Synchronous opening and closing bottle outflow connecting line mechanism

Abstract

The invention discloses a synchronous opening and closing bottle outflow connecting line mechanism which comprises a left fixing plate, a right fixing plate, a left horizontal moving side plate, a right horizontal moving side plate, a horizontal moving bottle receiving guide rail, a left rotating side plate, a right rotating side plate, a rotating bottle receiving guide rail, a horizontal moving connecting plate, an opening and closing guide shaft, opening and closing guide rails, a guide rail fixing base, an opening and closing connecting rod and a rotating connecting rod. The whole mechanismis fixed to a machine table through the left fixing plate and the right fixing plate, under driving of an air cylinder, the two opening and closing guide rails installed on the guide rail fixing basemove in the X direction, the opening and closing guide rails drive the guide rail connecting rod, and x-direction movement of the air cylinder is converted into Y-direction movement of the horizontalmoving connecting plate and the left and right horizontal moving side plates. Meanwhile, the left and right rotating side plates are driven to rotate along the axis of the rotating connecting rod through the opening and closing connecting rod fixed to the left and right horizontal moving side plates to realize the opening and closing actions of the whole mechanism.

Description

technical field [0001] The invention relates to the technical field of a linear bottle blowing machine, in particular to a synchronous opening and closing bottle outlet connection mechanism. Background technique [0002] At present, most blow molding machines are still two-step blow molding machines, that is, the plastic raw materials must be made into preforms first, and then blown. After being partially heated and softened, it is placed in the blow mold that has been prepared, and the inside is inflated with high pressure to blow and stretch the preform (embryo) into the required bottle. The formed bottle is removed from the heating head by the bottle-taking manipulator and placed in the mechanism. Under the action of the wind, the bottle slides along the guide rail pair composed of the translational bottle receiving guide rail and the rotating bottle receiving guide rail. Transfer to the follow-up equipment after the blow molding machine (air duct, filling machine, sle...

AI Technical Summary

Problems solved by technology

[0003] 1. Double cylinder drive, that is, two cylinders independently drive the translation and rotation of the side plates on both sides to realize the opening and closing action. Because the two cylinders start and stop synchronously, the air source and the resistance of their own sealing rings are inconsistent, and also due to the gas compression. Changes, it is difficult to ensure that synchronization is in place;

[0004] 2. Driven by a single cylinder, the translation and rotation side plates on both sides are connected by a connecting rod in the middle, and the opening and closing action is realized by driving the connecting rod through the cylinder. Because the closed position is controlled by adjusting the threaded cylinder control, it is affected by the change of gas compression and the stability of the gas source , the closed position will change every time, resulting in poor dimensional stability of the guide rail pair composed of transfer bottle guide rail and rotary bottle transfer guide rail. Falling from the rail pair

[0005] Both of the above two mechanisms are due to the large stability of the movement size of the cylinder, resulting in unstable and jittering closing positions each time, affecting the productivity and continuity of production of the blow molding machine.
