Description

Technical Field

[0001] This invention belongs to the field of agricultural product processing equipment, specifically relating to an automated water chestnut destemming device. Background Technology

[0002] Currently, water chestnut processing is increasingly done using mechanical equipment. Removing the stem is a crucial step in this process. Existing peeling machines primarily use a cutting method to peel and remove the stem. However, when removing the stem, the cutting blades in these machines generally have a fixed angle. This makes it difficult to handle irregularly shaped water chestnuts with angled stems. To cleanly remove the stem, the cutting depth must be increased, resulting in significant waste of the edible portion of the water chestnut. Therefore, a device is needed that offers better stem removal efficiency, reduces waste of edible parts, and improves the quality of stem removal. Summary of the Invention

[0003] To overcome the shortcomings and problems of existing technologies, this invention provides an automated water chestnut stem-removing device that achieves better stem removal results while reducing waste of edible parts, thereby improving the quality of stem removal.

[0004] This invention is achieved through the following technical solution: An automated water chestnut stem removal device includes a rotating needle plate device, a corresponding pressing device, a fork-like device for removing water chestnuts from the rotating needle plate device on one side of the pressing device, a bottom stem milling cutter mechanism opposite the fork-like device, and a head stem removal device on one side of the fork-like device. The head stem removal device includes a plane measuring mechanism and a cutting mechanism. The angle of the cutting plane is controlled by the plane measuring mechanism, which is a multi-point displacement measuring device. The cutting mechanism includes a flat cutting tool holder, three guide rods, and three linear drive mechanisms arranged in a triangular pattern. The three linear drive mechanisms are respectively connected to the three guide rods, and the three guide rods are all connected to the flat cutting tool holder. The flat cutting tool holder is equipped with a flat cutting head.

[0005] The rotating needle plate device includes a first rotating drive mechanism, which is connected to a turntable, and the turntable is provided with needles around its circumference.

[0006] The fruit pressing device includes a fruit pressing linear drive mechanism, which is connected to at least two pressing needles.

[0007] The forklift device includes a horizontal displacement drive mechanism, which is connected to a second rotary drive mechanism. The second rotary drive mechanism is connected to a telescopic drive mechanism perpendicular to the rotation axis, and the telescopic drive mechanism is connected to a double fork.

[0008] The bottom end mill mechanism includes a rotary drive motor connected to a bottom end mill, the chipping surface of which is double crescent-shaped.

[0009] In this invention, the planar measuring mechanism of the stem removal device can measure the optimal cutting surface of the water chestnut stem. The cutting mechanism controls the angle of the cutting plane by the planar measuring mechanism, thereby cutting the stem. When dealing with water chestnuts with irregular growth and inconsistent stem growth angles, the stem can be effectively removed, reducing the waste of edible parts. Attached Figure Description

Detailed Implementation

[0012] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1As shown, an automated water chestnut stem removal device includes a rotating needle plate device 100, a pressing device 200 corresponding to the rotating needle plate device 100, a forking device 300 for removing water chestnuts from the rotating needle plate device 100 on one side of the pressing device 200, a bottom stem milling cutter mechanism 400 opposite the forking device 300, and a top stem removal device 500 on one side of the forking device 300. The top stem removal device 500 includes a plane measuring mechanism and a cutting mechanism, and the angle of the cutting plane is controlled by the plane measuring mechanism.

[0014] like Figure 2 As shown, the rotating needle plate device 100 is used for orderly feeding of water chestnuts. The rotating needle plate device 100 includes a first rotating drive mechanism 110, which is a first geared rotary motor. The first geared rotary motor is connected to a turntable 120, and the turntable 120 has pins 121 arranged around its surface. During operation, the water chestnuts are inserted into the pins 121 with their stems facing the turntable 120. The first geared rotary motor drives the turntable 120 to rotate, causing the water chestnuts inserted into the pins 121 to rotate and be fed in an orderly manner.

[0015] like Figure 3 As shown, the pressing device 200 is used to press the water chestnuts onto the pins 121 of the turntable 120 to prevent them from loosening and falling off. The pressing device 200 includes a pressing linear drive mechanism 210, which is a linear cylinder connected to two pressing pins 211. When the forking device 300 is forking, the water chestnuts need to be fixed to prevent them from loosening and falling off. When the turntable 120 rotates the water chestnuts to the corresponding position, the linear cylinder drives the output rod to push out, and the pressing pins 211 can then press the water chestnuts onto the pins 121. The two pressing pins 211 can prevent the water chestnuts from rotating, thus improving stability.

