[0054] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0055] Reference below Figures 1 to 4 An automatic charging system 100 for a smelting furnace 7 according to an embodiment of the present invention is described.

[0056] like Figure 1 As shown, the automatic charging system 100 for the smelting furnace 7 according to the present invention comprises: a raw material box 1, a rotating lifting device 2, an input device 5, a charging device 4, an output device 6 and a removal device 2121.

[0057] Specifically, the raw material box 1 can be formed in a rectangular parallelepiped shape with an open upper side, and the raw material box 1 can be used to hold smelting raw materials.

[0058] The rotary lifting device 2 includes: a placement platform 21, on which a position 211 to be fed and a position 212 to be fed can be formed, both the position 211 to be fed and the position 212 to be fed are suitable for placing the raw material box 1, the position 212 to be fed can be used to place the raw material box 1 after feeding, and the position 211 to be fed can be used to place the raw material box 1 waiting to be fed. Preferably, the rotary lifting device 2 can make the position 212 to be fed and the position 211 to be fed on the placement platform 21 be in a suitable position at each time point during the working process of the automatic feeding system 100.

[0059] The input device 5 can be used to transport the raw material box 1 containing the smelting raw materials to the waiting feeding position 211. The feeding device 4 is configured to be suitable for feeding the raw material box 1 located at the waiting feeding position 211 into the smelting furnace 7, feeding the smelting raw materials in the raw material box 1 into the smelting furnace 7, and then feeding the raw material box 1 to the feeding position 212 of the placement platform 21. For example, the feeding device 4 can first feed the raw material box 1 at the waiting feeding position 211 into the smelting furnace 7, then feed the smelting raw materials in the raw material box 1 into the smelting furnace 7, and finally feed the raw material box 1 to the feeding position 212 of the placement platform 21, thereby completing a complete process of feeding the raw materials in the raw material box 1.

[0060] The removal device 2121 is used to transport the raw material box 1 located at the feeding position 212 to the output device 6 .

[0061] The output device 6 can transport the raw material box 1 after the feeding is completed. It can be understood that the raw material box 1 transported by the output device 6 can be circulated and transported to prepare for the next loading and feeding action.

[0062] According to the automatic feeding system 100 for the smelting furnace 7 of the present invention, the raw material box 1 is input into the waiting feeding position 211 of the placement platform 21 through the input device 5, and then the feeding device 4 can send the raw material box 1 at the waiting feeding position 211 into the smelting furnace 7, and put the smelting raw materials in the raw material box 1 into the smelting furnace 7, and then send the raw material box 1 after feeding to the feeding position 212 of the placement platform 21, and finally the removing device 2121 removes the raw material box 1 after feeding to the output device 6. Therefore, through the cooperation of the rotating lifting device 2, the input device 5, the feeding device 4, the removing device 2121 and the output device 6, the automatic feeding system 100 can automatically and repeatedly complete the process of feeding into the smelting furnace 7, and can achieve uniform distribution, which speeds up the melting speed of the raw materials, reduces the feeding time, shortens the operation cycle of the smelting furnace 7, reduces the consumption of manpower and eliminates safety hazards.

[0063] In some embodiments of the present invention, the position 211 to be fed and the position 212 to be fed are arranged side by side on the placement platform 21, the position 211 to be fed is provided with a receiving rack 2111 for receiving the raw material box 1, and the removal device 2121 is arranged at the fed position 212. Thus, the receiving rack 2111 of the position 211 to be fed can receive the raw material box 1 filled with raw materials inputted by the input device 5 onto the placement platform 21, and the removal device 2121 is arranged at the fed position 212, so that the empty raw material box 1 on the fed position 212 after feeding can be removed from the fed position 212.

[0064] According to some embodiments of the present invention, Figure 2 As shown, the removal device 2121 includes: a fixed bracket 21211, a conveying roller 21212 and a removal driving member, the fixed bracket 21211 is fixed on the placement platform 21, the conveying roller 21212 is rotatably arranged on the fixed bracket 21211, and the removal driving member is connected to the conveying roller 21212 for driving the conveying roller 21212 to rotate. Therefore, the removal device 2121 can conveniently move the raw material box 1 after the feeding is completed in the previous feeding stroke out of the feeding position 212, so as to make room for the raw material box 1 that is about to complete the feeding in the current feeding stroke.

