Description

Technical Field

[0001] The invention relates to the technical field of graphite packaging equipment, and in particular to a packaging device for graphite production. Background Art

[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and is not easy to react with acids, alkalis and other agents. With its excellent physical and chemical properties, graphite can not only be used as an anti-wear agent and lubricant, but also high-purity graphite can be used as a neutron moderator in atomic reactors. At the same time, graphite can also be used to make crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, pencil refills, etc. It can be seen that graphite is used in many fields.

[0003] In many fields, graphite is often used in the form of powder. In the graphitization production process of lithium battery negative electrode materials, the negative electrode powder raw material is graphitized to make lithium battery negative electrode materials (i.e. graphite). After cooling, the negative electrode materials need to go through the process of screening, demagnetization and packaging.

[0004] In the existing packaging process, workers are often required to open the opening of the bag and align the opening with the storage barrel to receive the graphite from the storage barrel. When the graphite in the bag is filled to a certain position, the storage barrel is closed and the bag containing graphite is transported to the next worker for weighing. The worker increases or decreases the graphite in the bag according to the weighing data to ensure that the weight of the graphite in the bag is within a predetermined error range. After the weighing is completed, the bag is vacuum-packed and then transported to the storage room for storage.

[0005] The existing packaging process has the following problems: 1. When the staff are holding the bag and weighing the graphite, they are prone to inhaling graphite powder, which affects their health;

[0006] 2. The efficiency of weighing and packaging is very slow, and the weight error of each bag of graphite is relatively large;

When the bag moves to the bottom of the weighing component, the extension tube extends into the bag, and the first clamping component and the second clamping component wrap the bag on the extension tube. After unloading, The extension tube is retracted, and the annular guide conveyor line and the conveyor continue to convey. When the material bag is conveyed to the bottom of the suction component, the position of the heat-sealing part is adjusted by the first movable component and the second movable component, and in cooperation with the suction component, the unloaded material bag is vacuumed and heat-sealed. Then the conveyor conveys the packaged material bag to the vicinity of the storage room for centralized collection, and the staff centrally transports the material bag to the storage room for storage. The present invention realizes full automatic control through the mutual cooperation of the conveyor, the annular guide conveyor line, the material bag distributing equipment, the unloading equipment, the vacuum packaging equipment and the first clamping component, which replaces the manual handling and bagging operations, saves time, reduces costs and improves work efficiency.

[0085] Working principle: When in use, when the first clamping assembly 6 is aligned with the material bag dispensing device 3, the height of the first clamping plate 70 is finally adjusted by the first telescopic member 61, and the telescopic end of the third telescopic member 65 is extended. With the cooperation of the guide slot 691 and the guide block 661, the first clamping plates 70 are made to approach each other while rotating from a horizontal state to a vertical state. During the rotation of the first clamping plates 70, the second telescopic member 63 can cooperate to extend. When the two first clamping plates 70 are rotated to a vertical state, they can clamp both sides of the material bag, and then the second telescopic member 63 retracts to take the material bag out of the outlet. The third telescopic member 65 retracts, so that the first clamping plate 70 returns from a vertical state to a horizontal state, and the material bag mouth is opened by the adhesive strip 71, so that the material bag rotates. , the material bag opening is facing upward, and then the material bag is conveyed to the conveyor 1 through the conveyor of the circular guide rail conveyor line 2. The first clamping plate 70 and the material bag move synchronously with the conveyor 1. When the material bag is conveyed to the bottom of the weighing barrel 451, the conveyor 1 stops moving, and the second cross bar 49 is driven to move downward by the telescopic end of the fourth telescopic member 48, thereby driving the extension tube 46 to move downward, so that the extension tube 46 extends into the material bag. At the same time, the extension tube 46 drives the second connecting rod 472 to move downward and rotate, and the second connecting rod 472 drives the first connecting rod 471 to move downward and rotate, so that the two second clamping plates 473 can move closer to each other. At the same time, the two sides of the material bag opening are closed. Finally, the two sides of the material bag opening are closed on the extension tube 46, and the third telescopic member can be used to close the two sides of the material bag opening. 65 is extended, the first clamping plate 70 is clamped on both sides of the extension tube 46 adjacent to the second clamping plate 473 (at this time, the guide block 661 is located in the front section of the guide slide groove 691, and the first clamping plate 70 does not rotate), the discharge pipe 455 is opened to discharge the material, and the discharge is completed with the cooperation of the vibration motor 457. After the discharge is completed, the discharge pipe 455 is closed, the third telescopic member 65 and the fourth telescopic member 48 are retracted, and the extension tube 46 moves upward to leave the material bag, and then the circular guide rail conveyor line 2 and the conveyor 1 continue to move synchronously. When the material bag is conveyed to the bottom of the L-shaped bracket 59, the conveyor 1 stops moving, and the second motor 532 drives the threaded rod 531 to rotate, thereby driving the first threaded plate 533 to move, and finally drives the two second threaded plates 5 53 moves to a state where the material bag opening can be completely clamped, the telescopic end of the fifth telescopic member 54 is lowered, so that the suction pipe 572 enters the material bag, and the second threaded plate 553 is located below the first clamping plate 70, and then the bidirectional screw rod 551 is driven to rotate by the third motor 552, thereby driving the two second threaded plates 553 to approach each other, and the material bag opening is closed again, so that the first clamping plate 70 is separated from the material bag, and the material bag opening is sealed by the fitting of the two sealing plates 554, and the abutting plate 555 is fitted with the heat sealing member 56, and the material bag is evacuated by the cooperation of the vacuum pump 571 and the suction pipe 572. After evacuation, the heat sealing member 56 is energized to heat it, and the open end of the material bag is welded and sealed, and then the second threaded plates 553 are separated.The fifth telescopic member 54 is retracted, and the circular guide rail conveyor line 2 and the conveyor 1 are started. The circular guide rail conveyor line 2 finally realigns the first clamping plate 70 with the material bag dispensing device 3, and the conveyor 1 continues to convey the packaged material bags forward, and finally conveys them to the vicinity of the storage room for centralized collection. The staff can centrally carry the material bags to the storage room for storage, realizing full automatic control, replacing manual handling and bagging operations, saving time, reducing costs, and improving work efficiency;

[0086] When the graphite in the weighing barrel 451 is discharged into the material bag, the discharge pipe 455 is closed, and the conveying pipe 433 is opened. The graphite in the storage barrel 431 falls into the weighing barrel 451 through the conveying pipe 433. When the electronic scale 454 detects that the weighing barrel 451 has reached the specified weight, the conveying pipe 433 is closed, and the next material bag is waited for to be transported to the bottom of the weighing barrel 451 for discharge. This process is repeated to complete the quantitative packaging of graphite, effectively improving the packaging efficiency.
