[0021] A method for peeling and removing the skin from a pomelo, the method of using the pomelo peeling machine includes the following steps:

[0022] S1: Grapefruits of a certain size are manually placed onto the grapefruit clamping device by hand;

[0023] S2: The pomelo is transported to the pomelo measuring device by the operation of the chain conveyor belt 1 and chain conveyor belt 2, and the pomelo is rotated by the drive device corresponding to the pomelo measuring device to achieve the purpose of measuring the shape of the pomelo, and the pomelo peel cutting knife is controlled to cut the middle of the pomelo.

[0024] S3: The cutting depth of the grapefruit peel cutting knife is controlled by measuring the thickness of the grapefruit peel using a grapefruit measuring device;

[0025] S4: The cut grapefruit is transported to the peel separation device by the operation of chain conveyor belt 1 and chain conveyor belt 2. The grapefruit is rotated by the drive device corresponding to the peel separation device, and the grapefruit pulp is separated from the peel by the operation of the peel separation device.

[0026] S5: The grapefruit, after the pulp and peel have been separated, is transported to the grapefruit end face cutter position by the operation of the chain conveyor belt 1 and chain conveyor belt 2. Under the operation of the drive device corresponding to the grapefruit end face cutter, the grapefruit is rotated and the end face of the grapefruit is cut by the operation of the grapefruit end face cutter.

[0027] S6: When the pomelo is transported to the end of the chain conveyor belts 1 and 2, the pomelo peel is separated from the pulp under the guidance of the peel separation guide rail. At this time, the pulp is discharged from the pulp conveying trough under the action of inertia.

[0028] The technical effects achieved by this invention are as follows:

[0029] This invention fixes the pomelo by inserting the middle part of the larger end of the pomelo against the support pin on the second clamping disc and squeezing the second clamping disc, and then inserting the middle part of the smaller end of the pomelo into the support pin on the first clamping disc. This makes installation convenient and allows multiple people to work simultaneously, ensuring that the machine can operate at full power.

[0030] This invention uses the surface of a pomelo to support a swing plate, causing the swing plate to swing. By using the constant distance between the swing plate and the roller and the swing angle of the torsion sensor, the distance between the point where the pomelo surface contacts the roller and the middle of the pomelo can be calculated. As the pomelo rotates, the overall size of the pomelo can be obtained, thereby enabling the processing of pomelos of different shapes and sizes.

[0031] In this invention, after the grapefruit peel is cut by the grapefruit peel cutter, the gear is rotated by the torsion spring, which in turn moves the peel thickness measuring plate downward. Since the grapefruit peel has a relatively thick and soft outer layer, the peel thickness measuring plate, under the action of the torsion spring, squeezes and cuts the soft outer layer of the grapefruit peel into contact with the hard outer layer of the grapefruit pulp. The thickness of the grapefruit peel is determined by the reading of the torsion angle of the second torsion sensor, thus avoiding damage to the pulp. Attached Figure Description

[0047] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0048] like Figure 1-13As shown, a grapefruit peeling machine includes a chain conveyor belt 1, a chain conveyor belt 2, and a stepper motor 3. The chain conveyor belt 1 and the chain conveyor belt 2 are fixed to the top front and rear sides of the device support frame 10. Multiple equally spaced support plates 11 are fixedly connected to the side of the chain conveyor belt 1, and multiple equally spaced support plates 22 are fixedly connected to the chain conveyor belt 2. The number of support plates 11 and support plates 21 are the same and their positions correspond. The second conveyor belt 2 is synchronously driven by the first stepper motor 3. The middle of both sides of the first chain conveyor belt 1 and the second chain conveyor belt 2 are fixedly connected to the first and second mounting frames 13 and 14, respectively. The right end of the device support frame 10 is fixedly connected to the pulp conveying trough 15. The pulp conveying trough 15 and the pomelo end face cutter 7 are provided with a peel separation guide rail 16. The device support frame 10 is fixedly connected to the drive device 9 at the positions corresponding to the first mounting frame 13, the second mounting frame 14, and the pomelo end face cutter 7.

[0049] The pomelo clamping device 4 is installed on the support plate 11 and the support plate 2 12. The pomelo clamping device 4 is used to clamp both ends of the pomelo.

[0050] The grapefruit measuring device 5 is installed on the top of the mounting frame 13 and is used to measure the shape of the grapefruit.

