Description
Technical field
The present invention relates to plastic bottle blowing molding machine field of mechanical technique, what particularly relate to a kind of bottle blowing machine carries out to bottle embryo the mechanism that stretches Yu seal.
Background technology
Bottle blowing machine is the equipment in the plastic bottle processing and manufacturing fields such as beverage bottle, oil bottle, medicine bottle, and bottle blowing machine comprises the stretching bar stretched to bottle embryo, and stretching bar connects draft cylinder and drives work by it, stretching bar is equipped with the limited block of adjustment stretching depth; Have the closing component of shutoff bottleneck, closing component connects sealing cylinder, the action that sealing cylinder drives closing component that bottleneck is realized to sealing or opens.During work, stretching bar and closing component are driven by draft cylinder and sealing cylinder respectively and complete corresponding stretching and sealing work, and draft cylinder and sealing cylinder are then connected air compressor and provide compressed air as power by it.
Existing bottle blowing machine adopts pneumatic stretching and sealing, but because the pressure of source of the gas momentarily changes in the course of the work and fluctuates, the action carrying out high-speed stretch and sealing is caused to be affected and to produce fluctuation, limit the accuracy of its action, so bottle blowing machine needs to consider according to various setup parameter when designing, rotating speed is controlled within certain scope.Particularly in the making of below 600ml beverage bottle, the rotating speed of bottle blowing machine can only control in relatively low level, but and the beverage bottle of this specification limit has the call, this greatly constrains output and the production efficiency of separate unit bottle blowing machine, can not meet market demand.
Summary of the invention
The present invention aims to provide a kind of Mechanical Driven and stretches and the blowing machine stretching sealed and enclosed mechanism, to improve the action accuracy of bottle blowing machine high-speed stretch and sealing, and then improves working speed and production efficiency.
The stretching of bottle blowing machine of the present invention and enclosed mechanism, comprise stretching support, be arranged on the cam tracks on bottle blowing machine mainframe, and the guide wheel rolled between cam tracks, the bearing block that cover has leading screw stretching support is equipped with, leading screw connects the drive motors driving its motion, has the stretching rod bearing that stretching bar is housed, stretching rod bearing is equipped with the feed screw nut with leading screw routing motion; Stretching support is also equipped with line slideway, line slideway is equipped with linear bearing, the wheel stand that guide wheel is housed to be arranged on linear bearing and along its lifting, the hollow blowpipe assembly that bottle embryo is blown wheel stand is equipped with, the lower end of hollow blowpipe assembly connects the closing component of shutoff bottleneck, the upper end of stretching bar is fixed on stretching rod bearing, and the lower end of stretching bar can be stretched in bottle embryo through hollow blowpipe assembly and closing component.
The stretching of bottle blowing machine of the present invention and enclosed mechanism, cam tracks is fixedly mounted on the mainframe of bottle blowing machine, stretching support installing on the rotating mechanism of bottle blowing machine and with its rotate, the guide wheel be arranged on stretching support then rolls in the process of rotating between cam tracks, drive in the process that guide wheel rolls along the curve of cam tracks wheel stand and hollow blowpipe assembly mounted thereto and closing component linearly bearing move up and down, then can the bottleneck of shutoff beverage bottle when closing component declines, when closing component rises then for opening the bottleneck of beverage bottle, meanwhile, drive motors drives the guide screw movement be installed on bearing block, and leading screw drives stretching rod bearing and stretching bar to move up and down by feed screw nut, can stretch in bottle embryo stretch to it when stretching bar declines.During work, mould rotates to sending embryo station, and guide wheel rises along cam tracks and drives closing component to promote, and bottle embryo is sent within mould; After sending embryonic knob bundle, guide wheel declines along cam tracks, makes the bottleneck of closing component shutoff bottle embryo; Mould continues to rotate to the station that stretches, and closing component is by hollow blowpipe assembly ventilation to reach required sealing pressure, and meanwhile, drive motors drives stretching bar to decline by leading screw, feed screw nut, stretching rod bearing, and stretching pole pair bottle embryo stretches; After a bottle embryo has stretched, drive motors has driven the rising of stretching bar to reset again, so far completes the stretching of bottle embryo, and mould rotates to getting bottle and sending embryo station to carry out again subsequent work circulation again.The stretching bar of this mechanism and closing component adopt motor to drive respectively and roller and guide rail drive, these two kinds of type of drive are Mechanical Driven, its motion process precision is high, speed is fast, accurate adjustment can be realized, avoid the issuable problems of pneumatic actuation, rotating speed can be greatly improved, and then improve output and production efficiency, meet production & marketing needs; Tensile part is stretched by Electric Machine Control, and during high-speed cruising, stretching depth can be done accurately to control and adjustment, is conducive to improving product percent of pass and product quality.
