[0052] When it is necessary to cut the packaging carton, first adjust the forward speed of the conveying roller 32 for conveying the packaging carton according to the cutting demand, and by rotating the hand wheel 372, the hand wheel 372 drives the worm gear 371 to operate on the surface of the cutting seat 21, thereby driving the rotating shaft 37 to rotate inside the transmission seat 33, thereby driving the toggle frame 38 to turn synchronously. As the toggle frame 38 turns, it can drive the positioning slide post 381 to move synchronously, and the tension spring 382 is deformed and generates elastic force. Then, the movement of the positioning slide post 381, with the cooperation of the positioning slide groove 391, can push and pull the toggle ring 39 to drive the speed cone wheel 35 fixed at its end to slide on the surface of the transmission shaft 34. Because the speed cone wheel 35 and the transmission shaft 34 are key-connected, while ensuring power transmission, it can also achieve axial displacement, that is, the two sets of speed cone wheels can be adjusted. The spacing between the cone wheels 35 can change the transmission ratio between the two sets of variable speed cone wheels 35 under the transmission cooperation of the transmission belt 36, so as to realize the stepless speed change between the transmission shaft 34 at the input end and the transmission shaft 34 at the output end. With the subsequent operation of the transmission shaft 34 at the output end, the transmission sprocket 341 can drive the conveying shaft 31 and the conveying roller 32 to operate inside the cutting seat 21. By controlling the transmission ratio range between the two sets of variable speed cone wheels 35, the forward speed of the packaging carton can be adjusted to meet the demand for the rate of conveying the packaging carton by the conveying roller 32, thereby ensuring the automatic and stable conveying of the packaging carton, avoiding the accumulation and blockage of the packaging carton due to the mismatch between the conveying speed and the cutting speed, and eliminating the need for manual intervention in the movement of the packaging carton. While increasing the practicality of the device, the cutting efficiency of the packaging carton is improved.

[0053] After the speed regulation is completed, the roller conveyor 1 is started, and then the packaging carton to be cut is placed on the surface of the roller conveyor 1. The packaging carton is transported by the roller conveyor 1. When the packaging carton is transported to the end of the cutting seat 21, the photoelectric sensor 27 installed at the end of the cutting seat 21 detects the transported packaging carton. When it is judged that the packaging carton is coming, the cutting motor 23 is automatically started, and the cutting motor 23 drives the driving shaft 231 to rotate inside the cutting seat 21, thereby driving the driving eccentric wheel 232 and the transmission sprocket 234 on its surface to operate. Under the transmission of the transmission sprocket 234, it can The driving transmission shaft 34 is rotated to drive the conveying roller 32 to rotate, thereby conveying the packaging carton and immediately changing its forward speed to cooperate with the operating speed of the cutting knife 24 and the trimming knife 25 to complete the cutting operation. With the rotation of the driving eccentric wheel 232, the cutting knife 24 can be driven to reciprocate up and down along the positioning slide rail 1 241 above the cutting table 22 with the cooperation of the transmission connecting rod 233. When the cutting knife 24 contacts the packaging carton, the end of the packaging carton can be cut. With the movement of the cutting knife 24, the trimming knife 25 can be driven to move synchronously, and then the cutting knife 25 can be moved between the connecting frame 251 and the positioning slide rail 2 With the cooperation of the conveyor belt 52, the trimming knife 25 can perform a cutting movement above the cutting table 22, so as to realize synchronous cutting of the edges and corners of the packaging carton, so that each surface of the packaging carton can be cut into a suitable shape at one time, without the need to perform multiple cutting processes on the packaging carton, thereby reducing the workload and improving the production progress and processing efficiency. During this period, as the packaging carton is conveyed by the conveying roller 32, when the packaging carton is conveyed to the bottom of the extrusion plate 29, the extrusion cylinder 28 can be automatically started through the monitoring of the photoelectric sensor 27, and the extrusion cylinder 28 pushes the push slider 281 to slide inside the extrusion seat 26, thereby driving the extrusion plate 29 By moving closer to the surface of the packaging carton, the movement of the extrusion plate 29 can drive the fixed plate 291 to move synchronously, thereby driving the pressure-feeding ball 292 to move toward the packaging carton, and then with the cooperation of the slide bar 293 and the spring 294, the pressure-feeding ball 292 can be made close to the surface of the packaging carton. As the packaging carton moves, under the action of the pressure-feeding ball 292, not only can the surface of the packaging carton be squeezed and smoothed to avoid bending of the packaging carton, but also the friction between the fixed plate 291 and the packaging carton can be reduced, thereby ensuring smooth conveying, facilitating subsequent cutting work, and improving the quality of cutting processing.

[0054] The cut packaging cartons will be continuously conveyed by the roller conveyor 1 to the next process. The cut waste will be automatically bent under the blocking of the guide baffle 49 and the conveying of the conveying roller 32, and will fall from the discharge trough opened inside the cutting seat 21 to the inside of the discharge channel 48, and then slide from the discharge channel 48 to the inside of the discharge hopper 47 and finally fall and discharge. The discharged waste will fall into the inside of the compacting box 42. When the waste accumulates to a certain extent, the discharge hopper 47 is temporarily closed, and then the flip hydraulic cylinder 451 is started. The flip hydraulic cylinder 451 drives the flip box door 45 to flip on the surface of the compacting box 42, and the compacting box 42 and the flip box door 45 can be compacted. 5 is closed, and then the compaction hydraulic cylinder 44 is started, and the compaction hydraulic cylinder 44 pushes the compaction plate 43 to slide inside the compaction box 42, so that the accumulated waste can be compressed and its volume is gradually reduced until it is compacted into blocks, which saves transportation space, facilitates unified collection and processing, and is convenient for workers to carry carton waste. During this period, the movement of the compaction plate 43 can drive the internal storage lever 431 to slide along the surface of the guide slide bar 411. When the storage lever 431 moves to the toggle groove opened at the end of the guide slide bar 411, the storage lever 431 will automatically slide from the inside of the compaction plate 43 under the elastic force of the spring 432. The pressing plate 43 and the receiving lever 431 are pushed to slide in the toggle slot, and then the electric block 413 is driven to move synchronously, and the second spring 414 is squeezed to deform and generate elastic force. When the two sets of electric blocks 413 are in contact with each other, the lifting hydraulic cylinder 462 can be automatically started and the compacting hydraulic cylinder 44 can be temporarily closed. At this time, the lifting hydraulic cylinder 462 pushes the connecting support plate 461 to drive the lifting top plate 46 to slide up inside the compacting box 42 until the lifting top plate 46 is raised to the top of the compacting box 42. Then, by turning on the electromagnet 433, the two sets of electromagnets are After 433 is energized, magnetic force is generated and they attract each other, which can squeeze spring three 432 and drive the storage lever 431 to be stored inside the compacting plate 43, so as to release the obstruction of the movable slider 412. Under the elastic force of spring two 414, the two groups of movable sliders 412 and the power connection block 413 will automatically separate, and then the compacting hydraulic cylinder 44 will continue to push the compacting plate 43 to move, so as to push out the compressed carton waste. Subsequently, the compacting hydraulic cylinder 44, the flipping hydraulic cylinder 451 and the lifting hydraulic cylinder 462 are controlled to reset, and the discharge hopper 47 is opened, so as to continue the collection operation of the carton waste, so that the carton waste can be effectively recycled and processed, and the operation is convenient.
