Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a crucible packaging device. Background Art

[0002] Platinum crucibles are made of platinum. They have a high melting point, very stable chemical properties and do not absorb water. Therefore, they are widely used in chemical analysis, alloy smelting, metal refining, crystal growth and other fields. Among them, in the field of crystal growth, platinum crucibles are usually used as crystal growth containers. After the crystal is placed in the platinum crucible, the platinum crucible is packaged so that the crystal is sealed inside the platinum crucible. In the prior art, the methods of packaging platinum crucibles are generally divided into three categories. One is to package the platinum crucible by manually folding the top of the platinum crucible, one is to package the platinum crucible by laser welding, and the other is to package the platinum crucible by using a sealing cover, a mechanical cover and a mechanical pressure cover. However, when the platinum crucible is packaged by manual folding, it is easy to cause excessive wrinkles in the platinum crucible, and in severe cases, it may even cause damage to the platinum crucible. When the platinum crucible is packaged by laser welding, the welding conditions are strictly required and the packaging cost is relatively high. When a sealing cover, a mechanical cover and a mechanical pressure cover are used together to package a platinum crucible, the sealing cover, the mechanical cover and the mechanical pressure cover need to match the specifications of the platinum crucible and need to form an integral structure with the platinum crucible in order to package the platinum crucible. This leads to poor versatility and high cost. Utility Model Content

[0021] Beneficial effects of the utility model:

[0022] The utility model provides a crucible packaging device for packaging a crucible bag, which is used to hold materials. The crucible packaging device includes a holding tube and a packaging structure. The holding tube is used to hold the crucible bag, and the packaging structure includes a heating ring, a tightening structure, and a folding structure. The heating ring is detachably connected to the top end of the holding tube along the axial direction and can be raised and lowered along the axial direction of the holding tube. The tightening structure includes at least two memory plates, and the at least two memory plates are distributed on the inner circumference of the heating ring at intervals along the circumference of the heating ring. The middle area of ​​each memory plate is slidably connected to the heating ring along the circumference of the heating ring. The folding structure includes two folding rods, which are detachably connected to one end of the heating ring along the axial direction and both extend along the first radial direction of the heating ring; the two folding rods can move closer to or away from each other along the second radial direction of the heating ring and can rotate around a fixed axis; the first radial direction and the second radial direction are perpendicular and both are perpendicular to the axial direction of the heating ring, and the fixed axis is parallel to the first radial direction and is located in the middle of the two folding rods along the second radial direction.

[0023] Place the crucible bag into the holding tube, ensuring that the opening of the crucible bag extends beyond the axial top of the holding tube. After the crucible bag is sufficiently loaded with material, install the heating ring at the axial top of the holding tube. It should be understood that at this point, the opening of the crucible bag is located within the heating ring.

[0024] The heating ring heats the memory chips. Since the middle region of each memory chip is connected to the heating ring, upon heating, the ends of each memory chip along the circumference of the heating ring converge toward the center of the chip, causing each chip to roughly contract into a petal-like shape. As the ends of each memory chip along the circumference of the heating ring converge toward their respective centers, the opening of the crucible bag is simultaneously tightened, forming at least two petal-like structures.

[0025] The at least two memory plates are then slidably adjusted along the circumference of the heating ring so that the at least two memory plates are substantially linearly distributed along the first radial direction and are located directly below the two folding rods along the axial direction of the holding tube. It will be appreciated that the at least two petal-shaped structures formed in the opening area of ​​the crucible bag are also substantially linearly distributed along the first radial direction and are located directly below the two folding rods along the axial direction of the holding tube.

[0026] The two folding rods are then adjusted away from each other along a second radial direction, and the heating ring is adjusted toward the holding tube along an axial direction of the holding tube, so that the at least two petal-shaped structures formed in the opening area of ​​the crucible bag partially extend beyond the end of the heating ring axially away from the holding tube and pass through the gap between the two folding rods.

