The rotating assembly 20 rotates relative to the bottom wall 11, a first sealing channel 51 is arranged between the rotating assembly 20 and the bottom wall 11 at intervals and is communicated with the accommodating space 14, the air supply assembly 30 is arranged on one side of the bottom wall 11 away from the accommodating space 14 and is communicated with an air inlet of the first sealing channel 51, air is supplied to the accommodating space 14 of the coating tank 10 through the first sealing channel 51, so that air pressure in the first sealing channel 51 is larger than air pressure in the accommodating space 14, and further the material to be stirred is difficult to enter into the first sealing channel 51 to block rotation of the rotating assembly 20.

The respirator 81 is arranged on the coating tank 10, and the respirator 81 is communicated with the accommodating space 14 and is used for adjusting the air pressure in the accommodating space 14. Specifically, when the air supply assembly 30 is directed to the first sealing channel 51 to prevent the material to be stirred from entering the first sealing channel 51, the blown air of the air supply assembly 30 also enters the accommodating space 14 from the first sealing channel 51, so that the air pressure in the accommodating space 14 is increased. The respirator 81 may be used to remove air from the receiving space 14, so that the air pressure in the receiving space 14 may be reduced, and thus the air pressure in the coating tank 10 may be stabilized when the air supply assembly 30 is introduced into the receiving space 14.

In the wrapping device 1 provided by the application, the rotating assembly 20 rotates relative to the bottom wall 11 of the wrapping tank 10, a first sealing channel 51 is arranged between the rotating assembly 20 and the bottom wall 11 at intervals and is communicated with the accommodating space 14, and the air supply assembly 30 supplies air to the accommodating space 14 of the wrapping tank 10 through the first sealing channel 51, so that the air pressure in the first sealing channel 51 is greater than the air pressure in the accommodating space 14, and the material to be stirred is difficult to enter into the first sealing channel 51 to block the rotation of the rotating assembly 20. The respirator 81 communicates with the receiving space 14 for regulating the air pressure in the canister 10 when the air supply assembly 30 is directed into the receiving space 14.

In one embodiment, at least part of the first sealing channel 51 is the labyrinth channel, and the path of the labyrinth channel is longer and the number of times of bending back and forth is larger, so that the material to be stirred entering the labyrinth channel is difficult to pass through the labyrinth channel, and the sealing performance of the first sealing channel 51 is further improved.

The sealing assembly 40 is configured to provide the air intake through hole 42 communicating with the air supply assembly 30, so that the air intake through hole 42 can communicate with the second sealing passage 52 and intake air into the second sealing passage 52.

The sealing assembly 40 may be used to seal an end of the second sealing channel 52 facing away from the first sealing channel 51, so that the gas in the first sealing channel 51 and the second sealing channel 52 cannot overflow from an end of the second sealing channel 52 facing away from the first sealing channel 51, thereby ensuring that the gas blown by the gas supply assembly 30 can move from the second sealing channel 52 to the first sealing channel 51 and enter the accommodating space 14 through the first sealing channel 51, so as to avoid the material to be stirred from entering the first sealing channel 51.

In this embodiment, the gas supply assembly 30 includes a gas inlet conduit that communicates with the gas inlet through-hole 42 such that gas from the gas inlet conduit enters the gas inlet through-hole 42 and the second seal passage 52.

In the present embodiment, the number of the air intake through holes 42 is 2, and 2 air intake through holes 42 are disposed at two ends of the seal assembly 40 at opposite intervals, in other words, the connecting line direction of 2 air intake through holes 42 is the radial direction of the seal assembly 40. The sealing assembly 40 includes 2 air inlet through holes 42 connected to the second through hole, so as to further improve air inlet efficiency of the airtight passage in the wrapping device 1, and improve airtight effect of the wrapping device 1. The number of the air intake pipes is 2, and the number of the air intake through holes 42 is the same. In other embodiments, the number of the air intake pipes and the air intake through holes 42 may be 1, or 3, or 4, or more than 4, which is not limited in the present application.

