Abstract
The utility model discloses an air nozzle film blowing device. The air nozzle film blowing device comprises a rack (4), a rotary drum (2) and a rotary drum motor (1); a spindle head (35) and a wall drum (36) connected with each other are arranged on rotary drum shaft of two ends of the rotary drum (2) by an air nozzle arm (31); an air flue (30) is arranged in the spindle head (35) and the wall drum (36); a filter drum (37) is arranged on the inner wall of the wall drum (36); and the air nozzle (32) is connected to the lower part of the wall drum (36). According to the air nozzle film blowing device, the compressed air runs through the air flue in the spindle head and the wall drum and then is filtered by the filter drum and then is blown out from the wall drum, and then is blown to a drooling plastic film on the rotary drum, thus the plastic film is cooled evenly and has even thickness, and thus the quality of the plastic film is improved.
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, then form plastic sheet cup (bowl) through the operation such as the unreeling of hot forming mechanism, heating, moulding.Wherein, the film rolling operation is the film of extruding (salivation shape) to be carried out three rollers (a plurality of chill roll) rolling-type calendering process, and exists that film thickness is irregular, the problem of inhomogeneous cooling, has affected the quality of plastic sheeting.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, can make that film thickness is even, cooling uniform tuyere blown film device and provide a kind of.
Objects of the present invention are achieved through the following technical solutions: tuyere blown film device, comprise frame, cylinder, Rolling motor, by the tuyere arm, connected spindle nose and wall cylinder are housed on the drum shaft at described cylinder two ends, are provided with the air channel in this spindle nose and wall cylinder, and on the inwall of wall cylinder, filter cylinder are housed; Tuyere is equipped with in the bottom of described wall cylinder.
After adopting structure of the present invention, compressed air by the air channel in spindle nose and wall cylinder after, then blow out from the wall cylinder through the filtration of filter cylinder, then blow to salivation shape plastic sheeting on pressure roller by tuyere, make it evenly cooling and make its even thickness, thereby improved the quality of plastic sheeting.
Description of drawings
Fig. 1 is the structural representation of tuyere blown film device of the present invention.
Fig. 2 is that A in Fig. 1 is to view.
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, tuyere blown film device of the present invention, comprise frame 4, cylinder 2 (containing drum shaft, intermediate connecting component), Rolling motor 1, by tuyere arm 31, connected spindle nose 35 and wall cylinder 36 are housed on the drum shaft at described cylinder 2 two ends, be provided with (intercommunication) air channel 30 in this spindle nose 35 and wall cylinder 36, and filter cylinder 37 is housed on the inwall of wall cylinder 36; The bottom of described wall cylinder 36 is connected with tuyere 32 (also can claim air knife).
Wherein, bearing 33 and back-up ring 34 are housed between tuyere arm 31 and spindle nose 35; The two ends of wall cylinder 36 are connected with spindle nose 35; The air outlet of filter cylinder 37 is consistent with the air-out direction of tuyere 32.Be provided with some exhaust vents 3 on described wall cylinder 36 and at tuyere 32 places.The width of described tuyere 32 should be suitable with the width of cylinder 2.Described tuyere 32 comprises the tuyere lower lip 38 and tuyere upper lip 39 of formation (necessarily) angle, and wherein the angle of tuyere upper lip 39 can be regulated, to adjust what of air quantity.Support for tuyere can be had preferably, in the bottom of described tuyere 32, pinch roller 40 is housed, this pinch roller 40 is attached on the surface of cylinder 2.
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 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 cylinder by tuyere 32 again, cylinder is driven by Rolling motor and rotates, thereby makes salivation shape plastic sheeting evenly cooling and make its even thickness.