[0027] Then, the two folding rods are adjusted toward each other along a second radial direction until the opening area of ​​the crucible bag is clamped.

[0028] Then, the two folding rods are rotated around the fixed axis to roll up and package the opening area of ​​the crucible bag.

[0029] After the opening area of ​​the crucible bag is sealed, the two folding rods are detached from the heating ring and the crucible bag is withdrawn along a first radial direction. The heating ring stops heating the memory chip, allowing it to cool and gradually extend to its initial state. The packaging device is then removed from the container. During the cooling process, the spacing of at least two memory chips along the circumference of the heating ring is adjusted so that each memory chip does not contact and / or overlap with adjacent memory chips during its extension to its initial state.

[0030] Thus, using this crucible packaging device to package a crucible bag is simple to operate and effectively prevents excessive wrinkling or even damage to the crucible bag. Furthermore, the crucible packaging device is adaptable to crucible bags of various specifications, effectively improving versatility and reducing costs. Furthermore, once the crucible bag is packaged, the packaging structure can be separated from the crucible bag, making it easy to reuse the packaging structure. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0052] like Figures 1 to 9As shown, the utility model provides a crucible packaging device for packaging a crucible bag 100, and the crucible bag 100 is used to hold materials. The crucible packaging device includes a holding tube 1 and a packaging structure 2. The holding tube 1 is used to hold the crucible bag 100, and the packaging structure 2 includes a heating ring 21, a tightening structure and a folding structure. The heating ring 21 is detachably connected to the top end of the holding tube 1 along the axial direction and can be lifted and lowered along the axial direction of the holding tube 1. The tightening structure includes at least two memory plates 22, and the at least two memory plates 22 are distributed on the inner circumference of the heating ring 21 at intervals along the circumference of the heating ring 21. The middle area of ​​each memory plate 22 is slidably connected to the heating ring 21 along the circumference of the heating ring 21. The folding structure includes two folding rods 23, which are detachably connected to one end of the heating ring 21 along the axial direction and both extend along the first radial direction of the heating ring 21; the two folding rods 23 can approach or move away from each other along the second radial direction of the heating ring 21 and can rotate around a fixed axis; the first radial direction and the second radial direction are perpendicular and both are perpendicular to the axial direction of the heating ring 21, and the fixed axis is parallel to the first radial direction and is located in the middle of the two folding rods 23 along the second radial direction.

[0053] Place the crucible bag 100 into the container 1, ensuring that the opening of the crucible bag 100 extends beyond the axial top of the container 1. After the crucible bag 100 is sufficiently filled with material, the heating ring 21 is installed at the axial top of the container 1. It should be understood that at this point, the opening of the crucible bag 100 is located within the heating ring 21.

[0054] The heating ring 21 heats the memory sheets 22. Since the central region of each memory sheet 22 is connected to the heating ring 21, upon heating, the ends of each memory sheet 22 along the circumference of the heating ring 21 converge toward the center of the sheet 22, causing each memory sheet 22 to roughly contract into a petal-like shape. As the ends of each memory sheet 22 along the circumference of the heating ring 21 converge toward their respective centers, the opening of the crucible bag 100 is simultaneously contracted, forming at least two petal-like structures.

[0055] The at least two memory plates 22 are then slidably adjusted along the circumference of the heating ring 21 so that the at least two memory plates 22 are substantially linearly distributed along the first radial direction and are located directly below the two folding rods 23 along the axial direction of the holding tube 1. It will be appreciated that the at least two petal-shaped structures formed in the opening area of ​​the crucible bag 100 are also substantially linearly distributed along the first radial direction and are located directly below the two folding rods 23 along the axial direction of the holding tube 1.

[0056] The two folding rods 23 are then adjusted away from each other along the second radial direction, and the heating ring 21 is adjusted axially toward the containing cylinder 1 so as to be closer to the containing cylinder 1. This ensures that the at least two petal-shaped structures formed in the opening area of ​​the crucible bag 100 partially extend from the end of the heating ring 21 axially away from the containing cylinder 1 and pass through the gap between the two folding rods 23.