[0065] For example Figure 1As shown, the placing platform 21 is located on the upper side of the lifting mechanism 22, and the feeding position 211 of the placing platform 21 can be provided with a receiving rack 2111, and the receiving rack 2111 can include a plurality of rows of columns spaced apart in the left-right direction, and a plurality of columns in each row of columns can be spaced apart along the front-back direction on the placing platform 21, wherein, optionally, a receiving rack 2111 can be arranged on each of the left and right edges of the placing platform 21, and at this time, the extension directions of the two receiving racks 2111 are parallel to the left and right edges of the placing platform 21.

[0066] like Figure 2 As shown, the fed position 212 of the placement platform 21 can be provided with a removal device 2121, and the removal device 2121 can include a plurality of conveying rollers 21212, and the plurality of conveying rollers 21212 can be two, three, four, five, six or more, and the number of conveying rollers 21212 at the fed position 212 can be reasonably set according to actual conditions, and the plurality of conveying rollers 21212 can all extend in the left-right direction and be arranged at intervals in the front-back direction, wherein the upper end surface of the receiving frame 2111 and the upper end surfaces of the plurality of conveying rollers 21212 can be located in the same horizontal plane, so that the receiving frame 2111 and the conveying rollers 21212 can be at the same height position, thereby facilitating the feeding device 4 to move or place the raw material box 1, avoiding the height difference between the feeding position 211 and the fed position 212, which makes the automatic feeding system 100 more complicated.

[0067] like Figure 1 As shown, according to some embodiments of the present invention, the rotary lifting device 2 may further include: a lifting mechanism 22, the lifting mechanism 22 is connected to the placing platform 21, and the lifting mechanism 22 may be used to drive the placing platform 21 to move between the first position and the second position. Specifically, when the placing platform 21 is located at the first position, the waiting feeding position 211 is arranged side by side with the output end of the input device 5, and the feeding position 212 is arranged side by side with the input end of the output device 6; when the placing platform 21 is located at the second position, the placing platform 21 may be opposite to the feeding device 4. Thus, the raw material box 1 placed on the placing platform 21 may move between the first position and the second position with the placing platform 21 driven by the lifting mechanism 22, thereby realizing the whole process of the raw material box 1 from entering the placing platform 21 to waiting for feeding and then being output from the placing platform 21 after feeding. At the same time, this embodiment provides a lifting mechanism 22 for lifting the placement platform 21, which is also beneficial for rationally arranging the feeding device 4, the input device 5 and the output device 6 in the longitudinal space, realizing the longitudinal utilization of the space and reducing the floor space of the automatic feeding system 100.

[0068] Furthermore, combined with Figure 1The rotary lifting device 2 may further include: a rotating mechanism 23, which is arranged on the lifting mechanism 22, and is connected to the placing platform 21, and is used to drive the placing platform 21 to rotate in a horizontal plane. Therefore, when the rotating mechanism 23 drives the placing platform 21 to rotate, the relative positions between the to-be-fed position 211 and the fed position 212 and the feeding device 4 can be changed, so that the feeding device 4 can move and place the raw material box 1, and the placing platform 21 can be connected to the input device 5 and the output device 6 respectively to transport the raw material box 1.

[0069] Furthermore, the rotating mechanism 23 is a slewing support mechanism driven by hydraulic, pneumatic or motor. The power system of the rotating mechanism 23 can be reasonably selected according to actual conditions. Thus, the rotating mechanism 23 can obtain sufficient power source to drive the rotation of the placement platform 21.

[0070] Reference below Figure 2 The working process of the rotary lifting device 2 of the above embodiment is described.

[0071] like Figure 2 As shown, the lifting mechanism 22 can drive the placement platform 21 to move between the first position and the second position, wherein the first position is located below the second position, that is, the lifting mechanism 22 can drive the placement platform 21 to move between the first position and the second position spaced apart in the vertical direction. The rotating mechanism 23 is disposed between the lifting mechanism 22 and the placement platform 21, and the rotating mechanism 23 can drive the placement platform 21 to rotate in a horizontal plane. Specifically, the rotating mechanism 23 can rotate during the process of the placement platform 21 moving from the first position to the second position and from the second position to the first position, so that the position 211 to be fed and the position 212 to be fed are in appropriate positions at each time node of the automatic feeding system 100, so that the feeding work can be completed smoothly.

