Description

Technical Field

[0001] This utility model relates to a vegetable cutter that has adaptive compensation for feeding speed and thrust. Background Technology

[0002] In the existing technology, most vegetable cutters on the market use rigid push rods or push plate-type feeding devices. This type of structure itself basically does not have the ability to adjust elastically. The feeding speed is directly determined by the speed of the drive motor, and the motor speed is usually difficult to adjust in a timely and precise manner according to the thickness of the food.

[0003] When ingredients of different thicknesses or sizes are mixed and processed, the feeding speed and the pressure state of the ingredients are not matched, which can easily lead to unstable feeding speed at the cutting plate, resulting in uneven slice thickness, poor cross-sectional quality, and even problems such as jamming and deformation. Utility Model Content

[0004] The purpose of this invention is to provide a vegetable cutter that adapts to ingredients of different thicknesses, ensures uniform and efficient cutting, and has adaptive compensation for feeding speed and thrust.

[0005] The purpose of this utility model is achieved as follows: A vegetable cutter with adaptive compensation for feeding speed and thrust includes a main unit and a cutting box. The main unit is equipped with a feeding chute, a cutting motor and an automatic feeding mechanism. The main unit has a discharge port corresponding to the feeding chute. The cutting box has a built-in cutting blade, the bottom of the cutting box has a discharge port, the cutting box is connected to the main unit, the cutting box has a feed port that connects to the feed trough, the cutting motor is connected to the cutting blade, and the cutting motor drives the cutting blade to rotate and cut vegetables. The automatic feeding mechanism includes a pushing device and an elastic feeding component. The elastic feeding component is slidably disposed in the feeding trough. The pushing device includes a drive motor and a transmission component for converting rotational motion into linear motion. The drive motor and the transmission component are disposed in the main unit housing. The input end of the transmission component is connected to the drive motor, and the output end of the transmission component is connected to the elastic feeding component. The drive motor drives the elastic feeding component to move linearly along the length direction of the feeding trough through the transmission component.

[0006] By setting up an automatic feeding mechanism inside the main unit and using an elastic feeding component that can reciprocate linearly along the length of the feeding groove, the food can be automatically and continuously pushed. During the feeding process, the elastic feeding component can generate elastic compression and rebound within a certain stroke, thereby adaptively compensating for food of different thicknesses and hardnesses. This makes the feeding speed at the cutting disc more stable and consistent, avoiding problems such as uneven slice thickness, jamming, or deformation caused by mismatch between feeding speed and food thickness. The cutting effect is uniform and neat, while reducing manual intervention and improving cutting efficiency and safety.

[0007] The objective of this utility model can also be achieved by the following technical measures: Furthermore, the transmission assembly includes a lead screw and a nut. The lead screw is connected to the shaft of a drive motor, the nut is sleeved on the lead screw, and the nut is connected to an elastic pusher assembly. The drive motor drives the lead screw to rotate, the nut slides along the length of the lead screw, and the elastic pusher assembly moves synchronously with the nut.

[0008] The transmission assembly adopts a screw and nut joint structure. The screw is driven by a drive motor to rotate, and the nut slides smoothly along the length of the screw, thereby driving the elastic pusher assembly to make precise linear reciprocating motion. This structure reliably converts rotational motion into linear motion, with high transmission accuracy and smooth operation. Moreover, the screw-nut mechanism has a simple structure, low cost, and good load-bearing capacity, making it easy to control the pusher stroke and speed, and improving the stability and reliability of the whole machine operation.

[0009] Furthermore, it also includes an anti-rotation guide rod, which is installed inside the main unit housing. The nut has a sliding hole, which is fitted onto the anti-rotation guide rod. When the lead screw rotates, the nut slides along the length of the anti-rotation guide rod, thereby limiting the sliding direction of the nut.

[0010] By setting an anti-rotation guide rod inside the main unit and opening a sliding hole on the nut to match it, the nut can only slide along the length of the anti-rotation guide rod when the screw rotates and cannot rotate with the screw. This effectively restricts the direction of movement of the nut and avoids the nut from deflecting, jamming or shaking, making the linear movement of the pusher assembly smoother and more stable.

[0011] Furthermore, the nut is provided with an extension plate, which is connected to the elastic pusher assembly.

[0012] By setting an extension plate on the nut and connecting the extension plate to the elastic pusher assembly, a reliable force transmission and assembly connection between the nut and the pusher assembly is achieved; this structure enables the linear sliding of the nut to be efficiently and directly transmitted to the elastic pusher assembly.

[0013] Furthermore, the elastic pusher assembly includes a pusher panel, a spring, and a support base. The support base has through holes spaced apart. A column is provided on the back of the pusher panel. The column is inserted into the corresponding through hole to realize the movable connection between the pusher panel and the support base. The spring is sleeved on the column, with one end of the spring abutting against the pusher panel and the other end abutting against the support base. The spring constitutes the reset mechanism of the pusher panel.