[0057] The two folding rods 23 are then adjusted toward each other along the second radial direction until the opening area of ​​the crucible bag 100 is clamped.

[0058] The two folding rods 23 are then rotated around the fixed axis to roll up and package the opening area of ​​the crucible bag 100 .

[0059] After sealing the opening area of ​​the crucible bag 100, the two folding rods 23 are detached from the heating ring 21 and the crucible bag 100 is withdrawn along the first radial direction. The heating ring 21 stops heating the memory sheet 22, allowing the memory sheet 22 to cool and gradually extend to its initial state. The packaging device is then removed from the container 1. During the cooling process, the spacing of at least two memory sheets 22 along the circumference of the heating ring 21 is adjusted so that each memory sheet 22 contacts and / or overlaps with an adjacent memory sheet 22 as it extends to its initial state.

[0060] Thus, using this crucible packaging device to package the crucible bag 100 is simple to operate and effectively prevents excessive wrinkling or even damage to the crucible bag 100. Furthermore, this crucible packaging device is adaptable to crucible bags 100 of various specifications, effectively improving versatility and reducing costs. Furthermore, once the crucible bag 100 is packaged, the packaging structure 2 can be separated from the crucible bag 100, facilitating reuse of the packaging structure 2.

[0061] Preferably, in this embodiment, Figure 4 As shown, after the heating ring 21 is detachably connected to the top axial end of the container 1, the heating ring 21 can axially abut the top axial end surface of the container 1. The central axis of the container 1 and the central axis of the heating ring 21 are collinear. The inner diameter of the container 1 is equal to the aperture of the heating ring 21.

[0062] As an alternative, after the heating ring 21 is detachably connected to the top axial end of the container 1, the heating ring 21 can be placed around the outer circumference of the top axial end of the container 1. The central axis of the container 1 and the central axis of the heating ring 21 are collinear. The aperture of the heating ring 21 is greater than or equal to the outer diameter of the container 1.

[0063] Preferably, in this embodiment, Figure 7-9 As shown, the first radial direction and the second radial direction are perpendicular and both intersect the central axis of the heating ring at right angles. The fixed axis intersects the central axis of the heating ring at right angles. This can further improve the quality of wrapping the opening area of ​​the crucible bag 100.

[0064] In this embodiment, the crucible bag 100 is exemplarily configured as a platinum crucible bag, which is made of platinum with a purity exceeding 99%, a melting point of 1772° C., and is chemically very stable and does not absorb water.

[0065] In this embodiment, the thickness of the platinum crucible bag is exemplarily set to range from 0.1 mm to 0.2 mm.

[0066] It is understood that while the heating ring 21 is heating the memory chip 22, it also simultaneously heats the opening area of ​​the crucible bag 100. Specifically, for a platinum crucible bag, the yield strength of the platinum crucible bag decreases when heated. Therefore, rotating the two folding rods 23 around the fixed axis to wrap and seal the opening area of ​​the crucible bag 100 effectively reduces the difficulty of winding the crucible bag 100, facilitates adjusting the number of winding turns based on sealing requirements, and further reduces the risk of excessive wrinkling or even damage to the crucible bag 100. This further improves the quality of the wrapping and sealing of the opening area of ​​the crucible bag 100 and effectively increases the service life of the crucible bag 100.

[0067] In this embodiment, the memory sheet 22 is exemplarily configured as a titanium-nickel alloy sheet. Nickel accounts for 55% to 56% of the titanium-nickel alloy sheet, and titanium accounts for 44% to 45%. Because the thinner the memory sheet 22, the greater the bending curvature, the thickness of the titanium-nickel alloy sheet is set to a range of 0.2 mm to 0.5 mm. This allows the memory sheet 22 to effectively tighten into a roughly petal-like shape when heated. The resulting titanium-nickel alloy sheet has a tensile strength of 800 Pa to 1000 Pa, and a toughness of ≥80 J / cm².

