[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-9 The present invention provides the following technical solution: a pomelo peeling machine, including a machine housing 6;

[0029] The pushing device 1, which is located on one side of the chassis 6, includes a pushing cylinder 7 mounted on the side wall of the chassis 6 via an extension frame and a gripper cylinder 8 mounted on the output end of the pushing cylinder 7, for fixing and pushing the grapefruit.

[0030] The grapefruit cutting device 2 located on the top of the chassis 6 includes optical axis frames 16 located on both sides of the top of the chassis 6. An upper blade cutting seat 13 is movably connected to the optical axis frames 16. A lower blade cutting seat 12 is located on the top of the chassis 6 and is located directly below the upper blade cutting seat 13. It is used to cut the top and bottom of the grapefruit during the process of pushing the grapefruit by the pushing device 1.

[0031] The fixing device 5 is located on the other side of the chassis 6. It includes a mounting base 24 located on the other side of the chassis 6 opposite to the extension frame. The bottom of the mounting base 24 is provided with a motor 25, and its output end is connected to a placement base 26 for fixing the cut grapefruit and driving it to rotate.

[0032] The transfer device 4, which is set between the grapefruit cutting device 2 and the fixing device 5, includes an ejector cylinder 31 installed inside the machine housing 6. A rotary cylinder 11 is installed at the output end of the ejector cylinder 31, and a gripper cylinder 10 is installed at the output end of the rotary cylinder 11. It is used to receive the grapefruit after the top and bottom are cut and transfer it to the fixing device 5.

[0033] The peeling device 3, which is installed on one side of the fixing device 5, includes a mounting bracket 22 installed on one side of the fixing device 5. Two running guide rails 21 are hinged on the mounting bracket 22. A connecting frame 28 is movably connected to the running guide rails 21. A swing frame 20 is fixedly connected to the running guide rails 21. The swing frame 20 is connected to the top of the optical axis frame 16 through a swing cylinder 19. The end of the connecting frame 28 is provided with a peeling knife 27, which is used to divide and peel the grapefruit peel on the fixing device 5.

[0034] Specifically, the top of the chassis 6 has an opening, and the interior has a storage cavity. The side wall of the storage cavity has a movable door, and the opening is located below the grapefruit cutting device 2. It can be used to store grapefruit peels after they fall off, and the movable door makes it easy to handle.

[0035] Specifically, a grapefruit base 9 is located below the output end of the push cylinder 7, and it is directly below the gripper cylinder 8, thus setting an initial positioning point for easy gripping by the gripper cylinder 8. At the same time, the grippers on both the gripper cylinder 8 and the gripper cylinder 10 are equipped with spikes to prevent the grapefruit from swaying when cutting the ends and peeling. The grippers on both the gripper cylinder 8 and the gripper cylinder 10 are 90° V-shaped and are equipped with cutting grooves. The gripper cylinder 20 is lower than the gripper cylinder 8. When the grapefruit is transferred from the gripper cylinder 8 to the gripper cylinder 20, the cutting grooves on the gripper cylinder 20 and the gripper cylinder 8 intersect to avoid interference.

[0036] Specifically, the optical axis frame 16 includes two optical axes, the top of which are connected by a gantry beam plate 17. Optical axis fixing blocks 15 are installed on both optical axes, and the two optical axis fixing blocks 15 are connected to each other by a mounting frame 14. An upper blade cutting seat 13 is fixedly connected to the mounting frame 14. A hinge seat 18 is provided at the bottom of the gantry beam plate 17. The optical axis fixing blocks 15 can be adjusted in height up and down on the optical axes, so that the upper blade cutting seat 13 can cut grapefruits of different sizes and heights.

