DETAILED DESCRIPTION

[0016] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the present application will be described clearly and completely below in conjunction with embodiments.

[0017] Embodiment 1: The present application provides a kind of solid raw material automatic unloading machine, as shown in Figures 1 to 5 The automatic unloading machine includes a rack body 1, a jacking drive assembly 2, a bag cutting device 4, a feeding guide hopper 5, a dust removal and separation assembly 6, and a discharge conveying mechanism 7. The feeding guide hopper 5 is coaxially sleeved inside the bag cutting device 4, and a pneumatic guide mechanism is arranged on the outer side of the feeding guide hopper 5. The pneumatic guide mechanism includes a gas generating element 315 connected to the outer side of the feeding guide hopper 5, a support sleeve 31 communicating with the gas generating element 315, a rotating sleeve 32 coaxially sleeved inside the support sleeve 31, a plurality of jet elements 33 with cylinders 34 circumferentially hinged to the top end of the rotating sleeve 32, a rack 36 engaging a first gear 35, the first gear 35 being fixed to the cylinder 34, the rack 36 being connected to a lifting ring 319, a driving element 312 connected to the outer side of the support sleeve 31, the driving element 312 being synchronously connected to a lead screw 311 and a second gear 313, the second gear 313 engaging a gear ring 314 of the rotating sleeve 32, the lead screw 311 being threadedly connected to a pushing element 310. The inner side of the lifting ring 319 is provided with a guide groove 81, and the outer side of the rotating sleeve 32 is provided with a sliding block 82. The pushing element 310 drives the axial movement of the lifting ring 319 through a support rod 39, and the lifting ring 319 and the rotating sleeve 32 are rotationally linked through the guide groove 81 and the sliding block 82.

[0018] In the unloading process of ton-bag solid materials, the ton-bag is broken by a mechanical cutting structure, but the bottom end of the ton-bag needs to be manually sleeved into the feeding guide hopper 5, which still relies on many manual operation steps, restricting the overall operation efficiency of the automatic unloading machine; Therefore, through the cooperative design of the pneumatic guide mechanism and the mechanical transmission, the ton-bag and the feeding guide hopper 5 can be connected without manual operation, which completely replaces the manual bag sleeving operation, reduces the manual steps, solves the efficiency bottleneck caused by relying on manual operation in the traditional mode, and improves the overall working efficiency of the automatic unloading machine; Through the automatic sleeving mechanism, the workers do not need to directly participate in the bag sleeving process, reducing the opportunity of contacting dust and heavy objects, not only reducing the labor intensity, but also avoiding mechanical injury or dust inhalation risk caused by improper manual operation, improving the safety of the production process.

