Description

The rotary type multi-station plastic draw-blow machine get a bottle dial

Technical field

The utility model relates to bottle dial of getting of rotary type multi-station plastic draw-blow machine, belongs to the plastics machinery field, is applicable to the full-automatic rotary bottle blow-moulding machine of processing plastic raw materials such as PET.

Background technology

With plastics such as PET is raw material, be processed into hollow container through annotating, draw, blowing, as mineral water bottle, oil bottle etc., at first form the bottle pipe by injection machine, with bottle pipe process post bake, stretch blow-molded to the bottle pipe after the heating again by the stretch blow machine, so its capital equipment is an injection machine, heater and stretch blow machine.The bottle pipe can be delivered to heater automatically through manipulator, by manipulator the bottle pipe after heating is delivered to the stretch blow machine from heater again, the stretch blow shaped bottle is taken out from the stretch blow machine again, forms the full-automatic plastic bottle blowing machine.Shaped bottle after having a class stretch blow machine to stretch blow is sent outside the stretch blow machine mould by manipulator, by another group withdrawing device the shaped bottle of sending mould is taken out again, purpose by withdrawing device is to make the moulding bottle get bottle in order, help next process, for example pack and put into case or enter streamline can etc.Original technology is that the device that shaped bottle takes out adopts reciprocating mechanism, is driven by stepper motor, and structure is very complicated, the volume heaviness, and the cost height, the installation, maintenance trouble, it is big particularly to occupy the space, makes entire equipment not compact.Therefore, designed a kind of rotary bottle-fetching mechanism in recent years, simplify the structure, but the manipulator of existing bottle-fetching mechanism is flat manipulator, the dull and stereotyped tong of folder bottle by securing member be installed in movable component below, if in the time of will adjusting upper-lower position, need the mill pad, as add a little pads, perhaps tong is carried out grinding, generally need a few hours, relatively waste time and energy.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide in a kind of rotation and get bottle, continuous operation, simple structure, manipulator upper-lower position rotary type multi-station efficiently easy to adjust plastic draw-blow machine get a bottle dial.

The technical scheme of getting bottle dial of the utility model rotary type multi-station plastic draw-blow machine is: be mounted in rotation type multi-station tension and blow fixed hub on the machine support, rotating spindle is arranged in the axle sleeve, turning arm is installed on the top of rotating spindle, the swinging axle of two symmetries is equipped with at the turning arm two ends, line slideway is installed outside swinging axle, under the line slideway movable component is arranged, the front end of movable component is equipped with manipulator, back-moving spring is equipped with in the side, at the top of fixed hub installation bearing seat and cam disc, be shaped on cam path on the cam disc, two rolling bearings are equipped with in the movable component bottom surface, a bearing places cam path, another bearing places the cam disc edge, it is characterized in that described manipulator is L shaped right-angle type manipulator, left tong and right tong by right-angle type are formed, be shaped on elongated slot on the vertical surface of left and right sides tong respectively, extension spring is installed at the top, outer end at movable component is shaped on fastener hole, left and right sides tong is installed on the fastener hole of movable component through elongated slot by securing member, and the front portion of left and right sides tong is shaped on the circular arc recess respectively.

The utility model rotary type multi-station plastic draw-blow machine get a bottle dial, have to be installed in rotation type multi-station tension and to blow axle sleeve and rotating spindle on the machine support, so this shaped bottle withdrawing device also must be to match with the stretch blow machine of existing rotary type multi-station.The rotating spindle rotation, the driven rotary arm rotates, thereby drives the swinging axle rotation at two ends, and cam is installed on the axle sleeve by supporting base, does not rotate during work.When movable component (prior art) under the cam effect during protruding get bottle, back-moving spring is elongated; When movable component under the cam effect toward when retraction, under spring action, reset, thereby manipulator withdrawn reposefully.Said structure is identical with prior art, main feature is: its described manipulator is L shaped right-angle type manipulator, left tong and right tong by right-angle type are formed, be shaped on elongated slot on the vertical surface of left and right sides tong respectively, be fixed on the corresponding hole of movable component front end by screw, like this can be by realize the high and low position of rapid adjustment manipulator along moving of elongated slot, simple in structure, regulating very laborsavingly, and is any adjusting, very accurate.Extension spring is arranged at the vertical surface top at left and right sides tong, and the dull and stereotyped front portion of left and right sides tong is shaped on the circular arc recess respectively.Spring is strained left tong and right tong during normality, when bottleneck is run into left and right sides tong, because the inertia force plastics spout got in the circular arc recess that left and right sides tong surrounded, and spring reset, thus clamp bottleneck.On its described swinging axle bearing is housed, bearing has sleeve and bearing (ball) cover to be fixed in the turning arm outward, thereby guarantees that swinging axle can axioversion.