[0072] Specifically, when the lifting mechanism 22 drives the placement platform 21 to move between the first position and the second position, it does not change the relative positions of the position 211 to be fed and the position 212 to be fed on the placement platform 21 and the feeding device 4, the input device 5 or the output device 6 in the horizontal projection plane. In the process of the lifting mechanism 22 driving the placement platform 21 to move up and down, the rotating mechanism 23 synchronously drives the placement platform 21 to rotate, for example, the rotating mechanism 23 drives the placement platform 21 to rotate 90 degrees clockwise or counterclockwise in the horizontal plane, at which time, the relative positions of the position 212 to be fed and the position 211 to be fed on the placement platform 21 and the input device 5, the output device 6 or the feeding device 4 change.

[0073] More specifically, in a specific example, during the movement of the placement platform 21 from the first position to the second position, the placement platform 21 will rise along with the lifting mechanism 22. During the movement of the placement platform 21 from the second position to the first position, the placement platform 21 will both descend along with the lifting mechanism 22. While rising or descending, the placement platform 21 will also rotate itself, so as to rotate the fed position 212 and the to-be-fed position 211 on the placement platform 21 to the appropriate positions, respectively, so that the feeding action can be completed smoothly.

[0074] The placing platform 21 is descending from the second position to the first position, and the placing platform 21 is also rotating from the second position to the first position. When the placing platform 21 reaches the first position, the feeding position 211 and the feeding position 212 are arranged side by side in the front-to-back direction, and the feeding position 211 and the output end of the input device 5 are arranged side by side in the front-to-back direction. The raw material box 1 filled with raw materials placed on the input device 5 can be directly input into the feeding position 211 by the input device 5, and the two receiving racks 2111 of the feeding position 211 can support the raw material box 1. At the same time, the feeding position 212 and the input end of the output device 6 are arranged side by side on the left and right, and there is an empty raw material box 1 on the feeding position 212. The empty raw material box 1 is placed at the feeding position 212 after the feeding is completed in the previous feeding stroke, and the empty raw material box 1 can be output from the feeding position 212 to the output device 6 by the conveying roller 21212 on the feeding position 212.

[0075] The placing platform 21 is in the process of rising from the first position to the second position, and is accompanied by its own rotation in the process of rising from the first position to the second position. When the placing platform 21 is in the second position, the waiting feeding position 211 and the fed position 212 are arranged side by side in the left and right directions. At this time, the feeding device 4 can place the empty raw material box 1 that has completed feeding in the previous feeding stroke on the conveying roller 21212 of the removal device 2121 of the fed position 212. Then, the feeding device 4 can be opposite to the raw material box 1 at the waiting feeding position 211 front and back, and prepare to connect the raw material box 1 containing smelting raw materials again to prepare for feeding the raw materials, and the empty raw material box 1 on the conveying roller 21212 will be ready to be conveyed to the output device 6 by the conveying roller 21212.

[0076] like Figure 3As shown, according to some embodiments of the present invention, the feeding device 4 may include: a track 41, a first movable platform 42, and a lifting and feeding assembly 43. Specifically, the track 41 extends in the front-to-back direction; the first movable platform 42 is arranged on the track 41, and the first movable platform 42 can move in the front-to-back direction along the extension direction of the track 41 to adjust the relative distance between the lifting and feeding assembly 43 and the smelting furnace 7, so that the lifting and feeding assembly 43 can extend the raw material box 1 into the smelting furnace 7 for feeding, and take the raw material box 1 out of the smelting furnace 7 after the feeding is completed. The lifting and feeding assembly 43 is arranged on the first movable platform 42, and the lifting and feeding assembly 43 is suitable for being connected to the raw material box 1, and the lifting and feeding assembly 43 can put the smelting raw materials in the raw material box 1 into the smelting furnace 7. Therefore, the feeding device 4 can facilitate the feeding of the raw materials in the raw material box 1 into the smelting furnace 7.

[0077] For example, when feeding, the lifting and feeding assembly 43 is first connected to the raw material box 1, and then the first movable platform 42 moves backward along the track 41, and the lifting and feeding assembly 43 moves backward with the first movable platform 42, and the raw material box 1 is extended into the smelting furnace 7 to complete the feeding, and then the first movable platform 42 can move forward along the track 41, and the lifting and feeding assembly 43 also moves forward with the first movable platform 42, thereby bringing the raw material box 1 that has completed the feeding out of the smelting furnace 7.

[0078] Furthermore, combined with Figure 2 and Figure 3 The feeding device 4 may further include: a rotating platform 44. Specifically, the axis of the rotating platform 44 is along the vertical direction (for example Figure 2 The rotating platform 44 is rotatably arranged on the first movable platform 42 around an axis, that is, the rotating platform 44 is rotatable in a horizontal plane, and the lifting and feeding assembly 43 is fixed on the rotating platform 44, thereby, the rotating platform 44 can drive the lifting and feeding assembly 43 to rotate around the axis of the rotating platform 44.