[0051] A grapefruit peel cutter 8 is installed on top of the mounting frame 13 and is used to cut the grapefruit peel.

[0052] The peel separation device 6 is installed on the upper and lower sides of the mounting frame 14. The peel separation device 6 is used to separate the grapefruit peel from the pulp.

[0053] The grapefruit end face cutter 7 is installed on the chain conveyor belt 1 and the chain conveyor belt 2. The grapefruit end face cutter 7 is used to cut the end face of the grapefruit.

[0054] A method for peeling and removing the skin from a pomelo, the method of using the pomelo peeling machine includes the following steps:

[0055] S1: Grapefruits of a certain size are manually placed on the grapefruit clamping device 4 by hand;

[0056] S2: The pomelo is transported to the position of the pomelo measuring device 5 by the operation of the chain conveyor belt 1 and the chain conveyor belt 2. The pomelo is rotated by the drive device 9 corresponding to the pomelo measuring device 5 to achieve the purpose of measuring the shape of the pomelo, and the pomelo peel cutting knife 8 is controlled to cut the middle of the pomelo.

[0057] S3: The thickness of the pomelo peel is measured by the pomelo measuring device 5 to control the cutting depth of the pomelo peel cutting knife 8;

[0058] S4: The cut grapefruit is transported to the peel separation device 6 by the operation of the chain conveyor belt 1 and the chain conveyor belt 2. The grapefruit is rotated by the drive device 9 corresponding to the peel separation device 6, and the grapefruit pulp is separated from the peel by the operation of the peel separation device 6.

[0059] S5: The grapefruit after the pulp and peel are separated is transported to the grapefruit end face cutter 7 by the operation of the chain conveyor belt 1 and the chain conveyor belt 2. Under the operation of the drive device 9 corresponding to the grapefruit end face cutter 7, the grapefruit is rotated and the end face of the grapefruit is cut by the operation of the grapefruit end face cutter 7.

[0060] S6: When the pomelo is transported to the end of the chain conveyor belt 1 and chain conveyor belt 2 by the operation of the chain conveyor belt 1 and chain conveyor belt 2, the pomelo peel is separated from the pulp under the guidance of the peel separation guide rail 16. At this time, the pulp is discharged from the pulp conveying trough 15 under the action of inertia.

[0061] Furthermore, the two peel separation guide rails 16 are V-shaped and their openings face the pulp conveying groove 15.

[0062] See attached document Figure 4-5 The grapefruit measuring device 5 includes a mounting frame 501, which is fixedly connected to a mounting frame 13. A torsion sensor 502 is fixedly connected to one side of the mounting frame 501. A swing plate 504 is fixedly connected to the rotating end of the torsion sensor 502. A return spring 503 is hinged to one side of the mounting frame 501. The other end of the return spring 503 is hinged to the top of the swing plate 504. A limit groove 506 is provided on one side of the top of the swing plate 504. A limit boss 505 is fixedly connected to the mounting frame 501. The limit groove 506 and the limit boss 505 are correspondingly arranged. A roller 510 is rotatably connected to the end of the swing plate 504 away from the torsion sensor 502.

[0063] A fruit peel thickness measuring plate 507 is slidably connected to the end of the swing plate 504 away from the first torsion sensor 502. The fruit peel thickness measuring plate 507 is perpendicular to the surface of the pomelo. A toothed groove is opened on one side of the fruit peel thickness measuring plate 507, and it meshes with the gear 509 through the toothed groove. A second torsion sensor 508 is fixedly connected to the end of the swing plate 504 away from the first torsion sensor 502. The main shaft of the second torsion sensor 508 is fixedly connected to the gear 509. A torsion spring 511 is sleeved between the gear 509 and the second torsion sensor 508. One end of the torsion spring 511 is engaged with the gear 509, and the other end is engaged with the second torsion sensor 508. The bottom side of the fruit peel thickness measuring plate 507 is an arc surface.

[0064] Furthermore, the 504 plate is normally in a vertical position.

[0065] Furthermore, the torsion sensor 502 has a torsion angle reading of 0° under normal conditions of the pendulum plate 504.

[0066] Furthermore, the return spring 503 is normally in a stretched state.

