Description

The transmission device of parison heating system

Technical field

The utility model relates to the assembly of blow molding equipment, specifically is meant the transmission device of parison heating system in the blow molding equipment.

Background technology

Blow molding equipment has a track usually, and this track is provided with and can carries some carriers that parison advances in regular turn, when each carrier advances along the track bearing of trend, successively by some working positions, to finish operations such as heating, temperature adjustment, blow molding respectively.Because each working position is arranged in order by same track, workpiece in each working position action and on same track, carry out basically in the transmission between the working position, therefore, the distribution of each working position is subjected to great limitation, the distributing position of each working position can not design neatly, can take bigger space, and be unfavorable for each working position is debugged separately and keeped in repair.

If each working position can be designed to comparatively independent parts, be that action and the transmission each working position between of workpiece in each working position is not to carry out at same track, so, the distributing position that will make each working position is more flexibly with rationally, take up room and dwindle, and conveniently each working position is debugged separately and keeped in repair.

Particularly for the heating system of finishing heating process, its transmission device must be finished three elemental motions: one, parison is socketed on the carrier, and adopt manipulator to finish This move automatically at present, generally include move down, gripping, on action such as move, overturn, move down, its action is formed complicated, and cost is higher, and, if the accuracy of action is not enough, parison drops, and influences the normal operation of transmission system easily, and other parisons are affected; Two, the parison direction along ng a path is moved, so that carry out heating process through the thermal treatment zone; Three, for homogeneous heating, also must make the parison rotation usually.In the prior art, the realization of latter two action is comparatively complicated, unreasonable, two actions well can not be combined.

The utility model content

Another purpose of the present utility model is to solve parison in the prior art and moves the irrational shortcoming of realization with two actions of parison rotation.

Another purpose of the present utility model is to provide a kind of relatively independent, transmission device of being convenient to the parison heating system of debugging separately and keeping in repair.

The utility model adopts following technical scheme: the transmission device of parison heating system, at least comprise two pairs of hinge wheels and two chains, each connects by a rotating shaft respectively hinge wheel, two rotating shafts are parallel to each other, and be arranged at horizontal direction, each chain ring is around on two hinge wheels of the same side, connect by polylith strip gripper shoe between two chains, each gripper shoe is provided with the parison seat that outwards protrudes out, the horizontal component on two chain tops forms the parison thermal treatment zone, wherein the outside of a pair of hinge wheel forms the base district, and a pair of hinge wheel that is positioned at base district one side is connected rotationally with its rotating shaft, and another is fixedlyed connected with its rotating shaft to hinge wheel.When the parison seat turned to the side of hinge wheel, it axially was a horizontal direction, and in fact last base action is exactly that the parison along continuous straight runs is promoted, and it is socketed on the parison seat that is positioned at horizontal direction.As seen, last base action has obtained oversimplifying greatly, and, under this kind structure,, can not have influence on transmission device and other parisons even parison drops yet.

The transmission device of aforementioned parison heating system, its each gripper shoe is provided with several parison seats, and each parison seat is arranged on the gripper shoe rotationally by an axis of rotation, and each axis of rotation bottom is provided with drive sprocket; But be respectively equipped with the axle sleeve that a phase countershaft rotates in two rotating shafts of described connection hinge wheel, be fixedly connected with a fixed head between two axle sleeves, on this fixed head buncher is installed, is connected by the sprocket wheel chain gearing between the drive sprocket of the output shaft of this buncher and aforementioned each axis of rotation bottom.

Further, each gripper shoe is provided with four parison seats, the parison seat that is positioned at the upper level position forms four rows, the drive sprocket of the axis of rotation bottom of each parison seat is also corresponding lines up four rows, described sprocket wheel chain gearing comprises first, second, third driving chain and the drive sprocket that is connected with the buncher output shaft, mesh with aforementioned wherein two row's drive sprockets respectively first, second driving chain both sides, the 3rd driving chain and first, second driving chain are in transmission connection by coaxial sprocket, drive sprocket and the engagement of the 3rd driving chain outside.

As seen, two independently transmission system realizations are passed through in moving and rotating of parison respectively, can not interfere with each other also easier the maintenance.

Aforementioned each axis of rotation is connected with gripper shoe by two bearings, and two bearings lay respectively at the two sides of gripper shoe.

Aforementioned blow molding equipment send the base blowing device, its two braces that connect adjacent two chain links of chain are respectively equipped with the lug that protrudes out to the chain both sides, the end of each gripper shoe is fixed on four lugs by screw.

By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, the utility model has been simplified the last base action of heating system greatly, and, eliminated parison and come off the influence of transmission device and other parisons; Two, two independently transmission system realizations are passed through in moving and rotating of parison respectively, can not interfere with each other also easier the maintenance; Three, the utility model makes between other parts of heating system and blow molding equipment relatively independent, and space layout is designed neatly, is convenient to separately heating system partly be debugged and keeped in repair; Four, a pair of hinge wheel is fixedlyed connected with its rotating shaft, and another is connected with its rotating shaft rotationally to hinge wheel, can carry out the self adaptation adjustment to the error of two chains thus.
