Description

Technical Field

[0001] The utility model relates to the technical field of crucible transportation, and particularly relates to a conveying device for feeding a crucible. Background Art

[0002] When graphitizing battery materials, it is necessary to add battery material powder into the crucible and compact it. First, a certain weight of powder is weighed on a weighing device, then transferred to the crucible feeding position, the weighed powder is added into the crucible, and then transferred to the next working station.

[0003] In the prior art, the crucible is usually transported by rollers and stops at the feeding station. Due to the smooth lower surface of the crucible, when the driving mechanism drives the rollers to brake, the crucible usually moves forward for a certain distance due to inertia. Then, the feeding pipe at the feeding station cannot be aligned with the center point of the crucible, and sometimes even partially deviates from the range of the crucible, resulting in uneven powder in the crucible, leading to a reduction in product effect due to the replenishment of powder in the crucible during subsequent processing. Since the powder has poor fluidity, if the powder overflows or is scattered due to the feeding pipe deviating from the range of the crucible, it will cause environmental pollution and does not meet the minimum dust content regulations. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a conveying device for feeding a crucible, aiming to solve the technical problems mentioned in the background art.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions:

[0006] A conveying device for feeding a crucible includes a conveying mechanism, a lifting mechanism located at a partial section of the conveying mechanism, and a feeding mechanism located above the lifting mechanism. The lifting mechanism includes a lifting component, a support plate fixedly connected to the lifting component, and a plurality of first rollers rotatably arranged in the support plate. The feeding mechanism includes an enclosing cylinder and a feeding pipe located in the enclosing cylinder. The annular top wall of the side of the enclosing cylinder close to the conveying mechanism is arranged as a wedge-shaped surface, and the wedge-shaped surface is inclined from outside to inside and from bottom to top. The inner diameter of the annular top wall of the side of the enclosing cylinder close to the conveying mechanism is the same as the outer diameter of the crucible.

[0007] According to one aspect of the above technical solution, the conveying mechanism includes a bracket, second rollers spaced in the bracket, and a driving component for driving the second rollers to operate. A gravity sensor is arranged in the bracket at the position of the lifting mechanism.

[0008] According to one aspect of the above technical solution, the driving assembly includes a servo motor connected to one of the second rollers, and a gear set disposed between adjacent second rollers, and the gear set is embedded in the bracket.

[0009] According to one aspect of the above technical solution, an accommodating space is formed between the inner wall of the enclosing cylinder and the outer wall of the feeding pipe. A dust treatment mechanism is provided on the enclosing cylinder. The dust treatment mechanism includes a dust collector disposed above the enclosing cylinder, and a dust pipe penetrating through the enclosing cylinder, and the dust pipe is connected to the dust collector.

[0010] According to one aspect of the above technical solution, a storage bin is provided above the enclosing cylinder, and the feeding pipe penetrates through the enclosing cylinder and extends into the storage bin.

[0011] According to one aspect of the above technical solution, the crucible feeding and conveying device further includes a detection mechanism. The detection mechanism includes a vertical telescopic rod, a horizontal telescopic rod connected to the vertical telescopic rod, and a pressing plate located below the horizontal telescopic rod, and a pressure sensor is provided in the pressing plate.

[0012] According to one aspect of the above technical solution, the size of the pressing plate is the same as the inner size of the crucible.

[0013] According to one aspect of the above technical solution, an avoidance groove for avoiding the first roller is provided on the bracket.

[0014] According to one aspect of the above technical solution, the crucible feeding and conveying device further includes a support frame, and a clamping member is provided on the support frame, and the clamping member is used for clamping the enclosing cylinder.

[0015] According to one aspect of the above technical solution, the lifting assembly includes a hydraulic cylinder and an elastic member connected to the support plate. The hydraulic cylinder includes a cylinder body and a hydraulic rod connected to the cylinder body. A through hole for slidably connecting the hydraulic rod is provided on the support plate, and the elastic member is disposed between the cylinder body and the support plate.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] By arranging a jacking mechanism at a partial section of the conveying mechanism and arranging a feeding mechanism above the jacking mechanism, when the crucible is transported from the conveying mechanism to the jacking mechanism, the conveying mechanism will stop. Since the surface of the crucible is smooth, the crucible will move forward a small distance. At this time, the jacking mechanism is started to lift the crucible so that the crucible contacts the wedge-shaped surface of the annular top wall on the enclosing cylinder. Due to the special shape of the wedge-shaped surface, when the crucible contacts the wedge-shaped surface, it will move towards the inside of the enclosing cylinder along the direction of the wedge-shaped surface. Since the inner diameter of the enclosing cylinder is the same as the outer diameter of the crucible, the crucible will completely enter the enclosing cylinder, thus completing the alignment of the crucible, enabling the feeding pipe to feed exactly at the center of the crucible, preventing powder from spilling. At this time, the enclosing cylinder can also be used to prevent dust from flying, reducing environmental pollution. Since the crucible is located on the first roller, the crucible can move more smoothly when contacting and moving along the wedge-shaped surface, preventing the crucible from getting stuck due to excessive friction.

