[0030] Example

[0031] Please refer to Figure 1 This embodiment provides a rotary cutting device for embryo tubes, comprising a pair of cutting mechanisms 2. During the cutting operation, the two cutting mechanisms 2 respectively cut the ends of the embryo tube 1. Specifically, the cutting mechanism 2 comprises a base 21, a clamping assembly, a locking assembly, and a cutter assembly 24. The base 21 is provided with a power support roller 211 that supports the embryo tube 1. The power support roller 211 is driven by a motor. Before the cutting operation, the embryo tube 1 is placed on the power support rollers 211 of the two cutting mechanisms 2 using a lifting tool. During the cutting operation, the power support rollers 211 rotate to drive the embryo tube 1 to achieve rotational motion. It should be noted that if the embryo tube 1 is too long, an auxiliary support roller frame 3 is required between the two cutting mechanisms 2 to prevent the embryo tube 1 from falling and deforming due to its own weight. The auxiliary support roller frame 3 is provided with auxiliary rollers to support the embryo tube 1 to facilitate its rotation.

[0032] Please refer to Figure 1-4In this embodiment, the clamping assembly includes a gantry 221 and a translation drive unit. The gantry is slidably connected to the base 21, and the translation drive unit is fixed to the base 21. The translation drive unit can be driven by a pneumatic cylinder, an oil cylinder, or a screw. In this embodiment, the translation drive unit uses a translation cylinder 222, which drives the gantry 221 to move back and forth. Before cutting, the translation cylinders 222 of the two cutting mechanisms 2 are retracted. The embryo tube 1 is placed on the power support rollers 211 of the left and right cutting mechanisms 2 using a lifting tool. The translation cylinders 222 are then extended, and the left and right gantries 221 are moved near the power support rollers 211.

[0033] Please refer to Figure 1-4 In this embodiment, a tube-pressing drive is further provided on top of the gantry 221. This drive can be a pneumatic cylinder, oil cylinder, screw rod, or connecting rod structure. In this embodiment, the tube-pressing drive is a pneumatic cylinder 223. The piston rod of the pneumatic cylinder 223 is mounted with a tube-pressing roller 225 frame 224. The tube-pressing roller 225 frame 224 is equipped with a guide rod that is slidably connected to the gantry 221. The tube-pressing roller 225 is mounted on the tube-pressing roller 225 frame 224. Before cutting, the pneumatic cylinder 223 is initially retracted. When the gantry 221 is moved into position, the pneumatic cylinder 223 extends, driving the tube-pressing roller 225 to contact the embryo tube 1. The tube-pressing roller 225 and the power support roller 211 limit the embryo tube 1 and ensure that the embryo tube 1 can rotate normally.

[0034] In this embodiment, the locking assembly includes a lifting drive unit and a self-aligning locking mechanism. The lifting drive unit is fixed on the gantry 221, the self-aligning locking mechanism is slidably connected to the gantry 221, and the lifting drive unit drives the self-aligning locking mechanism to rise and fall. The lifting drive unit can adopt a cylinder, an oil cylinder, a screw rod or a connecting rod structure, etc. The pipe pressing drive component of this embodiment adopts a lifting cylinder 231. The lifting cylinder 231 is originally in an extended state, so that the self-aligning locking mechanism is in a high position. After the pipe pressing roller 225 presses the pipe, the lifting cylinder 231 retracts, causing the self-aligning locking mechanism to descend so that the self-aligning locking mechanism can clamp the waste.

