[0009] As a further improvement of the above technical solution, a sprocket is fixedly mounted on the sleeve.

[0010] As a further improvement of the above technical solution, a first fixing ring is provided on the top of the mobile platform, a first bearing is fixedly sleeved on the sleeve, and the bearing is installed in the first fixing ring.

[0011] As a further improvement of the above technical solution, second bearings are provided on both sides of the mobile platform.

[0012] As a further improvement of the above technical solution, a second fixing ring is provided at the bottom of the mobile platform, and a third bearing is fixedly sleeved on the second fixing ring.

[0013] As a further improvement of the above technical solution, a fixing groove is provided on the inner side of the first fixing ring and the outer side of the second fixing ring, and a retaining ring is provided in the fixing groove to limit and fix the first bearing and the third bearing.

[0014] The beneficial effects of the utility model are as follows: the magnetic attraction device and the magnetic attraction part are used to realize the rotation of the bottle, and the orientation of multiple bottles is unified during continuous production, thereby realizing the continuous production of irregular bottles.

[0025] Reference Figures 1 to 4 A plastic bottle rotation positioning structure includes: a mobile platform 1, a sleeve 2 is rotatably mounted on the mobile platform 1, a mounting shaft 4 is sleeved in the sleeve 2, a magnetic attraction part 5 is fixedly mounted on the mounting shaft 4, and a magnetic attraction device 6 is provided on one side of the mobile platform 1. When in use, a bottle blank 7 is arranged at the top of the mounting shaft 4, and when the formed bottle moves to the magnetic attraction device 6, the magnetic attraction device 6 is started, and the magnetic attraction device 6 attracts the magnetic attraction part 5, driving the mounting shaft 4 to rotate, so that the direction of the bottle can be positioned, so that it can be used to produce irregular bottles, and the structure is simple.

[0026] As a preferred embodiment, a sprocket 3 is fixedly mounted on the sleeve 2, and the sprocket 3 is connected to a chain of an external device. When the mobile platform 1 moves, the sprocket 3 rolls on the chain, so that the sleeve 2 and the mounting shaft 4 can rotate, and when the bottle blank 7 is heated by the heating device, uniform heating can be ensured. When leaving the heating zone, the rotational movement of the sleeve 2 stops in a random direction, and then the sleeve 2 is straightened by magnetic attraction so that the sleeve 2 is in the same direction.

[0027] As a preferred embodiment, a first fixing ring 11 is provided on the top of the mobile platform 1, a first bearing 21 is fixedly sleeved on the sleeve 2, and the first bearing 21 is installed in the first fixing ring 11. Therefore, the sleeve 2 can rotate smoothly relative to the mobile platform 1.

[0028] As a preferred embodiment, second bearings 12 are provided on both sides of the mobile platform 1, and the second bearings 12 are used to overlap on the track of the entire production line, so that the movement of the mobile platform is smoother.

[0029] As a preferred embodiment, a second fixing ring 13 is provided at the bottom of the mobile platform 1, and a third bearing 14 is fixedly sleeved on the second fixing ring 13. The third bearing 14 can be clamped on the production line track to limit the left and right deviation of the mobile platform 1.

[0030] As a preferred embodiment, a fixing groove 15 is provided on the inner side of the first fixing ring 11 and the outer side of the second fixing ring 13 . A snap ring 16 is provided in the fixing groove 15 . The snap ring 16 is used to limit and fix the first bearing 21 and the third bearing 14 .

[0031] This device is a part of the whole bottle production line. During the processing, the preform 7 needs to be rotated to be heated and then blow-molded. Since the processed bottles have an asymmetric structure, each bottle needs to be oriented in a unified direction, which is beneficial for other related operations such as labeling. When the bottles pass through this device, the direction can be unified.

[0032] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
