Description

Technical Field

[0001] This application relates to the field of negative electrode graphitization technology, and more specifically, to a graphitization crucible conveying device. Background Technology

[0002] Anode graphitization is a key process in the production of anode materials for lithium-ion batteries. Through high-temperature heat treatment, usually above 2800℃, the disordered carbon structure of carbon materials (such as petroleum coke and needle coke) is transformed into a regular graphite crystal structure, thereby improving the conductivity, capacity and stability of the material.

[0003] Since the graphitization stage of the negative electrode requires high-temperature processing, the material needs to be loaded into a high-temperature resistant crucible. However, manual operation in a high-temperature furnace is dangerous and inefficient. Therefore, crucible conveying devices are usually used to automate the conveying and unloading of crucibles, which significantly improves production safety, consistency and efficiency, while reducing quality fluctuations caused by human factors.

[0004] Currently, when performing negative electrode graphitization, the material is usually first loaded into a crucible, and then the crucible is transported to the appropriate position by the rotation of the conveyor roller. However, the crucible is prone to displacement during the conveying process, and the material inside the crucible is relatively loose when it is put into the crucible. During the conveying process, the material is easy to spill or escape due to the slight vibration of the conveyor roller. To avoid this problem, the amount of material conveyed at one time is usually reduced, which affects the work efficiency. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a graphitization crucible conveying device, which has the advantages of stable conveying and easy material compaction.

[0006] To achieve the above objectives, this application provides the following technical solution: a graphitization crucible conveying device, comprising a roller conveyor and a crucible, wherein the roller conveyor is provided with multiple sets of conveying rollers inside, a fixed platform is fixedly installed on the top of the roller conveyor, a cylinder is fixedly installed on the top of the fixed platform, the telescopic end of the cylinder passes through the interior of the fixed platform and is fixedly connected to a compaction plate, and the roller conveyor is used to convey the crucible;

[0007] The roller conveyor is equipped with a drive mechanism, which includes a fixed shell fixedly installed at the bottom of the conveyor roller. Guide grooves are provided on the front and rear sides of the top of the fixed shell. A movable plate is movably installed at the bottom of each set of guide grooves. A limit mechanism is provided above the conveyor roller. The limit mechanism includes connecting columns fixedly connected to two sets of movable plates respectively. The tops of the front and rear sets of connecting columns penetrate the guide grooves and extend to the top of the conveyor roller through the gap between the conveyor rollers. The connecting columns and guide plates are fixedly connected.

[0008] As a preferred technical solution of this application, the ends of the two sets of guide plates near the compaction plate are parallel to each other, and the ends of the two sets of guide plates away from the compaction plate are arranged in a V-shape.

[0009] As a preferred technical solution of this application, a rotating disk is rotatably installed inside the fixed shell. Connecting rods are hinged to both the front and rear ends of the bottom of the rotating disk, and the connecting rods are located at the eccentric position of the rotating disk. The other end of the connecting rod is hinged to the movable plate, and the connecting rod is located at the center position of the bottom of the movable plate.

[0010] As a preferred technical solution of this application, two sets of brackets are fixedly installed inside the fixed shell, and a worm gear is rotatably installed between the two sets of brackets. A motor is fixedly installed inside the fixed shell, and the output shaft of the motor is fixedly connected to the worm gear. A worm wheel is fixedly installed at the bottom of the rotating disk, and the worm wheel is connected to the worm gear in a transmission manner.

[0011] As a preferred technical solution of this application, it also includes a support mechanism, which includes a fixed base placed on the conveying roller. The fixed base is used to support and accommodate the crucible. Multiple sets of protruding plates are fixedly installed on the outer wall of the fixed base. A rotating rod is rotatably installed between each set of protruding plates. A limit block is provided at the top of the rotating rod. The multiple sets of limit blocks are used to clamp and limit the crucible.

[0012] As a preferred technical solution of this application, the outer wall of the rotating rod is provided with a fixing hole, the fixing hole is located on one side of the rotating shaft of the rotating rod, and a pull rod is movably installed on the outer wall of the convex plate. One end of the pull rod passes through the interior of the fixing hole, and the pull rod and the convex plate are elastically connected by a spring.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] 1. This application utilizes a roller conveyor to transport crucibles. During transport, two sets of guide plates restrict the movement path of the crucibles. Furthermore, when the crucible is inside the fixed platform, the synchronous relative displacement of the two sets of guide plates fixes the crucible at the center of the fixed platform, and the pressing down of the compaction plate compacts the material inside the crucible. This device ensures stable crucible movement and avoids material spillage caused by vibration during the operation of the conveyor rollers by compacting the material, thereby reducing material loss and ensuring conveying quality.

