[0043] Referring to Figures 1 to 3 A special-shaped bottle continuous filling mechanism, comprising a conveying chain 1, a tray 2 slidingly arranged on the conveying chain 1, and a filling device 3 for filling powder into a special-shaped bottle 8, the special-shaped bottle 8 being placed on the tray 2 and transported along the conveying chain 1, the conveying chain 1 comprising a first conveying section 11 and a second conveying section 12 arranged in sequence along the advancing direction of the special-shaped bottle 8, and the filling port of the filling device 3 being located above the second conveying section 12;

[0044] The tray 2 is provided with a bushing 21 on each of the two sides;

[0045] The first transfer cylinder 121 is arranged on one side of the second conveying section 12 and close to one end of the first conveying section 11. The output end of the first transfer cylinder 121 is connected to a first connecting rod 122, which is parallel to the second conveying section 12. A plurality of first inserting rod cylinders 123 are arranged on the first connecting rod 122. The output end of the first inserting rod cylinder 123 is provided with a first inserting rod 124 which can be inserted into the insertion hole 21. The axial direction of the first inserting rod 124 is perpendicular to the length direction of the first connecting rod 122. After the first inserting rod 124 is inserted into the insertion hole 21 of the tray 2, the first transfer cylinder 121 moves the first connecting rod 122 and the first inserting rod cylinder 123 to transfer the tray 2 from the first conveying section 11 to the second conveying section 12. When it is necessary to transfer the special-shaped bottle 8 from the first conveying section 11 to the second conveying section 12, the first connecting rod 122 is first driven by the first transfer cylinder 121 to move towards the first conveying section 11 until the first inserting rod 124 is aligned with the insertion hole 21 of the tray 2. Then the first inserting rod 124 is inserted into the insertion hole 21 of the tray 2 by driving the first inserting rod cylinder 123. Subsequently, the first connecting rod 122 is driven by the first transfer cylinder 121 to move towards the second conveying section 12. At this time, the first connecting rod 122 drives the first inserting rod cylinder 123, the first inserting rod 124, the tray 2 on the first conveying section 11 and the special-shaped bottle 8 on the tray 2 to move towards the second conveying section 12, thereby transferring the special-shaped bottle 8 to the second conveying section 12. Finally, the first inserting rod 124 is driven by the first inserting rod cylinder 123 to move away from the insertion hole 21 of the tray 2, waiting for the next transfer. In this embodiment, three first inserting rod cylinders 123 are arranged on the first connecting rod 122.

Of course, the number of first inserting rod cylinders 123 can be increased or decreased according to needs, which is not limited herein. Arranging the first transfer cylinder 121 on one side of the second conveying section 12 instead of one side of the first conveying section 11 can shorten the length of the first conveying section 11, thereby shortening the length of the conveying chain 1 and saving more space.

[0046] The second conveying section 12 is provided with a second moving cylinder 125 at one end close to the first conveying section 11 and opposite to one side of the first moving cylinder 121.

The second connecting rod 126 is provided with a plurality of second inserting rod cylinders 127. The output end of the second inserting rod cylinder 127 is provided with a second inserting rod 128 which can be inserted into the insertion hole 21. The axial direction of the second inserting rod 128 is perpendicular to the length direction of the second connecting rod 126. After the second inserting rod 128 is inserted into the insertion hole 21 of the tray 2, the second moving cylinder 125 moves the second connecting rod 126 and the second inserting rod cylinder 127 to move the tray 2 entering the second conveying section 12 one by one to below the filling port of the filling device 3. When filling is needed, the second inserting rod 128 is driven by the second inserting rod cylinder 127 to be inserted into the insertion hole 21 of the tray 2, and then the second connecting rod 126 is driven by the second moving cylinder 125 to move towards the filling port of the filling device 3. At this time, the second connecting rod 126 drives the second inserting rod cylinder 127, the second inserting rod 128, the tray 2 on the second conveying section 12 and the special-shaped bottle 8 on the tray 2 to move towards the filling port of the filling device 3, so as to move the special-shaped bottle 8 to below the filling port of the filling device 3. The powder is filled into the special-shaped bottle 8 by starting the filling device 3. Then the second inserting rod 128 is driven by the second inserting rod cylinder 127 to move away from the insertion hole 21 of the tray 2. Then the second connecting rod 126 is driven by the second inserting rod cylinder 127 to reset the second inserting rod cylinder 127 and the second inserting rod 128, so that the second connecting rod 126 returns to the initial position to wait for the next moving. The special-shaped bottle 8 can be moved one by one to below the filling port of the filling device 3 by controlling the moving distance of the second connecting rod 126. At the same time, the special-shaped bottle 8 which has completed filling can be moved out of below the filling port of the filling device 3 one by one. The moving distance of single movement is equal to the length of one tray 2. In addition, the tray 2 which has moved out of below the filling port of the filling device 3 is pushed by the rear tray 2 to move along the second conveying section 12 to the outlet end of the second conveying section 12. In this embodiment, the second connecting rod 126 is provided with three second inserting rod cylinders 127. The second moving cylinder 125 can move three special-shaped bottles 8 on the second conveying section 12 at the same time in single movement.

The output end of the third inserting rod cylinder 1211 is provided with a third inserting rod 1212 which can be inserted into the insertion hole 21. The axial direction of the third inserting rod 1212 is perpendicular to the length direction of the third connecting rod 1210. After the third inserting rod 1212 is inserted into the insertion hole 21 of the tray 2, the third transfer cylinder 129 moves the third connecting rod 1210 and the third inserting rod cylinder 1211 to transfer the tray 2 from the second conveying section 12 to the third conveying section 13. When it is needed to transfer the special-shaped bottle 8 from the second conveying section 12 to the third conveying section 13, the third inserting rod 1212 is first driven by the third inserting rod cylinder 1211 to be inserted into the insertion hole 21 of the tray 2, and then the third connecting rod 1210 is driven by the third transfer cylinder 129 to move towards the third conveying section 13. At this time, the third connecting rod 1210 drives the third inserting rod cylinder 1211, the third inserting rod 1212, the tray 2 on the third conveying section 13 and the special-shaped bottle 8 on the tray 2 to move towards the third conveying section 13, so as to transfer the special-shaped bottle 8 to the third conveying section 13. Subsequently, the third inserting rod 1212 is driven by the third inserting rod cylinder 1211 to be separated from the insertion hole 21 of the tray 2, and then the third connecting rod 1210 is driven by the third transfer cylinder 129 to drive the third inserting rod cylinder 1211 and the third inserting rod 1212 to reset. In this embodiment, three third inserting rod cylinders 1211 are arranged on the third connecting rod 1210. The three special-shaped bottles 8 on the second conveying section 12 can be simultaneously transferred to the third conveying section 13 by a single movement of the third inserting rod cylinder 1211. Of course, the number of the third inserting rod cylinder 1211 can be increased or decreased according to needs, which is not limited herein. The third transfer cylinder 129 is arranged on one side of the second conveying section 12 instead of being arranged on one side of the third conveying section 13, which can shorten the length of the third conveying section 13, thereby shortening the length of the conveying chain 1 and saving more space.
