At present, the stretching and sealing device at the blow molding process in the rotary bottle blowing machine comprises a frame 100, a sliding component 101 capable of sliding up and down relative to the frame is arranged on the frame 100, a stretching rod 102 vertically arranged is connected to the sliding component 101, a lifting component 103 capable of moving up and down relative to the frame 100 is also connected to the lower part of the sliding component 101 and the frame 100, a vertical downward sealing shaft 105 is arranged on the lifting component 103, the stretching rod 102 penetrates through the lifting component 103 and the sealing shaft 105 and then penetrates out from the bottom of the sealing shaft 105, a roller 104 is further arranged on the lifting component 103, a cam component is arranged on one side of the roller 104, the cam component comprises cam slide ways 106 symmetrically arranged up and down, and the roller 104 stretches into the space between the upper cam slide ways 106 and contacts with the upper cam slide way 106 and the lower cam slide ways 106, as shown in fig. 1 and 2. When the bottle blank needs to be stretched and sealed, the sliding component 101 moves downwards to drive the stretching rod 102 to move downwards to stretch the bottle blank, then the roller 104 slides along the cam component to drive the sealing shaft 105 to descend so as to seal the stretched bottle, after the bottle is prepared, the sliding component 101 ascends to drive the stretching rod 102 to ascend, and the roller 104 continues to slide along the cam component to drive the sealing shaft 105 to ascend. Because the lifting of the sealing shaft 105 is realized through the cooperation of the roller 104 and the cam component, the cam component has high processing difficulty and high processing precision requirement, so the processing cost is very high, the roller is easy to wear in the long-time sliding process, the service life is short, the sealing shaft is easy to lift and fall in place, the bottle forming quality is reduced, and in addition, the roller has very loud noise when sliding on the cam component, so the working environment is seriously influenced.
Disclosure of Invention
The invention aims to provide a stretching and sealing linkage device which reduces processing difficulty, improves bottle forming quality and reduces working noise.
The invention discloses a stretching and sealing linkage device of a rotary bottle blowing machine, which comprises a frame, wherein a sliding component capable of moving up and down relative to the sliding component is arranged on the frame, a stretching rod which is vertically arranged is connected to the sliding component, a lifting component capable of moving up and down relative to the frame is also connected to the lower part of the sliding component, a vertical downward sealing shaft is arranged on the lifting component, the stretching rod penetrates through the lifting component and the sealing shaft and then penetrates out of the bottom of the sealing shaft, a linkage mechanism which enables the sealing shaft to lift along with the sliding component is arranged between the lifting component and the sliding component, the linkage mechanism comprises a connecting plate connected to the lifting component, a connecting rod is vertically connected to the connecting plate, a positioning block is arranged on the sliding component, a top plate is arranged at the top of the frame, the connecting rod penetrates through the positioning block and the top plate sequentially and can slide up and down relative to the positioning block and the top plate, a spring pressing sleeve is arranged on the connecting rod, a spring is arranged between the top plate and the spring pressing sleeve, and the spring is in a compressed state when the sliding component is not lowered.
According to the stretching and sealing linkage device of the rotary bottle blowing machine, when a bottle blank is required to be stretched and sealed, the sliding component descends to drive the stretching rod to move downwards, and meanwhile, the positioning block descends, and after the positioning block descends, the spring is not compressed any more, at the moment, the elastic restoring force generated by the spring in the elastic restoring state is matched with the lifting component and the gravity of the linkage mechanism, so that the lifting component drives the sealing shaft to rapidly descend and seal the bottle within a specified time, and the preparation of the bottle is completed; and then the sliding component ascends to drive the stretching rod to return to the original position, meanwhile, the positioning block is also driven to ascend, after the positioning block is contacted with the spring pressing sleeve on the connecting rod, the lifting of the lifting component and the sealing shaft can be realized, and meanwhile, the spring pressing sleeve compresses the spring again, so that the potential energy is accumulated by the spring to prepare for the next sealing. Through the link gear, make lifting unit and the subassembly linkage of sliding, avoid using cam assembly, consequently, reduced the machining precision by a wide margin, reduced the processing degree of difficulty, make processing cost reduce by a wide margin, simultaneously, because no longer use cam assembly and gyro wheel's cooperation to realize sealed axle along with lifting unit's lift, consequently reduced operational environment's noise by a wide margin, and realize lifting unit and the synchronous lift of subassembly of sliding through the link gear, the wearing and tearing phenomenon that produces when having effectively avoided using the gyro wheel causes the poor problem of bottle shaping quality.
