Description

Technical Field

[0001] This invention relates to the technical field of mixed powder production equipment, and in particular to a sealing device for a sintering crucible for mixed powder and an integrated vibratory leveling and conveying device. Background Technology

[0002] The mixed powder refers to a mixture of nickel cobalt manganese hydroxide and lithium salt. Before the sintering process of the mixed powder, the prepared mixed powder needs to be placed in a sagger, and then the mixed powder in the sagger needs to be vibrated and leveled to ensure the uniformity of the mixed powder, so as to ensure the consistency of the quality of the cathode material obtained by subsequent sintering.

[0003] The sagger has an open opening for holding the mixed powder. Saggers are divided into flat-mouthed saggers and notched saggers. The flat-mouthed sagger includes a first holding section for holding the mixed powder, and the side walls of the first holding section have no notches.

[0004] The notched sagger includes a second holding part and a stacking part connected together. The stacking part is located above the second holding part. When the stacking part is connected to the second holding part, a side wall notch is formed on the side wall, such as an inverted trapezoidal notch or an arc notch. The side wall notch communicates with the opening of the notched sagger. When two notched saggers are stacked vertically, one notched sagger is stacked on the opening of the other notched sagger. Therefore, the stacked notched saggers can exchange the mixed powder with the outside air during sintering through the side wall notch, that is, provide the oxygen required for sintering and discharge the two waste gases, water vapor and carbon dioxide. Thus, by stacking, at least two notched saggers can be sintered at the same time and the sintering quality can be ensured, thereby improving the production efficiency of the sintering process.

[0005] The first filling section of the flat-mouthed sagger and the second filling section of the notched sagger are identical in shape and size. Before leveling, each sagger is sealed separately, and then multiple notched saggers are stacked at the bottom, with the flat-mouthed saggers stacked on top of the notched saggers. Therefore, the sealing device must seal both the flat-mouthed and notched saggers.

[0006] Traditional sagger sealing methods use sponge compression. Because the exposed notch of a flat-mouthed sagger is relatively flat, the sponge provides a good seal. However, there are the following problems when using sponge to seal a notched sagger:

[0007] Sponges are poorly adapted to notches with complex shapes, such as trapezoidal or arc-shaped notches. Therefore, when sealing side wall notches, a large gap will be generated between the sponge and the inner circumferential wall of the side wall notch, resulting in poor sealing effect of the notch sagger, leading to more powder leakage, causing a large waste of powder and serious pollution of the workshop production environment.

[0008] Similarly, there is a lack of effective sealing methods for the crucibles during the transport from the leveling section to the sintering section. For example, Chinese patent CN208963883U proposes a sealing structure for a lithium battery sintering powder conveyor belt, which includes a support, a crucible mounted on the support, a seal at the bottom of the crucible, and a sealing cover on the outside of the crucible. The sealing cover is mounted on the support and includes a rear plate and two side plates fixed to the support, as well as multiple flip-top plates arranged along the conveying direction of the crucible. The rear plate, side plates, and multiple flip-top plates seal the crucible. The flip-top plates are hinged to the support and driven by a gas spring hinged to the support. Although the sealing cover is designed to open upwards, utilizing the space above the crucible and avoiding blockage of the passage when the cover is opened, this design is reasonable. While the sealing structure of the lithium battery sintering powder conveyor belt can seal the powder inside the crucible within the structure, preventing leakage during transport, a significant gap exists between the sealing cover and the crucible. During transport, some powder may fall between the sealing cover and the crucible, contaminating the outer wall of the crucible. This means the powder is more likely to leak out during transport. Furthermore, when the sealing structure separates from the crucible, the powder adhering to the outer wall of the crucible is more likely to leak out. Therefore, the sealing effect of the internal sealing structure on the crucible is relatively poor. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sealing device for sintering mixed powders that has a better sealing effect and is suitable for both flat-mouthed and notched saggers, as well as an integrated vibratory leveling and conveying device.