[0079] Furthermore, combined with Figure 3 The first movable platform 42 may also be provided with a slide rail 421, which extends in the left-right direction ( Figure 3 The feeding device 4 may further include: a second movable platform 45, the second movable platform 45 is movably arranged on the slide rail 421 along the left-right direction, and the rotating platform 44 is rotatably arranged on the second movable platform 45, so that when the second movable platform 45 moves left-right, it can drive the rotating platform 44 to move left-right together, and the lifting and feeding assembly 43 located on the rotating platform 44 can also move left-right accordingly, thereby, the relative position of the lifting and feeding assembly 43 with respect to the smelting furnace 7 in the left-right direction can be conveniently adjusted, so that the lifting and feeding assembly 43 is convenient for putting raw materials into the smelting furnace 7.

[0080] For example, the smelting furnace 7 can be provided with a plurality of feeding ports (for example, two feeding ports) arranged at intervals in the left and right directions. The lifting and feeding assembly 43 is arranged on the second movable platform 45 through the rotating platform 44. When the second movable platform 45 moves left and right, the lifting and feeding assembly 43 can be conveniently moved between the positions directly opposite the plurality of feeding ports so as to respectively feed the smelting raw materials into the plurality of feeding ports.

[0081] Specifically, Figure 3 As shown, when the placing platform 21 is in the second position, the lifting and feeding assembly 43 is first connected to the fully loaded raw material box 1 at the to-be-fed position 211, and then the second movable platform 45 moves to the right along the slide rail 421, and the rotating platform 44 and the lifting and feeding assembly 43 on the rotating platform 44 also move to the right along with the second movable platform 45, until the raw material box 1 is aligned with the right side feeding port of the smelting furnace 7, and then the first movable platform 42 moves backward along the track 41, and the second movable platform 45 moves along with the first movable platform 4 2 moves backward, so that the lifting and feeding assembly 43 can extend the raw material box 1 into the smelting furnace 7 to complete the feeding, and then the first moving platform 42 can move forward along the track 41, and the second moving platform 45 also moves forward with the first moving platform 42, so that the lifting and feeding assembly 43 can take the raw material box 1 that has completed the feeding out of the smelting furnace 7, and then the second moving platform 45 can move leftward along the slide rail 421, so that the lifting and feeding assembly 43 can place the raw material box 1 that has completed the feeding to the feeding position 212 of the placing platform 21.

[0082] Combination Figure 4 When the raw material box 1 is formed as a box body with an opening at the top, the opening side of the raw material box 1 is upward when it is placed on the placement platform 21. When feeding, the raw material box 1 must be turned over to the opening downward so that all the raw materials in the raw material box 1 can be put into the smelting furnace 7. Therefore, in some embodiments, the lifting and feeding assembly 43 may include: a base 431, a feeding rod turning mechanism 432 and a turning drive 433. Specifically, the base 431 is fixed on the rotating platform 44, and the base 431 can be used to install and support the lifting and feeding assembly 43; the feeding rod turning mechanism 432 includes a feeding rod 4321, and the feeding rod 4321 is rotatably arranged on the feeding rod turning mechanism 432 around a horizontal axis, so that the rotatable feeding rod 4321 can drive the raw material box 1 connected thereto to turn over, thereby completing the feeding.

[0083] Furthermore, the free end of the feeding rod 4321 is suitable for being detachably connected to the raw material box 1. For example, when raw materials need to be added, the free end of the feeding rod 4321 can be reliably fixed to the raw material box 1 to complete the feeding process. When the feeding is completed and the empty raw material box 1 is placed at the feeding position 212 of the placement platform 21, the free end of the feeding rod 4321 can be separated from the raw material box 1. In this way, the action of adding raw materials can be repeatedly completed using only one feeding rod 4321.

[0084] The flip driving member 433 is connected to the feeding rod 4321 to drive the feeding rod 4321 to rotate. The flip driving member 433 can provide support for the feeding rod 4321 and can also provide flipping power for the rotation of the feeding rod 4321.