[0068] Specifically, the packaging length of the crucible bag 100 is generally set to be greater than or equal to 10 cm to ensure the packaging reliability of the crucible bag 100. Taking a platinum crucible bag with a diameter of 13 cm as an example, the packaging length of the platinum crucible bag is greater than or equal to 15 cm.

[0069] Among them, Figures 2 to 4 As shown, the heating ring 21 includes an insulating ring body 211 and an electric heater 212. The electric heater 212 is fixed to the insulating ring body 211. The electric heater 212 is an electromagnetic coil wound around the insulating ring body 211. Alternatively, the electric heater 212 is a resistance wire wound around the insulating ring body 211. This allows the ends of the heating ring 21 along the circumference of the memory plate 22 to be heated, with both ends converging toward the center of the memory plate 22.

[0070] Preferably, in this embodiment, Figure 2-4 As shown, the electric heater 212 is wound around the interior of the insulating ring body 211. As an alternative, the electric heater 212 is wound around the inner circumference of the insulating ring body 211, and at least two memory chips 22 are located on the inner circumference of the electric heater 212. As another alternative, the electric heater 212 is wound around the outer circumference of the insulating ring body 211.

[0071] Specifically, the crucible packaging device also includes a power supply electrically connected to the electric heater 212. The power supply can provide electrical energy to the electric heater 212. Furthermore, the power supply can be integrated into the heating ring 21; or, the power supply can be an external power source remote from the heating ring 21 and electrically connected to the electric heater 212 via leads.

[0072] Specifically, in this embodiment, after the power supply is electrically connected to the electric heater 212, the heating rate of the electric heater 212 is 3°C / min. After the power supply is turned off, the cooling rate of the electric heater 212 is also 3°C / min.

[0073] Preferably, the folding rod 23 is electrically heated. An electromagnetic coil or resistance wire is disposed within the folding rod 23. Both the electromagnetic coil and resistance wire can be electrically connected to a power source. Heating the folding rod 23 during winding and encapsulating the opening of the crucible bag 100 can further reduce the difficulty of winding the crucible bag 100, further facilitate adjusting the number of winding turns based on sealing requirements, and further reduce the risk of excessive wrinkling or even damage to the crucible bag 100, thereby further extending the service life of the crucible bag 100.

[0074] Preferably, if Figure 5 and Figure 6 As shown, along the axial direction of the heating ring 21, from the end close to the holding cylinder 1 to the end away from the holding cylinder 1, the distance between the two ends of the memory sheet 22 along the circumferential direction of the heating ring 21 gradually decreases. It can be understood that such a configuration can not only effectively tighten the opening area of ​​the crucible bag 100 to form at least two petal-shaped structures, but also effectively reduce the contact area between the memory sheet 22 and the crucible bag 100, thereby further avoiding the risk of the memory sheet 22 scratching or even breaking the crucible bag 100 during the process of adjusting the heating ring 21 along the axial direction of the holding cylinder 1 to approach the holding cylinder 1. Secondly, during the process of adjusting the heating ring 21 along the axial direction of the holding cylinder 1 to approach the holding cylinder 1, it is also convenient for the crucible bag 100 and the material in the crucible bag 100 to stretch the two ends of the memory sheet 22 along the circumferential direction of the heating ring 21, so that the memory sheet 22 can initially stretch.

[0075] Specifically, the distance between the circumferential ends of the memory sheet 22 along the heating ring 21 gradually decreases from the end closest to the holding cylinder 1 to the end further away from the holding cylinder 1 along the axial direction of the heating ring 21. Furthermore, the end of the memory sheet 22 axially closer to the holding cylinder 1 along the heating ring 21 is closer to the material in the crucible bag 100. Therefore, after the memory sheet 22 is heated, the bending angle of the end of the memory sheet 22 axially farther from the holding cylinder 1 along the heating ring 21 is greater than or equal to the bending angle of the end of the memory sheet 22 axially closer to the holding cylinder 1 along the heating ring 21. This further reduces the risk of the memory sheet 22 scratching or even breaking the crucible bag 100 during the process of adjusting the heating ring 21 axially toward the holding cylinder 1.