[0010] The objective of this invention is achieved through the following technical solution:

[0014] The telescopic sealing mechanism is provided in multiple ways, and each of the multiple telescopic sealing mechanisms is slidably disposed in one of the multiple mounting slots. Each of the telescopic sealing mechanisms is connected to the main bracket.

[0015] An elastic sealing sleeve is located in the receiving groove and connected to the main support. An annular action position is formed at the periphery of the end of the elastic sealing sleeve. A plurality of telescopic sealing mechanisms are arranged corresponding to the annular action position. The plurality of telescopic sealing mechanisms are used to act together on the annular action position so that the annular action position is attached to the periphery of the opening of the sagger.

[0016] Compared with the prior art, the present invention has at least the following advantages: the sealing device of the sagger for sintering mixed powder of the present invention has an elastic sealing sleeve with good elasticity, that is, the elastic sealing sleeve has good deformation capability and can be adapted to different openings, that is, it can be used for both flat-mouth saggers and notched saggers; multiple telescopic sealing mechanisms are arranged correspondingly to the annular action position, so that the annular action position is reliably attached to the periphery of the opening of the sagger, thereby ensuring the sealing effect of the sealing device of the sagger for sintering mixed powder on the sagger.

[0041] Please refer to the following: Figure 1 , Figure 3 and Figure 5 This application provides a sealing device 20 for a sagger used in sintering mixed powders. The sealing device 20 for the sintering mixed powders includes a base 50, a main support 60, a telescopic sealing mechanism 70, and an elastic sealing sleeve 80. The main support 60 is connected to the base 50 and has a receiving groove 101 and a plurality of mounting grooves 102. The receiving groove 101 is connected to the plurality of mounting grooves 102, and the plurality of mounting grooves 102 are arranged along the circumference of the main support 60. There are a plurality of telescopic sealing mechanisms 70, which are slidably disposed in the plurality of mounting grooves 102, and each telescopic sealing mechanism is connected to the main support 60. The elastic sealing sleeve 80 is located in the receiving groove 101 and connected to the main support 60. An annular action position 200 is formed at the periphery of the end of the elastic sealing sleeve 80. Multiple telescopic sealing mechanisms 70 are arranged corresponding to the annular action position 200. The multiple telescopic sealing mechanisms 70 are used to act together on the annular action position 200 so that the annular action position 200 is attached to the periphery of the opening 301 of the sagger 30.

[0042] Please refer to the following: Figure 3 , Figure 5 , Figures 8-14 as well as Figures 17-18In one embodiment, when the sagger 30 at a predetermined position needs to be sealed, the plurality of telescopic sealing mechanisms 70 first operate in the forward direction, that is, the plurality of telescopic sealing mechanisms 70 act together on the annular actuating position 200. Each telescopic sealing mechanism 70 slides within a corresponding mounting groove 102, that is, the actuating end of each telescopic sealing mechanism 70 moves toward the annular actuating position 200, and each telescopic sealing mechanism 70 presses against the predetermined position of the annular actuating position 200, thereby deforming the annular actuating position 200 and attaching it to the periphery of the opening 301 of the sagger 30 to seal the sagger 30. Conversely, when the sagger 30 does not need to be sealed, the plurality of telescopic sealing mechanisms 70 operate in the reverse direction. Each telescopic sealing mechanism 70 slides within a corresponding mounting groove 102, that is, the actuating end of each telescopic sealing mechanism 70 moves away from the annular actuating position 200, and each telescopic sealing mechanism 70 moves away from the annular actuating position 200, ultimately separating the elastic sealing sleeve 80 from the sagger 30.

[0043] The sealing device 20 for the sagger used in the sintering of mixed powder described above has an elastic sealing sleeve 80 with good elasticity, that is, the elastic sealing sleeve 80 has good deformation capability and can be adapted to different openings 301, that is, it can be used for both flat-mouth saggers 31 and notched saggers 32; multiple telescopic sealing mechanisms 70 are correspondingly arranged with the annular action position 200, so that the annular action position 200 is reliably attached to the periphery of the opening 301 of the sagger 30, thereby ensuring the sealing effect of the sealing device 20 for the sagger 30 of the sagger used in the sintering of mixed powder on the sagger 30.