[0019] The pneumatic guide mechanism precisely opens and guides the bottom end of the ton-bag to be sleeved on the feeding guide hopper 5 through the spiral airflow and deflection action of the jet element 33, completing the automatic sleeving. Subsequently, the bag cutting device 4 precisely cuts the binding rope on the outer side of the bottom end of the ton-bag after the automatic sleeving of the ton-bag and the feeding guide hopper 5, ensuring smooth unloading of the material and preventing damage to the feeding guide hopper 5. The dust removal and separation assembly 6 works synchronously during the unloading process, effectively collecting and processing the generated dust to prevent environmental pollution. This cooperative work realizes the full-process automation of ton-bag unloading, significantly improving the unloading efficiency and safety; When in use, the ton bag is guided into the rack body 1 and the middle part of the jacking driving assembly 2 through the electric hoist and the conveying belt (the electric hoist and the conveying belt belong to the prior art and are not described in detail here), and at this time, the ton bag is moved downward (toward the ground) by the electric hoist, so that the bottom end of the ton bag enters the bag body cutting device 4 along the jacking driving assembly 2, and the bottom end of the ton bag enters the outside of the feeding guide hopper 5 along the bag body cutting device 4, at this time, the high-pressure gas is generated when the gas generating part 315 (which specifically belongs to a gas pump, and the gas inlet of the gas pump is provided with a filter screen after installation, for filtering the gas) operates, the high-pressure gas enters the supporting sleeve 31, and then enters the rotating sleeve 32 along the inside of the supporting sleeve 31, and finally enters the gas jet part 33 (the gas jet part 33 is combined by a hose and a metal gas outlet head) along the rotating sleeve 32, at this time, the multiple gas jet parts 33 blow out converging gas to the middle part of the bottom end of the ton bag in the initial state; Then the driving part 312 is started and operates, the driving part 312 (which belongs to a bidirectional motor) drives the second gear 313 and the lead screw 311 to rotate synchronously when operating, the second gear 313 drives the rotating sleeve 32 to rotate in the supporting sleeve 31 through the gear ring 314 when rotating, the rotating sleeve 32 drives the gas jet part 33 to rotate when rotating, the gas jet part 33 forms a spiral gas flow at the bottom end of the ton bag when rotating, and the rotating sleeve 32 drives the lifting ring 319 to rotate through the sliding block 82 when rotating, the lifting ring 319 drives the mounting sleeve 37 to rotate outside the rotating ring 38 when rotating, so that the lifting ring 319 rotates synchronously with the rotating sleeve 32; At the same time, the lead screw 311 drives the pushing part 310 to ascend around the inner wall of the feeding guide hopper 5 through the thread when rotating, the pushing part 310 drives the rotating ring 38 to ascend through the supporting rod 39 when ascending, the rotating ring 38 drives the lifting ring 319 to ascend through the mounting sleeve 37 when ascending, which causes the lifting ring 319 to ascend around the outside of the sliding block 82 through the guide groove 81, thereby driving the rack 36 to ascend, the rack 36 drives the first gear 35 to rotate through the meshing when ascending, and the cylindrical part 34 rotates when the first gear 35 rotates, the cylindrical part 34 drives the gas jet part 33 to deflect outward (deflect outward from the center of the bottom end of the ton bag) when rotating, which causes the bottom end of the ton bag to open and close, and when the opening and closing of the bottom end of the ton bag is greater than the maximum outer diameter of the circular ring of the inner wall of the feeding guide hopper 5, the ton bag continues to descend at this time, so that the bottom end of the ton bag is sleeved outside the feeding guide hopper 5, and then the ton bag is pressed and connected at the connection between the bottom end of the ton bag and the feeding guide hopper 5 through the pressing structure of the feeding guide hopper 5, so that the connection between the bottom end of the ton bag and the feeding guide hopper 5 is stable; Then, the gas generating part 315 and the driving part 312 are closed, and then the binding rope outside the bottom end of the ton bag is cut by the bag cutting device 4, so that the solid material inside the ton bag enters into the feeding hopper 5 along the bottom end of the ton bag, and enters into the discharging conveying mechanism 7 along the feeding hopper 5, and the material is conveyed to the remaining steps by the discharging conveying mechanism 7, while the dust at the ton bag connection and the outer connection part of the feeding hopper 5 enters into the outer circle of the feeding hopper 5, and enters into the dust separation assembly 6 through the pipeline for separation.

A gas generating member 315 (the gas generating member 315 is a gas pump, a filter screen is installed at the gas inlet end of the gas generating member 315, and the gas outlet end of the gas generating member 315 is connected to the support sleeve 31 by a pipeline) is connected to the bottom end of the support sleeve 31 by a pipeline. A guide groove 81 is symmetrically and equidistantly formed in the outer side of the lifting ring 319 in the circumferential direction, and a sliding block 82 is integrally formed on the inner wall of the rotating sleeve 32 at the position inside the guide groove 81. As shown in Figures 2 to 4 The above utilizes a gear and a threaded connection structure to make the mechanical structure run, but part of the dust is generated after the ton bag is unpacked, at this time the dust falls into the gear and the threaded connection position and affects the running, therefore, a cleaning assembly is further included, which includes a vertical air jet pipe 317, an L-shaped air jet pipe 316 and a vertical air jet pipe 318; the vertical air jet pipe 317 is arranged at the meshing position of the first gear 35 and the rack 36 and is used for spraying gas to the meshing position to remove dust; the L-shaped air jet pipe 316 is arranged at the meshing position of the second gear 313 and the gear ring 314 and is used for spraying gas to the meshing position to remove dust; and the vertical air jet pipe 318 is arranged at the threaded connection position of the screw rod 311 and the pusher 310 and is used for spraying gas to the threaded connection position to remove dust.

[0021] In use, the gas in the support sleeve 31 enters the inside of the L-shaped air jet pipe 316 and the vertical air jet pipe 318, at this time the meshing position of the second gear 313 and the gear ring 314 and the threaded connection position of the screw rod 311 and the pusher 310 are blown, and the gas in the rotating sleeve 32 enters the inside of the vertical air jet pipe 317, at this time the meshing position of the first gear 35 and the rack 36 is blown along the vertical air jet pipe 317, thereby achieving the purpose of cleaning the meshing connection and the threaded connection position.