[0076] Specifically, in this embodiment, Figure 2 、 Figure 3 and Figure 7 As shown, when the memory sheet 22 is not heated, the memory sheet 22 is in an arc shape. Figure 5 、 Figure 6 and Figure 8 As shown, when the memory sheet 22 is heated, both ends of the memory sheet 22 along the circumference of the heating ring 21 will move closer to the middle of the memory sheet 22, so that the memory sheet 22 is roughly tightened into a petal shape.

[0077] Preferably, if Figures 5 to 9 As shown, when there are multiple memory sheets 22, the number of memory sheets 22 is an even number. Accordingly, the number of petal-shaped structures formed in the opening area of ​​the crucible bag 100 is also an even number. Dividing the even number of petal-shaped structures into two equal parts and adjusting them to be distributed roughly linearly along the first radial direction facilitates the insertion of the multiple petal-shaped structures through the gap between the two folding rods 23 and ensures that the thickness of the wound structure is roughly uniform, thereby further improving the quality of the wound packaging of the opening area of ​​the crucible bag 100.

[0078] As an alternative, when there are multiple memory slices 22 , the number of the memory slices 22 is an odd number.

[0079] In this embodiment, if Figures 5 to 9 As shown, the exemplary number of memory plates 22 is four. The four memory plates 22 are spaced apart along the circumference of the heating ring 21 and distributed on the inner circumference of the heating ring 21. When the memory plates 22 are not heating, the four memory plates 22 are preferably evenly spaced apart along the circumference of the heating ring 21.

[0080] Specifically, Figure 7 The four memory pieces 22 are all in an initial state, extending into an arc shape. Figure 5 、 Figure 6 and Figure 8 The four memory sheets 22 are all tightened into petal shapes. Figure 9 The four memory pieces 22 are all tightened into a petal shape, and the four memory pieces 22 are evenly divided into two parts and are roughly distributed in a straight line along the first radial direction.

[0081] Among them, Figure 2 、 Figure 3 and Figures 5 to 9As shown, the tightening structure further includes at least two first sliding connectors 24, which are provided in a one-to-one correspondence with the at least two memory plates 22. Each first sliding connector 24 passes through the heating ring 21 and is fixedly connected to the corresponding memory plate 22. Each first sliding connector 24 is slidably connected to the heating ring 21 along the circumference of the heating ring 21. Specifically, the first sliding connector 24 is slidably connected to the insulating ring body 211 along the circumference of the heating ring 21.

[0082] When the memory sheets 22 are not heated, the first sliding connector 24 allows for quick and easy adjustment of the multiple memory sheets 22 to be evenly spaced along the circumference of the heating ring 21. When the memory sheets 22 are heated and tightened into a petal-like shape, the first sliding connector 24 allows for quick and easy adjustment of the multiple memory sheets 22 to be divided into two and distributed approximately in a straight line along the first radial direction, thereby effectively improving packaging efficiency.

[0083] Specifically, if Figure 5 and Figure 6 As shown, the heating ring 21 is provided with at least two first sliding holes 2111 distributed along the circumference. Each first sliding hole 2111 connects the interior of the heating ring 21 with the exterior of the heating ring 21 and extends along the circumference of the heating ring 21. The first sliding holes 2111 are used to mount the first sliding connector 24 and guide the first sliding connector 24 to move along the circumference of the heating ring 21. Specifically, the first sliding holes 2111 are formed in the insulating ring body 211, thereby enabling the first sliding connector 24 to slide along the circumference of the heating ring 21.

