[0034] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] Reference Figure 1-8 ,

[0036] A nut shelling device comprises: a feeding device 1, a workbench 2 and a cutting device.

[0037] The feeding device 1 is used to transport the nuts to be cut to a cutting position. The cutting device is arranged at the cutting position, and the cutting device is used to cut the nuts to be cut.

[0038] The cutting device includes: a laser cutting member 3, a clamping member 4 and a driving member 5. The laser cutting member 3 adopts a laser. The laser cutting member 3 is used to form a cutting spot on the nut to be cut. The laser spot removes material from the shell of the nut to be cut on the nut to be cut, thereby forming a hole in the shell of the nut to be cut. The laser cutting member 3 adopts the existing technology, and the laser cutting member 3 is a laser. The clamping member 4 is used to clamp the nut to be cut and make the nut to be cut located at the cutting position. The clamping device adopts a mechanical claw in this example. The driving member 5 is used to drive the clamping member 4 or the nut to be cut to rotate, so that the cutting spot forms a cutting line on the nut to be cut that wraps the nut to be cut. Since the laser cutting member 3 can form a hole in the shell of the nut to be cut, a cutting line will be formed when the nut to be cut rotates, and then a cutting gap will be formed, so that a cutting gap is formed in the middle of the shell of the nut to be cut, which is convenient for peeling the shell of the nut to be cut on the nut.

[0039] One of the solutions for the driving member 5 is that when the driving member 5 drives the clamping member 4 to rotate, the clamping member 4 adopts a mechanical claw, and the driving member 5 includes a bracket and a first driving motor. The first driving motor is installed on the bracket, and the mechanical claw is connected to the output end of the first driving motor, so that the first driving motor drives the mechanical claw to rotate, thereby realizing that the driving member 5 drives the clamping member 4 to rotate.

[0040] Another solution for the driving member 5 is that, based on the previous solution, when the driving member 5 drives the nut to be cut to rotate, the driving member 5 only drives the nut to be cut to rotate. In this solution, the clamping member 4 still adopts a mechanical claw, and the mechanical claw is rotatably connected to the bracket. The driving member 5 includes: a power structure 51, a driving wheel 52 and a driven wheel 53. The driving wheel 52 and the driven wheel 53 are both in contact with the outer wall of the nut to be cut, and the power structure 51 is used to drive the driving wheel 52 to rotate. The clamping member 4 can rotate around a fixed axis; when the driving wheel 52 and the driven wheel 53 are in contact with the outer wall of the nut to be cut, the center line of the nut to be cut matches the fixed axis. Among them, the power structure 51 adopts a second driving motor. Among them, the driving wheel 52, the driven wheel 53 and the power structure 51 are all installed on a frame. When the clamping member 4 clamps the nut to be cut, the driving wheel 52 and the driven wheel 53 are both pressed against the outer wall of the nut to be cut. Then, when the driving wheel rotates, the friction between the driving wheel and the shell of the nut to be cut can be used to drive the nut to be cut to rotate.

[0041] In this solution, the power structure 51 drives the driving wheel 52 to rotate at a constant speed, and the driving wheel 52 will also drive the nuts to be cut to rotate at a constant speed, so that the nuts to be cut will have a high relative uniform speed relative to the laser spot, and the cutting effect will be better. In another solution, the driving member 5 drives the clamping member 4 to rotate, and the rotation of the clamping member 4 will cause the nuts to be cut to have a constant angular velocity. When the size of the nuts to be cut changes, the linear velocity of the nuts to be cut will change. Therefore, when ensuring that the linear velocity of the nuts to be cut rotates at a constant speed, it is necessary to change the driving speed of the first driving motor for nuts to be cut of different sizes. The use of the driving wheel 52 and the driven wheel 53 can always keep the nuts to be cut of any size at a constant speed using a pre-set driving speed of the first driving motor to make the nuts to be cut rotate.