[0044] Please refer to the following: Figures 8-11 , Figures 13-14 as well as Figures 17-18 It can be understood that the telescopic sealing mechanism 70 has the ability to telescopically deform, and can always act on the annular action position 200 through telescopic deformation when the elastic sealing sleeve 80 deforms, thereby reliably attaching the annular action position 200 to the periphery of the opening 301 of the sagger 30, thereby ensuring the sealing effect of the sealing device 20 of the sagger for sintering mixed powder on the sagger 30.

[0045] Please see Figure 3 It can be understood that the main support 60 is connected to the base 50, which ensures the connection stability between the base 50 and the main support 60. The base 50 plays a positioning role for the main support 60, thereby ensuring the sealing effect of the sealing device 20 of the sagger for sintering mixed powder.

[0046] Please refer to the following: Figure 3 and Figure 5In one embodiment, each telescopic sealing mechanism 70 includes a plurality of telescopic sealing assemblies 100 arranged side by side. It can be understood that the combined action of the plurality of telescopic sealing assemblies 100 on the annular action position 200 ensures the sealing effect of the sealing device 20 of the sagger for sintering the mixed powder on the opening 301 of the sagger 30.

[0047] Please refer to the following: Figure 3 and Figure 9 In one embodiment, multiple mounting slots 102 are arranged circumferentially along the outer peripheral wall of the main support 60. It can be understood that multiple telescopic sealing mechanisms 70 are slidably disposed one-to-one within the multiple mounting slots 102, i.e., the multiple telescopic sealing mechanisms 70 are arranged circumferentially along the outer peripheral wall of the main support 60. The multiple telescopic sealing mechanisms 70 are used to act together on the annular actuating position 200, so that the annular actuating position 200 is attached to the periphery of the opening 301 of the crucible 30.

[0048] Please refer to the following: Figure 3 and Figure 9 In one embodiment, a plurality of mounting slots 102 are circumferentially spaced along the outer peripheral wall of the main support 60. It is understood that a plurality of notches in the notched crucible 32 are circumferentially spaced along the outer peripheral wall of the crucible 30. To accommodate the notched crucible 32 with a plurality of notches spaced apart, the plurality of mounting slots 102 are further circumferentially spaced along the outer peripheral wall of the main support 60.

[0049] Please see Figure 6 In one embodiment, each telescopic sealing assembly 100 includes a holding frame 110, an elastic telescopic sliding assembly 120, and a pressure applying assembly 130. The holding frame 110 is fixedly connected to the main support 60. The elastic telescopic sliding assembly 120 of each telescopic sealing assembly 100 is located in a corresponding mounting groove 102. The elastic telescopic sliding assembly 120 is slidably connected to the holding frame 110 and the main support 60, respectively. The pressure applying assembly 130 is connected to the elastic telescopic sliding assembly 120 and is used to act on the annular action position 200. It can be understood that the holding frame 110 limits the elastic telescopic sliding assembly 120, thereby causing the elastic telescopic sliding assembly 120 to generate elastic force on the annular action position 200 through the pressure applying assembly 130, that is, to apply pressure to the annular action position 200, thereby making the annular action position 200 reliably attached to the periphery of the opening 301 of the crucible 30.

[0050] Please refer to the following: Figures 8-11 , Figures 13-14 as well as Figures 17-18In one embodiment, each telescopic sealing assembly 100 includes an elastic telescopic sliding assembly 120 comprising an elastic element 121 and a sliding guide frame 122. A pressure holding frame 110 has a sliding hole 201, and the sliding guide frame 122 passes through the sliding hole 201 and is slidably connected to the pressure holding frame 110. The elastic element 121 is sleeved on the sliding guide frame 122, and both ends of the elastic element 121 elastically abut against the sliding guide frame 122 and the pressure holding frame 110, respectively. A pressure applying assembly 130 is connected to the sliding guide frame 122. It can be understood that the pressure holding frame 110 guides the sliding guide frame 122 through the sliding hole 201, and the elastic element 121, sleeved on the sliding guide frame 122, guides the elastic element 121, thereby causing the elastic element 121 to expand and contract towards the annular action position 200, thus ensuring the sealing effect of the sealing device 20 of the sintering crucible for the mixed powder on the crucible 30. In this embodiment, the elastic element 121 is an elastic rubber or a coil spring.