[0084] Specifically, in this embodiment, Figure 2 、 Figure 3 and Figures 5 to 9 As shown, the exemplary arrangement includes two first sliding holes 2111, with the two first sliding holes 2111 evenly spaced along the circumference of the heating ring 21. The two ends of the folding rod 23 along the length direction are respectively located in the middle region of the two first sliding holes 2111 along the circumference. Each first sliding hole 2111 corresponds to two first sliding connectors 24. When the two first sliding connectors 24 corresponding to each first sliding hole 2111 are respectively located at the two ends of the corresponding first sliding hole 2111 along the circumference, the four memory plates 22 are evenly spaced along the circumference of the heating ring 21. When the memory plates 22 are heated and tightened into a petal shape, and the two first sliding connectors 24 corresponding to each first sliding hole 2111 are both located in the middle region of the corresponding first sliding hole 2111 along the circumference, the four memory plates 22 are roughly distributed in a straight line along the first radial direction.

[0085] Among them, Figure 1As shown, a first lifting mechanism 3 is provided on the outer periphery of the top end of the containing cylinder 1 along the axial direction. The output end of the first lifting mechanism 3 is detachably connected to the heating ring 21. The first lifting mechanism 3 can drive the heating ring 21 to rise and fall along the axial direction of the containing cylinder 1.

[0086] Specifically, the first lifting mechanism 3 is an electric push rod; or, the first lifting mechanism 3 is a telescopic rod, etc., which can drive the heating ring 21 to move up and down along the axial direction of the container 1. The specific structures of the electric push rod and the telescopic rod are all prior art and will not be described in detail here.

[0087] Specifically, one of the output end of the first lifting mechanism 3 and the end of the heating ring 21 axially closer to the container 1 is provided with a slot, and the other is provided with a post. The slot and the post engage with each other, allowing the heating ring 21 to be detachably connected to the top axial end of the container 1 and to be raised and lowered along the axial direction of the container 1. As an alternative, the output end of the first lifting mechanism 3 and the heating ring 21 can also be detachably connected using a threaded connection or a snap-fit ​​connection.

[0088] Optionally, there are multiple first lifting mechanisms 3 , which are spaced apart along the circumference of the containing cylinder 1 , so as to improve the stability of driving the heating ring 21 to move up and down along the axial direction of the containing cylinder 1 .

[0089] Optionally, one of the outer circumferential wall of the holding cylinder 1 and the inner circumferential wall of the insulating ring body 211 is provided with a first guide rail extending in the axial direction, and the other is provided with a first guide block, and the first guide rail and the first guide block are slidably engaged with each other to improve the smoothness of the axial lifting and lowering of the heating ring 21 along the holding cylinder 1.

[0090] Among them, Figure 1 and Figure 4 As shown, the crucible packaging device also includes a vibration material structure 4, which includes a vibration material plate 41 and an elastic member 42 located in the holding tube 1. One end of the elastic member 42 is fixedly connected to the vibration material plate 41, and the other end of the elastic member 42 is fixedly connected to the inner bottom wall of the holding tube 1. The vibration material plate 41 is used to support the crucible bag 100. The vibration material structure 4 also includes a second sliding connection member 43 and a locking member 44. The second sliding connection member 43 passes through the holding tube 1 and is fixedly connected to the vibration material plate 41. The second sliding connection member 43 can be raised and lowered along the axial direction of the holding tube 1, and the locking member 44 can lock the relative position of the second sliding connection member 43 and the holding tube 1.

[0091] During the process of placing material into the crucible bag 100, the relative position of the second sliding connector 43 and the holding tube 1 is unlocked by the locking member 44. The elastic restoring force of the elastic member 42 causes the vibration plate 41, the second sliding connector 43, the crucible bag 100, and the material in the crucible bag 100 to vibrate synchronously along the axial direction of the holding tube 1, thereby ensuring a dense and even distribution of the material within the crucible bag 100. When the material is not being vibrated, the relative position of the second sliding connector 43 and the holding tube 1 is locked by the locking member 44.