[0042] Specifically, the feeding device 1 includes: a vibration plate 11, a rotating wheel 12, a connecting frame, a third driving motor 13 and a shifting member 6. A plurality of receiving grooves are provided on the rotating wheel 12. The connecting frame is used to install the rotating wheel 12, and the third driving motor 13 is arranged on the connecting frame and is used to drive the rotating wheel 12 to rotate. The vibration plate 11 is used to convey the nuts to be cut into the receiving grooves of the rotating wheel 12, and then the rotating wheel 12 rotates, and the shifting member 6 drives the clamping member 4 to move to the receiving grooves, and the clamping member 4 clamps the nuts to be cut, and the shifting member 6 moves and resets the clamping member 4, at which time the nuts to be cut clamped on the clamping member 4 abut against the driving wheel 52 and the driven wheel 53. Then the rotation of the driving wheel 52 can drive the nuts to be cut to rotate.

[0043] More specifically, the displacement member 6 includes a moving platform 61, a first guide rail 62, a first slider 63 and a driving cylinder 64. The first guide rail 62 is fixed on the workbench 2, the first slider 63 is slidably connected to the first guide rail 62, and the moving platform 61 is fixed to the first slider 63. The driving cylinder 64 is used to drive the moving platform 61 to move, and the first guide rail 62 and the first slider 63 are suitable for guiding the moving platform 61.

[0044] The laser cutting piece 3 is located above the clamping piece 4 , and the laser cutting piece 3 is fixed to the workbench 2 .

[0045] The shifting member 6 is used to drive the clamping member 4 to move to the receiving groove to clamp the nut to be cut, and then move the clamping member 4 until the nut to be cut is located on the driving wheel 52 and the driven wheel 53.

[0046] The driving wheel 52 and the driven wheel 53 are both covered with rubber sleeves, and the rubber sleeves are used to increase the friction between the driving wheel 52 and the driven wheel 53 and the nuts to be cut.

[0047] Example 2

[0048] The difference from Example 1 is that:

[0049] A threaded portion 54 is formed on the driving wheel 52; the threaded portion 54 is located on the side of the cutting line. The side means that the threaded portion 54 is located on one side of the cutting line, and the threaded portion 54 and the cutting line do not intersect. When the driving wheel 52 abuts against the outer wall of the nut to be cut, the threaded portion 54 abuts against the outer wall of the nut to be cut; when the driving wheel 52 rotates, the threaded portion 54 causes one end of the nut to be cut to be subjected to an external force away from the cutting line. Among them, the driving wheel 52 is used to drive the nut to be cut to rotate one circle, and the diameter of the driving wheel 52 is smaller than the diameter of the nut to be cut. Generally speaking, the driving wheel 52 needs to rotate 2-5 circles for the nut to be cut to rotate one circle, and there will be different numbers of circles according to different types and sizes of nuts. Among them, the pitch of the threaded portion 54 is controlled at 1-2mm. After the nut to be cut rotates one circle, the driving wheel 52 continues to drive the nut to be cut to rotate, so that the threaded portion 54 will completely separate the shell of the nut to be cut. Taking pecans as an example, after laser cutting, although a gap is formed on the shell of the pecan, the shell of the pecan and the flesh of the pecan are also tightly connected together. When eating later, the shell of the pecan and the flesh of the pecan are tightly connected and need to be separated with force, which only reduces the difficulty of peeling, but it is still difficult to peel the shell. Then, after the nut is cut, the driving wheel 52 continues to drive the nut to rotate, and the nut shell can be subjected to a force to move away from each other after the nut shell is cut, so that the pecan shell and the pecan flesh can be directly separated, which is more convenient for shelling.

[0050] In a specific solution, the threaded portion 54 adopts a thread groove or a thread-shaped protrusion. Preferably, a thread-shaped protrusion is adopted. When the threaded portion 54 adopts a thread-shaped protrusion, the threaded portion 54 adopts an elastic rubber material, and the threaded portion 54 is formed on the outer wall surface of the driving wheel 52; when the threaded portion 54 abuts against the outer wall of the nut to be cut, the threaded portion 54 undergoes elastic deformation and completely abuts against the outer wall of the nut to be cut. Among them, a more specific solution is to first form a rigid thread-shaped protrusion on the driving wheel 52, and then set a layer of elastic rubber pad on the thread-shaped protrusion.