[0085] Furthermore, if Figure 4 As shown, the lifting and feeding assembly 43 may further include a swing mechanism 434, and the swing mechanism 434 includes: a swing frame 4341, a connecting rod mechanism 4342 and a swing driving member 4343. Specifically, the feeding rod flipping mechanism 432 is arranged on the swing frame 4341, the connecting rod mechanism 4342 is hinged between the swing frame 4341 and the base 431, and the swing driving member 4343 is connected to the swing frame 4341 to drive the swing frame 4341 to swing. Furthermore, as Figure 4 As shown, the connecting rod mechanism 4342 is a parallelogram connecting rod mechanism 4342. In this embodiment, the feeding rod flipping mechanism 432 is connected to the connecting rod mechanism 4342 in this embodiment. When the connecting rod mechanism 4342 swings in the plane where it is located (for example, a plane perpendicular to the ground), the feeding rod flipping mechanism 432 is driven to swing synchronously, thereby realizing synchronous movement of the feeding rod flipping mechanism 432 in the up and down directions.

[0086] Specifically, when feeding, the feeding rod 4321 is first connected to the raw material box 1 at the waiting feeding position 211 on the placement platform 21, and then the swing frame 4341 swings upward, so that the feeding rod 4321 can lift the raw material box 1 to the same height as the furnace mouth of the smelting furnace 7 for feeding; after the feeding is completed, the feeding rod 4321 will move the raw material box 1 extended into the smelting furnace 7 out of the furnace mouth, and then the swing frame 4341 swings downward, so that the feeding rod 4321 moves downward to place the empty raw material box 1 after the feeding is completed to the feeding position 212. Therefore, the swing mechanism 434 in this embodiment can overcome the height difference between the placement platform 21 and the furnace mouth of the smelting furnace 7, and help the feeding rod flipping mechanism 432 to repeatedly complete the feeding of raw materials.

[0087] Furthermore, refer to Figure 4 The swing frame 4341 is formed into a plate shape extending substantially in the vertical direction, and the feeding rod turning mechanism 432 is fixed on the swing frame 4341. Specifically, as Figure 4As shown, the swivel support 4322 of the feeding rod flipping mechanism 432 can be fixedly connected to the rear side of the swing frame 4341 by fasteners, the swivel support 4322 can be a support bearing, the flipping drive member 433 can be arranged on the front side of the swing frame 4341, the flipping drive member 433 can be a drive motor, or a hydraulic motor or a pneumatic motor, the swing frame 4341 can be provided with a through hole, the driving shaft of the flipping drive member 433 can pass through the through hole from front to back to drive the feeding rod 4321 to rotate, thereby, the flipping drive member 433 can drive the feeding rod flipping mechanism 432 to rotate, thereby helping the raw material box 1 to put the raw material into the smelting furnace 7.

[0088] Furthermore, if Figure 4 As shown, the connecting rod mechanism 4342 is a parallelogram connecting rod mechanism 4342. Thus, the connection between the feeding rod flipping mechanism 432 and the swinging mechanism 434 can be made more stable, and the parallelogram connecting rod mechanism 4342 is also conducive to realizing the swinging action.

[0089] For example Figure 4 As shown, the front end of the upper connecting rod and the front end of the lower connecting rod of the parallelogram linkage mechanism 4342 can be hinged to the base 431, and the rear end of the upper connecting rod and the rear end of the lower connecting rod can be hinged to the swing frame 4341. The swing driving member 4343 can be formed as a hydraulic cylinder mechanism, and the front end of the swing driving member 4343 is hinged to the lower end of the base 431, and the rear end of the swing driving member 4343 can be hinged to the swing frame 4341, or the rear end of the swing driving member 4343 can also be hinged to the upper connecting rod of the parallelogram linkage mechanism 4342. In this way, the hydraulic cylinder mechanism and the base 43 1 and the swing frame 4341 can rotate relative to each other, the upper connecting rod, the base 431 and the swing frame 4341 can rotate relative to each other, and the lower connecting rod, the base 431 and the swing frame 4341 can rotate relative to each other. Therefore, the telescopic movement of the hydraulic cylinder mechanism can be converted into the swinging of the swing frame 4341 in a vertical plane perpendicular to the ground. At the same time, the swinging of the swing frame 4341 in a vertical plane perpendicular to the ground will be converted into the up and down translation of the feeding rod flipping mechanism 432, so that the feeding rod 4321 can drive the raw material box 1 to move up and down, thereby completing the repeated feeding.

