Description

Large-scale double-station plastic blowing machine

Technical field:

The present invention relates to the used equipment of a kind of blowing moulding, particularly a kind of double-station plastic blowing machine.

Background technology:

Blow moulding machine commonly used, mostly be single station structure, i.e. opposed clamping of die head, its running is, after extruding pipe from die head, go through matched moulds-air blowing-cooling forming-operations such as die sinking blanking, to this moulding flow process of blanking, die head will stop feed and extrude operation at above-mentioned matched moulds, obviously, the blow moulding machine of this moment is to possess the continuous feeding ability is arranged, but has to wait for above-mentioned matched moulds to the finishing of blanking flow process, thus the loss of time of causing invalid wait; At this problem, in order to improve the operating efficiency of blow moulding machine, the technical scheme of a kind of double-station plastic blowing machine of dealer's developmental research, the structure of this blow moulding machine includes frame, feed system and die head, two clampings, two covers are passed the drive unit of clamping, compositions such as following blowing apparatus and controller, during the blow moulding machine operation, one clamping runs to die head feeding position location under drive unit is passed, die head is extruded pipe and is entered mould, clamping action matched moulds, thereupon under drive unit is passed, leave die head, and along track to a side shifting to desired location, and connect blowing apparatus down, pipe is through blowing moulding in the mould, cool off the die sinking blanking, finish the moulding overall process of goods; At above-mentioned clamping when setting a side shifting; another clamping moves to the die head direction under its drive unit is passed; and run to die head feeding position location; this clamping will repeat above-mentioned same operation program; to finish the moulding overall process of another goods; a blow moulding machine; on the different station of two clampings; finish operations for forming; and this moment, die head can be realized continual charging basically in the two alternately operating process; can eliminate the invalid stand-by period of single station operation basically loses with blow moulding machine; improve the operating efficiency of blow moulding machine greatly, still, when double-station plastic blowing machine needs moulding large scale goods; existing blow moulding machine structure will be brought bigger difficulty; because along with the product size strengthens, mould; template and relevant device (as hydraulic cylinder etc.) physical dimension strengthens, and construction weight obviously increases; corresponding supporting member also need be strengthened, consequently:

1, the double clamping is to move with the conversion of station, and the assembly that these sizes, weight are all bigger is moving link, structure complicated not only, and also the institute's energy requirement that drives these members also increases greatly;

2, make the difficulty increase of these large-scale moving links, its corresponding cost of manufacture also improves thereupon;

3, control the accurate location of these large-scale moving links, with the normal conveying pipe that guarantees die head and the synchronous operation of following blowing apparatus, its relevant art requirement is obviously far above light equipment, so equipment cost and operation funds also will increase.

For these reasons, how improving the structure and the performance of existing double-station plastic blowing machine, make it can adapt to efficient, the economic operations for forming of large scale blow-molded article, is the technical problem that present technique field dealer can't avoid.

Summary of the invention:

Technical problem to be solved by this invention is, a kind of improved large-scale double-station plastic blowing machine is provided, and it can simplify the structure of blow moulding machine, saves the energy of operations for forming, and can reduce the cost of manufacture and the use cost of blow moulding machine significantly.

The technical scheme that the present invention solves the problems of the technologies described above employing is:

Large-scale double-station plastic blowing machine includes frame; clamping; following blowing apparatus; die head and controller; frame and clamping are arranged on the common bed; clamping comprises a left side; right two groups; correspondence is provided with blowing apparatus down on clamping; also be provided with die head on the frame; controller connects control respectively through lead clamping; following blowing apparatus and die head; be characterized in: on frame; be positioned at the top of clamping; be provided with two clamping die heads and send the manipulator of pipe; the left side that track that the anchor clamps of manipulator move and guiding clamping template move; right guide rail is vertical laying, the left side of clamping; right clamping is set with a left side respectively; the left side of right guide rail; right base is to be fixedly installed on to be fixed on the common bed.During operation, the pipe that die head is sent moves away die head and sends to a clamping after by a manipulator clamping, and this clamping is equipped with down blowing device and carries out follow-up moulding overall process; And when after an above-mentioned manipulator clamping, moving; another manipulator moves; and after last manipulator leaves die head; another pipe that the clamping die head is sent continuously; and this pipe sent to another clamping; same this clamping is equipped with another following blowing apparatus and carries out follow-up moulding overall process, realizes the large-scale product blowing operation of double.

The present invention transfers the technical scheme that pipe is realized the double blow molding with manipulator; replace the mode of existing double-station plastic blowing machine with the blow molding that moves moulds; promptly with simple in structure; size is little; in light weight; manageable manipulator opens; clamping; move and wait action; replace size; weight is big; the technical scheme that the clamping that difficulty is controlled alternately moves; its effect is: simplify the alternately structure of mobile member; improve the manufacture craft of respective members; the cost of manufacture of reduction equipment; the running energy consumption of micromanipulator is little; get rid of large-scale component and move the great defective of energy consumption; micromanipulator can realize conveniently that die head send pipe; the control of clamping and following blowing apparatus; operating technology requires and expense all can descend significantly, and the present invention is large-scale double-station plastic blowing machine economy and the splendid technical scheme of practicality.
