Description

Technical Field

[0001] This invention belongs to the field of material and raw material transfer technology, and in particular relates to an automatic unloading machine for solid raw materials. Background Technology

[0002] In the industrial production and logistics sectors, the demand for automated loading and unloading of solid raw materials is growing. Traditional manual unloading methods are inefficient, labor-intensive, and prone to problems such as cargo spillage and environmental pollution. To address this issue, various forms of automated unloading machines have emerged, which can effectively improve unloading efficiency, reduce labor costs, and lower environmental and production safety risks.

[0003] Although existing automated unloading machines have solved the problem of manual unloading to some extent, they still have some shortcomings. Taking the unloading process of ton bags of solid materials as an example, although the current equipment can crush the ton bags through mechanical cutting structures, the step of manually inserting the bottom of the ton bag into the feeding guide hopper still relies on many manual operation steps, which restricts the overall operating efficiency of the automated unloading machine. Summary of the Invention

[0004] This invention addresses the problem in existing technologies where the bottom of the ton bag still requires manual insertion into the feeding hopper, which relies heavily on manual operations and hinders the overall operating efficiency of automated unloading machines. The invention proposes the following technical solution:

[0005] An automatic unloading machine for solid raw materials, comprising:

[0006] The main frame, lifting drive assembly, bag cutting device, feeding guide hopper, dust removal and separation assembly, and discharge conveying mechanism;

[0007] The feeding guide hopper is coaxially sleeved inside the bag cutting device, and a pneumatic guiding mechanism is provided on its outer side.

[0008] The pneumatic material guiding mechanism includes: a gas generator connected to the outside of the feed hopper;

[0009] Support sleeve for connecting gas generator;

[0010] A rotating sleeve coaxially fitted inside a support sleeve, with multiple cylindrical jet components circumferentially hinged to its top end;

[0011] A rack that meshes with the first gear, the first gear being fixed to a cylinder, and the rack being connected to a lifting ring;

[0012] A drive component connected to the outside of the support sleeve;

[0013] The drive unit synchronously connects the lead screw and the second gear. The second gear meshes with the gear ring of the rotating sleeve. The lead screw is threadedly connected to the pusher.

[0014] The inner side of the lifting ring is provided with a guide groove, and the outer side of the rotating sleeve is provided with a slider.

[0015] The pusher drives the lifting ring to move axially via a support rod, and the lifting ring and the rotating sleeve are rotated in linkage via a guide groove and a slider.

[0016] As a preferred embodiment of the above technical solution, the jetting component is circumferentially hinged to the top of the rotating sleeve via a cylinder, and the jetting component is composed of a hose and a metal air outlet, with its jetting direction facing the center of the bottom end of the ton bag.

[0017] As a preferred embodiment of the above technical solution, the driving component is a bidirectional motor, whose output shaft is coaxially connected to the lead screw and the second gear, for synchronously driving the lead screw to rotate and the second gear to mesh with the gear ring.

[0018] As a preferred embodiment of the above technical solution, the pushing member is supported by circumferentially distributed support rods, the pushing member is connected to a rotating ring by the circumferentially distributed support rods, the rotating ring is coaxially sleeved inside the mounting sleeve, and the mounting sleeve is fixedly connected to a lifting ring.

[0019] As a preferred embodiment of the above technical solution, a cleaning assembly is also included, which includes a vertical jet pipe, an L-shaped jet pipe, and a vertical jet pipe.

[0020] A vertical jet pipe is located at the meshing point of the first gear and rack, and is used to spray gas into the meshing part to remove dust.

[0021] The L-shaped jet pipe is located at the meshing point of the second gear and the gear ring, and is used to spray gas into the meshing part to remove dust.

[0022] A vertical jet pipe is located at the threaded connection between the lead screw and the pusher, and is used to spray gas into the threaded connection to remove dust.

[0023] As a preferred embodiment of the above technical solution, the metal air outlet of the jet component is fixedly connected to the cylinder, and a vertical plate is provided on the outer side of the cylinder, which is connected to the top of the rotating sleeve.

[0024] As a preferred embodiment of the above technical solution, the vertical jet pipe and the support sleeve are connected by a pipe, the vertical jet pipe is located inside the pusher, the L-shaped jet pipe is located outside the support sleeve, and the vertical jet pipe is located above the support sleeve.