[0015] 2. This application ensures that the crucible can be stably transported by the roller conveyor through the setting of the support mechanism, and fixes the position of multiple sets of rotating rods by the tie rod. After the rotating rods are fixed, the limiting block will fit tightly against the outer wall of the crucible, thereby clamping and limiting the crucible. This device ensures the stability of the crucible during transportation by supporting the outer wall of the crucible, further preventing the spillage of hot materials and improving safety performance.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0025] like Figures 1 to 6 As shown, the graphitization crucible conveying device provided in this application includes a roller conveyor 1 and a crucible 5. The roller conveyor 1 is provided with multiple sets of conveying rollers 15 inside. A fixed platform 11 is fixedly installed on the top of the roller conveyor 1. A cylinder 13 is fixedly installed on the top of the fixed platform 11. The telescopic end of the cylinder 13 passes through the interior of the fixed platform 11 and is fixedly connected to the compaction plate 14. The roller conveyor 1 is used to convey the crucible 5.

[0026] The roller conveyor 1 is equipped with a drive mechanism 2. The drive mechanism 2 includes a fixed shell 21 fixedly installed at the bottom of the conveyor roller 15. The fixed shell 21 has guide grooves 22 on both the front and rear sides of the top. A movable plate 23 is movably installed at the bottom of each set of guide grooves 22. A limit mechanism 3 is provided above the conveyor roller 15. The limit mechanism 3 includes connecting columns 31 fixedly connected to the two sets of movable plates 23 respectively. The tops of the front and rear sets of connecting columns 31 pass through the guide grooves 22 and extend to the top of the conveyor roller 15 through the gap between the conveyor rollers 15. The connecting columns 31 and the guide plates 32 are fixedly connected.

[0027] The operator first connects the device to the power supply and starts the roller conveyor 1 through the main control panel 12 located on the front side of the roller conveyor 1. At this time, the front-end equipment will fill the inside of the crucible 5 with material, and then the crucible 5 will be conveyed by the rotation of the conveying roller 15. At this time, the crucible 5 will immediately enter the inside of the fixed platform 11. By the limiting of the guide plate 32, the crucible 5 is placed in the center position inside the fixed platform 11. After the crucible 5 moves to the bottom of the compaction plate 14, the operator operates the roller conveyor 1 and starts the cylinder 13 through the main control panel 12 to make the compaction plate 14 downward and compact the material inside the crucible 5. After the compaction operation is completed, the operator can start the roller conveyor 1 again for conveying operation. After the above steps, the crucible 5 will be guided by the guide plate 32 to ensure the stability of the conveying, and the compaction of the compaction plate 14 will prevent the material from spilling.

[0028] The crucible 5 is conveyed by the operation of the roller conveyor 1. During the conveying process, the movement path of the crucible 5 is restricted by two sets of guide plates 32. Furthermore, when the crucible 5 is inside the fixed platform 11, the synchronous relative displacement of the two sets of guide plates 32 can fix the crucible 5 at the center position of the fixed platform 11 and, together with the downward pressure of the compaction plate 14, compact the material inside the crucible 5. This device can ensure the stable movement of the crucible 5, and by compacting the material with the compaction plate 14, it can avoid the problem of material spillage caused by the vibration of the conveying roller 15 during operation, reduce material loss, and ensure the conveying quality.

[0029] Among them, the ends of the two sets of guide plates 32 that are close to the compaction plate 14 are parallel to each other, and the ends of the two sets of guide plates 32 that are away from the compaction plate 14 are set in a V-shape.

[0030] The V-shaped design of the two sets of guide plates 32 at the ends away from the compaction plate 14 allows the crucible 5 to gradually move towards the middle position of the guide roller conveyor 1 as it enters the fixed platform 11. When the crucible 5 is in the middle position of the guide roller conveyor 1, it is limited by the other ends of the two sets of guide plates 32 that are parallel to each other, ensuring stable conveying.

[0031] The fixed shell 21 has a rotating disk 24 rotatably installed inside. The front and rear ends of the bottom of the rotating disk 24 are hinged with connecting rods 25, and the connecting rods 25 are located at the eccentric position of the rotating disk 24. The other end of the connecting rods 25 is hinged to the movable plate 23, and the connecting rods 25 are located at the center of the bottom of the movable plate 23.

