Detailed ways

Referring to Figures 1 to 4, the present invention is a single-head filling machine, comprising: a filling head 1 for filling, a conveyor belt 2 for conveying bottles, and clamping the bottles during the filling process bottle clamping device. The bottle clamping device is the bottle clamping belt mechanism 3 in this embodiment.

The bottle holding belt mechanism 3 includes two sets of belt assemblies 30 arranged side by side, each set of belt assemblies is composed of two pulleys 31 and a belt 32 surrounding the two pulleys 31 . The belt 32 is preferably a rubber belt and is supported by the support member 37 . The distance between the inner sides of the two rubber belts 32 can be adjusted according to the size of the bottle to be filled, and the distance should be slightly smaller than the outer diameter of the bottle to be filled, so as to hold the bottle to be filled.

The clamping adjustment mechanism 33 for adjusting the spacing between the belts 32, as shown in FIG. 4, includes a screw rod 331, a first nut 332, and a second nut 333 connected to a belt assembly 30, wherein the screw rod 331 includes a The first section 331a to which the first nut 332 is screwed and the second section 331b for the second nut 333 to be screwed together, wherein the screw directions of the first section 331a and the first nut 332 are the same as The helical directions of the second section 331b and the second nut 333 are opposite. When the screw 331 is rotated, the first nut 332 and the second nut 333 approach or move away from each other, so that the distance between the belts 32 is adjusted. In this embodiment, there are two clamping adjustment mechanisms 33 , which are respectively provided at both ends of the belt 32 .

The bottle-holding belt mechanism 3 also includes a lifting and lowering mechanism 34 for adjusting the height of the belt 32 . In this embodiment, there are two up-and-down adjustment mechanisms 34 , which are respectively provided at both ends of the belt 32 . The height of the belt 32 is adjusted according to 1/6-1/3 of the height of the bottle to be filled.

The bottle-holding belt mechanism 3 further includes two sets of swing arms 35 , which are connected to the support member 37 for adjusting the inclination angle of the belt 32 respectively. When the bottle body to be filled is conical or irregular, the inclined belt can better fit the bottle body, so that the bottle mouth can be accurately positioned at the filling head position.

According to the present embodiment, the drive mechanism of the pulley 31 is the servo motor 36 . The servo motor 36 drives the belt 32 to hold the bottle 4 to be filled and drives it to move forward. When the filling bottle 4 is conveyed forward, it is detected by the detection photoelectric (not shown). When the bottle 4 to be filled runs to the designated position, the bottle mouth is accurately positioned, the servo motor 36 stops the rotation of the belt 32, and the filling head descends to start the filling process. After the filling is completed, the filling head rises and leaves the bottle mouth. (If there is a shortage of bottles in the middle, the corresponding filling head and filling drive will not move, and the function of no filling without a bottle is realized), the servo motor 36 drives the belt 32 to resume rotation, and the The filled bottle is transported out of the filling machine, and the whole filling enters the next movement cycle.

In this embodiment, a servo motor is used to realize high-speed start-up and positioning, which can greatly improve the filling speed, which is at least doubled compared to the existing structure.

In another embodiment, the drive mechanism can use a common motor combined with an encoder to achieve the same effect.

The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present invention without creative efforts. Therefore, any technical solutions that can be obtained by those skilled in the art through logical analysis, reasoning or limited experiments on the basis of the prior art according to the concept of the present invention shall fall within the protection scope determined by the claims.
