Description
Technical Field
[0001] The utility model relates to the technical field of packaging machinery, in particular to a bottle mouth rotation 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] The bottle unscrambler sorts the randomly stacked bottles and arranges them in order and direction on the conveyor belt, and transfers the bottles to other machines for the next process (such as filling, labeling, boxing, etc.) at high speed and efficiency to improve the production efficiency of the entire production line.
[0004] At present, for bottles with pull tabs at the mouth of the bottle (the pull tabs are used to open the bottle mouth), in order to facilitate the subsequent conveying, labeling and outer packaging operations, it is generally necessary to make the pull tabs on each bottle completely consistent in direction. However, when unscrambling bottles, the existing bottle unscrambler cannot perform rotation correction on the direction of the pull tabs on such bottles and adjust the pull tabs on the bottles to face a specific direction. Based on this, in order to meet the requirements of unscrambling such bottles, it is necessary to develop a bottle mouth rotation correction mechanism that can make the pull tabs on the bottles face a specific direction. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a bottle mouth rotation correction mechanism, which can automatically perform rotation correction on a packaging bottle with a pull tab at the bottle mouth, so that the pull tab on the packaging bottle faces a specific direction, so as to facilitate subsequent operations such as conveying, labeling and outer packaging. The adopted technical solution is as follows:
[0006] A bottle mouth rotation correction mechanism, characterized in that it comprises a frame and a lifting and rotating bottle device, the lifting and rotating bottle device comprises a lifting seat, a lifting mechanism for driving the lifting seat to lift and lower, at least one bottle mouth limiting sleeve, a rotating mechanism for driving each bottle mouth limiting sleeve to rotate, and at least one bottle mouth limiting component, the lifting mechanism is installed on the frame, and the rotating mechanism is installed on the lifting seat; the rotation axis of the bottle mouth limiting sleeve is in an up-and-down direction, a bottle mouth accommodating cavity is provided on the bottom surface of the bottle mouth limiting sleeve, and a bottle rotating block is provided on the inner side wall of the bottle mouth accommodating cavity; the number of the bottle mouth limiting components is the same as that of the bottle mouth limiting sleeves and they correspond one to one, the bottle mouth limiting components are installed on the lifting seat and are located at the lower side of the corresponding bottle mouth limiting sleeves.
[0007] Typically, the inner wall of the bottle mouth accommodating cavity is a revolving surface (such as a cylindrical surface, a frustum or a revolving curved surface (such as a hemispherical surface)) with the rotation axis of the bottle mouth limiting sleeve as the center line; the bottle mouth accommodating cavity can be used for the bottle mouth of the packaging bottle and its upper pull tab to be inserted.
[0008] The bottle-end stopper is then driven by the lifting mechanism to move the lifting seat, the rotating mechanism and the bottle-end stopper sleeve upwards and downwards, so that the bottle-end stopper sleeve is sleeved on the bottle-end position and the pull-tab of the bottle-end through its bottle-end accommodating cavity, and then the bottle-end stopper sleeve is driven by the rotating mechanism to rotate one circle and then stop rotating. In this process, since the position of the bottle-end stopper sleeve is lower than the bottle-end stopper sleeve and the bottle-end stopper block, it will not affect the rotation of the bottle-end stopper sleeve, and no matter which direction the pull-tab at the bottle-end of the bottle-end faces, the bottle-end stopper block will drive the bottle to rotate after contacting the pull-tab, until the bottle-end stopper sleeve stops rotating after contacting the bottle-end stopper sleeve (at this time, the bottle-end stopper block and the bottle-end stopper sleeve jointly define the position of the pull-tab), so that the pull-tab on the bottle faces a certain direction; then, the lifting mechanism drives the lifting seat, the rotating mechanism and the bottle-end stopper sleeve upwards and resets, so as to prepare for rotation correction of the next bottle. Therefore, the bottle mouth rotation correction mechanism can automatically perform rotation correction on the packaging bottle with a pull tab at the bottle mouth, so that the pull tab on the packaging bottle faces a specific direction, so as to facilitate subsequent operations such as conveying, labeling and outer packaging.
[0009] As a preferred embodiment of the utility model, the bottle mouth limiting component includes a bottle mouth limiting rod, which is arranged on the lower side of the bottle mouth limiting sleeve along the inner and outer directions, and the outer end of the bottle mouth limiting rod is connected to the lifting seat through a connecting rod. The inner and outer directions refer to: the end close to the rotation axis of the bottle mouth limiting sleeve is the inner side, and the end away from the rotation axis of the bottle mouth limiting sleeve is the outer side. When the bottle mouth limiting sleeve is sleeved on the bottle mouth part and the pull tab of the packaging bottle through its bottle mouth accommodating cavity, the inner end of the bottle mouth limiting rod does not contact the bottle mouth part of the packaging bottle, and the inner end of the bottle mouth limiting rod is on the rotation path of the pull tab; when the packaging bottle rotates under the push of the bottle rotating block, the inner end of the bottle mouth limiting rod does not affect the rotation of the packaging bottle and its pull tab, until the pull tab stops rotating when it contacts the inner end of the bottle mouth limiting rod.
[0010] As a preferred solution of the utility model, there are multiple bottle mouth limiting sleeves, and each bottle mouth limiting sleeve is arranged in sequence from left to back. Therefore, the bottle mouth rotation correction mechanism can complete the rotation correction operation of multiple packaging bottles with pull tabs at the bottle mouth at one time, which can improve work efficiency.
[0011] As a preferred solution of the utility model, the rotating mechanism includes at least one rotating shaft, at least one transmission gear, a spur rack, and a rack translation mechanism for driving the spur rack to translate left and right.