[0026]

[0027]

[0028] The following specific embodiments will further illustrate the present invention in conjunction with the above drawings. SPECIFIC EMBODIMENTS

[0029] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] Please refer to Figures 1 to 7 , which shows a conveying device for crucible feeding in an embodiment of the present utility model, including a conveying mechanism 10, a lifting mechanism 20 located at a partial section of the conveying mechanism 10, and a feeding mechanism 40 located above the lifting mechanism 20. The lifting mechanism 20 includes a lifting assembly, a support plate 23 fixedly connected to the lifting assembly, and a plurality of first rollers 24 rotatably provided in the support plate 23. The feeding mechanism 40 includes an enclosing cylinder 41 and a feeding pipe 44 located in the enclosing cylinder 41. The annular top wall 46 of the enclosing cylinder 41 on the side close to the conveying mechanism 10 is provided as a wedge surface 47, and the wedge surface 47 is inclined from outside to inside and from bottom to top. The inner diameter of the annular top wall 46 of the enclosing cylinder 41 on the side close to the conveying mechanism 10 is the same as the outer diameter of the crucible 30.

[0033] It can be understood that in the present utility model, a jacking mechanism 20 is provided at a partial section of the conveying mechanism 10, and a feeding mechanism 40 is provided above the jacking mechanism 20. When the crucible 30 is transported from the conveying mechanism 10 to the jacking mechanism 20, the conveying mechanism 10 will stop. Since the surface of the crucible 30 is smooth, the crucible 30 will move forward a small distance. At this time, the jacking mechanism 20 is started to lift the crucible 30 so that the crucible 30 contacts the wedge surface 47 of the annular top wall 46 on the enclosing cylinder 41. Due to the special shape of the wedge surface 47, when the crucible 30 contacts the wedge surface 47, it will move towards the inside of the enclosing cylinder 41 along the direction of the wedge surface 47. Since the inner diameter of the enclosing cylinder 41 is the same as the outer diameter of the crucible 30, the crucible 30 will completely enter the enclosing cylinder 41. In this way, the alignment of the crucible 30 is completed, enabling the feeding pipe 44 to discharge materials exactly at the center of the crucible 30, preventing powder from spilling. At this time, the enclosing cylinder 41 can also be used to prevent dust from flying, reducing environmental pollution. Since the crucible 30 is located on the first roller 24, when the crucible 30 contacts and moves along the wedge surface 47, it can move more smoothly, preventing the crucible 30 from getting stuck due to excessive friction.

[0034] Specifically, in this embodiment, the conveying mechanism 10 includes a bracket 11, second rollers 12 spaced in the bracket 11, and a driving component for driving the second rollers 12 to operate. A gravity sensor is provided in the bracket 11 at the jacking mechanism 20; the driving component includes a servo motor 13 connected to one of the second rollers 12 and a gear set (located inside the bracket 11 and not shown in the figure) provided between adjacent second rollers 12, and the gear set is buried in the bracket 11.

[0035] It can be understood that when it is necessary to load the crucible 30, the crucible 30 is placed on the first roller 24, the servo motor 13 is started, and the first roller 24 is driven to rotate through the gear set, enabling the crucible 30 to move on the first roller 24. When the crucible 30 moves to the jacking mechanism 20, since the crucible 30 is still located on the first roller 24 at this time, the first roller 24 at this position will transmit the force to the gravity sensor in the bracket 11. At this time, the servo motor 13 stops rotating. Due to inertia, the crucible 30 will still move forward a certain distance, so the opening of the crucible 30 is not directly below the opening of the enclosing cylinder 41; the lifting component starts to move, driving the support plate 23 and the first roller 24 to lift the crucible 30. The crucible 30 will first contact the wedge surface 47. When the crucible 30 continues to rise, the wedge surface 47 will squeeze the crucible 30 towards the inside of the enclosing cylinder 41 until the crucible 30 completely enters the inside of the enclosing cylinder 41. The enclosing cylinder 41 can prevent powder from spilling from the opening of the crucible 30 during feeding.

