[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 10In an embodiment of the present invention, an automatic loading and unloading device comprises a loading box 1, at the bottom of which two material pipe assemblies 2 are arranged; the material pipe assembly 2 comprises a feeding pipe 21, the lower end of which is rotatably connected to a guide material pipe 27; the lower end of the guide material pipe 27 is slidably connected to a guide ring, a corrugated material pipe 26 is fixed to the outer side of the guide ring through a clamp 212, and a lifting plate 25 is installed at the upper end of the corrugated material pipe 26 through a rotating ring 211; a material pipe elbow 213 is fixedly installed at the bottom of the corrugated material pipe 26 through a clamp 212;

[0041] The lifting plate 25 is connected to a steel wire rope 24 via a U-shaped buckle, and the upper end of the steel wire rope 24 is connected to a winch 23; the winch 23 is fixedly mounted on a fixed platform 22, and the fixed platform 22 is welded to the feed pipe 21 via a plurality of ribs.

[0042] By adopting the above technical solution, when in use, the material to be added is transported to the feeding box 1 through the wind conveyor for storage. When adding material is needed, the driving crane is moved to the designated position, and the corresponding material pipe assembly 2 is selected according to the material to be added for unloading.

[0043] The winch 23 is activated to unwind the wire rope 24, and under the weight of the corrugated material tube 26 itself, the lifting plate 25 is driven to slide downward along the guide material tube 27 until the elbow 213 of the material tube is aligned with the feeding port, thereby realizing the feeding of the production equipment.

[0044] More specifically, a rotating motor 210 is also fixed on the fixed platform 22, and the output shaft of the rotating motor 210 extends to the bottom of the fixed platform 22 and is equipped with a gear 29; the gear 29 is meshed and connected with a gear ring 28, wherein the gear ring 28 is equipped with the upper end of the guide material tube 27.

[0045] By adopting the above technical solution, when feeding, in order to ensure the accuracy of the material pipe elbow 213 and the material receiving port of the processing equipment, the rotating motor 210 drives the gear 29 to rotate, and with the cooperation of the gear ring 28, the guide material pipe 27 is rotated. Since a plurality of raised slide bars are arranged around the guide material pipe 27, and a plurality of slide grooves are provided on the inner side of the guide ring to cooperate with and slide with the slide bars, when the guide material pipe 27 rotates, the corrugated material pipe 26 and the material pipe elbow 213 can be driven to rotate, thereby adjusting the direction of the material pipe elbow 213 to ensure the accuracy of feeding;

[0046] In addition, since the lifting plate 25 is rotatably connected to the corrugated material tube 26 via the rotating ring 211, the lifting and rotating movements of the entire material tube assembly 2 do not interfere with each other, thereby improving the mobility and flexibility of the material tube assembly 2 in unloading materials.

[0047] In this embodiment, the feeding box 1 has a partition inside, and the two sides of the partition are material storage cavities; the bottom of each storage cavity is conical and a material pipe assembly 2 is installed in conjunction with it; a feeding port 5 is provided at the top of each storage cavity.

[0048] By adopting the above technical solution, two kinds of materials can be stored, and when adding materials, the materials to be added can be selected according to the needs.

[0049] In this embodiment, the feeding box 1 is fixedly mounted on a traveling trolley 10, and guardrails are provided on both sides of the traveling trolley 10;

[0050] An inspection platform 11 is provided below the traveling trolley 10 , and the inspection platform 11 is fixedly connected to the traveling trolley 10 via a plurality of C-shaped steels.

[0051] By adopting the above technical solution, the lubrication of the wire rope and the repair and maintenance of the equipment are facilitated, and the guardrail plays a protective role for the maintenance personnel.

[0052] In this embodiment, the running wheels on both sides of the running trolley 10 run on the tracks on the main beam 12 and the auxiliary beam 14 respectively; the two ends of the main beam 12 and the auxiliary beam 14 are fixedly mounted on the end beam trolley 15;

[0053] A guardrail 13 is fixedly installed on the outer side of the main beam 12 , and a control room 16 is provided on the inner side of the guardrail 13 , and the control room 16 is fixed on the main beam 12 .

[0054] By adopting the above technical solution, the traveling trolley 10 can move along the tracks on the main beam 12 and the secondary beam 14; the end beam trolley 15 moves along the slide rails on both sides of the factory building, thereby realizing the overall movement of the traveling crane, so as to facilitate the loading and unloading of materials in the loading box 1.

[0055] In this embodiment, a cyclone centrifuge 3 is provided on both sides of the feeding box 1, the air inlet end of the cyclone centrifuge 3 is connected to the upper end of the feeding box 1, and the bottom port of the cyclone centrifuge 3 is connected to the lower end of the feeding box 1 through a pipeline; the air outlet at the top of the cyclone centrifuge 3 is connected to a centrifugal fan 4.

[0056] Since there is a certain amount of gas when the gas material conveyor is conveying materials, when the material mixed gas enters the inside of the feeding box 1, material return will occur, resulting in powder diffusion during feeding, causing a large amount of material to be wasted.