[0090] Combination Figure 3 and Figure 4 According to some embodiments of the present invention, a slot 11 is provided on the outer wall of the raw material box 1, and the slot 11 is arranged along the up-down direction (for example Figure 3The feeding rod 4321 extends in the vertical direction (in the vertical direction), and a block 43211 is provided at the free end of the feeding rod 4321, and the block 43211 is suitable for being inserted into the card slot 11. Therefore, when feeding is required, the feeding rod 4321 can be moved in the vertical direction, for example, the feeding rod 4321 can be moved from top to bottom, so as to insert the block 43211 at the free end of the feeding rod 4321 from top to bottom into the card slot 11, thereby facilitating the plugging of the feeding rod 4321 with the raw material box 1. The matching structure of the block 43211 and the card slot 11 is simple, and plugging and separation are more convenient, and the reliability is high.

[0091] like Figure 4 As shown, according to some embodiments of the present invention, the lifting and feeding assembly 43 may further include a raw material box connecting mechanism 435, which is arranged on the swing frame 4341, and the raw material box connecting mechanism 435 is suitable for locking the raw material box 1 when the feeding rod 4321 is connected to the raw material box 1, thereby preventing the raw material box 1 from falling off the feeding rod 4321 when it enters the smelting furnace 7 and is flipped over.

[0092] Furthermore, combined with Figure 4 , the raw material box 1 may be provided with a plug hole (not shown), and the raw material box connection mechanism 435 may include: a connection rod 4351 and a connection driving member 4352. Specifically, the connection rod 4351 is connected to the swing frame 4341, and the connection rod 4351 can move relative to the swing frame 4341 between the plug position and the free position along the front-back direction; the connection driving member 4352 is provided on the swing frame 4341, and the connection driving member 4352 is connected to the connection rod 4351, and the connection driving member 4352 is used to drive the connection rod 4351 to move between the plug position and the free position. Among them, when the connecting rod 4351 is in the plug-in position, the free end of the connecting rod 4351 is inserted into the socket of the raw material box 1. At this time, the connecting rod 4351 can cooperate with the feeding rod 4321 to lift the raw material box 1 into the smelting furnace 7 to complete the feeding and exit the smelting furnace 7; when the connecting rod 4351 is in the free position, the free end of the connecting rod 4351 is disengaged from the socket of the raw material box 1, and at the same time, the feeding rod 4321 is separated from the empty raw material box 1 after the feeding is completed, and the empty raw material box 1 is placed on the fed position 212 of the placement platform 21.

[0093] Furthermore, combined with Figure 4, the feeding rod 4321 can be a hollow rod, and the raw material box connecting mechanism 435 can also include: a guide limit bracket 4353, the guide limit bracket 4353 is fixed to the inner side of the feeding rod 4321, and a guide limit channel is defined on the guide limit bracket 4353, and the connecting rod 4351 is movably arranged in the guide limit channel. Therefore, the guide limit bracket 4353 in this embodiment can be a moving guide for the connecting rod 4351, so that the connecting rod 4351 can be accurately and automatically connected to the raw material box 1. At the same time, the guide limit bracket 4353 supports the connecting rod 4351 to prevent one end of the connecting rod 4351 from being tilted due to the weight after the connecting rod 4351 is connected to the raw material box 1.

[0094] Furthermore, combined with Figure 4 The guide limit bracket 4353 may include: a plurality of guide plates 43531, each of which extends radially along the feeding rod 4321, and the plurality of guide plates 43531 extends along the length direction of the feeding rod 4321 (for example Figure 4 ) are arranged at intervals, and each guide plate 43531 is formed with a plurality of guide plates 43531 along the thickness direction ( Figure 4 The connecting rod 4351 passes through the through holes of the guide plates 43531 (in the front-to-back direction shown in FIG), and the connecting rod 4351 passes through the through holes of the plurality of guide plates 43531 in sequence. The through holes of the plurality of guide plates 43531 in this embodiment can cooperate with each other to serve as movement guides for the connecting rod 4351, so that the connecting rod 4351 can be accurately and automatically connected to the raw material box 1. At the same time, the plurality of guide plates 43531 jointly support the connecting rod 4351 to prevent one end of the connecting rod 4351 from being tilted due to the weight after the connecting rod 4351 is connected to the raw material box 1.

[0095] In some embodiments, the central axis of the connecting rod 4351 can coincide with the central axis of the feeding rod 4321. In this way, when the connecting rod 4351 and the feeding rod 4321 are both connected to the raw material box 1, if the feeding rod 4321 is turned over to put the raw materials in the raw material box 1, the feeding rod 4321 can avoid interference with the connecting rod 4351 during the rotation process, and the structural arrangement is more compact and reasonable.

[0096] According to some embodiments of the present invention, Figure 1 As shown, the input device 5 and the output device 6 are stepping conveyors or chain conveyors. In this way, it is convenient to control the time interval between two adjacent raw material feeding actions, so as to better control the interval between two adjacent raw material boxes 1 on the input device 5 and the output device 6, and further make the feeding work of the entire automatic feeding system 100 reasonably and orderly and automatically carried out.

