Abstract
The utility model discloses a mechanism with adjustable tuyere positions, which comprises a tuyere arm (31), a shaft head (35), a walled cylinder (36) and a tuyere (32), wherein a sliding block (29) is mounted between the tuyere arm (31) and the shaft head (35); a threaded rod (45) is connected onto the sliding block (29), and is connected with a longitudinal hand wheel (49) through a longitudinal worm and gear component (43); a transverse worm and gear component (24) is mounted on the shaft head (35) and is connected with a transverse hand wheel (22); and a rotation locking piece (27) is mounted between the sliding block (29) and the shaft head (35). According to the mechanism with the adjustable tuyere positions, simultaneous automatic adjustment and locking of the shaft head, the walled cylinder and the tuyere in longitudinal heights and angles can be realized, thereby guaranteeing high qualities of plastic films (sheets).
Description
Technical field
The present invention relates to the plastic film shaper tool, specifically relate to a kind of device that plastic sheeting is carried out blown film.
Background technology
At present, the making of plastic sheet need first through plastic extrusion mechanism heating, extrude, the operation such as calendering, rolling and form plastic sheeting, form plastic sheet cup (bowl) through the operation such as the unreeling of hot forming mechanism, heating, moulding again.Wherein, film blown film operation is to utilize tuyere and compressed air to carry out blown film to the film of extruding (salivation shape) at cylinder to process, can not regulate but the position of its tuyere (comprising height and angle) is comparatively fixing, affect the quality of plastic sheeting (sheet material).
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of can be to the height of its tuyere, the tuyere position adjustable mechanism that angle can be regulated automatically.
Objects of the present invention are achieved through the following technical solutions: tuyere position adjustable mechanism, comprise tuyere arm, spindle nose, wall cylinder, tuyere, between described tuyere arm and spindle nose slide block is housed, is connected with screw rod on this slide block, this screw rod links to each other with vertical handwheel by vertical worm and gear assembly; At described spindle nose horizontal worm and gear assembly is housed, this horizontal worm and gear assembly links to each other with horizontal handwheel, and between slide block and spindle nose the rotation lock dog is housed.
After adopting structure of the present invention, by rotating vertical handwheel, horizontal handwheel, drive vertical worm and gear assembly, horizontal worm and gear assembly, make the screw rod rotation and the rising of band movable slider or decline, and spindle nose is rotated a certain angle, automatically regulate and locking when namely realizing vertical height of spindle nose, wall cylinder and tuyere and angle, thereby guaranteed the high-quality of plastic sheeting (sheet material).
Description of drawings
Fig. 1 is the mounting structure schematic diagram of tuyere of the present invention position adjustable mechanism.
Fig. 2 is the dextrad view of Fig. 1.
The specific embodiment
Below the present invention is described in further detail by accompanying drawing and embodiment.
With reference to Fig. 1, Fig. 2 as can be known, the present invention is applied to the tuyere position adjustable mechanism of plastic sheeting (sheet material) forming machine, comprise tuyere arm 31, spindle nose 35, wall cylinder 36, tuyere 32 (also can claim air knife), slide block 29 (about being two) is housed between described tuyere arm 31 and spindle nose 35, be connected with screw rod 45 on this slide block 29, this screw rod 45 links to each other with vertical handwheel 49 by vertical worm and gear assembly 43 (being contained in the worm gear case 41); At described spindle nose 35 horizontal worm and gear assembly 24 is housed, this horizontal worm and gear assembly 24 (being contained in the worm seat 23) links to each other with horizontal handwheel 22, and rotation lock dog 27 (it is by 28 controls of rotation shank of the key) is housed between slide block 29 and spindle nose 35.
Wherein, bearing 33 and back-up ring 34 also are housed between tuyere arm 31 and the spindle nose 35; Be provided with air channel 30 in this spindle nose 35 and the wall cylinder 36, and on the inwall of wall cylinder 36 filter cylinder 37 be housed.The two ends of wall cylinder 36 link to each other with spindle nose 35, are provided with some exhaust vents 3 on described wall cylinder 36 and at tuyere 32 places.The exhaust vent 3 of tuyere 32, wall cylinder 36 is facing to the cylinder of plastic sheeting (sheet material) forming machine, and 31 on tuyere arm is contained on the axle of this cylinder.
Described vertical worm and gear assembly 43 is left and right two groups, link to each other by connecting rod 48 between its worm screw, at this connecting rod 48 lifting lock dog 46 (it is by 47 controls of lifting shank of the key) is housed, to realize vertically regulating highly simultaneously and locking of spindle nose, wall cylinder and tuyere.
The operation principle of tuyere blown film device of the present invention is: compressed air by the air channel 30 in spindle nose 35 and the wall cylinder 36 after, blow out from the exhaust vent 3 of wall cylinder through the filtration of filter cylinder 37 again, blow to salivation shape plastic sheeting on the cylinder of plastic sheeting (sheet material) forming machine by tuyere 32 again, cylinder is then driven by Rolling motor and rotates, thereby salivation shape plastic sheeting is evenly cooled off and makes its even thickness.
When needs are regulated the height of tuyere, by rotating vertical handwheel 49, drive vertical worm and gear assembly 43 and connecting rod 48, make screw rod 45 rotations and 29 risings of band movable slider or decline, and by 46 lockings of lifting lock dog, realize that namely vertical height of spindle nose, wall cylinder and tuyere is regulated and locking simultaneously automatically.When needs are regulated the angle of tuyere, by rotating horizontal handwheel 22, drive horizontal worm and gear assembly 24, spindle nose 35 is rotated a certain angle, and by 27 lockings of rotation lock dog, realize that namely the angle of spindle nose, wall cylinder and tuyere is regulated and locking automatically.
