Description

Technical Field

[0001] The invention relates to the technical field of food machinery, in particular to a concave cutting device. Background Art

[0002] The roots of fruits and vegetables such as onions, garlic, and tomatoes must be removed before they are eaten, so the removal of the roots of such fruits and vegetables is a very important step for subsequent processing or consumption. The root cutting machines in the prior art mostly adopt the processing methods of flat cutting with a disc knife or manual cutting with a manual arc knife. These two methods not only have low cutting efficiency, but also have a large amount of cutting, and a part of the edible part is cut off, resulting in a low yield rate, causing waste of resources and increased costs. In addition, the product quality of the manual cutting method is difficult to guarantee, and there are safety hazards of cutting hands and high labor costs. At present, the deep processing industry of such fruits and vegetables urgently needs a root cutting device that has a fast cutting speed, clean cutting, and a high yield rate, while minimizing the amount of cutting and reducing resource waste.

[0006] The first driving mechanism drives the fixed seat to move downward, and the second driving mechanism drives the steel sleeve, the pressing shaft and the cutter to rotate together. When the bottom end of the pressing shaft contacts the fruits and vegetables, the pressing shaft moves upward due to the resistance of the fruits and vegetables, and the first bracket also moves upward. Under the action of the second bracket and the connecting rod, the knife handle drives the cutter to move downward in an arc. At this time, the cutter moves downward in an arc while rotating with the pressing shaft, so as to concavely cut the roots and stems of fruits and vegetables into an arc-shaped spherical shape. According to the cutting depth of different fruits and vegetables, the downward stroke of the first driving mechanism is set. When the downward stroke set by the first driving mechanism is completed, the first driving mechanism drives the cutter to reset upward to complete a concave cutting action.

[0007] Preferably, the cutter is arc-shaped, which better fits the root and stem parts of fruits and vegetables and reduces the amount of edible parts removed.

[0008] Preferably, the lower edge of the cutter is slightly higher than the bottom of the pressing shaft, ensuring that the cutter performs concave cutting after the fruits and vegetables are pressed and fixed at the bottom of the pressing shaft, preventing the fruits and vegetables from falling or flying out during cutting, causing safety hazards and reducing the yield.

[0009] Preferably, the output shaft of the first driving mechanism is connected to a sprocket, the sprocket engages a chain, the chain is fixed on a fixed seat, the first driving mechanism drives the sprocket to rotate, the sprocket drives the chain to move up and down, thereby driving the fixed seat to move up and down.

[0010] Preferably, the bottom of the pressing shaft is fixedly connected to a positioning column, and the lower edge of the cutting knife is slightly higher than the bottom of the positioning column, so that the positioning column is conducive to better fixing the fruits and vegetables.

[0011] Preferably, the device for concave cutting of roots and stems of fruits and vegetables also includes a conveyor belt, on which a material receiving seat is provided; a position detection mechanism is provided at the lower end of the pressing shaft, and the position detection mechanism is communicatively connected with a driving mechanism of the conveyor belt. The roots and stems of fruits and vegetables are placed upward on the material receiving seat and move with the conveyor belt. When the position detection mechanism detects that the fruits and vegetables are located below the pressing shaft, the conveyor belt driving mechanism stops moving, the conveyor belt stops running, the first driving mechanism and the second driving mechanism start to perform concave cutting. With the cooperation of the conveyor belt, the concave cutting device can perform continuous concave cutting, thereby improving production efficiency.

[0012] Preferably, the material receiving seat is a cylindrical structure; when fruits and vegetables are placed on the material receiving seat, a portion of them is located inside the cylindrical structure, which effectively fixes the round fruits and vegetables and facilitates transportation and concave cutting.

[0013] Preferably, the first driving mechanism and the second driving mechanism are both motors.

[0014] Compared with the prior art, the device for concave cutting of roots and stems of fruits and vegetables provided by the present invention can cut the roots and stems of fruits and vegetables in a concave state while the cutter makes a circular motion downward. Under the premise of ensuring that the roots and stems are cut cleanly, the cutting of edible parts is reduced, the yield is improved, resource waste is minimized, and production costs are reduced; manual operation is avoided, safety hazards are eliminated, and labor costs are reduced; the device has a simple and practical structure, is easy to manufacture, reduces the cost of the device, and is suitable for popularization and application.