[0037] Specifically, a swing cylinder 19 is hinged to the hinge seat 18, and a swing frame 20 is hinged to the output end of the swing cylinder 19. The swing frame 20 consists of two V-shaped tie rods and a connecting rod connecting the two. The ends of the two tie rods away from the connecting rod are fixedly connected to the running guide rails 21. An extension rod 29 is connected to the running guide rails 21 through a running block. A connecting frame 28 is provided at the end of the extension rod 29. A peeling knife 27 is installed on the connecting frame 28. A limiting block 23 is provided inside the mounting bracket 22. The mounting bracket 22 is located near the limiting block. A mounting plate is hinged to 23. One side of the mounting plate is connected to the running guide rail 21, and the other side is equipped with a top-blade cylinder 30. Its output end cooperates with the extension rod 29, moving the extension rod 29 on the running guide rail 21. This causes the extension rod 29 to drive the peeling knife 27 to move up and down to peel the grapefruit. The peeling knife 27 includes a light shaft 5, with both ends of the light shaft 5 passing through and extending out of the side wall of the connecting frame 28. A sleeve is provided on its extended end, and a screw is installed on the sleeve. An extension post is provided on the connecting frame 28 near the screw. The nail and the extension post are connected by a tension spring. A connecting plate is provided on the optical axis, and a peeling plate is mounted on the connecting plate. The peeling plate has a cutting edge at its end and a through groove in the middle. A torsion spring hinge is hinged to one side of the through groove. A blade is provided on the side of the torsion spring hinge near the peeling plate, and it passes through the through groove. The end of the blade away from the torsion spring hinge has a sharp angle. The angle between the blade and the torsion spring hinge is less than 80° to ensure that the torsion spring hinge will not lift up during the cutting process, thus ensuring the depth of the cut. The sharp angle of the blade is... The blade has a slanted edge and a back edge. When cutting the grapefruit peel from bottom to top, the slanted edge touches the peel, while when cutting from top to bottom, the back edge touches the peel, ensuring that it only contacts the surface and not the flesh. This prevents damage to the fruit during peeling. The blade is double-edged with rounded edges, and the cross-section is obtuse. This shape ensures a better fit to the grapefruit's shape, and the rounded edges further enhance its conformity to the grapefruit's shape.

[0038] Specifically, the top of the placement base 26 is provided with several conical tips to ensure that the pomelo is better fixed on the placement base 26.

[0039] The working principle and usage process of this invention: The grapefruit peeling machine described in this invention places the grapefruit on the grapefruit base 9, and then the gripper cylinder 8 grabs it. The push cylinder 7 then pushes it towards the downward blade cutting seat 12 and the upper blade cutting seat 13, causing the grapefruit to be cut at the top and bottom. Simultaneously, the grapefruit peel falls off and enters the storage cavity of the machine housing 6 through the opening and is collected. The grapefruit after being cut at the top and bottom is then grabbed by the gripper cylinder 10. At the same time, the gripper cylinder 8 releases the gripper, and the rotating cylinder 11 begins to rotate, causing the grapefruit to rotate until it is directly above the placement seat 26. Then, the push cylinder 31 starts, causing the rotating cylinder 11 to press downwards, pressing the grapefruit onto the placement seat 26. The motor then starts and rotates six times, simultaneously bringing the grapefruit peel into contact with the peeling blade 27. This is achieved by the interaction of the swing cylinder 19 and the push-blade cylinder 30. The peeling device works in conjunction with the fixing device to peel the grapefruit peel from bottom to top. The sharp edge of the blade touches the grapefruit peel and cuts it. By cutting it multiple times, the grapefruit peel is evenly divided. Then, the peeling device continues to work with the fixing device to peel the grapefruit peel from top to bottom. The edge of the peeling plate contacts the grapefruit peel and begins to peel. The sleeve is pulled close to the extension column by the tension spring, so that it peels the grapefruit peel. The tension of the tension spring needs to be adjusted to ensure that the peeling plate can keep close to the grapefruit pulp. Then, when the peeling device moves downward, the sharp edge of the blade touches the grapefruit peel, so that it can only contact the grapefruit peel and not the grapefruit pulp. This achieves the effect of not damaging the pulp when peeling. By peeling multiple times, the grapefruit peel is completely peeled off. The peeled grapefruit is picked up by the gripper cylinder 210 and placed in the corresponding area. The grapefruit peeling is now complete.
