[0030] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0031] Please refer to Figure 1 and Figure 2, an embodiment of the present disclosure provides a blanking device 10, including: a blanking container 11, the blanking container 11 is formed with a first inlet 111 and a first outlet 112, and the first outlet 112 is formed at the bottom of the blanking container 11; an elastic member 12, the elastic member 12 is located inside the blanking container 11 and connected to the blanking container 11; and a plug 13, the plug 13 is connected to the elastic member 12 and tends to be held at a position blocking the first outlet 112 under the elastic force of the elastic member 12, and the plug 13 can be driven to move upward to compress the elastic member 12 and open the first outlet 112.

[0032] In this embodiment, when the plug 13 is not stressed, the elastic member 12 is in an initial state and provides pressure for the plug 13 through its own elastic force, so that the plug 13 blocks the first outlet 112, and the material in the blanking container 11 cannot be discharged from the first outlet 112. When the plug 13 receives an upward acting force, the elastic member 12 compresses to provide a moving space for the plug 13. The plug 13 opens the first outlet 112, and the material in the blanking container 11 is discharged from the first outlet 112. During the entire blanking process, it is not necessary for the operator to apply force to turn over the blanking container 11 to discharge the material by pouring. Only by moving the plug 13 upward can the material be discharged, which is labor-saving and convenient to operate.

[0033] Specifically, the top of the blanking container 11 is open to form the first inlet 111.

[0034] Please refer to Figure 1 and Figure 2 , in some embodiments, a limiting protrusion 115 is formed at the bottom of the blanking container 11. The limiting protrusion 115 extends from the inner wall of the first outlet 112 towards the center of the first outlet 112. The plug 13 is located inside the blanking container 11, and the plug 13 overlaps with the limiting protrusion 115 when blocking the first outlet 112.

[0035] In this embodiment, when the elastic member 12 is in the initial state, the elastic member 12 provides a downward pressure for the plug 13. The plug 13 is stressed and abuts against the limiting protrusion 115. That is, the limiting protrusion 115 provides support for the plug 13 and prevents the plug 13 from passing through the first outlet 112 and causing the material in the blanking container 11 to leak. The cooperation between the elastic member 12 and the limiting protrusion 115 enables the plug 13 to remain at the position blocking the first outlet 112.

[0036] Specifically, the first discharge port 112 is circular, the limiting protrusion 115 is annular, and the circumferential edge of the bottom surface of the plug 13 can be entirely lapped on the limiting protrusion 115 to ensure the reliability of the plugging. The blanking container 11 includes a first section 113 and a second section 114 that are interconnected. The first section 113 has a cylindrical structure, and the second section 114 has an inverted conical structure. The first discharge port 112 is opened at the bottom of the second section 114. When the first discharge port 112 is open, the material can slide downward along the inner wall of the second section 114, that is, the inverted conical structure of the second section 114 can promote the discharge of the material from the first discharge port 112. The side wall surface of the plug 13 is arranged as an inclined surface so as to be able to fit against the inner wall of the second section 114.

[0037] Please refer to Figure 1 and Figure 2 , in some embodiments, the blanking device 10 further includes a first support 14 disposed inside the blanking container 11. The first support 14 is arranged in a hollowed-out form that allows the material to pass through, and the elastic member 12 is connected to the blanking container 11 through the first support 14.

[0038] In this embodiment, the upper end of the elastic member 12 is connected to the first support 14 and the lower end is connected to the plug 13. When an upward force acts on the plug 13, the elastic member 12 is compressed in the direction towards the first support 14 under the force, that is, the first support 14 provides support for the elastic member 12 and prevents the force acting on the plug 13 from being unable to compress the elastic member 12, thereby preventing the elastic member 12 from being unable to provide an upward moving space for the plug 13.

[0039] Specifically, the first support 14 can be integrally formed with the blanking container 11 to increase the structural strength of the first support 14. The elastic member 12 can be a spring. The blanking device 10 further includes a guiding cylinder 17 with both ends open. The guiding cylinder 17 is fixed on the first support 14, and the elastic member 12 is located inside the guiding cylinder 17, so that the elastic member 12 can elastically deform along the extending direction of the guiding cylinder 17, that is, the direction of the elastic deformation of the elastic member 12 is restricted.

[0040] Please refer to Figure 1 and Figure 2 , in some embodiments, the blanking device 10 further includes a connecting rod 16 and a disturbing member 15 connected to the plug 13. The plug 13 is connected to the elastic member 12 through the connecting rod 16. The disturbing member 15 is arranged to be able to move relative to the blanking container 11 synchronously with the plug 13. The disturbing member 15 includes one or more disturbing rods 151 connected to the connecting rod 16. An angle is formed between the disturbing rod 151 and the connecting rod 16, and the plurality of disturbing rods 151 are arranged at intervals in sequence along the circumference of the connecting rod 16.

