Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing equipment technology, specifically a water chestnut end-face peeling device. Background Technology

[0002] As a food and medicinal plant, water chestnuts require peeling as a crucial step in their processing. Existing water chestnut peeling machines primarily employ a cutting method, which is relatively mature for peeling the cylindrical sides of water chestnuts. However, peeling the end faces still has significant drawbacks: water chestnuts have a unique shape, with one end being a nearly flat plane (hereinafter referred to as the "flat end") and the other end being an inclined plane (hereinafter referred to as the "inclined end face"), and the angle of inclination varies among different water chestnuts. Current end-face peeling devices generally use a fixed horizontal cutting method, meaning the axis of the rotating cutter remains vertical, and the cutting is done horizontally regardless of the angle of the water chestnut's tilted end. This method results in a large amount of flesh being removed from the higher side of the tilted end—to ensure complete removal of the skin from the tilted end, the cutter must cut to the lowest point of the tilted end, causing excess flesh on the higher side to be removed as well, resulting in significant waste. To solve the above problems, there is an urgent need for an end-face peeling device that can adapt to the angle of the tilted end face of the water chestnut and cut precisely, so as to retain the pulp to the maximum extent while ensuring thorough peeling.

[0019] Please see Figures 1 to 2 This utility model provides an embodiment of a water chestnut end-face peeling device, comprising a worktable 16, a control system, a conveying mechanism mounted on the worktable 16 for conveying water chestnuts to a cutting station, a cutting mechanism mounted on the worktable 16 for cutting the horizontal end face of the water chestnuts, a three-point measuring component 3 mounted on the worktable 16 for detecting the tilt angle of the tilted end face of the water chestnuts, and a rotating cutter 7 mounted on the worktable 16 via a cutter adjustment mechanism; both the three-point measuring component 3 and the cutter adjustment mechanism are electrically connected to the control system, and the cutter adjustment mechanism is used to adjust the tilt angle of the rotating cutter 7; the control system can receive the tilt angle information of the water chestnut end face and control the operation of the rotating cutter 7 through the cutter adjustment mechanism, which is used to adjust the tilt angle of the rotating cutter 7; the control system receives... After receiving the tilt angle information, the control mechanism adjusts the blade to make the axis of the rotating blade 7 perpendicular to the tilted end face of the water chestnut, and the rotating blade cuts and peels the tilted end face of the water chestnut. Addressing the problems of existing water chestnut peeling devices that cannot adapt to different tilted end faces, excessive removal of flesh from the higher side of the tilted end face, poor flatness of the cut end face, and impact on subsequent processing quality, this application uses a three-point measuring component 3 to detect the tilt angle of the water chestnut's tilted end face. The control system controls the blade adjustment mechanism to adjust the tilt angle of the rotating blade 7, making the axis of the rotating blade 7 perpendicular to the tilted end face before cutting. This adapts to different tilted end faces of water chestnuts, achieving precise cutting, ensuring thorough peeling while maximizing the retention of flesh and reducing flesh waste due to over-cutting.

[0020] In one embodiment, the three-point measuring component 3 may be a multi-point displacement measuring device mentioned in application number CN202410848086.7. This device is a three-point displacement meter. When the water chestnut moves under the three-point displacement meter and presses against the three measuring rods of the three-point displacement meter, the three-point displacement meter will measure the tilt angle of the water chestnut head and stem part, and at the same time use the principle of three points forming a surface to obtain the optimal cutting plane and calculate the cutting depth.

[0021] In one embodiment, the conveying mechanism includes a feeding plate 6 mounted on a worktable 16 via a first Y-axis slide 5. The feeding plate 6 has several feeding bosses 4 on which water chestnuts are placed. The first Y-axis slide 5 consists of a lead screw, a nut, and a driving component, i.e., a lead screw and nut mechanism. The driving component drives the lead screw to rotate, and the rotational motion is converted into linear motion through the threaded engagement between the lead screw and the nut, thereby driving the feeding plate 6, which is fixed to the nut, to move smoothly along the guide structure of the worktable 16. The feeding bosses 4 are adjusted according to the shape of the water chestnuts. The shape and size design, through the limiting effect of the bosses, ensures that the water chestnuts are stably placed on it. Several feeding bosses 4 are evenly distributed along the length of the feeding plate 6 to achieve synchronous conveying of batches of water chestnuts. Among them, the feeding bosses 4 achieve independent positioning of water chestnuts, avoiding collisions and displacement of water chestnuts during the conveying process, and ensuring the accuracy of subsequent processes. The design of multiple feeding bosses 4 enables batch conveying, which greatly improves processing efficiency. In addition, the feeding bosses 4 are provided with notches, and the water chestnuts are placed in the notches to avoid displacement of water chestnuts during the conveying process, further improving positioning accuracy.

