Technical Field
[0001] The utility model relates to the technical field of packaging machinery, in particular to a bottle mouth up and down direction correction mechanism. Background Art
[0002] In the packaging of many products, packaging bottles are used, especially plastic packaging bottles, which are not only beautiful and varied in shape, but also light in weight and low in production cost. They have long been popular in all walks of life.
[0003] Bottle unscramblers are used to sort randomly stacked bottles and arrange them in order and direction on the conveyor belt, and transfer the bottles to other machines for the next process (such as filling, labeling, packing, etc.) at high speed and high efficiency to improve the production efficiency of the entire production line. However, when unscrambling bottles, traditional bottle unscramblers cannot correct the bottle mouth in the up and down direction, and the consistency of the bottle mouth direction on the conveyor line is very important. If the bottle mouth direction is inconsistent, it will have a great impact on the subsequent filling and packaging operations. Therefore, in the actual production process, it is necessary to manually organize the bottles so that the bottle mouth direction of the bottles is completely consistent, which results in a high labor intensity for the workers and a certain requirement for the conveying speed of the bottles, resulting in low production efficiency. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a bottle mouth up and down direction correction mechanism, which can automatically correct the bottle mouth of the packaging bottle in the up and down direction, so that the bottle mouth direction of the packaging bottle is completely consistent, which is conducive to improving work efficiency.

[0007] During operation, the packaging bottle to be corrected enters the bottle sorting groove from the front end opening of the bottle sorting groove, and then slides down to the position matched with the packaging bottle limiting plate, and the bottle mouth or bottle bottom is limited by the packaging bottle limiting plate; then, the bottle supporting movable plate swings downward around its side part under the drive of the swing mechanism, and the cooperation among the packaging bottle limiting plate, the bottle supporting movable plate and the bottle sorting bucket is utilized to make a packaging bottle on the bottle supporting movable plate automatically flip over to an upright state with the bottle mouth facing upward and the bottle bottom facing downward, thereby completing the automatic correction of the packaging bottle in the upper and lower directions of the bottle mouth: if the bottle mouth of the packaging bottle on the bottle supporting movable plate faces backward and downward, the bottle mouth part of the packaging bottle will be inserted into the corresponding bottle mouth limiting notch, and when the bottle supporting movable plate swings downward, the bottle mouth part of the packaging bottle remains in the limited position under the bottle mouth limiting notch, and the packaging bottle The bottom of the bottle will gradually swing downward and tilt (the bottle swings downward around the bottle mouth with the bottle limiting plate as the fulcrum, and when the bottle mouth of the bottle is separated from the bottle mouth limiting notch, the bottle bottom is at the lower side of the bottle mouth), and then slides down along the lower inner wall of the bottle sorting bucket, thereby automatically correcting the bottle to an upright state with the bottle mouth upward and the bottle bottom downward; if the bottle mouth of the bottle on the bottle supporting movable plate is tilted toward the upper front, the bottle bottom of the bottle cannot pass through the bottle mouth limiting notch and is supported by the bottle limiting plate. When the bottle supporting movable plate swings downward around its side, the bottle slides down from the rear end of the plastic bottle sorting groove, and the bottle bottom is at the lower side of the bottle mouth, and then slides down along the lower inner wall of the bottle sorting bucket, thereby automatically correcting the bottle to an upright state with the bottle mouth upward and the bottle bottom downward, and finally, the bottle comes out from the lower end of the bottle sorting bucket in an upright state.