[0051] Please refer to the following: Figures 8-11 , Figures 13-14 as well as Figures 17-18 In one embodiment, the sliding guide frame 122 of the elastic telescopic sliding component 120 of each telescopic sealing assembly 100 includes a guide post 123 and a slider 124 connected together. The guide post 123 passes through the sliding hole 201 and is slidably connected to the pressure holder 110. The elastic element 121 is sleeved on the guide post 123, and both ends of the elastic element 121 elastically abut against the slider 124 and the pressure holder 110, respectively. It can be understood that the pressure holder 110 guides the guide post 123 through the sliding hole 201, and the elastic element 121 is sleeved on the guide post 123, that is, the guide post 123 guides the elastic element 121, thereby causing the elastic element 121 to expand and contract toward the annular action position 200, thereby ensuring the sealing effect of the sealing device 20 of the sintering crucible for the mixed powder on the crucible 30.

[0052] Please refer to the following: Figures 5-7 In one embodiment, the slider 124 has a protruding sliding rib 125, and the main support 60 has a guide groove 62. The sliding rib 125 is slidably connected to the inner peripheral wall of the guide groove 62. It can be understood that the sliding rib 125 slides along the inner peripheral wall of the guide groove 62, that is, the guide groove 62 guides the sliding rib 125, thereby causing the pressure application component 130 to face the annular action position 200, thereby ensuring the sealing effect of the sealing device 20 of the sintering crucible for the mixed powder on the crucible 30.

[0053] Please refer to the following: Figures 8-12In one embodiment, the pressure-applying component 130 of each telescopic sealing assembly 100 includes a rotating bracket 131 and a holding portion 132 rotatably connected to each other. The rotating bracket 131 of each telescopic sealing assembly 100 is connected to a corresponding elastic telescopic sliding component 120, and the holding portion 132 acts on the annular actuating position 200. It can be understood that the holding portion 132 is rotatably connected to the rotating bracket 131, meaning the holding portion 132 can face different directions, thereby allowing multiple holding portions 132 to adapt to more complex notches. For example, the middle holding portion 132 does not rotate, while the holding portions 132 on both sides rotate in opposite directions, ensuring the sealing effect of the sealing device 20 for the sintering crucible of the mixed powder on the notched crucible 32 with a trapezoidal notch. In this embodiment, the pressure-applying component 130 of each telescopic sealing assembly 100 is a holding structure.

[0054] Please refer to the following: Figures 8-9 It should be noted that, in one embodiment, the periphery of the opening 301 of the flat-mouth sagger 31 moves toward the annular action position 200 until it is correspondingly positioned with and abuts against the annular action position 200. Then, the periphery of the opening 301 of the flat-mouth sagger 31 generates a pushing force on the annular action position 200 until the annular action position 200 abuts against the holding part 132 and the main support 60. At this time, the elastic telescopic sliding component 120 contracts and generates an elastic force on the annular action position 200, thereby making the annular action position 200 reliably attached to the periphery of the opening 301 of the flat-mouth sagger 31.

