Part among the figure, the title of parts and numbering thereof: frame 10, carving knife 11, firing equipment 15, slide plate 12, sliding plate support 14, U type groove 16, heat-proof device 13, cover to axle 20, slide plate adjust slide block 21, cut knife rest 22, knife rest adjusts slide block 23, circular shaft 24, square shaft 25 and third wheel 26, position regulator 27, retainingf key 28.
The specific embodiment
Plastic membrane blowing production line, comprise by extruder, blown-film die, calibrator, flattening device, draw-gear, taking-up equipment the streamline that forms is set in proper order, between the draw-gear of described plastic membrane blowing production line and devices for taking-up, be provided with cutting device, cutting device comprises frame 10 and the carving knife 11 that is installed on the frame 10, and carving knife 11 is provided with firing equipment 15.Extruder 1 is extruded the material of plasticizing, by blown-film die 2 pipe embryos material is propelled the price of moulding, then through calibrator 3 with the film cooling and shaping, utilize draw-gear 5 tractions again, arrive cutting device, utilize the carving knife 11 on the cutting device that the film behind the cooling and shaping is cut, simultaneously because carving knife 11 is provided with firing equipment 15, with carving knife 11 heating, when carving knife 11 is cut film, utilize the branch otch welding fabrication of the temperature of carving knife 11 with film itself, the film of cutting welding fabrication at last batches by taking-up equipment 6, finally forms finished product.
In order to satisfy periosteum is cut into a plurality of films, described carving knife 11 is at least one.
Described cutting device is provided with slide plate 12, and slide plate 12 is installed on the frame 10, has the opening that adapts with carving knife 11 in the middle of the slide plate 12.Opening on the slide plate 12 is for when cutting film, and carving knife 11 cutter hubs stretch into slide plate 12 usefulness, and the size of opening just can stretch into carving knife 11 and be as the criterion.Film slips over slide plate 12, because having suppressed film, the frictional resistance between slide plate 12 and the film vertically cutting cross-direction shrinkage and the crimping that the back produces, make dual-side and the carving knife 11 of film after cutting keep excellent contact, can better reach like this and cut welding effect.
On described frame 10, cover is installed to axle 20, cover is provided with slide plate to axle 20 and adjusts slide block 21, slide plate 12 and slide plate are adjusted between the slide block 21 and are provided with sliding plate support 14, have U type groove 16 on the sliding plate support 14, and sliding plate support 14 is installed in slide plate by U type groove 16 and adjusts on the slide block 21.Adjust slide block 21 cover moving on axle 20 by slide plate, can adjust the position relation between slide plate 12 and the film; Because third wheel 26 is installed on the frame 10 and maintains static, the position that can adjust slide plate 12 and third wheel 26 by U type groove 16 concerns that this set can be adjusted the frictional resistance of film, adapts to different needs of work.
Described carving knife 11 is installed in cuts on the knife rest 22, corresponding, and cover is provided with knife rest to axle 20 and adjusts slide block 23, cuts knife rest 22 and is set in the knife rest adjustment slide block 23, cuts knife rest 22 and is provided with position regulator 27.Knife rest is adjusted slide block 23 and is provided with endoporus, cut knife rest 22 and be set in the endoporus that knife rest is adjusted slide block 23, and can adjust the relative position relation of cutting knife rest 22 and carving knife 11 and slide plate 12 by position regulator 27, after the adjustment, fixedly cut the position of knife rest 22 by retainingf key 28, thereby control the penetraction depth that carving knife 11 is cut film; Knife rest is adjusted slide block 23 and can be moved to axle 20 along cover, can control the position of cutting that carving knife 11 is cut film.
Described cover is provided with a square shaft at least to axle 20.This set can make slide plate adjust slide block 21 and knife rest adjustment slide block 23 both can successfully move on axle 20 at cover, can be fixed on cover easily on axle 20 by fixture again.
For conducting to, the heat that prevents the carving knife 11 after firing equipment 15 heating cuts knife rest 22, at carving knife 11 with cut and be provided with heat-proof device 13 between the knife rest 22.
The thickness of the cutting edge of carving knife 11 should be 3～5mm, prevents that film from the bonding phenomenon occurring after leaving cutting edge.
To produce zigzag in order preventing to cut and to cut edge, should use hard any industrial knife material, as adopting high-speed tool steel, it is sharp that the edge of a knife should keep.
As Fig. 1, Fig. 2 and shown in Figure 3, film by draw-gear arrives before taking-up equipment batches, to pass through cutting of cutting device, when film passes through the slide plate 12 of cutting device, because the effect of third wheel 26 and slide plate form certain frictional resistance between slide plate 12 and the film, thereby film will form certain force of strain, position by adjusting slide plate 12 can adjusting slider 12 and film between frictional resistance, and then adjust the tension force of film.Carving knife 11 is deep in work in the opening above the slide plate 12, carving knife 11 should with the slide plate cutting edge should with the working face keeping parallelism of slide plate 12.For the welding effect that obtains, guarantee that it is very important that welding cutter 11 is parallel to each other with the film movement direction, by the adjustment of the U type groove above the sliding plate support 14 16 with frame 10 positions relation, can guarantee carving knife 11 cutting edges parallel with the film movement direction, it is constant that the frictional resistance between slide plate 12 and the film keeps substantially.Carving knife 11 is provided with firing equipment 15, and firing equipment 15 can be the heating tube by cutter hub, also can be that alternate manner heats cutter hub, and the temperature of heating is generally 250-300 ℃.When film passed through slide plate 12, carving knife 11 cut divided thin film, because carving knife 11 itself has certain temperature (being generally 250-300 ℃), carving knife 11 also can will divide the film welding fabrication of incision simultaneously.Vertically cut cross-direction shrinkage and the crimping that the back produces because the frictional resistance between slide plate 12 and the film has suppressed film, making dual-side and the carving knife 11 of film after cutting keep excellent contact.Can reach welding fabrication effect preferably like this.The length of carving knife 11 should be between 200-250mm, and welding effect was better after such length can be able to make and cut.
This carving knife can be arranged a plurality of on cutting device, thereby reaches the purpose that an inflation film manufacturing machine is gone out a plurality of material volume films.As: before the improvement, produce the bag of 310*0.02 (the folding footpath is 210mm, and thickness is 0.02mm) and use film, the membrana oralis diameter is elected φ 60 as, and screw speed is 70n/min, and hauling speed is 700rpm, and the single face rolling had a daily output of 450kg/ days; Increase have the cutting device of a carving knife after, produce the film of bag using of the same specification of 310*0.02 (the folding footpath be 210mm, and thickness is 0.02mm), the membrana oralis diameter is elected φ 100 as, and screw speed is 70n/min, and hauling speed is 700rpm, two-sided rolling one goes out two, has a daily output of 690kg/ days.By contrast, cutting device has improved production efficiency greatly.
