Description

Technical Field

[0001] This utility model relates to the field of vegetable processing technology, and in particular to an adaptive adjustment vegetable cutter. Background Technology

[0002] With the increasing demand for automation in food processing, traditional vegetable cutters are gradually failing to meet market needs due to their limited functionality and poor adaptability. Current technologies for vegetable cutters mostly employ fixed blades and uniform speed transmission designs, resulting in the following drawbacks: 1. Low cutting precision: Traditional equipment cannot dynamically adjust cutting parameters (such as blade speed and stroke) according to the hardness or shape of the ingredients, leading to uneven slice thickness or ingredient breakage; 2. Insufficient adaptability: A single blade structure is difficult to adapt to different ingredients (such as leafy vegetables and root vegetables), requiring frequent blade changes and cumbersome operation; 3. High ingredient damage rate: Rigid pressing devices easily crush soft ingredients (such as tomatoes), causing juice loss or shape damage; 4. Safety hazards: The lack of a real-time safety protection mechanism means that the machine cannot be stopped quickly if the operator accidentally touches the blade or a foreign object enters the cutting area.

[0003] Furthermore, while existing patents (such as CN106313164B) disclose vegetable cutters that receive signals from a signal generator on the loading tray via a sensor control device to control the cutting blades, they employ a single-position detection mechanism, resulting in blind spots. Additionally, blade replacement relies on bolt fixing, leading to low efficiency. Therefore, there is an urgent need for a vegetable cutter with adaptive adjustment capabilities, high safety, and convenient maintenance. Utility Model Content

[0040] 3. Flexible pressing: The pressing cylinder 32 drives the pressing roller 31 to press down, the elastic buffer layer 311 adheres to the surface of the carrot, and the hydraulic buffer 36 absorbs vibration to prevent the food from being damaged.

[0041] 4. Dynamic cutting:

[0042] Servo motor 221 drives cam 222 to rotate, which in turn drives tool holder 24 and tool body 21 to move up and down reciprocally via connecting rod 223; distance sensor 23 detects the position of sensing column 27 in real time, and controller 5 adjusts the speed and angle of servo motor 221 according to the position deviation to ensure stable cutting stroke;

[0043] 5. Safety protection: If the operator's hand approaches the feed inlet, the infrared sensor 61 will trigger a signal, and the controller 5 will cut off the power to all drive units and lock the emergency stop switch 62 within 0.1 seconds.

[0044] In this embodiment, the magnetic connection groove 224 between the magnetic blade body 21 and the blade holder 24 enables a quick blade change in 3 seconds, adapting to different cutting needs; the staggered detection layout of the dual distance sensors 23 and the sensing column 27 eliminates the blind zone of a single sensor, achieving a positioning accuracy of ±0.1mm.

[0045] The hydraulic buffer 36 and the elastic buffer layer 311 form a double shock absorption, increasing the integrity rate of ingredients to 98%; the lateral adaptive adjustment of the guide wheel 33 supports continuous processing of ingredients with a width of 20-150mm.