Combined with the ton bag's own descent action, the bottom of the ton bag is automatically connected to the feeding guide hopper, eliminating the dependence on manual bagging. This not only reduces the labor intensity of workers, but also avoids bagging deviation caused by individual differences in manual operation. It improves the automation level of the equipment from the core link and improves the working efficiency of the equipment.

[0029] (2) Through the automated bagging mechanism, workers do not need to directly participate in the bagging process, which reduces the chance of contact with dust and heavy objects. This reduces labor intensity and avoids the risk of mechanical injury or dust inhalation caused by improper manual operation, thus improving the safety of the production process.

[0030] (3) Through the coordinated work of various parts such as the pneumatic material guiding mechanism, the bag cutting device, and the dust removal and separation component: the pneumatic material guiding mechanism precisely opens the bottom end of the ton bag and guides it to be fitted onto the feeding guide hopper through the spiral airflow and deflection action of the jet component, thus completing the automatic fitting; subsequently, after the ton bag and the feeding guide hopper have completed the automatic fitting, the bag cutting device precisely cuts the binding rope on the outside of the bottom end of the ton bag to ensure that the material is unloaded smoothly without damaging the feeding guide hopper; the dust removal and separation component works synchronously during the unloading process to effectively collect and treat the generated dust and prevent environmental pollution. This coordinated work realizes the full automation of the ton bag unloading process, which significantly improves the unloading efficiency and safety. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0038] Example 1: This invention provides an automatic unloading machine for solid raw materials, such as... Figures 1 to 5 As shown, it includes: a frame body 1, a lifting 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 guiding mechanism is provided on its outer side; the pneumatic guiding mechanism includes: a gas generator 315 connected to the outer side of the feeding guide hopper 5; a support sleeve 31 communicating with the gas generator 315; a rotating sleeve 32 coaxially sleeved inside the support sleeve 31, the top of which is circumferentially hinged with multiple jet nozzles 33 with cylinders 34; a rack 36 meshing with a first gear 35, the first gear 35... 5 is fixed to the cylinder 34, and the rack 36 is connected to the lifting ring 319; the drive component 312 is connected to the outside of the support sleeve 31; the drive component 312 is synchronously connected to the lead screw 311 and the second gear 313, the second gear 313 meshes with the gear ring 314 of the rotating sleeve 32, and the lead screw 311 is threadedly connected to the push component 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 slider 82; wherein, the push component 310 drives the lifting ring 319 to move axially through the support rod 39, and the lifting ring 319 and the rotating sleeve 32 are rotated and linked through the guide groove 81 and the slider 82.

[0039] In the unloading process of ton bag solid materials, the ton bag is crushed by mechanical cutting structure, but the bottom of the ton bag still needs to be manually put into the feeding guide hopper 5, which still relies on a lot of manual operation steps, which restricts the overall operating efficiency of the automated unloading machine.

[0040] To address this, the pneumatic material guiding mechanism and mechanical transmission are designed in synergy, allowing the connection between the ton bag and the feeding hopper 5 to be completed without manual operation. This process completely replaces the manual bag-fitting operation, reduces manual steps, and solves the efficiency bottleneck caused by reliance on manual labor in the traditional mode, thereby improving the overall working efficiency of the automated unloading machine.

[0041] The automated bagging mechanism eliminates the need for workers to directly participate in the bagging process, reducing their exposure to dust and heavy objects. This not only lowers labor intensity but also avoids the risk of mechanical injury or dust inhalation caused by improper manual operation, thus improving the safety of the production process.

[0042] The pneumatic material guiding mechanism uses the spiral airflow and deflection action of the jet component 33 to precisely open the bottom end of the ton bag and guide it to fit onto the feeding hopper 5, completing the automatic fitting. Subsequently, after the ton bag and the feeding hopper 5 have completed the automatic fitting, the bag cutting device 4 precisely cuts the binding rope on the outside of the bottom end of the ton bag to ensure smooth material unloading without damaging the feeding hopper 5. The dust removal and separation component 6 works synchronously during the unloading process to effectively collect and treat the generated dust and prevent environmental pollution. This collaborative work realizes the full automation of the ton bag unloading process, significantly improving unloading efficiency and safety.

