Description

Technical Field

[0001] The utility model relates to the field of material transfer equipment, in particular to a bagging, metering and bagging system for block materials. Background Art

[0002] In the bulk material processing industry, in order to avoid contamination during transportation, plastic bags are often used for packaging and transportation. The weight of each bag of material is required to be bagged according to the set weight and weighing error. In order to facilitate subsequent circulation, the external dimensions of the packaging materials need to be limited. Therefore, the fully automatic and accurate measurement of bulk materials is a technical challenge. There are currently two technologies on the market: the first is that materials with about 95% of the target weight use the solution of automatic feeding and automatic measurement by upstream equipment, and the remaining 5% of the materials use the solution of manual feeding and manual measurement; the second is that materials with about 95% of the target weight use the solution of automatic feeding and automatic measurement by upstream equipment, and the remaining 5% of the materials use the solution of manual feeding and two-level or multi-level automatic measurement.

[0003] In the prior art, CN210437431U discloses a fast weighing device for bulk polysilicon, and CN112389754B discloses a rotary automatic packaging device for bulk polysilicon. The bulk polysilicon material first falls from the feeder into the weighing hopper, then falls from the weighing hopper into the transition hopper above the receiving barrel, then falls from the filter hopper into the receiving barrel, and finally slides from the side wall of the receiving barrel to the bottom of the barrel. During the metering and loading process, the material falls four times. In particular, the drop in the process is large, and the generated broken materials and dust impurities cannot be discharged, resulting in a decrease in product quality. In addition, in the system combined with CN210437431U and CN112389754B, due to the addition of the weighing hopper and the transition hopper, the area in contact with the material increases, and the equipment procurement cost is high for customers, and more maintenance costs will be incurred later. Meanwhile, CN215475878U discloses a bulk polysilicon gross weight rotary packaging device and CN219545122U discloses a bulk polysilicon automatic fine batching device. In the gross weight rotary packaging device, the weighing sensor is fixed on the turntable to participate in the rotary motion, which requires a long stabilization time. Under the condition of meeting the specified production capacity, the weighing error is relatively large, about 500g-800g; therefore, in order to achieve precise weighting, the weighing weight of the bulk polysilicon automatic fine batching device is required to be large (about 500g-800g). Since the bulk polysilicon automatic fine batching device is offline feeding relative to the upstream automatic feeding equipment and is far away from the upstream automatic feeding equipment, it needs to be offline transported and fed about 150Kg per hour, resulting in excessive labor intensity of the production line, and the debris and dust impurities generated during the secondary feeding of a large amount of materials cannot be discharged, resulting in a decline in product quality.

[0004] Therefore, there is a problem in the prior art that bulk materials cannot be truly fully automatically and accurately measured. Utility Model Content

[0031] When using the bulk material belting, metering and bagging system in the present application, since there is a rotary metering bagging machine 20, when bagging the material, the empty material bag can be put on the rotary metering bagging machine 20 through the bagging component 30, and the material bag will pass through multiple feeding components 50 in sequence during the rotation of the rotary metering bagging machine 20, so that multiple feeding can be achieved through multiple feeding components 50.

[0033] Specifically, the feeding assembly 50 includes a feeding bin 51, at least one feeding feeder 52, and a feeding dust removal unit 53. One end of the feeding feeder 52 is connected to the feeding bin 51; the feeding dust removal unit 53 is arranged at one end of the feeding feeder 52 away from the feeding bin 51. In the present application, by providing the feeding dust removal unit 53, dust can be removed during the process of the feeding feeder 52 feeding the material bag.

[0034] Specifically, there are three feeding assemblies 50, two of which are arranged at intervals in the rotation direction of the rotary metering bagging machine 20, one feeding assembly 50 is arranged on one side in the length direction of the conveying line assembly 10, and the feeding assembly 50 arranged on one side in the length direction of the conveying line assembly 10 is close to the discharge end 12 relative to the rotary metering bagging machine 20. Preferably, the bagging assembly 30 corresponding to the rotary metering bagging machine 20, the two feeding assemblies 50 and the bag unloading assembly 40 are arranged at intervals of 90 degrees around the circumference of the rotary metering bagging machine 20.

[0035] Optionally, two feeding assemblies 50 spaced apart in the rotation direction of the rotary metering bagging machine 20 each have a feeding feeder 52 .

In a specific embodiment of the present application, on the conveying path of the material bag, the measurement accuracy of the weighing assembly 60 through which the material bag passes gradually increases, and the size of the material in the feeding bin 51 of the corresponding feeding assembly 50 through which the material bag passes gradually decreases, thereby effectively improving the accuracy of feeding.