[0057] By adopting the above technical solution, when feeding into the feeding box 1, the centrifugal fan 4 is turned on. When the material is filled into the feeding box 1, the internal air will be squeezed outward, and the air mixed with the material enters the cyclone centrifuge 3 under the extraction of the centrifugal fan 4. Under the action of the cyclone centrifuge 3, the material settles downward and re-enters the feeding box 1, while the clean air is extracted by the centrifugal fan 4, thereby avoiding the situation of material return during feeding, and greatly improving the cleanliness of the work site.

[0058] In this embodiment, the upper end and the lower end of one side of the feeding box 1 are respectively threadedly connected with an upper material level sensor 6 and a lower material level sensor 7; the probes of the upper material level sensor 6 and the lower material level sensor 7 extend into the storage cavity inside the feeding box 1;

[0059] The upper material level sensor 6 is electrically connected to the full material warning light 8; the lower material level sensor 7 is electrically connected to the short material warning light 9; the full material warning light 8 and the short material warning light 9 are fixed on the guardrail outside the walking trolley 10, wherein the full material warning light 8 is located above the short material warning light 9.

[0060] By adopting the above technical solution, when adding materials, the upper material level sensor 6 senses the material. When the material level reaches a certain level, the upper material level sensor 6 is sensed and transmits a photoelectric signal to the full material warning light 8. At this time, the full material warning light 8 lights up and the feeding device can be stopped.

[0061] When unloading materials into the production equipment, when the material level is low and the material level sensor 7 cannot sense the material level, the material level sensor 7 transmits a photoelectric signal to the material shortage warning light 9, and the material shortage warning light 9 lights up at this time to remind the staff to add materials to the feeding box 1.

[0062] In this embodiment, a travel switch 214 is fixedly mounted on the bottom of the fixed platform 22 , and the movable contact of the travel switch 214 is located below the gear ring 28 and the gear 29 .

[0063] By adopting the above technical solution, the travel switch 214 can limit the rising degree of the corrugated material tube 26 to avoid the situation of excessive rising and hitting the top, and prevent the lifting plate 25 from colliding with the gear ring 28.

[0064] In this embodiment, a discharge valve 215 is fixedly installed on the top of the discharge pipe 21; the upper end of the discharge valve 215 is fixedly connected to the charging box 1; the discharge valve 215 adopts a ZXF-01CS pneumatic bell-type discharge valve.

[0065] The setting of the discharge valve 215 greatly facilitates the opening and closing control during discharge.

[0066] The working principle is: when in use, the material to be added is conveyed to the feeding box 1 through the wind conveyor for storage. Since the gas material conveyor will have a certain amount of gas when conveying the material, when the material mixed gas enters the inside of the feeding box 1, the material will be returned, resulting in powder diffusion during feeding, causing a large amount of material to be wasted; for this reason, when we add material to the feeding box 1, the centrifugal fan 4 is turned on, and when the material is filled into the feeding box 1, the internal air will be squeezed out, and the air mixed with the material enters the cyclone centrifuge 3 under the extraction of the centrifugal fan 4. Under the action of the cyclone centrifuge 3, the material settles downward and re-enters the feeding box 1, and the clean air is extracted by the centrifugal fan 4, thereby avoiding the situation of material return during feeding, greatly improving the cleanliness of the work site. The material level sensor 6 senses the material. When the material level reaches a certain level, the material level sensor 6 is sensed and transmits a photoelectric signal to the full material warning light 8. At this time, the full material warning light 8 lights up and the feeding device can be stopped.

[0067] When it is necessary to add materials, the crane is moved to the designated position, and the corresponding material pipe assembly 2 is selected according to the material to be added to unload the material. The winch 23 is activated to unwind the wire rope 24, and under the weight of the corrugated material pipe 26, the lifting plate 25 is driven to slide downward along the guide material pipe 27 until the elbow 213 of the material pipe is aligned with the feeding port, thereby realizing the feeding of the production equipment.

[0068] During feeding, in order to ensure the accuracy of the material pipe elbow 213 and the material receiving port of the processing equipment, the rotating motor 210 drives the gear 29 to rotate, and with the cooperation of the gear ring 28, the guide material pipe 27 is rotated. Since the guide material pipe 27 is provided with a plurality of raised slide bars around it, and the inner side of the guide ring is provided with a plurality of slide grooves that cooperate with the slide bars and are slidably connected, when the guide material pipe 27 rotates, it can drive the rotation of the corrugated material pipe 26 and the material pipe elbow 213, thereby adjusting the direction of the material pipe elbow 213 to ensure the accuracy of feeding;

[0069] In addition, since the lifting plate 25 is rotatably connected to the corrugated material tube 26 via the rotating ring 211, the lifting and rotating movements of the entire material tube assembly 2 do not interfere with each other, thereby improving the mobility and flexibility of the material tube assembly 2 in unloading materials.

[0070] When the material level is low and the material level sensor 7 cannot sense the material level, the material level sensor 7 transmits a photoelectric signal to the material shortage warning light 9. At this time, the material shortage warning light 9 lights up to remind the staff to add material to the material box 1.

[0071] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