Referring again to fig. 1, 2 and 3, fig. 3 is an enlarged schematic view of a portion of the cladding apparatus of fig. 2. In one embodiment, the seal assembly 40 includes an annular body 41 and at least one third seal 43, the third seal 43 is disposed between the annular body 41 and the rotating assembly 20, the third seal 43 is sealed at an end of the second seal channel 52 away from the first seal channel 51, and the third seal 43 is used for blocking gas in the second seal channel 52 from overflowing.

The third seal 43 is annular in shape, and the third seal 43 is disposed between the annular body 41 and the rotating assembly 20 and abuts against an inner wall of the annular body 41 and an outer peripheral side of the rotating assembly 20, respectively. In the axial direction of the rotating assembly 20, the third sealing member 43 is disposed on a side of the air inlet through hole 42 facing away from the bottom wall 11, and the third sealing member 43 is sealed at an end of the second sealing channel 52 facing away from the first sealing channel 51, so as to block the air in the second sealing channel 52 from overflowing from a direction facing away from the first sealing channel 51.

Further, the third sealing member 43 may also be used to block the material to be stirred, preventing the material to be stirred from entering the area below the third sealing member 43.

Optionally, the material of the third sealing member 43 includes, but is not limited to, silicone, plastic or other materials with good sealing performance.

In one embodiment, the side of the third seal 43 facing the second seal channel 52 is provided with an inclined surface that is remote from the annular body 41 in a direction approaching the bottom wall 11. The third sealing member 43 is provided with the inclined surface, so that the pressure of the third sealing member 43 towards the second sealing channel 52 side to the rotating assembly 20 is increased, the gas in the second sealing channel 52 is prevented from overflowing from the third sealing member 43, and the tightness of the second sealing channel 52 is improved.

Referring to fig. 1 to 4, fig. 4 is a schematic structural diagram of a spacer assembly, a sealing assembly and a cooling assembly according to an embodiment of the application. In one embodiment, the annular body 41 further includes a powder outlet channel 44 in communication with the second sealing channel 52, the powder outlet channel 44 being configured to pass the material to be stirred within the second sealing channel 52.

The powder outlet channel 44 is used for discharging the material to be stirred entering the second sealing channel 52, so as to avoid the material to be stirred from blocking the second sealing channel 52 or affecting the rotation of the rotating assembly 20. Specifically, the air pressure in the powder outlet channel 44 is smaller, and the material to be stirred in the second sealing channel 52 moves toward the powder outlet channel 44 and is discharged through the powder outlet channel 44. For example, in one embodiment, the powder outlet channel 44 communicates with a storage device, and the air pressure in the storage device is lower than the air pressure in the second sealing channel 52, so that the material to be stirred enters the storage device through the powder outlet channel 44. In another embodiment, the powder outlet channel 44 is connected to a powder suction device, and the powder suction device is used for providing suction force, so that the material to be stirred in the second sealing channel 52 is sucked into the powder outlet channel 44 and the powder suction device, which is not limited in the application. When the material to be stirred is not contained in the containing space 14, the powder sucking device works to suck out the material to be stirred in the airtight passage.

Referring to fig. 1, 2 and 3, in an embodiment, the sealing assembly 40 further includes a fourth sealing member 54, the fourth sealing member 54 surrounds the outer peripheral side of the rotating assembly 20, the fourth sealing member 54 is disposed between the annular body 41 and the rotating assembly 20, the fourth sealing member 54 is used for blocking the material to be stirred, and the fourth sealing member 54 has a hardness less than that of the third sealing member 43.

The fourth sealing member 54 is disposed in the second sealing channel 52, the fourth sealing member 54 surrounds the outer peripheral side of the rotating assembly 20, and one end of the fourth sealing member 54 is fixedly connected with the annular body 41. When the air supply assembly 30 is in air supply, the end of the fourth sealing member 54, which is close to the rotating assembly 20, is stressed to form a certain gap with the rotating assembly 20 for air flow to pass through, and the gap is smaller, so that the fourth sealing member 54 has a certain sealing powder blocking effect to further block the material to be stirred. When the air supply assembly 30 does not perform air intake, one end of the fourth sealing member 54 abuts against the annular body 41, the other end abuts against the rotating assembly 20, and the fourth sealing member 54 can be used for blocking the material to be stirred from passing through.

