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 discharging connection mechanism. Background Art

[0002] At present, most of the bottle blowing machines are still two-step bottle blowing machines, that is, the plastic raw materials must be made into bottle embryos first, and then the bottle embryos (embryos) are blown. After being irradiated by infrared high-temperature lamps, the embryo body of the bottle embryo is heated and softened, and then placed in the prepared blow mold, and high-pressure air is inflated inside, and the bottle embryos (embryos) are blown and pulled into the required bottles. The formed bottles are taken from the heating head by the bottle-taking robot parts and placed in this mechanism. Under the action of wind force, the bottles slide along the guide rails composed of the translational bottle receiving guide rail and the rotating bottle receiving guide rail. Transfer to the subsequent equipment after the bottle blowing machine (air duct, filling machine, labeling machine, etc.) to perform the next process. This mechanism is the link between the bottle blowing machine and the rest of the manufacturer's equipment. Most of the bottle discharge connection mechanisms currently on the market are:

[0003] 1. Double cylinder drive, that is, two cylinders 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 gas source and the resistance of the sealing ring are inconsistent, and also because of the change of gas compression, it is difficult to ensure synchronization;

[0004] 2. Driven by a single cylinder, the translational and rotating side panels on both sides are connected by a connecting rod in the middle, and the opening and closing actions are realized by the cylinder driving the connecting rod. Because the closing position is controlled by adjusting the threaded cylinder control, it is affected by the changes in gas compression and the stability of the gas source. The closing position will change each time, resulting in poor dimensional stability of the guide rail pair composed of the transfer bottle guide rail and the rotating bottle guide rail. The bottle is easily stuck due to the small gap and cannot be moved, or it falls from the guide rail pair due to the large gap of the guide rail pair.

[0005] Both of the above mechanisms have relatively large stability in the movement size of the cylinder, resulting in unstable and jittery closing positions each time, affecting the capacity and production continuity of the bottle blowing machine. Summary of the invention

[0006] In view of this, the main purpose of the present invention is to provide a synchronous opening and closing bottle discharging connection mechanism.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A synchronous opening and closing bottle discharging connection mechanism, comprising

[0009] A set of corresponding fixed plates,

[0010] The cylinder is arranged at the lower part of one of the fixed plates.

[0011] The cylinder push rod set on the cylinder is fixed to the guide rail fixing seat through a floating joint.

[0012] A group of opening and closing track plates are respectively fixed on the left and right ends of the upper part of the guide rail fixing seat. Each opening and closing track plate is provided with an opening and closing guide rail with a Z-shaped curve. An opening and closing guide shaft is provided in each opening and closing guide rail. The upper part of the opening and closing guide shaft is fixed to the translation connecting plate. The left and right sides of the translation connecting plate are arranged between a group of translation side plates.

[0013] A slider is disposed on the outer side of each translation side plate, each of the sliders is fixed on a Y guide rail, and each of the Y guide rails is disposed on the inner side of the fixed plate on the corresponding side.

[0014] A set of corresponding opening and closing connecting rods, one end of each opening and closing connecting rod is fixed to the lower part of the translation side plate, and the other end is fixed to a rotating side plate, and the rotating side plate is fixed to the inner side of the fixed plate.

[0015] Driven by the cylinder, the cylinder push rod drives the guide rail fixing seat to move left and right through the floating joint, so that a set of opening and closing guide rails installed on the guide rail fixing seat move along the X direction, and the opening and closing guide shaft moves along the Z-shaped curve in the opening and closing guide rail. The X-direction movement output by the cylinder is converted into the Y-direction movement of the translation connecting plate and the translation side plate through the movement of the opening and closing guide shaft along the Z-shaped curve in the opening and closing guide rail. At the same time, the opening and closing connecting rod fixed on the translation side plate drives the rotating side plate to rotate along the axis of the rotating connecting rod to realize the opening and closing action of the whole mechanism.

[0016] Furthermore, a translation bottle receiving guide rail connecting the two translation side plates is provided on the upper part of the group of translation side plates;

[0017] The first translation bottle receiving limiting rod is arranged between a group of translation side plates, and the first translation bottle receiving limiting rod is located at the lower part of the translation bottle receiving guide rail.

[0018] Furthermore, a rotating bottle receiving guide rail connecting two rotating side plates is provided on the upper part of a set of rotating side plates.

[0019] A second translation bottle receiving limiting rod is arranged between a group of translation side plates, and the second translation bottle receiving limiting rod is located at the lower part of the rotating bottle receiving guide rail;

[0020] The blowing aluminum plate is arranged between a group of the rotating side plates, and the blowing aluminum plate is located at the lower part of the rotating bottle receiving guide rail and at the upper part of the second translation bottle receiving limiting rod.

[0021] The main air blowing pipe is set inside the air blowing aluminum plate.

[0022] A plurality of blowing pipes are arranged on the main blowing pipe.

[0023] Furthermore, each of the fixing plates includes a first arm at the bottom and a second arm at the top of the first arm.

[0024] The cylinder is arranged on the first support arm.

[0025] The Y guide rail is horizontally arranged along the Y direction of the second supporting arm.

[0026] Furthermore, a cam is provided at the lower portion of the opening and closing guide shaft, and the cam is fixed in the opening and closing guide rail of the Z-shaped curve.

[0027] Further, a rotary bearing is arranged on the second arm of the fixed plate,

[0028] The lower part of the rotating side plate is fixed in a rotating bearing arranged on the second supporting arm through a first rotating connecting rod.

[0029] Furthermore, a connecting rod bearing is provided on the opening and closing connecting rod.

[0030] The lower part of the rotating side plate is fixed in a connecting rod bearing arranged on the opening and closing connecting rod through a second rotating connecting rod.

[0031] Beneficial effects:

[0032] This mechanism uses a cylinder to drive the opening and closing guide shaft, and the cam in the opening and closing guide rail controls the opening and closing stroke. The cam moves in a curve to ensure that the opening and closing process is uniform, so the stability is better. The cam has a certain movement margin, that is, the cylinder action stroke is too large and does not affect the position change of the opening and closing, which is suitable for high-speed action.

[0033] The present invention realizes the opening and closing action of the whole mechanism by driving the two sets of opening and closing guide rails installed on the guide rail fixing seat to move in the X direction under the drive of the cylinder, and the opening and closing guide rails drive the guide rail connecting rods to convert the X-direction movement of the cylinder into the Y-direction movement of the translation connecting plate and the left and right translation side plates, and at the same time, the opening and closing connecting rods fixed on the left and right translation side plates drive the left and right rotation side plates to rotate along the axis of the rotation connecting rods. The cylinder drives the opening and closing guide shaft and the opening and closing guide rails to form a cam mechanism to control the opening and closing stroke, and the cam moves in a curve to ensure that the opening and closing process is uniform.
