The bottle clamping device 6 can accurately position the bottle to the filling station by cooperating with the star wheel 4 and the bottle holder 2, the bottle clamping device 6 can clamp the bottle by expanding the air bag 69, the rubber protrusions 611 increase the friction with the surface of the bottle, so that the bottle remains stable during the filling process, improves the accuracy of filling and product quality, and prevents the bottle opening from being worn.
[0028] Please refer to Figure 1In an embodiment, the star wheel 4 is installed inside the filling machine 3, the bottle holder 2 for assisting in fixing the bottle is installed on one side of the filling machine 3, the conveying belt 1 is arranged on one side of the filling machine 3, and the bottle holder 2 for assisting in fixing the bottle is arranged on the top of the conveying belt 1.
[0029] It should be noted that the conveying belt 1 conveys the bottles to be filled to the vicinity of the filling machine 3, the bottle holder 2 on the top of the conveying belt 1 assists in fixing the bottle, the star wheel 4 inside the filling machine 3 rotates to accurately position the bottle to the filling station, the electric telescopic rod 5 is installed on the top of the inside of the filling machine 3, and when the bottle reaches the specified position, the electric telescopic rod 5 is activated to extend downward to drive the bottle holder 6 connected at the bottom to descend.
[0030] Please refer to Figures 3-6 In an embodiment, one end of the sliding block 65 is triangularly shaped, the outer side of the sliding block 65 is slidably connected to the inner side of the guide metal shell 63, the elastic metal strip 66 is arc-shaped, the elastic metal strip 66 is arranged on the top of the empty chamber 64, the outer side of the piston 67 is slidably connected to the inner side of the empty chamber 64, the outer side of the piston 67 is tightly attached to the inner wall of the empty chamber 64, the top of the extrusion block 62 is tightly attached to the inclined surface of the sliding block 65, the outer side of the connecting rod 61 is slidably connected to the outer side of the guide metal shell 63, the vertical cross section of the extrusion block 62 is trapezoidal, the bottom outer side of the extrusion block 62 is tightly attached to the inner side of the guide metal shell 63, the gas bag 69 is connected to the empty chamber 64 through the fixing ring 610 and the connecting pipe 68, the gas bag 69 is spherical, and the gas bag 69, the fixing ring 610, and the connecting pipe 68 are in one-to-one correspondence.
[0031] It should be noted that since the vertical cross section of the extrusion block 62 is trapezoidal and the bottom outer side is tightly attached to the inner side of the guide metal shell 63, in the downward process, the extrusion block 62 can accurately guide the bottle holder 6 to the position of the bottle mouth of the bottle, ensuring the accuracy of the subsequent bottle clamping action. When the bottle mouth enters the position of the gas bag 69 inside the guide metal shell 63, due to the large weight of the guide metal shell 63, when the extrusion block 62 is lifted by the electric telescopic rod 5, the guide metal shell 63 is still at the bottle mouth of the bottle, and the extrusion block 62 will have a short upward trend relative to the guide metal shell 63. At this time, the top of the extrusion block 62 is tightly attached to the inclined surface of the sliding block 65, and the upward movement of the extrusion block 62 promotes the sliding block 65 to slide horizontally along the inner side of the guide metal shell 63. With the sliding of the sliding block 65, the elastic metal strip 66 fixedly connected at one end of the sliding block 65 is extruded, and at the same time, the sliding block 65 drives the piston 67 to move in the empty chamber 64. The movement of the piston 67 causes the gas in the empty chamber 64 to be quickly extruded into the gas bag 69 through the connecting pipe 68. The gas bag 69 is connected to the empty chamber 64 through the fixing ring 610 and the connecting pipe 68, and the gas bag 69 is spherical.

It is to be noted that the friction with the bottle surface is further increased, the bottle is ensured not to shake and slip in the filling process due to internal liquid flow, external mechanical vibration and other factors, the filling accuracy and product quality are ensured, and the wear of the bottle opening is prevented.
[0033] Please refer to Figure 3 In an embodiment, the empty warehouse 64 is provided in L shape, is distributed in a circular array inside the guide metal shell 63, and the inner side of the connecting pipe 68 is communicated with the inner side of the empty warehouse 64. It is to be noted that after filling is completed, the electric telescopic rod 5 is moved downward, the bottle clamping device 6 is lowered, the extrusion block 62 is moved downward again when the bottle falls, the extrusion block 62 is separated from the extrusion of the sliding block 65, the sliding block 65 is reset under the elastic force of the elastic metal strip 66, the gas in the air bag 69 is returned to the empty warehouse 64 through the connecting pipe 68, the bottle clamping device 6 returns to the initial state, and the next bottle clamping operation is prepared.