[0022] Specifically, the vertical air jet pipe 318 is clamped inside the pusher 310 and is in communication with the bottom end of the support sleeve 31 through a pipeline, the L-shaped air jet pipe 316 is integrally formed on the outside of the support sleeve 31 and is in communication therewith, the driving member 312 is fixedly installed on the outside of the L-shaped air jet pipe 316 through a mounting seat, and the vertical air jet pipe 317 is integrally formed above the support sleeve 31 and is in communication therewith.

[0023] Working principle: during actual use, the device guides the ton bag into the upper part of the rack main body 1 and the middle part of the jacking drive assembly 2 through the electric hoist and the conveying belt (the electric hoist and the conveying belt belong to the prior art and are not described in detail here). At this time, the electric hoist moves the position of the ton bag downward (toward the ground), and the bottom end of the ton bag enters the bag cutting device 4 along the jacking drive assembly 2 and enters the inner chamber of the feeding guide hopper 5 along the bag cutting device 4. At this time, the high-pressure gas generated by the gas generator 315 runs, enters the support sleeve 31 through the pipeline, and enters the rotating sleeve 32 along the support sleeve 31, and finally enters the air jet 33 inside the top end of the rotating sleeve 32. At this time, multiple air jets 33 blow out in convergence at the middle part of the bottom end of the ton bag in the initial state; Then the driving part 312 starts and runs, and the driving part 312 drives the second gear 313 and the lead screw 311 to rotate synchronously when it runs. The second gear 313 drives the rotating sleeve 32 to rotate inside the support sleeve 31 through the gear ring 314 when it rotates. The rotating sleeve 32 drives the air jet 33 to rotate when it rotates, and the air jet 33 forms a spiral airflow at the bottom end of the ton bag when it rotates. At the same time, the rotating sleeve 32 drives the lifting ring 319 to rotate through the sliding block 82 when it rotates. The lifting ring 319 drives the mounting sleeve 37 to rotate outside the rotating ring 38 when it rotates, so that the lifting ring 319 rotates synchronously with the rotating sleeve 32; At the same time, the lead screw 311 drives the pusher 310 to rise around the inner wall of the feeding guide hopper 5 through the thread when it rotates. The pusher 310 drives the rotating ring 38 to rise through the support rod 39 when it rises. The rotating ring 38 drives the lifting ring 319 to rise through the mounting sleeve 37 when it rises, so that the lifting ring 319 rises around the outside of the sliding block 82 through the guide groove 81, thereby driving the rack 36 to rise. The rack 36 drives the first gear 35 to rotate through the meshing when it rises. Since the first gear 35 rotates when the cylindrical 34 rotates, the cylindrical 34 drives the air jet 33 to deflect outward (from the center of the bottom end of the ton bag to the outside) when it rotates. At this time, the ton bag bottom end is opened and closed by the blowing gas. During the continuous blowing process, the ton bag bottom end opening and closing size becomes larger. When the ton bag bottom end opening and closing size is greater than the maximum outer diameter of the separation circle between the inner chamber and the outer chamber of the feeding guide hopper 5, the ton bag continues to descend at this time, so that the ton bag is directly sleeved outside the separation circle of the feeding guide hopper 5. Then the cylinder of the feeding guide hopper 5 drives the pressing plate to compact the ton bag, so that the ton bag and the top end of the separation circle are tightly sealed, and the connection between the ton bag bottom end and the feeding guide hopper 5 is stable; Then, the gas generating part 315 and the driving part 312 are closed, and then the binding rope outside the ton bag is cut by the bag cutting device 4 (ton bag unpacker), so that the ton bag is opened and closed at the binding position, and then the solid material inside the ton bag enters the inner chamber of the feeding guide hopper 5 along the bottom end of the ton bag, and then enters the inside of the discharging conveying mechanism 7 along the inner chamber of the feeding guide hopper 5, and then the material is conveyed to the remaining steps by the discharging conveying mechanism 7, while the dust at the ton bag connection and the outer connection part of the feeding guide hopper 5 enters the inner chamber of the feeding guide hopper 5, and then enters the dust separation assembly 6 through the pipeline for separation; In the above process, the gas generating part 315 is intermittently started, so that the airflow entering the dust separation assembly 6 is intermittently increased, preventing the phenomenon of dust blockage in the dust separation assembly 6; And the vertical jet pipe 317 is arranged to flush the connection between the first gear 35 and the rack 36, at the same time, the L-shaped jet pipe 316 flushes the connection between the second gear 313 and the gear ring 314, and the vertical jet pipe 318 flushes the connection between the lead screw 311 and the pushing part 310, ensuring the cleanliness of each connection and reducing the interference of dust.