[0097] like Figure 2As shown, in some embodiments of the present invention, any one of the input device 5 and the output device 6 may include: a frame 51, a lifting mechanism 52 and a conveying trolley. Specifically, the frame 51 of the input device 5 extends in the front-to-back direction, the lifting mechanism 52 of the input device 5 is arranged on the frame 51, and the conveying trolley of the input device 5 is arranged on the lifting mechanism 52. The lifting mechanism 52 can drive the conveying trolley to move in the up-down direction. Furthermore, when the lifting mechanism 52 drives the conveying trolley to move in the up-down direction at a height exceeding the upper end surface of the frame 51, the conveying trolley moves in the extension direction of the frame 51 (for example, Figure 1 Thus, it is convenient for the conveying trolley to convey the raw material box 1 along the extending direction of the input device 5, and it is avoided that the raw material box 1 and the frame 51 interfere with each other during the conveying process.

[0098] When the input device 5 transports the raw material box 1, the raw material box 1 can be placed on the frame 51 first, for example, the raw material box 1 can be placed on the upper end surface of the frame 51, and then the lifting mechanism 52 can drive the conveying trolley to move upward, and make the height of the conveying trolley gradually approach the upper end surface of the frame 51. When the height of the conveying trolley reaches the upper end surface of the frame 51 and continues to rise, the conveying trolley can lift the raw material box 1 on the frame 51 upward to make it higher than the frame 51. At this time, the conveying trolley can move from front to back, for example, move backward the position of a raw material box 1, and then the lifting mechanism 52 can drive the conveying trolley to move downward again, so that the raw material box 1 on the conveying trolley can fall back to the upper end surface of the frame 51 again. In this way, the raw material box 1 can be gradually transported to the outlet end of the input device 5, and further transported to the placement platform 21, in preparation for the subsequent feeding action.

[0099] Similarly, the frame 51 of the output device 6 extends in the front-to-back direction, the lifting mechanism 52 of the output device 6 is arranged on the frame 51, and the transport trolley of the output device 6 is arranged on the lifting mechanism 52. The lifting mechanism 52 can drive the transport trolley to move in the up-down direction. Further, when the lifting mechanism 52 drives the transport trolley to move in the up-down direction beyond the upper end surface of the frame 51, the transport trolley moves in the extension direction of the frame 51 (for example, Figure 1 The front-to-rear direction shown in FIG. 1 is movable.

[0100] When the output device 6 transports the raw material box 1, the raw material box 1 can be first placed on the frame 51 of the output device 6, for example, the raw material box 1 can be placed on the upper end surface of the frame 51, and then the lifting mechanism 52 can drive the conveying trolley to move upward, and make the height of the conveying trolley gradually approach the upper end surface of the frame 51. When the height of the conveying trolley reaches the upper end surface of the frame 51 and continues to rise, the conveying trolley can lift the raw material box 1 on the frame 51 upward to make it higher than the frame 51. At this time, the conveying trolley can move from back to front, for example, move forward the position of a raw material box 1, so as to gradually convey the raw material box 1 to the outlet end of the output device 6, so as to facilitate the unloading of the raw material box 1 after the feeding is completed. The unloaded raw material box 1 can enter the next step of the process to be filled with raw materials again.

[0101] According to some embodiments of the present invention, the automatic feeding system 100 may further include: a transfer device 3, which is arranged between the output device 6 and the removal device 2121, and the transfer device 3 can transport the raw material box 1 removed by the removal device 2121 to the input end of the output device 6.

[0102] Furthermore, the transfer device 3 may be a conveying roller 21212, a manipulator or a chain conveyor. In this way, the transfer device 3 may automatically transfer the raw material box 1 removed by the removal device 2121 to the input end of the output device 6. Of course, the type of the transfer device 3 may be reasonably selected according to actual conditions.

[0103] Combine the following Figures 1 to 4 A specific embodiment according to the present invention is described in detail.