[0014] During the feeding process, when the thickness or hardness of the food changes, the feeding panel can generate elastic displacement under the action of the spring, apply a moderate and flexible pushing force to the food, adaptively compensate for the size differences of different foods, make the feeding more stable, reduce the squeezing damage to the food, and at the same time, the spring drives the feeding panel to automatically reset, ensuring the smooth operation of the next cycle.

[0015] Furthermore, the surface of the pusher panel is provided with protrusions at intervals.

[0016] By setting multiple protrusions at intervals on the surface of the pusher panel, the friction between the pusher panel and the food is increased, making it easier and more reliable for the pusher panel to contact the food during the pushing process. This effectively prevents the food from slipping, deviating, or rotating when subjected to force, thus ensuring that the food enters the cutting plate with a predetermined posture and a stable speed, improving the uniformity and stability of cutting.

[0017] Furthermore, it also includes a controller, wherein a first micro switch is provided on the main unit near the feed inlet, a second micro switch is provided on the main unit away from the feed inlet, and a contact part is provided on the support base; The controller is mounted on the main unit chassis. The first micro switch, the second micro switch, the drive motor, and the vegetable cutting motor are electrically connected to the controller. The controller controls the start and stop of the drive motor and the vegetable cutting motor. The controller controls the drive motor to start and rotate forward. The drive motor drives the elastic pushing component to slide along the feeding groove towards the feeding port. When the contact part touches the first micro switch, the first micro switch sends a signal to the controller. The controller disconnects the power supply of the vegetable cutting motor and controls the drive motor to reverse. The drive motor drives the elastic pushing component to slide along the feeding groove away from the feeding port. When the contact part touches the second micro switch, the second micro switch sends a signal to the controller, and the controller disconnects the power supply to the drive motor and the cutting motor.

[0018] When the contact part touches the first micro switch, the controller cuts off the power to the cutting motor and controls the drive motor to reverse, causing the elastic pusher assembly to automatically return along the feeding chute. When the contact part touches the second micro switch, the controller simultaneously cuts off the power to both the drive motor and the cutting motor, completing one work cycle and automatically stopping. At this time, the elastic pusher assembly has retracted, and the user can safely put food into the feeding port, reducing the risk of misoperation and accidental contact with the blade, and improving the safety of equipment use.

[0019] The beneficial effects of this utility model are as follows: This invention achieves automatic and continuous feeding of ingredients by setting an automatic feeding mechanism inside the main unit and using an elastic feeding component that can reciprocate linearly along the length of the feeding groove. During the feeding process, the elastic feeding component can generate elastic compression and rebound within a certain stroke, thereby adaptively compensating for ingredients of different thicknesses and hardnesses. This makes the feeding speed at the cutting disc more stable and consistent, avoiding problems such as uneven slice thickness, jamming, or deformation caused by mismatch between feeding speed and ingredient thickness. The cutting effect is uniform and neat, while reducing manual intervention and improving cutting efficiency and safety.

[0020] In this invention, during the feeding process, when the thickness or hardness of the food changes, the feeding panel can generate elastic displacement under the action of the spring, applying a moderate and flexible pushing force to the food, adaptively compensating for the size differences of different foods, making the feeding more stable, reducing the squeezing damage to the food, and at the same time, the spring drives the feeding panel to automatically reset, ensuring the smooth progress of the next cycle.

[0021] This invention increases the friction between the pusher panel and the food by setting multiple protrusions at intervals on the surface of the pusher panel. This makes it easier and more reliable for the pusher panel to contact the food during the pushing process, effectively preventing the food from slipping, deviating or rotating when subjected to force. This ensures that the food enters the cutting disc with a predetermined posture and a stable speed, improving the uniformity and stability of cutting. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments: Implementation examples, in conjunction with Figures 1 to 10 As shown, a vegetable cutter with adaptive compensation for feeding speed and thrust includes a main unit box 1 and a cutting box 2. The main unit box 1 is provided with a feeding trough 11, a cutting motor and an automatic feeding mechanism. The main unit box 1 has a discharge port 12 at the position corresponding to the feeding trough 11. The cutting box 2 has a built-in cutting blade, and the bottom of the cutting box 2 is provided with a discharge port 21. The cutting box 2 is connected to the main unit box 1. The cutting box 2 has a feed port 22 that connects to the feed trough 11. The cutting motor is connected to the cutting blade, and the cutting motor drives the cutting blade to rotate and cut vegetables. The automatic feeding mechanism includes a pushing device 3 and an elastic feeding component 4. The elastic feeding component 4 is slidably disposed in the feeding trough 11. The pushing device 3 includes a drive motor 31 and a transmission component 32 for converting rotational motion into linear motion. The drive motor 31 and the transmission component 32 are disposed in the main housing 1. The input end of the transmission component 32 is connected to the drive motor 31, and the output end of the transmission component 32 is connected to the elastic feeding component 4. The drive motor 31 drives the elastic feeding component 4 to move linearly along the length direction of the feeding trough 11 through the transmission component 32.

