motor 42. Then, the user puts the vegetables into the feeder. The material is placed in the feed trough 45, and then the feeding cover is closed. The fourth micro switch is triggered and sends a signal to the controller 23. The user presses the switch button, and the cutting motor 5 and the pushing motor 42 start. The cutting motor 5 drives the cutting blade to rotate, and the pushing motor 42 drives the lead screw 43 to rotate forward. The forward rotation of the lead screw 43 drives the nut slider 44 to slide forward. The nut slider 44 no longer pushes against the pushing plate 46, and the nut slider 44 no longer obstructs the sliding of the pushing plate 46. The nut slider 44 continues to slide forward until the second micro switch 49 is triggered. The second micro switch 49 disconnects the circuit of the pusher motor 42 and sends a signal to the controller 23, stopping the pusher motor 42. At the same time, the pusher spring 47 pushes the pusher plate 46 forward, extending the pusher spring 47. The pusher plate 46 pushes the vegetables in the feed trough 45 forward. Because the cutting blade blocks the vegetables in the feed trough, the pusher plate 46 cannot slide forward quickly. The vegetables in the feed trough 45 are gradually pushed into the cutting box 3. The cutting blade cuts the vegetables into slices, and the sliced ​​vegetables fall out of the cutting box 3 from the discharge port. When the pusher plate 46 moves to the front end of the feeding trough 45, the pusher plate 46 stops moving forward. At this time, the vegetables in the feeding trough have been cut by the cutting blade. The pusher plate triggers the third micro switch 411, which disconnects the circuit of the cutting motor and sends a signal to the controller 23. The cutting motor stops. The controller 23 sends a signal to the pusher motor 42 at the same time. The pusher motor 42 drives the lead screw 43 to rotate in the opposite direction. The nut slider 44 drives the pusher plate 46 to slide backward, making it convenient for the user to put vegetables into the feeding trough again.

[0088] When the user wants to replace the cutting blade, they can rotate the locking knob, then open the cover 31, then unscrew the locking bolt 66, then remove the slicing blade, then install the dicing blade 8 or shredding blade 7 onto the motor shaft of the cutting motor 5, tighten the locking bolt 66 again to fix the dicing blade 8 or shredding blade 7, then close the cover 31, the fifth micro switch 37 is triggered, the fifth micro switch connects the circuit of the cutting motor 5 and sends a signal to the controller 23.

[0089] When a user wants to change the slicing thickness of the cutting blade, they can rotate the locking knob to open the cover 31, then loosen the locking bolt 66, and then rotate the adjusting nut 65. The rotation of the adjusting nut 65 causes the external threaded cylinder 68, the movable cutter head 61, and the movable blade 62 to move forward or backward, while the fixed blade 63 remains stationary. This changes the size of the slicing gap 64 between the movable blade 62 and the fixed blade 63, thereby adjusting the slicing thickness.