[0016] like Figure 4As shown, the fork-taking device 300 includes a horizontal displacement drive mechanism 310, which is connected to a second rotary drive mechanism 320. The second rotary drive mechanism 320 is connected to a telescopic drive mechanism 330 perpendicular to the rotation axis, and the telescopic drive mechanism 330 is connected to a double fork 331. The horizontal displacement drive mechanism 310 includes a horizontal slide rail 311 and a lead screw motor 312. The second rotary drive mechanism 320 is a second reduction rotary motor, which is mounted on a slide table of the horizontal slide rail 311. The lead screw motor 312 is connected to the slide table, and the lead screw motor 312 drives the slide table to make the second reduction rotary motor slide along the horizontal slide rail 311. The telescopic drive mechanism 330 is an electric slide rail table, and the double fork 331 is mounted on the electric slide rail table. The electric slide rail table drives the double fork 331 to slide along the electric slide rail table, realizing the extension and retraction of the double fork 331. Through the joint drive of the horizontal displacement drive mechanism 310, the second rotation drive mechanism 320 and the telescopic drive mechanism 330, the double fork 331 can perform horizontal displacement and multi-angle swing extension and retraction, which can pick up the water chestnut from the rotating needle plate device 100 and move it to other positions for the next step of operation.

[0017] like Figure 1 , 8 As shown, the bottom stem milling mechanism 400 includes a rotary drive motor 410, which is connected to a bottom stem milling cutter 420. The cutting surface of the bottom stem milling cutter 420 is double crescent-shaped. Since a portion of the bottom stem root of the water chestnut protrudes into the flesh, the double crescent-shaped cutting surface can conform to the surface structure of the flesh of the bottom stem part of the water chestnut, milling away the bottom stem root protruding into the flesh. At the same time, it effectively reduces the amount of chips from the flesh part when milling the bottom stem, thus reducing the waste of edible parts.

[0018] like Figure 5 , 6 As shown, the stem removal device 500 includes a plane measuring mechanism and a cutting mechanism. The cutting mechanism controls the angle of the cutting plane. Through the cooperation of the plane measuring mechanism and the cutting mechanism, the stem of the water chestnut can be effectively removed, while reducing the waste of edible parts. The plane measuring mechanism is a multi-point displacement measuring device 510, which is a three-point displacement meter. When the fork-lifting device 300 moves the water chestnut to the front of the three-point displacement meter and presses it against the three measuring rods of the three-point displacement meter, the three-point displacement meter measures the tilt angle of the stem of the water chestnut. At the same time, the optimal cutting plane is obtained and the cutting depth is calculated using the principle of three points forming a plane.

[0019] like Figure 5 , 7As shown, the cutting mechanism includes a flat-cutting blade holder 522, three guide rods 521, and three linear drive mechanisms 520. The three linear drive mechanisms 520 are arranged in a triangular pattern and are connected to the three guide rods 521 respectively. All three guide rods 521 are connected to the flat-cutting blade holder 522, which is equipped with a flat-cutting blade head 523. Each of the three linear drive mechanisms 520 is a linear stepper motor. A spring is arranged around the edge of the flat-cutting blade holder 522, and all three guide rods 521 are connected to the spring. After the measuring mechanism measures the optimal cutting plane of the water chestnut, the three linear stepper motors independently drive the three guide rods 521 to perform linear movements. By adjusting the angle of the flat-cutting blade holder 522, the cutting plane and cutting depth of the flat-cutting blade head 523 are controlled, thus adjusting the flat-cutting blade head 523 to the optimal cutting position. This reduces waste of edible parts when removing the water chestnut stem.

[0020] Working process: Water chestnuts are inserted into the pins 121 of the turntable 120 with their stems facing down. Then, the forking device 300 removes the water chestnuts from the rotating pin plate. Before forking, a linear cylinder drives a pressing pin 211 to press the water chestnuts onto the pins 121 of the turntable 120. During forking, the horizontal displacement drive mechanism 310, the second rotation drive mechanism 320, and the telescopic drive mechanism 330 work together to move the double fork 331 to the appropriate position and insert the water chestnuts into the pin plate. After the double fork 331 is inserted, the linear cylinder drives the pressing pin 211 to retract, at which point the forking device 300 can remove the water chestnuts from the pins 121. After the water chestnut is removed from the insert pin 121, the fork-taking device 300 moves the water chestnut to the bottom stem milling mechanism 400, where the bottom stem milling cutter 420 mills off the bottom stem of the water chestnut. After the bottom stem is milled off, the fork-taking device 300 moves the water chestnut to the three-point displacement meter and presses it against the three measuring rods of the three-point displacement meter. The three-point displacement meter measures the tilt angle of the water chestnut head and stem, and uses the principle of three points forming a plane to obtain the optimal cutting plane and calculate the cutting depth. After the measurement is completed, the fork-taking device 300 moves the water chestnut to the cutting mechanism, and then three linear stepper motors drive the flat cutting head 523 to adjust the cutting position according to the measurement data to remove the water chestnut head and stem.
