It should be noted that the specific structure of the cutting device 1 of the present invention is not limited, as long as the annular gap 51 can be cut at the position between the two ends of the coconut shell.

As a preferable mode, on the basis of the above-described embodiment, the cutting device 1 mainly includes the upper platen 11, the lower platen 12, the first elevation driving mechanism 13, the first rotation driving mechanism 14, the cutting mechanism 15, and the like.

Specifically, the upper platen 11 and the lower platen 12 are disposed opposite to each other, and at least one of the upper platen 11 and the lower platen 12 is connected to the first elevation driving mechanism 13, so that the first elevation driving mechanism 13 drives the upper platen 11 and/or the lower platen 12 to be elevated to move the upper platen 11 and the lower platen 12 closer to or away from each other.

It should be noted that, in the initial state, there is enough clearance between the upper platen 11 and the lower platen 12 to facilitate the transportation device 4 to transport the coconut 5, and when the coconut 5 is transported to the right position, the upper platen 11 and the lower platen 12 are moved close to clamp the coconut 5 by the action of the first lifting driving mechanism 13.

In addition, one of the upper platen 11 and the lower platen 12 is connected to a first rotary drive mechanism 14, and the other is movable in the circumferential direction. That is, one of the upper pressing plate 11 and the lower pressing plate 12 is driven by the first rotary driving mechanism 14 to rotate, so as to drive the coconut 5 to rotate, and at this time, the other of the upper pressing plate 11 and the lower pressing plate 12 rotates along with the rotation of the coconut 5 under the friction force of the coconut 5.

That is, the cutting device 1 controls the first lifting driving mechanism 13, the first rotary driving mechanism 14 and the cutting mechanism 15 to move in order through the control device, so that the first lifting driving mechanism 13 drives the upper platen 11 and/or the lower platen 12 to lift, and the coconut 5 is clamped by the upper platen 11 and the lower platen 12; one of the upper pressure plate 11 and the lower pressure plate 12 is driven by the first rotary driving mechanism 14 to drive the coconut 5 to rotate, and the other of the upper pressure plate 11 and the lower pressure plate 12 can move along the circumferential direction, so that the coconut 5 can rotate along with the rotation of the coconut 5 in the rotation process of the coconut 5, and the coconut 5 is driven to rotate while the coconut 5 is clamped by the upper pressure plate 11 and the lower pressure plate 12; and cuts the coconut 5 during the rotation of the coconut 5 using the cutting mechanism 15, thereby cutting an annular gap 51 between both ends of the coconut 5.

It should be noted that the present invention does not limit the specific structure of the first lifting driving mechanism 13, as long as it can drive the upper platen 11 and/or the lower platen 12 to lift.

For example, as shown in fig. 4, preferably, the first elevation driving mechanism 13 includes a linear driving member 131, a mounting plate 132 connected to an output end of the linear driving member 131, and a supporting rod 133 for setting the lower platen 12, and the supporting rod 133 is fixed to the mounting plate 132 by a locking support 134.

In view of the simplicity of the structure, the lower platen 12 is connected to the first elevation drive mechanism 13 on the basis of the above-described embodiment.

That is, the lower pressing plate 12 in this embodiment is close to or far from the upper pressing plate 11 under the action of the first lifting driving mechanism 13, and the upper pressing plate 11 has a limiting effect on the coconut 5, that is, the first lifting driving mechanism 13 drives the lower pressing plate 12 to move to a position where the coconut 5 abuts against the upper pressing plate 11.

It should be noted that, preferably, the conveying device 4 is provided with a carrier 41, the coconut 5 is placed on the carrier 41, when the conveying device 4 drives the carrier 41 to move to a position aligned with the lower platen 12, as shown in fig. 2, the lower platen 12 is located below the carrier 41, at this time, the lower platen 12 is driven to ascend by the first elevating driving mechanism 13, so that the lower platen 12 moves to the bottom of the coconut 5, and the lower platen 12 continues to move in a direction close to the upper platen 11 after picking up the coconut 5.

On this basis, the upper platen 11 is connected to the first rotary drive mechanism 14 in view of the convenience of arrangement.

That is, the upper platen 11 drives the coconut 5 to rotate under the action of the first rotary driving mechanism 14; correspondingly, the lower pressure plate 12 can move along the circumferential direction, and the lower pressure plate 12 can follow the rotation of the coconut 5 during the rotation of the coconut 5.

In order to ensure that lower pressure plate 12 follows the rotation of coconut 5 and that lower pressure plate 12 is connected to first lift drive 13, lower pressure plate 12 is connected to the output end of first lift drive 13 via bearing 16, in the embodiment described above.

It will be appreciated that axial restraint of bearing 16 and lower platen 12 relative to the output of first lift drive mechanism 13 may be achieved by an axial restraint structure.

For example, as shown in fig. 4, the supporting rod 133 is provided with a shoulder for axially limiting one end of the bearing 16, the end of the supporting rod 133 is provided with a limiting fastener 137, and a gasket or the like may be disposed between the limiting fastener 137 and the lower platen 12 to axially limit the lower platen 12 through the end surface of the limiting fastener 137.

Preferably, the output end of the first rotary driving member is connected with a speed reducing mechanism, and the upper pressure plate 11 is fixedly connected with the output shaft of the speed reducing mechanism.

It can be understood that, in general, the coconuts 5 have different sizes and are not uniform in size, and in order to ensure the position of the annular gap 51, for example, to make the annular gap 51 located at the center of each coconut 5, on the basis of the above embodiment, a detection device for detecting the size of the coconut 5 is further included, when the lower platen 12 is connected to the first elevation driving mechanism 13, the second elevation driving mechanism 17 is connected to at least one of the upper platen 11 and the cutting mechanism 15, and the second elevation driving mechanism 17 and the detection device are respectively connected to the control device, so that the control device controls the second elevation driving mechanism 17 to operate according to the detection result of the detection device to position the upper platen 11 and/or the cutting mechanism 15, so that the cutter of the cutting mechanism 15 is aligned with the preset position of the coconut 5 after the coconut 5 is clamped.

That is, the present embodiment controls the second lifting/lowering driving mechanism 17 by the control device to adjust the relative position of the cutting mechanism 15 and the upper platen 11, so as to ensure that the first knife 151 of the cutting mechanism 15 is aligned with the preset position of the coconut 5.

That is, the present embodiment can finely adjust the relative positions of the first cutter 151 of the cutting mechanism 15 and the coconuts 5 according to the size of each coconut 5 so that the first cutter 151 is always aligned with a predetermined position, for example, the middle portion of each coconut 5, that is, the annular slit 51 is located at the middle portion of each coconut 5.