[0032] When the rotating disk 24 rotates, the connecting rod 25, hinged at the eccentric position of the rotating disk 24, will pull the movable plate 23 inward or open it outward. Furthermore, during the transport of the crucible 5, the operator can simultaneously control the movement of the two sets of movable plates 23 by rotating the rotating disk 24, thereby controlling the distance between the two sets of movable plates 23 to limit the movement path of the crucible. During compaction, the operator can shorten the distance between the two sets of movable plates 23 to clamp the crucible 5 with the two sets of guide plates 32, preventing it from shifting.

[0033] The fixed housing 21 has two sets of brackets 28 fixedly installed inside, and a worm gear 27 is rotatably installed between the two sets of brackets 28. The fixed housing 21 also has a motor 29 fixedly installed inside, and the output shaft of the motor 29 is fixedly connected to the worm gear 27. The bottom of the rotating disk 24 has a worm wheel 26 fixedly installed, and the worm wheel 26 is connected to the worm gear 27 in a transmission connection.

[0034] A worm gear 27 is rotatably mounted between two sets of brackets 28, and one end of the worm gear 27 extends through one set of brackets 28 to be fixedly connected to the output shaft of the motor 29. The operator can drive the worm gear 27 to rotate by operating the motor 29. The rotation of the worm gear 27 will drive the worm wheel 26 connected to it to rotate, thereby driving the rotating disk 24 to rotate.

[0035] The graphitization crucible conveying device of this application further includes a support mechanism 4. The support mechanism 4 includes a fixed base 41 placed on the conveying roller 15. The fixed base 41 is used to support and accommodate the crucible 5. Multiple sets of protruding plates 42 are fixedly installed on the outer wall of the fixed base 41. A rotating rod 43 is rotatably installed between each set of protruding plates 42. A limit block 44 is provided at the top of the rotating rod 43. The multiple sets of limit blocks 44 are used to clamp and limit the crucible 5. For example, there are three sets of protruding plates 42.

[0036] The support mechanism 4 ensures that the crucible 5 can be stably conveyed by the roller conveyor 1. Before conveying, since the bottom of the crucible is relatively smooth, a fixed base 41 is usually set to support the crucible. After the operator places the crucible 5 inside the fixed base 41, the rotating rod 43 is rotated upward to make the limiting block 44 and the outer wall of the crucible 5 fit tightly together and fix the rotating rod 43, thereby clamping and limiting the crucible 5. This device ensures the stability of the crucible 5 during transportation by supporting the outer wall of the crucible 5, further preventing the spillage of hot materials and improving safety performance.

[0037] The outer wall of the rotating rod 43 is provided with a fixing hole 45, which is located on one side of the rotating shaft of the rotating rod 43. A pull rod 46 is movably installed on the outer wall of the protruding plate 42. One end of the pull rod 46 passes through the interior of the fixing hole 45. The pull rod 46 and the protruding plate 42 are elastically connected by a spring 47.

[0038] After placing the crucible 5 inside the fixed base 41, the operator pulls the pull rod 46 outward to disengage it from the fixed hole 45. Then, the rotating rod 43 is rotated upward to further bring the limiting block 44 and the outer surface of the crucible 5 into contact. Finally, the operator releases the pull rod 46, allowing it to re-enter the fixed hole 45 through the elastic potential energy of the spring 47, thus completing the fixation of the rotating rod 43.

[0039] The working principle and usage process of this application:

[0040] The operator first starts the roller conveyor 1. At this time, the pre-loaded equipment fills the inside of the crucible 5 with material. Then, the crucible 5 is transported by the rotation of the conveyor roller 15. The crucible 5 will immediately enter the inside of the fixed platform 11. The guide plate 32 limits the crucible 5 to be in the center position inside the fixed platform 11. When the crucible 5 moves to the bottom of the compaction plate 14, the operator starts the cylinder 13 to make the compaction plate 14 downward and compact the material inside the crucible 5. After the compaction operation is completed, the operator can start the roller conveyor 1 again for conveying operation. After the above steps, the crucible 5 will be guided by the guide plate 32 to ensure the stability of the conveying, and the compaction plate 14 will prevent the material from spilling.

[0041] The operator can drive the worm gear 27 to rotate by operating the motor 29. The rotation of the worm gear 27 will drive the worm wheel 26 connected to it to rotate, and further rotate the rotating disk 24. As the rotating disk 24 rotates, the connecting rod 25, which is hinged to the eccentric position of the rotating disk 24, will pull the movable plate 23 inward or open the movable plate 23 outward. Furthermore, during the transportation of the crucible 5, the operator can limit the movement path of the crucible by controlling the distance between the two sets of movable plates 23. And during the compaction operation, the operator can shorten the distance between the two sets of movable plates 23 to make the two sets of guide plates 32 clamp the crucible 5 and prevent it from shifting.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