[0092] Specifically, in this embodiment, the locking member 44 is exemplarily configured as a locking nut, which is threadedly connected to the portion of the second sliding connector 43 that extends out of the receiving tube 1. To lock the relative position of the second sliding connector 43 and the receiving tube 1, the locking nut is rotated in a first clockwise direction so that the second sliding connector 43 abuts against the outer circumferential wall of the receiving tube 1, thereby locking the relative position of the second sliding connector 43 and the receiving tube 1. To unlock the relative position of the second sliding connector 43 and the receiving tube 1, the locking nut is rotated in a second clockwise direction so that the second sliding connector 43 separates from the outer circumferential wall of the receiving tube 1, thereby unlocking the relative position of the second sliding connector 43 and the receiving tube 1. The first clockwise direction and the second clockwise direction are opposite.

[0093] Specifically, if Figure 1 and Figure 4 As shown, the holding tube 1 is provided with a second sliding hole 11 extending axially, through which a second sliding connector 43 passes, fixedly connected to the vibrating plate 41. This allows the second sliding connector 43 to be raised and lowered along the axial direction of the holding tube 1. In this embodiment, when the second sliding connector 43 is located at the lowest end of the second sliding hole 11 along the axial direction of the holding tube 1, the locking member 44 locks the relative position of the second sliding connector 43 and the holding tube 1, allowing the vibrating plate 41 to stably and reliably support the crucible bag 100 and the material therein.

[0094] Specifically, if Figure 4 As shown, the elastic member 42 is a spring, which has low cost and good elastic supporting performance.

[0095] Among them, such as Figure 1 As shown, the crucible packaging device also includes a base 51 and at least two second lifting mechanisms 52. The at least two second lifting mechanisms 52 are spaced apart from the base 51 along a first horizontal direction. The output end of each second lifting mechanism 52 is rotatably connected to the holding tube 1. This allows the holding tube 1 to be tilted to a desired angle based on actual needs, facilitating loading of materials into the crucible bag 100.

[0096] Alternatively, as Figure 1As shown, the base 51 is provided with a second guide rail 511 extending along a first horizontal direction, and each second lifting mechanism 52 is provided with a second guide block 521. The second guide block 521 slides along the first horizontal direction and rests on the second guide rail 511. This allows the distribution of the at least two second lifting mechanisms 52 along the first horizontal direction to be adaptively adjusted according to the different specifications of the holding tubes 1, thereby further enhancing the versatility of the crucible packaging device.

[0097] like Figure 1 As shown, when there are multiple second lifting mechanisms 52, the multiple second lifting mechanisms 52 can optionally be divided into two groups, with two second guide rails 511. The two groups of second lifting mechanisms 52 are provided with a one-to-one correspondence between the two second guide rails 511. The two second guide rails 511 are spaced apart and distributed on both sides of the storage drum 1 along the second horizontal direction, with the first horizontal direction being perpendicular to the second horizontal direction. The second guide blocks 521 of one group of second lifting mechanisms 52 each slide onto the corresponding second guide rail 511, while the second guide blocks 521 of the other group of second lifting mechanisms 52 each slide onto the corresponding second guide rail 511. This improves the stability of adjusting the tilt of the storage drum 1.

[0098] In this embodiment, if Figure 1 As shown, the exemplary number of the second lifting mechanisms 52 is six, and the six second lifting mechanisms 52 are divided into two groups. The exemplary six second lifting mechanisms 52 can be used together to adjust the tilt of the container 1 by 15° to 30°.

[0099] Specifically, the second lifting mechanism 52 is an electric push rod; or, the second lifting mechanism 52 is a telescopic rod, etc. The container 1 can be tilted to a desired angle according to actual needs.