[0051] More specifically, two groups of threaded portions 54 are formed on the driving wheel 52; the two groups of threaded portions 54 have opposite rotation directions; when the driving wheel 52 drives the nut to be cut to rotate, both ends of the nut to be cut are subjected to external forces away from the cutting line, so that the shell of the nut to be cut can be separated from the flesh more quickly.

[0052] More specifically, the threaded portion 54 is disposed on the driven wheel 53 , so that the driven wheel 53 is identical to the driving wheel 52 on which the threaded portion 54 is disposed.

[0053] In other embodiments, the driving member 5 further includes an elastic structure 7, and the elastic structure 7 is used to apply an upward force to the driving wheel 52 and the driven wheel 53. The elastic structure 7 includes: a guide rod 71, a first spring 72 and a lifting frame 73. The lifting frame 73 is used to install the driving wheel 52 and the driven wheel 53. One end of the guide rod 71 is fixed to the workbench 2 and the other end is fixed to the lifting frame 73. One end of the first spring 72 abuts against the workbench 2 and the other end abuts against the lifting frame 73. Among them, the guide rod 71 is a telescopic rod, and a plurality of guide rods 71 ​​are provided. Then, when the clamping member 4 moves to the position of the driving wheel 52 and the driven wheel 53 with the nut to be cut, since the position of the nut to be cut is lower than the normal height of the driving wheel 52 and the driven wheel 53, the nut to be cut will first press down the driving wheel 52 and the driven wheel 53, and then the nut to be cut will reach between the driving wheel 52 and the driven wheel 53, and at this time, the nut to be cut will press down the driving wheel 52 and the driven wheel 53, thereby greatly increasing the contact force between the driving wheel 52 and the driven wheel 53 and the nut to be cut. Thereby, the threaded portion 54 on the driving wheel 52 increases the force exerted by the nut shell to move away from each other, making it easier to separate the shell.

[0054] In other embodiments, the clamping member 4 includes: a first clamping structure 41 and a second clamping structure 42. The first clamping structure 41 and the second clamping structure 42 are both rods, and a first card slot is formed in the first clamping structure 41 for one end of the nut to be cut to be embedded; a second card slot is formed in the second clamping structure 42 for the other end of the nut to be cut to be embedded; the first card slot and the second card slot are both used to abut against the outer wall surface of the nut to be cut. The clamping member 4 also includes a mounting frame 43 for mounting the first clamping structure 41 and the second clamping structure 42; a telescopic control member 44 is arranged on the mounting frame 43; the first clamping structure 41 and the second clamping structure 42 are both connected to the mounting frame 43 through the telescopic control member 44; the telescopic control member 44 is used to make the first clamping structure 41 and the second clamping structure 42 form an elastic telescopic gap for both ends of the nut to be cut to move away from the cutting line. Among them, the telescopic control member 44 adopts an elastic rod body, one end of the elastic rod body is connected to the first clamping structure 41, and the other end is connected to the mounting frame 43. An elastic rod body is also provided at the second clamping structure 42, so that the first clamping structure 41 and the second clamping structure 42 can have an elastic telescopic gap away from each other. When the two ends of the nut shell are away from each other, the first clamping structure 41 and the second clamping structure 42 can also be away from each other, and the nut shell can be separated normally. The elastic rod body in this solution adopts a spring telescopic rod, which is a prior art and will not be elaborated.

[0055] In other embodiments, a movable plate 45 is formed on the mounting frame 43, and two movable plates 45 are provided, which are respectively used to connect with the first clamping structure 41 and the second clamping structure 42. A driving screw 46, a screw nut 47, a second guide rail 48 and a second slider 49 are provided on the mounting frame 43. The second guide rail 48 is fixed on the mounting frame 43, the second slider 49 is slidably connected with the second guide rail 48, and the movable plate 45 is fixed with the second slider 49. The driving screw 46 and the screw nut 47 are used to drive the two movable plates 45 to approach and move away at the same time. The cutting line is located in the middle of the two movable plates 45.