[0035] Please refer to Figure 2-6In this embodiment, the self-aligning locking mechanism includes a self-aligning frame 232, a tube-clamping cylinder 233, a transmission structure, and a pair of clamping jaws 235. The self-aligning frame 232 is slidably connected to the gantry 221, and the tube-clamping cylinder 233 is hingedly connected to the self-aligning frame 232, allowing the clamping cylinder 233 to rotate when the clamping cylinder 233 is actuated. The transmission structure is mounted on the self-aligning frame 232, and a clamping jaw slide rail is also mounted on the self-aligning frame 232. The two clamping jaws 235 slide along the clamping jaw slide rail. Specifically, the transmission structure includes a Y-shaped transmission member 2341, a first transmission rod 2342, a V-shaped transmission member 2343, a second transmission rod 2344 and a third transmission rod 2345. The Y-shaped transmission member 2341 is arranged on the self-aligning frame 232 through a first rotating shaft, and the first rotating shaft is located on one side of the axis of the tube clamping cylinder 233. The first free end of the Y-shaped transmission member 2341 is connected to the tube clamping cylinder 233, the second free end of the Y-shaped transmission member 2341 is connected to the first transmission rod 2342, the third free end of the Y-shaped transmission member 2341 is connected to the third transmission rod 2345, the V-shaped transmission member 2343 is connected to the self-aligning frame 232 through the second rotating shaft, the first transmission rod 2342 is connected to one end of the V-shaped transmission member 2343, and the other end of the V-shaped transmission member 2343 is connected to a clamping jaw 235 through the second transmission rod 2344, and drives the other clamping jaw 235 to move through the third transmission rod 2345.

[0036] It should be noted that the clamping jaw 235 is equipped with a roller or a bearing. When the clamping jaw 235 clamps the end of the embryo tube 1, the clamping jaw 235 contacts the embryo tube 1 through the roller or the bearing, which can ensure the normal rotation of the embryo tube 1. Moreover, within a certain tube diameter range, the self-aligning locking mechanism can be used to lock embryo tubes 1 of different diameters.

[0037] Please refer to Figure 1 In this embodiment, a self-aligning push plate 237 is also installed on the self-aligning frame 232. When the translation cylinder 222 pushes the left and right gantries 221 toward each other, the embryo tube 1 is automatically adjusted in position through the self-aligning push plates 237 on the left and right sides.

[0038] Please refer to Figure 1-2 In this embodiment, the cutter assembly 24 is mounted on the base 21 and comprises a fixed frame, a base, and a cutter 241. The fixed frame is fixed to the base 21 and equipped with a lifting screw that drives the base up and down. The base is equipped with a base guide rod that is slidably connected to the fixed frame, and the cutter 241 is fixed to the base. The cutter 241 is initially in a low position. Once the embryo tube 1 is pressed and clamped, the cutter 241 rises to a predetermined height and cuts the end of the embryo tube 1.

[0039] The working process of this embodiment is as follows: the embryo tube 1 is placed on the power support roller 211, and then the translation cylinder 222 is extended to move the gantries 221 on the left and right sides to the vicinity of the power support roller 211. When the gantries 221 are moved into place, the tube pressing cylinder 223 is extended to drive the tube pressing roller 225 to abut against the embryo tube 1. The embryo tube 1 is limited by the tube pressing roller 225 and the power support roller 211, and the embryo tube 1 is ensured to rotate normally to prevent movement. After the tube pressing roller 225 has pressed the tube, the lifting cylinder 231 retracts, the self-aligning locking mechanism moves downward, and the tube clamping cylinder 233 is activated, driving the Y-shaped transmission member 2341 to rotate clockwise. The Y-shaped transmission member 2341, via the third transmission rod 2345, drives the right clamping jaw 235 to the left. Simultaneously, the Y-shaped transmission member 2341, via the first transmission rod 2342, drives the V-shaped transmission member 2343 to rotate clockwise. The V-shaped transmission member 2343, via the second transmission member, drives the left clamping jaw 235 to the right. In this way, the left and right clamping jaws 235 clamp the ends of the embryo tube 1. The powered support roller 211 then activates, rotating the embryo tube 1 about its axis. The cutter 241 rises to a preset height and cuts the end of the embryo tube 1. After cutting, the cutter 241 descends back to its original position, the tube pressing cylinder 223 retracts, driving the tube pressing roller 225 away from the embryo tube 1, and the powered support roller 211 stops. The translation cylinder 222 retracts, returning the left and right gantries 221 to their initial positions, facilitating the removal of the cut embryo tube 1. The tube clamping cylinder 233 then operates again, releasing the clamping jaws 235 and releasing the cut tube end waste, which is then removed by the operator. The lifting cylinder 231 is then reset, and the entire machine is reset. Furthermore, the height of the cutter 241 in this embodiment can be adjusted as needed to adjust the cutting feed rate.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