The spur rack is arranged in the left-right direction, and each transmission gear is meshed with the spur rack. The center line of the rotating shaft is the rotation axis of the bottle mouth limiting sleeve. When working, the rack translation mechanism drives the spur rack to translate left or right, and uses the meshing relationship between each transmission gear and the spur rack to drive each transmission gear to rotate, and then drives each bottle mouth limiting sleeve to rotate through each rotating shaft.

When the lifting mechanism drives the lifting seat and the rotating mechanism and the bottle mouth limiting sleeve thereon to descend, the bottle mouth limiting sleeve is sleeved on the bottle mouth part and the pull tab through its bottle mouth accommodating cavity. During this process, the bottle mouth part of the packaging bottle will press against the lower ejector block, so that the lower ejector block and the bottle ejector rod move upward (the screw of the limiting bolt is in the annular groove, which can limit the up and down travel of the bottle ejector rod); when the lifting mechanism drives the lifting seat and the rotating mechanism and the bottle mouth limiting sleeve thereon to ascend, the bottle ejector rod and the lower ejector block move downward under the action of their own gravity, exert a downward force on the bottle mouth part of the packaging bottle, so that the bottle mouth part can be smoothly separated from the bottle mouth limiting sleeve.

Therefore, in the process of the lifting and rotating bottle device rotating and correcting the pull tabs at the bottle mouths of each packaging bottle, each limiting rod group can limit the bottle body of the packaging bottle respectively, so as to avoid the situation that the position of the packaging bottle is offset or even tipped over during the rotation correction process, which is conducive to ensuring the smooth progress of the rotation correction work. After completing the rotation correction work, the two left and right translation mechanisms drive the two second translation seats to translate, driving the two left limit rods and the two right limit rods of the limit rod group to move backwards, so that the distance between the left limit rod and the right limit rod becomes larger (usually larger than the size of the bottle body), so that the bottle can be moved out from between the left limit rod and the right limit rod.

[0036] The following is a brief description of the working principle of this bottle mouth rotation correction mechanism:
[0037] During operation, the packaging bottle 100 can enter the bottle body accommodating cavity from the top of the bottle body accommodating cavity. At this time, the packaging bottle 100 is supported by the bottle supporting bottom plate 26, and the two left limiting rods 231 and the two right limiting rods 232 of the limiting rod group 23 jointly limit the bottle body of the packaging bottle 100; then, the front and rear translation mechanism 22 drives the bottle feeding translation frame 21 and the two left and right translation mechanisms 25, the two second translation seats 24 and each limiting rod group 23 to translate forward, and the packaging bottle 100 in each limiting rod group 23 is transported to the bottom of each bottle mouth limiting sleeve 33; then, the lifting mechanism 32 of the lifting and rotating bottle device 3 drives the lifting seat 31 and the rotating mechanism 34 and the bottle mouth limiting sleeve 33 thereon. 3, so that the bottle mouth limiting sleeve 33 is sleeved on the bottle mouth part 101 and the pull tab 102 of the packaging bottle 100 through its bottle mouth accommodating cavity 331 (at this time, the bottle mouth part 101 of the packaging bottle 100 will support the lower ejector block 347, so that the lower ejector block 347 and the bottle ejector rod 345 move upward), and then the rack translation cylinder 3441 of the rack translation mechanism 344 drives the first translation seat 3442 and the spur rack 343 to translate leftward or rightward along the rack guide sleeve 3443, and the meshing relationship between each transmission gear 342 and the spur rack 343 is utilized to drive the corresponding rotating shaft 341 and the bottle mouth limiting sleeve 33 thereon to rotate one circle through each transmission gear 342 and then stop rotating. During the process, since the position of the bottle mouth limiting component 35 is lower than the bottle mouth limiting sleeve 33 and the bottle rotating block 332, it will not affect the rotation of the bottle mouth limiting sleeve 33, and no matter which direction the pull tab 102 at the bottle mouth of the packaging bottle 100 faces, the bottle rotating block 332 will drive the packaging bottle 100 to rotate after contacting the pull tab 102, until the pull tab 102 contacts the bottle mouth limiting component 35 and the packaging bottle 100 stops rotating (at this time, the bottle rotating block 332 and the bottle mouth limiting component 35 jointly define the position of the pull tab 102), so that the pull tab 102 on the packaging bottle 100 faces a specific direction; then, the lifting mechanism 32 drives the lifting seat 31 and the rotating mechanism 34 thereon and the bottle mouth limiting component 35 to move in a certain direction. The positioning sleeve 33 rises and resets (at this time, the bottle-removing ejector rod 345 and the lower ejector block 347 move downward under the action of their own gravity, exerting a downward force on the bottle mouth portion 101 of the packaging bottle 100, so that the bottle mouth portion 101 can be smoothly separated from the bottle mouth limiting sleeve 33); after completing the rotation correction work, the two left and right translation mechanisms 25 drive the two second translation seats 24 to translate, driving the two left limiting rods 231 and the two right limiting rods 232 of the limiting rod group 23 to move backwards, so that the distance between the left limiting rod 231 and the right limiting rod 232 becomes larger (usually larger than the size of the bottle body of the packaging bottle 100), so that the packaging bottle 100 can be moved out from between the left limiting rod 231 and the right limiting rod 232.