[0038] In a specific embodiment of the present application, the weighing assembly 60 corresponding to the feeding assembly 50 arranged on one side of the length direction of the conveying line assembly 10 is arranged below the conveying line assembly 10. Of course, in the present application, the setting position of the weighing assembly 60 can also be adjusted according to the actual use situation, as long as it does not affect the normal operation of the conveying line assembly 10 and ensures that the material can be weighed.

[0039] Specifically, the rotary metering bagging machine 20 includes a frame 21, a turntable 22, a driving member 23, and a receiving barrel 24. The turntable 22 is rotatably arranged on the frame 21; the driving member 23 is arranged on the frame 21 and is drivingly connected to the turntable 22 to drive the turntable 22 to rotate relative to the frame 21; the receiving barrel 24 is movably arranged on the turntable 22 and rotates with the turntable 22, and the bagging assembly 30 can sleeve the material bag on the receiving barrel 24. In a specific embodiment of the present application, the weighing assembly 60 can be raised and lowered. When the turntable 22 drives the receiving barrel 24 to rotate to the corresponding feeding assembly 50 and the weighing assembly 60, the weighing assembly 60 rises upward and lifts the receiving barrel 24. At this time, the receiving barrel 24 is separated from the turntable 22, and the weighing assembly 60 can be connected to the barrel 24 for weighing. After the weighing is completed, the weighing assembly 60 descends. At this time, the receiving barrel 24 can be reconnected with the turntable 22 under the action of gravity and move with the turntable 22. Preferably, the rotary metering bagging machine 20 further includes a barrel clamping device 25 , and the barrel clamping device 25 can lock the receiving barrel 24 and the turntable 22 .

[0040] Specifically, the bag unloading assembly 40 includes a conveying portion 41, a lifting bracket 42, a lifting driving portion 43, and a lifting guide portion 44.

[0042] Optionally, the bulk material conveying, metering and bagging system further includes an empty material basket weighing assembly 80, which is arranged at one end of the bag unloading assembly 40 away from the conveyor line assembly 10, and a weighing assembly 60 is correspondingly arranged at the bottom of the empty material basket weighing assembly 80. At the same time, the empty material basket weighing assembly 80 has multiple material baskets 90, and the material baskets 90 circulate back and forth on the conveyor line assembly 10. Three weighing assemblies 60 are arranged on the conveyor line assembly 10 to weigh the material baskets 90, and among the three weighing assemblies 60, the first weighing assembly 60 is located upstream of the bag unloading assembly 40 and corresponds to the empty material basket weighing assembly, the second weighing assembly corresponds to the feeding assembly 50 arranged on one side of the length direction of the conveyor line assembly 10, and the third weighing assembly 60 is arranged downstream of the second weighing assembly 60. It should be noted that in the present application, when the first weighing assembly weighs the material basket, only the material basket itself is weighed at this time. After the basket moves to the bag unloading assembly 40, the bag containing the material will enter the basket, so the second and third weighing assemblies behind weigh the basket containing the bag and the material. At the same time, the third basket is the weighing assembly for the weight recheck mentioned above. In addition, the bag unloading assembly 40 may also include a centering portion 45, which is arranged above the conveying portion 41, and when the empty basket of the empty basket weighing assembly 80 enters the bag unloading assembly 40, it can be centered by the centering portion 45.

[0044] In a specific embodiment of the present application, the use of the bulk material belting, metering and bagging system in the present application mainly includes the following steps:

[0045] 1) When there is a formula requirement and the equipment is in normal condition, the first material basket 90 on the empty material basket weighing component 80 is weighed by the weighing component 60 corresponding to the empty material basket weighing component 80, and the empty material basket weighing process is executed: the weighing frame 63 of the weighing component 60 is raised, and if it is within the error range, the material basket 90 will reach the automatic bag unloading position driven by the conveying part 41 of the bag unloading component 40, and the centering part 45 of the bag unloading component 40 will accurately position the material basket 90, otherwise it will stop and alarm to wait for manual cleaning; at the same time, the 1# empty material bag passes through the bag loading component 30 and is automatically put on the material receiving barrel 24 at the bag loading station where the bag loading component 30 is located;