[0104] Combination Figures 1 to 4 The working process of the automatic feeding system 100 in the present invention is as follows: first, the raw material box 1 filled with raw materials is placed on the frame of the input device 5, and then the height of the conveying trolley is raised by the lifting mechanism 52, so that it gradually lifts the raw material box 1 on the frame 51 upwards, and then the conveying trolley transports the fully loaded raw material boxes 1 one by one to the output end of the input device 5, and sends them to the waiting feeding position 211 of the placing platform 21 on the rotating lifting device 2. At this time, the placing platform 21 is in the first position, and then the lifting mechanism 22 lifts the placing platform 21 and the raw material box 1 thereon to the second position. In the process of the placing platform 21 moving from the first position to the second position, the placing platform 21 rotates under the drive of the rotating mechanism 23 on the lifting mechanism 22, so that when the placing platform 21 reaches the second position, the feeding device 4 can be opposite to the placing platform 21, and at the same time, the slot 11 side of the raw material box 1 is just rotated to be opposite to the feeding device 4.

[0105] When feeding, the feeding assembly 43 is first lifted and connected to the fully loaded raw material box 1 on the feeding position 211, and then the hydraulic cylinder mechanism is extended to make the swing frame 4341 swing upward in a vertical plane perpendicular to the ground. The upward swing of the swing frame 4341 will be converted into an upward translational movement of the feeding rod flipping mechanism 432, so that the feeding rod 4321 can drive the raw material box 1 to move upward and leave the feeding position 211 and prepare to enter the smelting furnace 7.

[0106] The second movable platform 45 moves to the right along the slide rail 421, and the rotating platform 44 and the lifting and feeding assembly 43 on the rotating platform 44 also move to the right along with the second movable platform 45 until the raw material box 1 is aligned with the furnace mouth of the smelting furnace 7, and then the first movable platform 42 moves backward along the track 41, and the second movable platform 45 moves backward along the first movable platform 42, so that the lifting and feeding assembly 43 can extend the raw material box 1 into the smelting furnace 7.

[0107] Then the feeding rod flipping mechanism 432 drives the feeding rod 4321 to rotate around the horizontal axis, so that the raw material box 1 flips to the opening facing downward, so that all the raw materials in the raw material box 1 are put into the smelting furnace 7, thereby completing the feeding. During the flipping process of the raw material box 1, the rotating platform 44 can rotate slightly to achieve the movement of the raw material box 1 in the horizontal direction, thereby achieving uniform distribution. After the feeding is completed, when the raw material box 1 flips back to the opening facing upward, the rotating platform 44 can rotate again to restore the original position. At the same time, the first moving platform 42 can move forward along the track 41, and the second moving platform 45 also moves forward with the first moving platform 42, so that the lifting and feeding assembly 43 takes the raw material box 1 that has completed the feeding out of the smelting furnace 7, and then the second moving platform 45 can move to the left along the slide rail 421 to just above the feeding position 212.

[0108] Then the hydraulic cylinder mechanism contracts, so that the swing frame 4341 swings downward in a vertical plane perpendicular to the ground. The downward swing of the swing frame 4341 will be converted into the downward translation of the feeding rod flipping mechanism 432, so that the feeding rod 4321 can drive the raw material box 1 to move downward, and put the raw material box 1 that has completed feeding into the feeding position 212. Then the lifting mechanism 22 drives the placement platform 21 to move from the second position to the first position. During this process, the rotating mechanism 23 drives the placement platform 21 to rotate 90° in the horizontal plane, so that the removal device 2121 on the placement platform 21 and the transfer device 3 are side by side and opposite to each other, and the receiving frame 2111 and the output end of the input device 5 are side by side and opposite to each other. At this time, the removal device 2121 and the transfer device 3 can transport the raw material box 1 to the output device 6, and the input device 5 can transport the raw material box 1 loaded with raw materials to the receiving frame 2111. In this way, the automatic feeding system 100 completes a complete process of loading, feeding and returning the raw material box 1.

[0109] Furthermore, the automatic feeding system 100 can automatically repeat the above process. Among them, in two adjacent feeding processes, in the process where the feeding rod 4321 is connected to the raw material box 1 and the swing mechanism 434 and the feeding rod flipping mechanism 432 work together to send the raw material box 1 into the smelting furnace 7 for feeding, the raw material box 1 that has completed the feeding in the previous time will move from the second position to the first position with the placement platform 21 along with the lifting mechanism 22 to prepare for the next loading, feeding and other work. Therefore, the automatic feeding system 100 can automatically complete the feeding work uninterruptedly and orderly.

[0110] In summary, the automatic feeding system 100 for the smelting furnace 7 disclosed in this embodiment has a high level of automation, can feed continuously, and can achieve uniform distribution, which speeds up the melting speed of raw materials, reduces the feeding time, shortens the operation cycle of the smelting furnace 7, reduces manpower consumption and eliminates safety hazards.
