Description
Technical field
The utility model relates to the stretch blow machine, particularly relates to falling tubular type stretch blow machine locating friction and carries heater, belongs to the plastics machinery field.
Background technology
In hollow plastic container is produced, as processing mineral water bottle, oil bottle, bottle for cosmetics etc., at first adopt injection machine that plastic raw materials is annotated and make the bottle pipe, by heater plastic bottle-pipe is heated again, then by the stretch blow machine to heating bottle pipe stretch blow moulding.Existing most plastic bottle pipe heating device is that the bottle pipe is inserted on the supporting base, supporting base is driven by operational systems such as chain or slide blocks and by the thermal treatment zone bottle pipe is heated, the shortcoming that this technology exists is a machine construction complexity not only, main is if unify with the stretch blow unit, its material loading or blanking manipulator have many groups, also damage easily, service life is short.So, developed the operation of drive plastic bottle-pipe without supporting base, but rely on friction band or friction chain to carry the heater of bottle pipe, in practice because friction band or friction chain and bottleneck are planar frictions, so can speed to occur inhomogeneous at each bottle pipe in service forward, having produced distance between each bottle pipe has and long weak point is arranged, inconsistent, not only influence the thermal effect that adds of bottle pipe, and bring difficulty entering stretch blow machine operation.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of positioner that is provided with in driving chain is provided, make each bottle pipe arrangement pitches even when driving the plastic bottle-pipe operation, and the rotation of bottle pipe is reliable, heats the effective tubular type stretch blow machine locating friction that falls and carry heater.
The utility model tubular type stretch blow machine locating friction that falls carries the technical scheme of heater to be: comprise the mould bases that is installed in the frame; template and Stretch and Blow Mechanism are installed on the mould bases; template is driven by clasp mould mechanism; installation mold in the template; above a side of template, heater is installed; herringbone is installed between template and the heater falls to managing extend neck; the import that falls to managing extend neck contacts with the outlet of heater; the outlet that falls to managing extend neck is corresponding with mould; described heater comprises being installed in puts bar and chain stay on the heated holder; driving chain is installed in the chain stay; putting conveying plastic bottle tube between bar and the driving chain; putting bar contacts with the plastic bottle-pipe baffle plate; it is characterized in that installing in the driving chain locating friction wheel; the locating friction wheel stretches between the operating plastic bottle-pipe and with the plastic bottle-pipe head and contacts, and the locating friction wheel has rotating device.
The tubular type stretch blow machine locating friction that falls of the present utility model is carried heater, rotating locating friction wheel has been installed in driving chain, rotational positioning friction pulley one is to stretch between each only operating plastic bottle-pipe the bottle pipe is located, make each bottle pipe heat certain spacing distance that remains in service, rotating device has been arranged, pipe friction makes bottle pipe produce rotation in operation to bottle, heats effective.
