Each limiting groove is arranged along the circumferential direction, each limiting area 50 is further provided with a first limiting hole 503 and a second limiting hole 504, and the first limiting hole 503 and the second limiting hole 504 of each limiting area 50 are located right above two ends of the second limiting groove 502 in the limiting area 50. The hole wall of the inner hole of the star wheel body 1 outside each limit area 50 is provided with a steel ball 9 which can be elastically jacked into each limit groove or jacked into the first limit hole and the second limit hole. In this embodiment, the mounting structure of the steel ball 9 includes: the side wall of the star wheel body 1 is provided with an installation through hole 12, a compression spring 13 is arranged in the installation through hole 12, a plug 14 is arranged in the installation through hole 12 at the outer end of the compression spring 13, the steel ball 9 is arranged at the inner end of the compression spring 13, and the steel ball 9 protrudes out of the installation through hole 12 under the action of the compression spring 13 but does not fall out of the installation through hole 12.

The up-and-down movement of the positioning disc 5 can drive each limiting groove to be blocked by the corresponding steel ball 9, when the limiting groove at a certain height position is blocked by the corresponding steel ball 9, all the driving shafts 61 just extend into the clamping block clamping grooves corresponding to the limiting grooves at the height position, in this state, the positioning disc 5 rotates back and forth, when one end or the other end of the limiting groove is blocked by the steel ball 9, the clamping block clamping grooves on the clamping blocks, which all the driving shafts 61 extend, are just in a clamping state or are all in a non-clamping state, at the moment, the positioning disc 5 continues to move downwards so that the limiting holes at the end block the steel balls 9, and all the driving shafts 61 just extend into the corresponding locking holes.

As will be described in detail below, the set of slots at each star slot 11 is locked in the initial state. Initial state, the first clamp splice draw-in groove 31 of every star wheel draw-in groove 11 department, second clamp splice draw-in groove 41 all is in the joint state, every second spacing hole 504 is blocked by corresponding steel ball 9, every drive shaft 61 is all through corresponding second drive groove 42, first drive groove 32 stretches into to corresponding first locking hole 101 in, thereby lock the first clamp splice draw-in groove 31 and the second clamp splice draw-in groove 41 of every star wheel draw-in groove 11 department at the joint state, second clamp splice draw-in groove 41 of every star wheel draw-in groove department 11 is outwards salient most under this state, container 2 can block into in every second clamp splice draw-in groove 41, promptly: in this state, each second block engaging groove 41 performs the operation of engaging the container 2, as shown in fig. 5.

In an initial state, the positioning disc 6 moves vertically upwards, each second limiting hole 504 is separated from the corresponding steel ball 9, when the first limiting groove 501 of each limiting area 5 is blocked by the corresponding steel ball 9, each driving shaft 61 only extends into the corresponding second driving groove 42, at the moment, the positioning disc 6 rotates until one end of each first limiting groove 501, which is positioned in the first limiting hole 503, is blocked by the steel ball 9, in the process, the driving shaft 61 drives the second clamping block clamping groove 41 on the second clamping block 4 to rotate around the corresponding hinge shaft 7 in the direction far away from the edge of the star wheel body 1 until the second clamping block clamping groove 41 is in a non-clamping state, at the moment, the positioning disc 4 moves vertically upwards, so that each first limiting hole 503 is blocked by the corresponding steel ball 9, in the process, the driving shaft 61 just extends into the second positioning hole locking hole 102 through the second driving groove 42 and the clamping block 301 of the first clamping block 3, thereby lock the first clamp splice draw-in groove 31 of every star gear draw-in groove 11 department at joint state, second clamp splice draw-in groove 41 and lock in non-joint state, first clamp splice draw-in groove 31 outwards protrusion in star gear draw-in groove 11 under this state, therefore container 2 can block into to every first clamp splice draw-in groove 31 under this state, promptly: in this state, each first block engaging groove 31 performs the operation of engaging the container, as shown in fig. 6.

In an initial state, the positioning disc 6 vertically moves upwards, each second limiting hole 504 is separated from the corresponding steel ball 9, when the second limiting groove 502 of each limiting area 5 is blocked by the corresponding steel ball 9, each driving shaft 61 extends into the first driving groove 32 through the second driving groove 42, at the moment, the positioning disc 6 rotates until one end of each second limiting groove 502, which is located in the first limiting hole 503, is blocked by the steel ball 9, in the process, the driving shaft 61 drives the second clamping block clamping groove 41 on the second clamping block 4 and the first clamping block clamping groove 31 on the first clamping block 3 to synchronously rotate around the corresponding hinge shaft 7 in the direction far away from the edge of the star wheel body 1 until the second clamping block clamping groove 41 and the first clamping block clamping groove 31 are both located in a non-clamping state, then, the positioning disc 4 vertically moves upwards, so that each first limiting hole 503 is blocked by the corresponding steel ball 9, and in the process, the driving shaft 61 just passes through the second driving groove 42, the second clamping groove 41, the first clamping block clamping, First drive slot 32 stretches into in second locking hole 102 to all lock the first clamp splice draw-in groove 31 and the second clamp splice draw-in groove 41 of every star gear draw-in groove 11 department at non-joint state, do not have on this form star gear draw-in groove 11 to shelter from, container 2 can block into to the star gear draw-in groove 11 under this state, promptly: in this state the star wheel pockets 11 engage the containers, as shown in fig. 7.

In this embodiment, the driving disk 6 is fixedly connected with the positioning disk 5 through a plurality of supporting shafts 8, a gap is left between the positioning disk 5 and the driving disk 6, when the driving shaft 61 extends downward from the top into a driving groove of a certain clamping block, the top surface of the positioning disk 5 is lower than the bottom surface of the clamping block layer, but is higher than the top surfaces of all clamping blocks which are not extended, so that the clamping blocks which are extended by the driving shaft 61 are not prevented from rotating in the direction away from the outer edge of the star wheel body 1, but the clamping blocks which are not extended by the driving shaft 61 can be prevented from rotating in the direction away from the outer edge of the star wheel body 1, and the follow-up rotation of the clamping blocks can be effectively prevented, as.

In this embodiment, the driving disc 6 is provided with two handles 62 at intervals for facilitating the driving disc 6 to rotate and move up and down, so as to facilitate the operation and control of the working personnel. Adopt the manual work to go up and down and rotate through handle control driving-disc 6, simple structure, the cost of manufacture is low, and handle 62 cooperation stop gear can be very convenient carry out the switching of draw-in groove.

The star wheel is generally divided into a bottle mouth star wheel used for clamping a container mouth part and a bottle body star wheel used for clamping a container body, the attached figures 1-9 are only described by taking clamping on the container body part as examples, and in the actual use process, the star wheel used for conveying containers can also be used for clamping and conveying the bottle mouth part.

The invention has the advantages that: the star wheel clamping grooves and the clamping block clamping grooves at 11 positions of each star wheel clamping groove are respectively connected with a container, and the star wheel clamping grooves at 11 positions of each star wheel clamping groove and the clamping block clamping grooves can be respectively connected with the containers. Secondly, simple structure, it is convenient to switch to can effectively improve filling production efficiency, can reduce filling manufacturing cost again simultaneously.
