[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0031] In order to illustrate the technical solution of the present invention, a detailed description is given below in conjunction with specific drawings and embodiments.

[0032] See also Figures 1 to 4 The embodiment of the present invention provides a multi-gas-path pipeline 11, including a first pipeline 111 and a second pipeline 112, wherein the first pipeline 111 is sleeved outside the second pipeline 112, and there is a gap between the first pipeline 111 and the second pipeline 112, and one end of the first pipeline 111 is provided with a first air hole 1111 and a second air hole 1112 in sequence from outside to inside along its axial direction, and the other end of the first pipeline 111 is provided with a fourth air hole 1114 and a third air hole 1113 in sequence from outside to inside along its axial direction, and the second pipeline 112 is sealed and connected to the first pipeline 111 at a position between the first air hole 1111 and the second air hole 1112 and a position between the fourth air hole 1114 and the third air hole 1113 respectively; the first air hole 1111, the second pipeline 112 and the fourth air hole 1114 are connected in sequence to form a first gas path, and the second air hole 1112, the gap and the third air hole 1113 are connected in sequence to form a second gas path.

[0033] The multi-gas-path pipeline 11 provided in the present embodiment adopts the first pipeline 111 and the second pipeline 112 which are nested inside and outside. The space in the second pipeline 112 is connected to the first air hole 1111 and the fourth air hole 1114 to form a first gas path. The space between the first pipeline 111 and the second pipeline 112 is connected to the second air hole 1112 and the third air hole 1113 to form a second gas path. In this way, when the devices connected at both ends of the multi-gas-path pipeline 11 need to rotate relative to each other, the first gas path and the second gas path will not be entangled or interfere with each other, and can work independently and stably and reliably.

[0034] In a specific scheme of the present embodiment, the first gas circuit and the second gas circuit are used to connect the vacuum generator and the suction nozzle 13, and are further used in a multi-gas circuit adsorption device. It should be understood that the multi-gas circuit pipeline 11 provided in the present embodiment can also be used for gas circuit connection of other equipment, and can also play a technical effect of preventing the first gas circuit and the second gas circuit from being entangled or interfering with each other when the equipment at both ends of the multi-gas circuit pipeline 11 needs to rotate relative to each other. For example, the multi-gas circuit pipeline 11 provided in the present embodiment can be used in a multi-gas circuit blowing device to connect the high-voltage generator and the blowing nozzle to prevent the entanglement and interference between the gas circuits from affecting the stable operation of the equipment. The description of the working mode of the multi-gas circuit pipeline 11 in a specific usage scenario in this specification should not be used as a limitation on its protection scope.

[0035] As an optional solution of this embodiment, the air hole can be an opening arranged at the end of the first pipe 111. Such an arrangement facilitates the direct connection of the vacuum generator or the suction nozzle 13 to the two ends of the multi-channel pipe 11. For example, the first air hole 1111, the second air hole 1112 and the fourth air hole 1114 are all arranged at the ends of the multi-channel pipe 11, and the third air hole 1113 is arranged on the side of the multi-channel pipe 11. At this time, the second air hole 1112 is annular, and the fourth air hole 1114 and the third air hole 1113 are simultaneously inserted into the connection structure corresponding to the vacuum generator. The first suction nozzle 131 is arranged at the end of the first pipe 111, and the propulsion and reset mechanism controls the multi-channel pipe 11 to move along its axial direction to control the movement of the first suction nozzle 131; the second suction nozzle 132 can be slidably connected to the side of the first pipe 111, and works independently under the control of the propulsion and reset mechanism. In this way, the vacuum generator can be arranged at one end of the multi-channel pipe 11 instead of the side, and other connecting devices or structures can be omitted, so that the equipment is simplified and easy to process and manufacture.

[0036] See also Figures 1 to 4 , considering that the end of the multi-channel pipe 11 generally needs to be connected to the rotating power mechanism, a more reasonable layout is given below. In one embodiment of the present invention, the first air hole 1111, the second air hole 1112, the third air hole 1113 and the fourth air hole 1114 are arranged on the side wall of the first pipe 111. Such an arrangement is convenient for directly connecting the vacuum generator or the suction nozzle 13 to the side of the multi-channel pipe 11. For the case where other necessary equipment is arranged at the end of the multi-channel pipe 11 and the vacuum generator needs to be arranged on the side of the multi-channel pipe 11, such an arrangement is convenient for setting the vacuum generator on the side of the multi-channel pipe 11, omitting other connecting devices or structures, simplifying the equipment, and facilitating processing and manufacturing; it is also convenient to set the propulsion and reset mechanisms respectively to independently control the first suction nozzle 131 and the second suction nozzle 132. There is no need to push and reset the entire multi-channel pipe 11, and the first suction nozzle 131 and the second suction nozzle 132 can work independently without entanglement and interference.

