[0041] As Figures 1 - 5As shown in the figure, in this embodiment, the star wheel conveying device includes a base 1, a driving assembly, a baffle 3, a star wheel mounting plate 4, and a clamping assembly 5. Among them, the driving assembly includes a motor and a rotating shaft 2. The rotating shaft 2 is rotatably arranged on the base 1, and the output end of the motor is connected to the rotating shaft 2. The baffle 3 is installed on the base 1, and the star wheel mounting plate 4 is arranged on the rotating shaft 2. The clamping assembly 5 includes two clamping parts 51, an elastic member 52, and a cam 53. Both clamping parts 51 are rotatably arranged on the star wheel mounting plate 4. The cam 53 is arranged at the driving end of the clamping part 51. The cam 53 can contact the baffle 3 to open the clamping ends of the two clamping parts 51. The elastic member 52 is connected between the two clamping parts 51, and the elastic member 52 is always in a compressed state. The two clamping parts 51 can clamp the bottle 100 under the action of the elastic member 52. Specifically, the base 1 is fixed on the ground. The rotating shaft 2 is arranged inside the base 1. The two ends of the rotating shaft 2 are respectively connected to the motor and the star wheel mounting plate 4. The baffle 3 is fixedly installed on the outer periphery of the base 1, and the baffle 3 is located below the star wheel mounting plate 4. The two ends of the elastic member 52 are respectively connected to the two clamping parts 51. Both clamping parts 51 are rotationally matched with the star wheel mounting plate 4. The two ends of the clamping part 51 are respectively a clamping end and a driving end. The clamping ends of the two clamping parts 51 are closed or opened for clamping or loosening the bottle 100. The cam 53 is connected to the driving end of the clamping part 51. Preferably, a plurality of star wheel conveying devices are provided. The plurality of star wheel conveying devices are sequentially arranged between the bottle blowing machine and the filling machine in a straight line direction or a set direction, greatly prolonging the cooling time of the bottle 100, and capable of transporting more bottles 100 in the same time, with high working efficiency.

[0042] The working principle of this star wheel conveying device is as follows: After the preform is blown into the bottle 100 by the bottle blowing machine and formed, it enters from the bottle inlet side of the star wheel conveying device. At the same time, the base 1 always remains stationary, the baffle 3 remains stationary, and the rotating shaft 2 rotates in the base 1 under the driving action of the motor. The rotating shaft 2 drives the star wheel mounting plate 4 to rotate, and the two clamping parts 51 rotate synchronously with the star wheel mounting plate 4. When the cam 53 contacts the baffle 3, the clamping ends of the two clamping parts 51 open. At the same time, the elastic member 52 elongates, and the bottle mouth or bottleneck of the bottle 100 is sent into the clamping ends of the two clamping parts 51. When the cam 53 separates from the baffle 3, under the rebounding action of the elastic member 52, the clamping ends of the two clamping parts 51 close and clamp the bottle 100. The bottle 100 makes a circular motion synchronously with the star wheel mounting plate 4 until the bottle 100 is transported to the filling machine. This avoids the situation of the bottle 100 falling over, has a firm clamping, and the bottles 100 are arranged in an orderly manner during transportation and will not be squeezed to affect the appearance of the bottle 100. Compared with the traditional linear conveying, the conveying path of the star wheel conveying device is a curve, which is beneficial to prolong the cooling time of the bottle 100 in the same-sized space and reduce the area occupied by the equipment in the factory building.