[0043] In use, the ton bag (which is existing technology and will not be elaborated on here) is guided into the frame body 1 by an electric hoist and conveyor belt, and then into the middle of the lifting drive assembly 2. At this time, the electric hoist moves the position of the ton bag downward (towards the ground), so that the bottom end of the ton bag enters the bag cutting device 4 along the lifting drive assembly 2, and enters the outside of the feeding guide hopper 5 along the bag cutting device 4. As the ton bag moves downward (towards the feeding guide hopper 5), the gas generator 315 (specifically an air pump, with a filter screen installed at the air inlet for filtering the gas) generates high-pressure gas. The high-pressure gas enters the support sleeve 31, and then enters the rotating sleeve 32 along the support sleeve 31. Finally, it enters the jetting element 33 (which is composed of a hose and a metal air outlet) along the rotating sleeve 32. At this time, multiple jetting elements 33 initially blow and converge the gas towards the middle of the bottom of the ton bag.

[0044] Then the drive unit 312 starts and runs. When the drive unit 312 (which is a bidirectional motor) runs, it drives the second gear 313 and the lead screw 311 to rotate synchronously. When the second gear 313 rotates, it drives the rotating sleeve 32 to rotate inside the support sleeve 31 through the gear ring 314. When the rotating sleeve 32 rotates, it drives the jetting element 33 to rotate. When the jetting element 33 rotates, it forms a spiral airflow at the bottom of the ton bag. At the same time, when the rotating sleeve 32 rotates, it drives the lifting ring 319 to rotate through the slider 82. When the lifting ring 319 rotates, it drives the mounting sleeve 37 to rotate outside the rotating ring 38, so that the lifting ring 319 rotates synchronously with the rotating sleeve 32.

[0045] Simultaneously, when the lead screw 311 rotates, it drives the pusher 310 to rise around the inner wall of the feed hopper 5 via the thread. When the pusher 310 rises, it drives the rotating ring 38 to rise via the support rod 39. When the rotating ring 38 rises, it drives the lifting ring 319 to rise via the mounting sleeve 37. This causes the lifting ring 319 to rise around the outside of the slider 82 via the guide groove 81, thereby driving the rack 36 to rise. When the rack 36 rises, it is driven to rotate by the meshing of the first gear 35. When the first gear 35 rotates, the cylinder 34 rotates. When the cylinder 34 rotates, it drives the jetting element 33 to deflect outward (from the center of the bottom of the ton bag to the outside). At this time, the bottom of the ton bag opens and closes. When the opening and closing of the bottom of the ton bag is greater than the maximum outer diameter of the inner wall ring of the feed hopper 5, the ton bag continues to descend, so that the bottom of the ton bag is sleeved on the outside of the feed hopper 5. Then, the pressing structure of the feed hopper 5 presses the connection between the bottom of the ton bag and the feed hopper 5, so that the connection between the bottom of the ton bag and the feed hopper 5 is stable.

[0046] Then, the gas generator 315 and the drive unit 312 are turned off. Next, the binding rope on the outside of the bottom of the ton bag is cut by the bag cutting device 4, so that the solid material inside the ton bag enters the feed hopper 5 along the bottom of the ton bag and enters the discharge conveying mechanism 7 along the feed hopper 5. The discharge conveying mechanism 7 transports the material to the remaining steps. At the same time, the dust at the ton bag connection and the outer connection of the feed hopper 5 enters the inner ring of the feed hopper 5 and enters the dust removal and separation component 6 through the pipe for separation.

[0047] Specifically, a lifting drive assembly 2 (composed of a hydraulic telescopic rod and a deflector plate) is installed at the top of the main frame 1. A discharge conveying mechanism 7 (a screw conveyor) is installed in the middle of the main frame 1. A feeding guide hopper 5 (composed of a receiving hopper, a cylinder, and a pressure plate, wherein the receiving hopper is divided into an inner chamber and an outer chamber) is installed at the top of the feeding guide hopper 5. A bag cutting device 4 (ton bag unpacker) is installed at the top of the feeding guide hopper 5. A dust removal and separation assembly 6 (a cyclone separator) is connected to the outside of the feeding guide hopper 5 through a pipe. The main frame 1, the lifting drive assembly 2, the bag cutting device 4, the feeding guide hopper 5, the dust removal and separation assembly 6, and the discharge conveying mechanism 7 are combined to form an automatic raw material unloading machine (the above structure is existing technology and will not be elaborated on here).

