Description
Technical field
The present invention relates to the stretchings of rotary bottle blow-moulding machine and sealing linkage.
Background technique
It is by being formed after reason embryo, heating and blow molding process that bottle embryo, which is shaped to bottle, wherein right in blow molding process
The stretching and sealing of bottle embryo are to complete with draw unit and cam pack respectively, and the effect of draw unit is that handle has heated
Bottle embryo after is stretched to preset length, forms bottle preferably in a mold, then stretching is completed by cam pack
Bottle is sealed, to form bottle.
Currently, the stretching and closing device at blow molding process in rotary bottle blow-moulding machine include rack 100, in rack 100
The stretch rod 102 being vertically arranged can be connected on sliding assembly 101 with respect to the sliding assembly 101 that it is slided up and down by being provided with,
The lower section of sliding assembly 101 and in be also connected in rack 100 can the lifting assembly 103 that moves up and down of opposite rack 100, it is described
Sealing axis 105 straight down is provided in lifting assembly 103, the stretch rod 102 is through lifting assembly 103 and sealing axis
It is pierced by after 105 by 105 bottom of sealing axis, is additionally provided with idler wheel 104 in the lifting assembly 103, be provided in 104 side of idler wheel
Cam pack, the cam pack include in upper and lower symmetrically arranged cam slideway 106, and the idler wheel 104 protrudes into lower cam
It is contacted between slideway 106 and with upper lower cam slideway 106, as depicted in figs. 1 and 2.It is sliding when needing to stretch and sealing bottle embryo
It moves component 101 to move down, stretch rod 102 is driven to move down to stretch bottle embryo, slided with rear roller 104 along cam pack, to drive
It seals axis 105 to decline, to seal the bottle for stretching completion, after the preparation for completing bottle, sliding assembly 101 rises, band
Dynamic stretch rod 102 rises, and idler wheel 104 continues to slide along cam pack, and band dynamic sealing axis 105 rises.Due to sealing axis 105
Lifting is to be realized by the cooperation of idler wheel 104 and cam pack, and cam pack difficulty of processing is big, and requirement on machining accuracy is high,
Therefore processing cost is very high, and idler wheel is also easier to wear in long-time sliding process, and not only service life is short, also holds
Easily cause sealing axis lifting not in place, cause the reduction of bottle Forming Quality, in addition, idler wheel noise when sliding on cam pack is non-
Chang great seriously affects working environment.
Summary of the invention
The present invention is intended to provide a kind of reduce difficulty of processing, promote bottle Forming Quality and reduce the stretching of operating noise
With sealing linkage.
The stretching of rotary bottle blow-moulding machine of the present invention a kind of and sealing linkage, including rack are arranged in rack
The stretch rod being vertically arranged can be connected on sliding assembly, under sliding assembly with respect to the sliding assembly that it is moved up and down by having
Side and in be also connected in rack can the lifting assembly that moves up and down of opposite rack, be provided with straight down in the lifting assembly
Sealing axis, the stretch rod through lifting assembly and sealing axis after be pierced by by sealing axis bottom, in lifting assembly and sliding group
Being provided between part makes to seal the linkage mechanism that axis is gone up and down with sliding assembly, and the linkage mechanism includes being connected in lifting assembly
Connecting plate, be connected with connecting rod vertically on connecting plate, locating piece be provided on sliding assembly, be provided at the top of rack
Top plate, the connecting rod from lower to upper successively vertically through locating piece and top plate and can relative positioning block and top plate slide up and down,
Spring press-cover is provided on connecting rod, between top plate and spring press-cover and in being arranged with spring on connecting rod, sliding assembly is not under
When drop, spring is in compressive state.
A kind of stretching of rotary bottle blow-moulding machine of the present invention and sealing linkage, are needing to stretch bottle embryo and are sealing
When, sliding assembly decline drives stretch rod to move down, while also driving locating piece decline, after locating piece decline, does not recompress
Spring, the weight of spring generates under natural resiliency recoil state at this time elastic-restoring force and lifting assembly and linkage mechanism itself
Power cooperates, and seals lifting assembly band dynamic sealing axis rapid decrease and to bottle at the appointed time, to complete bottle
The preparation of son；Subsequent sliding assembly rises, and drives stretch rod to return back to home position, while also locating piece being driven to rise, fixed
After position block is contacted with the spring press-cover on connecting rod, lifting assembly can be realized and seal the rising of axis, while spring press-cover is again
Compressed spring makes spring gather potential energy, prepares for sealing next time, in addition, when sliding assembly rises, due to having bullet
Spring can also buffer the speed and dynamics of linkage mechanism reply.By linkage mechanism, so that lifting assembly and sliding assembly is linked, keep away
Exempt from therefore, to significantly reduce machining accuracy using cam pack, reduce difficulty of processing, processing cost is greatly reduced, together
When, because the cooperation for not using cam pack and idler wheel realizes that sealing axis with the lifting of lifting assembly, significantly reduces
The noise of working environment, and by linkage mechanism realize lifting assembly and sliding assembly synchronization lifting, effectively prevent using
The wear phenomenon that is generated when idler wheel and the problem for causing bottle Forming Quality difference.
