Stretching and sealing linkage device of bottle blowing machine

Abstract

The invention discloses a stretching and sealing linkage device of a bottle blowing machine. The stretching and sealing linkage device comprises a support, a first guide rail arranged on the support and extending in the first direction, a stretching mechanism and a sealing mechanism, and the stretching mechanism comprises a first sliding block arranged on the first guide rail and a first rotor arranged on the first sliding block; the sealing mechanism comprises a sealing cylinder arranged on the support, a sealing shaft arranged in the sealing cylinder in a penetrating mode, a second sliding block arranged on the first guide rail and used for being connected with the sealing shaft, a second rotor arranged on the second sliding block, a second guide rail arranged on the support and extending in the second direction, and a third sliding block arranged on the second guide rail. The third sliding block is provided with a first cam curve and a second cam curve which are respectively matched with the first rotor and the second rotor to rotate; when the first sliding block slides relative to the third sliding block, the first rotor abuts against the first cam curve all the time. According to the stretching and sealing linkage device of the bottle blowing machine, the moving components are few, the debugging difficulty is low, the moving precision is high, and the moving stability is good.

Description

technical field [0001] The invention relates to the technical field of bottle blowing, in particular to a stretch sealing linkage device of a bottle blowing machine. Background technique [0002] With the development of blow molding machines towards high speed and low noise, the requirements for the motion precision of each mechanism of blow molding machines are getting higher and higher. During the execution of a bottle blowing action, it is necessary to continuously complete the lifting action of the sealing cylinder and the stretching rod. The lifting action of the sealing cylinder of the existing equipment is powered by a cylinder or a cam, and the lifting action of the stretching rod is powered by a cylinder or a servo motor. The two actions have two different powers, the structure is complex, and the guarantee of installation accuracy is poor, which has a certain impact on the high-speed and stable operation of the equipment. [0003] At present, there are devices tha...

AI Technical Summary

Problems solved by technology

In this device, after sealing, the rotor and the slider will be separated from each other, and the slider will continue to move down to cooperate with the stretching, which leads to the fact that after the stretch blowing is completed, the slider will move up and hit the rotor, resulting in poor movement accuracy Low, poor motion stability; and there are many equipment parts, it is difficult to debug