[0055] Please refer to the following: Figures 9-12 It should be noted that, in one embodiment, the periphery of the opening 301 of the notched sagger 32 moves toward the annular actuating position 200 until it corresponds to and abuts against the annular actuating position 200. Then, the periphery of the opening 301 of the notched sagger 32 exerts a pushing force on the annular actuating position 200 until the annular actuating position 200 abuts against the holding part 132 and the main support 60. When the inner peripheral wall of the side wall notch 302 of the notched sagger 32 is inclined to the holding part 132, one end of the holding part 132 is subjected to the side wall notch of the notched sagger 32. The pushing force of the inner peripheral wall of 302 causes rotation until the holding part 132 is attached to the inner peripheral wall of the side wall notch 302 of the notched sagger 32. Similarly, when the inner peripheral wall of the side wall notch 302 of the notched sagger 32 is parallel or coincident with the surface of the holding part 132, the holding part 132 does not rotate and is attached to the inner peripheral wall of the side wall notch 302 of the notched sagger 32. At this time, the elastic telescopic sliding component 120 contracts and generates elastic force on the annular action position 200, thereby making the annular action position 200 reliably attached to the periphery of the opening 301 of the notched sagger 32.

[0056] Please refer to the following: Figures 8-9 Furthermore, if the holding part 132 is connected to an adjacent holding part 132, it may easily obstruct the adjacent holding part 132, preventing it from rotating. This results in a problem of not being able to adapt to the corresponding shape. Therefore, a gap is formed between two adjacent holding parts 132. However, the gap will reduce the sealing effect of the sealing device 20 of the sagger for sintering mixed powder on the sagger 30. In order to simultaneously ensure the adaptability of the sealing device 20 of the sagger for sintering mixed powder to the sagger 30 and to ensure the sealing effect on the sagger 30, a flexible glass bead is further provided at one end of the holding part 132 near the adjacent holding part 132. It is understandable that the elastic glass beads will not scratch the elastic sealing sleeve 80, ensuring the service life of the sealing device 20 of the sagger for sintering mixed powder. Since the end of the elastic glass beads is spherical, it ensures that the adjacent holding parts 132 can rotate more easily, thereby ensuring the compatibility of the sealing device 20 of the sagger for sintering mixed powder with the sagger 30. Moreover, the elastic glass beads have the ability to stretch and deform, filling the gap between two adjacent holding parts 132. Even if the gap increases after the two holding parts 132 tilt and rotate, the elastic glass beads can fill the gap well, thereby ensuring the sealing effect of the sealing device 20 of the sagger for sintering mixed powder with the sagger 30. That is, the setting of the elastic glass beads can simultaneously ensure the compatibility of the sealing device 20 of the sagger for sintering mixed powder with the sagger 30 and ensure the sealing effect of the sagger 30.

[0057] Please see Figure 8 Furthermore, in one embodiment, the pressing part 132 is a sealing strip.

[0058] Please refer to the following: Figure 5 , Figures 8-11 , Figures 13-14 as well as Figures 17-18 In one embodiment, the main support 60 has a plurality of supporting feet protruding from it. These supporting feet movably abut against the annular actuating position 200. The supporting feet and a plurality of telescopic sealing mechanisms 70 work together to act on the annular actuating position 200, causing the annular actuating position 200 to adhere to the periphery of the opening 301 of the crucible 30. Each mounting groove 102 is formed between two adjacent supporting feet. It can be understood that the plurality of supporting feet and the plurality of telescopic sealing mechanisms 70 work together to act on the annular actuating position 200, causing the annular actuating position 200 to adhere to the periphery of the opening 301 of the crucible 30, and the supporting feet provide support for the elastic sealing sleeve 80, thus enabling the elastic sealing sleeve 80 to be formed.

