[0002] At present, tobacco stations generally collect tobacco after manual grading or intelligent sorting equipment has been used to sort the tobacco. The current intelligent sorting equipment is manually sorted and loaded, and there is no automatic sorting mechanism. At the same time, the incoming large-leaf crops also have different postures, some are large, some are small, some are fully expanded, some are half expanded, and some are not expanded. There is also a serious adhesion phenomenon. Therefore, it is difficult and ineffective to directly use the tobacco sent by tobacco farmers for automatic sorting. The large-leaf crops that have just been baked in the baking room and are loaded in tobacco clips have the characteristics of neat stems and looseness after rehydration, which is conducive to the development of automation. However, such large-leaf crops need to be transported with tobacco clips as carriers, and there is currently no equipment that can automatically sort tobacco clips directly. Utility Model Content

[0037] This device can realize the functions of changing a whole set of large-leaf crops, dividing large-leaf crops into singles, loading large-leaf crops, and reflowing the fixture. The fixture conveying streamline can realize the functions of changing large-leaf crops, dividing large-leaf crops into singles, loading large-leaf crops, and circulating and reflowing self-made fixtures; the active unlocking module can realize the functions of unlocking the whole set of self-made fixtures and changing large-leaf crops; the passive unlocking module can realize the functions of unlocking a single self-made fixture and loading large-leaf crops. The fixture circulation and return line provides the self-made fixture with functions such as guidance and flow line switching; the self-made fixture realizes functions such as clamping of large-leaf crops, and the self-made fixture is a normally closed fixture. During the whole process, it can ensure that large-leaf crops are effectively clamped, and at the same time, there are no redundant cables, which can realize the circular circulation and return of multiple sets of fixtures; the pushing module A realizes the function of splitting the self-made fixture, and then realizes the separation of large-leaf crops; the pushing module B and the pushing module C alternately push the self-made fixture after the splitting to flow on the circulation line, thereby realizing the function of loading large-leaf crops together with the passive unlocking module; the pushing module The cylinder pushes the homemade fixtures on the flow line from the return line through the carrier rotating module B until the whole set of homemade fixtures is filled; the cache synchronous belt module pushes the whole set of homemade fixtures to the cache position after changing the clamps for large-leaf crops, and after the pushing module A separates a group of homemade fixtures, the cache synchronous belt module continues to push the homemade fixtures to the sub-units, and this cycle continues until all homemade fixtures are separated; the return synchronous belt module uses the material shifting block to step by step push the homemade fixtures on the return line through the carrier rotating module A, and transports the homemade fixtures to the carrier rotating module B.

[0038] The action process is:

[0039] The cigarette clips are manually loaded onto the automatic loading device for large-leaf crops. The cigarette clip conveying mechanism conveys the cigarette clips to the preset position through the pulley module and the floating guide wheel module. The cigarette clip floating mechanism is compatible with different cigarette clip thicknesses through the floating device to achieve effective transportation of different cigarette clips. The preset position is provided with a blocking cylinder, and the accuracy is improved by the proximity switch. When the cigarette clip reaches the preset position, the blocking cylinder extends to initially position the cigarette clip, and then the two ends of the cigarette clip are extended and clamped by the clamping cylinder assembly. After the cigarette clip is clamped, it is pushed to the disassembly position in the direction of the cigarette clip disassembly structure through the feeding cylinder assembly.

[0040] After the cigarette clamp is transported to the clamp removal position, the clamp upper frame clamping block of the cigarette clamp removal mechanism is pressed down by the cylinder to buckle the inner side of the cigarette clamp upper frame so that the cigarette clamp is well clamped in the up, down, left and right directions. Then the cigarette clamp lifting mechanism lifts the cigarette clamp to the clamp replacement position. There is a whole set of homemade clamps that have been returned to the bottom of the active unlocking module, which generally has 32 clamps. Therefore, the active unlocking module can be pressed down to open the whole set of homemade clamps in place. At this time, the cigarette clamp is not disassembled, and the tobacco stems of the large-leaf crops in the cigarette clamp are within the clamping range of the homemade clamps. The large-leaf crops separation combing mechanism is activated to divide the large-leaf crops in the cigarette clamp into independent groups, so as to minimize the probability of cross-stalks between groups. Then the active unlocking module retreats to allow the homemade clamps to clamp the tobacco stems. Then the cigarette clip disassembly mechanism is activated, the unlocking cylinder squeezes the lock of the cigarette clip, the lock structure of the upper frame and the lower frame of the cigarette clip is unlocked, and because the clamping block of the cigarette clip upper frame is pressed down by the pneumatic device to buckle the inner side of the cigarette clip upper frame, the disassembly cylinder moves backward, and the cigarette clip upper frame can be pulled open, and the cigarette clip lower frame also retreats with the feeding cylinder, and the cigarette clip is disassembled at this time. Then the large-leaf crops are replaced from the cigarette clip to the self-made clamp. The cache synchronous belt module moves the entire set of self-made clamps to the cache position.

[0041] Afterwards, the cigarette clip removal mechanism will close the cigarette clips that are free of large-leaf crops again (the action of closing the cigarette clips is opposite to the action of opening the cigarette clips, which will not be described here), and push the cigarette clips onto the belt conveyor mechanism; the belt conveyor mechanism will return the empty cigarette clips; after the empty cigarette clips are full, the personnel will be reminded to take and put the cigarette clips.

[0042] At the same time, the clamps in the cache position are separated into singles through the pusher module A, and the whole set of clamps is separated into independent clamps, thereby realizing the separation of large-leaf crops. When separating, the pusher motor A drives the one-way pusher to move through the synchronous belt module A, pushing the single clamp forward to an intermediate position;

[0043] Then, the pusher module B and the pusher module C alternately transport the sorted self-made clamps located in the middle position to the carrier rotating module A through their respective module structures. During this process, the large-leaf crops in the self-made clamps are unlocked by the passive unlocking module and dropped into the intelligent large-leaf crop sorting equipment for sorting. The carrier rotating module A rotates the self-made clamps that have completed the loading of large-leaf crops 180° up and down to the clamp return line, and the return synchronous belt module transports the self-made clamps to the carrier rotating module B; the carrier rotating module B rotates the self-made clamps 180° up and down to the clamp flow line, and the pusher cylinder continuously pushes the self-made clamps to the clamp change position until the entire set of clamps is in place. After the entire set of clamps is in place, the next cycle can be carried out.

[0044] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can modify or deform the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