[0037] In one embodiment of the present invention, an air guide groove is provided along the circumference of the first pipe 1111 at a position on the outer wall of the first pipe 111 corresponding to at least one of the first air hole 1111, the second air hole 1112, the third air hole 1113 and the fourth air hole 1114. In this way, when other structures are nested outside the first pipe 111 and the structures are provided with air holes, it is not necessary to completely correspond the air holes of the first pipe 111 to the air holes of the nested structure to connect the air path. At the same time, when the first pipe 111 needs to rotate relative to the nested structure, the connection of the air path can be ensured, and the air path will not be blocked due to the air holes of the first pipe 111 not facing the air holes of the nested structure. As a specific solution of this embodiment, if the air holes provided on the side wall of the first pipe 111 need to communicate with the air hole structure of the external nested structure, an air guide groove 113 is provided on the outer wall of the side wall corresponding to the air hole along its circumference to simplify its installation connection and ensure the connection of the air path during relative rotation.

[0038] See also Figures 1 to 4 At least one end of the second pipe 112 is a fixed end 1121, which extends along the inner wall of the first pipe 111 in a direction away from each air hole of the first pipe 111, and the side wall of the fixed end 1121 of the second pipe 112 is provided with a conducting air hole 1122 for connecting with the first air path. The fixed end 1121 is used to relatively fix the second pipe 112 and the first pipe 111, to prevent the second pipe 112 and the first pipe 111 from being connected and slipping at the sealing part, causing the second pipe 112 to be misaligned, and to avoid blockage or interference between the first air path and the second air path.

[0039] See also Figures 1 to 4 In one embodiment of the present invention, an air guide groove 113 is provided along its circumference at a position corresponding to the air guide hole 1122 on the outer wall of the second pipe 112, which is used to communicate with the fourth air hole 1114 to ensure the connectivity of the second air path when the second pipe 112 and the first pipe 111 rotate relative to each other and facilitate the installation and connection of the first pipe 111 and the second pipe 112.

[0040] See also Figures 1 to 4As a specific solution of this embodiment, the multi-gas-path pipeline 11 also includes a rotating sealing seat 12, which is sleeved on the outer wall of the first pipeline 111 at a position corresponding to at least one of the air holes. The rotating sealing seat 12 can rotate relative to the first pipeline 111 around the axial direction of the multi-gas-path pipeline 11, and form a seal with the first pipeline 111. An air guide hole is provided on the rotating sealing seat 12, and an air guide groove 113 is provided outside the first air hole 1111 and the second air hole 1112, which is used to connect the first pipeline 111 to the vacuum generator arranged on the side of the multi-gas-path pipeline 11 through the rotating sealing seat 12; one end of the second pipeline 112 close to the fourth air hole 1114 is a fixed end 1121, and an air guide groove 113 is provided outside the air guide hole 1122, which is used to connect the air guide hole 1122 and the fourth air hole 1114.

[0041] The present invention further provides a labeling device, which adopts the above-mentioned multi-air pipeline 11 to solve the technical problem that the multiple air pipelines of the traditional multi-nozzle labeling device are easily entangled and interfered with each other.

[0042] See also Figures 6 to 8 Another object of the present invention is to provide a labeling device, a labeling device comprising a lifting mechanism, a rotating mechanism and an adsorption mechanism, the adsorption mechanism comprising a vacuum generator (not shown in the figure), a suction nozzle 13 and the multi-air-channel pipe 11 as described above, the lifting mechanism comprising a first propulsion structure 211, a second propulsion structure 212, a first clamping seat 221, a second clamping seat 222, a first reset structure 231 and a second reset structure 232, the multi-air-channel pipe 11 is respectively connected to the vacuum generator and the suction nozzle 13, the rotating mechanism is connected to the multi-air-channel pipe 11, the first propulsion structure 211 and the second propulsion structure 222 are arranged on one side of the multi-air-channel pipe 11, when the labeling device is working, the positions of the rotating mechanism, the first propulsion structure 221, the second propulsion structure 222 and the vacuum generator are fixed, and the rotating structure controls the rotation of the first clamping seat 221, the second clamping seat 222, the multi-air-channel pipe 11 and the suction nozzle 13.

[0043] The labeling device provided by the present invention adopts the first pipe 111 and the second pipe 112 nested inside and outside to form the first air path and the second air path. During rotation, the multiple air paths will not get tangled or interfere with each other. At the same time, its special lifting mechanism can ensure that when the multi-line pipes are rotated to any angle, the lifting and lowering actions of the multiple suction nozzles 13 can be controlled separately.

[0044] See also Figure 5 and Figure 8In one embodiment of the present invention, the first propulsion structure 211 and the second propulsion structure 212 are arranged side by side, and are respectively used to push the first card seat 221 and the second card seat 222; the first reset structure 231 and the second reset structure 232 are respectively connected to the first card seat 221 and the second card seat 222, and are respectively used to reset the first card seat 221 and the second card seat 222; the first card seat 221 and the second card seat 222 can rotate around the axial direction of the multi-gas pipeline 11, and the first propulsion structure 211 can push the first card seat 221 when the first card seat 221 and the second card seat 222 rotate around the axial direction of the multi-gas pipeline 11, and the second propulsion structure 212 can push the second card seat 222 when the first card seat 221 and the second card seat 222 rotate around the axial direction of the multi-gas pipeline 11.