[0067] According to the above structure, the pomelo surface supports the swing plate 504, causing the swing plate 504 to swing. By the constant distance between the swing plate 504 and the roller 510 and the swing angle of the torsion sensor 502, the distance between the pomelo surface and the roller 510 and the middle of the pomelo can be calculated. The overall size of the pomelo is obtained under the rotation of the pomelo, and the pomelo peel cutting knife 8 is driven to cut synchronously.

[0068] After the grapefruit peel is cut by the grapefruit peel cutter 8, the gear 509 is rotated by the torsion spring 511, which in turn moves the peel thickness measuring plate 507 downward. Since the grapefruit peel has a relatively thick soft outer layer, the peel thickness measuring plate 507 is pressed against the soft outer layer of the grapefruit and comes into contact with the hard outer layer of the grapefruit pulp under the action of the torsion spring 511. The thickness of the grapefruit peel is determined by the torsion angle of the torsion sensor 508.

[0069] See attached document Figure 6 The grapefruit peel cutter 8 includes a mounting frame 3 803, which is fixed to the top of the mounting frame 1 13. A toothed plate 2 802 is slidably connected to the mounting frame 3 803. A cutting blade 801 is fixedly connected to the top of the toothed plate 2 802. A worm gear 804 is rotatably connected to one side of the mounting frame 3 803. The toothed plate 2 802 and the worm gear 804 are connected in a transmission connection. A stepper motor 6 805 is fixedly connected to one side of the mounting frame 3 803. The stepper motor 6 805 is connected in a transmission connection to the worm gear 804 through a grooved transmission belt 2 806.

[0070] According to the above structure, the stepper motor 805 drives the groove transmission belt 806 to work, and further drives the toothed plate 802 to slide up and down on one side of the mounting frame 803, controlling the cutting blade 801 to cut the grapefruit peel, and through data linkage with the grapefruit measuring device 5, damage to the grapefruit pulp is avoided.

[0071] See attached document Figure 7-10The fruit peel separation device 6 includes a second mounting frame 601, which is fixedly connected to a second mounting frame 14. A threaded rod 604 is threadedly connected to the second mounting frame 601, and a guide rod 605 is fixedly connected to the second mounting frame 601. A sliding plate 603 is slidably connected to the end of the threaded rod 604 away from the chain conveyor belt 1. A stepper motor 602 is fixedly connected to the top of the sliding plate 603. The stepper motor 602 is drivenly connected to the threaded rod 604. The sliding plate 603 is slidably connected to the guide rod 605. A support plate 606 is fixedly connected to the end of the threaded rod 604 near the chain conveyor belt 1.

[0072] Based on the above structure, by driving the stepper motor 602 to drive the slide plate 603 to slide up and down under the guidance of the guide rod 605, the purpose of controlling the support plate 606 to move up or down is achieved.

[0073] Guide plates 609 are fixedly connected to both sides of the support plate 606. Guide groove 2 611 and guide groove 1 610 are provided on the guide plate 609. The connection between guide groove 2 611 and guide groove 1 610 is tangent and interconnected. Slider 1 612 is slidably connected inside the support plate 606. Guide shaft rods 618 are fixedly inserted at both ends of slider 1 612. Slider 2 617 is hinged to the guide shaft rod 618 on the side away from guide groove 1 610. Slider 2 617 is threadedly connected to threaded rod 2 616. Stepper motor 3 607 is fixedly connected to one side of the support plate 606. Stepper motor 3 607 is connected to threaded rod 2 616 through grooved transmission belt 1 608. A mounting block 613 is fixedly connected to the top of slider 1 612. Three metal rods 614 are fixedly connected to one side of the mounting block 613. A fruit peel separation block 615 is fixedly connected to the other end of the metal rods 614.

[0074] The peel separation block 615 has a concave arc groove 619 on the side near the chain conveyor belt 1, and a wedge support plate 620 on the side away from the metal rod 614. The concave arc groove 619 is a concave arc surface.

[0075] Furthermore, the guide groove 610 is an arc-shaped groove, with the inner arc-shaped surface facing the grapefruit.

[0076] Furthermore, the metal rod 614 is made of bent metal wire, and its overall shape is U-shaped. The end connected to the peel separation block 615 extends outward in an arc shape, with the inner arc surface facing the grapefruit.

