DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0028] REFERENCE Figures 2-7A nut cutting and opening device includes a cutting mechanism, a base plate 3, and a reciprocating push-pull power source 19 that can drive the base plate 3 to reciprocate below the cutting mechanism, for example, by driving the base plate 3 to reciprocate through a hydraulic cylinder. The base plate 3 has several material grooves 7, and a rotary clamping mechanism is provided on the base plate 3 at the material grooves 7. The rotary clamping mechanism can clamp nut particles, and the nut particles can rotate at a certain angle under the action of external friction. The cutting mechanism includes a rotating shaft 4, which is driven by a rotary power source. A rotary cutter 5 corresponding to the position of the material groove 7 is installed on the rotating shaft 4. A friction ring 6 is fixed to the side of the rotary cutter 5. During the cutting process, the friction ring 6 generates external friction when it contacts the nut particles.

[0029] When this device is working, the rotating clamping mechanism clamps the nut particles in the feed trough 7, and the reciprocating push-pull power source 19 drives the base plate 3 to move towards the cutting mechanism. (Reference) Figure 7 The base plate 3 moves the nuts in the feed trough towards the rotating cutter 5. When the rotating cutter 5 contacts the macadamia nut, it cuts open the shell. Since the friction ring 6 is fixed on the rotating cutter 5, the friction ring 6 rotates with the rotating cutter 5. As the base plate 3 advances, the nut moves to the position of the friction ring 6, and the outer circumference of the nut contacts the friction ring 6. The friction ring 6 applies a frictional force to the nut. Since the nut particles can rotate at a certain angle under the action of external friction, the friction ring 6 will drive the nut particles to rotate at a certain angle. During the rotation of the nut particles, the rotating cutter 5 cuts an arc-shaped opening into the nut particles. This device can cut an arc-shaped opening into the nut particles. Compared with the traditional flat cutting, the opening size of this device is larger, which is convenient for the subsequent processing of the nut particles and for people to open and eat them.

[0030] refer to Figure 2 , Figure 3 The rotary clamping mechanism includes a support plate 12 slidably connected to the base plate 3. The sliding direction of the support plate 12 is perpendicular to the movement direction of the base plate 3. A vertically arranged clamping plate 21 is fixedly connected to the support plate 12. A first clamp 22 is rotatably connected to the side of the clamping plate 21. A first torsion spring is installed between the first clamp 22 and the clamping plate 21. A rotation angle limiting structure is provided between the first clamp 22 and the clamping plate 21. The rotation angle limiting structure can adopt a three-protrusion structure. The first protrusion and the second protrusion are fixed to the clamping plate 21 at a certain angle, and the third protrusion is fixed to the first... When the third protrusion on the chuck 22 contacts the first protrusion, the first chuck 22 is in the initial position. After the first chuck 22 rotates, the third protrusion contacts the second protrusion. At this time, the first chuck 22 reaches the maximum rotation angle. When the first chuck 22 reaches the maximum rotation angle, the nut and the friction ring 6 change from static friction to dynamic friction, that is, the friction ring 6 and the nut slip. The bottom plate 3 is rotatably connected to the second chuck 23 at the position opposite to the first chuck 22 on the inner wall of the material trough 7. One end of the support plate 12 is provided with a sliding control mechanism to control its movement.

[0031] The sliding position of the support plate 12 relative to the base plate 3 is controlled by the sliding control mechanism, the first clamp 22 clamps the nuts when approaching the second clamp 23, and releases the nuts or puts new nuts when moving away from the second clamp 23. During operation, the sliding control mechanism controls the movement of the support plate 12 to make the first clamp 22 and the second clamp 23 clamp the nuts, and the first torsional spring provides a rotating torque, which has two effects, the first effect is to reset the first clamp 22, and the second effect is to prevent the rotating cutter 5 from rotating when it just contacts the nuts, and only when the friction ring 6 contacts the nuts can the nuts rotate by overcoming the torque.

[0032] As an embodiment, the part of the first clamp 22 and the second clamp 23 contacting the nuts is made of rubber material, which increases the friction between the clamp and the nuts and prevents the nuts from rotating relative to the clamp.

[0033] As an embodiment, the friction ring 6 is a rubber ring, which increases the friction on one hand and has elasticity on the other hand, which can improve the adaptability to different fruit diameters.

[0034] Reference Figure 2 、 Figure 3 The sliding control mechanism includes a spring 18, a limiting plate 13 fixed relative to the ground position and located at one end of the support plate 12, and the spring 18 is installed between the support plate 12 and the base plate 3. The spring 18 can exert a spring force to make the end surface of the support plate 12 abut against the limiting plate 13. The side of the limiting plate 13 close to the support plate 12 has a first end surface 11, a second end surface 15, and a first inclined transition surface 14 for connecting the first end surface 11 and the second end surface 15. When the support plate 12 abuts against the second end surface 15, the distance between the first clamp 22 and the second clamp 23 is greater than the diameter of the nut particles, and when the support plate 12 abuts against the first end surface 11, the first clamp 22 and the second clamp 23 clamp the nut particles.

