Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 to 4, a vacuum chamber opening and closing mechanism of a packaging machine includes:
a turntable;
the first end of the connecting rod is fixedly arranged on the turntable;
the first end of the swing rod is rotatably arranged on the second end of the connecting rod;
one end face of the cam is a working end face, and a section of sunken section is arranged on the working end face;
the sliding block is arranged near the middle part of the swing rod and can slide on the working end surface of the cam;
a first end of the pull rod is hinged with a second end of the swing rod;
the swinging block is arranged on the movable cover, and the second end of the pull rod is hinged with the swinging block.
The periphery of the turntable is provided with a series of connecting rods, swing rods, sliding blocks and pull rod assemblies. Through a series of connecting rods, pendulum rods, slider and the pull rod subassembly of periphery setting, set up a plurality of stations, continuous work, work efficiency is high.
The turntable is rotatably arranged on the frame, and the cam is fixedly arranged on the frame. The cam is fixed, and the turntable rotates to drive the sliding block to rotate on the cam.
The cam is circular ring shape, and one section of the circular ring shape cam is a sunken section. The concave section and the size increasing section drive the sliding block to move, so that the pull rod is driven to move.
The slider is sleeved with a roller, and the roller can roll on the working end face of the cam. The roller can reduce frictional resistance.
During operation, when the sliding block moves to the size increasing section from the concave section, the sliding block moves downwards to drive the second end of the swinging rod to move downwards, so that the pulling rod is pulled, the swinging block of the movable cover is pulled by the pulling rod, the movable cover moves upwards, the movable cover is matched with the fixed block to close the cover, and when the sliding block moves to the concave section from the size increasing section, the movable cover moves downwards under the action of gravity to open the cover.
After the structure is adopted, all the movable covers are driven by one cam, the synchronism is good, and the work is reliable.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