[0041] In this embodiment, the connecting rod 16 is used to connect the elastic member 12 and the plug 13. At the same time, the connecting member provides an installation position for the disturbing rod 151. The disturbing rod 151 is located inside the blanking container 11 and can be buried inside the material filled in the blanking container 11. When the plug 13 moves upward under force, the disturbing rod 151 moves upward synchronously with the plug 13 to disturb the material, and can separate the adhered material, avoiding the formation of over-sized lumpy materials due to material adhesion and blocking the first discharge port 112.

[0042] Specifically, the connecting rod 16 has a cylindrical structure, and the disturbing rod 151 is perpendicular to the connecting rod 16.

[0043] Please refer to Figures 1 to 6 , this embodiment of the present disclosure further provides a feeding system, including a driver 20 and the above-mentioned blanking device 10. The driver 20 is used to drive the plug 13 to move upward.

[0044] In this embodiment, the blanking device 10 of the feeding system has all the technical solutions and all the technical effects of the above-mentioned blanking device 10, which will not be elaborated here.

[0045] Please refer to Figures 1 to 6 , in some embodiments, the feeding system further includes a silo 30 and a second support 120. A second feeding port 31 and a second discharge port 32 are formed on the silo 30. The second feeding port 31 is formed at the top of the silo 30. The driver 20 is arranged above the silo 30 through the second support 120 so as to be able to drive the plug 13 in the blanking device 10 located above the silo 30 to move upward.

[0046] In this embodiment, the blanking device 10 moves above the silo 30. The driver 20 drives the plug 13 to move upward, so that the material in the blanking container 11 is discharged from the first discharge port 112 and enters the silo 30 through the second feeding port 31. The second support 120 is used to fix the driver 20 above the silo 30, so that after the driver 20 drives the plug 13 to open the first discharge port 112, the material in the blanking container 11 can fall into the silo 30 under the action of its own gravity.

[0047] Specifically, the feeding system further includes a feeding platform 90, which is higher than the ground. An installation hole is provided on the feeding platform 90. The silo 30 passes through the installation hole, and the upper side wall of the silo 30 is connected to the inner wall of the installation hole, and the lower part of the silo 30 is located below the installation hole. The second bracket 120 is fixed on the feeding platform 90, and the second bracket 120 can be in a hollowed-out form that allows materials to pass through, or it can be a portal frame. The driver 20 is located directly above the center of the silo 30. The driver 20 can be a threaded rod. A threaded hole is provided on the second bracket 120, and the threaded rod is threadedly connected to the threaded hole. By screwing the threaded rod, it moves upward, and drives the plug 13 of the feeding device 10 above the silo 30 to move upward in a jacking manner to achieve discharging. The way of screwing the threaded rod can be achieved manually or by a motor; the driver 20 can also be a hydraulic cylinder, and the lifting is achieved through hydraulic pressure to drive the plug 13 to move upward.

[0048] Both the top and bottom of the silo 30 are open, and respectively form a second inlet 31 and a second outlet 32. The feeding system further includes a weight sensor 60 and a magnetic grating 70 provided on the silo 30, and a dust collector 110 and a screw feeder 80 connected to the silo 30. The weight sensor 60 is used to monitor the mass of the materials in the silo 30 in real time to determine whether all the materials in the feeding container 11 have been discharged into the silo 30. Since the second bracket 120 is connected to the feeding platform 90, the weight of the feeding device 10 borne by the driver 20 when driving the plug 13 to move upward will not be detected by the weight sensor 60, ensuring that only the weight of the materials in the silo 30 is detected by the weight sensor 60; the dust collector 110 is connected to the upper part of the silo 30 through a pipeline to dust the materials entering the silo 30 and reduce the dust hazard; the screw feeder 80 is connected to the second outlet 32, and the materials in the silo 30 are transported through the screw feeder 80.

[0049] Please refer to Figures 1 to 6 , in some embodiments, the feeding system further includes a conveying device 40. The silo 30 is arranged below the conveying path of the conveying device 40, and the conveying device 40 is used to convey the feeding device 10 above the silo 30.

[0050] In this embodiment, the feeding device 10 is conveyed above the silo 30 through the conveying device 40, replacing the way of lifting by a lifting device in the prior art, avoiding the shaking of the feeding device 10 during lifting due to its large weight and being suspended in the air, and further avoiding safety accidents caused by the falling of the feeding device 10. In addition, the feeding device 10 feeds directly above the silo 30, generating less dust compared to the way of pouring and feeding in the prior art.

[0051] Please refer to Figures 1 to 6, in some embodiments, the conveying device 40 includes a conveying chain 41 and a conveying rack 42 fixed on the conveying chain 41. The conveying chain 41 is formed in a through form allowing materials to pass through in the vertical direction. An installation hole 421 is formed on the conveying rack 42. The blanking container 11 is erected on the conveying rack 42, and the first discharge port 112 is arranged below the conveying rack 42 through the installation hole 421.

[0052] In this embodiment, the conveying chain 41 moves, driving the conveying rack 42 to move, and further driving the blanking container 11 erected on the conveying rack 42 to move directly above the storage bin 30, realizing the conveying of materials.

