Detailed Description

Referring to fig. 1 to 4, the present invention is a single head filling machine including: a filling head 1 for filling, a conveyor belt 2 for conveying the material bottles, and a bottle clamping device for clamping the material bottles in the filling process. Which in this embodiment is a bottle gripping belt mechanism 3.

The bottle belt clamping mechanism 3 comprises two sets of belt assemblies 30 arranged side by side, each set of belt assemblies consisting of two pulleys 31 and a belt 32 looped around the two pulleys 31. The belt 32 is preferably a rubber belt and is supported by a support member 37. The distance between the inner sides of the two rubber belts 32 can be adjusted according to the size of the material bottle to be filled, and the distance is slightly smaller than the outer diameter of the material bottle to be filled, so that the material bottle to be filled is clamped.

A clamping adjustment mechanism 33 for adjusting the distance between the belts 32, as shown in fig. 4, comprises a threaded rod 331 connected to one belt assembly 30, a first nut 332, and a second nut 333, wherein the threaded rod 331 comprises a first section 331a for screwing the first nut 332 and a second section 331b for screwing the second nut 333, wherein the screwing direction of the first section 331a and the first nut 332 is opposite to that of the second section 331b and the second nut 333. 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 the present embodiment, two clamping adjustment mechanisms 33 are provided, respectively, at both ends of the belt 32.

The bottle clamping belt mechanism 3 further comprises a lifting adjusting mechanism 34 for adjusting the height of the belt 32. In the present embodiment, two lift adjusting mechanisms 34 are provided, respectively, at both ends of the belt 32. The height of the belt 32 is adjusted according to the height 1/6-1/3 of the bottles to be filled.

The bottle belt clamping mechanism 3 further comprises two sets of swing arms 35, the swing arms 35 being connected to support members 37 for adjusting the angle of inclination of the belt 32, respectively. When treating that the filling bottle is toper or irregular shape, the belt of slope can be better with the bottle laminating, lets the accurate positioning of bottleneck in the first position of filling.

According to the present embodiment, the driving mechanism of the pulley 31 is a servomotor 36. The servo motor 36 drives the belt 32 to clamp the bottle 4 to be filled and move the bottle forwards. The bottle 4 to be filled is conveyed forward while being detected by a detection photo-electric (not shown). When the material bottle 4 to be filled runs to a designated position, the bottle mouth is accurately positioned, the servo motor 36 stops the belt 32 from rotating, and the filling head descends to start the filling process. After filling, the filling head rises and leaves the bottle mouth, (if the bottle is lacked in the middle, the corresponding filling head and the filling drive can not act, the function of no-bottle and no-filling is realized), the servo motor 36 drives the belt 32 to resume rotating, the filled material bottle is conveyed out of the filling machine, and the whole filling body enters the next movement period.

The high-speed start and the location are realized by adopting the servo motor in the embodiment, the filling speed can be greatly improved, and the filling speed is improved by at least one time compared with the existing structure.

In another embodiment, the drive mechanism may employ a common motor in conjunction with an encoder to achieve the same effect.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