[0033] Furthermore, the transmission assembly 32 includes a lead screw 321 and a nut 322. The lead screw 321 is connected to the shaft of the drive motor 31. The nut 322 is sleeved on the lead screw 321. The nut 322 is connected to the elastic pusher assembly 4. The drive motor 31 drives the lead screw 321 to rotate, and the nut 322 slides along the length of the lead screw 321. The elastic pusher assembly 4 moves synchronously with the nut 322.

[0034] Furthermore, it also includes an anti-rotation guide rod 5, which is installed inside the main unit housing 1. The nut 322 has a sliding hole 3221, and the sliding hole 3221 of the nut 322 is fitted onto the anti-rotation guide rod 5. When the lead screw 321 rotates, the nut 322 slides along the length direction of the anti-rotation guide rod 5, thereby restricting the sliding direction of the nut 322.

[0035] Furthermore, the nut 322 is provided with an extension plate 3222, which is connected to the elastic pusher assembly 4.

[0036] Furthermore, the elastic pusher assembly 4 includes a pusher panel 41, a spring 42, and a support base 43. The support base 43 has through holes 431 spaced apart. A column 411 is provided on the back of the pusher panel 41. The column 411 is inserted into the corresponding through hole 431 to realize the movable connection between the pusher panel 41 and the support base 43. The spring 42 is sleeved on the column 411. One end of the spring 42 abuts against the pusher panel 41, and the other end of the spring 42 abuts against the support base 43. The spring 42 constitutes the reset mechanism of the pusher panel 41.

[0037] Furthermore, the surface of the pusher panel 41 is provided with protrusions 412 at intervals.

[0038] Furthermore, it also includes a controller 6, a first micro switch 7 is provided on the main unit 1 near the feed inlet 22, a second micro switch 8 is provided on the main unit 1 away from the feed inlet 22, and a contact part 432 is provided on the support base 43; The controller 6 is mounted on the main unit 1. The first micro switch 7, the second micro switch 8, the drive motor 31, and the vegetable cutting motor are electrically connected to the controller 6. The controller 6 controls the start and stop of the drive motor 31 and the vegetable cutting motor. The controller 6 controls the drive motor 31 to start and rotate forward. The drive motor 31 drives the elastic pushing component 4 to slide along the feeding groove 11 towards the feeding port 22. When the contact part 432 touches the first micro switch 7, the first micro switch 7 sends a signal to the controller 6. The controller 6 disconnects the power supply of the vegetable cutting motor and controls the drive motor 31 to reverse. The drive motor 31 drives the elastic pushing component 4 to slide along the feeding groove 11 away from the feeding port 22. When the contact part 432 touches the second micro switch 8, the second micro switch 8 sends a signal to the controller 6, and the controller 6 disconnects the power supply to the drive motor 31 and the vegetable cutting motor.

[0039] How to use a vegetable cutter that adaptively compensates for feeding speed and thrust: When using this vegetable cutter with adaptive compensation for feeding speed and thrust, first place the equipment stably and turn on the power. Confirm that the elastic pushing component 4 has retracted to the position close to the second micro switch 8 under the control of the drive motor 31 and the controller 6. At this time, the user can neatly put the food to be cut into the feeding trough 11 through the feeding port 12 corresponding to the feeding trough 11 position on the main unit box 1. Then the controller 6 is started, which powers the drive motor 31 and the cutting motor in sequence. The cutting motor drives the cutting disc to rotate at high speed. The drive motor 31 rotates forward and pushes the elastic pushing component 4 towards the feed port 22 through the screw 321-nut 322 mechanism, continuously and stably pushing the food to the cutting disc to complete the cutting. The cut pieces are discharged through the discharge port 21 at the bottom of the cutting box 2. When the contact part 432 on the support base 43 touches the first micro switch 7, the controller 6 cuts off the power to the cutting motor and controls the drive motor 31 to reverse. The elastic pushing component 4 slides back along the feeding groove 11. When the contact part 432 reaches the position of the second micro switch 8, the controller 6 cuts off the power to the drive motor 31 and the cutting motor, completing one work cycle. After the pushing component returns and the motor stops, the user can safely put the next batch of ingredients into the feeding port 12 again, realizing continuous, efficient and safe cutting operations.

[0040] The working principle of adaptive compensation: When the ingredients are thin or soft, the pusher panel 41 only has a small displacement, the spring 42 has a small compression, and the pushing force is gentle, ensuring that the ingredients are smoothly fed into the cutting plate. When the food is thick or hard and the local resistance increases, the pusher panel 41 is pushed back by the reaction force of the food during the forward movement. The spring 42 is further compressed to store energy, so that the pusher panel 41 moves backward relative to the support base 43 to buffer, thereby adaptively compensating for the feeding speed and pushing force, avoiding jamming or overload caused by rigid pushing, and ensuring that the food fed into the cutting disc always moves forward at a basically constant and stable speed, ensuring that the slices are of uniform thickness and the cut surface is neat.