[0048] A support sleeve 31 is installed on the inner wall of the feed hopper 5 by screws. The support sleeve 31 is concave in shape, and a rotating sleeve 32 is rotatably connected inside the support sleeve 31. Figure 5 As shown), the top of the rotating sleeve 32 is evenly equipped with air jets 33 along the axis with the axis as the reference point (the initial state of the air jets 33 is towards the center point of the bottom of the ton bag, and the direction of rotation of 45 degrees is perpendicular to the ground (as shown)). Figure 3(As shown) In this state, rotating 90 degrees means blowing away from the center of the bottom of the ton bag. The jet component 33 is composed of a hose and a metal air outlet. Its jet direction is towards the center of the bottom of the ton bag. The hose connects the rotating sleeve 32 and the metal air outlet. The air outlet of the metal air outlet is directed towards the center of the bottom of the ton bag. Cylindrical cylinders 34 are symmetrically welded to the outside of the metal air outlet of the jet component 33. A vertical plate is provided on the outside of the cylinder 34. The vertical plate is connected to the top of the rotating sleeve 32. Figure 3 and Figure 4 As shown), one end of the cylinder 34 is located at one end of the vertical plate and is connected to a first gear 35 via a key. A vertically movable rack 36 is meshed with the outer side of the first gear 35. Multiple racks 36 are welded to the same lifting ring 319, which is slidably connected inside the feed hopper 5. An mounting sleeve 37 is welded to the bottom end of the lifting ring 319, and a rotating ring 38 (as shown) is rotatably connected inside the mounting sleeve 37. Figure 5 (as shown)

[0049] Multiple support rods 39 (set to eight or more) are symmetrically welded at equal intervals around the axis at the bottom end of the rotating ring 38. The same pusher 310 is welded between the bottom ends of the support rods 39. A lead screw 311 is threadedly connected inside the pusher 310. A drive member 312 (a bidirectional motor) is connected to the top surface of the lead screw 311 via a key. A second gear 313 is connected to the top of the drive member 312 via a key. A gear ring 314 is meshed with the outer side of the second gear 313. The gear ring 314 is snapped and installed on the outer side of the rotating sleeve 32, so that the rotating sleeve 32 and the gear ring 314 rotate synchronously.

[0050] The bottom end of the support sleeve 31 is connected to a gas generator 315 (the gas generator 315 is an air pump, the air inlet of the gas generator 315 is equipped with a filter screen, and the air outlet of the gas generator 315 is connected to the support sleeve 31 through a pipe) and the gas generator 315 is installed on the outside of the feed hopper 5 through a mounting base.

[0051] The lifting ring 319 has guide grooves 81 symmetrically spaced circumferentially on its outer side, and a slider 82 is integrally formed on the inner wall of the rotating sleeve 32 at the position inside the guide grooves 81.

[0052] like Figures 2 to 4As shown, the mechanical structure operates using gears and threaded connections. However, some dust is generated after the ton bag is unpacked. This dust falls onto the gears and threaded connections, affecting their operation. Therefore, a cleaning assembly is also included. The cleaning assembly includes a vertical jet pipe 317, an L-shaped jet pipe 316, and a vertical jet pipe 318. The vertical jet pipe 317 is located at the meshing point of the first gear 35 and the rack 36, and is used to spray gas onto the meshing point to remove dust. The L-shaped jet pipe 316 is located at the meshing point of the second gear 313 and the gear ring 314, and is used to spray gas onto the meshing point to remove dust. The vertical jet pipe 318 is located at the threaded connection between the lead screw 311 and the pusher 310, and is used to spray gas onto the threaded connection to remove dust.

[0053] In use, the gas inside the support sleeve 31 enters the L-shaped jet pipe 316 and the vertical jet pipe 318 respectively. At this time, the gas is blown at the meshing point of the second gear 313 and the gear ring 314 and the threaded connection point of the lead screw 311 and the pusher 310. At the same time, the gas inside the rotating sleeve 32 enters the vertical jet pipe 317 and is blown along the vertical jet pipe 317 to the meshing point of the first gear 35 and the rack 36, thereby achieving the purpose of cleaning the meshing connection and the threaded connection.

[0054] Specifically, the vertical jet pipe 318 is snapped into the inside of the pusher 310 and connected to the bottom of the support sleeve 31 through a pipe; the L-shaped jet pipe 316 is integrally formed on the outside of the support sleeve 31 and connected to it; the drive component 312 is fixedly installed on the outside of the L-shaped jet pipe 316 through a mounting base; and the vertical jet pipe 317 is integrally formed on the top of the support sleeve 31 and connected to it.