[0022] In one embodiment, a first X-axis slide 1 is connected to the worktable 16 via a second Y-axis slide 18. A cutter adjustment mechanism is fixed to the output end of the first X-axis slide 1, and the first X-axis slide 1 is connected to the control system. A three-point measuring component 3 is fixed to the second Y-axis slide 18 via a connecting plate 19. A material handling component is provided on the worktable 16 to transfer water chestnuts from the loading boss 4 to the cutting station. The first Y-axis slide 5 and the first X-axis slide 1 can be common linear slides, such as a lead screw and nut mechanism or a rodless mechanism. The cylinder enables the cutting knife adjustment mechanism to move in the Y and X axes. The cutting knife adjustment mechanism consists of a multi-degree-of-freedom robotic arm. The robotic arm's execution end is equipped with a rotary motor 2 and a rotary cutter 7 to form a cutting unit. The tilt angle information fed back by the three-point measuring component 3 is converted into motion control commands for the robotic arm, driving the various joints of the robotic arm to move in tandem, causing the rotary cutter 7 to rotate around the spatial coordinate axis until the axis of the rotary cutter 7 is perpendicular to the tilted end face of the water chestnut. At the same time, the rotary motor 2 drives the rotary cutter 7 to rotate at high speed, generating cutting power to complete the peeling operation.

[0023] In one embodiment, the material handling assembly includes a support plate 10 fixed to the worktable 16 and a movable component 9 connected to the support plate 10 via a Z-axis moving mechanism 15. A second X-axis slide 20 is fixed to the movable component 9, and two insertion rods 12 for transferring water chestnuts from the loading boss 4 to the cutting station are provided on the output end of the second X-axis slide 20. The Z-axis moving mechanism 15 drives the movable component 9 to move up and down in the vertical direction, and the sliding connection between the movable component 9 and the worktable 16 ensures the stability of the vertical movement. During material handling, the Z-axis moving mechanism 15 drives the movable component 9 to move down so that the insertion rods 12 are aligned with the water chestnuts, and then the second X-axis slide 20 drives the insertion rods 12 to move up and down. 2. The robot extends and inserts the water chestnut to grasp it. Then, the second X-axis slide 20 resets and transfers the water chestnut to the cutting station. Then, the Z-axis moving mechanism 15 starts and moves the water chestnut upward to contact the three-point measuring component 3 above, realizing the tilt angle detection of the tilted end face of the water chestnut. After the detection is completed, the Z-axis moving mechanism 15 resets, thereby moving the water chestnut to the cutting station. Then, according to the tilt angle information fed back by the three-point measuring component 3, the robot arm drives the rotary cutter 7 to rotate around the spatial coordinate axis until the axis of the rotary cutter 7 is perpendicular to the tilted end face of the water chestnut. At the same time, the rotary motor 2 drives the rotary cutter 7 to rotate at high speed, generating cutting power to complete the peeling operation.

[0024] In one embodiment, the Z-axis moving mechanism 15 includes a drive motor fixed to the support plate 10, an internal threaded sleeve fixed to the moving part 9, and a screw fixed to the output end of the drive motor and threadedly connected to the internal threaded sleeve. The end of the screw away from the drive motor is rotatably connected to the worktable 16, thereby realizing the up-and-down movement of the moving part 9. The cutting mechanism includes a cutting motor fixed to the worktable 16, and a horizontal cutter 8 is fixed to the output end of the cutting motor for cutting the flat end face of the water chestnut. Specifically, when the insert rod 12 extends and inserts into the water chestnut to grasp it, after the second X-axis slide 20 resets and transfers the water chestnut to the cutting station, the Z-axis moving mechanism 15 starts, first moving the water chestnut downward, and the flat end face of the water chestnut will move to the horizontal cutter 8, thereby realizing the cutting of the flat end of the water chestnut. Then the Z-axis moving mechanism 15 starts in reverse, thereby moving the water chestnut upward to detect the tilt angle in the tilted end face.