[0059] It is understood that in other embodiments, the pressure-applying component 130 of each telescopic sealing assembly 100 is not limited to the pressure-holding structure that acts directly on the annular actuating position. Please refer to [further details omitted]. Figures 13-16In one embodiment, the pressure application component 130 of each telescopic sealing assembly 100 includes a pressing track 133, a fixing frame 134, and a pressing roller 135. The mounting groove group 102 includes a first fixing groove 103, a mounting groove 104, and a second fixing groove. The first fixing groove 103 and the second fixing groove are both connected to the mounting groove 104. The two ends of the pressing track 133 are respectively connected to the first fixing groove 103 and the second fixing groove. The elastic telescopic sliding component 120 of each telescopic sealing assembly 100 is located in the mounting groove 104 of the corresponding mounting groove group 102. The fixing frame 134 is connected to the elastic telescopic sliding component 120. The pressing roller 135 is rotatably connected to the fixing frame 134. The pressing roller 135 abuts against one side of the pressing track 133, and the other side of the pressing track 133 abuts against the annular action position 200. It is understood that when the sagger 30 moves toward the annular actuating position 200, the sagger 30 exerts a compressive force on the elastic element 121 through the annular actuating position 200, causing the elastic element 121 to contract and generate elastic force. This, in turn, causes the pressing roller 135 to exert pressure on the pressing track 133, resulting in greater tension on the pressing track 133. Consequently, the pressing track 133 reliably adheres the annular actuating position 200 to the periphery of the opening 301 of the sagger 30, thereby ensuring the sealing effect of the sealing device 20 of the sagger for sintering the mixed powder. In this embodiment, the pressure-applying component 130 of each telescopic sealing assembly 100 is a track structure.

[0060] Please refer to the following: Figures 13-16 It should be noted that, in one embodiment, the periphery of the opening 301 of the flat-mouthed sagger 31 moves toward the annular action position 200 until it is positioned corresponding to and abuts against the annular action position 200. Then, the periphery of the opening 301 of the flat-mouthed sagger 31 generates a pushing force on the annular action position 200 until the annular action position 200 abuts against the pressing track 133 and the main support 60. At this time, the elastic telescopic sliding component 120 contracts, giving the pressing track 133 a large tension, which in turn causes the pressing track 133 to generate an elastic force on the annular action position 200. The main support 60 also provides pressure on the annular action position 200, thereby making the annular action position 200 reliably attached to the periphery of the opening 301 of the flat-mouthed sagger 31.

[0061] Please refer to the following: Figures 13-16It should be noted that, in one embodiment, the periphery of the opening 301 of the notched sagger 32 moves toward the annular action position 200 until it corresponds to and abuts against the annular action position 200. Then, the periphery of the opening 301 of the notched sagger 32 generates a pushing force on the annular action position 200 until the annular action position 200 abuts against the pressing track 133 and the main support 60. At this time, the elastic telescopic sliding component 120 contracts, so that the pressing track 133 has a large tension and is adapted to the side wall notch 302 of the notched sagger 32. This causes the pressing track 133 to generate an elastic force on the annular action position 200, and the main support 60 also provides pressure on the annular action position 200, thereby making the annular action position 200 reliably attached to the periphery of the opening 301 of the notched sagger 32.

[0062] Please refer to the following: Figures 13-16 Furthermore, in one embodiment, the pressure-applying component 130 of each telescopic sealing assembly 100 further includes a first sliding rod 136 and a second sliding rod (not shown). The first sliding rod 136 is disposed in the first fixing groove 103, and the pressing track 133 is disposed between the inner peripheral wall of the first fixing groove 103 and the first sliding rod 136, with the first sliding rod 136 slidably connected to the pressing track 133. The second sliding rod is disposed in the second fixing groove, and the pressing track 133 is disposed between the inner peripheral wall of the second fixing groove and the second sliding rod, with the second sliding rod slidably connected to the pressing track 133. It can be understood that the first sliding rod 136 and the second sliding rod increase the tension of the pressing track 133, thereby ensuring the sealing effect of the sealing device 20 of the sintering crucible for mixed powder on the crucible 30.

[0063] Please see Figure 16 In one embodiment, the two ends of the compression track 133 are respectively provided with a first elastic part 138 and a second elastic part (not shown in the figure). The first elastic part 138 is elastically connected to the first fixing groove 103, and the second elastic part is elastically connected to the second fixing groove.