[0036] Furthermore, the lifting assembly includes a hydraulic cylinder 27 and an elastic member 22 connected to the support plate 23. The hydraulic cylinder 27 includes a cylinder block 21 and a hydraulic rod 25 connected to the cylinder block 21. The support plate 23 is provided with a through hole 26 slidably connected to the hydraulic rod 25. The elastic member 22 is disposed between the cylinder block 21 and the support plate 23. An avoidance groove 14 for avoiding the first roller 24 is provided on the bracket 11.

[0037] It can be understood that the hydraulic cylinder 27 can drive the support plate 23 and the first roller 24 to rise together to lift the crucible 30. When the crucible 30 contacts the wedge surface 47, the crucible 30 will move towards the inside of the enclosure cylinder 41. The function of the elastic member 22 is to prevent the crucible 30 from cracking when it is forced to be pushed towards the wedge surface 47 when the frictional force is slightly large. Therefore, the elastic member 22 is provided. When the crucible 30 cannot move for a moment, the elastic member 22 will be compressed, and the hydraulic rod 25 will slide along the through hole 26 to give the crucible 30 a buffering force, so that the crucible 30 can break away from the dead point with a slightly larger frictional force at the first roller 24 and smoothly slide into the inside of the enclosure cylinder 41.

[0038] Furthermore, an accommodation space 48 is formed between the inner wall of the enclosure cylinder 41 and the outer wall of the feeding pipe 44. A dust treatment mechanism is provided on the enclosure cylinder 41. The dust treatment mechanism includes a dust collector 43 provided above the enclosure cylinder 41 and a dust pipe 49 penetrating through the enclosure cylinder 41. The dust pipe 49 is connected to the dust collector 43. A storage bin 50 is provided above the enclosure cylinder 41. The feeding pipe 44 penetrates through the enclosure cylinder 41 and extends into the storage bin 50.

[0039] It can be understood that after the enclosure cylinder 41 covers the crucible 30, feeding can begin. The powder is delivered from the feeding pipe 44 to the crucible 30 through the storage bin 50. Since the fluidity of the powder is poor, part of the dust will adhere to the accommodation space 48. After the feeding is completed and the crucible 30 is separated from the enclosure cylinder 41, the dust collector 43 can be started to suck the dust in the accommodation space 48 through the dust pipe 49 to prevent the dust from falling due to gravity and causing environmental pollution.

[0040] Furthermore, the crucible feeding conveying device further includes a detection mechanism 60. The detection mechanism 60 includes a vertical telescopic rod 61, a horizontal telescopic rod 62 connected to the vertical telescopic rod 61, and a pressing plate 63 located below the horizontal telescopic rod 62. A pressure sensor is provided in the pressing plate 63. The size of the pressing plate 63 is the same as the inner size of the crucible 30.

[0041] It can be understood that due to the poor fluidity of the powder material, after feeding, the powder material in the crucible 30 will be in the shape of a small mountain, high in the middle and low on both sides, and there are many voids inside the powder material. Therefore, after feeding, the crucible 30 needs to be slightly lowered, and then the position of the pressure plate 63 is adjusted through the vertical telescopic rod 61 and the horizontal telescopic rod 62. Since the position of the crucible 30 has been adjusted at the enclosure cylinder 41, the pressure plate 63 does not need to adjust the position in the third axis direction and can just enter the crucible 30 to compact the powder material and conduct a pressure test. After the pressure is qualified, it is transported to the next working station. If it is unqualified, it needs to be fed again and the pressure test is carried out again.

[0042] Further, the conveying device for feeding the crucible further includes a support frame, and a clamping member 42 is provided on the support frame, and the clamping member 42 is used for clamping the enclosure cylinder 41.

[0043] In summary, for the conveying device for feeding the crucible in the above embodiments of the present invention, by providing a jacking mechanism at a partial section of the conveying mechanism and a feeding mechanism above the jacking mechanism, when the crucible is transported from the conveying mechanism to the jacking mechanism, the conveying mechanism will stop. Since the surface of the crucible is smooth, the crucible will move forward a small distance. At this time, the jacking mechanism is started to jack up the crucible so that the crucible contacts the wedge-shaped surface of the annular top wall on the enclosure cylinder. Due to the special shape of the wedge-shaped surface, when the crucible contacts the wedge-shaped surface, it will move towards the inside of the enclosure cylinder along the direction of the wedge-shaped surface. Since the inner diameter of the enclosure cylinder is the same as the outer diameter of the crucible, the crucible will completely enter the enclosure cylinder, thus completing the alignment of the crucible, enabling the feeding pipe to feed exactly into the center of the crucible, preventing the powder material from overflowing. At this time, the enclosure cylinder can also be used to prevent dust from flying, reducing environmental pollution. Since the crucible is located on the first roller, the crucible can move more smoothly when contacting and moving with the wedge-shaped surface, preventing the crucible from being stuck due to excessive friction.