The fourth sealing member 54 has a hardness smaller than that of the third sealing member 43, and the fourth sealing member 54 is a sealing member having a certain flexibility. Optionally, the material of the fourth sealing member 54 includes, but is not limited to, flexible materials such as flexible silica gel, flexible plastic, and the like. Optionally, the fourth seal 54 has a pressure resistance less than the pressure resistance of the third seal 43.

In one embodiment, the side of the fourth seal 54 facing the air intake through hole 42 is provided with an inclined surface that is away from the annular body 41 in a direction approaching the bottom wall 11. The inclined surface of the fourth seal 54 is advantageous in reducing resistance to gas rushing through the fourth seal 54.

Referring to fig. 1, 2 and 3 again, in one embodiment, the rotating assembly 20 further includes a fifth sealing member 55, the fifth sealing member 55 includes a main body 551 and an extension portion 552 connected to each other, the main body 551 extends along a first direction, the extension portion 552 extends along a direction close to the bottom wall 11 and is spaced from the rotating assembly 20, the first direction is a radial direction of the rotating assembly 20, and the fifth sealing member 55 is used for blocking the material to be stirred.

The annular body 41 further includes a receiving groove, the main body 551 is disposed in the receiving groove, and a gap between the main body 551 and a groove wall of the receiving groove forms a part of the second sealing channel 52.

In the axial direction of the rotating assembly 20, the fifth seal 55 is located between the air intake through hole 42 and the first seal passage 51, and the fifth seal 55 is located on a side of the fourth seal 54 facing away from the third seal 43.

The main body 551 extends along a first direction, the extension portion 552 extends along a direction close to the bottom wall 11 and is spaced from the rotating assembly 20, that is, the main body 551, the extension portion 552, and the rotating assembly 20 form a receiving groove, where the receiving groove may be used to receive the material to be stirred, so as to block the material to be stirred from moving in the second sealing channel 52.

The annular body 41 further includes the receiving recess, and the extension 552 is disposed in the receiving recess. The gap paths formed between the main body 551, the extension 552 and the accommodating groove are longer and the number of times of bending back and forth is larger, so that the material to be stirred entering the gap is difficult to pass through the gap, and the sealing performance of the second sealing channel 52 is further improved.

Referring to fig. 1, 2 and 5, fig. 5 is a partially enlarged schematic cross-sectional view of the cladding apparatus of fig. 2. In one embodiment, the cladding device 1 further includes a spacer member 60 disposed between the bottom wall 11 and the seal member 40, the spacer member 60 being disposed on the outer peripheral side of the rotation member 20, and a third seal passage 53 communicating the first seal passage 51 and the second seal passage 52 being formed between the spacer member 60 and the rotation member 20.

The cladding device 1 further comprises a first sealing member 82, wherein the first sealing member 82 is sandwiched between the bottom wall 11 and the spacing component 60, and the first sealing member 82 is used for blocking the gas in the third sealing channel 53 from overflowing from the gap between the bottom wall 11 and the spacing component 60.

In this embodiment, the first sealing member 82 is configured to prevent the gas in the third sealing channel 53 formed by the spacer assembly 60 and the rotating assembly 20 from leaking from the gap between the bottom wall 11 and the spacer assembly 60, so as to ensure that the gas in the third sealing channel 53 is not leaked, and can flow into the accommodating space 14 of the coating tank 10, so that the finer part of the material to be stirred is prevented from falling from the gap between the bottom wall 11 and the spacer assembly 60, so that the coating device 1 can be used normally, and the service life of the coating device 1 is prolonged. Also, the first sealing member 82 may serve to prevent external air from entering the third sealing passage 53 from the gap between the bottom wall 11 and the spacing member 60, thereby securing an oxygen-proof environment within the can 10.

It should be noted that, in one embodiment, the material to be stirred needs to be coated in a relatively high-temperature environment to improve the coating efficiency. The cladding device 1 further comprises a heating component 91, wherein the heating component 91 is arranged on one side of the peripheral side wall 13 away from the accommodating space 14, and the heating component 91 is used for heating the peripheral side wall 13 so as to increase the temperature in the accommodating space 14.