[0035] For example, the spring 18 of the device adopts a thrust spring, which makes the end of the support plate 12 abut against the limiting plate 13 under the action of thrust. The first end surface 11 and the second end surface 15 are in a stepped structure. When the support plate 12 moves to the first end surface 11, the first clamp 22 approaches the second clamp 23. When the support plate 12 moves to the second end surface 15, the spring pushes the support plate 12 to make the first clamp 22 move away from the second clamp 23.

[0036] When the support plate 12 abuts against the second end surface 15, nuts can be put in or nuts cut by the cutter can be taken out by the mechanical hand at this position.

[0037] To reduce friction, a roller is installed at the end of the support plate 12, so that the support plate 12 can generate relative displacement with the limiting plate 13, making the movement of the support plate 12 smoother.

[0038] The area in which the support plate 12 moves on the first end face 11 is defined as the first working area, and the area in which the support plate 12 moves on the second end face 15 is defined as the second working area. The rotary cutter 5 is set in the first working area, and a feeding station for feeding nut particles into the feed trough 7 is set in the second working area.

[0039] As a preferred embodiment, the feed trough 7 has a through-hole structure at the top and bottom. The top surface of the limiting plate 13 abuts against the bottom surface of the base plate 3. The limiting plate 13 has a discharge hole 20 corresponding to the hole position of the feed trough 7. The limiting plate 13 has a third end face 17 on the side near the support plate 12. The second end face 15 is connected to the third end face 17 through the second inclined transition surface 16. The range in which the support plate 12 moves on the third end face 17 is defined as the third working range. When the support plate 12 is in the first working range or the second working range, the discharge hole 20 and the feed trough 7 are misaligned. When the support plate 12 is in the third working range, the discharge hole 20 and the feed trough 7 are connected, and the nut particles in the feed trough 7 can fall downward through the discharge hole 20.

[0040] When the support plate 12 moves to the third working zone along with the base plate 3, the discharge hole 20 on the support plate 12 is connected to the material trough 7 of the base plate 3, and the nuts fall downward through the discharge hole 20.

[0041] The material feeding station is equipped with a robotic arm for feeding or manual feeding.

[0042] Located at the feeding station, a material box 2 is fixed above the base plate 3 and is positioned relative to the ground. The bottom of the material box 2 has a discharge port 1 corresponding to the position of the material trough 7. A material passage gap 24 is left between the bottom surface of the material box 2 and the top surface of the base plate 3. The distance between the first clamp 22 and the second clamp 23 located at the feeding station can only accommodate one nut particle. The nut particles located in the material trough 7 can pass through the material passage gap 24 and pass through the material box 2.

[0043] In specific operation, when the material trough 7 of the base plate 3 is empty and passes through the material box 2, the nut particles in the material box 2 fall into the material trough 7. Due to the reduced height, the nuts in the material trough 7 can pass through the material passage gap 24, while the nuts that do not enter the material trough 7 remain supported on the base plate 3 and will not pass through the material passage gap 24, thus achieving automatic feeding. The material trough containing the nuts moves with the base plate 3 towards the first working area, and opens when it passes the cutting mechanism. Afterwards, the base plate 3, carrying the support plate 12, returns from the first working area to the second working area. Since there are nuts in the trough after the opening, no other nuts will fall in. As the base plate 3 moves from the second working area to the third working area, the discharge hole 20 of the support plate 12 is connected to the material trough 7 of the base plate 3. The nuts fall downwards through the discharge hole 20, thus achieving automatic discharge. Afterwards, the empty material trough 7 repeats the above steps to achieve the entire process of automatic feeding, cutting, and automatic unloading.

[0044] In one implementation, the rotational power source is a rotary motor, and the power output shaft of the rotary motor is connected to the rotating shaft 4 via a transmission connection.

[0045] In another implementation, a gearbox 8 is connected to one end of the rotating shaft 4. A gear 9 is installed on the low-speed end of the gearbox 8, and a rack 10 is provided on the base plate 3. When the base plate 3 reciprocates, it can drive the rotating shaft 4 to rotate rapidly through the rack 10, gear 9, and gearbox 8. The reciprocating push-pull power source 19 drives the base plate 3 to reciprocate. The rack 10 passes through the gear 9 and is accelerated to rotate the rotating shaft 4 under the action of the gearbox 8. The rotation of the rotating cutter 5 is achieved through the movement of the base plate. This device only requires a reciprocating push-pull power source 19 to realize the steps of feeding, cutting, and unloading, and the control logic is simpler.

[0046] refer to Figure 6 The base plate 3 is equipped with a set of material grooves 7 on each side of the cutting mechanism, and each set of material grooves 7 is equipped with a rotary clamping mechanism. With the material grooves, rotary clamping mechanisms and sliding control mechanisms symmetrically arranged on both sides of the cutting mechanism, the base plate 3 can achieve dual-stroke operation, feeding material on one side while cutting on the other side, thus doubling the work efficiency.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes to the technical solution and inventive concept of the present invention within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