[0064] It is understood that in other embodiments, the pressure application component 130 of each telescopic sealing assembly 100 is not limited to a track structure. Please refer to [further details omitted]. Figures 17-18In one embodiment, the pressure application component 130 of each telescopic sealing assembly 100 includes a connecting frame 140, a magnetic element 141, and a flexible magnetic strip 142. The connecting frame 140 is connected to the elastic telescopic sliding assembly 120. The magnetic element 141 is disposed on the connecting frame 140. The magnetic element 141 and the flexible magnetic strip 142 are correspondingly disposed. The magnetism of the magnetic element 141 is the same as that of the flexible magnetic strip 142. The flexible magnetic strip 142 is disposed at the annular action position 200. It is understood that the magnetism of the magnetic component 141 is the same as that of the flexible magnetic strip 142. The magnetic component 141 generates a repulsive force on the flexible magnetic strip 142, causing the flexible magnetic strip 142 to adhere the annular action position 200 to the periphery of the opening 301 of the sagger 30 under the action of the repulsive force. Since the flexible magnetic strip 142 has good flexibility, it has good adaptability to both the flat-mouth sagger 31 and the notched sagger 32 with different notches. This ensures the sealing effect of the sealing device 20 of the sagger for sintering mixed powder and its wide adaptability to the sagger 30.

[0065] Please see Figure 5 In one embodiment, the resilient sealing sleeve 80 is formed with a deformation opening 801, which is opened away from the annular action position 200. It can be understood that the deformation opening 801 can increase the deformation space of the resilient sealing sleeve 80 and ensure the service life of the resilient sealing sleeve 80.

[0066] In one embodiment, the elastic sealing sleeve 80 is a silicone sealing sleeve. It is understood that the annular abutment 200 of the silicone sealing sleeve is used to adhere to the periphery of the opening 301 of the crucible 30. The silicone sealing sleeve has good elasticity, ensuring good compatibility between the silicone sealing sleeve and the flat-mouth crucible 31 and the notched crucible 32 with different notches. This ensures that the sealing device for the lithium battery mixed powder crucible 30 has broad compatibility with the crucible 30, and the elasticity reduces damage to the crucible 30 during the leveling process. Furthermore, the silicone sealing sleeve has good elongation and tear strength, ensuring its service life during the sealing process of the crucible 30. During the leveling process, the mixed powder easily comes into contact with the silicone sealing sleeve. The inner circumferential wall of the sleeve, due to the good corrosion resistance, chemical stability and aging resistance of the silicone sealing sleeve, effectively reduces the impact on the service life of the sealing device 20 of the sintering crucible for mixed powder; and the small pores on the surface of the silicone sealing sleeve reduce the loss of mixed powder adsorbed into the silicone sealing sleeve during the leveling process, and make it easy to clean the mixed powder adhering to the surface, thereby improving the reusability of the silicone sealing sleeve. This effectively alleviates the problem of low reusability caused by the traditional use of sponge for sealing, which results in the sponge adsorbing a lot of mixed powder and is difficult to clean completely; and the cost of the silicone sealing sleeve is also low.

[0067] Please see Figure 3It is understandable that the silicone sealing sleeve has good resilience. After the notched crucible 32 is leveled, the rebound force causes the rotating pressing part 132 to reset, ensuring the ease of use of the lithium battery mixed powder crucible 30 sealing device in the next round of sealing the crucible 30.