[0100] Preferably, an elastic cushion is provided on at least the portion of the inner wall of the holding tube 1 that contacts the crucible bag 100 , so as to avoid the risk of oxide materials, contaminants, etc. caused by the inner wall of the holding tube 1 scratching or even breaking the crucible bag 100 .

[0101] Preferably, at least the portion of the vibration plate 41 that contacts the crucible bag 100 is provided with an elastic cushion layer to avoid the risk of the vibration plate 41 scratching or even breaking the crucible bag 100 and causing oxide materials, contaminants, and the like.

[0102] In this embodiment, the elastic cushion layer is exemplarily provided as foam. In other embodiments, the elastic cushion layer can also be provided as sponge or cotton cloth.

[0103] Among them, Figure 2 、 Figure 3 and Figures 5 to 10As shown, the folding structure further includes a support 25 fixedly connected to the outer periphery of the insulating ring body 211, and an adjustment mechanism 26 rotatably connected to the support 25 about a fixed axis. The adjustment mechanism 26 is capable of driving the two folding rods 23 toward or away from each other along the second radial direction, and can also drive the two folding rods 23 to rotate about the fixed axis. Specifically, after the adjustment mechanism 26 drives the two folding rods 23 toward each other along the second radial direction and clamps the opening area of ​​the crucible bag 100, the adjustment mechanism 26 drives the two folding rods 23 to rotate about the fixed axis, wrapping and encapsulating the opening area of ​​the crucible bag 100.

[0104] Specifically, in this embodiment, Figure 2 、 Figure 3 and Figures 5 to 10 As shown, the adjustment mechanism 26 includes a rotating base 261 and an adjusting bolt 262. The rotating base 261 is rotatably connected to the support 25 about a fixed axis. The rotating base 261 is provided with a third sliding hole 2611 extending in the second radial direction. Both folding rods 23 are inserted into the third sliding hole 2611. The adjusting bolt 262 is rotatably connected to the rotating base 261 and extends in the second radial direction. The adjusting bolt 262 is threadedly connected to one of the folding rods 23 and can move the other folding rod 23 along the length of the third sliding hole 2611. Specifically, when the adjusting bolt 262 is rotated in the third clockwise direction, the adjusting bolt 262 moves the one folding rod 23 closer to the other folding rod 23 in the second radial direction. When the adjusting bolt 262 is rotated in the fourth clockwise direction, the adjusting bolt 262 moves the one folding rod 23 away from the other folding rod 23 in the second radial direction, thereby adjusting the two folding rods 23 to move closer to or further away from each other. After clamping the opening area of ​​the crucible bag 100, the rotating seat 261 is rotated to drive the two folding rods 23 to wrap and seal the opening area of ​​the crucible bag 100. The third clockwise direction is opposite to the fourth clockwise direction.

[0105] Alternatively, as Figure 2 、 Figure 3 and Figures 5 to 9 As shown, there are two supports 25 and two adjustment mechanisms 26, each corresponding to a one-to-one relationship. The two supports 25 are located at either end of the folding rod 23 along its length. Correspondingly, the two adjustment mechanisms 26 are located at either end of the folding rod 23 along its length. Two adjustment bolts 262 are threadedly connected to the two folding rods 23 in a one-to-one relationship. This further improves the efficiency of adjusting the two folding rods 23 toward or away from each other, thereby further improving packaging efficiency.

[0106] Alternatively, as Figure 10 As shown, each adjusting bolt 262 is threadedly connected to a corresponding folding rod 23 and rotatably penetrates the other folding rod 23. It can effectively increase the stroke of driving the folding rod 23 to move along the second radial direction.

[0107] Optionally, the rotating seat 261 and the support 25 are connected via a bearing, which can improve the smoothness and stability of the adjustment mechanism 26 rotating around the fixed axis.

[0108] It is understandable that other adjustment mechanisms 26 may also be used to adjust the two folding rods 23 to move closer to or farther from each other, and to adjust the two folding rods 23 to rotate around a fixed axis.
