In the above, the swing arm gear, the swing arm and the roller fixing block at the end close to the roller fixing block are fixed by screws.
In the above, the swing arm gear, the swing arm and the swing arm spring mounting block at the end near the swing arm spring mounting block are fixed by screws.
In the above, the guide sleeve assembly includes a roller fixing block 19, the roller fixing block is U-shaped, the opening of the roller fixing block faces upward, a gripper bearing 3 is disposed in the roller fixing block, a gripper bearing fixing shaft 9 is disposed in the gripper bearing, the gripper bearing fixing shafts are fixed at two ends of the roller fixing block, and a guide sleeve 20 is disposed outside the gripper bearing.
In the above, guard plates 25 are provided on both front and rear sides of the slider fixing plate. The guard plate 25 is used for fixing the two swing arm racks and the swing arm gear 14 on the slider fixing plate 6. The rotating shaft 26 penetrates through a limiting groove arranged in the guard plate 25, and the limiting groove is used for limiting the up-down moving position of the rotating shaft 26, so that the opening and closing sizes of the two swing arms are limited.
In the above, the guide sleeve is driven under the action of external force, the swing arm gear which drives one side close to the guide sleeve takes the rotating shaft as a fulcrum, the swing arm gear on one side drives the rack to move up and down and simultaneously drives the swing arm on the other side to move synchronously, the swing arms on two sides take the rotating shaft as a central line to move synchronously, so that the bottle blank gripper is opened synchronously, the compression spring on one side is compressed under the action of the swing arm spring mounting block, the compression spring on the other side is compressed under the action of the roller fixing block, and when the external force disappears, the two swing arms are closed under the action of the compression spring.
The invention forms a working group unit (which can be used in a single group) by a plurality of groups of diameter-changing mechanism synchronous clamping hand mechanisms, when a guide sleeve of the diameter-changing mechanism synchronous clamping hand mechanism unit is driven under the action of external force (power source), a swing arm gear on one side is driven, a swing arm gear on one side drives a rack to move up and down and simultaneously drives a finger swing arm on the other side to move, swing arms on two sides synchronously move with the circle center of the gear (the central line of the middle rotating shaft), the bottle blank clamping hand is synchronously opened, a bottle blank is clamped at a heating chain (short pitch) position, and when the external force disappears, the whole set of swing arms are closed under the action of a spring.
The opening and closing trajectory is shown in fig. 1 and 2. Because the opening and closing track is round, namely, the joint point of the two parts of the clamping hand is the vertex of the circle, namely, the opening and closing process, the clamping hand moves outwards along the round track (when the clamping hand opens and closes along the X direction, the clamping hand moves downwards along the Y direction), when the bottle embryo 24 is picked up, the Y-direction acting force cannot be applied to the bottle embryo, and because of the bilateral symmetry action of the clamping hand, the X-direction acting force can be mutually offset. The bottle embryo falls into the clamping hand of the diameter-changing mechanism synchronous clamping hand mechanism under the action of self gravity, no other external force is applied, the joint point of the clamping hand is the highest point of the circular track, and the bottle embryo cannot be pushed when being picked up, so that the bottle embryo picking up process is more accurate and stable.
Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen in order to best explain the principles of the embodiments, the practical application, or improvements made to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