[0025] In one embodiment, a lever 11 is rotatably connected to the movable member 9, one end of the lever 11 is attached to the insert rod 12, and a baffle 13 is fixedly connected to the movable member 9. The lever 11 is pressed against the baffle 13 under the action of the elastic component, and the lever 11 is located between the feeding boss 4 and the baffle 13, so that the water chestnuts after both ends have been cut can be pushed out from the insert rod 12. The specific process is as follows: after both ends of the water chestnuts have been cut, the second X-axis slide 20 will be activated, thereby driving the water chestnuts towards the... The lever 11 moves in a certain direction, and during the movement, the lever 11 limits the water chestnut, thereby pulling the water chestnut out from the insert 12, thus realizing the feeding of the water chestnut; wherein, the elastic component includes a first boss fixed to the lever 11, a second boss fixed to the moving part 9, and a tension spring 14 for connecting the first boss and the second boss, thereby realizing the elastic connection of the lever 11 and preventing the end of the insert 12 from hitting the lever 11 when it is inserted, thereby damaging the lever 11.

[0026] In one embodiment, a camera 17 is fixedly connected to the connecting plate 19, and the camera 17 is connected to the control system. Before the insertion rod 12 inserts the water chestnut along the X-axis, the camera 17 takes a picture of the water chestnut on the feeding plate 6. The control system then calculates the distance that the feeding plate 6 should move based on the actual size of the water chestnut in the picture, thereby controlling the movement distance of the water chestnut along the Y-axis. This ensures that the center line of the water chestnut along the X-axis is perpendicular to the center line of the three-point measuring component 3 and is located in the same plane, thereby improving the accuracy of the three-point measuring component 3 in detecting the tilted end face of the water chestnut. Furthermore, when the insertion rod 12 inserts the water chestnut, it will pull the water chestnut out of the feeding boss 4. Because the water chestnuts are of different sizes, the control system will calculate the distance the second X-axis slide 20 moves based on the previous photos, thereby controlling the distance the water chestnut moves along the X-axis (that is, the distance the water chestnut is pulled out of the feeding boss 4), thus ensuring that the center line of the water chestnut along the Z-axis coincides with the center line of the three-point measuring component 3. Therefore, the introduction of the camera 17 can control the distance the water chestnut moves along the X-axis and Y-axis, so as to achieve the coincidence of the center line of the water chestnut along the Z-axis with the center line of the three-point measuring component 3.

[0027] Working principle: When the water chestnut moves to the cutting station, the moving part 9 moves downward, thereby driving the water chestnut to move downward (in the Z-axis direction). When the water chestnut contacts the bottom horizontal cutter 8, the flat end face of the bottom of the water chestnut is cut. Subsequently, the moving part 9 moves upward, and the upper inclined end face of the water chestnut contacts the detection end of the three-point measuring component 3. Based on the principle of three-point surface formation, the control system calculates the three-dimensional angle of the center normal of the inclined end face of the water chestnut and the position of this center in the Z-axis direction. After measurement, the control system controls the cutter adjustment mechanism to make the axial angle of the rotating cutter 7 consistent with the spatial angle of the center normal of the inclined end face of the water chestnut. Then, based on the spatial angle of the center normal, the control system controls the movement of the rotating cutter 7 in the X and Y axes, moving it to above the Z-axis direction of the water chestnut. Finally, based on the position of the center of the inclined end face of the water chestnut in the Z-axis direction, the control system controls the water chestnut to move upward to contact the cutter, completing the cutting of the inclined end face. After cutting, the moving part 9 moves the water chestnut downward, and finally, the insert rod 12 moves backward, pushing the water chestnut out, ready to be inserted for the next process.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