[0077] Furthermore, the wedge-shaped support plate 620 is used to separate the contact surface between the grapefruit peel and the pulp, and the concave arc-shaped groove 619 can fit the surface of the pulp more closely.

[0078] According to the above structure, the driving stepper motor 607 drives the threaded rod 616 to rotate, thereby dragging the slider 612 to slide within the support plate 606. When the slider 612 moves, it is limited by the guide shaft 618 and guided by the guide grooves 610 and 611. One end of the slider 612 is tilted upward under the guidance of the arc groove of the guide groove 610 and moves towards the end face of the pomelo. This allows the peel separation block 615 to be dragged into the groove cut by the pomelo peel cutter 8 and apply a separation force to the junction of the pomelo peel and the pulp. With the bending of the arc surface of the guide groove 610 and the metal rod 614, as well as the reaction force applied by the pomelo peel, the pomelo peel is separated from the pulp. As the pomelo rotates, most of the pomelo peel and pulp are separated.

[0079] See attached document Figure 11 There are two grapefruit end face cutters 7, which are installed on the adjacent sides of the chain conveyor belt 1 and the chain conveyor belt 2 respectively, and their positions correspond to each other. The grapefruit end face cutter 7 includes a slider 3 702 and a stepper motor 4 704. The slider 3 702 is slidably connected to the side of the chain conveyor belt 1. A cutting blade 701 is fixedly connected to the slider 3 702. A toothed plate 1 703 is fixedly connected to one side of the slider 3 702. A gear 2 705 is drivenly connected to the toothed plate 1 703. The stepper motor 4 704 is fixedly connected to the side of the chain conveyor belt 1. The drive end of the stepper motor 4 704 is fixedly connected to the gear 2 705.

[0080] According to the above structure, the stepper motor 704 drives the gear 705 to rotate, which in turn drives the toothed plate 703 to move to one side and drags the cutting blade 701 toward the grapefruit. Under the rotation of the grapefruit, the cross-section of the grapefruit is cut.

[0081] See attached document Figure 12 The driving device 9 includes a guide frame 2 902, a slider 4 903 slidably connected to the guide frame 2 902, a stepper motor 5 901 fixedly connected to one side of the slider 4 903, an active magnetic coupler 904 fixedly connected to the transmission end of the stepper motor 5 901, a reciprocating cylinder 905 fixedly connected to one side of the guide frame 2 902, and the driving end of the reciprocating cylinder 905 fixedly connected to the slider 4 903.

[0082] Furthermore, slider 403 is configured to correspond with driven magnetic coupler 404.

[0083] According to the above structure, when the pomelo is moved to the appropriate position, the reciprocating cylinder 905 drives the active magnetic coupler 904 to correspond with the driven magnetic coupler 404, and the stepper motor 901 drives the driven magnetic coupler 404 to rotate, so as to synchronously drive the pomelo to rotate.

[0084] See attached document Figure 13The pomelo clamping device 4 includes a connecting plate 401 and a guide frame 407.

[0085] According to the above structure, by inserting the middle part of the larger end of the pomelo against the support pin 405 on the second clamping disc 408 and squeezing the second clamping disc 408, and then inserting the middle part of the smaller end of the pomelo into the support pin 405 on the first clamping disc 403, the pomelo is fixed.

[0086] The working principle of this invention is as follows: A pomelo is manually placed on the pomelo clamping device 4. Then, under the operation of the chain conveyor belt 1 and chain conveyor belt 2, the pomelo is moved to the position of the pomelo measuring device 5. The driving device 9 corresponding to the pomelo measuring device 5 rotates the pomelo, thus measuring its shape. The measured data controls the pomelo peel cutting knife 8 to cut a groove in the middle of the pomelo. Finally, the grooved pomelo is transported by the chain conveyor belts 1 and 2. The grapefruit is fed to the peel separation device 6, and driven by the drive device 9 corresponding to the peel separation device 6, the grapefruit pulp is mostly separated from the peel. Then, with the cooperation of the grapefruit end face cutter 7 and the drive device 9, the grapefruit ends are cut. Finally, when the grapefruit is conveyed to the end of the chain conveyor belt 1 and the chain conveyor belt 2, the grapefruit peel is separated from the pulp under the guidance of the peel separation guide rail 16. At this time, the pulp is discharged from the pulp conveying trough 15 under the action of inertia.