[0068] Please refer to the following: Figure 3 and Figure 6 In one embodiment, the main support 60 is a plastic main support 60, a metal main support 60, a wooden main support 60, or a stone main support 60. It is understood that the plastic main support 60 has high hardness, ensuring its positioning function on the pressure holder 110. This, in turn, allows the pressure holder 110 to position one end of the elastic element 121, which in turn generates elastic force on the annular actuating position 200. This ensures the annular actuating position 200 reliably adheres to the periphery of the notch in the sagger 30, thereby ensuring the sealing effect of the sealing device 20 for the sagger of the mixed powder sintering. Similarly, the metal main support 60 has high hardness, ensuring its positioning function on the pressure holder 110. This, in turn, allows the pressure holder 110 to position one end of the elastic element 121, which in turn generates elastic force on the annular actuating position 200. This, in turn, ensures the annular actuating position 200 reliably adheres to the periphery of the notch in the sagger 30, thereby ensuring the sealing effect of the sealing device 20 for the sagger of the mixed powder sintering. Similarly, the main wooden support 60 has high hardness, ensuring its positioning of the pressure frame 110, which in turn positions one end of the elastic element 121, causing the elastic element 121 to exert elastic force on the annular action position 200. This ensures that the annular action position 200 is reliably attached to the periphery of the notch in the sagger 30, thus ensuring the sealing effect of the sealing device 20 for the sagger 30. Likewise, the main stone support 60 has high hardness, ensuring its positioning of the pressure frame 110, which in turn positions one end of the elastic element 121, causing the elastic element 121 to exert elastic force on the annular action position 200. This ensures that the annular action position 200 is reliably attached to the periphery of the notch in the sagger 30, thus ensuring the sealing effect of the sealing device 20 for the sagger 30.

[0069] Please refer to the following: Figure 3 and Figure 4In one embodiment, the elastic sealing sleeve 80 forms a leveling cavity 802, which communicates with the opening 301 of the crucible 30. Furthermore, the larger the leveling cavity 802 of the elastic sealing sleeve 80, the more mixed powder adheres to the inner peripheral wall of the leveling cavity 802 after leveling, resulting in greater waste of mixed powder. To reduce the waste of mixed powder, the leveling cavity 802 needs to be reduced in size. In one embodiment, the base 50 includes a connecting column 510 and a protective cover 520. The connecting column 510, the main support 60, the telescopic sealing mechanism 70, and the elastic sealing sleeve 80 are all disposed within the protective cover 520. The connecting column 510 is connected to both the protective cover 520 and the main support 60. An extension gap 501 is formed between the protective cover 520 and the end of the main support 60 facing away from the crucible 30, and the pressure holder 110 is disposed within the extension gap 501.

[0070] Please refer to the following: Figure 19 and Figure 20 This application also provides an integrated vibratory leveling and conveying device 10. The aforementioned integrated vibratory leveling and conveying device 10 includes a lifting mechanism 40 and a sealing device 20 for the sintering sagger of the mixed powder as described in any of the above embodiments. The lifting mechanism 40 is disposed below the annular action position 200. The lifting mechanism 40 is used to carry and drive the sagger 30 to move up and down, so that the opening 301 of the sagger 30 is attached to the annular action position 200 during vibratory leveling or transportation.

[0071] The aforementioned integrated vibratory leveling and conveying equipment 10 is used to place the sagger 30 and adjust its position so that the opening 301 of the sagger 30 corresponds to the annular action position 200, thereby ensuring the sealing effect of the sealing device 20 of the sagger for sintering mixed powder on the sagger 30.

[0072] Please refer to the following: Figure 1 , Figure 2 , Figure 19 and Figure 20 In one embodiment, the lifting mechanism 40 includes a tray and a drive member, the power output end of which is connected to the tray, which supports the flat-mouthed sagger or notched sagger 32. In one embodiment, the drive member is a cylinder or an electric cylinder.

[0073] Please refer to the following: Figures 1-3 In one embodiment, the tray is provided with guide wheels, which are used to align the crucible 30 with the elastic sealing sleeve 80.

[0074] Compared with the prior art, the present invention has at least the following advantages:

[0075] The sealing device 20 of the sagger for sintering mixed powder of the present invention has an elastic sealing sleeve 80 with good elasticity, that is, the elastic sealing sleeve 80 has good deformation ability and can be adapted to different openings 301, that is, it can be used for both flat-mouth saggers 31 and notched saggers 32; multiple telescopic sealing mechanisms 70 are correspondingly arranged with annular action positions 200, so that the annular action positions 200 are reliably attached to the periphery of the opening 301 of the sagger 30, thereby ensuring the sealing effect of the sealing device 20 of the sagger for sintering mixed powder on the sagger 30.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
