[0030] refer to Figures 1 to 3An embodiment of the present invention provides a dispensing device 1, including a shell 11 and a rotating part 12. The shell 11 is penetrated by a receiving hole 111, which receives the rotating part 12. The rotating part 12 can rotate relative to the shell 11. A fluid inlet 112 is provided on the side of the shell 11, and the fluid inlet 112 is connected to the receiving hole 111. The hole wall of the receiving hole 111 is provided with an annular recess with an accommodating cavity 113, which is provided at the connection between the fluid inlet 112 and the accommodating hole 111. A fluid channel 131, a gas channel 132 and a power supply channel 133 are penetrated by the rotating part 12, and the fluid channel 131 is connected to the accommodating cavity 113. The gas channel 132, the power supply channel 133 and the fluid channel 131 are spaced apart from each other.

[0031] The embodiment of the present invention comprises a housing 11 and a rotating portion 12 to form a dispensing device 1, wherein the housing 11 is provided with a receiving hole 111, which receives the rotating portion 12, and the rotating portion 12 is provided with a fluid channel 131, a gas channel 132 and a power supply channel 133. The rotating portion 12 can rotate relative to the housing 11, connecting the stationary parts of the filling machine 2 to the housing 11 and the rotating parts to the rotating portion 12. The fluid channel 131, the gas channel 132 and the power supply channel 133 are used to respectively accommodate wires, liquids and gases, thereby reducing the occupied volume.

[0032] Furthermore, a fluid inlet 112 is provided on the side of the housing 11. The fluid inlet 112 communicates with the receiving hole 111. The wall of the receiving hole 111 is provided with a receiving cavity 113, which is formed as an annular depression. The receiving cavity 113 is located at the junction of the fluid inlet 112 and the receiving hole 111. The fluid channel 131 communicates with the receiving cavity 113, so that when the rotating part 12 rotates relative to the housing 11, the fluid channel 131 can always maintain fluid communication with the fluid inlet 112. This avoids affecting the rotation of the rotating part while ensuring that the liquid at the fluid inlet 112 can be continuously input into the fluid channel 131 through the receiving cavity 113. In addition, the gas channel 132, the power supply channel 133, and the fluid channel 131 are spaced apart from each other, so that the power supply channel 133, the gas channel 132, and the fluid channel 131 can be integrated into a single device, thereby preventing interference between media such as wires, liquids, and gases.

[0033] Therefore, the distribution device 1 according to the embodiment of the present invention has a small size and rotates smoothly, and can reduce interference between wires and pipes.

[0034] In one embodiment, reference Figure 3The rotating portion 12 includes a first shaft 121 and a second shaft 122 that are fixedly connected. A gas channel 132 runs through the first and second shafts 121, 122, and a power channel 133 runs through the first shaft 121, ensuring the supply of gas and the electric eye during rotation. Furthermore, a conductive slip ring 14 is fixedly mounted on the sidewall of the second shaft 122. The conductive slip ring 14 includes a conductive ring 141 and a brush 142. Brush 142 remains electrically connected to conductive ring 141 as it rotates relative to the conductive ring 141. Brush 142 is fixedly connected to the sidewall of the second shaft 122 and is connected to a power cord. The power cord of power channel 133 is electrically connected to brush 142. That is, when the rotating portion 12 is driven to rotate, brush 142 always abuts against the rotating conductive ring 141, ensuring that the power cord on brush 142 remains electrically connected to the power cord in power channel 133. This also prevents the power cord from becoming tangled and affecting the rotation of the rotating portion 12.

[0035] In particular, refer to Figure 2 The end of the first shaft 121 away from the second shaft 122 protrudes from the accommodating hole 111 of the shell 11, and the gas outlet of the gas channel 132 and the power cord outlet of the power channel 133 are arranged on the side of the end of the first shaft 121 away from the second shaft 122, so that the fluid outlet, gas outlet and power cord outlet can be arranged at intervals.

[0036] Preferably, reference Figure 3 The distribution device 1 of the embodiment of the present invention further includes a protective cover 15 that wraps the second shaft 122 and the conductive slip ring 14. The protective cover 15 is fixedly connected to the housing 11. The protective cover 15 is provided to protect the second shaft 122 and the conductive slip ring 14 to prevent foreign objects from entering or dust from accumulating. The conductive ring 141 of the conductive slip ring 14 is fixedly connected to the protective cover 15, which also helps to stabilize the rotation of the conductive ring 141 on the second shaft 122.