In this embodiment, the spacer assembly 60 may be an insulating assembly for insulating the heat of the coating tank 10, and preventing the sealing assembly 40 from being damaged due to an excessively high temperature.

In other embodiments, the spacer assembly 60 may be a connecting assembly for connecting the sealing assembly 40 and the coating tank 10 when the material to be stirred does not need to be coated in a relatively high temperature environment, which is not limited by the present application.

The present application is illustrated with the spacer assembly 60 as an insulating assembly and should not be construed as limiting the application.

Referring to fig. 1, fig. 2 and fig. 6, fig. 6 is a schematic structural diagram of a spacer according to an embodiment of the application. In one embodiment, the spacer assembly 60 is a heat insulation assembly, a heat dissipation cavity 61, a first liquid inlet pipe 62 and a first liquid outlet pipe 63 are formed around the peripheral side wall of the spacer assembly 60, the first liquid inlet pipe 62 and the first liquid outlet pipe 63 are communicated with the heat dissipation cavity 61, the heat dissipation cavity 61 is annularly arranged at the outer peripheral side of the rotating assembly 20, the first liquid inlet pipe 62 is used for conducting cooling medium to the heat dissipation cavity 61, the heat dissipation cavity 61 is used for accommodating the cooling medium, the cooling medium is used for cooling the rotating assembly 20, and the first liquid outlet pipe 63 is used for guiding out the cooling medium in the heat dissipation cavity 61.

The spacer assembly 60 is disposed around the outer peripheral side of the rotating assembly 20, and a heat dissipation cavity 61 is formed around the peripheral side wall of the spacer assembly 60. The heat dissipation chamber 61 is disposed adjacent to the rotating assembly 20. The first liquid inlet pipe 62 and the first liquid outlet pipe 63 are both used for conducting the cooling medium. The cooling medium flows from the first liquid inlet pipe 62 to the heat dissipation chamber 61. The cooling medium in the heat dissipation chamber 61 absorbs heat transferred from the coating tank 10 to the rotating assembly 20, and cools the rotating assembly 20. The cooling medium warmed up in the heat dissipation chamber 61 flows out of the heat dissipation chamber 61 through the first liquid outlet pipe 63 to carry heat away from the spacer assembly 60. Alternatively, the cooling medium in the present embodiment may be a liquid or a gas. The cooling medium may be water, oil, etc.

In this embodiment, the cooling medium is introduced into the heat dissipation cavity 61 of the spacer assembly 60 to absorb at least part of the heat transferred from the coating tank 10 to the rotating assembly 20, so as to cool the rotating assembly 20, thereby reducing the heat transferred from the coating tank 10 to the sealing assembly 40 through the rotating assembly 20, further reducing the temperature of the sealing assembly 40, reducing the damage probability of the sealing assembly 40 caused by the high-temperature coating tank 10, and prolonging the service life of the sealing assembly 40.

It should be noted that the spacer assembly 60 with a lower temperature does not directly absorb the heat of the rotating assembly 20, but the spacer assembly 60 may absorb the heat radiated from the rotating assembly 20, so that the rotating assembly 20 maintains a lower temperature.

In one embodiment, the spacer assembly 60 further includes at least one heat exchanging member 64, the at least one heat exchanging member 64 being disposed on a wall of the heat dissipating chamber 61 adjacent to the rotating assembly 20, the heat exchanging member 64 being configured to contact the cooling medium.

Alternatively, the heat exchanging member 64 may be installed on the inner cavity wall of the heat dissipation chamber 61, and the heat exchanging member 64 may be spaced apart from the outer cavity wall of the heat dissipation chamber 61. Optionally, the number of the heat exchanging elements 64 is plural, and plural heat exchanging elements 64 are disposed at intervals along the axial direction of the rotating assembly 20. Further alternatively, the spacing of any adjacent two heat exchange members 64 is equal.

In this embodiment, the heat exchange member 64 increases the contact area between the wall of the heat dissipation cavity 61 and the cooling medium, so that the cooling medium can take away more heat from the wall of the heat dissipation cavity 61, and further the cooling medium can take away more heat from the rotating assembly 20, thereby improving the heat dissipation effect of the spacer assembly 60.