[0045] See also Figure 5 and Figure 8 The first card seat 221 includes a first disk-shaped portion 2211 and a first sheet-shaped portion 2212 connected to the first disk-shaped portion 2211, and a first through hole 2213 is opened on the first disk-shaped portion 2211. The lifting mechanism also includes a fixed platform 24, and the positions of the fixed platform 24 and the first propulsion structure 211 and the second propulsion structure 212 are relatively fixed. The first propulsion structure 211 abuts against the first disk-shaped portion 2211, and the first reset structure 231 abuts against the fixed platform 24 and is connected to the first disk-shaped portion 2211; the second card seat 222 includes a second disk-shaped portion 2221 coaxial with the first disk-shaped portion 2211, and a second sheet-shaped portion 2222 passing through the first through hole 2213 and connected to the second disk-shaped portion 2221, the second propulsion structure 212 abuts against the second disk-shaped portion 2221, and the second reset structure 232 is connected to the second disk-shaped portion 2221 and passes through the first through hole 2213. In this way, when the first card seat 221 and the second card seat 222 are rotated to any angle, the first propulsion structure 211 can push the first card seat 221 and reset it by abutting against the first reset structure 231 of the fixed platform 24; the second propulsion structure 212 can push the second card seat 222 and reset it by connecting the fixed platform 24 and the second disc-shaped portion 2221 through the first through hole 2213.

[0046] As a specific solution of this embodiment, the first propulsion structure 211 and the second propulsion structure 212 use cylinders.

[0047] See also Figure 5 and Figure 8As a specific solution of this embodiment, the first reset structure 231 and the second reset structure 232 use spring needles, the first propulsion structure 211 is located between the first disc-shaped portion 2211 and the fixing platform 24 and is sleeved with a first spring (not shown in the figure), and the second reset structure 232 is located between the second disc-shaped portion 2221 and the first disc-shaped portion 2211 and is sleeved with a second spring (not shown in the figure); the second disc-shaped portion 2221 is provided with a second through hole 2223, the multi-path pipeline 11 passes through the second through hole 2223 and the first through hole 2213, and the first suction nozzle 131 is fixed to the first plate The end of the sheet-shaped portion 2212 away from the first disc-shaped portion 2211 is connected to the first air circuit through a hose, the second suction nozzle 132 is fixed to the end of the second sheet-shaped portion 2222 away from the second disc-shaped portion 2221, and is connected to the second air circuit through a hose, the first propulsion structure 211 and the second propulsion structure 212 are fixed and arranged on one side of the multi-air circuit pipeline 11, respectively abutting the first disc-shaped portion 2211 and the second disc-shaped portion 2221, the first holder 221 and the second holder 222 rotate with the rotation of the multi-air circuit pipeline 11, and can respectively control the lifting and lowering actions of the first suction nozzle 131 and the second suction nozzle 132. Preferably, the elastic coefficient of the first spring is greater than the elastic coefficient of the second spring needle, so as to prevent the first holder 221 from moving together with the elastic force of the first spring when the second propulsion structure 212 pushes the second holder 222.

[0048] See also Figures 6 to 8 In one embodiment of the present invention, one end of the first pipe 111 provided with the first air hole 1111 and the second air hole 1112 can be rotatably connected to the vacuum generator, and one end of the multi-line pipe 11 provided with the fourth air hole 1114 and the third air hole 1113 is fixedly connected to the suction nozzle 13. The rotating mechanism includes a rotating motor 31 and a coupling 32. The first pipe 111 is fixedly connected to the rotating motor 31 through the coupling 32, and the rotating motor 31 drives the first pipe 111 to rotate. The rotation of the label drives the rotation of the first card seat 221, the second card seat 222 and the suction nozzle 13, thereby realizing the control of the rotation of the suction nozzle 13.

[0049] See also Figures 6 to 8In one embodiment of the present invention, the outer wall of the first pipe 111 is provided with a threaded section and a nut 33 is provided on the outer wall. A position sensor 34 is provided at the nut 33. When the first pipe 111 rotates, the nut 33 does not rotate in the circumferential direction of the first pipe 111 and moves in the axial direction of the first pipe 111. The position sensor 34 detects the direction and angle of rotation of the first pipe 111 by detecting the position of the nut 33. When the multi-line pipe rotates, since the nut 33 does not rotate in the circumferential direction of the first pipe 111, the nut 33 moves in the axial direction of the multi-line pipe under the action of the thread. The position sensor can know the rotation direction and angle of the multi-line pipe by detecting the position of the nut 33. By feeding back the data of the rotation direction and angle of the multi-line pipe and controlling the rotating mechanism according to the data, the zero return of the multi-line pipe can be realized, and then the rotation zero return of the suction nozzle 13 can be realized.
