Abstract
The present invention relates to an automatic toe index device of a plastic injecting and blowing hollow molding machine with a one-step method. A working table is arranged on a machine base, a rotary turret is arranged on the working table, and the rotary turret is connected with a main shaft. An index plate is arranged under the main shaft, an index groove is arranged in the index plate, and the index groove is matched a poking block which is driven by the toe index device. The toe index device is a toe index box which is connected with the lower part of the working table. The toe index box is provided with a toe index oil cylinder, and the toe index oil cylinder is connected with a slide block. The slide block is connected with a rotating arm, and the rotating arm which is sheathed outside the main shaft drives a poking fork on which a poking block is arranged. The toe index device of the present invention is characterized in that the poking fork is driven by the slide block crank mechanism (rotating arm) which is driven by the oil cylinder. When the rotary turret and the main shaft are lifted, the poking block of the poking fork is clamped in the index groove of the index plate, the slide block is pushed by the oil cylinder, and the rotary turret on the main shaft is revolved for 120 DEG. The present invention has the advantages of fast and slow toe index, no gap in transmission links and no impact.
Description
Technical field
The present invention relates to the process equipment of plastic hollow vessel, mainly relate to the turn device of one-step method full-automatic plastic injection blow blow moulding machine, belong to the plastics machinery field.
Background technology
(mainly be meant PE with plastics, PP, PC) be raw material, blow through notes and to be processed into hollow container (plastic bottle), as medicine bottle, bottle for cosmetics, beverage bottle etc., existing equipment has the full-automatic plastic injection blow blow moulding machine, this machine is combined injection moulding and blowing, annotate, blow on same workbench and carry out, therefore mould is installed on the stationary work-table, another by capstan head drive workpiece the plug transposition and at injection moulding, three different stations of the blowing and the demoulding are finished, 120 ° of three mutual spacings of station, capstan head is driven by main shaft, and index dial is installed in the main shaft bottom, index dial relies on turn device to stir, and each dialling changeed 120 °.The turn device of prior art adopts gear, tooth bar and special-purpose member, and the major defect of rack-and-pinion transposition is that to exist transmission link gapped, and trueness error is big, and starting has impulsive force, and speed is wayward, and accurate positioning is poor.
Summary of the invention
The purpose of this invention is to provide a kind of slider-crank mechanism, have speed transposition characteristics, its transmission link does not have the gap, and rotating speed is slow when transposition puts in place, guarantees the shock-free one-step method full-automatic plastic injection blow of accurate positioning blow moulding machine turn device.
The technical scheme of plastic injecting and blowing blow moulding machine turn device of the present invention is: a workbench that is installed on the support is arranged, capstan head is arranged on the workbench, capstan head connects main shaft, main shaft is installed index dial down, be shaped on indexing trough in the index dial, indexing trough matches with shifting block, shifting block is driven by turn device, it is characterized in that described turn device is: be connected the transposition indexing case of workbench bottom, indexing case is installed the transposition oil cylinder, and the transposition oil cylinder connects slide block, slide block links to each other with pivoted arm, pivoted arm is enclosed within outside the main shaft, and pivoted arm drives shift fork, and shifting block is installed on the shift fork.
The turn device of the technical program is to drive shift fork by the slider crank mechanism (pivoted arm) that oil cylinder promotes, when capstan head and main shaft lift, the shifting block of shift fork snaps in the indexing trough of index dial, and slide block is promoted by oil cylinder, drive pivoted arm, make shift fork and index dial and main axis rotation, make the capstan head revolution on the main shaft reach 120 °, revolution puts in place, send signal by control system, capstan head descends, and shift fork and index dial are thrown off, and the transposition oil cylinder drives pivoted arm and resets.Originally the turn device of slide block of cranking arm is that speed transposition characteristics are arranged, and transmission link do not have the gap, the precision height, and when transposition put in place, rotating speed was slow, guaranteed that accurate positioning do not have impact.In order to make slide block movement precision height, in its transposition indexing case guide rod is installed, slide block matches with guide rod.More accurate for the location that makes transposition, spacing thimble is installed in its transposition indexing case, slide block connects pivoted arm through connecting rod, and spacing thimble contacts with the connecting portion of slide block and connecting rod.Indexing case keeps nonrotation when transposition, between its transposition indexing case and the pivoted arm swivel bearing is installed.More reliable for shift fork is connected with shifting block, its shift fork is shaped on engaging lug, and engaging lug links to each other with shifting block.