[0053] Specifically, the conveying chain 41 can extend to two workstations to convey the blanking device 10 from one workstation to another. Two conveying chains 41 are provided. When the blanking container 11 is erected on the conveying rack 42, the two conveying chains 41 are respectively located on opposite sides of the blanking container 11. The conveying chain 41 can be driven by a motor, and the motor can be controlled remotely or by connecting to a host computer.

[0054] The feeding system further includes a loading platform 100. A lifting elevator is arranged on one side of the loading platform 100. The completed blanking device 10 is transported to the loading platform 100 through the lifting elevator. One end of the conveying device 40 is located at the loading platform 100 and the other end is located at the feeding platform 90 to convey the blanking device 10 between the loading platform 100 and the feeding platform 90: The conveying device 40 conveys the blanking device 10 filled with materials from the loading platform 100 to the feeding platform 90 and is directly above the storage bin 30. After the blanking device 10 discharges all the materials into the storage bin 30, the conveying device 40 then conveys the empty blanking device 10 from the feeding platform 90 to the loading platform 100 for reloading, and so on until the materials in the storage bin 30 reach the required amount. The height of the loading platform 100 is the same as that of the feeding platform 90, so that the conveying device 40 only realizes horizontal conveying, avoiding the plug 13 being unable to move due to inclined conveying and resulting in discharge failure.

[0055] Please refer to Figures 1 to 6 , in some embodiments, the conveying device 40 includes a plurality of conveying racks 42 arranged at intervals on the conveying chain 41 in sequence. The conveying chain 41 is arranged in a ring to form a circular conveying path. A plurality of storage bins 30 are provided, and the number of storage bins 30 is less than the number of conveying racks 42.

[0056] In this embodiment, one blanking device 10 can be erected on each conveying rack 42. When a blanking device 10 moves directly above a storage bin 30 and discharges materials, it moves along the circular conveying chain 41. At the same time, the next blanking device 10 moves directly above this storage bin 30 to discharge materials again. The interval time between each discharge is short, which can improve the discharging efficiency.

[0057] Specifically, two silos 30 are provided, and four conveying frames 42 are provided. Every two of them form a group. The two conveying frames 42 in each group respectively correspond to two silos 30, and the distance between the two conveying frames 42 on the conveying chain 41 is the same as the distance between the two silos 30 along the extending direction of the conveying chain 41. In a group of conveying frames 42, when one conveying frame 42 moves to directly above one silo 30, the other conveying frame 42 also moves to directly above the other silo 30. The blanking devices 10 mounted on the two conveying frames 42 can blank simultaneously, that is, the two silos 30 can be filled simultaneously. After the blanking of the blanking devices 10 conveyed by a group of conveying frames 42 is completed, the next group of conveying frames 42 conveys the next group of blanking devices 10 to blank simultaneously again. The number of blanking devices 10 can be the same as the number of conveying frames 42 or more than the number of conveying frames 42. The number of drivers 20 is the same as the number of conveying frames 42. Infrared sensors 130 are provided on the blanking devices 10 or at the fixed parts of the conveying device 40. Two infrared sensors 130 are provided, corresponding to the two silos 30 respectively, and are used to detect whether the conveying frame 42 moves to directly above the silo 30. The infrared sensors 130 can be used in conjunction with a host computer. When the infrared sensors 130 detect that the conveying frame 42 moves to directly above the silo 30, the detection signal is transmitted to the host computer, and the host computer controls the conveying chain 41 to stop. When multiple conveying frames 42 are provided, through the program control of the host computer, when the infrared sensor 130 corresponding to each silo 30 detects that the first conveying frame 42 reaches directly above the silo 30, the conveying chain 41 does not stop, and the conveying chain 41 stops until the second conveying frame 42 reaches directly above the silo 30, so that after a silo 30 filled with materials stays above each of the two silos 30, the conveying chain 41 is then controlled to stop.

[0058] Please refer to Figures 1 to 6 , in some embodiments, the feeding system further includes an emergency device 50, and the emergency device 50 is used to lift and move the blanking device 10 to above the silo 30.

[0059] In this embodiment, when the conveying device 40 fails, blanking can be carried out by lifting the blanking device 10 through the emergency device 50, so as to avoid fluctuations in the material conveying caused by the shutdown and maintenance of the conveying device 40, and further avoid affecting the material conveying efficiency, so as to ensure the normal conveying of materials.

[0060] Specifically, the emergency device 50 includes a suspension rail 51, a suspension tool 52, and a hoist 53. The suspension rail 51 is located above the silo 30, and the extending direction of the suspension rail 51 is from the feeding platform 90 to the loading platform 100. The suspension tool 52 is used to connect the blanking container 11 and vertically lift and move along the suspension rail 51 under the drive of the hoist 53. The blanking device 10 includes two hooks 18 provided on the side wall of the first section 113 of the blanking container 11. The two hooks 18 are oppositely arranged, and the hooks 18 are used to connect with the suspension tool 52. The suspension tool 52 can be a chain.