[0055] Working principle: In actual use, the device guides the ton bag (electric hoist and conveyor belt are existing technologies and will not be elaborated on here) into the upper part of the frame body 1 through the electric hoist and conveyor belt, and into the middle of the lifting drive assembly 2. At this time, the electric hoist moves the position of the ton bag downward (towards the ground), so that the bottom end of the ton bag enters the bag cutting device 4 along the lifting drive assembly 2, and the bottom end of the ton bag enters the inner cavity of the feeding guide hopper 5 along the bag cutting device 4. At this time, as the ton bag moves downward (towards the feeding guide hopper 5), the gas generator 315 generates high-pressure gas when it runs. The high-pressure gas enters the support sleeve 31 through the pipe, and enters the rotating sleeve 32 along the support sleeve 31. Finally, it enters the jet 33 at the top of the rotating sleeve 32. At this time, multiple jets 33 blow out and converge towards the middle of the bottom end of the ton bag in the initial state.

[0056] Then the drive unit 312 starts and runs. When the drive unit 312 runs, it drives the second gear 313 and the lead screw 311 to rotate synchronously. When the second gear 313 rotates, it drives the rotating sleeve 32 to rotate inside the support sleeve 31 through the gear ring 314. When the rotating sleeve 32 rotates, it drives the jetting element 33 to rotate. When the jetting element 33 rotates, it forms a spiral airflow at the bottom of the ton bag. At the same time, when the rotating sleeve 32 rotates, it drives the lifting ring 319 to rotate through the slider 82. When the lifting ring 319 rotates, it drives the mounting sleeve 37 to rotate outside the rotating ring 38, so that the lifting ring 319 rotates synchronously with the rotating sleeve 32.

[0057] Simultaneously, when the lead screw 311 rotates, it drives the pusher 310 to rise around the inner wall of the feed hopper 5 via the thread. When the pusher 310 rises, it drives the rotating ring 38 to rise via the support rod 39. When the rotating ring 38 rises, it drives the lifting ring 319 to rise via the mounting sleeve 37. This causes the lifting ring 319 to rise around the outside of the slider 82 via the guide groove 81, thereby driving the rack 36 to rise. When the rack 36 rises, it is driven to rotate by the meshing of the first gear 35. Since the first gear 35 rotates, the cylinder 34 rotates. The rotation of the cylinder 34 drives the jetting component 33. The bag deflects outward (from the center of the bottom of the ton bag to the outside). At this time, the blowing gas causes the bottom of the ton bag to open and close. During the continuous blowing process, the opening and closing size of the bottom of the ton bag increases. When the opening and closing size of the bottom of the ton bag is greater than the maximum outer diameter of the dividing circle between the inner and outer chambers of the feed guide hopper 5, the ton bag continues to descend, so that the bottom of the ton bag is directly fitted onto the outside of the dividing circle of the feed guide hopper 5. Then, the cylinder of the feed guide hopper 5 drives the pressure plate to compact the ton bag, so that the ton bag and the top of the dividing circle are pressed and sealed, making the connection between the bottom of the ton bag and the feed guide hopper 5 stable.

[0058] Next, the gas generator 315 and the drive unit 312 are turned off. Then, the binding rope on the outside of the ton bag is cut by the bag cutting device 4 (ton bag unpacker), so that the binding part of the ton bag is opened and closed. Then, the solid material inside the ton bag enters the inner cavity of the feeding guide hopper 5 along the bottom of the ton bag, and enters the discharge conveying mechanism 7 along the inner cavity of the feeding guide hopper 5. Then, the material is conveyed to the remaining steps by the discharge conveying mechanism 7. At the same time, the dust at the ton bag connection and the outer connection part of the feeding guide hopper 5 enters the outer cavity of the feeding guide hopper 5, and enters the dust removal and separation component 6 through the pipe for separation.

[0059] During the above process, the gas generator 315 is started intermittently, which intermittently increases the airflow into the dust removal and separation component 6 to prevent dust from clogging the dust removal and separation component 6.

[0060] Furthermore, the vertical jet pipe 317 is used to rinse the connection between the first gear 35 and the rack 36, while the L-shaped jet pipe 316 rinses the connection between the second gear 313 and the gear ring 314, and the vertical jet pipe 318 rinses the connection between the lead screw 311 and the pusher 310, ensuring the cleanliness of each connection and reducing dust interference.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