[0046] 2) The driving part 23 of the rotary metering bagging machine 20 drives the turntable 22 to rotate a fixed angle, and the 2# empty bag enters the bagging station to repeat process 1; the 1# empty bag enters the 1st metering station to execute the large-size material metering process: the weighing frame 63 of the weighing component 60 raises the receiving barrel 24 of the docking station, and at the same time, the receiving barrel 24 is completely separated from the turntable 22, and the tare weight is recorded and then removed. The feeding feeder 52 of the upper feeding component 50 starts feeding, and stops metering after reaching the set weighing range and error. The weighing frame 63 of the weighing component 60 drives the receiving barrel 24 to descend, realizing the complete separation of the weighing frame 63 of the weighing component 60 and the receiving barrel 24. At the same time, the receiving barrel 24 and the turntable 22 are automatically docked by gravity, and the barrel clamping device locks the receiving barrel 24 and the turntable 22. During the feeding process, the dust removal part participates in the collection of the unloading dust;

[0047] 3) After the current action process of each station is completed, the driving part 23 of the rotary metering bagging machine 20 drives the turntable 22 to rotate a fixed angle, and the 3# empty bag enters the bagging station to repeat process 1, the 2# empty bag enters the first metering station to repeat process 2, and the 1# bag enters the second metering station to perform the medium-sized material metering process: the corresponding weighing frame 63 of the weighing component 60 here raises the receiving barrel 24 of the docking station, and at the same time, the receiving barrel 24 is completely separated from the turntable 22, and the tare weight is recorded and then removed. The feeding feeder 52 of the feeding component 50 above the station here starts to feed, and stops metering after reaching the set weighing range and error. The weighing frame 63 of the weighing assembly 60 drives the receiving barrel 24 to descend, realizing the complete separation of the weighing frame 63 of the weighing assembly 60 and the receiving barrel 24. At the same time, the receiving barrel 24 and the turntable 22 are automatically docked by gravity, and the barrel clamping device locks the receiving barrel 24 and the turntable 22. During the feeding process, the dust removal part participates in the collection of the unloading dust.

[0048] 4) After the action processes of each current station are completed, the driving part 23 of the rotary metering bagging machine 20 drives the turntable 22 to rotate a fixed angle, and the 4# empty bag enters the bag loading station to repeat process 1, the 3# empty bag enters the 1st metering station, and the 2# bag enters the 2nd metering station; the 1# bag enters the unloading station where the bag unloading assembly 40 is located, and the unloading process is executed: the lifting drive part 43 below rises so that the bottom of the material basket docks with the bottom of the material receiving barrel 24 of this station. After the material receiving barrel 24 is released, the lifting drive part 43 descends, and the 1# bag detaches from the material receiving barrel 24 and enters the material basket 90.

[0049] 5) After the action processes of each current station are completed, the driving part 23 of the rotary metering bagging machine 20 drives the turntable 22 to rotate a fixed angle, and the 5# empty bag enters the bagging station to repeat process 1; the 4# empty bag enters the 1st metering station to execute the large-size material metering process; the 3# bag enters the 2nd metering station to execute the medium-size material metering process; the 2# bag enters the bag unloading station to execute the bag unloading process, and this cycle repeats.

[0050] 6) Driven by the conveyor line assembly 10, the 1# material bag leaves the bag unloading station along with the material basket and arrives directly above the weighing assembly 60 corresponding to the feeding assembly 50 corresponding to the conveyor line assembly 10. This is the third metering station, and the small-size material metering process is executed: the weighing frame 63 of the weighing assembly 60 here is raised, and the two feeding feeders 52 of the feeding assembly 50 above start to feed, and the metering stops after reaching the set weighing range and error.

[0051] 7) The 1# bag continues to move with the basket to the top of the weighing device for weight rechecking under the drive of the conveyor assembly 10, and the weight rechecking process is executed: the weighing frame 63 of the weighing assembly 60 here rises, and if it is within the error range, it will automatically pass, otherwise it will stop and alarm and wait for manual processing, and the corresponding set weight and current weight and other information will be displayed on the touch screen 70. At the same time, the 2# bag moves with the basket to the top of the weighing assembly 60 corresponding to the feeding assembly 50 corresponding to the conveyor assembly 10, and the small-size material metering process is executed; the 2# bag enters the bag unloading station and executes the bag unloading process; the 4# bag enters the second metering station to execute the medium-size material metering process, and the 5# empty bag enters the first metering station to execute the large-size material metering process.

[0052] The first metering station mentioned above is the station corresponding to the first feeding assembly 50 and the weighing assembly 60 that the receiving barrel 24 passes through in the rotation direction of the rotary metering bagging machine 20. The second metering station is the station corresponding to the second feeding assembly 50 and the weighing assembly 60 that the receiving barrel 24 passes through in the rotation direction of the rotary metering bagging machine 20.