[0037] Another preferred method is to refer to Figure 2 The end of the gas channel 132 is connected to a rotary joint 16, and the end of the rotary joint 16 away from the gas channel 132 is connected to the gas supply pipe. The rotary joint 16 is a closed rotary connector for 360° rotating conveying medium, which can input gas from the gas supply pipe into the rotating second shaft 122, ensuring air tightness while also ensuring high-speed rotation of the second shaft 122.

[0038] Another preferred embodiment is to refer to Figure 2The gas channel 132 between the first shaft 121 and the second shaft 122 is provided with a buffer chamber 123. This chamber not only adjusts the direction of the gas channel 132 but also provides a buffering effect on the gas flow, ensuring uniform gas flow from the outlet of the gas channel 132. Furthermore, the buffer chamber 123 is spaced apart from the power channel 133 to prevent interference between the gas channel 132 and the power channel 133.

[0039] Another preferred embodiment is to refer to Figure 2 A sealing ring 124 is provided at the connection between the first shaft 121 and the second shaft 122. By providing the sealing ring 124, the airtightness after the first shaft 121 and the second shaft 122 are connected can be improved.

[0040] In one embodiment, reference Figure 3 A fixing frame 114 is fixedly provided on the housing 11 , and the housing 11 can be assisted in being fixed by connecting a bracket to the fixing frame 114 .

[0041] Optionally, refer to Figure 2 A rotating seal ring 17 and a bearing 18 are provided between the rotating part 12 and the outer shell 11. The rotating seal ring 17 is a component that can rotate with the rotating part 12 and always maintain a sealed state between the rotating part 12 and the outer shell 11, while the bearing 18 can provide axial support force between the rotating part 12 and the outer shell 11, reduce the friction coefficient between the rotating part 12 and the outer shell 11, and ensure the rotation accuracy between the two, so that the rotating part 12 of the embodiment of the present invention can maintain sealing and smooth rotation when rotating relative to the outer shell 11, and has high rotation accuracy.

[0042] The rotating seal 17 can be a Glyd ring, which is composed of a rubber O-ring and a polytetrafluoroethylene ring. The O-ring is used to apply force. When acting on the piston seal, it has the characteristics of low friction, no creep, low starting force, and high pressure resistance. It can be divided into Glyd rings for holes and Glyd rings for shafts, but their sealing function is the same. Due to its inherent deformation, it generates a high initial contact stress on the sealing surface, preventing the leakage of unpressurized liquid. When the hydraulic cylinder is operating, the pressurized liquid, through the elastic deformation of the O-ring, begins to squeeze the polytetrafluoroethylene ring to the maximum extent, forcing it to adhere to the sealing surface, generating a high additional contact stress that increases with the pressure of the pressurized liquid. Together with the initial contact stress, it prevents the leakage of the pressurized liquid.

[0043] Preferably, the rotary seal ring 17 is provided between the bearing 18 and the fluid inlet 112 , and the rotary seal ring 17 is used to limit the fluid medium in the rotating part 12 from leaking into the bearing 18 .

[0044] Further, refer to Figure 2An observation hole 115 is provided through the side wall of the housing 11. The observation hole 115 is located on the side of the rotating seal ring 17 facing away from the fluid inlet 112. There are at least two rotating seal rings 17, one on each side of the fluid inlet 112, to seal both sides of the rotating portion 12. The leakage of the fluid medium can be observed through the observation hole 115. When the fluid medium leaks from the observation hole 115, it indicates that the rotating seal ring 17 is damaged and needs to be replaced in time.

[0045] refer to Figure 4 An embodiment of the present invention further provides a filling system comprising a filling machine 2 and a dispensing device 1 according to any of the aforementioned embodiments. The housing 11 of the dispensing device 1 is fixedly connected to the filling machine 2, the fluid conduit of the filling machine 2 is connected to the fluid inlet 112 of the dispensing device 1, the power cord of the filling machine 2 is connected to the power channel 133 of the dispensing device 1, and the gas supply pipe of the filling machine 2 is connected to the gas channel 132 of the dispensing device 1. The dispensing device 1 in this embodiment can have the same structure and achieve the same effects as the dispensing device 1 in the aforementioned embodiments, and will not be described in detail in this embodiment.
